Description:TECHNICAL FIELD
[0001] The present disclosure relates to a field of irrigation systems for growing plants. Moreover, the present disclosure relates to a pneumatic pumping system for irrigating plants and a method for irrigating plants using the pneumatic pumping system, specifically in hydroponics systems.
BACKGROUND
[0002] Irrigation plays a vital role in agriculture, horticulture, and hydroponics by ensuring that grown plants or crops receive the necessary hydration and nutrients. Effective irrigation methods are crucial for maximizing crop yield, maintaining plant health, and optimizing resource use. Conventional irrigation methods often rely on mechanical or gravity-based systems such as mechanical pumps or gravity-fed methods to manage nutrient delivery to the irrigation areas. However, the conventional irrigation methods often face challenges such as uneven distribution of nutrients and water, limited control over nutrient delivery, insufficient oxygenation of the nutrient solution, and the like. Furthermore, without adequate oxygenation, the nutrient solution may not provide optimal conditions for plant growth, potentially leading to reduced plant health and yield. Moreover, conventional irrigation methods suffer from various limitations, including poor mixing and aeration of the nutrient solution, dependence on electricity, and difficulties in controlling and monitoring the irrigation process. Additionally, the conventional irrigation methods also require components like air stones and separate pumps to achieve proper aeration, adding complexity and potential points of failure.
[0003] Certain attempts have been made to address the limitations of the conventional irrigation methods, which include the use of penumatic air pumps, automated control systems, and the like. However, such solutions often add complexity, increase energy consumption, and fall short of making the nutrient solution a balanced, non-colloidal solution and maintain the oxygen level in the nutrient solution. Thus, there exists a problem of how to provide constant and efficient nutrient delivery for the irrigation of plants while maintaining the desired oxygen level in the nutrient solution.
[0004] Therefore, in light of the foregoing discussion, there exists a need to overcome the aforementioned drawbacks associated with the conventional irrigation system and the conventional methods for irrigating plants using the irrigation system.

Further, the inclusion of the water inlet within the upper portion of the tank allows for easy and efficient introduction of the nutrient solution into the tank, thereby simplifying the process of filling the tank with the nutrient solution. Furthermore, the outlet, present at the exit of the tank ensures a controlled release of the nutrient solution from the tank to the irrigation area, thereby providing a proper distribution of the nutrient solution to the irrigation area. Moreover, the sparging tube, extending along the entire length of the tank, ensures an even distribution of the compressed air within the nutrient solution present inside the tank and also prevents the sedimentation of the nutrients inside the nutrient solution. The air injection controlled by the non-return valve ensures a precise control over the amount of air mixed into the nutrient solution, leading to efficient nutrient mixing and pressurization. Moreover, the introduction of the solenoid-operated NRV at the outlet also enables the pneumatic pumping system to maintain a one-way flow of the nutrient solution, thereby preventing backflow and preserving the integrity of the nutrient solution. Additionally, the pneumatic pumping system incorporates the control pipe chamber that monitors and regulates various parameters of the nutrient solution, thereby ensuring that plants in the irrigation area receive the optimal nutrient composition.

[0016] The following detailed description illustrates embodiments of the present disclosure and ways in which they can be implemented. Although some modes of carrying out the present disclosure have been disclosed, those skilled in the art would recognize that other embodiments for carrying out or practising the present disclosure are also possible.
[0017] FIG. 1 is a block diagram that depicts a pneumatic pumping system for irrigation, in accordance with an embodiment of the present disclosure. With reference to FIG. 1, there is shown the block diagram of the pneumatic pumping system 100 that includes a tank 102. The tank 102 further includes a water inlet 104 and an outlet 106. Furthermore, the pneumatic pumping system 100 includes a sparging tube 108, a non-return valve (NRV) 112, a solenoid-operated non-return valve (NRV) 114, a control pipe chamber 116, a hollow pipe 118, a pressure gauge 120, one or more pressure safety valves 122, an air release valve 124, and an automatic pressure release valve 126.
[0018] The tank 102 refers to a large receptacle or storage chamber configured to store a nutrient solution, mix or agitate the nutrient solution, and oxygenate or pressurize the nutrient solution with oxygen before delivering the nutrient solution to an irrigation area. In an implementation, the tank 102 is made from durable stainless-steel material that is compliant with food safety standards and ensures that the nutrient solution remains uncontaminated. In an example, the tank 102 can be made from SS304 stainless steel material. In another example, the tank 102 can be made from SS306 stainless steel material. In some implementations, the tank 102 is cylindrical in shape. In another implementation, the tank 102 may be square in shape. In yet another implementation, the tank 102 may be circular in shape. Furthermore, the tank 102 is resistant to corrosion and can be used for storing the nutrient solution for a longer period of time. The tank 102 is further configured to handle the introduction of compressed air, which agitates and oxygenates the nutrient solution within the tank 102.
[0019] The water inlet 104 refers to an opening or port located on the tank 102, that is designed for the introduction of water. In an implementation, the water inlet 104 is positioned at the top of the tank 102. In another implementation, the water inlet 104 may be positioned at any of the side walls of the tank 102. The water inlet 104 is equipped with a removable cap or plug that can be securely sealed to prevent leakage or contamination of nutrient solution. In an implementation, the water inlet 104 is compatible with various fittings or adapters such that the tank 102 can be connected to hoses, pumps, or other equipment for filling and maintenance of the tank 102.
[0020] The outlet 106 is configured to act as an exit of the nutrient solution from the tank 102. In an implementation, the outlet 106 is typically positioned at the lower part of the tank 102, to ensure that the nutrient solution can be completely and efficiently drained from the tank 102. In some implementations, the outlet 106 is securely connected with hoses or pipes, which directs the nutrient solution to the irrigation area. Furthermore, the outlet 106 may include fittings or connectors that ensure a tight seal to prevent leaks.
[0021] The sparging tube 108 refers to an elongated cylindrical tube that runs horizontally along the length of the tank 102, configured to introduce compressed air coming from the compressed air source to the tank 102. Further, the sparging tube 108 is partially disposed within the tank 102. The sparging tube 108 includes an open-end disposed outside the tank 102, connected to the compressed air source, such as an air pump, or an air compressor. The sparging tube 108 further includes a closed end disposed within the tank 102, and a plurality of small outlets 110 on surface of the sparging tube 108. The plurality of small outlets 110 is configured to allow compressed air to escape from the sparging tube 108 and enter the nutrient solution contained inside the tank 102.
[0022] The NRV 112 refers to a type of valve that is specifically designed to allow the compressed air from the compressed air source to flow in a single direction (i.e., towards the tank 102). The NRV 112 is coupled with the open end of the sparging tube 108 and configured to control the injection of compressed air into the tank 102 through the sparging tube 108. In an implementation, the NRV 112 can be a solenoid-operated NRV. Furthermore, the non-return function of the NRV 112 prevents any reverse flow of the compressed air and maintains the desired direction of flow of the compressed air from the compressed air source towards the tank 102.
[0023] The solenoid-operated NRV 114 refers to the type of valve that is specifically designed to allow the nutrient solution from the tank 102 to flow in a single direction (i.e., towards an irrigation area) with the control capabilities of a solenoid. The solenoid-operated NRV 114 is positioned at the outlet 106 of the tank 102 and configured to control the exit of the nutrient solution from the outlet 106 of the tank 102. Furthermore, the non-return function of the solenoid-operated NRV 114 prevents any reverse flow of the nutrient solution, thus maintaining the desired direction of flow of the nutrient solution from the tank 102 towards the irrigation area.
[0024] The control pipe chamber 116 refers to a specialized section within the pneumatic pumping system 100, positioned between the tank 102 and the outlet 106 and branching off from the outlet 106, which is responsible for managing and regulating the nutrient solution before the nutrient solution is delivered to the irrigation area. Moreover, the control pipe chamber 116 is also responsible for receiving the nutrients. In an implementation, the control pipe chamber 116 may include but not limited to sensors and instruments that monitor various parameters of the nutrient solution, such as pressure, temperature, flow rate, nutrient concentration, and the like. In another implementation, the control pipe chamber 116 may include various mechanisms to modify the composition or condition of the nutrient solution by mixing, aerating, or adjusting the concentration of nutrients in the nutrient solution to meet specific irrigation requirements.
[0025] The pneumatic pumping system 100 further comprises a hollow pipe 118, which is a hollow U-shaped pipe or tube, configured to regulate and distribute air pressure within the tank 102 to ensure an effective agitation, oxygenation, and delivery of the nutrient solution for irrigation. Furthermore, the U-shape of the hollow pipe 118 ensures a smooth and controlled flow of excess compressed air present inside the tank 102 towards the opening of the control pipe chamber 116, thereby preventing turbulence that could disrupt the stability of the nutrient solution. The hollow pipe 118 consists of two ends, where the first end is positioned towards the tank 102, and the second end is positioned towards an opening of the control pipe chamber 116.
[0026] The pressure gauge 120 is configured to monitor the air pressure inside the tank 102. In an implementation, the pressure gauge 120 is positioned at the top of the tank 102. Examples of the pressure gauge 120 may include but are not limited to an analogue pressure gauge, a digital pressure gauge, a glycerin-filled pressure gauge, a differential pressure gauge, a vacuum pressure gauge, a compound pressure gauge, and a wireless pressure gauge.
[0027] The one or more pressure safety valves 122 are configured to release excess air pressure from the tank 102, when the air pressure inside the tank 102 exceeds a predetermined threshold value. The predetermined threshold value for the air pressure inside the tank 102 is determined based on the operational requirements of the pneumatic pumping system 100 while considering factors such as the optimal pressure required for efficient agitation of the nutrient solution and delivery of the nutrient solution along with the safety limits of the tank 102 material to prevent damage or rupture. Examples of the one or more pressure safety valves 122 may include, but are not limited to, Spring-Loaded safety valves, Pilot-Operated safety valves, Balanced Bellows safety valves, Poppet-Type safety valves, Thermal Relief safety valves, and the like.
[0028] The air release valve 124 refers to a typical valve used in pumping, that is configured to release excess air pressure from the tank 102 when the air pressure inside the tank 102 exceeds a predetermined threshold value. Furthermore, the air release valve 124 acts as a safety mechanism to prevent over-pressurization of the pneumatic pumping system 100, which could potentially damage components of the pneumatic pumping system 100 or disrupt the optimal functioning of the irrigation process.
[0029] The automatic pressure release valve 126 refers to an automatic valve configured to automatically release excess pressure from the tank 102 when it exceeds a predetermined threshold. In an implementation, the automatic pressure release valve 126 may include a pressure-sensitive mechanism, typically involving a spring-loaded component or a diaphragm. The pressure-sensitive mechanism is calibrated to respond to a specific pressure threshold that represents the upper limit of safe operation for the tank 102.
[0030] There is provided the pneumatic pumping system 100 for irrigation, that includes the tank 102 comprising the water inlet 104 configured to receive the water. The water inlet 104 is positioned on the top of the tank 102 to allow easy access to the tank's storage for filling and maintenance. Furthermore, the water inlet 104 is configured to accommodate a secure and leak-proof connection of the tank 102 with various water supply sources. Moreover, the water inlet 104 facilitates a quick and efficient filling of the tank 102 with water, thereby minimizing downtime and ensuring that the pneumatic pumping system 100 is easily available for operation with minimal delay. In another implementation, the water inlet 104 also serves as a manual entry way or a human entry way, providing access to the interior of the tank 102. In such implementations, the diameter of the water inlet 104 may range from 50-200 cm. Moreover, the water inlet 104 allows for easy internal inspection, cleaning, and maintenance of the tank 102, which is crucial for ensuring the longevity of the tank 102 and hygiene of the pneumatic pumping system 100.
[0031] Furthermore, the pneumatic pumping system 100 includes the control pipe chamber 116 branching off from the outlet 106 of the tank 102, that is configured to receive nutrients. The control pipe chamber 116 may incorporate an inlet for nutrient injection that allows nutrients to be introduced inside the tank 102. In an implementation, the nutrients may include, but not limited to, a variety of macronutrients such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulphur (S), and the like which are required in larger quantities for fundamental plant processes such as protein synthesis, energy transfer, and cell division. In another implementation, the essential nutrients may contain but not limited to a variety of micronutrients such as Iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo), boron (B), chlorine (Cl), and the like which are useful in enzyme activation, photosynthesis, and overall plant health.
[0032] Furthermore, the tank 102 is configured to mix the received water with the received nutrients to form the nutrient solution inside the tank 102. The tank 102 is configured to prepare a homogeneous nutrient solution by evenly distributing the received nutrients with the received water in the tank 102 through several mechanism such as agitation, circulation, and the like. By virtue of mixing and preparing the nutrient solution directly within the tank 102, the pneumatic pumping system 100 ensures uniform distribution of nutrients throughout the nutrient solution, which ensures that the plants receive the same balanced nutrient concentration, promoting even growth across the entire crop. Moreover, the nutrient solution is formulated to meet the specific needs of the plants being grown, considering factors such as plant species, growth stage, and environmental conditions. In an example, for leafy greens like lettuce or spinach, the nutrient solution would be rich in nitrogen to promote lush foliage growth. In another example, for flowering plants such as tomatoes or peppers, the nutrient solution would contain higher levels of phosphorus and potassium during the fruiting stage to support flower and fruit development. In yet another example, for plants like succulents or cacti, the nutrient solution may be formulated with lower nitrogen and higher levels of micronutrients, as succulents and cacti typically grow in nutrient-poor environments. The nutrient solution is stored, agitated, and oxygenated before being delivered to the irrigation area. The balanced composition of various essential nutrients and water in the nutrient solution ensures that each plant receives an appropriate amount of water and nutrients essential for the uniform growth of the plants.
[0033] In an implementation scenario, the nutrient solution is subjected to high pressure inside the tank 102 by adding the compressed air. The high pressure inside the tank 102 makes the nutrients present in the nutrient solution dissolve more efficiently due to the presence of a high amount of oxygen inside the nutrient solution. Also, under higher pressure conditions, more oxygen is stabilized within the nutrient solution, ensuring that the plants receive an adequate and continuous supply of dissolved oxygen. Also, the increased availability of dissolved oxygen in the high-pressure condition supports better root health, faster nutrient uptake, and improved overall plant growth.
[0034] In an implementation scenario, the expansion of air pressure in the pneumatic pumping system 100 causes a cooling effect inside the tank 102. The cooling effect occurs when compressed air is introduced into the tank 102 through the sparging tube 108 and is allowed to expand. As the compressed air expands, the excess compressed air inside the tank 102 is configured to absorb heat from the surroundings, thereby causing a reduction in temperature inside the tank 102. Moreover, the cooling effect inside the tank 102 maintains the nutrient solution inside the tank 102 at an optimal temperature, which is beneficial for plant growth and reduces the risk of thermal damage to the various components of the pneumatic pumping system 100.
[0035] Furthermore, the tank 102 of the pneumatic pumping system 100 includes the outlet 106. The outlet 106 acts as an exit for the tank 102 and is configured to discharge the nutrient solution from the tank 102.The outlet 106, in conjunction with the solenoid-operated NRV 114 ensures that the nutrient solution is delivered at the right time and in the correct quantity directly to the irrigation area, thereby reducing waste and ensuring uniform distribution of the nutrient solution to the plants in the irrigation area.
[0036] Furthermore, the pneumatic pumping system 100 includes the sparging tube 108, partially disposed within the tank 102 and extending along the length of the tank 102. Moreover, the sparging tube 108 comprises the open end disposed outside the tank 102 and connected to the compressed air source, the closed end disposed within the tank 102, and the plurality of small outlets 110 on a surface of the sparging tube 108 configured to introduce compressed air to the tank 102. In an implementation, the sparging tube 108 is fixed along the length of the tank 102, such that the coverage of the sparging tube 108 within the nutrient solution inside the tank 102 can be maximized, such that the nutrient solution can be oxygenated at a higher rate. The open end of the sparging tube 108 is positioned outside the tank 102 and is connected to the compressed air source through a secure and controlled connection, which allows the controlled oxygenation of the nutrient solution.
[0037] Furthermore, the pneumatic pumping system 100 includes the NRV 112 coupled with the open end of the sparging tube 108 and is configured to control the injection of the compressed air into the tank 102 through the plurality of small outlets 110 present on the surface of the sparging tube 108. Moreover, the NRV 112 is configured to ensure unidirectional flow of compressed air and prevent backflow. Therefore, the inclusion of the NRV 112 provides precise control over the injection of compressed air into the tank 102, which is critical for achieving consistent agitation and oxygenation of the nutrient solution.
[0038] Furthermore, the pneumatic pumping system 100 includes the solenoid-operated NRV 114 positioned at the outlet 106 of the tank 102 and configured to control exit of the nutrient solution from the outlet 106 of the tank 102. Furthermore, the solenoid-operated NRV 114 includes a valve body, an electromagnetic solenoid, and a valve mechanism that moves to open or close the flow path of the nutrient solution. The electromagnetic solenoid refers to an electromagnetic coil that creates a magnetic field, when energized. The magnetic field is responsible for moving the valve mechanism between open and closed positions, thereby opening, or closing the solenoid-operated NRV 114. In an implementation, once the desired amount of the nutrient solution has been provided to the irrigation area, the electromagnetic solenoid deactivates, causing the solenoid-operated NRV 114 to close preventing any overflow of the nutrient solution. Additionally, the non-return feature of the solenoid-operated NRV 114 ensures that once the nutrient solution exits the tank 102, the nutrient solution cannot flow back into the tank 102, thus preserving the integrity of the pneumatic pumping system 100 and preventing any reverse flow of the nutrient solution, which could disturb the pressure balance within the tank 102. Therefore, the inclusion of the solenoid-operated NRV 114 in the pneumatic pumping system 100 provides precise control over the discharge of the nutrient solution from the tank 102, ensuring that the plants receive an appropriate amount of nutrients in a controlled manner.
[0039] In an implementation, the control pipe chamber 116 is configured to monitor, control, and modify a set of predefined parameters of the nutrient solution. The control pipe chamber 116 is configured to analyze the nutrient solution, as the nutrient solution flows through the control pipe chamber 116 after exiting the tank 102. In an implementation, the control pipe chamber 116 may include various sensors to monitor the set of predefined parameters. The set of predefined parameters may comprise nutrient concentration, pH levels, temperature, and the like. The nutrient concentration refers to the amount of essential nutrients dissolved in the nutrient solution, which directly affects plant growth. If the concentration of any of the nutrients in the nutrient solution is too high, plants may suffer from nutrient toxicity, leading to poor growth or damage. The pH levels measure the acidity or alkalinity of the nutrient solution. Different plants require different pH ranges for optimal nutrient absorption. For example, most plants require a pH range of 5.5 to 6.5 to absorb essential nutrients efficiently. Moreover, based upon the readings from various sensors, the pneumatic pumping system 100 can make real-time adjustments to the nutrient solution, such as adding additional nutrients, adjusting the pH, or modifying the temperature.
[0040] Furthermore, the pneumatic pumping system 100 is configured to agitate and oxygenate the nutrient solution by introducing compressed air through the sparging tube 108 and delivering the nutrient solution to an irrigation area in a pressurized form. In conventional hydroponics systems, the rate of oxygenation in the nutrient solution (i.e., the dissolved oxygen level) ranges from 6% to 8% by volume, which corresponds to approximately 6 to 8 mg/L (milligrams per liter) of dissolved oxygen present in the nutrient solution. However, the present disclosure aims to increase the rate of oxygenation in the nutrient solution by 10 to 15 mg/L, thereby providing an optimal environment for plants to grow, resulting in improved plant metabolism and growth. Moreover, the present disclosure provides a cost-effective solution as compared to the conventional hydroponics systems. The pneumatic pumping system 100 is configured to oxygenate and agitate the nutrient solution via single system i.e., the pneumatic pumping system 100, thereby eliminating the need for separate air pumps and mixers commonly used in conventional hydroponics systems. Additionally, the pneumatic pumping system 100 limits the use of electricity for oxygenating and agitating the nutrient solution, thereby ensuring consistent nutrient distribution and oxygenation while reducing energy consumption and operational costs. By the combination of agitation, oxygenation, and pressurized delivery of nutrient solution, the pneumatic pumping system 100 ensures that the nutrient solution present in the tank 102 is well-mixed and oxygen-rich, supporting optimal plant health and growth, leading to improved crop yields.
[0041] In accordance with an embodiment, the pneumatic pumping system 100 further comprises the hollow pipe 118 attached to the top of the tank 102, configured to regulate and distribute air pressure within an upper portion of the tank 102 by allowing excess air to escape. The excess air pressure inside the tank 102 can lead to uneven distribution of the nutrient solution, potential over-pressurization, or even structural damage to the tank 102. The hollow pipe 118 is configured to allow the excess air to escape from the upper portion of the tank 102 to the outer environment through a secondary air inlet positioned at the control pipe chamber 116. Thus, the hollow pipe 118 prevents the build-up of excess air pressure inside the tank 102, thereby regulating the internal environment of the tank 102 and ensuring that the nutrient solution is properly agitated and oxygenated.
[0042] In accordance with an embodiment, the pneumatic pumping system 100 further comprises an air release valve 124 configured to prevent the nutrient solution from air pockets and an automatic pressure release valve 126 configured to release excess pressure inside the tank 102. The air release valve 124 is configured to prevent the formation of air pockets within the nutrient solution. As, air pockets can disrupt the consistent flow and distribution of the nutrient solution, which is vital for the uniform irrigation of plants. Thus, by eliminating the air pockets, the air release valve 124 ensures smooth and uninterrupted delivery of the nutrient solution, thereby promoting optimal plant growth. The automatic pressure release valve 126 is configured to release excess pressure inside the tank 102 when the pressure exceeds safe operating limits. As, excessive pressure could potentially damage the pneumatic pumping system 100 and affect the quality of the nutrient solution. Thus, the automatic pressure release valve 126 ensures the safe operation of the pneumatic pumping system 100 by regulating and maintaining pressure inside the tank 102. The pneumatic pumping system 100 is configured to utilize a venturi effect when the air release valve 124 or the automatic pressure release valve 126 opens. The venturi effect refers to the reduction in the pressure of a fluid that occurs when the fluid flows through a constricted section of a pipe or valve. Similarly, when the air release valve 124 is opened, the pressure inside the tank 102 drops, allowing the nutrient solution to mix more effectively with the incoming air or additional liquid. The mixing of the received nutrients with water, driven by the pressure differential phenomenon enhances the distribution of oxygen and nutrients throughout the nutrient solution, leading to more efficient and uniform irrigation of the plants.
[0043] FIG. 2 is a diagram that depicts a top view of the tank 102 used in the pneumatic pumping system 100, in accordance with an embodiment of the present disclosure. FIG. 2 is to be understood in conjunction with the elements illustrated in FIG. 1. With reference to FIG. 2, there is shown a top view 200 of the tank 102. The tank 102 includes the water inlet 104 and the outlet 106. The top view 200 further depicts the control pipe chamber 116, the plurality of a pressure gauge 120, and the one or more pressure safety valves 122, the air release valve 124, and the automatic pressure release valve 126.
