Description

Technical Field

[0001] The utility model relates to the technical field of material crushing, in particular to low-pressure crushing equipment for lithium battery ternary materials. Background Art

[0002] During the production and processing of ternary lithium batteries, various raw materials need to be processed through a series of processes, including material crushing. When crushing lithium battery ternary materials, corresponding low-pressure crushing equipment is required;

[0003] In the process of crushing lithium battery ternary materials, the existing low-pressure crushing equipment will not only crush the materials into particles, but also leave some material powder. The existing equipment does not have the function of removing the existing powder materials, so a subsequent filtering process is required, which is troublesome to operate and affects the processing efficiency. In addition, the surface of the crushing roller is prone to adhere to small particles, and long-term adhesion is likely to affect the crushing effect of the material. Therefore, we propose a low-pressure crushing equipment for lithium battery ternary materials. Utility Model Content

[0006] By adopting the above technical solution, the grass to be crushed is introduced into the inner cavity of the crushing box, and the material is crushed by two crushing rollers. Then the crushed material is introduced into the discharge shell, and then the material will roll along the surface of the guide plate. During the rolling of the material, the exhaust fan is started to generate negative pressure in the filter box, so that the hollow guide plate can generate negative pressure, so that the powdered raw material can pass through the filter mesh plate and be collected into the filter box, so that the powdered material can be directly removed during discharge without subsequent processing, thereby improving the processing efficiency.

[0007] As a preferred embodiment of the utility model, an air pump is fixedly installed on one side wall of the crushing box, and air nozzles are fixed on both side walls of the inner cavity of the crushing box. The output end of the air pump penetrates the crushing box through an air pipe and is fixedly connected to the air nozzle.

[0008] By adopting the above technical solution, when the crushing roller is used to crush the material, starting the air pump can generate gas to enter the air nozzle, so that the crushed materials adhering to the surface of the crushing roller can be blown away.

[0009] As a preferred embodiment of the present utility model, a vibration motor is fixed to the bottom of the guide plate.

[0010] By adopting the above technical solution, the vibration motor can drive the guide plate to vibrate, thereby preventing the material from being retained on the guide plate. At the same time, the vibration can cause the powder raw materials adhered to the surface of the granular material to be shaken off, thereby further improving the effect of removing the powder material.

[0014] By adopting the above technical solution and setting the filter screen, the powdery material can be retained in the filter box, thereby avoiding entering the exhaust fan and affecting it.

[0015] As a preferred embodiment of the present utility model, the top of the crushing box is fixedly connected to a feed hopper.

[0016] By adopting the above technical solution and setting the feed hopper, the material to be crushed can be introduced between the two crushing rollers.

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

[0018] The technical solution of the present application is a low-pressure crushing device for lithium battery ternary materials. The crushed granular materials enter the discharge shell and roll on the guide plate. At the same time, the exhaust fan can be started during the rolling of the materials to generate negative pressure in the filter box, so that the hollow guide plate can generate negative pressure, so that the powdered raw materials can pass through the filter screen plate and be collected into the filter box, so that the powdered materials can be directly removed during the discharge without subsequent processing, thereby improving the processing efficiency.

[0019] The vibration motor can drive the guide plate to vibrate, thereby preventing the material from being retained on the guide plate. At the same time, the vibration can shake off the powder raw materials adhering to the surface of the granular material, thereby further improving the effect of removing the powder material;

[0020] The air pump can generate gas to introduce the air nozzle, so that the crushing roller can use the gas to blow toward the crushing roller when crushing the material, so as to blow away the raw materials adhering to the crushing roller, thereby avoiding long-term adhesion of the material affecting the crushing effect.
