Description

Tunnelofen, in dessen Gas- und/oder Luftzuleitungen Ultraschallgeber angeordnet sind Zusatz zum Patent 952533 Nach dem Hauptpatent 952 333 werden Ultraschallgeber bei Tunnelöfen zur Verbesserung des Temperaturausgleichs verwendet.Tunnel furnace with an ultrasonic generator in its gas and / or air supply lines are arranged addendum to patent 952533 According to the main patent 952 333 ultrasonic transducers are used in tunnel ovens to improve temperature equalization.

Der vorliegenden Erfindung liegt das Problem zugrunde, das Temperaturgefälle zwischen den Ofenenden und der Außenluft, welches auch bei den praktisch bestmöglichsten Endverschlüssen der Tunnelöfen vorhanden ist, möglichst zu vermeiden oder unschädlich zu machen. The present invention is based on the problem, the temperature gradient between the furnace ends and the outside air, which is also practically the best possible Terminations of the tunnel kilns are available, to be avoided or harmless if possible close.

Das soll nun gemäß der Zusatzerfindung durch Beschallung der Ofengase im Bereich der Ofenenden erzielt werden. Die thermodynamischen Bedingungen sind im Bereich der Ofenenden insofern von denen des übrigen Tunnelinhalts verschieden, als ohne Ultraschalleinflüsse wenig Wärmezufuhr und dabei unter Einwirkung der Außentemperatur Wärmeabfuhr stattfinden würde. Wärmezu- und -abfuhr würden sich mehr oder minder ausgleichen, aber es würde das Ergebnis eine allgemeine tiefere Durchschnittstemperatur im Vergleich zum Ofeninnern sein. Es wurde nun gefunden, daß die Anwendung des Beschallens im Bereich der Ofenenden eine zweckmäßige Vervollkommnung des Gegenstands des Hauptpatents darstellt. According to the additional invention, this should now be done by exposing the furnace gases to sound can be achieved in the area of the furnace ends. The thermodynamic conditions are in the area of the furnace ends different from those of the rest of the tunnel content, than without the influence of ultrasound, little heat input and at the same time under the influence of the outside temperature Heat dissipation would take place. Heat supply and removal would be more or less balance, but it would result in an overall lower average temperature compared to the inside of the stove. It has now been found that the application of sonication in the area of the furnace ends an expedient improvement of the subject matter of the main patent represents.

Nach der Erfindung kann man mehrere Schallgeber unmittelbar vor dem Ein- und Ausfahrtsende des Tunnelofens nach der Seite oder nach oben umklappbar anbringen, um das Ein- bzw. Ausfahren der Brennwagen zu ermöglichen. Es können auch entsprechend starke Schallgeber hinter der Schiebebühne sowie an der Seite und am Gewölbe fest in einer Weise angeordnet werden, daß die ein- und oder ausfahrenden Brennwagen von allen Seiten beschallt werden. According to the invention you can have several sounders immediately before The entry and exit end of the tunnel oven can be folded to the side or upwards to enable the trolleys to be moved in and out. It can too correspondingly strong sounders behind the transfer table as well as on the side and on the Vaults are firmly arranged in such a way that the entering and exiting Brennwagen can be exposed to sound from all sides.
