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.
Device for the mechanical cleansing of fluids in a cooling water feeding pipe, comprising a rotationally symmetric filter body disposed in and extending over the entire cross section of a cooling water feeding pipe, said filter body having upstream and downstream filter surfaces as seen in a given flow direction through the cooling water feeding pipe, radial ridges projecting from said upstream surface against said given flow direction forming chambers with said upstream surface and sub-dividing said upstream surface into individual sectors each having a given central angle and a two-dimensionally domed shape, said radial ridges having free edges, a rotatable suction device coaxial with said filter body, means for rotating said suction device for partially acting upon and completely successively sweeping said upstream filter surface, said suction device having a sector-shaped nozzle with a central angle substantially equal to said given central angle, said nozzle having edges circulating at a distance from said free edges of said radial ridges defining a gap therebetween, and flexible sealing lips attached to said free edges of said radial ridges and being at least as wide as said gap and bridging said gap.
