Abstract
The present invention is directed to a debris catching and removing apparatus and method. For example, bar screens or grids for collecting and removing trash or debris from storm, waste water, or sewage systems, and mounting systems and methods therefore are provided. These apparatus and method may provide a long-lasting, light-weight, and low-cost debris screen screening solutions for removing trash or debris from, for example, storm, waste water, or sewage systems. The invention may be particularly applicable to small lift stations that use submersible pumps or surface mounted pumps that suction waste water from a wet well.
Claims20
A removable bar screen apparatus for removing debris from a stream of fluid, comprising:
- a bar screen attached to an inlet pipe with a band, wherein the band is placed around and contacting at least a portion of an outside surface of the inlet pipe, so that the bar screen is supported by the inlet pipe, wherein the bar screen includes a plurality of straight spaced apart bars with upper surfaces that form a platform or floor for debris to fall into.
A removable quick connect/disconnect debris screening and catching apparatus for quickly and easily removing debris from an inlet source of a basin, comprising:
- a screen removably connected to and below an inlet pipe of a lift station such that the screen may be removed, cleaned, and returned to below the inlet pipe of the lift station, wherein the screen includes a plurality of straight spaced apart bars with upper surfaces that form a platform or floor for debris to fall into and a front side portion of the spaced apart bars that is angled upward relative to at least the upper surfaces of the spaced apart bars and upward toward the level of a mouth of the inlet pipe, so as to keep debris from sliding off an end of the length of the plurality of spaced apart bars;
- and
- a band placed around and contacting at least a portion of an outside surface of the inlet pipe so that the screen is supported by the inlet pipe.
A waste water and/or storm water debris retention and removal apparatus, comprising:
- a basin;
- a bar screen;
- an inlet pipe extending into an open area of the basin;
- and
- a band placed around and contacting at least a portion of an outside surface of the inlet pipe, so that the bar screen is supported at least in part by the inlet pipe, wherein the bar screen is oriented in a horizontal position relative to a vertical wall of the basin and located below a mouth of the inlet pipe.
