Abstract

La présente invention concerne : une unité de nettoyage de filtre de collecte de poussière pour éliminer directement la matière étrangère de la surface d'un filtre de collecte de poussière par pulvérisation d'air comprimé sur la surface du filtre de collecte de poussière à laquelle la matière étrangère est fixée ; un collecteur de poussière le comprenant ; et un procédé de commande du collecteur de poussière. À cet effet, dans un collecteur de poussière comprenant un corps de trémie creux, une paroi de séparation divisant l'espace intérieur du corps de trémie en un espace d'admission et un espace pur, et un filtre de collecte de poussière pour filtrer une matière étrangère de l'air d'admission introduit dans l'espace d'admission lorsque l'air d'admission introduit dans l'espace d'admission passe à travers celui-ci et se déplace dans l'espace pur, une unité de nettoyage de filtre de collecte de poussière retire la matière étrangère fixée à la surface du filtre de collecte de poussière à partir du filtre de collecte de poussière. L'unité de nettoyage de filtre de collecte de poussière selon la présente invention pulvérise la surface du filtre de collecte de poussière avec de l'air comprimé tout en se déplaçant le long du filtre de collecte de poussière dans l'espace d'admission.
