Abstract
An extinguisher mainly solves current problems such as slow speed of extinguishing for extinguisher, poor extinguishing and easily causing casualty. The extinguisher chooses the WuDe alloy as outer shell which is provided with a charging port and a filling port at the upper part and holds CO2, aluminum sulfate and natrii bicarbonas inside. When fire accident occurs, such extinguisher can be thrown into fire field one by one, the extinguisher will explode quickly because of its low melting point of outer shell; chemical reaction occurs upon material inside, foam sticks to flammable material which blocks air and avoid combustion. The extinguisher has the advantages of that: high efficiency of extinguishing; certain distance is between operator of the extinguisher and the fire field, which do not cause any injury.
Description
Technical field
The utility model relates to extinguishing device, particularly a kind of safe and reliable ball-type liquid carbon dioxide fire extinguisher.
Background technology
Plain edition fire extinguisher commonly used at present must be held fire extinguisher and operate fire extinguishing in the scene of a fire when catching fire.Blow-off velocity is slow, weak effect, and easily make the fire extinguishing personnel in the scene of a fire, cause injures and deaths.
Summary of the invention
The purpose of this utility model be to provide a kind of safe and reliable, blow-off velocity is fast, the fire extinguisher of effective, the casualties of avoiding putting out a fire.
The purpose of this utility model is realized by following scheme:
It selects for use martial virtue alloy as shell 1, and it is provided with inflation inlet and filling exit, divides in it liquid CO is housed
22, aluminum sulfate 3, sodium acid carbonate 4.
Three kinds of materials of packing in the above-mentioned shell 1, its liquid CO
2Fill and put in whole cavity, its aluminum sulfate 3 and sodium acid carbonate 4 are irritated respectively and are put in the pipeline of a separation in the enclosure.
Above-mentioned shell 1 is an orbicule.
Advantage of the present utility model is simple in structure, produce easily, simple operation, needing only when catching fire throws away such fire extinguisher in the scene of a fire one by one, its several materials in it after scene of a fire high temperature (about 150～200 ℃) explosion produce chemical reactions, very fast big fire can being knocked out can not be caused fire extinguishing personnel's injures and deaths again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The disclosed structure of above accompanying drawing is the structure of an embodiment of the utility model.Among the figure, 1 shell for the making of martial virtue alloy, its hardness is big, fusing point low (67～69 ℃); 2 is liquid CO
23 is aluminum sulfate; 4 is sodium acid carbonate.
Referring to Fig. 1, Fig. 2, it selects for use martial virtue alloy as shell 1, and it is provided with inflation inlet and filling exit, divides in it liquid CO is housed
2, aluminum sulfate 3, sodium acid carbonate 4; Three kinds of materials of packing in the above-mentioned shell 1, its liquid CO
2Fill and put in whole cavity, its aluminum sulfate 3 and sodium acid carbonate 4 are irritated respectively and are put in the pipeline of a separation in the enclosure; Above-mentioned shell 1 is an orbicule.On the shell 1 inflation inlet similar to bicycle valve core can be set, can charge into gases at high pressure and make CO
2Liquefaction.Simultaneously on the shell of the used pipe ends of can aluminum sulfate and sodium acid carbonate, leave filling exit, martial virtue alloy cap can be added heat-seal with packaging machine after the can.In order to prevent the high temperature accidental explosion, a steel cylinder filled with water can be left in these fire extinguishers in the steel cylinder at ordinary times, close the lid and play cooling effect.When catching fire, these fire extinguishers are thrown away (the fire extinguishing personnel will keep certain safe distance) in the scene of a fire one by one, its shell fusing point is low, meeting very fast fusing in the scene of a fire, interior liquid CO
2Externally pressure increases, and makes its blast, and a small amount of aluminum sulfate that inside pours into and reaction of sodium bicarbonate generate foam, stick on the combustible, and secluding air stops burning, simultaneously a large amount of CO
2Gush out and driven air away, add liquid CO
2Volume increases, and interior can the minimizing sharply descends temperature, thereby the energy quick extinguishing can not damage the fire extinguishing personnel again.
