Description

Umlaufender Spritzkopf für Farbspritzanlagen Die Erfindung bezieht sich auf einen umlaufenden Spritzkopf für Farbspritzanlagen. Die bei den bisher bekannten Einrichtungen ähnlicher Art auftretenden Nachteile konstruktiver und betrieblicher Natur werden durch die vorliegende Erfindung vermieden, indem i. eine Verschmutzung laufender Teile durch das Spritzmittel infolge geeigneter Düsenanordnung nicht auftritt, 2. eine ,gute Spritzwirkung durch hohe Drehzahl des umlaufenden Teiles sowie flachen Spritzkegelivinkel erreicht wird, 3. .eine Störung des zerstäubten Spritzmittels durch ,die Antriebsabluft nicht eintritt und q.. durch einfachen Aufbau der Einrichtung schnelles Zerlegen, Reinigen und gegebenenfalls Reparieren rasch möglich ist. Die Zeichnung, welche schematisch und unmaßstäblich ist, zeigt den Erfindungsgegenstand in drei Abbildungen. Abb. i zeigt einen Längenschnitt, Abb. 2 einen Teilschnitt hierzu, in Richtung A gesehen, während Abb. 3 einen Schnitt B-C zu Abb. 2 darstellt.Revolving spray head for paint spraying systems The invention relates to on a rotating spray head for paint spraying systems. The ones so far known facilities of a similar type occurring disadvantages constructive and operational Nature are avoided by the present invention by i. a pollution moving parts through the spray agent does not occur due to a suitable nozzle arrangement, 2. A good spray effect due to the high speed of the rotating part and flat Spray cone angle is reached, 3.. A disruption of the atomized spray agent through, the exhaust air from the drive does not enter and q .. through the simple structure of the device quick dismantling, cleaning and, if necessary, repairing is possible. the Drawing, which is schematic and not to scale, shows the subject of the invention in three pictures. Fig. I shows a longitudinal section, Fig. 2 a partial section in this regard, seen in direction A, while Fig. 3 shows a section B-C to Fig. 2.

Das Spritzmittela (Farbe, Lack) wird durch die Zuführungsleitung bder Düse c zugeführt. Das Betriebsmittel d (Preßluft) tritt durch Bohrungene im Düsenkörper f .in den vom Läufer g und dem Düsenrohr lt gebildeten Ringkanal i ein und strömt zum Teil durch die Antriebsdüsen k gegen die Schaufeln 1 des fest im Mantel nz angebrachten Schaufelkörpers n, wobei die dabei auftretende Reaktionskraft den im Wälzlager o drehbar gelagerten Läuferu in rasche Drehung (2ooo bis 3000U/Min.) versetzt. Das zum Antrieb gebrauchte Betriebsmittel verläßt die erfindungsgemäße Einrichtung durch .die öffnungp im Mantel m. Der Hauptstrom des Betriebsmittels d verläßt den Ringkanal i an der Ringdüse g, dabei das Spritzmittela in bekannter Weise zerstäubend. Die Ablenkdüse r, welche ebenfalls vom Ringkanal i her mit Betriebsmittel versorgt wird, sendet einen Betriebsmittelstrahl s normal (unter einem Winkel a von 9o°) zur Hauptströmungsrichtungi aus, welcher das zerstäubte Spritzmittelu ablenkt. Da die Ablenkdüse r mit dem Läufer g um die Hauptströmungsrichtung t kreist, bestreicht das zerstäubte Spritzmittel .u einen kegelförmigen Raum v vom Kegelwinkel Zur Vermeidung eines Anlauftotpunktes sind die Schaufeln I in ungerader Zahl vorgesehen (Abb.3).The spray agent a (paint, varnish) is fed through the feed line b to the nozzle c. The operating medium d (compressed air) enters the ring channel i formed by the rotor g and the nozzle pipe lt through bores in the nozzle body f The reaction force that occurs causes the rotor, which is rotatably mounted in the roller bearing, to rotate rapidly (2ooo to 3000rpm). The operating medium used for the drive leaves the device according to the invention through the opening p in the jacket m. The main flow of the operating medium d leaves the ring channel i at the ring nozzle g, atomizing the spray medium a in a known manner. The deflecting nozzle r, which is also supplied with operating fluid from the ring channel i, sends out an operating fluid jet s normal (at an angle a of 90 °) to the main flow direction i, which deflects the atomized spray fluid. Since the deflecting nozzle r with the rotor g circles around the main flow direction t, the atomized spray .u spreads a conical space v from the cone angle.

Beim Spritzen langer Hohlkörper ist es ohne weiteres möglich, die beschriebene Einrichtung auf einer geeigneten Verlängerung anzubringen.When injecting long hollow bodies, it is easily possible to use the to attach the device described on a suitable extension.
