Spray device having a parabolic flow surface

Номер: US20140091156A1
Автор: David M. Seitz, Roger T. Cedoz
Принадлежит: Finishing Brands Holdings Inc

A rotary atomizer spray coating device, in certain embodiments, has a bell cup with a generally parabolic flow surface. This generally parabolic flow surface provides additional surface area for dehydration of coating fluids, thereby improving color matching as compared to traditional bell cups, for example, by affording capability for higher wet solids content. In addition, the coating fluid accelerates along the generally parabolic flow surface, resulting in the fluid leaving the bell cup at a greater velocity than in traditional bell cups. Furthermore, a splash plate disposed adjacent the bell cup, in certain embodiments, is designed such that fluid accelerates through an annular area between the splash plate and the generally parabolic flow surface. This acceleration may substantially reduce or eliminate low-pressure cavities in which fluid and/or particulate matter may be trapped, resulting in an even application of coating fluid and more effective cleaning of the bell cup as compared with traditional bell cups.
