Sediment collection header apparatus

摘要

A header conduit assembly for a sediment collecting apparatus includes a tubular member having a plurality of mutually spaced (suction) orifices disposed in a linear array extending parallel to an axis of the tubular member. The conduit assembly further includes at least one elongate deflector member mounted to the tubular member in effective proximity to at least some of the orifices to guide sediment toward the orifices during a sediment evacuation process. Preferably, the deflector member extends parallel to the axis of the tubular member. Inasmuch as the tubular conduit member extends perpendicularly to a direction of movement of the conduit assembly on the floor of a clarification basin or tank, the deflector is oriented orthogonally to the path of the conduit assembly.
