Abstract

Bei diesem am Außenumfang angetriebenen und auf Rollen laufenden Drehrohr (2) mit im Bereich der an die Drehrohrenden anschließenden Drehrohrköpfe (12) vorgesehenen Leitungen bzw. Stutzen für Produkteintritt, Produktgasabzug und Feststoffaustritt zur thermischen Behandlung, Schwelung oder Pyrolyse flüssiger oder fester Stoffe oder Mischphasen mittels indirekter Beheizung wird zwecks verbesserter Dichtfunktion und erhöhter Standzeit der Dichtungspackungen zwischen den bewegten und den stehenden Teilen des Drehrohres (2) eintritts- und austrittsseitig je ein schwimmendes Gleitringdichtungssystem (3,4,5) vorgesehen. Mittels je einer kraftschlüssigen Rahmenkonstruktion (8) wird eine Drehverbindung zwischen dem Drehrohr (2) und den beiden mit den Leitungen bzw. Stutzen verbundenen stationären Drehrohrköpfen (12) ermöglicht.
