Description

A horizontal multi-stage solid-liquid dispersion device

technical field

The invention relates to the technical field of material dispersion, in particular to a horizontal multi-stage solid-liquid dispersion device.

Background technique

In the production process of lithium battery slurry, it needs to be dispersed. The traditional dispersion device is that powder and liquid enter from the upper end of the container, and then the dispersion module disperses and mixes the materials, and the mixed slurry is discharged from the bottom. The mixing degree of the above dispersed materials is not very high, and the dispersion effect is poor.

SUMMARY OF THE INVENTION

In order to solve the problems of low uniformity and poor dispersion effect of the existing slurry after dispersion, the present invention provides a horizontal multi-stage solid-liquid dispersion device, which can realize uniform dispersion of the slurry and improve the dispersion effect.

Its technical scheme is as follows: a horizontal multi-stage solid-liquid dispersion device includes a dispersion shell, characterized in that a horizontal dispersion shaft is installed in the dispersion shell, and the dispersion shaft is sequentially provided with a first dispersion shaft. A dispersion module and a second dispersion module, the end of the dispersion shell at one end of the first dispersion module is provided with a liquid inlet, and the side wall of the dispersion housing at the second dispersion module is provided with a slurry outlet, The side wall of the dispersion housing between the liquid inlet and the slurry outlet is provided with a solid inlet, and the slurry outlet communicates with the liquid inlet through a pipeline and a pump.

It is further characterized in that the first dispersion module includes a rotor connected to the dispersion shaft, the rotor is an inner impeller or an inner movable ring, the inner movable ring is provided with a first dispersion hole, and the inner wall of the dispersion shell is formed. A stator is fixed on it, the stator is an outer fixing ring, and the peripheral surface of the outer fixing ring is provided with a second dispersion hole;

The first dispersing module is a movable toothed ring, and the inner wall of the dispersing housing is provided with a fixed toothed ring matched with the movable toothed ring;

The second dispersion module is a conical impeller;

There are two to ten first dispersing modules.

After adopting the present invention, powder and liquid enter from the side wall and end of the dispersing shell respectively, pass through the first dispersing module and the second dispersing module for multi-stage dispersing and mixing, go out from the slurry outlet, and enter through the liquid inlet for circulating dispersion, The uniform dispersion of the slurry is realized, and the dispersion effect is improved.

Detailed ways

As shown in Figure 1, a horizontal multi-stage solid-liquid dispersion device includes a dispersion shell 1, a horizontal dispersion shaft 2 is installed in the dispersion shell 1, and the dispersion shaft 2 is sequentially provided with a first dispersion module 3, In the second dispersing module 4, a liquid inlet 5 is opened at the end of the dispersing shell 1 at one end of the first dispersing module 3, and a slurry outlet 6 is opened on the side wall of the dispersing shell 1 at the second dispersing module 4. The liquid inlet 5 and The side wall of the dispersion shell 1 between the slurry outlets 6 is provided with a solid inlet 7, and the slurry outlet 5 and the liquid inlet 6 are communicated with the liquid inlet 6 through pipelines and pumps, which can realize circulating dispersion, can prepare uniform slurry and can greatly shorten the time. Slurry preparation time.

The first dispersion module 3 includes a rotor connected to the dispersion shaft 2. The rotor is an inner impeller or an inner movable ring. The inner movable ring is provided with a first dispersion hole. The inner wall of the dispersion housing 1 is fixed with a stator. The peripheral surface of the fixed ring is provided with a second dispersing hole, the first dispersing module can also be a movable toothed ring, and the inner wall of the dispersing housing 1 is installed with a fixed toothed ring that cooperates with the movable toothed ring, as shown in Figure 2, except for the fixed toothed ring A and the movable ring gear a must be used together. The rest of the stators B, C, and D can be used in conjunction with the rotors b, c, and d. In order to achieve the best dispersion effect, B-b, C-c, and D-d are required.

As shown in FIG. 3 , the second dispersing module 4 is a conical impeller.

There are two to ten first dispersing modules 3, which can better realize the multi-level dispersing effect.
