Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a crushing device for recycling waste lithium batteries. Background Art

[0002] In recent years, with the rise of a new round of energy revolution, many countries including China, Europe, the United States, Japan and South Korea have begun to vigorously develop new energy vehicles. The development of new energy vehicles has driven the growth of demand for lithium-ion batteries. A large number of discarded lithium batteries have been recycled. The recycling of waste lithium battery materials generally adopts physical crushing methods.

[0003] In the prior art, a crushing device for recycling waste lithium battery materials, such as that disclosed in patent CN220346092U, crushes the fragments that have not passed the screening on the screen plate, which can crush the waste lithium battery materials more efficiently, make the crushing more uniform, and do not need repeated crushing.

[0004] However, in the above technology, the material falling on the screen plate relies solely on its own gravity and the inclination of the screen plate to cause the material to fall into the crushing roller or cavity. When a large amount of material is processed in the shell, the material on the screen plate is prone to blockage, thereby affecting the crushing efficiency of the crushing roller; at the same time, the above technology can sweep the remaining fragments after metal adsorption onto the guide plate and enter the discharge port, but the metal adsorbed on the magnetic block is not cleaned up. When a large amount of metal is adsorbed, the outermost adsorbed metal is less affected by the magnetism and is prone to fall off the magnetic block and then fall into the guide plate, resulting in mixing of the separated materials. Utility Model Content

[0005] The utility model aims to solve the problems in the background technology and proposes a crushing device for recycling waste lithium batteries.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-3 A crushing device for recycling waste lithium batteries includes a kettle body 1, a telescopic block 5 is fixedly installed in the kettle body 1, a sieve plate 6 is slidably connected in the kettle body 1, and the sieve plate 6 is slidably connected to the telescopic block 5, a plurality of springs are arranged in the telescopic block 5, and the other end of each spring is installed on the sieve plate 6, and the setting of the spring facilitates the resetting of the sieve plate 6.

[0024] A feed port 2 is provided on the top surface of the kettle body 1, and a crushing device 3 is provided inside the kettle body 1. Since the crushing device 3 is a prior art, it will not be described again. A baffle 4 is fixedly installed on the crushing device 3, and the baffle 4 prevents a large amount of material from falling between the crushing rollers 8, so as to increase the crushing efficiency of the crushing rollers 8. A guide plate 7 is fixedly installed inside the kettle body 1, and crushing teeth are installed on the guide plate 7. Through the setting of the guide plate 7, even when the screen plate 6 is extended and retracted, the material that has not been crushed will not fall directly into the second conveying channel 12, but the material will be poured into the crushing rollers 8 through the guide plate 7 for crushing again. A plurality of crushing rollers 8 are provided in the kettle body 1.

[0025] The outside of the kettle body 1 is rotatably connected with a cam 13, and the cam 13 abuts against the screen plate 6. A synchronization mechanism is provided on one of the crushing rollers 8, and the synchronization mechanism is connected to the cam 13. The synchronization mechanism includes a rotating shaft, and the rotating shaft is rotatably connected to the outside of the kettle body 1, and the cam 13 is installed on the kettle body 1. Synchronous wheels 14 are installed on the rotating shaft and the crushing rollers 8 corresponding to the position. The two synchronous wheels 14 are jointly installed with a synchronous belt 15. Through the setting of the synchronous belt 15, the rotation speed of the cam 13 and one of the crushing rollers 8 is the same, and the cam 13 requires an additional power source, which reduces the use of motors and reduces the production cost of the device.

[0026] A conveyor belt 9 is provided in the kettle body 1, and the conveyor belt 9 rotates clockwise. The conveyor belt 9 is tilted and located below the sieve plate 6. A first conveying channel 11 and a second conveying channel 12 are fixedly installed in the kettle body 1, and both the first conveying channel 11 and the second conveying channel 12 are tilted. The width of the conveyor belt 9 is smaller than that of the second conveying channel 12, and the first conveying channel 11 is located below the conveyor belt 9.

[0027] A thermoplastic box 10 is provided inside the conveyor belt 9, and other iron products are prevented from interfering with the operation of the relay through the thermoplastic box 10. A plurality of high-current relays 16 are provided inside the thermoplastic box 10. By energizing the plurality of high-current relays 16, a strong magnetic field is generated, and the magnetic material in the material is adsorbed on the upper surface of the conveyor belt 9. Then, the conveyor belt 9 is tilted, and the non-magnetic material falls directly onto the second conveying channel 12, and the material containing the magnetic material rotates clockwise with the conveyor belt 9.

[0028] When the magnetic material moves to the end of the conveyor belt 9 and is no longer above the thermoplastic box 10, the magnetic field caused by the high-current relay 16 no longer affects the magnetic material, and it falls above the second conveying channel 12; then it rolls to the bottom of the second conveying channel 12 by gravity, and then when it passes directly below the conveyor belt 9, it is acted upon by the high-current relay 16 again, so that it is adsorbed on the conveyor belt 9; then when it passes the end of the conveyor belt 9 on the left, it falls into the first conveying channel 11 by gravity, thereby realizing the separation of magnetic and non-magnetic materials.

[0029] When the utility model is used, materials are put in through the feed port 2, and then the materials falling into the kettle body 1 are first crushed by the crushing device 3, and then when the crushed materials are smaller than the micro holes opened on the sieve plate 6, they directly fall onto the conveyor belt 9.

[0030] When the material is larger than the micropores on the screen plate 6, it falls into the crushing roller 8 for re-crushing. At the same time, the crushing roller 8 at the corresponding position is rotating, and synchronous wheels 14 are installed on the rotating shaft and the crushing roller 8, and the two synchronous wheels 14 are jointly sleeved with a synchronous belt 15, which drives the rotating shaft to rotate, and then drives the cam 13 to push the screen plate 6 to reciprocate in a short range, thereby accelerating the passing rate of the material on the screen plate 6 and preventing accumulation on the screen plate 6 to cause blockage.

[0031] At the same time, the high-current relay 16 is started, and the magnetic materials falling onto the conveyor belt 9 are adsorbed onto the conveyor belt 9, while the non-magnetic materials directly fall onto the second conveying channel 12 by their own gravity. Then, the conveyor belt 9 rotates clockwise, so that the magnetic materials on the conveyor belt 9 leave the top of the thermoplastic box 10 when passing the end of the conveyor belt 9, and the magnetic materials cannot be adsorbed onto the conveyor belt 9, and then fall into the first conveying channel 11, thereby realizing the separation of the crushed materials.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
