Description

Technical Field

[0001] The utility model relates to the technical field of iron ore magnetic separation, in particular to an iron ore magnetic separation device. Background Art

[0002] When smelting and mining enterprises produce iron ore, they need to grind the collected ore into slurry and then extract the iron ore. In order to obtain high-grade iron ore, magnetic separators are generally used to separate the iron ore. Among them, wet magnetic separation of slurry is one of the most widely used methods in the industry.

[0003] In the process of magnetic separation of iron ore currently available in the existing magnetic separation equipment, due to the large-scale discharge of slurry, the iron ore will be partially deposited in the slurry, and only the iron ore on the surface of the slurry will contact the magnetic plate, which will make it difficult for the magnetic plate to fully contact the iron ore in the slurry. The iron ore in the slurry cannot be fully screened out, and workers are required to stir the slurry, which consumes a lot of manpower, and the magnetic separation effect is not good, which reduces the magnetic separation efficiency. Utility Model Content

[0004] In order to overcome the existing defects, the utility model provides an iron ore magnetic separation device which can enable an arc-shaped magnet frame to more fully adsorb iron ore, thereby improving the magnetic separation efficiency.

[0005] The technical implementation scheme of the utility model is: an iron ore magnetic separation and separation device, comprising a magnetic separation box, a blanking trough is opened inside the magnetic separation box, the inner bottom of the magnetic separation box is inclined, the bottom of the magnetic separation box is fixedly connected to a discharging frame, and the discharging frame is located below the blanking trough of the magnetic separation box, the top of the magnetic separation box is fixedly connected to a feeding frame, one side of the magnetic separation box is fixedly connected to a fixing frame, the fixing frame is fixedly connected to a motor, the upper part of the magnetic separation box is rotatably connected to a hollow roller, one end of the hollow roller is fixedly connected to the output shaft of the motor, an arc magnet frame is fixedly connected inside the hollow roller, the partition plate is fixedly connected inside the magnetic separation box, and the partition plate is located between the blanking trough on the magnetic separation box and the hollow roller, the top of the magnetic separation box is fixedly connected to a scraper frame, the scraper frame is located above the partition plate, and the scraper frame is in contact with the hollow roller.

[0006] Furthermore, it also includes a fixed plate, which is fixedly connected to both sides of the outer wall of the magnetic separation box, and a material guide frame is slidably connected between the two fixed plates. The lower part of the material guide frame is located below the hollow roller, and a reset spring is connected between the material guide frame and the two fixed plates. Two cams are fixedly connected to the hollow roller, and the two cams are in contact with the top of the material guide frame.

[0007] Furthermore, it also includes threaded rods, three of which are rotatably connected in the magnetic separation box, stirring plates are fixedly connected to the three threaded rods, three guide rods are fixedly connected to the bottom of the guide frame, and one end of the guide rod is connected to the threaded rod by a thread.

[0008] Furthermore, it also includes a connecting rod, both sides of the lower part of the guide frame are rotatably connected to the connecting rod, a scraper is rotatably connected between the ends of the two connecting rods away from the guide frame, and the scraper is slidably connected to the bottom surface of the magnetic separation box.

[0009] The beneficial effects of the utility model are as follows: a worker starts the motor, and the output shaft of the motor drives the hollow roller to rotate. At the same time, the worker pours the slurry onto the hollow roller through the feeding frame. The slurry flows downward along the arc surface of the hollow roller, and the slurry falls into the magnetic separation box through the arc surface of the hollow roller. The rotation of the hollow roller drives the arc-shaped magnet frame to rotate, so that a large amount of iron ore adheres to the surface of the hollow roller, and the iron ore on the hollow roller is scraped by the scraper frame until the iron ore falls from the hollow roller, and the iron ore slides along the inclined surface of the partition plate into the drop chute of the magnetic separation box, and is discharged through the discharging frame, and this reciprocating process is repeated, thereby quickly screening out the iron ore in the slurry.

[0010] When the hollow roller rotates, it will drive the two cams to rotate, and the rotation of the two cams will drive the guide frame to move downward, and the return spring will drive the guide frame to move upward, so that the guide frame will move back and forth up and down. The up and down reciprocating movement of the guide frame will continuously turn the lower layer of slurry upward, so that the slurry can fully contact the arc magnet frame, thereby increasing the adsorption efficiency of the arc magnet frame, and then improving the magnetic separation efficiency.

The arc-shaped magnet frame 7 is used to screen the iron ore in the slurry. The partition plate 71 is fixedly connected inside the magnetic separation box 1, and the partition plate 71 is located between the drop chute on the magnetic separation box 1 and the hollow roller 6. A scraper frame 72 is fixedly connected to the top of the magnetic separation box 1, and the scraper frame 72 is used to scrape the iron ore on the surface of the hollow roller 6. The scraper frame 72 is located above the partition plate 71, and the scraper frame 72 is in contact with the hollow roller 6.

[0021] At first, the worker starts the motor 5, and the output shaft of the motor 5 drives the hollow roller 6 to rotate. At the same time, the worker pours the slurry onto the hollow roller 6 through the feeding frame 3. The slurry flows downward along the arc surface of the hollow roller 6, and the slurry falls into the magnetic separation box 1 through the arc surface of the hollow roller 6. The rotation of the hollow roller 6 drives the arc magnet frame 7 to rotate. The arc magnet frame 7 absorbs the iron ore in the slurry during the rotation, so that a large amount of iron ore adheres to the surface of the hollow roller 6. The hollow roller 6 drives the arc magnet frame 7 and the absorbed iron ore to continue to rotate, and the iron ore on the hollow roller 6 is scraped by the scraper frame 72 until the iron ore falls from the hollow roller 6, and the iron ore slides along the inclined surface of the partition plate 71 into the blanking chute of the magnetic separation box 1, and the iron ore is discharged through the discharging frame 2, and this reciprocating process is used to quickly screen out the iron ore in the slurry.

[0023] When the hollow roller 6 rotates, it will drive the two cams 11 to rotate. The rotation of the two cams 11 will drive the guide frame 9 to move downward. The return spring 10 drives the guide frame 9 to move upward, so that the guide frame 9 moves back and forth up and down. The up and down reciprocating movement of the guide frame 9 will continuously turn the lower layer of slurry upward, so that the slurry can fully contact the arc magnet frame 7, thereby increasing the adsorption efficiency of the arc magnet frame 7, and then improving the magnetic separation efficiency.

[0025] When the guide rack 9 moves up and down reciprocatingly, the guide rack 9 will drive the three guide rods 14 to move up and down reciprocatingly. The up and down reciprocating movement of the three guide rods 14 will respectively drive the three threaded rods 12 and the three stirring plates 13 to rotate. The rotation of the three stirring plates 13 will stir the slurry in the magnetic separation box 1, so that the iron ore can be more fully in contact with the arc magnet rack 7, thereby further improving the magnetic separation efficiency.
