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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
