摘要： A material supply for a material application system such as a powder coating application system includes a feed hopper in the form of a duct. The duct is connectable to negative pressure during a color change process and is disconnected from the negative pressure during a spray application process. The negative pressure can be provided from a powder overspray recovery system such as an after filter blower. Dampers are provided to control air flow through the hopper duct and to allow the duct to be at ambient pressure during a supply mode of operation. The hopper duct also includes a suction interface for pumps, in the form of a siphon ring, as well as a fluidizing function. A removable sieve is provided with an optional vibration feature. Powder may be added to the duct via an access door or transfer pumps for new powder and/or reclaimed powder overspray.

摘要： A spray applicator for particulate material includes a unitary powder passageway sized to be particularly useful with dense phase material flow. An external electrode assembly is provided that is keyed to an air cap that is used to provide atomizing and pattern shaping air to the dense phase material that exits the powder passageway. In this manner a nozzle is not required. A manual and automatic version of the applicator are provided, including a pattern shaping trigger that can be used by the operator to dynamically adjust the spray pattern. An automatic gun version has the multiplier located at a mounting location to reduce bending moments of the elongated gun.

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.
