Patent number: 10293347Abstract: A solid-bowl screw centrifuge is provided for the separation of multiphase material. The solid-bowl screw centrifuge has a centrifuge drum that is rotatable around an axis and the centrifuge drum has at least one outlet for discharging a phase of the material from the centrifuge drum. The outlet has a restrictor controlled by a floating body that floats on the material to adjust the outlet automatically in accordance with a liquid level of the material in the centrifuge drum, and the liquid level, in turn, is dependent on the throughput of the material. The restrictor may include a weighted body that is subjected to centrifugal force and also may include a restricting body arranged in a discharge port of the outlet. The outlet may include a deflection device for changing direction of the material flowing out to a direction that is transverse to the longitudinal axis.Type: GrantFiled: January 21, 2015Date of Patent: May 21, 2019Assignee: FLOTTWEG SEInventor: Georg Bauer
