Abstract
Abstract A centrifuge drum with a beveled-plate insert consists of individual plates held apart by spacing strips. The plates are mounted on a distributor foot. The bottom of the distributor foot has channels through which the liquid to be centrifuged is conducted into the separation space. There are ribs in the separation space. Between the ribs are lifting channels into which the channels in the distributor foot empty. The lifting channels are formed by the ribs and are positioned behind the spacing strips in the direction in which the drum rotates. The layout of the lifting channels prevents the liquid flowing into the plate insert from mixing with the solid particles that have been centrifuged out and are sliding out of the insert.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
74 words
In a centrifuge drum for clarifying and/or separating liquids, having a beveled-plate insert comprising individual plates held apart by spacing strips and resting on a distributor foot, the bottom of which has channels through which the liquid to be centrifuged is introduced into a separation space in which there are ribs, the improvement comprising: means forming lifting channels between the ribs and wherein the channels of the distributor foot empty into the lifting channels.
Claim 2
Dependent Claim
74 words
In a centrifuge drum for clarifying and/or separating liquids, having a beveled-plate insert comprising individual plates held apart by spacing strips and resting on a distributor foot, the bottom of which has channels through which the liquid to be centrifuged is introduced into a separation space in which there are ribs, the improvement comprising: means forming lifting channels between the ribs and wherein the channels of the distributor foot empty into the lifting channels.
Claim 3
Dependent Claim
21 words
The centrifuge drum according to claim 1, wherein the means forming the lifting channels comprises the ribs in the separation space.
Claim 4
Dependent Claim
25 words
The centrifuge drum according to claim 2, wherein the lifting channels are disposed behind the spacing strips in the sense in which the drum rotates.
Claim 5
Dependent Claim
25 words
The centrifuge drum according to claim 1, wherein the lifting channels are disposed behind the spacing strips in the sense in which the drum rotates.
Claim 6
Dependent Claim
23 words

Claim 7
Dependent Claim
36 words
The centrifuge drum according to claim 5, further comprising means forming vertical holes in the part of the distributor foot that extends beyond the outside diameter of the plate insert and merging into the lifting channels.
Claim 8
Dependent Claim
23 words
The centrifuge drum according to claim 6, wherein the channels in the distributor foot end at the outside edge of the vertical holes.
Claim 9
Dependent Claim
34 words
The centrifuge drum according to claim 5, wherein the distributor foot is configured to form an annular gap between the outside diameter of the distributor foot and the lower boundary of the separation space.
