Apparatus and method for removing debris from water management systems

摘要

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.

主权项

1. A mechanically conveyed waste water system and apparatus, comprising:
a basin for waste water retention having at least one inlet pipe; a mechanical waste water conveyance device for removing waste and water from the basin; a bar screen including at least three sides, a frame, and a plurality of spaced apart parallel bars connected to the frame, at least one of the plurality of bars having either a slope up or a slope down portion and an approximately flat portion; a mounting bracket for attaching the bar screen approximately directly below the mouth of the inlet pipe and including a mounting block that the bar screen is coupled to and a circular collar connected to the mounting block and for attaching the mounting bracket to a wall surface around the inlet pipe, so as to catch and remove unwanted debris from an incoming stream of fluid including debris; and a bar attached to the mounting bracket upon which the bar screen is retractably and/or removably mounted so that the bar screen is retractable and/or removable for maintenance and/or waste water pump removal.
