Description

Tunnelofen, besonders zum Brennen von Emailwaren. Die vorliegende Erfindung #bezieht sich auf Tunnelofen besonders für Emailwaren, und zwar sowohl auf solche von geradliniger als von runder Bauart, und bezAveckt, (diie aus der Strahlung in -der Zone,der hohen Temperatur herrühren-dien Verluste auf ein Mindestmaß zu beschränken ohne einen Temperaturabfall bziv. Tempeiatursturz bei der Bieweggung der Gasmasse ausder Abkühllungszone in die Anwärmezone, obwohl diese beiden Zonen voneinander durch dJie Brennzone, d. i. die Zone derhohen Temperatur, getrennt sind.Tunnel kiln, especially for firing enamel goods. The present invention relates to tunnel kilns, especially for enamel goods, both to those of a straight as well as of a round design, and referenced, (which result from the radiation in the zone, the high temperature - the losses to a minimum without restricting a temperature drop or fall in temperature when the gas mass moves from the cooling zone into the heating zone, although these two zones are separated from one another by the burning zone, i.e. the zone of high temperature.

Bei vorliegender Erfindung ist (was an sich bekannt ist) der eigentliche Tunne.lofen da, wo ;sich Idas, Brennen bei hoher Temperatur vollzieht, von einem Manteltunnel umgeben, Üerart, ;daß zwischen beiden Tunneln ein leerer Raum gebildet wird, in welchem eine Gasinasse mit geringerer Temperatur als der Brenntemperatur zirkliert, welche aus der Abkühlungszone kommt, um in i-die Anwärmezone zu gelangen.In the present invention (which is known per se) is the real one Tunne.lofen where; Idas, burning at high temperature takes place, from one Manteltunnel surround, Üerart, that an empty space was formed between the two tunnels becomes, in which a gas mass with a lower temperature than the firing temperature circulates, which comes from the cooling zone to get into i-the heating zone.

Der innere Tunnel ist mit Isoliermasse belegt, welche,derart geregelt werden kann, daß die durch äußere Strahlung in Odem Manteltunnel verlorene Wärme annähernd der durch den inneren Tunnel übertragenen entspricht. Durch diese Anordnung kann das Gasgemisch aus der Abkühlungszone in idie Anwärmezone ohne Temperatursturz gelangen, und der Strahlungsverlust #'durch äußere Strahlung wird iauf ein Maß herabgesetzt, wie es bei einem Ofen der Fall wäre, dessen Brenntemperatur einige hundert Grade geringer wäre. Um #die Menge (des angesaugten,Gases im Manteltunnel zu regeln, ist zwischen der Schmelzzone un-d Ader Anwärmezone ein Schieber vorgesehen. Am Ausgang des Manteltunnels können idie Gase mit dem aus dem inneren Tunnelofen kommenden gemischt werden.The inner tunnel is covered with insulating material, which is regulated in this way can be that the heat lost by external radiation in the jacket tunnel breath approximately corresponds to that transmitted through the inner tunnel. Through this arrangement the gas mixture can move from the cooling zone into the heating zone without a drop in temperature reach, and the radiation loss # 'by external radiation is reduced to a level as would be the case with a furnace, the temperature of which is a few hundred degrees would be less. To # regulate the amount (of the gas sucked in in the jacket tunnel A slide is provided between the melting zone and the heating zone. At the exit of the jacket tunnel, the gases can be mixed with the one coming from the inner tunnel furnace be mixed.

Die Zeichnung zeigt in Abb. i und .2 den Längsschnitt und einen Querschnitt nach der Linie A-B einer beispieliweisen Ausführungsform.The drawing shows in Fig. I and .2 the longitudinal section and a cross section according to the line A-B of an exemplary embodiment.

Der Tunnel i, in welchem das Brennen vor sich geht und in welchem -die Wiagenteile 2, sich bewegen, die mit den zu behandelnden Gegenständen versehen sind, ist von einem .Nlantcl 3 umgeben, derart, daß zwischen beiden Tunneln ein freier Raum 4 verbleibt, in welchem die -,varme Luft zirkuliert, die zum Abkühlen der gebrahnten Waren gedient hat. Die Luft tritt bei 5 ein und kehrt bei 6 in die Anwärmezone zurück, wo sie sdchmit den Verbrennungsproidukten mischt.The tunnel i, in which the burning takes place and in which the carriage parts 2 move, which are provided with the objects to be treated, is surrounded by a .Nlantcl 3 , such that a free space 4 remains between the two tunnels in which the hot air circulates, which was used to cool the fired goods. The air enters at 5 and returns to the heating zone at 6 , where it mixes with the combustion products.

Bei 7 -ist 'die Isoliermasse eingebracht, welche aus Sand oder gleichwertig= Stoff besteht, der an iden gewünschten Stellen ,durch öffnungen 8 eingeschüttet werden kann, und dessen Stärkt und Menge infolge der Öffnungen 8 beliebig geregelt werden ,kann, welche durch Deckel 9 abschließbar sind.At 7, the insulating compound is introduced, which consists of sand or equivalent = substance that can be poured in at the desired locations through openings 8 , and the strength and quantity of which can be regulated as desired as a result of the openings 8 , which can be controlled by cover 9 are lockable.

PATENT-ANSPRUCH: Tunnelofen - besonders zum Brennen von Emailwaren, bei welchem die Zone, wo sich Idas Brennen -vollzieht, von einem zweiten Tunnel umgeben ist, ;derart, daß zwischen beiden Tunneln ein freier Raum entsteht, in welchem,die Gase zirkulieren, die zum Abkühlen der gebrannten Waren geffient haben und aus der Abkühlzone in .die Anwärmezone gehen, dadurch gekennzeichnet, daß der innere Tunnel mit isolierenden Stoffen belegt ist, der-en Menge und Stärke entsprechend. ider Tsolierung des Tunnelmantels regelbar ist behufs Vermeidung eines Temperatursturzes der heißen Gase bei der Zirkulation derselben in idem Manteltunnel von der Abkühlzone nach der Anwärmezone.PATENT CLAIM: Tunnel kiln - especially for firing enamel goods, in which the zone where Ida's firing takes place is surrounded by a second tunnel; in such a way that a free space is created between the two tunnels in which the gases circulate, who have opened for the cooling of the fired goods and go out of the cooling zone into .die warming zone, characterized in that the inner tunnel is covered with insulating materials, the amount and thickness corresponding to that. The insulation of the tunnel jacket can be regulated in order to avoid a drop in temperature of the hot gases when they circulate in the jacket tunnel from the cooling zone to the heating zone.
