Description
Einetagen-Flachbahntrockner für Furniere Die Erfindung betrifft einen Einetagen-Flachbahntrockner für Furniere mit senkrecht oder nahezu senkrecht zu den Furnierflächen von oben und unten zugeführter Heiß- oder Warmluft. Ihr liegt die Aufgabe zugrunde, die schnelle Trocknung eines Furniers durch düsenartige Luftbeaufschlagung zu erzielen, ohne daß das Furnier wellig wird oder Markierungen erhält und ohne daß Düsenkörper erforderlich sind.Single-deck flat web dryer for veneers The invention relates to a Single-deck flat belt dryer for veneers with perpendicular or almost perpendicular to Hot or warm air supplied to the veneer surfaces from above and below. Her lies the underlying task is the rapid drying of a veneer by means of a nozzle-like application of air can be achieved without the veneer becoming wavy or marked and without that nozzle bodies are required.
Gemäß der Erfindung ist der Einetagen-Flachbahntrockner so ausgebildet, daß die Fördervorrichtung für das Furnier aus zwei parallel zueinander angeordneten Reihen von unmittelbar nebeneinander liegenden Scheibenwalzen gebildet wird, deren Scheiben quer zur Förderrichtung mindestens innerhalb von Gruppen von Scheibenwalzen gegeneinander versetzt sind, und daß zwischen Gruppen von Scheibenwalzen je ein Paar volle, sich über die gesamte Bahnbreite erstreckende Walzen vorgesehen ist.According to the invention, the single-deck flat web dryer is designed in such a way that that the conveyor for the veneer consists of two parallel to each other Rows of directly adjacent disc rollers is formed, whose Discs transverse to the conveying direction at least within groups of disc rollers are offset from one another, and that between groups of disc rollers each one Pair of full, over the entire web width extending rollers is provided.
Das Welligwerden des Furniers wird durch die unmittelbar aufeinanderfolgende Anordnung der Scheibenwalzen nebeneinander verhindert, wobei jeweils nur eine punktförmige Berührung zwischen Scheiben und dem Furnier erfolgt. Soweit die Scheiben geringfügige Markierungen auf dem Furnier hinterlassen, werden diese durch die zwischengeschalteten vollen Walzen wieder ausgeglichen. Durch die Nebeneinanderanordnung der Scheibenwalzen wird der Luftzuführungsquerschnitt verringert, so daß eine Zuströmgeschwindigkeit ähnlich wie bei bekannten Düsentrocknern erzielt wird, ohne daß besondere Düsenkörper notwendig sind. Durch diese Beaufschlagung wird eine intensive und schnelle Wärmeeinwirkung auf das Gut erzielt, die bei Furnieren bis zum Furnierkern reicht. Entsprechend wird auch eine schnellere Wasserverdunstung und Trocknung des Furniers ohne erhöhten Wärmeaufwand sowie eine Verbesserung der Eigenschaften und des Aussehens von Furnieren, insbesondere ein einwandfreies Flachbleiben derselben, erzielt.The waviness of the veneer is caused by the consecutive Prevents the arrangement of the disc rollers side by side, with only one punctiform in each case There is contact between the panes and the veneer. As far as the slices are minor Marks left on the veneer are made by the intermediary full rollers balanced again. Due to the side by side arrangement of the disc rollers the air supply cross-section is reduced, so that an inflow velocity is achieved similarly to known nozzle dryers without the need for special nozzle bodies are necessary. This exposure results in an intensive and rapid heat effect on the material, which in the case of veneers extends to the veneer core. Corresponding will also allow faster water evaporation and drying of the veneer without increased Heat consumption and an improvement in the properties and appearance of veneers, in particular a perfect flatness of the same is achieved.
Vorzugsweise wird die Anordnung so getroffen, daß die Fördervorrichtung auf wenigstens 2 m Länge zwei Paar volle Walzen aufweist.Preferably, the arrangement is made so that the conveyor has two pairs of full rollers over a length of at least 2 m.
In der Zeichnung sind Ausführungsformen des neuen Trockners dargestellt. Es zeigen Fig. 1 und 2 zwei lediglich hinsichtlich der Anordnung der Lüfter unterschiedliche Ausführungsformen, und zwar Innenansichten quer zur Förderrichtung gesehen, Fig.3 eine Draufsicht auf einen Teil der Fördervorrichtung.In the drawing, embodiments of the new dryer are shown. 1 and 2 show two different only with regard to the arrangement of the fans Embodiments, namely interior views seen transversely to the conveying direction, Fig.3 a plan view of part of the conveyor.
Der neue Trockner besteht, je nach den Erfordernissen, aus mehreren Feldern, von denen je eines in den Fig. 1 und 2 dargestellt ist.The new dryer consists of several, depending on the requirements Fields, one of which is shown in FIGS. 1 and 2.
In einem tunnelartigen Gehäuse 1 ist die Fördervorrichtung für das Furnier angeordnet, die im wesentlichen aus zwei Schichten an sich bekannter Scheibenwalzen 2 besteht, die in an sich bekannter Weise gelagert sind und angetrieben werden. In gewissen Abständen zwischen den Scheibenwalzen 2 sind Paare von ebenfalls angetriebenen Walzen 3 mit vollem Mantel angeordnet.In a tunnel-like housing 1 is the conveyor for the Arranged veneer, which consists essentially of two layers of disc rollers known per se 2, which are stored and driven in a manner known per se. At certain intervals between the disk rollers 2 there are also driven pairs Rollers 3 arranged with a full jacket.
Zwischen den Paaren von Walzen 2 und 3 wird das Furnier 4 hindurchbewegt. Die Scheiben 2' der Scheibenwalzen 2 sind, wie insbesondere aus Fig. 3 hervorgeht, mindestens innerhalb einer Gruppe von Walzen 2, beispielsweise einer Gruppe, die durch volle Walzen 3 von benachbarten Scheibenwalzen 2 getrennt wird, gegeneinander versetzt, damit keine Streifenbildung an dem Furnier auftritt.The veneer 4 is moved through between the pairs of rollers 2 and 3. The disks 2 'of the disk rollers 2 are, as can be seen in particular from FIG. 3, at least within a group of rollers 2, for example a group that is separated from adjacent disc rollers 2 by full rollers 3, against each other offset so that no streaking occurs on the veneer.
Wie aus den Fig. 1 und 2 hervorgeht, sind innerhalb der Gehäuse 1, oberhalb und unterhalb der Fördervorrichtung, besondere Räume 5 (Fig. 1) und 6 (Fig. 2) vorgesehen, die im wesentlichen durch Trennwände 5' bzw. 6' gebildet werden.As can be seen from Figs. 1 and 2, are within the housing 1, above and below the conveyor, special rooms 5 (Fig. 1) and 6 (Fig. 2) provided, which are essentially formed by partition walls 5 'and 6'.
Nach Fig. 1 weisen die Trennwände 5' in ihrem lotrechten Teil Öffnungen für Lüfter 7, deren Wellen waagerecht angeordnet sind, auf. Die Wände 5' weisen ferner zwischen ihren waagerechten Teilen zur Hindurchführung der aus den Walzen 2 und 3 bestehenden Fördervorrichtung Öffnungen 8 auf.According to Fig. 1, the partition walls 5 'have openings in their vertical part for fans 7, the shafts of which are arranged horizontally, on. The walls 5 'have also between its horizontal parts for the passage of the rollers 2 and 3 existing conveyor device openings 8.
Die von den Lüftern 7 aus dem Gehäuse 1 angesaugte Luft wird in senkrechter Richtung, wie es die Pfeile andeuten, auf das durch die Fördervorrichtung geförderte Furnier 4 aufgeblasen, wobei die Luft, bevor sie mit dem Furnier 4 in Berührung kommt, durch oberhalb und unterhalb der Fördervorrichtung angeordnete Heizregister 9 streicht. Die auf das Furnier aufgeblasene Luft entweicht aus den Räumen 5 durch die Öffnungen 8 wieder in das Gehäuse 1, von wo sie wiederum von den Lüftern 7 angesaugt wird.The air sucked in from the housing 1 by the fans 7 becomes vertical Direction, as indicated by the arrows, to the conveyed by the conveyor Veneer 4 is inflated, the air being in contact with the veneer 4 before it comes through heating registers arranged above and below the conveyor 9 deletes. The air blown onto the veneer escapes from the spaces 5 through the openings 8 back into the housing 1, from where they turn from the fans 7 is sucked in.
Bei der Ausführungsform gemäß Fig.2 ist die Wirkungsweise dieselbe, jedoch mit dem Unterschied, daß in den Wänden der Räume 6 Lüfter 10 mit lotrecht angeordneter Welle vorgesehen sind.In the embodiment according to Figure 2, the mode of operation is the same, but with the difference that in the walls of the rooms 6 fans 10 with perpendicular arranged shaft are provided.
