Abstract
The utility model relates to an isolation type compressed oxygen self-rescuer, which comprises an upper shell, a lower shell and a breathing mask set. The upper shell, the lower shell and the breathing mask set are assembled as a whole. The bottom outer rim of the upper shell is fixedly provided with a sealing strip through screws. The bottom of the lower shell is provided with a bottom cover. The outside of the lower shell is provided with a wearing ring and a wearing band both matched with the sealing strip. The interior of the lower shell is provided with a carbon fiber oxygen tank used for supplying oxygen and a cleaning tank used for absorbing carbon dioxide. A carbon dioxide absorbent is arranged in the cleaning tank. According to the technical scheme of the utility model, the self-rescuer can supply oxygen to a miner, wherein the miner can breathe consciously for 60 minutes with the oxygen provided by the self-rescuer. The carrying weight of the self-rescuer is smaller than 1.1 Kg and the miner only needs 5 seconds to wear the self-rescuer. At present, a miner can breathe for 45 minutes at most with the oxygen provided by a conventional domestic mining self-rescuer and the time-mass ratio thereof is about 0.1.
Description
Technical field
The utility model relates to a kind of self-rescuer, relates in particular to a kind of isolation type compressed oxygen self-rescuer, is used for industries such as fire-fighting respirator, health care, safety of coal mines rescue.
Background technology
As everyone knows, construction operation is a high risk thing under the mine in colliery, careless slightlyly situations such as gas explosion or mine landslide will occur, in case this class event takes place, very likely will become major accident, injure the life security of downhole personnel.Therefore, in the relevant regulations of country for Safety of Coal Mine Production, with regard to the clear and definite oxygen supply self-rescuer that must be equipped with fair amount to the staff under the mine, but oxygen supply self-rescuer of the prior art has the following disadvantages: 1, the carbon-dioxide absorbent of prior art employing mostly is calcium hydroxide, absorptivity is lower, is 32%.There is the shortcoming that the filling dose is many, assimilation effect is poor, miner's expiratory resistance is big.What 2, apparatus of oxygen supply adopted in the prior art is metal gas cylinder (steel cylinder, aluminium alloy seamless gas cylinder), and the time is short, and weight is big, carry inconvenience.Therefore be necessary this is improved.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model provide a kind of safe and reliable, weight is light, the isolation type compressed oxygen self-rescuer that is applicable to the high concentration toxic and harmful, catches fire, escapes under anoxic such as dense smoke and the poison gas environment.
Isolation type compressed oxygen self-rescuer of the present utility model, comprise the last shell and lower casing and the breathing mask group that fit together, the bottom outer rim of last shell fixedly has Sealing strap by screw, there is bottom the bottom of described lower casing, the outside of lower casing be provided with described Sealing strap suitable wear the ring and wear, its innovative point is: described lower casing inside is equipped with for the carbon fiber oxygen cylinder of oxygen supply and is used for the cleaning jar of absorbing carbon dioxide, in the cleaning jar carbon-dioxide absorbent is housed.
Further, the capacity of described carbon fiber oxygen cylinder is 0.25L.
Further, described carbon-dioxide absorbent is lithium hydroxide.
Further, described upward shell and lower casing adopt the plasticity makrolon material to make.
Further, be provided with expiration filter screen and screen pack in the described cleaning jar.
Further, described top of going up shell is provided with observation window and nameplate.
Further, described breathing mask group comprises breathing mask and air bag, and face shield adopts silica gel material to make, and air bag is used for cushioning the immense pressure that the oxygen cylinder exhaust brings, and makes that breathing is more smooth and easy.
By such scheme, isolation type compressed oxygen self-rescuer of the present utility model has the following advantages at least:
1, the utility model adopts the carbon fiber oxygen cylinder, than metal gas cylinder (steel cylinder, aluminium alloy seamless gas cylinder) has better performance, gas cylinder operating pressure 30Mpa, thereby increased gas-storing capacity, the isometric metal gas cylinder of weight ratio alleviates 50%, makes the user more free and relaxed, high-rise building or the degree of depth underground as mine etc. run into use under rescue situation or the major disaster situation more convenient.2, the utility model adopts lithium hydroxide as the absorbent of carbon dioxide, and the temperature that ensures respiration is low, and it is more smooth and easy to guarantee that the miner breathes.Oxygen can be extended to more than the 60min release time.Lithium hydroxide of the present utility model is the tiny crystallization of white monocline.Pungent is arranged.Strong basicity.Energy absorbing carbon dioxide and moisture have the advantage of good absorbing effect, stable performance in air.
Self-rescuer of the present utility model makes the miner that the oxygen of 60min can be provided when escape, carries weight less than 1.1Kg, wears this self-rescuer and only needs for 5 seconds.At present, domestic colliery self-rescuer can only provide the 45min escape required oxygen at most, and temporal quality is than all about 0.1.
