Die Erfindung betrifft eine Vorrichtung zum wasserdampfunterstützten Spritzen von Beschichtungsmaterial gemäß dem Oberbegriff von Patentanspruch 1. Die Erfindung bezieht sich auch auf ein Verfahren zum Beschichten von Substraten mit einem Beschichtungsmaterial gemäß dem Oberbegriff von Patentanspruch 7.The The invention relates to a device for steam-assisted spraying of coating material according to the preamble of claim 1. The invention also relates to a method for coating substrates with a coating material according to the preamble of claim 7.

Weitere Angaben zur Ausgestaltung der Spritzvorrichtung sowie zur Dampferzeugung sind dieser Schrift nicht zu entnehmen.Further Information on the design of the spray device and steam generation are not apparent from this document.
Vorrichtungen zum wasserdampfunterstützten Spritzen von Beschichtungsmaterial haben den Nachteil, dass der Wasserdampf im Spritzapparat kondensiert und dort zu einer nachteiligen Wasseransammlung führt, wodurch insbesondere das Sprühbild beeinträchtigt wird.devices for water vapor assisted Spraying of coating material have the disadvantage that the Water vapor condenses in the spray gun and there to an adverse water accumulation leads, whereby in particular the spray pattern impaired becomes.
Aufgabe der Erfindung ist es, eine Vorrichtung und ein Verfahren zum wasserdampfunterstützten Spritzen von Beschichtungsmaterial anzugeben, bei der kein kondensiertes Wasser anfällt.task The invention is an apparatus and a method for steam-assisted spraying of coating material in which no condensed Water is generated.
Diese Aufgabe wird dadurch gelöst, dass dem Dampferzeuger ein Dampferhitzer nachgeschaltet ist, der überhitzten Dampf erzeugt. Der Dampferhitzer erhitzt den Dampf vorzugsweise auf eine Temperatur von 200°C bis 260°C, insbesondere auf 220°C bis 250°C. Es hat sich herausgestellt, dass durch die Verwendung von überhitztem Dampf selbst bei dem Temperaturabfall an der oder den Austrittsdüse/n des Spritzapparates kein Kondenswasser anfällt. Dadurch wird gewährleistet, dass das Sprühbild nicht beeinträchtigt wird.These Task is solved by that the steam generator is followed by a steam heater, which overheated Steam generated. The steam heater preferably heats the steam to a temperature of 200 ° C up to 260 ° C, especially at 220 ° C up to 250 ° C. It has been proven that through the use of overheated Steam even at the temperature drop at the outlet nozzle (s) Sprayer no condensation occurs. This will ensure that the spray picture is not impaired becomes.
Vorzugsweise weist der Spritzapparat eine Dampfringdüse und mindestens zwei gegenüberliegend angeordnete Dampfflachstrahldüsen auf, wobei die Düsen über Dampfmengenregler an den Dampferhitzer angeschlossen sind.Preferably the spray gun has a steam ring nozzle and at least two opposite arranged steam jet nozzles on, with the nozzles via steam flow regulator connected to the steam heater.
Die Dampfringdüse umgibt vorzugsweise die Materialaustrittsdüse. Der durch die Dampfringdüse austretende überhitzte Wasserdampf dient der Zerstäubung des Beschichtungsmaterials, wobei ein im wesentlichen kreisförmiger Beschichtungsstrahl (Rundstrahl) erzeugt wird.The Dampfringdüse preferably surrounds the material outlet nozzle. The superheated by the steam ring nozzle exiting Steam is used for atomization of the coating material, wherein a substantially circular coating jet (round jet) is produced.
Über die Dampfflachstrahldüsen wird ebenfalls überhitzter Wasserdampf seitlich auf den Rundstrahl gerichtet, so dass aus dem Rundstrahl ein Flachstrahl erzeugt werden kann.About the Steam fan nozzles is also overheated Steam is directed sideways on the round jet, so that from the Round jet a flat jet can be generated.
Da sowohl die Dampfringdüse als auch die beiden Dampfflachstrahldüsen mit überhitztem Wasserdampf beaufschlagt werden, ist nur ein Dampferzeuger und ein Dampferhitzer erforderlich. Über die Dampfmengenregler kann der Beschichtungsstrahl auf die gewünschte Strahlform eingestellt werden. Je größer die Dampfmenge gewählt wird, die durch die Dampfflachstrahldüsen austritt, desto flacher wird der Beschichtungsstrahl.There both the steam ring nozzle as well as the two steam jet nozzles with superheated steam applied only one steam generator and one steamer heater are required. About the steam quantity regulator the coating jet can be adjusted to the desired beam shape become. The bigger the Steam quantity selected As it passes through the steam jet nozzles, the flatter becomes the coating jet.
Vorzugsweise werden die beiden Dampfflachstrahldüsen über einen gemeinsamen Dampfmengenregler an den Dampferhitzer angeschlossen. Die Versorgung über einen gemeinsamen Dampfmengenregler gewährleistet, dass die Dampfmenge, die aus den beiden Dampfflachstrahldüsen austritt, gleich groß ist, so dass ein symmetrischer Flachstrahl erzeugt werden kann.Preferably The two steam jet nozzles are via a common steam flow regulator connected to the steam heater. The supply over one common steam regulator ensures that the amount of steam that from the two steam jet nozzles exit, is equal, so that a symmetrical flat jet can be generated.
Vorzugsweise sind die Dampfflachstrahldüsen in gegenüberliegenden Düsenhörnern angeordnet.Preferably are the vapor jet nozzles in opposite Arranged nozzle horns.
Es hat sich gezeigt, dass durch die Verwendung von überhitztem Wasserdampf weder in der Dampfringdüse noch an den Dampfflachstrahldüsen eine Kondensatbildung auftritt, die das gewünschte Sprühbild beeinflussen könnte.It It has been shown that by using superheated steam neither in the steam ring nozzle still at the steam jet nozzles one Condensation occurs that could affect the desired spray pattern.
Um eine vorzeitige Abkühlung des Wasserdampfes und somit eine Kondensatbildung innerhalb des Spritzapparates zu verhindern, ist vorzugsweise vorgesehen, dass die materialführenden Bauteile des Spritzapparates aus einem wärmeisolierenden Material bestehen. Hierfür kommen insbesondere Kunststoffe oder Keramiken in Frage.Around a premature cooling the water vapor and thus a condensation within the To prevent spray guns, it is preferably provided that the material leading Components of the spray gun consist of a heat-insulating material. Therefor In particular, plastics or ceramics come into question.
Vorzugsweise bestehen die dampfführenden Bauteile des Spritzapparates aus einem wärmeleitenden Material, wie z. B. Metall. Hierfür kommen insbesondere Stahl oder Edelstahl in Frage. Die Materialpaarung von Metall und wärmeisolierenden Materialien bewirkt einerseits eine günstige Wärmeisolation innerhalb des Spritzapparates, andererseits wirkt die wärmespeichernde Eigenschaft des Metalls optimal auf die Dampfqualität ein.Preferably exist the steam-carrying components of the spray gun made of a thermally conductive Material, such. Metal. This is especially steel or stainless steel in question. The material combination of metal and heat insulating On the one hand, materials cause a favorable heat insulation within the Spritzapparates, on the other hand affects the heat-storing property of the metal optimally on the steam quality.
Das Verfahren zum Beschichten von Substraten mit einem Beschichtungsmaterial, wobei das Beschichtungsmaterial durch Unterstützung von Wasserdampf aufgespritzt wird, ist dadurch gekennzeichnet, dass überhitzter Wasserdampf verwendet wird.The method for coating Subst Advised with a coating material, wherein the coating material is sprayed by supporting steam, is characterized in that superheated steam is used.
Vorzugsweise wird Wasserdampf mit einer Temperatur von 200°C bis 260°C, insbesondere von 220°C bis 250°C, verwendet.Preferably steam with a temperature of 200 ° C to 260 ° C, in particular from 220 ° C to 250 ° C, is used.
