Abstract

The invention relates to the technical field of material dispersion, in particular to a solid-liquid dispersion device which can realize uniform dispersion of slurry, improve dispersion effect and reduce preparation time.

Description

Solid-liquid dispersion device

Technical Field

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

Background

In the production process of lithium battery slurry, need disperse it, traditional dispersion devices all are that a large amount of powder and liquid get into from the container upper end, then high-speed dispersion impeller disperses the mixture to the material, and the thick liquids after the mixture are followed the bottom ejection of compact, and the material mixing degree that above-mentioned dispersion was come out is not very high, and dispersion effect is relatively poor, and dispersion time is longer moreover, and product preparation is inefficient.

Disclosure of Invention

In order to solve the problems of low uniformity degree of slurry, poor dispersion effect and long slurry preparation time after the existing dispersion, the invention provides a solid-liquid dispersion device which can realize uniform dispersion of the slurry, improve the dispersion effect and reduce the preparation time.

The technical scheme is as follows: the solid-liquid dispersing device comprises a rotor and a stator and is characterized in that the rotor is a conical impeller, blades are mounted on the conical impeller, notches are formed in the blades, a fixed annular stator is arranged in each notch, through holes are formed in the peripheral surface of the annular stator, and gaps are reserved between the annular stator and the blades.

The impeller is further characterized in that the conical impeller comprises a bottom circular plate and a conical surface part arranged on the circular plate, the blades extend to the circular plate from the conical surface part, the notch is formed in the circular plate, and an annular groove corresponding to the notch is formed in the circular plate;

the clearance between the annular stator and the blades is 0.5-5 mm.

After the invention is adopted, powder and liquid are pre-mixed and conveyed to the matching surface of the stator and the rotor under the action of the axial and radial conveying capacity of the rotor, the blades are matched with the annular stator, strong shearing and dispersion are realized on the inner surface of the annular stator, and uniformly dispersed slurry is prepared from the through holes, so that the dispersion effect is improved, and the preparation time is reduced; furthermore, besides continuous production, a transfer tank can be arranged for slurry difficult to disperse for circulating dispersion, the dispersion effect and efficiency are further improved, and the preparation time of the product is saved.

Detailed Description

As shown in fig. 1, the solid-liquid dispersing device comprises an annular rotor 1 and a stator 2, wherein the rotor 1 is a conical impeller, blades 3 are arranged on the conical impeller, a notch 7 is formed in each blade 3, the annular stator 1 fixed on a shell 9 is arranged in each notch, a through hole is formed in the outer peripheral surface of each annular stator 1, and a gap 4 is reserved between each annular stator 1 and each blade.

The clearance between the annular stator 1 and the blades 3 is 0.5-5 mm.

The through holes can be changed as required, as shown in fig. 2, 3 and 4, the through holes are respectively small round holes, square holes and kidney-shaped holes, a gap 4 is reserved between the annular stator 1 and the blade 3, and the dispersion effect is related to the shape and the size of the through holes.

The conical impeller comprises a bottom circular plate 5 and a conical surface part 6 mounted on the circular plate 5, the blades 3 extend to the circular plate 5 from the conical surface part 6, the notches 7 are formed in the circular plate 5, annular grooves 8 corresponding to the notches 7 are formed in the circular plate 5, the conical impeller 6 rotates to drive the blades 3 to rotate, and intensive shearing and dispersion are achieved between the blades and the inner and outer surfaces of the annular stator 1.

The blade 3 may be flat or curved, as shown in fig. 5 and 6.

Fig. 7 gives a schematic view of the shearing principle.
