Description

Technical Field

[0001] This utility model relates to the field of magnetic separation technology, and in particular to a magnetic separation and iron removal device for lithium manganese oxide raw materials. Background Technology

[0002] Currently, lithium manganese oxide is one of the more promising lithium-ion cathode materials. Lithium manganese oxide has advantages such as abundant resources, low cost, no pollution, good safety, and good rate performance. However, the iron contained in its raw materials can cause the battery to discharge quickly and affect the quality of the battery. It is necessary to remove iron from the raw materials. Chinese utility model patent, authorized announcement number "CN217042987U", discloses a magnetic separation iron removal device for lithium manganese oxide powder. By setting a current collector ring, the iron removal mechanism can rotate and be energized at the same time. Under the drive of the drive mechanism, the iron removal mechanism can stir the powder. At the same time, the electromagnetic chuck can adsorb iron filings, resulting in high iron removal efficiency.

[0003] In the above-mentioned technical solution, the magnetic separation and iron removal device for lithium manganese oxide raw materials operates in batches. Because it processes materials in batches, the equipment needs to be stopped after each processing to load and unload the raw materials. During this period, the equipment is in a shutdown state and cannot continuously process raw materials, resulting in low overall processing efficiency and difficulty in meeting the needs of large-scale industrial production. Therefore, we propose a magnetic separation and iron removal device for lithium manganese oxide raw materials. Utility Model Content

[0026] Please see Figure 1-4 This utility model provides a technical solution: a magnetic separation and iron removal device for lithium manganese oxide raw materials, comprising:

[0027] Conveyor platform 1 and conveyor mechanism 2, with conveyor mechanism 2 installed inside conveyor platform 1;

[0028] The magnetic separation and iron removal structure is located on the conveyor table 1.

[0029] The magnetic separation iron removal structure includes a magnetic separator 3, two mounting boxes 15, two conveying mechanisms 16, two rotating plates 12, and two electric telescopic rods 14. The magnetic separator 3 is fixedly connected to the top of the conveyor table 1. Two fixed plates 11 are fixedly connected to both sides of the inner wall of the magnetic separator 3. The two rotating plates 12 are rotatably connected to the opposite surfaces of the two fixed plates 11. The two mounting boxes 15 are fixedly connected to the corresponding rotating plates 12. The two conveying mechanisms 16 are installed inside the corresponding mounting boxes 15. The two electric telescopic rods 14 are rotatably connected to the inside of the magnetic separator 3. The telescopic ends of the two electric telescopic rods 14 are rotatably connected to the corresponding mounting boxes 15. Electromagnets 18 are installed inside the two mounting boxes 15. The two electromagnets 18 are located inside the corresponding conveying mechanisms 16.

[0030] The magnetic separation iron removal structure also includes two scraper blades 13, two collection boxes 4, an electromagnet 7, and a scraper blade 8. Both sides of the magnetic separator 3 are provided with mounting grooves 10 that communicate with their interiors. The two collection boxes 4 are slidably connected to the interior of the corresponding mounting grooves 10. The two mounting boxes 15 are provided with discharge ports 17 on the side near the corresponding electric telescopic rod 14. The two scraper blades 13 are fixedly connected to the interior of the corresponding discharge ports 17. The electromagnet 7 is fixedly installed inside the conveyor table 1. The electromagnet 7 is located inside the conveying mechanism 2. The scraper blade 8 is fixedly connected to the interior of the conveyor table 1. The collection box 9 is placed inside the conveyor table 1.

[0031] Both conveying mechanism 12 and the two conveying mechanisms 26 are composed of two conveying rollers, a conveyor belt and a motor. The two conveying rollers are rotatably connected inside the mounting box 15. The conveyor belt is sleeved on the outer surface of the two conveying rollers. The motor is fixedly installed on one side of the mounting box 15. The output end of the motor extends into the interior of the mounting box 15 and is fixedly connected to the corresponding conveying roller. One side of each of the two scraper blades 23 is in contact with the conveyor belt on the corresponding conveying mechanism 26. Both scraper blades 23 are located above the corresponding collection box 4. The top of scraper blade 18 is in contact with the conveyor belt on the conveying mechanism 12. Scraper blade 18 is located above the collection box 9.

[0032] Guide plates 5 are fixedly connected to both sides of the inside of the magnetic separator 3. Both guide plates 5 are located above the corresponding conveying mechanism 16. Two sealing plates 6 are fixedly connected inside the magnetic separator 3. The two sealing plates 6 are located on both sides of the two mounting boxes 15 and slide in contact with them.

[0033] Furthermore, when using the device, the raw material enters the magnetic separator 3 and falls onto the conveying mechanism 16 under the guidance of the guide plate 5. The sealing plate 6 is located on both sides of the mounting box 15 and slides in contact with it to prevent the raw material and impurities from leaking during the magnetic separation process and to ensure the sealing of the device. When the raw material falls onto the conveying mechanism 16, the electromagnet 18 is energized to generate a magnetic field, which adsorbs ferromagnetic impurities in the raw material.

[0034] When the angle of the mounting box 15 needs to be adjusted to accommodate lithium manganese oxide raw materials of different coarseness, the electric telescopic rod 14 is activated. The electric telescopic rod 14 extends and retracts, driving the mounting box 15, so that the mounting box 15 drives the rotating plate 12 to rotate within the opposite surfaces of the two fixed plates 11. This allows the conveying mechanism 16 to tilt to different degrees, thereby adjusting the included angle between the two conveying mechanisms 16. When the conveying mechanism 16 transports the adsorbed ferromagnetic impurities to the discharge port 17, the conveyor belt on the conveying mechanism 16 rotates upward. The scraper plate 13 scrapes the ferromagnetic impurities on the conveyor belt, causing them to fall through the discharge port 17 into the collection box 4 below. The collection box 4 is slidably connected in the mounting groove 10 of the magnetic separator 3 for easy removal and cleaning.

[0035] After primary magnetic separation, the lithium manganese oxide raw material falls onto the conveyor mechanism 2 and is conveyed on the conveyor table 1. When the raw material passes above the electromagnet 7, the electromagnet 7 is energized to generate a magnetic field, which adsorbs ferromagnetic impurities in the raw material. As the conveyor belt moves, the adsorbed ferromagnetic impurities are carried below the electromagnet 7. At this time, the scraper plate 8 scrapes the impurities off the conveyor belt and they fall into the collection box 9, completing the magnetic separation and iron removal.

[0036] Through continuous operation of primary and secondary magnetic separation, deep removal of ferromagnetic impurities from lithium manganese oxide raw materials is achieved. By using an adjustable-angle conveying mechanism 216, the angle between the two conveying mechanisms 216 can be adjusted, enabling the device to adapt to lithium manganese oxide raw materials of different fineness, ensuring uniform distribution of raw materials during the conveying process, and improving the magnetic separation effect. Compared with traditional batch operation, this device does not require stopping to load and unload raw materials, and can continuously process raw materials, thereby improving iron removal efficiency and raw material purity, and meeting the needs of large-scale industrial production.
