Description
Strahldüse. Die Erfindung betrifft eine Strahldüse, bei der die Austrittsbohrung einer der eigent lichen Düsenbohrung vorgeschalteten Kammer um soviel grösser ist als die Düsenbohrung selbst, dass die äussern Teile des die Düsen bohrung verlassenden Flüssigkeitskegels ab gefangen werden und ein geschlossener Flüs sigkeitsstrahl entsteht.
Bei bis jetzt bekannten Düsen tritt die zu zerstäubende Flüssigkeit direkt aus der Mündungsbohrung unter Bildung eines grossen Streukegels ins Freie. Sollen nun für be stimmte Zwecke ganz spitze Streukegel er zielt werden, so war dies bei diesen Aus führungen schwerlich zu erreichen.
Diesen Nachteil beseitigt die Strahldüse gemäss der Erfindung durch die eingangs erwähnte Ausbildung. Die aus der Düsen bohrung austretende, fein zerstäubte Flüssig keit wird dadurch in der Kammer zusammen gefasst und tritt dann als einheitlicher, spitzer Strahl aus dieser aus. Anderseits bietet die Kammer noch grosse Vorteile bei Herstellung von Düsen kleinster Leistung. Die Kammer wird zu diesem Zwecke so ausgebildet, dass ein grösserer Teil der aus der Düsenbohrung austretenden, fein vernebelten Flüssigkeit zurückgehalten wird und nur ein bestimmter Teil der Gesamtmenge durch die grössere Bohrung in der Kammer ins Freie gelangt. Die in der Kammer niedergeschlagene Flüs sigkeit führt man durch eine sich daran an schliessende Rohrleitung ab.
Die Kammer braucht nicht unbedingt mit dem Düsen körper ein Stück zu bilden, sondern kann auch auf diesen aufgeschraubt sein, so dass man dadurch noch eine Reguliermöglichkeit besitzt. Gegebenenfalls kann die Kammer noch mit radialen Bohrungen versehen sein, um in besonderen Fällen ein flüssiges oder gasförmiges Medium injektorartig anzusaugen, das sich dann in der Kammer mit der aus der Düsenbohrung austretenden Flüssigkeit vermischt.
Auf beiliegender Zeichnung sind ver schiedene Ausführungsbeispiele des Erfin dungsgegenstandes dargestellt. Fig. 1 zeigt eine mit einteiligem Düsen körper versehene Strahldüse im Längsschnitt; Fig. 2 stellt eine ähnliche Düse dar, aber mit aufgeschraubter Kammer; Fig. 3 zeigt eine Düse, die mit Kammer und Flüssigkeitsrückführungsleitung ausge stattet ist.
Die Strahldüse nach Fig. 1 besteht aus zwei Einzelteilen, dem Düsenkörper 1 und dem Drallkörper 2. Letzterer kann durch ein Gewinde im Düsenkörper 1 eingeschraubt werden. Die zu zerstäubende Flüssigkeit wird der Düse unter Druck durch den Anschluss stutzen 3 zugeführt. Sie muss dann den Drall körper 2 passieren und erhält durch die auf dessen Umfang eingearbeiteten Schlitze 4 eine Rotationsbewegung. Hierauf tritt sie durch die Düsenbohrung 5 in zerstäubtem Zustande in die Kammer 6 ein. Durch die Kammerbohrung 7, die einen entsprechend grösseren Durchmesser als die Düsenbohrung 5 aufweist, verlässt die Flüssigkeit in einem spitzwinkligen Kegel die Strahldüse.
In Fig. 2 ist eine ähnliche Düse darge stellt; aber in diesem Falle kann die Ent fernung der Kammerbohrung 7 von der Düsen mündungsbohrung 5 verändert werden. Der Düsenkörper ist zu diesem Zwecke mit einem Gewinde 8 versehen, auf dem der Kammer körper mehr oder weniger aufgeschraubt werden kann. Ferner ist bei dieser Ausfüh rungsform die Kammer mit radialer. Boh rungen 9 versehen, durch die vermittelst des Düsenstrahles injektorartig ein flüssiges oder gasförmiges Medium angesaugt werden kann. Fig.3 zeigt ein weiteres Ausführungs beispiel der Düse, bei dem die Kammer 6 mit einer Bohrung 10 versehen ist, an die sich eine Rücklaufleitung 11 anschliesst.
Ein Teil der aus der Düsenbohrung 5 austreten den, fein zerstäubten Flüssigkeit wird in der Kammer 6 abgeschieden und durch die Boh rung 10 und Ableitung 11 abgeführt. Je nach dein Verhältnis der Düsenbohrung 5 zur Kammerbohrung 7 kann jede gewünschte Leistung der Düse hergestellt werden.
Jet nozzle. The invention relates to a jet nozzle in which the outlet bore of a chamber upstream of the actual nozzle bore is so much larger than the nozzle bore itself that the outer parts of the cone of liquid leaving the nozzle bore are caught and a closed liquid jet is created.
In the case of nozzles known up to now, the liquid to be atomized emerges directly from the orifice bore, forming a large scatter cone into the open air. If very sharp scatter cones are to be aimed for for certain purposes, this was difficult to achieve with these designs.
The jet nozzle according to the invention eliminates this disadvantage through the design mentioned at the beginning. The finely atomized liquid emerging from the nozzle bore is concentrated in the chamber and then emerges from it as a uniform, pointed jet. On the other hand, the chamber offers great advantages in the production of nozzles with the lowest output. For this purpose, the chamber is designed in such a way that a larger part of the finely atomized liquid emerging from the nozzle bore is retained and only a certain part of the total amount is released into the open through the larger bore in the chamber. The liquid precipitated in the chamber is discharged through an adjoining pipeline.
The chamber does not necessarily need to form one piece with the nozzle body, but can also be screwed onto it, so that there is still a possibility of regulation. If necessary, the chamber can also be provided with radial bores in order, in special cases, to suck in a liquid or gaseous medium like an injector, which then mixes in the chamber with the liquid emerging from the nozzle bore.
On the accompanying drawing, various embodiments of the invention are shown ver. Fig. 1 shows a one-piece nozzle body provided with a jet nozzle in longitudinal section; Fig. 2 shows a similar nozzle, but with the chamber screwed on; Fig. 3 shows a nozzle which is equipped with a chamber and liquid return line.
The jet nozzle according to FIG. 1 consists of two individual parts, the nozzle body 1 and the swirl body 2. The latter can be screwed into the nozzle body 1 through a thread. The liquid to be atomized is fed to the nozzle under pressure through the connector 3. It then has to pass the swirl body 2 and is given a rotational movement by the slots 4 incorporated on its circumference. It then enters the chamber 6 through the nozzle bore 5 in the atomized state. Through the chamber bore 7, which has a correspondingly larger diameter than the nozzle bore 5, the liquid leaves the jet nozzle in an acute-angled cone.
In Fig. 2 a similar nozzle is Darge provides; but in this case the Ent distance of the chamber bore 7 from the nozzle orifice bore 5 can be changed. The nozzle body is provided for this purpose with a thread 8, on which the chamber body can be screwed more or less. Furthermore, in this embodiment, the chamber with radial. Boh stanchions 9 provided, through which a liquid or gaseous medium can be sucked in by means of the nozzle jet like an injector. 3 shows a further embodiment example of the nozzle in which the chamber 6 is provided with a bore 10 to which a return line 11 is connected.
Part of the exiting from the nozzle bore 5, the finely atomized liquid is deposited in the chamber 6 and tion through the Boh 10 and discharge line 11 discharged. Depending on your ratio of the nozzle bore 5 to the chamber bore 7, any desired output of the nozzle can be produced.
