Abstract
A separator includes a housing that is stationary during operation and designed as a tank having at least two openings. A drum located inside the housing can be rotated about an axis of rotation, the drum having an axis of rotation and at least one opening. A gap is formed at least in sections or continuously between the drum and the housing. The separator also includes a support and drive device having at least two support and/or drive units, which keep the drum suspended inside the housing, supported, and/or set in rotation. One of the support and/or drive units is a first magnetic bearing that at least axially supports the drum and to keep it suspended. At least one other of the support and/or drive units is axially supports the drum.
Claims23
A separator for separating a flowable suspension in a centrifugal field into at least two flowable phases of different density, the separator comprising:
- a) a housing, which is stationary in operation and is a container having at least two openings;
- b) a drum arranged within the housing, having an axis of rotation, being rotatable about the axis of rotation, and having at least one opening;
- c) a gap formed at least in sections or continuously between the drum and the housing;
- d) a support and drive device comprising at least two support or drive units, which suspend, support, or rotate the drum within the housing;
- e) wherein a first one of the at least two support or drive units comprises a magnetic bearing, which axially supports and levitates the drum,
- f) wherein at least one further of the at least two support or drive units axially supports the drum,
- wherein the at least two support or drive units are arranged axially offset from one another in a direction of the axis of rotation, and in a first vertical alignment of the axis of rotation a lower or an upper one of the at least two support or drive units supports the drum axially and keeps the drum suspended,
- wherein a first one of the at least two support or drive units is a first combined bearing device which, in addition to an axial bearing, also effects a radial bearing of the drum,
- wherein a second or further of the at least two support or drive units is a second combined bearing device which, in addition to an axial bearing, also effects a radial bearing of the drum, and
- wherein the first or second combined bearing devices has a bearing acting obliquely to the axis of rotation.
A separator for separating a flowable suspension in a centrifugal field into at least two flowable phases of different density, the separator comprising:
- a) a housing, which is stationary in operation and is a container having at least two openings;
- b) a drum arranged within the housing, having an axis of rotation, being rotatable about the axis of rotation, and having at least one opening;
- c) a gap formed at least in sections or continuously between the drum and the housing;
- d) a support and drive device comprising at least two support or drive units, which suspend, support, or rotate the drum within the housing;
- e) wherein a first one of the at least two support or drive units comprises a magnetic bearing, which axially supports and levitates the drum,
- f) wherein at least one further of the at least two support or drive units axially supports the drum, and
- wherein the housing has two outlets that are radially aligned, wherein both of the two outlets are formed at the upper axial region of the drum at a first vertical alignment of the axis of rotation.
