Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Abdichtung der Elektroden von Elektroschmelzöfen, die aus einem zylindei'-förmigen doppelvvandigen Zylinder besteht, in dessen durch Wasser gekühlten Ringraunx eine dicht an der Elektrode befestigte Haube eingetaucht ist.The invention relates to a device for sealing the electrodes of Electric melting furnaces, which consist of a cylindei'-shaped double-walled cylinder, in its water-cooled ringraunx a hood attached close to the electrode is immersed.
Nach einem bekannten Vorschlag findet der Wasserzufluß in den Kühlmantel durch ein von außen am Fuß des Kühlmantels in diesen einmündendes Rohr statt, während der Abfluß durch ein höher gelegenes, ebenfalls an der Außenseite in den Kühlzylinder einmündendes Rohr erfolgt.According to a known proposal, the water flows into the cooling jacket through a from the outside at the foot of the cooling jacket in this opening tube instead, while the drain through a higher located one that also opens into the cooling cylinder on the outside Tube takes place.
Diese bekannte Ausführung hat den Nachteil, daß das Wasser zwischen der einge* tauchten Abschlußhaube und der inneren Wand des Kühlzylinders mehr oder weniger in Ruhe bleibt und an der Zirkulation nichtThis known design has the disadvantage that the water between the incorporated * dipped cover and the inner wall of the cooling cylinder remains more or less at rest and does not participate in the circulation
so teilnimmt, so daß das Wasser einer starken.so participates, so that the water is a strong one.
Verdampfung unterworfen ist, wodurch nicht nur die Kühlwirkung vermindert wird, sondern auch bei offenem Kühlraum die nachteilige Erscheinung eintritt, daß das Wasser in den Herdraum eindringt und hier schädlich auf das Bad einwirkt. Bei oben geschlos* senem Kühlwasserringraum besteht die Gefahr einer Dampfpufferbildung, die ihrerseits das Durchschmelzen der Zylindermäntel im Gefolge haben kann.Is subject to evaporation, whereby not only the cooling effect is reduced, but even when the refrigerator is open, the disadvantageous phenomenon occurs that the water penetrates into the oven and is harmful here acts on the bathroom. If the cooling water annulus is closed at the top, there is a risk a vapor buffer formation, which in turn causes the cylinder jackets to melt through in the May have entourage.
Diesen besprochenen Nachteilen wird durch die Erfindung begegnet, und zwar dadurch, daß der obere Abfluß des Kühlwassers aus dem Ringraum des doppelwandigen Zylinders innerhalb der eingetauchten Abschlußhaube, erfolgt.These disadvantages discussed are countered by the invention, namely by that the upper drain of the cooling water from the annulus of the double-walled cylinder inside the submerged cap.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch im Längsschnitt dargestellt.In the drawing, an embodiment of the invention is shown schematically in longitudinal section shown.
Die durch das Ofengewölbe 1 hindurch-The through the furnace vault 1
geführte Elektrode ist mit 2 bezeichnet und vermittels der Klemme 3 und der Scheibe 4 an den Zugorganen 5 heb- und senkbar aufgehängt. Die Platte 4 trägt den Tauchzylinder 6, der im Ausführungsbeispiel ebenfalls doppelwandig mit Wasserumlauf dargestellt ist, jedoch natürlich auch einwandig ausgeführt werden kann. Dieser Zylinder 6 ist in den Ringraum des doppelwandigen Zylinders 7 eingeführt, der im Ausführungsbeispiel oben mit einem Deckel 10 versehen ist, welcher gegen den Tauchzylinder 6 in geeigneter Weise abgedichtet werden kann. Der Deckel kann jedoch auch wegfallen. Bei dem Kühlzylinder 7 erfolgt der Wasserzufluß durch die Stützen 8, während der Abfluß durch das zwischen dem Zylinder 6 und der inneren Wand des Zylinders 7 hochgeführte, oben offene Rohr 9 erfolgt. Der Wasserabfluß findet also an der der Elektrode 2 zugekehrten Seite aus dem Zylinder 7 statt, so daß die oben geschilderten Nachteile der bekannten Elektrodenabdichtung vermieden sind.The guided electrode is denoted by 2 and by means of the clamp 3 and the washer 4 suspended from the pulling members 5 so that they can be raised and lowered. The plate 4 carries the immersion cylinder 6, which is also shown double-walled with water circulation in the exemplary embodiment is, but can of course also be single-walled. This cylinder 6 is introduced into the annular space of the double-walled cylinder 7, which is provided with a cover 10 at the top in the exemplary embodiment is, which can be sealed against the immersion cylinder 6 in a suitable manner. However, the cover can also be omitted. In the case of the cooling cylinder 7, the water inflow takes place through the supports 8, while the drainage through that between the cylinder 6 and the inner wall of the cylinder 7 raised, open-top tube 9 takes place. The water drainage therefore takes place at the electrode 2 facing side from the cylinder 7 instead, so that the above-described disadvantages of known electrode seal are avoided.
