[0002] Dispersing devices are usually used for mixing solids and liquids.

[0003] The dispersion device in the prior art usually includes a dispersion container, a serrated dispersion disk and corresponding moving parts. The moving parts drive the dispersion disk to rotate, so as to mix and disperse the materials in the dispersion container. However, the dispersion area of ​​the serrated dispersion disk is limited, which will cause the solid components in the solid-liquid mixture to be unevenly distributed, thereby affecting the quality of subsequent products; at the same time, its dispersion effect is poor, and it takes a long production time, resulting in low production efficiency.
