Patent ID: 6969428

Claim:
Self-cleaning system for dry recovery of processing mists in automatic machines for spraying UV-dried acrylic paints or other products which give rise to similar requirements, of the type in which the chamber in which the spray guns operate is connected in its upper part to the atmosphere through a circuit for the admission of clean ambient air and in which, inside said chamber, at the sides of the self-cleaning conveyor for advancing the articles to be painted, there are suction intakes connected to an external fan of suitable capacity, with the interposition of suitable dry filter means, characterized in that said suction intakes are inclined transversely downwards towards said conveyor and are designed in such a way that filter grids with corrugated profiles can be positioned transversely on them, the grids being adjacent to each other, in such a way as to cover the whole extension of said intakes, the longitudinal axes of the corrugations being orientated orthogonally to the longitudinal axis of the conveyor on which the lower ends of the grids are positioned, in such a way that the paint retained by said grids, which are provided with suitably staggered holes for the passage of air, drips onto said conveyor which carries it away towards a cleaning and recovery means associated with the conveyor.
