Technical Field
[0001] The invention relates to the technical field of iron powder calcium reduction, in particular to special equipment for reducing calcium of reduced iron powder for new energy batteries. Background Art
[0002] Reduced iron powder is obtained by reducing iron-containing compounds (such as iron oxide) to remove oxygen. Reduced iron powder for new energy batteries is a specialized iron powder specifically designed for the manufacturing of new energy battery components. This powder is optimized for purity, particle size, and shape, specifically targeting the performance requirements and production processes of new energy batteries. During the processing of reduced iron powder for new energy batteries, it is necessary to separate the reduced iron powder from calcium impurities, typically achieved through magnetic separation.
[0003] Traditional magnetic separators for reducing calcium from reduced iron powder used in batteries typically use scrapers to scrape the magnetic separation drum when collecting the iron powder.

[0008] As a further solution of the present invention: the angle adjustment structure includes a driven gear, a fixed box, a second motor, a second threaded rod, a second guide rod, a second threaded sleeve and an active rack, one end of the second rotating shaft passes through the vertical plate and is fixedly connected to the driven gear, one end of a vertical plate is fixedly connected to the fixed box, and a second motor is installed inside the fixed box, and the bottom end of the fixed box is rotatably connected to the second threaded rod, and the top end of the second threaded rod passes through the inside of the fixed box and is fixedly connected to the output end of the second motor.
[0009] As a further solution of the present invention: the bottom end of the fixed box is fixedly connected to a second guide rod, and the second threaded rod is threadedly connected to a second threaded sleeve, and one end of the second threaded sleeve is fixedly connected to a driving rack, and the driving rack is meshed with the driven gear.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This device completes the dredging operation of preventing the calcium discharge outlet by setting up a dredging structure. By driving the first threaded rod to rotate, the two first threaded sleeves and the first movable block at the bottom end thereof are driven to move. With the help of the mutual cooperation of the first movable block, the linkage rod and the second movable block, the connecting frame and the top block are driven to move up and down. The top block is located directly below the calcium discharge outlet. Through the up and down movement of the top block, the calcium impurities that may accumulate at the calcium discharge outlet can be impacted and squeezed, thereby preventing the calcium discharge outlet from being blocked, ensuring that the calcium impurities can be discharged smoothly, ensuring the uninterrupted calcium reduction process, and reducing the downtime caused by the blockage of the calcium discharge outlet; 2. This device adjusts the angle of the scraper plate by setting an angle adjustment structure. The scraper plate is used to scrape the iron powder on the magnetic separation drum, effectively guiding the iron powder to fall into the collection box. Compared with the natural falling method of iron powder, the possibility of iron powder residue is greatly reduced, ensuring that more iron powder can be collected in a timely and effective manner. When the angle of the scraper plate needs to be adjusted, the second motor is started to drive the second threaded rod to rotate, thereby driving the second threaded sleeve and the active rack to move. With the help of the active rack and the driven gear meshing connection, the scraper plate is driven to rotate around the second rotating shaft to achieve the adjustment of the scraper plate angle, so that the scraper plate and the magnetic separation drum maintain a suitable contact pressure. It will not cause wear to the surface of the magnetic separation drum due to excessive pressure, affecting its magnetism and service life, nor will it cause incomplete scraping of iron powder due to too little pressure. 3. This device effectively enhances the cleaning effect of the device by setting up an auxiliary unloading structure. When the scraper plate scrapes the iron powder on the magnetic separation drum, the telescopic hose can be connected to the external pump body to transport liquid to the nozzle through the pump body. The nozzle will flush the iron powder on the magnetic separation drum to effectively remove the iron powder attached to the drum surface. Compared with simply relying on the scraper plate to scrape, the liquid flushing can penetrate into the tiny gaps between the iron powder and the drum surface to remove stubbornly adhered iron powder particles. By starting the third motor to drive the third threaded rod to rotate, the third threaded sleeve, connecting pipe and several nozzles are driven to move to increase the processing range of the nozzle, avoid cleaning dead corners, and ensure uniform cleanliness of the drum surface.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0024] Example 1
[0025] Reference Figure 1-5This embodiment provides a special device for reducing calcium of reduced iron powder for new energy batteries, including a bottom plate 1, a dredging structure, an angle adjustment structure and an auxiliary unloading structure, characterized in that the top of the bottom plate 1 is fixedly connected to a cylinder 2, a feeding bin 3 is installed on the top of the cylinder 2, a first rotating shaft 4 is rotatably connected inside the cylinder 2, and a magnetic separation roller 5 is installed on the first rotating shaft 4, and a first motor 6 is embedded on the outer wall of the cylinder 2, and the first rotating shaft 4 is fixedly connected to the output end of the first motor 6, and a calcium discharge port 7 is opened at the bottom end of the cylinder 2, and both sides of the cylinder 2 A dredging structure is provided on the wall, an iron powder collecting groove 38 is opened on one side of the cylinder 2, a collecting box 17 is fixedly connected to the top of the bottom plate 1 and located at the iron powder collecting groove 38, and two vertical plates 18 are fixedly connected to the top of the collecting box 17, a second rotating shaft 19 is rotatably connected between the two vertical plates 18, and a scraper plate 20 is fixedly connected to the second rotating shaft 19, and the scraper plate 20 is in contact with the outer surface of the magnetic separation drum 5 and an angle adjustment structure is provided on the outer wall of one vertical plate 18, and an auxiliary unloading structure is provided between the two vertical plates 18 and above the scraper plate 20.
[0026] The dredging structure includes a first threaded rod 8, a first guide rod 10, a first threaded sleeve 11, a first movable block 12, a linkage rod 13, a second movable block 14 and a connecting frame 15. The first threaded rod 8 is rotatably connected to both outer side walls of the cylinder 2, and the threads of the two first threaded rods 8 are opposite, and the first guide rod 10 is fixedly connected to both outer side walls of the cylinder 2, and the first threaded sleeve 11 is threadedly connected to the first threaded rod 8, and the bottom end of the first threaded sleeve 11 is fixedly connected to the first movable block 12.
[0027] The first movable block 12 is rotatably connected to a linkage rod 13, and the linkage rod 13 is rotatably connected to a second movable block 14 at one end away from the first movable block 12. The bottom end of the second movable block 14 is fixedly connected to a connecting frame 15, and the top ends of the two connecting frames 15 are fixedly connected to a top block 16, and the top block 16 is located directly below the calcium discharge outlet 7.
[0028] When this embodiment is in use, the first motor 6 is started first, and the output end of the first motor 6 drives the first rotating shaft 4 to rotate, so that the magnetic separation drum 5 installed on the first rotating shaft 4 rotates inside the cylinder 2, and then the reduced iron powder for the new energy battery to be processed is placed in the feed bin 3 and fed into the cylinder 2. Since the reduced iron powder and calcium impurities have different magnetic properties, the reduced iron powder will be adsorbed on the surface of the magnetic separation drum 5 under the action of the magnetic field generated by the magnetic separation drum 5. As the magnetic separation drum 5 rotates, when the part adsorbed with the reduced iron powder rotates to the iron powder collecting trough 38 position on one side of the cylinder 2, the reduced iron powder will fall into the iron powder collecting trough 38 due to the loss of the adsorption effect of the magnetic field, and then enter the collection box 17 for collection, and the calcium impurities will be discharged from the calcium discharge port 7 at the bottom end of the cylinder 2 under the action of gravity. During the operation of the equipment, in order to prevent the calcium discharge port 7 from being blocked, the calcium discharge port 7 needs to be unblocked, and the first threaded rod 8 is driven to rotate. The first threaded sleeve 11 on the first threaded rod 8 will be at the first Under the restriction of a guide rod 10, it moves along the axial direction of the first threaded rod 8. Since the thread directions of the two first threaded rods 8 are opposite, the two first threaded sleeves 11 will move in opposite directions, and the first movable block 12 fixedly connected to the bottom end of the first threaded sleeve 11 will move with the movement of the first threaded sleeve 11. The first movable block 12 is rotatably connected to the second movable block 14 through the linkage rod 13. In this way, the movement of the first movable block 12 will drive the second movable block 14 to move through the linkage rod 13, and the connecting frame 15 fixedly connected to the bottom end of the second movable block 14 will move up and down with the movement of the second movable block 14. The top block 16 fixedly connected to the top of the connecting frame 15 will also move up and down accordingly. The top block 16 is located directly below the calcium discharge outlet 7. Through the up and down movement of the top block 16, the calcium impurities that may accumulate at the calcium discharge outlet 7 can be impacted and squeezed, thereby preventing the calcium discharge outlet 7 from being blocked, ensuring that the calcium impurities can be discharged smoothly, ensuring the uninterrupted calcium reduction process, and reducing the downtime caused by blockage of the calcium discharge outlet 7.
[0029] Example 2
[0030] Reference Figure 1-8 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that the angle adjustment structure includes a driven gear 21, a fixed box 22, a second motor 23, a second threaded rod 24, a second guide rod 25, a second threaded sleeve 26 and an active rack 27, one end of the second rotating shaft 19 passes through the vertical plate 18 and is fixedly connected to the driven gear 21, one end of a vertical plate 18 is fixedly connected to the fixed box 22, and a second motor 23 is installed inside the fixed box 22, and the bottom end of the fixed box 22 is rotatably connected to the second threaded rod 24, and the top end of the second threaded rod 24 passes through the interior of the fixed box 22 and is fixedly connected to the output end of the second motor 23.
[0031] The bottom end of the fixed box 22 is fixedly connected to a second guide rod 25 , and the second threaded rod 24 is threadedly connected to a second threaded sleeve 26 , and one end of the second threaded sleeve 26 is fixedly connected to a driving rack 27 , and the driving rack 27 is meshed with the driven gear 21 .
[0032] When the present embodiment is in use, the scraper plate 20 is used to scrape off the iron powder on the magnetic separation drum 5, thereby guiding the iron powder to fall into the collection box 17. Compared with the natural falling of the iron powder, the possibility of iron powder residue is greatly reduced, ensuring that more iron powder can be collected in a timely and effective manner. When it is necessary to adjust the angle of the scraper plate 20, the second motor 23 is started, and the second motor 23 drives the second threaded rod 24 to rotate. The second threaded sleeve 26 threadedly connected to the second threaded rod 24 will move along the axial direction of the second threaded rod 24 under the restriction of the second guide rod 25. The active rack 27 fixedly connected to one end of the second threaded sleeve 26 will move with the movement of the second threaded sleeve 26. The active rack 27 is meshed with the driven gear 21, so the movement of the active rack 27 will drive the driven gear 21 to rotate, thereby rotating the second rotating shaft 19, and the scraper plate 20 fixed on the second rotating shaft 19 will rotate around the second rotating shaft 19, thereby adjusting the angle of the scraper plate 20 to better adapt to different iron powder collection conditions and improve the iron powder collection efficiency. By reasonably adjusting the angle of the scraper plate 20, the scraper plate and the magnetic separation drum 5 can maintain a suitable contact pressure, which will neither cause wear to the surface of the magnetic separation drum 5 due to excessive pressure, affecting its magnetism and service life; nor will the iron powder be incompletely scraped off due to too little pressure.
[0033] Example 3
[0034] Reference Figure 1-8 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that the auxiliary blanking structure includes a third threaded rod 28, a third guide rod 29, a third threaded sleeve 34, a connecting pipe 35, a nozzle 36 and a telescopic hose 37. The third threaded rod 28 is rotatably connected between the two vertical plates 18, and the third guide rod 29 is fixedly connected between the two vertical plates 18. The third threaded sleeve 34 is threadedly connected to the third threaded rod 28, and the third threaded sleeve 34 is fixedly connected to one end of the barrel 2 with a connecting pipe 35, a plurality of nozzles 36 are installed on the connecting pipe 35, and the top of the connecting pipe 35 is connected to the telescopic hose 37.
[0035] One end of a vertical plate 18 is fixedly connected to a mounting box 32 , and a third motor 33 is installed inside the mounting box 32 . One end of the third threaded rod 28 passes through the mounting box 32 and is fixedly connected to the output end of the third motor 33 .

[0037] When the present embodiment is in use, when the scraper plate 20 is scraping the iron powder on the magnetic separation drum 5, the telescopic hose 37 connected to the top of the connecting pipe 35 can be connected to the external pump body, and liquid is transported to the nozzle 36 through the pump body and the telescopic hose 37. The nozzle 36 will flush the iron powder on the magnetic separation drum 5 to effectively remove the iron powder attached to the surface of the drum. Compared with simply relying on the scraper plate 20 for scraping, the liquid flushing can penetrate into the fine gaps between the iron powder and the drum surface, remove stubbornly adhered iron powder particles, and avoid the residual iron powder affecting the magnetic field performance and subsequent work efficiency of the magnetic separation drum 5. During this process, the third motor 33 is started, and the third motor 33 drives the third threaded rod 28 to rotate. The third threaded sleeve 34 will be restricted by the third guide rod 29 and rotate along the third As the threaded rod 28 moves in the axial direction, the connecting pipe 35 fixedly connected to the third threaded sleeve 34 near one end of the cylinder 2 will move with the movement of the third threaded sleeve 34, and the several nozzles 36 installed on the connecting pipe 35 will also move accordingly, to increase the processing range of the nozzle 36, avoid cleaning dead corners, and ensure uniform cleanliness of the drum surface. When the auxiliary unloading structure is working, that is, the third threaded rod 28 rotates, the first threaded rod 8 will be driven to rotate through the transmission of the first synchronous wheel 9, the synchronous belt 31 and the second synchronous wheel 30, so that the two threaded rods work synchronously. Such a collaborative working design can ensure that while the calcium discharge outlet 7 is unblocked, the iron powder in the collection box 17 is assisted in unloading operations, thereby improving the overall operating efficiency and working effect of the equipment.
