In the soda ash industry, it is theoretically feasible to use centrifuge for secondary dehydration of heavy alkali to reduce energy consumption. The three-stage piston pushing centrifuge is adopted. The working process is that the screw feeder will continuously input the material containing a certain proportion of water into the distributor, and the distributor will evenly distribute the material on the first-level sieve basket surface. At this time, most of the liquid of the material is separated and the filter cake sieve basket is constantly rotating, and the pushing system does reciprocating movement under the action of liquid pressure; It's also spinning at full speed. When the pusher system pushes forward, the pusher plate installed on the primary pusher ring pushes the filter cake on the primary sieve basket surface to the secondary sieve basket;

The daily maintenance of centrifuges is mainly to prevent contamination in the centrifugal chamber, falling into dust and being contaminated with oil. Before and after each experiment, clean the oil, water vapor, sample leakage and table surface in the centrifugal chamber with a clean white silk cloth. Do not open the door when not in use, so as not to pollute. The sealing rubber ring of the machine door should be sealed well, and vacuum sealing grease should be applied after a period of use. If the seal ring is found to be aging, cracking and losing elasticity, it should be replaced immediately. The switch, knob and fault indicator on the control panel should ensure good contact, and the abnormal and fault should be stopped immediately for maintenance.
