Abstract

PROBLEM TO BE SOLVED: To provide a dust splash prevention tool capable of preventing splash of dust generated in a sealed space.SOLUTION: A dust splash prevention tool 1 (booth 2) comprises: four slide braces 10; four connection poles 14; four expandable poles 16; a suction filter 20; an exhaust plate 22; and a cure film (not shown in the figure). Air including dust in the booth 2 is exhausted to the outside of a building by an exhauster 30 via an exhaust tube 35. Even when the air in the booth 2 is exhausted, air outside of the booth 2 (-X side of the booth 2) is sucked in the booth 2 via the suction filter 20, and the inside of the booth 2 does not become a negative pressure state, capable of maintaining constant air pressure. Therefore, the air is not sucked from the outside of the booth 2 via a gap of the cure film (not shown in the figure), so that splash of the dust can be prevented.

Description

  The present invention relates to a dust scattering prevention tool for preventing dust scattering generated in a sealed space.

  Dust generated by indoor work such as interior construction of a building causes health problems for workers (for example, see Patent Document 1). Therefore, it is desired to collect dust efficiently and to keep the room clean. However, when the room is sealed by, for example, curing, even if the room air is exhausted using an exhaust fan, the room has a negative pressure and the dust collection efficiency is lowered. In addition, there is a problem that indoor dust is scattered when air enters the room through a gap or the like of the curing.

FIG. 1 is a diagram showing a configuration of a dust scattering preventer according to this embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to FIG.

  In FIG. 1, the structure of the dust scattering prevention tool 1 which concerns on this embodiment is shown. The dust scattering prevention tool 1 is assembled in a room of a building as an example. The dust scattering prevention tool 1 includes four slide columns 10, four connecting poles 14, four telescopic poles 16, an intake filter 20, an exhaust plate 22, a curing film (not shown), and an exhaust device 30.

  The four slide struts 10 are metal (or resin, wooden, etc.) struts that can be expanded and contracted within a range of 1800 to 3300 mm, for example. Two slide columns 10 are vertically provided on the floor surface F on the + Y side and the −Y side so as to be separated from each other in the X-axis direction, and their tips are fixed to a ceiling surface (not shown) of the building.

  The four connecting poles 14 are, for example, 1800 mm metal (or resin, wooden, etc.) poles. The two connecting poles 14 are connected to the vicinity of the upper ends and the lower ends of the two slide columns 10 on the + Y side, respectively, with their longitudinal directions directed in the X-axis direction. The remaining two connection poles 14 are connected in the vicinity of the upper end and the lower end of the two slide columns 10 on the −Y side, respectively, with their longitudinal directions directed in the X-axis direction.

  The four telescopic poles 16 are metal (or resin, wooden, etc.) poles that can be expanded and contracted in the range of 900 to 1700 mm as an example. Here, it is assumed that the length is fixed to 900 mm. The two telescopic poles 16 are connected in the vicinity of the upper end and the lower end of the two slide struts 10 on the + X side, respectively, with their longitudinal directions directed in the Y-axis direction. The remaining two telescopic poles 16 are connected in the vicinity of the upper end and the lower end of the two slide struts 10 on the −X side, respectively, with their lengths directed in the Y-axis direction.

  The intake filter 20 is fixed between the two slide columns 10 on the -X side and the telescopic pole 16 that connects the lower ends thereof. The intake filter 20 is composed of two rectangular wire meshes and a rectangular nonwoven fabric sandwiched between them. The nonwoven fabric is sandwiched between two wire meshes to maintain a shape that spreads across the entire surface.

  The exhaust plate 22 is fixed between the two slide columns 10 on the + X side and the telescopic pole 16 that connects the lower ends thereof. The exhaust plate 22 is, for example, an Alpolic plate (a three-layer aluminum resin composite plate using aluminum for the surface and resin for the core), and a circular opening 22a is formed on the −Y side. A metal net 32 is attached to the opening 22a.

  A curing film (not shown) is a sheet-like member made of, for example, polyethylene. The curing film is surrounded by two surfaces surrounded by the slide column 10 and the connecting pole 14 arranged on each of the + Y side and the −Y side, and a ceiling surface (not shown), using a vinyl tape or the like. Two surfaces, the surface surrounded by the slide column 10 arranged on the −X side, the upper telescopic pole 16 and the intake filter 20, and the slide column 10, the telescopic pole 16 and the ceiling surface (not shown). Surface, the surface surrounded by the slide column 10 arranged on the + X side, the upper telescopic pole 16 and the exhaust plate 22, and the surface surrounded by the slide column 10, the telescopic pole 16 and the ceiling surface (not shown). It is stretched on each. Thereby, the booth 2 which seals a work space is formed.

  The exhaust device 30 includes an exhaust fan 33, a dust collection filter 34, and an exhaust tube 35. The exhaust fan 33 is attached to the opening 22 a of the exhaust plate 22. When the exhaust fan 33 is operated, the gas in the booth 2 including dust is exhausted outside the booth 2 through the exhaust tube 35. The dust collection filter 34 is fixed between the exhaust port of the exhaust fan 33 and the exhaust tube 35. The dust collection filter 34 includes a plurality of filter cloths such as bag filters, and efficiently filters the dust collection contained in the air exhausted by the exhaust fan 33. The exhaust tube 35 is arranged from the dust collection filter 34 to the outside of the building.

  As described above in detail, according to the dust scattering prevention device 1 of the present embodiment, the four slide struts 10, the four connecting poles 14, the four telescopic poles 16, the intake filter 20, the exhaust plate 22, and the curing film (non-curing film) The booth 2 is constructed from the figure), and the gas containing the dust in the booth 2 is exhausted out of the building by the exhaust device 30 via the exhaust tube 35. Even if the gas in the booth 2 is exhausted, the gas is sucked into the booth 2 from outside the booth 2 (−X side of the booth 2) through the intake filter 20, so that the inside of the booth 2 does not become negative pressure. Maintain a constant atmospheric pressure. Thereby, scattering of dust is prevented without inhaling gas from outside the booth 2 through a gap or the like of a curing film (not shown).

  Moreover, even if the gas in the booth is exhausted outside the booth via the intake filter 20 by configuring the intake filter 20 including the nonwoven fabric, the dust is removed by the intake filter 20. That is, no dust is scattered outside the booth.

  In addition, the intake filter 20 and the exhaust plate 22 (opening 22a) are respectively disposed on one side and the other side in the X-axis direction with a space in the booth 2 interposed therebetween. Thereby, the entire gas in the booth 2 is efficiently replaced, and the dust in the booth 2 can be efficiently collected. The intake filter 20 and the exhaust plate 22 (opening 22a) are not limited to be disposed at positions facing each other, but may be disposed at a position sandwiching the entire space in the booth 2.

  The dust scattering preventive tool of the present invention is suitable for preventing dust scattering generated in a sealed space.
