Abstract
The utility model relates to an automatic fire extinguisher using smoke and dry powder together, which is characterized in that a smoke fire extinguishing agent with a geometric shape and fire transmission tablets are orderly arranged in a smoke generator through a medicine charging frame; the smoke generator is fixed by a clamping frame which is provided with an electric igniter; in addition, a sieve which is provided with a dry powder fire extinguishing agent is arranged at a position at a certain distance with the electric igniter. The utility model has the advantages of simple structure and easy installation. When the automatic fire extinguisher using smoke and dry powder together meets wrong motion or misoperation, the utility model has strong self-safety. The range of the smoke spraying is large, the lasting time is long, and the pressure is stabile, so the fire extinguishing effect is fast as well as good.
Description
The utility model relates to a kind of smog-dry powder coupling automatic fire extinguisher, particularly a kind of automatic fire extinguisher that is used for the storage tank of oil and chemical products.
The known automatic fire extinguisher that is used for the storage tank of oil and chemical products, extinguishing device such as Chinese patent CN852032242 proposition, its architectural feature is that what to be adorned in the smoke generator is pulverous smoke extinguishing agent, since it place sieve aperture guide shell that fuse cord is housed around, though when meeting the fire generation, this device can start rapidly, can reach the purpose of fire extinguishing.But still also have deficiency, and first complex structure, processing is installed all inconvenient; Its two be since in the smoke generator smoke extinguishing agent of packing into be pulverous, so the after-combustion of igniting is irregular, and the pressure variation is greatly, aerosol spraying time instability, the easy moisture absorption of itself in addition, and influence flammability; It three is that fuse ignition is not good enough; It four is to lead burning device to account for very large space in smoke generator, and influences the filling weight of smoke extinguishing agent.
The purpose of this utility model is to overcome the deficiency of known technology, and provides a kind of simple in structure and the inherently safe performance is good, the automatic fire extinguisher that improves greatly of fire extinguishing reliability.
The purpose of this utility model is achieved in that the bottom of smoke generator is equipped with the smoke extinguishing agent with geometry by the powder charge frame, uppermost surface at smoke agent is equipped with starting mix, can be stuck on the smoke extinguishing agent again fixing starting mix and leave on the card frame of distance electric igniter is housed with starting mix, with electric igniter leave distance above screen cloth is housed, refilled powder extinguishing agent on the screen cloth.
Positive and negative the two poles of the earth that electric igniter in the utility model is drawn pass outlet.
The advantage that the utlity model has shows: 1. removed the sieve aperture guide shell that fuse cord is housed in the smoke generator, made structure become simple and easy to process, alleviated the weight of labour intensity and device simultaneously.2. because the structure that has adopted smoke extinguishing agent with certain geometrical shape and powder extinguishing agent in the smoke generator and ignited with starting mix, the institute so that smoke extinguishing agent can clocklike burn, make it to produce enough fire extinguishing smog gas flow and steady pressure, increased the big range aerosol spraying time, improved self-security, reliable extinguishing property improves greatly thereupon.
The utility model has following accompanying drawing:
Fig. 1 is used for the structural representation of storage tank for the utility model;
Fig. 2 is the structure partial generalized section of smoke generator among Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
The storage tank 1 outer smoke generator 5 that is equipped with that is used for oil or chemical products, the smoke extinguishing agent 10 with geometry is equipped with in bottom in smoke generator by powder charge frame 11, smoke extinguishing agent can be processed into round pie or polygon geometry, after-combustion is regular in order that ignite, and present embodiment is selected the smoke extinguishing agent of round pie.Uppermost surface at smoke extinguishing agent is equipped with starting mix 9, for fixing starting mix with can be stuck in and refilled card frame 12 on the smoke extinguishing agent, in addition for can better light starting mix, then need between starting mix and card frame, to leave distance, and on the card frame, the electric igniter 8 that has positive and negative the two poles of the earth is housed also, its the two poles of the earth lead to outlet 13, with the electric igniter place of keeping at a certain distance away screen cloth 7 are housed, and powder extinguishing agent 6 is housed on the screen cloth.See shown in Figure 2.
When storage tank meets the fire generation, after reaching uniform temperature, temperature-sensing probe 3 is connected power supply, the two poles of the earth of the electric igniter of drawing by the outlet on the smoke generator, electric igniter is detonated, light the starting mix smoke extinguishing agent that ignites and produce a large amount of smog gases and carry powder extinguishing agent and enter in the storage tank through conduit 4,, reach effective fire extinguishing effect by shower nozzle 2 knock down the flames.See shown in Figure 1.
Claims (2)
1, a kind of smog-dry powder coupling automatic fire extinguisher, form by smoke generator, conduit, shower nozzle, it is characterized in that: the smoke extinguishing agent 10 with geometry is equipped with in the bottom of smoke generator 5 by powder charge frame 11, uppermost surface at smoke extinguishing agent is equipped with starting mix 9, can be stuck on the smoke extinguishing agent again fixing starting mix and leave on the card frame 12 of distance electric igniter 8 is housed with starting mix, with electric igniter leave distance above screen cloth 7 is housed, refilled powder extinguishing agent 6 on the screen cloth.
2, automatic fire extinguisher according to claim 1 is characterized in that: the positive and negative the two poles of the earth of drawing on the electric igniter pass outlet 13.
