Chain screen
The cleaning elements, attached to the chain system, can easily be adjusted to different requirements. These elements can be conventional rakes, or brushes, or plastic wipers. As the cleaning elements are changeable, the screenings discharge capacity is then adjustable. This is especially favourable for high solids loads. The cleaning elements, consisting of the rake and comb plate, are screwed and thus independently replaceable.
Function:
The main components of the Chain Screen are two drive chains with one or more cleaning elements, chain wheels on the drive shaft and the lower deflection unit, a guiding on each side, a drive unit with overload protection, an apron with chute and a bar screen. The complete unit can be installed in the civil structure without need of recesses, thus reducing the costs for new buildings and allowing easy retrofitting into existing civil structures.
