Abstract (en)
[origin: US5800876A] A method and a device for controlling the outflow of fluid powder from a container can be used for controlling the expulsion of powder out of a powder-spraying apparatus for electrostatic coating. The disadvantages of a mechanical closing device are avoided by introducing closing air into an extraction pipe for extracting fluidized powder out of a container. The closing air is introduced through a pipe which opens into an orifice in the casing of the extraction pipe. The mass flow of fluidized powder can be controlled by an appropriate setting of a pressure in the extraction pipe in relation to the pressure in the fluid bed, that is to say by the introduction of closing air at an appropriate pressure.
