Description

Durch das Patent 929 062 ist eine Vorrichtung zur Durchführung von Extraktionen oder Auswaschungen von Flüssigkeiten mittels anderer Flüssigkeiten unter Verwendung eines stehenden, im wesentlichen zylindrischen Behälters mit abwechselnd eingebauten Misch- und Beruhigungskammern geschützt, bei der in den Mischkammern eine Rühreinrichtung angeordnet ist, die sowohl von der Mitte d'er Mischkammer nach außen als auch vom Umfang der Mischkammern nach innen rührend fördert. By the patent 929 062 a device for the implementation of Extractions or washing out of liquids by means of other liquids using an upright, substantially cylindrical container with alternating built-in mixing and calming chambers protected in the case of the mixing chambers a stirring device is arranged, both of the middle d'er mixing chamber after outside as well as from the circumference of the mixing chambers inwardly stirring.

Zur Herabsetzung der Bauhöhe dieser Extraktionsvorrichtungen ist es vorteilhaft, die Rühreinrichtungen, die in den Mischkammern von außen nach innen rührend fördern, in die Beruhigungskammern zu verlegen und sie mit derart herabgeminderter Umfangsgeschwindigkeit anzutreiben, daß ein Entmischen der in den Mischkammern durcheinandergewi rbelten Flüssigkeiten eintritt. To reduce the overall height of these extraction devices it is advantageous to move the stirring devices in the mixing chambers from the outside to the inside to promote touching, to relocate in the calming chambers and they with such degraded To drive peripheral speed that a segregation of the mess in the mixing chambers if fluids occur.

Dieses Entmischen wird besonders dadurch gefördert, daß man zwischen den Rühreinrichtungen in den Beruhigungskammern, die das Flüssigkeitsgemisch von außen nach innen fördern, mitumlaufende Siebe anordnet, durch die das niedersinkende Flüssigkeitsgemisch in die Längsrichtung des Extraktionsbehälters übergeführt wird.This separation is particularly promoted by the fact that between the stirring devices in the calming chambers, which the liquid mixture of conveying outside inwards, arranging circulating sieves through which the sinking Liquid mixture is transferred in the longitudinal direction of the extraction vessel.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Längsschnitt dargestellt. In the drawing, an embodiment of the invention is in longitudinal section shown.

Mit a ist ein im wesentlichen zylindrischer Behälter bezeichnet, in dem übereinanderliegend Mischkammern c mit Beruhigungskammern b abwechseln. A designates a substantially cylindrical container, alternate in the superimposed mixing chambers c with calming chambers b.

In den Mischkammern c ist je ein Rührwerks vorgesehen, das die in dem Behälter a befindlichen, sich von oben nach unten herabbewegenden Flüssigkeiten zwecks wirkungsvoller Auslaugung innig durcheinanderwirbelt und dabei von der Mitte nach außen fördert Die sämtlichen Rührwerke d eines Extraktionsbéhälters sind auf einer Vollwelle 4 angeordnet, die in beliebiger Weise angetrieben wird. A stirrer is provided in each of the mixing chambers c, which in the container a located, from top to bottom moving liquids intimately swirled around for the purpose of effective leaching and thereby from the center conveys to the outside All of the agitators d of an extraction vessel are open arranged a solid shaft 4, which is driven in any way.

Jede Beruhigungskammer b wird von mehreren übereinander angeordneten Sieben n gebildet, die sämtlich durch eine Hohlwelle i' und durch mehrere die Mischkammern c durchsetzende Stege o miteinander verbunden sind und zwischen denen mehrere Rührflügel p in Kreisform so angeordnet sind, daß sie von außen nach innen fördern. Die Hohlwelle i' wird zweckmäßigerweise in einer Drehrichtung angetrieben, die der der Rührwerke d entgegengesetzt gerichtet ist, und zwar mit einer Geschwindigkeit, die einerseits eine Beruhigung der durcheinandergemischten Flüssigkeiten ermöglicht und andererseits zwecks Aufhebung der Randgängigkeit der sich im Behälter a abwärts bewegenden Flüssigkeiten ein Hinleiten der Flüssigkeiten vom Rande des Behälters nach der Mitte herbeiführt. Each calming chamber b is arranged by several one above the other Seven n formed, all of which by a hollow shaft i 'and by several of the mixing chambers c penetrating webs o are connected to one another and between which several agitator blades p are arranged in a circle so that they promote from the outside to the inside. The hollow shaft i 'is expediently driven in a direction of rotation that is that of the agitators d is directed in the opposite direction, with a speed that on the one hand a calming of the mixed fluids allows and on the other hand for the purpose of eliminating the marginal accessibility of the liquids moving downwards in the container a brings about a passage of the liquids from the edge of the container to the middle.

PATENTANSPRVCHE: I. Vorrichtung zur Durchführung von Extraktionen oder Auswaschungen von Flüssigkeiten mittels anderer Flüssigkeiten nach Patent 929 062, dadurch gekennzeichnet, daß die in den Mischkammern von außen nach innen rührend fördernden Rühreinrichtungen (p) in die Beruhigungskammern (b) verlegt sind und mit herabgeminderter Umfangsgeschwindigkeit derart angetrieben werden, daß ein Entmischen der in den Mischkammern durcheinandergewirbelten Flüssigkeiten eintritt. PATENT CLAIM: I. Device for performing extractions or leaching of liquids by means of other liquids according to patent 929 062, characterized in that the stirring in the mixing chambers from the outside to the inside conveying stirring devices (p) are relocated to the calming chambers (b) and are driven at reduced peripheral speed in such a way that segregation the fluid swirled together in the mixing chambers enters.
