Abstract
The utility model discloses an air-curtain type dustproof miner cap which comprises a cap body, a lining cap and a lamp carrier, wherein the lining cap is arranged at the inner side of the cap body, and the lamp carrier is arranged at the front side of the cap body; the front part of the cap body is a double-layer structure with a gap layer in the middle; the gap layer is connected with an air-curtain nozzle and an air inlet of an air intake nozzle respectively; the air intake nozzle is arranged at the top part of the cap body; and the air-curtain nozzle is arranged at the lower edge of the front part of the cap body. The air-curtain type dustproof miner cap has reasonable design and simple structure, uses compressed-air of an essential compressed-air self-rescue system in a coal mine shaft as the air source, achieves the dustproof purpose of miner individuals in an air-curtain way, has low cost, does not affect respiration and is convenient to use.
Description
Technical field
The utility model relates to the papermaking equipment technical field, is specifically related to the dustproof miners' cap of a kind of air-curtain type.
Background technology
Existing miners' cap has the protective effect to human body head, can prevent that head from being pounded by rock or other object or damage, but not possess protective action for the dust pollution in the mine.Usually contain a large amount of dust in the air of miner job site, when the dust that sucks lung as the miner reaches some, will cause that fibrosis lesion takes place in lung tissue, lung tissue is hardened gradually, thereby lose normal respiratory function, pneumoconiosis takes place.By the end of the year in 2005, the number of patients of state's troubles pneumoconiosis added up to surpass 600,000 people, dead 170,000 people.Annual newly-increased people up to ten thousand.In global pneumoconiosis patient, Chinese number of patients accounts for half, and wherein, coal miner has just accounted for half.
In order to prevent dust harzard, people have developed multiple anti-dust respirator and air-curtain type protective face mask.Owing to uses mouth mask can increase respiratory resistance, and make the perspire difficulty, so down-hole miner seldom uses.The air-curtain type protective face mask is made up of parts such as blast pipe, control valve, waistband, filter, pressure-reducing valve, firm banking, head hoop, wind-distributing pipe and transparent face masks, the compressed air of being sent by source of the gas enters wind-distributing pipe behind pressure-reducing valve, filter and control valve, be positioned at part lower end, head hoop the place ahead at wind-distributing pipe and have a row or multi-row intensive hole, when gas during from the ejection of this hole, will form air curtain in the transparent face mask both sides, the air curtain of transparent face mask inboard is available for users to breathe usefulness, and the air curtain in the outside can be isolated dust or the toxic gas that flies upward.It is big that above-mentioned air-curtain type protective face mask system complex, individuality are carried weight, and transparent face mask pollutes easily, hinders miner's sight line, influences operation.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of air-curtain type reasonable in design, simple in structure, easy to use, that protection effect is good dustproof miners' cap.It directly is connected with calm the anger the calming the anger of air feed system of saving oneself of mine by suction nozzle, air hose, calm the anger by the air curtain of dustproof miners' cap formation around human body face, the pollution of isolated rear portion dust of cloth curtain mode or dust laden air is adopted at the dustproof miners' cap rear portion of air-curtain type.
The technical solution of the utility model is: a kind of air-curtain type miners' cap that prevents dust, comprise the cap body, be arranged on the lining cap of cap body inboard and be arranged on the lamp socket of cap body front side, it is characterized in that: the front portion of cap body is the middle double-decker that is provided with void layer, void layer is connected with the air inlet of air curtain spout and suction nozzle respectively, suction nozzle is arranged on the top of cap body, and the air curtain spout is arranged on the lower edge of cap body front portion.
Above-mentioned a kind of air-curtain type miners' cap that prevents dust is characterized in that: be that the center radially is provided with many air guide parting beads with the air inlet in void layer.
Above-mentioned a kind of air-curtain type miners' cap that prevents dust, it is characterized in that: the rear portion of cap body is provided with the screening dust cloth curtain.
The utility model compared with prior art has the following advantages:
The utility model is reasonable in design, and is simple in structure, utilizes under the coal mine calming the anger as source of the gas of the indispensable system of saving oneself of calming the anger, and reaches the individual dustproof purpose of miner in the mode of air curtain, be a kind of cost low, do not influence breathing, dustproof miners' cap easy to use.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
As shown in Figure 1, the utility model comprises cap body 1, be arranged on the lining cap 2 of cap body 1 inboard and be arranged on the lamp socket 3 of cap body 1 front side, the front portion of cap body 1 is the middle double-decker that is provided with void layer 4, void layer 4 is connected with the air inlet 7 of air curtain spout 6 and suction nozzle 5 respectively, suction nozzle 5 is arranged on the top of cap body 1, and air curtain spout 6 is arranged on the lower edge of cap body 1 front portion.
For the rear portion of cap body 1 is effectively protected, the rear portion of described cap body 1 is provided with screening dust cloth curtain 9.
As shown in Figure 2, evenly flowing through in void layer 4 for making gas, is that the center radially is provided with many air guide parting beads 8 that are used for air guide with air inlet 7 in void layer 4.
During the utility model work, the calming the anger of the system of saving oneself of the calming the anger suction nozzle 5 that is connected by air hose and with air hose enters in the void layer 4 of cap body 1 front portion, the floor height of void layer 4 is less than 0.5mm, enter calming the anger under the guiding of air guide parting bead 8 in the void layer 4, spread to the air curtain spout 6 that is arranged on cap body 1 anterior lower edge equably along void layer 4, and by air curtain spout 6 ejection formation air curtain, air curtain is isolated with the dust of down-hole and staff's mouth and nose.The screening dust cloth curtain 9 that is arranged on cap body 1 rear portion can stop the pollution of dust to staff's neck rear portion.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of technical solutions of the utility model according to the utility model technical spirit.
