A powder coating system comprising a plurality of supply containers and a connection changer having a plurality of supply connectors associated with a support member and each in fluid communication with at least one of the plurality of supply containers. The connection changer includes a movable delivery connector selectively and independently connectable to each of the plurality of supply connectors associated with the support member. A pump is in fluid communication with the delivery connector of the connection changer and at least one applicator is in fluid communication with the pump. Fluid communication from the delivery connector to the applicator defines a delivery portion of the system. The pump is disposed along the delivery portion of the system to apply negative pressure to the at least one selected supply container and draw its contents to the at least one applicator.

Supply changing apparatus for powder coating systems

A powder coating system includes a booth and one or more powder-recovery modules that are insertable into an equipment-receiving space of the booth. A color change method includes removing a first powder-recovery module from the equipment-receiving space and positioning a second powder-recovery module in the equipment-receiving space.

Powder coating system and method for quick color change

A booth of a powder coating system is designed for quick color changes. The booth includes a bottom wall supported above a floor. An inner space of the booth is defined above the bottom wall and an equipment-receiving space is defined beneath the bottom wall. The bottom wall has an opening providing communication between the inner space and the equipment-receiving space. The booth is adapted to receive a powder-recovery module beneath the bottom wall in the equipment-receiving space.

Color change booth

Methods and systems for recovering paint include utilizing a plurality of centrifugal separator modules downstream of a paint booth. Each of the centrifugal separator modules includes a plurality of centrifugal separators. Each of the centrifugal separators separates at least a portion of the paint particles from an air stream.

Centrifugal separator arrangement for powder coating recovery system and methods

Apparatus for fluidizing a pulverulent material in a stream of fluidizing gas includes a membrane through which the fluidizing gas can flow but the pulverulent material cannot, a first fluidizing gas gallery on a first side of the membrane, a second fluidized pulverulent material gallery on a second side of the membrane, a passageway out of the second gallery for the removal of fluidized pulverulent material therefrom, and apparatus for generating a signal indicative of fluidizing gas pressure inside the second gallery and controlling fluidizing gas pressure in the second gallery in response to the generated signal. The passageway accommodates a conveyor having multiple conveying sections. At least a first of the multiple conveying sections is located adjacent an inlet opening of a housing for the conveyor. The first conveying section is generally coextensive with the inlet opening. A conveyor drive mechanism is selectively engageable with the conveyor.

Powder feed mechanism

A pulverulent coating material application and reclaiming system comprises a booth including a floor, a pair of opposed side walls and a pair of opposed ends. Articles to be coated are conveyed through the booth between the walls and above the floor for coating by the pulverulent material. A dispenser dispenses pulverulent material onto the articles as they are conveyed through the booth. A receptacle is provided under the floor for reclaiming pulverulent material which does not adhere to the articles. The floor terminates short of ends of the booth to define adjacent to the ends entries to the receptacle for reclaimed pulverulent material. A floor wiping mechanism includes a wiper, low friction mountings on the wiper to permit low friction movement of the wiper on the floor, scraping blades mounted on the wiper in contact with the floor, and a prime mover for reciprocating the wiper at intervals lengthwise of the floor to return pulverulent material accumulated on the floor therefrom into the entries.
