Description

The face mask type breathing equipment
(1) technical field
The utility model relates to a kind of breathing equipment.Be the face mask type breathing equipment that can use simultaneously for many people specifically.Speedily carry out rescue work and the occasion of chemical leakage and anoxic in the down-hole that is applicable to fire fighting, mine.
(2) background technology
As everyone knows, speedily carry out rescue work in the down-hole in fire fighting, mine and pernicious gas such as chemical leakage pollutes and the occasion of anoxic, personnel must wear breathing equipment, the required oxygen of existence to be provided and to remove the carbon dioxide of breathing out simultaneously.Traditional breathing equipment mainly contains chemical oxygen supply and physics oxygen supply dual mode.As the fire-fighting fire extinguishing breathing mask, its oxygen supply mode is chemical oxygen supply, and its with medicament is sodium superoxide, potassium superoxide etc.Because super oxidation medicament is easily gelatinization, bonding in course of reaction, its performance is subjected to the influence of environment temperature, humidity bigger, so the support time of this class breathing equipment is shorter, has only 20~40 minutes usually.
The respirator that the personnel that speedily carry out rescue work under the coal mine for another example use, its oxygen supply mode is the physics oxygen supply.Wherein, institute's with medicament is the carbon-dioxide absorbent of soda lime, NaOH and so on.Because the efficient of this carbon-dioxide absorbent is subjected to the breathe out influence of steam of user bigger, the time that therefore this respirator is supported is not long yet, is no more than 4 hours usually.
In addition, breathing equipment all is single outfit in above-mentioned two, can not use simultaneously for many people, and the scope of application is restricted.
(3) utility model content
The technical problems to be solved in the utility model provides a kind of face mask type breathing equipment.This breathing equipment, not only the time of supporting is grown, can use simultaneously for many people, and the scope of application is wider.
For addressing the above problem, the utility model is taked following technical scheme:
Face mask type breathing equipment of the present utility model comprises gas supply mechanism, oxygen supply mechanism, breathing bag and face shield.Said gas supply mechanism is made up of air bottle, air valve, air manometer, air pressure reducer, air control shutter and air cutoff valve, and the gas outlet of air bottle is connected with breathing bag by air valve, air pressure reducer, air control shutter air cutoff valve and pipeline successively.Said oxygen supply mechanism is made up of oxygen cylinder, oxygen gauge, oxygen valve, oxygen pressure reducer, oxygen choke valve and oxygen valve for pressure difference, the gas outlet of oxygen cylinder divides two-way to be connected with breathing bag by oxygen choke valve and oxygen valve for pressure difference respectively by oxygen valve, oxygen pressure reducer with after pipeline links to each other successively again, and oxygen gauge is connected on the pipeline between oxygen valve and the oxygen spare depressor.Be characterized in that said face shield has several, these several face shields are connected with breathing bag and carboloy dioxide canister by air intake duct and exhaust tube respectively.Carboloy dioxide canister wherein communicates with breathing bag and some face shields respectively, and carbon-dioxide absorbent is arranged in it, and dewatering outlet and discharging valve are arranged at its bottom.Said carbon-dioxide absorbent is the lithium hydroxide absorbent.
Adopt such scheme, have the following advantages:
Because face mask type breathing equipment of the present utility model, its face shield has several, and these several face shields are connected with breathing bag 9 and carboloy dioxide canister 11 by air intake duct 18 and exhaust tube 19 respectively, under pernicious gas or anoxic environment, can use simultaneously for many people, the scope of application is wider.
Owing to face mask type breathing equipment of the present utility model, its used carbon-dioxide absorbent is the lithium hydroxide absorbent again, the absorption efficiency height, and the time of support is long.Through on probation, face mask type breathing equipment three people of the present utility model use simultaneously, can support more than 12 hours, are 2~3 times that traditional breathing equipment is supported the time.
(4) description of drawings
Accompanying drawing is a face mask type breathing equipment structural representation of the present utility model.
(5) specific embodiment
As shown in drawings, face mask type breathing equipment of the present utility model comprises gas supply mechanism, oxygen supply mechanism, breathing bag 9 and face shield 20.Said gas supply mechanism is made up of air bottle 3, air valve 4, air manometer 5, air pressure reducer 6, air control shutter 7 and air cutoff valve 8, and the gas outlet of air bottle 3 is connected with breathing bag 9 by air valve 4, air pressure reducer 6, air control shutter 7 air cutoff valves 8 and pipeline successively.On the breathing bag 9 wherein safety valve 10 is housed.Said oxygen supply mechanism is made up of oxygen cylinder 13, oxygen gauge 2, oxygen valve 12, oxygen pressure reducer 14, oxygen choke valve 15 and oxygen valve for pressure difference 16, the gas outlet of oxygen cylinder 13 is connected with breathing bag 9 by oxygen choke valve 15 and 16 fens two-way of oxygen valve for pressure difference respectively by oxygen valve 12, oxygen pressure reducer 14 with after pipeline links to each other successively again, oxygen gauge 2 is connected on the pipeline between oxygen valve 12 and the oxygen spare depressor 14, on the pipeline that oxygen gauge 2 and oxygen valve are 12 oxygen fill valve 1 is installed.Said face shield 20 has three, and these three face shields are connected with breathing bag 9 and carboloy dioxide canister 11 by air intake duct 18 and exhaust tube 19 respectively.Carboloy dioxide canister wherein communicates with breathing bag 9 and some face shields 20 respectively, and carbon-dioxide absorbent is arranged in it, and dewatering outlet and discharging valve 17 are arranged at its bottom.Carbon-dioxide absorbent wherein is the lithium hydroxide absorbent.
During use, open the air valve 4 in the gas supply mechanism earlier, pressure-air becomes low-pressure air after air pressure reducer 6 decompressions.This low-pressure air enters breathing bag 9 by air control shutter 7 with certain flow, makes breathing bag 9 full, as the carrier of closed circulatory and respiratory.Close air cutoff valve 8 then, open oxygen cylinder 13 and oxygen valve 12, and note observing oxygen gauge 2, make oxygen enter gas supply mechanism.High pressure oxygen is after oxygen pressure reducer 14 decompressions, and the one road is the oxygen of breathing bag 9 supplement consumed through oxygen choke valve 15 with the flow of setting.If quantitatively the oxygen that replenishes is less than consumption, the pressure in the breathing bag 9 is descended.When dropping to a certain amount of value, the oxygen valve for pressure difference 16 on another road can be opened automatically, and breathing bag 9 is carried out instantaneous big flow oxygenating, thereby pressure in the breathing bag 9 is risen and closes oxygen valve for pressure difference 16 automatically, finishes automatic control oxygenating by inferior.Personnel put on face shield 20, suck by air intake duct 18 and breathe the oxygen of wearing in 9.And the gas of breathing out enters carboloy dioxide canister 11 through exhaust tube 19, by the absorbent in the carboloy dioxide canister 11 with carbon dioxide absorption and by activated carbon to gas purify remove peculiar smell after, enter again in the breathing bag 9 for recycling.Safety valve 10 wherein is for preventing that the hypertonia in the breathing bag 9 from establishing.
