[0002] During the production process of white corundum, its raw material bauxite usually contains a certain amount of iron. In order to improve the purity and performance of white corundum, it is necessary to remove iron from the white corundum.

[0003] However, in the prior art, there is a Chinese utility model patent with authorization announcement number CN219985015U that discloses a magnetic separation and iron removal device for white corundum production. The device starts a motor through an external power supply. The start of the motor drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the stirring blades to rotate. The rotation of the stirring blades stirs the white corundum inside the filter so that the iron filings on the surface of the white corundum inside the filter can be fully attracted by the magnet, thereby ensuring that the iron filings on the surface of the white corundum can be cleaned. However, this solution has the following defects: during the iron removal process, the iron filings on the surface of the white corundum pass through the filter under the attraction of the magnet and adhere to the surface of the magnet. Once the mesh of the filter is blocked by small pieces of white corundum stones or large pieces of iron filings, the iron removal effect will be greatly reduced, and the iron removal efficiency will be significantly reduced.

[0040] The third sealing plug 420 is provided to prevent the white corundum from flowing out from the position where the third sealing plug 420 is located during the rotation of the magnetic cylinder 400 .

[0041] When it is necessary to discharge the iron filings inside the arc-shaped collecting tube 580, the staff first opens the fourth sealing plug 250, and then rotates the magnetic tube 400 at a low speed until the third sealing plug 420 rotates close to the fourth sealing plug 250. At this time, the staff opens the third sealing plug 420 again. At this time, the staff can insert the vacuum cleaner's dust collection tube into the arc-shaped collecting tube 580 and suck the iron filings in the arc-shaped collecting tube 580 into the vacuum cleaner.

[0042] As an embodiment of the present invention, Figure 8 As shown: the outside of the screen drum 200 is provided with a driving assembly 600, which includes a motor 610, a first pulley 620, a second pulley 630, a first gear 640 and a second gear 650. The motor 610 is provided on the outside of the screen drum 200, and the output shaft of the motor 610 is fixedly connected to the first pulley 620. The outside of the stirring shaft 510 is fixedly connected to the second pulley 630. The first pulley 620 is connected to the second pulley 630 by a belt. The outside of the stirring shaft 510 is also fixedly connected to the first pulley 620. A gear 640 and a second gear 650 are coaxially fixedly connected to the magnetic drum 400, and a third gear 660 and a fourth gear 670 are coaxially rotated in sequence from the outside to the inside on the outside of the sieve drum 200. Specifically, the third gear 660 and the fourth gear 670 are connected together by a connecting shaft, and the third gear 660 and the fourth gear 670 rotate synchronously. The connecting shaft is rotatably connected to the outside of the sieve drum 200, and the third gear 660 is meshed with the first gear 640, and the fourth gear 670 is meshed with the second gear 650.

[0043] The driving assembly 600 is provided to drive the assembly 600 and the magnetic cylinder 400 so that the scraper 590 can remove iron filings attached to the inner circumference of the rotating magnetic cylinder 400 .

[0044] As an embodiment of the present invention, Figure 9 As shown: the angle adjustment assembly 300 includes a fixed support frame 310, a limit plate 320, a guide roller 330, a wheel frame 340 and a jack 350. The fixed support frame 310 is arranged on the base 100, and the left part of the screen drum 200 is hinged to the fixed support frame 310. The jack 350 is arranged at the top right side of the base 100. The telescopic end of the jack 350 is fixedly connected to the wheel frame 340. The guide roller 330 is rotatably arranged on the wheel frame 340. The limit plate 320 is arranged at the lower end of the right part of the screen drum 200. The lower surface of the limit plate 320 is provided with a limit groove 321, and the guide roller 330 is rollingly connected in the limit groove 321.

[0045] An angle adjustment assembly 300 is provided for adjusting the inclination angles of the screen drum 200 and the magnetic drum 400, so that when feeding, the right end of the screen drum 200 is tilted downward, so that the white corundum entering the magnetic drum 400 from the feed hopper 210 can be evenly distributed inside the magnetic drum 400. In addition, when discharging, the left end of the screen drum 200 is tilted downward, so that the white corundum can be concentrated at the location of the discharge port 230, so that the white corundum can be completely discharged from the magnetic drum 400.

[0046] The working principle and use process of the utility model are as follows: the staff opens the feed hopper 210 and pours the white corundum to be deironed into the screen drum 200. The white corundum enters the interior of the magnetic drum 400 through the feed gap 410. At the same time, the staff retracts the jack 350 to make the right end of the screen drum 200 tilt downward, so that the white corundum rolls downward under the action of gravity and is evenly distributed along the axis of the magnetic drum 400 at the lower part of the magnetic drum 400. Next, the motor 610 is rotated. At this time, the motor 610 drives the first pulley 620 to rotate. The first pulley 620 rotates. The pulley 620 drives the second pulley 630 to rotate, the second pulley 630 drives the stirring shaft 510 to rotate, the stirring shaft 510 drives the stirring sleeve 520 to rotate, the stirring sleeve 520 drives the fixed cylinder 530 to rotate, the fixed cylinder 530 drives the sliding rod 540 to rotate, the sliding rod 540 drives the toggle plate 550 to rotate, and under the action of gravity, when the sliding rod 540 rotates to the upper part of the magnetic cylinder 400, under the action of gravity of the sliding rod 540 and the toggle plate 550, the sliding rod 540 moves along the T-shaped slot 531 to approach the stirring sleeve 520 The toggle plate 550 moves in the direction of the axis. At this time, the toggle plate 550 does not contact the arc-shaped collecting cylinder 580. When the sliding rod 540 rotates to the lower part of the magnetic cylinder 400, under the action of the gravity of the sliding rod 540 and the toggle plate 550, the sliding rod 540 moves along the T-shaped groove 531 in the direction away from the axis of the stirring sleeve 520. At this time, the toggle plate 550 can toggle the white corundum at the bottom of the magnetic cylinder 400, so that the iron filings on the surface of the white corundum can be adsorbed on the inner circumference of the magnetic cylinder 400. At the same time, the stirring shaft 510 drives the first gear 640 to rotate. The first gear 640 drives the third gear 660 to rotate, the third gear 660 drives the fourth gear 670 to rotate synchronously through the connecting shaft, the fourth gear 670 drives the second gear 650 to rotate, and the second gear 650 drives the magnetic cylinder 400 to rotate. At this time, the iron filings adsorbed on the inner wall of the magnetic cylinder 400 can gradually rotate to the position of the scraper 590. Under the blocking effect of the scraper 590, the iron filings fall from the inner wall of the magnetic cylinder 400 and fall into the interior of the arc-shaped collecting cylinder 580 through the opening at the upper part of the arc-shaped collecting cylinder 580.

[0047] After the device has been working continuously for a certain period of time, the staff can first remove the second sealing plug 240 from the discharge port 230. At this time, a portion of the white corundum will fall from the discharge port 230. After collecting a certain amount of white corundum, the iron filings content on the surface of the white corundum is measured. If the iron filings content on the surface of the white corundum is lower than the preset value, the jack 350 can be lifted upward to tilt the left end of the screen drum 200 downward to facilitate the discharge of all the white corundum from the discharge port 230. If the measured iron filings content on the surface of the white corundum is higher than the preset value, the second sealing plug 240 is threadedly connected to the discharge port 230 to remove iron from the white corundum until the iron filings content on the surface of the white corundum is lower than the preset value, and then all the white corundum is discharged.

[0048] When it is necessary to discharge the iron filings inside the arc-shaped collecting tube 580, the staff first opens the fourth sealing plug 250, and then rotates the magnetic tube 400 at a low speed until the third sealing plug 420 rotates close to the fourth sealing plug 250. At this time, the staff opens the third sealing plug 420 again. At this time, the staff can insert the vacuum cleaner's dust collection tube into the arc-shaped collecting tube 580 and suck the iron filings in the arc-shaped collecting tube 580 into the vacuum cleaner.

[0049] In summary, compared with the existing technology, this device does not need to set up a filter to isolate the white corundum and the magnet. Instead, the magnet is set as a magnetic cylinder 400. Through the rotation of the magnetic cylinder 400 and the stirring of the stirring component 500, the iron filings in the white corundum gradually adhere to the inner wall of the magnetic cylinder 400, and then the iron filings on the inner wall of the magnetic cylinder 400 are scraped off by the scraper 590. In this way, the iron filings on the surface of the white corundum can be efficiently removed, and the iron removal effect of the device will not be greatly reduced due to the blockage of the filter mesh, which is beneficial to improving the iron removal efficiency of the iron removal device.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
