ABSTRACT:
A spray cleaner (10) is provided for rotatingly cleaning an interior of a vessel or the like. The spray cleaner has a main body (12) and a rotating spray body (14). The main body is at a proximal end of the spray cleaner, and the rotating spray body is at a distal end of the spray cleaner. An internal flow conduit (22) in the main body of the rotating spray body communicates a fluid inlet in the main body to a plurality of spray nozzles (18) in at least one spray head which is a part of the rotating spray body. A drive train (30) for rotating the spray body is positioned in the main body, such that the flow conduit passes around the drive train in an annular passage coaxial with the drive train, providing cooling thereto. A vaned rotor (26) in the flow conduit is connected to an input shaft (28) of the drive train, which transfers torque to an output drive system (42) that is fixedly connected to the rotating spray body. The rotation of the rotating spray body relative to the main body about a longitudinal axis of the cleaner effects rotation of the at least one spray head about a radial axis of the cleaner. A planetary gear set (36) may be used as the drive train.
