  • Filter cloth suspension device for a filter press
    Patent number: 4397744
    Abstract: The upper ends of filter cloths attached to two adjacent filter plates are connected to a filter medium hanger suspended from suspension arms pivotally mounted on one of the filter plates in the upper regions on opposite sides thereof. Arm rests for supporting the suspension arms are provided on the other filter plate in the upper regions on opposite sides thereof. When the filter plates are moved from their closed state for filtration to their opened state upon completion of filtration, the suspension arms, tilting as supported by the arm rests, are caused to vibrate, thereby accelerating the stripping of the cake which has accumulated on the filter cloths connected to the filter medium hanger.
