Abstract
The utility model discloses a high power seamless plastic air duct, which comprises an external coating, a seamless inner surface sealer, a steel ring, a reversed edge, a seamless middle casing ply, a special buttonhole selvage, a steel wire and an aluminum ring for suspension. The seamless middle casing ply is positioned between the external coating and the seamless inner surface sealer. The special buttonhole selvage and the seamless middle casing ply are made into a whole. The steel wire is positioned in the special purpose buttonhole selvage and is arranged along the lengthwise direction of the special buttonhole selvage. The aluminum ring for suspension is distributed along the lengthwise direction of the special buttonhole selvage and is positioned under the steel wire. The utility model has the advantages of high strength, low rate of air leakage, small windage, seamless circumferential entirety, soft texture, light weight, stable physical and mechanical property, superior safety performance, etc. The high power seamless plastic air duct resists the high temperature and the low temperature, stops combustion, resists the static electricity and has no pollution at the time of processing. The utility model is the first choice for the high mechanization large mine, the high power blower fan and the long-distance blowing.
Description
Technical field
The utility model relates to a kind of plastic cement air duct, and is especially relevant with the seamless plastic cement air duct of brute force.
Background technique
Existing pin is made the formula air duct, gluing rubber leather air duct, air duct products such as plastics leather air duct and the seamless air duct of inner bag, it is low to exist intensity, the air leak rate of air curtain height, easy breaking releasing when hanging, high and low temperature resistance, fire-retardant and anti-static electricity property is poor, can produce the toxic dust befouling environment during manufacturing influences deficiencies such as workers ' health.
Summary of the invention
The purpose of this utility model provides a kind of product strength height, and air leak rate of air curtain is low, and windage is little, the circumference integral seamless, quality softness, high-low temperature resistant, in light weight, Safety performance such as physical and mechanical properties is stable, and is fire-retardant, antistatic is good and add the seamless plastic cement air duct of free of contamination brute force in man-hour.
For achieving the above object, the utility model is achieved through the following technical solutions.Powerful seamless plastic cement air duct comprises outer coating layer, seamless internal surface sealing layer, steel ring, anti-limit, seamless central rib rack-layer, special-purpose buttonhole selvage, steel wire and hang and use the aluminium circle, seamless central rib rack-layer outside between coating layer and the seamless internal surface sealing layer, special-purpose buttonhole selvage and seamless central rib rack-layer are made one, steel wire is positioned at special-purpose buttonhole selvage, and arrange along special-purpose buttonhole selvage length direction, hang with the aluminium circle and distributes, and be positioned at below the steel wire along special-purpose buttonhole selvage length direction.
Described brute force is seamless plastic cement air duct, seamless central rib rack-layer adopt high-strength polyester fibers to be made into, and steel wire diameter is the 1-5 millimeter, and hanging with the spacing between the aluminium circle is the 300-900 millimeter, and outer coating layer is seamless coating layer.
The utility model compared with prior art has the following advantages: (one) be structurally guaranteed real seamless, central rib rack-layer, internal surface sealing layer, outer coating layer all are jointless structure, compressive strength can reach the 9000P handkerchief, tear edge can reach 300 Ns, and air leak rate of air curtain is lower than 0.5%, and internal surface is bright and clean, windage is little, reaching 3 times of traditional product working life, can satisfy the requirement of all blower fans both at home and abroad, is the first-selected product of high mechanization large-scale mine, high-power blower, long distance air-supply; (2) be the special-purpose buttonhole selvage structure of initiative, big air duct buttonhole selvage includes powerful steel wire, and never breaking releasing has guaranteed mine ventilation safety; (3) be-40 ℃ and do not harden that high temperature is not clamminess, easily folding, no folding line does not more have the jackknifing phenomenon; (4) manufacturing of hommization, the pollution of nonpoisonous and tasteless no dust, no glass is mining environment-friendly products, can significantly reduce cost and the labor intensity that changes air duct.
