Description

Technical Field

[0001] This invention relates to the field of battery recycling technology, specifically to a battery electrode stripping and conveying device and system with a variable tilt angle. Background Technology

[0002] With the rapid development of new energy vehicles and the energy storage industry, the recycling of spent lithium batteries has become a crucial link in ensuring resource circulation and environmental protection. Dry recycling processes are widely used in the recycling of spent lithium batteries due to their advantages such as low energy consumption, no secondary pollution, and high resource recovery rates. In the dry recycling process, after crushing and screening, the battery electrode materials need to be separated from the current collectors (copper foil and aluminum foil) using a stripping device. The separated active material and current collectors are then subjected to further recycling processes.

[0003] In the dry recycling process, the product after processing by the stripping equipment mainly consists of two parts: one is the active material powder stripped from the current collector, and the other is current collector fragments still attached with some residual active material. Currently, the stripped current collector fragments are generally directly transported to the subsequent current collector recycling process via conveying equipment. However, during the conveying and transfer process, especially during falling, collisions, and equipment vibrations, the fine active material powder attached to the surface of the current collector fragments with residual powder is easily detached and dispersed into the air, generating dust. This not only pollutes the working environment, affecting safe production and employee health, but also leads to the loss of valuable materials (active material), reducing the overall recovery rate. Summary of the Invention

[0004] The purpose of this invention is to provide a battery electrode stripping and conveying device and system with a variable tilt angle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a variable tilt angle battery electrode stripping and conveying device, comprising a support frame, on which a closed conveyor is rotatably mounted, and further comprising: The feed box is fixedly installed on the enclosed conveyor, and the feed box has a feed channel, a cylindrical cavity and a discharge channel. A rotating tube is rotatably disposed within the cylindrical cavity; An adsorption mechanism, disposed on the rotating tube, is used to adsorb residual powder on the current collector fragments; A disturbance mechanism, disposed on the rotating tube, is used to break up the debris in the collector. The adsorption mechanism includes multiple filter covers arranged circumferentially along the rotating tube, and a powder suction pipe connected to the filter covers; when the rotating tube rotates, it drives the filter covers and the disturbance mechanism to move synchronously.

[0006] Preferably, the powder suction pipeline includes a connecting pipe communicating with the filter cover, and a connecting long pipe communicating with multiple filter covers through the connecting pipe; The connecting tube is equipped with a sealing component, which is used to alternately seal or open its own opening according to the position of the connecting tube inside the rotating tube.

[0007] Preferably, the sealing assembly includes a drive gear rotatably mounted on the connecting tube, and toothed plates meshing on both sides of the drive gear; Each of the two toothed plates has a sliding rod fixedly connected to one end of each other, and the two sliding rods slide through the limiting block fixed on the connecting tube respectively. The two sliding rods are respectively fixedly connected to a movable column and a conical block at their ends that are far apart from each other. The conical block is used to block the opening of the connecting tube. A return spring is fitted on the sliding rod connected to the moving column. One end of the return spring abuts against the end face of the connecting block on the moving column, and the other end abuts against the limiting block.

[0008] Preferably, it further includes a fixing column fixedly installed on the feed box by a fixing frame, the fixing column extending into the interior of the rotating tube and rotatably connected to the rotating tube, a fixing plate fixed on the fixing column, and a limiting semicircular ring located in the lower half of the fixing plate. The end of the movable column is provided with a rolling ball. When the connecting long tube rotates with the rotating tube to the lower half of its inner cavity, the rolling ball contacts the inclined surface of the limiting semicircular ring and is radially limited by it, driving the sealing component to act so that the conical block seals the opening of the connecting long tube.

[0009] Preferably, the disturbance mechanism includes a first bevel gear fixedly mounted on the fixed column; The first bevel gear meshes with a second bevel gear, and a rotating rod is fixedly connected to the end of the second bevel gear. The rotating rod is rotatably connected to the inside of the rotating tube through a fixed bracket. The portion of the rotating rod extending out of the rotating tube is fixedly provided with multiple sets of fixing rods.

[0010] Preferably, it also includes a drive assembly for adjusting the tilt angle of the enclosed conveyor; The drive assembly includes a first support plate and a second support plate fixed on the support frame, a sliding rod and a threaded rod fixed between the two, and a movable seat threadedly connected to the threaded rod and slidably connected to the sliding rod; A push plate is hinged to the movable seat, and the end of the push plate away from the movable seat is hinged to the enclosed conveyor. The threaded rod is driven by a first motor fixed to the support frame.

[0011] Preferably, a first gear is fixedly mounted on the rotating tube, the first gear meshes with a second gear, and the second gear is driven by a second motor mounted on the feed box via a bracket.

[0012] Preferably, one end of the rotating tube is connected to a funnel tube, and the funnel tube is connected to a connecting pipe through a rotary joint. The connecting pipe is used to connect to an external negative pressure device.

[0013] Preferably, the feeding channel is connected to the feeding end of the enclosed conveyor, and a feeding hopper is connected to the feeding channel.

[0014] A variable tilt angle battery electrode stripping and conveying system includes the aforementioned variable tilt angle battery electrode stripping and conveying device; and The control unit is electrically connected to the first motor, the second motor, and the external negative pressure device of the drive assembly, and is used to coordinate the control of the tilt angle of the conveying device, the rotation speed of the rotating tube, and the start and stop of the adsorption negative pressure.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention effectively solves the dust problem during the conveying of fragments after stripping by using a rotating tube and its adsorption and disturbance mechanisms installed in the feed box. When the fragments enter the rotating tube area from the feed hopper through the feed channel, the fixed rod of the disturbance mechanism can continuously break up the clumps of fragments, fully exposing the active material powder attached to their surface. At the same time, the filter cover of the adsorption mechanism directly absorbs and collects the exposed powder under the suction force provided by the external negative pressure equipment, realizing active dust suppression and material recovery from the source of conveying, reducing the loss of valuable materials and improving the working environment.

[0016] 2. The adsorption mechanism of this invention is ingeniously designed. Through the cooperation of the sealing component and the upper limit semicircular ring of the fixed plate, the adsorption function is automatically opened and closed. When the connecting tube rotates to the upper part with the rotating tube, its opening opens, and negative pressure is applied to the filter cover to adsorb powder. When it rotates to the lower part, the rolling ball at the end of the moving column is squeezed by the upper limit semicircular ring, driving the conical block to seal the opening of the connecting tube, and the adsorption stops. This allows the fragments to detach under gravity and fall into the enclosed conveyor through the feeding channel.

[0017] 3. The feed hopper is directly connected to the enclosed conveyor, allowing the collected debris falling from the rotating tube discharge channel to directly and completely enter the enclosed conveying environment. The entire conveying path from the feed hopper to the discharge port of the enclosed conveyor is within a sealed or negative pressure adsorption chamber, preventing dust from escaping due to spillage, collision, or airflow disturbance during the transfer and conveying process, further ensuring the cleanliness of the working environment and the complete recovery of materials.

Detailed Implementation

[0032] 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.

[0033] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Please see Figures 1 to 13This invention provides a technical solution: a variable tilt angle battery electrode stripping conveying device, including a support frame 1, the top of which is rotatably connected to a closed conveyor 3 through a rotating connector, ensuring that the tilt angle of the closed conveyor 3 can be adjusted around the connection point. A drive component 2 is fixedly installed on the support frame 1 to drive the closed conveyor 3 to complete the angle adjustment. The closed conveyor 3 adopts a mature closed belt conveyor in the prior art. Its main structure, transmission principle and conveying function are all conventional designs, which can realize the closed conveying of materials and avoid dust leakage during the conveying process. The conveyor belt of the conveyor is provided with baffles at intervals along its length. The baffles are the anti-drop structure commonly used in the prior art for conveyor belts. The first support plate 22 and the second support plate 23 are fixed parallel to each other on the corresponding brackets of the support frame 1. The sliding rod 25 and the threaded rod 26 are fixedly connected at both ends to the first support plate 22 and the second support plate 23, respectively, and the sliding rod 25 and the threaded rod 26 are parallel to each other.

[0035] The movable seat 24 is simultaneously fitted onto the sliding rod 25 and the threaded rod 26, with a sliding fit with the sliding rod 25 and a threaded fit with the threaded rod 26. One end of the push plate 27 is hinged to the movable seat 24 via a hinge shaft, and the other end is hinged to the bottom frame of the enclosed conveyor 3 via another hinge shaft. One end of the threaded rod 26 passes through the second support plate 23 and is fixedly connected to the output shaft of the first motor 21 fixed on the support frame 1 via a coupling. The forward and reverse rotation of the first motor 21 drives the threaded rod 26 to rotate, thereby causing the movable seat 24 to slide back and forth along the sliding rod 25. Finally, the push plate 27 pushes the enclosed conveyor 3 to deflect around the rotation connection point, thereby adjusting the tilt angle. This angle adjustment structure is stable and reliable, and can accurately adapt to the conveying height and subsequent equipment docking requirements of different on-site working conditions.

[0036] like Figure 6 As shown, the feed box 4 is fixedly installed on the feed end of the enclosed conveyor 3 by bolts, and the two remain relatively fixed. The feed box 4 is integrally formed with a feed channel 41, a cylindrical cavity 42 and a discharge channel 43, which form a connected material channel inside the feed box 4. The upper opening of the feed channel 41 is fixedly connected to the feed hopper 8 by a flange, which is used to receive the collected fragments conveyed by the external stripping equipment. The lower opening of the discharge channel 43 is aligned with and fixedly connected to the feed port of the feed end of the enclosed conveyor 3, ensuring that the processed collected fragments can fall smoothly into the enclosed conveyor 3. The cylindrical cavity 42 is a cylindrical cavity used to install the rotating tube 5.

[0037] like Figure 4As shown, the rotating tube 5 is rotatably disposed within the cylindrical cavity 42, and its two ends are rotatedly engaged with the corresponding side walls of the feed box 4 via bearings to ensure smooth rotation. The first gear 12 is fixedly mounted on one end of the extended section of the rotating tube 5 by a flat key. The second motor 13 is fixedly mounted on the outer side wall of the feed box 4 by a bracket. The second gear 14 is fixedly mounted on the output shaft of the second motor 13, and the second gear 14 meshes with the first gear 12. The second motor 13 drives the second gear 14 to rotate, thereby driving the first gear 12 and the rotating tube 5 to rotate synchronously, providing stable power for the rotation of the rotating tube 5.

[0038] like Figure 5 As shown, the fixing frame 15 is welded and fixed to the outer wall of the feed box 4 on the side away from the first gear 12. One end of the fixing column 16 is welded and fixed to the fixing frame 15, and the other end extends horizontally into the interior of the rotating tube 5. The fixing column 16 and the rotating tube 5 are rotatably connected through a sealed bearing to ensure that the fixing column 16 remains stationary when the rotating tube 5 rotates. An isolation plate 17 is also fixedly installed inside the rotating tube 5. The isolation plate 17 is coaxially arranged with the rotating tube 5 and welded and fixed to the inner wall of the rotating tube 5. The end of the fixing column 16 away from the fixing frame 15 is rotatably connected to the center hole of the isolation plate 17 through a bearing, further improving the support stability of the fixing column 16.

[0039] like Figure 8 As shown, the adsorption mechanism 6 is mounted on the rotating tube 5 and is used to adsorb residual powder on the current collector fragments. The adsorption mechanism 6 includes multiple filter covers 61, connecting tubes 62, connecting long tubes 63, and sealing components. The multiple filter covers 61 are evenly distributed along the circumference of the rotating tube 5, and each filter cover 61 is fixed to the outer wall of the rotating tube 5 by bolts. One end of the connecting tube 62 communicates with the inside of the filter cover 61, and the other end communicates with the connecting long tube 63. The connecting tube 62 is sealed and fixedly connected to the rotating tube 5 and the connecting long tube 63. The connecting long tube 63 is arranged along the axial direction of the rotating tube 5, passes through the isolation disk 17, and is sealed and fixedly connected to the isolation disk 17 to ensure that the connecting long tube 63 can rotate synchronously when the rotating tube 5 rotates.

[0040] like Figures 8 to 11As shown, the sealing assembly is mounted on the connecting long pipe 63, used to alternately seal or open its opening according to the position of the connecting long pipe 63 within the rotating pipe 5. A drive gear 611 is rotatably mounted on the outer wall of the connecting long pipe 63. Two toothed plates 610 mesh with the upper and lower sides of the drive gear 611, with the two toothed plates extending in opposite directions. One end of each of the two sliding long rods 68 is welded and fixed to the ends of the two toothed plates 610 that are far apart from each other. Two limiting blocks 67 are welded and fixed to the outer wall of the connecting long pipe 63, and the two sliding long rods 68 slide through their respective limiting blocks 67. The limiting blocks 67 guide and limit the sliding direction of the sliding long rods 68. The moving column 64 and the conical block 612 are welded and fixed to the ends of the two sliding long rods 68 that are far apart from each other via connecting blocks 66. The conical surface of the conical block 612 faces the opening end of the connecting long pipe 63, used to seal the opening of the connecting long pipe 63.

[0041] The return spring 69 is sleeved on the sliding long rod 68 connected to the moving column 64. One end of the spring abuts against the end face of the connecting block 66, and the other end abuts against the end face of the limiting block 67. Under normal conditions, under the elastic action of the return spring 69, the conical block 612 is in a state away from the opening of the connecting long tube 63, so that the opening is kept open. The return spring 69 is made of 65Mn spring steel, which is a mature material in the existing technology. This material has excellent elastic limit, fatigue strength and toughness, and can adapt to the long-term high-frequency telescopic reset conditions of the equipment.

[0042] like Figure 10 As shown, the adsorption mechanism 6 also includes a fixed disk 613 and a limiting semicircular ring 614. The fixed disk 613 is fixedly mounted on the fixed column 16 by a flat key and is located inside the rotating tube 5. The limiting semicircular ring 614 is welded and fixed to the fixed disk 613 and is located in the lower half of the fixed disk 613. An inclined surface is provided on the limiting semicircular ring 614. A rolling ball 65 is embedded at the end of the movable column 64. When the connecting tube 63 rotates with the rotating tube 5 to the lower half of the inner cavity of the rotating tube 5, the rolling ball 65 contacts the inclined surface of the limiting semicircular ring 614 and is radially limited by it, pushing the movable column 64 to move to one side of the connecting tube 63. Then, through the toothed plate 610, it drives the drive gear 611 to rotate, causing the sliding rod 68 on the other side to move in the opposite direction, so that the conical block 612 blocks the opening of the connecting tube 63. When the connecting tube 63 rotates to the upper half of the inner cavity of the rotating tube 5, the rolling ball 65 is released from the constraint of the limiting semicircular ring 614. Under the elastic reset action of the return spring 69, the conical block 612 moves away from the opening, and the opening reopens.

[0043] like Figure 12 as well as Figure 13As shown, the disturbance mechanism 7 is also installed on the rotating tube 5 to disperse the collected debris, fully exposing any remaining powder. The first bevel gear 71 is fixedly mounted on the fixed column 16 via a flat key and is located inside the rotating tube 5. The second bevel gear 72 meshes with the first bevel gear 71. One end of the rotating rod 73 is fixedly connected to the central axis of the second bevel gear 72. The fixed bracket 74 is fixed to the inner wall of the rotating tube 5 by bolts. The rotating rod 73 is rotatably connected to the fixed bracket 74 via a bearing, ensuring that the second bevel gear 72 can rotate stably. The end of the rotating rod 73 away from the second bevel gear 72 extends out of the tube wall of the rotating tube 5. Multiple sets of fixed rods 75 are evenly welded and fixed around this extended section, and each set of fixed rods 75 is positioned between two adjacent filter covers 61 to ensure the dispersion effect on the collected debris. Since the fixed column 16 remains stationary, when the rotating tube 5 rotates, the second bevel gear 72 rotates along with the rotating tube 5 and rotates on its own axis under the meshing action of the first bevel gear 71, thereby driving the fixed rod 75 to rotate synchronously, so as to continuously disperse the fragments of the collector.

[0044] One end of the rotating tube 5 near the first gear 12 is connected to one end of the funnel tube 9 through a flange. The other end of the funnel tube 9 is connected to the connecting tube 11 through a rotary joint 10. The connecting tube 11 is used to connect to an external negative pressure device, which can be a dust collector. The rotary joint 10 ensures that the funnel tube 9 and the connecting tube 11 remain stably connected when the rotating tube 5 rotates, avoiding pipe entanglement or leakage.

[0045] This embodiment also discloses a variable tilt angle battery electrode stripping and conveying system. The system includes the aforementioned variable tilt angle battery electrode stripping and conveying equipment and a control unit. The control unit is a PLC controller, which is electrically connected to the first motor 21, the second motor 13 of the drive assembly 2, and the external negative pressure device via wires. It is used to coordinate the control of the tilt angle of the conveying equipment, the rotation speed of the rotating tube 5, and the start and stop of the negative pressure adsorption. The first motor 21 is a servo motor, whose rotation angle can be precisely controlled by the control unit to achieve precise adjustment of the conveying angle. The second motor 13 is a variable frequency motor, whose speed can be adjusted by the control unit to adapt to different material conveying requirements. The start and stop of the external negative pressure device is linked to the second motor 13 to ensure continuous and effective negative pressure adsorption during material processing. It should be noted that the enclosed conveyor 3, PLC controller, servo motor, variable frequency motor, rotary joint 10, etc., are all mature and common components in the prior art, and their specific structures and working principles will not be described in detail here.

[0046] First, adjust the conveying angle according to the on-site working conditions. Adjust the tilt angle of the enclosed conveyor 3 through the drive component 2. Start the first motor 21 to drive the threaded rod 26 to rotate, which drives the moving seat 24 to slide along the sliding rod 25. Then, through the push plate 27, push the enclosed conveyor 3 to deflect around its rotational connection point with the support frame 1, thereby adapting to different conveying heights and subsequent equipment docking.

[0047] During conveying, the second motor 13 and the external negative pressure device connected to the connecting pipe 11 are started. The second motor 13 drives the second gear 14 to rotate, which in turn drives the rotating pipe 5 to rotate continuously within the cylindrical cavity 42 of the feed box 4 through meshing with the first gear 12. The external negative pressure device establishes negative pressure inside the rotating pipe 5 through the connecting pipe 11, the rotary joint 10, and the funnel pipe 9.

[0048] The collector fragments are slowly fed into the feed channel 41 of the feed box 4 through the feed hopper 8 and fall into the rotating tube 5. The fragments rotate together with the rotating tube 5 and the filter cover 61 mounted on it, and are gradually conveyed from the upper side to the lower side of the rotating tube 5. During this process, the disturbance mechanism 7 works synchronously. Since the fixed column 16 remains stationary, the first bevel gear 71 on it meshes with the second bevel gear 72. When the rotating tube 5 drives the second bevel gear 72 to revolve, the second bevel gear 72 rotates under the action of the first bevel gear 71, and drives multiple sets of fixed rods 75 to rotate through the rotating rod 73. The fixed rods 75 are located between adjacent filter covers 61, continuously breaking up the collector fragments, fully exposing the encapsulated residual powder, and preventing the fragments from clumping together.

[0049] The adsorption mechanism 6 simultaneously adsorbs powder. Each filter hood 61 is connected to the connecting tube 63 via a connecting pipe 62. The sealing component on the connecting tube 63 automatically controls its opening and closing according to its position. When the connecting tube 63 rotates with the rotating tube 5 to the upper half of the inner cavity of the rotating tube 5, the rolling ball 65 at the end of the moving column 64 disengages from the limiting semi-circular ring 614 on the fixed plate 613. Under the elastic force of the return spring 69, the conical block 612 moves away from the opening of the connecting tube 63, and the opening opens. At this time, negative pressure acts on the filter hood 61 through the connecting tube 63 and the connecting pipe 62, sucking in the residual powder exposed on the surface of the fragments. After being filtered by the filter hood 61, the powder is drawn into the negative pressure system and finally enters the external negative pressure equipment for recovery through the funnel tube 9, the rotary joint 10, and the connecting pipe 11.

[0050] When the connecting tube 63 rotates with the rotating tube 5 to the lower half of the inner cavity of the rotating tube 5, the rolling ball 65 at the end of the moving column 64 contacts the inclined surface of the limiting semicircular ring 614 and is radially limited by it, pushing the moving column 64 to move towards the side of the connecting tube 63. Through the transmission of the toothed plate 610 and the drive gear 611, the conical block 612 moves towards the opening of the connecting tube 63 and blocks it. At this time, the negative pressure adsorption function of the connecting tube 63 is turned off, preventing the fragments from still adhering to the filter cover 61 due to negative pressure adsorption when the fragments rotate with the rotating tube 5 and the filter cover 61 to the lower side for unloading. This makes it easier for the fragments to smoothly detach from the filter cover 61 under the action of gravity and fall into the closed conveyor 3 through the unloading channel 43.

[0051] Because the rotating tube 5 is equipped with multiple sets of filter covers 61 and corresponding connecting tubes 63, which rotate cyclically with the rotating tube 5, one part of the connecting tubes 63 is in the upper half for powder adsorption while the other part of the connecting tubes 63 is in the lower half for material discharge, thus achieving synchronous and continuous operation of powder cleaning and material discharge. The cleaned dust collector fragments enter the enclosed conveyor 3 and are transported to the subsequent process, effectively preventing dust generation.
