1,086,746. Plate filter. SPARKLER MANUFACTURING CO. Nov. 24, 1964 [May 11 1964], No. 47770/64. Heading B1D. Means for both reciprocably moving washing conduit 50 within filter vessel 10 or opening the filter by moving tank 12 relative to the cover 14 comprises an hydraulic ram 58 activated within cylinder 60, which cylinder is attached to tank 12. Alternatively a rack and pinion arrangement may be used with the rack corresponding to cylinder 60. For opening the filter vessel 12, the ram 58 is held firm to the supporting structure 16 by a pin through holes 66 and 68, bolts 46 and lugs 48 are unlatched and the ram is operated to move cylinder 60 and thus tank 12 to the left. Hydraulic ram 58 and cylinder may alternatively be located on cover 14 or structure 16 with releasable securing means disposed between conduit 50 or ram 58 and the tank 12. Also tank 12 may be fixed to the frame 16 with cover 14 movable. Filter cake deposited on filter plates 42 is removed by sprays 86 and 88 (Fig. 4) which cut the cake in half vertically, and sprays from nozzles 76 and 78 and divergent nozzles 20 (Fig. 3) which wash the cake away as the conduit 50 reciprocates. The plates 42 may be vibrated by device 72 during washing and they may comprise parallel plates of metal filtering means suported on a frame. |
