Electrode slurry preparation machine for lithium battery production

Abstract

The invention discloses an electrode slurry preparation machine for lithium battery production. The electrode slurry preparation machine comprises a base, wherein two brackets are fixedly mounted at the top of the base; the same preparation cylinder is fixedly mounted on the two brackets; a feeding hopper and a motor are fixedly mounted at the top of the preparation cylinder; the bottom end of the feeding hopper extends into the preparation cylinder; a rotating shaft is arranged in the preparation cylinder; a first through hole is formed in the inner wall of the top of the preparation cylinder; the top end of the rotating shaft penetrates through the first through hole and is fixedly connected with the output shaft end of the motor; three U-shaped rods are arranged on the rotating shaft; and the three U-shaped rods are rotationally sleeved with sleeves. The electrode slurry preparation machine is reasonable in design and good in practicability and can fully and rapidly stir and mix raw materials; the stirring and mixing of the raw materials are more uniform; the stirring quality and the stirring efficiency of the raw materials are improved; in the process of discharging, a knocking ball and a discharging pipe are used for intermittent collision to generate vibration force, so the raw materials are not prone to adhering to the pipe wall of the discharging pipe, the blockage of the discharge pipe hardly occurs, and smooth discharging can be realized.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to an electrode slurry preparation machine for lithium battery production. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. In the production process of lithium batteries, the first step in the production of lithium batteries is the preparation of electrode slurry. Electrode active materials, bonding Agents, solvents, etc. are mixed together and fully stirred to form a slurry. [0003] However, in the prior art, when the commonly used electrode slurry preparation machine is ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an electrode slurry preparation machine for lithium battery production, which solves the problem of uneven stirring and mixing of raw materials when the existing electrode slurry preparation machine is in use, and the agitation and mixing of raw materials The effect is not good, and it takes a long time to stir and mix the raw materials, resulting in poor stirring quality of the raw materials, low stirring efficiency of the raw materials, and during the discharge process, the raw materials are easy to stick to the inner wall of the discharge pipe , it is easy to cause the blockage of the discharge pipe, resulting in the problem that the discharge work cannot be carried out smoothly
