Description

Technical Field

[0001] This invention relates to the field of recycling usable portions of waste batteries, specifically a wind-powered composite sorting device for collecting battery black powder. Background Technology

[0002] Black powder is a black powder rich in valuable metals such as lithium, nickel, and cobalt, obtained from the recycling and processing of retired lithium batteries. It plays a core role in the new energy industry. As a key intermediate product for recycling, it is a direct raw material for refining high-purity battery materials (such as lithium carbonate and ternary precursors) and used in the manufacture of new batteries, thus realizing a closed-loop cycle of resources.

[0003] The common method for recovering black powder is wind separation. During the separation process, the crushed material is stirred, and the black powder attached to the crushed material is knocked off. The black powder is then discharged by wind, while the crushed material is intercepted. After the black powder is separated, the crushed material needs to be discharged. In the existing technology, it must be discharged along with other crushed materials before the next black powder separation can be carried out. The discharge process takes a long time, and if there is a blockage in the discharge, it needs to be cleared before the discharge can continue, which affects the efficiency of the next black powder separation.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 11In this embodiment of the invention, a wind-powered composite sorting device for collecting battery black powder includes a sorting tank 1 with a black powder discharge pipe 2 at the bottom. A discharge box 3 is fixedly installed on the lower outer wall of the sorting tank 1, and the discharge box 3 is connected to the inner cavity of the sorting tank 1. A fixing rod 14 is welded between the inner circumference of the outer ring of the discharge box 3 and the outer circumference of the inner ring of the discharge box 3. The bottom plate of the discharge box 3 is inclined, and a downwardly protruding impurity discharge pipe 4 is installed at the lowest position of the bottom of the discharge box 3. A power mechanism extending into the inner cavity of the sorting tank 1 is installed above the sorting tank 1. A shielding ring 13 is slidably installed in the inner cavity of the sorting tank 1. The shielding ring 13 at the highest position is used to shield the inner circumferential opening of the discharge box 3. An intercepting net 12 is fixedly installed on the top of the inner circumference of the shielding ring 13. A clamping mechanism is installed between the inner circumference of the shielding ring 13 and the lower inner wall of the sorting tank 1. A clamping mechanism is provided between the inner wall of the sorting tank 1 and the outer circumference of the shielding ring 13. The guiding mechanism includes a stirrer 11 installed on the outer wall of the rotating shaft 5 above the intercepting net 12. A feed pipe 9 is fixedly installed on the top of the sorting tank 1, and the straight part of the feed pipe 9 is connected to the air pipe 10. The power mechanism includes a rotating shaft 5 that extends from the top of the sorting tank 1 into the inner cavity of the sorting tank 1. The rotating shaft 5 is rotatably connected to the sorting tank 1. A pulley 6 is mounted on the outer wall of the rotating shaft 5 above the sorting tank 1. A pressure rod 7 is movably connected to the inner wall of the rotating shaft 5. A fixing plate 8 is rotatably installed on the top of the outer wall of the pressure rod 7. The power mechanism also includes a pressure plate 23 fixedly installed at the bottom of the pressure rod 7. The top of the pressure plate 23 has a tapered structure that is wider at the top and narrower at the bottom. An annular groove 24 is opened at the bottom of the pressure plate 23. A sliding groove 17 for the pressure plate 23 to slide up and down is opened inside the rotating shaft 5 below the intercepting net 12. A through hole 34 that is slidably connected to the rotating shaft 5 is opened at the center of the pressure plate 23.

[0031] In this embodiment: First, the crushed battery raw materials are fed into the sorting tank 1 by a feeding device (e.g., a screw conveyor rod installed on the inner wall of the straight section of the feed pipe 9), and are intercepted at the top of the interception net 12. Then, the belt drive mechanism is started, driving the pulley 6 to rotate. At this time, the pulley 6 can drive the agitator 11 to rotate through the rotating shaft 5. The rotating agitator 11 can disperse the added crushed material, knocking off the black powder attached to the surface of the crushed material. At the same time, the blower is started, and the blower inputs external air into the air pipe 10 through the pipe. The flowing air carries the knocked-off black powder through the interception net 12 into the lower part of the sorting tank 1, and is discharged downward through the black powder discharge pipe 2. After completion, for example, a dust monitoring sensor is installed on the black powder discharge pipe 2. After the black powder is gradually discharged, the dust monitoring sensor sends an electrical signal to the controller. The controller controls the discharge completion signal light to light up. At this time, the operator can start the electric push cylinder connected to the fixed plate 8. The electric push cylinder moves the pressure rod 7 downward through the fixed plate 8. The pressure rod 7 then pushes the pressure plate 23 downward. The pressure plate 23 then pushes the upper part of the clamping mechanism downward to dock with the lower part of the clamping mechanism, thus clamping the clamping mechanism under the outer wall of the rotating shaft 5. At this time, the rotating shaft 5 can drive the upper part of the clamping mechanism to rotate, thereby driving the shielding ring 13 and the interception net 12 to rotate.

[0032] Meanwhile, after the shielding ring 13 moves down to the lowest position, it no longer blocks the inner opening of the discharge box 3. At the same time, it enters the lowest point of the guide mechanism, and the intercepting net 12 unfolds into a "quasi-triangular structure". The rotating intercepting net 12 can quickly throw the intercepted crushed material into the interior of the discharge box 3, and discharge it outward from the impurity discharge pipe 4 through the inclined bottom plate of the discharge box 3. Then, the electric push cylinder can be activated to reset, so that the intercepting net 12 and the shielding ring 13 are reset, and the inner opening of the discharge box 3 is blocked again to prevent black powder from being discharged outward during the next black powder sorting.

[0033] This design allows for the rapid discharge of crushed material, excluding black powder, facilitating the next black powder sorting process. It also avoids blockages caused by the discharge of crushed material, which could affect the efficiency of the next black powder sorting process. If a blockage occurs, the impurity discharge pipe 4 can be cleared separately without affecting the normal operation of the sorting tank 1.

[0034] Please refer to this carefully. Figure 10 and Figure 11The interception net 12 consists of multiple interlocking and ring-shaped interception rings 30. The central interception ring 30 is sleeved with the outer wall of the rotating shaft 5. Adjacent interception rings 30 are slidably connected by a sliding mechanism. The sliding mechanism includes a connecting block 33 fixedly installed on the lower outer periphery of the interception ring 30 and a connecting groove 32 opened on the inner periphery of the adjacent interception ring 30. The connecting block 33 is slidably installed in the inner cavity of the connecting groove 32.

[0035] In this embodiment: when the shielding ring 13 moves downward, the shielding ring 13 drives the outermost intercepting ring 30 to move downward synchronously. The downward-moving intercepting ring 30 drives the inner connecting groove 32 to move downward synchronously. At this time, the other adjacent intercepting ring 30 can unfold under the action of gravity, so that the entire intercepting net 12 unfolds into a triangular structure. When the shielding ring 13 no longer blocks the internal opening of the discharge box 3, the crushed material can be quickly discharged into the discharge box 3 under the rotational centrifugal force and guidance, which greatly improves the discharge speed of other crushed materials and avoids the problem of blockage affecting the efficiency of the next sorting.

[0036] Please refer to this carefully. Figure 5 and Figure 6 The guiding mechanism also includes two vertical grooves 25 vertically opened on the inner wall of the sorting tank 1. The inner wall of the sorting tank 1 has a guide groove 26 distributed in a ring at the bottom end of the vertical groove 25. The inner cavity of the vertical groove 25 is connected to the inner cavity of the guide groove 26. The bottom end of the inner wall of the guide groove 26 has a planar structure. The top end of the bottom wall of the guide groove 26 has two inclined surfaces 27. The two inclined surfaces 27 are distributed in an "X" shape from the front view angle. The inner cavity of the discharge box 3 is connected to the inner cavity of the guide groove 26. The guiding mechanism includes two No. 2 balls 31 movably connected to the outermost intercepting ring 30. The two No. 2 balls 31 are symmetrically distributed.

[0037] In this embodiment: as the shielding ring 13 moves downward, it drives the second ball 31 to move downward along the inner wall of the vertical groove 25 until the second ball 31 contacts the bottom of the inner wall of the guide groove 26. At this time, the shielding ring 13 no longer blocks the internal opening of the discharge box 3. Then the shielding ring 13 rotating with the rotating shaft 5 and the unfolded intercepting net 12 can discharge the crushed material into the discharge box 3.

[0038] After the material is discharged, when the shielding ring 13 moves upward to reset, the second ball 31 will come into contact with the inclined surface 27. Under the guidance of the inclined surface 27, the shielding ring 13 will rotate until the second ball 31 is inserted into the vertical groove 25. In this way, no matter what position or angle the shielding ring 13 rotates to, it can be guaranteed that it will be smoothly inserted into the vertical groove 25 during the upward movement.

[0039] Please refer to this carefully. Figure 2 , Figure 3 and Figure 9The clamping mechanism includes two connecting sleeves 18 fixedly installed on the inner circumference of the shielding ring 13. A sliding rod 19 extending to the outside of the connecting sleeve 18 is axially slidably installed in the inner cavity of the connecting sleeve 18. A connector 20 is fixedly installed at the bottom end of the sliding rod 19. A ball bearing 21 is movably installed at the outer end of the connector 20. A clamping sleeve 22 for clamping the lower part of the outer wall of the rotating shaft 5 is fixedly installed at the inner end of the connector 20. A fixing block 28 is fixedly installed at the top of the connecting sleeve 18, and the pressure plate 23 is movably connected... The clamping mechanism also includes a connecting rod 15 fixedly installed on the inner wall of the sorting tank 1 and located below the shielding ring 13. A fixing ring 16 is fixedly installed on the inner circumference of the connecting rod 15. The upper half of the inner wall of the fixing ring 16 is a compression cone surface that is wider at the top and narrower at the bottom. The inner wall of the fixing ring 16 is a vertical hollow circular hole structure. The inner diameter of the hollow circular hole is equal to the inner diameter of the bottom end of the compression cone surface. A spring 29 is connected between one end of the inner cavity of the connecting sleeve 18 and one end of the straight rod end of the sliding rod 19.

[0040] In this embodiment: During the downward movement of the pressure plate 23, the pressure plate 23 pushes the connecting sleeve 18 downward, and the connecting sleeve 18 drives the sliding rod 19 downward until the first ball 21 contacts the inner conical surface of the fixed ring 16. During this process, the first ball 21 is subjected to a squeezing force, and the first ball 21 drives the sliding rod 19 to slide. At this time, the spring 29 is compressed, and the two clamping sleeves 22 will move closer to each other until the first ball 21 enters the hollow round hole. At this time, the two clamping sleeves 22 are tightly clamped on the outer wall of the rotating shaft 5. The rotating shaft 5 can then drive the clamping sleeves 22 clamped on its outer periphery to rotate. The clamping sleeves 22 can then drive the shielding ring 13 to rotate through the sliding rod 19 and the connecting sleeve 18. The centrifugal force generated during rotation can quickly throw out the crushed material.

[0041] After the upper part of the clamping mechanism is reset, the rotating shaft 5 drives the intercepting net 12 to rotate, so that when the agitator 11 rotates, the intercepting net 12 is stationary. This avoids the problem of insufficient stirring and separation force caused by synchronous rotation. If the intercepting net 12 rotates synchronously, it will drive the crushed material on its top to rotate, causing the relative speed with the agitator 11 to decrease.

[0042] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
