Description

Annular filter formula Anti-pneumoconiosis face shield

Technical field

A kind of annular filter formula Anti-pneumoconiosis face shield, belongs to articles for labour protection technical field.

Background technology

On February 7th, 2015, the Chinese Central Television's [Focus] host respects a pellet and says, pneumoconiosis has become the first occupational disease of China, and situation is very severe, must cause the great attention of the departments concerned.

On February 13rd, 2015, legal system net is reported: at present, and China is engaged in the number of the enterprise about 1,600 ten thousand that poisonous and harmful is produced, about number about 200,000,000 people of contact Occupational Hazard Factors.China's Occupational Disease Hazards reach, number of patients and neopathy number are all at the forefront in the world.The direct economic loss caused because of occupational disease, industrial accident every year reaches 1,000 hundred million yuan, and indirect economic loss reaches 2,000 hundred million yuan." the national report of occupational disease situation " announced according to the Ministry of Public Health is introduced, and pneumoconiosis accounts for 79.96% of occupational disease sum.It is the occupational disease that patient is maximum.Current pneumoconiosis there is no radical cure method, and the death rate is high.In pneumoconiosis, Pneumoconiosis and silicosis account for 91.89%.

According to national Coal Mine Safety Supervision Bureau, National Federation of Trade Unions's investigation: national colliery has 2,650,000 to meet dirt personnel, has 5.7 ten thousand people to suffer from pneumoconiosis every year, every year because of Death from Pneumoconiosis more than 6000 people, is the twice of industrial accident death toll.Most underground coal mine dust concentration severe overweight, coal dust maximum concentration scope 198 ~ 3420 milligrams/cubic metre, exceedes national standard 49.5 ~ 855 times, has a large amount of worker to suffer from pneumoconiosis every year.Whole nation coal mining enterprise adds up Pneumoconiosis Patients 440,000 example, and pneumoconiosis recall rate is up to 7.2%.National Federation of Trade Unions labour protection portion director represents, coal industry pneumoconiosis is not also effectively controlled, and occupational health work is in blank substantially.

Pneumoconiosis can prevent completely: one is ventilate or smoke evacuation at operating environment, makes concentration of narmful substance control under state health standards; Two be be difficult to improve work in ventilated environment time, effective dust mask be worn.As long as accomplish above 2 points, pneumoconiosis would not occur.

At present, coal production environment depositing dust work progress is slow, if stop pneumoconiosis in source, personal protection has become unique channel.That wears now the workman of mine operation face work has two large classes substantially: mouth mask and dust mask.Mouth mask sealing is poor, and four sides leaks, substantially inoperative to high concentrate dust; Dust mask sealing is better, but air inlet protection is poor, and filter course is very thin, cannot stop that high concentrate dust enters respiratory tract.China's pneumoconiosis is at the forefront in the world, does not have effective personal security's protective articles so far.This situation is not changed decades, and mouth mask and dust mask do not play protective action, and the coal worker's pneumoconiosis incidence of disease being equipped with mouth mask and dust mask does not lower.

Study new techniques and methods, in high concentrate dust enterprise, field as more in: pneumoconiosis such as mine, Coal Industry, diamond cutting is applied, and stopping the generation of pneumoconiosis from source, is problem demanding prompt solution.This complete controllable disease of pneumoconiosis never should be allowed to continue in China's existence.

Summary of the invention

The utility model provides a kind of annular filter formula Anti-pneumoconiosis face shield, be provided with air filtration chamber, in air filtration chamber, as required can removing layer be set, sterilizing layer, filter course, adsorption layer, one or more of the several functions such as clean layer, the utility model annular filter formula Anti-pneumoconiosis face shield, due to the flat filter mode by traditional mouth mask and dust mask, annular filter mode is changed in innovation, add the length of filter chamber, general unidirectional length 8 centimetres, two-way length can reach 16 centimetres, it is more than 20 times of mouth mask thickness and dust mask filter course thickness, as special requirement, filter chamber can also lengthen on request, mouth mask and the innovation of dust mask material unicity are changed into multiple material combined filtration by annular filter formula Anti-pneumoconiosis face shield, in air filtration chamber, multiple filter course is set, the material of each filter course is different, and the independent effect separately of each filter course forms the effective dust protective barrier of multiple tracks, multiple filter course is interrelated again becomes a total system, jointly realizes dust safeguard function, accomplishes that real effectively protection high concentrate dust is to the infringement of human body,

The purpose of this utility model is realized by once technical scheme:

A kind of annular filter formula Anti-pneumoconiosis face shield, comprise air intake valve, sealing paste, drain tap, face shield, it is characterized in that: air intake valve is arranged on the one end in air filtration chamber, the other end in air filtration chamber is air inlet, be provided with some filter courses in air filtration chamber, removing layer, sterilizing layer, filter course, adsorption layer, clean layer are set in some filter courses, entered the high concentrate dust gas in air filtration chamber by air inlet, after some filter courses filter, suck clean air by air intake valve.One-way cock is made up of valve venthole, valve block seat, valve block, valve air admission hole, and air intake valve is identical with drain tap structure.

Air intake valve is arranged on the one end in air filtration chamber, is arranged near nostril, and air intake valve is one-way cock, valve open during air-breathing, allows clean gas enter respiratory tract; Valve closing during expiration, prevents the waste gas of breathing out from entering air filtration chamber.

The other end in air filtration chamber is air inlet, and air inlet communicates with the gas outside face shield, and gas is sucked in air filtration chamber by the suction that lung produces, and after some filter courses filter, sucks clean air by air intake valve.

Be provided with some filter courses in air filtration chamber, the quantity of filter course and material are different and change according to handled gas property.There are 12 kinds of legal pneumoconiosis in China: silicosis, coal-worker's pnuemoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestos pneumoconiosis, talc pneumoconiosis, cement pneumoconiosis, mica pneumoconiosis, kaolin pneumoconiosis, aluminosis, electric welding pneumoconiosis and foundry worker pneumoconiosis.These pneumoconiosis can not be protected by unified method, need specific aim.The removing layer arranged in some filter courses, sterilizing layer, filter course, adsorption layer, clean layer, just with a kind of when needs are a kind of, when needing to use more kinds of, can exceed present scope, with more kinds of.

Drain tap is identical with air intake valve structure, is also one-way cock.Valve open during expiration, allows the waste gas of breathing out discharge rapidly; Valve closing during air-breathing, prevents outside air from entering.Air intake valve and drain tap are alternately opened, are closed, and form the benign cycle of gas: inhale filter, exhale unimpeded.

The beneficial effect of the utility model annular filter formula Anti-pneumoconiosis face shield is:

1, air filtration chamber overlength, has large adsorption capacity;

2, place multiple filtering material in some filter courses, filter area is wide, and filtering accuracy is high;

3, can effectively prevent high concentrate dust to the infringement of human body;

4, be applicable to the application of large lung capacity, breathe smooth and easy, there is no the feeling of oppression and heat of mouth mask.

5, wide application, not only prevents pneumoconiosis, escapes when also can be used to protection haze and fire;
