Description
Zerstäubungsdüse. ixegenstand vorliegender Erfindung ist eine Zerstäubungsdüse für Flüssigkeiten, bei der zentral vor der Mündungsbohrung ein Umlaufraum vorgesehen ist, in welchen die Flüssigkeit durch tangential einmündende Kanäle eintritt, die auf der Stirnfläche eines mit Schraubengewinde versehenen Körpers eingefräst sind. Zweckmässigerweise sind in einen zylindrischen Ansatz des mit Ge winde versehenen Körpers radiale Schlitze eingefräst, die als Filter gegen Unreinig- keiten wirken und vor den in der Stirnfläche dieses Körpers eingefrästen Kanälen liegen.
Der Erfindungsgegenstand ist auf der Zeichnung in einem Ausführungsbeispiel ver anschaulicht.
Fig. 1 stellt einen Längsschnitt durch die Düse dar; Fig. 2 zeigt einen Querschnitt nach Linie 1-1 der Fig. 1; Fig. 3 zeigt einen Querschnitt nach Linie 11-11 der Fig. 1. Die Düse besteht aus einem Düsenkopf r1 und einem ein Schraubengewinde tragenden Körper B mit einem Gewindestutzen J. Die zu zerstäubende Flüssigkeit wird der Düse durch die Bohrung H unter Druck zugeführt. Von da aus gelangt sie durch radiale Bohrun. gen G in den zwischen Düsenkopf A und Gewindekörper B gebildeten Ringraum R.
Daraufhin muss sie die feinen Filterschlitze F passieren und gelangt dann in die Umlenk- kanäle E. Letztere sind auf der Stirnfläche des Gewindekörpers B so eingefräst, dass sie tangential in den zentral vor der Mündungs bohrung C liegenden, zylindrischen Umlauf raum D des Düsenkopfes einmünden, wodurch die Flüssigkeit in rotierende Bewegung ver setzt wird. Die dadurch mit hoher Drehzahl umlaufende Flüssigkeit verlässt die Düse durch die Bohrung C im Düsenkopf A. und wird sofort beim Austritt aus der Bohrung C in feinste Teilchen zerstäubt.
Fig. 2 zeigt die Anordnung der Umlerik- kanäle E im Grundriss. Hieraus lässt sich ersehen, dass die Umlenkkanäle E, durch die tangentiale Einmündung in den Umlaufraum D, die Flüssigkeit in eine rotierende Be wegung überführen.
Fig.3 zeigt die Anordnung der Filter schlitze F auf dem Gewindekörper B. Die Schlitze h' werden zweckmässig so ausgeführt, dass sie kleinere Durcbgangsguerschnitte auf weisen als die Umlenkkanäle E und die Düsenbohrungen C, wodurch erreicht wird, dass eventuelle Unreinigkeiten (feste Körper, Schwebestoffe, Fasern, Rost) durch die Schlitze F zurückgehalten werden und so ein dauernd einwandfreies Arbeiten der Düse gewährleistet wird.
Wenn eine Reinigung erforderlich ist, braucht nur der- Düsenkopf A abgeschraubt zu werden, wodurch dann die Schlitze F zur Reinigung frei liegen.
Atomizing nozzle. The subject of the present invention is an atomizing nozzle for liquids, in which a circumferential space is provided centrally in front of the orifice bore, into which the liquid enters through tangentially opening channels which are milled on the end face of a screw-threaded body. Expediently, radial slots are milled into a cylindrical extension of the threaded body, which act as a filter against impurities and lie in front of the channels milled into the end face of this body.
The subject of the invention is illustrated in the drawing in one embodiment.
Fig. 1 shows a longitudinal section through the nozzle; Fig. 2 shows a cross section along line 1-1 of Fig. 1; 3 shows a cross section along line 11-11 of FIG. 1. The nozzle consists of a nozzle head r1 and a body B carrying a screw thread with a threaded connector J. The liquid to be atomized is fed to the nozzle through the bore H under pressure. From there it goes through radial drilling. gen G into the annular space R formed between the nozzle head A and the threaded body B
It then has to pass through the fine filter slits F and then enters the deflection channels E. The latter are milled into the face of the threaded body B so that they open tangentially into the cylindrical circumferential space D of the nozzle head located centrally in front of the orifice bore C whereby the liquid is set in rotating motion. The liquid circulating at high speed as a result leaves the nozzle through the bore C in the nozzle head A. and is atomized into very fine particles as soon as it emerges from the bore C.
Fig. 2 shows the arrangement of the Umlerik- channels E in plan. It can be seen from this that the deflection channels E, through the tangential confluence into the circulation space D, transfer the liquid into a rotating movement.
3 shows the arrangement of the filter slots F on the threaded body B. The slots h 'are expediently designed so that they have smaller through-sections than the deflecting channels E and the nozzle bores C, which means that any impurities (solid bodies, Suspended matter, fibers, rust) are held back by the slots F, thus ensuring that the nozzle works continuously.
If cleaning is required, the nozzle head A only needs to be unscrewed, which then exposes the slots F for cleaning.
