A cleaning apparatus has a hollow input shaft connectable to a hydraulic pressure source, is received in a first housing part and has a fluid conduit, with at least one lateral or axial input and at least one lateral output. At least one hollow output shaft is fluidically coupled to the hollow input shaft, received in a second housing part, and has a fluid channel, with at least one lateral input and at least one lateral or axial output. The hollow input shaft and/or the hollow output shaft is/are mounted rotatably about the longitudinal axis thereof relative to the relevant housing part. A first chamber is at least between the input or output of the hollow input shaft or the input of the at least one hollow output shaft and an interior lateral surface of a sealing sleeve. The sealing sleeve is fixed in a stationary and non-rotatable manner on the relevant housing part and arranged surrounding a portion of the hollow input or output shaft. Regions of the interior lateral surface of the sealing sleeve extending axially from the first chamber form a gap seal with the exterior lateral surface of the hollow input or output shaft.

A device for applying a viscous material includes an application tube which has a material inlet opening on a first end and a material outlet opening on a second end, which defines an application channel, and which is flexible at least over one portion of its length, and a housing which accommodates the application tube, and which has a material supply connection for the viscous material to the application tube, wherein the application tube is connected to the housing in an initial region coming from the material inlet opening, and is arranged at a distance to the housing in an end region extending to the material outlet opening, and wherein a bearing section of the end region is mounted near to the material outlet opening in a motor-driven eccentric that can rotate about the longitudinal central axis. An adjustment mechanism is provided for adjusting the distance of the bearing section to the longitudinal central axis.

A spray cleaning device for cleaning the interior of a vessel or the like through an access opening in an underside thereof. The cleaning device includes a wheeled carriage positionable in selected relation to a vessel to be cleaned, an elongated frame having a central drive shaft extending along its length, and a rotatable spray head supported in an upstanding relation to a downstream end of said elongated housing for rotation about multiple axes. The elongated frame is pivotably supported by said wheeled carriage for selective positioning of the spray head within the vessel to be cleaned, and the spray head has a liquid supply which communicates with a liquid inlet to an upstanding support thereof downstream of the central drive shaft so said liquid is not transmitted along the drive shaft.

A showerhead assembly is provided having a primary showerhead which is relatively traditional in construction and includes a hollow housing and a plurality of spray nozzles. In addition, the showerhead assembly includes an orbiting showerhead which rotates about the primary showerhead's central axis. The primary showerhead is connected to a water source by a neck portion having a female threaded inlet. Meanwhile, the orbiting showerhead is rotatably connected to the neck portion by a collar and elbow conduit. Preferably, the orbiting showerhead can tilt inwardly and outwardly with respect to the elbow conduit thereby allowing the spray from the orbiting showerhead to tilt inward or outward relative to the spray from the primary showerhead.

Parameters for a plurality of motors that move a nozzle on a three-dimensional movement locus are set easily. A washing device 1 includes display device 7, and a worker touches an input unit 7A of the display device 7 with a finger, to thereby set parameters for both servo motors that move a nozzle 3 on a three-dimensional movement locus. Specifically, a three-dimensional model Md1 of a tank 2 to be washed is displayed on the input unit 7A, and next, the worker drags specific spots of the three-dimensional model Md1, sequentially, and selects washing methods and washing time periods of the spots. The selected contents are transmitted to a control device 6, are computed by a computing unit 6A of the control device 6, so that the parameters for both servo motors for operating the nozzle 3 in three dimensions are set in washing.

Systems, devices, and methods for passing railcar tank cleaning systems through the opening and mounted to existing manways. The invention can extend horizontally more than 25 feet and clean rail cars up to and beyond approximately 102 inches in diameter for manual, automated, or semi-automated programmable railcar tank cleaning systems, devices and methods for providing safe and efficient methods for breaking up oil, tar, chemical, radioactive, hazardous, or any other liquid, solid, or sludge waste inside rail tank cars and the like with nozzles which utilize fluid jets to break up, liquefy, and motivate tank material. The programmable railcar cleaning system can be a standalone, independent unit or integrated into new designs and/or existing systems. Simplified programming and user interface allow an operator to remotely operate the system. The various capabilities of this invention allow cleaning in a quicker and more efficient manner. The system is hydraulically controlled and can work in the presence of flammable vapors and dust.

In processing a peripheral edge part of a substrate by a processing liquid, upward scattered liquid droplets may be produced. Accordingly, in the invention, the processing liquid is caused to land on the peripheral edge part of the substrate from a discharge port while the discharge port is positioned to a bevel processing position lower than an eaves part of a cup in a vertical direction with the peripheral edge part of the substrate covered vertically from above by the eaves part. Thus, the eaves part collects upward scattered liquid droplets. As a result, the re-adhesion of the upward scattered liquid droplets to the substrate and the scattering thereof to a surrounding atmosphere are suppressed.

The present invention relates to a cleaning in place nozzle system (1) for cleaning surfaces of complex shape, comprising a first body part (21) comprising a dry section (22) and a fluid section (23), a second body part (25) coaxially arranged in the first body part, a nozzle part (26) having a nozzle axis (NA), a fluid inlet (24) arranged in the first or second body part and a fluid outlet (27) arranged in the nozzle part wherein the nozzle system is operatively connected to an intelligent control unit (28) for controlling rotational movement of the nozzle part and/or the body parts. The invention further relates to a method for cleaning a container using a cleaning in place nozzle unit.

Manual, automated, or semi-automated programmable tank cleaning nozzle systems, devices and methods for providing safe and efficient methods for breaking up oil, tar, chemical, radioactive, hazardous, or any other liquid, solid, or sludge waste inside storage tanks, ballast tanks, floating roof tanks, void tanks, rail tank cars and the like with nozzles which utilize fluid jets to break up, liquefy, and motivate tank material. The programmable tank cleaning nozzle incorporates two degrees of freedom and can be mounted to existing booms, robotic arms, gantry systems, rigid beams, manways, or any other rigid structure. The programmable tank cleaning nozzle can be a standalone, independent unit or integrated into new designs and/or existing systems. Simplified programming and user interface allowing an operator to remotely operate the system without the need for a camera system.
