Beschreibungdescription
Die Erfindung betrifft eine Fördervorrichtung für mit Wärme zu behandelnde Materialien in Tunnelöfen.The invention relates to a conveying device for to be treated with heat Materials in tunnel kilns.
Es sind bereits Transportvorrichtungen zum Befördern von mit Wärme zu behandelnden Materialien in Tunnelöfen bekannt. Diese Vorrichtungen haben ein hohes Gewicht und benötigen spezielle Einrichtungen oder Körbe aus feuerfestem Material. Die Verwendung solcher Transportvorrichtungen in Tunnelöfen führt zu beträchtlichen Wärmeverlusten und infolgedessen zu einem erhöhten Verbrauch an Energie, die zum Erwärmen der Vorrichtung und der beförderten mit Wärme zu behandelnden Materialien notwendig ist. Eine Rekuperation der aus dem Ofenraum derart entweichenden Wärme ist kostspielig. Die Rekuperationsanlage erfordert außerdem viel Raum Bei Band- und Kettenförderern für die mit Wärme zu behandelnden Materialien in Tunnelöfen ist die große Berührungsfläche nachteilig. Rollgänge allein eignen sich nicht besonders zum direkten Transport von z. B.There are already transport devices for moving with heat materials to be treated in tunnel kilns are known. These devices have a heavy and require special equipment or baskets made of refractory material. The use of such transport devices in tunnel kilns leads to considerable Heat loss and, as a result, an increased consumption of energy that is used for the Heating the device and the conveyed materials to be heat treated necessary is. A recuperation of the heat escaping from the furnace chamber in this way is costly. The recuperation system also requires a lot of space. and chain conveyors for the materials to be heat treated in tunnel kilns the large contact area is disadvantageous. Roller tables alone are not particularly suitable for the direct transport of z. B.
geringeren Produktmengen oder von großen Mengen von mit Wärme zu behandelnden Materialien auf einmal, da sie einen kontinuierlichen Transport nicht gewährleisten können und sich dabei Materialverschiebungen und dadurch bedingt Materialanhäufungen und -umgruppierungen ergeben. Die Mechanisierung der Entnahme der behandelten Materialien am Austritt des Tunnelofens ist in diesem Falle eine technisch sehr komplizierte und aufwendige Maßnahme.small amounts of product or large amounts of heat to be treated Materials at once, as they do not guarantee continuous transport can and thereby material displacements and, as a result, material accumulations and regrouping results. The mechanization of the removal of the treated materials at the exit of the tunnel kiln is a technically very complicated one in this case and complex measure.
Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile der bekannten Fördervorrichtungen von mit Wärme zu behandelnden Materialien in Tunnelöfen durch Schaffung einer einfach gebauten, die Wärmeverluste wesentlich reduzierenden Fördereinrichtung der genannten Art zu beseitigen.The invention is based on these disadvantages of the known Conveyors of materials to be treated with heat in tunnel kilns Creation of a simply constructed conveyor system that significantly reduces heat losses of the type mentioned.
Diese Aufgabe wird erfindungsgemäß bei der Fördervorrichtung der eingangs genannten Art durch endlose Saiten beliebiger geometrischer Gestalt, welche entlang einer abgegrenzten Bahn zwischen einer Antriebswalze und einer angetriebenen Walze abrollen, durch einen Rollgang mit einem Antrieb und durch ein System von Spannrollen mit Stützrollen zur Erzielung einer permanenten Vorspannung der endlosen Seiten gelöst.According to the invention, this object is achieved in the case of the conveyor device of the introduction named type by endless strings of any geometric shape, which along a delimited Web between a drive roller and a driven one Roll off roller, through a roller table with a drive and through a system of Tension rollers with support rollers to achieve permanent pre-tensioning of the endless Pages solved.
Die erfindungsgemäße Fördervorrichtung hat den Vorteil eines einfachen Aufbaus, der ohne großen Aufwand herstellbar und wartbar ist. Ferner kann die aus dem Innenraum des Tunnelofens entweichende Wärme wesentlich herabgesetzt werden.The conveyor device according to the invention has the advantage of being simple Structure that can be manufactured and maintained without great effort. Furthermore, the The heat escaping from the interior of the tunnel furnace can be significantly reduced.
Wegen der geringen Masse und damit wegen der geringen Speicherfähigkeit der Fördervorrichtung wird der Wärmeverlust wesentlich herabgesetzt, was die Ökonomie des Tunnelofenbetriebs günstig beeinflußt.Because of the low mass and therefore because of the low storage capacity the conveying device, the heat loss is significantly reduced, which is the economy the tunnel kiln operation favorably influenced.
Das mit Wärme zu behandelnde Material kann ohne spezielle Vorrichtungen auf die Saiten gelegt werden, wobei die Berührungsflächen zwischen Förderer und Material verhältnismäßig gering sind, was zu einer vollkommenen und schnellen Durchwärmung des zu behandelnden Materials führt. Die Vorteile der erfindungsgemäßen Fördervorrichtung sind beispielsweise bei rascher Abkühlung von Glas urdKeramik besonders evident. Darüber hinaus erlaubt die Vorrichtung, vor allem beim Transport einer größeren Menge von kleineren Artikeln, eine technisch einfache Mechanisierung der Materialentnahme am Austritt des Tunnelofens.The material to be treated with heat can be processed without special devices placed on the strings, the contact surfaces between conveyor and Material are relatively small, resulting in complete and rapid heating of the material to be treated leads. The advantages of the conveyor device according to the invention are particularly evident when glass and ceramics cool down quickly. In addition, the device allows, especially when transporting a larger one Amount of smaller items, a technically simple mechanization of material removal at the exit of the tunnel furnace.
Die erfindungsgemäße Fördervorrichtung ist in allen Typen von Tunnelöfen zur Wärmebehandlung von metallischen und nichtmetallinen Materialien verwendbar. Anzahl und Länge der endlosen Saiten können der Breite und Länge des Tunnelofeninnenraumes angepaßt werden.The conveyor device according to the invention is in all types of tunnel kilns can be used for heat treatment of metallic and non-metallic materials. The number and length of the endless strings can match the width and length of the tunnel furnace interior be adjusted.
Anhand der Zeichnung, die schematisch eine Ausführungsform einer Fördervorrichtung zeigt, wird die Erfindung näher erläutert.Based on the drawing, which schematically shows an embodiment of a conveyor device shows, the invention is explained in more detail.
Die Fördervorrichtung hat endlose, sich entlang einer abgegrenzten Bahn zwischen einer Antriebswalze 1 und einer angetriebenen Walze 2 abrollende Saiten 7 sowie einen Rollgang 5 mit einem Antrieb. Ein System von Spannrollen 3 und 4 zusammen mit Stützrollen 6 gewährleistet eine permanente Vorspannung der endlosen Saiten 7.The conveyor has endless, moving along a demarcated Web between a drive roller 1 and a driven roller 2 unrolling strings 7 and a roller table 5 with a drive. A system of tension pulleys 3 and 4 together with support rollers 6 ensures permanent pretensioning of the endless strings 7th
