Two Phase Stainless Steel Scroll Decanter Centrifuge For Centrifugal Dewatering

Two Phase Stainless Steel Scroll Decanter Centrifuge For Centrifugal Dewatering

1.Introduction   

The horizontal spiral discharge sedimentation centrifuge is a mechanical equipment that uses the principle of centrifugal sedimentation to continuously separate the materials containing density difference in the suspension.

Juneng was engaged in solid-liquid separation in 1983, among which the horizontal spiral centrifuges were widely used in various industries: kitchen waste, gutter oil, aerobic excess sludge dewatering, anaerobic excess sludge dewatering, plant extract clarification, cyanobacteria treatment, sludge dewatering, medical fermentation liquid treatment, PVC dewatering, kaolin grading, starch concentration, petroleum and petrochemical, mining, construction and other industries, ensuring the quality of Juneng machinery.

2.Basic principle

The basic principle is as follows: the drum and the feeding screw rotate at a high speed at a certain differential speed. The materials are continuously introduced into the inner spiral pushing cylinder from the feeding pipe, and then enter the drum after acceleration. Under the action of centrifugal force field, the heavier solid particles are deposited on the drum wall to form a sediment layer. The material conveying screw pusher continuously pushes the deposited solid substances to the cone end of the drum, and after dehydration in the drying area, the solid substances are discharged out of the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, and the overflow port at the big end of the drum continuously overflows the drum, and the solid substances are discharged out of the machine through the liquid outlet port. Under full speed operation, the machine can continuously complete feeding, settling, separation, dehydration, unloading and other processes.

3.Product structure 

The centrifuge is a countercurrent horizontal spiral discharge sedimentation centrifuge for sludge dewatering. The main engine is composed of drum (stainless steel 2205), screw (stainless steel 2205+316L) and differential system. The differential speed is automatically fed back and adjusted according to the load change, and the pushing power is automatically compensated to ensure the constant dryness of the solid slag and get a drier solid slag.

It is poured by an integral centrifuge, and then processed by precision turning after solution treatment. The solid phase slag discharge port is equipped with replaceable tungsten carbide wear-resistant bushing. The inner wall of the centrifuge drum is welded with anti-skid wear-resistant strips to prevent the solid particles from tangential rotation and wear on the inner wall of the drum.
