Abstract

A separator insert for a separator includes a housing that is stationary during operation and is a container that is closed apart from multiple openings. These openings include a supply opening for an in-flowing suspension in a first axial boundary wall of the housing, two outlets for flowable phases of differing densities in an outer casing of the housing, and a recirculation inlet in a second axial boundary wall of the housing. A rotor within the housing can rotate about an axis of rotation and has a drum, which has multiple openings. A separator is arranged in the drum. At least two rotor units for magnetic bearing units are arranged at two axially spaced-apart points on the rotor with the drum, with which the rotor with the drum can be held in a suspended state, can be rotationally mounted and can be made to rotate within the housing during operation.

Dependent claims

A separator insert for a separator configured to separate a flowable suspension into at least a light and a heavy phase of different density in a centrifugal field, the separator insert comprising:

a) a housing, which is stationary during operation, wherein the housing is a container that is closed except for
a supply opening in a first axial boundary wall of the housing and configured to receive an inflowing suspension;
two outlets in an outer casing of the housing and configured to output the light and heavy phases;
and
a recirculation inlet in a second axial boundary wall of the housing;
b) a rotor, which is rotatable about an axis of rotation, arranged within the housing, wherein the rotor comprises a drum, which has multiple openings comprising
at least one first opening and at least one second opening are configured as free radial outlets for the light and the heavy phase into the housing;
two further openings at two axial ends of the drum;
an upper feed pipe extending into an upper one of the two further openings and a lower feed pipe extending into a lower one of the two further openings, wherein the upper and lower feed pipes do not touch the drum, and wherein one of the upper and lower feed pipes is fluidically coupled to one of the two outlets;
c) separating means arranged in the drum;
and
d) at least two rotor units arranged at two axially spaced-apart points on the rotor, wherein the at least two rotor units are respectively part of a corresponding magnetic bearing device, and wherein the at least two rotor units are configured to hold the rotor in a suspended state, to rotatably mount the rotor, and to rotate the rotor within the housing during operation of the separator, and
wherein the upper feed pipe passes axially through an upper one of the at least two rotor units and the lower feed pipe passes axially through a lower one of the at least two rotor units.

a supply opening in a first axial boundary wall of the housing and configured to receive an inflowing suspension;
two outlets in an outer casing of the housing and configured to output the light and heavy phases;
and
a recirculation inlet in a second axial boundary wall of the housing;
b) a rotor, which is rotatable about an axis of rotation, arranged within the housing, wherein the rotor comprises a drum, which has multiple openings comprising

and
two further openings at two axial ends of the drum;
an upper feed pipe extending into an upper one of the two further openings and a lower feed pipe extending into a lower one of the two further openings, wherein the upper and lower feed pipes do not touch the drum, and wherein one of the upper and lower feed pipes is fluidically coupled to one of the two outlets;
c) separating means arranged in the drum;
and
d) at least two rotor units arranged at two axially spaced-apart points on the rotor, wherein the at least two rotor units are respectively part of a corresponding magnetic bearing device, and wherein the at least two rotor units are configured to hold the rotor in a suspended state, to rotatably mount the rotor, and to rotate the rotor within the housing during operation of the separator, and
wherein the upper feed pipe passes axially through an upper one of the at least two rotor units and the lower feed pipe passes axially through a lower one of the at least two rotor units.
