Description
Technical field
The utility model is related to a kind of wheeled mixed powder fire extinguishers for refueling station.
Background technology
With promoting the use of for clean energy resource, the function of domestic original filling station, be extended to oiling, aerating with
Electric vehicle fills electrically compatible multiple-energy-source multi-purpose station.Especially include that filling is easy since energy kind and aggregate reserve increase
Fire explosive liquefied petroleum gas, natural gas, liquefied natural gas so that the extinguishing ability of existing fire extinguisher is filled with oiling aerating
Requirement of the electric multi-purpose station to fire-fighting supportability is incompatible.
The mobile model fire extinguisher configured in refueling station, predominantly ABC dry powder extinguishers, in ABC dry powder extinguisher tanks
Fill ammonium phosphate powder extinguishing agent.《Dry powder fire extinguishing agent》In standard GB/T 4066.2-2004, make to playing core fire extinguishing
The not quantitative requirement of the content of ammonium dihydrogen phosphate." survey report " of the dry powder fire extinguishing agent for each producer production announced
It showing, in the ABC powder extinguishing agent of most domestic producer production, the determining ammonium biphosphate content for playing core fire extinguishing is relatively low,
It is 50%, the auxiliary materials such as remaining ammonium sulfate for being 25~30%, and mica powder, diatomite, silicone oil without fire extinguishing effect.These
Auxiliary material occupies significant proportion, reduces the fire extinguishing effectiveness of dry powder fire extinguishing agent.
In recent years, documents and materials both domestic and external and test report are pointed out, fire extinguishing is played in ammonium phosphate powder extinguishing agent
The diameter of the critical particle of effect is at 30 μm or less.《Dry powder fire extinguishing agent》, it is specified that ammonium phosphate dry-powder in national current standard
The particle content of extinguishing chemical Zhong≤40 μm is not less than 50%.That is, about 50% or so dry powder fire extinguishing agent particle does not have
Have and generates fire extinguishing effect.
The a large amount of cases for putting out gasoline fire show the fire that leaking gasoline occurs, and the initial stage after fire generation is only
The of short duration time for having several tens of seconds, it is extended to fuel oil big fire rapidly thereafter.Portable dry powder fire extinguisher capacity is small, injecting time
It is short, it is difficult to put out the gasoline big fire in extension and affect best attack time adversely.Under same case, aircraft stand in U.S. army airport
Hand fire extinguisher has been thrown aside, the wheel fire extinguisher of large capacity is changed to, and has increased the configuration total amount of wheel fire extinguisher, with profit
In quickly putting out fuel fire.
The beginning of this century, China successfully develop ultra-fine dry powder extinguishing agent.It is mainly characterized by particles ultra fine,《It is ultra-fine dry
Powder extinguishing chemical》Mark pushes away 90% Jing≤20 μm Li of regulation.The large specific surface area of ultra-fine dry powder extinguishing agent, dispersivity is good after injection, ultra-fine
Particle enters fast decoupled in flame, cuts off combustion reaction chain, generates high fire extinguishing effectiveness, is ABC powder extinguishing agent fire extinguishing
The highest extinguishing chemical of fire extinguishing effectiveness in 6~10 times of efficiency and known extinguishing chemical.
Invention content
To solve the above technical deficiency, the utility model provides a kind of wheeled dry powder for refueling station and goes out
Firearm, the ability for refueling station will be significantly improved putting out fuel oil, electrical fire.
The utility model is realized by following measures：
The utility model is a kind of wheeled mixed powder fire extinguisher for refueling station, including vehicle frame, the vehicle frame
Bottom is provided with wheel, and metal can is vertically arranged on vehicle frame, and compressed nitrogen is stored in the metal can and mixing is dry
Powder extinguishing chemical, metal can top are provided with extinguisher valve, and described extinguisher valve one end is connected with extends into metal vertically
Flour extraction pipe in tank body, the extinguisher valve other end are connected with defeated powder hose, and the defeated powder hose end is provided with belt switch valve
The spray gun of door.
Above-mentioned vehicle frame includes cuboid framework, and the metal can is fixed in cuboid framework, the cuboid framework
Bottom rear is provided with the wheel of pneumatic tire, and bottom is provided with the support leg being bent straight down on front side of cuboid framework.
Above-mentioned mixed powder extinguishing chemical is ultra-fine dry powder extinguishing agent and ABC powder extinguishing agent.
It is provided with the supporting rack extended forward on front side of above-mentioned vehicle frame, the defeated powder soft tube winding is on supporting rack.
It is provided with pressure gauge at the top of above-mentioned metal can.
Above-mentioned vehicle frame backside top is provided with the handle tiltedly to extend back.
The utility model has the beneficial effects that：Mixed powder extinguishing chemical has taken into account ABC powder extinguishing agent and ultra-fine dry powder goes out
Respectively advantage ,≤30 μm great amplitude Ti Gao or less particle proportion make the fire extinguishing effectiveness of wheel fire extinguisher be pushed away than original for fiery agent
Vehicle type dry powder extinguisher improves 2~3 times.Pneumatic tire is installed under vehicle frame, when pushing wheel fire extinguisher, when vehicle frame inclines Dou
30 °, the center of gravity of metal can is located on the vertical line of two pneumatic tire lines, and mobile light and fast can fast move fire extinguisher
To scene of fire, quick-reaction capability is improved.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1 vehicle frame, 2 metal cans, 3 pressure gauges, 4 extinguisher valves, 5 flour extraction pipes, 6 mixed powder extinguishing chemicals, 7 vehicles
