Description

Technical Field

[0001] This utility model belongs to the field of waste recycling technology, specifically relating to a lithium battery cathode waste recycling and processing equipment. Background Technology

[0002] Waste lithium batteries contain a large amount of non-renewable and economically valuable metal resources. The positive electrode material of lithium batteries is lithium cobalt oxide powder, and the negative electrode material is graphite powder. Both the positive and negative electrode materials contain a large amount of metal materials such as nickel, copper, and aluminum. If waste or substandard lithium batteries can be effectively recycled and processed, it can not only reduce the pressure of waste batteries on the environment, but also avoid the waste of metal resources such as cobalt and nickel. The positive electrode powder and aluminum in lithium batteries can be recycled. However, the current recycling equipment is inefficient and the purity of the recycled materials is not high.

[0003] Existing lithium battery cathode waste recycling equipment typically uses a shredder to break the waste into smaller pieces, followed by a crusher to further pulverize it into smaller particles for subsequent screening. Currently, the crusher primarily relies on internal rotating blades for pulverization. However, because most lithium battery cathode waste is flaky and hard, clogging or incomplete pulverization can easily occur during crushing. This not only reduces recycling efficiency but also results in some incompletely pulverized material being discharged, increasing the difficulty of subsequent screening due to uneven pulverization.

[0004] Therefore, it is of great importance to design a lithium battery cathode waste recycling and processing equipment to solve the above-mentioned defects. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lithium battery cathode waste recycling and processing equipment. This equipment aims to solve the technical problems of easy recycling and processing of lithium battery cathode waste under the existing technology, which is prone to material blockage or incomplete crushing. This not only reduces the recycling and processing efficiency, but also increases the difficulty of subsequent screening processes due to uneven crushing.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a lithium battery cathode waste recycling and processing equipment. The equipment includes a feeder, a shredder, an elevator, and a crusher connected in sequence. The crusher includes a frame located behind the elevator. A discharge box is fixedly installed at the rear end of the frame. A crushing box is rotatably connected to the top of the discharge box. A receiving cover is rotatably connected to the top of the crushing box and located at the rear end of the elevator. A filter screen is fixedly installed at the bottom of the discharge box. A crushing blade shaft is rotatably connected inside the discharge box and located inside the filter screen. Multiple sets of main crushing blades are fixedly installed on the outside of the crushing blade shaft. Secondary crushing blades are fixedly installed inside the discharge box and located on both the front and rear sides of the filter screen.

[0009] When using the equipment of this technical solution, the lithium battery positive electrode waste is first loaded into the inner side of the feeder and conveyed to the shredder to be crushed into smaller pieces. The crushed lithium battery positive electrode waste is then fed into the receiving hopper through the downward-sloping discharge hopper, and then conveyed to the crusher by the elevator for crushing. The crushed lithium battery positive electrode waste is then fed into the crushing box through the receiving hood. The drive motor is started and drives the crushing blade shaft to rotate at high speed through the pulley set for crushing. Because the internal space of the crushing box and the receiving hood is large and deep enough, there is enough space during the crushing process. When the crushing blade shaft rotates at high speed, the lithium battery positive electrode waste can also move and collide with each other for crushing. At the same time, multiple sets of main crushing blades and auxiliary crushing blades are used in combination. After crushing, the particle size of the lithium battery positive electrode waste can be discharged through the filter screen. Moreover, both the crushing box and the receiving hood of the crusher can be opened for easy inspection, maintenance and cleaning after blockage.

[0010] Preferably, a feeding hopper is fixedly installed on the top of the front end of the feeding machine, a conveyor belt is fixedly installed inside the feeding machine, baffles are fixedly connected to both the left and right ends of the outer side of the conveyor belt, and multiple sets of lifting plates are fixedly connected between the two sets of baffles.

[0011] Furthermore, a discharge hopper is fixedly installed at the bottom of the shredder, and a receiving hopper is fixedly installed at the front end of the elevator, with the top of the receiving hopper connected to the bottom of the discharge hopper.

[0012] Furthermore, a discharge plate is fixedly installed at the bottom of the discharge box, and an inspection door is rotatably connected to the front of the discharge box.

[0013] Furthermore, the front end of the crushing box is rotatably connected to the discharge box via a first rotating shaft, and the rear end of the crushing box is fixedly connected to the discharge box via a first locking bolt.

[0014] Furthermore, the rear end of the receiving hood is rotatably connected to the crushing box via a second rotating shaft, and the front end of the receiving hood is fixedly connected to the crushing box via a second locking bolt.

[0015] Furthermore, a drive motor is fixedly installed at the front end of the frame, and the drive end of the drive motor is connected to the crushing blade shaft through a pulley set. A protective cover is fixedly installed on the right side of the frame, outside the pulley set.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes a design that integrates a receiving hood, a filter screen, a crushing blade shaft, and main and auxiliary crushing blades. When crushing lithium battery cathode waste, the crushing blade shaft rotates at high speed. Because the internal space of the crushing chamber and receiving hood is sufficiently large and deep, ample space is provided during the crushing process. This allows the lithium battery cathode waste to move and collide with each other during high-speed rotation of the crushing blade shaft, preventing material blockage and further improving crushing efficiency. Simultaneously, the use of multiple sets of main and auxiliary crushing blades ensures that the crushed lithium battery cathode waste particles are small enough to pass through the filter screen, guaranteeing uniform crushing and reducing the difficulty of subsequent screening processes. Furthermore, both the crushing chamber and receiving hood can be opened for easy inspection, maintenance, and cleaning after blockage, improving the ease of use of the equipment.

[0027] This specific embodiment is a lithium battery positive electrode waste recycling and processing device, the structural schematic diagram of which is shown below. Figure 1-7 As shown, the equipment includes a feeder 1, a shredder 2, an elevator 3, and a crusher 4 connected in sequence. The crusher 4 includes a frame 5 located behind the elevator 3. A discharge box 6 is fixedly installed at the rear end of the frame 5. A crushing box 7 is rotatably connected to the top of the discharge box 6. A receiving cover 8 is rotatably connected to the top of the crushing box 7 and located at the rear end of the elevator 3. A filter screen cylinder 9 is fixedly installed at the bottom end of the discharge box 6. A crushing blade shaft 10 is rotatably connected inside the discharge box 6 and located inside the filter screen cylinder 9. Multiple sets of main crushing blades 11 are fixedly installed on the outside of the crushing blade shaft 10. Auxiliary crushing blades 12 are fixedly installed inside the discharge box 6 and located on both the front and rear sides of the filter screen cylinder 9.

[0028] First, a feeding hopper 101 is fixedly installed on the top of the front end of the feeding machine 1. A conveyor belt 102 is fixedly installed inside the feeding machine 1. Baffle plates 103 are fixedly connected to both ends of the outer side of the conveyor belt 102. Multiple sets of lifting plates 104 are fixedly connected between the two sets of baffle plates 103. The lithium battery positive electrode waste is loaded into the inner side of the feeding machine 1 through the feeding hopper 101, and then conveyed by the conveyor belt 102. During the conveying process, the baffle plates 103 restrict the left and right sides to prevent it from falling out and reducing the conveying efficiency. Finally, the lithium battery positive electrode waste is lifted and conveyed to the shredder 2 by the lifting plates 104 and crushed into smaller pieces.

[0029] Furthermore, a discharge hopper 201 is fixedly installed at the bottom of the shredder 2, and a receiving hopper 301 is fixedly installed at the front end of the elevator 3. The top of the receiving hopper 301 is connected to the bottom of the discharge hopper 201. The crushed lithium battery positive electrode waste is introduced into the receiving hopper 301 by the downwardly inclined discharge hopper 201, and then conveyed to the crusher 4 by the elevator 3 for crushing.

[0030] Then, a discharge plate 601 is fixedly installed at the bottom of the discharge box 6, and an inspection door 602 is rotatably connected to the front of the discharge box 6. The lithium battery positive electrode waste, which is crushed into granules, is finally discharged through the discharge plate 601. The inspection door 602 on the front of the discharge box 6 can be opened to facilitate internal inspection and maintenance.

[0031] Furthermore, the front end of the crushing box 7 is rotatably connected to the discharge box 6 via the first rotating shaft 701, and the rear end of the crushing box 7 is fixedly connected to the discharge box 6 via the first locking bolt 702. After the first locking bolt 702 is operated to release the fixation of the crushing box 7, the crushing box 7 can be opened, so that the crushing blade shaft 10 and the filter screen cylinder 9 are exposed, which is convenient for inspection and maintenance.

[0032] Secondly, the rear end of the receiving cover 8 is rotatably connected to the crushing box 7 via the second rotating shaft 801, and the front end of the receiving cover 8 is fixedly connected to the crushing box 7 via the second locking bolt 802. After the second locking bolt 802 is operated to release the fixing of the receiving cover 8, the receiving cover 8 can be opened, which makes it convenient to clean its interior in case of material blockage.

[0033] Finally, a drive motor 1001 is fixedly installed at the front end of the frame 5. The drive end of the drive motor 1001 is connected to the crushing blade shaft 10 via a pulley assembly. A protective cover 1002 is fixedly installed on the right side of the frame 5, outside the pulley assembly. When crushing lithium battery cathode waste, the drive motor 1001 is started to drive the crushing blade shaft 10 to rotate at high speed via the pulley assembly for crushing. Since the internal space of the crushing box 7 and the receiving cover 8 is large and deep enough, there is enough space during the crushing process. When the crushing blade shaft 10 rotates at high speed, the lithium battery cathode waste can also move and collide with each other for crushing. This avoids material blockage and further improves the crushing efficiency. At the same time, by using multiple sets of main crushing blades 11 and auxiliary crushing blades 12 in cooperation, the particle size of the crushed lithium battery cathode waste can pass through the filter screen 9 before being discharged, thereby ensuring the uniformity of crushing and reducing the difficulty of subsequent screening processes.

[0034] When using the equipment of this technical solution, the lithium battery positive electrode waste is first loaded into the inner side of the feeder 1, and then conveyed to the shredder 2 by the feeder 1 to be crushed into smaller pieces. The crushed lithium battery positive electrode waste is then fed into the receiving hopper 301 through the downwardly inclined discharge hopper 201, and then conveyed to the crusher 4 by the elevator 3 for crushing. The crushed lithium battery positive electrode waste is then fed into the crushing box 7 through the receiving cover 8. The drive motor 1001 is started to drive the crushing blade shaft 10 to rotate at high speed through the pulley set to perform the crushing operation. Since the internal space of the crushing box 7 and the receiving cover 8 is large and deep enough, sufficient space is left during the crushing process. During the high-speed rotation of the crushing blade shaft 10, the lithium battery positive electrode waste materials can also move and collide with each other for crushing. At the same time, multiple sets of main crushing blades 11 and auxiliary crushing blades 12 work together to ensure that the particle size of the crushed lithium battery positive electrode waste materials can pass through the filter screen 9 before being discharged. Moreover, the crushing box 7 and the receiving cover 8 of the crusher 4 can be opened for easy inspection, maintenance and cleaning after material blockage. The entire operation process is simple and convenient. This utility model improves the crushing efficiency while avoiding material blockage, ensures the uniformity of crushing, reduces the difficulty of subsequent screening processes, and improves the ease of use of the equipment.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
