Abstract

The atomiser for paint and other materials, has a Venturi channel in a socket (6) between the inlet nozzle (8) for the compressed high pressure air, and the air head (1) with its branch line (4) for the paint supply. The socket has a divergent cone (5) on the head side of the socket and a convergent cone (7) on the side of the air inlet nozzle, the former being larger than the latter.

Description

Niederdruckzerstäuber Low pressure atomizer

Die Erfindung hat als Gegenstand eine Verbesserung eines Gerätes zum Zerstäuben von Farbe und anderen FlüssigkeitenO Die derzeitigen Spritzpistolen arbeiten mit auf Hochdruck verdichteter Luft (3+ - 4 kg per cm2). Das am Luftkopf durch Druckluft ankommende Spritzmaterial wird zerstäubt und bildet Dämpfe und Nebel, welche fUr den BenUtzer und seine Umgebung schädlich und störend sind, sowie auch grösseren Materialverbrauch dadurch erfordern.The invention has as an object to improve a device for Atomizing Paint and Other Liquids o Current spray guns work with air compressed to high pressure (3+ - 4 kg per cm2). That at the air head by compressed air Incoming spray material is atomized and forms vapors and mist, which for are harmful and disruptive to the user and his environment, as well as larger ones Require material consumption thereby.

Dieser hier zum Patent angemeldete Spritzkopf vermeidet all diese Nachteile, indem er mit vermindertem Druck, jedoch mit grossem Luftvolumen, das wie ein Luftmantel das Spritzmaterial umschliesst, RUckprall und Nebelbildung vermeidet und so auch zur Einsparung von Spritzmaterial beiträgt Bei diesem Gerät befindet sich zwischen der ZerstäubungsdUse, der Materialzufuhr einerseits und der Druckluftzufuhr andererseits, eine Venturi-DUseO Die Druckluft kommt dadurch an die ZerstöubungsdUse mit vermindertem oder schwachem Druck, jedoch mit viel grösserem Volumen, -sodass diese Luftausströmungsmenge von der Druckluft geliefert, mit 4-5 multipliziert werden kann. Die Projektiontdes Materials ist fast ohne Nebel, die Kosten fUr Druckluft und Mbter£ql wesentlich geringer.This spray head for which a patent is pending avoids all of these Disadvantages in that it is operated with reduced pressure, but with a large volume of air, the how an air jacket surrounds the spray material, avoids rebound and mist formation and thus also helps to save spray material. This device is located between the atomizing nozzle, the material supply on the one hand and the compressed air supply on the other hand, a Venturi-DUseO The compressed air comes through this to the atomizing nozzle with reduced or weak pressure, but with a much larger volume, -so that this air flow rate supplied by the compressed air must be multiplied by 4-5 can. The projection of the material is almost without fog, the cost of compressed air and Mbter £ ql much less.

Die beigefügte, numerierte Zeichnung vermittelt eine bevorzugte Ausführungsart und der aufgezeigte Querschnitt macht ohne Schwierigkeit den Sinn der Erfindung verständlich.The attached numbered drawing shows a preferred embodiment and the cross section shown makes the sense of the invention without difficulty understandable.

Die Spritzpistole besteht, wie bei anderen Geräten, aus einem Spritzkopf 1, einer Zerstäubungsdüse 2, einer ringförmigen Kammer 3, in welche der Materialeinlass 4 mündet.As with other devices, the spray gun consists of a spray head 1, an atomizing nozzle 2, an annular chamber 3 into which the material inlet 4 opens.

In den Hintergrund der Rundkammer 3 mUndet der auseinandergehende Konus 5 der Venturi-Trompe 6, deren anderes Ende aus einem konvergierenden Konus 7 besteht, in welchen einerseits durch eine DUse 8 Hochdruckluft und andererseits durch eine Zufuhr 9 mit Bohrungen 10 versehen, atmosphärische Luft in den Körper des Gerätes geführt wird0 Man versteht somit, dass die Hochdruckluft, durch die FUhrung 11 ankommend und durch die DUse 8 geführt, reduziert wird, dank der zusätzlichen atmosphärischen Luft durch den Kanal 9 und auf einen viel niedrigeren Druck am Ausgang des divergierenden Konus der Venturi-Trompe 6 gebracht wird.The diverging one opens into the background of the round chamber 3 Cone 5 of the Venturi trompe 6, the other end of which consists of a converging cone 7 consists in which on the one hand through a DUse 8 high pressure air and on the other hand provided with bores 10 through a supply 9, atmospheric air into the body of the device0 It is thus understood that the high pressure air through which Guide 11 arriving and guided through the nozzle 8, is reduced, thanks to the additional atmospheric air through duct 9 and to a much lower pressure at the outlet the diverging cone of the Venturi trompe 6 is brought.

Es ist also möglich einen Spritzkopf zu benUtzen, der durch die in seinem Körper befindliche Venturi-Trompe mit Niederdruck und grossem Luftvolumen funktionniert.It is therefore possible to use a spray head that is driven by the in Venturi trompe located on his body with low pressure and large air volume works.
