Technical Field

[0001] This utility model relates to the field of alumina micro powder technology, specifically an alumina micro powder processing equipment with magnetic separation for impurity removal. Background Technology

[0002] During the processing of alumina micro powder, impurities are often introduced, which can affect the purity and performance of the alumina micro powder, thus requiring impurity removal treatment. Currently, magnetic separation is a commonly used impurity removal method, which uses the magnetism of a magnet to adsorb impurities, thereby achieving the purpose of impurity removal.

[0003] In the prior art, the authorized announcement number CN222197323U discloses a magnetic separation device for diamond micro powder with impurity removal, which includes a magnetic separation box. A removal plate is rotatably connected to one side of the magnetic separation box. Two L-shaped guide rails are fixedly connected to the side of the removal plate away from the magnetic separation box. A mating panel is slidably connected between the two L-shaped guide rails. A limiting crossbar is provided between the bottom ends of the two L-shaped guide rails. Magnets are equidistantly bonded to the side of the mating panel near the removal plate. Positioning components are provided on both sides of the removal plate. A storage hopper and a displacement component for driving the storage hopper to move back and forth are provided on the top of the magnetic separation box.

[0004] In the above scheme, although the device can achieve the function of removing impurities to a certain extent, it has some drawbacks in actual use: when the mating panel is pulled up, the magnet also moves up, and the impurities are attracted and slide up on the impurity removal plate, so the impurities cannot be collected well. Utility Model Content

[0005] The purpose of this invention is to provide an alumina micro powder processing device with magnetic separation for impurity removal, in order to solve the problem in the prior art that when the matching panel is pulled up, the magnet also moves up, and the impurities are attracted and slide up on the impurity removal plate, thus making it impossible to collect the impurities effectively.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an alumina micro powder processing device with magnetic separation for impurity removal, comprising a magnetic separator, an impurity removal plate fixedly connected inside the magnetic separator, a scraper provided on one side of the impurity removal plate, an internally threaded sleeve fixedly connected to the top of the scraper, a threaded rod internally threadedly connected to the internally threaded sleeve, an installation plate rotatably connected to the outside of the threaded rod, a forward and reverse motor fixedly connected to the top of the installation plate, the output end of the forward and reverse motor fixedly connected to the threaded rod, a support member provided on the outside of the installation plate, a telescopic rod provided between the installation plate and the scraper, the two ends of the telescopic rod being fixedly connected to the installation plate and the scraper respectively, a magnet plate provided at the bottom of the impurity removal plate, a lifting plate fixedly connected to the bottom of the magnet plate, a lifting structure provided between the lifting plate and the installation plate, and a material storage structure provided at the top of the magnetic separator.

[0007] Preferably, a frame is fixedly connected to the outside of the magnetic separator, and a collection box is provided on the top of the frame, with the collection box located at the outlet of the magnetic separator.

[0008] Preferably, the support includes two support frames, one end of each support frame is fixedly connected to the mounting plate, and the other end of each support frame is fixedly connected to the magnetic separator. The two support frames provide fixed support for the mounting plate.

[0009] Preferably, the lifting structure includes a second internally threaded sleeve, which is fixedly connected to the bottom of the lifting plate. A second threaded rod is threadedly connected inside the second internally threaded sleeve. One end of the second threaded rod passes through the mounting plate and is rotatably connected to the mounting plate. Gears are fixedly connected to the outer sides of both the second threaded rod and the first threaded rod, and the two gears mesh with each other.

[0010] Preferably, the lifting structure further includes two L-shaped slide bars, both of which are fixedly connected to the bottom of the magnetic separator. One end of each of the two L-shaped slide bars passes through the lifting plate and is slidably connected to the lifting plate. One end of each of the two L-shaped slide bars is fixedly connected to the mounting plate. The two L-shaped slide bars provide sliding support for the lifting plate.

[0011] Preferably, the storage structure includes a storage hopper, which is located at the top inlet of the magnetic separator. A hydraulic cylinder is provided on one side of the storage hopper, and an L-shaped support is fixedly connected to the outside of the hydraulic cylinder. One end of the L-shaped support is fixedly connected to the storage hopper, and an L-shaped plate is fixedly connected to one end of the hydraulic cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application uses a threaded rod two to be threadedly connected to an internal threaded sleeve two. Under the limiting action of the two L-shaped sliding rods on the lifting plate, the internal threaded sleeve two drives the magnetic plate to tilt upward through the lifting plate. Therefore, this structure realizes that when the magnetic plate tilts upward, the scraper can tilt downward to scrape off the impurities on the impurity removal plate, avoiding the situation where the impurities slide on the surface of the impurity removal plate as the magnetic plate moves. When the scraper pushes to the bottom of the impurity removal plate, the impurities are discharged through the magnetic separator outlet. Then, the impurity collection frame is placed on the frame, which is the original position of the collection box, so that the impurities can be collected.

[0015] 2. This application drives the reciprocating screw to rotate through the output end of the drive motor. The reciprocating screw is threadedly connected to the connecting block. Under the limiting action of the square rod on the connecting block, the connecting block can drive the storage hopper to move back and forth. Therefore, the micro powder can fall evenly onto the impurity removal plate. The iron-containing impurities in the micro powder are adsorbed onto the surface of the impurity removal plate by the magnetic plate, and the micro powder falls into the collection box through the magnetic separator outlet for collection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for an alumina micro powder processing device with magnetic separation for impurity removal. It includes a magnetic separator 2, a frame 1 fixedly connected to the outside of the magnetic separator 2, a collection box 3 located at the top of the frame 1, and the collection box 3 positioned at the outlet of the magnetic separator 2. An impurity removal plate 4 is fixedly connected inside the magnetic separator 2, a scraper 5 is located on one side of the scraper 4, and an internally threaded sleeve 6 is fixedly connected to the top of the scraper 5. A threaded rod 7 is threadedly connected inside the internally threaded sleeve 6, and a mounting plate 9 is rotatably connected to the outside of the threaded rod 7. A forward and reverse motor 700 is fixedly connected to the top of the mounting plate 9. The output end of the reverse motor 700 is fixedly connected to the threaded rod 7. The outer side of the mounting plate 9 is provided with a support member, which includes two support frames 10. One end of each support frame 10 is fixedly connected to the mounting plate 9, and the other end of each support frame 10 is fixedly connected to the magnetic separator 2. A telescopic rod 8 is provided between the mounting plate 9 and the scraper 5. The two ends of the telescopic rod 8 are fixedly connected to the mounting plate 9 and the scraper 5, respectively. A magnet plate 11 is provided at the bottom of the impurity removal plate 4. A lifting plate 12 is fixedly connected to the bottom of the magnet plate 11. A lifting structure is provided between the lifting plate 12 and the mounting plate 9. A material storage structure is provided at the top of the magnetic separator 2.

[0023] The lifting structure includes an internally threaded sleeve 14, which is fixedly connected to the bottom of the lifting plate 12. A threaded rod 16 is threadedly connected inside the internally threaded sleeve 14. One end of the threaded rod 16 passes through the mounting plate 9 and is rotatably connected to the mounting plate 9. Gears 17 are fixedly connected to the outer sides of both the threaded rod 16 and the threaded rod 17. The two gears 17 mesh with each other. The lifting structure also includes two L-shaped slide rods 13, which are fixedly connected to the bottom of the magnetic separator 2. One end of each L-shaped slide rod 13 passes through the lifting plate 12 and is slidably connected to the lifting plate 12. One end of each L-shaped slide rod 13 is fixedly connected to the mounting plate 9.

[0024] Specifically, starting the forward / reverse motor 700 (the specific model of the forward / reverse motor 700 is not limited, but depends on the compatible equipment) causes the output end of the forward / reverse motor 700 to drive the threaded rod 7 to rotate on the mounting plate 9. The threaded rod 7 is threadedly connected to the internal threaded sleeve 6. Under the limiting action of the telescopic rod 8 on the scraper 5, the scraper 5 tilts and moves downward. At the same time, the rotation of the threaded rod 7 drives one of the gears 17 to rotate. One gear 17 meshes with another gear 17, which drives the threaded rod 16 to rotate on the mounting plate 9. The threaded rod 16 is threadedly connected to the internal threaded sleeve 14. Next, under the limiting action of the two L-shaped sliding rods 13 on the lifting plate 12, the internal threaded sleeve 14 drives the magnetic plate 11 to tilt upward through the lifting plate 12. Therefore, this structure realizes that when the magnetic plate 11 tilts upward, the scraper 5 can tilt downward to scrape off the impurities on the impurity removal plate 4, avoiding the situation where the impurities slide on the surface of the impurity removal plate 4 as the magnetic plate 11 moves. When the scraper 5 is pushed to the bottom of the impurity removal plate 4, the impurities are discharged through the outlet of the magnetic separator 2. Then, the impurity collection frame is placed on the frame 1, which is the original position of the collection box 3, so that the impurities can be collected.

[0025] Example: Figure 1 , Figure 2 and Figure 4 As shown, the storage structure includes a storage hopper 18, which is located at the top inlet of the magnetic separator 2. A hydraulic cylinder 20 is provided on one side of the storage hopper 18. An L-shaped support 21 is fixedly connected to the outside of the hydraulic cylinder 20. One end of the L-shaped support 21 is fixedly connected to the storage hopper 18, and an L-shaped plate 19 is fixedly connected to one end of the hydraulic cylinder 20. One end of the L-shaped plate 19 passes through the outside of the storage hopper 18 and extends into the inside of the storage hopper 18. The L-shaped plate 19 is slidably connected to the storage hopper 18. The storage structure also includes... Connecting block 22 is fixedly connected to the outside of storage hopper 18. A reciprocating screw 23 is threadedly connected to the inside of connecting block 22. Fixed plates 24 are rotatably connected to both ends of the reciprocating screw 23. Both fixed plates 24 are fixedly connected to magnetic separator 2. A drive motor 26 is fixedly connected to the outside of magnetic separator 2. The output end of drive motor 26 is fixedly connected to reciprocating screw 23. A square rod 25 is fixedly connected between the two fixed plates 24. Connecting block 22 is slidably connected to the outside of square rod 25.

[0026] Specifically, the hydraulic cylinder 20 is activated, which drives the L-shaped plate 19 to move, thereby adjusting the position of the L-shaped plate 19 and the size of the opening of the outlet of the storage hopper 18, thus achieving the speed of micro powder feeding.

[0027] In addition, the drive motor 26 is started. The specific model of the drive motor 26 is not limited, but depends on the compatible equipment. The output end of the drive motor 26 drives the reciprocating screw 23 to rotate. The reciprocating screw 23 is threadedly connected to the connecting block 22. Under the limiting action of the square rod 25 on the connecting block 22, the connecting block 22 can drive the storage hopper 18 to move back and forth. Therefore, the micro powder can fall evenly onto the impurity removal plate 4. The iron-containing impurities in the micro powder are adsorbed onto the surface of the impurity removal plate 4 by the magnetic plate 11, and the micro powder falls into the collection box 3 through the outlet of the magnetic separator 2 for collection.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
