Enough radiators to attain the desired heating effect are accommodated next to each other in a common reflector. The radiators are preferably rod-shaped or rectangular.

Description

Die Erfindung betrifft eine Infrarot-Strahlungsanlage mit keramischen Heizkörpern, die von Reflektoren umschlossen sind. Solche Anlagen, wie sie beispielsweise den Gegenstand des auf den Anmelder zurückgehenden deutschen Patentes 20 52 304 bilden, haben für jeden keramischen Heizkörper einen, dessen Abmessungen angepaßten Reflektor, der den Heizkörper einseitig umschließt. Je nach der erforderlichen Heizleistung sind die elektrischen Heizkörper und die dazugehörigen Reflektoren verschieden groB, was eine verhältnismäßig große Lagerhaltung für die verschiedenen Typen von Infrarot-Strahlungsanlagen erforderlich macht. Außerdem ergeben sich mit den bekannten Heizkörpern und Reflektoren Schwierigkeiten bei großflächigen Anlagen, insbesondere bei von einer ebenen Fläche abweichenden Werkstückoberflächen.The invention relates to an infrared radiation system with ceramic radiators, which are surrounded by reflectors. Such systems, as they form the subject of the applicant's German patent 20 52 304, have for each ceramic radiator one whose dimensions are adapted reflector that surrounds the radiator on one side. Depending on the heating power required, the electric radiators and the associated reflectors are of different sizes, which necessitates a relatively large inventory for the various types of infrared radiation systems. In addition, with the known radiators and reflectors, difficulties arise in large-area systems, in particular in the case of workpiece surfaces deviating from a flat surface.

Aufgabe der Erfindung ist es, diese Mängel zu beheben und eine Infrarot-Strahlungsanlage zu schaffen, die sich an die jeweils erforderlichen Heizleistungen und an die verschiedensten Geometrien der Bestrahluhgsgüter in einfachster Weise anpassen läßt, ohne daß eine umfangreiche Lagerhaltung erforderlich wird.The object of the invention is to remedy these shortcomings and to provide an infrared radiation system which can be adapted in the simplest manner to the heating outputs required and to the most varied geometries of the irradiation goods, without extensive storage being necessary.

Dies wird erfindungsgemäß dadurch erreicht, daß Reflektoren verwendet werden, die an ihren Rändern mit Scharniergliedern, Gelenken o. dgl.versehen und miteinander durch Trag- oder Verbindungsbolzen verbindbar sind. Die Scharnierteile oder Gelenke o. dgl. ermöglichen eine Verbindung mehrerer Reflektoren. Andererseits sind die Scharnierteile zur Aufnahme von sich über mehrere Reflektoren erstreckende Tragelemente wie Stäbe, Rohre o. dgl. eingerichtet, so daß bei der Montage größerer Anlagen besondere Tragkonstruktionen eingespart werden können. Aus Gründen einer erleichterten Lagerhaltung werden vorzugsweise einheitliche oder gleichartige Strahler und Reflektoren verwendet.This is achieved according to the invention in that reflectors are used which are provided at their edges with hinge members, joints or the like and which can be connected to one another by means of supporting or connecting bolts. The hinge parts or joints or the like enable a connection of several reflectors. On the other hand, the hinge parts for receiving support elements which extend over a plurality of reflectors such as rods, pipes or the like. Set up, so that special supporting structures can be saved when assembling larger systems. For reasons of easier storage, uniform or similar emitters and reflectors are preferably used.

Erfindungsgemäß erstreckt sich der zur Anwendung gelangende Reflektor über mehrere Heizkörper und hat dabei nebeneinanderliegende Anschlüsse für die wahlweise Anbringung einer dem zu erzielenden Heizeffekt entsprechenden Anzahl von Heizkörpern.According to the invention, the reflector used extends over several radiators and has adjacent connections for the optional attachment of a number of radiators corresponding to the heating effect to be achieved.

Mit besonderem Vorteil sind die Heizkörper stab- oder rechteckförmig geformt, wobei die Heizkörper parallel zur Reflektorlängsachse verlaufend oder auch quer dazu im Reflektor untergebracht sind.The radiators are particularly advantageously rod-shaped or rectangular in shape, the radiators being arranged parallel to the longitudinal axis of the reflector or also transversely thereto in the reflector.

Zweckmäßig sind die Heizkörper mit im Endbereich liegenden Auflagern zur Befestigung im Reflektor versehen und die Stromanschlüsse an die Enden der Heizkörper verlegt.The radiators are expediently provided with supports in the end area for fastening in the reflector and the power connections are laid at the ends of the radiators.

Der Erfindungsgedanke ist in den Zeichnungen wie folgt dargestellt und zwar zeigen:

  • Fig. 1 eine Draufsicht auf einen zur Aufnahme von beispielsweise drei Heizkörpern geeigneten Reflektor;
  • Fig. 2 einen Schnitt des Reflektors gemäß Fig. 1, bestückt mit zwei keramischen Heizkörpern;
  • Fig. 3 die perspektivische Ansicht eines Reflektors mit drei darin untergebrachten keramischen Heizkörpern;
  • Fig. 4 eine schematische Darstellung der gelenkigen Verbindung mehrerer Reflektoren mit den Tragbolzen;
  • Fig. 5 bis 7 Draufsicht, Seitenansicht und Ansicht von unten eines keramischen Heizkörpers, wie er vorzugsweise.bei den erfindungsgemäßen Anlagen zur Verwendung gelangt;
  • Fig. 8 ein Bestückungsbeispiel einer aus zwölf Reflektoren bestehenden Strahlungsfläche;
  • Fig. 9 bis 16 schematische Darstellungen über Infrarot-Strahlungsanlagen aus erfindungsgemäßen Reflektoren und,Heizkörpern für verschiedene Anwendungszwecke.
The concept of the invention is shown in the drawings as follows, namely:
  • Figure 1 is a plan view of a reflector suitable for receiving, for example, three radiators.
  • FIG. 2 shows a section of the reflector according to FIG. 1, equipped with two ceramic radiators;
  • 3 shows the perspective view of a reflector with three ceramic radiators accommodated therein;
  • Figure 4 is a schematic representation of the articulated connection of several reflectors with the support bolts.
  • Fig. 5 to 7 top view, side view and bottom view of a ceramic radiator, as it is preferably used in the systems according to the invention;
  • F ig. 8 shows an example of equipment for a radiation surface consisting of twelve reflectors;
  • 9 to 16 are schematic representations of infrared radiation systems from reflectors according to the invention and radiators for various purposes.

In Fig. 1 und 2 ist ein Reflektor wiedergegeben, der vorteilhaft aus hochglänzendem Edelstahl besteht. Der Reflektor ist so geformt, daß sich zu beiden Seiten einem entsprechend breiten Rückenteil 1 schräggestellte Wände 2 anschließen, wobei im Rückenteil 1 Bohrungsgruppen 3a, 3b oder 3c vorgesehen sind für den wahlweisen Einbau von noch später zu beschreibenden elektrischen Heizkörpern 4. Außerdem sind am Rand Durchbohrungen 5 vorgesehen für das Hindurchführen von an den Heizkörpern 4 vorgesehenen Stromzuleitungen 6 (Fig. 1).1 and 2, a reflector is shown, which advantageously consists of high-gloss stainless steel. The reflector is shaped in such a way that a correspondingly wide back part 1 adjoins inclined walls 2 on both sides, 1 groups of holes 3a, 3b or 3c being provided in the back part for the optional installation of electric radiators to be described later Bores 5 provided for the passage of current leads 6 provided on the radiators 4 (FIG. 1).

Schließlich weist der Reflektor an den Längsrändern der Teile 2 Buchsen 7 auf, die zur Aufnahme von Gelenk- oder Tragbolzen 8 bestimmt sind. Die Buchsen 7 sind derart versetzt und in solchem Abstand zueinander angeordnet, daß zwischen sie ein weiterer Reflektor mit seinen Gelenkbuchsen eingesetzt werden kann und auf diese Weise eine scharnierartige Verbindung mehrerer Reflektoren miteinander entsteht.Finally, the reflector has 2 bushings 7 on the longitudinal edges of the parts, which are intended for receiving joint or support bolts 8. The sockets 7 are offset and arranged at such a distance from one another that a further reflector with its hinge bushes can be inserted between them and in this way a hinge-like connection of several reflectors is produced.

Selbstverständlich ist es auch möglich, in die Buchsen 7 Tragstäbe o. dgl. einzusetzen, die es gestatten, in einfachster Weise mehrere Reflektoren hintereinanderliegend zu einer Anlage aufzubauen.Of course, it is also possible to use support rods or the like in the bushings 7, which allow several reflectors to be constructed one behind the other in a simple manner to form a system.

Wie bereits gesagt, lassen sich in einem eben beschriebenen Reflektor mehrere keramische Heizkörper 4 nebeneinander unterbringen, je nachdem, wie groß die zu erzielende Heizleistung sein soll. Es werden dann beispielsweise ein, zwei oder drei Heizkörper 4 nebeneinander oder an einem der Anschlüsse 3.a, 3b oder 3c befestigt.As already mentioned, several ceramic radiators 4 can be accommodated next to one another in a reflector just described, depending on how large the heating output to be achieved should be. Then, for example, one, two or three radiators 4 are attached next to each other or on one of the connections 3.a, 3b or 3c.

Mit der gezeigten Reflektorausbildung ist es ohne Schwierigkeiten möglich, beliebig viele Reflektoren neben- und hintereinander vorzusehen, die dann untereinander durch die Scharnier verbunden sind und sich dem jeweiligen Bedarf entsprechend bzw. dem Verlauf der Oberfläche des zu beheizenden Werkstückes W anpassen können, wie es die Fig. 9 bis 16 schematisch wiedergeben.With the reflector design shown, it is possible without difficulty to provide any number of reflectors side by side and one behind the other, which are then connected to one another by the hinge and can adapt to the particular need or to the shape of the surface of the workpiece W to be heated, as is the case Fig. 9 to 16 show schematically.

Von besonderem Vorteil ist die Ausführung der zur Verwendung gelangenden keramischen Heizkörper. Diese besitzen, wie es besonders die Fig. 5 bis 7 erkennen lassen, eine schlanke, lärgliche, rechteckige Form, wobei die in den Keramikkörper eingebetteten Heizleiter 10 den in Fig. 7 gestrichelt eingezeichneten Verlauf haben und in die an den Enden der Keramikkörper 4 vorgesehenen Stromzuleitungen 6 übergehen.The design of the ceramic radiators used is of particular advantage. As can be seen particularly in FIGS. 5 to 7, these have a slender, noisy, rectangular shape, the heating conductors 10 embedded in the ceramic body having the course shown in dashed lines in FIG. 7 and into those provided at the ends of the ceramic body 4 Override power supply lines 6.

Andererseits sind die Heizkörper nicht, wie bisher üblich, in ihrer Mitte mit einem Befestigungsstutzen versehen, sondern sie besitzen im Endbereich aus Keramikmasse gebildete Auflager 9, durch die beispielsweise ein Befestigungsdraht 11 hindurchgeführt ist. Wegen der Länge der Keramikkörper sind auf ihrer Rückseite zwei solcher Auflager 9 vorgesehen. Bei der wahlweisen Montage der Heizkörper im Reflektor werden die Befestigungsdrähte 11 durch die Bohrungen 3a, 3b oder 3c hindurchgeführt und auf der Reflektorrückseite miteinander verdrillt. Die Stromzuleitungen 6 hingegen werden durch die Bohrungen 5 hindurchgeführt und auf der Reflektorrückseite mit Anschlußklemmen verbunden.On the other hand, the radiators are not provided with a fastening piece in the middle, as was customary hitherto, but instead they have supports 9 made of ceramic mass in the end region, through which a fastening wire 11 is passed, for example. Because of the length of the ceramic body two such supports 9 are provided on the back. When the radiators are optionally installed in the reflector, the fastening wires 11 are passed through the bores 3a, 3b or 3c and twisted together on the back of the reflector. The power supply lines 6, however, are passed through the bores 5 and connected to terminals on the rear of the reflector.
