Description
Einrichtung zum Abdichten des Glührauins von GlÜhöfen. Bei elektrischen Glühöfen, insbegondere Bjankglüh,öfen, die mit einem Schutzgas gefüllt werden, ist es notwendig, den Ofen gasdichtgbzuschließen. Bei:Schacht,-oderMuffel. öfen kann man eine Dichtung mittels Öltasse erzielen, doch läßt sich eine solche Anordnung bei öfen mit ausfahrbarern Herd oder Wagen nicht anbringen.Device for sealing the Glührauins from GlÜhöfen. With electrical Annealing furnaces, especially Bjankglüh, furnaces that are filled with a protective gas it is necessary to close the furnace gas-tight. At: shaft or muffle. ovens You can achieve a seal by means of an oil cup, but such an arrangement can be Do not attach to ovens with retractable stoves or trolleys.
Gegenstand der Erfindung ist eine Einrichtung, die auch solche öfen abzudichten gestattet, die an 'der Vorderseite oder auch an der Rückseite mit einer Tür versehen sind. Die öf en werden dadurch abgedichtet, daß zwischen Ofen- und Türummantelung ein Schlauch eingelegt wird, der, solange der Ofen geschlossen ist, mit Luft gefüllt gehalten wird. Durch diese pneumatische Dichtung ist es möglich, einen vollständig gasdichten Abschluß zu -erzielen. Der Luftschlauch wird zweckmäßig an einer möglichst kühlen 'Stelle der Ofenummantelung angeordnet. Um. ihn jedoch schädlichen Wärmeeinflüssen zu entziehen, kann man die Teile des Ofens, mit denen der Schlauch in Berührung kommt, mit einer Wasserkühlung versehen, In der Abbildung ist ein Ausführungsbeispiel der Erfindung dargestellt. Mit a ist das Innere des Ofens bezeichnet, mit b die Ummantelung der Ofentür und mit c die Ausmauerung der Ofentür. Art der Stelled, an der sich der Deckel gegen die Ummantelung und Ausmauerung des Ofens anlegt, sind Ofen-und TürununantelÜng mit einer umlaufenden, aufeinander passenden Dichtungsrille versehen, in der der Luftschlauch e liegt. f ist die Druckluft- oder 'Preßgaszuführung zu dem Dichtungsschlauch, g die Wasserkühlung in der Metallummantelung des Ofens und li die Wasserzuführung. 'Man kann aujh in der Metallummantelung b der Tür eine Wasserkühlung entsprechend der für das Ofengehäuse dargestellten anordnen.The subject of the invention is a device which allows to seal also those ovens which are provided with a door on the front or on the back. The ovens are sealed by inserting a hose between the oven and door casing which, as long as the oven is closed, is kept filled with air. This pneumatic seal makes it possible to achieve a completely gas-tight seal. The air hose is expediently arranged at a point on the furnace jacket that is as cool as possible. Around. However, to remove it from harmful heat influences, the parts of the furnace with which the hose comes into contact can be provided with water cooling. In the figure, an embodiment of the invention is shown. The interior of the furnace is designated with a, the casing of the furnace door with b and the lining of the furnace door with c. The type of position at which the cover rests against the casing and brick lining of the oven, oven and door casing are provided with a circumferential, matching sealing groove in which the air hose e lies. f is the compressed air or compressed gas supply to the sealing hose, g the water cooling in the metal casing of the furnace and li the water supply. You can also arrange a water cooling system in the metal casing b of the door corresponding to that shown for the furnace housing.
Der eingelegte Luftschlauch e kann dauernd von außen unter Druck gehalten oder nach Art eines Fahrradschlauches aufgepumpt werden.The inserted air hose e can be kept permanently under pressure from the outside or be inflated like a bicycle tube.
Der Luftschlauch kann mehrkammrig ausgeführt werden, um beispielsweise beim Ver-,sagen der einen Kammer die andere in Tätigkilt setzen zu können.The air hose can be designed with multiple chambers, for example if one chamber fails to be able to put the other into action.
