Abstract
Crude oil tank cleaning apparatus includes a gimbal having a substantially straight passageway extending therethough. A mounting bracket sealingly and rotatably mounts the gimbal in a wall of the tank so that the gimbal has an interior side exposed to the interior of the tank and an exterior side exposed to the exterior of the tank. A straight pipe is sealingly mounted in the gimbal passageway. The pipe has an inlet end on the exterior side of the gimbal for connecting the pipe to a high pressure fluid source and an outlet end on the interior side of the gimbal such that the inlet and outlet ends define a linear flow passageway through the pipe for discharging the fluid in fluid jet into the tank. An actuator, mounted on the exterior of the tank, has a first end connected to a rotatable portion of the gimbal and a second end connected to a stationary portion of the tank or the mounting bracket for reciprocating the gimbal and pipe between selected positions.
