Abstract

Bei einer Zentrifuge zum Trennen von Feststoff-­ Flüssigkeitsgemischen, bei welcher mindestens eine einge­ dickte Feststoffphase mindestens teilweise durch minde­ stens eine unterhalb des Flüssigkeitsspiegels im Mantel (70) angeordnete Öffnung (73) ausgetragen wird, wobei auch Tellerpakete (80) vorgesehen sind zur Beeinflussung der Strömungsrichtung der schweren Phase. Die Problemlösung sieht vor, daß eine Steuervorrichtung (75) innerhalb des Mantels (70) zum Öffnen oder Schließen der Öffnungen (73) vorgesehen ist. Die Steuervorrichtung (75) ist mit einem Antrieb (77, 83, 86, 87, 89) ausgestattet. Der Mantel (70) ist vorzugsweise zylinderförmig ausgebildet und es sind eine oder mehrere Düsen (73) auf dem Mantel verteilt ange­ ordnet. With a centrifuge for separating solids Liquid mixtures in which at least one is turned on thick solid phase at least partially by min at least one below the liquid level in the jacket (70) arranged opening (73) is discharged, whereby also Plate packs (80) are provided to influence the Heavy phase flow direction. The problem solving provides that a control device (75) within the Sheath (70) for opening or closing the openings (73) is provided. The control device (75) is with a Drive (77, 83, 86, 87, 89) equipped. The coat (70) is preferably cylindrical and there are one or several nozzles (73) distributed on the jacket arranges.

Die Steuervorrichtungen (75) haben den Zweck, die eingedickte Feststoffphase in kontrollierter Menge und auf einfache Weise regelbar auch in Teilmengen an beliebiger Stelle im Mantelberech abziehen zu können. The control devices (75) have the purpose of thickened solid phase in a controlled amount and on easy to regulate even in subsets of any To be able to pull off the spot in the jacket area.
