Abstract
The invention discloses an air screen dustproof helmet and an air screen dustproof method. The helmet comprises a cap shell, a helmet sandwiched layer, a cap lining and a jowl band, wherein an air screen injection system and an air source are arranged on the helmet, and the air source is connected with the air screen injection system. The dustproof method comprises the following steps of: fixing the helmet by using the jowl band; connecting an air source pipeline; opening a gas cylinder valve or a compression air pressure reduction valve; regulating a valve on the helmet to make air form an air screen at a certain flow speed along a helmet face from a nozzle; regulating a branch pipe valve to lead a certain amount of air to enter from the helmet sandwiched layer; and forming positive pressure between the helmet face and the air screen. The air screen dustproof helmet is applied to a production place suffering harmful dust, and occupational hazard of dust to a worker can be effectively prevented; the dustproof helmet is free from limitation of a worker face, worker sight is not affected, the strength of the air screen can be regulated, the dustproof helmet can be applied to environments having different dust contents, and pneumoconiosis occurrence of employee can be effectively prevented or reduced, and safety production is ensured.
Description
Technical field
The present invention relates to a kind of Dust proof helmet and method, especially a kind of air curtain Dust proof helmet and method that prevents Mine Dust.
Background technology
In mining and industrial processes, tend to produce the mass production dust, these dust enter chronic, the damage of carrying out property lung fibrosis that lung and retention cause with human body respiration and are called pneumoconiosis.Common pneumoconiosis has: silicosis, anthracosis, cement pneumoconiosis, carbon ink pneumoconiosis, mica pneumoconiosis, foundry worker pneumoconiosis etc.This occupational disease is extremely serious to the infringement of health, and the treatment of pneumoconiosis there is no miracle cure at present, therefore to the individual dust-proof working of personnel for preventing having important practical significance of pneumoconiosis.
In the production, wet operation, sprinkle water and spray depositing dust, cleaner etc. are dustproof except taking in the serious workplace of dust pollution, the measurements for reduction, the staff also needs to wear the personal protection device, such as anti-dust respirator, the air-supply helmet, air-purifying respirator etc., used anti-dust respirator stops up mesh because breathing generation steam easily causes dust to be attached on the dirt filtrating screen in actual applications, cause respiratory resistance to increase gradually, and facial damp and hot, the comfortableness of librarian use is worn in impact; The air-supply helmet mostly is the sealing with eyepiece, the semi-enclosed helmet, because people's breathing easily forms water smoke at the eyepiece inwall, the eyepiece outer wall also easily is subject to adhering to of dust simultaneously, affects sight line and safety in production; Air-purifying respirator only is used for the dust protection of nose and mouth, and can not carry out the dust protection to eye.In order to solve dust harzard and to reduce the generation of pneumoconiosis, need research a kind of can effectively prevent dust on personnel's harm, need not clean and not affect the Dustproof helmet of personnel's sight line and safety operation.
Summary of the invention
Technical problem: the objective of the invention is to overcome weak point of the prior art, a kind of simple in structure, good dustproof effect is provided, can reduce the pathogenetic air curtain Dust proof helmet of pneumoconiosis and method.
Technical scheme: air curtain Dust proof helmet of the present invention, comprise the helmet that is formed by cap shell, helmet interlayer, hat lining, jowl band, the described helmet is provided with the air curtain nozzle system, connects the source of the gas of air curtain nozzle.Described air curtain nozzle system comprises air curtain nozzle, ventilation lumen, control valve, three-way pipe, flexible pipe, the arm that is located on the cap shell, air curtain nozzle is arranged on the cap shell shade, the arrival end of air curtain nozzle is connected with ventilation lumen one end, the other end of ventilation lumen is through three-way pipe difference connecting hose and arm, and flexible pipe connects source of the gas; Have on the cap shell and make arm enter the interior aperture of helmet interlayer; Described ventilation lumen is provided with control valve and Pressure gauge, also is provided with the arm valve on the arm; Described source of the gas comprises by the compressed air bottle of gas cylinder valve control or the compressed air line of being controlled by pressure-reducing valve.
Be provided with helmet interlayer pore between described helmet interlayer and the hat lining; The both sides ear of described cap shell is provided with listens the hole, listens in the hole dirt filtrating screen is housed; Described air curtain nozzle is made with engineering plastics.
The air curtain dust-control method of the above-mentioned helmet may further comprise the steps:
A. utilize the jowl band that the helmet is fixed on personnel's head;
B. connecting hose is regulated gas cylinder valve or pressure-reducing valve output squeezing air to source of the gas gas cylinder or compressed air line;
C. the air velocity by the ejection of control valve control air curtain nozzle is 4 ~ 9m/s, forms air curtain at the face door position of helmet cap shell, and blocking-up contains dusty gas and enters personnel's respiratory tract and eyes; Regulating simultaneously the arm valve, to make the air that enters helmet interlayer be 0.1 ~ 0.3m
3/ min, and gone out by helmet interlayer pore uniform-flow, to helmet face space forced draft, avoid dust laden air to enter the personnel's of attaching the names of pre-determined candidates face, take away simultaneously the part heat on the personnel crown of attaching the names of pre-determined candidates, carry out the head heat radiation.
Beneficial effect: the present invention is applicable at the serious Workplace of dust harzard, can realize the facial space of living in of staff and the isolation of outside dusty gas by the air curtain that air curtain nozzle forms, and makes the personnel of wearing avoid the harm of dust.Can effectively prevent dust to staff's occupational hazards, and the air curtain of this Dust proof helmet generation is not subjected to the restriction of personnel's shape of face; Air curtain intensity is adjustable, can adapt to the environment of different dustiness, and air curtain need not clean and not affect personnel's sight line, can effectively prevent or reduce the generation of practitioner's pneumoconiosis, guarantees safety in production.The occupational safety and health protector of tuberculosis sucks industrial dust in order to prevent the operating personnel, reduces the generation of pneumoconiosis.It is simple in structure, easy to use, effective, have widely practicality.
