The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, this isolation type compressed oxygen self-rescuer, comprises the high-pressure system, respiratory system and the CO that are arranged in housing
2filtration system; Described high-pressure system comprises oxygen cylinder 1 and pressure-reducing valve 3; Described respiratory system comprises mouthful tool 6, air bag 8, air bleeding valve and breather valve; The outlet of described oxygen cylinder 1 is connected to the oxygen intake of air bag 8 by pressure-reducing valve 3 and tracheae, the gas outlet of described air bag 8 is connected to the air inlet of mouthful tool 6 by tracheae and inlet valve; The gas outlet of described mouthful of tool is connected in peace and quiet tank 12 by tracheae and outlet valve, and the exhaust outlet of described peace and quiet tank 12 is connected in air bag 8 by tracheae; Described air bag 8 is also provided with exhaust outlet, and the exhaust outlet of air bag 8 is connected with air bleeding valve by tracheae; In described peace and quiet tank 12, CO is housed
2absorbent.On the outlet tracheae of described oxygen cylinder 1, be also provided with Pressure gauge.The gas outlet of pressure-reducing valve also separates a bronchus and is connected to by hand-operated valve the air inlet of air bag.Pressure-reducing valve is also connected with safety valve.On oxygen cylinder 1, be provided with gas cylinder switch 2.
The orthogonal structure of described housing, is made up of lower tank 10 and upper cover 13, is divided into two chambers in left and right in lower tank 10, and peace and quiet tank 12 is installed by left chamber, and right chamber is installed oxygen cylinder 1; The top right side of described upper cover 13 is provided with oxygen gauge observation window 5, at the top of oxygen cylinder 1, Pressure gauge 4 is installed, and this Pressure gauge 4 can see through oxygen gauge observation window 5 and observe.The both sides of lower tank 10 are provided with braces.The medial surface of lower tank 10 is provided with strap lug 16.On upper cover 13, be also provided with rubber protecting band 15.
This device at ordinary times all systems is all contained among housing, and user can be clear that by the oxygen gauge observation window 5 on upper cover 13 the pressure indication of Pressure gauge 4.On lower casing, be provided with punch holes and braces, user can be fixed on miner's belt or carry on the arm piggyback.
Operation principle of the present utility model is as follows:
Rotate counterclockwise gas cylinder switch 2, it is interior after decompression that high pressure oxygen just flows to pressure-reducing valve 3 from oxygen cylinder 1, and the oxygen of automatically exporting 1.2L/min enters air bag 8.The tonifying Qi pressing plate 9 that press...withes one's finger, oxygen enters air bag 8 with 60L/min, and hand leaves tonifying Qi pressing plate 9, and oxygenating stops.
This product also has automatic oxygen supplement function, and in the time that respiratory system is negative pressure, tonifying Qi pressing plate 9 inwardly shrinks, compressing tonifying Qi bar (in air bag) is opened oxygenating mechanism, and oxygen is filled with air bag with 60L/min, in the time that air bag is heaved, tonifying Qi pressing plate 9 leaves tonifying Qi bar, and tonifying Qi stops.If the air pressure in respiratory system exceedes certain value, gas will overflow from air bleeding valve.
When air-breathing, oxygen is from air bag 8, and inlet valve, a mouthful tool 6 enter human body.When expiration, gas is through breather valve, and the expiration flexible pipe in air bag enters peace and quiet tank 12, the CO of characteristics of contaminated respiratory droplets
2absorbed by the in-built absorbent of peace and quiet tank 12, remaining oxygen enters air bag 8.So repeatedly complete people's breath cycle.The breathing of human body and ambient atmosphere are completely isolated.The gas-storing capacity of oxygen cylinder 1 interior oxygen is shown by Pressure gauge 4.
The utility model is mainly used in having the ore deposit underground rescue protection of coal and Gas Outburst.The machine air way that it is arranged on chamber under coal mine or coal-face enters appropriate location or the more place of mobile personnel of head, and the ground such as scraper-trough conveyer head, shaft station, transportation and return aircourse, various stations.When fall of ground occurs, when coal and Gas Outburst or while having outstanding omen, staff running enters the place and the place that are attached with respirator and keeps away calamity, puts on respirator, waits for rescue.It is the lifesaving breathing equipment that down-hole is welcome by miner very.
