Description
Technical field
The utility model belongs to a kind of in pernicious gas environment, and user realizes the fail safe instrument of autoprotection.
Background technology
Locating Type chemical oxygen self-rescuer (hereinafter referred to as " self-rescuer ") is a kind of respirator completely cut off completely with ambient atmosphere; it is widely used in mine down-hole workman and is confined in disaster region; wait for rescue or directly flee from, realize the protection of self respiratory system around here.
It is high that the chemical oxygen self-rescuer ubiquity of current use suction temperature, and reach 55 ~ 60 DEG C, service time is short, the longest ability 60 minutes, is not suitable for person in distress high because of suction temperature, is difficult to stand and the loss of life because survival time is short; Only have a kind of 2 hours compressed oxygen respirators to be applied to down-hole refuge cabin or refuge chamber at present, this kind of respirator shortcoming is more, and one is that service time is short, treats that rescue time only has 120 minutes, and be nowhere near needs to be rescued; Two is that weight is too large, at least wants 7kg; Three is need to make regular check on, and oxygen cylinder is internal oxygen seepage sometimes, or Pressure gauge malfunctioning needs upgrades, and oxygen cylinder requires 3 years to want the water pressure test once, can use after qualified; Four is can not ensure positive confinement after CO2 absorbent loads finished product, and need upgrade once half a year, five is the person in distress using this product, has to pass through special training, otherwise can not reasonably operate.In sum, research and development a kind of survival time is long, and weight is relatively light, and suction temperature is low, substantially belongs to barotropic state, does not need scheduled maintenance inspection, does not need " the Locating Type chemical oxygen self-rescuer " of special training to be current problem anxious to be resolved.
Utility model content
The purpose of this utility model is to provide a kind of Locating Type chemical oxygen self-rescuer, leave refuge chamber, refuge cabin or operation field in, when person in distress is confined in disaster area, individual cannot self flee from, the time that waits for rescue just can reach 480 minutes or 720 minutes (two profiles number), is equivalent to the service time of 8 hours or 12 hours; Light weight, at about 3.5kg or 4kg; Comfortable suction temperature, does not the highlyest surpass 40 DEG C; Without the need to periodic inspection and maintenance; The oxygen generating agent term of validity can for 10 years; User does not need special training, as long as the operating instruction having a look appearance at ordinary times can be carried out proper use of.
The purpose of this utility model is achieved by the following scheme: it comprises mouthpiece, inlet valve, outlet valve, inhaling hose, expiration flexible pipe, starting drive, air bag, cooler assembly, oxygen generator assembly, it is characterized in that: at the tank body of cooler assembly built with heat-exchange corrugated pipe, heat-exchange corrugated pipe is spiral-shaped, spiral-shaped centre arranges phase-changing energy storage material bag, and the two ends of heat-exchange corrugated pipe connect inhaling hose, expiration flexible pipe respectively.
The tank body of above-mentioned oxygen generator assembly adopts columnar structured, and upper end, lower end arrange air inlet end cap respectively, end cap of giving vent to anger.
The tank body of above-mentioned cooler assembly adopts columnar structured, and upper end, lower end arrange end cap respectively.
Effect of the present utility model is: 1. select chlorate oxygen candle starting drive, safe and reliable; 2. oxygen generator adopts circular tube structure, and reduce medicament dead angle, sufficient reacting, improves the utilization rate of oxygen generating agent; 3. chemical reaction is mild, and the levelling that produces oxygen is steady, and relative temperature is lower, and the utilization rate on self-rescuer is higher, obviously extends working time, can for 10 years under air-proof condition; 4.Heat-exchange corrugated pipe is adopted at cooler assembly, heat-exchange corrugated pipe is helical disk dress shape, and intermediate space arranges phase-changing energy storage material, the composite structure that bellows combines with phase-changing energy storage material, achieve good dual cooling-down effect, can guarantee that suction temperature is below 40 DEG C.Survival time, significant prolongation was to normal escape time about 4 times
.

Detailed description of the invention
See Fig. 1 ~ 3, concrete structure is as follows: adopt existing product structure to carry out following assembling: to arrange mouthpiece 6, mouthpiece 6 is arranged inlet valve 7 and outlet valve 5; Oxygen generator assembly 2, cooler assembly 11 and air bag 9 is assembled in the housing that band is carried in connection on the arm; The inlet valve 7 of mouthpiece 6 connects air bag 9 by inhaling hose 8-1, and air bag 9 connects cooler assembly 11 by inhaling hose 8-2; Air bag 9 is arranged air bleeding valve 10; The outlet valve 5 of mouthpiece 6 connects the oxygen candle starting drive 3 of oxygen generator body 2-3 upper end by expiration flexible pipe 4-1, oxygen candle starting drive 3 is chlorate oxygen candle starting drive, oxygen candle starting drive 3 is arranged and draws pin 3-1.The technical essential improved is: oxygen generator body 2-3 is built with the KO2 oxygen generating agent 2-4 of market sale; The upper end of angry tank body 2-3, lower end arranges air inlet end cap 2-1 respectively, give vent to anger end cap 2-5, assembles filter bar grid net 2-2,2-6 respectively, arrange filter cotton in filter bar grid net in the inner side of upper and lower end cap; The tank body 11-4 of cooler assembly 11 cylindrically, at tank body 11-4 built with heat-exchange corrugated pipe 11-3, heat-exchange corrugated pipe 11-3 is helical disk dress shape, arrange phase-changing energy storage material 11-2 in the intermediate space of helical disk dress shape, phase-changing energy storage material 11-2 adopts GR42 graininess phase-changing energy storage material (sale of Rule, Hangzhou Energy Science Co., Ltd); Phase-changing energy storage material 11-2 can be contained in polybag, and the two ends of heat-exchange corrugated pipe 11-3 connect inhaling hose 8-2, expiration flexible pipe 4-2 respectively.The tank body 11-4 upper end of cooler assembly, lower end arrange end cap 11-1 respectively, with the heat-exchange corrugated pipe of ease of assembly and phase-changing energy storage material.Upper and lower side between oxygen generator assembly 2 and cooler assembly 11 arranges desiccant bag 1.
Above-mentioned breathing hose, mouthpiece etc. adopt and can tolerate the fire-resistant antistatic of 8 years terms of validity silicon rubber ageing-resistant again, and air bag adopts fire-retardant TPU material, and oxygen generator and cooler casing all adopt stainless steel to make.
Operation principle: the person of saving oneself is containing biting mouthpiece, then the pin that draws pulled out on starting device starts air feed, start to breathe, the gas of breathing out enters oxygen generator absorption CO2 through expiration flexible pipe 4-1 and starts raw oxygen simultaneously, oxygen flow through expiration flexible pipe 4-2, cooler assembly, inhaling hose 1, band air bleeding valve air bag 9, inhaling hose 8-2, enter mouthpiece 6 and sucked by user, complete whole closed circuit breath cycle, repeatedly go on successively.CO2 and the H2O(aqueous vapor of breathing out in respiratory) and KO2 reaction, CO2 is absorbed, and O2 generates in a large number, and along with repeatedly carrying out of breathing, CO2 is constantly absorbed, and O2 constantly produces, and achieves user in disaster area and wins valuable escape time.
