Mechanical fine screen is a good assistant for removing suspended substances, floating substances, sediments and other solid substances in paper making, slaughter, leather, sugar making, wine making, food processing, textile, printing and dyeing, and petrochemical industry wastewater treatment. Its greatest advantages are high automation, high separation efficiency, low power consumption, no noise, good corrosion resistance. It can ensure continuous and stable work without supervision. It can clean the pollution of all water-crossing sections and has high efficiency.

The grille beam of the mechanical fine screen is supported on the concrete foundation to make the cleaning machine run smoothly and work reliably; the tooth rake is inserted into the grille at a certain depth, and the dirt attached to the grille is brought to the top of the cleaning machine to complete the overturning and unloading action, so as to keep the water-passing section clean and free of dirt; the traction chain is generally made of stainless steel. Ensure that underwater work is free from rust and maintenance free.

In addition, overload safety protection devices are also installed in the mechanical fine screen, which will produce sound and light alarm and automatic shutdown when it breaks down, thus avoiding overload of equipment. In the mechanical grille, the grille is the main component, and it also has a great influence on the use effect of the equipment. The grille bar of the mechanical grille is composed of parallel flat steel, which is made of stainless steel and is tightened at the upper and lower ends. The spacing of the grille bar is 20 mm. The size of the grille frame corresponds to the width of the channel, and is fixed with stainless steel bolts and brackets. The grille bar is installed on the frame.

The screen frame is fixed on the concrete channel, and the gap between the frame and the channel wall uses flexible baffles to prevent wastewater from flowing through the grille. The flexible baffle is connected with the frame; the cross-section shape of each grid is rectangular. When the rake teeth mesh with the grid, the rake teeth have a certain angle with the vertical direction of the grid to prevent the accumulation of small dirt in the sewage; the guide rail on both sides of the grid can prevent the invasion of the grid slag and affect the work of the decontaminator.http://www.khnwatertreatment.com/
