Patent ID: 8419607

Claim:
A centrifuge comprising: a centrifugal drum rotatable about a vertical axis of rotation, the centrifugal drum including one or more solids discharge orifices located at an area of the largest inside diameter of the drum, the solids discharge orifices including bores having discharge openings, and wherein the bores are arranged at least partially on an exterior of the centrifugal drum in a vertical direction Z at selected vertical heights along the exterior of the centrifugal drum; wherein the solids discharge orifices include orifice bodies which are inserted into the discharge orifices in a drum jacket and extend through the drum jacket from an inside to an outside of the centrifugal drum, and the orifice bodies are each configured with the bores extending from an interior of the drum in the direction of the exterior of the drum; and wherein the orifice bodies include a first bore section and the bores first extend essentially in a radial direction from the inside to the outside of the centrifugal drum, and then the first bore section changes to a second bore section oriented at an angle with respect to the first bore section, and the discharge openings located in the second bore section are each aligned at an angle with respect to the radial direction.
