The outer side of the filter core 5 is provided with a plurality of magnetic medium column bodies 6. Specifically, the length of the magnetic medium column body 6 matches the length of the filter core 5. The plurality of magnetic medium column bodies 6 are uniformly distributed along the circumferential direction of the filter core 5. The open end of the filter core 5 is connected to the outlet end of the cylinder 1. The outer side of the cylinder 1 is wound with a coil 2. In operation, the coil 2 is connected to a direct current. After the coil 2 is connected to the power supply, a magnetic field is generated. The magnetic medium column bodies 6 are magnetized. The slurry is input from the inlet end of the cylinder 1, filtered through the side of the filter core 5, and then enters the filter core 5.
