DUST FILTER Russian patent published in 2002 - IPC

FIELD: devices for catching dust, particularly, for cleaning of dust-laden compressed air for pneumatic transport, etc. SUBSTANCE: filter has casing, cover, inlet and outlet holes at least one filter member installed on intermediate bottom. In this case, nozzle for air blowing-through corresponds to each filter member. Space found above nozzles for air blowing-through is made in the form of pressure cavity, so that it is possible to abandon apparatuses needed until now, and control instruments. Every nozzle is directly connected to pressure cavity which is found above cavity for cleaned gas and formed by cover and bottom limiting cavity for cleaned gas from atop. EFFECT: simplified cleaning of filter members and reduced expenditures for design ensuring compressed air supply. 4 cl, 3 dwg
