An improved game washer is compatible with a variety of receptacles and includes one or more cradles for receiving and holding various types of game. Agitation for washing game is provided via one or more water flows at one or more outlets of an agitator. An outlet engages a bottom of a cradle to provide water flow at the cradle. The agitator extends out of an opening of a receptacle at a central portion thereof to receive a water supply, while forming a gap at the opening to permit a flow of water and waste material out of the receptacle.

The present disclosure may provide a cleaning apparatus for cleaning parts. The cleaning apparatus may comprise a housing defining a washing chamber having an opening through which parts may be loaded/unloaded into the washing chamber. The cleaning apparatus may also comprise a spray system adapted to direct a washing solution to clean the part in the washing chamber. The spray system may comprise a spray array with at least one rotatable spray head. The spray head may comprise a plurality of nozzles through which the washing solution is directed to clean the part in the washing chamber. The cleaning apparatus may also comprise a closure which may provide controlled access to the washing chamber through the opening and may be movable between a closed position to sealingly close the opening and an open position so as to allow for loading and unloading of parts into the washing chamber without obstruction.

A mobile washing system and methods for washing photovoltaic panels. The mobile washing system includes a vehicle, a fluid tank coupled to the vehicle, and a washing apparatus mounted to a side of the vehicle. The washing apparatus includes two generally longitudinal spray pipes that are configured to be rotated and vertically adjusted with respect to the vehicle to position the spray pipes generally parallel to a top surface of the photovoltaic panels.

A cleaning fluid includes a static liquid (13) at a first temperature, a dynamic liquid (16) that flows toward an object held in the static liquid (13), and a fine gas bubble group (22) formed from a gas at a second temperature that is different from the first temperature, the gas being entrapped by a flow of the dynamic liquid (16) and flowing toward the object. This can provide a cleaning fluid that exhibits a remarkably better cleaning effect than ever before.

A cleaning method includes controlling an unmanned aerial vehicle (UAV) to fly to a region of a wall body according to a path to be cleaned, and, in response to detecting a cleaning prohibition identifier associated with the region, recognizing the region as a cleaning prohibition region and controlling the UAV to fly over the cleaning prohibition region without cleaning the cleaning prohibition region.

A cleaning method allows reliable cleaning of thread roots of a female screw. A cleaning method for a female screw includes producing a jet of a cleaning liquid from a nozzle in a direction tilted from an axis of the female screw without inserting the nozzle in the female screw, and directing the jet to impinge on a thread of the female screw while rotating the jet about the axis.

A method of cleaning an inner wall surface (502) of a bell jar (500), by causing nozzles (112, 122) to discharge a cleaning liquid which contains abrasive particles, includes the steps of: (a) causing the nozzles (112, 122) to discharge the cleaning liquid at a discharge pressure at which erosion of the nozzles (112, 122), due to the cleaning liquid, occurs by not more than 500 m/hour; and (b) adjusting a distance between the inner wall surface (502) and the nozzles (112, 122) so that an impingement pressure, at which the cleaning liquid impinges on the inner wall surface (502), secures a pressure at which dirt on the inner wall surface (502) can be removed.

A washing cabinet for cleaning a part. The washing cabinet comprising: a sonication tank configured to contain a volume of liquid; at least one ultrasonic transducer configured to direct ultrasonic energy into the liquid in the sonication tank; a spray chamber disposed above the sonication tank; a spray system configured to direct liquid into the spray chamber; a part holder configured to support a part to be cleaned in the washing cabinet; a catch tray; an actuator system coupled to the part holder and the catch tray; the actuator system configured to move the part holder between an upper spray position in the spray chamber and a lower sonication position in the volume of liquid in the sonication tank; the actuator system configured to move the catch tray between a first tray position in the spray chamber and a second tray position; the catch tray positioned between the part holder and the sonication tank when the part holder is in the upper spray position and the catch tray is in the first tray position in the spray chamber; a liquid retaining tank separate from the sonication tank; and the catch tray having a tray outlet configured to direct liquid into the liquid retaining tank when the catch tray is in the first tray position in the spray chamber.

A method for cleaning a wall body with a UAV includes obtaining a path to be cleaned; flying to a region to be cleaned according to the path to be cleaned; recognizing a wall surface in the region to be cleaned; and using a cleaning device carried by the UAV to clean the wall surface.

The invention relates to a module for chemically processing a substrate, a method for chemically processing a substrate and a use of a module for chemically processing a substrate and in particular a large substrate. The module for chemically processing a substrate comprises: an immersion chamber, a spray unit, and a motion unit (14). The immersion chamber is configured to receive a first liquid and the substrate, so that the substrate is immersed in the liquid. The spray unit comprises a plurality of spray nozzles, which are configured to spray a second liquid within the immersion chamber. The motion unit is configured to provide a relative motion between the substrate and the spray unit.
