Bei den bisher bekannten Centrifugen zum Abscheiden von Schlamm, Hefe u. dgl. aus irgend einer Flüssigkeit versieht man gemä'fs Fig. 2 der Zeichnung den Trommelmantel a auf seiner inneren Umfläche mit schrägen, curven- oder winkelförmig verlaufenden Rippen oder Kanälen b, die gruppenweise in ungefähr in der Achsrichtung verlaufenden Längskanälen c zusammenlaufen, und zwar zu dem Zweck, die gegen den konischen Trommelmantel geschleuderten Schlamm- bezw. Hefetheilchen nur an jenen Stellen dem Centrifugenboden d zuzuführen, wo sich die Mündung der für die Abführung der Schlamm- bezw. Hefetheilchen bestimmten Rohre e befindet, um auf diese Weise ein Ansammeln von Schlammmassen und ein Verstopfen der Rohrmündung e zu verhüten (Fig. 1).In the known centrifuges for the separation of sludge, yeast the drawing u. Like. From any liquid provides one gemä'fs Fig. 2 the drum shell a b on its inner circumferential surface with inclined, curven- or angularly extending ribs or channels converge in groups in longitudinal channels c running approximately in the axial direction, specifically for the purpose of removing the sludge and respectively thrown against the conical drum shell. Feed the yeast particles to the centrifuge base d only at those points where the mouth of the orifice for the removal of the sludge is located. Yeast particles specific tubes e is located in order to prevent in this way an accumulation of sludge masses and clogging of the tube mouth e (Fig. 1).

Werden jedoch in eine derartige Centrifuge Scheidewände eingesetzt, durch welche eine Vorscheidung stattfinden oder aber der Scheideraum in radialer Richtung in schmale Lamellen zerlegt werden soll, um möglichst viele dünne Scheiderä'ume zu schaffen, dann findet gemäfs Fig. ι an den Stellen f, wo die abgeschiedenen " Schlammtheilchen die Scheideräume verlassen und gegen die Trommelwandung geschleudert werden, ein Wiedervermischen der Theilchen mit der an dieser Stelle die Scheideräume ebenfalls verlassenden und noch nicht vollständig abgesonderten Flüssigkeit statt, so dafs der ganze Scheidevorgang schädlich beeinflufst und die Wirkung der Vorscheidung bezw. der Scheidewände herabgemindert wird.However used in such a Centrifuge partitions, through which take place a pre-separation, or the separation room is to be divided in the radial direction into narrow strips to create many thin Scheiderä'ume possible, then finds gemäfs Fig. Ι f at locations where the separated "sludge particles leave the separating chambers and are thrown against the drum wall, a remixing of the particles with the liquid, which also leaves the separating chambers and which has not yet been completely separated, takes place, so that the whole separating process has a detrimental effect and the effect of the preliminary separation or the Partitions are reduced.

Zur Beseitigung dieses Uebelstandes dient die vorliegende Erfindung. Sie besteht darin, dafs der Vorscheidekegel g oder aber die sämmtlichen konischen Zwischenwände h auf ihrer inneren Umfläche mit ähnlichen Kanälen bezw. Rippen b und Kanälen c versehen sind, wie der Trommelmantel a, um auf diese Weise die auf der inneren Fläche des Vorscheidekegels bezw. der konischen Zwischenwände angesammelten Schlammtheilchen nur an bestimmten Stellen austreten zu lassen, während dazwischen die noch nicht ganz geklärte Flüssigkeit in den anderen Centrifugenraum übertritt.The present invention serves to remedy this disadvantage. It consists in the fact that the pre-separating cone g or all of the conical partition walls h on their inner circumferential surface with similar channels or respectively. Ribs b and channels c are provided, like the drum shell a, to bezw in this way on the inner surface of the Vorscheidekegel. of the conical partitions to allow the accumulated sludge particles to escape only at certain points, while in between the not yet completely clarified liquid passes into the other centrifuge space.

In der Zeichnung zeigt Fig. 1 eine mit einem derartigen Vorscheidekegel g- versehene Schlammcentrifuge im Längsschnitt. In Fig. 2 ist der in bekannter Weise mit Kanälen b und c versehene Trommelmantel α im Schnitt dargestellt. Fig. 3 zeigt den Vorscheidekegel g mit dem ZufUhrungsrohr i theilweise in Ansicht und theilweise im Schnitt. Fig. 4 veranschaulicht einen Theil des Vorscheidekegels in der Unteransicht. Fig. 5 veranschaulicht die Ueberführungsstelle des Vorscheidekegels in vergröfsertem Schnitt. In den Fig. 6, 7 und 8 sind zwei weitere Ausführungsformen des Erfindungsgegenstandes dargestellt. In the drawing, FIG. 1 shows a sludge centrifuge provided with such a pre-separating cone g- in longitudinal section. In Fig. 2 of the known manner with channels b and c provided drum shell α is shown in section. Fig. 3 shows the pre-cutting cone g with the supply pipe i partly in view and partly in section. Fig. 4 illustrates part of the pre-cutting cone in a bottom view. Fig. 5 illustrates the transfer point of the pre-cutting cone in an enlarged section. In FIGS. 6, 7 and 8, two further embodiments of the subject matter of the invention are shown.

Der mit dem Zuführungsrohr i versehene Vorscheidekegel g ist gemäfs den Fig. 3 bis 5 im Inneren ebenfalls mit schrägen, winkel- oder curvenförmig verlaufenden Ableitungsrippen bezw. Kanälen b versehen, die gruppenweise in Sammelkanäle c zusammenlaufen. Ferner ist dieser Vorscheidekegel an seinem Rande m, und zwar dort, wo die Sammelkanäle c auslaufen, mit kurzen Lappen bezw. Lamellen η ausgestattet, in welchen die Sammelkanäle c ihre Fortsetzung finden. Wird nun der Vor- The pre-cutting cone g provided with the supply pipe i is, according to FIGS.

Claims

When the separating cones are placed in the drum on the bottom d , the sludge collected in the channels c can escape towards the bottom d in the direction of the arrow r, while the sludge that has not yet been fully clarified ^; Liquid passes between the lamellae η in the arrow directions s into the other centrifuge space and can be subjected to further treatment there. A mixing of the sludge brought together in the channels c of the pre-separating cone with the liquid still to be separated does not take place when it leaves the pre-separating cone, rather both parts move separately from one another.

The effect of the centrifuge can be significantly increased if the other conical partition or partition walls, which can be arranged in the drum either in accordance with FIG. 6 or in accordance with FIG BEZW in the same way with drainage ribs. Channels b and collecting channels c and lobes respectively. Lamellae η provides in which 'the latter the collecting channel c continues.

There are in this case the b in each separation room χ secluded Schlammtheilchen through provided in the corresponding partition drains and Sarnmelkariäle c against the Centrifugenboden BEZW. guided the drum wall, without being mixed again when leaving the separating chamber with the liquid to be clarified which emerges from it at the same time and rises in the direction of the arrow.
The partition walls can have any conicity and shape and consist either of conical plates or of a screw-like turn or just of segments. They can be cast or pressed and channels b and c can be made by milling, casting or pressing. The same also applies to the pre-cutting cone g.

Furthermore, instead of the tabs η, a complete ... edge can be provided, which is provided between the outlet and collecting channels c with appropriate openings for the transfer of the liquid still to be treated.

Finally you can reverse both the pre-cutting cone and the partition walls, so with. of the conical extension facing upwards, arrange and the centrifuge upright or make it hanging.

The separated liquid flows off in the usual way through openings y .
