Abstract
The invention discloses a kind of dust-proof mask with blower ventilation, it is by rubber jacket, filtering net box, the mouth of arranging, hold one's breath, and on the common anti-dust respirator of rope band, increases a plastics air duct and a miniature explosion-proof blower fan.Make air replacing in the mouth mask with pump drainage gas mode, eliminate the phenomenon of feeling oppressed, reach dustproof purpose, simple in structure, be the bigger cement plant of dust, coal miner good dust-proof apparatus.
Description
The present invention relates to a kind of anti-dust respirator of dustproof use, particularly a kind of dust-proof mask with blower ventilation.
Existing anti-dust respirator mainly is made up of rubber jacket, filter net sheet, exhaust outlet, rope band, what factories and miness used is exactly the anti-dust respirator of this form, this anti-dust respirator is to utilize people's breathing to make air through filtering, and exhaust outlet is discharged a part of gas, realizes dustproof.This anti-dust respirator weak point is in the thin place of roadway air oxygen content and the bigger occasion of dust causes expiratory dyspnea when using, the carbon dioxide that adds exhalation can not all be discharged mouth mask, repeat to suck lung, manual labor has increased respiratory capacity again and has caused expiratory dyspnea.Long-pending easily atomizing sweat in the mouth mask, the workman is reluctant to wear for a long time, makes the workman can not break away from the infringement of pneumoconiosis.
Order of the present invention ground is that a kind of improved anti-dust respirator will be provided, anti-dust respirator after the improvement is in the method by blower fan exhausting and air draft, air forms air replacing in the mouth mask through filtering, the atomizing sweat have been eliminated, this anti-dust respirator can make the workman normally wear at setting, give the generation of anti-pneumoconiosis, reach dustproof order ground.
Task of the present invention is finished as follows, makes triangle or the tetragonal outer cover that fastens the nose mouth with rubber or plastics, and 2 filtering net box that dwindle are arranged on the outer cover, and the filter course paper in the filtering net box increases thin sponge and filters dust.Paste the sponge bar that sponge bar or thin glue wrap on the outer cover, on outer cover, use plastics riveted rope band.In the mouth mask exhaust ports plastics air duct is installed, the plastics air duct is fixed a miniature explosion-proof blower fan with plastic interlayer, use the plastic cross frame air duct the bottom in, and rubber blanket is for holding one's breath, exhaust apparatus, and blower fan and air duct gap are the air channel, the external application guard shield screw thread installation of letting in air.Power supply: the mine lamp for mine power supply, be connected with mine lamp and can be stuck on the cap of ore deposit with a terminal box, terminal box adopts just pays utmost point pole on the charging rack, box behind portion adorns an iron plate card, by debuging whole voltage, guarantee the electricity consumption simultaneously of mine lamp blower fan in the box, adorn a flame-proof switch on the box.The small-sized storage battery of cement plant class, when mini fan pump drainage wind, the air that is filtered is discharged from the carbon dioxide of breathing out after being breathed by the people, has eliminated the atomizing sweat, has guaranteed that the air oxygen content in the mouth mask is consistent with the scene, reaches dustproof purpose.
Dust-proof mask with blower ventilation of the present invention has compared with prior art increased the amount of flow of air in the mouth mask, has eliminated and has breathed the phenomenon of feeling oppressed, atomizing sweat phenomenon.Create the condition that to wear for a long time, prevented to suffer from the factor of pounding tuberculosis effectively.Behind this launch products, can obtain good benefit.
Fig. 1 is the front view of dust-proof mask with blower ventilation of the present invention.
Fig. 2 is the A-A point profile of dust-proof mask with blower ventilation of the present invention.
Fig. 3 is the side view of dust-proof mask with blower ventilation terminal box of the present invention.
Below the present invention is described in further detail.
As shown in Figure 1: 2 plastic filtering net boxes (2) are arranged on rubber or the plastic housing (1) on outer cover. Make filter course with filter course paper and sponge in the box, lid fastens. Sponge bar (3) is bonded on the outer cover (1), and on outer cover (1), plastics air duct (5) is stuck on the outer cover (1) with ring-shaped groove rope band (4) with the plastics rivetings, during with plastic housing can with the air duct one-shot forming. In-built blower fan, ventilative guard shield (6) screw buckle is combined on the plastics air duct.
As shown in Figure 2: plastics air duct (5) has the fixedly movable installation of blower fan (12) interlayer of an interlayer (8), plastics air duct (5) and blower fan space are air channel (14), fire-proof motor and fan form blower fan (12), plastic cross frame (11) is installed in the blower fan bottom with sheet rubber (10), and protecting cover (9) has bar shaped or round vent (13) screw thread to fasten. (7) wire hole.
As shown in Figure 3: terminal box is made shell (15) with plastics or other material and is gone up installation anodal (16) and pay the utmost point (17) at shell (15), and iron card (18) links to each other with the ore deposit cap behind the lid.A peace flame-proof switch (19) on a side of box, line hole (20).
Embodiments of the invention, with former dustproof mouth mask repacking, as can be seen from Figure 1, producer only need manufacture the air duct parts and order blower fan and can implement.When adopting the change of outer cover form or with north material outer cover, brand-new manufacture technology is done by producer, implement not as repacking fast.
