Abstract

La présente invention concerne une unité cyclonique et un dispositif de nettoyage de surface de route équipé de ladite unité. L'unité cyclonique comprend : un premier tuyau unitaire qui a un premier espace d'écoulement formé à l'intérieur de celui-ci et une pluralité d'entrées formées sur la surface circonférentielle externe de celui-ci de telle sorte que l'air soufflé de façon forcée à partir d'une unité d'aspiration peut entrer dans le premier espace d'écoulement ; un second tuyau d'unité qui est disposé au-dessous du premier tuyau d'unité et qui a un second espace d'écoulement formé à l'intérieur de celui-ci de façon à communiquer avec le premier espace d'écoulement, le second espace d'écoulement étant formé de telle sorte que le diamètre interne diminue progressivement vers le fond ; et des parties de guidage d'écoulement qui sont installées dans les entrées afin de guider l'air entrant dans le premier tuyau d'unité de telle sorte que l'air s'écoulant dans le premier espace d'écoulement s'écoule dans une trajectoire en spirale le long de la paroi interne du premier tuyau d'unité, et des substances étrangères peuvent être séparées de celui-ci. L'unité cyclonique et le dispositif de nettoyage de surface de route équipé de celle-ci selon la présente invention amènent l'air aspiré à partir de l'unité d'aspiration à s'écouler le long d'une trajectoire en spirale et à filtrer des substances étrangères à partir de celui-ci, et ont ainsi l'avantage de pouvoir fournir une efficacité de nettoyage relativement élevée même pendant une longue période d'utilisation.
