Abstract

Dekanter für die Trennung von Suspensionen mit einem Maschinenbett (1), einer auf diesem drehbar abgestützten Trommel (3), einer in dieser mit Differenzdrehzahl umlaufend gelagerten Schnecke (4), einem zwischen die Trommel und die Schnecke eingeschalteten Getriebe (5), einem an dieses bzw. die Rotationseinheit aus Trommel und Schnecke über eine Drehmomentübertragungseinrichtung angeschlossenen, ebenfalls an dem Maschinenbett (1) abgestützt gehaltenen Antriebsmotor (6) und mit Zu- und Ableitungen sowie gegebenenfalls Hilfsaggregaten, die ebenfalls an dem Maschinenbett (1) gehalten sind. Eine solche Dekanteranlage bildet über das Maschinenbett (1) verbunden ein Massensystem, bei welchem kritische Eigenschwingungen möglichst umgangen bzw. gedämpft werden sollen. Dazu ist die Dekanteranlage derart ausgebildet, daß zumindest eines der an dem Maschinenbett (1) gehaltenen Bauteile und/oder Hilfsaggregate von den anderen an dem Maschinenbett gehaltenen Bauteilen in mindestens einer mit einer parallel zur Drehachse des Dekanters gerichteten Komponente verlaufenden Richtung, ausgenommen die Richtung der Antrieb-Drehmomentübertragung, durch elastische Halterung entkoppelt und/oder mittels eines Dämpfungsgliedes mit den anderen Bauteilen gekoppelt ist. Decanter for the separation of suspensions with a Machine bed (1), one on this rotatably supported drum (3), one in this worm (4), which is mounted around the circumference with differential speed, one between the drum and the snail gearbox (5) switched on, one on this or the rotating unit of drum and screw over a Torque transmission device connected, also to the Machine bed (1) supported drive motor (6) and with feed and Discharges and, if necessary, auxiliary units, which are also on the Machine bed (1) are held. A such decanter plant forms about that Machine bed (1) connected a mass system, in which critical Natural vibrations should be avoided or damped as far as possible. For this purpose, the decanter system is designed such that at least one of the on the machine bed (1) held components and / or auxiliary units the other components held on the machine bed in at least one with a parallel to the axis of rotation of the decanter Component direction, except the direction of the Drive torque transmission, decoupled by elastic bracket and / or by means of an attenuator with the other components is coupled.
