Description

Technical Field

[0001] This invention relates to the field of copper powder impurity removal technology, specifically to a device for high-purity copper powder based on the recycling of waste lithium batteries. Background Technology

[0002] In today's digital age, the widespread use of various electronic devices such as smartphones and laptops has led to an explosive growth in the amount of waste lithium batteries. Waste lithium batteries contain many recyclable metal materials, such as copper, cobalt, and lithium. Their proper recycling and utilization can not only greatly alleviate the resource shortage, but also effectively reduce environmental pollution.

[0003] High-purity copper powder, in particular, plays an irreplaceable role in high-end fields such as electronic circuit manufacturing and precision machining, as a basic material for many key industries.

[0004] However, in the existing process of recycling high-purity copper powder from waste lithium batteries, magnetic separation is usually used to separate magnetic impurities from copper powder. After a period of time, the adsorption components in the magnetic separation equipment will accumulate a large amount of magnetic powder on their surface, which will cause the adsorption performance to drop sharply. As a result, the magnetic impurities in the copper powder are difficult to be fully adsorbed and separated, which will seriously affect the purity of the recovered copper powder. Summary of the Invention

Piston rods are symmetrically disposed on the fixed plate, and the piston rods are slidably connected to the fixed plate.

[0013] As a preferred embodiment of the device for recycling high-purity copper powder based on waste lithium batteries according to the present invention, wherein: piston cylinders are symmetrically arranged on the side of the fixed plate away from the rotating cylinder, a manifold is connected to the end of the piston cylinder away from the fixed plate, a stator tube is arranged at the end of the manifold away from the piston cylinder, the stator tube is engaged and rotatably connected to the rotating cylinder, and the end of the manifold near the stator tube is interconnected with the venting groove.

[0014] As a preferred embodiment of the device for recycling high-purity copper powder based on waste lithium batteries according to the present invention, wherein: the reciprocating rod is provided with a reciprocating cavity one and a reciprocating cavity two, the reciprocating cavity one and the reciprocating cavity two are interconnected, a moving block one is slidably arranged in the reciprocating cavity one, and a moving block two is slidably arranged in the reciprocating cavity two.

[0015] As a preferred embodiment of the device for recycling high-purity copper powder based on waste lithium batteries according to the present invention, wherein: a movable rod is slidably provided at the end of the reciprocating rod away from the collecting plate, and the two ends of the movable rod can extend into the reciprocating cavity one and the reciprocating cavity two respectively, and a magnet block one is symmetrically embedded on the reciprocating rod.

[0016] As a preferred embodiment of the device for recycling high-purity copper powder from waste lithium batteries according to the present invention, wherein: a second magnet is symmetrically embedded in the reciprocating rod, a pressure relief groove is symmetrically opened at one end of the reciprocating rod near the moving rod, and a pressure relief block is slidably arranged in the pressure relief groove.

[0017] As a preferred embodiment of the device for recycling high-purity copper powder based on waste lithium batteries according to the present invention, wherein: a collection cavity is provided in the collection plate, the adsorption rod extends into the collection cavity, and the adsorption rod located inside the collection cavity is made of aluminum, and a sleeve is sleeved on the outside of the adsorption rod, and the sleeve is engaged and slidably disposed in the collection cavity.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By tilting the separation cylinder and arraying separation grooves and vertically setting separation plates inside it, the separation grooves are divided into multiple throwing grooves. During the tilting and rotating process of the separation cylinder, magnetic impurities and copper powder are continuously tumbled in the throwing grooves by centrifugal force and gravity, which prevents magnetic impurities and copper powder from sticking together. Then, the magnetic attraction of the adsorption rod is used to adsorb the magnetic impurities on its surface, thereby separating the magnetic impurities from the copper powder. This improves the separation effect of magnetic impurities in copper powder and thus improves the purity of the separated copper powder.

[0020] 2. By setting up pneumatic components, reciprocating components, and cleaning components, the pneumatic components drive the reciprocating components during the rotation of the separation cylinder, causing the connecting block to move the moving disk. The cleaning shovels on the movable blades scrape off the magnetic impurities attached to the surface of the adsorption rod, avoiding the problem of decreased adsorption performance of the adsorption rod due to the accumulation of magnetic impurities on the surface of the adsorption rod. This ensures that the accumulated magnetic powder on the surface of the adsorption rod can be removed in time, guaranteeing the continuous and efficient adsorption performance of the adsorption rod, thereby improving the purity of the separated copper powder.

[0021] 3. By setting a collection chamber inside the collection plate, and setting the part of the adsorption rod located in the collection chamber to be non-magnetic, the magnetic impurities pushed by the cleaning shovel into the collection chamber are not affected by the magnetic attraction of the adsorption rod. Instead, they are displaced to the side wall area of ​​the collection chamber by the centrifugal force of the rotating separation cylinder. This isolates the magnetic impurities separated from the separation cylinder from the inside of the separation cylinder, thereby reducing the content of magnetic impurities in the separation cylinder, improving the separation effect of magnetic impurities in copper powder, and thus improving the purity of copper powder.

Well-known structures and techniques are not shown in the drawings and the following description in order to avoid unnecessarily obscuring the invention.

[0040] Example 1

[0041] Reference Figure 1-5This first embodiment of the invention provides an apparatus for processing high-purity copper powder from recycled waste lithium batteries. The apparatus includes a base 1, a drive assembly on the base 1, a separation cylinder 11 inclinedly mounted on the drive assembly, and a gear ring 1 and a gear ring 2 respectively mounted at both ends of the separation cylinder 11. The drive assembly includes two fixed frames mounted on the base 1. The separation cylinder 11 is rotatably mounted on the fixed frames. Shaft seats are symmetrically arranged at the lower region of the separation cylinder 11, and the shaft seats are fixedly mounted on the upper surface of the base 1. A rotating shaft is rotatably mounted on the shaft seats, positioned between the two shaft seats, and gear 1 and gear 2 are respectively mounted at both ends of the rotating shaft. Gear 1 and Gear 2 are both coaxially connected to the rotating shaft, which can drive Gear 1 and Gear 2 to rotate synchronously. A motor base 1 is also provided on the upper surface of the machine base 1. A motor is provided on the motor base 1. The motor output shaft passes through the motor base 1 and is coaxially connected to the rotating shaft. Gear 1 meshes with Gear Ring 1, and Gear 2 meshes with Gear Ring 2. A sliding groove is provided on the side of Gear Ring 2 away from Gear Ring 1. A receiving box is provided on the upper surface of the machine base 1. The receiving box is engaged and slidably connected to the machine base 1. A slider is provided at one end of the receiving box near the separating cylinder 11. The slider is slidably disposed in the sliding groove. Separating grooves 12 are arrayed inside the separating cylinder 11. Separating plates 13 are arrayed inside the separating cylinder 11. The separating plates 13 and the separating grooves 12 are arranged perpendicular to each other.

[0042] The separation cylinder 11 is provided with a collection plate 14 and a pneumatic plate 15 at both ends. The collection plate 14 is provided with a feed pipe 141, one end of which passes through the collection plate 14. The material can enter the interior of the separation cylinder 11 through the feed pipe 141. The pneumatic plate 15 is provided with a pneumatic component 2 on the side away from the collection plate 14. At least three magnetic separation components are arranged in an array inside the separation cylinder 11. The magnetic separation components are connected to the collection plate 14 and the pneumatic plate 15 at both ends. The magnetic separation components include an adsorption rod 16, a cleaning component 3, and a reciprocating component 4. The reciprocating component 4 includes a reciprocating rod 41. The reciprocating component 4 can drive the cleaning component 3 to scrape off the magnetic powder on the surface of the adsorption rod 16.

[0043] The cleaning component 3 includes a movable disk 31, a connecting block 32 on one side of the movable disk 31, the connecting block 32 being made of magnetic material, the connecting block 32 being slidably connected to the reciprocating rod 41, a plurality of movable blades 33 being hinged inside the movable disk 31, a movable ring 34 being rotatably mounted inside the movable disk 31, a toothed structure being mounted on the outer side of the movable ring 34, a plurality of connecting rods 35 being hinged on the movable ring 34, the end of the connecting rod 35 away from the movable ring 34 being hinged to the movable blades 33, a cleaning shovel 36 being mounted on the movable blades 33, and an opening and closing assembly 37 being mounted on the side of the movable disk 31 away from the connecting block 32.

[0044] The separation plate 13 divides the separation tank 12 into multiple throwing tanks 17, and the end of the separation plate 13 away from the end connected to the separation cylinder 11 is provided with a bend. The adsorption rod 16 is made of a strong magnetic material, and the magnetic impurities in the material will be adsorbed onto the surface of the adsorption rod 16 by magnetic force.

[0045] During use, the motor is first started so that the motor output shaft rotates and synchronously drives the rotating shaft. Then, gear one and gear two will follow the rotating shaft and rotate synchronously, driving gear ring one and gear ring two. At this time, the separator cylinder 11 starts to rotate.

[0046] Copper powder containing magnetic impurities, i.e., mixed powder, is fed into the separator 11 through the feed pipe 141. At this time, the mixed powder will fall into multiple throwing troughs 17. As the separator 11 continues to rotate, the mixed powder in the multiple throwing troughs 17 will be continuously lifted by the separator 11.

[0047] When the mixed powder in the throwing trough 17 is lifted to a position close to the limit height area in the separation cylinder 11, the bending structure on the separation plate 13 will block the mixed powder. When the mixed powder has moved to the limit height area in the separation cylinder 11, the bending structure on the separation plate 13 will no longer be able to block the mixed powder in the throwing trough 17. At this time, the mixed powder in the throwing trough 17 will be thrown out at the limit height area in the separation cylinder 11.

[0048] The mixed powder thrown out from the throwing trough 17 will fall towards the adsorption rod 16 under the action of gravity. When the magnetic impurities in the mixed powder approach the adsorption rod 16, the magnetic impurities will be adsorbed on the surface of the adsorption rod 16 under the action of magnetic force, while the copper powder will fall into the throwing trough 17 at the bottom of the separating cylinder 11 without being affected by magnetic force. The mixed powder that falls back into the throwing trough 17 will pass through the adsorption rod 16 again as the separating cylinder 11 moves, so that the magnetic impurities in the mixed powder are removed. Since the separating cylinder 11 is tilted, the mixed powder will gradually move towards the pneumatic plate 15 after being thrown out from the throwing trough 17 each time, until the copper powder is discharged from the end of the separating cylinder 11 near the pneumatic plate 15 and falls into the receiving box.

[0049] Example 2

[0050] Reference Figure 1-11 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0051] The opening and closing assembly 37 includes a housing 371, a drive gear 372 rotatably disposed within the housing 371, a twisted rod 373 slidably disposed in the middle of the drive gear 372, the drive gear 372 meshing with the tooth structure on the outer side of the moving ring 34, limit rods provided at both ends of the twisted rod 373, the limit rods penetrating the housing 371, iron plates provided at both ends of the limit rods, and magnetic plates embedded on both sides of the housing 371. The pneumatic assembly 2 includes a bracket 21 and a baffle 22 disposed on the bracket 21, the baffle 22 being rotatably connected to the separating cylinder 11, a pneumatic plate 15 being rotatably disposed within the baffle 22, and a pneumatic cavity being provided within the pneumatic plate 15, one end of the bracket 21 being connected to the base 1, the baffle 22 being disposed at the end of the bracket 21 away from the base 1, a through hole being opened in the middle region of the baffle 22, and the pneumatic plate 15 being disposed within the through hole.

[0052] A rotating cylinder 23 is provided at the end of the pneumatic plate 15 away from the separating cylinder 11. A guide strip 231 is provided on the outside of the rotating cylinder 23. A ventilation groove 232 is provided inside the rotating cylinder 23. The ventilation groove 232 communicates with the pneumatic cavity.

[0053] The pneumatic assembly 2 also includes a second bracket 24 and a fixed plate 25 disposed on the second bracket 24. Piston rods 26 are symmetrically disposed on the fixed plate 25 and are slidably connected to the fixed plate 25. One end of the second bracket 24 is connected to the base 1. The fixed plate 25 is disposed at the end of the second bracket 24 away from the base 1. Two pulleys are rotatably disposed at one end of the piston rod 26. An appropriate gap is left between the two pulleys. A guide bar 231 is disposed between the two pulleys, and the pulleys can slide along the guide bar 231.

[0054] A piston cylinder 27 is symmetrically arranged on the side of the fixed plate 25 away from the rotating cylinder 23. A manifold 28 is connected to the end of the piston cylinder 27 away from the fixed plate 25. A stator tube 29 is arranged at the end of the manifold 28 away from the piston cylinder 27. The stator tube 29 is engaged and rotatably connected to the rotating cylinder 23. The end of the manifold 28 near the stator tube 29 is connected to the vent groove 232.

[0055] The end of the piston rod 26 away from the pulley is located inside the piston cylinder 27. A one-way valve is provided in the piston cylinder 27 away from the fixed plate 25. Gas outside the piston cylinder 27 can enter the piston cylinder 27 through the one-way valve. A one-way valve is provided at the connection between the piston cylinder 27 and the manifold 28. Gas inside the piston cylinder 27 can enter the manifold 28 through the one-way valve.

[0056] A stator plate is fixedly installed between the two piston cylinders 27. The stator plate is fixedly connected to the stator tube 29. The stator plate can support and fix the stator tube 29. The gas in the manifold 28 can enter the ventilation slot 232 through the stator tube 29.

[0057] The reciprocating rod 41 has a reciprocating cavity 1 42 and a reciprocating cavity 2 43, which are interconnected. A moving block 1 421 is slidably arranged in the reciprocating cavity 1 42, and a moving block 2 431 is slidably arranged in the reciprocating cavity 2 43. One end of both the moving block 1 421 and the moving block 2 431 is provided with a chamfered structure. The moving block 1 421 is preferably made of a magnet. The moving block 1 421 and the connecting block 32 are attracted to each other under the action of magnetic force. The displacement of the moving block 1 421 can pull the connecting block 32 to move synchronously. Air pipes are arranged in an array on the pneumatic plate 15. The end of the air pipe away from the pneumatic plate 15 is connected to the end of the reciprocating rod 41 away from the collecting plate 14. The pneumatic cavity and the reciprocating cavity 1 42 are connected through the air pipes.

[0058] A movable rod 44 is slidably provided at the end of the reciprocating rod 41 away from the collecting plate 14. The two ends of the movable rod 44 can extend into the reciprocating cavity 1 42 and the reciprocating cavity 2 43 respectively. Magnet blocks 1 45 are symmetrically embedded on the reciprocating rod 41. The movable rod 44 can block the reciprocating cavity 1 42 and the reciprocating cavity 2 43. Both ends of the movable rod 44 are provided with chamfered structures.

[0059] A second magnet 46 is symmetrically embedded in the reciprocating rod 41. A pressure relief groove is symmetrically opened at one end of the reciprocating rod 41 near the moving rod 44. A pressure relief block 47 is slidably arranged in the pressure relief groove. When the moving rod 44 moves, the first magnet 45 can overlap, contact and attract with the second magnet 46. Side plates are symmetrically arranged at both ends of the pressure relief block 47. Spring pieces are arranged on the side plates. An exhaust groove is arranged in the pressure relief block 47. An air outlet groove is arranged at the ends of the two pressure relief blocks 47 that are far apart from each other. The exhaust groove and the air outlet groove are interconnected. Dustproof nets are arranged at the openings at both ends of the air outlet groove to prevent materials from entering the air outlet groove.

[0060] During use, when the motor drives the separator cylinder 11 to rotate, the pneumatic plate 15 will drive the rotating cylinder 23 to rotate synchronously. At this time, the guide bar 231 on the rotating cylinder 23 will rotate synchronously with the rotating cylinder 23. Then, the two piston rods 26 will reciprocate and extend under the guidance of the guide bar 231, causing the gas outside the piston cylinder 27 to enter the piston cylinder 27 through the one-way valve one, and then be compressed by the piston rod 26, and finally enter the manifold 28 through the one-way valve two.

[0061] The gas in the manifold 28 enters the venting slot 232 through the stator tube 29, and then enters the pneumatic slot through the venting slot 232. Under the action of pressure, the gas in the pneumatic slot is introduced into the chamber inside the reciprocating rod 41 through the air pipe.

[0062] When the gas in the pneumatic chamber enters the reciprocating chamber 42, the moving block 421 will move toward the collecting plate 14, and the moving block 431 will move away from the collecting plate 14. During this process, one end of the moving rod 44 extends into the reciprocating chamber 43, and the moving rod 44 pushes against the pressure relief block 47 near one end of the reciprocating chamber 43. At this time, the gas inside the reciprocating chamber 43 can be discharged through the exhaust groove and the air outlet groove on the pressure relief block 47.

[0063] At the same time, the cleaning component 3 moves synchronously with the moving block 421. At this time, multiple moving blades 33 converge with each other, and the cleaning shovel 36 adheres to the surface of the adsorption rod 16 and scrapes off the magnetic powder adsorbed on the surface of the adsorption rod 16 during the movement.

[0064] When the first moving block 421 moves the cleaning component 3 to its limit position, the collecting plate 14 pushes the twisted rod 373, which then drives the drive gear 372 to rotate. The drive gear 372 then drives the moving ring 34 to rotate, and multiple connecting rods 35 pull the movable blades 33 to move away from each other. At this time, the second moving block 431 will push the moving rod 44 under the action of gas pressure, causing the moving rod 44 to shift and extend into the reciprocating cavity 42. At this time, the pressure relief block 47 near the reciprocating cavity 42 will be pushed by the moving rod 44. When the push is moved, the moving rod 44 will block the reciprocating chamber 1 42, and the gas in the pneumatic chamber will be introduced into the reciprocating chamber 2 43. Then, the moving block 1 421 will move synchronously with the moving block 2 431 under the action of gas pressure. Then, the cleaning component 3 will move synchronously with the moving block 1 421 and gradually reset. When the moving block 1 421 drives the cleaning component 3 to reset to the appropriate position, the pneumatic plate 15 will push the twist rod 373, so that the moving ring 34 will rotate and the multiple movable blades 33 will close each other. The cleaning shovel 36 will once again adhere to the surface of the adsorption rod 16.

[0065] The remaining structure is the same as that in Example 1.

[0066] Example 3

[0067] Reference Figure 1-12 This is the third embodiment of the present invention, which differs from the second embodiment in that:

[0068] The collection plate 14 is provided with a collection cavity 142, the adsorption rod 16 extends into the collection cavity 142, and the adsorption rod 16 located inside the collection cavity 142 is made of aluminum. A sleeve 161 is sleeved on the outside of the adsorption rod 16, and the sleeve 161 is engaged and slidably disposed in the collection cavity 142. A spring is provided inside the sleeve 161.

[0069] During use, when the cleaning shovel 36 pushes the magnetic impurities on the adsorption rod 16 toward the collection plate 14 to the limit position, the cleaning shovel 36 will push the sleeve 161 and move into the collection chamber 142. The spring will deform, and the magnetic impurities pushed into the collection chamber 142 by the cleaning shovel 36 will not be affected by the magnetic force of the adsorption rod 16 at this time.

[0070] Since the collecting plate 14 rotates synchronously with the separating cylinder 11, the magnetic impurities are dislodged from the cleaning shovel 36 and collected in the collecting chamber 142 under the action of centrifugal force. When the cleaning component 3 is reset, the sleeve 161 is reset under the action of the spring force.

[0071] The remaining structure is the same as that in Example 2.
