ABSTRACT:
Device for dewatering and drying solids, especially plastics granulated under water, in form of a centrifuge dryer comprising a housing (1) having an inlet opening (2) for the solid material with adhering water and an outlet opening (3) for the dehydrated solid material, a screen cylinder (4) fixedly disposed inside the housing (1), a rotor (5) arranged inside the screen cylinder (4) and wings (6) attached to the rotor at a distance from one another, a water drain (7), and arrangements (8, 8′) for the introduction and removal of an air stream passing vertically through the device. It is distinguished on the one hand in that the inlet opening (2) is arranged tangential to the screen cylinder (4, 10). On the other hand it is distinguished in that the fixed screen cylinder (4) is comprised of at least three screen cylinders (10, 11, 12) arranged vertically one over another, each of the screen cylinders (10, 11, 12) is being comprised of at least two segment shells (10, 10′, 11, 11′, 12, 12′) where the lowermost screen cylinder (10) is comprised of a screen-like shell (10′) and a solid segment shell (10″).
