[0023] A solid impurity collecting tank 2 is provided on the side of the separation box 1, and the solid impurity collecting tank 2 is used to collect the filtered solid impurities.

[0024] The filter screen 4 forms a hollow hemispherical structure, and a filter cloth 9 adapted thereto is fixed to the top of the inner portion of the filter screen 4; Figure 2As shown, the top edge of the filter cloth 9 is fixed to the filter screen 4, and the bottom end of the filter cloth 9 is attached to the filter screen 4 under the action of gravity; the bottom end of the filter cloth 9 is rotatably connected to the moving rod 6, and the moving rod 6 penetrates the fixed cover plate 5; the side of the moving rod 6 is fixed with a lifting assembly 3, and the lifting assembly 3 adopts the ball screw principle. The lifting assembly 3 includes a lifting motor 31, a screw rod 32, a nut 33, a cross bar 34 and a shell 35. The shell 35 is fixed to the side of the solid impurity collecting tank 2, and the inside of the shell 35 is equipped with a lifting motor. The lifting motor 31 is connected to the screw rod 32 at the output end thereof, and the screw rod 32 is connected to the nut 33; a cross bar 34 is provided on the side of the nut 33, and the cross bar 34 is connected to the moving rod 6; the lifting motor 31 is started, and the screw rod 32 is driven to rotate when the lifting motor 31 is started, thereby driving the nut 33 to be lifted and lowered, and the lifting and lowering of the nut 33 drives the cover plate 5 to be lifted and lowered at the top of the separation box 1; when solid-liquid separation is performed, the cover plate 5 is covered on the top of the separation box 1 to prevent liquid from flowing out; the cover plate 5 rises when solid impurities are processed after separation.

[0025] A water injection pipe 7 is fixedly passed through the surface of the cover plate 5 , wherein the water injection pipe 7 is used to add a treatment agent to be filtered into the filter cloth 9 .
