Abstract
A kind of underground mine use Flexible Safety Air Filter, comprise the mesh sheet body woven by polyethylene nettle, mesh is formed at described mesh sheet body, described mesh sheet body fabric width is 2-5m, described mesh sheet body thickness is 2.5-3.0mm, and described mesh shape is rhombus, and the described mesh length of side is not more than 5mm, be provided with limit rope in the edge of described mesh sheet body, form the support to mesh sheet.The utility model has fire-retardant, antistatic property efficiently; Tensile force, shock resistance are good; High temperature resistant, corrosion-resistant, nontoxic, odorless; The feature such as lightweight, easy for installation.Especially when underground coal mine uses, well can play dust-proof effect, application life is than long.
Description
Technical field
The utility model relates to underground coal mine articles for use technical field, is specifically related to a kind of underground mine use Flexible Safety Air Filter.
Background technology
Underground mine use Flexible Safety Air Filter utilizes aerodynamic principle, certain geometrical shape, percent opening and different hole shape combination dust suppression and wind proofing wall is processed into according to enforcement site environment wind tunnel experimental results, make the air of circulation from during outward by body of wall, the air-flow of upper and lower interference is formed to reach outside high wind inside body of wall, the weak wind in inner side, the little wind in outside, the effect that inner side is calm.Adopt at underground coal mine, dig work plane when using, depositing dust, dust-proof, the diffusion that prevents coal dust, dust can be played.Air Filter in existing structure is shorter for application life, and individual layer dust-proof effect is poor.
Utility model content
Technical problem to be solved in the utility model is that providing a kind of is formed simply, and cost is low, the underground mine use Flexible Safety Air Filter of good dustproof effect.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of underground mine use Flexible Safety Air Filter, comprise the mesh sheet body woven by polyethylene nettle, mesh is formed at described mesh sheet body, described mesh sheet body fabric width is 2-5m, described mesh sheet body thickness is 2.5-3.0mm, and described mesh shape is rhombus, and the described mesh length of side is not more than 5mm, be provided with limit rope in the edge of described mesh sheet body, form the support to mesh sheet.
Described mesh sheet middle part is provided with a support rod.
Described limit rope is connected with clasp, and facilitate the stretching of mesh sheet, described clasp inwall is provided with notch, prevents clasp in connection procedure from skidding.
The beneficial effects of the utility model are: the utility model has fire-retardant, antistatic property efficiently; Tensile force, shock resistance are good; High temperature resistant, corrosion-resistant, nontoxic, odorless; The feature such as lightweight, easy for installation.Especially when underground coal mine uses, well can play dust-proof effect, application life is than long.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of underground mine use Flexible Safety Air Filter, comprise the mesh sheet body 1 woven by polyethylene nettle, mesh sheet body 1 is formed mesh 2, and mesh sheet body 1 fabric width is 2-5m, and mesh sheet body 1 thickness is 2.5-3.0mm, mesh 2 shape is rhombus, and mesh 2 length of side is not more than 5mm, is provided with limit rope 3 in the edge of mesh sheet body 1, forms the support to mesh sheet.Limit rope 3 is connected with clasp, and facilitate the stretching of mesh sheet, clasp inwall is provided with notch, prevents clasp in connection procedure from skidding.
Underground mine use Flexible Safety Air Filter adopts high density polyethylene (HDPE) as main raw material(s), add age resister, crosslinked hardening agent, fire retardant, antistatic additive plurality of reagents, fully mix, stir, take out and draw wire, be woven into special cancellated flexible mesh sheet, mesh sheet fabric width 2-5 rice, the width required according to user and length are carried out cut-parts to mesh sheet, are sewed, the underground mine use Flexible Safety dustproof shade of all size model needed for user that is made.
This product is mainly used in making underground mine use flexible dustproof curtain, for the depositing dust, dust-proof of Coal Exploitation, pick work plane, block coal dust, dust, coal dust to external diffusion.Single-layer flexible dustproof shade effect can reach 65 ~ 85%, and Double-level Reticulated is arranged, and greatly can improve anti-dust effect, anti-dust effect can reach more than 90%, effectively limit the generation of reentrainment of dust.
1. ultimate strength × extension at break
Ultimate strength (the kN) × extension at break (mm) in length and width direction: be not less than 50kNmm.
2. seam areas tension is powerful
Seam areas tension brute force is not less than ultimate strength.
3. trapezoidal method Tear strength
The trapezoidal method Tear strength in length and width direction is not less than 5% of correspondence direction ultimate strength.
4. sheet resistance
The upper and lower sheet resistance arithmetic mean of instantaneous value of Air Filter is all not more than 3 × 10
8Ω.
5. fire resistance
The fire resistance of flexible dustproof net meets following table and requires:
6. maintenance
This product adopts special weaving, knits out uniqueness anastomose effectively, even if there is scraping, breakage, also linearly can not open knot, convenience easy to maintenance, directly tie up with cord in the mesh of breakage.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
