Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a novel ozone catalytic oxidation tower for wastewater treatment. Background Technology

[0002] Ozone catalytic oxidation technology, under the action of a catalyst, uses ozone oxidation to completely degrade or transform recalcitrant organic components in wastewater within a short time, thereby purifying the water. Catalytic ozonation is a novel water treatment technology aimed at enhancing the oxidizing performance of ozone and improving its utilization efficiency. This technology utilizes a catalyst to synergistically oxidize ozone, reducing the activation energy or altering the reaction pathway, thus achieving deep oxidation and maximizing the removal of organic pollutants.

[0003] However, in existing technologies, after adding seasonings, the food to be processed inside needs to be stirred and mixed to ensure that the seasonings and food are fully mixed. For example, Chinese patent CN215365066U discloses a novel ozone catalytic oxidation tower for wastewater treatment, which is a vertical tower structure with a tail gas emission port at the top and a wastewater inlet at the bottom. The oxidation tower adopts a staged oxidation design concept, divided into a lower ozone catalytic oxidation zone and an upper ozone oxidation zone. From top to bottom, the tower contains a demister, a liquid spraying device, a packed bed, a secondary catalyst bed, a secondary ozone gas inlet pipe (equipped with a gas distribution plate), a primary catalyst bed, and a primary ozone gas inlet pipe (equipped with a gas distribution plate). A liquid internal circulation system is also provided in the upper part of the tower, with the liquid connected to the spraying device via a circulation pump. A wastewater discharge port is located in the upper middle part of the tower. This invention can effectively improve ozone utilization, increase the efficiency of organic matter degradation and removal in wastewater, and significantly reduce operating costs.

[0004] While the above-mentioned schemes have the advantages mentioned above, their disadvantages are as follows: as an important component in the industrial ozone water preparation process, the catalyst's own catalytic effect and the dosage added greatly affect the catalytic effect of ozone, which in turn affects the treatment of wastewater. Therefore, the dosage of catalyst added is crucial. However, the above-mentioned schemes and traditional catalyst adding devices mostly use manual intermittent addition or large-scale addition, which consumes a lot of manpower. Moreover, it is not possible to add the catalyst intermittently only during the ozone addition stage and add it again after the internal reaction to improve the catalytic reaction effect. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art where the catalyst addition process is labor-intensive and cannot be done intermittently only during the ozone addition stage, with the catalyst added again after the internal reaction to improve the catalytic reaction effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel ozone catalytic oxidation tower for wastewater treatment, comprising: an outer shell, a liquid inlet pipe fixedly connected to one side of the outer surface of the outer shell, an air inlet pipe fixedly connected to one side of the outer surface of the outer shell, an air inlet device fixedly connected to one end of the outer surface of the air inlet pipe, a first motor fixedly installed on the top of the outer surface of the outer shell, a second motor fixedly installed on the top of the outer surface of the outer shell, a storage silo fixedly installed inside the outer shell, a multi-layer heating tube fixedly installed on the top of the outer surface of the storage silo, a rotating shaft fixedly connected to the bottom of the outer surface of the multi-layer heating tube, multiple stirring blades fixedly installed on the outer surface of the rotating shaft, multiple cleaning scrapers fixedly installed at one end of the outer surface of each of the stirring blades, the rotating shaft being movably embedded inside the storage silo, a telescopic rod fixedly installed on the bottom of the outer surface of the storage silo, and a... The lower filter plate has an upper filter plate movably embedded inside the outer shell. The upper filter plate and the lower filter plate are movably connected. Both the upper and lower filter plates have multiple filter holes on their outer surfaces. The rotating shaft is movably embedded inside the upper filter plate and the lower filter plate. One end of the outer surface of the telescopic rod is fixedly connected to a connecting sleeve plate, which is movably fitted onto the outer surface of the rotating shaft. One side of the outer surface of the connecting sleeve plate is movably connected to an independent collar, which is movably fitted onto the outer surface of the rotating shaft. Multiple connecting rods are fixedly installed on the outer surface of the independent collar. One end of the outer surface of each of the multiple connecting rods is fixedly installed with a cleaning arm. Multiple cleaning brush heads are fixedly embedded inside each of the multiple cleaning arms. An adjusting ring is fixedly connected to the bottom of the outer surface of the independent collar, and multiple adjusting teeth are fixedly installed on the bottom of the outer surface of the adjusting ring.

[0007] In a preferred embodiment, a retaining ring groove is fixedly sleeved on the outer surface of the rotating shaft, and the adjusting retaining teeth are adapted to the retaining ring groove. A pressing and rotating device is provided on the top of the outer surface of the upper filter plate. The pressing and rotating device includes a pressing ring, an anti-rotation rod, a retaining head, an outer connecting ring, a spring, and a rotating ring groove.

[0008] The technical effect of adopting the above-mentioned further solution is that: the side of the pressure ring is provided with multiple clamps that are embedded in the inside of the rotating ring groove. When pressed down, the clamps press against the outer connecting ring to rotate. When the telescopic rod retracts, the pressure ring is pushed to reset under the elastic force of the spring. When reset, it also rotates at a small angle, thereby enabling the relative rotation of the upper filter plate and the lower filter plate. A single power source realizes the connection between the cleaning arm and the rotating shaft, as well as the mode adjustment of the upper filter plate and filter holes.

[0009] In a preferred embodiment, the anti-rotation rod is fixedly installed inside the housing, the anti-rotation rod is fixedly connected to the pressure ring, and the pressure ring is movably sleeved on the outer surface of the rotating shaft.

[0010] The technical effect of adopting the above-mentioned further solution is that the anti-rotation rod is located at the bottom of the cleaning arm to prevent it from getting stuck when rotating, and at the same time, it limits the pressure ring to ensure that the pressure ring can only move up and down and cannot rotate.

[0011] In a preferred embodiment, the outer connecting ring is fixedly installed on one side of the outer surface of the upper filter plate, and the rotating ring groove is formed on the inner wall of the outer connecting ring.

[0012] The technical effect of adopting the above-mentioned further solution is that the inner wall of the rotating ring groove is set as an asymmetrical groove on the upper and lower sides. When the pressing ring is pressed, it will drive the outer connecting ring to rotate. When the spring returns to the pressing ring, it will also drive the rotation of the moving angle.

[0013] In a preferred embodiment, the clamping head is fixedly mounted on the outer surface of the pressure ring, and the clamping head is movably embedded inside the rotating ring groove.

[0014] The technical effect of adopting the above-mentioned further solution is that the locking head, which is movably embedded inside the rotating annular groove, ensures the stability of the upper filter plate during rotation adjustment.

[0015] In a preferred embodiment, the spring is fixedly installed on the top of the outer surface of the upper filter plate, and the spring is movably connected to the pressure ring. The output shaft of the first motor is fixedly connected to a connecting seat, and the connecting seat is movably installed on the top of the outer surface of the heating multilayer tube.

[0016] The technical advantages of adopting the above-mentioned further solution are: the heating multilayer tube contains multiple coils of heating wire to heat the catalyst, and a third motor is embedded inside the heating multilayer tube to connect to the bottom rotating shaft to prevent the catalyst from getting damp. Furthermore, the catalyst that has already gotten damp can be heated to remove moisture and restore its decomposition function.

[0017] In a preferred embodiment, a connector is fixedly connected to one side of the outer surface of the connector, and a push plate is fixedly connected to one end of the outer surface of the connector. The push plate is slidably embedded inside the storage bin, and a rotating shaft is fixedly connected to the output shaft of the second motor.

[0018] The technical effect of adopting the above-mentioned further solution is that the device for pushing the catalyst from the storage silo to the stirring position is a push plate. As the connecting seat rotates, the push plate rotates, thereby pushing the catalyst to the stirring and feeding position, thus realizing the stirring before adding the catalyst and the periodic addition.

[0019] In a preferred embodiment, a connecting cylinder is fixedly installed inside the outer shell, and a rotating stirring device is movably connected to one end of the outer surface of the connecting cylinder. The rotating shaft is movably embedded inside the connecting cylinder and is fixedly connected to the rotating stirring device. An intermittent feeding plate is provided on one side of the outer surface of the storage bin.

[0020] The technical effect of adopting the above-mentioned further solution is that the connecting cylinder is fixed inside the outer shell to connect to the fixed gear in the middle position of the side of the rotating stirring device, and the rotating shaft drives the rotating stirring device to rotate. Two pairs of meshing large and small gears are provided on one side of the rotating stirring device. Both small gears are meshed with the fixed gear in the middle position. As the rotating shaft rotates and the middle gear is fixed, the large gears on both sides will be driven to rotate simultaneously, thereby driving the two stirring hands connected to the bottom to stir the catalyst and prevent the catalyst from clumping.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0022] 1. This invention, through the cooperation of a storage silo, a rotating shaft, a connecting cylinder, a rotating stirring device, and an intermittent feeding plate, achieves stirring before catalyst addition and periodic addition, avoiding catalyst agglomeration. It solves the problems in the prior art where the catalyst addition process consumes a lot of manpower and cannot be added intermittently only during the ozone addition stage, and the catalyst can be added again after the internal reaction to improve the catalytic reaction effect.

[0023] 2. This invention, through the combination of heating multi-layer tubes and storage silos, avoids the catalyst from getting damp, and can heat and dehumidify the catalyst that has already gotten damp, restoring its decomposition function for the second time. At the same time, it prevents the catalyst from clumping and ensures the catalytic effect of the catalyst.

[0024] 3. In this invention, by means of a telescopic rod and a pressing and rotating device, the upper filter plate is cleaned while the upper and lower filter plates, which originally performed the filtration function, are rotated and adjusted to serve as a sealing device for the bottom cavity of sewage through the extension and retraction of the telescopic rod, thereby achieving the cleaning of the upper filter plate and the suction out of the cleaned sewage.

[0025] 4. In this invention, the mixing blades and cleaning scrapers work together to fully mix the internal processing liquid while the mixing blades scrape off contaminants that may adhere to the inner wall of the outer casing. Attached Figure Description

[0038] 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.

[0039] Please see Figure 1-10This invention provides a technical solution: a novel ozone catalytic oxidation tower for wastewater treatment, comprising: an outer shell 1, a liquid inlet pipe 2 fixedly connected to one side of the outer surface of the outer shell 1, an air inlet pipe 3 fixedly connected to one side of the outer surface of the outer shell 1, an air inlet device 4 fixedly connected to one end of the outer surface of the air inlet pipe 3, a first motor 101 fixedly installed on the top of the outer surface of the outer shell 1, a second motor 102 fixedly installed on the top of the outer surface of the outer shell 1, a storage silo 6 fixedly installed inside the outer shell 1, a multi-layer heating tube 5 fixedly installed on the top of the outer surface of the storage silo 6, a rotating shaft 501 fixedly connected to the bottom of the outer surface of the multi-layer heating tube 5, a plurality of stirring blades 502 fixedly installed on the outer surface of the rotating shaft 501, and a plurality of cleaning blades 502 fixedly installed at one end of the outer surface of each of the stirring blades 502. A cleaning brush 503 and a rotating shaft 501 are movably embedded inside the storage bin 6. A telescopic rod 8 is fixedly installed at the bottom of the outer surface of the storage bin 6. A lower filter plate 701 is fixedly installed on the inner wall of the outer shell 1. An upper filter plate 7 is movably embedded inside the outer shell 1 and is movably connected to the lower filter plate 701. Multiple filter holes 702 are opened on the outer surfaces of both the upper and lower filter plates 701. The rotating shaft 501 is movably embedded inside the upper filter plate 7 and the lower filter plate 701. A connecting sleeve 801 is fixedly connected to one end of the outer surface of the telescopic rod 8. The connecting sleeve 801 is movably sleeved on the outer surface of the rotating shaft 501. An independent collar 802 is movably connected to one side of the outer surface of the connecting sleeve 801. A ring 802 is movably sleeved on the outer surface of the rotating shaft 501. Multiple connecting rods 803 are fixedly installed on the outer surface of the independent ring 802. A cleaning arm 804 is fixedly installed at one end of the outer surface of each connecting rod 803. Multiple cleaning brush heads 805 are fixedly embedded inside each cleaning arm 804. An adjusting ring 806 is fixedly connected to the bottom of the outer surface of the independent ring 802. Multiple adjusting teeth 807 are fixedly installed at the bottom of the outer surface of the adjusting ring 806. Since the oxidation tower itself processes wastewater, it is unavoidable that water molecules from the bottom processing process will permeate into the catalyst. Therefore, a multi-layer heating tube 5 is installed. The multi-layer heating tube 5 contains multiple coils of heating wire for heating the catalyst. A third... The motor is connected to the bottom rotating shaft 501. While the output shaft of the second motor 102 drives the stirring arm on the rotating stirring device 105 to stir, it can intermittently add catalyst to the catalytic region at the bottom of the outer shell 1. The catalyst addition pipe is embedded inside the outer shell 1, leading directly to the bottom of the outer shell 1 and close to the ozone addition end of the gas filling device 4, allowing for faster ozone catalysis. The stirring is implemented as follows: the rotating shaft 103 rotates under the drive of the output shaft of the second motor 102. The connecting cylinder 104 is fixed inside the outer shell 1 to connect to the fixed gear in the middle of the side of the rotating stirring device 105. The rotating shaft 103 drives the rotating stirring device 105 to rotate. Two pairs of meshing large and small gears are provided on one side of the rotating stirring device 105.Both small gears mesh with the fixed gear in the middle. As the rotating shaft 103 rotates, in conjunction with the fixed middle gear, the large gears on both sides are simultaneously driven to rotate, which in turn drives the two stirring handles connected to the bottom to stir the catalyst, preventing catalyst clumping. This, combined with the heating multi-layer tubes 5 on the storage silo 6, prevents the catalyst from getting damp. For catalysts that have already become damp, heating can be used to dehumidify them, restoring their decomposition function and preventing further clumping, thus ensuring the catalyst's catalytic effect. Simultaneously, the rotating shaft 103 passes through the fixed gear in the middle and connects to the intermittent feeding plate 106 at the bottom. The intermittent feeding plate 106 is a double-layer design; the bottom layer is fixed and does not rotate, while the upper layer rotates under the drive of the rotating shaft 103. The upper layer is equipped with a feeding port. The catalyst will only enter the catalyst pipeline through the feeding port when the rotating upper layer is aligned with the lower layer. The device that pushes the catalyst from the storage bin 6 to the stirring position is the push plate 601. As the connecting seat 603 rotates, the push plate 601 rotates, thereby pushing the catalyst to the stirring and feeding position. This achieves stirring before catalyst addition and periodic addition. At the bottom of the heating multilayer tube 5, the rotation of the rotating shaft 501 drives the bottom stirring blade 502 and cleaning scraper 503 to rotate, which fully stirs the internal processing liquid. At the same time, the stirring blade 502 scrapes off contaminants that may adhere to the inner wall of the outer shell 1. The top upper filter plate 7 and the lower filter plate 701 are added as wastewater. The filter structure is such that the upper filter plate 7 can rotate relative to the lower filter plate 701. The rotation is achieved by pressing. The extension and retraction of the telescopic rod 8 causes the connecting sleeve 801 and the independent collar 802 to press down, thereby locking the adjusting tooth 807 into the outside of the collar groove 9. This connects the connecting rod 803, the cleaning arm 804, and the rotating shaft 501. The rotation of the rotating shaft 501 then drives the cleaning arm 804 and the cleaning brush head 805 to scrape and clean the upper filter plate 7 after long-term use. To prevent contaminants from falling into the interior of the outer casing 1 after cleaning, filter holes 702 are provided that can be hidden after rotating a certain angle, blocking the sewage flow path. A water pump is added at the liquid inlet pipe 2 to pump the cleaned sewage. Pulled out from the top of the upper filter plate 7, the upper filter plate 7 rotates using the telescopic rod 8. The telescopic rod 8 extends and retracts, causing the adjusting teeth 807 to press down, which in turn presses down the pressure ring 11. Multiple locking heads 111 are located on the side of the pressure ring 111 and are embedded inside the rotating ring groove 114. When pressed down, the locking heads 111 press against the outer connecting ring 112 and rotate. When the telescopic rod 8 retracts, the pressure ring 11 is pushed back to its original position by the spring force of the spring 113. During the reset, it also rotates at a small angle, thus causing relative rotation between the upper filter plate 7 and the lower filter plate 701. This adjusts the original filtration device to function as a sealing device for the wastewater bottom cavity, thereby cleaning the upper filter plate 7 and removing the cleaned wastewater.

[0040] Please see Figure 1-10 The outer surface of the rotating shaft 501 is fixedly fitted with a retaining ring groove 9. The adjusting retaining teeth 807 are adapted to the retaining ring groove 9. The top of the outer surface of the upper filter plate 7 is provided with a pressing and rotating device 10. The pressing and rotating device 10 includes a pressing ring 11, an anti-rotation rod 12, a retaining head 111, an outer connecting ring 112, a spring 113, and a rotating ring groove 114. Multiple retaining heads 111 are provided on the side of the pressing ring 11 and are embedded in the rotating ring groove 114. When pressed down, the retaining head 111 abuts against the outer connecting ring 112 and rotates. When the telescopic rod 8 retracts, it pushes the pressing ring 11 to reset under the elastic force of the spring 113. When reset, it also rotates at a small angle, thereby enabling the relative rotation of the upper filter plate 7 and the lower filter plate 701. A single power source realizes the connection between the cleaning arm 804 and the rotating shaft 501 and the mode adjustment of the upper filter plate 7 and the filter holes 702.

[0041] Please see Figure 1-10 The anti-rotation rod 12 is fixedly installed inside the outer casing 1. The anti-rotation rod 12 is fixedly connected to the pressure ring 11. The pressure ring 11 is movably sleeved on the outer surface of the rotating shaft 501. The anti-rotation rod 12 is located at the bottom of the cleaning arm 804 to prevent it from getting stuck when rotating. At the same time, it limits the pressure ring 11 to ensure that the pressure ring 11 can only move up and down and cannot rotate.

[0042] Please see Figure 1-10 The outer connecting ring 112 is fixedly installed on one side of the outer surface of the upper filter plate 7. The rotating ring groove 114 is opened on the inner wall of the outer connecting ring 112. The inner wall of the rotating ring groove 114 is set as an asymmetrical groove on the upper and lower sides. When the pressing ring 11 is pressed, it will drive the outer connecting ring 112 to rotate. When the spring 113 returns to the pressing ring 11, it will also drive the rotation of the moving angle.

[0043] Please see Figure 1-10 The clamp head 111 is fixedly installed on the outer surface of the pressure ring 11. The clamp head 111 is movably embedded in the inside of the rotating ring groove 114. The clamp head 111 movably embedded in the inside of the rotating ring groove 114 ensures the stability of the upper filter plate 7 during rotation adjustment.

[0044] Please see Figure 1-10 Spring 113 is fixedly installed on the top of the outer surface of the upper filter plate 7. Spring 113 is movably connected to the pressure ring 11. The output shaft of the first motor 101 is fixedly connected to the connecting seat 603. The connecting seat 603 is movably installed on the top of the outer surface of the heating multilayer tube 5. The heating multilayer tube 5 contains multiple turns of heating wire for heating the catalyst. The heating multilayer tube 5 is embedded with a third motor for connecting to the bottom rotating shaft 501 to prevent the catalyst from getting damp. It can also heat and dehumidify the catalyst that has already gotten damp, thus restoring the decomposition function.

[0045] Please see Figure 1-10A connector 602 is fixedly connected to one side of the outer surface of the connector 603, and a pusher plate 601 is fixedly connected to one end of the outer surface of the connector 602. The pusher plate 601 is slidably embedded inside the storage bin 6. The output shaft of the second motor 102 is fixedly connected to the rotating shaft 103. The device that pushes the catalyst from the storage bin 6 to the stirring position is the pusher plate 601. As the connector 603 rotates, the pusher plate 601 rotates, thereby pushing the catalyst to the stirring and feeding position, thus realizing the stirring before adding the catalyst and the periodic addition.

[0046] Please see Figure 1-10 A connecting cylinder 104 is fixedly installed inside the outer shell 1. A rotating stirring device 105 is movably connected to one end of the outer surface of the connecting cylinder 104. A rotating shaft 103 is movably embedded inside the connecting cylinder 104. The rotating shaft 103 is fixedly connected to the rotating stirring device 105. An intermittent feeding plate 106 is provided on one side of the outer surface of the storage bin 6. The connecting cylinder 104 is fixed inside the outer shell 1 to connect to the fixed gear in the middle position on the side of the rotating stirring device 105. The rotating shaft 103 drives the rotating stirring device 105 to rotate. Two pairs of meshing large and small gears are provided on one side of the rotating stirring device 105. Both small gears are meshed with the fixed gear in the middle position. As the rotating shaft 103 rotates and the middle gear is fixed, the large gears on both sides will be driven to rotate simultaneously, thereby driving the two stirring handles connected to the bottom to stir the catalyst and prevent the catalyst from clumping.

[0047] Working principle

[0048] Since the oxidation tower itself processes wastewater, it is unavoidable that water molecules from the bottom processing stage will permeate into the catalyst. Therefore, a multi-layer heating tube 5 is installed. The multi-layer heating tube 5 contains multiple coils of heating wire to heat the catalyst. A third motor is embedded inside the multi-layer heating tube 5 to connect to the bottom rotating shaft 501. While the output shaft of the second motor 102 drives the stirrer on the rotating stirring device 105 to stir, it can intermittently add catalyst to the bottom catalytic area of ​​the outer shell 1. The catalyst addition pipe is embedded inside the outer shell 1, leading directly to the bottom of the outer shell 1 and close to the ozone addition end of the gasification device 4, which can achieve ozone catalysis more quickly. The specific stirring method is as follows: the rotating shaft 103 drives the second motor 102 to drive the second motor 102 to stir. The rotating shaft 103 drives the rotating stirring device 105 to rotate. The connecting cylinder 104 is fixed inside the outer casing 1 to connect to the fixed gear in the middle of the side of the rotating stirring device 105. Two pairs of meshing gears are provided on one side of the rotating stirring device 105. Both small gears mesh with the fixed gear in the middle. As the rotating shaft 103 rotates, and the middle gear is fixed, the large gears on both sides are simultaneously driven to rotate, which in turn drives the two stirring handles connected to the bottom to stir the catalyst, preventing catalyst clumping. Combined with the heating multi-layer tube 5 on the storage silo 6, this prevents the catalyst from getting damp. For catalysts that have already become damp, heating can be used to dehumidify them, restoring their decomposition function. This also prevents catalyst clumping and ensures the catalyst remains in good condition. The catalytic effect of the catalyst is achieved by rotating the shaft 103 through a fixed gear in the middle and connecting it to the intermittent feeding plate 106 at the bottom. The intermittent feeding plate 106 is double-layered, with the bottom layer fixed and not rotating, while the top layer rotates under the drive of the rotating shaft 103. Both the bottom and top layers have feeding ports. The catalyst will only enter the catalyst pipeline through the feeding port when the rotating top layer is aligned with the bottom layer. The device that pushes the catalyst from the storage bin 6 to the stirring position is the push plate 601. As the connecting seat 603 rotates, the push plate 601 rotates, thereby pushing the catalyst to the stirring and feeding position. This achieves stirring before catalyst addition and periodic addition. At the bottom of the heating multi-layer tube 5, the rotation of the rotating shaft 501 drives the bottom stirring blades 50. 2. The cleaning scraper 503 rotates to fully agitate the internal processing liquid. At the same time, the agitator 502 scrapes away any contaminants that may adhere to the inner wall of the outer casing 1. The top upper filter plate 7 and the lower filter plate 701 serve as the filtration structure when wastewater is added. The upper filter plate 7 can rotate relative to the lower filter plate 701 by pressing. The extension and retraction of the telescopic rod 8 causes the connecting sleeve plate 801 and the independent collar 802 to press down, thereby locking the adjusting tooth 807 into the outside of the retaining ring groove 9. This connects the connecting rod 803, the cleaning arm 804, and the rotating shaft 501. Then, the rotation of the rotating shaft 501 drives the cleaning arm 804 and the cleaning brush head 805 to scrape and clean the upper filter plate 7 after long-term use.To prevent contaminants from falling into the interior of the outer casing 1 after cleaning, a filter hole 702 that can be hidden after rotating a certain angle is provided, blocking the sewage's path. A water pump is installed at the liquid inlet pipe 2 to extract the cleaned sewage from the top of the upper filter plate 7. The rotation of the upper filter plate 7 is also driven by the telescopic rod 8. The extension and retraction of the telescopic rod 8 causes the adjusting teeth 807 to press down, which in turn presses down against the pressure ring 11. The side of the pressure ring 11 has multiple locking heads 111 that are embedded inside the rotating ring groove 114. When pressed down, the locking heads 111 press against the outer connecting ring 112 and rotate. When the telescopic rod 8 retracts, the spring force of the spring 113 pushes the pressure ring 11 back to its original position. During the return to its original position, it also rotates at a small angle, thereby causing the relative rotation of the upper filter plate 7 and the lower filter plate 701. This adjusts the original filtration device to a sealing device that can act as a sewage bottom cavity, thus achieving the cleaning of the upper filter plate 7 and the extraction of the cleaned sewage.
