DekanterzentrifugeDecanter centrifuge

Die Erfindung betrifft eine Dekanterzentrifuge mit einer von einem Hauptantriebsmotor angetriebenen Trommel und einer innerhalb der Trommel drehbar angeordneten Schnecke.The invention relates to a decanter centrifuge having one of a Main drive motor driven drum and a screw rotatably arranged within the drum.

Eine Dekanterzentrifuge besteht bekanntlich aus einer Trommel und einsr koaxial in dieser angeordneten Schnecke, beide drehbar gelagert mit Ein- und Auslassöffnungen für die am Prozess beteiligten Medien. Die Aufgabe des Antriebes besteht darin. Schnecke" und Trommel auf eine relativ hohe Drehzahl zu bringen, wobei eine kleine Schlupfdrehzahl zwischen Trommel und Schnecke .' gewährleistet werden soll, damit die Schnecke das trockene, schwere Gut aus der Trommel befördern kann. Diese Aufgabe wird bei bekannten Dekanterzentrifugen durch ein Planeten- oder AbwMlzgetriebe übernommen, wodurch jedoch die Schlupfdrehzahl starr an di,e Antriebsdrehzahl gekoppelt ist. Oft wird jedoch eine vonAs is well known, a decanter centrifuge consists of a drum and one screw located coaxially in this, both rotatable stored with inlet and outlet openings for those involved in the process Media. The task of the drive consists in this. To bring the screw "and the drum to a relatively high speed, with a small slip speed between the drum and the screw. ' is to be guaranteed, so that the screw the dry, can transport heavy goods out of the drum. In known decanter centrifuges, this task is performed by a planetary or roller gear taken over, whereby, however, the slip speed is rigidly coupled to di, e drive speed. Often, however, one of

der Äntriebsdrehzahl unabhängig einstellbare Schlupfdrehzahl. verlangt, insbesondere wenn das Trenngut, wie beispielsweise in Kläranlagen, in seiner Konsistenz unregelmässig ist.the drive speed independently adjustable slip speed. required, especially if the material to be separated, such as in sewage treatment plants, is irregular in its consistency.

Die vorliegende Erfindung bezweckt, einen von der •Antriebsdrehzahl unabhängigen, frei einstellbaren Dekanter-Schlupfantrieb zu schaffen, Die Erfindung beruht auf der Erkenntnis, dass die erforderlichen grossen Drehmomente auf den Schlupfantrieb beschränkt bleiben sollen, den Hauptantrieb also nicht belasten dürfen»The present invention aims to provide a freely adjustable decanter slip drive that is independent of the drive speed to create, The invention is based on the knowledge that the required large torques on the slip drive should remain limited, so must not load the main drive »

Erfindungsgemäss ist die Dekanterzentrifuge dadurch gekennzeichnet, dass zur Erzeugung der Schlupfdrehzahl zwischen der Trommel und der Schnecke zusätzlich ein Hydromotor angeordnet ist, dessen Gehäuse mit der Trommel und dessen Welle mit der Schnecke fest verbunden ist, und dass zur Zuführung eines Hydraulikmetiiums zum Hydromotor Drehdurchführungen vorgesehen sind.According to the invention, the decanter centrifuge is characterized in that that a hydraulic motor is additionally arranged between the drum and the worm to generate the slip speed is, whose housing is firmly connected to the drum and whose shaft is connected to the worm, and that for feeding a Hydraulic fluid provided for the hydraulic motor rotary unions are.

Ein Ausfuhrungsbeispxel des Erfindungsgegenstandes wird nachstehend anhand der Zeichnung erläutert.An exemplary embodiment of the subject matter of the invention is given below explained with reference to the drawing.

In einem Maschinengehäuse 1 der Dekanterzentrifuge ist eine Trommel 2 über ein Lager 3 und eine Gehäuselagerung 4 eines Schlupfhydromotors 5 gelagert. In der Trommel 2 ist koaxial eine Schnecke 6 durch ein Lager 7 und die Wellenlagerung des Schlupfhydromotors 5 nochmals gelagert. Die Trommel 2 wird über das Gehäuse 51 des Schlupfhydromotors 5 durch die Welle θ eines ebenfalls als Hydromotor ausgebildeten Hauptantriebsmotors 9 angetrieben, die grosse Drehmomentbelastung zwischen der Schnecke B und der Trommel 2 bleibt jedoch auf den Schlupfhydromotor beschränkt, der über eine Welle 10 die Schnecke 6 auf die gewünschte Schlupfdrehzahl gegenüber der Trommel 2 bringt.A drum 2 is mounted in a machine housing 1 of the decanter centrifuge via a bearing 3 and a housing mounting 4 of a slip hydraulic motor 5. In the drum 2, a worm 6 is again supported coaxially by a bearing 7 and the shaft bearing of the slip hydraulic motor 5. The drum 2 is driven via the housing 5 1 of the slip hydraulic motor 5 by the shaft θ of a main drive motor 9, which is also designed as a hydraulic motor, but the high torque load between the worm B and the drum 2 remains limited to the slip hydraulic motor, which drives the worm via a shaft 10 6 brings it to the desired slip speed with respect to drum 2.

Der Schlupfhydromotor 5 wird von einer variablen Verdrängerpumpe 11 über eine Leitung 12 und eine Drehdurchführung 13 mit einem Hydraulikmedium gespeist. Ueber ein Stromregelventil 14 wird eine kleine Leistung für den Häuptantriebsmotor 9 abgezweigt. Ein Leitungssystem 15 führt den Rücklaufstrom des Hydraulikmediums, der sowohl vom feststehenden Hauptantriebsmotor wie vom mitrotierenden Schlupfmotor 5 anfällt. The slip hydraulic motor 5 is driven by a variable displacement pump 11 via a line 12 and a rotary leadthrough 13 fed with a hydraulic medium. A small amount of power for the main drive motor 9 is diverted via a flow control valve 14. A line system 15 carries the return flow of the hydraulic medium, which occurs both from the stationary main drive motor and from the co-rotating slip motor 5.

Selbstverständlich können Haupt- und Schlupfmotor mit je einer separaten Antriebspumpe beaufschlagt werden. Als Schlupfhydromotor 5 kommt nur ein in sich ausgewuchteter Langsamläufer in Frage, da er als Ganzes mit der hohen Antriebsdrehzahl rotiert.Of course, the main and slip motor can each be supplied with a separate drive pump. As a slip hydraulic motor 5 only a balanced slow runner comes into question, since it rotates as a whole at the high drive speed.

Als· Drehdurchführung wird mit Vorteil eine hydrostatische Wellendurchführung gemäss Schweizer Patent Nr. 526 OBl oder 545 933 verwendet. A hydrostatic shaft lead-through is advantageously used as the rotary lead-through used in accordance with Swiss Patent No. 526 OBl or 545 933.
