[0026] Working principle: Magnetic separator is a kind of mechanical equipment widely used in mining industry, including magnetite, pyrrhotite, roasted ore and ilmenite, etc. Among them, wet magnetic separator can drive the material to move by water flow, and screen out metals such as iron from the material by its own magnetic field strength. In the processing of existing magnetic separator, when the material particles are large, the flowing water cannot drive them to move, so that they are easily accumulated on the bottom side of the hopper, causing blockage inside the hopper. At this time, the cylinder body is in contact with the material and the friction and wear will increase, causing the magnetic separator to be unable to be used normally. In order to solve this problem, a loosening mechanism and a positioning mechanism are set up, and the insertion rod 15 is pulled out from the inside of the positioning hole 19, and then the turntable 14 is rotated to move the insertion rod 15 to the desired positioning hole 19, and the insertion rod 15 is released.

Water is injected into the inner side of the pipe 25, and the servo motor 21 is controlled to drive the small pulley 22 to rotate, so that the cooperation of the belt 24 and the large pulley 23 drives the cylinder 11 to rotate, and materials are added from the top side of the feeding bin 31. At the same time, the water pump 6 is turned on to input water into the inner side of the water tank 5 with the cooperation of the output pipe 7, so that the water source is sprayed out from the inner through hole 4 of the feeding bin 31 through the water pipe 2. At this time, the water flow will push the materials accumulated on the bottom side of the feeding bin 31, so that it can move with the water flow, thereby realizing the function of loosening the materials, bringing The magnetic material is adsorbed on the surface of the cylinder 11 and moves to the top side of the support plate 1. The water spray pipe 25 flushes the material and outputs it from the top side of the concentrate bin 34. At the same time, the magnetically separated material enters the discharge bin 32 with the water flow and is discharged from the discharge pipe 33 to the surface of the filter plate 9. At this time, the filter plate 9 filters out the material and stores the water source in the inner side of the circulating water tank 8. The water is then transported to the water pump 6 through the conduit 10 for recycling, thereby reducing the waste of water resources and solving the problem of material accumulation inside the magnetic separator, which causes blockage inside the magnetic separator.
