Abstract
Apparatus for separating and displacing the plates of a filter press, one by one, is provided with a rail mounted above and extending along the length of the press on which a trolley is supported. The trolley is movable reciprocably along the rail by an endless envelope change drive, entrained with a sprocket wheel fixed on a shaft, journalled in the trolley. A separating device is supported in the trolley for movement reciprocably perpendicular to the direction of movement of the trolley toward and away from the filter plates. The separating device is connected to the sprocket shaft so that rotation of the shaft lifts or lowers a separating wedge relative to the filter plates separating the first of the filter plates and enabling the trolley to displace it alone.
