    Abstract: Apparatus for detecting powder flow along a powder flow path includes a light source and a light detector for detecting light from the light source directed across the powder flow path as powder flows through said powder flow path. A circuit receives the output from the light detector and determines an average or RMS of the signal received by the light detector. The circuit may determine whether there is flow or no flow of powder or whether there is a change in flow rate of powder. Preferably, the apparatus is used in combination with a dense phase powder pump, which causes the powder to flow in pulses from the pump outlet into the powder flow path. More preferably, the light source and detector are enclosed in a housing that is connected between the pump outlet and a powder feed hose which supplies powder to a spray gun or hopper.

    Abstract translation: 用于检测沿着粉末流动路径的粉末流动的装置包括光源和光检测器，用于当粉末流过所述粉末流动路径时检测来自指向粉末流路的光源的光。 电路接收光检测器的输出，并确定由光检测器接收的信号的平均值或RMS。 该电路可以确定粉末是流动还是没有流动，或者粉末的流速是否有变化。 优选地，该设备与致密粉末泵组合使用，其使得粉末以脉冲形式从泵出口流入粉末流动路径。 更优选地，光源和检测器被封装在壳体中，壳体连接在泵出口和将粉末供应给喷枪或料斗的粉末供给软管之间。

    Abstract: A pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided. A pump control feature is provided for air flow rate control during positive and negative pressure conditions.

    Abstract: A particulate spray booth having a sealed particulate spray device booth wall opening is disclosed. The powder coating material spray system may include a booth comprising a ceiling, a floor, and side walls defining an interior of the booth, wherein the booth defines an opening from the interior of the booth to an exterior of the booth. The system may further include a powder spray device received through the opening, the powder spray device comprising a body and a nozzle through which powder coating material is sprayed into the interior of the booth, wherein the nozzle and at least part of the body are disposed in the interior of the booth. The system may further include a flexible boot element having a proximal end and a distal end opposite the proximal end, the proximal end attached to a periphery of the opening to form a first seal and the distal end attached to the at least part of the body of the powder spray device disposed in the interior of the booth to form a second seal.

    Abstract: A dense phase pump has two housings that are attached together using a single releasable fastener. The fastener can be released to allow the two housings to be separated thereby providing access to replaceable components. The replaceable components may include one or more pinch valves or one or more barrier elements. A pinch valve for a dense phase pump has a shape or profile for aligning the pinch valve when the pinch valve is installed in a pinch valve body. The pinch valve optionally has two end flanges, with each end flange having a shaped periphery. The two end flanges may have the same size and shape so that the pinch valve can be installed in either of two orientations that are inverse. A dense phase pump has a pump chamber that can be purged by purge gas that enters the pump off-axis from a purge path axis.

    Abstract: 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.
