Insert rods 17 are fixed at the bottom of the side connecting columns 18.

[0024] The filter layer body 14 is evenly distributed in the first hollow groove 13, and the filter membrane layer 7 is assembled in the filter box 1 at the position above the filter cylinder 6.

[0025] The side connecting columns 18 are symmetrically distributed about the central axis of the filter cartridge 6, and the positioning holes 16 are symmetrically distributed about the central axis of the bearing ring 5.

[0026] The outer diameter of the insertion rod 17 is smaller than the inner diameter of the positioning hole 16, and the vertical positions of the insertion rod 17 and the positioning hole 16 correspond one-to-one.

[0027] The bottom of the filter box 1 has a discharge hole 3, and the bottom of the filter box 1 is connected to the discharge port 2. The ramp blocks 4 are symmetrically distributed about the central axis of the filter box 1.
