A washing apparatus for a 3D-printed article is provided for the removal of support material from the article. The apparatus includes a glove isolation cabinet with a liquid-discharging nozzle to enable an operator to spray an article with a washing liquid, and a drain. A first filter arrangement receives liquid discharged from the cabinet. The washing liquid drains through the first filter arrangement under the influence of gravity but the first filter arrangement is located in a trough in which washing liquid that has passed through the first filter arrangement accumulates whereby, in use, one or more filters of the first filter arrangement are submerged to ensure filtered-out residue remains submerged in the washing liquid. A pump is provided to pump liquid that has passed through the first filter arrangement through a second filter arrangement adapted to filter out solid material equal to or greater than 5 μm in size.

The invention relates to a portable overnight degreasing system, a work station and a method of use. The invention includes a portable soak tank with a disposable liner bag liner removably placed within the interior of the soak tank. The liner bag is then filled with a cleaning solution and soiled items are lowered into the bag liner upon removable grates. An agitator pump is positioned within the portable soak tank to agitate the cleaning solution. The soiled items remain within the locked soak tank overnight or until grease and carbon falls off of the soiled items. An optional heater may be used within the soak tank to increase the speed of degreasing. The soak tank also includes a slanted floor that funnels fluid from the interior of the soak tank into a pipe that connects to a valve on the front wall of the soak tank. Fluid is removed from the system through the valve and then the empty liner bag is disposed. When used as a workstation, a protective cover is placed over the lid and upper portion of the soak tank and a cutting board is placed over the protective cover in a recessed pocket for use by kitchen staff.

A portable system for washing tools is disclosed. The portable system includes a first receptacle, a second receptacle, and a filtering assembly engaged with one of the first and second receptacles. The filtering assembly is configured to engage with and communicate water from one receptacle for washing tools. The water and any mud are collected in the other receptacle. When water is depleted from a receptacle, the filter assembly is transferred to the other receptacle for reuse of the water wherein the process is repeated. The filtering assembly includes a displacement element for creating a distance between a water input port and any mud at a gravitational bottom. The filtering assembly can subsequently be moved back and forth between each receptacle for continue reuse of the water for cleaning tools.

An apparatus and method for removing support material from a part formed by three-dimensional (3D) printing. The support removal machine contains a tank for submersion of a 3D printed part into a liquid mass. The liquid mass circulates in the tank in a controlled manner such that submerged parts remain centrally suspended in the tank, regardless of the material, density and geometry comprising the part. The part circulates and rotates in conjunction with the rotational flow of the liquid mass for uniform exposure to means of support removal. During rotation, the part may be subjected to multiple means of agitation that include heat, chemical and ultrasonic, in order to optimize energy use and maximize efficiency of the removal of support material.

A washing machine and/or a fluid flow structure for a washing machine wash tank is provided. The wash tank is generally rectangular and includes a bottom wall, two side walls and two end walls extending upwardly from said bottom wall. The wash tank further includes at least one flow directional opening in at least one of the walls. In a preferred embodiment, the wash tank includes a plurality of flow directional openings positioned along one of the side walls of the wash tank. A fluid flow structure is located within said wash tank, which includes a fluid flow guide surface, and a support for said guide surface. The guide surface includes an expansion structure that is designed to counteract expansion of the guide surface that occurs during operation of the washing machine. In one embodiment the expansion structure is an expansion slot that engages a portion of the guide surface. As the guide surface expands the expansion slot is pressed against the portion of the guide surface, causing the expansion slot to expand into a relief area associated with the expansion slot at a location generally opposite of the portion of the guide surface.

A parts washer for washing parts includes a housing defining an interior that receives the parts. The interior includes a washing fluid reservoir to hold a washing fluid, the washing fluid reservoir having a washing fluid fill level. A soak basket receives the parts and is disposed in the washing fluid reservoir such that at least a portion of the soak basket is disposed below the washing fluid fill level for soaking the parts when the reservoir is filled with washing fluid. A part support platform is in the interior of the housing. The part support platform has a part support surface for supporting some of the parts thereon. The part support surface is above the washing fluid fill level. A washing system washes the parts on the part support surface.

A cleaning and distillation apparatus with a clean fluid tank, a cleaning tank, a recirculating fluid tank located below the cleaning tank, a removable separator panel partitioning the clean fluid tank from the recirculating fluid tank, a distillator and an outlet for dispensing fluid is provided. Also provided is a cleaning apparatus, without the distillator, the cleaning apparatus having a cleaning tank, a recirculating fluid tank located below the cleaning tank, a removable separator panel partitioning the recirculating fluid tank from the cleaning tank, and a fluid dispenser.

A cleaning system for use with a filter is described herein. The cleaning system includes a housing including a main enclosure defining an interior sized to receive the filter, a collection vessel coupled in communication with the housing, and a nozzle configured to direct a stream of air towards the filter to dislodge particles from the filter. A pneumatic suction device is coupled in communication with the collection vessel, wherein the pneumatic suction device is configured to draw the particles dislodged from the filter towards the collection vessel.
