Description

Die Erfindung betrifft eine Glasurspritzkabine mit Außenwänden aus Metall oder wasser- und gasdichtem Kunststoff.The invention relates to a glaze spray booth with outer walls made of metal or water and gas-tight plastic.

Bei den derzeitigen und herkömmlichen Ausführungen von Spritzkabinen bestehen die Wände aus Metall, z.B. Nirosta, oder aus Kunststoff. Die bekannten Spritzkabinen haben den Nachteil, daß der Aufwand für ihre Reinigung ziemlich hoch ist. Bei Farbwechsel oder bei den notwendigen Zwischenreinigungen müssen die Glasurreste von den Kabinenwänden abgeschert, die Glasurreste aus der Kabine geschaufelt und die Kabine anschließend mit einem Hochdruckreiniger gereinigt werden. Die Reinigung einer herkömmlichen Spritzkabine nimmt auf diese Weise etwa 1 Stunde in Anspruch. Durch das notwendige oftmalige Reinigen pro Tag entstehen sehr hohe Reinigungskosten, und es ergibt sich eine geringe Nutzungsdauer.In the current and conventional designs of spray booths, the walls are made of metal, e.g. Nirosta, or made of plastic. The known spray booths have the disadvantage that the cost of cleaning them is quite high. When changing colors or during the necessary intermediate cleaning, the glaze residues must be sheared off the cabin walls, the glaze residues shoveled out of the cabin and the cabin then cleaned with a high-pressure cleaner. This way, cleaning a conventional spray booth takes about 1 hour. The necessary frequent cleaning per day results in very high cleaning costs and there is a short service life.

Ziel der Erfindung ist die Bereitstellung einer Glasurspritzkabine, bei der die angeführten Nachteile beseitigt sind, d.h. daß die Kosten der Reinigung und der Zeitaufwand hiefür verhältnismäßig gering sind.The aim of the invention is to provide a glaze spray booth in which the disadvantages mentioned are eliminated, i.e. that the cost of cleaning and the time required for it are relatively low.

Dieses Ziel wird mit einer Spritzkabine mit Außenwänden aus Metall oder wasser- und gasdichtem Kunststoff erreicht,die erfindungsgemäß eine Auskleidung aus Kunststoff mit offener Porenstruktur aufweist, die mit Anschlüssen für Wasser und für Druckluft in Verbindung steht.This goal is achieved with a spray booth with outer walls made of metal or water- and gas-tight plastic, which according to the invention has a plastic lining with an open pore structure, which is connected to connections for water and for compressed air.

Die komplette Innenauskleidung der Spritzkabine ist aus Kunststoff, beispielsweise auf Acrylharzbasis mit offener Porenstruktur, gefertigt. Die Innenwandteile aus Kunststoff mit offener Porenstruktur sind mit Anschlüssen für Wasser und Luft ausgestattet.The complete interior lining of the spray booth is made of plastic, for example based on acrylic resin with an open pore structure. The inner wall parts made of plastic with an open pore structure are equipped with connections for water and air.

Nach einem weiteren Merkmal der Erfindung sind in der Auskleidung längs- und/oder querverlaufende Leitungen mit über ihre Länge gleichmäßig verteilten Austrittsöffnungen zur Zufuhr von Wasser und Druckluft angeordnet. Erfindungsgemäß sind die den Außenwänden zugewandten Seiten der Auskleidung mit Bohrungen versehen, die über die gesamte Auskleidungsfläche gleichmäßig verteilt sind, wobei die Bohrungen vorzugsweise eine Tiefe haben, die bis zu einem Zentimeter an die Innenoberfläche der Auskleidung heranreicht. Auf diese Weise wird erreicht, daß der gesamten Ausklediung gleichmäßig Wasser bzw. Druckluft zugeführt werden kann.According to a further feature of the invention, longitudinal and / or transverse lines are arranged in the lining with outlet openings uniformly distributed over their length for the supply of water and compressed air. According to the invention, the sides of the lining facing the outer walls are provided with bores which are evenly distributed over the entire lining surface, the bores preferably having a depth which extends up to one centimeter to the inner surface of the lining. In this way it is achieved that the entire discharge can be supplied with water or compressed air evenly.

Zwecks Reinigung der Kabine wird zunächst etwa eine halbe Minute Wasser in die Auskleidung aus Kunststoff mit offener Porenstruktur eingeleitet, wobei sich der Kunststoff wie ein Schwamm auffüllt und teilweise sich die Glasur an den Wänden zu lösen beginnt. Danach wird Luft in die Auskleidung aus dem Kunststoff mit offener Porenstruktur gepreßt. Das Wasser tritt vermischt mit der Druckluft aus der Auskleidung aus dem Kunststoff mit offener Porenstruktur aus. Die gesamte Glasur an den Wänden fließt in ein unterhalb gelegenes Auffangbecken ab. Dieser Vorgang kann z.B. etwa jede halbe Stunde vorgenommen werden, wobei er vollautomatisch über Ventile gesteuert werden kann. Die Reinigung der erfindungsgemäßen Glasurspritzkabine ist also wesentlich einfacher und viel weniger aufwendig als die Reinigung der bekannten Spritzkabinen. Zudem ergibt sich noch der weitere Vorteil, daß die gesamte Glasur, die von der Kabine in das Auffangbecken läuft, wieder verwertet werden kann, sodaß nichts verloren geht. Auf diese Weise sind Entsorgungsprobleme vermieden und die Umwelt wird geschont.For cleaning the cabin, about half a minute of water is first introduced into the plastic lining with an open pore structure, whereby the plastic fills up like a sponge and the glaze on the walls partially begins to dissolve. Then air is pressed into the plastic lining with an open pore structure. The water emerges mixed with the compressed air from the lining made of plastic with an open pore structure. The entire glaze on the walls flows into a collecting basin below. This process can e.g. about every half hour, whereby it can be controlled fully automatically via valves. The cleaning of the glaze spray booth according to the invention is thus much easier and much less complex than the cleaning of the known spray booths. In addition, there is the further advantage that the entire glaze that runs from the cabin into the catch basin can be recycled so that nothing is lost. In this way, disposal problems are avoided and the environment is protected.

In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawings, an embodiment of the invention is shown.
