Description

Technical Field

[0001] This utility model relates to the technical field of ore mining, and in particular to a magnetic separation device for ore mining. Background Technology

[0002] Magnetic separation of ores is a method that utilizes the magnetic differences between minerals to separate them in a non-uniform magnetic field. Before processing, the mined ore needs to undergo magnetic separation. Existing technology publication number CN218854419U proposes an iron ore magnetic separation device. Powered by a first and second motor, it utilizes double-layer grinding rollers in the feeding hopper, the magnetic drum's adsorption of iron ore powder within the separator, and the blowing force of a fan. This achieves a small footprint and easy separation of iron ore powder from other stone powders entering the separator. Scrapers remove the powder, and baffles and the discharge hopper prevent other stone powders from entering the loading frame, thus improving iron ore recovery. However, because it separates through a single magnetic separation, the iron ore travels a relatively short distance relative to the magnetic drum on the conveyor belt. This may cause other stone powders to not separate from the iron ore in time and be carried to the scraper, resulting in insufficient final magnetic separation efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an ore mining magnetic separation device that improves the magnetic separation effect and ensures the separation quality.

[0004] This utility model discloses a magnetic separation device for ore mining, comprising a separation box, multiple shock-absorbing base plates, a feeding assembly, a primary separation assembly, a secondary separation assembly, and a limiting component. Multiple shock-absorbing base plates are installed at the four corners of the bottom of the separation box. A feeding inlet is located on the left side of the top of the separation box, and the feeding assembly is installed at the feeding inlet. The primary separation assembly is installed on the upper side of the interior of the separation box, and the secondary separation assembly is installed on the lower side of the interior of the separation box. A limiting component that cooperates with the secondary separation assembly is installed at the front end of the separation box. Ore is fed into the separation box through the feeding assembly to avoid clogging. The ore falls onto the primary separation assembly for preliminary separation. The separated ore falls onto the secondary separation assembly for further magnetic separation, improving the magnetic separation effect and ensuring the separation quality.

[0005] Preferably, the feeding assembly includes a feeding hopper, multiple telescopic cylinders, a pusher plate, and multiple crushing rods. The feeding hopper is installed inside the feed inlet at the top of the sorting box. The multiple telescopic cylinders are evenly installed at the top of the sorting box. The telescopic end of the telescopic cylinder is equipped with a pusher plate, and the left end of the pusher plate is equipped with multiple crushing rods. The crushing rods extend through the side wall of the feeding hopper and into its interior. When ore is fed into the feeding hopper, it is fed into the sorting box. Activating the telescopic cylinder pushes the crushing rods to the left through the pusher plate, which can crush the ore when blockage occurs in the feeding hopper, thus preventing blockage.

[0006] Preferably, the preliminary sorting component includes two rotating rods, a conveyor belt, modular magnets, a drive motor, a receiving plate, a first discharge chute, and a rejection component. The two rotating rods are rotatably installed inside the upper side of the sorting box, and a conveyor belt is installed between the two rotating rods. Modular magnets are installed on the conveyor belt. The input end of the left rotating rod is connected to the output end of the drive motor. A discharge port is opened on the upper side of the right side wall of the sorting box, and the first discharge chute is installed at the discharge port. A receiving plate is installed on the inner wall of the discharge port. When the drive motor is started, it drives the rotating rods to rotate, causing the conveyor belt to rotate. The ore entering the sorting box falls onto the surface of the conveyor belt. At this time, the ore is attracted by the modular magnets on the conveyor belt. The ore that is not attracted falls to the top of the receiving plate and is discharged from the sorting box through the discharge port and the first discharge chute, thus performing preliminary sorting of the ore.

[0007] Preferably, the rejection component includes a mounting groove, multiple springs, and a scraper. The mounting groove is installed on the left inner wall of the sorting box below the conveyor belt. Multiple springs are installed inside the mounting groove. The scraper is slidably installed inside the mounting groove, with the bottom of the scraper connected to the top of the springs and the top of the scraper in contact with the outer surface of the conveyor belt. The conveyor belt drives the magnetically attracted ore to move. The scraper can push the ore attracted on the conveyor belt off. The springs can extend and retract the scraper within the mounting groove for vertical adjustment, making it convenient to use.

[0008] Preferably, the re-selection components include a reducer, a magnetic separation plate, a vibrator, a fine discharge chute, a second discharge chute, a forward and reverse motor, and a controller. The magnetic separation plate is mounted on the lower front and rear ends of the sorting box via a rotating shaft. The output end of the reducer is connected to the input end of the rear rotating shaft, and the input end of the reducer is connected to the output end of the forward and reverse motor. A vibrator is installed inside the magnetic separation plate. Discharge ports are opened on the lower part of the left and right side walls of the sorting box. The fine discharge chute is installed at the left discharge port, and the second discharge chute is installed at the right discharge port. The controller is installed at the lower end of the rear side wall of the sorting box. The ore falling downward by gravity lands on the top of the magnetic separation plate. The vibrator is activated to evenly distribute the ore on the surface. Then, the magnetic separation plate performs work to separate ores with different magnetic properties. The forward and reverse motor is activated to drive the magnetic separation plate to rotate through the reducer. The weakly magnetic ore is tilted to the right and discharged through the second discharge chute. Then, the plate rotates in the opposite direction. At the same time, the magnetic separation plate is de-energized, and the strongly magnetic ore is tilted to the left and discharged through the fine discharge chute. The controller is activated to facilitate the control of the equipment.

[0009] Preferably, the limiting component includes a mounting box, two telescopic cylinders, a limiting plate, and two limiting slips. The mounting box is installed at the front end of the sorting box, and telescopic cylinders are installed at both the upper and lower ends of the mounting box. The limiting plate is installed at the outer end of the front rotating shaft, and the telescopic ends of the telescopic cylinders are equipped with limiting slips. When the magnetic separator rotates to adjust the tilt angle, the telescopic cylinders are activated to push the limiting slips to contact the limiting plate, thereby limiting the magnetic separator and ensuring stability.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the ore is added into the sorting box through the feeding component, which can avoid clogging. The ore falls onto the primary sorting component for preliminary sorting. The sorted ore falls onto the secondary sorting component for secondary magnetic separation, which improves the magnetic separation effect and ensures the sorting quality.

[0019] Ore is fed into the feed hopper 3 and then into the sorting box 1. The telescopic cylinder 4 is activated, pushing the crushing rod 6 to the left via the push plate 5. This crushes the ore in case of blockage in the feed hopper 3, preventing further blockage. The drive motor 10 is activated, rotating the rotating rod 7 and causing the conveyor belt 8 to rotate. The ore entering the sorting box 1 falls onto the surface of the conveyor belt 8. At this time, the ore is attracted to the iron ore by the modular magnet 9 on the conveyor belt 8. The ore that is not attracted falls to the top of the receiving plate 11 and is discharged from the sorting box 1 through the discharge port and the first discharge chute 12, thus performing preliminary sorting of the ore.

The conveyor belt 8 moves the magnetically attracted ore. The scraper 15 pushes the ore adsorbed on the conveyor belt 8 down. The ore falling downwards by gravity lands on the top of the magnetic separation plate 17. The vibrator 18 is activated to make the ore on the surface evenly distributed.
