Abstract: A rotary apparatus and method is provided for cleaning liquid storage tanks, particularly above ground tanks. The rotary cleaning apparatus includes a Tee housing that is rotated around a vertical axis and a nozzle housing mounted to the Tee housing for rotation around a horizontal axis, resulting in a 360° spherical spray pattern. A set of downspray nozzles is mounted to the Tee housing at an angle to the vertical axis to rotate with the housing and generate a conical spray pattern. In the preferred embodiment, the apparatus draws liquid stored in the tank through a filter and pumps the filtered liquid through the rotary cleaning apparatus.

Abstract: An apparatus for cleaning vessels stacked on racks with a minimum of head clearance. The cleaning apparatus has a drive unit with a turbine wheel connected to a multi-stage gear train. The output motion of the gear train connects through an angular transmission within a fluid conveying elbow to a rotatable housing having a rotatable nozzle angularly assembled thereto. The elbow has a pressure channel and a suction channel there through. The length of the apparatus from the elbow to the housing is short enough to be passed into the bunghole of a vessel, e.g. a wine barrel, while racked. A flexible suction hose is connected to a suction line in the apparatus for removing spent cleaning fluid from within the vessel.

Abstract: A preferred embodiment of a system for cleaning a restroom includes a pump for pressurizing a fluid, and a spray device in fluid communication with the pump. The spray device has a nozzle for discharging a stream of the fluid. The system also includes a stand for supporting the spray device within an enclosure of the restroom while the spray device discharges the stream at an interior surface of the enclosure, and a cover for suspending the spray device in a holding tank of the restroom while the spray device discharges the stream at an interior surface of the holding tank.

Abstract: An apparatus for cleaning the interior of a vessel for containing a sanitary product by ejecting a rotating stream of cleaning fluid. The apparatus features a stationary housing that forms an inlet for receiving a flow of cleaning fluid, a rotatable housing mounted for rotation on the stationary housing about a first axis, and a nozzle for ejecting the cleaning fluid, the nozzle being rotatably mounted on the rotatable housing so that the nozzle rotates about a second axis. A planetary gear train is driven by an impeller driven by the flow of cleaning fluid and drives the rotation of the rotatable housing. The planetary gear train is located between the apparatus inlet and the nozzle.

A gear train is located between the inlet and the nozzle. In addition, a first gear, which, along with the gear train, drives rotation of the rotatable housing about the first axis, and a second gear, which drives the rotation of the nozzle housing about the second axis, are disposed on opposite sides of the second axis. A deflector deflects fluid running along the input drive shaft away from the gear train housing and a passage drains the deflected fluid to the surrounding environment.
