Handpumpenzerstäuber für korrosive Flüssigkeiten Hand pump sprayer for corrosive liquids

Aus Kunststoff gefertigte Handpumpenzerstauber, insbesondere wenn sie längere Zeit halten sollen, sind heute meist mit funktioneilen Metallteilen (etwa Federn und Kugeln) aus Edelstahl ausgerüstet. Brauchbar für derartige Spezialteile sind z.B. die Edelstahle Nr. 1.4301 oder 1.4401. Dadurch sind sie für viele Anwendungsgebiete auch ohne weiteres geeignet. Probleme ergeben sich allerdings dann, wenn mit Medien gearbeitet wird, die auch auf Edelstahl korrosiv wirken; z.B. salzsaure Entkalkungsmittel oder chemische Entrußungsmittel auf der Basis von Metallsalzen. Hier sind Zerstäuber der üblichen Art nicht mehr geeignet, da sie bereits nach kurzer Zeit infolge der Korrosion von Federn und Metallkugeln funktionsuntüchtig werden.Hand pump dispensers made of plastic, in particular if they are to last for a long time, nowadays they are usually made with functional metal parts (such as springs and Balls) made of stainless steel. Stainless steel No. 1.4301, for example, can be used for such special parts or 1.4401. This makes them suitable for many areas of application without further ado. Problems arise however, when working with media that also have a corrosive effect on stainless steel; e.g. hydrochloric acid Descaling agents or chemical sooting agents based on metal salts. Here are the atomizers The usual type is no longer suitable, as it takes a short time as a result of the corrosion of springs and metal balls become inoperable.

Es wurde nun gefunden, daß es durchaus möglich ist, die üblichen Handpumpenzerstäuber auch gegenüber den obenbezeichneten Medien korrosionsfest zu machen; hierzu müssen allerdings bei Federn und Kugeln verschiedene Methoden benutzt werden. Während es bei den Stahlfedern genügt, diese lückenlos mit einem porenfreien Kunststoffüberzug, beispielsweise Rilsan^ (aus höheren Aminofettsäuren hergestellte thermoplastische Polyamide, s. Römpp's Chemielexikon 7· Auflage Band 5, Seite 2989) zu versehen, hat es sich als notwendig herausgestellt, die Ventil-Kugeln aus langfristig korrosionsfestem Metall bzw. Metallegierung (z.B. Titan) zu fertigen, da einfaches überziehen, auch mit Edelmetallen wie z.B. Gold) sich als nicht ausreichend erwiesen hat.It has now been found that it is quite possible to use the usual hand pump sprayer compared to the to make the media mentioned above corrosion-resistant; for this, however, different springs and balls have to be used Methods are used. While it is sufficient with the steel springs to completely cover them with a pore-free plastic coating, for example Rilsan ^ (from higher amino fatty acids Manufactured thermoplastic polyamides, see Römpp's Chemielexikon 7 edition volume 5, page 2989) To provide, it has been found necessary to make the valve balls from long-term corrosion-resistant To manufacture metal or metal alloy (e.g. titanium), as it is easy to coat, also with precious metals such as Gold) has proven to be insufficient.

Durch Einbau derart hergestellter Spezialteile in einen ansonsten den Anforderungen entsprechenden Handpumpenzerstäuber üblicher Bauart (wobei die Spezialteile natürlich in ihren Abmessungen den vorgegebenen Dimensionen des sie aufnehmenden Geräts entsprechen müssen) gelingtBy installing special parts produced in this way in a hand pump sprayer that otherwise meets the requirements usual design (with the special parts of course in their dimensions the given dimensions of the device receiving them) succeeds

es, einen lange Zeit funktionstüchtigen Sprüher auch für korrosive Flüssigkeiten zu erhalten.it is necessary to obtain a long-term functional sprayer, even for corrosive liquids.

Im folgenden wird anhand der nachstehenden Zeichung ein Handpumpenzerstäuber beschrieben, der mit korrosionsfesten bzw. -festgemachten Metallteilen für das Versprühen von korrosiven Flüssigkeiten ausgerüstet ist.In the following, a hand pump atomizer is described with reference to the following drawing, which with Corrosion-resistant or hardened metal parts for spraying corrosive liquids is.

I bedeutet ein Steigrohr, 2 ein dieses Steigrohr nach unten abdichtendes Sieb, 3 die Ventilkammer, 4 den Boden der Ventilkammer mit der Ventilöffnung oberhalb des Steigrohrs 1, 5 eine aus Titan gefertigte Kugel, die so dimensioniert ist, daß sie die Ventilöffnung verschließen kann, 6 die Kugel nach oben begrenzende Nocken, 7 den Pumpzylinder, 8 eine (zum Pumpzylinder 7 führende) öffnung, 9 eine mit Rilsan*1- überzogene, in dem Pumpenzylinder liegende Metallfeder beispielsweise aus Edelstahl, 10 den Pumpkolben mit Gummimanschette,I means a riser pipe, 2 a sieve that seals this riser pipe downwards, 3 the valve chamber, 4 the bottom of the valve chamber with the valve opening above the riser pipe 1, 5 a ball made of titanium which is dimensioned so that it can close the valve opening, 6 cams delimiting the ball at the top, 7 the pump cylinder, 8 an opening (leading to the pump cylinder 7), 9 a Rilsan * 1 -coated metal spring located in the pump cylinder, for example made of stainless steel, 10 the pump piston with a rubber sleeve,

II einen die Pumpzylinder 7 mit dem Düsenstock 12 verbindenden Gang, 13 ein im Düsenstock 12 befindliches Auslaßventil, das mit einer zweiten Titankugel 14 ausgerüstet ist, 15 bedeutet den aufgeschraubten Düsenkopf mit innenliegender Düse 16, und 17 den Pumphebel.II a connecting the pump cylinder 7 to the nozzle assembly 12 1st passage, 13 an outlet valve located in the nozzle assembly 12, which is equipped with a second titanium ball 14 is, 15 means the screwed-on nozzle head with internal nozzle 16, and 17 the pump lever.

Der Zerstäuber funktioniert so, daß die Kugel 5 im Ruhezustand das Steigrohr 1 abdichtet, bei Betätigung des Pumpmechanismus aber hochgesaugt wird und den Flüssig keitsweg (vom Steigrohr über die öffnung 8 in den Pumpzylinder 7 und von dort über den Gang 11 zur Düse 16) freigibt. Die zweite Kugel wirkt als Rückschlagventil, das das Ansaugen von Luft beim erstrebten Ansaugen von Flüssigkeit aus dem Vorratsbehälter verhindern muß.The atomizer works in such a way that the ball 5 seals the riser pipe 1 when it is actuated of the pump mechanism is sucked up and the liquid keitsweg (from the riser pipe via the opening 8 into the pump cylinder 7 and from there via the passage 11 to the nozzle 16). The second ball acts as a check valve, which must prevent the aspiration of air when aspirating liquid from the reservoir.
