ABSTRACT:
An apparatus conveys screenings collected on a bar screen partially immersed in a sewage flow and inclined in the flow direction, and in certain cases on an adjoining apron screen. A rake device conducts the screenings to a discharge position at the upper edge of the bar screen or the apron screen. The screenings are conveyed simultaneously along at least two conveying paths and thus given screenings are transferred along mutually adjoining conveying paths. The rake device includes at least two rake members spaced at intervals in the conveying direction and connected together by a common drive that causes simultaneous translatory movements in the same direction of both rake members.
