    摘要： The invention relates to a method for sealing a filter chamber of a filter device, the filter device having a pack of at least a recess plate (15) and an adjacent recess plate (15), the recess plate (15) having a first recess (22) and/or the adjacent recess plate (15) having a second recess, the first recess (22) and/or the second recess forming the filter chamber between the recess plate (15) and the adjacent recess plate (15), the recess plate (15) having a groove (25) encircling the filter chamber, and a sealing ring (24) inserted into the groove (25), the sealing ring (24) sealing the filter chamber from a gap between the recess plate (15) and the adjacent recess plate (15), the method comprising a sequence of steps, including moving the recess plate (15) close to the adjacent recess plate (15) for building the pack, and securing the recess plate (15) to the adjacent recess plate (15), piping a suspension into the filter chamber on a cake side of a filter cloth, letting a solid content of the suspension settle on the filter cloth as a filter cake, and a liquid fraction of the suspension permeate the filter cloth to a filtrate side thereof, and discharging the filtrate out of the filter chamber. The invention further relates to a recess plate (15) for use in a filter device, the recess plate (15) comprising a recess, and a groove (25) encircling the recess, the groove (25) being adapted to receive a sealing ring (24) for sealing a filter chamber formed by the recess between the recess plate (15) and an adjacent plate from a gap formed between said plates outside the filter chamber. In order to reduce delivery of suspension into the gap between the recess plates (15), according to the invention it is suggested to move the recess plate (15) and the adjacent recess plates (15) into contact, and then to force the sealing ring (24) out of the groove (25) towards the adjacent recess plate (15). Further according to the invention it is suggested to provide a fluid channel extending from the head piece to the recess plate (15), and a fluid duct (30) connecting to the groove (25) for feeding a forcing fluid into the groove (25). Further according to the invention it is suggested to provide a fluid duct (30) adapted to communicate with a fluid channel extending from a head piece of the filter device to the recess plate, and to feed a forcing fluid into the groove (25).

    摘要： A grouping vibration device for filter plates (4) of a press filter used for pulling the filter plates (4) of the press filter in groups to discharge the filter cake, which vibrates a vibration rod (11) by the use of a cylinder assembly (6) to vibrate the filter cloth bracket rod (27), thereby discharging the filter cake. After the first group of filter plates (4) is pulled, a movable frame is transmitted by a driven gear (8) of a retarding braking motor (9) to the vibrating location. Then a gas source bypass valve (19) is opened to make the cylinder to hammer the vibration rod (11) by a gas source three-joint workpiece (13). The vibration times of the cylinder are controlled. After the vibration, the vibration rod (11) is automatically retracted by a sleeve spring device (5) and the filter cloth bracket rod (27) is vibrated by the vibration rod (11) to discharge the filter cake automatically. After the vibration of the first group, the second group of filter plates (4) begins to be pulled. After the grouping vibration of the filter plates (4) is completed successively, a position limiter disposed at the ultimate end makes the movable frame back to the original position. The course of the vibration procedure is controlled by a PLC program. The programmable control of the vibration times, travel distance, etc. is achieved.
