<P>PROBLEM TO BE SOLVED: To provide a bar screen for dust removal capable of preventing dust from getting in between screen bars without increasing a manufacturing cost. <P>SOLUTION: In this bar screen for dust removal, the screen bars 1 are arranged at equal spaces in the width direction X of a channel, setting the longitudinal direction into the depth direction of flow and the width direction into a flow direction Y. In each screen bar 1, the screen bar 1 on the upstream side of a point located upstream toward the inflow side by a predetermined dimension from an outflow side end part or the outflow side as a starting point is formed as a curved surface, and the inflow side passage of the dust bar screen 1 is made narrower than an outflow side passage to prevent dust from getting in between the screen bars 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
