Abstract
The utility model discloses a mining collapse resistance air duct, comprising a duct body, a hem vertically arranged along the duct body, a hanging ring disposed on the hem, a metal mouth ring which can integrate the single duct bodies with each other as a whole and disposed on the two ends of the duct body, and a flanging side, wherein the section of the duct body is a composite structure and is provided with polyurethane rubber, polyurethane glue, PVC, base cloth and PVC from inside to outside; the base cloth can use canvas, fiberglass cloth, glass cotton mixed weaving cloth or reinforced chemical fiber cloth; the interior and the exterior of the base cloth are coated with the PVC, which can advance the shock resistance of the base cloth; and the inner layer is compounded with a layer of polyurethane film based on coated with the PVC, which can largely reduce the wind resistance and enhance the ventilation efficiency. The mining collapse resistance air duct of the utility model coats the PVC on the two surfaces of the base cloth, compounds the polyurethane film on the inner layer, and has high intensity compared with the present mining air duct, thereby having shock resistance, tear resistance, longer life, small wind resistance and high ventilation efficiency, applicable for the blasting mining working face.
Description
Technical field
The utility model relates to mining air duct technical field, especially a kind of mining blast-proof air duct.
Background technology
China is a coal big country, and the coal resources reserves are abundant, because the formation of mineral products mechanism is different, causes the geologic structure of each mine, mineral ore different, and wherein the shared proportion of girdle, low reserves colliery is bigger.Along with the anxiety of energy situation, the exploitation in girdle, low reserves colliery also comes into one's own day by day.Because balk, the reserves in such colliery are little, mine is short, therefore modern coal-cutting machinery is equipped with comparatively difficulty, and big gun is adopted becomes main mining type.For emptying construction operation place as early as possible by blowing out smog and other pernicious gases that produces, make operating location maintenance good visibility, temperature and humidity, just must ventilate to the job location, to supply with sufficient fresh air, at present, during for various tunnellings such as total rock lane, colliery, half coal rock tunnel, full coal rock tunnel, tunnels, generally all adopt forced ventilation, promptly blower fan be installed in fresh distinguished and admirable in, with air duct fresh air is delivered to the job location.In order to guarantee ventilation effect, " safety regulations in coal mine " regulation: total rock tunnel, colliery wind distance must not be greater than 12 meters; Alternate heading wind distance must not be greater than 7 meters; Full coal petrography tunnel wind distance must not be greater than 5 meters.When its reason is that the wind distance is excessive, the face air volume deficiency, pernicious gas can not in time be got rid of, and occurs methane accumulation easily, is unfavorable for safety in production; When the wind distance was too small, face air volume was excessive, and the dust with work plane blows afloat easily, and Dust Capacity is transfinited, and does not also meet the regulation of safety code.The mining air duct of existing use has rigidity air duct and soft wind letter, the rigidity air duct is after adopting rubber tile or glass fiber reinforced plastic to make tubular, at its two ends linkage being set forms, its shortcoming is that wind is apart from adjusting, for the apoplexy of guaranteeing to construct apart from not transfiniting, it is long every joint cylindrical shell have to be made as required the joint that is about different sizes such as 10 meters, 5 meters, 3 meters, 2 meters.The back dense smoke of blowing out disperses, and before the joint length that requires according to reality is articulated in former cylindrical shell with required cylindrical shell, ventilates; When blowing out once more, should save cylindrical shell earlier and take, in order to avoid the rubble that is splashed is broken, broken but still keep away unavoidably sometimes, this method of operating was both taken a lot of work, was required great effort, and had increased operating personnel's labour intensity, can't realize again guaranteeing the wind distance at short notice, bring hidden danger to safety in production.Its reason is that glass steel air duct does not have flexibility, broken up easily, though and rubber tile system air duct has certain flexibility, intensity is low is also broken easily; Soft air duct system weaves cotton cloth or chemical fabric etc. is the adhesive plaster ventilating duct that framework material and rubber are made with cotton the mixing of glass fabric, glass, wind is apart from adjusting easily, but its flowing resistance is big, there is intensity difference, is out of shape shortcomings such as big, and the sillar, the coal cinder that are easy to be collapsed by explosion damage, and are unwell to the ventilation of blast mining face.As disclosedly designing in State Intellectual Property Office on December 24th, 2003 by Lin Yakun, the patent No. is 02292096.x, the utility model patent that name is called " the mining air duct of telescopic type " has solved wind preferably apart from the adjustment problem, but its bag is formed by the sealing-in of lightweight glued membrane fibrous woven cloth, be easy to the sillar that collapsed by explosion, coal cinder damages, in the use when work plane will be blown out, need air duct is bounced back, up to being in outside the rubble bombardment, be positioned at the air duct elongation within the wind distance of regulation up to its end again after blowing out, because dense smoke and the coal dust of big gun after adopting makes the work plane low visibility, so operating difficulties, it is promoted the use of and is restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of shock resistance, tear-proof, be suitable for that blast mining face uses, the life-span is long, easy to connect, the mining blast-proof air duct of good airproof performance, and it can effectively prevent to adopt the damage that explosion causes owing to big gun.
The purpose of this utility model is achieved by the following technical solution:
A kind of mining blast-proof air duct, comprise cylindrical shell, along the vertical flanging that is provided with of cylindrical shell, be arranged at the hanging ring on the flanging, single cylindrical shell can be connected to each other to the metal mouth circle and the flange that are arranged at the cylindrical shell two ends of one, its special character is that the cross section of described cylindrical shell is a composite construction, be followed successively by polyurethane rubber from inside to outside, polyurethane adhesive, PVC, base cloth, PVC, base cloth can adopt canvas, glass fabric, glass is cotton to be mixed and weaves cotton cloth or strengthen chemical fabric, inside and outside base cloth, apply PVC, can improve the shock resistance of base cloth, compound one deck polyurethane film on the basis of internal layer coating PVC, can reduce windage greatly, improve drafting efficiency.
A kind of mining blast-proof air duct, the flanging that comprises cylindrical shell, vertically is provided with along cylindrical shell, be arranged at hanging ring on the flanging, single cylindrical shell can be connected to each other to the metal mouth circle and the flange that are arranged at the cylindrical shell two ends of one, its special character is that the cross section of described cylindrical shell is a composite construction, is followed successively by polyurethane rubber, polyurethane adhesive, PVC, base cloth, PVC, base cloth, PVC from inside to outside.It has increased one deck base cloth on the basis of above-mentioned air duct, its tearing toughness is further improved.
Mining blast-proof air duct of the present utility model at the dual coating PVC of its base cloth and at internal layer composite polyurethane film, is compared with existing mining air duct, the intensity height, so shock resistance, tear-proof, life-span are also longer; Windage is little, and the drafting efficiency height is suitable for blast mining face and uses.
