working principle

The rotary mechanical fine screen mainly consists of a frame, power unit, rake chain, cleaning mechanism, and electrical control box. The working principle is that the rake chain is a special shaped rake made of several stainless steel teeth, which are assembled in a certain order on the rake shaft to form a closed rake chain, and its lower part is installed in the water body of the inlet channel. When the transmission system drives the sprocket to rotate uniformly and directionally, the entire rake chain moves from top to bottom, carrying solid debris and separating it from the liquid. The liquid then flows through the gaps between the rake teeth. Due to the special structural shape of the rake, when the rake chain carries debris to the upper end and moves in reverse, relative self-cleaning motion occurs between the front and rear rake teeth, causing the debris to fall off by gravity. At the same time, a pair of rubber plates are set behind the equipment to ensure that each row of rake teeth can be brushed clean when they move to that position.

application

Rotary mechanical fine screen can be widely used in urban sewage treatment, water supply industry, power plant inlet, and can also be used as a front-end screening equipment in wastewater treatment processes in industries such as textile, food processing, papermaking, leather, etc. In addition, it is also suitable for sewage and rainwater pumping stations and sewage treatment plants, used to intercept and remove larger impurities, floating and suspended solids in sewage, and reduce the load of subsequent processes.

market conditions

In recent years, with the increasing emphasis on water resource protection and sewage treatment technology, the demand for rotary mechanical fine screens in the market has shown a steady growth trend. Manufacturers are constantly improving the design and technology of their equipment, enhancing its filtration efficiency, corrosion resistance, and automation level, while reducing costs. In addition, with the increasing demand for device interconnectivity and intelligent maintenance, there is also a growing demand for rotary mechanical fine screens that can provide remote monitoring and fault diagnosis capabilities.
