Title: AUTOMATIC DUST SHAKING METHOD FOR BAG-TYPE DUST REMOVAL DEVICE, AND NOVEL BAG-TYPE DUST REMOVAL DEVICE
Abstract:
An automatic dust shaking method for a bag-type dust removal device, and the bag-type dust removal device. In the automatic dust shaking method, dust filtering cloth is disposed above a dust collection region (11) and an air inlet (12), and the dust filtering cloth is a filtering cloth made from a flexible plastic material. By adding the flexible plastic dust filtering cloth (2) to a body (1) of a dust collection bag, the dust shaking function is automatically implemented by means of vertical movement of the flexible plastic dust filtering cloth (2) and the natural caving effect of the flexible plastic dust filtering cloth (2), in combination of release and break of the dust-containing air flow; and accordingly breathing and filtering functions of a dust filtering portion are be recovered.
