  • Bag filter for cleaning dust-laden gases
    Patent number: 4067708
    Abstract: A bag filter for cleaning dust-laden gases comprises rows of vertically extending bags accommodated in a casing. Open lower ends of the bags are fixed to and communicate with a hopper which is separated from the inner space of the casing. Upper ends of the bags are closed by caps supporting vertical rods connected to a mechanism for removing dust from the bag cloth. The mechanism comprises pulleys fixed to the rods and two flexible drawbars having their ends secured to each pulley so that they run therefrom in opposite directions. Other ends of the flexible drawbars are secured to horizontal bars extending along the pulleys and having a drive for causing their longitudinal reciprocations for rotating the caps and twisting the bags to break up dust layers on the filtering cloth.
