Description

A lithium battery slurry stirring device

technical field

The utility model relates to the field of lithium battery manufacturing equipment, in particular to a stirring device for the lithium battery.

Background technique

At present, the lithium battery button battery slurry is mainly stirred and dispersed by an electric mixer. This electric mixer is named as a two-bladed paddle mixer, a three-bladed paddle mixer, a four-bladed paddle mixer, etc. according to the number of blades of the agitator. It is also named according to the shape of the leaves. These paddles can achieve different stirring effects. However, due to the lithium battery button battery slurry, there is little slurry, the slurry container is a small glass, the slurry is stirred, and the stirring container is open for stirring. Therefore, the stirring of the existing electric mixer is prone to slurry splashing, which leads to differences in the proportion of the slurry, and finally leads to differences in the electrical property test of the material. In addition, in order to avoid excessive splashing of the slurry, it is necessary to reduce the stirring rate, thereby prolonging the time of slurry mixing, resulting in time-consuming. It usually takes 30 minutes to 2 hours to stir the lithium battery button electric slurry with this kind of mixer.

Utility model content

Aiming at the above-mentioned shortcomings of the prior art, the applicant conducts research and improvement, and provides a lithium battery slurry stirring device, which has the characteristics of fast stirring speed, high efficiency and good effect.

In order to solve the above problems, the utility model adopts the following scheme:

A lithium battery slurry stirring device, including a stirring paddle installed in a container, the stirring paddle is driven by a motor above the container, and a stirring cover with a reverse opening is installed in the container, and the stirring cover is connected to the The stirring paddle is movably connected, and its side wall is symmetrically provided with multiple slurry inlets and outlets.

As a further improvement of the above technical solution:

There is a certain gap between the inner wall of the stirring cover and the paddle of the stirring paddle, and there is a certain gap between the lower end surface of the stirring cover and the bottom surface of the container; the slurry inlet and outlet include four, and the width range is 0.3 -0.5cm, its height range is 1.2-1.5cm.

The technical effect of the utility model is:

The utility model can not only prevent the slurry from splashing, and there is no need to worry about any damage to the slurry container by the agitator, but also can quickly disperse the slurry to achieve simple, rapid and accurate slurry mixing.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model will be further described.

As shown in Figure 1, the lithium battery slurry stirring device of this embodiment includes a stirring paddle 2 installed in a container 1, the stirring paddle 2 is driven by a motor 3 above the container 1, and a reverse The open stirring cover 4, the stirring cover 4 is movably connected with the stirring paddle 2 through the fixed bolt 5, and a plurality of slurry inlets and outlets 41 are arranged symmetrically on the side wall.

Further, the width range of the slurry inlet and outlet 41 is 0.3-0.5cm, and the height range is 1.2-1.5cm, which can ensure the rapid entry and exit of the slurry; A certain gap is arranged, and its scope is 0.3-0.5cm, prevents the damage of paddle 21 to stirring cover 4; There is certain gap between the lower surface of stirring cover 4 and the bottom surface of container 1, and its range is 0.3-0.5cm, adjust The distance between the stirring cover 4 and the bottom of the slurry container 1 is sufficient, and there is no need to adjust the distance between the agitator and the bottom of the container.

In the present utility model, the height of the stirring cover 4 should be higher than the liquid level, and the height of the slurry inlet and outlet 41 should be lower than the liquid level.

The practice shows that the stirring device of the utility model can be used to prepare the slurry required by the button battery within 10-30 minutes, and its efficiency is greatly improved compared with the traditional stirring device.

The above-mentioned embodiments are preferred implementation modes of the present utility model, which are only used to facilitate the description of the present utility model, and are not intended to limit the present utility model in any form. Anyone with ordinary knowledge in the technical field, if they do not depart from this utility model Within the scope of the technical features mentioned in the utility model, the equivalent embodiments that make partial changes or modifications using the technical content disclosed in the utility model, and do not deviate from the technical features of the utility model, still belong to the technical features of the utility model within range.
