Industrial Dustproof Ceiling

Abstract

The invention provides an industrial dustproof ceiling applied to material piles in material processing places in a mine, a harbor, a power plant and a steel factory; the industrial dustproof ceiling is a roof structure, and covers the material pile so as to reduce airflows above the material pile; the air can penetrate the ceiling material so as to enter the ceiling; the industrial dustproof ceiling is provided with a slope structure, so snow and water can slide down through the slope structure. The industrial dustproof ceiling with no snow piling can greatly reduce load and force bearing on the structure surface when compared with a conventional roof structure, thus greatly reducing consumption and cost of other building materials; the slope structure is formed by a plurality of oblique netted units, and opening holes on the oblique netted units allow air to pass; water drops cannot directly penetrate the oblique netted units, thus protecting the material piles from being wetted.

Description

technical field [0001] The invention relates to a structure for suppressing flying dust, in particular to an industrial dustproof ceiling. Background technique [0002] Existing method for suppressing stockpile dust, the first kind is to arrange dust-proof net around the stockyard, and dust-proof net can suppress the dust of stockpile to distribute, the name of the U.S. patent is called wind barrier, and the patent No. is that US3226091 discloses this A kind of dust-proof net facility; Japanese patent, title is called dust suppression fence, and the patent No. is that the patent of JPS56136711 (A) also discloses this dust-proof net facility. The disadvantage of this technology is that without a roof, only relying on the fence cannot effectively prevent the air turbulence at the top of the stockpile, especially for the relatively large stockpile. [0003] The second is to protect the stockpile by building a fixed solid wall around the stockyard and an airtight ceiling struct...

Problems solved by technology

The disadvantage of this technology is that without a roof, only relying on the wall cannot effectively prevent the air turbulence at the top of the stockpile, especially for the relatively large stockpile

[0003] The second is to protect the stockpile by building a fixed solid wall around the stockyard and an airtight ceiling structure on the top. The disadvantage of this technical solution is that dust will be generated inside the building due to the operation of mechanical equipment, and the internal floating dust cannot be distributed. The working environment deteriorates and presents a risk of dust explosions

[0004] The third is to build a mesh structure roof supported by steel cables on the top of the yard, which can allow some air to pass through the roof structure, but this technology has the problem of huge pressure on the steel cables caused by snow accumulation

The snow cannot be evenly distributed on the roof, and too thick snow in local areas will lead to local high pressure, which not only increases the input cost of the supporting structure, but also is very expensive to manufacture such a huge pressure-bearing mesh material
