Description
Technical field
The present invention relates to a kind of fire extinguishers, and in particular to a kind of automatic dry chemical fire extinguisher with alarm function.
Background technique
Existing automatic fire extinguisher commonly relies on the isostructural essence of smoke temperature sensor, control circuit, fire main
Extinction by automatic sprinkling is realized in close fit.But the system structure is complicated, easily damaged and cost is high, and also certain probability is not being sent out
Starting when calamity of lighting a fire.Therefore, the automatic fire extinguisher that a kind of high reliablity, structure are simple, mistake is avoided to start is needed.
Summary of the invention
In view of this, the present invention provides a kind of high reliablity, the simple automatic fire extinguisher of structure.
The purpose of the present invention is realized by the following technologies: a kind of automatic dry chemical fire extinguisher with alarm function, feature
It is: including columnar, hollow metal shell, is provided with jet port at the top of the metal shell；The bottom of the metal shell
Portion expands filled with expansion oxidant layer and is filled with ABC fire-fighting powder layer between oxidant layer and jet port；The expansion oxidant layer and ABC put out a fire
Tabula has an Emulsoid-film between dry powder layer；It sticks together in metal shell inner wall at the edge of Emulsoid-film；It is covered outside the jet port
There is metal foil；It further include alert component, the alert component includes the power supply connected by conducting wire first place, induction room and alarm
Device；The induction room is sealing, hollow glass cartridge, is filled with thiosulfuric acid sodium crystal in glass cartridge；Glass cartridge
It is mounted on metal shell lateral surface；The positive pole is connect by conducting wire with the intracorporal thiosulfuric acid sodium crystal of glass case；Institute
Stating conducting wire, it penetrates the glass cartridge with one end of induction room connection and contacts with sodium thiosulfate.
The expansion oxidant layer can be made of the raw material for the generation expanding gas that is heated in the prior art.It is swollen after fire occurs
Swollen oxidant layer generates a large amount of expanding gas, and latex film is made to be expanded to explosion, finally by the powder spray injection of ABC fire-fighting powder layer and
Flame is covered, realizes fire extinguishing.Alarm assemblies, the intracorporal sodium thiosulfate of can is especially arranged in the present invention on the outside of metal shell
Crystal is melted at 48 DEG C, obtains electric conductivity and alarm device and power supply is connected, alarm device sounds an alarm, and on the one hand can notify to use
Fire is noticed at family, on the other hand also can avoid fire extinguisher because mistake occurs close to heat source (such as heating, gas-cooker) of safety
Starting.The alarm device can be selected the prior art realize, as buzzer alarm, light alarm device, be mounted with 4g communication module
Transmitting device etc..
Further, the thickness of Emulsoid-film increases along center to edge.
Emulsoid-film can completely cut off air, avoid expansion oxidant layer denaturation failure.Center thickness is relatively thin to be conducive to it as quick-fried
Fried site.
Further, the metal shell inner wall of the Emulsoid-film lower zone stretches out multiple metal conducting strips.
Metal conducting strip can be made with metal shell of integral forming process, the modes such as can also be welded and be assembled.Gold
Metal shell can be increased and expand the contact area of oxidant layer by belonging to thermally conductive sheet, expanded oxidant layer with quick heating, promoted releasing for gas
It puts.
The expansion oxidant layer is made of sodium bicarbonate powder.
Sodium bicarbonate carbon dioxide gas at high temperature, is conducive to further block combustion reaction.
The expansion oxidant layer further includes active carbon powder, cupric sulfate pentahydrate powder, citric acid powder, active carbon powder, carbon
Sour hydrogen sodium powder end, cupric sulfate pentahydrate powder, citric acid powder mass ratio be 1:7:6:7.
The present invention has been especially added with cupric sulfate pentahydrate powder, at 150 DEG C can decompose a large amount of water, cause citric acid and
The reaction of sodium bicarbonate, the rapid reaction, acutely, a large amount of carbon dioxide gas can be released in a short time, satisfaction is gone out
The demand of fire.And active carbon particle can increase the air permeability of powder, further increase efficiency when carbon dioxide is precipitated, and avoid
Agglomeration, blocking.
The expansion oxidant layer further includes stabilizer, and the stabilizer includes 5-15 by mass parts of nanometer gold bar, 25-50 parts
Nano-titanium dioxide；The stabilizer and the mass ratio of sodium bicarbonate powder are 1:(100-300).
The present invention is also especially added with nano-titanium dioxide and nanometer gold bar as stabilizer, in the presence of the two, sodium bicarbonate
The temperature value of decomposition will rise, and decomposition is hardly happened at 90 DEG C or less, can effectively extend the validity period of product of the present invention, really
Protect sodium bicarbonate with citric acid reactions.
