Description

" Flammensperre für Schneidbrenner. " --------------------------------------- Vorliegende Erfindung bezieht sich auf die neuartige Anordnung einer Flammensperre für Schneidbrenner vorzugsweise aus einem porösen Sintermetall. Es ist bereits bekannt, ein Griffrohr, das zur Aufnahme eines Schweiss-, Schneid-oder Lötbrenners dient, mit einer eingebauten Flammensperre aus Sintermetall zu versehen. Dieser Vorschlag dürfte jedoch unzulänglich sein, da der Rückschlag immer noch in die mischkammer gelangen kann, in denen es auch schon zu Explosionen gekommen ist. Durch diese Anordnung wird höchstens eine Ihallgasbildung in den Schläuchen verhindert."Flame arrester for cutting torches." --------------------------------------- The present invention relates to the novel arrangement of a flame arrester for cutting torches, preferably made of a porous sintered metal. It is already known to provide a handle tube, which is used to hold a welding, cutting or soldering torch, with a built-in flame arrester made of sintered metal. However, this suggestion is likely to be inadequate, since the blowback can still get into the mixing chamber, in which explosions have already occurred. This arrangement at most prevents the formation of hall gas in the hoses.

In richtiger Erkenntnis dieses Nachteiles wird erfindunggemäss vorgeschlagen, die Flammensperre, zweckmässig aus einem porösen Sintermetall, zwischen der mischkammer und der Brenndüse an beliebiger Stelle einzubauen, UD die evtl. rückschlagende Flamme schon garnicht mehr zündfähig in die fischkammer gelangen zu lassen. Es ist erwiesen, dass Flammen oder entzündende Gase im Rückschlag beim Durchströmen einer Sintermetallsperre soviel Wärme an das poröse Medium abgeben, dass sie beim Verlassen der Sperre unter den Zündpunkt abgekühlt sind und nicht mehr weiterbrennen. Um auf diesem Wege eine unbedingt flammenlöschende und explosionshemmende Wirkung zu erzielen, muss der in der Leitung zwischen Brenner und Mischdüse sitzende Sperrkörper aus Sintermetall eine entsprechende Formgebung, z. B. trichter-rohr-oder dergl. förmig ausgebildet sein. Bei kleinen Querschnitten genügen aber auch schon scheibenförmige Sperren verschiedener Stärken.With correct recognition of this disadvantage, it is proposed according to the invention, the flame barrier, expediently made of a porous sintered metal, between the mixing chamber and the burner nozzle at any point, UD the possibly flashing back flame not at all to be ignited in the fish chamber. It is proven that flames or igniting gases in the backflow when flowing through a sintered metal barrier give off so much heat to the porous medium that it is under when leaving the barrier the ignition point have cooled down and no longer burn. In order to in this way to achieve an absolutely flame-extinguishing and explosion-inhibiting effect, the blocking element in the line between the burner and the mixing nozzle must be removed Sintered metal a corresponding shape, for. B. funnel-pipe or the like. Shaped be trained. In the case of small cross-sections, however, disk-shaped ones are sufficient Locks of various strengths.

In der beiliegenden Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt : Dieselbe zeigt : einen Schneideinsatz, teilweise im Schnitt.In the accompanying drawing, the subject matter of the invention is for example shown: The same shows: a cutting insert, partly in section.

Gemäss der Zeichnung sind 1, 2 und 3 in der Gasleitung zwischen Mischkammer und Schneiddüse eingebaute, triohter-scheiben-und rohrförmige Sperren aus porösem Sintermetall, um hauptsächlich Rückbrennungen in die mischkammer, den Handgriff und in den Sauerstoffschlauch durch Ersticken der Rückflaome v o r der Cd kammer zu verhindern.According to the drawing, 1, 2 and 3 are in the gas line between the mixing chamber and cutting nozzle built-in, triohter-disc and tubular barriers made of porous Sintered metal, mainly to prevent burn-backs in the mixing chamber, the handle and into the oxygen tube by suffocating the back fluff in front of the CD chamber to prevent.
