Abstract
The invention relates to an outlet device (10) of a solid-bowl screw centrifuge for separating a multi-phase material, which outlet device is arranged on an end wall (12) of a centrifuge drum, which rotates about a longitudinal axis, at an outlet opening (20) formed in the end wall, which outlet device comprises a diverting channel (22) for diverting a liquid phase of the material which passes through the outlet opening (20), wherein the diversion relative to the longitudinal axis amounts to an angle (32) between 50° and 90° with respect to the circumferential direction, and which outlet device has an aligned rectilinear weir edge (30) for limiting the emergence of the liquid phase, wherein the angle of the alignment of the weir edge (30) relative to the end wall (12) as viewed from the outlet opening (20) amounts to between 0° relative to the end wall and minus 6° toward the end wall.
