Abstract
The utility model relates to a pulsed super-fine-powder fire extinguishing equipment, pertaining to cold aerosol fire extinguishing equipment, and is characterized with a body case, super-fine-powder fire extinguishing agents (cold aerosol fire extinguishing agents) and a starter. The body case comprises a crust and aluminium coating used for the seal of a spout; the starter consists of thermal line, of which the fire point is equal or greater than 135 degrees; the conduction velocity is more than 0.5 meters per second; start elements comprising sleeves sleeved with the thermal line; an aluminium plate arranged tightly on the interior of the crust with a nut and a perforated bolt which impenetrates the thermal line; the gas generating components comprising gas generating product connected with the thermal line and celluloid film which is positioned on the aluminium plate to seal the gas generating product. The shape of the crust can be bowl, cylinder, half ball, double sphere, taper, calabash or whichever above. The utility model has the advantages of safety, reliability, efficiency, automatism, innocuity, efficient fire extinguishment, intensive-directed pulse jet and great impact force, thereby meeting the requirement of fire attack in disastrous fire.
Description
The ultra-fine powder automatic fire extinguisher down of technical field pulse belongs to cold air sol self-extinguishing equipment field.
The present ultrasonic aerosol fire-extinguishing equipment of background technology is mechanically activated, and conventional air for continuous is sprayed, and it comprises housing, gas bomb, powder extinguishing agent.During fire extinguishing, extinguishing chemical is to spray dry-chemical fire extinguishing continuously under the pressure effect of Compressed Gas in the gas storage steel cylinder.Its shortcoming is: fire extinguisher itself is exactly a pressure vessel, the casualty accident of blasting easily; Gas leakage need be made regular check on easily, the maintenance trouble; Attack time is long, and efficient is low.
The summary of the invention the purpose of this utility model provides a kind of automatic fire extinguisher of puluse ultrafine dry powder efficiently quick, simple in structure, safe and easy to use
Of the present utility model being characterised in that: it contains: housing, and it comprises: shell, cased granularity ultra-fine dry powder extinguishing agent and the aluminium film used of housing spout seal below 30 μ m; Conduction of velocity is greater than the starter of 0.5 meter per second, it comprises: by burning-point more than or equal to 135 ℃ and to flame or temperature sensitive heat-sensitive line be enclosed within the start assembly that the outer sleeve pipe of heat-sensitive line is formed, by being pressed on aluminium sheet, the gas generating agent that contacts with heat-sensitive line of housing inboard by nut with the perforated bolt that is running through heat-sensitive line and withholding on aluminium sheet in order to the common aerogenesis assembly of forming of the nonmetal film that encases gas generating agent.
Described housing is any in bowl-type, cylindrical shape, hemispherical, two sphere, taper or the Pear-Shaped; The granularity of described ultra-fine dry powder extinguishing agent is below 20 μ m; Described gas generating agent granularity is less than or equal to 83 μ m; Described start assembly conduction of velocity is greater than 0.5 meter per second, and safe preparation process.
Use proof: it has reached intended purposes.
Description of drawings:
Fig. 1 cylindrical shape fire extinguisher
Fig. 2 bowl-type fire extinguisher
Fig. 3 starter
The specific embodiment is asked for an interview Fig. 2 and Fig. 3.The 1st, aluminium shell; The 3rd, steel ring; The 4th, be fixed on the aluminium film on the shell 1, they form housing jointly; The 2nd, granularity is the following ammonium phosphate ultra-fine dry powders of 20 μ m; The 7th, withhold aluminium sheet jointly with nut 12 and perforated bolt 8 in shell 1 inboard; The 6th, gas generating agent is that 83 μ m sodium nitrate and magnesium powder are formed with granularity, the 5th, be used to encase gas generating agent 6 and the celluloid film withheld by aluminium sheet 7, and they have formed the aerogenesis assembly jointly; The 9th, pass perforated bolt 8 and insert start assembly in the gas generating agent 6, the cotton thread 10 that start assembly 9 steep by potassium chlorate and sucrose be enclosed within cotton thread 10 glass fiber sleeve pipes 11 outward and form, the burning-point of cotton thread 10 is 135 ℃, conduction of velocity is 0.5 meter per second; Above-mentioned aerogenesis assembly and the start assembly 9 common starters of forming.In Fig. 1, the 13rd, the cylinder type shell, remaining is identical with Fig. 2, Fig. 3.
The utility model is not to spray the ultra-fine dry powder extinguishing agent fire extinguishing by the gas pressure in the high-pressure gas cylinder, but the pyrotechnic compound that adopts safety, reliable, nontoxic pollution-free is as gas generating agent.During use it is placed the top or the side of object of protection; when the fire the condition of a disaster; directly experience flame; the chemistry start assembly is lighted and is transmitted rapidly; make the gas generating agent in the starter that chemical reaction take place immediately, produce a large amount of gases, the aluminium film 3 on the shell 1 is broken; the impulse jet ultra-fine dry powder extinguishing agent is stamped out the flames.
This device has the following advantages:
1, safe and reliable. Its power source adopts pyrotechnic compound, does not contain explosive and the noxious materials such as explosive, protects Be perfectly safe when having demonstrate,proved production, use and having transported.
2, adopt chemical Starting mode, in the unmanned situation, its direct feeling flame and temperature, spontaneous Passive startup does not need fire detecting and alarm equipment and power supply, avoids misoperation.
3, do not need pipe network and high pressure tank, do not exist withstand voltage and the gas leakage problem, construction costs is low, Be convenient to safeguard.
4, realize the pulse high-effect fire-extinguishing, concentrate guide type to spray, impulsive force is strong, and the protection area is big, satisfies heavy, especially big space fire attack needs.
5, nontoxic nothing corrosion does not destroy atmospheric ozone layer, compliance with environmental protection requirements.
