Abstract
(EN)
This filtration device (10) is provided with: a filtration tank (12); a first drum filter (30), both ends of which are supported; and a second drum filter (40) which is a cantilever. A first end (30a) of the first drum filter (30) is supported on a first side wall (12a) of the filtration tank (12). A second end (30b) of the first drum filter (30) is supported on a second side wall (12b). An end (40a) on a supported side of the second drum filter (40) is supported on the first side wall (12a). A communication part (51) is formed between the second side wall (12b) and an end (40b) on a non-supported side of the second drum filter (40). A first spray part (60) sprays a liquid toward an outer circumferential surface (30c) of the first drum filter (30). A second spray part (70) is disposed in the vicinity of the second drum filter (40) and sprays a liquid toward an outer circumferential surface (40c) of the second drum filter 40.

Ce dispositif de filtration (10) comprend : un réservoir de filtration (12); un premier filtre à tambour (30) dont les deux extrémités sont supportées; et un second filtre à tambour (40) qui est un porte-à-faux. Une première extrémité (30a) du premier filtre à tambour (30) est supportée sur une première paroi latérale (12a) du réservoir de filtration (12). Une seconde extrémité (30b) du premier filtre à tambour (30) est supportée sur une seconde paroi latérale (12b). Une extrémité (40a) sur un côté supporté du second filtre à tambour (40) est supportée sur la première paroi latérale (12a). Une partie de communication (51) est formée entre la seconde paroi latérale (12b) et une extrémité (40b) sur un côté non supporté du second filtre à tambour (40). Une première partie de pulvérisation (60) pulvérise un liquide vers une surface circonférentielle externe (30c) du premier filtre à tambour (30). Une seconde partie de pulvérisation (70) est disposée à proximité du second filtre à tambour (40) et pulvérise un liquide vers une surface circonférentielle externe (40c) du second filtre à tambour.
