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.

Apparatus for cleaning a tank's inner side includes a tank-mountable frame, a frame-mounted support drivable with respect to the frame about a first rotation axis, a support-mounted nozzle drivable with respect to the support about a second rotation axis transverse to the first axis. The nozzle's spraying direction faces away from the second axis. A controller of the apparatus drives the support and the nozzle, such that the nozzle is rotated about the second axis alternatingly from a start position to a stop position by a predefined cleaning angle smaller than one revolution and from the stop position to the start position. The nozzle angular velocity with respect to the support is smaller than the support angular velocity with respect to the frame within the cleaning angle and smaller than the nozzle angular velocity with respect to the support during movement from the stop position to the leaning start position.

A method of cleaning drilling fluid tanks is provided. The method includes washing drilling fluid within a first tank with fuel oil thereby forming a first admixture of drilling fluid and fuel oil. The method further includes reclaiming the first admixture and washing drilling fluid within a second tank with the reclaimed first admixture. The method further includes reclaiming a second admixture formed by the first admixture and the drilling fluid from the second tank. The method further includes washing drilling fluid within a third tank with the reclaimed second admixture.

The present disclosure provides a system and method articulating and rotary spray system for fluids that includes a first drive for rotating a mast for different headings and a second drive for rotating a nozzle for different pitches at any time with or without rotation of the mast. The method and system uses a system of interacting gears that rotate a control rod in variable synchronization to control the nozzle pitch relative to the mast heading while the control rod orbits about a center of rotation of the rotating mast along a longitudinal axis.

A washing device 1 includes an inner tube 13 pivotally supported rotatably, a turning shaft 14 provided in a direction substantially orthogonal to the inner tube 13 and pivotally supported rotatably at a distal end of the inner tube 13, and a nozzle 3 provided on the turning shaft 14, and the nozzle 3 is rotated in a revolving direction and in a rotating direction by a first motor 25 and a second motor 28. A revolving direction model 41a for setting an operation of the nozzle 3 in the revolving direction and a rotating direction model 41b for setting the operation of the nozzle in the rotating direction are displayed on display means 7, and a movement locus of the nozzle is prepared from the set operations of the nozzle in the revolving direction and in the rotating direction.

The present invention relates to a nozzle arrangement and method for removing solids and/or fluids, such as sludge, preferably suspended or contained in fluid, from tanks such as oil/mud-tanks and other similar difficult accessible deposits and tanks/tanks. In preferred embodiments, the nozzle arrangement has a rotating mechanism (8) comprising a primary drive shaft (13) being connected to a pipe section (4), a row of gear teeth (9) fixedly arranged on or formed in lower end of a down pipe (3) on an outside thereof, an angular gear (10), a worm gear (16) arranged to rotate an angled nozzle pipe section (7) at the cleaner head (5) driven by the angular gear, a secondary drive shaft (11) rotatably mounted on an outside of said pipe section (4) and having at one end a gear wheel of the angular gear (10) and at the other end a gear wheel co-operating with said row of gear teeth (9).

A fluid handling apparatus for ejecting fluid into a tank and draining fluid from the tank comprises: a fluid duct for draining/supplying fluid from/to the tank, the fluid duct configured for fluid communication with a tank opening at a tank bottom; a fluid inlet pipe for supplying fluid to the tank, the fluid inlet pipe extending at least partly through the fluid duct and configured to extend through the tank opening into the tank; a rotary fluid ejection device in fluid communication with the fluid inlet pipe; and a rotary drive shaft extending at least partly inside the fluid inlet pipe, the rotary drive shaft being rotatably connected to the rotary fluid ejection device. Also disclosed is a fluid tank system comprising a tank and a fluid handling apparatus, and a method for mixing beer or wort with solid hops material in a tank by a fluid handling apparatus.

The present invention is directed to providing a front opening unified pod (FOUP) cleaning device capable of improving cleaning and drying efficiency for a FOUP body and a FOUP cover and a FOUP cleaning method. To this end, the FOUP cleaning device for cleaning a FOUP including a FOUP body and a FOUP cover includes: a loading and unloading part configured to load or unload the FOUP; a standby part which is provided at one side of the loading and unloading part and on which the FOUP body and the FOUP cover are separated from or coupled to each other; a cleaning chamber configured to clean the FOUP body and the FOUP cover using steam; and a robot configured to transport the FOUP body and the FOUP cover between the standby part and the cleaning chamber. The FOUP cleaning method for cleaning a FOUP including a FOUP body and a FOUP cover includes loading the FOUP on a loading and unloading part; transporting the loaded FOUP to a standby part; transporting the FOUP body and the FOUP cover transported to the standby part to a cleaning chamber using a robot; and cleaning the FOUP body and the FOUP cover by supplying steam into the cleaning chamber.

A rotating cleaner (1) comprising a housing (2) which has a cavity (10) and an inlet (9) which is connectable to a fluid supply line, a shaft (5) extending in sections into the cavity (10), a sprayer body (3) which is non-rotatably connected with the shaft (5) and has an outlet (8), and further comprising a sliding bearing for rotatably supporting the shaft (5) in the housing (2), said sliding bearing having a rotating bearing surface (23), an idle bearing surface (22) and a bearing gap. To improve the cleanability and the rotational characteristics of the rotating part, it is proposed that the rotating bearing surface (23) and the idle bearing surface (22) are each formed as a contiguous surface for supporting the shaft (5) in the radial and axial direction.

A system comprising a mixer with a rotary head fitted with a nozzle for ejecting liquid into a container. At least one drive member rotates the rotary head such that liquid is ejected into the container in a predetermined pattern. A processing unit is configured to receive first and second operation parameters that are representative of mixing of a liquid content of the container respectively cleaning of an inner surface of the container. The processing unit then controls the drive member in response to the operation parameters such that mixing respectively cleaning is effected. A related method and a computer-readable medium are also described.
