Title
(EN) IMPROVED DUST/PARTICLE COLLECTING ARRANGEMENT FOR CYCLONE SEPARATORS
(FR) APPAREIL COLLECTEUR DE POUSSIERE ET DE PARTICULES POUR SEPARATEURS CYCLONE
Abstract
(EN) Apparatus is described for separating particulate material from an airstream established by suction. The apparatus comprises a primary separation chamber (12) in which particles are separated from the airstream therein by centrifugal force, a main particle collecting region (14) into which the particles separated by the primary separation can fall under gravity, and a secondary separation chamber (90) downstream of the primary chamber (12), to which air and particles not separated in the first chamber, pass. An air outlet in the secondary chamber allows air substantially free of particles to exit. An intermediate particle collecting region (22) is associated with the secondary chamber, in which particles collect after separation by centrifugal force from the air flowing through the secondary chamber (90). A valve (41) is provided between the intermediate particle collecting (22) region and a second particle collecting region (14), which is closed while air flows through the apparatus but which is opened when airflow ceases, to allow particles in the intermediate region (22) to pass into the second region (14).
(FR) L'invention concerne un appareil servant à séparer des particules d'un filet d'air établi par aspiration. Cet appareil comprend une chambre de séparation primaire (12) dans laquelle les particules sont séparées du filet d'air par centrifugation, une zone principale collectrice de particules (14) dans laquelle les particules séparées au moment de la première séparation primaire peuvent être entraînées par gravité et une chambre de séparation secondaire (90) située en aval de la chambre primaire (12), dans laquelle passent l'air et les particules qui n'ont pas été séparées dans la première chambre. Dans la chambre secondaire, une sortie d'air laisse passer de l'air sensiblement dépourvu de particules. Après leur séparation par centrifugation de l'air s'écoulant dans la chambre secondaire (90), les particules sont collectées dans une zone intermédiaire collectrice de particules (22) qui est associée à la chambre secondaire. Une soupape (41) disposée entre la zone intermédiaire collectrice de particules (22) et une seconde zone collectrice de particules (14) reste fermée pendant que l'air s'écoule dans l'appareil et s'ouvre lorsque l'écoulement prend fin, afin de permettre le passage dans la seconde zone (14) des particules se trouvant dans la zone intermédiaire (22).
