PROBLEM TO BE SOLVED: To resolve some problems found in the prior art that members of a shipping mechanism, in particular, a screw conveyor or the like is elongated or retracted to cause each of the members to be damaged or irregular noise to be generated due to friction between the members or powder agents to be ignited by friction heat or firing to be extended due to pouring oil for reducing friction because a hopper part of a dust collector is kept at a high temperature so as not to cause soot dusts or powder agents to become deliquescence state by solidification or condensation of the soot dusts due to cooling down of the soot dusts.SOLUTION: A shipping mechanism 29 comprises a screw conveyor 38 for receiving soot dusts and transferring them to a discharging port 14e1; and an operating part 44 comprised of a first bearing 39 and a second bearing 40 for operably supporting the screw conveyor. Further, there is provided a slide mechanism 42 capable of eliminating a displacement difference caused by thermal extension or shrinkage between a left frame 46 and an operating part 44 between the left frame 46 at a casing 14 to which the first bearing 39 that is at least a part of the operating part 44 is fixed and the operating part 44.SELECTED DRAWING: Figure 9 |
