[0030] 2. Filtration and impurity removal process: An inclined filter plate 9 is fixedly arranged inside the box body 2. When the pulp passes through the filter plate 9, most of the impurities can be filtered out of the pulp during the tilting process. The impurity outlet 12 is located on the side of the box body 2 and close to the lowest point of the filter plate 9, which can discharge the filtered impurities.

[0032] 4. Cleaning of the filter holes of the drum: By arranging a scraper 6 and a brush 7 inside the drum 3, the pulp on the surface of the drum 3 can be cleaned to prevent the filter holes from being blocked and ensure the filtering effect. When the drum 3 is rotating, the scraper 6 is driven by the electric push rod 8 to be in the center of the drum to avoid affecting the centrifugal process of the internal pulp. When cleaning the inner wall of the drum, the scraper 6 and the brush 7 are driven to contact the inner wall of the drum, and then the drum 3 is driven to rotate, and the brush 7 scrapes off the pulp attached to the inner wall of the drum 3.
[0033] The above is the process of filtering and removing impurities from the pulp in this embodiment. Impurities and magnetic substances in the pulp are effectively filtered through the filter plate 9, impurity outlet 12 and annular magnet 11 in the box body 2. The rotation of the drum 3 and the cleaning of the scraper 6 ensure the smoothness of the filter holes, improve the filtering effect, and thus improve the quality of the pulp.
