A screening apparatus for solids in a power plant condenser water line has a head orbiting the filter element which spans the outlet end of the pipe section forming the housing for the unit and flanged in this pipeline. A motor is mounted on the pipe section and is connected by a right-angle drive to cause orbiting of the head and the suction pipe is connected by an elbow to the axial hollow shaft of the head.

Apparatus for the mechanical cleaning of a cold-water stream

In the operation of cleaning the pipes of heat exchangers by means of sponge rubber balls which are entrained by the cooling water, a cylindrical housing is connected upstream of the heat exchanger, in which housing several chambers are formed by several dividing walls rotating about a vertical axis, and the chambers are subdivided by a horizontal sieve plate into an upper group of chambers for receiving the balls and into a lower group of chambers. In this arrangement, two opposite cooling water supply and removal connections are each provided in the region of the lower group of chambers, and two similar cooling water connections are provided in the region of the upper group of chambers which are connected to the heat exchanger pipes. In order to also allow a discontinuous cleaning operation, while stopping the balls and without interrupting the flow of cooling water, the present invention provides that the interior of the housing (2) is subdivided by three dividing walls (4,5,6) which are arranged at 120.degree. to one another, into three equal chambers (7, 8, 9), each cross-sectional surface of which is approximately the same size as the cross-sectional surface of one of the cooling water connections (11 . . . 14).
