When the filter bucket 3 is used to filter sewage, if it is found that the sewage filtering speed of the filter bucket 3 is slow, it is only necessary to lift the movable plate 34 upward, and the U-shaped rod 35 is disengaged from the locking groove on the fixing block 36, so that the filter bucket 3 can be conveniently taken out from the water inlet pipe 2 and replaced with a new filter bucket 3 for use. The removed filter bucket 3 can be thoroughly cleaned, so as to avoid that when cleaning the blockage on the filter bucket 3, large impurities on the filter bucket 3 will become small impurities and enter the filter box 1 through the filter holes on the filter bucket 3.

[0025] The working principle is as follows: the sewage is filtered by using the filter bucket 3 on the water inlet pipe 2. After the filter bucket 3 has been used for a period of time, it is found that the filtering effect on the filter bucket 3 is significantly reduced. Therefore, it is only necessary to manually lift the movable plate 34 on the positioning rod 33 in the installation grooves 32 on both sides. The movable plate 34 drives the locking spring 37 to be compressed. At the same time, the movable plate 34 drives the U-shaped rod 35 to move upward and disengage from the locking groove on the fixed block 36. Therefore, the filter bucket 3 can be conveniently removed from the water inlet pipe 2 for cleaning, so as to avoid that large impurities on the filter bucket 3 will be cleaned into small impurities and enter the filter box 1 during the cleaning process, thereby increasing the filtering burden in the filter box 1. After the use of the filter box 1 is over, the inner wall of the filter box 1 needs to be cleaned in time. At this time, it is only necessary to start the switch on the water pump 49 on the side of the liquid storage tank 48 on the support plate 47, and use the water pump 49 draws the cleaning liquid in the liquid storage tank 48 into the injection pipe 410, flows into the rotating rod 4 through the injection pipe 410, and sprays the cleaning liquid onto the inner wall of the filter box 1 through the discharge pipe 44. At the same time, the switch of the servo motor 41 on the mounting frame 42 is started, and the servo motor 41 is used to drive the rotating rod 4 to rotate, so that the discharge pipe 44 can evenly spray the cleaning liquid onto the inner wall of the filter box 1. At the same time, when the rotating rod 4 rotates, the transfer rod 45 will be driven to rotate, and the transfer rod 45 will drive the connecting rod 412 to rotate, and the connecting rod 412 will drive the scraper 46 to rotate, so that the impurities attached to the inner wall of the filter box 1 can be easily cleaned. At the same time, the tension of the retaining spring 411 in the transfer rod 45 can be used to drive the connecting rod 412 to move outward, so that it can drive the scraper 46 to fit tightly with the inner wall of the filter box 1, thereby cleaning the inner wall of the filter box 1.

[0026] Embodiment 2: On the basis of embodiment 1, a cleaning structure is installed on the filter box 1. In order to facilitate the rapid cleaning of the inner wall of the filter box 1, a cleaning structure is arranged on the inner wall of the filter box 1, specifically comprising a rotating rod 4, the rotating rod 4 is rotatably installed on the filter box 1, two drainage pipes 44 are symmetrically installed on the rotating rod 4, two groups of transfer rods 45 are symmetrically installed on the rotating rod 4, two connecting rods 412 are slidably installed on the two groups of transfer rods 45, scrapers 46 are installed on the two connecting rods 412, the scrapers 46 are in contact with the inner wall of the filter box 1, the two groups of transfer rods 45 and the two groups of drainage pipes 44 are cross-shaped, a support frame 43 is installed on the bottom side of the rotating rod 4, the support frame 43 is installed on the inner wall of the filter box 1, a retaining spring 411 is installed on the inner wall of the transfer rod 45, and the other end of the retaining spring 411 is installed on the connecting rod 412. A support plate 47 is installed on the rotating rod 4, and a liquid storage tank 48 is installed on the support plate 47. A water pump 49 is installed on the liquid storage tank 48, and a liquid injection pipe 410 is installed on the water pump 49. The liquid injection pipe 410 is installed on the rotating rod 4. A servo motor 41 is installed on the top of the rotating rod 4, and a mounting frame 42 is installed on the servo motor 41. The mounting frame 42 is installed on the filter box 1.
