Utility model content
The purpose of this utility model is to provide a kind of malleation fresh air breather, and solving cannot be towards the individual technical problem that clean air is provided targetedly of work in dust atmosphere.
Malleation fresh air breather of the present utility model, comprise source of the gas three linked piece, wherein also comprise gas transmission manifold, air delivery valve, gas transmission connecting pipe and breathing mask, the air inlet of source of the gas three linked piece connects compressed-air actuated admission line, the gas outlet of source of the gas three linked piece connects the air inlet of gas transmission manifold by gas pipeline, gas transmission manifold is arranged on different lineman positions, connects respectively different air delivery valves at the gas transmission manifold of a lineman position, and air delivery valve connects breathing mask by gas transmission connecting pipe.
This device also comprises pneumatic pressure-release valve and after filter, each air delivery valve connects the air inlet of a pneumatic pressure-release valve by gas transmission connecting pipe, and the gas circuit in pneumatic pressure-release valve is connected after filter, and the gas outlet of pneumatic pressure-release valve connects the air inlet of breathing mask.
On described admission line, gate valve is set.
Malleation fresh air breather of the present utility model, simple in structure, handling good, safe and reliable.Can increase substantially operating efficiency, effectively reduce dust and suck, and can not cause local air concentration acute variation.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model malleation fresh air breather.
Detailed description of the invention
The compressed air that the present embodiment has utilized air compressing motor to produce, by source of the gas three linked piece, compressed air is carried out to first filtration and pressure regulation, and then utilize as much as possible gas circuit to distribute to the miner of field work compressed air, and utilize as required decompressor, filter on station to regulate compressed-air actuated pressure, flow and cleannes, breathe for miner.
As shown in Figure 1, the present embodiment comprise compressed-air actuated admission line, gate valve 01, source of the gas three linked piece 02, gas transmission manifold 03, air delivery valve 04, gas transmission connecting pipe 05, pneumatic pressure-release valve 06, after filter 07 and breathing mask 08.
Gate valve 01 is for regulating compressed-air actuated conveying total amount.
Source of the gas three linked piece 02 carries out constant voltage for the compressed air to a large amount of, filters, and filters out impurities, dust and aqueous vapor.
The pneumatic pressure-release valve 06 and compressed air being transported on station is carried out to secondary constant voltage after filter 07, filters, and filters out impurities, dust and aqueous vapor.
Gate valve 01 is set on admission line, admission line is fixedly connected with the air inlet of source of the gas three linked piece 02, the gas outlet of source of the gas three linked piece 02 connects the air inlet of gas transmission manifold 03 by gas pipeline, gas transmission manifold 03 is arranged on different lineman positions, gas transmission manifold 03 in a lineman position connects respectively different air delivery valve 04, each air delivery valve 04 connects the air inlet of a pneumatic pressure-release valve 06 by gas transmission connecting pipe 05, gas circuit in pneumatic pressure-release valve 06 is connected after filter 07, and the gas outlet of pneumatic pressure-release valve 06 connects the air inlet of breathing mask 08.
In practical application, for dust atmosphere, utilize gate valve 01 to regulate compressed air require, ensure enough compressed air pressure, utilize source of the gas three linked piece 02 to complete preliminary air constant voltage and filtration, gas transmission manifold 03 is connected to gas pipeline on corresponding station, utilize several air delivery valves 04 of being connected with gas transmission manifold 03 to provide the compressed air gas source of some for same station, the pneumatic pressure-release valve 06 that each air delivery valve 04 connects and can provide again the fresh and clean air of constant voltage and filtration for breathing for a miner's breathing mask 08 after filter 07.Each miner can regulate corresponding pneumatic pressure-release valve 06 as required, changes clean air flow, and the face shield 08 that ensures respiration remains malleation, avoids dust to suck, and can not change near the oxygen content in air of station simultaneously.
By source of the gas three linked piece 02 to compressed air deslagging, water suction, source of the gas three linked piece 02, pneumatic pressure-release valve 06 have been realized constant gas pushing quantity, pneumatic pressure-release valve 06 is provided with manual stable voltage mechanism, be provided with ponding eliminating mechanism after filter 07 and also can get rid of unnecessary aqueous vapor, self-absorbing filtering type face shield on operating location band, now self-absorbing filtering type face shield internal pressure is 0.05-0.1MPA, OFP air pressure is worth lower than this, face shield is inside and outside to be formed between zone of positive pressure, and dust can not enter into cover.
On the basis of above embodiment, pneumatic pressure-release valve 06 and can adopt cheap source of the gas bigeminy part or source of the gas three linked piece to replace after filter 07, to realize better air feed effect.
On the basis of above embodiment, also can on each air delivery valve 04, connect different gas equipments.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
