PULP THICKENING UTILIZING STATIONARY SCREENS ABSTRACT Thickening of paper pulp, or a like suspension, is effected prior to feeding the pulp to an apparatus utilizing stationary screens for effecting washing, bleaching, or further thickening of the pulp. The stationary screens are mounted in a top portion of a vertical-axis vessel, and a plurality of radially extending rotating hollow arms, with annular screens mounted on them, is provided in the bottom of the vessel to effect thickening of the suspension from, for example, 1-1/2% consistency to about 9-14% consistency. Extraction from the hollow arms is provided through conduits extending vertically through a hollow shaft for rotating the arms, and a filtrate valve is also mounted within the hollow shaft in operative communication with the filtrate conduits, and includes a valve member which is rotatable in a different direction, and at a different speed, than the hollow shaft.
