Description
Die Erfindung betrifft einen Schweiß- und Schneidbrenner, wie er z. B. zum autogenen Schweißen verwendet wird. Gewöhnlich werden diese Schweißbrenner mit einem Azetylen-Sauerstoff-Gemisch betrieben, doch macht besonders zur Zeit die Beschaffung von Karbid gewisse Schwierigkeiten. Die Erfindung hat sich daher dieAufgabe gestellt, einen Schweiß- und Schneidbrenner zu schaffen, der statt mit Azetylen bzw. Karbid und Sauerstoff mit einem flüssigen Brennstoff, besonders Benzin und Sauerstoff, arbeiten kann.The invention relates to a welding and cutting torch as it is, for. B. is used for oxy-fuel welding. Usually these are welding torches operated with an acetylene-oxygen mixture, but it makes the Obtaining carbide certain difficulties. The invention therefore has the object asked to create a welding and cutting torch that instead of acetylene or carbide and oxygen with a liquid fuel, especially gasoline and Oxygen, can work.
Gemäß der Erfindung wird vorgeschlagen; vor der Brennerdüse des Schweiß- und Schneidbrenners eine vorgewärmte Gaskammer anzuordnen, in welcher der hineingeleitete flüssige Brennstoff, z. B. Benzin, vergast wird. Erfindungsgemäß ist für die Vorwärmung der Gaskammer ein besonderer Hilfsbrenner vorgesehen, der zweckmäßigerweise ebenfalls mit Benzin gespeist wird: An Hand der Zeichnung wird ein Ausführungsbeispiel der Erfindung beschrieben.According to the invention it is proposed; in front of the torch nozzle of the welding and cutting torch to arrange a preheated gas chamber into which the is directed liquid fuel, e.g. B. gasoline is gasified. According to the invention is for preheating the gas chamber is provided with a special auxiliary burner, which is also expediently is fed with gasoline: Based on the drawing, an embodiment of the Invention described.
Fig. i zeigt eine Seitenansicht des erfindungsgemäßen Schneidbrenners; Fig. 2 zeigt den Schneidbrenner von oben.Fig. I shows a side view of the cutting torch according to the invention; Fig. 2 shows the cutting torch from above.
Der mit einer üblichen Brennerdüse i ausgestattete Schweiß- und Schneidbrenner ist mit einem besonderen Hilfsbrenner 2 in Form eines Lötlampenbrenners ausgestattet, mit dem der Gasbrenner 3 erwärmt wird. Die Benzinleitung 9 wird durch den Handgriff 4 sowohl zum Hilfsbrenner 2 als auch zum Gasbrenner 3 geführt. Das Benzin strömt durch die Brennstoffdüse 5 in die vorgewärmte Gaskammer 6 und wird dort vergast. Das im Brenner selbst erzeugte Gas strömt dann durch die Mischdüse 7, der über die Leitung 8 Sauerstoff zugeführt wird. Das Gasgemisch strömt an der Brennerspitze i zur Verbrennung aus.The welding and cutting torch equipped with a standard torch nozzle is equipped with a special auxiliary torch 2 in the form of a blowtorch torch, with which the gas burner 3 is heated. The fuel line 9 is through the handle 4 both to the auxiliary burner 2 and to the gas burner 3. The gasoline flows through the fuel nozzle 5 into the preheated gas chamber 6 and is gasified there. The gas generated in the burner itself then flows through the mixing nozzle 7, which is via the Line 8 oxygen is supplied. The gas mixture flows at the burner tip i to burn off.
Der über die Leitung 8 zugeführte Sauerstoff wird erst an der Mischdüse 7 zugeführt, um eine vorzeitige Überhitzung zu vermeiden. Die Regulierung der Vorwärmflamme des Hilfsbrenners 2 erfolgt durch das Ventil io, während zur Regelung der Sauerstoffzufuhr das Ventil i i und zur Regelung der Benzinzufuhr für den Brenner 3 das Ventil 12 dient.The oxygen supplied via line 8 is only released at the mixing nozzle 7 to avoid premature overheating. Regulation of the preheating flame of the auxiliary burner 2 takes place through the valve io, while regulating the oxygen supply the valve i i and for regulating the fuel supply for the burner 3, the valve 12 serves.
