PROBLEM TO BE SOLVED: To provide a dust remover having simply-structured coarse aperture parts for capturing relatively large dust and simply-structured fine aperture parts for capturing fine dust and capable of effectively raking up the duct captured by the aperture parts.SOLUTION: In a dust remover installed in a water conduit, a flat sectional shape of each of bars 2A is shaped in a convex 13 of which front part is an apex 11 and of which back part is a wide part 12 with a cross sectional area gradually increased from the apex 11. The dust remover comprises: a screen 2 in which bars 2A are juxtaposed with the apex 11 of each bar 2A arranged on the upstream side of the water conduit and the wide part 12 arranged on the downstream side, so that an interval between the apexes 11 of the adjacent bars 2A becomes a coarse aperture part 10A, and an interval between the ends of the wide parts 12 becomes a fine aperture part 10B; and a rake 3 in which a flat sectional shape of each of comb teeth 9 is shaped in a convex 19 formed to be along the shapes of the coarse and fine aperture parts 10A, 10B of the bar 2A. |
