Abstract: The invention relates to a cleaning apparatus (1) for removing solid matter from a liquid, especially for a coolant-lubricant circuit (35). Said cleaning apparatus (1) comprises a hollow cylindrical filter member (2) that separates a crude chamber (6) from a pure chamber (7), an inlet (8) which is located on the crude side and is connected to the crude chamber (6), an outlet (9) which is located on the pure side and is connected to the pure chamber (7), a backwashing device (10) for backwashing the filter member (2) segment by segment, and a discharge mechanism (12) for removing clean solid matter from the crude chamber (6). In order to make it easier to remove clean solid matter from the crude chamber (6), the filter member (2) surrounds the crude chamber (6) while the pure chamber (7) surrounds the filter member (2), and the discharge mechanism (12) is equipped with a screw conveyor (13) which feeds the clean solid matter to a discharge port (14).

Abstract: The aim of the invention is to improve the backwashing action of a backwashable filter for liquids comprising the following: a filter body which is located in a housing and which separates an incoming flow chamber from an outgoing flow chamber and a backwashing channel which lies adjacent to the filter body, is situated in the outgoing flow chamber and has a backwashing opening that faces towards the filter body, said backwashing channel also communicating with a source of a cleaning medium and said cleaning medium being subjected to pressure in the backwashing channel, and the filter body and the backwashing channel being moveable in relation to each other. To this end, the filter body has links on a side facing towards the backwashing channel which are set apart from each other in the direction of motion.
