The screen surface, formed of wear-resistant plastic plates and circulating on chains, flows through the channel from the front. An optimal take-out of the sieved solids is provided due to the screen surface’s rake form. These are discarded at the upper deflection point of the screen. An extensive mechanical cleaning, supplemented by an additional rotating brush, occurs due to the meshing of the screen elements at the deflection points.
Two screen surfaces are created by using similar rake-shaped screen elements, which are closely connected forming an endless filter belt. The first screen surface consists of the forearms of the screen elements and holds back the larger solids. The second screen surface consists of the rear arms of the same screen elements and holds back the finer solids. The solids lie loosely on both screen surfaces. Thus they present the flowing liquid with only low resistance and are lightly discarded at the discharge side.
The sieve can be used directly in an open flow channel. In this way pumping can be omitted.
• Side plates made of stainless steel or normal steel
• Screen slot from 1 mm
• lso for large amounts of waste water
• Installation in the duct, no pumping required
• Self-cleaning screen surface
