In the operation of the high-speed decanter centrifuge, the drum is mounted on the upper end of the vertical shaft, and can be driven by the motor to rotate to a certain extent to a certain extent. At a certain extent, the drum has a set of discs that are nested together. Parts - discs. There is a small gap between the disc and the disc. The suspension (or emulsion) is added to the drum by a feed tube located in the center of the drum. When the suspension (or emulsion) passes through the gap between the discs, the solid particles (or droplets) settle to the disc under the action of a centrifuge to form a sediment (or liquid layer).
The sediment of the high-speed decanter centrifuge slides along the surface of the disc to separate from the disc and accumulates in the portion with the largest diameter inside the drum, and the separated liquid is discharged from the liquid outlet to the drum. The function of the disc is to shorten the settlement distance of the solid particles (or droplets) and enlarge the settlement area of the drum. The drum has greatly improved the productivity of the separator due to the installation of the disc. The solids accumulated in the drum are dismantled by the drum after the machine is shut down, or are discharged from the drum by the slag discharge machine without stopping the machine.
High-speed decanter centrifuges can generally perform two operations, liquid-solid separation (ie separation of low concentration suspension), called clarification operation, liquid-liquid (or liquid-liquid-solid) separation (ie emulsion) Separation), called the separation operation. With its compact structure, small footprint and large production capacity, the disc separator has been widely used in chemical, pharmaceutical, light industry, food, bioengineering and transportation sectors.
