Overflow-separating centrifuge for the separation of solid-liquid suspensions

摘要

1. An overflow separation centrifuge for separating suspensions in the form of liquid-solid mixtures, in particular for the separation of slurry, into liquid and solid, comprising a drum (1) enclosed with clearance by a stationary outer casing (4) and being drivingly rotatable about a usually horizontally extending longitudinal axis (3), one end wall (1b) of the drum being in the form of a closed drum base and the other end wall (1c) having a central circular opening (5) for feeding in the suspension and for discharging the solids and an overflow edge (7) bounding the circular opening (5), characterized in that at least one end wall (1b) of the drum (1) has through openings (10) for removing residual water from the solids, the openings (10) being arranged around the periphery in the vicinity of the peripheral wall (1a) of the drum and being closable from the outside by a covering device (11; 21; 29).
