Description
Technical field
A kind of mining wind dust guard that changes capable of circulation of the utility model relates to a kind of mining wind dust guard that changes capable of circulation, belongs to the mine safety appliance field.Be particularly related to the circulation that a kind of inhalation cycle device, expiration EGR, head dust guard separate and change the wind dust guard pollution abatement equipment.
Background technology
The anti-dust respirator that in the colliery, uses at present, it is very sultry that the workman can feel after wearing a period of time, and comfort level and security can not suit in perfection; And most of mouth masks are after using once, and the active carbon in the mouth mask is difficult to change, and uses inconvenience; Though meet the demands on some mouth mask performances, carry the comparison heaviness, dustproof grade is all concentrated and is put together; Have on anti-dust respirator work for a long time, can increase the weight of workman's head load, reduce workman's operating efficiency.
Summary of the invention
In order to improve above-mentioned situation; The wind dust guard is changed in a kind of mining circulation of changing the wind dust guard and providing a kind of inhalation cycle device, expiration EGR, head dust guard to separate capable of circulation of the utility model, and can effectively alleviate the workman's head load that carries dust guard pollution abatement equipment for a long time and the sultry problem in the anti-dust respirator.
A kind of mining wind dust guard that changes capable of circulation of the utility model is achieved in that a kind of mining wind dust guard that changes capable of circulation of the utility model is made up of inhalation cycle device, expiration EGR, head dust guard three parts.The inhalation cycle device is changed fan, little air inlet pipe, motor, heat-insulating flame-retardant casket, supply unit, the hermetic seal piston that advances, middle air inlet packed-piston, final vacuum packed-piston, proof and electric leakage-proof safety casket and lead and is formed by air inlet active carbon filtering device, big air inlet pipe, air inlet; Closely be connected through the hermetic seal piston that advances between air inlet active carbon filtering device and the big air inlet pipe; There is air inlet to change fan in the big air inlet pipe; Motor is equipped with the heat-insulating flame-retardant casket outward; Link to each other with lead between motor and the supply unit; Supply unit is equipped with the proof and electric leakage-proof safety casket outward, has middle air inlet packed-piston closely to link to each other between lead and the big air inlet pipe, and big air inlet pipe ledge is closely linked to each other by laggard hermetic seal piston with little air inlet pipe.The expiration EGR changes fan, little blast pipe, heat-insulating flame-retardant casket, supply unit, front exhaust packed-piston, middle exhaust sealing piston, proof and electric leakage-proof safety casket, lead, final vacuum packed-piston by exhaust active carbon filtering device, motor, big blast pipe, exhaust and forms; Closely be connected by the front exhaust packed-piston between exhaust active carbon filtering device and the big blast pipe; There is exhaust to change fan in the big blast pipe; Motor is equipped with the heat-insulating flame-retardant casket outward; Link to each other with lead between motor and the power supply; Supply unit is equipped with the proof and electric leakage-proof safety casket outward, is closely linked to each other by middle exhaust sealing piston between lead and the big blast pipe, and big blast pipe ledge is closely linked to each other by the final vacuum packed-piston with little blast pipe.The head dust guard is made up of nostril getter device, mouthful exhaust apparatus, mask main body, mouth mask static line four parts; The mouth mask static line is symmetrically distributed in the mouth mask both sides; Closely be connected through the air inlet packed-piston between nostril getter device and the little air inlet pipe, a mouthful breath device closely is connected through the expiration packed-piston with little blast pipe.
During use, at first mask main body is fixed to head through the mouth mask static line, inhalation cycle device, expiration EGR are worn on the waistband through the belt clip; Open that fan power supply device switch is changed in air inlet and fan power supply device switch is changed in exhaust, air gets into big air inlet pipe from the air inlet active carbon filtering device, and air inlet is changed fan and quickened circulation of air; Air gets into the nostril getter device through little air inlet pipe; Thereby the entering human body, the gas that the people breathes out is the inlet port breath device then, through little blast pipe; Get into big blast pipe; The circulation that fan quickens to discharge air is changed in exhaust, and gas enters atmosphere through the exhaust active carbon filtering device, realizes that wind dustproof purpose is changed in the circulation of air inlet expiration.
Beneficial effect
One, simple in structure, convenient and practical.
Two, with low cost, be easy to promote.
Three, can effectively alleviate the workman's head load and the interior sultry problem of anti-dust respirator of carrying dust guard pollution abatement equipment for a long time.
