[0023] In one embodiment, the magnetic separator 101 has a movable groove 103 on one side that is fixedly connected to a fixed frame 201. The fixed frame 201 has sliding grooves 202 on both sides. The inner wall of a set of sliding grooves 202 is rotatably connected to the outer wall of one end of a threaded screw 203 through a bearing. The other end of the threaded screw 203 is fixedly connected to the output end of a drive motor 204 through a coupling. The inner side of the fixed frame 201 is fixedly connected to both ends of a central tube 205. One side of the central tube 205 is fixedly connected to one side of a bellows 206.

[0024] Specifically: the drive motor 204 is started to drive the threaded screw 203 to rotate, which in turn drives the internal thread moving block 212 to move along the outer wall of the threaded screw 203, which in turn drives the jet frame 209 to move through the limit of the slider 211.

[0025] In one embodiment, the other side of the central tube 205 is fixedly connected to one end of the air outlet tube 207, the other end of the air outlet tube 207 is fixedly connected to the air outlet end of the air pump 208, and one side of the air outlet tube 207 is fixedly connected to one side of the magnetic separator 101.

[0027] In one embodiment, the inner wall of the moving groove 103 is movably connected to the outer wall of the jet frame 209, one side of the jet frame 209 is fixedly connected to one end of the connecting pipe 210, the other end of the connecting pipe 210 is fixedly connected to the other end of the bellows 206, one side of the jet frame 209 is fixedly connected to one side of the slider 211, the other side of the jet frame 209 is fixedly connected to one side of the internally threaded moving block 212, the outer wall of the slider 211 is movably connected to the inner wall of a set of sliding grooves 202, the outer wall of the internally threaded moving block 212 is movably connected to the inner wall of another set of sliding grooves 202, the inner wall of the internally threaded moving block 212 is threadedly connected to the outer wall of the threaded screw 203, the side of the jet frame 209 away from the connecting pipe 210 is fixedly connected to the side of the air nozzle 213, and the interior of the air nozzle 213 communicates with the interior of the connecting pipe 210.

[0028] Specifically: As the jet frame 209 approaches the magnetic separator 107, the airflow impact force increases. By adjusting the distance between the jet frame 209 and the magnetic separator 107, it is easier to clean different residual impurities and the applicability of cleaning is increased.

[0029] Working principle: Material enters the magnetic separator 101 through the feeding hopper 102. The servo motor 109 is started to drive the magnetic separator 107 to rotate. At the same time, the semi-circular magnet 108 is fixedly installed inside the magnetic separator 107. Magnetic substances in the material are attracted to the outer wall of the magnetic separator 107 by the semi-circular magnet 108, while non-magnetic substances are discharged through the impurity discharge trough 105. As the magnetic separator 107 rotates, when the magnetic substances move away from the magnetic field range of the semi-circular magnet 108, they are simultaneously discharged through the magnetic material discharge trough 106 by the centrifugal force of the magnetic separator 107. The air pump 208 is then started. The gas is blown through the central pipe 205, corrugated pipe 206, connecting pipe 210 and air nozzle 213 onto the magnetic separator 107, thereby blowing off the material remaining on the outer wall of the magnetic separator 107. When cleaning highly viscous materials, the drive motor 204 is started to drive the threaded screw 203 to rotate, which in turn drives the internal thread moving block 212 to move along the outer wall of the threaded screw 203, which in turn drives the air jet frame 209 to move through the limit of the slider 211. As the air jet frame 209 gets closer to the magnetic separator 107, the airflow impact force increases. The material after magnetic separation needs to be repeatedly magnetically separated again.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
