The Solid liquid separation machine can be effectively divided into small, medium and large in accordance with the amount of its treatment during the operation. The processing capacity of small solid-liquid separation equipment is generally within 1m3/H, such as three-legged centrifuge, scraper centrifuge, laboratory-specific centrifuge. Medium-sized spiral discharge sedimentation centrifuges, screw machines, stacking machines, filter presses, etc. The large ones are mainly centrifuges or filter presses with a large processing capacity, and the general processing capacity is 50-80m3/h. Since the centrifuge uses the centrifugal force generated by high-speed rotation to perform solid-liquid separation on a material with a large specific gravity, it is impossible to infinitely enlarge (the larger the centrifuge drum, the higher the manufacturing cost, and the lower the rotation speed), the largest drum at present. The diameter is about 1M.
Working principle of solid-liquid separation centrifuge
1. Fast mass transfer, short production cycle, easy operation and easy automatic control.
2. A series of advantages such as high separation efficiency and large production capacity, so the application is quite common.
3. It is a method of extracting some fluids or solid materials by using certain fluids with high diffusion coefficient and very low viscosity above their critical pressure and critical temperature, but having similar density to fluids. . It is characterized by high extraction capacity, high speed, and selectivity for certain substances by controlling operating pressure and temperature, and is beginning to be applied in bioengineering.
