Description

Die bekannten Pulververstäuber stellen Behälter dar, aus denen in mehr oder minder primitiver Weise die pulverförmigen Stoffe herausgedrückt oder gesaugt werden. Eine feinere gleichmäßige Verstäuhung ist nur bei Apparaten ähnlich den Farbspritzgeräten unter Anwendung verhältnismäßig hochgespannter Luft o. dgl. möglich. Zum kontinuierlichen Gebrauch an Verarbeitungsmaschinen und zur Verwendung im Pflanzenschutz sind sie ungeeignet und unrationell.The known powder atomizers represent containers from which in more or less primitive way the powdery substances are pressed out or be sucked. A finer, even stifling is only similar in apparatus the paint spraying devices using relatively high-pressure air o. the like. possible. For continuous use on processing machines and for use in crop protection they are unsuitable and inefficient.

Zweck der Erfindung ist es, mit niedriggespannten Gasen, etwa Luft, pulverförmige Stoffe, äußerst fein verteilt in das zur Anwendung kommende Gas, weitgehend regelbar zu verstäuben, ohne daß Störungen durch Verlagerung oder Hängenbleiben des Behälterinhalts entstehen.The purpose of the invention is to use low-pressure gases, such as air, powdery substances, extremely finely distributed in the gas used, largely Can be regulated with dust without disruptions due to displacement or getting stuck of the container contents arise.

Ausführungsbeispiel Die bei a eintretende niedriggespannte Luft strömt zum größten Teil durch die Düse b aus und erzeugt hinter derselben im Verein mit der Ringdüse c ein Vakuum, das sich an der Düse d auswirkt. Der kleinere Teil der bei a eingeführten Luft gelangt durch den Kanal e und tritt aus den tangential zum trichterförmigen Raum f unter dem Sieb g angeordneten Düsen h, spiralenförmig an der Wand des Raumes f nach oben steigend, Luftstrahlen bildend aus. Diese Luftstrahlen werden durch den breiten, das Sieb g haltenden Sprengring i fast rechtwinklig nach der Mitte zu abgelenkt. Sie lockern einen Teil aus dem dem Sieb g aufliegenden pulverförmigen Stoff, der mit den Luftstrahlen zusammen durch die Düse d abgesaugt wird und durch die Ringdüse c in den Hauptluftstrom des Injektors gelangt, der das Pulver äußerst fein in Luft verteilt ausstößt. Durch Drosseln oder Verstärken des durch e abgezweigten Luftstroms ist eine sehr genaue Regelung der Verstäuber-Leistung im Rahmen der Injektorleistung zu erzielen.Embodiment The low-tension air entering at a flows for the most part through the nozzle b and generated behind the same in association with the ring nozzle c creates a vacuum, which affects the nozzle d. The smaller part of the Air introduced at a passes through channel e and exits the tangential to funnel-shaped space f under the sieve g arranged nozzles h, in a spiral the wall of the room f rising upwards, forming air jets. These air jets are almost at right angles due to the wide snap ring i holding the sieve g the center too distracted. They loosen part of the powdery material lying on the sieve g Substance that is sucked off together with the air jets through the nozzle d and through the ring nozzle c enters the main air flow of the injector, which extremely the powder finely dispersed in air. By throttling or strengthening the branched off by e Air flow is a very precise regulation of the atomizer performance in the context of the injector performance to achieve.
