Two annular grooves 4 are symmetrically provided at one end of the input pipe 3, and an annular slider 5 is slidably installed in the annular groove 4, and a filter cartridge 6 is fixedly connected between the annular sliders 5. A protective cover 7 is installed on the outer wall of the bottom end of the input pipe 3, and a driving motor 8 is installed in the protective cover 7. A rotating shaft 9 is installed at the output end of the driving motor 8, and one end of the rotating shaft 9 rotates through the input pipe 3 and extends to the inside thereof, and a driving bevel gear 10 is installed therein, and a driven bevel gear 11 is installed at the center of one side of the annular slider 5 through a rotating shaft, and the driving bevel gear 10 and the driven bevel gear 11 are meshed with each other;

[0024] A discharge port 24 is provided on the outer wall of the bottom side of the water inlet end of the input pipe 3, and a movable door 25 is installed on the bottom side of the input pipe 3 at one side of the discharge port 24 through a hinge;

[0025] The interior of the filter cartridge 6 is in a truncated cone shape, and the filter cartridge 6 is made of stainless steel. The active bevel gear 10 and the driven bevel gear 11 are both made of titanium alloy. When working, in actual applications, sewage often contains various suspended matter and sediments. If it is not treated, the slurry in the sewage will directly enter the pump 1, causing a large amount of slurry to accumulate inside the pump 1, which in turn causes the pump 1 to be blocked, reducing the service life of the pump 1. When sewage flows in from the water inlet end of the input pipe 3, the slurry is filtered by the filter cartridge 6 and remains inside it, while the clean liquid flows into the water inlet of the pump 1 through the filter cartridge 6 and is finally discharged through the output pipe 2. At the same time, the drive motor 8 is started to drive the rotating shaft 9 to rotate, thereby rotating the active bevel gear 10, so that the driven bevel gear 11 drives the annular sliding The block 5 rotates in the annular groove 4, thereby driving the rotation of the filter cartridge 6, effectively reducing the retention of impurities in a fixed area, reducing the possibility of clogging, and ensuring smooth water flow. At the same time, during the rotation of the filter cartridge 6, the slurry attached to the inner wall of the filter cartridge 6 will gradually slide to the vicinity of the discharge port 24 due to the action of centrifugal force and gravity. When cleaning is required, the movable door 25 is opened, and the slurry can be discharged through the discharge port 24 to achieve the discharge of the slurry. After the slag is discharged, the movable door 25 is closed and the next cleaning process is waited for, which effectively prevents the slurry from entering the pump 1, thereby avoiding clogging of the pump. The filter cartridge 6 is made of stainless steel and has a smooth surface, which is convenient for the slurry to slide out of the filter cartridge. The active bevel gear 10 and the driven bevel gear 11 are made of titanium alloy and are not easy to rust.

[0026] See also Figure 1-5As shown, a delivery pipe 12 is installed on the outer wall of the top side of the input pipe 3, and three nozzles 13 are equidistantly installed on the outer wall of the delivery pipe 12. One end of the delivery pipe 12 is connected to a connecting pipe 14, and the bottom side of the connecting pipe 14 is connected to a water inlet pipe 15. One end of the water inlet pipe 15 extends into the input pipe 3 and is located on one side of the filter cartridge 6. A hollow block 16 is installed inside the water inlet pipe 15, and a spring 17 is fixedly connected to the top side of the hollow block 16. A blocking block 18 is connected to the top side of the spring 17. A rod barrel 19 is connected through one end of the connecting pipe 14, and a piston 20 is slidably installed inside the rod barrel 19. A connecting rod 21 is fixedly connected to one side of the piston 20, and a connecting plate 22 is fixedly connected to one side of the connecting rod 21. A telescopic rod 23 is installed on the outer wall of the input pipe 3, and the active end of the telescopic rod 23 is fixedly installed on one side edge of the connecting plate 22. During operation, as time goes by, the slag in the sewage The slurry will gradually accumulate on the filter cartridge 6, which will block the pores of the filter cartridge 6 and cause the filtration efficiency to decrease. When the filter cartridge 6 needs to be rinsed, the telescopic rod 23 is extended to push the connecting plate 22 to move away from the delivery pipe 12, so that the connecting rod 21 drives the piston 20 to slide in the rod barrel 19, forming a negative pressure, and part of the water in the input pipe 3 is sucked into the rod barrel 19 by the water inlet pipe 15. At the same time, the spring 17 is stretched, the block 18 moves upward, and the inlet of the water inlet pipe 15 is opened. When water spraying is required, the telescopic rod 23 works in the reverse direction to make the piston 20 slide in the rod barrel 19 in the reverse direction, and the water in the rod barrel 19 flows into the delivery pipe 12 through the connecting pipe 14, and the water is sprayed to the filter cartridge 6 by the nozzle 13 to rinse the filter cartridge 6 and remove the slurry attached to the filter cartridge 6. At the same time, the spring 17 is compressed, the block 18 closes the inlet of the water inlet pipe 15, and when rinsing, the filter cartridge 6 rotates, and the water can rinse the surface of the filter cartridge 6 more evenly, thereby improving the rinsing effect and achieving the cleaning of the slurry.

[0027] Working principle: when sewage flows in from the water inlet end of the input pipe 3, the slurry is filtered by the filter cartridge 6 and remains inside it, while the clean liquid flows into the water inlet of the pump 1 through the filter cartridge 6 and is finally discharged through the output pipe 2. At the same time, the driving motor 8 is started to drive the rotating shaft 9 to rotate, thereby rotating the active bevel gear 10, so that the driven bevel gear 11 drives the annular slider 5 to rotate in the annular groove 4, thereby driving the rotation of the filter cartridge 6, effectively reducing the retention of impurities in a certain fixed area, reducing the possibility of blockage, and ensuring smooth water flow. At the same time, during the rotation of the filter cartridge 6, the slurry attached to the inner wall of the filter cartridge 6 will gradually slide to the vicinity of the discharge port 24 due to the action of centrifugal force and gravity. When cleaning is required, the movable door 25 is opened, and the slurry can be discharged through the discharge port 24 to realize the discharge of the slurry. After the slag discharge is completed, the movable door 25 is closed to wait for the next cleaning process, thereby effectively preventing the slurry from entering the pump 1, thereby avoiding the blockage of the pump.

[0028] When the filter cartridge 6 needs to be rinsed, the telescopic rod 23 extends, pushing the connecting plate 22 to move away from the delivery pipe 12, so that the connecting rod 21 drives the piston 20 to slide in the rod barrel 19, forming a negative pressure, and part of the water in the input pipe 3 is sucked into the rod barrel 19 by the water inlet pipe 15. At the same time, the spring 17 is stretched, the block 18 moves upward, and the inlet of the water inlet pipe 15 is opened. When water spraying is required, the telescopic rod 23 works in the reverse direction, causing the piston 20 to slide in the rod barrel 19 in the reverse direction, and the water in the rod barrel 19 flows into the delivery pipe 12 through the connecting pipe 14, and the water is sprayed toward the filter cartridge 6 by the nozzle 13 to rinse the filter cartridge 6 and remove the slurry attached to the filter cartridge 6. At the same time, the spring 17 is compressed, the block 18 closes the inlet of the water inlet pipe 15, and when rinsing, the filter cartridge 6 rotates, and the water can rinse the surface of the filter cartridge 6 more evenly, thereby improving the rinsing effect and achieving the cleaning of the slurry.
