Production process and composition requirements of Three-phase separation centrifuge

Mar 28, 2019

The working principle of the Three-phase separation centrifuge is that after two liquid phases and one solid phase enter the centrifuge, the centrifugal force field is mainly expanded by several thousand times during operation, and the solid phase is settled under the action of centrifugal force. During the operation, the two liquid phases also appear stratified, thereby realizing the solid-liquid-liquid three-phase separation and discharging the body separately under the action of a special mechanism. The entire feed and separation process is continuous, closed, and automated.


The three-phase separation centrifuge is mainly composed of drums, spirals, differentials, frames, casings, motors and other components. The drum adopts a double-vertebral angle design, and the inner wall of the drum is specially designed with a longitudinal concave-convex groove for improving the efficiency of the spiral conveying solid phase. The working surface of the spiral blade has a hard alloy protective layer, which effectively improves the wear life of the spiral blade.


The main motor of the three-phase separation centrifuge is mainly controlled by the inverter during the production, and the sub-motor is controlled by the sub-inverter, and the frequency of the motor can be arbitrarily adjusted. The power supply of the auxiliary frequency converter is provided by the main frequency converter, which is called DC common bus power supply. The DC common bus power supply realizes the energy feedback when the auxiliary motor is in the working state of the generator, which can effectively save energy.
