Title (DE) SPRÜHEINRICHTUNG ZUM VERSPRÜHEN VERSCHIEDENER MEDIEN MIT HOHER GESCHWINDIGKEIT
(EN) DEVICE FOR SPRAYING DIFFERENT MEDIA AT GREAT SPEED
(FR) DISPOSITIF DE PULVERISATION A GRANDE VITESSE DE DIFFERENTS AGENTS
Abstract:
(DE) Die Sprüheinrichtung besitzt langgestreckte Mischkammern 9 zum Mischen des auf das Produkt aufzubringenden Mediums mit einem Trägermedium. Das Medium wird über Kapillaren 10 zum gleichmässig verteilten Einspritzen des Mediums in die Mischkammern eingebracht. Über die Länge der Mischkammer verteilt sind Austrittsdüsen 15 angeordnet. Die Mischkammern sind als Nuten in einer Düsenplatte 8 und die Austrittsdüsen als Bohrungen durch den Boden der Nuten ausgebildet.
(EN) Disclosed is a spraying device comprising elongate mixing chambers (9) for mixing the medium that is to be applied to a product with a carrier medium. The medium is introduced into the mixing chambers via capillary tubes (10) in order to inject the medium in an evenly distributed manner. Discharge nozzles (15) are mounted so as to be distributed along the length of the mixing chamber. The mixing chambers are embodied as grooves in a nozzle plate (8) while the discharge nozzles are configured as bores penetrating the bottom of the grooves.
(FR) Dispositif de pulvérisation qui possède des chambres de mélange allongées (9) pour le mélange de l'agent destiné à être appliqué sur un produit avec un milieu porteur. L'agent est introduit dans les chambres de mélange par des tubes capillaires (10) de manière que l'agent soit injecté de façon régulièrement répartie. Des buses de sortie (15) sont situées sur la longueur des chambres de mélange. Lesdites chambres de mélange se présentent sous forme de rainures ménagées dans une plaque (8) à buses, et les buses de sortie sous forme de trous ménagés dans le fond des rainures.
