[0019] A magnetic separation device for waste magnesia-carbon bricks, comprising a material conveyor belt body 1, two side baffles 11 are symmetrically fixedly installed on the upper surface of the frame of the material conveyor belt body 1, a feed hopper 2 is fixedly installed between the left ends of the two side baffles 11, a V-shaped plate 3 is fixedly installed in the feed hopper 2, a plurality of discharge ports 31 are penetrated through the upper surface of the V-shaped plate 3, and the plurality of discharge ports 31 are arranged transversely, a clearing mechanism 4 for clearing the discharge ports 31 is installed in the feed hopper 2, and the clearing mechanism 4 is located above the V-shaped plate 3, a material guide frame 6 is fixedly installed between the right ends of the two side baffles 11, a magnetic separation roller 7 with an axis is rotatably installed in the material guide frame 6, a scraper 61 is fixedly installed in the material guide frame 6, and the left end of the scraper 61 is in contact with the outer surface of the magnetic separation roller 7 with an axis, a circulating combing device 5 is installed between the two side baffles 11, and the circulating combing device 5 is located between the feed hopper 2 and the magnetic separation roller 7 with an axis;

[0020] It should be noted that, combined with Figure 2As shown, the circulating combing device 5 includes a screw A51 and a screw B52, which are rotatably installed between the two side baffles 11, and the outer surfaces of the screws A51 and B52 are both screwed with a combing rake 53, and the rear ends of the screws A51 and B52 are sleeved with a pulley 54, and a transmission belt 55 is arranged between the two pulleys 54, four directional rods 56 are fixedly installed between the two side baffles 11, and the combing rake 53 is slidably installed between the corresponding two directional rods 56, and the front surface of the front side baffle 11 is fixedly installed with a motor B57, and the output end of the motor B57 is fixedly connected to the front end of the screw A51;

[0021] Motor B57 is a forward and reverse motor, and the thread directions of screw A51 and screw B52 are opposite. When motor B57 is started, the cooperation between pulley 54 and transmission belt 55 can be used to drive screw A51 and screw B52 to rotate synchronously. When screw A51 and screw B52 rotate synchronously in the forward direction, the two combing rakes 53 move synchronously inward. When screw A51 and screw B52 rotate synchronously in the reverse direction, the two combing rakes 53 move synchronously inward and outward. According to the width of the material conveyor belt body 1, the drive motor B57 is used to drive screw A51 and screw B52 to switch between forward and reverse rotation according to the frequency of movement, thereby achieving the purpose of combing the magnesia-carbon brick waste with the combing rake 53, so that it can be more evenly distributed on the material conveyor belt body 1, which is more convenient for screening iron metal in the waste.

[0022] When in use, the magnesium carbon brick waste is put into the feed alley 2, and the magnesium carbon brick waste is installed at a certain distance through the discharge port 31 of the V-shaped plate 3 and falls onto the material conveyor belt body 1. As the material conveyor belt body 1 moves, the magnesium carbon brick waste is moved to the position of the combing rake 53. The circulating combing rake 53 flattens the magnesium carbon brick waste to make it more evenly distributed on the material conveyor belt body 1, and finally moves to the belt shaft magnetic separation roller 7. The iron metal in the magnesium carbon brick waste is adsorbed onto the outer surface of the belt shaft magnetic separation roller 7, and as the belt shaft magnetic separation roller 7 is driven by the scraper 61 to hang down, the iron metal finally falls from the guide frame 6, and the screened magnesium carbon brick waste can be collected at the discharge end of the material conveyor belt body 1.

[0023] It is worth noting that if Figure 3As shown, the clearing mechanism 4 includes a rotating roller 41 rotatably mounted on the feed hopper 2, a plurality of cleaning rods 411 are fixedly mounted on the outer surface of the rotating roller 41, the cleaning rods 411 rotate along the axis of the rotating roller 41 and can smoothly pass through the corresponding discharge port 31, a motor A42 is fixedly mounted on the front surface of the feed hopper 2, the output end of the motor A42 is fixedly connected to the front end of the rotating roller 41, and in the process of using the feed hopper 2 to discharge materials, the motor A42 can be used to drive the rotating roller 41 to rotate, thereby using the cleaning rods 411 to rotate toward the discharge port 31 to clean out the materials stuck in the discharge port 31, so as to avoid affecting the discharge of the feed hopper 2.

[0024] In addition, if Figure 1 or Figure 2 As shown, a turning feed hopper 62 is integrally formed at the right end of the guide frame 6, and the discharge end of the turning feed hopper 62 is set at the rear. Through the setting of the turning feed hopper 62, the discharge position of the screened iron metal can be changed to the rear of the equipment, and the iron metal discharge position and the discharge position of the screened magnesia carbon brick waste can be staggered to avoid affecting material collection.

[0025] Specifically, if Figure 1 As shown, a motor C71 is fixedly installed on the front surface of the guide frame 6, and the output end of the motor C71 is fixedly connected to the front end of the belt shaft magnetic separation roller 7. The motor C71 is used to drive the belt shaft magnetic separation roller 7 to rotate.
