Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation in the production of corundum, in particular to magnetic separation equipment for the production of corundum. Background Art

[0002] Silicon carbide is also called diamond sand or refractory sand. Silicon carbide is made of quartz sand, petroleum coke, sawdust and other raw materials in a resistance furnace through high-temperature smelting. In the production and processing of corundum, magnetic separation equipment is used to separate the corundum in order to ensure its purity.

[0003] Announcement No. "CN213669844U" provides a magnetic separation equipment for corundum production. The corundum material is poured from a feed hopper, and the corundum falls to the surface of a screening barrel. At this time, the drive motor is controlled to run, driving the first pulley to rotate clockwise. The first pulley drives two groups of screening barrels to rotate clockwise through a transmission belt. The corundum first falls to the surface of the upper screening barrel, and a part of it is magnetically separated. It is scraped by a discharge plate and falls to the outside for loading. The fully magnetically separated corundum falls to the surface of the lower screening barrel for secondary rotation and magnetic separation.

[0004] However, the above technical solutions and the prior art have the following defects:

Its practicality needs to be improved. Utility Model Content

[0036] Working principle: During the corundum production process, the staff first starts the driving motor 43, so that the driving motor 43 drives the first permanent magnet tube 41 to rotate through the active support shaft 42, and at the same time, the active support shaft 42 drives the follower block 44 to rotate together, so that the follower block 44 drives the striking ball 46 to rotate together through the connecting spring 45. In this process, when the striking ball 46 rotates to the upper side, it will hit the box cover 2, so that the box cover 2 drives the magnetic separation box 1 to vibrate and shake off the corundum or iron impurities adhered to the inner wall; at the same time, the active support shaft 42 will drive the driven support shaft 51 to rotate together through the active pulley 55, the transmission belt 54 and the driven pulley 53, so that the driven support shaft 51 drives the second permanent magnet tube 52 to rotate synchronously (the rotation direction of the first permanent magnet tube 41 and the second permanent magnet tube 52 is in Figure 3 The staff can then feed the corundum to be magnetically separated into the hopper 3. During this process, the guide cavity 22 will guide the corundum in the hopper 3 downward to the upper side of the annular side of the first permanent magnetic cylinder 41. At the same time, the blocking plate 21 will block the guided corundum to prevent the corundum from sliding to the rear side. Most of the iron impurities in the corundum that slides to the annular side of the first permanent magnetic cylinder 41 will be adsorbed, and the corundum that slides down will continue to slide downward and be concentratedly guided downward by the first guide seat 56 and the shunt seat 47 to the upper side of the annular side of the second permanent magnetic cylinder 52 for secondary magnetic separation. The iron impurities adsorbed on the annular side of the first permanent magnetic cylinder 41 will be scraped off by the first scraping strip 49 and guided by the shunt seat 47 to the upper discharge cavity 16, and the upper discharge cavity 16 will guide the iron impurities. The iron impurities remaining in the corundum that falls to the upper collecting box 15 for collection will be adsorbed, and the corundum will continue to slide downward and be discharged to the outside by the discharge pipe 7, while the iron impurities adsorbed on the annular side of the second permanent magnetic tube 52 will be scraped off by the second scraping bar 58. At this time, the scraped iron impurities will be guided by the second guide seat 57 to the lower discharge cavity 13, and the lower discharge cavity 13 will guide the iron impurities to the lower collecting box 12 for collection, so as to effectively screen out the iron impurities in the corundum; in the later use process, the staff only needs to disassemble the fixing plate 481, and then they can pull the first support plate 48 and the second support plate 59 respectively, so as to take out the first scraping bar 49 and the second scraping bar 58 from the magnetic separation box 1 for replacement.
