A scarifying rig may be mounted on the surface of a floating roof to move about the perimeter of the roof. The rig comprises a trolley, one or more support rails fixed on the trolley, and a horizontal arm mounted on the support rails for controlled movement along the support rails. A vertical rail is attached substantially to the end of the horizontal arm for reciprocating vertical movement (up and down) about the end of the horizontal arm. A nozzle assembly is mounted to the vertical rail.

The invention relates to an item-to-be-cleaned carrier for the cleaning of items to be cleaned, which have at least one cavity, the cleaning being performed in a conveyor washer. The item-to-be-cleaned carrier can be used in particular for cleaning personal protective equipment. The item-to-be-cleaned carrier comprises at least one base element and at least one nozzle tube, which is connected to the base element. The nozzle tube has at least one inlet opening having at least one catching funnel . The nozzle tube has at least one outlet nozzle. The nozzle tube tapers, at least in parts, from the inlet opening to the outlet nozzle. The invention further relates to a cleaning system and to a method for cleaning items to be cleaned, which have at least one cavity, using the cleaning system.

Disclosed is a barrel cleaner (10), including a cantilevered lift to raise a barrel, bearings (31, 32) to permit rotation of the barrel once raised, and a spray head support (20) including a spray head. In use the barrel may be rotated so that a bung hole of the barrel is in an insertion position, and the support can be operated to insert the spray head into the bung hole.

A cleaning device for a vessel includes a base body, a valve, a spray body, a restoring device, a release mechanism and an actuating element. The base body includes a connector, the valve is disposed between the base body and the spray body and the valve is operable by the release mechanism against a restoring force applied by the restoring device, the actuating element being disposed on the release mechanism and the actuating element includes at least one leg forming a supporting surface for a vessel and the spray body includes a spray head disposed above and at a distance from the supporting surface, the restoring force being greater than the sum of the gravitational forces of the vessel, the release mechanism and the actuating element.

The disclosure is directed to an apparatus, system and method for cleaning interior surfaces of storage containers such as tank trailers and other surfaces using a low volume of high pressure fluid. The apparatus of this disclosure includes one or more high pressure fluid conduits that can be extended and retracted within a storage container.

A tank cleaning system for cleaning a space. The tank cleaning system can include a trailer having a support base transportable by a vehicle, and an arm movably mounted to the support base for movement relative to the support base. The arm can be operable to extend into the space to perform a cleaning operation inside the space.

A containment tank assembly is described that includes a tank including an inner surface and a cleaning apparatus mounted to the tank. The cleaning apparatus includes an elongate arm and a rotary spray head assembly rotationally coupled to an end of the elongate arm. A rotating nozzle assembly is rotationally coupled to the rotary spray head. A magnetic field source is coupled to the rotary spray head so as to generate a spatially changing magnetic field in accordance with a rotation of the rotary spray head assembly in relation to the end of the elongate arm. A magnet field sensor is carried in a fixed relation to the elongate arm. The magnetic field sensor, in operation, generates a sensor signal that varies in accordance with the spatially changing magnetic field in accordance with the rotation of the rotary spray head assembly.

A cavity cleaning and coating system for safely and efficiently cleaning and coating the interior of a cavity without requiring entry of any workers. The cavity cleaning and coating system generally includes a mount which is coupled with a movable arm of a vehicle. The mount includes an inner plate, which is coupled to the arm, and an outer plate. A shaft is coupled to the outer plate. The mount is adjustable independently of the arm of the vehicle, including outwardly, inwardly, and rotatably. A spray head is connected to the shaft. The spray head is rotatable and includes a dispenser for dispensing fluids. The vehicle is positioned near a cavity to be treated. The mount is adjusted for optimal positioning of the spray head. The spray head is lowered into the cavity to dispense a cleaning fluid and, after the cleaning fluid has dried, a coating fluid.

Various embodiments relate to devices and methods for treating a mixture of expansion gas and filling product foam in a beverage filling plant, comprising the steps of introducing the mixture of expansion gas and filling product foam into a closed separation container and extracting the expansion gas out of the closed separation container via suction.

The present invention provides a home pot. The home pot comprising: a housing having a cylindrical accommodation space of which the upper part is open and in which a nozzle tip can be accommodated, and has n injection flow paths formed on a sidewall in contact with the accommodation space; and a cleaning liquid supply portion provided in the housing and configured to supply a cleaning liquid to the n injection flow paths, and the n injection flow paths are disposed to be inclined with respect to the center of the accommodation space such that a high-speed swirling flow is generated in the accommodation space.
