<p>CONTINUOUS PROCESS DIFFUSER An assembly for treating pulp and the like in a vessel by directing an axial flow of bleaching or washing liquid or the like through the pulp, and immediately thereafter removing the spent liquid from the pulp by a straining assembly. The straining assembly includes a plurality of concentric ringlike screens having radially spaced perforated or slotted side plates, a plurality of concentric ring-like headers corresponding in number to the screens and connected to the screens in end-to-end fluid communicating relationship, and a plurality of radially extending axially reciprocal arms. Liquid passing through the screens flows through the headers and through the arms out of the vessel under the influence of pressure differential. The headers are connected to the arms and the arms are connected to the headers by structures which provide bending and torsional rigidity of the straining assembly, and which minimize the adverse effects of non-synchronous operation of actuators for axially moving the straining assembly. Uniformity of pulp treatment is maximized by provision of the headers.</p> |
