Abstract

Bei einer Dekantierzentrifuge wird der Verfahrensraum von einem Druckgehäuse umschlossen, in dem in konzentri­ scher Anordnung eine Trommel und eine Schnecke gelagert sind, wobei die im Bereich der Lagerstellen gegebenen Ver­ bindungen zwischen Verfahrensraum und Atmosphäre mit Gleitringdichtungen versehen sind. Um das im Verfahrens­ raum zu verarbeitende Produkt gesteigerten Drücken und Temperaturen aussetzen zu können, wird vorgeschlagen, im Bereich der Lagerstellen zwischen der Trommel und der Schnecke jeweils eine doppelte Gleitringdichtung an­ zuordnen, die einen separaten Dichtungsraum einschließt, der innerhalb eines geschlossenen Kühl- und Schmiermi­ ttelkreislaufes gelegen ist und über einen in der Trommel gel­ egenen Verbindungskanal und eine erste Drehzuführung und über einen in der Schnecke angeordneten Verbindungskanal und eine zweite Drehzuführung an einen außerhalb des Druckgehäuses befindlichen Teil eines Kühlund Schmiermi­ ttelkreislaufes angeschlossen ist. In a decanter centrifuge, the process room enclosed by a pressure housing in which in concentric Scher arrangement a drum and a screw are, where the given in the field of bearings bonds between the process room and the atmosphere Mechanical seals are provided. To that in the process product to be processed increased pressures and Exposure to temperatures is suggested in Area of the bearing points between the drum and the Screw on a double mechanical seal assign that includes a separate seal space, the inside of a closed coolant and lubricant is located and via a gel in the drum own connection channel and a first rotary feeder and via a connecting channel arranged in the screw and a second rotary feed to an outside of the Part of a cooling and lubricating medium located in the pressure housing medium circuit is connected.
