  • Patent number: 8038889
    Abstract: A screen cleaning apparatus for use, for example, in connection with a discharge conduit of a sewage pumping station, may include a housing, a screen, a rake and a float. The housing may operate to contain a fluid (and/or define a container for the other components) and include a fluid inlet and a fluid outlet. The screen may be positioned in the housing and define one or more apertures. The rake may also be positioned in the housing and have one or more protrusions, with each protrusion extending into a respective aperture in the screen. The float may apply a force to the rake so that the rake moves relative to the screen and in dependence upon variations of a volume of fluid received in the housing. Accordingly, the rake may rise and fall will the fluid level to remove debris from the screen.
