Description

A kind of new type mining isolation type chemical-oxygen self-rescuer

(1) technical field

The utility model patent relates to a kind of new type mining isolation type chemical-oxygen self-rescuer.

(2) background technology

According to the regulation of China's " safety regulations in coal mine ", the personnel gone into the well in every colliery should carry self-rescuer and go into the well, and when dangerous situation appears in underground coal mine generation major accident, the personnel of going into the well should open immediately and wear self-rescuer and to escape danger escape.Isolation type chemical-oxygen self-rescuer is the mining self-rescuer of one that each colliery of China comparatively generally uses, although this kind of self-rescuer exists more advantage, also there is a little shortcoming being badly in need of improving.Potassium superoxide oxygen generating agent in this kind of self-rescuer generate oxygen time need steam to participate in, and emergency escape personnel just worn this kind of self-rescuer escape danger escape time, steam of also not breathing out in the mouth, potassium superoxide also just can not generate oxygen staff breathing.For addressing this problem, be just provided with in this kind of self-rescuer just wear self-rescuer escape danger escape time just can discharge the initial stage oxygen generator of a small amount of oxygen.Present initial stage oxygen generator has the three types such as sulfuric acid bottle, oxygen candle, little oxygen tank, but the initial stage oxygen generator of this three types all also exists the different shortcoming of degree and hidden danger, so that can not produce oxygen, trouble is caused for personnel wear self-rescuer escape of escaping danger, originally be help device, instead likely become device of getting killed; For many years, all there is the example that this class causes casualties in each colliery of China.Thus, researching and developing novel initial stage oxygen generator or its replacement device makes the function of such mining self-rescuer more improve the research direction becoming related scientific research personnel.

(3) utility model content

The object of the utility model patent also exists more hidden danger for solving existing three kinds of initial stage oxygen generators, cause isolation type chemical-oxygen self-rescuer can not be a difficult problem for emergency escape personnel normal supply oxygen, provide a kind of hydrophilic catalyst catalytic convention design of alternative three kinds of initial stage oxygen generators as novel initial stage oxygen generator, be assembled in mining isolation type chemical-oxygen self-rescuer, thus be born and the mining isolation type chemical-oxygen self-rescuer of latest generation.

The utility model patent is achieved through the following technical solutions:

A kind of new type mining isolation type chemical-oxygen self-rescuer; it is under all immovable prerequisite of existing various mining isolation type chemical-oxygen self-rescuer basic structures; instead of existing three kinds of initial stage oxygen generators with a kind of hydrophilic catalyst catalytic convention design; as a kind of novel initial stage oxygen generator, it is escaped danger for underground coal mine and is supplied to the oxygen of a certain amount of respiratory protection effect time escape personnel has just worn and used self-rescuer.Structure and the technical characteristic of this new type mining isolation type chemical-oxygen self-rescuer are: the initial stage oxygen generator of mining isolation type chemical-oxygen self-rescuer inside forms with stay cord, stopper, screen layer, container, hydrophilic catalyst, container outlet side structure, one end of described stay cord is fixed on oxygen generator top, the other end of stay cord is fixed on stopper, described stay cord and stopper are exposed to the top of oxygen generator, and the other parts of initial stage oxygen generator are deeply buried in the inside of oxygen generator, thus textural association becomes new type mining isolation type chemical-oxygen self-rescuer.

Described catalyst, it can become nontoxic carbon dioxide monoxide conversion poisonous in air; Described hydrophilic catalyst is the new catalyst that domestic and international market just occurs in recent years, and he is not afraid of the invasion of steam, and had the intervention of certain steam, it to the changing effect of carbon monoxide better; And catalyst before this, can be described as again after " hydrophobicity catalyst " this kind of catalyst runs into the invasion of steam, catalyzed conversion effect can progressively reduce and even thoroughly lose efficacy.

Described container, it is the carrier of hydrophilic catalyst, stopper, screen layer, stay cord, after assembling screen layer, hydrophilic catalyst, stopper, stay cord, is generically and collectively referred to as hydrophilic catalyst catalytic convention design, also can be referred to as novel initial stage oxygen generator.

The screen layer at described container two ends, arranges the object of screen layer, is for preventing hydrophilic catalyst from leaking outside away.

Described stopper, when new type mining isolation type chemical-oxygen self-rescuer product is in factory-assembled, just tight for the container blocking of filling hydrophilic catalyst, only have and to escape danger escape when coal mine down-hole personnel is in danger, when opening and wear self-rescuer, open stopper immediately, first the outside air after by hydrophilic catalyst catalyzed conversion is breathed, carbon monoxide now in outside air is become carbon dioxide to health fanout free region by hydrophilic catalyst catalyzed conversion substantially, when personnel have breathed two, after three mouthfuls of outside airs, oxygen generator is entered into regard to the steam had from breathing out in the mouth, pure oxygen will be generated after potassium superoxide oxygen generating agent in oxygen generator touches steam thereupon, when finding the inlet end that immediately stopper should be blocked up again tight container after air bag is full of by gas, now, human body and isolation type chemical-oxygen self-rescuer are just organically combined into closed circuit circulatory system, the personnel that ensure escape danger escape.

Described hydrophilic catalyst catalytic convention design and stopper, also have two important effects, the first when air bag is flat go down after, show that the potassium superoxide oxygen generating agent in oxygen generator is exhausted substantially, now also can open stopper, support personnel's eupnea is successfully escaped danger escape; It two is after gas expansion in air bag is full, in time opens stopper and makes the gas of exhalation discharged to jam-pack stopper Here it is usually said " being vented in advance " function again behind the external world.

Described stay cord, one end is fixed on oxygen generator, and the other end is fixed on stopper, avoids in use stopper to lose.

The beneficial effects of the utility model are: in the utility model, existing initial stage oxygen generator is instead of with hydrophilic catalyst catalytic convention design, novel initial stage oxygen generator overcomes the potential safety hazard solving existing initial stage oxygen generator and likely exist, thus provides the mining isolation type chemical-oxygen self-rescuer of latest generation; The novel isolation type chemical-oxygen self-rescuer that have employed novel initial stage oxygen generator also has the advantages such as temperature in oxygen generator is low, advanced degassing function.

Below in conjunction with accompanying drawing, the utility model is further described.

Accompanying drawing 1 is the complete machine structure outside drawing of various isolation type chemical-oxygen self-rescuer, and this is prior art;

Accompanying drawing 2 is for opening the cut-away view of the isolation type chemical-oxygen self-rescuer after upper shell, and this figure is also as Figure of abstract;

Accompanying drawing 3 is hydrophilic catalyst catalytic convention design is also novel initial stage oxygen generator structure chart;

In accompanying drawing: on 1 lower casing 2, shell 3 nose clip group 4 mouthpiece group 5 breathing hose 6 is breathed air valve group 7 air bag 8 air bleeding valve 9 and to be exhaled conduit 10 initial stage oxygen generator 11 potassium superoxide oxygen generating agent 12 oxygen generator 13 stay cord 14 stopper 15 screen layer 16 container 17 hydrophilic catalyst 18 container outlet side.

(5) detailed description of the invention

Hydrophilic catalyst catalytic convention design had just assembled before the novel isolation type chemical-oxygen self-rescuer complete machine of assembling in advance as a vitals of novel isolation type chemical-oxygen self-rescuer as shown in Figure 3.Process or the step of assembling hydrophilic catalyst catalytic convention design fill full hydrophilic catalyst 17 after a screen layer 15 first put into by 16 li, stamping forming container, put a screen layer 15 on hydrophilic catalyst 17 after, jam-pack stopper 14 just can wait for that isolation type chemical-oxygen self-rescuer complete machine assembles.

When assembling novel isolation type chemical-oxygen self-rescuer complete machine, other assembly technology is consistent with the assembly technology of existing isolation type chemical-oxygen self-rescuer, only have the packaging technology of initial stage oxygen generator slightly different, its packaging technology process is: the overwhelming majority of the hydrophilic catalyst catalytic convention design assembled in advance is all put in oxygen generator 12 by the tapping of oxygen generator 12 top, and the junction scolding tin of hydrophily catalytic convention design and oxygen generator 12 or binding agent etc. are bondd firmly, gap must not be had, stay cord 13 is connected fastening with oxygen generator 12.

When underground coal mine generation serious disasters and accidents, hedging escape personnel wears to use novel isolation type chemical-oxygen self-rescuer and wear and uses the method for existing mining isolation type chemical-oxygen self-rescuer also substantially consistent, only wear and use the method for new type mining isolation type chemical-oxygen self-rescuer more simple and convenient, and the survival time in tens seconds can be saved; When personnel escape danger escape, open the upper shell 2 of self-rescuer and throw away it, clamping nose by nose clip group 3, unpluging the stopper 14 in hydrophilic catalyst catalytic convention design, stinging the mouthpiece group 4 on tight air bag 7, just can escape danger and escape.Now first inspiration be gas in external environment, now a certain amount of carbon monoxide and carbon dioxide may be contained in the air of extraneous bad border, but the hydrophilic catalyst 17 in hydrophilic catalyst catalytic convention design can become carbon dioxide these monoxide conversion, and the potassium superoxide oxygen generating agent 11 in oxygen generator 12 can become oxygen carbon dioxide conversion, ensure that personnel's inspiration gas is in the mouth pure oxygen; After two or three mouthful of outside ambient air is breathed out again in personnel's inspiration, the steam of breathing out in the mouth just can produce chemical reaction with the potassium superoxide oxygen generating agent 11 of oxygen generator 12 li and automatically generate oxygen, now just can stopper 14 jam-pack on container 16, make people and self-rescuer organic structure become the closed cycle respiratory system be isolated with outside air, now the mission of hydrophilic catalyst catalytic convention design just completes.On hedging escape road, the respiratory system in human body and novel isolation type chemical-oxygen self-rescuer organic structure become the closed cycle respiratory system be isolated with outside air, and being provides oxygen support personnel smooth hedging escape like this; The gas of namely breathing out in personnel's mouth is the bottom being entered into oxygen generator 12 by the outlet valve in mouthpiece group 4, breathing hose 5, breathing air valve group 6, expiration conduit 9; The gas entered into bottom oxygen generator 12 can spread to rise to again and enter air bag 7 in potassium superoxide oxygen generating agent 11 medicine layer, when through potassium superoxide oxygen generating agent 11 medicine layer, steam in gas and carbon dioxide will produce chemical reaction with potassium superoxide oxygen generating agent 11, produce oxygen, so the gas major part entering into air bag 7 is oxygen, also has a small amount of carbon dioxide; When personnel's air-breathing, the oxygen in air bag 7 will by breathing inlet valve in air valve group 6 and breathing hose 5, mouthpiece group 4 enters into personnel's mouth and lung; In whole respiratory, because nose is clamped by nose clip group 3, again because the stopper 14 in hydrophilic catalyst catalytic convention design is also container 16 jam-pack, respiratory system in old friend's body and novel isolation type chemical-oxygen self-rescuer just organically structure become the closed cycle respiratory system be isolated with outside air, ensure personnel's successfully hedging escape.Two important effects can also be played in the road that hydrophilic catalyst catalytic convention design is escaped at hedging, the first is when gas expansion in air bag 7 is full, can open stopper 14 makes the air release of exhalation go to the external world, to breathe out after several mouthfuls jam-pack stopper 14 again, this, be usually said " being vented in advance " function, in personnel's mouth, in breath, carbon dioxide content is more, and it is to save much oxygen that advance exhaust is gone out than the advantage of being discharged by air bleeding valve 8; Its two be hedging escape road on, personnel also do not arrive safe place, and potassium superoxide oxygen generating agent 11 has been finished release does not go out oxygen and cause that air bag 7 is flat to have got off, at this moment opens stopper 14 and breathed air in external environment, still support personnel can arrive safety zone.
