FILTER BAG FOR DUST COLLECTOR OBTAINING DUST SEPARATION EFFECT

摘要

PURPOSE: A filter bag for dust collector is provided which obtains dust separation effect due to pulse jet by forming the filter bag in such a shape that mountains and valleys are formed in a longitudinal direction of the filter bag, and in which ring shaped reinforcing bands are installed in a certain distance to maintain shape. CONSTITUTION: In a filter bag for dust collector in which a filter cloth is cylindrically formed in such a way that one side of the filter cloth is closed while the other side of the filter cloth is insertingly connected to a filter cage by connector such as a snap ring, the filter bag for dust collector comprises a filter body(30) for folding the filter bag in a certain distance so that mountain parts(32) and valley parts(31) are formed on the filter bag; and reinforcing bands(40) for maintaining the mountain parts and the valley parts by sewing the mountain parts along the outer circumference of the filter body, wherein several reinforcing bands are installed per a certain longitudinal direction of the filter body, and wherein the mountain parts and the valley parts of the filter body are formed in hexagon or tridecagon.
