Abstract

Eine Modulare Winkeldüse, bei der der Sprühstrahl seitlich aus einen Druckrohr austritt, ist zerlegbar um den Düsenkörper auswechseln und im demontierten Zustand reinigen zu können. Dieser wird mittels einer Spannschraube an Ende des Druckrohres über einem Spannkeil im Druckrohr positioniert und abgedichtet.A modular angle nozzle, in which the spray jet emerges laterally from a pressure pipe, can be dismantled to replace the nozzle body and to be able to clean it in the disassembled state. This is positioned by means of a clamping screw at the end of the pressure tube over a clamping wedge in the pressure tube and sealed.

Description

Winkeldüsen für flüssige Medien werden in der Chemie- und Lebensmittel-Industrie, aber auch in der Motoren- und Fahrzeugtechnik eingesetzt.Angle nozzles for liquid media are used in the chemical and food industry, but also in engine and vehicle technology.

Dabei ergibt sich aber vielfach das Problem, dass die Düsen durch die asymmetrischen und vielfach turbulenten Strömungsherhältnisse am Auslass relativ schnell verschleißen und sich leicht zusetzen.However, this often results in the problem that the nozzles wear relatively quickly due to the asymmetric and often turbulent flow conditions at the outlet and easily clogged.

Dies ist bei kurzem Schaft der Düse weniger problematisch, weil der Auslass vom Düsenrohr her zugängig und ggf. zu reinigen ist. Je länger jedoch der Schaft, um so weniger ist dies möglich. Dagegen ist eine Reinigung durch den oft hyperfeinen Auslasskanal in der Regel unmöglich, vielfach führt dies eher zur Zerstörung der Auslass-Geometrie, abgesehen davon, dass eine Reinigung dort kaum dauerhaft ist, weil Ablagerungen nur zur Seite geschoben, aber nicht beseitigt werden – und dies gilt auch für Reinigungsversuche mit Druckluft oder hydraulischen Medien.This is less problematic with short shaft of the nozzle, because the outlet is accessible from the nozzle tube and if necessary to clean. However, the longer the stem, the less possible. In contrast, a cleaning by the often hyperfine outlet channel is usually impossible, often this leads rather to the destruction of the outlet geometry, apart from the fact that a cleaning is hardly permanent there, because deposits pushed only to the side, but not eliminated - and this also applies to cleaning tests with compressed air or hydraulic media.

Daher ist es verbreitet, Einspritzdüsen etc. bei Defekt stets auszuwechseln und zu entsorgen, was angesichts ihrer Kosten eigentlich untragbar erscheint.Therefore, it is common to replace injectors, etc. in case of defect always and dispose of what, considering their cost actually unsustainable.

Aufgabe vorliegender Erfindung ist es daher, dieses Problem zu lösen und einen Düsentyp zu schaffen, der leicht zu reinigen, oder bei dem nur Kleinteile zu ersetzen sind.Object of the present invention is therefore to solve this problem and to provide a nozzle type that is easy to clean, or in which only small parts are to be replaced.

Dies wird erfindungsgemäß dadurch erreicht, dass die Düse modular aufgebaut und auch bei langen Schaft zerlegbar ist, so dass der eigentliche Düsenkörper zugänglich wird, um gereinigt werden zu können, oder dass nur ein Kleinteil – z. B. das Düsenelement selbst – ausgewechselt werden muss. Ein zusätzlicher Vorteil ergibt sich dabei dadurch, dass der Düsenkörper auswechselbar ist und so durch verschiedene Einsätze mit unterschiedlicher Geometrie nach Bedarf unterschiedliche Sprühbilder erzielbar sind.This is inventively achieved in that the nozzle is modular and can be dismantled even with a long shaft, so that the actual nozzle body is accessible to be cleaned, or that only a small part -. B. the nozzle element itself - must be replaced. An additional advantage results from the fact that the nozzle body is replaceable and thus different spray patterns can be achieved by different inserts with different geometry as needed.

Eine erfindungsgemäße Ausführung umfasst daher das Druckrohr (also den Schaft), der im oberen Bereich mit einem Gewinde, Flansch oder anderen Befestigungsmitteln mit der Medien-Zuführung verbunden ist. Der untere Teil dieses Druckrohrs enthält eine Aussparung auf der Oberseite, in die der Düsenauslass so positioniert ist, dass der austretende Strahl ungehindert durch die benannte Öffnung erfolgen kann.An embodiment according to the invention therefore comprises the pressure tube (ie the shaft), which is connected in the upper region with a thread, flange or other fastening means with the media supply. The lower part of this pressure tube contains a recess on the upper side into which the nozzle outlet is positioned so that the outgoing jet can pass unhindered through the named opening.

In das Druckrohr ist ist ein Spannkeil eingeschoben, der auch als Düsenträger fungiert. Sein Querschnitt ist ein nahezu hälftig abgeschnittenes Kreissegment, dessen gerundete Aussenkontur – bis auf eine Montagetoleranz – dem Innenquerschnitt des Duckrohrs entspricht.In the pressure tube is a clamping wedge inserted, which also acts as a nozzle carrier. Its cross-section is a circle segment cut almost halfway, whose rounded outer contour - with the exception of a mounting tolerance - corresponds to the inner cross-section of the duck tube.

Die Abschnittslinie entspricht der Mitte der abgeflachten Oberfläche des Spannkeils. Diese Oberfläche verläuft um 2° angefast zur Längsachse.The section line corresponds to the center of the flattened surface of the clamping wedge. This surface is 2 ° chamfered to the longitudinal axis.

Auf der Oberfläche des Spannkeils ist die flache Unterseite des Düsenkörpers verschiebbar angeordnet. Durch verringerte Breite des Spnnkeils und die dadurch entstehenden seitlichen Durchtritte, wird die Zuführung der Medien zum Zentrum des Düsenkörpers bewirkt. Der Düsenkörper weist zwei gegenüberliegende, feine Kanäle auf, die nahezu tangential in die Düsenbohrung eingeführt sind und die Medienzuführung von den seitlichen Zwischenräumen zwischen Spannkeilund Druckrohr in die Düse bewirken.On the surface of the clamping wedge, the flat bottom of the nozzle body is slidably disposed. Due to reduced width of the Spnnkeils and the resulting lateral passages, the supply of the media is effected to the center of the nozzle body. The nozzle body has two opposite, fine channels, which are introduced almost tangentially into the nozzle bore and cause the media supply from the lateral gaps between clamping wedge and pressure tube in the nozzle.

Die Öffnung des Druckrohrs ist mit einer Spannschraube verschlossen, die in einem Innengewinde des Schaftes befestigt ist. Sie drückt den Spannkeil so in das Druckrohr, dass die gerundere Oberseite des Düsenkörpers gegen die Innenwandung des Druckrohres verspannt ist.The opening of the pressure tube is closed with a clamping screw, which is fixed in an internal thread of the shaft. It presses the clamping wedge into the pressure tube so that the rounder top side of the nozzle body is clamped against the inner wall of the pressure tube.

Durch die Keilwirkung wird der Düsenkörper bei der Montage gegen die Rohrinnenwand gepresst und dichtet schon bei relativ geringen Axialkräften sicher gegen den Systemdruck ab. Die Keilwirkung bewirkt dabei auch einen Ausgleich von Fertigungstoleranzen der Elemente.Due to the wedge effect, the nozzle body is pressed against the pipe inner wall during assembly and reliably seals against the system pressure even at relatively low axial forces. The wedge effect also causes a compensation of manufacturing tolerances of the elements.

Durch Abschrauben der Spannschraube wird der Spannkeil und die darauf sitzende Düse zugänglich, die dann leicht zu reinigen oder zu ersetzen ist.By unscrewing the clamping screw, the clamping wedge and the seated nozzle are accessible, which is then easy to clean or replace.

The media supply takes place 1 into the pressure tube 2 in the amount of a recess 3 the nozzle body 4 contains. He is from a clamping wedge 5 held as a nozzle carrier, by the clamping screw 6 , which also causes the closure of the tube is pressed.
