ABSTRACT:
A high consistency pulp slurry is prevented from floccing by at least one pivotable member located in the vat at the area where the pulp slurry leaves the inlet box and enters the vat. The pivotable member is located with respect to the inner surface of the vat and is structured to speed-up the pulp slurry as it enters the vat to prevent floc formations.
If pulp fibers should become stuck in the small space between the outer surface of the pivotable member and the inner surface of the vat, the pivotable member will automatically pivot away from the inner surface of the vat, thereby automatically loosening the stuck fibers. As soon as the stuck fibers are loosened, the pivotable member will return to its initial position.
