Description

Crushing device for processing lithium battery waste Technical Field

[0001] The present invention belongs to the technical field of lithium battery waste slag crushing, and more specifically, relates to a crushing device for processing lithium battery waste slag. Background Art

[0002] The lithium battery waste residue crushing device is a device specially used to handle and process lithium battery waste residue. Lithium battery waste residue refers to discarded or damaged lithium-ion batteries, including used batteries and waste generated during the production process. Lithium battery waste residue contains harmful chemicals and valuable metal resources, so it needs to be processed and recycled through a crushing device.

[0003] The Chinese patent publication number is: CN202321842137.2, which discloses a crushing device for recycling waste lithium battery materials. The crushing device for recycling waste lithium battery materials includes a shell, a motor, a crushing bin, an auger rod, a screen plate and a crushing roller. The shell has a feeding port on the upper wall. The screen plate is inclined toward one side of the crushing roller. The crushing roller is used to crush 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 require repeated crushing.

[0004] However, the above solution still has the following problems during implementation:

[0005] 1. During the implementation of the above scheme, the crushed materials are only screened by the sieve plate. When too much lithium battery waste residue is crushed at one time, the waste residue may accumulate on the sieve plate during the screening process, causing blockage and accumulation, affecting the smooth screening process and thus reducing the screening efficiency.

[0006] 2. The distance between the crushing bin and the sieve plate in the above scheme is fixed and the outlet of the crushing bin is small, which makes it more prone to blockage and accumulation. In addition, the fixed distance cannot be adjusted and cannot meet the needs of use. The characteristics and processing requirements of lithium battery waste may vary depending on the application scenario and subsequent processing method. By adjusting the distance, it can flexibly adapt to different processing needs.

[0007] 3. Lithium battery waste will vibrate during the crushing process. The lack of a shock-absorbing structure may have a negative impact on the performance and reliability of the device. Continuous vibration may cause fatigue and damage to equipment components, thereby shortening the life of the device and increasing maintenance and repair costs.

[0008] Therefore, in view of this, the existing structure and defects are studied and improved, and a crushing device for processing lithium battery waste is provided, in order to achieve a more practical purpose. Summary of the Invention

When the lithium battery waste needs to be crushed, the output shaft of the motor 5 is started to drive the gear 15 located in the front of the two gears 15 to rotate. During the rotation, the two gears 15 mesh with each other. At this time, the two crushing rollers 3 fixedly connected to the two gears 15 also rotate accordingly.

[0032] Working principle:

[0033] In the first step, when the lithium battery waste needs to be crushed, the motor 15 is started and its output shaft will drive the gear 15 located in the front of the two gears 15 to rotate. During the rotation process, the two gears 15 are meshed with each other. At this time, the two crushing rollers 3 fixedly connected to the two gears 15 also rotate accordingly. The two crushing rollers 3 rotate toward opposite sides to effectively crush the lithium battery waste. The crushed residue will fall into the screening box 9 arranged below for transportation. A screening mesh 17 is provided in the screening box 9, and the waste residue is screened by the screening mesh 17. The vibration motor 21 fixedly installed on the left side of the screening box 9 is started. The vibration motor 21 will drive the screening box 9 to vibrate. The screening box 9 is fixed to the fixed plate 8 through the connecting base 20 fixed thereunder. The connecting base 20 is tilted to make the screening box 9 tilt forward for convenience. The waste slag is transported, and the screening efficiency is improved by the vibration of the vibration motor 21, which facilitates the transportation of the waste slag. The front surface of the screening box 9 is fixedly connected to the limit rod 18 by a thread, and it can be disassembled by rotating the screws connected to the limit rod 18. After the limit rod 18 is disassembled, the screening mesh 17 opens the limit and can be replaced. According to actual needs, the screening meshes 17 of different apertures can be replaced to screen particles of different sizes in the lithium battery waste slag. After the replacement is completed, the limit is performed by the limit rod 18. The replaceable design facilitates the recycling of lithium battery waste slag. By replacing the screening meshes 17 of different apertures, the waste slag particle size can be graded to optimize the recycling efficiency. Larger particles may need to be further crushed, thereby minimizing the generation of waste and improving resource utilization, while smaller particles can be more easily recycled and processed.

[0034] In the second step, during crushing, it is necessary to flexibly adjust the distance between the crushing box 2 and the screening box 9 according to the on-site environment to meet the needs of use. Start the second motor 13 and its output shaft will drive the threaded rod 10 to rotate. During the rotation of the threaded rod 10, the connecting block 14 sleeved on its surface is subjected to the action of the thread to perform up and down translational movement. The connecting block 14 will drive the crushing box 2 to move together during the movement. Telescopic blocks 31 are provided on the left and right sides of the crushing box 2. The lower surfaces of the two telescopic blocks 31 are movably connected with fixed blocks 6. The two telescopic blocks 31 can ensure the stability of the crushing box 2 during movement. The change in the height of the crushing box 2 can be flexibly controlled by the second motor 13, so that the distance between the crushing box 2 and the screening box 9 can be adjusted as needed. The appropriate spacing can ensure that the waste slag is effectively transported to the collection device, reducing the leakage and scattering of the waste slag, which helps to improve the efficiency of waste slag recovery and utilization, and reduce the waste of resources. In addition, it can also reduce the dust generated during the crushing process, thereby improving the working environment and reducing secondary pollution.

[0035] In the third step, the vibration motor 21 used in the screening box 9 when screening the waste residue will vibrate the whole. The screening box 9 is arranged on the fixed plate 8 as a whole. A group of connecting shafts 12 are fixed on the opposite surfaces of the fixed plate 8 and the supporting base plate 1. The two groups of connecting shafts 12 are rotatably connected with connecting rods 11, and the two pairs of connecting rods 11 located at the bottom of the two groups of connecting rods 11 are both retractable. When the fixed plate 8 is subjected to the pressure generated by the vibration of the screening box 9, it will transfer it to the two groups of connecting rods 11. The two groups of connecting rods 11 are pressed close to each other and will drive the two pairs of extrusion blocks 7 to move toward the opposite surfaces. The two pairs of extrusion blocks 7 are slidably connected to the supporting base plate 1 through the limiting pulleys 29 connected thereto. When the two pairs of extrusion blocks 7 move, the two springs 27 arranged therein will be compressed, thereby slowing down the vibration force generated by the vibration motor 21, effectively reducing the vibration amplitude of the device, improving the stability and reliability of the device, thereby extending the service life of the device, and reducing the cost of maintenance and repair.
