Description

Technical Field

[0001] This utility model belongs to the field of magnetic separators, specifically relating to a magnetic separator for mining processing with a sorting structure. Background Technology

[0002] During ore mining, magnetic minerals and gangue minerals often have different uses. However, during mining, some magnetic minerals are located close to gangue minerals, which can easily lead to them being mixed together. Magnetic separators are often needed during processing to achieve effective separation and improve mineral purity.

[0003] Currently, although magnetic separators can effectively separate magnetic minerals such as magnetite and hematite from gangue minerals such as quartz sand and albite, the ores often have volume differences after crushing. Different volumes of ores require different processes for mineral extraction. Mixing these ores together is also inconvenient for subsequent processing, and other devices are still needed for screening. However, existing magnetic separators only have the function of separating magnetic minerals and gangue minerals, and do not have the function of screening according to volume. It takes a lot of time to transfer the magnetic ore to other screening devices.

[0004] Therefore, in response to the problem that existing magnetic separators require a lot of time to transfer magnetic ore to other devices for screening according to size, a magnetic separator with a sorting structure for mining processing can be designed and equipped with a screening filter. Utility Model Content

[0005] To overcome the problem that existing magnetic separators require a lot of time to transfer magnetic ore to other devices for screening according to size.

[0006] The technical solution of this utility model is as follows: a magnetic separator for mining processing with a sorting structure, including a magnetic separator drum; it also includes a screening box and a screening filter screen. The magnetic separator drum is set above the ground, and a screening box with a built-in vibrating motor is set on the right side of the magnetic separator drum. A screening filter screen with a higher back and lower front is set inside the screening box. A mounting base that is close to the inner wall of the screening box is fixedly connected to the rear side of the screening filter screen. An anchoring hole is opened on the mounting base. A discharge port located in front of the screening filter screen is opened on the front side of the screening box.

[0007] Preferably, the magnetic ore is moved into the screening box through the magnetic separator, and the built-in vibration motor is started. The vibration motor drives the screening box and the internal screening screen to vibrate, so that the magnetic ore rolls along the inclined screening screen. Smaller ore passes through the screening screen and falls into the screening box, while larger ore remains above the screening screen and flows out from the discharge port along the screening screen.

[0008] Preferably, an inclined scraper with a left-high and right-low orientation is fixedly connected to the left side of the screening box, and two limiting plates that are opposite to each other and connected to the inclined scraper are fixedly connected to the top of the screening box.

[0009] Preferably, a rotating shaft is fixedly connected to the rear side of the magnetic separator, and a column installed on the ground is provided on the rear side of the magnetic separator, with the rotating shaft movably inserted into the column.

[0010] Preferably, a rotary motor is installed on the rear side of the column, and the output end of the rotary motor is fixedly connected to the rear end of the rotating shaft.

[0011] Preferably, a feed box is provided at the left end of the magnetic separator, an arc-shaped discharge chute is provided on the right side of the feed box, and a feed pipe is installed at the top of the feed box.

[0012] Preferably, a feeding pusher plate is movably connected inside the feeding box and located on the left side of the arc-shaped discharge chute, and an electric push rod is installed on the left side of the feeding box.

[0013] Preferably, the output end of the electric push rod passes through the left side plate of the feed box and is fixedly connected to the left side of the feeding push plate.

[0014] The beneficial effects of this utility model are:

[0015] By replacing the traditional magnetic ore discharge box with a screening box containing a built-in vibrating motor, and installing a screening filter with a certain inclination inside the screening box, smaller magnetic ores fall to the bottom along the screening filter during vibration, while larger magnetic ores remain on the screening filter and flow out from the discharge port along the inclination of the screening filter, thus achieving the separation of magnetic ores.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment: a magnetic separator for mining processing with a sorting structure, including a magnetic separator barrel 1; it also includes a screening box 2 and a screening filter screen 3. The magnetic separator barrel 1 is installed above the ground, and the screening box 2 with a built-in vibrating motor is installed on the right side of the magnetic separator barrel 1. The screening filter screen 3, which is higher at the back and lower at the front, is installed inside the screening box 2. The rear side of the screening filter screen 3 is fixedly connected to a mounting base 4 that is close to the inner wall of the screening box 2. Anchoring holes are opened on the mounting base 4. The front side of the screening box 2 is provided with a section located at the screening filter screen. The discharge port 5 on the front side of the magnetic separator 1 moves the magnetic ore into the screening box 2. The built-in vibrating motor is activated, causing the screening box 2 and the internal screening screen 3 to vibrate. This causes the magnetic ore to roll along the inclined screening screen 3. Smaller ore particles pass through the screening screen 3 and fall into the screening box 2, while larger particles remain above the screening screen 3 and flow out from the discharge port 5. An inclined scraper 6, with the left side higher than the right, is fixedly connected to the left side of the screening box 2. Two limiting plates 7 are fixedly connected to the top, facing each other and connected to the inclined scraper 6. The inclined scraper 6 scrapes the magnetically adsorbed ore from the outside of the magnetic separator 1 as it rotates clockwise, allowing it to fall onto the screening filter 3 inside the screening box 2. The limiting plates 7 restrict the magnetic ore scraped from the magnetic separator 1, preventing it from overflowing from the left and right sides. A rotating shaft 8 is fixedly connected to the rear of the magnetic separator 1, and a mounting plate is installed on the rear of the magnetic separator 1. The column 9 on the ground has a rotating shaft 8 that is movably inserted into it. The rotation of the rotating shaft 8 drives the magnetic separator 1 to rotate clockwise, attracting the magnetic ore in the left feed box 11 onto the magnetic separator 1. Then, it rotates to the right, and the inclined scraper 6 scrapes off the magnetic ore on the outside of the magnetic separator 1. A rotary motor 10 is installed at the rear of the column 9. The output end of the rotary motor 10 is fixedly connected to the rear end of the rotating shaft 8. The rotary motor 10 can provide power for the rotation of the magnetic separator 1, thereby realizing the clockwise rotation of the magnetic separator 1.

[0025] Please see Figures 5-6In this embodiment, a feed box 11 is provided at the left end of the magnetic separator 1, and an arc-shaped discharge chute 12 is provided on the right side of the feed box 11. A feed pipe 13 is installed at the top of the feed box 11. After the ore has undergone pre-treatment by crushing, it falls into the feed box 11 through the feed pipe 13 installed at the top of the feed box 11. The arc-shaped discharge chute 12 on the right side is an open structure, facing the outer wall of the magnetic separator 1. After the magnetic separator 1 is started, the magnetic ore is attracted and forms magnetic clusters, which roll together with the magnetic separator 1 and flow into the feed box 11. The feed pusher plate 14 is connected to the left side of the arc-shaped discharge chute 12. An electric pusher rod 15 is installed on the left side of the feed box 11. The output end of the electric pusher rod 15 passes through the left side plate of the feed box 11 and is fixedly connected to the left side of the feed pusher plate 14. When working, the electric pusher rod 15 can extend and retract its output end. The electric pusher rod 15 pushes the feed pusher plate 14 to move toward the arc-shaped discharge chute 12, concentrating the ore in the feed box 11 to the position of the arc-shaped discharge chute 12, so that the magnetic separator 1 can adsorb magnetic minerals.

[0026] When working, the workers first pass the anchor through the anchor hole opened in the mounting base 4, fix the mounting base 4 and the screening filter 3 fixedly connected to the mounting base 4 in the screening box 2, and then pass the output end of the electric push rod 15 through the hole slot on the left side of the feed box 11 and install it with the feeding push plate 14. After the installation is completed, fix the electric push rod 15 on the feed box 11, and then connect the discharge pipe of the ore pretreatment device to the feed pipe 13 of the feed box 11.

[0027] After the ore is pre-treated, it falls into the feed box 11 through the feed pipe 13. The electric push rod 15 is started, and the output end of the electric push rod 15 extends. The output end pushes the feeding push plate 14 to move to the right, moving the ore to the position of the arc-shaped discharge chute 12. The magnetic separator 1 is equipped with a permanent magnet, which generates a magnetic field and attracts the magnetic ore to the outside of the magnetic separator 1. The rotary motor 10 is started, and the rotary motor 10 drives the rotating shaft 8 and the magnetic separator 1 fixedly connected to the rotating shaft 8 to rotate clockwise together, causing the magnetic ore to rotate to the right. During the rotation, the magnetic ore touches the inclined scraper 6. The force generated by the rotation of the magnetic separator 1 and the force generated by the restriction formed by the inclined scraper 6 scrape the magnetic ore off the magnetic separator 1. The limiting plate 7 forms a block to prevent the magnetic ore from overflowing from both ends of the inclined scraper 6. Under the action of gravity, the ore falls along the inclined scraper 6 onto the screening filter screen 3 in the screening box 2.

[0028] Start the built-in vibration motor of the screening box 2. The vibration motor drives the screening box 2 and the screening screen 3 to vibrate, so that the smaller magnetic ore above passes through the screening screen 3 and falls into the screening box 2, while the larger ore remains on the screening screen 3 and flows out from the discharge port 5 along the slope of the screening screen 3.

[0029] Through the above steps, the traditional magnetic ore discharge box is replaced with a screening box 2 with a built-in vibrating motor. A screening filter 3 with a certain inclination is installed in the screening box 2. During the vibration process, smaller magnetic ores fall down along the screening filter 3, while larger magnetic ores remain on the screening filter 3 and flow out from the discharge port 5 along the inclination of the screening filter 3, thus realizing the separation of magnetic ores. This solves the problem that existing magnetic separators need to spend a lot of time transferring magnetic ores to other devices before they can be screened according to size.
