Description

Technical Field

[0001] This utility model relates to the field of magnetic separator technology, specifically a multi-roller magnetic separator for purifying bauxite powder. Background Technology

[0002] Bauxite, also known as alumina or aluminum ore, is mainly composed of hydrated alumina containing impurities. It has a wide range of applications and is insoluble in water but soluble in sulfuric acid and sodium hydroxide solutions. During production, bauxite needs to be crushed. Since bauxite is generally formed by chemical weathering or exogenous processes, it is rarely a pure mineral and always contains some metallic impurities. Therefore, bauxite typically requires magnetic separation for purification.

[0003] Currently, in some existing magnetic separators, the magnetic rollers are located inside the device. When maintaining and servicing the device, it is necessary to clean the surface of the magnetic rollers and disassemble the outer casing of the magnetic separator, which is inconvenient. At the same time, bauxite powder contains some large particles, which will fall off due to gravity, thus affecting the normal magnetic separation of bauxite powder. Based on this, a multi-roller magnetic separator for purifying bauxite powder is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-roller magnetic separator for purifying bauxite powder, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-roller magnetic separator for purifying bauxite powder, comprising a shell, wherein a material chamber and a sorting chamber are arranged sequentially from top to bottom on the shell, a feeding assembly is installed inside the material chamber, a screen is movably installed inside the sorting chamber below the feeding assembly, guide plates are installed on both sides inside the sorting chamber below the screen, a magnetic roller is rotatably installed inside the sorting chamber below the two guide plates, a scraper is installed at one end inside the sorting chamber on one side of the magnetic roller, and a cleaning assembly is rotatably connected inside the sorting chamber on the other side of the magnetic roller.

[0006] Preferably, the feeding assembly includes a drive motor, a rotating rod, and a feeding plate. The material cavity is bucket-shaped. The drive motor is installed at the front end of the outer shell in front of the material cavity. The rotating rod is installed inside the material cavity at the output end of the drive motor. Several feeding plates are installed in a circumferential array on the surface of the rotating rod, and a material groove is formed between two adjacent feeding plates.

[0007] Preferably, a vibration motor is installed on the outer shell surface in front of the screen, a notch is provided at one end of the outer shell on one side of the screen, and a material box is placed at one end of the outer shell below the notch.

[0008] Preferably, the cleaning assembly includes a rotating shaft, a connecting frame, a mounting plate, a cleaning brush, and a cleaning roller.

The connecting frame is symmetrically mounted above and below the surface of the rotating shaft. Mounting plates are movably mounted on each connecting frame. The cleaning brush and cleaning roller are respectively mounted on the two mounting plates.

[0009] Preferably, connecting rods are installed at both the front and rear ends of one end of the connecting frame through through holes, the mounting plate is installed at one end of the two connecting rods, and elastic springs are installed on the surface of the connecting rods between the mounting plate and the connecting frame.

[0010] Preferably, the front and rear ends of the rotating shaft extend to the outside of the outer casing through round holes.

[0021] like Figures 1 to 4 As shown, the multi-roller magnetic separator for bauxite powder purification in this embodiment includes a housing 1. From top to bottom, the housing 1 is provided with a material chamber 2 and a sorting chamber 3. A feeding assembly is installed inside the material chamber 2 to control the feeding speed of the bauxite powder. A screen 5 is movably installed inside the sorting chamber 3 below the feeding assembly. The screen 5 is used to screen large particles in the bauxite powder, preventing them from falling directly. Guide plates 6 are installed on both sides inside the sorting chamber 3 below the screen 5 to guide the bauxite powder falling from the screen 5. The magnetic separator 7 is rotatably installed inside the sorting chamber 3 between the two guide plates 6 to achieve contact between the bauxite powder and the magnetic separator 7. The magnetic separator 7 has a certain magnetism and is used to attract metal impurities in the bauxite powder. The magnetic separator 7 can rotate under the drive of the power device. A scraper 8 is installed at one end of the sorting chamber 3 on one side of the magnetic separator 7. The scraper 8 is used to scrape off the metal impurities on the surface of the magnetic separator 7. A cleaning component is rotatably connected inside the sorting chamber 3 on the other side of the magnetic separator 7. The cleaning component is used to clean the surface of the magnetic separator 7.

[0022] Specifically, the feeding assembly includes a drive motor 401, a rotating rod 402, and a feeding plate 403. The feeding chamber 2 is bucket-shaped. The drive motor 401 is installed at the front end of the outer shell 1 in front of the feeding chamber 2. The rotating rod 402 is installed inside the feeding chamber 2 at the output end of the drive motor 401. Several feeding plates 403 are installed in a circumferential array on the surface of the rotating rod 402. A feeding trough 10 is formed between two adjacent feeding plates 403. The drive motor 401 drives the rotating rod 402 and the feeding plates 403 to rotate, and the bauxite powder enters the feeding trough 10. The feeding is evenly distributed as the feeding plates 403 rotate, avoiding excessive bauxite powder from falling directly.

[0023] Furthermore, a vibration motor 11 is installed on the surface of the outer shell 1 in front of the screen 5. A notch 12 is provided at one end of the outer shell 1 on one side of the screen 5. A material box 13 is placed at one end of the outer shell 1 below the notch 12. The screen 5 is vibrated by the vibration motor 11 to facilitate the screening of bauxite powder. Bauxite powder that does not pass through the screen 5 falls into the material box 13 through the notch 12, avoiding large particles of bauxite powder from falling directly and affecting the normal removal of metal impurities from the bauxite powder.

[0024] Furthermore, the cleaning assembly includes a rotating shaft 901, a connecting frame 902, a mounting plate 903, a cleaning brush 904, and a cleaning roller 905. The rotating shaft 901 is rotatably connected inside the sorting chamber 3 on the other side of the magnetic separator 7. The connecting frame 902 is symmetrically mounted above and below the surface of the rotating shaft 901. Mounting plates 903 are movably mounted on the connecting frame 902. The cleaning brush 904 and the cleaning roller 905 are respectively mounted on the two mounting plates 903. By rotating the rotating shaft 901, the connecting frame 902 and the mounting plate 903 are rotated, which can bring the cleaning brush 904 or the cleaning roller 905 into contact with the magnetic separator 7. The cleaning brush 904 and the cleaning roller 905 can be used in sequence. The cleaning brush 904 can brush the surface of the magnetic separator 7, and the cleaning roller 905 can wipe the surface of the magnetic separator 7, which facilitates the cleaning of the surface of the magnetic separator 7.

[0025] Furthermore, connecting rods 14 are installed at both the front and rear ends of one end of the connecting frame 902 through through holes. The mounting plate 903 is installed at one end of the two connecting rods 14. Elastic springs 15 are installed on the surface of the connecting rods 14 between the mounting plate 903 and the connecting frame 902. By using the elastic springs 15 to support the mounting plate 903, it is easy to maintain a certain pressure when the cleaning brush 904 and the cleaning roller 905 come into contact with the magnetic separation roller 7, so as to ensure effective cleaning.

[0026] Furthermore, the front and rear ends of the rotating shaft 901 extend to the outside of the outer casing 1 through round holes. Square blocks 16 are installed at both ends of the rotating shaft 901, and handles 17 are installed at one end of each square block 16. Fixed blocks 18 are slidably connected to the front and rear ends of the outer casing 1 on one side of the square block 16. Fixed grooves 19 are provided on the fixed blocks 18 near the square blocks 16. By rotating the rotating shaft 901, the cleaning brush 904 or cleaning roller 905 is brought into contact with the magnetic separation roller 7. Then, the fixed blocks 18 are moved so that the square blocks 16 are located inside the fixed grooves 19, effectively preventing the rotating shaft 901 from rotating accidentally. The fixed blocks 18 move horizontally by means of sliding grooves and sliders, and the square blocks 16 are cubes.

[0027] The usage method of this embodiment is as follows: When using this multi-roller magnetic separator for bauxite powder purification, the bauxite powder to be magnetically separated is added into the material chamber 2. The drive motor 401 drives the rotating rod 402 and the feeding plate 403 to rotate, and the bauxite powder enters the material trough 10. As the feeding plate 403 rotates, the powder is fed evenly, and the falling bauxite powder falls onto the screen 5. The vibration motor 11 drives the screen 5 to vibrate. The bauxite powder passing through the screen 5 falls onto the magnetic separation roller 7 through the guide plate 6. The magnetic separation roller 7 adsorbs the metal impurities in the bauxite powder, and the bauxite powder will fall directly off. As the magnetic separation roller 7 rotates, the scraper 8 scrapes off the metal impurities on the surface of the magnetic separation roller 7. The bauxite powder particles that have not passed through the screen 5 are removed. When particles fall into the material box 13, during the screening of metal impurities in bauxite powder, the cleaning brush 904 and cleaning roller 905 are in a vertical position. During maintenance and upkeep, the handle 17 is manually turned, which drives the rotating shaft 901 to rotate at a certain angle through the square block 16. At the same time, under the action of the spring spring 15, the cleaning brush 904 contacts the magnetic separator 7 with a certain pressure. Then, the fixed block 18 is moved so that the square block 16 is located inside the fixed groove 19, effectively preventing the rotating shaft 901 from rotating accidentally. This allows the cleaning brush 904 to brush the surface of the magnetic separator 7. The cleaning roller 905 is used in the same way as the cleaning brush 904, which can effectively clean the magnetic separator 7 and facilitate the maintenance and upkeep of the magnetic separator.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
