ABSTRACT:
The invention describes a device for recovering oil floating on the surface of water. The device is a floating vessel which is maneuverable at will in order effectively to recover all of an oil slick floating on the surface of the water. The device includes paddle wheel means to skim the oil from the surface of the water. The oil so picked up is propelled up guide plates, and over weirs, with a plurality of said wheels being arranged in sequence. The wheels are of different diameter but rotate at the same speed in order to provide separation of oil and water picked up by the device, and the device is also arranged to discharge the oil into a means from which the oil can readily be transported away from the device.
The device may be provided with an additional wheel and screen for picking up debris floating on the surface of the water, and to separate that debris from the oil and water picked up by the device by leaving it on the screen.
