Description

Self-suction filtration type nanometer dust mask for coal mine

Technical Field

The invention belongs to the technical field of dust masks for coal mines, and particularly relates to a self-absorption filter type nanometer dust mask for coal mines, which is suitable for being used as a protective article by coal mines or workers engaged in and contacting dust.

Background

As far as the inventor knows, the self-priming filtering dust mask used in the coal mine or the workers engaged in and exposed to dust has the following problems: 1. the dustproof mask with high filtering efficiency has high breathing resistance, people wearing the dustproof mask for a long time can feel suffocated, and particularly, people engaged in certain physical labor work abandon wearing the dustproof mask due to the influence of the breathing resistance, so that the health of the people is influenced; 2. some dust masks with small volume can breathe smoothly only by using for a short time, and the breathing resistance can rise sharply after working for several hours, so that the requirement of long-time use cannot be met. 3. The accessible is changed filtering material by oneself and is guaranteed filtration efficiency and long-time use can smoothly breathe dust mask, and is bulky, weight is heavy, the dead space is bulky, carries and wears all inconveniently, influences the security of work even because of influencing wearer's the field of vision. 4. The same mask has single function, only can provide one kind of protection, and cannot meet the requirement of a user on protection diversification.

Disclosure of Invention

The invention aims to overcome the defects and provides a self-absorption filter type nanometer dust mask (hereinafter referred to as nanometer dust mask) for coal mines, which uses a plurality of layers of nanometer filter screens with flame retardant and antistatic performances as the filter material of the mask, wherein the nanometer filter screens are combined and spaced from each other; the material has low respiratory resistance and high filtering efficiency (the single-layer filtering efficiency is more than 95 percent), so that a user can wear the nano dust mask for a long time and still breathe smoothly. Meanwhile, a user can replace the nano filter screen by himself to ensure the filtering efficiency and prolong the service time of the dustproof mask, and the layer number of the nano filter screen can be freely selected according to the working environment and the requirement on the filtering efficiency; the nano filter screen has flame retardant and antistatic properties, so that the use requirement of coal mines on non-metallic materials is met, and the nano filter screen can be used in coal mines and other environments; the antistatic performance of the nano filter screen can prevent the surface of the nano filter screen from generating static adsorption dust to increase the breathing resistance, thereby prolonging the service life of the nano dust mask; in addition, because the filtering effect of the nano dust-proof screen is still more than 95 percent after the nano dust-proof screen is cleaned by using purified water, the nano dust-proof screen can be repeatedly used, and the service life of the nano dust-proof mask is prolonged again; because the nanometer filter screen has light weight and thin thickness, the mass and the volume of the nanometer dustproof mask can be reduced (the total thickness of the filter element is less than 11.5 mm) through reasonable structural design, the wearing comfort is improved, and the visual field of a user is not influenced; the filtering material user of nanometer dust mask can change by oneself, so the nanometer filter screen can be changed into other materials (like active carbon or filter pulp, but not limited to) or use with other multiple material cooperations to increase the protection kind of nanometer dust mask, satisfy the demand of user to the protection is diversified.

The technical scheme of the invention is realized as follows: a self-priming filtering type nanometer dust mask (hereinafter referred to as nanometer dust mask) for coal mines comprises a dust mask base body, a filtering bin, a locking nut, a filter element (composed of a filter element framework and a filtering material, wherein the filtering material is a nanometer filtering net with flame retardant and anti-static performances, but not limited to, and a protective cover; the base body of the dust mask is made of soft materials (not limited) such as cotton cloth or canvas, the materials meet the use requirements of coal mines on non-metal materials, and the wearing comfort and the close fit with the face of the nanometer dust mask are guaranteed; the filter bin, the locking nut and the filter element framework of the filter element are made of PC materials (not limited) with flame retardant and antistatic properties, and the materials meet the use requirements of coal mines on non-metal materials; the filter bin penetrates through the dustproof mask base body, and the filter bin is fixed on the dustproof mask base body through the locking nut; the filter element is arranged in the filter bin and is fixed through a protective cover, and a user can remove the protective cover and replace the filter element by himself; the number and the type of the filter elements can be determined by a user according to the environmental protection requirement, and the filter element framework can control the spacing distance of the filter materials so as to reduce the breathing resistance; the filter bin is connected with the locking nut and the protective cover through screw threads (without limitation).
