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.
摘要翻译：从喷雾室抽出的粉末过喷被回收到用于向喷雾室内的喷枪供应粉末的粉末供应。从展位提取的粉末过度喷雾通过诸如旋风分离器之类的分离器与高流量空气流分离。粉末落入转盘中，使用真空将粉末从转盘传送到真空接收器。然后将粉末排出到进料中心的进料斗。使用真空将粉末从旋风分离器输送到进料中心实际上允许基本上所有的粉末过度喷雾在喷雾室中直接回送到进料斗，在旋风分离器或真空接收器子系统内以最小的停留时间或停留时间喷涂操作。接收器可以旋转以便于清洁，并且真空线被一个或多个清洁元件清洁通过真空管线拉出。

摘要： Method and apparatus for cleaning a powder transfer duct uses a pressurized volume of air directed at an interior surface of the duct to dislodge powder particles adhering to the interior surfaces or that are entrapped within a volume or region of the duct interior. In one embodiment of the invention, the duct is a passageway for powder that is entrained in an air stream from a powder spray booth to a powder collection device such as, for example, a cyclone separator. Pressurized air is provided by a device that can be selectively activated to direct a blast of high pressure air into the duct interior in a direction that is generally transverse a primary air flow through the duct. The device may be realized in the form of a pulse valve that has an outlet that opens to the duct interior and directs a pulse of pressurized air at a surface or region within the duct where powder tends to accumulate, either from eddy current characteristics or from impacting the interior surface. The pulse valve may be mounted to a wall of the duct. Pressurized air is supplied to the pulse valve from an accumulator connected thereto. The pulse valve may be manually actuated or actuated by other suitable control mechanisms. In accordance with another aspect of the invention the device is activated while air is flowing through the duct, such as when the separator is operating.
摘要翻译：用于清洁粉末输送管道的方法和设备使用指向管道内表面的加压体积的空气来移除附着在内表面上的粉末颗粒或被截留在管道内部的体积或区域内。在本发明的一个实施例中，管道是用于粉末的通道，其被夹带在从粉末喷雾室到粉末收集装置（例如旋风分离器）的空气流中。加压空气由可被选择性地启动的装置提供，该装置可以以大致横向通过管道的一次空气流的方向将高压空气的鼓风引导到管道内部。该装置可以以脉冲阀的形式实现，该脉冲阀具有通向管道内部的出口，并且在涡街电流特性或从涡流特性引起的粉末倾向于积聚的管道内的表面或区域处引导加压空气的脉冲影响内表面。脉冲阀可以安装在管道的壁上。加压空气从与其连接的蓄能器供应到脉冲阀。脉冲阀可以由其他合适的控制机构手动地致动或致动。根据本发明的另一方面，当空气流过管道时，例如当分离器操作时，该装置被激活。
