Abstract
A dry powder fire extinguishing device with a chamber capable of being gasified comprises a direct current power supply (1), a control switch (2), a starting head (3), a starting agent (4), driving drug (5), the chamber (6) and a fire extinguishing device casing (7). A dry powder fire extinguishing agent (8) is filled in the casing (7), two leads of the starting head (3) are connected with the direct current power supply (1) and the control switch (2) respectively, and the control switch (2) is connected with the other pole of the direct current power supply (1). The chamber (6) can be gasified when the driving drug burns and comprises a drug pipe (61), an upper cover (62) and a lower cover (63). The drug pipe, the upper cover and the lower cover are all made of propellant powder or propellant or celluloid or polyethylene plastics easy to be gasified, and the wall thickness of the propellant powder or the propellant or the celluloid or the polyethylene plastics is smaller than 0.5 mm. The driving drug (5) is made of powder drug with grain size smaller than 0.05 mm. In addition, a little starting agent (4) should be added around the starting head (3) so as to increase starting energy and light the driving drug (5) fast, simultaneously and totally. A steel chamber is replaced with the chamber capable of being gasified so that the dry powder fire extinguishing device is environment-friendly, convenient to produce, lower in price and safe to use.
Description
Technical field
The utility model relates to a kind of extinguishing device, relates to a kind of coyote hole that drives medicament that loads and when fire extinguishing, also can become gas and drive the combustion type dry powder extinguishing installation that spills dry powder.
Background technology
From China's patent of invention in 1987 number be behind 87106704.8 the automatic air-jet type hand powder fire extinguisher, to produce multiple combustion type dry powder extinguishing installation both at home and abroad, this type extinguishing device can self-extinguishing, and what have obtains good economic benefit and social benefit.But yet there is certain defective.General dry powder extinguisher is to spray dry-chemical fire extinguishing with high pressure nitrogen or carbon dioxide gas, and the combustion type dry powder extinguishing installation is that the gases at high pressure that utilize burnings such as gunpowder or propellant, pyrotechnic compound to generate drive to spill to do to divide and put out a fire.Gunpowder is will be under HTHP could smooth combustion complete.If coyote hole is broken, abrupt pressure reduction, gunpowder will be ended burning, so must be with the very high steel coyote hole of intensity.With the steel coyote hole very big defective is arranged.The one, the steel of a large amount of high energy consumption high pollutions of needs, the 2nd, processing difficulties costs an arm and a leg, and the coyote hole of a tool 4kg extinguishing device needs the many steel of 1kg, 24 yuan of costs.If particularly crudy contingency is bad, the danger of breaking is arranged during fire extinguishing.Therefore factory and user hope without the steel coyote hole.
The utility model content
The utility model is that the patent No. is the follow-up invention of 200520114435.5 utility models " controlling dry powder extinguisher " more.The shell structure of many control techniques and extinguishing device that promptly keeps this utility model is constant.The purpose of the utility model is to overcome the defective of known product, provides a kind of coyote hole to gasify, and environmental protection more is economic and practical, processes more conveniently, uses dry powder extinguishing installation safer, that can control more.
The dry powder extinguishing installation that the utility model coyote hole can gasify comprises power supply, gauge tap, startup head, starts agent, drives medicament, coyote hole, extinguishing device housing and is seated in the powder extinguishing agent in the housing; Starting head is contained in the driving medicament in the coyote hole; After two leads that start head pass from pencil loam cake and housing port; Connect with gauge tap, power supply respectively, another utmost point of power supply connects with lead with the other end of gauge tap.
The dry powder extinguishing installation that the utility model coyote hole can gasify; Wherein said coyote hole comprises pencil, loam cake, lower cover; All be to make with the nonmetallic materials that at high temperature can gasify, and wall thickness is less than 0.5mm, said nonmetallic materials are vinyon or propellant powder or propellant; Driving medicament powder application powder medicament wherein, and the powder diameter should be less than 0.05mm.Should add the startup agent around the startup head wherein, start energy so that increase, can light the driving medicament fast comprehensively, the driving medicament has all been burnt when coyote hole breaks as far as possible, even have a surplus medicine, surplus medicine also all is heated to ignition point.Can not produce the surplus medicine of ending burning.
Description of drawings
The main pseudosection of the structural representation of the dry powder extinguishing installation that accompanying drawing can gasify for the utility model coyote hole
The specific embodiment
The dry powder extinguishing installation that can gasify with reference to the coyote hole of accompanying drawing the utility model; Comprise dc source (1), gauge tap (2), startup head (3), start agent (4), drive the powder extinguishing agent (8) that loads in medicament (5), coyote hole (6), extinguishing device housing (7) and the housing (7); Powder extinguishing agent (8) can be common dry powder, also can be ultra-fine dry powder or other powder extinguishing agents.Two leads that start head (3) are electrically connected with dc source (1), gauge tap (2) respectively, and gauge tap (2) is electrically connected with another utmost point of dc source.
The coyote hole (6) of the dry powder extinguishing installation that the utility model coyote hole can gasify comprises pencil (61), loam cake (62), lower cover (63), all is to make with the nonmetallic materials that high temperature is prone to down gasify.Nonmetallic materials are that vinyon or celluloid or propellant powder or propellant and thickness are less than 0.5mm.The driving medicament (5) of filling is used the Powdered medicament of particle diameter less than 0.05mm in the coyote hole (6) simultaneously, and medicament is done the driving medicament with single original washing powder, double-basis powder or other mealy medicines.Also require to attach a certain amount of startup agent (4) on every side so that increase the startup energy, carminative (5) can be lighted fast comprehensively at startup head (3).
The operation principle of the dry powder extinguishing installation that the coyote hole of the utility model can gasify is that 200520114435.5 utility model operation principles are identical with the patent No.; When gauge tap (2) by controlled open after; Electric current is switched to startup (3), starts (3) initiation startup agent (4), and startup agent (4) causes driving medicament (5), coyote hole (6) also begins to gasify.Combustion gas becomes sphere evenly to expand at a high speed, orders about dry powder and also becomes sphere evenly to spray at a high speed.The coyote hole gasification increases gas quantity, has improved the fire extinguishing effect.Increase along with radius this moment, cube increasing of pressure and radius and reducing, so fire extinguishing radius (volume) is greatly, and the radius of damage is little; On the contrary, the combustion gas of steel coyote hole is few, and combustion gas becomes the wire harness shape to penetrate; Wire harness pressure increases with radius and reduces slowly, so the radius of damage is big, space part dry powder density is little between the wire harness; So fire-fighting area is little, so the coyote hole of the utility model dry powder extinguishing installation that can gasify, not only overcome the defective of known product; The advantage that keeps known product, and test also prove safer, the fire extinguishing better effects if.
