Description

Rotierende tellerförmige Scheibe zum Zerstäuben von Flüssigkeiten Es ist bekannt Lösungen velrschiedener Art, z. B. Blut, Milch, Seifen- oder Salzlösungen, dadurch zu zerstäuben, daß sie auf eine sich schnell drehende Scheibe aufgebracht werden. Hierdurch wird die Flüssigkeit zerstäubt und schnell verdampft, sodaß die gelösten Stoffe in Pulverform erhalten werden.Rotating plate-shaped disc for atomizing liquids It is known solutions of various kinds, e.g. B. blood, milk, soap or salt solutions, to be atomized by applying it to a rapidly rotating disc will. As a result, the liquid is atomized and evaporated quickly, so that the dissolved substances can be obtained in powder form.

Zur Förderung der Verdampfung wird meistens ein warmer Gasstrom, z. B. erhitzte Luft, durch den Apparat geführt, in dem die sich schnell drehende Scheibe angeordriet ist.To promote evaporation, a warm gas stream, e.g. B. heated air, passed through the apparatus in which the rapidly rotating disc is ordered.

Die Scheiben haben die Form eines Tellers und können am Rande mit eingesetzten Röhren versehen sein die aus dem Rand herausragen und den Flüssigkeitsstrahl von der Scheibe hinwegleiten. The slices are in the shape of a plate and can be placed on the edge inserted tubes that protrude from the edge and the liquid jet lead away from the pane.

Infolge der größeren Geschwindigkeit am Ende der Röhren bekommt man ein feines Pulver. Die Röhren können dabei mit erweiterten Eintrittsöffnungen versehen sein.As a result of the greater speed at the end of the tubes you get a fine powder. The tubes can be provided with enlarged inlet openings be.

Ein Nachteil der bekannten Zerstäubungsscheibetn mit eingesetzten Röhren besteht darin, daß es vorkommt, daß ein geschlossener Strahl bis an die Wand des Apparates geschleudert wird; es tritt dann überhaupt keine Zerstäubung der Flüssigkeit ein. Die Flüssigkeit wird in diesem Fall nicht oder nur sehr mangelhaft verdampft, ,und es bildet sich kein Pulver. überdies ist die sich ergebende Krustenbildung an der Wand des Apparates sehr hinderlich. A disadvantage of the known atomizing disks used Tubing consists in the fact that it happens that a closed beam reaches the wall the apparatus is spun; there is then no atomization of the liquid at all a. In this case, the liquid is not or only very poorly evaporated, and powder does not form. moreover, the resulting crust formation is very cumbersome on the wall of the apparatus.

Die vorgenannten Nachteile werden durch die Erfindung beseitigt. Gemäß der Erfindung sind in den Wänden der eingesetzten Röhren Löcher angeordnet, die eine solche Lage besitzen, daß durch sie Luft odier ein anderes Gas in die Röhren ein- tritt, wenn die Scheibe in Betrieb ist; diese Löcher können über die@ ganze Länge der Röhre verteilt sein. Sie befinden sich vorzugsweise, in Strömungsrichtung gesehen, in dem hinter der Einschnü,rung liegenden Teil der Röhre parallel zur Drehachse oder senkrecht dazu in dem, in Drehrichtung gesehen, vorderen Wandteil. The above-mentioned disadvantages are eliminated by the invention. According to the invention, holes are arranged in the walls of the tubes used, which are in such a position that air or another gas enters the tubes through them a- occurs when the disc is in operation; these holes can be distributed over the entire length of the tube. You are preferably in Seen in the direction of flow, in the part of the tube behind the constriction parallel to the axis of rotation or perpendicular to it in the front one, seen in the direction of rotation Wall part.

Es wird durch diese Ausbildung erreicht, daß die mit großer Geschwindigkeit durch die Röhre fließende Flüssigkeit die Luft oder ein anderes Gas, das sich im Apparat befindet, mitsaugt und sich innig damit vermischt. Hierdurch wird die Geschwindigkeit des Strahls erkennbar herabgesetzt. It is achieved by this training that the with great speed Liquid flowing through the tube is the air or other gas that is in the Apparatus is located, sucks in and is intimately mixed with it. This will increase the speed of the beam is noticeably reduced.

Demzufolge reicht die Geschwindigkeit des Strahls nicht mehr aus, die Wand des Apparates zu erreichen. Außerdem wird durch die Vermischung mit dem Gas eine Weitgehende Verteilung des Strahls beim Austreten aus der Röhre erzeielt, wodurch das Pulver feiner und voluminöser wird.As a result, the speed of the jet is no longer sufficient to reach the wall of the apparatus. In addition, mixing with the Gas creates a large distribution of the jet when it exits the tube, making the powder finer and more voluminous.

Gemäß einer vorteilhaften Ausführungsform der Erfindung können die eingesetzten Röhren die Form einer Venturi-Röhre aufweisen, d. h. die Rohre verengt sich zunächst und erweitert sich darauf wieder. Es wird hierdurch die Vermischung der Flüssigkeit mit dem Gas verbessert und die Geschwindigkeit des Strahls stärker abgebremst. According to an advantageous embodiment of the invention, the inserted tubes have the shape of a venturi tube, d. H. the pipes narrowed at first and then expands again. This is how it gets mixed up the liquid with the gas improves and the speed of the jet stronger braked.

Es wurde weiter gefunden, daß die Flüssigkeit noch besser zerstäubt wird, wenn man das Röhrenende, aus dem die Flüssigkeit austritt, auf einer Seite verlängert und umbiegt, vorzugsweise derart, daß das umgebogene Ende stumpfwinklig zur Röhr'enachse verläuft. Hierdurch wird die Richtung des Strahls beim Austreten geändert und seine Geschwindigkeit von neuem herabgesetzt, wodurch eine noch bessere Verteilung der Flüssigkeit und eine innigere Vermischung der Flüssigkeit mit dein Gas herbeigeführt wird.It was further found that the liquid atomizes even better if the end of the tube, from which the liquid emerges, is on one side extended and bent over, preferably in such a way that the bent end is at an obtuse angle runs to the tube axis. This will determine the direction of the jet as it exits changed and reduced its speed again, making an even better one Distribution of the liquid and a more intimate mixing of the liquid with your Gas is brought about.

Bei der Vorrichtung gemäß der Erfindung wird ein Weiterschießen des geschlossenen Flüssigkeitsstrahls bis an die Wand des Apparates vollkommen verhindert und eine intensive Zerstäubung erzielt. In the device according to the invention, a further shooting of the closed liquid jet up to the wall of the device is completely prevented and an intensive atomization is achieved.

Es wird gleichzeitig die stark korrodierende Wirkung des Flüssigkeitsstrahls und eine Krustenbildung an der Wand des Apparates vermieden, wodurch der Apparat eine längere Lebensdauer erhält. Man kann mit der Zerstäubungsscheibe gemäß der Erfindung bereits bei einer geringeren UmLdrehunglsgeschwindilgkeit eine bessere Zerstäubug und ein feineres Pulver von niedrigerem Volumgewicht erhalten als mit den bekannten Scheiben', so daß unter geringerem Kraftaufwand bessere Ergebnisse erzielt werden können.At the same time, the highly corrosive effect of the liquid jet becomes and a crust formation on the wall of the apparatus is avoided, whereby the apparatus has a longer lifespan. One can use the atomizing disc according to the Invention a better one even at a lower speed of rotation Atomization and a finer powder of lower volumetric weight than obtained with the well-known discs', so that better results with less effort can be achieved.

Bei der dargestellten Ausführungsform liegt die D reh -achse in der Zeichnungsebene. Für den Fall, daß die Rohre I derart anlgeordnet sind, daß die Vorderkanten der Verlängerungen 4 beim Umlauf der Scheibe, in der Drehrichtung gesehen, vorlaufen, werden die Löcher 2 und 3 zweckmäßig senkrecht zu der dargestellten Lage angeordnet. In the illustrated embodiment, the tube I has the shape a venturi tube. With 2 and 3 holes in the wall of the tube are designated, through which the gas is sucked through.
