AUTOMATIC FRAME OPENING DEVICE FOR FILTER PRESS DEHYDRATION FILTER DISK

摘要

PROBLEM TO BE SOLVED: To make it possible to extremely efficiently open the frames of many dehydration filter disks and to automate the peeling work of dehydrated cake. SOLUTION: Plural sheets of the dehydration filter disks 1 are connected by freely expandable and contractible connecting bodies M for connecting the adjacent dehydration filter disks 1 by making the each other's distances freely openable and closable. A pair of right and left frame opening cylinders X disposed in parallel with the hydraulic cylinders are freely longitudinally slidably disposed. Plural sheets of the dehydration filter disks 1 connected by the connecting bodies M are continuously opened by the frame opening cylinders X. Air pumps for blasting compressed air between the disk surfaces of the dehydration filter disks 1 after dehydration and the filter cloth are disposed to inflate the filter cloth P at the time of frame opening. Projections 2 for frame opening are projected to both right and left ends of the dehydration filter disks 1 and the flanks of sliding arms X1 of the frame opening cylinders X are freely retractably provided with detaining cylinders Z to be detained to these projections 2 for frame opening.
