Working principle and operation mode of water treatment decanter centrifuge

Jan 10, 2019

The drum of the water treatment decanter centrifuge is mounted on the upper end of the vertical shaft, and is driven by the motor to rotate at a high speed through the transmission; the drum has a set of disc-shaped parts that are nested on each other - the disc, between the disc and the disc A small gap is left; the suspension is added to the drum by a feed tube located at the center of the drum. When the suspension passes through the gap between the discs, the solid particles settle to the disc under the action of the centrifuge to form a sediment.

 

The sediment slides along the surface of the disc to separate from the disc and accumulates in the portion of the drum having the largest diameter, 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, enlarge the settlement area of the drum, and greatly improve the production capacity of the separator due to the installation of the disc in the drum. 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.

 

It can be seen that the water treatment decanter centrifuge can perform two operations, namely a clarification operation of liquid-solid separation and a separation operation of liquid-liquid separation. Moreover, the water treatment decanter centrifuge is widely used in chemical, pharmaceutical, light industry, food, bioengineering and transportation sectors due to its compact structure, small footprint and large production capacity.
