BeschreibungDescription

Vorrichtung zum Reinigen von Düsen bei der pneumatisch - hydraulischen Zerstäubung. Device for cleaning nozzles during pneumatic-hydraulic atomization.

Vorrichtungen zum Reinigen von Düsen bei der hydraulischen Zerstäubung weisen im allgemeinen einen, um seine Längsachse drehbaren Zylinder mit einer, mit ihrer Längachse rechtwinklig zur Längsachse des Zylinders montierten, Düse auf. Dieser Zylinder ist durch einen halbmondförmigen Abdichtzylinder abgedichtet.Devices for cleaning nozzles in hydraulic atomization generally have a cylinder that can rotate about its longitudinal axis and has a nozzle mounted with its longitudinal axis perpendicular to the longitudinal axis of the cylinder. This cylinder is sealed by a crescent-shaped sealing cylinder.

Diese Vorrichtungen weisen oft auch eine Halbkugel auf, die in einer Achse mit einer Düse ausgestattet ist und, rechtwinklig zu dieser Achse, um 180° gedreht werden kann.These devices often also have a hemisphere equipped with a nozzle on one axis and which can be rotated by 180° at right angles to this axis.

Ist nun eine Düse durch grobes Pigment, Füllstoff u.s.w., welche nicht durch die Düsenbohrung passt, verstopft, wird durch Drehen um 180° der jeweilige verstopfende Partikel durch Betätigen der Spritzpistole vom Spritzdruck aus der Düse heraus geblasen und somit die Verstopfung behoben. Durch Zurückdrehen um 180° in die Spritzposition wird der normale Betriebszustand wieder hergestellt.If a nozzle is now clogged by coarse pigment, filler, etc. that does not fit through the nozzle bore, the clogging particle is blown out of the nozzle by the spray pressure by operating the spray gun by turning it 180°, thus removing the blockage. The normal operating state is restored by turning it back 180° to the spray position.

Der in Schutzanspruch 1 dargestellten Erfindung liegt das Problem zugrunde, daß bei der pneumatisch - hydraulischen Zerstäubung die Düse in einer Aufnahme festmontiert ist und bei einer Düsenverstopfung sehr aufwendig demontiert und mit Düsennadeln und Druckluft gereinigt und danach wieder montiert werden muß. Diese Aktion ist immer sehr zeitaufwendig und damit kostenintensiv; ausserdem wird die Düse durch die Düsennadel sehr oft an den Strahlformkanten beschädigt, wodurch sie unbrauchbar werden.The invention presented in claim 1 is based on the problem that in pneumatic-hydraulic atomization the nozzle is permanently mounted in a holder and if the nozzle becomes clogged it has to be dismantled, cleaned with nozzle needles and compressed air and then reassembled, which is very laborious. This process is always very time-consuming and therefore costly; in addition, the nozzle is very often damaged by the nozzle needle at the jet shape edges, making them unusable.

Mit der Erfindung nach Anspruch 1 wird erreicht, daß bei der pneumatisch - hydraulischen Zerstäubung eine Düse, wenn sie verstopft ist, durch einfaches Drehen um 180°The invention according to claim 1 ensures that in the pneumatic-hydraulic atomization, if a nozzle is clogged, it can be emptied by simply turning it by 180°.

quer zu ihrer Längsachse, durch Be*fa*t*gen der Pistole, von dieser Verunreinigung freigespült wird.transversely to its longitudinal axis, by gripping the gun, it is rinsed free of this contamination.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist nach Schutzrechtsanspruch 6 gegeben. Hier ist es möglich eine ausschließlich für die hydraulische Zerstäubung eingerichtete Pistole, oder ein Sprühgerät, für die pneumatisch - hydraulische Zerstäubung nachzurüsten.A further advantageous embodiment of the invention is given in claim 6. Here it is possible to retrofit a gun designed exclusively for hydraulic atomization or a spray device for pneumatic-hydraulic atomization.

Device according to protection claims 1-2, characterized in that the hydraulically atomized spray jet can be supplied with atomizing air on both the broad side and the narrow side on both sides directly or indirectly through the air nozzles (2) and (3). 4. Vorrichtung nach Schutzanspruch 1 - 3 dadurch gekennzeichnet, daß die Düse zum Wenden um 180° in einem abgedichteten Zylinder (4) montiert ist.4. Device according to protection claims 1 - 3, characterized in that the nozzle is mounted in a sealed cylinder (4) for turning by 180°. 5. Vorrichtung nach Schutzanspruch 1 - 3 dadurch gekennzeichnet, daß die Düse zum Wenden um 180° in einer abgedichteten Hohlkugel montiert ist.5. Device according to protection claims 1 - 3, characterized in that the nozzle is mounted in a sealed hollow sphere for turning by 180°. 6. Vorrichtung nach Schutzrecht 1 - 5 dadurch gekennzeichnet, daß sie mit einer gesonderten Sprühluftzuführieitung, mit Drosselschrauben und Steuerventilen ausgerüstet
sein kann, die es ermöglichen eine Spritzpistole, die ausschließlich für die reine hydraulische Zerstäubung ausgerüstet ist, nachträglich für die kombinierte hydraulisch - pneumatische Zerstäubung auszurüsten.6. Device according to patent 1 - 5, characterized in that it is equipped with a separate spray air supply line, with throttle screws and control valves
which make it possible to subsequently equip a spray gun which is exclusively equipped for pure hydraulic atomization for combined hydraulic-pneumatic atomization.
