FEEDER FOR TRANSFERRING MATERIAL BETWEEN VESSELS HELD AT DIFFERENT PRESSURES

摘要

Revolver-type transfer device for bulk material with a new type of a sealingsystem. The transfer device comprises a rotatable shaft (6) with a rotor (3)having a plurality of axial flow channels (4,5); and a casing (1) enclosingthe rotor. Axially movable sealing plates (11,12) are provided between theends of the rotor and the ends of the casing and means for pressurizing thechamber (2) by feeding a pressurized fluid (L1) to the casing. The devicecomprises connections (13,14,15,16) for low-pressure flow into and out of theflow channels and for high-pressure flow into and out of the flow channels.The device can be used to transfer steamed wood chips in solution from lowpressure into a digester at high pressure.
