In industrial production, horizontal spiral centrifuges are basically aftertreatment equipment, mainly used for dehydration, concentration, separation, clarification, purification, and solid particle classification processes. They have been developed with the development of various industrial departments. For example, after the industrial revolution in the 18th century, with the rapid development of the textile industry, cotton cloth dehydrators appeared in 1836. In 1877, a separator for separating milk was invented to meet the needs of the cheese processing industry.
After entering the 20th century, with the development of comprehensive utilization of petroleum, it was required to remove water, solid impurities, tar like materials, etc., in order to use heavy oil as fuel oil. In the 1950s, a disc piston slag extractor with automatic slag removal was successfully developed, and by the 1960s, it became a complete series of products. With the development of modern environmental protection and "three wastes" treatment, there are high requirements for industrial wastewater and sludge dewatering treatment, especially the development of horizontal spiral discharge sedimentation centrifuges is particularly rapid.
It can be seen that the structural optimization of horizontal spiral centrifuges can effectively improve the working performance and bring good economic benefits. However, most people conduct separate research on components such as screw conveyor and drum, while few have conducted overall research on screw drum group.
With the development of modern industrial civilization and human attention to the environment and sustainable development strategy, good separation effect, low vibration, and low noise have become important conditions for the product to be accepted by the market. Generally, dynamic characteristics include critical speed, unbalanced response, and stability. The selection and optimization of its parameters is the first step to improve the dynamic characteristics of a centrifuge.
