Description

Die vorliegende Erfindung betrifft eine Reinigungsvorrichtung für Zerstäuber, insbesondere Farbspritzpistolen, nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Reinigung eines Zerstäubers.The present invention relates to a cleaning device for atomizers, in particular paint spray guns, according to the preamble of claim 1 and a method for cleaning an atomizer.

Zerstäuber werden zum Auftragen von Fluiden, beispielsweise Lacken oder Beschichtungen auf einen Gegenstand, beispielsweise eine Fahrzeugkarosserie, verwendet. Mittels des Zerstäubers wird aus einem Fluid ein feiner Nebel des Fluides erzeugt, der auf den Gegenstand aufgetragen werden kann. Sofern es sich bei dem Zerstäuber um ein handbetätigtes Gerät zum Auftragen von Lacken handelt wird dieses, wegen der an eine Schusswaffe erinnernde Form, oft als Farbspritzpistole bezeichnet. Im industriellen Einsatz auf automatischen Lackieranlagen kommen die Zerstäuber an Robotern als Luft-(Kappen)-Zerstäuber oder Glocken, sowie mit Außenelektroden mit anschließendem Trockenblasen zum Einsatz. Die zuvor beschriebenen Zerstäuber müssen jedoch regelmäßig gereinigt werden, d.h. von Resten des ggf. bereits angetrockneten Fluids befreit werden. Insbesondere müssen bereits angetrocknete Farbreste von dem Zerstäuber entfernt werden. Hierzu sind Vorrichtungen aus dem Stand der Technik bekannt geworden.Atomizers are used to apply fluids, such as paints or coatings, to an article, such as a vehicle body. By means of the atomizer, a fluid generates a fine mist of the fluid which can be applied to the object. If the atomizer is a hand-operated apparatus for applying paints, it is often referred to as a paint spray gun because of the shape reminiscent of a firearm. In industrial use on automatic painting plants, the atomizers are used on robots as air (cap) atomizers or bells, as well as with external electrodes followed by dry blowing. However, the sprayers described above must be cleaned regularly, i. be removed from residues of the possibly already dried fluid. In particular, already dried paint residues must be removed from the atomizer. For this purpose, devices have become known from the prior art.

Die GB 2 198 033 A offenbart eine Reinigungsvorrichtung für Zerstäuber der eingangs genannten Art.The GB 2 198 033 A discloses a cleaning device for atomizers of the type mentioned.

Aus der EP 0 869 848 B1 ist eine Vorrichtung zum Reinigen von Spritzpistolen, umfassend einen geschlossenen Behälter mit einem Einlass, einem Auslauf und einer Öffnung zum Aufnehmen einer Düse einer Spritzpistole, eine Sprayvorrichtung, die in dem genannten Behälter drehbar montiert ist und sich mit dem genannten Einlass in Fluidkommunikation befindet bekannt geworden, wobei die genannte Sprayvorrichtung eine versetzte Reinigungsdüse zum Spritzen eines Reinigungssprays auf die genannte Öffnung zu und eine Rotationsvorrichtung zum Bewirken der Rotation der genannten Sprayvorrichtung hat, wobei die genannte Öffnung eine. Dichtungsvorrichtung zum abdichtenden Aufnehmen der genannten Spritzpistolen und zum Positionieren der genannten Düse der genannten Spritzpistolen in dem genannten Reinigungsspray hat, wobei die Rotationsvorrichtung eine Rotationsdüse zum Spritzen eines Rotationssprays aufweist.From the EP 0 869 848 B1 is an apparatus for cleaning spray guns comprising a closed container having an inlet, a spout and an opening for receiving a nozzle of a spray gun, a spray device rotatably mounted in said container and having said inlet in fluid communication wherein said spray device has a staggered cleaning nozzle for spraying a cleaning spray onto said opening and a rotating device for effecting rotation of said spray device, said opening having a. A sealing device for sealingly receiving said spray guns and for positioning said nozzle of said spray guns in said cleaning spray, said rotating device having a rotary nozzle for spraying a rotary spray.

Zwar ist die zuvor genannte Vorrichtung zum Reinigen von Spritzpistolen, insbesondere Farbspritzpistolen, geeignet, es ist jedoch nachvollziehbar, dass die Mechanik und die Dichtungstechnik fĂĽr die beschriebene Rotationsvorrichtung entsprechend aufwendig ist.Although the aforementioned device is suitable for cleaning spray guns, in particular paint spray guns, it is, however, comprehensible that the mechanics and the sealing technology for the rotary device described are correspondingly expensive.

Es sind ferner Reinigungsvorrichtungen bekannt geworden, die nicht über eine Rotationsvorrichtung verfügen. Beispielsweise offenbart die DE 101 10 098 A1 eine Reinigungsvorrichtung für Farbaustraggeräte, mit mindestens einem Reinigungsbehälter, in den zu reinigende Teile des Farbaustraggerätes steckbar sind, wobei im Reinigungsbehälter wenigstens eine Zuleitung vorgesehen ist, die wenigstens einen gegen die zu reinigenden Teile gerichteten Austritt für das Reinigungsmittel aufweist. Die hier beschriebene Reinigungsvorrichtung weist ferner eine Vielzahl von Düsen auf, wobei den Düsen das Reinigungsmittel unter Druck zugeführt wird. Zwar zeichnet sich die Reinigungsvorrichtung durch einen einfachen Aufbau aus, insbesondere sind keine rotierenden Düsen vorgesehen, jedoch muss eine erhebliche Anzahl von Düsen vorgesehen sein, um das Farbaustraggerät allseitig von Farbresten zu befreien. Es ist nachvollziehbar, dass hieraus ein erheblicher Reinigungsmittelverbrauch resultiert, der sowohl unter Kostengesichtspunkten, wie auch ökologischen Gesichtspunkten nicht erwünscht ist.There are also known cleaning devices that do not have a rotary device. For example, the DE 101 10 098 A1 a cleaning device for Farbaustraggeräte, with at least one cleaning container, are plugged into the parts to be cleaned of the Farbaustraggerätes, wherein in the cleaning container at least one supply line is provided which has at least one directed against the parts to be cleaned outlet for the cleaning agent. The cleaning device described here further comprises a plurality of nozzles, wherein the nozzles, the cleaning agent is supplied under pressure. Although the cleaning device is characterized by a simple construction, in particular no rotating nozzles are provided, however, a considerable number of nozzles must be provided in order to free the paint discharge device on all sides from paint residues. It is understandable that this results in a significant consumption of cleaning agents, which is undesirable from the point of view of both cost and environmental aspects.

Aus der US 3,771,539 ist eine Reinigungsvorrichtung für Farbspritzpistolen bekannt, bei der das Reinigungsmedium mit Hilfe von Schläuchen in den Reinigungsbehälter, in der sich die Farbspritzpistole befindet, geleitet wird. Die DE 26 55 875 A1 offenbart einen Mehrdüsenblock zum Bestäuben von Werkzeugoberflächen, bei dem die zu zerstäubenden Produkte aus zwei Zuleitungen und durch zwei diesen zugeordnete Steuerventile in zwei Leitungen eingelassen werden. Dort werden sie durch komprimierte Luft zerstäubt und anschließend Düsen zugeführt, die aus einem eingepressten oder eingeschweißten Kupferrohr hergestellt sind.From the US 3,771,539 a cleaning device for paint spray guns is known, in which the cleaning medium by means of hoses in the cleaning container in which the paint spray gun is passed. The DE 26 55 875 A1 discloses a multi-nozzle block for dusting tool surfaces, in which the products to be sputtered from two supply lines and by two associated with these control valves are inserted into two lines. There they are atomized by compressed air and then fed nozzles, which are made of a pressed or welded copper pipe.

Hier setzt die vorliegende Erfindung an und macht es sich zur Aufgabe, eine Reinigungsvorrichtung vorzuschlagen, die sich durch einen einfachen Aufbau, eine hohe Reinigungswirkung und einen geringen Wartungsaufwand auszeichnet.This is where the present invention sets and makes it its mission to propose a cleaning device which is characterized by a simple structure, a high cleaning effect and low maintenance.

Erfindungsgemäß wird diese Aufgabe durch eine Reinigungsvorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Dadurch, dass die Mischeinrichtung dazu eingerichtet ist, die Druckluft mit einer Druckdifferenz gegenüber dem Reinigungsmittel dem Gemischausgang zuzuführen, wobei die Mischeinrichtung ferner dazu eingerichtet ist, die Druckluft mit einem höheren Druck als das Reinigungsmittel dem Gemischausgang zuzuführen, wird ein Vaporisierungseffekt erzielt, d.h. die Oberfläche, sowie das Volumen des Reinigungsmittels wird um ein Vielfaches erhöht, so dass ein maximaler Reinigungserfolg mit niedrigstem Verbrauch an Reinigungsmittel in kürzester Reinigungszeit im Verhältnis zu bekannten Reinigungsmethoden und Reinigungsvorrichtungen erzielt werden kann. Eine vorgeschlagene Reinigungsvorrichtung ermöglicht eine Einsparung an Druckluft als auch Reinigungsmittel von bis zu 90%. Der Verbrauch an Reinigungsmittel beträgt nur etwa 6 bis 10ml pro Reinigungsvorgang für eine Sprühpistole. Zur Erhöhung der Reinigungswirkung ist erfindungsgemäß vorgesehen, dass als Sprüheinrichtung ein erstes und ein zweites Spülrohr vorgesehen sind, wobei die Spülrohre in das Gehäuse hineinragen, wobei die Spülrohre eine geometrische Längsachse aufweisen und wobei die Spülrohre derart auf die Zerstäuberaufnahme ausgerichtet sind, dass sich die geometrischen Längsachsen im Mittelpunkt der Zerstäuberaufnahme kreuzen. Dadurch, dass an Stelle von Düsen Spülrohre, sprich Rohre mit einem in Längsrichtung gleichbleibenden Querschnitt, verwendet werden, die dazu eingerichtet sind, die Mischung aus Druckluft und Reinigungsmittel auf den zu reinigenden Zerstäuber zu versprühen, ist die Gefahr, dass sich ein derartiges Spülrohr, beispielsweise durch angetrocknete Lackreste, zusetzt, erheblich geringer.According to the invention this object is achieved by a cleaning device with the characterizing features of claim 1. Characterized in that the mixing device is adapted to supply the compressed air with a pressure difference compared to the cleaning agent to the mixture output, wherein the mixing device is further adapted to supply the compressed air at a higher pressure than the cleaning agent to the mixture output, a Vaporisierungseffekt is achieved, ie the surface , As well as the volume of the cleaning agent is increased many times, so that a maximum cleaning success with the lowest consumption of detergent in the shortest cleaning time in proportion to known cleaning methods and cleaning devices can be achieved. A proposed cleaning device allows a saving of compressed air and cleaning agent of up to 90%. The consumption of detergent is only about 6 to 10ml per cleaning process for a spray gun. To increase the cleaning effect, the invention provides that a first and a second flushing pipe are provided as spraying device, wherein the flushing pipes protrude into the housing, wherein the flushing pipes have a geometric longitudinal axis and wherein the flushing pipes are aligned with the atomizer so that the geometric Cross longitudinal axes in the center of the atomizer receptacle. The fact that, instead of nozzles, use is made of rinsing pipes, that is to say pipes having a longitudinally constant cross-section, which are arranged to spray the mixture of compressed air and cleaning agent onto the atomizer to be cleaned, the risk of such a flushing pipe, for example, by dried-on paint residues, added considerably less.

In einer vorteilhaften Ausgestaltung der vorgeschlagenen Reinigungsvorrichtung kann vorgesehen sein, dass die Mischeinrichtung dazu eingerichtet ist, die Druckluft mit einer Druckdifferenz von 2 bis 4, vorzugsweise 3 bar gegenĂĽber dem Reinigungsmittel dem Gemischausgang zuzufĂĽhren. Bei einer Druckdifferenz von 3 bar ergeben sich besonders gute Reinigungsergebnisse.In an advantageous embodiment of the proposed cleaning device can be provided that the mixing device is adapted to supply the compressed air with a pressure difference of 2 to 4, preferably 3 bar compared to the cleaning agent to the mixture output. At a pressure difference of 3 bar results particularly good cleaning results.

Es kann weiterhin vorteilhafterweise vorgesehen sein, dass die Mischeinrichtung dazu eingerichtet ist, das Reinigungsmittel dem Gemischausgang mit einem Druck von etwa 1 bar und die Druckluft dem Gemischausgang mit einem Druck von etwa 4 bar zuzufĂĽhren. Bei diesen DrĂĽcken und der sich ergebenden Druckdifferenz wurden besonders gute Reinigungsergebnisse erzielt.It may also be advantageously provided that the mixing device is adapted to supply the detergent to the mixture outlet at a pressure of about 1 bar and the compressed air to the mixture outlet at a pressure of about 4 bar. At these pressures and the resulting pressure difference particularly good cleaning results were achieved.

In einer weiteren vorteilhaften Ausgestaltung der vorliegenden Erfindung kann vorgesehen sein, dass die Mischeinrichtung dazu eingerichtet ist, das Reinigungsmittel dem Gemischausgang mit einem Druck von etwa 2 bar und die Druckluft dem Gemischausgang mit einem Druck von etwa 5 bar zuzufĂĽhren. Bei diesen DrĂĽcken und der sich ergebenden Druckdifferenz wurden besonders gute Reinigungsergebnisse erzielt.In a further advantageous embodiment of the present invention can be provided that the mixing device is adapted to supply the cleaning agent to the mixture outlet at a pressure of about 2 bar and the compressed air to the mixture outlet at a pressure of about 5 bar. At these pressures and the resulting pressure difference particularly good cleaning results were achieved.

Es kann weiterhin vorteilhafterweise vorgesehen sein, dass zwischen dem Reinigungsmitteleingang und dem Gemischausgang eine DĂĽse vorgesehen ist, wobei die DĂĽse einen Durchmesser von 0,5 bis 2 mm aufweist. Durch eine derartige DĂĽse zwischen Reinigungsmitteleingang und Gemischausgang kann im Wesentlichen sichergestellt werden, dass die bevorzugte Druckdifferenz von 3 bar hergestellt werden kann.It may also be advantageously provided that between the detergent inlet and the mixture outlet, a nozzle is provided, wherein the nozzle has a diameter of 0.5 to 2 mm. Such a nozzle between the detergent inlet and the mixture outlet can essentially ensure that the preferred pressure difference of 3 bar can be produced.

Die Spülrohre 1, 2 sind derart auf die Zerstäuberaufnahme 3 ausgerichtet, dass ein aus den Spülrohren 1, 2 austretendes Druckluft-Reinigungsmittel-Gemisch einen in der Zerstäuberaufnahme 3 aufgenommenen Zerstäuber 8 erreichen kann. Eine erfindungsgemäße Reinigungsvorrichtung umfasst weiterhin eine Mischeinrichtung 9 mit einem Drucklufteingang 10, einem Reinigungsmitteleingang 11 und einem Gemischausgang 12. Die Mischeinrichtung 9 ist dazu geeignet, das über den Reinigungsmitteleingang 11 zugeführte, vorzugsweise flüssige Reinigungsmittel mit der über den Drucklufteingang zugeführten Luft zu mischen und das entstehende Druckluft-Reinigungsmittel-Gemisch aus dem Gemischausgang 12 abzugeben, wobei die Spülrohre 1, 2 über geeignete Zuleitungen 16 mit dem Gemischausgang 12 verbunden sind, so dass das Druckluft-Reinigungsmittel-Gemisch letztendlich über die Spülrohre 1, 2 abgegeben werden kann.A cleaning device according to the invention essentially comprises a nebulizer receptacle 3, a first flushing pipe 1 and a second flushing pipe 2. The flushing pipes 1, 2 are aligned with the atomizing receptacle 3 in such a way that a compressed air / cleaning agent mixture emerging from the flushing pipes 1, 2 opens in the compressed air cleaning agent mixture Atomizer 3 recorded atomizer 8 can reach. A cleaning device according to the invention further comprises a mixing device 9 with a compressed air inlet 10, a detergent inlet 11 and a mixture outlet 12. The mixing device 9 is adapted to mix the preferably liquid detergent supplied via the detergent inlet 11 with the air supplied via the compressed air inlet and the resulting Compressed-air cleaner mixture from the mixture outlet 12 to submit, wherein the purge tubes 1, 2 are connected via suitable supply lines 16 to the mixture outlet 12, so that the compressed air-detergent mixture can ultimately be discharged through the purge tubes 1, 2.

Es ist ferner ein Gehäuse 5, sowie ein Deckel 4 vorgesehen, wobei der Deckel 4 zur Aufnahme der Zerstäuberaufnahme 3 und das Gehäuse 5 zur Aufnahme der Spülrohre 1, 2 eingerichtet ist.Furthermore, a housing 5 and a cover 4 are provided, the cover 4 being adapted to receive the atomizer receptacle 3 and the housing 5 to receive the flushing pipes 1, 2.

Das Gehäuse 3 ist im wesentlichen hohlzylinderförmig ausgestaltet und kopfseitig mit einem umlaufenden kragen 18 ausgestattet. Die Spülrohre 1, 2 ragen auf gegenüberfiegenden Seiten in das hohlzylinderförmige Gehäuse 5 hinein und weisen eine geeignete Biegung auf, um die Spülrohre 3, 4 in Richtung der Zerstäuberaufnahme 3 auszurichten, die an dem Deckel 4 angebracht ist. Eine geometrische Längsachse der Spülrohre 1, 2 ist entsprechend auf den Mittelpunkt der Zerstäuberaufnahme 3 ausgerichtet. Sofern, wie hier vorgeschlagen, von zwei Spülrohren ausgegangen wird, kreuzen sich die Längsachsen der Sprührohe 1, 2 im Mittelpunkt der Zerstäuberaufnahme 3. Das Gehäuse 5 ist ferner mit Befestigungsmitteln 15 zur Montage der Reinigungsvorrichtung, beispielsweise an einer Lackieranlage, ausgestattet. Das Gehäuse 5 kann wahlweise hohlzylinderförmig und bodenseitig offen, als auch als Gefäß 13 mit einem' bodenseitigen Ablauf 14 ausgestaltet sein. Entsprechend kann das verbrauchte Reinigungsmittel über das Gefäß 13 aufgefangen und über einen geeigneten Ablauf 14 entsorgt werden, oder einfach aus dem Gehäuse 5 ablaufen und beispielsweise in bestehende Auswaschungen einer Lackierkabine eingeleitet werden.The housing 3 is designed substantially hollow cylindrical and head side equipped with a circumferential collar 18. The rinsing pipes 1, 2 protrude on opposite sides into the hollow cylindrical housing 5 and have a suitable bend to align the rinsing pipes 3, 4 in the direction of the atomizer receptacle 3, which is attached to the cover 4. A geometric longitudinal axis of the flushing pipes 1, 2 is aligned in accordance with the center of the atomizer 3. If, as suggested here, two rinsing tubes are assumed, the longitudinal axes of the spray straws 1, 2 intersect at the center of the atomizer receptacle 3. The housing 5 is further equipped with fastening means 15 for mounting the cleaning device, for example on a painting installation. The housing 5 may optionally be hollow cylinder-shaped and open on the bottom side, as well as a vessel 13 with a 'bottom-side drain 14 be configured. Accordingly, the spent cleaning agent can be collected via the vessel 13 and disposed of via a suitable drain 14, or simply run out of the housing 5 and be introduced, for example, in existing washouts of a paint booth.

Der Deckel 4 ist kreisförmig ausgestaltet und liegt auf dem Kragen 18 auf. Vorzugsweise kann der Kragen 18 mit einer umlaufenden Dichtung 19 ausgestattet sein, so dass Gehäuse 5 und Deckel 4 gegeneinander abgedichtet sind. Der Deckel 4 weist ferner eine mittige Bohrung auf, wobei die Zerstäuberaufnahme 3 oberhalb der Bohrung des Deckels 4 angebracht ist. Unterhalb der Bohrung bzw. unterhalb der Zerstäuberaufnahme 1 ist ein Trichter 6 vorgesehen, dessen Öffnung grundsätzlich den Spülrohren 1, 2 zugewandt ist. Hierdurch wird eine noch bessere Umlenkung des aus den Spülrohren 1, 2 austretenden Druckluft-Reinigungsmittel-Gemisches sichergestellt.The lid 4 is circular and rests on the collar 18. Preferably, the collar 18 may be provided with a circumferential seal 19 so that the housing 5 and cover 4 are sealed from each other. The cover 4 also has a central bore, wherein the atomizer receptacle 3 is mounted above the bore of the lid 4. Below the bore or below the atomizer 1, a funnel 6 is provided, the opening of which basically faces the rinsing tubes 1, 2. As a result, an even better deflection of emerging from the rinsing pipes 1, 2 compressed air cleaning agent mixture is ensured.

Der Deckel 4 ist über Federelemente 7 mit dem Kragen 18 verbunden, die den Deckel 4 auf den Kragen 18 pressen. Der Deckel 4 und damit die Zerstäuberaufnahme 3 kann entsprechend geringfügig gegenüber dem Gehäuse 5 verschoben werden. Hierdurch ergibt sich eine vorteilhafte Möglichkeit Positionstoleranzen auszugleichen. Dieser mögliche Ausgleich von Positionstoleranzen gewinnt eine besondere Bedeutung im Rahmen einer Integration der Reinigungsvorrichtung in bestehende Lackieranlagen oder bei der Positionierung der Zerstäuber 8 in der Zerstäuberaufnahme durch Roboter. Die Federelemente 7 sind ferner für eine schnell lösbare Verbindung zwischen dem Gehäuse 5 und dem Deckel 4 eingerichtet, so dass neben einer beweglichen Lagerung eine schnelle und einfache Wartung ermöglicht wird. Vorzugsweise eignen sich sogenannte "quicklock" Verschlüsse für eine lösbare Verbindung zwischen Deckel 4 und Gehäuse 5.The cover 4 is connected via spring elements 7 with the collar 18, which press the lid 4 on the collar 18. Der Deckel 4 ist mit dem Deckel 18 verbunden. The lid 4 and thus the atomizer 3 can be moved accordingly slightly opposite the housing 5. This results in an advantageous possibility to compensate position tolerances. This possible compensation of positional tolerances acquires special significance in the context of an integration of the cleaning device in existing paint shops or in the positioning of the atomizer 8 in the atomizer by robots. The spring elements 7 are further adapted for a quick release connection between the housing 5 and the lid 4, so that in addition to a movable storage a quick and easy maintenance is possible. So-called "quicklock" closures are preferably suitable for a detachable connection between cover 4 and housing 5.

Die Zerstäuberaufnahme 3 ist hohlzylinderförmig ausgestaltet und zur Aufnahme eines Zerstäubers, vorzugsweise eines Abschnitts eines Zerstäubers, insbesondere eines Zerstäuberkopfes 8, eingerichtet. Der Zerstäuberkopf 8 kann zumindest abschnittsweise durch die Zerstäuberaufnahme 3 hindurch gesteckt werden. Zur vorteilhaften Halterung des Zerstäuberkopfes 8 ist innerhalb der Zerstäuberaufnahme 1 ein Einsatz 17, vorzugsweise ein Gummieinsatz, vorgesehen.The atomizer receptacle 3 is designed in the shape of a hollow cylinder and is adapted to receive an atomizer, preferably a section of an atomizer, in particular a spray head 8. The atomizer head 8 can be inserted at least in sections through the atomizer receptacle 3. For advantageous retention of the atomizing head 8, an insert 17, preferably a rubber insert, is provided inside the atomiser receptacle 1.

Die Druckluft und das Reinigungsmittel werden den entsprechenden Eingängen der Mischeinrichtung vorzugsweise kontinuierlich und mit einem bestimmten Druckluftdruck und einem Reinigungsmitteldruck zugeführt. Erfindungsgemäß ist nunmehr vorgesehen, dass die Mischeinrichtung 9 dazu eingerichtet ist, die Druckluft mit einer Druckdifferenz gegenüber dem Reinigungsmittel dem Gemischausgang 12 zuzuführen, wobei die Mischeinrichtung 9 ferner dazu eingerichtet ist, die Druckluft mit einem höheren Druck als das Reinigungsmittel dem Gemischausgang 12 zuzuführen. Hierdurch wird ein Vaporisierungseffekt erzielt, d.h. die Oberfläche, sowie das Volumen des Reinigungsmittels wird um ein Vielfaches erhöht, so dass ein maximaler Reinigungserfolg mit niedrigstem Verbrauch an Reinigungsmittel in kürzester Reinigungszeit im Verhältnis zu bekannten Reinigungsmethoden und Reinigungsvorrichtungen . erzielt werden kann. Eine vorgeschlagene Reinigungsvorrichtung ermöglicht eine Einsparung an Druckluft als auch Reinigungsmittel von bis zu 90%. Der Verbrauch an Reinigungsmittel beträgt nur etwa 6 bis 10ml pro Reinigungsvorgang für eine Sprühpistole. Es ist vorteilhafterweise vorgesehen, dass die Mischeinrichtung 9 dazu eingerichtet ist, die Druckluft mit einem um 3 bar höheren Druck als das Reinigungsmittel dem Gemischausgang 12 zuzuführen. Dies kann beispielsweise durch eine Düse zwischen dem Reinigungsmitteleingang und dem Gemischausgang von 0,5 bis 2 mm sichergestellt werden. Als besonders vorteilhafte Drücke haben sich 1 bis 2 bar Spülmitteldruck und entsprechend 4 bis 5 bar Druckluftdruck erwiesen. Die Mischeinrichtung 9 ist ferner dazu eingerichtet, dass kein Reinigungsmittel aus dem Reinigungsmitteleingang 11 in den Drucklufteingang 10 zurückgedrückt werden kann.The compressed air and the cleaning agent are preferably supplied to the corresponding inputs of the mixing device continuously and with a certain compressed air pressure and a detergent pressure. According to the invention it is now provided that the mixing device 9 is adapted to supply the compressed air with a pressure difference compared to the cleaning agent to the mixture outlet 12, wherein the mixing device 9 is further adapted to supply the compressed air at a higher pressure than the cleaning agent to the mixture outlet 12. As a result, a Vaporisierungseffekt is achieved, ie the surface, and the volume of the detergent is increased many times, so that a maximum cleaning success with the lowest consumption of detergent in the shortest cleaning time in relation to known cleaning methods and cleaning devices. can be achieved. A proposed cleaning device allows a saving of compressed air and cleaning agent of up to 90%. The consumption of detergent is only about 6 to 10ml per cleaning process for a spray gun. It is advantageously provided that the mixing device 9 is adapted to supply the compressed air with a 3 bar higher pressure than the detergent to the mixture outlet 12. This can be ensured, for example, by a nozzle between the detergent inlet and the mixture outlet of 0.5 to 2 mm. As particularly advantageous pressures, 1 to 2 bar detergent pressure and correspondingly 4 to 5 bar compressed air pressure have been found. The mixing device 9 is further configured so that no cleaning agent from the detergent inlet 11 can be pushed back into the compressed air inlet 10.

Es ist ferner erfindungsgemäß vorgesehen, dass die Reinigungsvorrichtung gerade nicht mit Düsen bestückt ist, aus denen das Gemisch aus Druckluft und Reinigungsmittel auf die Zerstäuberaufnahme 3 versprüht wird. Vielmehr sind Spülrohre 1, 2 vorgesehen, die einen über die Länge gleichbleibenden Querschnitt aufweisen. Entsprechend müssen keine komplizierten Düsen verwendet werden, die sich während des Betriebes der Reinigungsvorrichtung zusetzen können.It is further provided according to the invention that the cleaning device is currently not equipped with nozzles from which the mixture of compressed air and cleaning agent is sprayed onto the atomizer 3. Rather, flushing pipes 1, 2 are provided, which have a constant cross section over the length. Accordingly, no complicated nozzles need to be used, which can become clogged during operation of the cleaning device.

Vorzugsweise ist die Reinigungsvorrichtung aus VA Edelstahl hergestellt, so dass sich eine einfache Wartung und Eigenreinigung ergibt. Auch zeichnet sich die Reinigungsvorrichtung durch eine kompakte Bauweise für eine hohe Effektivität aus, ist kostengünstig herstellbar und in alle gängigen bestehenden Anlagen integrierbar.Preferably, the cleaning device is made of stainless steel VA, resulting in easy maintenance and self-cleaning.
