Description
Technical field
The utility model relates to a kind of anti-dust respirator, and particularly a kind of powered supplied air anti-dust respirator is applicable to mine working, Hydraulic Tunnel, traffic tunnel, high dust work place.
Background technology:
Mine working, Hydraulic Tunnel, the contour dust work of traffic tunnel place can produce a large amount of dust when operation, the operating personnel can cause lung fibrosis after sucking for a long time dust.
The anti-dust respirator that uses in the dust at present working environment generally adopts from the respiratory face shield, and there are the following problems for this anti-dust respirator: (1) wears the after sensation expiratory dyspnea when labour intensity is larger, and face perspires and is difficult for discharging; (2) to the molecule of the naked eyes indistinguishables such as dust, coal dust, flue dust, dust-proof effect is poor; (3) sweat easily makes the filter paper in the anti-dust respirator lose efficacy and the reduction filter effect.
Summary of the invention
In order to improve the quality of dust work place operating personnel's air amount, the utility model provides the powered supplied air anti-dust respirator of a kind of comfortable wearing, convenience and filtration, good dustproof effect,
For achieving the above object, the solution that the utility model adopts is: this powered supplied air anti-dust respirator comprises face shield, wears rope, power supply, blower fan, filter cartridge and airduct, described face shield is provided with fresh air inlet, one end of airduct is connected in the fresh air inlet place of face shield, the other end is connected with filter cartridge, filter cartridge is installed on the air outlet place of blower fan, and power supply is connected with blower fan.
Be placed with the dustproof filter cloth of one deck technical grade in the above-mentioned filter cartridge.
Above-mentioned face shield is semi-enclosed annular silica gel face shield.
Above-mentioned power acquisition lithium ion battery.
Above-mentioned blower fan adopts centrifugal fan.
The utility model is worn on face shield on the face first when using, then power-on, drive blower fan, after the blower fan work workplace is contained in the air intake filter box of dust, behind the dustproof filter-cloth filtering of the technical grade in the box, pure air is entered in the face shield by airduct and breathes for the operation personnel after filtration.
The utlity model has following effect: (1) anti-dust performance is good, filter efficiency is high; (2) wind supply quantity is sufficient, and the staff wears rear smooth breathing; (3) simple in structure, wear conveniently.
