The feed valve 7 can control the amount of liquid inlet to prevent the phenomenon of untimely filtration due to excessive residual liquid.

[0044] Start the first motor 33 to drive the threaded rod 34 to rotate. Under the limiting action of the slide bar 32, the slider 31 is driven to slide left and right in the collection box 1. The slider 31 drives the scraper 35 and the brush 36 to slide left and right, so that the brush 36 cleans the filter box 511 to prevent the residue from clogging the filter box 511 and affecting the residual liquid filtration.

The vertical stirring rod 43 vertically stirs the filtered residual liquid and the precipitant. The rotation of the first rotating rod 42 drives the driving bevel gear 47 to rotate, thereby driving the driven bevel gear 46 meshing with the driving bevel gear 47 to rotate, and then drives the second rotating rod 45 and the horizontal stirring rod 44 to rotate, and stir the residual liquid horizontally. The filtered residual liquid and the precipitant are stirred vertically and horizontally, so that the residual liquid and the precipitant are fully mixed, the reaction speed is accelerated, and the residual liquid is easy to be recycled.

[0048] The fan 21 is started, and the odor in the collection box 1 is deodorized by the deodorization box 23 and then discharged to the outside by the fan 21, so as to prevent the untreated odor from affecting the outside.
