<p>A cylinder type paper pulp washer or thickener apparatus includes a rotatable cylinder mold (12) with a forming wire surface (16). The mold (12) rotates at least partially submerged in a vat (10) of dilute paper pulp stock and a differential pressure across the wire surface draws stock from the vat through the cylinder mold (12) and forms a pulp mat on the wire surface (16), and a plurality of disrupters (60) are positioned within the vat (10) and in arcuately spaced relation to the wire surface (16) to cause a disruption of the fiber mat which obstructs the flow of the stock liquid through the wire surface (16) and thereby provides for the reestablishment of flow. Various disrupters are shown, including a rotating non-circular bar, a doctor blade, a foil, a fluid jet, a brush, a triangular protuberance. A plurality of such disrupters (60) are positioned in peripherally spaced relation to cause repeated disruption and reformation of a fiber mat to increase the throughflow and washing or thickening efficiency of the apparatus.</p> |
