GROUPING VIBRATION DEVICE FOR FILTER PLATES OF PRESS FILTER

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.
