Abstract
A lock chamber for discharging dust from an apparatus at an elevated pressure to a low-pressure space, e.g. from an electrostatic separator or cyclone separator at high pressure to a collector or bin at atmospheric pressure, comprises a chamber having an upper inlet and a lower outlet opening and a rotary valve member having a window and adapted, upon rotation, to selectively block and unblock the openings alternately so that pressure is maintained in the high-pressure apparatus while dust can be discharged from the chamber.
