Description

Die bekannten Drallkörperdüsen, bei denen die durch einen Drallkörper innerhalb des Düsenkörpers in eine kreisende Bewegung versetzte Flüssigkeit durch ein vorgesetztes Düsenplättchen oder Düsenmundstück kegelförmig versprüht wird, arbeiten nur unter relativ hohem Druck befriedigend. Der kegelförmige Strahl besprüht entweder eine große Fläche als Hohlkegel oder eine sehr kleine Fläche als Vollkegel. Beim praktischen Einsatz sind deswegen zur Erfassung einer großen Sprühfläche eine große Anzahl von Düsen erforderlich, wenn die Brühverteilung auf der Fläche nicht ungleichmäßig sein soll.The well-known swirl body nozzles, in which the swirl body liquid set in a circular motion within the nozzle body an attached nozzle plate or nozzle mouthpiece is sprayed in a conical shape, only work satisfactorily under relatively high pressure. The cone-shaped jet sprays either a large area as a hollow cone or a very small area as a full cone. In practical use, a large spray area is therefore required to cover a large spray area large number of nozzles required if the brewing distribution on the surface is not should be uneven.

Demgegenüber wird gemäß der Erfindung eine Drallkörperdüse ohne Düsenplättchen oder Düsenmundstück verwendet, die einen senkrecht zur Düsenachse ablaufenden, fein verteilten Brühfächer ergibt. Dieser kommt dadurch zustande, daß der konische Drallkörper saugend in dem konischen Düsenkörper anliegt und daß sowohl Düsenkörper als auch Drallkörper in einer senkrecht zur Düsenachse liegenden Ebene abschneiden und der Drallkörper einen besonders ausgebildeten Brühedurchlaß aufweist. Dieser auf der äußeren Mantelfläche des Drallkörpers schraubengangförmig eingeschnittene Brühedurchlaß hat ein dreieckiges Profil, dessen untere Dreieckseite etwa senkrecht zur Düsenachse verläuft, also in einer radial zur Düsenachse liegenden Kante an der Düsenkörpermündung ausläuft.In contrast, according to the invention, there is a swirl body nozzle without a nozzle plate or nozzle mouthpiece used, which runs perpendicular to the nozzle axis, fine distributed brewing compartments results. This comes about because the conical swirl body suction rests in the conical nozzle body and that both nozzle body and Cut off the swirler in a plane perpendicular to the nozzle axis and the Swirl body has a specially designed brewing passage. This on the outer circumferential surface of the swirl body, helically incised brewing passage has a triangular profile, the lower side of the triangle approximately perpendicular to the nozzle axis runs, that is, in an edge lying radially to the nozzle axis on the nozzle body opening expires.

Die Zentripetalbeschleunigung löst die in dieser schraubengangförmigen Nut hochsteigende Flüssigkeit in Form eines ebenen, senkrecht zur Achse liegenden, halbkreisförmigen Schleiers sehr feiner Verteilung ab. In der Zeichnung ist eine Düse nach der Erfindung in einem Ausführungsbeispiel dargestellt. Es zeigt Abb. r einen Schnitt durch die Düse, Abb. 2 eine Draufsicht und Abb. g das Profil der eingeschnittenen Nut.The centripetal acceleration resolves the helical shape in this Groove rising liquid in the form of a flat, perpendicular to the axis, semicircular veil of very fine distribution. In the drawing is one Nozzle according to the invention shown in one embodiment. It shows fig. r a section through the nozzle, Fig. 2 a plan view and Fig. g the profile of the incised groove.

In den Abbildungen ist mit r der konische Drallkörper bezeichnet, der in den Düsenkörper 2 eingesetzt ist. Der Düsenkörper 2 ist mittels Gewinde auf den Zuleitungsstutzen 3 aufgeschraubt. In den Drallkörper r ist eine schraubengangförmige Nut ¢ eingedreht, deren Profil aus Abb. 3 ersichtlich ist. Der Düsenkörper 2 und der Drallkörper t enden zusammen in einer ebenen Fläche, die senkrecht zur Düsenachse liegt. Durch den damit erzielten besonderen Auslauf der schraubengangförmigen Nut, wird ein fächerförmiger Austritt der feinzerstäubten Brühe erzielt.In the figures, r denotes the conical swirl body, which is inserted into the nozzle body 2. The nozzle body 2 is threaded on screwed on the feed pipe 3. In the swirl body r there is a helical thread Groove ¢ screwed in, the profile of which can be seen in Fig. 3. The nozzle body 2 and the swirl body t end together in a flat surface that is perpendicular to the nozzle axis lies. Due to the special outlet of the helical groove achieved in this way, a fan-shaped exit of the finely atomized broth is achieved.

Der besondere Vorteil dieser Düse liegt außerdem darin, daß sie schon mit geringen Drücken (r bis 3 atü) einwandfrei arbeitet, fertigungstechnisch keinerlei Schwierigkeiten bereitet und billig herzustellen ist.The particular advantage of this nozzle is that it already works flawlessly at low pressures (r to 3 atü), none in terms of production Difficult and cheap to manufacture.
