Efficient filter-bag dust separation device

The invention relates to a high efficient filter bag dust separation device which has high efficient dust removal effect with low energy consumption. The device comprises a case, a blower, a filter bag frame, a flat cloth bag filtering device, a dust cleaning mechanism, a dust collecting draw. In the flat cloth bag filtering device, a plurality of flat cloth bags which form the flat cloth bag collection are internally provided with flat cloth bag separating plates, the double faces of which take concavo-convex structure. The dust cleaning mechanism is composed of an eccentric vibratory mechanism, a connection rod, a socket connecting piece, a connecting piece, a connecting plate and a threaded rod. The end surface of the eccentric vibratory mechanism is connected with one end of the connection rod; the other end of the connection rod is connected with the socket connecting piece; the connecting plate is connected with the socket connecting piece by the connecting piece; the threaded rod is screwed on the connecting rod and is connected with the connecting plate in a revolving way; the rectangle frame of the filter bag frame is composed of a left rack, a right rack, a front rack and a rear rack; wherein, the lower end surfaces of the left rack and the right rack are respectively provided with a groove profile guide way and the notches of the two groove profile guide way are opposite.
