Full-speed operation and centrifugal force of horizontal spiral centrifuge

Jun 20, 2020

In the process of working, the horizontal screw centrifuge mainly rotates the drum and the screw at the same direction and high speed at a certain differential speed. The material is directly introduced into the feeding screw inner cylinder through the feed pipe, and enters the drum effectively after acceleration. Under the action of centrifugal force field, heavier solid phase deposits 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 large end overflow port of the drum and is discharged out of the machine through the liquid discharge port.

Horizontal spiral centrifuge can continuously feed, separate, wash and unload at full speed. 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 horizontal spiral centrifuge should be above 3000 rpm. The higher the rotation speed, the higher the centrifuge separation factor and the better the separation effect. Different materials have different physical and chemical indicators such as wear resistance and corrosion resistance. Differential control of centrifuges: different differentials have different control accuracy, and the life and maintenance costs are very different. The higher the differential accuracy, the greater The better the adaptability, it is better to choose equipment with high differential accuracy.

The greater the length-diameter ratio of the decanter centrifuge, the greater its processing capacity and the smaller the moisture content. Control system: Whether it is automatic programming control, domestic and foreign equipment manufacturers have basically realized the fully automatic control of the equipment. Installed power: affects the control of energy consumption, the general domestic equipment energy consumption ratio is high, and the foreign energy consumption ratio is low.

The decanter centrifuge belongs to the separation equipment required for high-precision processing. The products produced by enterprises that do not have precision processing capabilities have a high maintenance rate and limited processing capacity. Install according to the design layout of the heating furnace or the installation diagram of the heat exchanger.
