Description

Folding-resistant filtering material

Technical Field

The utility model belongs to the technical field of filter materials, and particularly relates to a folding-resistant filter material.

Background

In recent years, people pay more and more attention to occupational hazards, disputes caused by occupational diseases are frequently reported, the protection requirements of people on workplaces with high dust content such as factories and mines are higher and higher, and air pollution is more and more serious along with rapid development of industry and mass use of fossil fuels. In addition to industrial applications, filter materials are also commonly used as air filtration media for transportation vessels and home ventilation systems; however, the common air filtering material can not well solve the problem of poor filtering effect caused by folding, only can filter dust in wind and has no good adsorption effect on peculiar smell in the wind; when the melt-blown layer is used as an air inlet surface, the melt-blown layer is easy to damage, and the large and small particles cover the surface to cause poor air permeability of the material, so that the service life is shortened. Therefore, the folding-resistant filter material provided by the utility model has good filtering effect, has folding resistance, can adsorb peculiar smell, and prolongs the service life of the filter material.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides the folding-resistant filter material which has good filter effect, folding resistance, can adsorb peculiar smell and prolongs the service life of the filter material.

In order to realize the functions, the technical scheme adopted by the utility model is as follows: the folding-resistant filtering material comprises a filtering material, wherein the filtering material is arranged in a W-shaped structure, so that the folding resistance of the filtering material is enhanced, and the service life of the filtering material is prolonged; filter material includes filter screen, first layer non-woven fabrics, second floor non-woven fabrics and third layer non-woven fabrics, filter screen, first layer non-woven fabrics, second floor non-woven fabrics and third layer non-woven fabrics arrange from outside to inside in proper order.

Furthermore, the filter screen is an elastic stainless steel metal net, has certain elasticity and flexibility, enables the filter material to have certain folding resistance, and can block large particles in the air.

Further, first layer non-woven fabrics is the wave structure setting, first layer non-woven fabrics is antiseized non-woven fabrics, and the first layer non-woven fabrics can protect the second floor non-woven fabrics as the windward side and avoid the air inlet harm, and the straight windward atress of first layer non-woven fabrics is avoided in the wave setting simultaneously, prolongs filtering material life to a certain extent.

Furthermore, the second layer of non-woven fabric is melt-blown non-woven fabric, and harmful dust in air is filtered.

Furthermore, activated carbon particles are added in the first layer of non-woven fabric and the second layer of non-woven fabric, the activated carbon particles have strong adsorption capacity, and the surface area of the activated carbon particles is large, so that the activated carbon particles can be fully contacted with peculiar smell gas to adsorb peculiar smell and play a purification role.

Furthermore, the third layer of non-woven fabric is hot-rolled non-woven fabric, so that the stiffness of the fabric is improved, dead angles after pleating are reduced, and the fabric has foldability.

The utility model adopts the structure to obtain the following beneficial effects: according to the folding-resistant filtering material provided by the utility model, the filtering material is of a W-shaped structure, the folding resistance of the filtering material is enhanced, the service life of the filtering material is prolonged, larger particles in air can be blocked through the arrangement of the filtering net, the first layer of non-woven fabric can be used as a windward side to protect the second layer of non-woven fabric from being damaged by air intake, meanwhile, the straight windward stress of the first layer of non-woven fabric is avoided through the arrangement of the first layer of non-woven fabric, the service life of the filtering material is prolonged to a certain extent, harmful dust in wind is filtered through the arrangement of the second layer of non-woven fabric, the stiffness of the cloth is improved through the arrangement of the third layer of non-woven fabric, dead corners after pleating are reduced, and meanwhile, the folding-resistant filtering material has foldability.
