Description

Zweiteilige Stahlflasche und Verfahren zum Einfüllen von Schutzmasse Flaschen für Gase werden meistens durch Ziehen aus einem Stück hergestellt; sie haben einen verhältnismäßig engen Hals, durch den, falls es sich um Gase handelt, die leicht zerfallen und daher hiergegen durch Schutzmasse geschützt werden müssen, auch die Schutzmasse einzubringen ist, was Schwierigkeiten bereitet.Two-part steel bottle and method for filling in protective mass Bottles for gases are mostly made from one piece by drawing; she have a relatively narrow neck through which, in the case of gases, which easily disintegrate and therefore have to be protected against this by protective material, the protective compound must also be introduced, which causes difficulties.

Erfindungsgemäß wird diesem Mangel dadurch abgeholfen, daß der Flaschenmantel einer aus Mantel und Boden bestehenden Flasche am Bodenende mit Gewinde versehen ist, in das der Boden eingeschraubt und dichtgeschweißt wird.According to the invention, this deficiency is remedied in that the bottle jacket a bottle consisting of a jacket and a base with a thread at the base end into which the base is screwed and welded tight.

Das Einfüllen der Schutzmasse und ihre Verdichtung erfolgen vom Bodenende aus, indem der Boden entfernt und in das Gewinde ein zylindrisches Füllrohr eingeschraubt wird, welches mit Schutzmasse gefüllt wird, auf welche ein Sperrblech oben aufgebracht und durch einen Kolben hydraulisch oder mechanisch in die Flasche gedrückt und verdichtet weird. Hietauf wird das Füllrohr entfernt und der Boden eingeschraubt.The filling of the protective mass and its compaction take place from the bottom end by removing the bottom and screwing a cylindrical filling tube into the thread is, which is filled with protective mass, on which a barrier plate is applied on top and pressed into the bottle hydraulically or mechanically by a piston and compressed weird. The filling pipe is then removed and the base screwed in.

In den Abb. i und 2 ist die Erfindung an zwei Beispielen dargestellt.In Figs. I and 2 the invention is shown in two examples.

Abb. i stellt einen Schnitt durch die gefüllte Flasche mit eingesetztem Boden und Abb. 2 einen Schnitt durch die gefüllte Flasche mit eingesetzter Sperrplatte und aufgeschraubtem Füllrohr dar, wobei der wieder zurückgefahrene Teil des Preßkolbens die Funktion der Sperrplatte zeigt, welche die Masse festhält.Fig. I shows a section through the filled bottle with inserted Bottom and Fig. 2 a section through the filled bottle with the locking plate inserted and screwed-on filling tube, with the retracted part of the plunger shows the function of the locking plate that holds the mass in place.

In diesen Abbildungen bezeichnet 6 den Mantel der Flasche, 8 das Mantelgewinde, io den Boden, 1:2 eine '-Kut oberhalb des Gewindes, 14 eine Sperrplatte, 16 Sieblöcher, 18 Schlitze, :2o ein Füllrohr. :22, einen Preßkolben, :24 eine Schweißdichtung. 26 b einen Schutzring und 28 ein Sieb. Die Flasche besteht aus dem mit Hals versehenen Mantel 6 und dem Boden io. Der Mantel hat an seinem unteren Ende ein Innengewinde 8; oberhalb des Gewindes befindet sich eine Nut 12, in die eine Sperrplatte, die der Bodenform angepaßt ist, einrastet, indem der durch die Schlitze 18 unterteilte Rand elastisch nachgibt. Der Boden io, der mit passendem Außengewinde versehen ist, wird eingeschraubt und durch eine Schweißhaht:24 abgedichtet. Diese Schweißnaht wird durch einen auf das Mantelende aufgeschrumpften Ring :26, der als Winkelring ausgebildet ist, gegen Beschädigungen geschützt. Am Flaschenhals ist ein Siebrohr 28 angebra,cht. Um den Zerfall des Gases, mit welchem die Flasche gefüllt werden soll, zu verhüten, werden Schutzmassen in die Flaschen eingefüllt und verdichtet. Zu diesem Zweck wird der Boden io entfernt und an seiner Stelle ein Füllrohr 2o, das mit einem dem Gewinde 8 entsprechenden Gewinde versehen ist, eingeschraubt. Das Siebrohr 28 verhindert hierbei den Austritt der Masse durch den Flaschenhals. Die Flasche wird mit der genau dosierten Menge Schutzmasse gefüllt, welche zunächst einen größeren Raum als den Flascheninhalt einnimmt, während der Überschuß im Füllrohr :2o Platz findet. Oben in die Schutzmasse wird das Sperrblech 14 durch den Preßkolben eingeführt und erfährt im Füllrohr durch die Funktion der Radialschlitze eine Verringerung des Außendurchmessers unter Aufnahme einer federnden Spannung. Mit zunehmender Verdichtung der Schutzmasse wird das Sperrblech durch den Preßkolben 2,2 mit nach unten genommen, und es rastet das Sperrblech 14 in der Endstellung in die Nut 12 ein, indem sich das Sperrblech 14 wieder ausdehnen kann. Nunmehr kann der Preßkolben 22 wieder zurückgefahren werden, ohne daß sich die verdichtete Schutzmasse lockern oder ihr Volumen wieder vergrößern kann. Nach der Entfernung des Füllrohres:2o wird der Boden io eingeschraubt. Die Löcher 16 im Sperrblech 14 dienen dem Durchtritt von pulverförmiger Masse zur Vermeidung von schädlichen Hohlräumen zwischen dem Sperrblech 14 und dem Boden io; die pulverförmige. Masse geht, soweit sie zum Ausgleich benötigt wird, in beiden Richtungen durch. Nach der Einbringung des Bodens wird die Flasche an der Stelle :24 dichtgeschweißt und nach erfolgter Prüfung der winkelförmige Schutzring 26 aufgeschrumpft.In these figures, 6 denotes the jacket of the bottle, 8 the jacket thread, io the bottom, 1: 2 a groove above the thread, 14 a locking plate, 16 sieve holes, 18 slots,: 2o a filling tube. : 22, a plunger,: 24 a welding seal. 26 b a protective ring and 28 a sieve. The bottle consists of the necked jacket 6 and the bottom io. The jacket has an internal thread 8 at its lower end; Above the thread there is a groove 12 into which a locking plate, which is adapted to the shape of the bottom, engages in that the edge divided by the slots 18 yields elastically. The bottom io, which has a matching external thread, is screwed in and sealed with a welded seam: 24. This weld seam is protected from damage by a ring: 26 which is shrunk onto the jacket end and is designed as an angle ring. A sieve tube 28 is attached to the bottle neck. In order to prevent the decomposition of the gas with which the bottle is to be filled, protective compounds are poured into the bottles and compressed. For this purpose, the bottom io is removed and a filling pipe 2o, which is provided with a thread corresponding to the thread 8 , is screwed in in its place. The sieve tube 28 prevents the mass from escaping through the bottle neck. The bottle is filled with the precisely dosed amount of protective compound, which initially takes up a larger space than the contents of the bottle, while the excess finds space in the filling tube: 2o. At the top of the protective compound, the blocking plate 14 is inserted through the plunger and, as a result of the function of the radial slots, experiences a reduction in the outer diameter in the filling tube while absorbing a resilient tension. With increasing compression of the protective mass, the locking plate is taken down by the plunger 2, 2, and the locking plate 14 engages in the end position in the groove 12, in that the locking plate 14 can expand again. Now the plunger 22 can be moved back again without the compressed protective mass loosening or being able to increase its volume again. After removing the filling pipe: 2o the bottom is screwed in. The holes 16 in the blocking plate 14 are used for the passage of powdery mass to avoid damaging cavities between the blocking plate 14 and the floor io; the powdery. As far as it is needed for compensation, the mass goes through in both directions. After the bottom has been introduced, the bottle is welded tightly at position: 24 and, after the test has been carried out, the angular protective ring 26 is shrunk on.
