[0032] Working principle: The device is installed in a suitable location and connected to a municipal power supply. Paper pulp is injected into the slag removal tank 1 through the injection pipe 12. When the pulp enters the slag removal tank 1, the impeller 8 drives the connecting rod 5 to rotate. The dispersing disc 13 disperses the pulp flowing into the slag removal tank 1. The dispersing disc 13 then guides the pulp that has dispersed to the inner wall of the slag removal tank 1 to flow towards the filter screen cylinder 3 for filtration, removing the slag from the pulp. When the connecting rod 5 rotates, the pulp... The connecting rod 5 and the rotating sleeve 4 rotate together under the action of the fixed box 7, the lower bevel gear 71, the upper bevel gear 72 and the connecting bevel gear 73. The filter screen cylinder 3 is cleaned by the brush of the rotating frame 41. The slurry on the bottom wall of the slag removal tank 1 is drawn out by the pump body 9 and transported to the injection pipe 12 by the circulation pipe 91 and flows back into the slag removal tank 1 for repeated filtration and slag removal. The slag inside the slag removal tank 1 is discharged by opening the cover at one end of the slag discharge pipe 14.
