AI Technical Summary
Technical Problem
Existing ceramic membrane equipment does not perform thorough solid-liquid separation in fermentation broth, resulting in a low solid-liquid separation rate.
Method used
The porous structure membrane sintered at high temperature is combined with cross-flow filtration technology to achieve high-speed flow of materials on the membrane surface, small molecules pass through the membrane, large molecules and impurities circulate back, and a booster pump is used for pressurization treatment.
Benefits of technology
The clear and transparent filtrate separation is achieved, and the incomplete separation is avoided. The recycled reflux material can be filtered again, which improves the separation efficiency.

Abstract
The utility model discloses ceramic membrane equipment for solid-liquid separation of fermentation liquor, and particularly relates to the field of ceramic membrane equipment, the ceramic membrane equipment comprises a mounting rack, rollers are mounted at the bottom end of the mounting rack, and a tank body is fixedly mounted in the mounting rack. According to the utility model, the diaphragm is a precise ceramic filter material which is formed by sintering at a high temperature and has a porous structure, and ceramic membrane filtration is a fluid separation process in a cross-flow filtration form: under the driving of pressure, the material flows at a high speed on the surface of the diaphragm layer at a certain flow speed; the small molecular substances penetrate through the membrane layer along the direction vertical to the small molecular substances and then enter the permeate tank; and insoluble thalli, macromolecular impure proteins, suspended solids, colloids, small particles and the like are intercepted by the membrane and circularly flow back into the raw material tank, so that the purpose of solid-liquid separation of the materials is realized, the obtained filtrate is clear, transparent and sterile, the materials circularly flow back into the raw material tank can be circularly filtered, and the condition of incomplete separation is effectively avoided.
