Description

Technical Field

[0001] This invention belongs to the field of waste battery recycling technology and relates to a sorting device for waste battery recycling. Background Technology

[0002] Heavy metals such as nickel, cobalt, manganese, and lithium contained in waste batteries can cause long-term pollution to water bodies and soil if not properly disposed of. Therefore, waste battery recycling is an important environmental protection initiative that helps reduce environmental pollution from waste batteries, promotes resource recycling, and contributes to a green, low-carbon, and circular economy. Current technology typically involves setting up recycling bins for centralized collection and processing. However, during centralized collection, if batteries are not fully discharged before being placed in the recycling bins, moisture and compression can cause leakage or spontaneous combustion, posing a safety hazard.

[0003] A lithium battery recycling bin is disclosed in patent document CN113148483A. In this invention, waste batteries are inserted into a storage component via a feeding component. A top-positioning element pushes the lithium batteries into a serpentine trough, and a limiting element located within the serpentine trough fixes the lithium batteries in place. The bin can only move to the next compartment when another lithium battery is inserted, preventing the batteries from being removed from the feeding component and effectively preventing theft. However, this recycling bin does not solve the problems of battery leakage or spontaneous combustion.

[0004] To address the above problems, this invention proposes a sorting device for waste battery recycling. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a sorting device for waste battery recycling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sorting device for waste battery recycling, comprising a discharge box with an inlet, a first turntable, and a discharge mechanism; the first turntable is rotatably disposed inside the discharge box, and a first slot is formed on the first turntable, and a second slot for accommodating the battery body is formed on the side wall of the first slot; a discharge mechanism is provided on the first turntable at a position corresponding to each second slot, and each discharge mechanism includes a clamping block, an electromagnet, and a discharger; there are two clamping blocks, which are slidably disposed at both ends of the second slot, and the electromagnet and the discharger are both disposed inside the first turntable. When the two clamping blocks clamp the battery body in the second slot, the battery body, the clamping blocks, the electromagnet, and the discharger form a series circuit; an arc-shaped protrusion is provided on the inner wall of the discharge box to drive the clamping blocks to move closer to the second slot, and a sliding plate is elastically movably disposed inside the first turntable. The two ends of the sliding plate are respectively connected to the two clamping blocks through connecting rods. When the clamping blocks move closer to the second slot, the sliding plate moves closer to the electromagnet, and the sliding plate and the electromagnet are attracted and engaged.

[0007] Furthermore, the upper part of the discharge box is connected to a feeding mechanism, which includes a feeding funnel and a connecting box. One end of the connecting box is connected to the feeding port, and the other end of the connecting box is connected to the lower end of the feeding funnel. The interior of the connecting box is adapted to the battery body.

[0008] Furthermore, the lower end of the discharge box is open and both sides are fixedly connected to guide plates. The guide plates are inclined and a gap is formed between the lower ends of the two guide plates to allow the battery body to pass through.

[0009] A second turntable is rotatably disposed below the guide plate, and the second turntable slides in conjunction with the lower end of the guide plate; a third slot is provided on the circumferential surface of the second turntable, and the battery body falling from between the two guide plates falls into the third slot; a guide block is provided on one side of the second turntable.

[0010] Furthermore, the thickness of the second turntable is less than the length of the battery body, and both ends of the second turntable are provided with cutters to cut off the ends of the battery body.

[0011] Furthermore, a base plate is provided below the discharge box, and a fixing plate is fixed on the base plate. The second turntable and the cutter are both rotatably mounted on the fixing plate. Large gears are coaxially fixedly connected to both ends of the second turntable, and each large gear meshes with a small gear. The small gear is coaxially fixedly connected to the cutter on the same side.

[0012] Furthermore, a second limiting frame is provided at the lower end of the guide block. Both ends of the second limiting frame are provided with circular holes, and the axes of the two circular holes are on the same straight line. An electric push rod is provided at one end of the second limiting frame, and a first limiting frame is provided at the other end of the second limiting frame. After the battery body falls from the second turntable, it rolls along the guide block into the second limiting frame. Then, the electric push rod is activated, and the electric push rod pushes the positive and negative electrode materials in the battery body from the outer shell into the first limiting frame, while the outer shell remains in the second limiting frame.

[0013] Furthermore, a boss is fixed on the inner wall of the discharge box to limit the position of the battery body.

[0014] Furthermore, a second discharge port is provided on the bottom plate, and a baffle is rotatably installed at the discharge port; a third motor is embedded in the bottom plate, and the third motor is connected to the baffle for driving; a second collection box is placed below the second discharge port.

[0015] Furthermore, a first discharge port is provided on the base plate, and a first collection box is provided below the first discharge port. The positive and negative electrode materials entering the first limiting frame enter the first collection box through the first discharge port.

[0016] Furthermore, a third discharge port is provided on the bottom plate, and a third collection box is provided below the third discharge port. The end of the battery body that has been cut off by the cutter falls into the third collection box.

[0017] Compared with the prior art, the present invention has the following advantages: as the first turntable rotates, the battery body in the feeding funnel automatically enters the first slot and then enters the second slot, which has a high level of automation and high efficiency.

[0018] While the clamping block clamps and fixes the battery body, the clamping block, the battery body, the electromagnet and the discharger form a series circuit. The discharger discharges the battery body, and the electromagnet is energized, so that the clamping block keeps clamping and fixing the battery body, keeping the battery body in the second slot and continuously discharging, which also helps to improve the discharge speed of the battery body.

[0019] After the battery body has finished discharging, the electromagnet is de-energized, the clamping block releases its restraint on the battery body, and as the first turntable rotates, the battery body falls out of the first turntable.

[0020] After the battery has finished discharging, it automatically falls into the third slot. As the second turntable rotates, a cutter removes its ends. Then, an electric push rod separates the positive and negative electrode materials from the casing, thus achieving the sorting and collection of the battery. This device automatically discharges, disassembles, and sorts the battery, facilitating subsequent processing and achieving high efficiency. Attached Figure Description

Detailed Implementation

[0040] 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.

[0041] like Figures 1-17 The image shows a sorting device for recycling waste batteries.

[0042] Example 1: The technical solution adopted by the present invention is as follows: A sorting device for waste battery recycling includes a discharge box, a first turntable 17 and a discharge mechanism.

[0043] The discharge box is formed by a first housing 1 and a second housing 2, which are fixedly connected. The discharge box has an inlet 32 ​​for the battery body 16 to enter. Figure 1 As shown, the feed inlet 32 ​​is located in the upper left part of the discharge box.

[0044] The feed inlet 32 ​​is connected to a feeding mechanism. The feeding mechanism includes a feed funnel 3 and a connecting box. One end of the connecting box is connected to the feed funnel 3, and the other end of the connecting box is connected to the feed inlet 32. The interior of the connecting box is adapted to the battery body 16, so that the battery body 16 is arranged in a single row inside the connecting box. The battery body 16 in the feed funnel 3 enters the discharge box sequentially through the connecting box and the feed inlet 32.

[0045] The first turntable 17 is rotatably mounted inside the discharge chamber. Specifically, a first motor 4 is fixedly mounted on the second housing 2, and the output shaft of the first motor 4 is coaxially and fixedly connected to the first turntable 17. Multiple first slots 18 are spaced apart on the first turntable 17. The openings of the first slots 18 mate with the feed inlet 32. When the first slot 18 is connected to the feed inlet 32, the battery body 16 enters the first slot 18 through the feed inlet 32.

[0046] A second slot 19 for accommodating the battery body 16 is formed on the side wall of the first slot 18. In this embodiment, each first slot 18 has three second slots 19, which are spaced apart along the length of the first slot 18.

[0047] Both the inner walls of the first housing 1 and the second housing 2 are fixedly provided with protrusions 31, which are symmetrically arranged and limit the end of the battery body 16. When the battery body 16 enters the first slot 18, the battery body 16 is placed symmetrically in the first slot 18.

[0048] A discharge mechanism is provided at the position corresponding to each of the second slots 19 on the first turntable 17. For example... Figure 6 As shown, each discharge mechanism includes a clamping block 24, an electromagnet 28, and a discharger 29. There are two clamping blocks 24, which are slidably disposed at both ends of the second slot 19. Specifically, the clamping blocks 24 are L-shaped, and a first sliding groove is provided on the first turntable 17. The horizontal portion of the clamping block 24 is slidably disposed within the first sliding groove. The two clamping blocks 24 are used to clamp and fix the two ends of the battery body 16 within the second slot 19.

[0049] A second sliding groove is provided on the first turntable 17, and a sliding plate 26 is slidably disposed in the second sliding groove. The sliding direction of the sliding plate 26 is perpendicular to the sliding direction of the clamping block 24. Both ends of the sliding plate 26 are hinged with connecting rods 25, and the two connecting rods 25 correspond one-to-one with the two clamping blocks 24. The end of the connecting rod 25 away from the sliding plate 26 is hinged to the corresponding clamping block 24.

[0050] Both the electromagnet 28 and the discharger 29 are fixed within the second sliding groove, with the electromagnet 28 positioned close to the sliding plate 26. A spring 27 is fixedly connected between the sliding plate 26 and the electromagnet 28. The sliding plate 26 is made of iron, and the electromagnet 28 are attracted to each other.

[0051] One end of the electromagnet 28 is electrically connected to one end of the discharger 29, and the other end of the electromagnet 28 is electrically connected to one of the clamping blocks 24. The other end of the discharger 29 is electrically connected to the other clamping block 24. When the two clamping blocks 24 move closer to the battery body 16, the sliding plate 26 moves closer to the electromagnet 28. When the two clamping blocks 24 clamp the battery body 16, the battery body 16, clamping blocks 24, electromagnet 28, and discharger 29 form a series circuit. If the battery body 16 is not fully discharged at this time, the discharger 29 discharges the battery body 16. When the electromagnet 28 is energized, it attracts the sliding plate 26, thereby keeping the clamping blocks 24 clamping the battery body 16, which also helps to accelerate the discharge of the battery body 16. When the battery body 16 has finished discharging, the electromagnet 28 loses its magnetism, and the sliding plate 26 moves away from the electromagnet 28 under the action of the spring 27, causing the clamping blocks 24 to move away from the battery body 16 and release their restraint on the battery body 16.

[0052] Both the upper inner walls of the first housing 1 and the second housing 2 are provided with arc-shaped protrusions 30, which are symmetrically arranged. The arc-shaped protrusions 30 cooperate with the clamping block 24. When the clamping block 24 slides along the arc-shaped protrusions 30, under the action of the arc-shaped protrusions 30, the clamping block 24 moves closer to the battery body 16 and then contacts the battery body 16. In order to allow the clamping block 24 to smoothly enter the arc-shaped protrusions 30, both the arc-shaped protrusions 30 and the clamping block 24 are provided with rounded corners.

[0053] The discharge box has an opening at its lower end, and guide plates 20 are provided on both sides of the lower end of the discharge box. The guide plates 20 are fixed between the first housing 1 and the second housing 2. The guide plates 20 are inclined, with the lower end of the guide plate 20 tilted towards the other guide plate 20. There is a gap between the lower ends of the two guide plates 20 to allow the battery body 16 to pass through. The battery body 16 that detaches from the first turntable 17 falls between the two guide plates 20.

[0054] Working principle: Initially, under the action of spring 27, the clamping block 24 does not contact the two ends of the second slot 19.

[0055] In use, multiple sliding plates 26 are placed into the feeding funnel 3, and the battery body 16 enters the connecting box from the feeding funnel 3. The battery body 16 is arranged in a single row in the connecting box.

[0056] When the first motor 4 is started, the first turntable 17 rotates. When the first slot 18 engages with the feed inlet 32, the battery body 16 at the feed inlet 32 ​​rolls into the first slot 18. Then, as the first turntable 17 rotates, when the end of the first slot 18 away from the slot opening tilts downwards, the battery body 16 rolls down along the first slot 18 and falls into the second slot 19 near the slot opening. If the second slot 19 near the slot opening is occupied at this time, the battery body 16 will fall into the second second slot 19 from the slot opening inwards. If the second second slot 19 is also occupied, the battery body 16 will fall into the third second slot 19. When the clamping block 24 contacts the arc-shaped protrusion 30, the clamping block 24 gradually enters the arc-shaped protrusion 30 and slides along the arc-shaped protrusion 30. Under the action of the arc-shaped protrusion 30, the clamping block 24 moves closer to the battery body 16, and the sliding plate 26 moves closer to the electromagnet 28. Until the two clamping blocks 24 clamp and fix the battery body 16, the battery body 16, clamping blocks 24, electromagnet 28, and discharger 29 form a series circuit. If the battery body 16 is not fully discharged at this time, the discharger 29 will discharge the battery body 16. The electromagnet 28 generates magnetism when energized and attracts the sliding plate 26. After the clamping blocks 24 pass the arc-shaped protrusion 30, the electromagnet 28 attracts the sliding plate 26, keeping the two clamping blocks 24 clamping and fixing the battery body 16. At the same time, the electromagnet 28 also accelerates the discharge of the battery body 16.

[0057] If the battery body 16 is discharged, the electromagnet 28 is de-energized, and the sliding plate 26 moves away from the electromagnet 28 under the action of the spring 27, and the two clamping blocks 24 release their clamping and fixing of the battery body 16.

[0058] As the first turntable 17 rotates, when the end of the second slot 19 near the first slot 18 tilts downwards, if the battery body 16 has finished discharging, the clamping block 24 releases its grip on the battery body 16, and the battery body 16 falls from the second slot 19 into the first slot 18. When the end of the first slot 18 near the opening tilts downwards, the battery body 16 falls out of the first slot 18. If the battery body 16 has not finished discharging, the clamping block 24 maintains its grip on the battery body 16, and the battery body 16 remains in the second slot 19 and continues to discharge.

[0059] When the opening of the first slot 18 mates with the feed inlet 32 ​​again, the battery body 16 at the feed inlet 32 ​​rolls into the first slot 18 and falls into the second slot 19.

[0060] Accordingly, the first turntable 17 continues to rotate, and the battery body 16 in the feed hopper 3 sequentially enters the first slot 18 and then the second slot 19. When the battery body 16 has finished discharging, it will fall out of the second slot 19 and the first slot 18 as the first turntable 17 rotates. If the battery body 16 has not finished discharging, the clamping block 24 holds the battery body 16 in place, and the discharger 29 and electromagnet 28 continue to discharge the battery body 16, so that the battery body 16 in the feed hopper 3 enters another second slot 19.

[0061] It should be noted that since both the electromagnet 28 and the discharger 29 discharge the battery body 16, when all three second slots 19 within a first slot 18 contain battery bodies 16, the battery body 16 that first enters the first slot 18 will complete its discharge and detach from the first turntable 17 as it rotates. Thus, when the first slot 18 mates with the feed inlet 32 ​​again, the battery body 16 can enter the corresponding second slot 19 after entering the first slot 18.

[0062] Example 2: This example is an improvement based on Example 1.

[0063] A base plate 6 is provided below the discharge box, and the discharge box is fixedly mounted on the base plate 6 via a connecting plate 5. A fixing plate 8 is fixedly mounted on the base plate 6. A second turntable 21 is rotatably mounted between the two fixing plates 8. A second motor 7 is fixedly mounted on one of the fixing plates 8, and the motor shaft of the second motor 7 is drivenly connected to the second turntable 21.

[0064] The second turntable 21 has multiple third slots 22 spaced apart on its circumferential surface. The lower end of the guide plate 20 slides in engagement with the second turntable 21, and the battery body 16 falling from the two guide plates 20 falls into the third slots 22. The thickness of the second turntable 21 is less than the length of the battery body 16, so after the battery body 16 enters the third slots 22, both ends of the battery body 16 extend outside the second turntable 21.

[0065] Both ends of one side of the second turntable 21 are equipped with cutters 35. The cutters 35 are rotatably mounted on the fixed plate 8. Specifically, both ends of the second turntable 21 are coaxially fixedly connected to a large gear 33. Both cutters 35 are coaxially fixedly connected to a small gear 36, which meshes with the large gear 33 on the same side. The cutters 35 cut off the end of the battery body 16.

[0066] Limiting strips 34 are provided at both ends of the second turntable 21, and the limiting strips 34 are fixedly connected to the fixing plate 8. The position of the limiting strips 34 is set to match the position of the cutter 35. The limiting strips 34 limit the battery body 16 in the third slot 22 to prevent the battery body 16 from falling out of the third slot 22, so that the cutter 35 can cut the battery body 16.

[0067] A guide block 15 is provided on the base plate 6, and the guide block 15 is located on one side of the second turntable 21. After the cutter 35 finishes cutting the battery body 16, as the second turntable 21 continues to rotate, the battery body 16 falls off the limit bar 34 and onto the guide block 15 after it is released from the limit bar 34, and moves downward along the guide block 15.

[0068] A second limiting frame 13 is provided at the lower end of the guide block 15, and the second limiting frame 13 is set on the base plate 6. The base plate 6 is fixedly provided with an electric push rod 14 and a first limiting frame 12. The electric push rod 14 and the first limiting frame 12 are respectively located on both sides of the second limiting frame 13. Circular holes are opened on both sides of the second limiting frame 13, and the axes of the two circular holes are on the same axis. A top block 37 that matches the circular hole is fixed to the telescopic end of the electric push rod 14. The electric push rod 14 pushes the positive and negative electrode materials in the outer shell of the battery body 16 out of the outer shell and pushes them into the first limiting frame 12 through the top block 37.

[0069] A second discharge port is provided on the base plate 6, and a baffle 23 is rotatably installed at the discharge port. A third motor 38 is embedded in the base plate 6, and the third motor 38 is driven by the baffle 23. A second collection box 11 is placed below the second discharge port.

[0070] A first discharge port is provided on the base plate 6, which cooperates with the first limiting frame 12. A first collection box 10 is provided below the first discharge port. The positive and negative electrode materials entering the first limiting frame 12 enter the first collection box 10 through the first discharge port.

[0071] A third discharge port is provided on the base plate 6, which cooperates with the second turntable 21. A third collection box 9 is provided below the third discharge port, and the end of the battery body 16 cut off by the cutter 35 falls into the third collection box 9 for collection. Figure 12 , Figure 14 As shown, the third collection box 9 has an opening on one side. The third collection box 9 is placed on the base plate 6 from one side. The third collection box 9 partially surrounds the second turntable 6. The upper end of the third collection box 9 is higher than the height of the cutter 35. When the cutter 35 cuts the battery body 16, it is beneficial to collect the flying debris and prevent the debris from flying everywhere.

[0072] Working principle: When the second motor 7 is started, the second turntable 21 rotates. Under the action of the large gear 33 and the small gear 36, the cutter 35 rotates. The rotation direction of the cutter 35 is opposite to the rotation direction of the second turntable 21.

[0073] The battery body 16, falling from between the two guide plates 20, enters the third slot 22. As the second turntable 21 rotates, the limiting strip 34 limits the battery body 16, preventing it from detaching from the third slot 22. The second turntable 21 drives the battery body 16 to rotate. When the battery body 16 comes into contact with the cutter 35, the cutter 35 cuts the end of the battery body 16. The end of the battery body 16 cut off by the cutter 35 falls into the third collection box 9 through the third discharge port.

[0074] As the second turntable 21 rotates, the battery body 16 disengages from the limiting strip 34. The battery body 16, with its ends cut off, then falls from the third slot 22 onto the guide block 15, and moves downwards along the guide block 15 until it enters the second limiting frame 13. When the battery body 16 is within the second limiting frame 13, the electric push rod 14 is activated. The electric push rod 14 pushes the positive and negative electrode materials inside the battery body 16's casing through the top block 37, pushing the positive and negative electrode materials into the first limiting frame 12 and then into the first collection box 10 through the first discharge port. The outer casing of the battery body 16 remains within the second limiting frame 13, causing the electric push rod 14 to reset. Then, the third motor 38 is activated, the baffle 23 rotates, the second discharge port opens, and the outer casing of the battery body 16 falls into the second collection box 11. Afterwards, the baffle 23 resets to cover the second discharge port again.

[0075] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
