Abstract: front page image
(EN)Apparatus (10) for filtering particulate material from air and for removing the particulate material collected upon a filter is disclosed. The apparatus (10) includes a housing (12) having an air inlet (32) and an air outlet (38). A hollow longitudinally extending filter (62) is secured within the housing. The filter (62) has an outer surface, an open interior (65), opposite ends (66, 68), and a longitudinal axis extending between the ends. The filter (62) is formed of a porous media. One end (66) of the filter (62) is removably secured relative to the housing (12) so that the longitudinal axis of the filter (62) extends generally vertically. The other end (68) of the filter (62) is closed. A first chamber (42) is defined around the outer surface of the filter (62). The chamber (42) is in communication with the air inlet (32) whereby air moving from the inlet (32) to the outlet (38) passes through the filter (62) into the interior (65) thereof and deposits particulate material on the outer surface of the filter (62). A mechanism (110) is provided for removing the particulate material collected on the outer surface of the filter (62). The mechanism (110) for removing the particulate material includes a device (112) connected to the closed end (68) for rotating the closure plate (72) and the end (68) of the filter (62) attached thereto to twist the filter (62).
(FR)L"appareil (10) est destine a separer une matiere granulaire de l"air et a extraire cette matiere granulaire du filtre. Il comprend un boitier (12) presentant une entree d"air (32) et une sortie d"air (38). Un filtre longitudinal creux (62) est fixe au boitier. Il presente une surface exterieure et un interieur ouvert (65), des extremites opposees (66, 68) et un axe longitudinal s"etendant entre les extremites. Le filtre est forme d"une matiere poreuse. Une des extremites (66) du filtre (62) est fixee de facon amovible au boitier (12) de sorte que l"axe longitudinal du filtre s"etende de facon generale verticalement. L"autre extremite (68) du filtre (62) est fermee. Une premiere chambre (42) est formee autour de la surface exterieure du filtre (62). Elle est en communication avec l"entree d"air (32) afin que l"air en deplacement de l"entree (32) a la sortie (38) passe a travers le filtre (62), a l"interieur (65) de celui-ci et depose la matiere granulaire sur la surface exterieure du filtre (62). Un mecanisme (110) assure l"enlevement de la matiere granulaire fixee sur la surface exterieure du filtre (62). Ce mecanisme (110) comprend un dispositif (112) relie a l"extremite fermee (68) pour tourner la plaque d"obturation (72) et l"extremite (68) du filtre qui lui est rattachee pour tordre le filtre.
