Description

Technical Field

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

[0002] A lithium battery recycling unit is a specialized device for recycling and processing used lithium batteries. It typically uses specific technologies and processes to decompose, separate, recycle, and reuse used lithium batteries, achieving resource recycling and reducing environmental pollution. Recycling lithium batteries through a recycling unit not only recovers many valuable metal elements from the batteries, reducing the need for mining new resources and lowering production costs, but also ensures that these hazardous substances are properly disposed of, minimizing environmental pollution.

[0003] Existing recycling devices often lack stratified screening and recycling functions when crushing lithium batteries. As a result, some lithium battery fragments fail to reach the expected level of refinement and do not meet the standards for direct recycling. This not only affects recycling efficiency but also requires subsequent manual intervention, necessitating further screening and secondary crushing by staff. This process consumes considerable time and human resources, thus compromising the practicality of efficient and environmentally friendly lithium battery recycling devices.

[0004] Patent application number 202420073914.X discloses a lithium battery recycling device. This application connects a cover plate to a base device, and then rotates a crushing ring to allow the lithium battery to fall into the base device through the cover plate. The crushing ring then crushes the lithium battery, which falls into a recycling bin to complete the recycling. However, the device has the following problems: it cannot achieve layered filtering of lithium battery fragments, and it cannot repeatedly crush and recycle the fragments, thus failing to achieve a finer degree of fragmentation. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a highly efficient and environmentally friendly lithium battery recycling device that improves the fineness of lithium battery fragments and increases lithium battery recycling efficiency.

[0006] The objective of this utility model can be achieved through the following technical solution: a highly efficient and environmentally friendly lithium battery recycling device, comprising a recycling bin with an inlet and an outlet, and further comprising:

[0007] The crushing assembly, located inside the recycling bin, includes two opposing crushing rollers for crushing lithium batteries entering through the feed inlet.

[0008] A filter assembly is located below the crushing assembly. The filter assembly performs solid-liquid separation on the crushed lithium battery, and the solid fragments are discharged from the outlet into the recycling bin.

[0009] A drive assembly, mounted on the recycling bin, provides the driving force for the rotation of the crushing roller.

[0010] As a further embodiment of this invention, the driving component includes:

[0011] The upper rotating shaft has two ends that are rotatably connected to the two side walls of the recycling bin, and one end of the upper rotating shaft passes through the side wall of the recycling bin and is connected to the drive rod of the drive motor.

[0012] Two drive shafts are connected to crushing rollers. The two ends of the two drive shafts are rotatably connected to the two side walls of the recycling box. One end of each drive shaft passes through the side wall of the recycling box and is connected to a drive gear. The drive shaft closer to the upper rotating shaft transmits power to the upper rotating shaft through the first transmission belt. The two drive gears mesh with each other and drive the two crushing rollers to rotate in opposite directions.

[0013] As a further embodiment of this invention, the filtering component includes:

[0014] The first filter plate has its edge connected to the inner wall of the recycling bin, and the first filter plate is inclined and set inside the recycling bin.

[0015] The second filter plate is inclined and located below the first filter plate. The edge of the second filter plate is connected to the inner wall of the recovery box. The recovery box wall at the lower end of the inclined second filter plate has a discharge port.

[0016] The filter holes of the first filter plate are larger than those of the second filter plate.

[0017] As a further embodiment of this invention, the crushing component further includes:

[0018] Two guide plates are located at the top of the two crushing rollers and are connected to the inner wall of the recycling box, arranged in a relatively inclined manner.

[0019] As a further embodiment of this utility model, a feeding shaft is provided at the feeding port, with both ends of the feeding shaft rotatably connected to the side wall of the feeding port. One end of the feeding shaft passes through the side wall of the feeding port and is connected to a drive shaft via a second transmission belt to form a power transmission. The feeding shaft is connected to multiple feeding plates, and the feeding plates are adapted to the inner wall of the feeding port when they rotate.

[0020] As a further embodiment of this utility model, it also includes a material recycling component, which comprises:

[0021] The lower rotating shaft is rotatably connected to the two side walls of the recycling box at both ends. Both the upper and lower rotating shafts are connected to rotating wheels. The two rotating wheels are connected to the power transmission through the conveyor belt. Multiple material holding plates are connected to the outside of the conveyor belt. When the material holding plates rotate with the conveyor belt, they bring the large pieces at the bottom of the first filter plate back to the guide plate.

[0022] A limiting plate is provided, with its two sides connected to the inner wall of the recycling bin and its upper end connected to the edge of the guide plate. The limiting plate isolates the space between the recycling assembly and the crushing assembly.

[0023] As a further embodiment of this utility model, a filtrate inlet is provided on the bottom side wall of the recycling tank, and a pull-out filtrate collection box is provided through the filtrate inlet. The filtrate collection box is located below the second filter plate and collects the filtered electrolyte.

[0024] As a further embodiment of this utility model, a material collecting plate is connected to the outer side of the bottom edge of the discharge port.

[0025] The beneficial effects of this utility model are:

[0026] 1.

[0027] 2. This utility model utilizes a conveyor belt and multiple material holding plates within the recycling bin to allow lithium battery fragments that have not reached the desired fineness, selected from the first filter plate, to be transported back to the crushing area between two crushing rollers for secondary crushing. This ensures that the fragments meet the ideal particle size requirements, significantly improving the efficiency of lithium battery recycling and ensuring the quality of recycled materials. Furthermore, it effectively reduces the need for manual screening and secondary crushing, saving valuable time and human resources, thus enhancing the practicality of this efficient and environmentally friendly lithium battery recycling device.

[0028] 3. This utility model, by setting multiple rotatable feeding plates in the feeding box, can not only transport lithium batteries to the recycling box, but also significantly prevent lithium batteries from being broken by the crushing roller and causing fragments to fly. This not only optimizes the lithium battery recycling process, but also reduces the hazards that lithium batteries may cause during the recycling process, making the use of the efficient and environmentally friendly lithium battery recycling device safer.

[0038] The embodiments of this utility model are described in detail below. Examples of the embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] like Figure 1 As shown, this utility model discloses a high-efficiency and environmentally friendly lithium battery recycling device, including a recycling box 10 with an inlet 11 and an outlet 12. The recycling box 10 is equipped with a crushing component 100, a filtering component 200, a driving component 300, and a return component 400.

[0040] The drive assembly 300 is mounted on the recycling bin 10 and provides the driving force for the rotation of the crushing roller 110.

[0041] Specifically, such as Figure 2 As shown, the drive assembly 300 includes components such as an upper rotating shaft 310, two drive shafts 360, and a drive motor 320. The two ends of the upper rotating shaft 310 are rotatably connected to the two side walls of the recycling bin 10, and one end of the upper rotating shaft 310 passes through the side wall of the recycling bin 10 and is connected to the drive rod of the drive motor 320.

[0042] The main body of the two drive shafts 360 is located inside the recycling box 10. The two drive shafts 360 are respectively connected to the crushing rollers 110. The two ends of the two drive shafts 360 are respectively rotatably connected to the two side walls of the recycling box 10. One end of the two drive shafts 360 passes through the side wall of the recycling box 10 and is respectively connected to the drive gears 330. The drive shaft 360 closer to the upper rotating shaft 310 forms a power transmission with the upper rotating shaft 310 through the first transmission belt 340. The two drive gears 330 mesh with each other, thereby driving the two crushing rollers 110 to rotate in opposite directions.

[0043] In use, the drive motor 320 provides driving force, which drives the upper rotating shaft 310 to rotate. The upper rotating shaft 310 drives a drive shaft 360 to rotate through the first transmission belt 340. The drive shaft 360 drives the other drive shaft 360 to rotate in the opposite direction through two meshing drive gears 330. As a result, the crushing rollers 110 on the two drive shafts 360 rotate towards each other to crush the lithium batteries that have entered the recycling bin 10.

[0044] The crushing assembly 100 is located inside the recycling bin 10. The crushing assembly 100 includes two crushing rollers 110 rotating in opposite directions and two guide plates 120. The two guide plates 120 are located at the upper ends of the two crushing rollers 110 and are connected to the inner wall of the recycling bin 10. They are arranged in a relatively inclined manner and are funnel-shaped. When the lithium battery enters the recycling bin 10, it can be effectively moved between the two crushing rollers 110 by the convergence of the two guide plates 120, thereby effectively crushing it.

[0045] The filtration assembly 200 includes components such as a first filter plate 210 and a second filter plate 220, and components such as a pull-out filtrate collection box 240.

[0046] The first filter plate 210 is located below the crushing roller 110. The edge of the first filter plate 210 is connected to the inner wall of the recycling box 10. The first filter plate 210 is inclinedly arranged in the recycling box 10. After the lithium battery entering the recycling box 10 is crushed by the crushing roller 110, the small fragments of the lithium battery and the electrolyte fall through the filter holes of the first filter plate 210. The large fragments slide down the inclined surface of the first filter plate 210 to the lower end, are collected by the return material assembly 400, and are returned to the upper side of the crushing roller 110 for further crushing.

[0047] The second filter plate 220 is inclined and located below the first filter plate 210. The filter holes of the second filter plate 220 are smaller than those of the first filter plate 210. The edge of the second filter plate 220 is connected to the inner wall of the recycling box 10. The recycling box 10 wall at the inclined lower end of the second filter plate 220 has a discharge port 12. The second filter plate 220 receives small lithium battery fragments and electrolyte that fall from the first filter plate 210. The small fragments slide down the inclined surface of the first filter plate 210 to the lower discharge port 12, and are collected and processed after sliding out of the discharge port 12 to the collection plate 230.

[0048] The bottom side wall of the recovery tank 10 is provided with a filtrate inlet 13, and a pull-out filtrate collection tank 240 is provided through the filtrate inlet 13. The filtrate collection tank 240 is located below the second filter plate 220. After the electrolyte is filtered by the second filter plate 220, it falls into the filtrate collection tank 240. The filtrate collection tank 240 collects the filtered electrolyte. When the filtrate collection tank 240 is full of electrolyte, the collection tank is pulled out of the recovery tank 10 for subsequent processing of the electrolyte.

[0049] Inside the recycling bin 10, at the lower edge of the first filter plate 210, there is also a material return assembly 400, which includes components such as a lower rotating shaft 410 and a limiting plate 440.

[0050] The lower rotating shaft 410 is used in combination with the upper rotating shaft 310. The two ends of the lower rotating shaft 410 are rotatably connected to the two side walls of the recycling box 10. Both the upper rotating shaft 310 and the lower rotating shaft 410 are connected to a rotating wheel 420. The two rotating wheels 420 form a power transmission through the outer conveyor belt 450. Multiple material holding plates 430 are connected to the outer side of the conveyor belt 450.

[0051] A limiting plate 440 is also provided between the recycling component 400 and the crushing component 100. The two sides of the limiting plate 440 are connected to the inner wall of the recycling box 10, and the upper end of the limiting plate 440 is connected to the edge of the guide plate 120. Large pieces on the first filter plate 210 can enter the recycling area of ​​the recycling component 400 through the lower end of the limiting plate 440. The limiting plate 440 isolates the recycling component 400 and the crushing component 100 into relatively independent spaces.

[0052] When the material holding plate 430 rotates in a cycle following the conveyor belt 450, it brings the large pieces at the lower end of the first filter plate 210 back to the upper side of the guide plate 120, where they are collected by the guide plate 120 and continue to be crushed by the crushing roller 110.

[0053] Furthermore, the lower end of the first filter plate 210 is shaped to match the shape of the material holding plate 430 when it rotates, making it easier for the material holding plate 430 to bring the large pieces at the lower end of the first filter plate 210 back to the upper side of the guide plate 120.

[0054] Furthermore, such as Figure 3 As shown, a feed shaft 130 is also provided at the feed inlet 11. The two ends of the feed shaft 130 are rotatably connected to the side wall of the feed inlet 11. One end of the feed shaft 130 passes through the side wall of the feed inlet 11 and forms a power transmission with a drive shaft 360 through the second transmission belt 350. The feed shaft 130 is connected to multiple feed plates 140. When the feed plates 140 rotate, they are adapted to the inner wall of the feed inlet 11.

[0055] By setting multiple rotatable feed plates 140 inside the feed inlet 11, the lithium battery is conveyed to the recycling bin 10 while preventing the lithium battery from being broken by the crushing roller 110 and causing fragments to fly. This optimizes the lithium battery recycling process and reduces the potential hazards of lithium batteries during recycling.

[0056] The principle of this utility model:

[0057] When the drive motor 320 is started, the lithium battery is placed on the multiple feed plates 140 in the feed inlet 11. The drive rod of the drive motor 320 will drive the upper rotating shaft 310 to rotate. The upper rotating shaft 310 can drive a nearby drive shaft 360 to rotate through the first transmission belt 340. The two drive shafts 360 are meshed through the drive gear 330. One drive shaft 360 drives the other drive shaft 360 to rotate in the opposite direction, thereby driving the two crushing rollers 110 to rotate in opposite directions to crush the lithium battery.

[0058] The drive shaft 360 on the side away from the upper rotating shaft 310 can drive the feed shaft 130 to rotate via the second transmission belt 350. The feed shaft 130 will drive the multiple feed plates 140 on the outer side to rotate, thereby transporting the lithium batteries to be recycled into the recycling bin 10. When the lithium batteries enter the recycling bin 10, they will move between the two crushing rollers 110 under the action of the two guide plates 120. The two relatively rotating crushing rollers 110 crush the lithium batteries. The crushed lithium battery fragments will fall onto the first filter plate 210. Smaller lithium battery fragments will pass through the first filter plate 210. The filter plate 210 falls onto the second filter plate 220 and is then discharged through the outlet 12. Larger lithium battery fragments move to the lower end of the first filter plate 210. When the upper rotating shaft 310 and the lower rotating shaft 410 rotate, they drive the conveyor belt 450 and multiple material holding plates 430 to rotate, thereby transporting the large lithium battery fragments on the first filter plate 210 to the upper end of the two crushing rollers 110, where the two crushing rollers 110 further crush and process them, ensuring that the lithium batteries meet the ideal particle size requirements, thus making the efficient and environmentally friendly lithium battery recycling device more practical.
