The present invention is a nozzle assembly having a nozzle main body including an ejection material suction port and an ejection port which ejects the ejection material with the compressed air, and an air nozzle which jets the compressed air into the nozzle main body. The nozzle main body includes a mixing chamber which mixes the ejection material with the compressed air, a first pathway directed from the ejection material suction port toward the mixing chamber, and a second pathway directed from the mixing chamber toward the ejection port. The air nozzle includes a compressed air jet portion and a third pathway directed to the compressed air jet portion, and the third pathway is inserted into the nozzle main body. The compressed air jet portion of the air nozzle is provided with a flow contracting portion having an opening.

A base for a powder coating booth, including a base structure, through which the booth is intended to rest on a floor, the base structure being configured to support a powder coating compartment of the booth. The base also includes a floor, which is supported by the base structure and which is configured to delimit the bottom of the powder coating compartment. To reduce the accumulation of residual powder, the floor includes at least one oblique panel, which is inclined with respect to the horizontal and which is configured to delimit the bottom of the powder coating compartment of the booth, whereas the at least one oblique panel is porous so as to be permeable to the air and impermeable to the residual powder resulting from powder coating an article within the powder coating compartment.

A feed center for powder coating material includes a hopper, an extraction duct, and a control valve. The hopper is connectable in fluid communication with a fluidizing pressure source. The extraction duct is connectable in fluid communication with at least one suction source. The control valve connects the extraction duct with an extraction port of the hopper. The control valve is operable between a first position for applying suction from the at least one suction source to the hopper, and a second position providing an exterior opening in at least one of the control valve and the first extraction duct for exhausting pressurized fluid from the hopper and/or collecting at least some of the air and powder that is exhausted from the powder.

The invention relates to a powder spray coating booth (1) in which objects can be coated with powder with the aid of at least one spray device (6), wherein the powder spray coating booth (1) has an exhaust channel arrangement for exhausting air and excess powder from the booth interior of the powder spray coating booth (1), and wherein the exhaust channel arrangement has an exhaust channel (9) which is arranged in the booth substructure and which is fluidically connected to the booth interior via at least one exhaust opening (8). In order to achieve that a change of powder can also be quickly carried out, the invention provides that the exhaust channel (9) is additionally fluidically connected or can be additionally fluidically connected to at least two channel sections (31, 32) which are led out of the booth substructure, via a manifold (30) arranged in the booth substructure.

Powder is sprayed uniformly and favorably from a powder nozzle into processing target air. In a coating mist collection apparatus, coating mist in processing target gas is collected by filters in a state in which a coating mist trapping filter covering layer made up of an accumulated layer of powder is formed on the surface of the filters. The coating mist collection apparatus is provided with a powder dispersion means that obtains a uniform powder concentration in the air in sealed powder tanks by dispersing the powder stored in the tanks in a uniform floating dispersed state, and is provided with a spray air conveying means that supplies the powder in the floating dispersed state in the powder tanks along with carrier air to powder nozzles through powder supply passages.

The assembly (1) for coating workpieces (32) comprises a treatment chamber (1) with a manipulator (24) arranged therein. The manipulator (24) carries a coating device (25) for coating the workpieces (32). The treatment chamber (1) configured as a tank (1) is topped by an exhaust port (3) for exhausting hot gases and/or coating particles. In the interior of the treatment chamber (1) an exhaust hood (33) for channelizing the gases to be exhausted in the direction of the exhaust port (3) is arranged. The exhaust hood (33) together with the pallet (29) are arranged on a shiftable platform (16). The platform (16) together with the exhaust hood (33) and the pallet (29) can be retracted in and extended from the treatment chamber (1). The exhaust hood (33) is arranged on the platform (16) such that when the platform (16) is positioned retracted the exhaust hood is connected to the exhaust port (3).

The present invention generally relates to an electrostatic coating system for spraying a stream of particles onto a medium, and in particular to a system comprising one or more apparatuses equipped with a powder coating suspension device. What is also contemplated is the use of a powder management system configured to supply predetermined powdered and air mixtures to the apparatus and a controller configured to adjust parameters of operation of both the apparatus and the powder management system. The present disclosure relates to an in-line industrial device able to coat paint, starch, thermoplastic materials, or any other powder material onto a medium by successively controlling a plurality of parameters.

A robotic system is provided for repeatedly and reproducibly applying a sealant to a seam in an assembled HVAC (Heating, Ventilation, and Air Conditioning) duct component. The applied sealant has a predetermined location on the assembled HVAC duct component to seal the seam. An assembled HVAC duct component is thus provided having a robot applied sealant on at least one seam in the assembled HVAC duct component, wherein the applied sealant has at least one of a predetermined location, thickness or coverage. The robotically applied sealant can be applied to a blank for forming the assembled HVAC duct component, wherein the sealant is located at locations forming a seam in the assembled HVAC duct component.
