Working principle of decanter centrifuge
Horizontal spiral sedimentation centrifuge is simply referred to as horizontal spiral centrifuge, which is an efficient centrifugal separation equipment. Horizontal spiral centrifuges can generally be divided into horizontal spiral filter centrifuges and horizontal spiral sedimentation centrifuges. The decanter centrifuge is a horizontal spiral unloading, continuous operation settling equipment.
Working principle of horizontal spiral sedimentation centrifuge:
The working principle of the centrifuge is: the drum and the spiral rotate at the same direction and high speed at a certain differential speed, the material is continuously introduced into the inner cylinder of the feeding spiral through the feed pipe, and enters the drum after acceleration, under the action of the centrifugal force field, the heavier solid phase Deposited on the drum wall to form a sediment layer. The conveying screw continuously pushes the deposited solid phase to the cone end of the drum and discharges it out of the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, which overflows the drum continuously from the overflow port of the large end of the drum and is discharged out of the machine through the liquid discharge port. The machine can continuously feed, separate, wash and unload under full-speed operation. It has the characteristics of compact structure, continuous operation, stable operation, strong adaptability, large production capacity and convenient maintenance. It is suitable for separating suspensions containing solid phases with a particle size greater than 0.005mm and a concentration range of 2-40%. Widely used in chemical, light industry, pharmaceutical, food, environmental protection and other industries.
The application of decanter centrifuge in environmental protection mainly refers to the dewatering of sludge generated in the process of industrial and civil sewage treatment. Todays environmental issues have become the focus of common concern all over the world. Under this background, the value of the decanter centrifuge is reflected. In the past, sewage plants or related treatment plants used self-settlement or belt filter presses to dewater and concentrate sludge. The test proves that the sludge moisture content is reduced from 98% to 80%, and its volume can be reduced by 10 times. Because of this, the decanter decanter centrifuge has the characteristics of large processing capacity, automatic operation, and good dehydration effect. The protection field has been widely used and promoted by 7a64e58685e5aeb931333365663463. The single product sales of decanter centrifuges account for about half of all centrifuge products, laying its irreplaceable position. In foreign countries, decanter centrifuges are preferred for sewage treatment equipment.
