Nishiyama, S

A powdery dust separating apparatus in a dust collector to separate powdery dust from clean gas by sucking gas containing the powdery dust into the body of the apparatus and passing this through filter members, the body being divided into a filter chamber provided with a plurality of flat box-like filter members therein, and a gas chamber to discharge the filtered gas, the gas chamber being subdivided longitudinally into gas passages with outlets to discharge filtered gas therefrom. Structure is provided to close the outlets just before the introduction of compressed air against the filter members, and at the same time introduce atmospheric air by opening atmospheric air inlets, and causing this atmospheric air to promote action as an expansion gas in addition to the compressed air, whereby the filter members are expanded rapidly and vibrated slightly so as to separate powdery dust built up on the filter members efficiently.
