Description

DEKONTAMINATIONSFLÜSSIGKEITS-SPRÜHGERAT DECONTAMINATION LIQUID SPRÜHGERAT
Die Erfindung betrifft ein Dekontaminationsflüssigkeits-Sprühgerät zum Besprühen von mit schädlichen Substanzen kontaminieren Objekten mit Dekontaminationsflussigkeit, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a decontamination liquid spray device for spraying objects contaminated with harmful substances with decontamination liquid, according to the preamble of claim 1.
Bei der Dekontamination von Objekten, insbesondere im militärischen Bereich, die durch für den Menschen schädliche Substanzen, wie z.B. Giftgas, radioaktive Partikel oder biologische Kampfstoffe verunreinigt sind, ist es bekannt, diese mit einer z.B. unter derIn the decontamination of objects, especially in the military field, which are caused by substances harmful to humans, e.g. Poison gas, radioactive particles or biological warfare agents are contaminated, it is known to use a e.g. under the
Bezeichnung „ GD 5 -Lösung " von der Anmelderin vertriebenen Dekontaminationslösung zu neutralisieren.Neutralize the term "GD 5 solution" from the decontamination solution sold by the applicant.
Hierzu wird die Dekontaminationslösung beispielsweise mittels einer Sprühvorrichtung mit Hilfe eines nach dem Pulsationsverfahrens arbeitenden Geräts auf das zu dekontaminierende Objekt aufgesprüht, wie dies z.B. in der DE 41 04 134 C2 beschrieben ist. Die in der Schrift zum Auftrag der Dekontaminationslösung beschriebene Vorrichtung umfasst hierzu eine Brennkammer, in der ein Benzin-Luftgemisch gezündet wird, und die Tröpfchen der Dekontaminationslösung in den pulsierenden heißen Gasstrom eingespritzt werden. Die beschriebene Norrichtung ist technisch aufwendig und erfordert zusätzlich die Mitführung von flüssigem Brennstoff.For this purpose, the decontamination solution is sprayed onto the object to be decontaminated, for example by means of a spray device with the aid of a device operating according to the pulsation method, as is e.g. is described in DE 41 04 134 C2. For this purpose, the device described in the document for applying the decontamination solution comprises a combustion chamber in which a gasoline-air mixture is ignited and the droplets of the decontamination solution are injected into the pulsating hot gas stream. The described direction is technically complex and additionally requires the carrying of liquid fuel.
Weiterhin ist es bekannt, die Dekontaminationslösung mit Hilfe eines Lappens von Hand auf das zu dekontaminierende Objekt aufzutragen. Dabei ergibt sich das Problem, dass das Tuch nur einseitig benutzt werden kann, da andernfalls die zuerst benutzte, bereits mit Schadstoffen verunreinigte Seite des Lappens bei der Reinigung mit der zweiten Seite unmittelbar mit der Hand des Benutzers des Tuchs in Kontakt gelangt, was nicht nur zu einer erhöhten Verunreinigung der Schutzbekleidung führt, welche die Hand des Benutzers während des Dekontaminationsvorgangs schützt, sondern zusätzlich die Gefahr erhöht, dass der Benutzer mit den Schadstoffen direkt in Kontakt gelangt oder diese verschleppt.It is also known to apply the decontamination solution to the object to be decontaminated by hand using a cloth. The problem arises here that the cloth can only be used on one side, since otherwise the first side of the cloth that has already been contaminated with pollutants comes into direct contact with the hand of the user of the cloth during cleaning, which not only leads to increased contamination of the protective clothing, which protects the hand of the user during the decontamination process, but additionally increases the risk of the user coming into direct contact with the contaminants or being carried over.
BESTÄTIGUΝGSK PI Demgemäß ist es eine Aufgabe der vorliegenden Erfindung, ein Norrichtung zum Aufbringen von Dekontaminationsflussigkeit zu schaffen, welche die zuvor beschriebenen Nachteile des Standes der Technik vermeidet, leicht zu bedienen und zu handhaben ist, und welche ein zielgenaues flächiges Aufbringen von Dekontaminationsflussigkeit in kurzer Zeit ermöglicht.CONFIRMATION PI Accordingly, it is an object of the present invention to provide a device for applying decontamination liquid which avoids the disadvantages of the prior art described above, is easy to use and handle and which enables precise application of decontamination liquid in a short time.
Diese Aufgabe wird gemäß der Erfindung durch die Merkmale von Anspruch lgelöst.This object is achieved according to the invention by the features of claim.
Weitere Merkmale der Erfindung sind in den Unteransprüchen enthalten.Further features of the invention are contained in the subclaims.
Die Erfindung wird nachfolgend mit Bezug auf die Zeichnung anhand einer bevorzugten Ausführungsform beschrieben.The invention is described below with reference to the drawing based on a preferred embodiment.
In den Zeichnungen zeigtIn the drawings shows
Fig. 1 eine schematische Darstellung eines erfindungsgemäßenFig. 1 is a schematic representation of an inventive
Dekontaminationsflüssigkeits-Sprühgerätes, welches in einer Gürteltasche aufgenommen ist.Decontamination liquid sprayer, which is accommodated in a belt pouch.
Wie in der einzigen Fig. 1 gezeigt ist, umfasst das erfindungsgemäße Dekontaminationsflüssigkeits-Sprühgerät 1 einen Druckbehälter 2, in dem sich Dekontaminationsflussigkeit 4, insbesondere GD-5 Dekontaminationslösung, befindet.As shown in the only FIG. 1, the decontamination liquid spray device 1 according to the invention comprises a pressure container 2 in which decontamination liquid 4, in particular GD-5 decontamination solution, is located.
Das erfindungsgemäße Dekontaminationsflüssigkeits-Sprühgerät 1 umfasst weiterhin einen Adapterkopf 6, der mit einem Außengewindeabschnitt 8 versehen ist, der in eine zugehörige Innengewindeöffnung 10 an der Oberseite des Druckbehälters 2 einschraubbar ist. Die Ausbildung der Gewinde ist dabei derart gewählt, dass innerhalb des Druckbehälters 2 ein Überdruck von z.B. 6 bar oder mehr aufgebaut und gehalten werden kann.The decontamination liquid spray device 1 according to the invention further comprises an adapter head 6 which is provided with an external thread section 8 which can be screwed into an associated internal thread opening 10 on the top of the pressure vessel 2. The design of the thread is chosen such that an overpressure of e.g. 6 bar or more can be built and held.
Zur Erzeugung des Überdrucks ist am Adapterkopf 6 eine Luftpumpe 12 vorgesehen, die ein sich von der Unterseite des Adapterkopfes 6 aus in das Innere des Druckbehälters 2 hinein erstreckendes Pumpenrohr 14 umfasst, in welchem ein Pumpenkolben 16 über eine Kolbenstange 18 auf- und nieder bewegbar ist, um Luft von außen her anzusaugen und durch ein in Fig. 1 lediglich schematisch gezeigtes Rückschlagventil 20 am unteren Ende des Pumpenrohres 14 in den Innenraum des Druckbehälters 2 zu pressen. Das andere Ende der Kolbenstange 18 ist hierzu mit einem Zug- und Druckknopf 22 versehen, der bei vollständig eingeschobenem Pumpenkolben 16 vorzugsweise an der Oberseite des Adapterkopfes 6 aufliegt. Durch Auf- und Niederbewegen des Pumpenkolbens 16 mittels des Zug- und Druckknopfes 22 kann der Benutzer des erfindungsgemäßen Dekontaminationsflüssigkeits-Sprühgerätes 1 somit per Hand einen Überdruck von ca. 6 bar im Druckbehälter 2 erzeugen, der die Dekontaminationsflussigkeit 4 durch ein am Adapterkopf 6 befestigtes Steigrohr 24 zu einem am Adapterkopf 6 angeordneten Regulierventil 26 und von diesem aus über eine im Adapterkopf 6 gebildete Druckleitung 28 zu einem Flüssigkeitsauslaß 30 fördert.To generate the excess pressure, an air pump 12 is provided on the adapter head 6, which extends from the underside of the adapter head 6 into the interior of the pressure container 2 extends into the pump tube 14, in which a pump piston 16 can be moved up and down via a piston rod 18 in order to suck in air from the outside and through a check valve 20, which is only shown schematically in FIG. 1, at the lower end of the pump tube 14 into the interior of the Press container 2. For this purpose, the other end of the piston rod 18 is provided with a pull and push button 22, which preferably rests on the upper side of the adapter head 6 when the pump piston 16 is fully inserted. By moving the pump piston 16 up and down by means of the pull and push button 22, the user of the decontamination liquid spray device 1 according to the invention can thus manually generate an excess pressure of approximately 6 bar in the pressure container 2, which releases the decontamination liquid 4 through a riser pipe attached to the adapter head 6 24 to a regulating valve 26 arranged on the adapter head 6 and from there to a liquid outlet 30 via a pressure line 28 formed in the adapter head 6.
Über das Regulierventil 26, z.B. ein in Fig. 1 schematisch angedeutetes Nadelventil, kann der Druck und die Menge der dem Flüssigkeitsauslaß 30 zugeführten Dekontaminationsflussigkeit 4 von Hand reguliert werden.Via the regulating valve 26, e.g. a needle valve schematically indicated in FIG. 1, the pressure and the amount of the decontamination liquid 4 supplied to the liquid outlet 30 can be regulated by hand.
Wie in Fig. 1 weiterhin gezeigt ist, ist der Flüssigkeitsauslaß 30 strömungsmäßig mit einem flexiblen Schlauch 32 verbunden, an dessen anderem Ende eine Sprühdüse 34 angeordnet ist, die über ein schematisch dargestelltes Auf-Zu-Ventil 36 mit Dekontaminationsflussigkeit 4 beaufschlagbar ist, um diese durch die Sprühdüse 34 hindurch zu versprühen. Der flexible Schlauch 32 erstreckt sich dabei vorzugsweise vom Flüssigkeitsauslaß 30 nach unten weg, so dass dieser problemlos aufgerollt in dem entsprechenden freien Innenbereich einer Tasche 38 aufgenommen werden kann, in der das erfindungsgemäße Gerät 1 vorzugsweise derart untergebracht wird, dass der Adapterkopf 6 zusammen mit dem Regulierventil 26 und dem Zug- und Druckknopf 22 aus einer zugehörigen Öffnung 40 an der Oberseite der Tasche 38 herausragt. Hierdurch kann der Benutzer des Gerätes die Menge der Dekontaminationsflussigkeit 4 regulieren und ggf. den Druck im Druckbehälter 2 durch Betätigen der Luftpumpe 12 über den Zug- und Druckknopf 22 erhöhen. Die Tasche 38 ist vorzugsweise mittels nicht näher dargestellter Halteschlaufen am Hosengürtel des Benutzers befestigbar, oder ist mit einem Umhängeriemen versehen, so dass der Benutzer die Tasche 38 bei der Benutzung des erfindungsgemäßen Geräts 1 über seine Schulter hängen kann. Hierbei kann es weiterhin vorgesehen sein, dass in Höhe der ersten Öffnung 40 an der Oberseite der Tasche eine weitere Öffnung 42 vorgesehen ist, durch die hindurch der Benutzer den flexiblen Schlauch 32 mit der daran befestigten Sprühdüse 34 herausziehen kann, um die Dekontaminationsflussigkeit 4 zielgerichtet zu versprühen.As is further shown in FIG. 1, the liquid outlet 30 is connected in terms of flow with a flexible hose 32, at the other end of which a spray nozzle 34 is arranged, which can be acted upon with decontamination liquid 4 via a schematically illustrated open-close valve 36 to spray through the spray nozzle 34. The flexible hose 32 preferably extends downward from the liquid outlet 30, so that it can be rolled up and easily accommodated in the corresponding free inner region of a pocket 38 in which the device 1 according to the invention is preferably accommodated in such a way that the adapter head 6 together with the Regulating valve 26 and the pull and push button 22 protrude from an associated opening 40 on the top of the pocket 38. As a result, the user of the device can regulate the amount of decontamination liquid 4 and, if necessary, increase the pressure in the pressure vessel 2 by actuating the air pump 12 via the pull and push button 22. The bag 38 can preferably be fastened to the user's belt by means of holding loops (not shown in more detail) or is provided with a shoulder strap so that the user can hang the bag 38 over his shoulder when using the device 1 according to the invention. It can further be provided that at the level of the first opening 40 at the top of the pocket there is a further opening 42 through which the user can pull out the flexible hose 32 with the spray nozzle 34 attached to it in order to target the decontamination liquid 4 spray.
Das erfindungsgemäß Dekontaminationsflüssigkeits-Sprühgerät 1 besitzt den Vorteil, dass es eine sehr kompakte und robuste Bauweise aufweist, und bei einer entsprechenden Dimensionierung des Druckbehälters 2 - beispielsweise als flaschenförmiger Behälter mit 1, 2 oder 3 Litern Fassungsvermögen - bequem als Gürteltasche getragen und zum Einsatz, bzw. zum Befallen, einfach und schnell aus der Gürteltasche entnommen werden kann. Die kompakte Bauweise bietet ebenfalls den Vorteil, dass das Gerät auch in sehr engen Räumlichkeiten verwendet werden kann, in denen ein Einsatz von größeren Geräten aus Platzgründen nicht oder nur sehr mühsam möglich ist.The decontamination liquid spray device 1 according to the invention has the advantage that it has a very compact and robust construction, and with a corresponding dimensioning of the pressure container 2 - for example as a bottle-shaped container with a capacity of 1, 2 or 3 liters - is conveniently carried and used as a belt pouch, or for infestation, can be easily and quickly removed from the belt bag. The compact design also offers the advantage that the device can also be used in very confined spaces where larger devices cannot be used, or only with great difficulty, for reasons of space.
Schließlich lässt sich der Druckbehälter 2 bei der bevorzugten Ausführungsform der Erfindung, bei der ein möglichst breiter Adapterkopf 6 zum Einsatz gelangt, durch die Gewindeoffnung 10 hindurch sehr leicht und verlustfrei befüllen, und entsprechend auch wieder entleeren und reinigen. Finally, in the preferred embodiment of the invention, in which the widest possible adapter head 6 is used, the pressure vessel 2 can be filled very easily and without loss through the threaded opening 10, and correspondingly emptied and cleaned again.
