The horizontal spiral discharge centrifuge is mainly composed of a high-speed rotating drum, a screw with the same direction as the rotating drum and a slightly higher or lower rotating speed than the rotating drum and a differential. When the suspension to be separated enters the centrifuge drum, the high-speed rotating drum generates a strong centrifugal force to settle solid phase particles with a density greater than the liquid phase to the inner wall of the drum. Due to the different rotation speeds of the spiral and the drum, the two exist There is relative motion (ie, difference in rotational speed), the relative motion of the screw and the drum is used to push the solid phase deposited on the inner wall of the drum to the outlet of the small end of the drum, and the separated clear liquid is discharged from the other end of the centrifuge. The role of the differential (gear box) is to form a certain speed difference between the drum and the screw.

Sludge and flocculant enter the horizontal spiral discharge centrifuge from the inlet of the mud pipe at the same time. In the centrifuge cavity, the flocculant produces a flocculation effect on the sludge in the mother liquor to generate solids heavier than water. Inside, the solid is thrown onto the drum wall, the separation liquid squeezes towards the center of the drum, the solid settled on the drum wall is pushed to the slag outlet by the screw conveyor, and discharged out of the machine, the separation liquid passes through the overflow hole of the big end of the drum Out of the machine. The differential is a device that guarantees the stability of the differential speed and produces a large torque. Coupled with the dual-motor dual-frequency conversion device that shares the DC bus, the drum speed and differential speed are infinitely adjustable, which can adapt to changes in flow and concentration. , To ensure a good and stable separation effect
