Description

Mine-used machine-following type dustproof mask capable of adjusting air quantity and humidity

Technical Field

The invention relates to the technical field of mining tools, in particular to a mine machine following type dustproof mask capable of adjusting air volume and humidity.

Background

Mine pneumoconiosis has become the most serious occupational disease of coal mines at present, and accounts for more than 95% of occupational diseases of mining areas. The main reason causing the pneumoconiosis of coal miners is that most dust workers can inhale a large amount of dust to be accumulated in the lung under the severe working environment for a long time, and in addition, the self dust mask fails and the self-cognition of the workers is not strong. Every year, pneumoconiosis causes direct economic loss to countries of hundreds of millions of yuan, and causes adverse effects abroad. Therefore, prevention of dust hazards and prevention of pneumoconiosis are currently very important tasks. The individual safety protection is used as the last line of defense of occupational health safety protection, and is an important measure for effectively preventing the mine pneumoconiosis. With the continuous use of mechanized and intelligent equipment of coal mines, the labor intensity of workers is effectively reduced, the dust content of a working place is greatly improved, the concentration of mine dust is difficult to be reduced below a sanitary standard by only dust removal equipment, and the dust concentration is seriously exceeded in special places such as high-speed operation of a coal mining machine. Therefore, it is very important to wear a dust mask with high dust-proof efficiency and low breathing resistance.

At present, most of the self-suction type dustproof masks are adopted in China, and the self-suction type dustproof masks are characterized by simple structure, low cost and poor mask sealing performance, and if the masks are not in tight contact with the face, air leakage can occur to seriously reduce the dustproof effect. Meanwhile, the breathing resistance of the mask is increased along with the increase of the dust filtering amount. For example, chinese utility model patent publication No. CN214318895U discloses a mine dust mask, which comprises a face mask, the top of which is fixedly provided with a nose bridge fitting part. The mine site dust mask is characterized in that the expansion spring, the abutting block, the frame, the filter element, the stepped hole, the pull rod, the inserting block and the inserting block are arranged, the pull rod is pulled, the inserting block is pulled, the connecting spring is compressed, the inserting block moves out of the clamping groove, the abutting block moves upwards under the elastic force of the expansion spring, the frame and the filter element are ejected out, the frame and the filter element are taken out, a new frame and a new filter element are inserted into the groove, the frame extrudes the abutting block, and the abutting block moves, when the inserting block is inserted into the clamping groove under the elasticity of the connecting spring, the replacement is completed, the supporting spring is stretched by pulling the primary dustproof cloth, the primary dustproof cloth is loosened, the supporting spring gradually stretches and moves to make the dust of the primary dustproof cloth fall down by vibration, thereby prevented that elementary dustproof cloth from being influenced the gas permeability by the dust accumulation, solved inconvenient change, the problem of dust accumulation, nevertheless this type dust mask still can't avoid the problem of laying dust.

In addition, the power air supply type dust mask designed in China mainly adopts the modes of increasing a fan, a battery and the like, the load is increased for a person wearing the dust mask, the air delivery pipe surrounds the mask to seriously affect the operation comfort and efficiency of workers, particularly, a driver of a coal mining machine needs to follow the machine for operation, when the coal mining machine starts to cut coal, a large amount of coal rock dust can be generated, the dust is greatly raised under the flushing of fresh air flow, the coal rock dust concentration in a working face space is very high, when the driver of the coal mining machine wears the dust mask to follow the machine for operation, the breathing can be extremely unsmooth, the tired feeling of the driver is seriously increased, the physical strength is caused, meanwhile, the conventional mask is difficult to comprehensively filter the dust, and the driver still has the maximum probability of suffering from pneumoconiosis. Power-driven protective masks, efficient dustproof masks and the like appear earlier abroad, but are not widely promoted all the time due to the restriction of dustproof effect and use convenience, and the problem of the appearance of the power-driven protective masks and the efficient dustproof masks is solved by urgently needing a mining machine-following type dustproof mask with adjustable air volume and humidity.
