Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Abdichten der Elektroden von Elektroschmelzöfen, und zwar handelt es sich um eine solche Vorrichtung, die aus teleskopartig ineinandergeschobenen Röhren besteht,The invention relates to a device for sealing the electrodes of Electric melting furnaces, namely one such device that consists of telescopic consists of tubes pushed into one another,

• -die durch Dichtungsringe oder Stopfbüchsen gegeneinander abgedichtet sind, und von denen das innere auf dem Ofengewölbe ruht und das äußere an der Elektrode luftdicht abschließend befestigt ist.• -which are sealed against each other by sealing rings or stuffing boxes, and by which the inner one rests on the furnace vault and the outer one is airtight on the electrode is attached.

Das Neue besteht darin, daß zwischen dem an der Elektrode befestigten äußeren Zylinder und dem inneren, auf dem Ofengewölbe ruhenden Zylinder ein weiterer Zylinder eingeschoben ist, der an der Tragkonstruktion für die Elektroden befestigt ist und gegen den die beiden anderen Zylinder durch Dichtungsringe abgedichtet sind.The novelty is that between the outer cylinder attached to the electrode Another cylinder is inserted into the inner cylinder resting on the furnace vault which is attached to the support structure for the electrodes and against which the other two cylinders by sealing rings are sealed.

Der Hub des äußeren Zylinders wird hierdurch unabhängig von der Höhe des meistens durch Wasser gekühlten inneren Zylinders·, und außerdem ist der besondere Vorteil gegeben, daß die eigentliche Abdichtung durch zwei keinerlei Verschiebungen durch Wachsen des Ofengewölbes o. dgl. unterworfene Zylinder erfolgt, sofern man, was ohne weiteres möglich ist, den äußeren Zylinder am Traggerüst für die Elektroden führt.The stroke of the outer cylinder is thereby mostly independent of the height of the inner cylinder cooled by water, and there is also the special advantage that the actual seal by two no shifts whatsoever due to the growth of the Oven vault or the like. Subject cylinder takes place, provided that what is easily possible is, leads the outer cylinder on the support structure for the electrodes.

Ein Ausführungsbeispiel dieser Art ist in der Zeichnung im Längsschnitt dargestellt. 3aAn embodiment of this type is shown in the drawing in longitudinal section. 3a

Mit χ ' ist das Ofengewölbe angedeutet, durch das in bekannter Weise die Elektrode 2 hindurchgeführt ist. Diese hängt vermittels der Klemme 3 und des Abschlußdeckels 4 für den Zylinder 5 an den Zugmitteln 6, die über die Rollen 7 auf dem Gerüst 8 zu einem nicht gezeichneten Windewerk zu führen. Das Gerüst 8 ist in bekannter Weise an dem Ofen angeordnet und dient vermittels der Gleitschuhe 9 im Ausführungsbeispiel als feste Führung für das äußere Teleskoprohr 5, das durch den Dichtungsring 10 gegen den äußeren Mantel eines eingeschobenen Zylinders 11 abgedichtet ist. Letzterer ruht auf der denWith χ 'the furnace vault is indicated, through which the electrode 2 is passed through. This hangs by means of the clamp 3 and the cover plate 4 for the cylinder 5 on the traction means 6, which via the rollers 7 on the frame 8 to one to lead winch not shown. The framework 8 is in a known manner on the furnace arranged and is used by means of the sliding shoes 9 in the embodiment as a fixed Guide for the outer telescopic tube 5, which by the sealing ring 10 against the outer Jacket of an inserted cylinder 11 is sealed. The latter rests on the den

inneren Zylinder 12 umfassenden Ringscheibe 13, die ihrerseits an dem Gerüst 8 befestigt ist. Der Zylinder 12 ist in üblicher Weise doppelwandig ausgeführt und durch einen weiteren Dichtungsring 14 ebenfalls gegen den festen Zylinder 11 abgedichtet. Statt des Dichtungsringes 14 kann natürlich jede beliebige Dichtungsvorrichtung, die eine relative Verschiebung zwischen Zylinder 12 und 11 gestattet, angeordnet werden. Beispielsweise läßt sich eine Sanddichtung ohne weiteres' anwenden, da nur geringe Relativbewegungen zwischen Zylinder 11 und 12 durch Wachsen des Ofengewölbes in Betracht kommen.inner cylinder 12 comprising annular disk 13, which in turn is attached to the frame 8 is. The cylinder 12 is made double-walled in the usual way and by another Sealing ring 14 is also sealed against the fixed cylinder 11. Instead of Sealing ring 14 can of course be any Sealing device that allows relative displacement between cylinders 12 and 11 allowed to be arranged. For example, a sand seal can be easily ' use, since only slight relative movements between cylinders 11 and 12 due to waxing of the furnace vault come into consideration.
