The end of the drain pipe 5 away from the box body 2 is connected to the cleaning box 41. The cleaning box 41 is provided with an opening 45. The placement piece 42 is provided inside the opening 45.

[0025] By adopting the above technical solution, during the sludge extraction process, the water inside the box body 2 falls into the cleaning box 41 through the drain pipe 5, and diffuses into the placement part 42 through the pores on the placement part 42. After the subsequent use of the silt extraction mechanism 3 is completed, the end of the silt extraction mechanism 3 is placed into the placement part 42 through the opening 45, and the water inside the placement part 42 is used to clean the parts of the silt extraction mechanism 3 to ensure the cleanliness of the parts of the silt extraction mechanism 3, thereby ensuring the subsequent use effect of the silt extraction mechanism 3, and the cleaning box 41 can be used to store and place the parts of the silt extraction mechanism 3.

[0026] Specifically, the placement member 42 includes a placement net box 421, a top frame 422, a threaded barrel 423, a fixed screw 424 and a side rod 425. The net box 421 is arranged inside the opening 45, and the end of the placement net box 421 close to the opening 45 is connected to the top frame 422. One side of the top frame 422 is connected to the side rod 425. A side groove is provided on the side wall of the cleaning box 41 at a position corresponding to the side rod 425.

[0030] When this embodiment is used, the side rod 425 is aligned with the position of the side groove, and the net box 421 is placed inside the cleaning box 41 through the opening 45. The side rod 425 then passes through the fixed screw 424 and overlaps the inside of the side groove. Then the threaded cylinder 423 is rotated and screwed onto the fixed screw 424. Then, one end of the silt extraction mechanism 3 is placed inside the sewage treatment pool. The silt at the bottom of the sewage treatment pool is extracted into the screen 8 by the silt extraction mechanism 3. The rotating mechanism 7 is then used to drive the dewatering barrel 6 to rotate. The rotation of the dewatering barrel 6 drives the screen 8 to rotate. During the rotation of the dewatering barrel 6, the water content of the silt can be removed by centrifugal force. The discarded water falls into the cleaning box 41 through the drain pipe 5 and diffuses into the placement net box 421 through the pores of the placement net box 421. After the sludge at the bottom of the sewage treatment pool is extracted, the silt extraction mechanism 3 is taken out from the sewage treatment pool, and the end of the silt extraction mechanism 3 is placed into the placement net box 421 through the opening 45. The water inside the placement net box 421 is used to clean the components of the silt extraction mechanism 3 to ensure the cleanliness of the components of the silt extraction mechanism 3, thereby ensuring the subsequent use effect of the silt extraction mechanism 3, and the cleaning box 41 can be used to store and place the components of the silt extraction mechanism 3.
