Description
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 big occupation disease of China first, and situation is the severeest, it is necessary to cause the great attention of the departments concerned.
On February 13rd, 2015, legal system net report: at present, China is engaged in the number of the enterprise about 16,000,000 that poisonous and harmful produces, 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 the most at the forefront in the world.The direct economic loss that China causes because of occupation disease, industrial accident every year about reaches 100,000,000,000 yuan, and indirect economic loss about reaches 200,000,000,000 yuan." whole nation report of occupational disease situation " announced according to Ministry of Public Health is introduced, and pneumoconiosis accounts for the 79.96% of occupation disease sum.It it is the most occupation disease of patient.Pneumoconiosis there is no radical cure method at present, and mortality rate is high.In pneumoconiosis, Pneumoconiosis and pneumosilicosis account for 91.89%.
According to Coal Mine Safety Supervision Bureau of country, National Federation of Trade Unions's investigation: colliery, the whole nation 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 overweights, coal dust maximum concentration scope 198～3420 milligram/cubic metre, exceed national standard 49.5～855 times, have 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 labor protection portion director represents, coal industry pneumoconiosis is not the most effectively controlled, and occupational health work is substantially at blank.
Pneumoconiosis is the most preventable: one is to ventilate or smoke evacuation at working environment, makes concentration of narmful substance control under state health standards；Two be be difficult to improve ventilated environment works time, effective dust mask will be worn.As long as accomplishing 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.What the workman in the work of mine operation face wore now has two big classes substantially: mask and dust mask.It is poor that mask seals, and four sides leaks, the most inoperative to high concentrate dust；Dust mask seals preferably, but air inlet protection is poor, and filter course is the thinnest, it is impossible to stop that high concentrate dust enters respiratory tract.China's pneumoconiosis is at the forefront in the world, does not has effective personal security's protective articles so far.This situation is not changed decades, and mask and dust mask do not play protective action, and the coal worker's pneumoconiosis sickness rate being equipped with mask and dust mask does not lower.
Study new technology and method, in high concentrate dust enterprise, such as: the field popularization and application that the pneumoconiosis such as mine, Coal Industry, diamond cutting are more, from source, stop the generation of pneumoconiosis, be problem demanding prompt solution.The disease that never should allow this fully controllable system of pneumoconiosis continues to exist in China.
Summary of the invention
The invention provides a kind of annular filter formula Anti-pneumoconiosis face shield, it is provided with air filtration chamber, removal layer can be set in air filtration chamber as required, sterilizing layer, filter course, adsorption layer, one or more of the several functions such as clean layer, annular filter formula Anti-pneumoconiosis face shield of the present invention, due to by the flat filter mode of traditional 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 is up to 16 centimetres, it is mask thickness and more than 20 times of dust mask filter course thickness, such as special requirement, filter chamber can also lengthen on request；Mask and dust mask material unicity are innovated and are changed into multiple material combined filtration by annular filter formula Anti-pneumoconiosis face shield, air filtration chamber arranges multiple filter course, the material of each filter course is different, each independent effect of each filter course, forms multiple tracks effective dust protective barrier；Multiple filter courses are the most interrelated becomes a total system, jointly realizes dust safeguard function, accomplishes the real effectively protection high concentrate dust infringement to human body,
It is an object of the invention to be realized by technical scheme once:
A kind of annular filter formula Anti-pneumoconiosis face shield, including 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 position in air filtration chamber is respectively provided with on the cheek of two sides, the other end in air filtration chamber is air inlet, air filtration intracavity is provided with some filter courses, some filter courses arrange removal layer, sterilizing layer, filter course, adsorption layer, clean layer, the high concentrate dust gas in air filtration chamber is entered by air inlet, after some filter courses filter, suck cleaning gas by air intake valve.One-way cock is made up of valve venthole, valve block seat, valve block, valve air inlet, 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, and during air-breathing, valve is opened, and allows the gas of cleaning enter respiratory tract；Valve closing during expiration, prevents the waste gas of exhalation 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 into air filtration intracavity by the suction that pulmonary produces, and after some filter courses filter, sucks cleaning gas by air intake valve.
Air filtration intracavity is provided with some filter courses, and 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: pneumosilicosis, 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, it is desirable to have specific aim.The removal layer of setting, sterilizing layer, filter course, adsorption layer, clean layer in some filter courses, just by one 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.During expiration, valve is opened, and allows the waste gas of exhalation 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: air-breathing filters, and exhales unimpeded.
Annular filter formula Anti-pneumoconiosis face shield of the present invention provides the benefit that:
1, air filtration chamber overlength, has big adsorption capacity；
2, placing multiple filtering material in some filter courses, filter area is wide, and filtering accuracy is high；
3, the high concentrate dust infringement to human body can be effectively prevented；
4, it is suitable for the application of big vital capacity, breathes smooth and easy, there is no the feeling of oppression and heat of mask.
5, wide application, not only prevents pneumoconiosis, it is possible to escape when being used for protecting haze and fire；
