PROBLEM TO BE SOLVED: To provide a dust collector including net frames capable of reducing deformation amount by rotating force in a cross sectional direction of the net frames even if water flow resistance of the net frames for collecting dust rises.SOLUTION: In a dust collector 10, a plurality of net frames 30 for collecting dust are mounted in an endless link chain 22, and the link chain is circularly moved in a direction crossing a flow direction of a fluid by a sprocket wheel. The dust collector includes: a second bar screen 50 mounting a plurality of second flat bars 52 at equal intervals so as to extend in a vertical direction of the net frames 30; and a first bar screen 40 mounting a plurality of first flat bars 42 at equal intervals so as to extend in the vertical direction of the net frames 30. The first flat bar 42 includes a body 42a and a pair of legs 42b extending in a crossing direction from both ends of the body. The second flat bar is formed into a rectangular shape in a side cross-sectional view, and an upstream side end of the second flat bar and a downstream side end of the body are formed on the same plane.SELECTED DRAWING: Figure 1 |
