Description

Technical Field

[0001] This invention relates to the field of wastewater purification technology, specifically to a wastewater filtration device for animal washing that is easy to clean. Background Technology

[0002] With the development of animal husbandry, the demand for cleaning livestock is increasing. However, cleaning livestock generates a large amount of wastewater, which includes hair, feces, feed residue and other impurities. Direct discharge of such wastewater can easily pollute the environment. Therefore, it is necessary to treat the wastewater. Traditional animal cleaning wastewater treatment methods mainly use sedimentation tanks or septic tanks, which have problems such as large footprint and low treatment efficiency.

[0003] In response to the characteristics of animal cleaning wastewater treatment, utility model patent CN216164337U discloses an animal cleaning device for livestock breeding. While facilitating cleaning, the wastewater containing debris seeps into the drainage trough through a grid. The wastewater flows down the slope into the water inlet pipe, is filtered by the filter box, and is then lifted by the water pump, achieving the effect of waste utilization. This reduces the problem of large land area occupied by wastewater treatment ponds in traditional methods, and can further reduce water waste and improve water resource utilization.

[0004] However, such filtration and circulation equipment often suffers from problems such as easy clogging and inconvenient cleaning and maintenance during use, making it difficult to meet the requirements of efficient and environmentally friendly cleaning. In particular, a large amount of animal hair tends to accumulate in the drain holes and filter screens during the cleaning process, causing the filter screens to clog easily and requiring frequent cleaning, which affects the continuous operation of the equipment. While simply using large-grid, large-area filter plates to delay clogging is cumbersome and labor-intensive during the later cleaning process, it is difficult to promote its application in small and medium-sized farms. Summary of the Invention

[0005] The purpose of this invention is to provide an animal cleaning wastewater filtration device that is easy to clean, so as to solve the problems of easy clogging and inconvenient cleaning and maintenance of animal cleaning wastewater filtration devices mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An easy-to-clean animal washing wastewater filtration device includes a washing platform and a water treatment tank, with a drain outlet provided between the washing platform and the water treatment tank.

[0008] An elastic filter is provided on the inner side of the drain outlet, and a lifting drive rod is provided through the middle of the elastic filter. The top of the lifting drive rod is a lifting movable seat, and a cleaning nozzle is installed on the upper end of the lifting movable seat.

[0009] The lifting drive rod and the lifting movable seat together form a lifting structure at the elastic filter, and side cleaning brushes are evenly distributed along the outer edge of the lifting movable seat.

[0010] The water treatment tank is equipped with a filter frame inside, and the filter frame is located below the drain outlet.

[0011] The filter frame is a cylindrical structure and is horizontally arranged. Inside the water treatment tank, the filter frame rotates with its central axis as the axis.

[0012] A fixed cleaning brush is provided between the filter frame and the side wall of the water treatment tank, and the fixed cleaning brush is installed on the side wall of the water treatment tank and is in contact with the outer surface of the filter frame.

[0013] A reciprocating transmission mechanism is provided between the side end of the filter frame and the lifting drive rod, and the rotation of the filter frame and the lifting movement of the lifting drive rod form a synchronous driving structure through the reciprocating transmission mechanism.

[0014] Preferably, the elastic filter sheet has an overall funnel-shaped structure, and the main body of the elastic filter sheet includes an annular fitting part, a movable protrusion part, and filter holes;

[0015] The annular fitting part is fixed at the drain outlet, and the movable protrusion is located in the middle of the annular fitting part, and the filter holes are evenly distributed from the annular fitting part to the movable protrusion.

[0016] Using the above technical solution, the active protrusion protrudes upward during cleaning, and the hair in the water flow is relatively concentrated in the lower layer of the protrusion. This allows the protrusion structure of the elastic filter to effectively prevent a large amount of hair from completely clogging the drain outlet during animal cleaning.

[0017] Preferably, the top of the movable protrusion has an elastic opening, and the lifting drive rod is movably inserted through the elastic opening. Furthermore, the diameter of the lifting movable seat is larger than the diameter of the elastic opening, and the overall diameter of the lifting movable seat and the side cleaning brush is greater than or equal to the maximum diameter of the movable protrusion.

[0018] Using the above technical solution, after the initial cleaning is completed, the lifting movable seat moves down with the lifting drive rod, pressing down on the upward-protruding movable protrusion. At the same time, the side cleaning brush brushes the filter holes on the surface of the elastic filter, cleaning the dirt on the surface of the elastic filter in a synchronized manner, reducing additional post-cleaning work.

[0019] Preferably, the upper and lower surfaces of the filter frame are a filter screen plate and a fixing plate, respectively, and both the filter screen plate and the fixing plate are arc-shaped structures that are consistent with the curvature of the outer ring of the filter frame.

[0020] Using the above technical solution, a complete cylindrical filter frame is formed by a filter screen and a fixing plate. The corresponding working conditions of the filter screen and the fixing plate are switched by rotating the cylindrical filter frame. At the same time, the fixed cleaning brush can be used to clean the surface of the filter frame synchronously while rotating.

[0021] Preferably, the filter screen and the fixed plate respectively form a filtration structure and a sewage guiding structure corresponding to the lifting and lowering conditions of the lifting drive rod, and the filter screen rotates to the top to lift the lifting drive rod synchronously.

[0022] Using the above technical solution, during cleaning, the lifting drive rod raises the filter screen to the upper side, and the filter screen, together with the elastic filter sheet, performs rapid double filtration. At the same time, the irregular structure of the filter screen and the elastic filter sheet can effectively prevent animal hair from accumulating and causing blockage. After the cleaning is roughly completed, the lifting drive rod lowers, and the sewage mixed with hair falls directly down. At the same time, the filter screen rotates downwards and, together with the fixed cleaning brush, effectively prevents hair from accumulating on the surface of the filter screen.

[0023] Preferably, the main body of the water treatment tank is divided into a circulating water tank and a sewage tank. The sewage tank is located in the middle of the water treatment tank and is used to receive the hair-containing sewage that falls after the cleaning is completed by the side cleaning brush and the fixed cleaning brush. The circulating water tank is located at the side of the water treatment tank and is used to receive the filtered sewage that flows out from the side of the fixed plate after being filtered by the elastic filter and the filter screen during cleaning.

[0024] Using the above technical solution, during cleaning, the water that is quickly filtered can flow from the side to the circulating water tank along the guide water trough structure formed by the fixed plate below, so that it can be recycled as needed. When discharging sewage after cleaning, the fixed plate rotates to the top, which prevents hair from being left on the surface of the filter screen, while the sewage containing hair slides over the fixed plate and falls directly into the sewage tank.

[0025] Preferably, a circulating water pump is installed at the circulating water tank, and a water supply pipe is connected between the circulating water pump and the cleaning nozzle to form a water supply path.

[0026] By adopting the above technical solution, and through the cooperation of the circulating water pump and the water supply pipe, the cleaning nozzle can further utilize the water that has been rapidly filtered for recycling, thereby improving the water resource utilization rate and effectively reducing water waste.

[0027] Preferably, the main body of the reciprocating transmission mechanism is a movable connecting rod, and the upper and lower ends of the movable connecting rod are respectively provided with a connecting shaft and an eccentric shaft. The connecting shaft is movably connected to the lower end of the lifting drive rod, and the eccentric shaft is eccentrically set at the side end of the filter frame.

[0028] By adopting the above technical solution, the synchronous transmission structure of the linkage reciprocating transmission mechanism forms a synchronous drive structure for the rotation of the filter frame and the lifting of the lifting drive rod, which has good coordination.

[0029] Preferably, a drive motor is installed on the top of the side end of the water treatment tank, and a drive gear is provided at the output end of the drive motor. A transmission gear ring is coaxially provided on the side end of the filter frame, and the drive gear and the transmission gear ring form a meshing transmission structure.

[0030] By adopting the above technical solution, a waterproof motor is used for driving, and in conjunction with the reciprocating transmission mechanism of the linkage, only a single motor is needed to complete the linkage adjustment of the entire mechanism, eliminating the need for additional drive equipment, thus saving energy and increasing efficiency.

[0031] Preferably, there are multiple drain outlets, which are evenly distributed in a single row along the cleaning platform. A lifting frame is provided below the drain outlets, and the lifting drive rods are all installed on the lifting frame.

[0032] By adopting the above technical solution, drainage outlets can be set according to the specifications of the cleaning platform, and synchronous adjustments can be made in conjunction with the lifting and movable frame, without affecting the normal operation of the overall mechanism.

[0033] In this invention, the elastic filter sheet has an overall funnel-shaped structure, including an annular fitting part, a movable protrusion, and filter holes. This allows impurities in wastewater to more easily accumulate in the movable protrusion, facilitating centralized filtration and cleaning. The funnel-shaped design also promotes rapid wastewater discharge. An elastic opening is provided at the top of the movable protrusion, through which a lifting drive rod is movably inserted. When the lifting drive rod raises the lifting seat, the side cleaning brush cleans the inner surface of the elastic filter sheet, shaking off attached impurities and effectively preventing clogging, thus achieving the self-cleaning function of the elastic filter sheet.

[0034] Furthermore, the filter frame has a cylindrical structure and is horizontally positioned, rotating around its central axis within the water treatment tank. This allows each part of the filter frame's outer surface to pass through the fixed cleaning brush sequentially during rotation, achieving thorough cleaning of the filter frame's surface and preventing clogging of the filter mesh.

[0035] Furthermore, a reciprocating transmission mechanism is installed between the side end of the filter frame and the lifting drive rod. The rotation of the filter frame and the lifting movement of the lifting drive rod are synchronously driven by the reciprocating transmission mechanism. This allows the rotation of the filter frame to not only achieve its own cleaning but also drive the lifting drive rod through the linkage mechanism, thereby driving the self-cleaning of the elastic filter sheet, making the cleaning process of the entire filtration system more efficient and coordinated.

[0036] Furthermore, the upper and lower surfaces of the filter frame are respectively a filter screen plate and a fixing plate, both of which are arc-shaped structures consistent with the outer ring curvature of the filter frame. The filter screen plate is used to filter sewage, while the fixing plate guides the sewage during the rotation of the filter frame, allowing the filtered sewage to flow smoothly into the circulating water tank, thereby improving the sewage treatment efficiency and recycling rate.

[0037] Furthermore, the main body of the water treatment tank is divided into a circulating water tank and a sewage tank. The circulating water tank is used to receive the filtered sewage, which is then transported back to the cleaning nozzles through a circulating water pump and water supply pipes to realize the recycling of water resources. The sewage tank is used to receive the hair-containing sewage that is swept up by the back cleaning brush and the fixed cleaning brush after cleaning, which is convenient for centralized treatment. The zoning design optimizes the sewage treatment process.

[0038] Furthermore, the elastic filter at the drain outlet, the lifting drive rod, the side cleaning brush, the filter frame inside the water treatment tank, the fixed cleaning brush, and the reciprocating transmission mechanism all work together to form an organic whole. The coordinated operation of these components allows the equipment to automatically clean and maintain itself while filtering wastewater, significantly reducing manual operation and maintenance costs, and improving the equipment's continuous operation capability and practicality.

[0039] Furthermore, the ingenious design of the linkage reciprocating transmission mechanism transforms the rotational motion of the filter frame into the lifting motion of the lifting drive rod, achieving synchronous drive of two different motion forms. This efficient transmission method not only ensures the normal operation of the equipment but also improves its overall performance and reliability.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] This invention features a dual anti-clogging filtration structure with an elastic filter sheet and a filter frame. During the cleaning process, the wastewater containing hair is first initially filtered through the elastic filter sheet at the drain outlet. The protruding structure of the elastic filter sheet ensures that even if some hair is retained during the cleaning process, it can avoid clogging. The wastewater flowing out of the drain outlet is further filtered through the filter frame, and the arc-shaped panel can also effectively reduce the accumulation of dirt on the surface.

[0042] This invention features a side cleaning brush lifting and cleaning mechanism that works in conjunction with the elastic filter to actively clean it. During the cleaning process, the lifting drive rod and the lifting movable seat can be raised and water can be supplied through the cleaning nozzle. When the lifting drive rod is retracted, the side cleaning brush can also work with the irregular structure of the elastic filter to press it down and flip it over to clean its surface. No manual cleaning is required; only the wastewater tank needs to be cleaned periodically, effectively reducing the accumulation of dirt on the surface of the filter structure.

[0043] This invention features a fixed cleaning brush rotating cleaning structure that assists in cleaning the filter frame. While the lifting drive rod is lifting, the filter frame is also rotating synchronously. The fixed cleaning brush on the side brushes the surface of the filter frame, facilitating auxiliary cleaning of the filter frame surface and reducing the need for manual cleaning later.

[0044] This invention features a reciprocating transmission mechanism that synchronously drives the lifting drive rod and the filter frame. During use, a single motor can drive the lifting drive rod and the cleaning mechanism at the filter frame synchronously, providing excellent synergy. No additional drive equipment is required, reducing equipment costs. Combined with a circulating water pump, it enables the recycling of water after rapid filtration, resulting in green energy saving, cost reduction, and efficiency improvement.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example 1:

[0056] Please see Figures 1-8 This embodiment provides a technical solution: an animal cleaning wastewater filtration device that is easy to clean, including a cleaning platform 1 and a water treatment tank 2, and a drain outlet 3 is provided between the cleaning platform 1 and the water treatment tank 2; there are 5 drain outlets 3, and the drain outlets 3 are evenly distributed in a single row along the cleaning platform 1, and a lifting frame 17 is provided below the drain outlets 3, and the lifting drive rods 5 are all installed at the lifting frame 17.

[0057] An elastic filter 4 is provided on the inner side of the drain outlet 3, and a lifting drive rod 5 is provided through the middle of the elastic filter 4. The top of the lifting drive rod 5 is a lifting movable seat 6, and a cleaning nozzle 7 is installed on the upper end of the lifting movable seat 6. The lifting drive rod 5 and the lifting movable seat 6 together form a lifting structure at the elastic filter 4, and side cleaning brushes 8 are evenly distributed on the outer edge of the lifting movable seat 6.

[0058] The elastic filter 4 has a funnel-shaped structure, and its main body includes an annular fitting part 41, a movable protrusion 42, and filter holes 43. The annular fitting part 41 is fixed to the drain outlet 3, and the movable protrusion 42 is located in the middle of the annular fitting part 41. The filter holes 43 are evenly distributed from the annular fitting part 41 to the movable protrusion 42. During cleaning, the movable protrusion 42 protrudes upward, and the hair in the water flow is relatively concentrated in the lower layer of the protrusion. This allows the protrusion structure of the elastic filter 4 to effectively prevent a large amount of hair from completely clogging the drain outlet 3 during animal cleaning.

[0059] A filter frame 9 is installed inside the water treatment tank 2, and the filter frame 9 is located below the drain outlet 3. The filter frame 9 is a cylindrical structure and is horizontally arranged. The filter frame 9 rotates inside the water treatment tank 2 with its central axis as the axis. A fixed cleaning brush 10 is installed between the filter frame 9 and the side wall of the water treatment tank 2, and the fixed cleaning brush 10 is installed on the side wall of the water treatment tank 2 and is in contact with the outer surface of the filter frame 9.

[0060] The upper and lower surfaces of the filter frame 9 are respectively a filter screen plate 91 and a fixed plate 92, and both the filter screen plate 91 and the fixed plate 92 are arc-shaped structures with the same curvature as the outer ring of the filter frame 9. The filter screen plate 91 and the fixed plate 92 form a complete cylindrical filter frame 9. The corresponding working conditions of the filter screen plate 91 and the fixed plate 92 are switched by rotating the cylindrical filter frame 9. At the same time, the fixed cleaning brush 10 can be used to clean the surface of the filter frame 9 synchronously when rotating. The filter screen plate 91 and the fixed plate 92 respectively form the filtration structure and the sewage guiding structure corresponding to the lifting and lowering working conditions of the lifting drive rod 5. When one side of the filter screen plate 91 rotates to the top, the lifting drive rod 5 is raised synchronously. During cleaning, the lifting drive rod 5 raises the filter screen 91 to the upper side, and the filter screen 91, together with the elastic filter sheet 4, performs rapid double filtration. At the same time, the irregular structure of the filter screen 91 and the elastic filter sheet 4 can effectively prevent the accumulation of animal hair and blockage. After the cleaning is roughly completed, the lifting drive rod 5 lowers, and the sewage mixed with hair falls directly down. At the same time, the filter screen 91 rotates downward and is brushed with the fixed cleaning brush 10 to effectively prevent hair from accumulating on the surface of the filter screen 91.

[0061] The main body of the water treatment tank 2 is divided into a circulating water tank 21 and a sewage tank 22. The sewage tank 22 is located in the middle of the water treatment tank 2 and is used to receive the hair-containing sewage that falls after the cleaning brush 8 and the fixed cleaning brush 10 have finished cleaning. The circulating water tank 21 is located at the side of the water treatment tank 2 and is used to receive the filtered sewage that flows out from the side of the fixed plate 92 after being filtered by the elastic filter 4 and the filter screen 91 during cleaning. During cleaning, the rapidly filtered water can flow from the side to the circulating water tank 21 along the guide water tank structure formed by the fixed plate 92 below, so that it can be recycled as needed. When discharging sewage after cleaning, the fixed plate 92 rotates to the top, so that hair is not left on the surface of the filter screen 91, and the hair-containing sewage slides over the fixed plate 92 and falls directly into the sewage tank 22. A circulating water pump 11 is installed in the circulating water tank 21, and a water supply pipe 12 is connected between the circulating water pump 11 and the cleaning nozzle 7 to form a water supply passage. With the cooperation of the circulating water pump 11 and the water supply pipe 12, the cleaning nozzle 7 can further utilize the water that has been rapidly filtered for recycling, thereby improving the water resource utilization rate and effectively reducing water waste.

[0062] A reciprocating transmission mechanism 13 is provided between the side end of the filter frame 9 and the lifting drive rod 5, and the rotation of the filter frame 9 and the lifting movement of the lifting drive rod 5 are synchronously driven by the reciprocating transmission mechanism 13.

[0063] The main body of the reciprocating linkage mechanism 13 is the movable linkage 131, with a connecting shaft 132 and an eccentric shaft 133 respectively located at the upper and lower ends of the movable linkage 131. The connecting shaft 132 is movably connected to the lower end of the lifting drive rod 5, and the eccentric shaft 133 is eccentrically positioned on the side of the filter frame 9. The synchronous transmission structure of the reciprocating linkage mechanism 13 provides a synchronous drive structure for the rotation of the filter frame 9 and the lifting of the lifting drive rod 5, exhibiting good synergy. A drive motor 14 is installed on the top side of the water treatment tank 2, and a drive gear 15 is provided at the output end of the drive motor 14. A transmission gear ring 16 is coaxially arranged on the side of the filter frame 9, and the drive gear 15 and the transmission gear ring 16 form a meshing transmission structure. By using a waterproof motor for drive, in conjunction with the transmission of the reciprocating linkage mechanism 13, only a single motor is needed to complete the linkage adjustment of the entire mechanism, eliminating the need for additional drive equipment and achieving energy saving and efficiency improvement.

[0064] Example 2:

[0065] This embodiment is a further optimization based on embodiment 1. In this embodiment, the annular bonding portion 41 of the elastic filter 4 is embedded with a piezoelectric ceramic sheet, which is connected to a high-frequency generator 18 with a working frequency of 20-40kHz.

[0066] Furthermore, the fixed cleaning brush 10 is equipped with an ultrasonic transducer, the vibration direction is perpendicular to the surface of the filter frame 9, and the power density is 0.5-2W / cm².

[0067] In this embodiment, the piezoelectric ceramic sheet is attached to the rubber base layer of the annular bonding part 41 with a thickness of 2mm, a driving voltage of 100V, and a frequency of 28kHz; the ultrasonic transducer is embedded in the nylon bristle base of the fixed cleaning brush 10 and generates micro-vibrations with a radial amplitude of 5μm when working.

[0068] Example 3:

[0069] To address the issues of delayed response and sudden shutdowns caused by reliance on manual judgment for equipment blockage in existing technologies, this embodiment adds an intelligent monitoring and automatic processing module to Example 1 or Example 2, enabling real-time perception and precise removal of blockage risks. The specific solution is as follows:

[0070] A Hall torque sensor is added to the output end of the drive motor 14. The Hall torque sensor is rigidly connected to the output shaft of the drive motor 14, and the sensor signal output end is connected to the PLC controller via a shielded cable. The measurement range of the Hall torque sensor is... The sampling frequency is ≥10Hz, which is used to collect the output torque data of the drive motor 14 in real time, reflecting the load changes during the rotation of the filter frame 9 and the lifting of the lifting drive rod 5.

[0071] Furthermore, the PLC controller is installed in the control box outside the water treatment tank 2. Its input terminals are connected to the Hall torque sensor, turbidity sensor and timing module respectively, and its output terminals are connected to the drive unit of the drive motor 14 and the lifting drive rod 5.

[0072] The PLC controller has a built-in congestion risk model, which is generated through training on historical data. The input parameters include:

[0073] Torque change rate: The fluctuation range of torque per unit time (5s);

[0074] Wastewater turbidity (NTU): Collected by a turbidity sensor installed downstream of drain outlet 3, reflecting the concentration of suspended impurities in wastewater;

[0075] Runtime: The continuous running time of the device recorded by the timing module; the model output is a congestion risk value (0-100), where 0-30 is low risk, 31-60 is medium risk, and 61-100 is high risk.

[0076] When the PLC controller determines that the blockage risk value is ≥60, the following synchronization action will be automatically triggered:

[0077] Filter frame 9 rotates in reverse: After receiving the command, the drive motor 14 switches the rotation direction and drives the filter frame 9 to rotate in reverse for 5-10 seconds. The fixed cleaning brush 10 and the filter frame 9 use reverse friction to peel off the impurities attached to the surface of the filter screen 91.

[0078] High-frequency oscillation of lifting drive rod 5: Lifting drive rod 5 enters high-frequency oscillation mode, with an oscillation frequency of 5-10Hz, an amplitude of ±5mm, and a duration of 8-15s. Through the high-frequency brushing of elastic filter 4 by side cleaning brush 8 and the elastic deformation of elastic filter 4, the blockage in filter hole 43 is removed.

[0079] The specific process is as follows:

[0080] The Hall torque sensor, turbidity sensor, and timing module continuously collect data and transmit parameters to the PLC controller every 1 second.

[0081] The PLC controller inputs real-time parameters into the congestion risk model, updating the risk value every second;

[0082] Tiered response:

[0083] Low risk (0-30): The equipment maintains normal operating status;

[0084] Medium risk (31-60): The controller issues a warning signal and increases the data sampling frequency to 20Hz;

[0085] High risk (≥60): Automatically triggers reverse rotation of the filter frame and high-frequency oscillation of the lifting drive rod until the risk value drops below 30 and normal operation resumes; if the risk value is still ≥60 after 3 consecutive cleanings, an audible and visual alarm is triggered to prompt manual intervention.

[0086] Through intelligent monitoring and adaptive processing, early intervention of congestion risks can be achieved, reducing manual operation and maintenance costs, avoiding efficiency losses caused by sudden downtime, and significantly improving the stability and reliability of equipment in continuous operation scenarios.

[0087] Example 4:

[0088] This embodiment is a further optimization based on embodiment 1. In this embodiment, the top end of the movable protrusion 42 is provided with an elastic opening 44, and the lifting drive rod 5 is movably inserted through the elastic opening 44. Furthermore, the diameter of the lifting movable seat 6 is greater than the diameter of the elastic opening 44, and the overall diameter of the lifting movable seat 6 and the side cleaning brush 8 is greater than or equal to the maximum diameter of the movable protrusion 42.

[0089] After the initial cleaning is completed, the lifting seat 6 moves down with the lifting drive rod 5, pressing down on the upward-protruding movable protrusion 42. At the same time, the side cleaning brush 8 brushes the filter holes 43 on the surface of the elastic filter 4, cleaning the dirt on the surface of the elastic filter 4 and reducing additional post-cleaning work.

[0090] When the lifting drive rod 5 moves the lifting movable seat 6 and the side cleaning brush 8 up and down, since the overall diameter of the side cleaning brush 8 is greater than or equal to the maximum diameter of the movable protrusion 42, the side cleaning brush will directly contact and rub against the inner or outer surface of the movable protrusion. This friction can clean the hair and impurities accumulated in the filter holes 43 on the movable protrusion 42 in real time, preventing the filter holes from being clogged and affecting the drainage efficiency, thus reducing the need for frequent manual cleaning.

[0091] The diameter of the lifting seat 6 is larger than the diameter of the elastic opening 44. When the lifting drive rod 5 is in a stationary or lowered state, the lifting seat will form a pressure sealing effect on the elastic opening 44. This prevents sewage from leaking directly from the gap between the elastic opening and the lifting drive rod, ensuring that sewage must be filtered through the filter hole 43 before being discharged. This avoids unfiltered sewage from directly entering the water treatment tank 2 and ensures the filtration effect. At the same time, the elastic characteristics of the elastic opening 44, combined with the movable passage of the lifting drive rod, allow the lifting drive rod to move freely up and down, and also allow it to fit against the surface of the drive rod through its own elasticity, further reducing the risk of leakage through gaps.

[0092] Contents not described in detail in this specification are prior art known to those skilled in the art. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
