Abstract
A particulate solids conveying and draining device, for mounting in a solids outlet wall, comprising a funnel-shaped rotor with particulate solids scooping members attached thereto. Each particulate solids scooping member comprises a paddle scooping portion leading to a liquid draining, particulate solids spilling, rib portion. In operation, the rotor is rotated so that the particulate solids scooping members scoop a slurry of the particulate solids and, on rotation, drain liquid therefrom through liquid return ports to the center of the funnel-shaped rotor and back to the slurry. When particulate material reaches its angle of repose on a particulate solids scooping member, it tumbles across and off the rotor on the other side of the outlet wall to that at which the slurry is situated.
