Description

Die Erfindung betrifft ein Bauelement aus Leichtmetall für Trocken- und Wärmebehandlungsvorrichtungen.The invention relates to a component made of light metal for drying and heat treatment devices.

Für Trocknungs- und Wärmebehandlungsprozesse sind unterschiedliche Vorrichtungen bekannt, deren Wände aus sog. strahlenden Armaturen aufgebaut sind. Die strahlenden Armaturen werden im allgemeinen an Trägerplatten und/oder Gerüstkonstruktionen befestigt und mit diesen beziehungsweise untereinander durch Schrauben verbunden.Different devices are known for drying and heat treatment processes, the walls of which are constructed from so-called radiating fittings. The radiating fittings are generally attached to support plates and / or scaffold structures and connected to them or to one another by screws.

Bei diesen Vorrichtungen müssen die Trägerplatten beziehungsweise Gerüstkonstruktion individuell konstruiert und hergestellt werden, und der Zusammenbau ist mit umständlichen Montagearbeiten verbunden. Nachteilig ist auch, daß sich die elektrischen Anschlußpunkte der strahlenden Armaturen direkt im beheizten Raum befinden und deshalb durch Installieren von Ventilatoren dafür gesorgt werden muß, daß sich die Anschlüsse nicht über 300°C erwärmen. Durch diesen Umstand werden Konstruktion und Montage noch komplizierter.With these devices, the carrier plates or scaffolding construction must be individually designed and manufactured, and the assembly is associated with cumbersome assembly work. Another disadvantage is that the electrical connection points of the radiating fittings are located directly in the heated room and therefore, by installing fans, it must be ensured that the connections do not heat up above 300 ° C. This makes construction and assembly even more complicated.

Es sind aber auch Kühlelemente bekannt (DE-A-2939852), die an zwei gegenüberliegenden Seitenrändern mit Zahnköpfen und Zahnlükken versehen sind, so daß die Zahnköpfe und Zahnlücken einander benachbarter Kühlelemente ineinandergreifen, um hierdurch die Wärmeableitung im Verbindungsbereich der Kühlelemente zu verbessern. Diese Kühlelemente sind zum Einbau in die Wand metallurgischer Öfen bestimmt und in der Einbaulage an dem Ofenpanzer abgestützt, wobei an der Rückseite der Bauelemente herausgeführte Anschlußelemente außerhalb des Ofenpanzers über Rohrbögen miteinander verbunden sind.However, cooling elements are also known (DE-A-2939852), which are provided on two opposite side edges with tooth heads and tooth gaps, so that the tooth heads and tooth gaps of mutually adjacent cooling elements mesh with one another, thereby improving the heat dissipation in the connection area of the cooling elements. These cooling elements are intended for installation in the wall of metallurgical furnaces and are supported in the installed position on the furnace shell, connection elements which are led out on the rear of the components being connected to one another outside the furnace shell via pipe elbows.

Aufgabe der Erfindung ist die Schaffung eines Bauelementes, mit dem Trocken- und Wärmebehandlungsvorrichtungen ohne Trägerplatten und/ oder Gerüstkonstruktionen erstellt werden können, das ferner nicht angeschraubt werden muß und auch eine Vereinfachung der Kühlung ermöglicht.The object of the invention is to provide a component with which dry and heat treatment devices can be created without carrier plates and / or scaffold structures, which furthermore does not have to be screwed on and also enables the cooling to be simplified.

Diese Aufgabe wird durch ein Bauelement zur Erstellung von Trocken- und Wärmebehandlungsvorrichtungen gelöst, das einen prismenförmigen Hohlkörper und ein den Hohlraum des Hohlkörpers mit dem Außenraum verbindendes Anschlußelement aufweist, das an der Rückseite des Hohlkörpers herausgeführt ist. Für das erfindungsgemäße Bauelement ist kennzeichnend, daß die beiden einander gegenüberliegenden, an die Rückseite des Hohlkörpers angrenzenden Seitenflächen als Formschluß-Verbindungsflächen ausgebildet sind, die zueinander komplementär gestaltet sind, indem an der einen Seitenfläche zwischen zwei in Längsrichtung des Hohlkörpers verlaufenden Rippen mit einem bogenförmigen Querschnittsprofil eine in Längsrichtung des Hohlkörpers verlaufende Formschlußrippe absteht, die einen an dem Hohlkörper ansetzenden Steg und einen gegenüber dem Steg verbreiterten Kopf aufweist, und indem an der anderen Seitenfläche zwei zu den Rippen komplementäre Rundnuten und eine zu der Formschlußrippe komplementäre hinterschnittene Formschlußnut ausgebildet sind.This object is achieved by a component for creating dry and heat treatment devices, which has a prism-shaped hollow body and a connecting element connecting the cavity of the hollow body to the outside, which is led out at the rear of the hollow body. It is characteristic of the component according to the invention that the two mutually opposite side surfaces adjoining the rear of the hollow body are designed as positive-locking connection surfaces which are designed to be complementary to one another by having on one side surface between two ribs running in the longitudinal direction of the hollow body with an arcuate cross-sectional profile a form-fitting rib extending in the longitudinal direction of the hollow body protrudes, which has a web that attaches to the hollow body and a head that is widened relative to the web, and that two round grooves complementary to the ribs and an undercut form-locking groove complementary to the form-locking rib are formed on the other side surface.

Es ist vorteilhaft, wenn die Seitenflächen parallel zueinander verlaufen oder einen zwischen 0° und 180° liegenden Winkel miteinander einschließen. Im letzeren Fall ist es zweckmäßig, wenn sich die Seitenflächen an der der Rückseite des Hohlkörpers gegenüberliegenden Seite in einer Kante treffen.It is advantageous if the side surfaces run parallel to one another or enclose an angle between 0 ° and 180 °. In the latter case, it is expedient if the side surfaces meet at an edge on the side opposite the back of the hollow body.

Bevorzugt ist es ferner, in der Wandung des Hohlkörpers wenigstens einen Kanal mit konstantem Querschnitt vorzusehen. Vorteilhaft ist es auch, wenn an der der Rückseite des Hohlkörpers gegenüberliegenden Vorderseite desselben eine sich zwischen den Seitenflächen erstreckende reflektierende Fläche vorgesehen ist, vor der sich ein Strahlungselement befindet. Schließlich ist es vorteilhaft, wenn der Hohlkörper an der dem Anschlußelement gegenüberliegenden Seite eine in den Hohlraum des Hohlkörpers mündende Öffnung aufweist.It is also preferred to provide at least one channel with a constant cross section in the wall of the hollow body. It is also advantageous if on the front side of the hollow body opposite the back of the hollow body there is a reflecting surface extending between the side surfaces, in front of which there is a radiation element. Finally, it is advantageous if the hollow body has on the side opposite the connecting element an opening opening into the hollow space of the hollow body.

Das in Fig.l dargestellte Bauelement hat einen prismenförmigen Hohlkörper 10 annähernd quadratischen Querschnittes; der Hohlkörper 10 wird zweckmäßig aus extrudiertem Aluminiumprofil hergestellt. Der Hohlkörper 10 hat in Längsrichtung einen inneren Hohlraum 12, der zur Führung der Kühlluft dient. An der in Fig. 1 die untere Seite (d.h. in Benutzungsstellung dieRückseite) bildenden Seite des Hohlkörpers 10 sind ein oder mehrere Anschlußelemente 14 angebracht, mit denen der Hohlraum 12 mit dem Außenraum beziehungsweise einer (nicht abgebildeten) Kühlvorrichtung in Verbindung steht.The component shown in Fig.l has a prismatic hollow body 10 of approximately square cross-section; the hollow body 10 is expediently made of extruded aluminum profile. The hollow body 10 has an inner cavity 12 in the longitudinal direction, which serves to guide the cooling air. On the side of the hollow body 10 which forms the lower side (i.e. the rear side in the use position) in FIG. 1, one or more connection elements 14 are attached, by means of which the hollow space 12 is connected to the outer space or to a cooling device (not shown).

An der in Fig. 1 oberen (in Benutzungsstellung vorderen) Seite des Hohlkörpers 10 ist aus einem spiegelnden Material (zum Beispiel aus Aluminiumblech) eine reflektierende Fläche 16 ausgebildet, vor welcher ein langgestrecktes Strahlungselement 18 vorgesehen ist (Konstruktion und Befestigung derartiger Strahlungselemente sind bekannt und gehören nicht zum Wesen der Erfindung, das Strahlungselement ist deshalb nur angedeutet). Das Profil des Hohlkörpers 10 wird so gewählt, daß von beiden Seiten (gemäß Fig. 1 die rechte und linke Seite) je ein Wulst 20 nach innen verläuft. Die gemäß Fig. 1 obere Seite der Wülste 20 weist eine der reflektierenden Fläche 16 angepaßte Wölbung auf, während die untere Seite abgeschrägt ist. Im Inneren der Wülste 20 ist in Längsrichtung je ein Kanal 22 kreisförmigen Querschnitts vorgesehen, der zur Leitung des Kühlwassers dient und mit einem (nicht dargestellten) Kühlsystem in Verbindung steht.On the upper side (in the use position) of the hollow body 10 in FIG. 1, a reflecting surface 16 is formed from a reflective material (for example from aluminum sheet), in front of which an elongated radiation element 18 is provided (construction and fastening of such radiation elements are known and do not belong to the essence of the invention, the radiation element is therefore only hinted at). The profile of the hollow body 10 is chosen so that from both sides (according to FIG. 1 the right and left side) a bead 20 extends inwards. The upper side of the beads 20 according to FIG. 1 has a curvature adapted to the reflecting surface 16, while the lower side is chamfered. In the interior of the beads 20, a channel 22 of circular cross section is provided in the longitudinal direction, which is used to guide the cooling water and is connected to a cooling system (not shown).

Die gemäß Fig. 1 rechte und linke Seitenfläche 24 des Hohlkörpers 10 sind jeweils als Formschlußfläche ausgebildet; die Seitenflächen 24 sind zueinander parallel. In der Mittellinie der rechten Seitenfläche 24 verläuft in Längsrichtung eine Formschlußrippe 26, während in der Mittellinie der linken Seitenfläche 24 eine in Längsrichtung verlaufende Formschlußnut 28 vorgesehen ist. Die Formschlußrippe 26 weist ein Steg 30 und einen in Bezug auf diesen in Querrichtung breiter werdenden Kopf 32 auf, während an der Formschlußnut 28 ein Halsteil 34 und ein bezogen auf diesen in Querrichtung breiter werdender Bodenhohlraum 36 vorgesehen sind.The right and left side surfaces 24 of the hollow body 10 according to FIG. 1 are each designed as a positive locking surface; the side surfaces 24 are parallel to one another. A positive locking rib 26 runs in the longitudinal direction in the center line of the right side surface 24, while a positive locking groove 28 extending in the longitudinal direction is provided in the center line of the left side surface 24. The form-fitting rib 26 has a web 30 and a head 32 which widens in relation to the latter in the transverse direction, while a neck part 34 and a base cavity 36 which widens in relation to this in the transverse direction are provided on the form-fitting groove 28.

Aus der rechten Seitenfläche 24 steht unter und über der Formschlußrippe 26 je eine Längsrippe 38 halbkreisförmigem Querschnittes hervor, während die linke Seitenläche 24 oberhalb und unterhalb der Formschlußnut 28 mit je einer zur Aufnahme der Längsrippen 38 geeigneten Rundnut 40 versehen ist.From the right side surface 24 a longitudinal rib 38 of semicircular cross-section projects under and above the form-fitting rib 26, while the left side surface 24 above and below the form-fitting groove 28 is provided with a round groove 40 suitable for receiving the longitudinal ribs 38.

Die Bauelemente gemäß Fig. 1 können ohne Verbindungselemente zusammengebaut werden, indem die Formschlußrippe 26 des einen Bauelementes durch Verschieben in Längsrichtung in die Formschlußnut 28 des benachbarten Bauelementes eingeführt wird. Die Rippen 38 beziehungsweise Rundnuten 40 verstärken einesteils die mechanische Verbindung, zum anderen verbessern sie den Wärmeübergang zwischen den benachbarten Bauelementen.1 can be assembled without connecting elements by inserting the form-locking rib 26 of the one component into the form-fitting groove 28 of the adjacent component by displacement in the longitudinal direction. The ribs 38 or circular grooves 40 reinforce the mechanical connection on the one hand, and on the other hand improve the heat transfer between the adjacent components.

Das in Fig. 2 dargestellte Bauelement unterscheidet sich von dem gemäß Fig. 1 darin, daß das Strahlungselement 18, die reflektierende Fläche 16 und der Kanal 22 fehlen. Dieses Element kann als Mittelstück zwischen zwei Elementen gemäß Fig. 1 verwendet werden (s. Fig. 4b). Der Hohlraum 12 kann mittels einer Öffnung 42 mit dem Innenraum der Wärmebehandlungsvorrichtung verbunden werden. Auf diese Weise kann durch das Anschlußelement 14 und den Hohlraum 12 zum Beispiel Schutzgas in den Innenraum geleitet werden, beziehungsweise besteht die Möglichkeit, unerwünschte Gase und Dämpfe aus dem Innenraum abzusaugen.The component shown in FIG. 2 differs from that according to FIG. 1 in that the radiation element 18, the reflecting surface 16 and the channel 22 are missing. This element can be used as a middle piece between two elements according to FIG. 1 (see FIG. 4b). The cavity 12 can be connected to the interior of the heat treatment device by means of an opening 42. In this way, shielding gas, for example, can be passed into the interior through the connecting element 14 and the cavity 12, or there is the possibility of extracting undesired gases and vapors from the interior.

Das in Fig. 3 gezeigte Bauelement unterscheidet sich von den schon beschriebenen dadurch, daß seine Seitenflächen 24 nicht parallel verlaufen, sondern miteinander einen Winkel von 45° einschließen und sich an der dem Anschlußelement 14 abgewandten Seite in einer Kante treffen. Mit diesen Elementeri können zwischen den Elementen gemäß den Fig. 1 und 2 Eckteile in einem Winkel von 45°, 90° oder 135° ausgebildet werden (s. Fig. 4a-4d).The component shown in FIG. 3 differs from those already described in that its side surfaces 24 do not run parallel, but rather form an angle of 45 ° with one another and meet at an edge on the side facing away from the connecting element 14. With these elements, corner parts can be formed at an angle of 45 °, 90 ° or 135 ° between the elements according to FIGS. 1 and 2 (see FIGS. 4a-4d).

In Fig. 4a ist ein Teil einer Wärmebehandlungsvorrichtung dargestellt, bei der jedes Bauelement mit einem Strahlungselement 18 ausgerüstet ist (s. Fig. 1), ausgenommen die die Ecken bildenden Elemente (Fig. 3).FIG. 4a shows a part of a heat treatment device in which each component is equipped with a radiation element 18 (see FIG. 1), with the exception of the elements forming the corners (FIG. 3).

Im Falle der Vorrichtung gemäß Fig. 4b weist an dem langen geraden Wandabschnitt nur jedes zweite Bauelement ein Strahlungselement 18 auf. Als Zwischenstück finden Elemente gemäß Fig. 2 Verwendung.In the case of the device according to FIG. 4b, only every second component has a radiation element 18 on the long straight wall section. Elements according to FIG. 2 are used as an intermediate piece.

Fig. 4c zeigt eine an einer Seite offene Wärmebehandlungsvorrichtung, die den Grundriß eines langgezogenen 0 aufweist, während Fig. 4d eine völlig geschlossene Wärmebehandlungsvorrichtung darstellt, die achteckig ist, d.h. annähernd einen kreisförmigen Grundriß hat.Fig. 4c shows a heat treatment device open on one side, which has the outline of an elongated 0, while Fig. 4d shows a completely closed heat treatment device which is octagonal, i. has approximately a circular floor plan.

Wie gezeigt wurde, können aus den erfindungsgemäßen Bauelementen Wärmebehandlungsvorrichtungen mit beliebigem Grundriß erstellt werden. Die Vorrichtung kann der Form des zu behandelnden Werkstückes angepaßt werden, wodurch eine gleichmäßige Erwärmung erzielt wird. Die Elemente sind leicht auseinandermontierbar und ebenso leicht in einer anderen Anordnung wieder zusammenfügbar.As has been shown, heat treatment devices with any layout can be created from the components according to the invention. The device can be adapted to the shape of the workpiece to be treated, whereby a uniform heating is achieved. The elements can be easily disassembled and just as easily reassembled in a different arrangement.
