Abstract

L'invention concerne un dispositif de nettoyage, un système de nettoyage d'un corps sphérique et un procédé de nettoyage d'un corps sphérique, qui permettent un nettoyage uniforme de la surface d'un corps sphérique. Le système de nettoyage d'un corps sphérique est pourvu d'un dispositif de nettoyage pour nettoyer un corps sphérique. Le dispositif de nettoyage selon l'invention comprend un premier élément (11) présentant une première surface (11a) et un second élément (20) présentant une seconde surface (20a) qui est disposée pour faire face à la première surface (11a). La première surface (11a) et la seconde surface (20a) sont des surfaces de retenue pour retenir le corps sphérique entre elles. La première surface (11a) et la seconde surface sont conçues de manière à pouvoir tourner l'une par rapport à l'autre. Le dispositif de nettoyage selon l'invention comprend en outre : une partie de chargement (12) pour recevoir le chargement d'un corps sphérique dans un espace compris entre la première surface (11a) et la seconde surface (20a) ; et une partie d'évacuation (13) pour évacuer le corps sphérique de l'espace susmentionné. La première surface (11a) ou la seconde surface (20a) est pourvue d'un canal hélicoïdal (15) permettant de guider le corps sphérique depuis la partie de chargement (12) jusqu'à la partie d'évacuation (14).
