摘要:
An apparatus for mounting and moving coating dispensers within the interior of a spray booth, and particularly the coating dispensers located above an object moving through the booth, comprises a dispenser housing having an aerodynamically shaped outer surface formed with a leading edge, a trailing edge and opposed generally curved sides. A pair of support assemblies isolated from the booth interior mount the dispenser housing in the path of a downward flow of air within the booth interior within which oversprayed coating material is entrained for collection such that the leading edge of the dispenser housing faces the top or ceiling of the spray booth and its trailing edge faces the objects moving through the booth. One or more coating dispensers are mounted at the trailing edge of the dispenser housing in a position to discharge powder coating material downwardly onto the object, such as the hood, roof and trunk of a vehicle body. Each support assembly carries one side of the dispenser housing and structure is provided on at least one of the support assemblies for moving the dispenser housing vertically, side-to-side and pivotally with respect to objects moving through the booth.
摘要:
Apparatus for mounting and moving coating dispensers within the interior of a spray booth, and particularly the coating dispensers located above an object moving through the booth. A first embodiment comprises a dispenser housing having an aerodynamically shaped outer surface formed with a leading edge, a trailing edge and opposed generally curved sides. A second embodiment includes a dispenser housing an outer surface with a convexly curved leading edge, flat side walls and a flat bottom wall. A pair of support assemblies isolated from the booth interior mount the dispenser housings within the booth interior such that the leading edge of each dispenser housing faces the top of the spray booth and the trailing edge faces the objects moving through the booth. One or more coating dispensers are mounted at the trailing edge of the dispenser housings in a position to discharge coating material downwardly onto the object. Each support assembly carries one side of a dispenser housing and structure is provided for moving the dispenser housings and dispensers vertically, and the dispenser housings side-to-side and pivotally with respect to objects moving through the booth. A collision detector is also provided to shut the system down in the event of a collision between the apparatus and an object within the booth.

An apparatus and method of dislodging particles of powder material from the exterior of cartridge filters in the powder recovery unit of a powder spray system. In the powder recovery unit, particles of powder material collect on the cartridge filters as filtered air enters the hollow interior of the cartridge filters and moves toward the open tops thereof. Periodically, the flow rate of the filtered air through a cartridge filter is reduced and a pulse of air is directed into the open top of that cartridge filter, in a direction opposite to the normal direction of movement of the filtered air, to dislodge the particles from the cartridge. In addition, the cartridge filters are vertically disposed and compression mounted in such a way that the cartridge support hardware does not obstruct the air flow through the top opening of the cartridge filter.

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.

An apparatus for applying powder coating material onto large objects such as automotive, truck or other vehicle bodies includes a powder spray booth defining a controlled area within which to apply powder coating material onto the vehicle bodies, a powder kitchen located at a remote position from the powder spray booth, and, a number of feed hoppers located proximate the booth which receive powder coating material from the powder kitchen and supply it to automatically or manually manipulated powder spray guns associated with the booth. Oversprayed powder coating material is removed from the booth interior by a powder collection and recovery system which transmits the oversprayed powder back to the powder kitchen for recirculation to the powder spray guns.

摘要:
Apparatus and methods for aligning a powder spray canopy of a powder coating booth with a fan plenum assembly so that a powder collector can be quickly aligned and simultaneously sealed to both the powder spray canopy and the fan plenum. The invention also relates to an improved filter cartridge and filter cartridge mounting assembly which allows for quick and easy mounting and dismounting of filter cartridges to the powder collector.
