Description
Elektrischer Heizmantel in Verbindung mit Widerstandselementen zum Beheizen des vom Mantel eingeschlossenen Gegenstandes Die Erfindung bezieht sich auf einen elektrischen Heizmantel, dessen Querschnitt U-förmig ist und der Widerstandselemente zum Beheizen des vom Mantel eingeschlossenen Gegenstandes enthält, der ferner als Spannband für den zu beheizenden Gegenstand ausgebildet ist und mittels Spannlaschen zu einem Ring verbunden werden kann.Electrical heating jacket in connection with resistance elements for Heating the Item Enclosed by the Mantle The invention relates on an electrical heating jacket, the cross-section of which is U-shaped, and the resistance elements for heating the object enclosed by the jacket, which also serves as Tensioning band is designed for the object to be heated and by means of tensioning straps can be connected to a ring.
Bei diesen Mänteln sind die Schenkel des U-förmigen Querschnittes bisher im Preßvorgang voll aus dem flachen Material hergestellt, so daß diese Art von Mänteln auf vorher bestimmte Abmessungen des zu beheizenden Gegenstandes angewiesen ist. Man muß daher ein großes Lager solcher Mäntel verschiedener Krümmung halten, was ebenfalls nachteilig ist.In these jackets, the legs are of the U-shaped cross-section so far made entirely of the flat material in the pressing process, so that this type of coats dependent on previously determined dimensions of the object to be heated is. One must therefore keep a large stock of such coats of various curvatures, which is also disadvantageous.
Außerdem hat man zum Anbringen von Strahlringen an glatte, z. B. für Heizung bestimmte Strahlrohre vorgeschlagen, den für den Strahlring bestimmten Blechstreifen, welcher die Form einer Spirale hat, mit weiten und tiefen Ausschnitten an der an das Strahlrohr sich auflegenden Innenkante zu versehen. Bei dem durch Stauchdruck herbeigeführten Anschmiegen des in der Form vorbereiteten Blechstreifens an das Rohr legen sich jedoch bereits die Kanten eines Ausschnittes des spiralförmigen Blechstreifens nicht übereinander, sondern nebeneinander. Man ist hier an die Spiralform des anzubringenden Werkstückes angewiesen.In addition, you have to attach radiation rings to smooth, z. B. for Heating proposed certain radiant tubes, the sheet metal strip intended for the radiant ring, which has the shape of a spiral, with wide and deep cutouts at the to provide the nozzle with the inner edge resting on it. With that by upsetting pressure brought about nestling of the sheet metal strip prepared in the mold to the However, the edges of a section of the spiral-shaped pipe are already laid down Sheet metal strips not on top of each other, but next to each other. One is here at the spiral shape of the workpiece to be attached.
Außerdem ist ein aus auswechselbaren Heizkörpern bestehendes Heizband mit einem außenliegenden Zugband bekanntgeworden, bei welchem die einzelnen Heizkörper an ihren zusammenstoßenden Seiten Faltungen besitzen, wodurch beim Anspannen des Zugbandes zuverlässige Kontakte und gegenseitige Halterung in den Faltungen gewährleistet werden.In addition, there is a heating tape consisting of replaceable radiators became known with an external drawstring, in which the individual radiators have folds on their abutting sides, whereby when tightening the The drawstring ensures reliable contacts and mutual retention in the folds will.
Die Erfindung löst im Unterschied zu den bisherigen Vorschlägen die Aufgabe, daß beim Biegen des U-förmig im Querschnitt ausgebildeten und so auf Lager gehaltenen noch gestreckten Mantelstreifens Heizmäntel für verschiedene Krümmungen ermöglicht werden, wobei beim Biegen des Mantelstreifens Sicherungen gegen Verschiebungen der innenliegenden Widerstandsheizelemente gegeneinander gegeben sind.In contrast to the previous proposals, the invention solves the Task that formed when bending the U-shaped in cross section and so in stock held still stretched coat strips heating coats for different curvatures be made possible, with safeguards against displacement when the jacket strip is bent of the internal resistance heating elements are given against each other.
Zu diesem Zweck ist der Heizmantel beschriebener Gattung erfindungsgemäß derart ausgebildet, daß die Schenkel des U-förmigen Querschnittes mittels Einschnitten, beginnend an der Außenkante, zu Lappen geformt und an den Schnittkanten mit Wellungen oder Prägungen versehen sind, welche beim Biegen des Mantels sich unter die Lappen einschieben. Außerdem ist in weiterer Ausführung der Erfindung bei dem Heizmantel, in dessen Innenraum die Heizelemente in keramischen Formsteinen eingebettet sind, vorgesehen, daß die Formsteine an ihren Berührungsflächen mit Falzungen in an sich bekannter Weise zum Verhindern ihres gegenseitigen Verschiebens versehen sind.For this purpose, the heating jacket of the type described is according to the invention designed such that the legs of the U-shaped cross-section by means of incisions, starting at the outer edge, shaped into lobes and with corrugations on the cut edges or embossments are provided, which when the jacket is bent under the tabs slide in. In addition, in a further embodiment of the invention in the heating jacket, in the interior of which the heating elements are embedded in ceramic shaped stones, provided that the shaped stones on their contact surfaces with folds in itself are provided in a known manner to prevent their mutual displacement.
Die Erfindung ist in der Beschreibung unter Hinweis auf die Zeichnung an Hand von Ausführungsbeispielen erläutert.The invention is in the description with reference to the drawing explained on the basis of exemplary embodiments.
F i g. 1 stellt den Mantel in Ansicht und F i g. 2 denselben im Grundriß dar; F i g. 3 zeigt im Querschnitt nach a-a der F i g. 2 eine Ausführungsform des Mantels; in F i g. 4 ist ein Teil des Schenkels des U-Profils in Draufsicht und in F i g. 5 derselbe im Schnitt nach b-b der F i g. 4 dargestellt, während F i g. 6 das Werkstück als Zwischenerzeugnis darstellt, das den Mantel noch im gestreckten Zustand vorführt; F i g. 7 bedeutet den Mantel in einer anderen Anwendungsform, während die F i g. ß denselben im Schnitt nach c-c der F i g. 7 veranschaulicht.F i g. 1 shows the jacket in view and FIG. 2 the same in plan dar; F i g. 3 shows in cross section according to a-a of FIG. 2 an embodiment of the Coat; in Fig. 4 is part of the leg of the U-profile in plan view and in Fig. 5 the same in section according to b-b of FIG. 4, while FIG. 6 shows the workpiece as an intermediate product that still has the jacket in the stretched position State demonstrates; F i g. 7 means the coat in another application form, while the F i g. ß the same in section according to c-c of FIG. 7 illustrates.
Gemäß der Zeichnung umschließt der Mantel l den zu beheizenden Gegenstand 2. Er ist im Querschnitt U-förmig und nimmt gemäß F i g. 3 die Heizelemente 3, z. B. Heizspiralen, auf, die in Formsteinen 4 aus einer keramischen Masse eingebettet sind. Die Formsteine sind an der Innenwand des Mantels über den Umfang aneinandergereiht. Sie besitzen an ihren Berührungsflächen Falze oder ähnlich beschaffene Einkerbungen und Erhebungen, mittels welcher sie gegen Verschiebungen gesichert sind.According to the drawing, the jacket l encloses the object to be heated 2. It is U-shaped in cross section and takes up according to FIG. 3 the heating elements 3, e.g. B. heating coils, which are embedded in shaped blocks 4 made of a ceramic mass are. The shaped stones are lined up on the inner wall of the jacket over the circumference. They have folds or similar notches on their contact surfaces and elevations by means of which they are secured against displacement.
Wie die F i g. 2 und 6 sowie F i g. 4 und 5 zeigen, sind die Schenkel l a, beginnend an der Außenkante, gegen die Biegekante des Mantels 1 eingeschnitten, so daß Lappen 5 entstehen, an deren einer Schnittkante Prägungen oder Wellungen 6 ausgebildet sind, wie die F i g. 5 zeigt. Aus diesem noch geradegestreckten U-förmig im Querschnitt geformten Mantel 1 - ein Zwischenerzeugnis nach F i g. 6 - kann ein Mantel in Verbindung mit Elementen zum Beheizen von Gegenständen 2 derart aus einem Teil am Ort der Montage gebogen werden, daß der fertige Mantel jeder Krümmung der Oberfläche des Gegenstandes 2 sofort angepaßt ist.As the F i g. 2 and 6 as well as FIG. Figures 4 and 5 show the legs l a, starting at the outer edge, against the bending edge of the jacket 1 incised, so that flaps 5 arise, on one cut edge of which is embossed or corrugations 6 are formed, as in FIG. 5 shows. From this still straightened U-shaped in cross-section shaped jacket 1 - an intermediate product according to FIG. 6th - Can a jacket in connection with elements for heating objects 2 in this way be bent from one part at the place of assembly, so that the finished jacket of any curvature the surface of the object 2 is immediately adapted.
Beim Biegen eines solchen noch gestreckten Mantels schieben sich die Prägungen 6 unter die Lappen 5 derart, daß im fertigen Zustand der Mantel an beiden Schenkeln 1a eine kontinuierliche Fläche aufweist.When such a stretched jacket is bent, the Embossings 6 under the tabs 5 in such a way that in the finished state the jacket on both Legs 1a has a continuous surface.
Ein in solcher Weise gestalteter Mantel kann im Rahmen der Erfindung noch weitere Anwendungsformen haben, wie die F i g. 7 und 8 zeigen. Hier wird der zu beheizende Gegenstand 2 an seiner Oberfläche mit einer Bandage 7, die im Glimmer gebettete Heizelemente besitzt, umschlossen, welche mittels eines Spannbandes 8 mit Hilfe von Spannlaschen schließbar ist und angepreßt wird. Der einteilige und mittels Spannlaschen schließbare Mantel 1 kann an seiner Innenfläche Isoliereinlagen oder reflektierende Schichten besitzen.A jacket designed in this way can be used within the scope of the invention still have other forms of application, such as FIG. 7 and 8 show. Here is the object to be heated 2 on its surface with a bandage 7, which is in the mica has embedded heating elements, enclosed, which by means of a tensioning strap 8 can be closed with the help of clamping straps and is pressed on.
