Abstract
The invention relates to a device for generating a homogeneous powder-air mixture comprising a pressure section and a suction section, wherein the two sections merge in an outlet, wherein the pressure section terminates in an orthogonal direction in the suction section in an ejector-like manner, the suction section being open towards the surroundings. The invention also relates to a method for generating a homogeneous powder-air mixture.
Claims11
A device for generating a homogeneous powder-air mixture, the device comprising:
- an intake region for powder, said intake region surrounded by pressurized air forming an enveloping jet;
- a pressure section adjacent to and downstream of said intake region, said pressure section extending in an axial direction;
- a suction section, extending in a radial direction and having openings communicating with surroundings of the device, wherein said pressure section feeds into said suction section in an orthogonal direction, with said suction section completely surrounding said pressure section;
- and
- an outlet region disposed immediately downstream of said suction section.
