Title (EN) DEVICE FOR DUST-FREE ABRASIVE BLASTING, PAINTING AND HIGH-PRESSURE WASHING OF SURFACES
(FR) APPAREIL DE GRENAILLAGE SANS POUSSIERE, DE PEINTURE ET DE LAVAGE DE SURFACES SOUS HAUTE PRESSION
Abstract:
(EN) The invention relates to an improved blast apparatus, in which the blast nozzle (16) during transport in the direction of the main cylinder (10) is brought to execute a torsional movement in the plane of the nozzle, cutting across the working direction of the main cylinder, whereby the jet of blast medium will perform a sweeping motion laterally. Additionally, the jet of blast medium can be brought to hit the surface in an oblique angle so that the jet is constantly directed slightly against the working direction of the main cylinder. Furthermore, the blast nozzle can be enclosed in a protective cover (20), the opening (21) of which can be pressed against the object under work. Hereby it is possible to carry out other types of surface treatment, for example, washing and painting, in the immediate vicinity of the blast automaton. If whished, the blast apparatus can be provided with nozzles for washing and painting.
(FR) L'invention concerne un appareil amélioré de grenaillage, dans lequel la buse de projection (16), durant le transport dans la direction du cylindre principal (10), est amenée à effectuer un mouvement de torsion dans le plan de la buse, transversalement par rapport à la direction de travail du cylindre principal, grâce à quoi le jet de milieu projeté effectue un mouvement de balayage latéral. De plus, le jet de milieu de grenaillage peut être dirigé pour frapper la surface à un angle oblique pour que le jet soit constamment dirigé légèrement contre la direction de travail du cylindre principal. En outre, la buse de projection peut être enfermée par une enceinte de protection (20), dont l'ouverture (21) peut être pressée contre l'objet en cours de traitement. Il est ainsi possible d'effectuer d'autres types de traitements de surface, par exemple de lavage et de peinture, au voisinage immédiat de l'automate de pulvérisation. Lorsque cela est souhaité, l'appareil de pulvérisation peut être pourvu de buses permettant des opérations de peinture et de lavage.
