摘要： A method and apparatus of powder coating relatively large objects such as automotive or other vehicle bodies comprises a spray booth having an interior which includes a cut-in coating zone having a relatively large area to permit the application of powder onto the interior portions of the vehicle body such as the inner door flanges, a side coating zone area wherein the vertically oriented, exterior surfaces of the vehicle body are coated such as the doors and fenders, an overhead coating zone in which the horizontally oriented, exterior surfaces of the vehicle body are coated such as the hood, roof and trunk, and, two transition zones separating the three coating zones. Air infeed and exhaust devices associated with each coating zone and each transition zone are operated to vary the air flow rate within the booth interior in the course of movement of the vehicle body therethrough such that the air velocity in each coating zone is maintained below a predetermined maximum downdraft velocity throughout the coating operation, and such that a slightly negative pressure is maintained within the booth interior.

摘要： Systems and methods for applying powder coating materials in electrostatic spray systems are provided. For example, a gravity feed of recovered powder coating from the recovery system to the feed system is disclosed. In addition, a powder feed system is disclosed wherein a powder suction lance assembly has only two operable positions, a first for feeding powder from a fluidized hopper and also corresponding to a purge position for a novel purge manifold, and a second retracted position for powder color changes and servicing. Also, a pump assembly block in physical communication with an air line attachment plate, a suction tube plate, and a hose manifold is disclosed. A plurality of attachment members removably attach the air attachment plate, a suction tube plate, and the hose manifold plate to the pump assembly block. Method for applying a first powder color and a second powder color in a powder feed center are also provided. The one method includes, among other things, the step of replacing a first pump assembly and with a second pump assembly that is in fluid communication with the one or more spray devices. The second pump assembly may be a new, previously cleaned, or color dedicated pump assembly. So configured, the present invention reduces the amount of time required for a powder color change in an electrostatic spray system and reduces color cross-contamination effects involved when changing between powder colors. Powder contacting surfaces are reduced, as well.

摘要： Powder overspray that is extracted from a spray booth is recovered back to a powder supply that is used to supply powder to the spray guns inside the spray booth. The powder overspray extracted from the booth is separated from the high flow air stream by a separator such as a cyclone separator. The powder falls into a transfer pan and a vacuum is used to convey the powder from the transfer pan to a vacuum receiver. The powder is then discharged to the feed hopper in the feed center. The use of a vacuum to convey powder from the cyclone to the feed center in effect permits substantially all of the powder overspray to be recovered from the spray booth directly to the feed hopper with minimal dwell or residence time within the cyclone or vacuum receiver subsystems during a spraying operation. The receiver can be rotated for easy cleaning, and the vacuum line cleaned by one or more cleaning elements drawn through the vacuum line.

摘要： A powder spray booth includes a booth canopy wall arrangement to contain powder during a spraying operation; and a booth floor that is rotatable relative to the booth wall during a spraying operation. The floor can be rotated about an axis that is also the longitudinal axis of the spray booth. The booth may be generally cylindrical in shape with a round floor. The booth canopy and top are supported on a base frame separately from the floor. By this arrangement, the floor can be rotated relative to the booth canopy. A powder extraction apparatus in the form of a low pressure duct suspended off the floor draws up powder that has collected on the floor. The extraction duct is stationary with respect to the rotating floor during a spraying operation. The floor may also be translated along the axis of rotation between a first position in which the floor can rotate and a second position in which the floor is sealed against a lower edge of the booth canopy wall. The booth canopy and floor are made of composite materials that are very low in conductivity to minimize powder adhering to the floor and booth walls. The booth is thus easy to clean with a substantially shorter time period required for color change.

摘要： A powder spray booth includes a floor having a longitudinal opening, preferably centered about a central longitudinal axis of the booth. Below the floor surface is an exhaust duct having a tangential entry. Powder overspray is extracted from the booth through the exhaust duct by passing through the floor opening and into the tangential entry to the exhaust duct. A suction device is used to draw powder entrained air through the exhaust duct. The tangential entry produces a swirling powder flow in the nature of a vortex within the exhaust duct to keep the powder in process and not remaining in the exhaust duct. The exhaust duct may include movable plates that form part of the exhaust duct, and also a baffle arrangement for varying the size of the opening in the floor. The exhaust duct may be, for example, cylindrically shaped. The frame that is used to support the exhaust duct may be modular in design to facilitate designing the length of a spray booth for a particular application.

摘要： A powder coating booth containment structure including first and second canopy halves, each of which is a substantially nonconductive, seamless, structural composite to substantially reduce oversprayed powder particle adhesion to the booth inner surfaces. The composite canopy halves, when assembled into a spray booth additionally including either a floor or a utility base and one or a pair of end units in the form of aperture bulkheads, vestibules, or a combination of both, are structurally sufficiently strong that no external support frame is required. The composite canopy halves can each include sidewall and ceiling portions, in an embodiment, that can be connected to a floor. In another embodiment, the canopy halves each additionally include a floor portion such that they may be connected together at a floor edge and placed atop a utility base. They may be connected to the utility base. In another embodiment, the canopy halves may each further include an integral end or ends, comprising aperture bulkhead or vestibule-type end portions. Methods of assembling these embodiments are also provided that require less time than for known powder coating spray booth assembly.

摘要： A powder spray gun includes a rotary distributor which is capable of operating at slower speeds than liquid spray gun to reduce the problem of powder fusing, increases bearing life, reduce wear on moving parts while generating larger fan patterns and optimized charge transfer capabilities. The powder spray gun has a powder flow path which extends through a gun body to a powder outlet. The rotatable powder distributor is located at the powder outlet. A drive mechanism in the form of a motor is located within the housing and connected to the distributor the rotate the distributor. A spindle, which is mounted for rotation within the body, has a passageway therethrough which forms a part of the powder flow path. The distributor communicates with the passageway and is attached for rotation with the spindle. The powder thus enters the passageway in the rotating spindle before it passes into the rotating distributor. A chamber is formed within the body around the spindle, and the chamber is connected to an air supply to pressurize the chamber. A nonrotating flow tube through which powder flows into the passageway in the spindle, with a gap being formed between the nonrotating flow tube and the rotatable spindle. The gap communicates with the chamber whereby pressurized air from the chamber escapes through the gap to provide a rotary seal between the tube and the spindle. A sealing member may be used to prevent back flow of air through the gap.
