Background

The horizontal screw centrifuge is called horizontal screw settling centrifuge, which is a high-efficiency centrifugal separation device. The working principle of the centrifuge is as follows: the rotary drum and the screw rotate at a high speed in the same direction at a certain differential speed, materials are continuously introduced into the conveying screw inner cylinder through the feeding pipe, enter the rotary drum after being accelerated, and heavy solid-phase substances are deposited on the wall of the rotary drum to form a slag layer under the action of a centrifugal force field. The conveying screw continuously pushes the deposited solid-phase substances to the conical end of the rotary drum and discharges the solid-phase substances out of the machine through the slag discharge port. The lighter liquid phase forms an inner layer liquid ring, continuously overflows from the rotary drum through an overflow port at the large end of the rotary drum, and is discharged out of the machine through a liquid discharge port. The machine can continuously feed, separate, wash and discharge materials under full-speed operation. Has the characteristics of compact structure, continuous operation, stable operation, strong adaptability, large production capacity, convenient maintenance and the like. It can be widely used in chemical industry, light industry, pharmaceutical food industry, and environmental protection industry.

In the purification of fish oil, the decanter centrifuge plays very important role, and the decanter centrifuge can separate solid fish residue, fish oil and aqueous phase fish soluble paste, and after the decanter centrifuge operation was ended, there can be a lot of greasy dirt and residue in centrifuge inside, need rinse inside, therefore the decanter centrifuge all can be furnished with the cover and have belt cleaning device.
