Abstract

PCT No. PCT/EP94/01380 Sec. 371 Date May 26, 1995 Sec. 102(e) Date May 26, 1995 PCT Filed Apr. 30, 1994 PCT Pub. No. WO95/00249 PCT Pub. Date Jan. 3, 1995In a solid-jacket centrifuge drum for separating out a liquid phase, a weir is rotatable with the drum around an axis, is disposed in a path of the separated out liquid phase and has at least one channel for the separated out liquid phase. A choke plate regulates flow through the at least one channel in the weir and thereby the level of liquid inside the drum. The choke plate is stationary relative to the rotation of the weir and the drum and is axially displaceable relative to the weir to form a gap therebetween for the separated out liquid phase. The gap has a distance which is varied with the axial displacement of the choke plate.

Description

Die Erfindung betrifft ein Wehr für Vollmantelschleudertrommeln, mit mindestens einem Durchlaß zum Ablassen einer in der Schleudertrommel abgetrennten Flüssigkeitsphase, wobei dem Wehr eine axial verschiebbare Drosselscheibe zugeordnet ist.The invention relates to a weir for solid jacket centrifugal drums, with at least one passage for draining a liquid phase separated in the centrifugal drum, the weir being assigned an axially displaceable throttle disc.

Ein derartiges Wehr ist beispielsweise aus der JP 57-194 061 A2 bekannt. Dieses Wehr dient zur Regulierung einer aus der Schleudertrommel ablaufenden Feststoffmenge zwecks Erzielung einer gewünschten Feststoffkonzentration. Das Wehr rotiert mit der Schleudertrommel und ist mit einem stillstehenden, axial verschiebbaren Teil über eine Lagerstelle verbunden. Diese Lagerstelle muß gegenüber der abfließenden Flüssigkeitsphase abgedichtet sein. Derartige Lösungen sind konstruktiv aufwendig und können störanfällig sein.Such a weir is known for example from JP 57-194 061 A2. This weir is used to regulate the amount of solids running out of the centrifugal drum in order to achieve a desired solids concentration. The weir rotates with the centrifugal drum and is connected to a stationary, axially displaceable part via a bearing point. This bearing point must be sealed against the liquid phase flowing off. Such solutions are structurally complex and can be prone to failure.

Aus der DE 41 32 029 A1 ist ein Wehr bekannt, das mit einer Drallabflußkammer versehen ist, mit deren Hilfe zwei unterschiedliche Wehrdurchmesser wirksam werden können. Dadurch kann beim Anfahren in der Schleudertrommel ein Flüssigkeitsspiegel eingestellt werden, bei dem ein Flüssigkeitsdurchschlag auf der Feststoffseite verhindert wird.From DE 41 32 029 A1 a weir is known which is provided with a swirl discharge chamber, with the aid of which two different weir diameters can be effective. As a result, a liquid level can be set in the centrifugal drum when starting up, which prevents liquid breakdown on the solids side.

Häufig ist es jedoch wünschenswert, den Flüssigkeitsspiegel in der Schleudertrommel zu Erzielung eines optimalen Klär- oder Trenneffektes stufenlos einstellen zu können. Um dies zu erreichen, werden in der DE 39 21 327 A1 verschiedene Lösungen vorgeschlagen, die eine Veränderung des Übertrittsdurchmessers an dem Wehr bewirken. Die dazu erforderlichen Vorrichtungen verlangen ebenfalls eine Übertragung von Stellkräften auf rotierende Teile, was mit störanfälligen Übertragungselementen verbunden sein kann.However, it is often desirable to be able to continuously adjust the liquid level in the centrifugal drum in order to achieve an optimal clarifying or separating effect. In order to achieve this, various solutions are proposed in DE 39 21 327 A1 which bring about a change in the transition diameter on the weir. The devices required for this also require transmission of actuating forces to rotating parts, which can be associated with transmission elements susceptible to faults.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Wehr zu schaffen, das eine stufenlose Einstellung des Flüssigkeitsspiegels in der Schleudertrommel ermöglicht, ohne Stellkräfte auf rotierende Teile übertragen zu müssen.The present invention has for its object to provide a weir that allows a continuous adjustment of the liquid level in the centrifugal drum without having to transmit actuating forces to rotating parts.

Diese Aufgabe wird dadurch gelöst, daß die Drosselscheibe als stillstehendes Teil ausgebildet und am Durchlaß für eine geklärte Flüssigkeitsphase vorgesehen ist, so daß eine Einstellung des Flüssigkeitsspiegels in der Schleudertrommel durch eine axiale Verschiebung der Drosselscheibe ermöglicht wird.This object is achieved in that the throttle disk is designed as a stationary part and is provided on the passage for a clarified liquid phase, so that an adjustment of the liquid level in the centrifugal drum is made possible by an axial displacement of the throttle disk.

Es hat sich überraschend gezeigt, daß durch die stillstehende Drosselscheibe keine nachteilige Beeinflussung der Arbeitsweise der Schleudertrommel eintritt. Insbesondere trat eine ursprünglich erwartete Bremswirkung durch die den Ringspalt zwischen dem rotierenden Wehr und der stillstehenden Drosselscheibe passierende Flüssigkeit nicht auf. Der Ringspalt erzeugt einen Durchflußwiderstand, der um so größer ist, je geringer der axiale Abstand zwischen dem Wehr und der Drosselscheibe ist. Mit zunehmenden Durchflußwiderstand wird aber ein größerer Flüssigkeitsdruck am Durchlaß erforderlich, der zu einem Anstieg des Flüssigkeitsspiegels in der Schleudertrommel führt. Wird der axiale Abstand zwischen Wehr und Drosselscheibe vergrößert, so fällt der Flüssigkeitsspiegel in der Schleudertrommel bis auf einen Wert, der durch den Durchlaß des Wehres in bekannter Weise bewirkt wird.It has surprisingly been found that the stationary throttle disc does not adversely affect the operation of the centrifugal drum. In particular, an originally expected braking effect occurred due to the liquid passing through the annular gap between the rotating weir and the stationary throttle disc. The annular gap creates a flow resistance that is greater the smaller the axial distance between the weir and the throttle plate. With increasing flow resistance, however, a greater liquid pressure at the passage is required, which leads to an increase in the liquid level in the centrifugal drum. If the axial distance between weir and throttle plate is increased, the liquid level in the centrifugal drum drops to a value which is caused by the passage of the weir in a known manner.

Die axiale Verschiebung der Drosselscheibe erfolgt in vorteilhafter Weise durch eine hydraulische, eine pneumatische oder eine mechanische Vorrichtung, wobei letztere beispielsweise eine Gewindebuchse beinhalten kann.The throttle disk is advantageously axially displaced by a hydraulic, pneumatic or mechanical device, the latter being able to include, for example, a threaded bushing.

Bei einer weiteren vorteilhaften Ausgestaltung wird der Durchlaß durch mehrere Nuten gebildet, die vom Innendurchmesser des Wehres ausgehen. Durch die Form der Nuten kann die Länge der Übertrittskante für die Flüssigkeit vorbestimmt werden. Der Abflußquerschnitt für die aus der Schleudertrommel abfließende Flüssigkeit ist dabei das Produkt aus der aktiven Länge der Übertrittskante und dem Abstand zwischen dem Wehr und der Drosselscheibe.In a further advantageous embodiment, the passage is formed by a plurality of grooves which start from the inside diameter of the weir. The shape of the grooves allows the length of the trailing edge to be predetermined for the liquid. The cross-section for the liquid flowing out of the centrifugal drum is the product of the active length of the trailing edge and the distance between the weir and the throttle plate.

Eine weitere vorteilhafte Ausgestaltung ist dadurch gekennzeichnet, daß der Durchlaß durch mehrere Öffnungen gebildet wird, die in der Wandung des Wehres vorgesehen sind und einen kreisförmigen, rechteckigen oder quadratischen Querschnitt besitzen können.A further advantageous embodiment is characterized in that the passage is formed by a plurality of openings which are provided in the wall of the weir and which can have a circular, rectangular or square cross section.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachstehend näher erläutert.An embodiment of the invention is shown in the drawing and is explained in more detail below.

Mit 1 ist in der Fig. die Schleudertrommel bezeichnet, die an der Flüssigkeitsaustrittsseite mit einem Wehr 2 versehen ist, das einen Durchlaß 3 aufweist, der durch mehrere vom Innendurchmesser des Wehres ausgehende Nuten 4 oder durch in der Wandung des Wehres vorgesehene Öffnungen 5 gebildet sein kann. Dem Durchlaß 3 ist eine stillstehende Drosselscheibe 6 zugeordnet, die über eine Gewindebuchse 7 axial verschiebbar ist.1 in the figure is the centrifugal drum, which is provided on the liquid outlet side with a weir 2 which has a passage 3 which is formed by a plurality of grooves 4 extending from the inside diameter of the weir or by openings 5 provided in the wall of the weir can. The passage 3 is assigned a stationary throttle disc 6, which is axially displaceable via a threaded bushing 7.

Durch Verdrehen der Gewindebuchse 7 kann der Abstand zwischen dem Wehr 2 und der Drosselscheibe 6 verändert werden. Dadurch verändert sich für die aus der Schleudertrommel 1 ablaufende Flüssigkeit der Abflußquerschnitt, der gebildet wird durch die Gesamtlänge der Übertrittskante des Durchlasses 3 und dem Abstand zwischen dem Wehr 2 und der Drosselscheibe 6. Die Veränderung des Abflußquerschnittes bewirkt eine Änderung des Flüssigkeitsspiegels in der Schleudertrommel 1, so daß eine stufenlose Einstellung dieses Flüssigkeitsspiegels durch Verschiebung der Drosselscheibe 6 ermöglicht wird.The distance between the weir 2 and the throttle plate 6 can be changed by rotating the threaded bushing 7. This changes the discharge cross-section for the liquid running out of the centrifugal drum 1, which is formed by the total length of the trailing edge of the passage 3 and the distance between the weir 2 and the throttle disc 6. The change in the discharge cross-section causes a change in the liquid level in the centrifugal drum 1 so that a stepless setting this liquid level is made possible by displacement of the throttle disc 6.
