Self Cleaning Horizontal Decanter Centrifuge China Especially For Desulfurization Sludge

1. Overview

Desulfurization sludge centrifuge is a horizontal spiral discharge and continuous operation sedimentation equipment.

The working principle of this type of separator is: the drum and the screw rotate at a certain differential speed in the same direction and high speed, and the material is continuously introduced into the inner cylinder of the feeding screw through the feed pipe, and then enters the drum after acceleration. Under the action of the centrifugal force field, the heavier solid matter is deposited on the drum wall to form a sediment layer. The conveying screw continuously pushes the deposited solids to the cone end of the drum and discharges them out of the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, which continuously overflows the drum from the overflow port at the large end of the drum and is discharged out of the machine through the drain port.

This machine can continuously feed, separate, wash and discharge materials at full speed. It is characterized by compact structure, continuous operation, stable operation, strong adaptability, large production capacity and convenient maintenance. It is suitable for separating suspensions with particle size greater than 0.005mm and concentration range of 2-40%. It is widely used in chemical, light industry, pharmaceutical, food, environmental protection and other industries.

2. Working principle

The sludge enters the desulfurized sludge centrifuge from the feed pipe. Under the high-speed rotation of the drum, the heavier solids are thrown to the drum wall, and the lighter liquids are squeezed to the center of the drum. Under the differential speed of the screw and the drum, the solids settled on the drum wall are pushed by the screw conveyor to the slag outlet at the small end of the drum and discharged out of the machine. The liquid is discharged out of the machine through the overflow hole at the large end of the drum.

3. Model selection

Selecting a suitable desulfurized sludge centrifuge can not only solve the problem of sludge desulfurization and separation, improve work efficiency, but also save production costs and reduce business risks. The main factors affecting model selection are as follows:
