Abstract

L'invention concerne un dispositif de filtration comportant un récipient de filtration, à partir de l'intérieur duquel de l'air brut chargé de poussières s'écoule vers l'extérieur après avoir été purifié, en passant par les cartouches-filtres insérées dans des ouvertures ménagées dans le couvercle du récipient. Ce dispositif comprend en outre un dispositif d'épuration de l'air comprimé qui comporte un réservoir d'air comprimé et des buses d'air comprimé qui y sont raccordées, au-dessus des ouvertures de filtration. Le réservoir d'air comprimé constitue avec les buses d'air comprimé et les éléments de raccordement, une unité rigide qui est maintenue pivotante et/ou amovible sur le réservoir de filtration, au moyen d'un dispositif de fixation. Ce procédé permet de sortir de manière aisée et rapide le dispositif d'air comprimé de la zone où les cartouches-filtres ont été insérées et d'enlever ou d'insérer facilement ces dernières. Cette invention présente en outre l'avantage d'avoir une structure modulaire qui permet aux installations de filtration en place d'être adaptées ou modernisées.
