Abstract
A device for removal of fine-grained or dust-like solids from a container that is to be pressurized or is pressurized, whereby the container is equipped with a double-walled discharge cone or funnel, avoids the use of porous materials, such as sintered metals or the like, while making available good conveyance properties in the transfer funnel, without restricting the grain sizes of the material, in each instance, whereby even particle-charged gas can be used for conveyance. The gas exit openings are larger than the largest particles of the solid to be removed, and the gas exit openings are provided with a pipe connector or gas feed channel that projects into the interior of the ring chamber and has at least one angle with an imaginary horizontal plane, and the gas feed channel is part of a retention device for preventing solid from trickling into the ring chamber.
