<p>Solids Flow Control Device Thomas Henry Milliken 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.</p> |
