PROBLEM TO BE SOLVED: To remove dust by remote work.SOLUTION: A dust removing device 1 includes a cover structure body 2, a blower 4, a dust removing filter 5, a suspending bail 6, and a cable hanger 35. In the cover structure body 2, panels 16, 17, 18a, 18b, 19a, 19b and 20 are attached to a front surface upper part, a rear surface, right and left side surfaces and an upper surface of a frame 7 of a framed structure, and a lower end is opened, and an opening 3 is provided on a front surface. The dust removing device 1 is suspended by a crane through the suspending bail 6 to be conveyed, and is arranged so that a work place X on a work table Y can be covered with the cover structure body 2. The blower 4 is operated in this state, and thereby, gas 33 suctioned from the outside of the cover structure body 2 is turned into clean gas 33a through the dust removing filter 5, and then, is blown into the inside of the cover structure body 2, and the work place X is turned into the clean environment where the dust is removed.SELECTED DRAWING: Figure 1 |
