Product Details
Description
• The rotary drum fine screen bar screen uses a circular screening drum as the screen surface.
• which is installed in the water channel at an angle of 35° to the horizontal plane.
• Sewage flows into the screening drum from the end of the screen. Suspended solids, floating objects, etc.
• larger than the screen gap are intercepted on the inner surface of the screening drum.
• Driven by a motor to rotate, the slag - cleaning brush and flushing device above the screening drum clean the screen surface, flushing the filter residue into the central slag trough.
• It is then lifted by a conveying screw, squeezed and dewatered until it reaches the upper discharge hopper and is transported away by a conveyor.
Advantage
• The range of screen bar gaps is wide, from 0.5 to 12mm.
• Forming a 35° angle with the water flow, the resulting baffling flow can greatly improve the separation of fine dirt.
• The self - contained flushing device automatically cleans during operation, reducing blockages and having a low maintenance cost.
• Compared with traditional screens, it has a large water - passing flow rate, less head loss, and a smaller accumulation plane in front of the screen.
• High dirt - interception efficiency, closed - type conveying, causing no environmental pollution.
• The equipment can be fully automatically controlled, with smooth operation, low energy consumption, and low noise.
• Integrated design of retrieving, conveying, and pressing treatment, with a compact structure and small footprint.
