Mechanical grille ‖ Features and working principle
As a sewage pretreatment equipment, the screen decontamination machine is widely used and has a wide range of applications. It can meet the needs of various sewage pretreatments. It has high filtering accuracy for large suspended solids and can effectively achieve solid-liquid separation.
Main features of the screen decontamination machine:
The screen decontamination machine has a compact structure, simple electrical control, and a high degree of automation; excellent corrosion resistance, low energy consumption, and low noise; continuous decontamination action, clean sewage discharge, and high separation efficiency.
Working principle of the screen decontamination machine:
The screen decontamination machine can choose special-shaped rake teeth made of ABS engineering plastics, nylon or stainless steel, which are installed on the rake tooth shaft in a certain arrangement order to form a closed rake tooth chain, and its lower part is installed in the water of the water inlet channel. When the transmission system drives the sprocket to rotate at a uniform speed, the entire rake tooth chain moves from top to bottom, and carries solid debris to separate from the liquid, and the fluid flows out through the rake tooth gap, and the entire working state is continuous.
Due to the special structural shape of the rake teeth, when the rake chain carries debris to the upper end and moves in the opposite direction, a relative self-cleaning movement occurs between the front and rear rakes, causing the debris to fall off by gravity. A rotating cleaning brush can be set behind the equipment to further remove the dirt trapped on the rake teeth.
The equipment is a non-standard product and can be customized according to user needs to ensure that the equipment can meet the actual needs of users and improve work efficiency.
