Description

In modernen Betrieben muß- mit Rücksicht auf die Gesunderhaltung des Betriebspersonals für eine gute Entlüftung gesorgt werden. Bei allen Elektroöfen und metallurgischen Ofen, insbesondere Karbid- und Roheisenöfen usw., erfolgt während des Abstiches eine starke Oualmentwicklung, die, wenn nicht entsprechende Vorrichtungen vorhanden sind, eine Verräucherung der Arbeitshallen verursachen.In modern companies, with consideration for maintaining the health of the Operating personnel must be provided with good ventilation. With all electric ovens and metallurgical furnace, particularly carbide and pig iron furnaces, etc., takes place during of racking a strong oual development, which, if not appropriate devices are present, cause smoke build-up in the work halls.

Bei feststehenden Ofen ist die Abführung der Abstichschwaden durch Anordnung einer Haube verhältnismäßig einfach zu erreichen. Bei rotierenden Ofen, bei denen die Abstichöffnung mitwandert, genügt die Anordnung einer rings um den Ofen verlaufenden einfachen Haube den an sie -zu stellenden Anforderungen nicht mehr. Die Anordnung einer einfachen Haube würde die Zufuhr von großen Mengen an Beiluft -begünstigen und -damit - i. die volle Entfernung der Abstichschwaden verhindern und 2. unwirtschaftlicher arbeiten.In the case of a stationary furnace, the removal of the tapping fumes is relatively easy to achieve by arranging a hood. In the case of rotating furnaces in which the tapping opening moves along with it, the arrangement of a simple hood running around the furnace is no longer sufficient to meet the demands made on it. The arrangement of a simple hood would -favor the supply of large amounts of auxiliary air and - thus - i. prevent the full removal of the tapping swaths and 2. work less economically.

Die Erfindung bezweckt, diese Nachteile. durch die Anordnung zweier ringförmiger Abstichhauben zu vermeiden. Die untere Abstichhaube bewegt sich zusammen mit dem Ofengefäß. Die-obere Abstichhaube dagegen ist fest angeordnet und erhält ent- -sprechend der auftretenden Abstichschwadenmenge einen oder mehrere Anschlußstutzen für den Anschluß der ins Freie führenden Rohrleitungen. Die Abdichtung der unteren und der oberen_Gasabzug-shaube erfolgt durch eine Sandtassen- oder Flüssigkeitsdichtung. Die untere Gasabzugshaube besitzt in ihrem oberen Teil Öffnungen im Bereich der Absticho;--durch rlie die Abstiehschwaden in-die obere Gasabzugshaube eintreten und die dann durch die bereits obenerwähnten Rohrleitungen ins Freie geführt werden.The invention aims to address these disadvantages. by arranging two avoid ring-shaped tapping hoods. The lower tapping hood moves together with the furnace vessel. The upper tapping hood, on the other hand, is fixed and maintained one or more connecting pieces according to the amount of tapping steam that occurs for the connection of the pipelines leading to the outside. Sealing the lower and the upper_gas extractor hood is done through a sand cup or liquid seal. The upper part of the lower gas extractor hood has openings in the area of the Tapping; - Enter the upper gas extractor hood through the draining fumes and which are then led into the open air through the pipelines already mentioned above.

In der Zeichnung ist ein Ausführungsbeispiel'der Erfindung dargestellt. - -Die Ofenwanne i ist auf Rollen 2 drehbar abgestützt, so daß sie sowohl eine um die Achse 3 hin und her schwingende Bewegung als auch eine vollständige Drehbewegung ausführen kann. Infolgedessen wandert auch die Lage der Abstichöffnung :4. Es können auch mehrere Abstichöffnungen vorgesehen werden. An der Abstichstelle entstehen Gasschwaden, die für die Bedienungsleute eine recht unangenehme Belästigung darstellen. Um einesteils diese Gase an der jeweiligen Abstichstelle abziehen zu können, andererseits aber das Ansaugen von Nebenluft an allen anderen Stellen zu vermeiden, ist ein ringförmiger Kanal 5 vorgesehen, dessen unterer Teil 5a mit der Ofenwanne i drehbar oder schwenkbar ist und dessen oberer Teil 5b feststeht und an ein oder mehrere Abzugsrohre 6 angeschlossen ist. Zwischen den beiden Teilen des Ringkanals befinden sich Abdichtungen 7, z. B. Flüssigkeitsdichtungen oder sogenannte Sandtassen. -CTTber jeder Abstichstelle 4 ist eine Ofnung 8 im Boden des Teiles 5a angebracht, so daß die Gase in den Kanal 5 übertreten können. Ein Schirm 9 leitet die Gase zu dieser übertrittsstelle hin. Die Erfindung bietet also die Möglichkeit, den Schwaden an beliebiger Stelle ohne große Nebenluftmengen abziehen zu können, und zwar so, daß dadurch die Aufbauten auf dem Ofendeckel io nicht gestört werden. Man ist also in der Anordnung der Füllschächte ii und der Elektroden r2 samt ihren Dichtungen völlig frei.An exemplary embodiment of the invention is shown in the drawing. - The furnace pan i is rotatably supported on rollers 2, so that it can be both a the axis 3 reciprocating motion as well as a complete rotary motion can perform. As a result, the position of the tapping opening also shifts: 4. It can several tapping openings can also be provided. Arise at the tapping point Gas plumes, which represent a very unpleasant annoyance for the operators. On the one hand to be able to draw off these gases at the respective tapping point, on the other hand but avoiding the intake of secondary air at all other places is an annular one Channel 5 is provided, the lower part 5a of which can be rotated or pivoted with the furnace pan i and whose upper part 5b is fixed and connected to one or more flue pipes 6 is. Between the two parts of the annular channel there are seals 7, for. B. liquid seals or so-called sand cups. -CTT over each tapping point 4 an opening 8 is made in the bottom of the part 5a, so that the gases in the channel 5 can violate. A screen 9 directs the gases to this transition point. The invention thus offers the possibility of the swath at any point without to be able to draw off large amounts of secondary air, in such a way that this results in the superstructures not be disturbed on the furnace lid. So you are in the arrangement of the filling shafts ii and the electrodes r2 including their seals completely free.

Der Kanal 5 kann statt rechteckig auch rund ausgebildet werden, Die Dichtungen 7 können auch in verschiedener Höhenlage angeordnet sein. Sofern der Ofen nur in einem begrenzten.Bereich schwenkt, kann es genügen, wenn der Kanal 5 nicht einen vollständigen Kreisring bildet wie im Ausführungsbeispiel, sondern nur einen Kreisbogen umfaßt, welcher -etwa dem Schwenkbereich der Abstichschnauze entspricht.The channel 5 can also be formed round instead of rectangular, the Seals 7 can also be arranged at different heights. Unless the If the furnace only swivels in a limited range, it may be sufficient if channel 5 does not form a complete circular ring as in the exemplary embodiment, but only comprises an arc of a circle which -approximately corresponds to the pivoting range of the tapping nose.
