[0032] Embodiment 1: In order to solve the problem that the impurity separation device currently on the market can fix the rare earth permanent magnetic material under the action of magnetic force when separating impurities from the rare earth permanent magnetic material, but there are still other problems in this treatment.

The top positions of the lower electromagnetic plate 11 and the upper electromagnetic plate 12 can adsorb rare earth permanent magnetic materials. When screening the rare earth permanent magnetic materials of different shapes and particle sizes inside the separation box 1, firstly, the fixed motor 4 is started so that the output end of the fixed motor 4 drives the stirring rod 5 to rotate, causing the rotating gear 6 set at the outer position of the stirring rod 5 to drive the matching gear 7 to rotate. Since the outer position of one end of the matching gear 7 is connected to the end of the fan gear 9 through the first transmission assembly 8, the fan gear 9 will drive the two sets of connecting tooth plates 10 to move during the rotation.
