A waste valve pipe 18 is connected to the filter cylinder 3, and a clean water drainage pipe 19 is connected to one side of the bottom of the filter cylinder body 1, that is, sewage flows into the filter cylinder 3, is filtered by the filter cylinder 3, impurities remain inside the filter cylinder 3, and clean water is discharged. This equipment needs to filter fine particles and cannot filter sewage with larger garbage. A first electrically controlled valve 20 is connected to the sewage inlet pipe 17, and a second electrically controlled valve 21 is connected to the clean water drainage pipe 19. When internal cleaning is performed, the first electrically controlled valve 20 and the second electrically controlled valve 21 are closed to reduce sewage input and clean water discharge.

[0021] In specific implementation: sewage flows into the filter cylinder 3 through the sewage inlet pipe 17, is filtered by the filter cylinder 3, impurities remain inside the filter cylinder 3, and clean water is discharged. Then, when cleaning, it is necessary to open the waste valve pipe 18 to discharge impurities and flushing water together.

The filter cartridge body 1 is provided with a second adjusting screw 5 which is rotatably connected in the middle of the filter screen cylinder member 3. A lifting block 6 is threadedly connected on the first adjusting screw 4. The lifting blocks 6 on both sides are jointly connected with a water distribution ring pipe 7 which is sleeved with the filter screen cylinder member 3. The inner side of the water distribution ring pipe 7 is connected with a plurality of sprayers 8 which are aligned with the filter screen cylinder member 3. The lifting operation of the water distribution ring pipe 7 and the sprayer 8 can be driven by the rotation of the second adjusting screws 5 on both sides and the lifting blocks 6 on both sides. A water pump 9 is connected to the top of the filter cartridge body 1, and the water pump 9 is connected to a water suction pipe 10 and a water outlet pipe 11 extending to the top of the filter cartridge body 1. A water hose 12 is connected to the bottom of the water outlet pipe 11. The water hose 12 is a shrinkable type, so that it can cooperate with the lifting and lowering operations of the water distribution ring pipe 7 and the sprayer 8. The bottom of the water hose 12 is connected to a water pipe 13 connected to the water distribution ring pipe 7. Clean water is extracted from the outside by the water pump 9. During the lifting and lowering process of the water distribution ring pipe 7, the filter screen cylinder 3 can be sprayed and flushed from the outside to the inside through the sprayer 8.

[0023] During the specific implementation: by rotating the second adjusting screws 5 on both sides and through the threaded lifting blocks 6, the water distribution ring pipe 7 and the sprayer 8 can be driven to rise and fall, the water pump 9 is started to extract clean water, and the water is input to the water distribution ring pipe 7 through the water suction pipe 10, the water outlet pipe 11, the water supply hose 12 and the water guide pipe 13, and then the multiple sprayers 8 can spray and flush the filter screen cylinder 3 from the outside to the inside.

[0024] Combined with Figure 3-5 The second adjusting screw 5 is threadedly connected with an inner circular scraper 14, and the rotation of the second adjusting screw 5 can drive the inner circular scraper 14 to perform internal material hanging operations on the filter cylinder 3. The top plate of the filter cylinder body 1 is connected with a driving motor 22 and a transmission box 23 that drive the first adjusting screw 4 and the second adjusting screw 5 to rotate. The power end of the driving motor 22 is directly connected to the second adjusting screw 5. The first adjusting screw 4 and the second adjusting screw 5 extend into the transmission box 23 and are connected with a sprocket chain transmission group 24, that is, the second adjusting screw 4 and the second adjusting screw 5 are driven by the driving motor 22. The adjusting screw 5 rotates, and then cooperates with the sprocket chain transmission group 24 to synchronously drive the rotation operation of the first adjusting screws 4 on both sides. A support plate 15 is connected to the bottom of the inner side of the filter mesh cylinder 3 in the filter cartridge body 1. The support plate 15 supports the rotation setting of the second adjusting screw 5. The inner top plate of the filter cartridge body 1 and the top of the support plate 15 are jointly connected with a plurality of limiting sleeves 16 that penetrate the inner circular scraper 14. The limiting sleeves 16 can prevent the inner circular scraper 14 from rotating with the second adjusting screw 5, thereby ensuring the stable lifting and lowering operation of the inner circular scraper 14.

[0025] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
