After the filtering is completed, the collecting box 5 is taken out, and then the first mounting cylinder 3 is moved down as a whole, so that the second mounting cylinder 7 is close to the ground or platform, and then the mutual restriction of the fixed box 19 and the fixed block 24 is cancelled, and then the second mounting cylinder 7 and the first mounting cylinder 3 are separated, so that the second mounting cylinder 7 can be removed separately, so that the solid retained above the screen 8 inside the second mounting cylinder 7 can be quickly cleaned.

[0023] The connecting assembly includes a fixed block 24, which is fixed to the outer wall of the first mounting tube 3, and the top of the fixed block 24 is provided with a limiting groove 25, and the outer wall of the second mounting tube 7 is fixed with a fixed box 19 corresponding to the number of the fixed blocks 24, and the top of the fixed box 19 is rotatably installed with a rotating shaft 21, and the bottom of the rotating shaft 21 extends to the bottom of the fixed box 19, and the outer wall of the rotating shaft 21 inside the fixed box 19 is sleeved with a sliding block 20, and the outer side of the fixed box 19 is provided with a U-shaped fixed frame 17, and the bottom of both sides of the fixed frame 17 is fixed with a rotating rod 18, and one end of the rotating rod 18 is connected to one side of the sliding block 20 through a rotating shaft;
