Description
Düse zum Auflockern, Vernebeln oder Vermischen von pulverförmigen, breiigen, flüssigen oder gasförmigen Medien Die bisher bekannten Düsen zum Auflockern, Vernebeln oder Vermischen von pulverförmigen, breiigen, flüssigen oder gasförmigen Medien basieren auf der Grundlage, daß eine Zerstäubung unter Verwendung von Druckgas vorwiegend durch ein-oder mehrdrallige Richtkörper mit gleich- oder gegenläufiger Drallrichtung erzielt wird, wobei der Zerreißraum innerhalb des Düsenkörpers oder in einer oder mehreren Ebenen außerhalb des Düsenkörpers liegt. Der Gegenstand der vorliegenden Erfindung betrifft demgegenüber ein- oder tnehrdrallige oder-auch drallose Doppel- oder Mehrfachdüsen, bei denen ein Medium oder mehrere zu verarbeitende Medien außerhalb des Düsenkörpers durch die besondere Form und Anordnung :der Düseneinzelteile in bisher nicht erreichtem Ausmaße aufgelockert werden. Dabei werden die bisher bekannten Düsenleistungen bei einem Vergleich um ein Vielfaches überboten. In der Zeichnung ist eine gemäß der Erfindung ausgebildete Düse mit unter Gegendrallwirkung austretenden Strahlen beispielsweise dargestellt.Nozzle for loosening, atomizing or mixing powdery, pulpy, liquid or gaseous media The previously known nozzles for loosening, Fogging or mixing of powdery, pulpy, liquid or gaseous Media are based on atomization using pressurized gas predominantly by single or multi-twist straightening bodies with co-rotating or counter-rotating Twist direction is achieved, the tear space within the nozzle body or lies in one or more planes outside the nozzle body. The subject of In contrast, the present invention relates to single or multi-twisted or also twistless Double or multiple nozzles in which one or more media to be processed outside of the nozzle body due to the special shape and arrangement: the individual nozzle parts loosened up to a previously unattained extent. So far Known nozzle performance in a comparison many times over. In the The drawing is a nozzle designed according to the invention with a counter-swirl effect exiting rays shown for example.
Abb. i stellt einen schematischen Schnitt durch eine erfindungsgemäß ausgebildete Düse dar. In Abb.2 ist das Zusammentreffen der Medien- und Druckgasstrahlen außerhalb des Düsenkörpers dargestellt.Fig. I shows a schematic section through an inventive formed nozzle. In Fig.2 is the meeting of the media and compressed gas jets shown outside the nozzle body.
Gemäß Abb. i erfolgt der Zutritt des Druck-' gases i von außen zum Druckbehälter 3. Über die Seitenbohrungen q. im Anschlußstück 5 erreicht das Druckgas i über die linksspiraligen Windungen auf der Außenwandung des Hohlzylinders 8 die äußere Düsenöffnung C. Gleichzeitig wird über den Druckbehälter 3 auch dem zu behandelnden Medium :2 die erforderliche Beschleunigung vermittelt, und zwar dergestalt, daß dasselbe über die axiale Bohrung 7 im Anschlußstück 5 den rechtsspiraligen Windungen des Einsatzstückes 9 zugeführt wird und entlaii - der Außenwandung des in seinem oberen Teil konisch ausgebildeten Einsatzstückes 9 die innere Düsenöffnung B erreicht. Der Gummidichtring 6 verhindert infolge seiner hohen Elastizität jegliches Entweichen des Druckgases nach außen.According to Fig. I, the pressurized gas i enters the pressure vessel 3 from the outside via the side bores q. In the connection piece 5, the compressed gas i reaches the outer nozzle opening C via the left-hand spiral turns on the outer wall of the hollow cylinder 8 7 in the connection piece 5 is fed to the right-hand spiral turns of the insert piece 9 and along with the outer wall of the insert piece 9, which is conical in its upper part, reaches the inner nozzle opening B. The rubber sealing ring 6 prevents any escape of the compressed gas to the outside due to its high elasticity.
Zur .einfacheren Veranschaulichung wird in der folgenden Beschreibung aus den in Wirklichkeit in I',orm einer Kurve verlaufenden Strahlen je -eine theoretische Linie bzw. ein theoretischer Punkt zugrunde gelegt..Einfacheren for illustrating a curve extending beams depending -a theoretical curve or a theoretical point is taken as a basis in the following description, from the actually in I, orm '.
Die erfindungsgemäß erzielte Wirkung der Düse ist .darauf zurückzuführen, das ein gerader oder drallgerichteter Medienstrahl A (Abb.2), der nach der bekannten Auflockerung aus der inneren Düsenöffnung B austritt, auf den über die äußere Düsenöftiiung C austretenden gerade oder tangential, gleich- oder gegenläufig zum Medienstrahl gerichteten Druckgasstrahl auftrifft und ungehemmt durch bestimmte Räume oder Begrenzungen außerhalb des Düsenkörpers geführt wird, so das auf diese Weise eine weitere Auflockerung durch mehrnialiges Aufeinanderprallen der einzelnen Strahlen der verschiedenen Medien bis zu schwebendem Nebel erreicht wird.The effect of the nozzle achieved according to the invention is due to that is a straight or twisted media jet A (Fig. 2), which is based on the known Loosening exits from the inner nozzle opening B, onto the via the outer nozzle opening C Exiting straight or tangential, parallel or opposite to the media jet directed jet of pressurized gas and uninhibited by certain rooms or boundaries is performed outside of the nozzle body, so that in this way a further loosening through multiple collisions of the individual rays of the various media until it reaches floating fog.
Diese weitere Auflockerung wird dadurch erreicht, das die aus .den Düsenöffnungen B austretenden Medienstrahlen zunächst im Punkt G aufeinandertreffen. Anschließend werden die Medienstrahlen bei E von den Druckgasstrahlen erfaßt und zum Teil bis zum Punkt E getragen, in welchem die aus den Düsenöffnungen C austretenden Druckgasstrahlen zusammentreffen. Die hierdurch bereits in feinste Partikeln zerlegten Medien erfahren im Punkt F eine nochmalige weitere Auflocker ung bzw. Vermischung.This further loosening is achieved by the .den Media jets emerging from nozzle openings B initially meet at point G. The media jets are then detected by the pressurized gas jets at E and partly carried up to point E, in which the emerges from the nozzle openings C. Pressurized gas jets meet. Which have already been broken down into the finest particles as a result In point F, the media experience another further loosening or mixing.
Die Größe des jeweiligen Düsenöffnungs- oder Strahlenschnittwinkels u und die Größe der Düsenöffnungen C und B selbst richten sich nach den zu verarbeitenden Stoffen und dem geforderten Auflockerungsgrad sowie der gewünschten Ausbringungsmenge. Der Gummidichtüngsring6 (Abb. i) gestattet eine Veränderung der äußeren Düsenöffnung C (Abb. 2) durch einfaches Lockern oder Anziehen der Zerstäuberhaube fo (Abb:. i) auf dem Anschlußstüclc 5 (Abb. i). Durch die Änordnungen der Düseneinzelteile gemäß den vorstehenden Ausführungen wird die angestrebte Wirkung erzielt.The size of the respective nozzle opening or jet intersection angle u and the size of the nozzle openings C and B themselves depend on the ones to be processed Substances and the required degree of loosening as well as the desired application rate. The rubber sealing ring6 (Fig. I) allows the outer nozzle opening to be changed C (Fig. 2) by simply loosening or tightening the atomizer hood fo (Fig :. i) on the connection piece 5 (Fig. i). By arranging the individual nozzle parts according to the foregoing will achieve the desired effect.
Von besonderer Bedeutung sind der besonders geringe Verbrauch und der sehr niedrige Druck des Treibmittels, welche ihre Ursache in der regelbaren Einstellung der Strahlenwinkel und damit des Zerreißzentrums haben, wobei selbstverständlich die Wirtschaftlichkeit auch von der Gesamtanordnung und den Abmessungen der gegeneinander zweckmäßig abzustimmenden Einzelteile begründet liegt.The particularly low consumption and are of particular importance the very low pressure of the propellant, which is caused by the controllable Adjustment of the beam angle and thus the tear center have, of course the economy also from the overall arrangement and the dimensions of each other appropriately coordinated individual parts is justified.
