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： 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： 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 for lengthy parts includes a booth wall structure comprised primarily of doors. A moveable roof may be raised and lowered to clean powder overspray from the interior surfaces of the booth. A cleaning process may be performed with a sideways extraction mode and a downward extraction mode. The mode change occurs when a bulkhead that travels with the moveable roof blocks the inlet duct to the recovery system. The recovery system may be a cyclone system for example. The doors of the booth are hinged so that they can be positioned for spraying operations and cleaning operations. Live hinge designs are provided and hose stress relief designs are also provided. The roof may carry accumulators for pressurized air that feed cleaning nozzles as the roof descends. In addition, exhaust air may be used to assist cleaning the interior surfaces as the roof descends. All of the energy provided for cleaning and color change may be provided by accumulators.

摘要： A powder feed hopper includes a housing which mounts a porous plate adapted to support particulate powder material and receive an upwardly directed flow of fluidizing air to form an air-entrained fluidized bed in the housing above the porous plate. In order to improve fluidization, a baffle plate is mounted beneath the porous plate in the path of the pressurized air discharged from one or more air nozzles to create a circulating flow of air-entrained particulate powder material within the fluidized bed in which the flow moves upwardly along the wall of the housing and then inwardly and downwardly toward the center of the porous plate. Additionally, stirrer blades are located immediately above the porous plate to create turbulence and reduce the formation of concentrated channels of air atop the porous plate.

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.
