[0061] The driving motor 12 cooperates with the rotating shaft 2 to drive the auger rod 41 and the outer gear ring 73 to rotate and change the working height of the inner shell 9 below the isolation sleeve 3.

[0062] The top cover 11 and the water inlet pipe 13 cooperate to discharge the wastewater from the down recycling process into the tank body 1. The wastewater needs to immerse the filter sleeve 7 and the water level of the wastewater does not exceed the tank body 1 to enter the top cover 11.

[0069] The cooperation between the water guide hole 32 and the one-way valve 34 facilitates the cooperation between the one-way valve 34 and the water guide pipe 62 when the water pressure between the filter sleeve 7 and the cover shell 8 increases, and guides water to the outside of the scraper 61 and the outside of the filter sleeve 7 through the guide frame 63, thereby flushing impurities on the outside of the filter sleeve 7 and the scraper 61 into the guide seat 33.

[0070] The guide seat 33 cooperates with the auger rod 41 to introduce impurities into the feed portion of the auger tube 4 .

[0071] In this embodiment, the top discharge port of the auger tube 4 extends to the outside of the tank body 1, and the middle of the auger tube 4 is movably connected with an auger rod 41. An internal spline hole is fixedly provided from the top to the bottom of the auger rod 41, and the internal spline cooperates with the external spline.

[0072] The external splines of the rotating shaft 2 cooperate with the internal splines of the auger rod 41 , so that the driving motor 12 and the rotating shaft 2 cooperate to complete the driving process of the auger rod 41 .

[0073] In this embodiment, a mounting ring 71 is fixedly provided at the bottom of the filter sleeve 7, and the bottom of the mounting ring 71 is movable and passes through the top to the bottom of the isolation sleeve 3.

[0075] The mounting ring 71 completes the assembly design of the filter sleeve 7 on the isolation sleeve 3, wherein the inner tooth ring 72 cooperates with the outer tooth ring 73, and the rotating shaft 2 drives the outer tooth ring 73 to rotate, completing the rotation of the filter sleeve 7 on the isolation sleeve 3, making it convenient for the scraper 61 to scrape off the impurities on the outside of the filter sleeve 7, and the guide pipe guides water to the outside of the filter sleeve 7, and combines the sewage immersed in the outside of the filter sleeve 7 in the tank body 1 to perform an immersion flushing treatment on the outside of the filter sleeve 7.

[0076] In this embodiment, the outer side of the cover shell 8 is movably connected to the bottom of the inner wall of the tank body 1, the middle part of the cover shell 8 is movably connected to the bottom of the rotating shaft 2, the bottom of the cover shell 8 is movably connected with multiple limit springs 82, the other end of the limit spring 82 is movably connected to the bottom of the inner shell 9, the bottom of the cover shell 8 is movably connected with a waterproof electric push rod 83, and the output end of the waterproof electric push rod 83 is movably connected to the bottom of the inner shell 9.

[0077] After the cover shell 8 and the inner shell 9 are assembled, the inner shell 9 drives the cover shell 8 to move up and down below the isolation sleeve 3, and the waterproof electric push rod 83 completes the rotation of the cover shell 8 on the outside of the inner shell 9, completing the overlapping or misalignment processing of the first drainage hole 81 and the second drainage hole 91.

[0078] When the first drainage hole 81 and the second drainage hole 91 are misaligned, the inner shell 9 drives the cover shell 8 to rise, and the sewage filtered between the cover shell 8 and the isolation sleeve 3 is re-discharged into the top of the isolation sleeve 3 through the one-way valve 34 and the filter sleeve 7 respectively, so as to effectively remove the impurities adhering to the outside of the filter sleeve 7. If the inner shell 9 drives the cover shell 8 to descend, the speed of the sewage above the isolation sleeve 3 passing through the filter sleeve 7 is accelerated, so as to avoid a large amount of sewage from rushing into the water inlet pipe 13 in a short time and causing the sewage water level to rise into the top cover 11, and at the same time, the sewage below the inner shell 9 is pushed to be quickly discharged through the drain pipe 16.

[0079] When the first drainage hole 81 and the second drainage hole 91 overlap, the sewage treated by the filter sleeve 7 passes through the cover shell 8 and the inner shell 9 and is discharged to the sedimentation tank or other next sewage treatment process through the drainage pipe 16 .

[0083] After the cover shell 8 and the inner shell 9 are assembled, the inner shell 9 drives the cover shell 8 to move up and down below the isolation sleeve 3, and the waterproof electric push rod 83 completes the rotation of the cover shell 8 on the outside of the inner shell 9. When the first drainage hole 81 and the second drainage hole 91 are misaligned, the inner shell 9 drives the cover shell 8 to rise, and the sewage filtered between the cover shell 8 and the isolation sleeve 3 is re-discharged into the top of the isolation sleeve 3 through the one-way valve 34 and the filter sleeve 7 respectively, effectively removing impurities adhered to the outside of the filter sleeve 7, and avoiding excessive accumulation of impurities affecting the water filtering effect of the filter sleeve 7.

[0084] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
