Description

technical field [0001] The invention belongs to the technical field of high-shear crushing and homogenizing equipment, and relates to a stator-rotor structure of high-shear equipment, in particular to a stator-rotor structure with a replaceable crushing ring gear. Background technique [0002] In the food and pharmaceutical industry and petrochemical industry, high-shear equipment is a new type of equipment used for crushing, homogenization, emulsification, dispersion and mixing. Its main principle is to use the relative shearing effect between the crushing rack on the stator and the rotor to reduce the size of the larger particle material, or / and realize the uniform mixing of different phase materials. In the prior art, the stator and rotor of the high-shear equipment are processed by integral wire cutting or milling, and the number of teeth of each ring gear and the opening clearance of the rack are the same, which results in a larger diameter The material utilization rat...

Problems solved by technology

In the prior art, the stator and rotor of the high-shear equipment are processed by integral wire cutting or milling, and the number of teeth of each ring gear and the opening clearance of the rack are the same, which results in a larger diameter The material utilization rate of the large outer ring gear is very low, and it is impossible to form the crushing effect that the inner ring is coarsely crushed first, and then the outer ring is finely crushed; in addition, the stator and rotor are vulnerable parts, once a certain rack or ring gear If it is worn out, the entire stator or rotor needs to be replaced, which leads to a waste of maintenance costs; moreover, for the integral stator and rotor, the number of teeth of the ring gear and the clearance of the rack cannot be adjusted. In order to achieve different To achieve the best crushing effect and adapt to different crushing requirements, different stators and rotors need to be replaced, and the cost of use is also high

[0003] In addition, a stator-rotor structure is also described in a patent document titled "A Stator-Rotor Structure of a Detachable High-shear Grinding Equipment" filed by the inventor earlier, and the publication number is "CN101873015A". The crushing rack is installed as a single piece, but this type of installation makes the size of the stator and rotor larger, which brings more energy consumption, and the ratio of tooth thickness to inter-tooth gap (length-to-diameter ratio) is relatively large. The problem of poor material flow caused by
