Description

Technical Field

[0001] The invention relates to the technical field of water filtration, and in particular to a fish pond drum filter with an automatic filter cotton cleaning structure. Background Art

[0002] The fish pond drum machine is a high-efficiency water treatment equipment used in aquaculture. It is mainly used to remove solid waste and other suspended particles in the water. Its working principle is to perform preliminary filtration through a cylindrical filter. When the water flows through the cylindrical filter, the solid waste is trapped inside the filter, and the clean water flows through the cylindrical filter. The water after preliminary filtration is then deeply filtered by the filter cotton to filter the fine suspended particles inside. The filtered water is then returned to the fish pond. This cycle keeps the water in the fish pond clean. However, due to the long-term use of the filter cotton, After that, tiny impurities will block the filter cotton and reduce the flow rate of water passing through the filter cotton, resulting in the inability to deeply filter the water in the fish pond and unable to flow back into the fish pond, thereby affecting the cleanliness of the water in the fish pond. Therefore, the user is required to regularly clean or replace the filter cotton to maintain the normal operation of the drum machine. However, when replacing the filter cotton in the existing drum machine, the drum machine needs to be shut down. At this time, the drum machine will also stop filtering the water in the fish pond until the filter cotton is successfully replaced.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0021] After long-term use, tiny impurities will block the filter cotton, reducing the flow of water through the filter cotton, resulting in the inability to deeply filter the water in the fish pond and unable to flow back into the fish pond, thereby affecting the cleanliness of the water in the fish pond. Therefore, users are required to clean or replace the filter cotton regularly to maintain the normal operation of the drum machine. When users replace the filter cotton, they need to shut down the drum machine, and the drum machine will also stop filtering the water in the fish pond until the filter cotton is successfully replaced, which greatly reduces the filtration efficiency of the water in the fish pond.

The first turntable 6 is truncated, and the end with a small diameter is located on the left side. The left side of the shell 1 is rotatably connected to a rotating shaft, and the rotating shaft is fixedly connected to a gear 7 meshing with the gear ring 4. The gear 7 is provided with a first turntable 8, and the first turntable 8 is fitted with the first turntable 6, so that the output shaft of the first motor 5 passes through the first turntable 6, the first turntable 8, the gear 7 and The gear ring 4 drives the filter cartridge 3 to rotate, so that the filter cartridge 3 evenly filters the impurities in the water in the fish pond. The right side of the outer shell 1 is fixedly connected and connected with a T-shaped tube 9. Two mirror-distributed cavities are arranged in the circulation shell 2. The two mirror-distributed cavities are both connected with the T-shaped tube 9. The circulation shell 2 is slidably connected with two mirror-distributed filter cottons 10. The filter cottons 10 are used to further filter the impurities in the water in the fish pond. The two mirror-distributed filter cottons 10 are respectively located in the middle of adjacent cavities. The circulation shell 2 is fixedly connected with two mirror-distributed detection tubes 11. The two ends of the detection tube 11 are respectively sealed and slidably connected with a float 12 and a switching rod 13. The float 12 is located in the circulation shell. 2, when the filter cotton 10 is blocked by impurities and cannot be filtered, the water accumulated above the filter cotton 10 drives the float 12 to move upward along the adjacent detection tube 11. A three-way valve is arranged at the intersection of the T-shaped tube 9. The three-way valve is provided with a position detection device to detect its open state. The three-way valve is used to allow the water in the housing 1 to enter the two cavities of the circulation shell 2 respectively under different states. The two mirror-distributed switching rods 13 are squeezed and matched with the valve stem of the three-way valve. The float 12 moves upward along the adjacent detection tube 11 to squeeze the gas in the adjacent detection tube 11, so that the gas pushes the adjacent switching rod 13 to squeeze the three-way valve. The valve stem of the three-way valve is used to switch the operating state of the three-way valve. The left side of the shell 1 is fixedly connected with a water inlet pipe connected with the filter cartridge 3, which is used to inject water in the fish pond into the filter cartridge 3. The bottoms of the two cavities of the circulation shell 2 are fixedly connected and connected with a reflux pipe, which is used to return the filtered water to the fish pond. A recoil assembly for recoil filter cartridge 3 is arranged in the shell 1, and a transport and cleaning assembly for cleaning the filter cotton 10 is arranged in the circulation shell 2. By detecting the blocking state of the filter cotton 10, the two filter cottons 10 are switched to operate autonomously, and the filter cotton 10 is replaced without stopping the machine, thereby avoiding stopping the machine to replace the filter cotton 10, wasting a lot of time, and reducing the filtering efficiency of the water in the fish pond.

[0023] like Figure 2 and Figure 6As shown, the recoil assembly includes a recoil pipe 202, which is fixedly connected to the inside of the shell 1, and the bottom end of the recoil pipe 202 is fixedly connected and connected to a water pump 201, and the other end of the recoil pipe 202 is fixedly connected and connected to a recoil head 203 in a linear array. The water pump 201 extracts clean water in the shell 1 and sprays it to the filter cartridge 3 through the recoil head 203 to backwash the filter cartridge 3. A drain pipe 204 is fixedly connected to the right side of the shell 1, and the drain pipe 204 is fixedly connected and connected to a collecting shell 205. The collecting shell 205 is located inside the filter cartridge 3 and directly below the recoil head 203 in a linear array, so that the water sprayed by the recoil head 203 and infiltrated into the filter cartridge 3 carries impurities and directly falls into the collecting shell 205 and is discharged along the drain pipe 204.

[0024] like Figure 1 , Figure 4 and Figure 7 As shown, the transfer and cleaning component includes two first push rods 301 distributed symmetrically with respect to the center, the mirror-distributed first push rods 301 are fixedly connected to the middle part of the circulation shell 2, the telescopic ends of the two mirror-distributed first push rods 301 are fixedly connected to the adjacent filter cotton 10, the circulation shell 2 is fixedly connected with a mirror-distributed drain pipe 302, the two mirror-distributed drain pipes 302 are respectively connected to the adjacent cavities of the circulation shell 2, the drain pipe 302 is located above the adjacent filter cotton 10, and a solenoid valve is provided on the drain pipe 302 for discharging the water accumulated in the cavity of the circulation shell 2, the outside of the circulation shell 2 is fixedly connected with two cleaning tables 303 distributed in front and behind mirror images, the cleaning tables 303 are slidably connected to the adjacent filter cotton 10, the bottom of the cleaning table 303 is fixedly connected and connected with a sewage outlet pipe 304, the sewage outlet pipe 304 is used to discharge the sewage generated by cleaning the filter cotton 10, and the outside of the circulation shell 2 is provided with a cleaning component for cleaning all the filter cottons 10.

[0025] like Figure 7-Figure 9As shown, the cleaning component includes two second push rods 305 with front and rear mirror image distribution, the two second push rods 305 with front and rear mirror image distribution are fixedly connected to the side wall of the circulation shell 2, the telescopic end of the second push rod 305 is slidably connected with a sliding plate 306, the outside of the circulation shell 2 is fixedly connected with four fixed plates 307 with mirror image distribution, and a slide groove 308 is arranged on the fixed plate 307, the slide groove 308 is composed of a linear array of W-shaped grooves connected end to end, the W-shaped groove is composed of four mirror image distributed inclined grooves and two mirror image distributed transverse grooves, the transverse groove is located between two adjacent inclined grooves, and is connected end to end, the slide groove 308 is slidably connected to the adjacent sliding plate 306, and the sliding plate 306 is slidably connected to the cleaning Plate 309, the cleaning plate 309 is in contact with the adjacent filter cotton 10, the telescopic end of the second push rod 305 drives the cleaning plate 309 to clean the impurities on the adjacent filter cotton 10 through the adjacent sliding plate 306 and the adjacent fixed plate 307, and the fixed plate 307 drives the cleaning plate 309 to periodically push the impurities on the adjacent filter cotton 10 through the adjacent slide groove 308, a linear array of first elastic elements 310 is arranged between the sliding plate 306 and the adjacent cleaning plate 309, the first elastic element 310 is a spring, which is used to drive the cleaning plate 309 to apply a certain pressure to the adjacent filter cotton 10, the sliding plate 306 is fixedly connected with a water injection nozzle 311, and the water injection nozzle 311 is connected to an external water injection device.

[0026] When it is necessary to filter the water in the fish pond, the staff injects the water in the fish pond into the filter cartridge 3 through the water inlet pipe on the left side, and the water enters the outer shell 1 through the filter cartridge 3. At the same time, the impurities in the water are filtered into the inside of the filter cartridge 3, and then the first motor 5 is turned on. The output shaft of the first motor 5 drives the first turntable 6 thereon to rotate, so that the first turntable 6 drives the first turntable 8 to rotate, and the first turntable 8 drives the gear 7 to rotate synchronously through the rotating shaft, and the gear 7 drives the filter cartridge 3 to rotate synchronously through the gear ring 4, so as to change the position of the water filtered by the filter cartridge 3 to prevent impurities from adhering to one side of the inside of the filter cartridge 3. At the same time, the water pump 201 is turned on, and the water pump 201 extracts the clean water after filtering from the outer shell 1, so that the clean water flows upward along the recoil pipe 202, and then is discharged along the recoil head 203 of the linear array, and is discharged by the recoil head 203. The discharged water impacts the top of the filter cartridge 3. Since the filter cartridge 3 is in a rotating state, the backwash head 203 evenly backwashes the filter cartridge 3. Since the collecting shell 205 is located inside the filter cartridge 3 and below the backwash head 203 in the linear array, the impurities attached to the inside of the filter cartridge 3 are impacted and fall into the collecting shell 205. Then the water flow carries the impurities along the collecting shell 205 and flows into the sewage pipe 204. The impurities are discharged to the outside along the sewage pipe 204. At the same time, the clean water in the outer shell 1 enters the T-shaped pipe 9. At this time, the three-way valve on the T-shaped pipe 9 opens the water outlet end on the front side. At this time, the clean water enters the cavity on the front side of the circulation shell 2 along the T-shaped pipe 9. After entering the cavity on the front side, the clean water is further filtered by the front filter cotton 10, and then the water flows back to the fish pond along the reflux pipe at the bottom.

[0027] After the clean water is filtered by the filter cotton 10, the impurities in the clean water will adhere to the outside of the filter cotton 10, gradually blocking the flow of clean water on the filter cotton 10. At this time, the clean water will gradually accumulate above the filter cotton 10 and cannot continue to flow downward. The water accumulated above the filter cotton 10 gradually drives the adjacent float 12 to move upward. The upward movement of the float 12 pushes the gas in the adjacent detection tube 11, so that the gas in the detection tube 11 pushes the adjacent switching rod 13, and the switching rod 13 pushes the valve stem of the three-way valve, so that the three-way valve switches to the Water is injected into the rear cavity of the circulation shell 2, and then the clean water in the outer shell 1 flows along the T-tube 9 into the rear cavity of the circulation shell 2. At this time, the position detection device on the three-way valve detects the switching of the open state. At this time, the solenoid valve of the drain pipe 302 on the front side is opened to discharge the water accumulated in the front cavity of the circulation shell 2. By detecting the blocking state of the filter cotton 10, the two filter cottons 10 can switch to operate autonomously, and the filter cotton 10 can be replaced without stopping the machine, which saves the replacement time of the filter cotton 10 and improves the filtering efficiency of the water in the fish pond.

[0028] After the water accumulated in the front cavity of the circulation shell 2 is completely drained, the first push rod 301 on the front side is opened, and the telescopic end of the first push rod 301 drives the adjacent filter cotton 10 to slide outward. After the telescopic end of the first push rod 301 drives the adjacent filter cotton 10 to completely slide to the adjacent cleaning station 303, the second push rod 305 on the front side is opened, and the external water injection device is opened at the same time. The water injection device injects cleaning water into the water injection nozzle 311, so that the water injection nozzle 311 impacts and cleans the impurities outside the adjacent filter cotton 10. At the same time, the second push rod 305 on the front side is opened. The telescopic end of the second push rod 305 drives the sliding plate 306 thereon to move forward synchronously, and the sliding plate 306 moves forward and slides along the inclined groove of the W-shaped groove on the slide groove 308. At this time, the sliding plate 306 slides downward and drives the cleaning plate 309 at the bottom thereof to move synchronously, so that the cleaning plate 309 contacts the adjacent filter cotton 10, and then the sliding plate 306 continues to slide downward. At this time, the first elastic element 310 of the linear array is compressed, so that the cleaning plate 309 applies a certain pressure to the adjacent filter cotton 10, and this is carried out until the sliding plate 306 slides to the W-shaped groove on the slide groove 308. The cleaning plate 309 maintains pressure and pushes the impurities outside the adjacent filter cotton 10 along the transverse groove of the W-shaped groove until the sliding plate 306 slides to the lower inclined groove of the W-shaped groove on the slide groove 308. At this time, the sliding plate 306 moves upward, so that the first elastic element 310 of the linear array is reset, and the cleaning plate 309 is separated from the adjacent filter cotton 10, so that the water sprayed by the water injection nozzle 311 impacts the impurities under cleaning. After the telescopic end of the first push rod 301 drives the adjacent filter cotton 10 to completely slide to the adjacent cleaning table 303, the first push rod 301 is used to push the adjacent filter cotton 10 to the adjacent cleaning table 303. The telescopic end of a push rod 301 drives the adjacent filter cotton 10 to perform a short-distance linear reciprocating motion to avoid blind spots in the cleaning of the adjacent filter cotton 10 by the cleaning plate 309. This cycle is repeated until the sliding plate 306 slides to the limit position of the adjacent slide groove 308, and then the second push rod 305 drives the adjacent sliding plate 306 to slide back to the initial position. After five to ten cycles, the second push rod 305 is closed. At this time, the cleaning of the front filter cotton 10 is completed, and the cleaned sewage is discharged to the outside along the sewage outlet pipe 304 at the bottom of the cleaning table 303.

[0029] After the front filter cotton 10 is cleaned, the external water injection device is closed and the operation of the second push rod 305 is stopped. At this time, the telescopic end of the first push rod 301 stops the linear reciprocating motion and drives the front filter cotton 10 to reset. Then the first push rod 301 and the solenoid valve in the front drain pipe 302 are closed. When the filter cotton 10 in the rear cavity is also blocked by impurities, the above steps are repeated. The water in the fish pond is continuously filtered in this cycle. When the filtering of the water in the fish pond stops, the water in the fish pond is stopped from being injected into the filter cartridge 3. Then the first motor 5 and the water pump 201 are turned off. When the water in the fish pond needs to be filtered again, the above steps are repeated.

[0030] In this embodiment, the connection between the first turntable 8 and the rotating shaft is a fixed connection, but it is limited to embodiment 1. In other subsequent embodiments, the connection between the first turntable 8 and the rotating shaft is a spline connection. Please refer to the specific description in the subsequent embodiments.

[0031] Embodiment 2: Based on embodiment 1, Fig.10 As shown, it also includes a limiting component for preventing the water sprayed by the recoil heads 203 of the linear array from splashing. The limiting component is arranged on the recoil heads 203 of the linear array. The limiting component includes a fitting shell 401. The fitting shell 401 is fixedly connected to the recoil heads 203 of the linear array. A blocking airbag 402 is fixedly connected to the interior of the fitting shell 401. The recoil heads 203 of the linear array are all located inside the blocking airbag 402. The blocking airbag 402 is fitted with the filter cartridge 3 to enable the blocking airbag 402 to enclose and limit the water discharged by the recoil heads 203, so that the water can penetrate into the filter cartridge 3 for backwashing, thereby preventing the water discharged by the recoil heads 203 from splashing to the outside, resulting in a large amount of water being unable to backwash the filter cartridge 3. An expansion component for adjusting the degree of fit between the blocking airbag 402 and the filter cartridge 3 is arranged on the recoil pipe 202.

[0032] like Figure 6 and Fig.10 As shown, the expansion component includes two first connecting tubes 403 with mirror-image distribution, the first connecting tubes 403 are fixedly connected and connected to the recoil pipe 202, the recoil pipe 202 is fixedly connected with two first fixed cylinders 404 with mirror-image distribution, a piston plate 405 is sealingly and slidably connected inside the first fixed cylinder 404, the piston plate 405 divides the first fixed cylinder 404 into two cavities, the upper cavity is connected to the first connecting tube 403, the interior is the water in the shell 1 extracted by the water pump 201, a second connecting tube 406 is fixedly connected between the first fixed cylinder 404 and the blocking airbag 402, the lower cavity is connected to the second connecting tube 406, a scraping component for scraping impurities inside the filter cartridge 3 is provided on the shell 1, the fitting strength of the blocking airbag 402 and the filter cartridge 3 is autonomously adjusted according to the blocking degree of the filter cartridge 3, to avoid leakage of water in the blocking airbag 402 due to the increase of water pressure in the blocking airbag 402.

[0033] like Fig.11 and Fig.12As shown, the scraping assembly includes a second motor 501, the second motor 501 is fixedly connected to the left side of the housing 1, the output shaft of the second motor 501 is fixedly connected to the second turntable 502, the second turntable 502 is truncated, and the end with a smaller diameter is located on the right side, the left side of the housing 1 is rotatably connected to a rotating member 503, the rotating member 503 is spline-connected to a second turntable 504 located outside the housing 1, the second turntable 504 is fitted with the second turntable 502, the output shaft of the second motor 501 drives the rotating member 503 to rotate through the second turntable 502 and the second turntable 504, and the left side of the housing 1 is slidably connected to the rotating member 503. There is a sliding frame 505, which is slidably connected to the rotating member 503. The rotation of the rotating member 503 drives the sliding frame 505 to perform linear reciprocating motion along the outer shell 1. The sliding frame 505 is fixedly connected with a flexible scraper 506 that fits the filter cartridge 3. The flexible scraper 506 is used to fit the curved surface of the filter cartridge 3. An adjusting component for adjusting the rotation speed of the filter cartridge 3 is provided on the recoil pipe 202. The top of the filter cartridge 3 is scraped back and forth by the flexible scraper 506 to scrape off impurities attached to the inside of the filter cartridge 3, thereby reducing the blockage of the filter cartridge 3 by impurities and increasing the recoil rate of the filter cartridge 3 by the external recoil head 203.

[0034] like Figure 1 and Fig.13 As shown, the regulating assembly includes a third connecting pipe 601, the third connecting pipe 601 is fixedly connected and connected to the recoil pipe 202, the left side of the housing 1 is fixedly connected with a second fixed cylinder 602 fixedly connected to the third connecting pipe 601, the second fixed cylinder 602 is sealingly and slidably connected with a piston shaft 603, and the two cooperate to form a closed cavity, which is communicated with the third connecting pipe 601, and the inside is the water in the housing 1 extracted by the water pump 201, the piston shaft 603 is fixedly connected with a pushing frame 604, and a second elastic element 605 is arranged between the piston shaft 603 and the second fixed cylinder 602, the second elastic element 605 is a spring, and the second elastic element 605 is used to drive the adjacent piston shaft 603 to reset, the first turntable 8 and the second turntable 50 4 are rotatably connected to the push frame 604, and the first turntable 8 is splined with the rotating shaft. When the blocking degree of the filter cartridge 3 is high, the flow rate of water in the blocking airbag 402 entering the filter cartridge 3 is reduced. At this time, the water pressure in the blocking airbag 402 increases, thereby pushing the piston shaft 603 to slide along the fixed cylinder 602, so that the piston shaft 603 drives the push frame 604 to slide, thereby reducing the transmission ratio of the first turntable 8 to the first turntable 6 and increasing the transmission ratio of the second turntable 502 to the second turntable 504, thereby increasing the scraping speed of the flexible scraper 506 for impurities inside the filter cartridge 3, reducing the blocking degree of impurities in the filter cartridge 3, and at the same time reducing the rotation speed of the filter cartridge 3, extending the recoil time of the linear array recoil head 203 on the filter cartridge 3, and improving the recoil effect of the recoil head 203 on the filter cartridge 3.

[0035] When the water pump 201 draws clean water from the shell 1 into the recoil pipe 202 and discharges it along the recoil head 203 in the linear array to recoil the filter cartridge 3, part of the water will splash to the outside after contacting the filter cartridge 3, resulting in a large amount of water being unable to recoil the filter cartridge 3, but will flow along the outside of the filter cartridge 3 and eventually flow back into the shell 1 again, reducing the recoil rate of the recoil head 203 on the filter cartridge 3. When the water is discharged along the recoil head 203 in the linear array, it will enter the blocking airbag 402. Since the blocking airbag 402 fits the filter cartridge 3, the water discharged by the recoil head 203 is limited, so that the water cannot flow downward along the filter cartridge 3 into the shell 1, thereby increasing the amount of water recoiled on the filter cartridge 3 and improving the recoil rate of the filter cartridge 3.

[0036] When the filter cartridge 3 starts to filter, the second motor 501 is turned on, and the output shaft of the second motor 501 drives the second turntable 502 to rotate, and the second turntable 502 drives the second turntable 504 to rotate, and the second turntable 504 drives the rotating member 503 to rotate synchronously, and the rotating member 503 rotates to drive the sliding frame 505 to slide forward and backward along the outer shell 1, and the sliding frame 505 drives the flexible scraper 506 to slide forward and backward synchronously, so that the flexible scraper 506 reciprocates and scrapes the top of the filter cartridge 3 to scrape off the impurities attached to the inside of the filter cartridge 3, reduce the blockage of the filter cartridge 3 by impurities, and increase the recoil rate of the filter cartridge 3 by the external recoil head 203. At this time, the water recoiled by the top of the filter cartridge 3 flows downward, and the impurities pushed by the flexible scraper 506 are uniformly carried to the collecting shell 205 below, and finally discharged to the outside along the sewage pipe 204, until the water in the fish pond is stopped from being filtered. At this time, the second motor 501 is turned off, and when the water in the fish pond needs to be filtered again, the above steps are repeated.

[0037] When there are too many impurities attached to the inner wall of the filter cartridge 3, the flow rate of water in the blocking airbag 402 entering the filter cartridge 3 will be reduced. Since the extraction power of the water pump 201 remains unchanged, the water pressure in the blocking airbag 402 begins to increase, causing the water pressure in the recoil pipe 202 to increase synchronously. At this time, the water in the recoil pipe 202 flows along the third connecting pipe 601 and finally enters the second fixed cylinder 602. Then, the water in the second fixed cylinder 602 pushes the piston shaft 603 to slide to the left, causing the piston shaft 603 to drive the driving frame 604 to move to the left. At the same time, the second elastic element 605 is compressed, and the driving frame 604 drives the first turntable 8 to slide to the left, changing the first turntable 8 and the first turntable 8. The fitting position of the first turntable 6 is changed, the transmission ratio of the first turntable 6 to the first turntable 8 is reduced, and then the rotation speed of the gear 7 is reduced, so that the rotation speed of the filter cartridge 3 is slowed down, the recoil time of the linear array recoil head 203 on the filter cartridge 3 is extended, and the recoil effect of the recoil head 203 on the filter cartridge 3 is improved. At the same time, the push frame 604 pushes the second turntable 504 to move left synchronously, the fitting position of the second turntable 504 and the second turntable 502 is changed, and the transmission ratio of the second turntable 502 to the second turntable 504 is increased, so that the rate at which the flexible scraper 506 scrapes away impurities on the top of the inner wall of the filter cartridge 3 is increased, the attachment content of impurities on the inner wall of the filter cartridge 3 is reduced, and the recoil rate of the filter cartridge 3 by the recoil head 203 is increased.

[0038] At the same time, when the water pressure in the blocking airbag 402 begins to increase, the water pressure in the recoil pipe 202 increases synchronously, causing the water in the recoil pipe 202 to enter the two first fixed cylinders 404 along the two first connecting pipes 403 distributed in a mirror image, respectively. At this time, the water in the first fixed cylinder 404 pushes the adjacent piston plates 405, causing the two piston plates 405 to move downward, and the piston plates 405 push the gas in the first fixed cylinder 404 along the adjacent second connecting pipe 406 into the blocking airbag 402. After the gas enters the blocking airbag 402, the blocking airbag 402 is further expanded, increasing the fit between the blocking airbag 402 and the filter cartridge 3, thereby avoiding leakage of water in the blocking airbag 402 due to the increase in water pressure in the blocking airbag 402.

[0039] This continues until the impurities attached to the inner wall of the filter cartridge 3 are gradually reduced. At this time, the flow rate of the filter cartridge 3 gradually increases, the water in the blocking airbag 402 begins to seep into the filter cartridge 3, and the water between the blocking airbag 402 and the filter cartridge 3 begins to gradually decrease. At this time, the water pressure in the backwash pipe 202 gradually decreases, causing the two mirror-distributed piston plates 405 to reset. At this time, the volume of the gas in the blocking airbag 402 returns to its initial state, and at the same time, the second elastic element 605 is reset and drives the adjacent piston shaft 603 to reset. The piston shaft 603 drives the first turntable 8 and the second turntable 504 to reset through the push frame 604. When the impurities inside the filter cartridge 3 increase again, repeat the above steps.
