KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der vorliegenden Erfindung bildet eine elektrische Heizvorrichtung für Heizkanäle bezw. Heizmufreln usw., wie.solche zum Trocknen, Kalzinieren oder langsamen Abkühlen und dergl. verwendet werden. Als Heizwiderstand dient das hierzu bereits bekannte kleinstückige kohlenhaltige Widerstandsmaterial. Der zu erhitzende Gegenstand, beispielsweise eine Heizmuffel, ist ganz oderThe subject of the present invention forms an electrical heating device for Heating channels respectively. Heating mantles, etc., such as those for drying, calcining or slowing down Cooling and the like can be used. The one already known for this purpose serves as the heating resistor small pieces of carbonaceous resistance material. The object to be heated, for example a heating muffle, is whole or

ίο teilweise eingebettet in kleinstückige kohlehaltige Widerstandsmasse, die zwischen der Muffel und einem die letztere umgebenden Mantel aus nicht leitendem Material angeordnet ist. Zu den beiden Enden der Wider-Standsmasse führen entsprechend gestaltete Stromzuleitungen. Der Querschnitt der Widerstandsmasse ist nicht in ihrer ganzen Länge gleichmäßig groß gehalten, sondern nimmt von dem einen Ende nach dem anderen allmählich zu. Dies hat zur Folge, daß bei Stromschluß die Muffel nicht in allen Teilen gleich starke Erhitzung-erfährt, vielmehr ein allmähliches Anwachsen der Hitze von dem einen Ende der Muffel nach dem anderen zu statt hat.ίο partially embedded in small pieces of carbonaceous Resistance mass, which is arranged between the muffle and a jacket made of non-conductive material surrounding the latter is. Correspondingly designed power lines lead to the two ends of the resistance mass. The cross section of the resistance mass is not kept evenly large along its entire length, but gradually decreases from one end to the other to. The consequence of this is that when there is a current connection, the muffle does not experience the same degree of heating in all parts, but rather a gradual increase in heat from one end of the muffle to the other took place.

Der Erfindungsgegenstand ist in Fig. 1 und 2 zur Anschauung gebracht, und zwar zeigtThe subject of the invention is shown in FIGS. 1 and 2, namely shows

Fig. ι denselben im senkrechten Querschnitt undFig. Ι the same in vertical cross section and

Fig. 2 im wagerechten Längsschnitt.Fig. 2 in a horizontal longitudinal section.

Die Muffel α wird von einem Mantel d umgeben. Zwischen Muffel und Mantel ist ein Zwischenraum gelassen, der durch die kleinstückige kohlehaltige Widerstandsmasse n> ausgefüllt wird. Wie ersichtlich, vergrößert sich der Querschnitt des Zwischenraumes in der Längsrichtung der Muffel α allmählich, so daß dementsprechend auch der Querschnitt der Widerstandsmasse w zunimmt. An jedem Ende führen von beiden Seiten zu der letzteren Zuleitungen b, b und c, c für den elektrischen Strom.The muffle α is surrounded by a jacket d . A gap is left between the muffle and the jacket, which is filled by the small, carbonaceous resistance mass n>. As can be seen, the cross section of the space increases gradually in the longitudinal direction of the muffle α , so that the cross section of the resistance mass w increases accordingly. At each end, leads b, b and c, c for the electric current lead to the latter from both sides.
