Abstract: An electrostatic powder spraying apparatus that includes a nonrotating disk-like member having an edge; the electrostatic field extends between the edge of disk and articles to be coated. A first means of the apparatus deflects powder radially outwardly into a chamber. The chamber is adjacent the first means and provides space in which tangential streams impart a spiral motion or whirling cyclone-type motion to the radially deflected powder. An apertured means is spaced from the non-rotating disk-like member. The spiral motion of entrained powder moves it outwardly along the surface of the non-rotating disk-like member and causes air to be aspirated through the aperture to mix with the powder moving radially outwardly along the surface of the disk-like member. By this means the powder is given sufficient momentum to be ejected from the edge of the disk to the vicinity of an article at a powder attracting potential where the electrostatic field forces can guide the charged powder to the article.

Abstract translation: 一种静电粉末喷涂装置，包括具有边缘的非旋转盘状构件; 静电场在盘的边缘和待涂覆的物品之间延伸。 设备的第一装置将粉末径向向外偏转到室中。 腔室与第一装置相邻并且提供空间，在该空间中，切向流向径向偏转的粉末施加螺旋运动或旋转旋风分离器运动。 多孔装置与不旋转的盘状构件间隔开。 夹带的粉末的螺旋运动使其沿着非旋转盘状部件的表面向外移动，并使空气通过孔吸入，以便与沿盘状部件的表面径向向外移动的粉末混合。 通过这种方式，粉末被给予足够的动量从粉末的边缘排出到制品的附近，其中静电场力可以将带电粉末引导到制品上。
