<p>Apparatus and a method for dewatering a bead suspension of fragile beads having a high water content suspended in a liquid include a staging vat (12), a metering vat (16), and a dewatering vat (20). The application of pressurized gas to the staging vat (12) causes the bead suspension to move up a central feed tube (14) which extends from the staging vat to the metering vat. The bead suspension is gravity fed from the metering vat through a transfer pipe (18) and into the dewatering vat. The bottom portion of the dewatering vat has both an inner wall and an outer wall wherein the upper portion of the inner wall has perforations and the bottom portion is solid. Upon entering the dewatering vat, the bead suspension pours a short distance onto an inverted spreader cone. The bead suspension flows down the spreader cone and pours over the edge of the cone toward the perforated upper portion of the inner wall. The liquid flows through the perforations of the upper inner wall to the outer wall, and the dewatered beads are deflected toward the apex of the conical solid bottom portion of the vat for further processing.</p> |
