REMOVAL DEVICE OF CEMENT POWDER DUST, CEMENT KNEADING METHOD, AND CUTTING METHOD OF CEMENT HARDENED BODY

PROBLEM TO BE SOLVED: To provide a removal device capable of efficiently and stably removing powder dust of cement for a long period of time so that an amount of the powder dust is decreased.SOLUTION: A removal device 1 includes: a suction mechanism comprising a suction tube 40, a suction machine 20, and an air supply pipe 30; and a dust collection container 4. Inside the dust collection container 4, a dust removal fluid 7 is stored. In the dust removal fluid 7, filter layers 16 and 17 are submerged. The air supply pipe 30 leads exhaust air from the suction mechanism through a port of the dust collection container, to the dust removal fluid below the filter layers after passing the filter layers 16 and 17.SELECTED DRAWING: Figure 1 【課題】セメント質の粉塵を、効率的且つ長時間安定して除去し粉塵量を低減できる除去装置を提供する。【解決手段】除去装置１は、吸込み管４０と、吸引機２０と、送気管３０とからなる吸引機構と、集塵容器４とを具備している。集塵容器４内部には、除塵液７が貯留されている。除塵液７にはフィルタ層１６，１７が沈設されている。送気管３０は、吸引機構からの排気を集塵容器口より、フィルタ層を１６，１７通過し、フィルタ層下の除塵液に導く。【選択図】図１
