Description
Vorrichtung zum Brennen von keramischen FliesenDevice for firing ceramic tiles
Die Erfindung betrifft die Weiterentwicklung einer Vorrichtung gemäß P 32 17 076.9 sowie die Ausbildung einer zum Brennen in einer derartigen Vorrichtung geeigneten keramischen Fliege.The invention relates to the further development of a device according to P 32 17 076.9 and the training a ceramic fly suitable for firing in such a device.
Bei der Vorrichtung gemäß P 32 17 076.9 werden die zu brennenden keramischen Fliesen mittels Auflageelementen durch den Ofen transportiert, die als langgestreckte Auflageprofile ausgebildet sind, quer zur Transportrichtung einen lichten Abstand voneinander aufweisen und sich auf teilweise angetriebenen, rotierenden Tragelementen abstützen.In the device according to P 32 17 076.9, the ceramic tiles to be fired are placed by means of support elements transported through the furnace, which are designed as elongated support profiles, have a clear distance from each other transversely to the transport direction and are based on partially driven, support rotating support elements.
Da die Fliesen hierbei nur mit einem sehr geringen Teil ihrer Grundfläche auf den Auflageelementen aufliegen, ist ein guter Zutritt des Heizmediums auch zur Unterseite der Fliesen gewährleistet. Dadurch wird die Aufheizung der Fliesen vergleichmäßigt und beschleunigt, was sich sowohl, auf die Qualität der Wärmebehandlung, als auch auf die Durchlaufzeit und den Energieverbrauch günstig auswirkt.Since the tiles here only have a very small part of their base area on the support elements are on top, good access of the heating medium to the underside of the tiles is guaranteed. As a result, the heating of the tiles is evened out and accelerated, which affects both the The quality of the heat treatment as well as the lead time and energy consumption are favorable affects.
Ein weiterer Vorteil der Vorrichtung gemäß P 32 17 076.9 besteht darin, daß die Zahl der ortsfest angeordneten, zumindest teilweise angetriebenen rotierenden Tragelemente, auf denen sich die Auflageelemente abstützen, im Vergleich zum Stand der Technik wesentlich verringert werden kann, was eine beachtliche Senkung der Anlagekosten mit sich bringt.Another advantage of the device according to P 32 17 076.9 is that the number of Stationary, at least partially driven rotating support elements on which the support elements are supported, can be significantly reduced compared to the prior art can, which brings with it a considerable reduction in investment costs.
Der Erfindung liegt nun die Aufgabe zugrunde, die Vorrichtung entsprechend dem Hauptpatent sowie die zum Brennen in dieser Vorrichtung bestimmten Fliesen so auszubilden, daß sich·eine wesentliche Vereinfachung der Einrichtungen zur Führung der Auflageelemente in Transportrichtung ergibt.The invention is based on the object, the device according to the main patent and the to design tiles intended for firing in this device in such a way that there is a substantial simplification the means for guiding the support elements in the transport direction results.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1.
Der Erfindung liegt die Erkenntnis zugrunde, daß es genügt, im Bereich auf der Eintritts- und Austrittsseite des Ofens die noch nicht bzw. nicht mehr mit Fliesen belegten Auflageelemente durch ortsfeste Führungselemente in Transportrichtung zu führen, während im Bereich des Ofens eine ausreichende Führung der Auflageelemente durch die Fliesen selbst erfolgen kann. Die Fliesen sind zu diesem Zweck erfindungsgemäß an ihrer Unterseite mit einer Profilierung· versehen, in die wenigstens zwei parallel zueinander verlaufende Auflageelemente eingreifen.The invention is based on the knowledge that it is sufficient in the area on the entry and exit sides of the furnace through the support elements that are not yet or no longer covered with tiles To guide stationary guide elements in the transport direction, while in the area of the furnace a sufficient The support elements can be guided through the tiles themselves. The tiles are too For this purpose, according to the invention, provided on their underside with a profile in which at least engage two mutually parallel support elements.
Bei den der Erfindung zugrundeliegenden eingehenden Versuchen hat sich herausgestellt, daß es zur Erzielung der notwendigen Führung der Auflageelemente in Transportrichtung genügt, wenn jeweils zwei benachbarte Auflageelemente durch die auf ihnen lastenden Fliesen, in deren an der Fliesenunterseite vorgesehene Profilierung sie eingreifen, exakt parallel zueinander geführt sind. Auf diese Weise laufen alle zu einer Gruppe benachbarter Auf-In the detailed tests on which the invention is based, it has been found that it is necessary to achieve the necessary guidance of the support elements in the transport direction is sufficient if two adjacent Support elements through the tiles that weigh on them, in those on the underside of the tile provided profiling they intervene, are guided exactly parallel to each other. To this Wise, they all run to a group of neighboring

Indem bei der erfindungsgemaßen Lösung im Bereich des Ofens die Führung der Auflageelemente ausschließlich durch die auf ihnen lastenden Fliesen selbst erfolgt, ergibt sich eine wesentliche Vereinfachung der im Ofen unterzubringenden, teilweise angetriebenen rotierenden Tragelemente. Es ist insbesondere nicht erforderlich, diese im Ofen vorzusehenden rotierenden Tragelemente mit Führungsrillen, Führungsprofilen oder dgl. auszubilden. In that, in the solution according to the invention, in the area of the furnace, the support elements are exclusively guided takes place through the tiles themselves bearing down on them, there is a significant simplification the partially driven rotating support elements to be accommodated in the furnace. It is particular it is not necessary to design these rotating support elements to be provided in the furnace with guide grooves, guide profiles or the like.
Es können vielmehr über die gesamte Ofenlänge einfache, glattzylindrische Rollen Verwendung finden, was den Einsatz einfacher ausgebildeter Rollen von geringerer Stärke mit kleinerer Oberfläche und geringerer Korrosion gestattet. Außer der hierdurch erzielten Verringerung·der Herstellungskosten ergeben sich weiterhin beachtliche betriebliche Vorteile durch die geringere Verschmutzungs- und Verschleißanfälligkeit der glattzylxndrischen Rollen, was die Wartung der Anlage erheblich vereinfacht.Rather, simple, smooth cylindrical rollers can be used over the entire length of the furnace, what the use of simple trained rollers of lesser strength with smaller surface and less corrosion allowed. In addition to the resulting reduction in manufacturing costs There are still considerable operational advantages due to the lower susceptibility to soiling and wear the smooth-cylindrical rollers, which considerably simplifies the maintenance of the system.
Die an der Unterseite der Fliesen vorgesehene Profilierung wird zweckmäßig so ausgebildet, daß die stabförmigen Auflageelemente ein gewisses Spiel haben, das einen Ausgleich ihrer Unglexchmäßxgkeiten im Ofen ermöglicht. Wie die der Erfindung zugrundeliegenden, eingehenden Versuche zeigten, wird durch ein solches begrenztes Spiel der Auflageelemente inThe profiling provided on the underside of the tiles is expediently designed so that the rod-shaped support elements have a certain amount of play that compensates for their inaccuracies in the oven. As the invention on which the invention is based, In-depth tests showed that such a limited play of the support elements in

Eine die korrekte Führung der Auflageelemente in Transportrichtung beeinträchtigende Richtungsänderung könnte nämlich im wesentlichen nur durch eine^ Drehung der Auflageelemente um ihre Achse erfolgen, die jedoch durch das Gewicht der auf den Auflageelementen lastenden Fliesen in Verbindung mit der auf der Unterseite vorgesehenen Profilierung verhindert wird.the profiling provided on the underside of the tiles, the longitudinal guidance of the support elements not affected. An impairment of the correct guidance of the support elements in the transport direction A change in direction could essentially only be achieved by rotating the support elements take place around their axis, but this is due to the weight of the load on the support elements Tiles in connection with the profiling provided on the underside is prevented.

Im Bereich auf der Eintrittsseite des Ofens und ebenso im Bereich auf der Austrittsseite des Ofens sind die noch nicht bzw. nicht mehr mit Fliesen belegten Auflageelemente 2 durch ortsfeste Führungselemente in Transportrichtung geführt. Diese Führungselemente können - wie im Hauptpatent im einzelnen dargelegt ist - beispielsweise durch Führungsrollen oder Führungsschienen gebildet werden, an denen die Auflageelemente 2 entlanggleiten. Diese Führungsprofile können dabei auch Bestandteil der rotierenden Tragelemente sein, auf denen sich die Auflageelemente 2 abstützen.In the area on the inlet side of the furnace and also in the area on the outlet side of the furnace are the support elements 2 not yet or no longer covered with tiles by stationary guide elements guided in the transport direction. These guide elements can - as in the main patent im is set out individually - formed for example by guide rollers or guide rails on which the support elements 2 slide along. These guide profiles can also Be part of the rotating support elements on which the support elements 2 are supported.
Im Bereich des Ofens erfolgt demgegenüber die Führung der Auflageelemente 2 in Transportrichtung ausschließlich durch die auf den Auflageelementen 2 lastenden Fliesen 1. Zu diesem Zweck ist an der Unterseite der Fliesen 1 eine Profilierung vorgesehen, für die Fig. 1 ein Beispiel zeigt. 30In the area of the furnace, on the other hand, the support elements 2 are guided in the direction of transport exclusively through the tiles 1 bearing on the support elements 2.

beachten, daß in bestimmten Zonen des Ofens ein großer Temperaturgradient in Längsrichtung besteht, der zu einem Temperaturunterschied von bis zu 3000C zwischen Stabanfang und Stabende führen kann. Um unerwünscht große Temperaturdifferenzen zwischen den Auflageelementen und den daraufliegenden Fliesen zu vermeiden, muß die Stablänge begrenzt werden, und zwar um so mehr, je schneller das Brenngut durch den Ofen gefahren wird und je größer der im Ofen vorhandene Temperaturgradient ist.Note that in certain zones of the furnace a large temperature gradient in the longitudinal direction is, which can lead to a temperature difference of up to 300 0 C between the bar start and bar end. In order to avoid undesirably large temperature differences between the support elements and the tiles lying on it, the rod length must be limited, the more the faster the kiln is driven through the furnace and the greater the temperature gradient present in the furnace.
