Abstract

In the cleansing especially of cooling water for a heat exchanger the installation of rotationally symmetric filter bodies in the cooling water feeder pipe and suction of sediments across a suction nozzle rotating on the windward side. Difficulties result therein in the production of a required back-flow through the filter and the avoidance of lateral airfluxes in front of the filter surface, as a certain gap is necessary between filter and suction nozzle for holding the sediments. In order to guarantee problem-free suction it is provided according to the invention that the windward filter surface (2) is subdivided into individual sectors (14) by radial ridges (13) projecting against the direction of flow, whose central angle corresponds maximally to that of the nozzle (6) of the suction device also in the shape of a sector and that the gap between the free ridge edges (13) and the edges of the nozzle (6) circulating at a distance from the ridge edges is bridged by flexible sealing lips of at least the width of the gap.
