Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling technology, and in particular to a high-efficiency lithium battery recycling device. Background Technology

[0002] High-efficiency lithium battery recycling equipment, as a key device for realizing the recycling of lithium battery resources, plays an important role in addressing the increasing volume of scrapped lithium batteries and alleviating resource shortages and environmental pollution. In the lithium battery recycling process, the screening stage is crucial, responsible for classifying the crushed lithium battery residue according to particle size so that different components can be recycled in subsequent stages. This stage typically uses the following structure:

[0003] 1. Screen: As the core component of screening, it is responsible for screening the particle size of lithium battery residue. Its material, pore size and weaving method directly affect the screening effect.

[0004] 2. Support structure: Provides stable support for the screen, ensuring that the screen remains in a fixed position during operation, while also withstanding the vibration and impact generated during equipment operation.

[0005] 3. Vibration device: By generating vibration, the lithium battery residue on the screen continuously jumps and tumbles, increasing the chance of particles passing through the screen holes and improving screening efficiency.

[0006] Currently, various equipment and technologies are employed in the industry to improve the efficiency and quality of the screening process. Some companies use planar vibrating screens, which use a motor to drive an eccentric block to generate vibration, causing the material to move in a straight line or curve on the screen surface, thus achieving screening. Other companies use circular vibrating screens, which utilize the circular motion generated by the vibrator to make the material move forward in a spiral shape on the screen mesh, achieving the screening purpose. In addition, some advanced screening equipment is equipped with an automated control system that can monitor and adjust screening parameters in real time.

[0007] However, the above-described implementation still has the following problems. During the screening process, lithium battery residue easily clogs the screen holes, leading to reduced screening efficiency and increased equipment maintenance costs. Due to the lack of an effective stirring and cleaning mechanism, the material on the screen is difficult to distribute evenly, which not only affects the screening accuracy but also causes some material to fail to pass through the screen in time and accumulate on the screen surface. To address this problem, this application proposes a solution that optimizes the screening process in the high-efficiency lithium battery recycling equipment by adding a cleaning mechanism, thereby effectively improving screening efficiency, ensuring that the screen remains clean at all times, improving screening accuracy, reducing equipment maintenance frequency and costs, and ensuring stable and efficient recycling operations. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a high-efficiency lithium battery recycling device that solves the problem of lithium battery residue easily clogging the screen holes, leading to reduced screening efficiency and increased equipment maintenance costs. Due to the lack of an effective stirring and cleaning mechanism, the material on the screen is difficult to distribute evenly, which not only affects the screening accuracy but also causes some material to be unable to pass through the screen in time and accumulate on the screen surface.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A high-efficiency lithium battery recycling device includes a crusher, a screen inside the crusher, a connecting plate above the screen, two agitating rods below the connecting plate, a bracket fixedly connected to the upper surface of the connecting plate, a connecting block fixedly connected to the front surface of the bracket, synchronous gears fixedly connected to the upper surfaces of the two agitating rods, both synchronous gears being rotatably connected to the connecting plate, a synchronous belt provided on the annular side of the two synchronous gears, the connecting block being movably connected to the crusher, a storage box inside the crusher, a scraper movably connected inside the crusher, a fixing plate fixedly connected to the inner wall of the crusher, a lead screw rotatably connected between the fixing plate and the crusher, a second servo motor fixedly mounted on the upper surface of the connecting plate, and the output shaft of the second servo motor being fixedly connected to the rightmost synchronous gear among the two synchronous gears.

[0011] Preferably, a protective plate is fixedly connected to the upper surface of the connecting plate, a cylinder is fixedly installed on the front surface of the crusher, and the cylinder output shaft is fixedly connected to the connecting block.

[0012] Preferably, a guide plate is fixedly installed on the front surface of the crusher, and a servo motor is fixedly installed on the front surface of the fixed plate. The output shaft of the servo motor is fixedly connected to a lead screw, and the lead screw is threadedly connected to the scraper.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The two stirring rods can stir the lithium battery residue by rotating, which can make the lithium battery residue more evenly distributed on the screen, avoid local accumulation, and allow lithium battery residue of different particle sizes to pass through the corresponding screen holes more accurately according to their size, thereby improving the screening accuracy and making the particle size of the screened product more uniform. This is beneficial for the subsequent classification, processing and recycling of materials of different particle sizes.

[0015] 2. By starting the servo motor, its output shaft drives the fixed lead screw to rotate. During the rotation of the lead screw, the scraper sleeved on it moves due to the screw thread. The scraper reciprocates on the screen, which effectively scrapes off the lithium battery residue on the screen, preventing the accumulation of lithium battery residue, ensuring the screen's permeability, and maintaining a good screening effect. In addition, timely cleaning of the lithium battery residue on the screen avoids long-term compression and wear of the screen by the lithium battery residue, thereby extending the screen's service life.

[0022] This application provides a high-efficiency lithium battery recycling device that effectively solves the problem of lithium battery residue clogging the screen holes, leading to reduced screening efficiency and increased equipment maintenance costs. Due to the lack of an effective stirring and cleaning mechanism, the material on the screen is difficult to distribute evenly, which not only affects the screening accuracy but also causes some material to fail to pass through the screen in time and accumulate on the screen surface. The high-efficiency lithium battery recycling device optimizes the screening process and adds a cleaning mechanism, thereby effectively improving screening efficiency, ensuring that the screen is always kept clean, improving screening accuracy, reducing the frequency and cost of equipment maintenance, and ensuring stable and efficient recycling operations.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that lithium battery residue easily clogs the screen holes, leading to reduced screening efficiency and increased equipment maintenance costs. Furthermore, due to the lack of an effective agitation and cleaning mechanism, the material on the screen is difficult to distribute evenly, affecting screening accuracy and causing some material to accumulate on the screen surface instead of passing through in time. The overall approach is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a high-efficiency lithium battery recycling device, including a crusher 1. A screen 2 is installed inside the crusher 1, a connecting plate 6 is installed above the screen 2, and two agitator rods 7 are installed below the connecting plate 6. A bracket 16 is fixedly connected to the upper surface of the connecting plate 6, and a connecting block 12 is fixedly connected to the front surface of the bracket 16. Synchronous gears 13 are fixedly connected to the upper surfaces of both agitator rods 7, and both synchronous gears 13 are rotatably connected to the connecting plate 6. A synchronous belt 14 is installed on the annular side of the two synchronous gears 13. The connecting block 12 is movably connected to the crusher 1. A storage box 4 is installed inside the crusher 1, and a scraper 8 is movably connected inside the crusher 1. A fixing plate 10 is fixedly connected to the inner wall of the crusher 1, and a lead screw 11 rotatably connects the fixing plate 10 and the crusher 1. A servo motor 17 is fixedly installed on the upper surface of the connecting plate 6, and the output shaft of the servo motor 17 is fixedly connected to the right synchronous gear 13 of the two synchronous gears 13. During use, the decomposed lithium battery is fed into the crusher 1 for crushing. After crushing, the lithium battery residue falls onto screen 2 for screening. To improve screening efficiency, the piston of cylinder 5 is activated, which drives the fixed connecting block 12 and support 16 to move together. At this time, the connecting plate 6 fixed to support 16 drives the two stirring rods 7 below to move together. The two stirring rods 7 move downward and contact the lithium battery residue. At this time, the output shaft of servo motor 17 is activated, which drives the fixed synchronous gear 13 to rotate. The synchronous belt 14 engaged with synchronous gear 13 will also rotate and drive the synchronous gear 13 on the other side to rotate together. The stirring rods 7 fixed to the two synchronous gears 13 will also rotate. The rotation of the two stirring rods 7 can stir the lithium battery residue, thereby making the lithium battery residue more evenly distributed on screen 2, avoiding local accumulation, and allowing lithium battery residue of different particle sizes to have more opportunities to accurately pass through the corresponding screen holes according to their size, thereby improving the screening accuracy and making the particle size of the screened product more uniform. This is beneficial for the subsequent classification, processing and recycling of materials of different particle sizes.

[0026] A protective plate 15 is fixedly connected to the upper surface of the connecting plate 6. A cylinder 5 is fixedly installed on the front surface of the crusher 1. The output shaft of the cylinder 5 is fixedly connected to the connecting block 12. A guide plate 3 is fixedly installed on the front surface of the crusher 1. A servo motor 9 is fixedly installed on the front surface of the fixed plate 10. The output shaft of the servo motor 9 is fixedly connected to the lead screw 11. The lead screw 11 is threadedly connected to the scraper 8. By starting the servo motor 9, its output shaft will drive the fixed lead screw 11 to rotate. During the rotation of the lead screw 11, the scraper 8 sleeved on it will move accordingly due to the thread action. The scraper 8 reciprocates on the screen 2. This movement can effectively scrape off the lithium battery residue remaining on the screen 2, avoid the accumulation of lithium battery residue, ensure the permeability of the screen 2, and maintain a good screening effect. In addition, by cleaning the lithium battery residue on the screen 2 in a timely manner, the long-term compression and wear of the lithium battery residue on the screen 2 are avoided, thereby extending the service life of the screen 2.

[0027] Among them, crusher 1 is used to crush the decomposed lithium batteries and provide crushed lithium battery residue for subsequent screening.

[0028] Screen 2: It is responsible for screening the particle size of the crushed lithium battery residue and is the core component of the screening process;

[0029] Guide plate 3: Installed on the front surface of crusher 1, it can guide the material and assist in the discharge of the material;

[0030] Storage bin 4: Located inside crusher 1, used to store lithium battery residue collected after screening;

[0031] Cylinder 5: Its output shaft is fixed to the connecting block 12. By extending and retracting, it drives the connecting block 12, thereby adjusting the position of the stirring rod 7.

[0032] Connecting plate 6: connects the stirring rod 7 and the bracket 16, and drives the stirring rod 7 to move under the action of the cylinder 5, providing support for it;

[0035] Servo motor 9: Its output shaft drives the lead screw 11 to rotate, providing power for the movement of the scraper 8 and realizing the function of cleaning the screen 2;

[0036] Fixed plate 10: Fixed to the inner wall of crusher 1, providing support for screw 11 so that it can rotate stably;

[0037] Lead screw 11: Driven by servo motor 9, it rotates and drives scraper 8 to move on screen 2 through the thread action;

[0038] Connecting block 12: connects cylinder 5 and bracket 16, transmits power from cylinder 5, and moves bracket 16 and related components;

[0039] Synchronous gear 13: fixed to the stirring rod 7, driven by servo motor 17, and realizes synchronous rotation of the two stirring rods 7 through synchronous belt 14;

[0040] Synchronous belt 14: connects two synchronous gears 13 to ensure that the two synchronous gears 13 rotate synchronously, so that the stirring rod 7 moves in unison;

[0041] Protective plate 15: Fixed to the upper surface of connecting plate 6, it serves a protective function to prevent foreign objects from entering the equipment and affecting its operation;

[0044] Working principle:

[0045] During use, the decomposed lithium batteries are fed into the crusher 1 for crushing. The crushed lithium battery residue falls onto the screen 2 for screening. To improve screening efficiency, the piston of the cylinder 5 is activated, which moves the fixed connecting block 12 and the support 16 together. At this time, the connecting plate 6 fixed to the support 16 moves the two stirring rods 7 below. The two stirring rods 7 move downward and contact the lithium battery residue. At this time, the output shaft of the servo motor 17 is activated, which drives the fixed synchronous gear 13 to rotate. The synchronous belt 14 engaged with the synchronous gear 13 also rotates and drives the synchronous gear 13 on the other side to rotate. The stirring rods 7 fixed to the two synchronous gears 13 also rotate. The rotation of the two stirring rods 7 can agitate the lithium battery residue, thereby making the lithium battery residue pass through the screen. The distribution on the screen 2 is more uniform, avoiding local accumulation. This allows lithium battery residue of different particle sizes to pass through the corresponding screen holes more accurately according to their size, thereby improving the screening accuracy and making the screened product more uniform in particle size. This is beneficial for subsequent classification, processing and recycling of materials of different particle sizes. By starting the servo motor 9, its output shaft will drive the fixed lead screw 11 to rotate. During the rotation of the lead screw 11, the scraper 8 sleeved on it will move due to the screw thread. The scraper 8 will reciprocate on the screen 2. This movement can effectively scrape off the lithium battery residue remaining on the screen 2, avoiding the accumulation of lithium battery residue, ensuring the permeability of the screen 2, and maintaining a good screening effect. In addition, by cleaning the lithium battery residue on the screen 2 in a timely manner, the long-term compression and wear of the lithium battery residue on the screen 2 are avoided, thereby extending the service life of the screen 2.

[0046] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
