Description

Otto Heinrich in Leipzig Spritzapparat Otto Heinrich in Leipzig spray gun

Patentiert im Deutschen Reiche vom 8. Juli 1930 abPatented in the German Empire on July 8, 1930

Vorliegende Erfindung besteht darin, daß die zur Spritzdüse geführte erwärmte Preßluft zuvor in einen Heißluftzylinder geleitet wird, welcher mitten im Farbbehälter so angeordnet ist, daß in dessen Inneren: sich das Farbsteigrohr befindet; Durch diese Anordnung wird die Farbe, welche sich im Farbbehälter befindet, vorgewärmt, so daß sie im dünnflüssigen Zustande der Zerstäu-The present invention consists in that the heated one led to the spray nozzle Compressed air is previously passed into a hot air cylinder, which is in the middle of the paint container is arranged so that in its interior: there is the paint riser pipe; Through this arrangement the paint, which is in the paint container, is preheated so that they in the thin liquid state of the atomization

xo berdüse zufließt. Bei den bekannten Zerstäubern dieser Art wird im allgemeinen die Heißluft mantelförmig um den in der Spritzpistole liegenden Farbkanal zur Düse geleitet. xo over nozzle flows in. In the known atomizers of this type is generally the Hot air is passed around the paint channel in the spray gun to the nozzle in the form of a jacket.

Hierbei findet nur eine einseitige Wärmeübertragung statt, während die nach außen liegende Seite des Mantels unwirksam bleibt und Wärmeverluste unvermeidlich macht.
Bei vorliegender Erfindung wird die Farbe nach beiden Richtungen von der Heißluft' erwärmt, und es kann keine erhebliche Abkühlung durch die Außenluft eintreten. .
Beiliegende Zeichnung stellt ein Ausführungsbeispiel dar.Here, only one-sided heat transfer takes place, while the outward-lying side of the jacket remains ineffective and makes heat losses inevitable.
In the present invention, the paint is heated in both directions by the hot air, and there can be no significant cooling by the outside air. .
The accompanying drawing shows an exemplary embodiment.

Die Luft wird, wie bekannt, durch einen Lufterhitzer außerhalb des Spritzapparates angewärmt und tritt in den Zugang 8 durch das Absperrorgan 2 und durch das Eintrittsrohr 5 in den Heißluftzylinder 4 ein. Das Rohr hat den Zweck, die eingeführte erhitzte Luft innerhalb des Heißluftzylinders 4' bis nach unten zu führen, wodurch die Gewähr gegeben ist, daß der Heißluftzylinder 4 in seiner ganzen Länge gleichmäßig erwärmt wird. Der Heißluftzylinder 4 gibt die zugeführte Wärme nach innen durch! das Farblacksteigrohr 9 und nach außen nach dem Färb- und Lackbehälter 3 ab. Hierdurch wird das Farbmaterial, besonders das, welches sich jeweilig im Steigrohr 9 befindet und verspritzt werden soll, erwärmt und in diesem Zustande der Farbdüse zugeführt. Nachdem die Heißluft den Weg durch den Heißluftzylinder 4 gemacht hat, tritt sie durch den Kanal 6 in die Luftdüse 7 ein und erwärmt den gesamten Düsenkopf.The air is, as is known, through an air heater outside the spray gun warmed and enters the access 8 through the shut-off device 2 and through the inlet pipe 5 into the hot air cylinder 4. The purpose of the tube is to heat the imported one Air inside the hot air cylinder 4 'to lead down, whereby the guarantee it is given that the hot air cylinder 4 is heated uniformly over its entire length will. The hot air cylinder 4 passes the supplied heat to the inside! the paint riser pipe 9 and to the outside after the paint and varnish container 3. This will make the color material, especially what is located in the riser 9 and is to be sprayed, heated and in supplied to the paint nozzle in this state. After the hot air has made its way through the Has made hot air cylinder 4, it enters the air nozzle 7 through the channel 6 and heats the entire nozzle head.
