The composition, use and characteristics of the three-phase decanter centrifuge May 29, 2018

A three-phase decanter centrifuge is a mechanical device that uses the effect of centrifugal force to separate solids from liquids and liquids. After the suspension is fed from the feed pipe into the drum, with the high-speed operation of the three-phase decanter centrifuge, the solid particles are accelerated by the centrifugal force to the inner wall of the drum under the action of the centrifugal force field and are driven from The settling area is discharged through the drying zone to the solid phase outlet.

 

At the same time, the treated liquid phase will also overflow from the overflow hole, so that the three-phase decanter centrifuge realizes the automatic and continuous separation of solid and liquid phases. Can be applied to dehydration, concentration, clarification and other different occasions. The equipment is mainly composed of drums, screws, differentials, frames, housings, motors and other components.

 

The main purpose of the three-phase decanter centrifuge: The equipment has a wide range of applications, involving different industrial areas, such as its use for industrial and domestic sewage separation and dehydration, including starch washing, grading, dewatering and so on. In addition, separation and purification of vegetable oil, separation and purification of coal tar, classification and dehydration of dyes and pigments can also be achieved.

 

The main features of the three-phase decanter centrifuge are as follows: 1. The key parts of the equipment, such as the drum and screw, are made of corrosion-resistant stainless steel to ensure its service life; 2. The spiral conveyor sprays wear-resistant alloy or inserts. Welded carbide sheet (optional); 3, drum speed stepless speed regulation; 4, screw differential speed adjustable (step or stepless speed regulation); 5, safety protection, including speed detection.

 

In fact, the separation process of a three-phase decanter centrifuge is mainly performed under the action of centrifugal force. It depends on the centrifugal force field to expand several thousand times. The solid phase is settled under the action of centrifugal force, and the two liquid phases are also stratified. In order to achieve solid-liquid-liquid three-phase separation, and the body under the action of the special body. Under normal circumstances, the entire feeding and separating process of the three-phase decanter centrifuge is continuous, closed, and automatic.
