Abstract:
1. Device for removing 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 funnel, having at least one gas feed into a ring chamber formed by the double-walled funnel, whereby the funnel wall that faces the funnel interior is provided with gas exit openings, wherein the gas exit openings are larger than the largest particles of the solid to be removed, and wherein 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 wherein the gas feed channel is part of a retention device for preventing solid from trickling into the ring chamber, and wherein injection of gas into the ring chamber at a lower active floor takes place in a tangential direction that leads to an eddy-like flow in the ring chamber and to swirl up of any solid particles that might be situated there.
