Description

Verfahren zum Zuschmelzen von Hohlgefäßen aus Glas u. dgl. Die Erfindung betrifft ein Verfahren und geeignete Vorrichtungen zum Zuschmelzen von Hohlgefäßen aus Glas und ähnlichen Stoffen, in denen sich ein Überdruck befindet.Method for melting hollow vessels made of glass and the like relates to a method and suitable devices for melting hollow vessels made of glass and similar materials in which there is an overpressure.

Bisher war ein Zuschmelzen solcher Gefäße deshalb nicht möglich, weil der überdruck das im Schmelzprozeß befindliche Glas aufblies und ein Zuschmelzen zum mindesten so lange verhinderte, bis Innen- und Außendruck sich ausgeglichen hatten. So war es weder möglich, Glasgefäße, in denen sich komprimierte Gase befanden, noch solche, in denen sich verflüssigte Gase oder bei sehr niedriger Temperatur siedende Flüssigkeiten befanden, durch Zuschmelzen zu verschließen. Dies wird nach dem Verfahren der vorliegenden Erfindung ermöglicht.Until now, such vessels could not be melted shut because the overpressure inflated the glass in the melting process and melted it prevented at least until the internal and external pressure equalized had. So it was not possible to use glass vessels containing compressed gases, nor those in which there are liquefied gases or at very low temperatures boiling liquids were found to be sealed by melting. This will be after the method of the present invention enables.

Das Verfahren besteht darin, daß die Gefäße ganz oder nur mit dem zuzuschmelzenden Ende, das zweckmäßig schon vor dem Einfüllen des Inhaltes oder vor dem Hineinbringen des Überdruckes als verengter Rohransatz ausgebildet ist, in einen Raum gebracht werden, in dem mindestens der gleiche Druck wie in dem zu verschließenden Gefäß, herrscht. In diesem Raum wird dann der Prozeß des Zuschmelzens vorgenommen. Befinden sich in den Gefäßen verflüssigte Gase, zu deren Verflüssigung nicht nur starker Druck, sondern auch Kälte erforderlich ist, so geschieht das Zuschmelzen in einem Raume, in dem nicht nur der betreffende Druck, sondern auch mindestens die gleiche Kälte herrscht wie in dem zuzuschmelzenden Gefäß. Für das Zuschmelzen verwendet man am besten die Wärme des elektrischen Lichtbogens oder Widerstandes.The method consists in that the vessels wholly or only with the End to be melted, which is expedient before filling in the contents or is designed as a constricted pipe socket before the overpressure is brought in, be brought into a room in which at least the same pressure as in the one occluding vessel, prevails. The process of melting down then takes place in this space performed. If there are liquefied gases in the vessels, they should be liquefied Not only strong pressure but also cold is required, so the melting occurs in a room in which not only the relevant pressure, but also at least the same cold prevails as in the vessel to be melted shut. For melting it is best to use the heat of the electric arc or resistor.

Vorteilhaft ist es, das Druckgefäß bzw. den Druckraum, in dem der Prozeß des Zuschmelzens vor sich geht, mit _ einer oder mehreren Stellen zu versehen, an denen geschmolzen werden kann, und vorteilhaft geschieht das Einführen und Wiederherausnehmen des zuzuschmelzenden Glasrohrendes in einer Weise, daß dadurch aus dem Druckraum kein Druck verlorengeht. Zu diesem Zweck befinden sich an geeigneten Stellen des Druckraumes Ventile, die zwar das Einführen eines Rohrendes in den Druckraum gestatten, sich jedoch beim Wiederherausziehen dieses Rohrendes aus dem Druckraum selbsttätig verschließen und keinen Druck herauslassen. Diese Rückschlagventile können z. B. so konstruiert sein, daß sie aus einer in der Mitte durchstochenen, nach dem Druckraum zu ein wenig gewölbten, in der Mitte freiliegenden, im übrigen beiderseits von je einem flachen Metallring gehaltenen Gununiplatte bestehen, deren durchstochener Teil sich durch den vom Druckraum kommenden Druck verschließt. beim Einführen des Glasrohrendes jedoch sich so weit öffnet, daß er das Einführen des zuzuschmelzenden Gefäßendes zuläßt und sogar ein Hin- und Herbewegen und Drehen gestattet. Wird das vorteilhaft möglichst enge Ende des zuzuschmelzenden Gefäßes durch das Rückschlagventil in den Druckraum eingeführt, so kann es bei diesem Einführen einen elektrischen Stromkreis schließen und beim Herausnehmen wieder unterbrechen. Im Innern des Druckraumes befindet sich über der Einführungsstelle die Wärmequelle (Lichtbogen oder Widerstand), in deren Nähe das Glas zugeschmolzen wird, nachdem durch das Eindringen. des offenen Endes in den Druckraum der Gefäßinhalt unter den gleichen Druck gesetzt ist, der im Druckraum herrscht. Alsdann bietet das Zuschmelzen keine weitere Schwierigkeit, da im Moment des Schmelzprozesses in dem Gefäß kein höherer Druck herrscht als in dem Raume, in dem sich das Endstück des Gefäßes befindet. Befinden sich in dem Gefäß Stoffe, die leicht entzündbar sind, so kann der Druckraum mit einem Gase gefüllt sein, das die Entzündung verhindert.It is advantageous to use the pressure vessel or the pressure space in which the The process of melting is going on, with one or more places, which can be melted, and advantageously the insertion and removal takes place the end of the glass tube to be fused in such a way that it is removed from the pressure chamber no pressure is lost. For this purpose, the Pressure chamber valves that allow the insertion of a pipe end into the pressure chamber, however, automatically when this pipe end is pulled out of the pressure chamber close and do not let out any pressure. These check valves can, for. B. be constructed in such a way that it is pierced in the middle, following the pressure chamber to slightly arched, exposed in the middle, otherwise on both sides of each a flat metal ring held gununi plate, whose pierced Part is closed by the pressure coming from the pressure chamber. when inserting the However, the end of the glass tube opens so far that it allows the insertion of the material to be fused Permits the vessel and even allows it to move back and forth and rotate. It will advantageously the narrowest possible end of the vessel to be melted through the check valve Introduced into the pressure chamber, it can be an electrical one during this introduction Close circuit and when removing interrupt again. The heat source is located in the interior of the pressure chamber above the introduction point (Arc or resistance) near which the glass is melted shut after by penetrating. of the open end into the pressure chamber of the vessel contents under the the same pressure is set that prevails in the pressure chamber. Then the melting offers no further difficulty, since at the moment of the melting process in the vessel there is no The pressure is higher than in the room in which the end piece of the vessel is located. If there are substances in the vessel that are easily flammable, the pressure chamber can be filled with a gas that prevents inflammation.
