Claims

[Scope of Claim for Utility Model Registration] (1) A dustproof device in which the four sides and top wall are surrounded by flexible sheets so that the protected device can be isolated from the dusty external atmosphere, and compressed air can be sealed inside. A portal-shaped pipe consisting of two vertical pillars made of a flexible material with pressure resistance and one horizontal beam attached to the top so as to be sandwiched between the pillars is spaced at a specified interval. The structure is such that the gantry pipes can be made to stand upright, and the two sides and the top wall of the gantry pipes can be successively increased to the required length by connecting and closing the two sides and the top wall with a flexible sheet fitted with a sealing fastener between the gantry pipes. . A dustproof device further comprising a flexible sheet that closes the front and rear sides of the parallel gate-shaped pipes as an instrument insertion opening and a worker entrance/exit. (2) Practical use characterized by connecting and reinforcing the connection between portal pipes with at least one straight horizontal column made of a flexible material with pressure resistance capable of sealing compressed air inside. A dustproof device according to claim 1 of the patent registration claim. (3) The dust-proofing device according to claim 1, wherein the air chamber of the portal pipe is divided into at least two sections. (4) The dustproof device according to claim 1 of the utility model registration, characterized in that a metal protector is attached to the upright base of the portal pipe and is fixed with the protector. (5) Connect all the air chambers of the multiple portal pipes that make up the device with piping via air valves,
2. The dustproof device according to claim 1, wherein the piping is connected to a compressed air supply device that maintains a predetermined pressure at all times. (6) The dust-proofing device according to claim 1, which is a combination of the features described in paragraphs 2 to 5 above.
