Description:Field of the Invention


The present disclosure generally relates to filtration systems. Further, the present disclosure particularly relates to a rotary filtration apparatus for a sedimentation reservoir.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Various systems have been employed for filtration within sedimentation reservoirs to manage particulates and other forms of waste. Conventional filtration systems primarily rely on fixed screening units or submerged filtration devices to separate particulates from wastewater. Such systems typically incorporate stationary meshes or grids that remain submerged, allowing fluid to pass while capturing solid materials on the mesh surface. These systems have gained attention for their simplicity in construction and ease of deployment. However, stationary filtration systems often encounter significant challenges. These challenges include the buildup of debris on the filtration surface, which can reduce efficiency by obstructing the fluid flow, thus leading to frequent maintenance requirements.
Additionally, stationary filtration systems are associated with inconsistent filtration performance due to the non-uniform exposure of the mesh surfaces to the wastewater. In many cases, only certain sections of the filtration surface become clogged with particulates, while other sections remain underutilised. Such an imbalance often reduces the overall filtration efficiency and leads to quicker degradation of the filtration material due to concentrated stress on specific sections. Moreover, stationary filtration systems are less capable of handling fluctuating wastewater loads, especially during periods of high sedimentation or when large volumes of floating debris are present.
Other prior art filtration systems have incorporated movable components to address some of the issues associated with stationary systems. Such movable filtration systems utilise components that can rotate, vibrate or oscillate to promote more uniform exposure of the filtration surface. However, movable systems are frequently associated with complex mechanical assemblies, which require increased energy consumption and can introduce maintenance challenges of their own. For instance, mechanical drive systems employed to facilitate motion often suffer from wear and tear due to continuous operation, and the presence of moving parts introduces additional points of failure. Furthermore, systems incorporating rotational or oscillatory motion may still encounter uneven filtration as the movement of the filtration surface is often limited to a specific axis or direction, leaving certain areas prone to overloading with particulates.
Some filtration systems have sought to improve upon both stationary and movable designs by incorporating self-cleaning mechanisms. Such systems typically employ automated scrapers or brushes that periodically clear debris from the filtration surface. While self-cleaning mechanisms can extend the operational lifespan of the filtration material, they tend to introduce added mechanical complexity and are prone to operational issues such as jamming or insufficient cleaning performance. Additionally, self-cleaning systems often require a substantial amount of energy to operate and can be impractical for large-scale applications or environments with variable wastewater conditions.
In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and/or techniques for filtration within sedimentation reservoirs.

FIG. 1 illustrates a rotary filtration apparatus (100) for a sedimentation reservoir, in accordance with the embodiments of the present disclosure. In an embodiment, a rotational screening unit (102) is mounted to a vertical support rod (104) within the rotary filtration apparatus (100). The rotational screening unit (102) is constructed to revolve around said vertical support rod (104), allowing continuous movement in a circular motion. Said rotational screening unit (102) includes structural features that capture floating particulates present in a sedimentation reservoir. The mounting of the rotational screening unit (102) to the vertical support rod (104) provides a stable axis of rotation, while the movement of the unit facilitates the consistent collection of particulates from the fluid surface. The rotational movement enables the unit (102) to cover a broad area within the sedimentation reservoir, ensuring that floating debris is intercepted as the unit rotates. The rotation of the unit prevents accumulation of debris at one point and enables even distribution of filtered matter. The materials of the rotational screening unit (102) are selected to withstand prolonged exposure to liquid environments, ensuring durability and consistent performance throughout its operation. The design of the rotational screening unit (102) allows easy maintenance and cleaning, contributing to prolonged operational lifespan.
In an embodiment, a mesh array (106) is affixed to the rotational screening unit (102). Said mesh array (106) is arranged concentrically around the rotational screening unit (102) to allow fluid to pass through while capturing particulates. The structure of the mesh array (106) includes a series of interconnected wires or fibers that form openings of predetermined sizes, depending on the specific filtering requirements. The mesh array (106) provides a physical barrier that filters out debris and other solid particles from the fluid, while still enabling fluid passage.

The mesh array (106) is typically made from corrosion-resistant materials such as stainless steel or plastic polymers, chosen to withstand harsh environmental conditions, including chemical exposure and mechanical stress. Said mesh array (106) is replaceable and can be adjusted to different filtration specifications by modifying the mesh size or material composition, offering flexibility in various filtration applications.
In an embodiment, a drive assembly (108) interacts with the vertical support rod (104) to induce rotation of the rotational screening unit (102). Said drive assembly (108) may include mechanical components such as gears, belts, or motors that generate rotational force. The interaction between the drive assembly (108) and the vertical support rod (104) allows the rotational screening unit (102) to rotate consistently and smoothly around said vertical support rod (104). The drive assembly (108) is positioned to provide controlled and continuous rotation, ensuring that the rotational screening unit (102) maintains consistent exposure to the fluid within the sedimentation reservoir. The design of the drive assembly (108) takes into account the torque required to move the rotational screening unit (102) and the resistance posed by the fluid and debris. Said drive assembly (108) is constructed from durable materials capable of withstanding wear and tear resulting from continuous use in fluid environments. Maintenance of the drive assembly (108) is minimal, and said drive assembly (108) may include seals or lubricants to prevent water intrusion and ensure smooth operation.
In an embodiment, the rotational screening unit (102) intersects the vertical support rod (104) at an axial bearing interface, which facilitates smooth rotation with minimal friction. Said intersection at the axial bearing interface allows the rotational screening unit (102) to rotate efficiently around the vertical support rod (104) by reducing frictional resistance. The axial bearing interface is constructed from materials that minimize wear over time and provide stability during prolonged operation in the sedimentation reservoir. The positioning of said axial bearing interface ensures that the rotational motion of the screening unit (102) is not impeded by excessive mechanical drag, which could otherwise reduce its efficiency in capturing floating particulates. The interface supports the even distribution of forces during rotation, ensuring consistent exposure of the mesh array (106) to the fluid in the sedimentation reservoir. The integration of said axial bearing interface also helps in maintaining the alignment of the screening unit (102) with respect to the vertical support rod (104), promoting durability and consistent performance.
In an embodiment, the mesh array (106) is longitudinally aligned with a plurality of radial spokes extending from the rotational screening unit (102). Said radial spokes provide structural support to the mesh array (106) by holding it in a stretched configuration, ensuring that the mesh array (106) remains taut during operation. The arrangement of said radial spokes is designed to evenly distribute tension across the entire surface of the mesh array (106), preventing sagging or displacement that could affect the filtration performance. The radial spokes are typically constructed from materials that resist corrosion and mechanical stress, making them suitable for prolonged exposure to water and particulate matter in sedimentation reservoirs. Said radial spokes extend outward from the central axis of the rotational screening unit (102), ensuring that the mesh array (106) is held in place while allowing fluid to pass through. The configuration of the spokes and mesh array (106) provides structural integrity to the filtration system and supports efficient particulate capture during operation.
In an embodiment, the drive assembly (108) is peripherally engaged with a toothed ring coupled to the rotational screening unit (102). Said peripheral engagement enables the drive assembly (108) to transfer torque directly to the rotational screening unit (102), allowing for smooth and efficient rotation around the vertical support rod (104). The toothed ring is positioned around the circumference of the rotational screening unit (102), and the engagement between said toothed ring and the drive assembly (108) enhances rotational efficiency by providing a firm mechanical connection for torque transfer. The toothed ring is typically made from durable materials that can withstand repeated rotational forces and are resistant to wear caused by continuous use in a sedimentation reservoir. Said engagement allows the drive assembly (108) to generate sufficient force to rotate the screening unit (102) without slipping or mechanical failures, ensuring consistent filtration performance. The engagement also simplifies maintenance, as the toothed ring and drive assembly (108) are accessible for inspection or replacement if needed.
In an embodiment, the vertical support rod (104) is integrally affixed to a stabilizing bracket positioned within a base section of the sedimentation reservoir. Said stabilizing bracket provides structural support to the vertical support rod (104), ensuring that it remains vertically aligned during the operation of the rotational screening unit (102). The stabilizing bracket is secured to the base section of the sedimentation reservoir to provide a firm foundation for the vertical support rod (104), preventing movement or displacement caused by the rotational forces of the screening unit (102). The materials used for said stabilizing bracket are selected for their resistance to corrosion and mechanical wear, ensuring longevity in environments where the apparatus is exposed to water and debris. The stabilizing bracket is designed to distribute the weight and force exerted on the vertical support rod (104) evenly, minimizing stress points that could lead to mechanical failure. Said stabilizing bracket allows the vertical support rod (104) to function effectively as a central axis for the filtration apparatus.
In an embodiment, the mesh array (106) comprises a plurality of staggered apertures, with each aperture being dimensioned to create a gradient filtration effect. Said staggered apertures are arranged to progressively capture particles of varying sizes, improving the overall filtration efficiency of the rotary filtration apparatus (100). The gradient filtration effect ensures that larger particles are captured by the outer layers of the mesh array (106), while smaller particles are filtered by the inner layers, thereby reducing the risk of clogging and improving the flow of fluid through the apparatus. The staggered apertures are designed to maintain the structural integrity of the mesh array (106) while allowing efficient fluid passage. The materials used to construct said mesh array (106) are chosen to resist corrosion and withstand exposure to water and particulate matter, ensuring consistent performance over time. Said mesh array (106) can be tailored to specific filtration needs by adjusting the size and arrangement of the staggered apertures.
In an embodiment, the drive assembly (108) further comprises a speed modulation device, which adjusts the rotational velocity of the rotational screening unit (102) based on the density of particulates detected in the wastewater. Said speed modulation device monitors the density of particulates in the fluid and modulates the speed of the drive assembly (108) to optimize the filtration process. When the density of particulates increases, the speed modulation device slows down the rotation of the screening unit (102) to allow more time for the mesh array (106) to capture the particulates. Conversely, when the particulate density decreases, said speed modulation device increases the rotational speed of the screening unit (102) to maintain a consistent flow of fluid through the apparatus. The speed modulation device is designed to enhance the efficiency of the filtration process by adjusting the operation of the drive assembly (108) in response to changing environmental conditions within the sedimentation reservoir.
In an embodiment, the rotational screening unit (102) is further equipped with a scraper element positioned adjacent to the mesh array (106). Said scraper element is arranged to dislodge accumulated particulates from the surface of the mesh array (106) during the rotation of the screening unit (102). The scraper element is mounted in such a way that it makes contact with the mesh array (106) as the rotational screening unit (102) revolves, removing debris that may have adhered to the mesh. The continuous scraping action prevents the mesh array (106) from becoming clogged, allowing for uninterrupted filtration performance. The scraper element is constructed from materials that are durable enough to withstand repeated contact with the mesh array (106) while avoiding damage to the mesh. Said scraper element is designed to minimize maintenance requirements by preventing excessive buildup of particulates on the mesh array (106).
In an embodiment, the drive assembly (108) comprises a coupling unit that is releasably attached to the rotational screening unit (102). Said coupling unit facilitates easy detachment of the rotational screening unit (102) from the drive assembly (108) for maintenance, cleaning, or replacement. The releasable coupling unit is designed to provide a secure connection during operation while allowing for quick and efficient disassembly when necessary. The coupling unit is constructed from materials that can withstand the mechanical stresses associated with repeated attachment and detachment, ensuring long-term durability. Said coupling unit simplifies the process of performing routine maintenance on the rotary filtration apparatus (100), as the rotational screening unit (102) can be easily removed without the need for specialized tools or equipment.
In an embodiment, the mesh array (106) is coated with a hydrophobic layer to reduce the adhesion of particulates. Said hydrophobic layer is applied to the surface of the mesh array (106) to minimize the buildup of debris and prevent clogging. The hydrophobic properties of the coating ensure that water and other fluids are repelled from the surface of the mesh array (106), allowing particulates to be more easily removed during the rotation of the screening unit (102). The hydrophobic layer is designed to maintain its effectiveness over prolonged exposure to water and particulate matter, ensuring consistent filtration performance. Said hydrophobic coating can be applied using various methods, such as spraying or dipping, and is compatible with a range of materials used in the construction of the mesh array (106). The application of the hydrophobic layer helps to reduce maintenance requirements by preventing excessive accumulation of debris on the mesh array (106).
FIG. 2 illustrates the operation of a rotary filtration apparatus (100) within a sedimentation reservoir, in accordance with the embodiments of the present disclosure. The system introduces floating particulates from the sedimentation reservoir to a rotational screening unit (102) mounted on a vertical support rod (104). Said rotational screening unit (102) revolves around the vertical support rod (104), capturing floating particulates as it moves. The drive assembly (108) induces rotation in the screening unit (102), ensuring that the mesh array (106) affixed to the screening unit (102) is consistently exposed to the wastewater. Said mesh array (106), concentrically arranged, permits fluid passage while filtering particulate matter. The continuous rotation of the screening unit (102) enables consistent filtration, preventing stagnation and ensuring thorough wastewater purification.
In an embodiment, the rotary filtration apparatus (100) comprises a rotational screening unit (102) mounted to a vertical support rod (104), enabling continuous rotation for the purpose of capturing floating particulates in a sedimentation reservoir. Said rotational screening unit (102) revolves around the vertical support rod (104), allowing it to consistently interact with the fluid's surface, where floating debris tends to accumulate. The movement of the rotational screening unit (102) prevents the formation of stagnant zones within the reservoir, enabling continuous exposure of the mesh array (106) to fresh fluid. The rotation also promotes uniform filtration by ensuring that the entire surface area of the mesh array (106) is utilized, thereby reducing the risk of clogging and allowing uninterrupted fluid passage. The ability of said rotational screening unit (102) to consistently rotate around the vertical support rod (104) provides operational stability and consistent particulate removal, enhancing the overall effectiveness of the filtration process in various fluid environments.
In an embodiment, the rotational screening unit (102) intersects the vertical support rod (104) at an axial bearing interface, allowing smooth rotational motion with minimal friction. Said axial bearing interface reduces mechanical resistance, enabling the rotational screening unit (102) to rotate efficiently around the vertical support rod (104) without excessive wear or energy loss. The low-friction interaction at the axial bearing interface extends the operational lifespan of the system by minimizing the mechanical strain on both the rotational screening unit (102) and the vertical support rod (104). Additionally, the axial bearing interface promotes consistent and even movement, which ensures continuous exposure of the mesh array (106) to fluid and reduces the likelihood of uneven particulate capture. The intersection at the bearing interface further contributes to the system's reliability by providing a stable axis of rotation, essential for maintaining smooth operational performance over extended periods.
In an embodiment, the mesh array (106) is longitudinally aligned with a plurality of radial spokes that extend from the rotational screening unit (102). Said radial spokes support the mesh array (106) in a stretched configuration, ensuring that the mesh remains taut and effective in filtering particulate matter from the fluid. The radial alignment of said spokes ensures that the mesh array (106) maintains its structural integrity during the rotational motion of the screening unit (102). This configuration prevents sagging or deformation of the mesh, which could compromise the filtration process by allowing particulates to bypass the filtration surface. Additionally, the radial spoke arrangement distributes tension evenly across the mesh array (106), further enhancing its stability and functionality. The stretched configuration supported by the radial spokes optimizes the exposure of the mesh array (106) to the fluid, ensuring that maximum filtration occurs with minimal interruptions.
In an embodiment, the drive assembly (108) is peripherally engaged with a toothed ring that is coupled to the rotational screening unit (102), allowing for direct torque transfer. Said engagement facilitates smooth and consistent rotational motion by transferring mechanical energy from the drive assembly (108) to the rotational screening unit (102) with minimal slippage. The toothed ring provides a secure mechanical interface, which enhances the efficiency of torque transfer, ensuring that the rotational screening unit (102) rotates at a consistent speed. The peripheral engagement reduces the risk of mechanical failures by providing a robust connection between the drive assembly (108) and the rotational screening unit (102). This setup promotes sustained filtration performance, as the continuous rotation of the screening unit (102) allows for uninterrupted exposure of the mesh array (106) to fluid, preventing blockages and ensuring consistent particulate removal in various sedimentation environments.
In an embodiment, the vertical support rod (104) is integrally affixed to a stabilizing bracket positioned within the base section of the sedimentation reservoir. Said stabilizing bracket provides structural support to the vertical support rod (104), ensuring that it remains vertically aligned during the operation of the rotational screening unit (102). The stabilizing bracket is secured within the reservoir's base section, preventing lateral movement or misalignment of the vertical support rod (104) during the rotational motion of the screening unit (102). This structural stability allows for smooth and consistent rotation of the screening unit (102), as the vertical support rod (104) remains fixed in place, eliminating unwanted vibrations or oscillations. The stabilizing bracket's integration also ensures that external forces, such as fluid currents or debris impacts, do not affect the operational integrity of the vertical support rod (104), thus enhancing the overall reliability of the filtration system.
In an embodiment, the mesh array (106) comprises a plurality of staggered apertures that create a gradient filtration effect. Said staggered apertures are dimensioned to sequentially capture particulates of varying sizes, ensuring that both large and small particles are effectively filtered from the fluid. The gradient filtration effect improves the overall purification efficiency by capturing larger particles at the outer layers of the mesh array (106), while allowing smaller particles to be filtered by the inner layers. This layered approach prevents clogging of the mesh array (106), as particulates are gradually captured based on their size, reducing the likelihood of blockages. The staggered aperture configuration also promotes consistent fluid flow through the mesh array (106), allowing for uninterrupted operation over extended periods without the need for frequent maintenance or cleaning.
In an embodiment, the drive assembly (108) further comprises a speed modulation device that adjusts the rotational velocity of the rotational screening unit (102) based on the density of particulates detected within the wastewater. Said speed modulation device allows the system to adapt dynamically to varying particulate loads by increasing or decreasing the speed of the rotational screening unit (102) as needed. When a high density of particulates is detected, the speed modulation device slows the rotation to allow for more thorough filtration, giving the mesh array (106) more time to capture particulates. Conversely, when the particulate load is low, the speed modulation device increases the rotational speed, optimizing the filtration process by maintaining consistent fluid flow. This adaptive feature reduces energy consumption and prevents excessive wear on the system while maintaining optimal filtration performance under varying operational conditions.
In an embodiment, the rotational screening unit (102) is further equipped with a scraper element positioned adjacent to the mesh array (106). Said scraper element is arranged to dislodge accumulated particulates from the surface of the mesh array (106) as the rotational screening unit (102) revolves. The scraper element makes continuous contact with the mesh array (106), removing debris that would otherwise obstruct fluid flow and reduce filtration efficiency. The dislodging of accumulated particulates allows the mesh array (106) to maintain consistent filtration performance over time, preventing blockages that could require manual cleaning or system shutdown. The scraper element is constructed from materials that are resistant to wear and corrosion, ensuring that it can withstand repeated contact with the mesh array (106) without degrading the structural integrity of the filtration apparatus.
In an embodiment, the drive assembly (108) comprises a coupling unit that is releasably attached to the rotational screening unit (102), facilitating easy detachment for maintenance or replacement. Said coupling unit allows for quick and efficient disassembly of the rotational screening unit (102) from the drive assembly (108), enabling users to perform maintenance tasks such as cleaning or replacing worn components without requiring extensive disassembly of the entire system. The releasable coupling unit provides a secure mechanical connection during operation but can be easily disengaged when needed, reducing downtime and minimizing the labor required for routine upkeep. The coupling unit is designed to withstand repeated cycles of attachment and detachment, ensuring that it maintains a reliable connection even after multiple maintenance procedures.
In an embodiment, the mesh array (106) is coated with a hydrophobic layer to reduce the adhesion of particulates. Said hydrophobic layer minimizes the accumulation of debris on the mesh array (106), preventing clogging and maintaining consistent filtration performance throughout the operational cycle of the apparatus. The hydrophobic coating repels water and other fluids, allowing particulates to be more easily dislodged from the mesh array (106) during the rotation of the screening unit (102). This prevents the buildup of debris that could obstruct fluid flow and reduce the efficiency of the filtration process. The hydrophobic layer is applied in a manner that ensures long-lasting effectiveness, even when the mesh array (106) is exposed to harsh environmental conditions, such as constant contact with wastewater or sediment-laden fluids.
