SELF-CLEANING SYSTEM FOR THE DRY RECOVERY OF MISTS IN AUTOMATIC MACHINES TO SPRAY PAINTS.

摘要

Self-cleaning system for dry recovery of mists in automatic machines for spraying acrylic ultraviolet drying paints, of the type in which the chamber (1) in which the spray guns (P1, P2) work is connected in their upper part of the atmosphere through a circuit for the admission of clean ambient air and in which, inside said chamber (1), on the sides of the self-cleaning conveyor (4) to advance the articles (P) that are to be painted, there are suction inlets (6, 6 '') connected to an external fan (16) of adequate capacity, with the interposition of suitable dry filtering means, characterized in that said suction inlets (6 , 6 '') are inclined transversely downward in the direction of said conveyor (4) and are designed in such a way that filtering grates (7, 7 '') with corrugated profiles can be located transversely thereon, provided n the grilles (7, 7 '') adjacent to each other, in such a way that they cover all the extension of said inlets (6, 6 ''), the longitudinal axes of the undulations being oriented orthogonally to the longitudinal axis of the conveyor ( 4) on which the lower ends of the grilles (7, 7 '') are located, such that the paint retained by said grids (7, 7 ''), which are provided with stepped holes (707, 707 ' ') in a manner suitable for the passage of air, it drips onto said conveyor (4), which carries it away towards the cleaning and recovery means (5) associated with the conveyor (4).
