[0029] The brush lint assembly 5 includes: bristles 51, a brush roller 52, and a feed port 53. The brush roller 52 is horizontally arranged above one side of the arc-shaped grid plate 9. The brush roller 52 adopts a bearing and a bearing seat to rotate with the filter bin 1. Hard bristles 51 are distributed on the brush roller 52. The length of the bristles 51 must meet the requirements that when the comb teeth 46 pass through the bristles 51, the bristles 51 can brush the comb teeth 46 and the comb plate 45. The end of the brush roller 52 away from the motor 42 adopts a belt drive assembly 11 and a rotating rod 43 to form a belt drive. The filter bin 1 is provided with a feed port 53 below the bristles 51 and the brush roller 52 as a whole, and the collecting box 7 is located directly below the feed port 53.

[0030] In order to facilitate the collection of filtered sewage, the bottom of the filter chamber 1 is inclined, and the water outlet 3 is arranged at the lowest part of the inclined bottom of the filter chamber 1 .

[0031] In order to facilitate the transportation of the collected sewage to the next step, the water outlet 3 is connected to a drainage pipe 8 of a pipeline structure.

[0032] In order to facilitate the movement of the collection box 7 and the drainage of the collection box 7, the collection box 7 is a box body 71 with upper and lower openings. The bottom of the box body 71 is closed with a dense mesh 72, and handles 73 are fixed on both sides of the box body 71.

[0033] The drain mechanism 6 includes a drain pan 61, an inclined bucket 62, and a secondary drain pipe 63; the drain pan 61 is used to support the collection box 7 and wrap the lower part of the collection box 7 (to facilitate water collection).

The flocculation is scraped to the flocculation brushing assembly 5, and the brush roller 52 in the flocculation brushing assembly 5 is rotated by the rotating rod 43 through the belt transmission assembly 11. The brush roller 52 drives all the bristles 51 to rotate, and the flocculation on the comb plate 45 and the comb teeth 46 is brushed off and falls from the drop port 53 to the collecting box 7 below. The dense mesh 72 below the collecting box 7 will prevent the flocculation from falling, and drain the water in the flocculation and receive it from the drain tray 61 and transfer it to the secondary discharge pipe 63 through the inclined bucket 62. The secondary discharge pipe 63 guides the drained water flow into the drain pipe 8 (this can avoid the flocculation water content in the collecting box 7 being too high, occupying the volume of the collecting box 7 and affecting the flocculation recovery operation). The water flow in the drain pipe 8 is the water flow after the flocculation is filtered, which can be transported to the next process by an external pipeline for the next purification operation. The flocculation drained in the collecting box 7 is recycled or disposed of as waste as appropriate, and the handle 73 is used to facilitate the overall movement of the collecting box 7.
