Patent DE-2833816-A1 (DE)
Inventor: KOESSLER ERICH ING
IPC: E02B8/02
Filed: 1978-08-02
Abstract: The cleaning rake is provided with a rake beam (1), the part of which facing the water flow has a streamlined profile (2) in cross-section and which has its largest width at its end area turned away from the water flow and forms two water-separation edges there. There is a plane wall (5) between the sections (4, 8) of the rake beam (1) which form the water-separation edges. The plane wall (5) runs parallel to the plane defined by the bars of the screen (13). This cross-sectional shape of the rake beam results in a large mechanical section modulus and only slight turbulence so that material (16) deposited on the screen is no longer swirled up. The plane wall (5) dampens the falling movement when the cleaning rake falls from the downward guideway (11) into the upward guideway (12). <IMAGE>
