Abstract

L’invention concerne un système avec un appareil de projection de poudre (1) et un élément rapporté (2) servant à nettoyer l’appareil de projection de poudre (1), dans lequel l’appareil de projection de poudre (1) présente : une chambre (3) pour un milieu pulvérulent, un corps principal (4) avec une zone d’entrée de milieu (5) servant à faire entrer un milieu et avec une zone de sortie de milieu (6) servant à faire sortir le milieu pulvérulent, dans lequel le corps principal (4) présente un premier conduit de milieu (7), qui est disposé de manière à mener depuis une zone d’évacuation (8) de la chambre (3) vers la zone de sortie de milieu (6), ainsi qu’un deuxième conduit de milieu (9), qui est disposé de manière à mener depuis la zone d’entrée de milieu (5) vers la zone de sortie de milieu (6). L’élément rapporté (2) est adapté pour être relié à la zone de sortie de milieu (6) et est configuré pour relier le deuxième conduit de milieu (9) au premier conduit de milieu (7) de manière conductrice pour un fluide de nettoyage de telle sorte que le fluide de nettoyage affluant dans le deuxième conduit de milieu (9) en passant par la zone d’entrée de milieu (5) s’écoule vers l’élément rapporté (2) puis, de là, vers la zone d’évacuation (8) de la chambre (3) par le premier conduit de milieu (7). Figure pour l’abrégé : Fig. 1The invention relates to a system with a powder spray device (1) and an insert (2) for cleaning the powder spray device (1), in which the powder spray device (1) has : a chamber (3) for a powder medium, a main body (4) with a medium inlet area (5) for entering a medium and with a medium outlet area (6) for exiting the powder medium, in which the main body (4) has a first medium conduit (7), which is arranged to lead from a discharge zone (8) of the chamber (3) to the medium outlet zone (6), as well as a second medium conduit (9), which is arranged to lead from the medium inlet zone (5) to the medium outlet zone (6). The insert (2) is adapted to be connected to the medium outlet zone (6) and is configured to connect the second medium conduit (9) to the first medium conduit (7) in a conductive manner for a fluid of cleaning fluid in such a way that the cleaning fluid flowing into the second medium conduit (9) via the medium inlet zone (5) flows to the insert (2) and then from there to the evacuation zone (8) of the chamber (3) via the first medium duct (7). Figure for abstract: Fig. 1
