Abstract

The invention belongs to the field of chemical equipment, and relates to a rotor-stator assembly for dispersing or sand milling. The outer circle face of a rotor and the inner circle face of a stator are both provided with a bulge in the shape of zigzag, gear or ripple. The circumference and the area of the outer circle face of the rotor and the circumference and the area of the inner circle face of the stator are larger than the circumference and the area of rotors and stators in conventional dispensers, emulsifying machines or grinders. No mechanical contact force are applied for refining and mixing according to the rotor and the stator of the assembly, and the surface of a sensitive material has little damage, so that the rotor-stator assembly is applicable to materials with sensitive surface structure. Countless surge currents are formed on the bulge at the inner circle face of the stator, and an initially-dispersed material is again subjected to compression and impaction by powerful kinetic energy of the rotor, so that the special effect of cutting plus disperse helps to obtain a uniform ultrafine mixed material based on a microscopic concept in the shortest time.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and relates to a rotor and stator assembly used for dispersion or sand milling, in particular to a rotor and stator assembly in a disperser, emulsifier or grinder. Background technique [0002] In the production process of various industries such as petrochemical industry, food, biopharmaceutical, electrochemical industry, textile printing and dyeing, pesticide and chemical fertilizer, new energy, etc., the process of mixing, homogenization, dispersion and emulsification is inseparable, especially the nano-scale new Materials are constantly emerging. Nanomaterials and fine materials have large specific surface areas and are easy to agglomerate. Many electrochemical micromaterials are very sensitive in structure. It is not easy to disperse evenly by using traditional dispersion stirring or cone milling. Using cone milling, some tiny Sensitive materials are easily worn or damaged during the stirri...
