Title (EN) HOOD FOR SUCKING-UP FINE PARTICLES, AND A DEVICE INTENDED FOR THE LASER ABLATION OF A SURFACE LAYER OF A WALL AND INCLUDING SUCH A HOOD
(FR) AVALOIR D'ASPIRATION DE PARTICULES FINES ET DISPOSITIF D'ABLATION LASER D'UNE COUCHE SUPERFICIELLE D'UNE PAROI COMPRENANT UN TEL AVALOIR
Abstract:
(EN) The invention relates to a hood for sucking-up fine particles, including: a mouth (3b) intended to be placed close to a wall (2), a base (3a) having a window (3) through which a laser beam (6) can pass, an intermediate portion (5a) between the mouth (3b) and the base (3a), and a suction outlet (5) disposed on the intermediate portion (5a) of the hood (1) and designed to suck-up fine particles. The hood is characterized in that it comprises at least one air intake (110) positioned near the base (3a) and, during operation, capable of creating a stream of air at the base (3a) of the hood (1) so as to prevent fine particles from being deposited on the window (3).
(FR) L'invention concerne un avaloir d'aspiration de particules fines comprenant : une embouchure (3b) destinée à être disposée à proximité d'une paroi (2); une base (3a) comportant un hublot (3) apte à laisser passer un faisceau laser (6); une partie intermédiaire (5a) entre l'embouchure (3b) et la base (3a); une sortie d'aspiration (5) disposée sur la partie intermédiaire (5a) de l'avaloir (1) destinée à aspirer les particules fines; l'avaloir est caractérisé en ce qu'il comprend au moins une entrée (110) d'air disposée au niveau de la base (3a), apte à créer, en fonctionnement, un courant d'air au niveau de la base (3a) de l'avaloir (1) empêchant le dépôt de particules fines sur le hublot (3).
