The scraper 51 has a certain curvature and is inclinedly arranged, so that the scraper 51 can push the agglomerated magnetic materials to move downward along the outer peripheral surface of the inner cylinder 3. On the one hand, the agglomerated magnetic materials are gradually accumulated and continuously increased in volume under the pushing of the scraper 51, so as to be moved downward by gravity and separated from the magnetic attraction structure; on the other hand, the agglomerated magnetic materials are pushed downward by the scraper 51, which helps to gradually move away from the magnetic attraction structure, so as to be separated to the lower end of the outer cylinder 2 and then discharged through the discharge port 23. The scraper 51 is uniformly provided with a plurality of through holes 511, which helps the ore pulp to pass through and reduces the resistance received by the scraper 51, thereby improving the reliability.
