Verstellbare Streudüse. Patentiert im Deutschen Reiche vom 22. August 1912 ab. Adjustable spray nozzle. Patented in the German Empire on August 22, 1912.
Gegenstand der Erfindung ist eine Streudüse, bei der die Feinheit der Zerstäubung, der Flüssigkeitsverbrauch und die Größe des Streukegels regelbar sind und die auch bei Anwendung von nur einem schraubenförmig verlaufenden Kanal die Flüssigkeit gleichmäßig auf den Umfang des Streukegels verteilt.The invention relates to a scattering nozzle in which the fineness of the atomization, the Liquid consumption and the size of the scatter cone are adjustable and also when used the liquid is distributed evenly by just one helical channel distributed over the circumference of the scattering cone.
Dies wird erreicht durch einen als Anschlußstück an die Flüssigkeitszuleitung dienenden Körper, der in einen Kegel mit den schraubenförmig verlaufenden Kanälen ausläuft und von einer auf ihm verstellbar angeordneten Zerstäuberhaube umschlossen wird, die sich in der Schlußstellung an den Kegel anlegt und aufThis is achieved by a serving as a connection piece to the liquid supply line Body that ends in a cone with the helical channels and from an adjustable atomizer hood is enclosed on it, which is located in the Final position on the cone and on
1S der Innenseite bei der Mündung einen zur Längsachse der Düse senkrechten Absatz hat. Ein Ausführungsbeispiel ist in Fig. ι im Schnitt und in Fig. 2 in Draufsicht bei abgenommener Zerstäuberhaube dargestellt. 1 S of the inside at the mouth has a shoulder perpendicular to the longitudinal axis of the nozzle. An embodiment is shown in Fig. Ι in section and in Fig. 2 in plan view with the atomizer hood removed.
Der als Anschlußstück an die Flüssigkeitszuleitung dienende Körper α läuft in einen Kegel b mit den schraubenförmig verlaufenden Kanälen c aus. Gegen diesen Kegel b legt sich in der Schlußstellung die durch Gewinde verstellbare Zerstäuberhaube e. Die unter Druck eintretende Flüssigkeit kann also bei dieser Stellung der Haube e nur durch die schraubenförmig verlaufenden, halbrunden Kanäle c der Düsenöffnung d zuströmen; dabei nimmt die Flüssigkeit eine drehende Bewegung an und wird nach ihrem Austritt aus der Düse d zufolge der Fliehkraft auseinandergeworfen und fein zerstäubt. The body α serving as a connection piece to the liquid feed line ends in a cone b with the helically extending channels c. In the final position, the atomizer hood e, which can be adjusted by means of a thread, rests against this cone b. In this position of the hood e , the liquid entering under pressure can only flow into the nozzle opening d through the helical, semicircular channels c; in the process, the liquid assumes a rotating movement and, after it emerges from the nozzle d , is thrown apart and finely atomized as a result of the centrifugal force.
Stellt man nun durch Abschrauben der Zerstäuberhaube e zwischen dem Kegel b und dem Hohlkegel der Zerstäuberhaube e einen Abstand her, so strömt die Flüssigkeit auch rings um den Kegel b durch den entstandenen Zwischenraum der Düsenöffnung zu Da jedoch die Kanäle c den größten Teil der Flüssigkeit mitführen, so wird die durch den Zwischenraum der Düsenöffnung gerade zustrebende Flüssigkeit mitgerissen und ebenfalls in drehende Bewegung versetzt. Die Drehgeschwindigkeit der durchströmenden Flüssigkeit hängt natürlich vom Abstand zwischen dem Kegel b und dem Hohlkegel der Zerstäubertrommel e ab. Demgemäß ändert sich auch die Feinheit der Zerstäubung und die Größe des Streukegels bei Veränderung des Abstandes der Haube vom Kegel. Es wird also bei großem Abstand viel langsam sich drehende und deshalb grob zerteilte, bei kleinem Abstand wenig schnell sich drehende und fein zerstäubte Flüssigkeit in einem jeweils ihrer Fliehkraft entsprechenden spitzen oder stumpfen Streukegel aus der Düse austreten.If you now create a distance between the cone b and the hollow cone of the atomizer hood e by unscrewing the atomizer hood e , the liquid also flows around the cone b through the gap between the nozzle opening, however, since the channels c carry most of the liquid with them , the liquid which is just moving through the gap between the nozzle opening is entrained and also set in rotating motion. The speed of rotation of the liquid flowing through depends of course on the distance between the cone b and the hollow cone of the atomizer drum e . Accordingly, the fineness of the atomization and the size of the scattering cone also change when the distance between the hood and the cone is changed. So at a large distance, much slowly rotating and therefore coarsely divided, at a small distance not very fast rotating and finely atomized liquid will emerge from the nozzle in a pointed or blunt cone corresponding to its centrifugal force.
Diese Verstellbarkeit der Zerstäuberhaube e ermöglicht des weiteren ein reinigendes Durchspülen des Zerstäubers während des Betriebes.This adjustability of the atomizer hood e also enables a cleaning flushing of the atomizer during operation.
Der auf der Innenseite der Zerstäuberhaube e bei der Düsenöffnung d senkrecht zur Längsachse der Düse angeordnete Absatz hat den Zweck, die Flüssigkeitsstrahlen, die zufolge ihrer Trägheit die drehend ansteigende Riehtung, die sie in den schraubenförmig verlau-The paragraph arranged on the inside of the atomizer hood e at the nozzle opening d perpendicular to the longitudinal axis of the nozzle has the purpose of the liquid jets, which, due to their inertia, cause the rotating ascending direction which they run in the helical shape.
fenden Kanälen c angenommen haben, fortsetzen, vor ihrem Austritt in eine zur Zerstäuberachse senkrecht stehende Drehebene überzuleiten, um eine gleichmäßige Verteilung der Flüssigkeit auf den ganzen Umfang des Streukegels zu erhalten. Dies ist hauptsächlich dann nötig, wenn der Zerstäuber, um auf eine Mindestleistung bei möglichst weiten Wasserdurchgängen zu kommen, nur mit einem ίο schraubenförmig verlaufenden Kanal ausgerüstet ist.fenden channels c have assumed, continue before their exit in one to the atomizer axis vertical plane of rotation to transfer the liquid over the entire circumference of the To get scatter cones. This is mainly necessary when the atomizer is in order To get a minimum performance with the largest possible water passages, only with one ίο helical channel is equipped.
