New energy automobile lithium battery cell slurry processing and stirring equipment

Abstract

The invention discloses new energy automobile lithium battery cell slurry processing and stirring equipment which comprises a stirring tank, wherein supporting legs and a discharging pipe are arranged at the bottom of the stirring tank, a feeding pipe is arranged on the side wall, which is close to the top, of the stirring tank, a rotatable outer rotating cylinder is embedded in the top of the stirring tank, an inner rotating cylinder is rotationally connected to the inner side of the outer rotating cylinder, the top of the stirring tank is provided with a driving mechanism used for driving the outer rotating cylinder and the inner rotating cylinder to synchronously and reversely rotate, the bottom of the outer rotating cylinder and the bottom of the inner rotating cylinder are both provided with material leaking holes, the stirring tank is internally provided with a material scraping frame fixedly connected with the outer rotating cylinder, the center of the bottom of the inner rotating cylinder is fixedly connected with a sleeve penetrating out of the outer rotating cylinder, and the lower side of the sleeve is connected with an inner stirring mechanism. According to the invention, stirring can be more sufficient, formation of dead zones of lithium battery cell slurry is reduced, powder particle groups can be sufficiently crushed, and the slurry stirring efficiency and the mixing effect are greatly improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a new energy vehicle lithium battery cell slurry processing and stirring equipment. Background technique [0002] With the rapid development of new energy vehicles in recent years, the demand for lithium batteries used in new energy vehicles has also increased significantly. In the production of lithium batteries, the stirring of cell slurry is a mixing and dispersing process that is important in the entire production process of lithium-ion batteries. The influence degree of product quality is greater than 30%, which is the most important link in the whole production process. [0003] However, the existing lithium battery cell slurry stirring device is often fixed stirring, that is, the stirring area of ​​the stirring rod is limited, the material on the edge of the stirring barrel is not easy to be stirred, the fluidity of the slurry is poor, and it is easy to produce...

Problems solved by technology

[0003]However, the existing lithium battery cell slurry stirring device is often fixed stirring, that is, the stirring area of ​​the stirring rod is limited, and the material on the edge of the stirring barrel is not easy to be After stirring, the fluidity of the slurry is poor, and it is easy to produce the so-called "dead zone", and the existing stirring rod has a single stirring direction, and the stirred cell slurry will generate inertia and rotate in the same direction as the stirring rod, further reducing the Stirring efficiency. At the same time, some powdery raw materials need to be added to the stirring of the cell slurry. When the powdery raw materials are added to the slurry, it is easy to produce powder lumps because they cannot be fully dispersed. However, it is difficult for the traditional stirring rod to quickly and fully mix the powder lumps. Therefore, the stirring efficiency is low, and the effect of stirring and mixing is not ideal.
