Abstract
Description
Die Erfindung betrifft eine Vollmantel-Schneckenzentrifuge zum kontinuierlichen Trennen von Stoffen unterschiedlicher Dichte nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a solid bowl screw centrifuge for continuous separation of materials of different densities according to the preamble of patent claim 1.
Aus
Der Erfindung liegt die Aufgabe zugrunde, eine Schneckenzentrifuge nach dem Oberbegriff des Patentanspruchs 1 so auszubilden, dass die Suspension nicht in die Flüssigkeitskammer zurückströmen kann, wo sie Verstopfungen verursachen würde.The invention has the object of providing a screw centrifuge according to the preamble of claim 1 in such a way that the suspension can not flow back into the liquid chamber, where it would cause blockages.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass die Flüssigkeitskammer in Förderrichtung des Flüssigkeitsrohres und des Zulaufrohres vor der Aufgabekammer angeordnet ist.To achieve this object, the invention provides that the liquid chamber is arranged in the conveying direction of the liquid tube and the inlet pipe in front of the feed chamber.
Zur weiteren Verbesserung ist zwischen der Flüssigkeitskammer und der Aufgabekammer in der Hohlwelle der Förderschnecke eine Vorkammer ausgebildet, wodurch im Anschluss an die Flüssigkeitskammer ein Puffer mit einer Labyrinthwirkung erzeugt wird, so dass möglicherweise zurückströmende Suspensionsanteile nicht in die Flüssigkeitskammer gelangen können.For further improvement, an antechamber is formed between the liquid chamber and the feed chamber in the hollow shaft of the screw conveyor, whereby a buffer with a labyrinth effect is produced subsequent to the liquid chamber, so that possibly flowing back suspension components can not get into the liquid chamber.
Nach einem weiteren Merkmal der Erfindung sind die Flüssigkeitskanäle in der Wandung der Hohlwelle der Förderschnecke ausgebildet und über Radialbohrungen mit der Flüssigkeitskammer verbunden. Mit dieser Maßnahme wird die Flüssigkeit im Schneckenkörper an der Aufgabekammer vorbei geführt. Durch die Rotation der Förderschnecke wird ein hoher Druck erzeugt, der bei einer Umdrehungszahl von 4500 U/min 6,5 bar und mehr betragen kann, wodurch Verstopfungen vermieden werden, weil der hohe Druck selbstreinigend wirkt.According to a further feature of the invention, the liquid channels are formed in the wall of the hollow shaft of the screw conveyor and connected via radial bores with the liquid chamber. With this measure, the liquid in the screw body is guided past the task chamber. By the rotation of the screw conveyor, a high pressure is generated, which can be at a speed of 4500 rev / min 6.5 bar and more, whereby blockages are avoided because the high pressure acts self-cleaning.
