ABSTRACT:
Disclosed herein is a solids flow control device for controlling the rate of flow and the distribution of flow of solids in a continuous counter current contact between liquid and solid material, and more particularly to apparatus wherein an upwardly directed liquid flow counter currently contacts a solid material, and the downward movement of solids is maintained at a uniform rate across the horizontal cross section of the vessel. The device comprises a vessel in which solids move downwardly in a liquid-solid counter current system to a control mechanism in the form of a plurality of longitudinally parallel rotating rolls and baffles which occupy the entire horizontal cross section of the vessel and maintain the even downward movement of the solids at a uniform rate across the horizontal cross section of the vessel.
