An apparatus and method of restricting entry velocity into a tank is provided. To this end, a throttle plate is utilized to reduce circulation turbulence and significantly reduce the probability of damage to fragile articles undergoing deglazing, defrosting, washing or other circulation within a fluid tank. The throttle plate includes a main body with a top, bottom, and opposing sides and is configured to interface with a wash tank in a variety of throttle plate conditions. The main body of the throttle plate sits substantially against an interior wall of the wash tank, partially obscuring one or more inward flowing jets associated with the wash tank. Such obscuring dampens or throttles the flow of water from the jets into the wash tank. The throttle plate is adjustable; thus, a user of the wash tank can utilize the throttle plate to selectively control the flow of water into the tank.

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 portable parts washer for cleaning mechanical parts that includes a washer body having an upper portion, a lower portion, and a wash basin formed within the upper portion having inner sidewalls, a floor panel and at least one drain aperture. The portable parts washer also includes an in-use reservoir formed within the lower portion of the washer body and having a bottom panel spaced from the floor panel and outer sidewalls, and which is configured to receive cleaning fluid from the wash basin through the drain aperture when the floor panel is in a substantially horizontal orientation. The portable parts washer further includes a storage reservoir formed within the upper and lower portions and which is configured to contain the cleaning fluid from the in-use reservoir when the floor panel is rotated to a substantially vertical orientation.

An example flush station includes an upper cabinet and a lower cabinet. At least one cleaning head is mounted in the upper cabinet, and has an anchoring attachment, a cleaning solution inlet to dispense cleaning solution, and a compressed air inlet to dispense compressed air. A vacuum system may be provided in the upper cabinet to entrain airborne particulates. A catch basin formed in the lower cabinet receives spent cleaning solution from the upper cabinet. At least one settling tank in the lower cabinet receives spent cleaning solution from the catch basin for settling at least some suspended particulate matter in the spent cleaning solution. A grate at an interface between the upper section and the lower cabinet provides a cleaning deck for filters and/or other components to be cleaned during the cleaning operation. During the cleaning operation, cleaning solution and/or compressed air are dispensed through the filters and/or other components.

The portable parts washer also includes an in-use reservoir formed within the lower portion of the washer body and having a bottom panel spaced from the floor panel and outer sidewalls, and which is configured to receive cleaning fluid from the wash basin through the drain aperture when the floor panel is in a substantially horizontal orientation. The portable parts washer further includes a storage reservoir formed within the upper and lower portions and which is configured to contain the cleaning fluid from the in-use reservoir when the floor panel is rotated to a substantially vertical orientation.

A paint removal apparatus for cleaning paint from masking devices includes a support base having a plurality of engagement features that are each configured to securely engage at least one paint masking device. A spray nozzle is aimed in a fixed direction toward the support base and configured for spraying a pressurized stream of water at a desired velocity that removes paint from an exterior surface of at least one of the masking devices engaged at the support base. The support base is configured to successively move the masking devices engaged at the engagement features into the pressurized stream of water, such as to provide a generally continuous cleaning operation of masking devices. During movement or rotation of the support base, an exposed portion of the support base may extend from a spray enclosure for removing cleaned plugs from and loading painted plugs onto such an exposed portion.

A construction site tool cleaning system. A construction sink is supported by support legs. A drip pant is preferably positioned under the support legs and under the construction sink. Construction sink stabilizers are connected to the support legs and support the construction sink. A construction sink tool support screen covers the top of the construction sink. An elevated pump section is inside the construction sink and is at a higher level than the bottom of the construction sink. A water pump is positioned inside the elevated pump section. A filter screen and filter are positioned on top of the elevated pump section and surround the water pump. A flexible hose is connected to the water pump and a nozzle is connected to the flexible hose.

A non-welded field joint for connecting two portions of a pot and pan washing machine together as a single unit is provided.

The invention provides, in one embodiment, a portable wash basin assembly for cleaning a tool. The portable wash basin assembly includes a wash basin having a base and at least one sidewall that extends upward from the base to an upper edge, and a plurality of recesses located at the upper edge of the wash basin. The wash basin is configured to support the tool in a first orientation in which a first portion of the tool can be supported within one of the recesses and a second portion of the tool can be supported upon the base, and a second orientation, in which the tool can be supported within two of the recesses on the wash basin.

A safety closure for or on a container with a media supply line is described. The safety closure comprises: a lid which is actuated in particular mechanically for closing the container; a shut-off device for shutting off the media supply line; a pivoting lever with an actuating arm for pressing on the lid and with an in particular opposite first locking element; and a second locking element which is drive-coupled to the shut-off device and, which as a stop for the first locking element, being selectively operative when the shut-off device is open, is configured such that the lid can not be opened. Accidentally opening the lid when the container is spray rinsed can thereby be prevented in a simple and reliable manner.
