Abstract

L'invention concerne une installation de pulvérisation d'objets (54) comprenant généralement une cabine de pulvérisation (1) dans laquelle les objets (24) sont enduits d'un matériau de pulvérisation, un dispositif (7, 53) d'amenée d'air qui génère dans la cabine de pulvérisation (1) un écoulement d'air qui capte les excès de pulvérisation dégagés lors de la pulvérisation et les transporte hors de la cabine de pulvérisation (1). Un dispositif de dépôt (15) est disposé dans l'écoulement d'air qui sort de la cabine de pulvérisation (1) et comprend des éléments de dépôt (61) étalés en vrac, sur lesquels les excès de pulvérisation se déposent. Selon l'invention, le dispositif de dépôt (15) et un dispositif d'élimination (25) des éléments de dépôt (61) chargés d'excès de pulvérisation sont regroupés dans un ensemble (50). Les éléments de dépôt (61) sont déplacés en continu ou de manière cadencée dans l'écoulement d'air par un système de transport (60) en circuit fermé. Le système de transport (60) fait en outre passer les éléments de dépôt (61) à travers le dispositif d'élimination (25), de sorte qu'il n'est pas nécessaire d'évacuer les éléments de dépôt (61) ailleurs.
