Paper pulp filtering device for waste paper recycling

The utility model relates to the technical field of filtering of recycled paper pulp, in particular to a paper pulp filtering device for recycling waste paper. The utility model aims to solve the technical problems that metal scraps in paper pulp cannot be separated, and a filtering system is high in manufacturing cost and insufficient in filtering. In order to solve the technical problem, the utility model provides the impurity removing device which comprises a base, and the top of the base is sequentially and fixedly connected with an impurity removing box from left to right. According to the pulp filtering device, pulp in the impurity removing box is adsorbed through rotation of the roller, metal fragments adsorbed on the roller are scraped and collected in a centralized mode through the scraping plate, the follow-up pulp filtering process is not interfered by the metal fragments, efficiency is high, practicability is high, and through layered filtering of the two layers of sieve plates which are obliquely
