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.
An outlet device (24) of a solid-bowl screw centrifuge for separation of multiphase material (20), the solid-bowl screw centrifuge having a centrifuge drum that is rotatable around a longitudinal axis (12), the centrifuge drum having an end face (10) with at least one end-wall opening (16), the outlet device (24) being attached in front of the end-wall opening (16) on an outer side on the end face (10) of the centrifuge drum, the outlet device having a shell-shaped housing (26) that is open toward the associated end-wall opening (16), an outlet (32) for discharging a phase of the material (20) from the centrifuge drum being located in the housing (26) radially outside from a liquid level (22) of the material (20) in the centrifuge drum and having a restrictor (38) that automatically adjusts in dependence on the liquid level (22) of the material (20) in the centrifuge drum, whereby the liquid level (22) is dependent on a throughput of the material (20), and the adjustment of the restrictor (38) is controlled by a floating body (42) that is designed to float on the material (20).
An outlet device of a solid-bowl screw centrifuge for separation of multiphase material (20), the solid-bowl screw centrifuge having a centrifuge drum that is rotatable around a longitudinal axis (12) and at least one outlet (32) for discharging a phase of the material (20) from the centrifuge drum, the outlet (32) being designed with a restrictor (38) that automatically adjusts in dependence on a liquid level (22) of the material (20) in the centrifuge drum, whereby the liquid level (22) is dependent on a throughput of the material (20), and the adjustment of the restrictor (38) is controlled by a floating body (42) that is designed to float on the material (20), wherein the adjustment of the restrictor (38) is carried out by a diaphragm arrangement (68) that is arranged around a discharge port (30) of the outlet (32).
An outlet device of a solid-bowl screw centrifuge for separation of multiphase material (20), the solid-bowl screw centrifuge having a centrifuge drum that is rotatable around a longitudinal axis (12) and at least one outlet (32) for discharging a phase of the material (20) from the centrifuge drum, the outlet (32) being designed with a restrictor (38) that automatically adjusts in dependence on a liquid level (22) of the material (20) in the centrifuge drum, whereby the liquid level (22) is dependent on a throughput of the material (20), and the adjustment of the restrictor (38) is controlled by a floating body (42) that is designed to float on the material (20), wherein the outlet (32) is designed with a deflection device for deflecting the material (20) flowing out there from a direction of the longitudinal axis (12) of the centrifuge drum into a direction that is transverse to the longitudinal axis (12).
