Description

technical field [0001] The invention relates to the technical field of dispersing devices, in particular to a high-speed stirring and dispersing device. Background technique [0002] Various types of dispersers, mixers, and pulverizers are widely used in fine chemical and other chemical fields to disperse liquids and slurries. At present, with the rapid development of technologies in the fields of electronics, communications, and electric vehicles, it has also driven the rapid development of the lithium battery industry. In the early stage of lithium battery production, it involves the production of slurry for lithium batteries such as lithium cobalt oxide batteries and lithium iron phosphate batteries. The production of slurry must be carried out through dispersion equipment. The slurry dispersing equipment mainly includes a dispersing container, a discharge container, a dispersing shaft and a dispersing head, among which the dispersing head is a component that directly st...

Problems solved by technology

Therefore, the dispersion efficiency of the cylindrical dispersing head with the same upper and lower diameters is not high, and the internal pressure of the material in the lower part of the dispersing head is high, resulting in large resistance and serious heat generation.

In addition, the viscosity of some slurries will decrease during dispersing and stirring. If the distance between the outer cylindrical surface of the lower part of the dispersing head and the inner wall of the container is equal to the distance between the outer cylindrical surface of the upper part of the dispersing head and the inner wall of the container, the viscosity will decrease due to the decrease in viscosity. As a result, the internal pressure, resistance, and heat generation of the material in the lower part of the dispersing head are large, while the viscosity of the material in the upper part of the dispersing head is reduced, making the dispersion and mixing effect worse.
