A kind of survival capsule is with mixing cold-storage device
Technical field
The utility model relates to the mine lifesaving appliance, and especially a kind of survival capsule is with mixing cold-storage device.
Background technology
Mining survival capsule is the key equipment of the great calamity emergency rescue in mine, for 700 meters dark following mines, ground temperature is many more than 35 ℃, when particularly mine disaster occurring, atmosphere draught-free in the tunnel, even temperature is up to 40 degree, mining survival capsule takes cold-storage device to realize cool-down dehumidification, cold-storage device generally adopts the ice cold-storage, or the carbon dioxide cold-storage, but do not find as yet these two kinds of cold-storage modes are used in combination.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of survival capsule cold accumulating device by ice is provided, and the mode that it adopts the ice cold-storage to combine with the carbon dioxide cold-storage and use can provide cold and power simultaneously.
The purpose of this utility model realizes as follows: a kind of survival capsule is provided with by CO with mixing cold-storage device
2The CO that gas cylinder, bus-bar, swell refrigeration blower fan, heat interchanger are formed
2Cold-storage device, it is characterized in that: also be provided with cold accumulating device by ice, this cold accumulating device by ice is provided with explosion-proof casing outward, and inside is provided with Ice Storage Tank, air channel and refrigeration unit, and the Ice Storage Tank bottom is provided with the air channel, the two ends, air channel form air intake and air outlet, establish Ice storage coiled pipe in the Ice Storage Tank, be communicated with refrigeration unit, heat exchanger is communicated with refrigeration unit, the air outlet of swell refrigeration blower fan is connected with the air intake in air channel, and heat interchanger is arranged on the air outlet place in air channel.
In addition, the air intake of swell refrigeration blower fan is connected with air purification medicine groove.
Refrigeration unit places in the casing.
Heat exchanger places above the explosion-proof casing.
Effect of the present utility model is: when blast or fire occurring, but both cold-storages is put out a fire by the carbon dioxide of discharge, but self provide power to make air cleaning unit work again, the temperature environment that is fit to people living is provided, prolongs battery application life, reduced running cost.

The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model comprises cold accumulating device by ice and CO
2Cold-storage device two parts are formed.Cold accumulating device by ice is provided with explosion-proof casing outward, inside is provided with Ice Storage Tank 12, air channel 13 and refrigeration unit 15, Ice Storage Tank 12 bottoms are provided with air channel 13,13 two ends, air channel form air intake 9 and air outlet 10, establish Ice storage coiled pipe 14 in the Ice Storage Tank 12, are communicated with refrigeration unit 15, refrigeration unit 15 places in the casing 17, heat exchanger 16 places above the explosion-proof casing 19 for the fin coiled, by natural air cooled, is communicated with refrigeration unit 15.Air channel 13 is by the flat board 20 of upper and lower two-layer horizontal positioned, dividing plate 22 and vertically pass dull and stereotyped 20 siphunculus 21 that are provided with and constitute, and dividing plate 22 is located between upper and lower two-layer dull and stereotyped 20, passes through in order to air, and siphunculus 21 is used for cooling water to be passed through.Filled with polyurethane foam foam between Ice Storage Tank 12 and the explosion-proof casing 19, its gap back cushion piece 18 guarantees.CO
2Cold-storage device is by the liquid CO of hydrocone type
2Gas cylinder 1, bus-bar 2, swell refrigeration blower fan 5, heat interchanger 8 are formed, and couple together with high-voltage tube each other, and pressure piping is provided with stop valve 3, control valve 6 and does not have spring one way valve 4.The air intake of swell refrigeration blower fan 5 is connected with air purification medicine groove 7, and the air outlet of swell refrigeration blower fan 5 is connected with the air intake 9 in the air channel of cold accumulating device by ice 13, and air outlet 10 places in the air channel 13 of cold accumulating device by ice are provided with heat interchanger 8.
During work, the liquid CO of hydrocone type
2High-pressure liquid CO in the gas cylinder 1
2, through bus-bar 2, stop valve 3, control valve 6, enter swell refrigeration blower fan 5, after the expansion, the rotation of the impeller of swell refrigeration blower fan 5, liquid CO simultaneously
2Become the less gaseous state CO of low-temperature pressure after the expansion
2, entering copper pipe heat interchanger 8, no spring one way valve 4 is discharged outside the survival capsule 11.Under the effect of swell refrigeration blower fan 5, through air purification medicine groove 7, suck air in the survival capsule 11, by swell refrigeration blower fan 5, send into the air intake 9 in the air channel 13 of cold accumulating device by ice, after the cold accumulating device by ice cooling, 13 air outlet 10 is sent from the air channel in air channel 13, blow over copper pipe heat interchanger 8, enter in the survival capsule 11 after the cooling once more.
