DUST SOLIDIFICATION DEVICE

To provide a dust solidification device in which a slide resistance of a rod is suppressed.SOLUTION: A dust solidification device comprises: a storage tank 11 for storing dusts; a molding member 121 which is located at a lower part of the storage tank 11, and is provided with a molding hole 122 so that dusts in the storage tank flow therein; and a first rod 123 and a second rod 124 which are driven to perform reciprocating motion for advancing into and retreating from the molding hole, advance into the molding hole to compress the dusts in the molding hole, and face each other. The first rod includes a rod tip part and a rod base part. An axially vertical cross section of the rod tip part of the first rod is so made as to be larger than an axially vertical cross section of the rod base part of the first rod and smaller than an axially vertical cross section of the molding hole.SELECTED DRAWING: Figure 1 【課題】ロッドの摺動抵抗を抑制したダスト固形化装置を提供すること。【解決手段】ダストを貯留する貯留槽１１と、貯留槽１１の下部に配置されて貯留槽内のダストが流入するように成形孔１２２が設けられた成形部材１２１と、成形孔内に進出及び退避して往復運動するように駆動され、成形孔内に進出して成形孔内のダストを圧縮する、互いに対向する第１のロッド１２３及び第２のロッド１２４と、を備え、第１のロッドは、ロッド先端部とロッド基部とを備えるダスト固形化装置とする。第１のロッドのロッド先端部の軸方向垂直断面は、第１のロッドのロッド基部の軸方向垂直断面よりも大きく、且つ成形孔の軸方向垂直断面よりも小さくする。【選択図】図１
