Abstract
Description
SPRITZDUESE ZUM ZERSTAEUBEN VON FLUESSIGKEITEN, HAUPTSAECHLICH FARBEN UND LACKE, IN FORM EINES FLACHSTRAHLES Die Neuentwicklung betrifft eine Spritzdüse zum Zerstäuben von Fluessigkeiten, in Form eines Flachstrahles. Die Flüssigkeit, z.B. Farbe, wird mittels einer elektr. oder und mech. Kolben-, Membran-, RKM- oder sonst einer Pumpe als Förderaggregat ausgestatteten Spritzpistole unter hohem Druck durch die Düse gefördert. Bei den herkömmlichen Flachstrahldüsen, für solche luftlos zerstäubenden Spritzpistolen, muss die Austrittsöffnung im Düsenkopf sehr schmal sein, da die Zerstäubung nur durch den, vom Förderaggregat erzeugten Druck erfolgt. Dadurch, dass die Düsenöffnung extrem schmal sein muss, ist die Düse sehr oft durch kleine Unreinheiten, die sich in jeder Farbe befinden können, verstopft. Dies führt laufend zu längeren Arbeitsunterbrüchen.SPRAY NOZZLE FOR SPRAYING LIQUIDS, MAINLY COLORS AND PAINT, IN THE FORM OF A FLAT JET The new development concerns a spray nozzle for atomizing liquids, in the form of a flat jet. The liquid, e.g. color, is achieved by means of an electr. or and mech. Piston, diaphragm, RKM or otherwise a pump equipped as a delivery unit spray gun under high pressure conveyed through the nozzle. With conventional flat jet nozzles, airless for those atomizing spray guns, the outlet opening in the nozzle head must be very narrow because the atomization takes place only through the pressure generated by the delivery unit. Because the nozzle opening has to be extremely narrow, the nozzle is very often through clogs small impurities that can be in any color. this leads to continuously to longer work interruptions.
Um diese Verstopfung zu vermeiden, hat man in die Düsenhalterung Filter eingebaut. Der Nachteil dieser eingebauten Filter ist eine sehr aufwendige Konstruktion der Flachstrahldüse samt des Förderaggregates, wenn der Filtereffekt wirkungsvoll sein soll. Ein weiterer Nachteil solcher Einbaufilter ist die unbedingte Feinmaschigkeit. Dies bedeutet aber, dass solch fein- und feinstmaschigen Filter schon nach einer spezifisch kurzen Betriebszeit mit Farbe oder Spritzgut verklebt sind, d.h. der Durchfluss ist unterbrochen.To avoid this clogging, there is a filter in the nozzle holder built-in. The disadvantage of this built-in filter is a very complex construction the flat jet nozzle including the conveyor unit, if the filter effect is effective should be. Another disadvantage of such built-in filters is the absolute fine mesh. This means, however, that such fine-meshed and finely-meshed filters after just one are stuck to paint or spray material for a specific short operating time, i.e. the Flow is interrupted.
Aufgabe dieser Neuentwicklung ist es, eine Flachstrahldüse ohne die eingangs präzisierten Nachteile zu entwickeln. Als zusätzliches Merkmal wird verlangt, dass dieses Düsenaggregat gegenüber dem Förderaggregat um dessen z- Achse drehbar ist.The task of this new development is to create a flat jet nozzle without the to develop disadvantages specified at the beginning. An additional feature is required that this nozzle unit can be rotated about its z-axis with respect to the delivery unit is.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass gemäss F i g. 1 an einem Förderaggregat 14 mit einer Flügelüberwurfmutter 13 das gesamte drehbare Flachstrahl-Düsenaggregat, bestehend aus den Einzelbauelementen 1, + 13, angeordnet ist. Die Funktion dieser Einzelbauelemente von 13 + 1 ist folgende.This object is achieved according to the invention in that, according to F i g. 1 on a conveyor unit 14 with a wing nut 13 the entire rotatable flat jet nozzle unit, consisting of the individual components 1, + 13, is arranged. The function of these individual components of 13 + 1 is as follows.
Bauelement 12 ist ein Flanschrohr mit einem Innensechskant gemäss F i g. 4, dessen Flansch von der Ueberwurfmutter 13 gas- und flüssigkeitsdicht an das Förderaggregat 14 drehfest angepasst wird.Component 12 is a flange tube with a hexagon socket according to FIG F i g. 4, the flange of which from the union nut 13 is gas- and liquid-tight the delivery unit 14 is adapted to be rotationally fixed.
Flanschrohr 12 ist mit der Sechskant-Ueberwurfmutter 11 so verschraubt, dass alle nachfolgenden Bauelemente 10 + 1?gebremst - drehbar' um die z - Achse nachgeordnet sind.The flange tube 12 is screwed to the hexagon union nut 11 in such a way that that all subsequent components 10 + 1 "braked - rotatable" around the z - axis are subordinate.
Dieses Merkmal der gebremsten Drehbarkeit um die z-Achse wird dadurch erzwungen, dass das Rohrstück 7, kraftschlüssig in eine Zwischenüberwurfmutter mit Handriffelung 6 ca. auf seiner halben Länge eingepresst ist.This feature of the braked rotatability about the z-axis is thereby forced that the pipe section 7, non-positively in an intermediate union nut with Hand corrugation 6 is pressed in about half its length.
Auf dem herausragenden Teil 7a sitzt die Sechskant-Ueberwurfmutter 11 und in deren Innenhohlraum der längselastische Dichtring 8, gegen die ein Rohrstück 9 drückt, welches durch den Seegerring 10 formschlüssig am Rohrende 7a gehalten wird.The hexagonal union nut sits on the protruding part 7a 11 and in the inner cavity of the longitudinally elastic sealing ring 8, against which a pipe section 9 presses, which is held positively by the Seeger ring 10 on the pipe end 7a will.
Durch diese konstruktive Lösung ist der nachfolgende Düsenstock mit den Bauelementen 10 + 1 gebremst drehbar um die z - Achse gegenüber 14 angebaut.This constructive solution means that the following nozzle assembly is also included the components 10 + 1 braked rotatably around the z - axis opposite 14 grown.
Die eigentliche Erfindungsaufgabe wird durch ein Zusammenwirken der Dralldüse 4, siehe Fig. 1 + 3 mit der Schlitzdüse 1 siehe Fig. 1 + 2 erreicht.The actual task of the invention is achieved through the interaction of the Swirl nozzle 4, see Fig. 1 + 3 achieved with the slot nozzle 1 see Fig. 1 + 2.
Die Dralldüse 4 gemäss Fig. 3 hat an ihrer Vorderseite tangentialeingefräste Schlitze 4c. Strömt die Spritzflüssigkeit in der Bohrung 4a Figl. 1 und den Löchern 4b zu den Tangentialschlitzen 4c, so entsteht im kegeligen Hohlraum la der Hauptdüse 1 ein Drehkegel des Sprühgutes, also der Farbe und wird gegen die Kegelspitze gedrückt, kann hier durch eine Längsöffnung lb gemäss Fig. 1 + 2 in feinstversprühten Teilchen ausströmen. Um einen ebenen Flachstrahl zu erzwingen, muss diese Schlitzöffnung lb gemäss Fig. 2 zu x-y-Ebene entgegen der Drallrichtung der tangentialen Schlitze 4c der Innendüse 4 etwas verdreht im Düsenhalter 2 eingesetzt sein.The swirl nozzle 4 according to FIG. 3 has milled tangentially on its front side Slots 4c. The spray liquid flows in the bore 4a Figl. 1 and the holes 4b to the tangential slots 4c, the main nozzle is created in the conical cavity la 1 a rotating cone of the spray material, i.e. the color, and is pressed against the tip of the cone, can here through a longitudinal opening lb according to Fig. 1 + 2 in very finely sprayed particles emanate. In order to force a flat flat jet, this slot opening must be 1b according to FIG. 2 to the x-y plane against the twist direction of the tangential slots 4c of the inner nozzle 4 can be inserted in the nozzle holder 2 in a slightly rotated manner.
Da alle Durchflussbohrungen und Schlitze im gesamten Düsenstock d.s. die Bauelemente 1 - 10 spezifisch gross sind, gibt es kein Verstopfen während des Betriebes, sondern ein selbsttätiges ständiges Reinigen und Durchblasen.Since all flow bores and slots in the entire nozzle holder d.s. the components 1 - 10 are specifically large, there is no clogging during the Operation, but an automatic one constant cleaning and blowing.
Diese Spritzdüse ist nie verstopft und stets betriebsbereit. This spray nozzle is never clogged and always ready for use.
Ebenso erfolgt das Reinigen durch blosses Durchspülen mit einem Lösungsmittel. Cleaning is also carried out by simply rinsing it with a solvent.
Der gesamte Düsenstock (1-10) ist drucklos gebremst in jede Drehrichtung verdrehbar. Ist die Spritzpistole unter dem Druck des Sprühmediums, wird der Düsenstock mit den Bauelementen 8 und 9 gegen den vorderen Flansch der Sechskant-Haltemutter 11 gepresst und verhindert ein Verdrehen des gesamten Düsenstockes in der x-y-Ebene um die z-Achse. The entire nozzle assembly (1-10) is braked without pressure in any direction of rotation rotatable. If the spray gun is under the pressure of the spray medium, the nozzle holder becomes with components 8 and 9 against the front flange of the hexagonal retaining nut 11 and prevents twisting of the entire nozzle assembly in the x-y plane around the z-axis.
