Description
Die Erfindung betrifft eine Druckluftbetriebene Reinigungspistole mit einem ein Reinigungsmittel enthaltenden Reinigungsbehälter gemäß Oberbegriff des Anspruchs 1.The invention relates to a compressed air operated cleaning gun with a Cleaning container containing detergent according to the preamble of the claim 1.
Zum Reinigen von Abflussrohren, von Wänden und dergleichen werden Reinigungspistolen verwendet, die einen Pistolengriff und ein mittels eines Handhebels betätigbares Druckluftventil besitzen. Eine solche Reinigungspistole kann einen Reinigungsbehälter mit einer Reinigungsflüssigkeit haben, aus dem mittels Unterdruck die Reinigungsflüssigkeit angesaugt wird, so dass die Druckluft vermischt mit der Reinigungsflüssigkeit an einer Düse oder einer entsprechend ausgebildeten Auslassöffnung in Form eines Reinigungsstrahls austritt. Um einen geeigneten Reinigungsschaum zu erzielen, kann im Bereich der Auslassöffnung ein feinmaschiges Sieb angeordnet sein, wie dies aus dem deutschen Gebrauchsmuster 298 22 384 bekannt ist.For cleaning drain pipes, walls and the like Cleaning guns are used that have a pistol grip and a means of a hand lever have actuatable compressed air valve. Such a cleaning gun can Have cleaning containers with a cleaning liquid from which by means of negative pressure the cleaning liquid is sucked in so that the compressed air mixes with the Cleaning liquid on a nozzle or an appropriately trained Outlet opening in the form of a cleaning jet emerges. To a suitable one Achieving cleaning foam can be a fine mesh in the area of the outlet opening Sieve can be arranged, as is from German utility model 298 22 384 is known.
Die bekannten Reinigungspistolen können als Reinigungsmittel nur Flüssigkeiten verwenden, während pastöse oder thixotrope Reinigungsmittel in herkömmlicher Weise mit einem Pinsel oder einem Spachtel auf die zu reinigenden Oberflächen aufgetragen werden müssen. Derart zähflüssige Reinigungsmittel werden insbesondere zur Entfernung von auf Wänden aufgesprühten Farbverunreinigungen verwendet.The known cleaning guns can only use liquids as cleaning agents use while pasty or thixotropic detergents in conventional Apply a brush or spatula to the surfaces to be cleaned must be applied. Such viscous cleaning agents are particularly used to remove paint stains sprayed on walls.
Der Erfindung liegt die Aufgabe zugrunde, eine Druckluftbetriebene Reinigungspistole zu schaffen, mit der auch zähflüssige Reinigungsmittel im Druck-Spritzverfahren auf zu reinigende Oberflächen aufgetragen werden können. The invention has for its object a compressed air operated cleaning gun to create with the viscous cleaning agent in the pressure spraying process surfaces to be cleaned can be applied.
Die Lösung dieser Aufgabe erhält man durch die im Anspruch 1 angegebenen Merkmale. Das thixotrope oder pastöse Reinigungsmittel wird mittels Unterdruck in einen Mischraum angesaugt, der einen zur Auslassöffnung führenden Auslassabschnitt mit vergrößertem Innendurchmesser besitzt. Versuche haben gezeigt, dass mit einem derart sich aufweitenden Mischraum, insbesondere in Verbindung mit einer auf das Ende der Druckluftleitung aufgesetzten Expansionsdüse, ein optimaler Reinigungsstrahl erzeugt werden kann. Vorteilhaft ist in diesem Zusammenhang auch die Tatsache, dass das zähflüssige Reinigungsmittel nicht mit Überdruck aus dem Reinigungsbehälter herausbefördert werden muss, sondern dass dies mittels Unterdruck im Saugverfahren über ein in den Reinigungsbehälter ragendes Saugrohr erfolgen kann. Der Reinigungsbehälter ist somit keinem Überdruck ausgesetzt, wodurch eine höhere Sicherheit beim Betrieb erreicht wird. Die aggressiven Reinigungsmittel, die zur Entfernung von auf Wänden mittels Lackspray aufgesprühten Farbverunreinigungen geeignet sind, dürfen keinesfalls mit der Haut der Bedienperson in Berührung kommen, weshalb es außerdem sehr günstig ist, handelsübliche Reinigungsbehälter im Austausch zu verwenden, ohne dass ein Umfüllen des Reinigungsmittels erforderlich ist.The solution to this problem is obtained by the specified in claim 1 Characteristics. The thixotropic or pasty cleaning agent is vacuumed in a mixing space is sucked in, an outlet section leading to the outlet opening with an enlarged inner diameter. Trials have shown that with a such widening mixing room, especially in connection with one on the Expansion nozzle attached to the end of the compressed air line, an optimal one Cleaning jet can be generated. It is also advantageous in this context the fact that the viscous detergent is not under pressure from the Cleaning container must be conveyed out, but that by means of Vacuum in the suction process via a suction pipe protruding into the cleaning container can be done. The cleaning container is therefore not exposed to excess pressure, thereby achieving a higher level of security during operation. The aggressive ones Detergents that are sprayed on walls with a paint spray Color impurities are not allowed on the operator's skin come into contact, which is why it is also very cheap, commercially available Use the cleaning container in exchange without having to refill the Detergent is required.
Die im Düsenrohr der Reinigungspistole sich erstreckende Druckluftleitung kann an ihrem vorderen Ende eine Querschnittserweiterung haben, und zwar vorzugsweise in Form einer Expansionsdüse, die im Bereich der Querschnittserweiterung mit Durchbrechungen versehen ist.The compressed air line extending in the nozzle tube of the cleaning gun can be on have a cross-sectional expansion at their front end, preferably in Form of an expansion nozzle, which in the area of cross-sectional expansion with Breakthroughs is provided.
Ein besonders gut geeigneter Reinigungsstahl wurde unter Verwendung einer Expansionsdüse erreicht, die mit der Druckluftleitung über ein Anschlussrohrstück verbunden war und ein sich zum Ende hin koaxial ausgerichtetes Zentrierstück mit größerem Innendurchmesser besaß. Im Anschlussrohrstück und in der Ringwand zwischen Anschlussrohrstück und dem Zentrierstück befanden sich über den Umfang verteilte Durchbrechungen, durch die das zähflüssige Reinigungsmittel optimal angesaugt wurde. Je nach Abstand von der Wandoberfläche konnte mit einer derartigen Ausführung einer Reinigungspistole ein 4cm bis 10cm breiter Reinigungsstrahl eines Reinigungsgemischs aufgetragen werden. Das Reinigungsgemisch ist aufgrund der Zähflüssigkeit des Reinigungsmittels ebenfalls so zähflüssig, dass es auf Mauerwerk sicher anhaftet, ohne zu tropfen.A particularly suitable cleaning steel was used using a Expansion nozzle reached with the compressed air line via a connecting pipe piece was connected and a centering piece coaxially aligned towards the end had a larger inner diameter. In the connecting pipe section and in the ring wall between the connecting pipe piece and the centering piece were on the circumference distributed openings through which the viscous cleaning agent is optimal was sucked in. Depending on the distance from the wall surface, one could such execution of a cleaning gun a 4cm to 10cm wider Cleaning jet of a cleaning mixture can be applied. The Cleaning mixture is also like this due to the viscosity of the cleaning agent viscous that it sticks securely to masonry without dripping.
Die Querschnittserweiterung der Expansionsdüse hat vorzugsweise einen Außendurchmesser, der dem Innendurchmesser des Saugkanals entspricht. Dadurch bildet die Querschnittserweiterung mit ihrem vorderen Ende ein Zentrierelement, welches die Expansionsdüse und den an ihr angeschlossenen Druckschlauch im Saugkanal zentriert.The cross-sectional expansion of the expansion nozzle preferably has one Outer diameter that corresponds to the inner diameter of the suction channel. Thereby the cross-sectional extension forms a centering element with its front end, which the expansion nozzle and the pressure hose connected to it in the Centered suction channel.
Der Mischraum befindet sich vorzugsweise in einem an einem Grundkörper der Reinigungspistole angeschlossenen Düsenrohr, welches ebenso wie der Druckschlauch abnehmbar am Grundkörper angebracht sein kann.The mixing space is preferably located in a on a base body Cleaning gun connected nozzle tube, which as well as the pressure hose can be removably attached to the base body.
Bei der Verwendung eines thixotropen Reinigungsmittels und einem Düsenrohr mit einer Länge von 10cm bis 20cm wird eine gute Saug- und Sprühleistung erreicht, wenn die Länge des Auslassabschnitts 20mm und der Abstand zwischen dem Ende der Druckluftleitung und dem Auslassabschnitt 10mm betragen. Bei diesen Abmessungen ist es weiterhin vorteilhaft, den Innendurchmesser des Auslassabschnitts mit 8,5mm, den Innendurchmesser des Saugkanals mit 6,0mm und den Außendurchmesser der im Saugkanal verlaufenden Druckleitung mit 4,0mm auszuführen.When using a thixotropic cleaning agent and a nozzle tube with a length of 10cm to 20cm a good suction and spraying performance is achieved if the length of the outlet section 20mm and the distance between the end of the Compressed air line and the outlet section are 10mm. With these dimensions it is also advantageous to adjust the inside diameter of the outlet section to 8.5 mm, the inner diameter of the suction channel with 6.0mm and the outer diameter of the Suction channel running pressure line with 4.0mm.
Die Reinigungspistole kann an den Teilen, die mit dem aggressiven Reinigungsmitteln in Berührung kommen, aus säurebeständigem Kunststoff hergestellt sein, wobei das Düsenrohr allerdings vorzugsweise aus Edelstahl bestehen sollte. The cleaning gun can be attached to the parts with the aggressive cleaning agent come into contact, be made of acid-resistant plastic, which However, the nozzle tube should preferably be made of stainless steel.
