Mechanically assisted hydraulic filter

摘要

A filter system for removing a material from a layer of water of selected depth beginning at the surface of a body of water. The system is designed to be mounted to a surface vessel specially adapted to receive the system. The surface vessel has an intake area at its bow. A water intake gate acts as a closure to the intake area. The inlet gate can be lowered to admit water to the intake area as the vessel is propelled through the body of water. An endless conveyer type filter screen is supported by rollers in the intake area. Water passing through the filter screen is discharged through ducts passing through the sides of the vessel. Material separated from the water is conveyed by the filter screen to other equipment for further processing.
