Abstract
An apparatus for the mechanical cleaning of liquids, especially cooling water delivered from a heat exchanger and flowing in a pipeline (10), with a rotationally symmetrical, conical sieve (12) of substantially the size of the pipe diameter, as well as a coaxial suction device (20) which is disposed on the upstream side of the sieve, is mounted for rotation continuously or with interruptions for the duration of a cleaning interval, and during the cleaning interval sucks bit by bit the entire surface of the sieve (12) on the upstream side, the sieve (12) being divided into areas, the intake nozzle (22) of the suction device (20) can cover each area, and in each area of the actual sieve surface and of the suction device there is a cavity for the temporary accommodation of contaminants, the sieve (12) being divided on its upstream side by substantially radial barriers (36) into individual sectors forming the areas, the intake nozzle (22) of the suction device (20) has such a shape that, at the moment in which the intake nozzle just covers one sector, and leaves adjacent sectors substantially free, the gap between the free barrier edges and the edges of the intake nozzle (22) of the su…
