Description

Verschlußmittel für die ringförmige Schlammauslaßöffnung einer vollwandigen Schleudertrommel Gegenstand des Patents 621 391 ist ein V erschlußmittel für die ringförmige Schlammauslaßöffnung einer vollwandigen Schleudertrommel und besteht in einer die Öffnung verschließenden biegsamen Ringscheibe, welche mit ihrem inneren Rand fest an einer der beiden Trommelhälften eingespannt ist und mit ihrem äußeren Rand durch ein Druckmittel gegen die andere Trommelhälfte abdichtend angepreßt wird.Closure means for the annular sludge outlet opening of a full-walled Centrifugal drum The subject of patent 621 391 is a closure means for annular sludge outlet opening of a full-walled centrifugal drum and consists in a flexible annular disc which closes the opening and which with its inner Edge is firmly clamped to one of the two drum halves and with its outer Edge is pressed sealingly against the other drum half by a pressure medium.

Die vorliegende Erfindung bezweckt, *ein Mittel zu schaffen, welches verhindert, daß die biegsame Ringscheibe unmittelbar der abnützenden Wirkung des Schlammes beim Auslaß unterworfen ist und daß der nachgiebige Baustoff, aus denn die Ringscheibe besteht, beim Öffnen des Verschlusses durch die Schleuderkraft in den Öffnungsspalt gedrückt wird.The present invention aims to provide a means which prevents the flexible ring washer directly from the wear and tear of the Sludge at the outlet is subject and that the resilient building material, from then the washer exists when the closure is opened by the centrifugal force in the opening gap is pressed.

Dies soll erfindungsgemäß dadurch erreicht werden, daß der äußere von dem Druckring bewegte Rand der biegsamen Ringscheibe durch einen auswechselbaren Deckring formerhaltend eingefaßt ist, welcher gegen die Dichtungsfläche andruckbar ist. Dabei kann sich die Dichtungsfläche in dem anderen oder auch in bekannter Weise in dem gleichen Trommelteil befinden wie das Verschlußmittel.This is to be achieved according to the invention in that the outer by the pressure ring moved edge of the flexible annular disc by an exchangeable one Cover ring is framed in a shape-retaining manner, which can be pressed against the sealing surface is. The sealing surface can be in the other or in a known manner located in the same drum part as the closure means.

Die Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel dargestellt.The invention is shown in the drawing in an exemplary embodiment.

Die Schleudertrommel besteht aus den beiden Trommelhälften i und 2, die mit ihren Flanschen io und 9 miteinander verschraubt sind. Der Trommelteil e weist einen Austragsspalt i i auf, der durch ein Verschlußmittel verschlossen gehalten ist. Dieses Verschlußmittel besteht aus einer biegsamen Ringscheibe 6, deren innerer Rand in dein Trommelteil 2 fest eingespannt ist. Der äußere Rand der Scheibe wird durch einen Druckring 5 mit Hilfe der Druckstangen 5a gegen den auswechselbaren Dichtungsring ig der Dichtungsfläche 7 angedrückt. Um zu verhindern, daß der äußere Rand der biegsamen Ringscheibe 6 in unmittelbare Berührung mit dem ausfließenden Schlamm tritt und dadurch zu schnell abgenutzt wird, ist dieser Rand durch einen Deckring 8, welcher auswechselbar mit dem Druckring 5 verbunden ist, verkleidet. Hierdurch wird auch gleichzeitig verhindert, daß Teile der biegsamen Ringscheibe 6 durch die Wirkung der Fliehkraft in den Abdichtungsspalt gelangen können.The centrifugal drum consists of the two drum halves i and 2, which are screwed together with their flanges io and 9. The drum part e has a discharge gap i i which is kept closed by a closure means is. This closure means consists of a flexible washer 6, the inner Edge is firmly clamped in your drum part 2. The outer edge of the disc will by a pressure ring 5 with the help of the push rods 5a against the replaceable Sealing ring ig the sealing surface 7 is pressed. To prevent the external Edge of the flexible washer 6 in direct contact with the outflow If mud occurs and is worn too quickly, this edge is through one Cover ring 8, which is interchangeably connected to the pressure ring 5, disguised. This also prevents parts of the flexible annular disc from being removed at the same time 6 can get into the sealing gap by the effect of centrifugal force.

Der Auslaßschlitz i i kann in bekannter Weise in dem einen Trommelteil oder auch zwischen beiden Trommelteilen vorgesehen sein.The outlet slot i i can in a known manner in the one drum part or be provided between the two drum parts.
