Dual weir vortex skimmer

摘要

A skimmer system for removing a substantially liquid substance such as oil floating on the surface of a body of water has a reservoir body defining an collected fluid reservoir and having a primary weir edge. A weir tube extends upwardly within the reservoir and provides a secondary weir edge being of less height than the primary weir edge and defines a vortex chamber. A plurality of buoyancy members support the reservoir body in relation to the surface of the body of water and are adjustable relative to the reservoir body by power operated or mechanical devices for selective positioning of said primary weir edge relative to the water surface. A pump having a suction inlet is in communication with the vortex chamber and has a discharge outlet conducting recovered oil to a collection barge. A power source such as a hydraulic fluid supply is connected in driving relation with the pump.
