abgeschlossene Kammer strömt.closed chamber flows.
Die Erfindung bezieht sich auf eine Streudüse, insbesondere zum Zerstäuben von Flüssigkeiten, bei der die Flüssigkeit tangential in eine vor der Düsenöffnung liegende, abgeschlossene Kammer strömt, um die Flüssigkeit vor ihrem Austritt aus der Düsenöffnung in eine möglichst schnelle Umdrehung zu versetzen. The invention relates to a scattering nozzle, in particular for atomizing liquids, in which the liquid tangentially enters a closed one in front of the nozzle opening Chamber flows in order to make the liquid rotate as fast as possible before it emerges from the nozzle opening.
Von den bekannten Streudüsen dieser ArtFrom the known sprinkler nozzles of this type
ίο unterscheidet sich die vorliegende dadurch, daß der vor der Düsenöffnung liegende zylindrische Kammerhohlraum hinten durch einen von außen verschiebbaren Kolben abgeschlossen ist, und die tangentialen Einströmkanäle, die vorn kurz hinter der Düsenöffnung in die Kammer münden, zusammen einen kleineren oder gleichen Querschnitt wie die Düsenöffnung haben. Durch diese Anordnung wird erreicht, daß die Flüssigkeit mit hoher Geschwindigkeit ohne Gegendruck in der Kammer umläuft, also mit hoher Eigengeschwindigkeit und unter entsprechend großem Streuwinkel aus der Düsenöffnung heraustritt, und daß der Streuwinkel durch Verschieben des Kolbens regelbar ist, indem die der umlaufenden Flüssigkeit als Reibungsfläche sich darbietende zylindrische Kammerwandung durch Vor- und' Zurückschieben des Kolbens verringert oder vergrößert wird. Dabei wird durch Verringerung , der Reibungsfläche eine erhöhte und durch Vergrößerung eine verringerte Umlaufgeschwindigkeit der Flüssigkeit erhalten, woraus sich eine Vergrößerung oder Verringerung des Streuwinkels ergibt, ohne daß der Flüssigkeitsdruck zu diesem Zwecke verändert werden müßte. Infolgedessen kann die Regelung der Streu wirkung bei stets gleichbleibenden Mengen der austretenden, zerstäubten Flüssigkeit erfolgen.ίο the present differs in that that lying in front of the nozzle opening cylindrical chamber cavity through a rear externally displaceable piston is completed, and the tangential inflow channels, which open into the chamber at the front just behind the nozzle opening, together have a smaller or the same cross-section as the Have nozzle opening. This arrangement ensures that the liquid with high Speed without counterpressure in the chamber, i.e. with high own speed and emerges at a correspondingly large scattering angle from the nozzle opening, and that the scattering angle by moving the The piston can be regulated by the fact that the circulating fluid presents itself as a friction surface cylindrical chamber wall reduced by pushing the piston back and forth or enlarged. By reducing the friction surface, the friction surface is increased and by enlarging it is decreased Circulation speed of the liquid obtained, resulting in an enlargement or Reducing the scattering angle results without reducing the fluid pressure for this purpose would have to be changed. As a result, the control of the scattering effect can always remain the same Quantities of the escaping, atomized liquid take place.
Auf der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. Fig. 1 zeigt die eine Ausführungsform der Streudüse im Längsschnitt, Fig. 2 eine Vorderansicht des die Kammer bildenden Einsatzes gemäß einem Schnitt nach A-B der Fig. 1; Fig. 3 zeigt die zweite Ausführungsform im Längsschnitt des vorderen Düsenteils, während Fig. 4 und 5 Ansichten der beiden den Kammerkörper nach Fig. 3 bildenden Teile darstellen. Two exemplary embodiments of the invention are shown in the drawing. 1 shows the one embodiment of the scattering nozzle in longitudinal section; FIG. 2 shows a front view of the insert forming the chamber according to a section according to AB in FIG. 1; 3 shows the second embodiment in longitudinal section of the front nozzle part, while FIGS. 4 and 5 show views of the two parts forming the chamber body according to FIG.
Bei der Ausführungsform der Düse nach Fig. ι und 2 liegt in einem Rohr α, dem die Flüssigkeit durch einen seitlichen Rohransatz b zugeleitet wird, eine Spindel c, die am hinteren Ende mit Schraubengewinde versehen ist. Letzteres ist in einer das Rohr α hinten verschließenden Schraubenmutter d an einem gerändelten Knopf e drehbar.In the embodiment of the nozzle according to FIGS. 1 and 2, a spindle c, which is provided with a screw thread at the rear end, lies in a tube α to which the liquid is fed through a lateral tube attachment b. The latter can be rotated on a knurled knob e in a screw nut d closing the tube α at the rear.
Der Düsenkopf wird durch einen auf das Rohr α gesteckten Stutzen f gebildet, der in seinem vorderen Teile einen rohrartigen Einsatzkörper g aufnimmt. Dieser Einsatzkörper ruht mit einem Flansch auf einem inneren Absatze des Stutzens f und besitzt auf seiner Vorderseite zwei Einströmkanäle h, .die von zwei am Umfange des Flansches befindlichen,The nozzle head is formed by a connector f which is placed on the tube α and which receives a tube-like insert body g in its front part. This insert body rests with a flange on an inner shoulder of the connecting piece f and has two inflow channels h on its front side, the two of which are located on the periphery of the flange.
mit den Innenräumen des Stutzens f und des Rohres α in Verbindung stehenden Verbindungskanälen k ausgehen und nach innen tangential in den zylindrischen Kammerhohlraum i münden. Vor dem Einsatzkörper g liegt eine Scheibe I, in der sich die Düsenöffnung m befindet und die durch eine Schraubenmuffe η auf dem ßtutzen f gehalten wird. Der zylindrische Kammerhohlraum i wirdwith the interiors of the nozzle f and the tube α connected connecting channels go out and open tangentially inward into the cylindrical chamber cavity i. In front of the insert body g there is a disk I in which the nozzle opening m is located and which is held on the nozzle f by a screw sleeve η. The cylindrical chamber cavity i becomes
ίο hinten durch die als Kolben wirkende Spindel c abgeschlossen.ίο closed at the rear by the spindle c acting as a piston.
Die durch den Rohransatz b unter Druck in das Rohr α und den Stutzen f eingeführte Flüssigkeit tritt durch die engen Einströmkanäle h tangential mit hoher Geschwindigkeit in den Kammerhohlraum i, und da der Querschnitt der Düsenöffnung m ebenso groß oder größer ist als der Gesamtquerschnitt der tangentialen Kanäle h, so findet die in den Kammerhohlraum eintretende Flüssigkeit dort keinen Druckwiderstand vor. Infolge der dadurch bedingten hohen Umlaufgeschwindigkeit besitzt die aus der Düsenöffnung austretende Flüssigkeit starke Fliehkraft, die bewirkt, daß die Flüssigkeit in Form eines sehr dünnwandigen, weitwinkligen Kegelmantels ausströmt, der sich in kurzer Entfernung von der Düse in einen feinen Nebel auflöst.The liquid introduced under pressure through the pipe extension b into the pipe α and the nozzle f enters the chamber cavity i tangentially through the narrow inflow channels h at high speed, and since the cross-section of the nozzle opening m is as large or larger than the total cross-section of the tangential channels h, the fluid entering the chamber cavity is there before any pressure resistance. As a result of the resulting high circulation speed, the liquid emerging from the nozzle opening has a strong centrifugal force, which causes the liquid to flow out in the form of a very thin-walled, wide-angled conical shell, which dissolves into a fine mist at a short distance from the nozzle.
Die Spindel c kann durch Drehen mittels des Knopfes β vor- und zurückbewegt werden, wodurch eine Verringerung oder Vergrößerung des Kammerhohlraumes i erzielt wird. Das vordere Ende der Spindel kann, wie dargestellt, kegelförmig zugespitzt sein, so daß durch die Spindel gleichzeitig die Düsenöffnung im Querschnitt geändert oder gänzlich verschlossen werden kann.The spindle c can be moved back and forth by turning the button β , whereby a reduction or enlargement of the chamber cavity i is achieved. The front end of the spindle can, as shown, be tapered so that the nozzle opening can be changed in cross section or completely closed by the spindle at the same time.
Die Düse bietet somit die Möglichkeit, durch einfaches Drehen der Spindel die Streuwirkung in weiten Grenzen zu regeln.The nozzle thus offers the possibility of the spreading effect by simply turning the spindle to be regulated within wide limits.
Wie die Ausführungsform der Düse nach Fig. 3 bis 5 zeigt, können die tangentialen Einströmkanäle h auch in der Kopfscheibe I (Fig. 5) angeordnet sein, wobei dann der zylindrische Kammerhohlraum i zweckmäßig von dieser Kopfscheibe und einer dahinter gelagerten ringförmigen Scheibe 0 (Fig. 4) gebildet wird, die am Umfange die Verbindungskanäle k besitzt.As the embodiment of the nozzle according to FIGS. 3 to 5 shows, the tangential inflow channels h can also be arranged in the head disk I (FIG. 5), in which case the cylindrical chamber cavity i is expediently made up of this head disk and an annular disk 0 mounted behind it (FIG . 4) is formed, which has the connection channels k on the circumference.
