Description

Technical Field

[0002] Neodymium iron boron alloy is a rare earth permanent magnet material composed of neodymium, iron, and boron. It has an ultra-high magnetic energy product and strong magnetism, and is the most excellent permanent magnet in modern technology. It is widely used in electronic products, green energy, industrial equipment, and the medical field, and is a key material for realizing efficient energy conversion and precise control. When producing neodymium iron boron alloy, due to the large brittleness, easy oxidation of the materials, as well as the need for precision machining and surface treatment, a large amount of cutting chips and scraps will be generated during the production process. In order to improve the economy and environmental protection of production, it is necessary to recycle these wastes to reduce resource waste.

[0003] At present, the recycling of neodymium iron boron production wastes is mainly to press wastes such as cutting chips and scraps into high-density blocks through a waste briquetting device, and then reintroduce them into the smelting process to extract rare earth elements, iron, boron and other components for the production of new neodymium iron boron alloys.

[0004] The existing waste briquetting device cleans, dries, and crushes neodymium iron boron production wastes, and then compresses them into shape through an internal hydraulic press.

[0036] From Figures 1 - 10As shown in the figure, the present invention includes a production device 1 for compressing and processing waste materials from the production of neodymium-iron-boron alloys.

The bottom end of the driving member 3 passes through the top of the support plate 6 and is fixedly connected to the top of the mounting plate 2. And on the top end of the driving member 3, there is a sliding groove 8 for the limiting post 4 to move. The limiting post 4 is connected to the top end of the driving member 3 through a plurality of fixing components 9. The top end of the limiting post 4 is located inside the movable frame 5.

On both sides of the movable frame 5, there are support columns 10. On the surface of the limiting component 7, there are through holes 11 for the support columns 10 to pass through. At the ends of the two support columns 10 away from the movable frame 5, there are respectively a pushing plate 12 and a limiting block 13. On the top of the pushing plate 12, there are two limiting structures 14 for limiting the waste blocks;

[0037] The limiting structure 14 includes a connecting plate 15, a mounting rod 16, a baffle 17, a movable member, and a limiting plate 18. The connecting plate 15 is arranged in an inverted concave shape. And the two ends of the bottom of the connecting plate 15 are respectively fixedly connected to the top of the pushing plate 12 and the top of the mounting rod 16. On one side of the mounting rod 16, there is a receiving groove 19 for the movable member to move. One end of the movable member is fixedly connected to one side inside the receiving groove 19. One side of the limiting plate 18 is connected to one side of the movable member through a connecting member 21. And on one end of the mounting rod 16, there is a through groove 20 for the connecting member 21 to move. The through groove 20 is communicated with the inside of the receiving groove 19. The bottom of the baffle 17 is fixedly connected to the top of the mounting plate 2. On the side of the limiting plate 18 away from the stabilizing rod 34, there are a plurality of rollers 37. By means of the plurality of rollers 37 arranged on one side of the limiting plate 18, the friction between the limiting plate 18 and the waste block can be reduced during the movement of the limiting plate 18, thereby preventing the limiting plate 18 from driving the waste block to move during the movement;

[0038] The driving member 3 includes a motor 22, a connecting column 23 and a turntable 24. The bottom of the motor 22 is fixedly connected to the top of the mounting plate 2, the output end of the motor 22 is fixedly connected to the bottom of the connecting column 23, the top of the connecting column 23 passes through the bottom of the support plate 6 and is fixedly connected to the bottom of the turntable 24, and a slide groove 8 is provided on the top of the turntable 24 for the limit column 4 to move. The limit assembly 7 includes a connecting rod 25, a support rod 26 and a support block 27. One end of the connecting rod 25 is fixedly connected to one side of the support plate 6, and the bottom of the support rod 26 is connected to the connecting rod 25 away from the support plate 6. The top of one end is fixedly connected, the bottom of the support block 27 is fixedly connected to the top of the support rod 26, and a through hole 11 is provided on one side of the support block 27 for the support column 10 to pass through. The fixing assembly 9 includes a fixing plate 28, a connecting rod 29 and a threaded column 30. The bottom of the fixing plate 28 is fixedly connected to the top of the turntable 24, and a groove 31 is provided on one side of the fixing plate 28 for the connecting rod 25 to move. One end of the connecting rod 29 is fixedly connected to the outer side of the limiting column 4, and the end of the connecting rod 29 away from the limiting column 4 is located inside the groove 31. The bottom end of the threaded column 30 passes through the fixing plate 28. The top of the limit column 4 extends to the inside of the connecting rod 29, and the motor 22 is started. The motor 22 drives the connecting column 23 and the turntable 24 to rotate. During the rotation of the turntable 24, the limit column 4 is driven to move synchronously. Since the outer side of the limit column 4 is in contact with the inner side of the movable frame 5, the limit column 4 itself slides inside the movable frame 5 and drives the movable frame 5 to move during the process of the limit column 4 following the rotation of the turntable 24. However, because the support columns 10 arranged on both sides of the limit frame respectively pass through the through holes 11 opened on one side of the support block 27, Under the restriction of the through hole 11, the support column 10 can only translate along the through hole 11, thereby restricting the movement trajectory of the movable frame 5, preventing the movable frame 5 from rotating along the movement trajectory of the limiting column 4. During the movement of the movable frame 5, the push plate 12 will be driven to move toward the waste block, and the waste block will be pushed to move toward the side of the placement table 53 by the push plate 12. The support column 10 can be limited by the limiting block 13 set at one end of the support column 10 to prevent the support column 10 from being separated from the through hole 11 opened on one side of the fixed block.

[0039] The movable part includes a movable plate 32 and a plurality of springs 33. One side of the movable plate 32 is located inside a receiving groove 19 formed on one side of the mounting rod 16. One ends of the plurality of springs 33 are fixedly connected to the side of the movable plate 32 located inside the receiving groove 19. The ends of the springs 33 away from the movable plate 32 are fixedly connected to one side inside the receiving groove 19. The side of the movable plate 32 away from the springs 33 is inclined, and the inclined surface of the movable plate 32 is in contact with one side of the baffle 17. The connecting member 21 includes a stabilizing rod 34, a stabilizing block 35, and a fixing column 36. The stabilizing rod 34 is L-shaped, and one end of the stabilizing rod 34 is fixedly connected to one side of the limiting plate 18. The end of the stabilizing rod 34 away from the limiting plate 18 is fixedly connected to one side of the stabilizing block 35. One end of the fixing column 36 passes through one side of the stabilizing block 35 and extends into the movable plate 32. The fixing column 36 is threadedly connected to the stabilizing block 35 and the movable plate 32. By removing the fixing column 36 from the stabilizing block 35, the stabilizing rod 34 loses its limit, and by pulling the stabilizing rod 34, it can move inside the through groove 20, and the position of the limiting plate 18 is adjusted by the movement of the stabilizing rod 34;

[0040] The production equipment 1 includes a processing table 38, a hydraulic press 39, and a discharging component 40. A feeding port 41 for feeding materials is provided at the top of the processing table 38, and a crushing column 42 is provided inside the feeding port 41. A shaping cavity 43 is provided inside the processing table 38. The feeding port 41 communicates with the shaping cavity 43. The hydraulic press 39 is provided on one side of the processing table 38, and one end of the hydraulic press 39 is located inside the shaping cavity 43. An installation groove 44 is provided on one side inside the shaping cavity 43. One end of the discharging component 40 is fixedly connected to one side inside the installation groove 44, and the outer side of the discharging component 40 is in contact with the inner side of the installation groove 44. A discharging port 45 is also provided on one side inside the shaping cavity 43. A placing table 53 is provided on one side of the processing table 38, and the placing table 53 is located at the bottom of the discharging port 45. The discharging component 40 includes a telescopic cylinder 46 and a discharging plate 47. One end of the telescopic cylinder 46 is fixedly connected to one side inside the installation groove 44, and the output end of the telescopic cylinder 46 is fixedly connected to one side of the discharging plate 47. The outer side of the discharging plate 47 is in contact with the inner side of the installation groove 44. The outer side of the discharging plate 47 is in contact with the inner side of the installation groove 44, which can effectively prevent the debris of the neodymium iron boron production waste from entering the installation groove 44;

[0041] On one side of the processing table 38, there is also a loading component. The loading component includes a conveyor belt 48, a fixing strip 49, and a plurality of mounting support plates 50. The conveyor belt 48 is inclinedly installed, and the top end of the conveyor belt 48 is located at the top of the feeding port 41. A plurality of baffle plates 51 are arranged on the surface of the conveyor belt 48. One ends of the plurality of mounting support plates 50 are respectively fixedly connected to both sides of the conveyor belt 48. One ends of the plurality of mounting support plates 50 far from the conveyor belt 48 are connected to the top of the processing table 38 and the fixing strip 49 through stabilizing columns 52. The stabilizing columns 52 are threadedly connected to the mounting support plates 50, the processing table 38, and the fixing strip 49. Since the conveyor belt 48 is connected to the processing table 38 and the fixing strip 49 through the mounting support plates 50 and the stabilizing columns 52, the position of the conveyor belt 48 can be adjusted by removing the stabilizing columns 52 from the inside of the mounting support plates 50 to make the conveyor belt 48 lose its limit.

[0042] Working principle:

[0043] When compressing and processing neodymium iron boron production waste, place the neodymium iron boron production waste on the top of the conveyor belt 48. The baffle plates 51 arranged on the top of the conveyor belt 48 block the neodymium iron boron production waste to prevent it from sliding off the top of the conveyor belt 48. The conveyor belt 48 transports the neodymium iron boron production waste to the feeding port 41 opened at the top of the processing table 38, so that the neodymium iron boron production waste enters the inside of the shaping cavity 43 through the feeding port 41. And the larger neodymium iron boron production waste can be broken by the crushing column 42 arranged inside the feeding port 41, which is convenient for subsequent extrusion. After the neodymium iron boron production waste enters the inside of the shaping cavity 43, start the hydraulic press 39, and use the hydraulic press 39 to extrude the neodymium iron boron production waste inside the shaping cavity 43, so that the neodymium iron boron production waste is compressed into blocks. After the neodymium iron boron production waste is shaped into waste blocks, start the telescopic cylinder 46, and use the telescopic cylinder 46 to push the discharge plate 47 towards the direction of the waste blocks. The discharge plate 47 pushes the waste blocks towards the discharge port 45, and then the waste blocks fall onto the top of the placing table 53;

[0044] Since the conveyor belt 48 is connected to the processing table 38 and the fixing strip 49 through the mounting support plates 50 and the stabilizing columns 52, the position of the conveyor belt 48 can be adjusted by removing the stabilizing columns 52 from the inside of the mounting support plates 50 to make the conveyor belt 48 lose its limit. And the outside of the discharge plate 47 is fitted with the inside of the mounting groove 44, which can effectively prevent the debris of the neodymium iron boron production waste from entering the inside of the mounting groove 44;

[0045] When the waste block falls to the top of the placement table 53, the motor 22 is started, and the motor 22 drives the connecting column 23 and the turntable 24 to rotate. During the rotation of the turntable 24, the limiting column 4 is driven to move synchronously. Since the outer side of the limiting column 4 is in contact with the inner side of the movable frame 5, the limiting column 4 itself will slide inside the movable frame 5 and drive the movable frame 5 to move during the process of the limiting column 4 following the rotation of the turntable 24. However, because the support columns 10 arranged on both sides of the limiting frame respectively pass through the through holes 11 opened on one side of the support block 27, Under the restriction of the through hole 11, the support column 10 can only translate along the through hole 11, thereby restricting the movement trajectory of the movable frame 5, preventing the movable frame 5 from rotating along the movement trajectory of the limiting column 4. During the movement of the movable frame 5, the push plate 12 will be driven to move toward the waste block, and the waste block will be pushed to move toward the side of the placement table 53 by the push plate 12. The support column 10 can be limited by the limiting block 13 set at one end of the support column 10 to prevent the support column 10 from being separated from the through hole 11 opened on one side of the fixed block.

[0046] When the push plate 12 moves toward the waste block, the push plate 12 will drive the top connecting plate 15 and the mounting rod 16 fixed to one end of the bottom of the connecting plate 15 to move synchronously. During the movement of the mounting rod 16, the movable plate 32 arranged inside the storage groove 19 will be driven to move. Since one side of the movable plate 32 is inclined and fits against one side of the baffle 17, and one side of the movable plate 32 located inside the storage groove 19 is connected to the inner side of the storage groove 19 through the spring 33, when the mounting rod 16 moves toward the waste block, Under the elastic action of the spring 33, the movable plate 32 is pushed to move toward the baffle 17, so that the inclined surface of the movable plate 32 is always in contact with one side of the baffle 17. At the same time, the movement of the movable plate 32 drives the limiting plate 18 to move toward the center of the pushing plate 12. When one side of the pushing plate 12 contacts one end of the waste block, the side of the limiting plate 18 away from the stabilizing rod 34 is in contact with the outer side of the waste block. The waste block is limited under the clamping of the two limiting plates 18, so that the waste block can move toward the side of the placing table 53 more stably.

[0047] It should be noted that after one side of the limit plate 18 comes into contact with the outer side of the waste block, since the pushing plate 12 is still moving, at this time, the movable plate 32 will continue to drive the limit plate 18 to move towards the center of the pushing plate 12. However, since one side of the movable plate 32 is connected to the inside of the receiving groove 19 through a spring 33, one end of the movable plate 32 has an adaptively adjustable distance. When the limit plate 18 comes into contact with the outer side of the waste block, under the elastic action of the spring 33, the extrusion force of the limit plate 18 on the waste block will be increased, and the situation where the limit block 13 is stuck and the pushing plate 12 cannot continue to move will not occur. After the pushing plate 12 pushes the waste block to the specified position, the motor 22 will reverse to make the pushing plate 12 move away from the waste block. At this time, through a plurality of rollers 37 arranged on one side of the limit plate 18, the friction between the limit plate 18 and the waste block can be reduced during the movement of the limit plate 18, thereby preventing the waste block from being driven to move by the limit plate 18 during the movement of the limit plate 18. The movement of the waste block is mainly due to the thrust applied to it by the pushing plate 12, and thus the situation where the waste block follows the limit plate 18 to continue moving will not occur. Moreover, since one side of the movable plate 32 is inclined and fits with one side of the baffle 17, when the movable plate 32 moves away from the waste block following the pushing plate 12, the inclined surface of the movable plate 32 will slide along one side of the baffle 17, and the movable plate 32 will be pushed into the receiving groove 19 by the baffle 17 and the spring 33 will be compressed;

[0048] By removing the fixed column 36 from the inside of the stabilizing block 35, the stabilizing rod 34 is released from the limit, and the stabilizing rod 34 is pulled to move it inside the through groove 20, and the position of the limit plate 18 is adjusted by the movement of the stabilizing rod 34;

[0049] The threaded column 30 is removed from the top of the fixing plate 28, so that the connecting rod 29 is released from the limit of the threaded column 30, and then the position of the connecting rod 29 inside the groove 31 can be adjusted. By adjusting the position of the connecting rod 29, the limit post 4 moves inside the chute 8 opened on the top of the turntable 24, and then the position of the limit post 4 is adjusted. After the adjustment, the threaded column 30 is inserted back into the fixing plate 28 and the connecting rod 29. By adjusting the position of the limit post 4, the movement range of the movable frame 5 can be reduced or enlarged, so as to adjust the moving distance of the pushing plate 12.
