Description

Beim Betriebe von Rührwerks-Flotationsmaschinen hat sich der Übelstand ergeben, daß durch die der Flotationszelle von der Seite her zugeführte und vom Rührer angesaugte Trübe die Rührwerkswelle im Bereich des Einlaufes durch die feinen Erz- und Bergeteilchen einem starken Verschleiß unterworfen ist. Um diesem übelstand abzuhelfen, ist bereits die Rührwerkswelle im Bereich des Trübeeinlaufes gummiert bzw. mit einer Gummihülse versehen worden. Aber auch diese Maßnahmen haben nicht den gewünschten Erfolg gebracht.In the operation of agitator flotation machines, the problem has become show that by the flotation cell fed from the side and from Turbidity sucked in by the agitator shaft in the area of the inlet through the fine Ore and mountain particles are subject to severe wear. To this evil To remedy this, the agitator shaft is already rubberized in the area of the sludge inlet or have been provided with a rubber sleeve. But even these measures do not have brought the desired success.

Die Erfindung beseitigt diesen Nachteil durch eine im Bereich des Trübeeinlaufes auf die abgesetzte Rührwerkswelle mit Spiel aufgeschobene Hülse aus verschleißfestem Werkstoff, die an ihren beiden Enden nach innen abgeschrägt und unter Zentrierung durch je eine Gummiringdichtung zwischen einer oder mehreren Abstandsscheiben einerseits und der Nabe des Rührers andererseits eingespannt ist.The invention eliminates this disadvantage by a in the field of Slurry inlet onto the offset agitator shaft with the sleeve pushed onto it wear-resistant material, which beveled inwards at both ends and centered by a rubber ring seal between one or more spacer washers on the one hand and the hub of the stirrer on the other hand is clamped.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.

In der Flotationszelle I ist in bekannter Weise die Rührwerkswelle 2 angeordnet, an deren unterem Ende der Rührer 3 lösbar befestigt ist. Der Zulauf der aufzubereitenden Trübe erfolgt von der Seite her durch den Kanal 4. Im Bereich des Trübeein-Laufes ist die Antriebswelle 2 abgesetzt und darüber mit Spiel die Hülse 5 aus verschleißfestem Werkstoff aufgeschoben. Die Hülse 5 ist an ihren beiden Enden abgeschrägt. Zwischen der Hülse 5 und dem Absatz der Welle 2 sind Abstandsscheiben 6 angeordnet, von denen eine oder mehrere vorhanden sein können, um die Höhe der Hülse 5 einstellen zu können. Zwischen diesen Abstandsscheiben 6 einerseits und der Nabe des Rührers 3 andererseits sind Gummiringdichtungen 7 eingelegt, die die Hülse 5 gegenüber der Welle 2 zentrieren und eine vollständige Andichtung bewirken, so daß die Trübe nicht mit der Welle 2 in Berührung kommen kann. Durch Lösen der Schraube 8 und Abziehen des Rührers 3 kann in einfacher Weise ein Auswechseln der Hülse 5 vorgenommen werden.The agitator shaft is in the flotation cell I in a known manner 2 arranged, at the lower end of which the stirrer 3 is releasably attached. The inflow the pulp to be processed is carried out from the side through channel 4. In the area of the Trübeein-Laufes the drive shaft 2 is deposited and above it with the game Sleeve 5 made of wear-resistant material pushed on. The sleeve 5 is on both of them Beveled ends. Spacer washers are located between the sleeve 5 and the shoulder of the shaft 2 6 arranged, of which one or more may be present to increase the height of the Sleeve 5 to be able to adjust. Between these spacers 6 on the one hand and the hub of the stirrer 3 on the other hand, rubber ring seals 7 are inserted, which the Center the sleeve 5 in relation to the shaft 2 and create a complete seal, so that the sludge cannot come into contact with shaft 2. By solving the Screw 8 and pulling off the stirrer 3 can be replaced in a simple manner Sleeve 5 can be made.
