Abstract

A separator with a rotating system includes a drum with a vertical axis of rotation, which drum is rotatable during operation, and a drum inner chamber subdivided into a lower double-conical centrifuging chamber and an upper double-conical centrifuging chamber. Both centrifuging chambers have solids discharge openings that are openable and closable in the lower centrifuging chamber by a piston slide and in the upper centrifuging chamber by an auxiliary slide. The mass moment of inertia J Q of the rotating system about a transverse axis Q extending through the center of gravity S of the rotating system of the drum and which is perpendicular to the vertical axis of rotation D is greater than the mass moment of inertia J D of the rotating system about the vertical axis of rotation D of the rotating system.

First claim

The invention claimed is:

1. A separator, comprising:
a rotating system, which comprises a drum with a vertical axis of rotation, wherein the drum is rotatable during operation and has a drum inner chamber, which is subdivided into a lower double-conical centrifuging chamber and an upper double-conical centrifuging chamber,
wherein the lower and upper double-conical centrifuging chambers each have solids discharge openings, which are openable and closable in the lower centrifuging chamber by a piston slide and in the upper centrifuging chamber by an auxiliary slide,
wherein a mass moment of inertia of the rotating system about a transverse axis extending through a center of gravity of the rotating system of the drum and which is perpendicular to the vertical axis of rotation is greater than a mass moment of inertia of the rotating system about the vertical axis of rotation of the rotating system,
wherein the drum inner chamber is subdivided by a conical partitioning plate into the lower double-conical centrifuging chamber and the upper double-conical centrifuging chamber, and
wherein the auxiliary slide has a double-conical form, and a sealing ring is formed between the conical partitioning plate and the auxiliary slide.

2. The separator of claim 1 , wherein the conical partitioning plate has a distribution duct for conducting clarified product into the upper centrifuging chamber from the lower centrifuging chamber.

3. The separator of claim 1 , wherein the conical partitioning plate bears against an outer circumference of the auxiliary slide directly and/or indirectly via a sealing ring, and the conical partitioning plate extends radially inward up to a distributor.

4. The separator of claim 1 , wherein the conical partitioning plate extends radially inward up to a distributor.

5. The separator of claim 1 , wherein, in a region of the lower centrifuging chamber, the drum is configured as a clarifier for clarifying a flowable product of solids, and, in a region of the upper centrifuging chamber, the drum is configured as a clarifier, or as a combined clarifier and separator both for clarifying a flowable product of solids and for separating the product into liquid phases of different density.

6. The separator of claim 1 , wherein the drum has two centrifugal clarifiers which are connected in series.

7. The separator of claim 1 , wherein a lower separating plate assembly is formed in the lower centrifuging chamber and an upper separating plate assembly is formed in the upper centrifuging chamber, wherein the lower and upper separating plate assemblies each have one or more rising ducts.

8. The separator of claim 7 , wherein all the rising ducts of the lower separating plate assembly are situated at a different radius than all the rising ducts of the upper separating plate assembly.

9. The separator of claim 1 , wherein the drum has a drum lower part, a drum middle part, and a drum upper part or a drum cover, which are arranged vertically one above the other.

10. The separator of claim 9 , wherein the drum upper part is conical at least in sections, the drum middle part is an externally and internally cylindrical ring segment, and the drum lower part is conical at least internally in sections.

11. The separator of claim 9 , wherein the drum cover has a drum covering closing off the rotating system in a vertically upward direction.

12. The separator of claim 1 , wherein the sealing ring bears directly against the auxiliary slide in a region of a smallest inner diameter of the auxiliary slide.
