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.
