Skimmer device for discharging liquid from a centrifugal drum

A skimmer device (100) for discharging liquid from a centrifuge drum (10) comprising a vertically arranged skimmer disk pipe (20) and a skimmer disk (30) which is arranged inside the centrifuge drum and provided with at least one inlet duct. The inlet duct extends from the periphery (31) of the skimmer disk (30) and leads into at least one shaft duct (22 which extends at least partially along the skimmer disk pipe. The inlet duct (32) and the shaft duct (22) form a discharge duct which has at least one throttle point where the cross-sectional area of the discharge reduced. The inlet duct (32) is divided by at least one duct division element (33.1, 33.2) into at least two partial inlet ducts (32.1 . . . 32.3) which are arranged on top of each other and which lead into the shaft duct (22). Each partial inlet duct (32.1 . . . 32.3) is provided with at least one partial inlet duct throttle element (34.1 . . . 34.3) at said throttle point.
