The injection apparatus 700 at end.The invention of the powder fire fighting truck is characterized by, the powder feeding mechanism 500, including at least two powders
Supply unit.
Under this structure, two powder supply units can both store the powder of identical type, with single in a powder supply
It gives and supplements when member supply is insufficient, reach efficient fire extinguishing for a long time；Also different types of material can be stored, as one stores
Physical fire extinguishing powder, the powder secondly storage of chemical type is put out a fire, which kind of fire extinguishing powder or choosing selected according to scene of fire situation
Select two kinds of fire extinguishing powders joint fire extinguishings, that it changes a kind of conventionally employed fire-fighting principle that powder is individually put out a fire, using physics and
Chemical double action joint fire extinguishing, not only covering isolation air reached extinguishing effect, but also chemically inhibiting effect from physical characteristic
On reach extinguishing effect, further increase fire-fighting efficiency and the scope of application.
Preferably, drive air source 400, it is optional but be not limited only to as the non-combustion-supporting gas tank of high pressure, as nitrogen, carbon dioxide or
The combination etc. of the gas tanks such as inert gas or wind turbine, engine as shown in Figure 4 and air compressor machine.
More preferably, powder supply unit, it is optional but be not limited only to for powder material tank or powder interface any one or
It is a variety of, it can both be equipped with the powder material tank carried by itself, fire extinguishing powder is promptly provided, and also can connect external powder by powder interface
Material source, such as other fire fighting trucks, bulk cement carrier supplement provide fire extinguishing powder.
More preferably, the powder stored in the powder supply unit, it is optional but be not limited only to include cement, flyash,
Sandstone, miberal powder etc. have the heavy fine-grained powder of constant weight, are acted on by physics covering, are reached in a manner of air-isolation
To extinguishing effect, referred to as physical fire extinguishing powder；Or the dry powder such as ammonium phosphate salt, hydroxide (sodium hydroxide, potassium hydroxide),
It reaches extinguishing effect, referred to as chemical type fire extinguishing powder by the effect of Chemical Inhibition, or is matched by certain for the two
Mixture, extinguishing effect is reached by physical chemistry synergy.
Exemplary, by taking Fig. 4 as an example, the powder feeding mechanism 500 of the powder fire fighting truck includes two powder supply units,
One is the powder material tank 511 being set on chassis, secondly for the powder interface 512 for external powder source.Specifically, driving air source
400 outlet end is connected to powder material tank 511, powder interface 522 respectively by the first pipeline, the second pipeline.In practical operation,
Fire fighter, can in powder material tank 511 and powder interface 512 the identical material of storage, i.e., physically or chemically type fire extinguishing powder or
Its mixture, in the self-contained powder material tank 511 of fire fighting truck powder will use totally when, it is external other with powder interface 512
The powder sources such as fire fighting truck or bulk cement carrier supplement powder, to reach efficient lasting fire extinguishing for a long time；Or in powder material tank 511
The material different with storage in powder interface 512, i.e., one storage physical fire extinguishing powder, another storage of chemical type fire fighting powder
Material, with the type for the material that according to live fire condition, such as catches fire, next selective is gone out using physical fire extinguishing powder or chemical type
The proportioning of fiery powder or the two according to a certain percentage is independently gone out with changing original single fire-fighting mode using new physical chemistry
Fire or physical chemistry joint fire extinguishing, to further increase fire-fighting efficiency and the scope of application.
More preferably, as shown in figure 3, being additionally provided with switch valve 800 on above-mentioned first pipeline or/and the second pipeline, disappear
Anti- personnel are when in face of different fire types, you can by the switch valve 800 select powder feeding mechanism 500 some or it is multiple
Powder supply unit is put out a fire.It is exemplary, as shown in figure 4, by taking the first-second switch valve 810,820 as an example, switch can be passed through
Above-mentioned switch valve, to select only to use powder material tank 511 or powder interface 512 is only used to supply powder, or selection powder material tank 511 and powder
512 joint supply powder of interface.More preferably, the switch valve 800, it is optional but be not limited only to as flow control valve, with basis
Scene of fire situation selects the uninterrupted and powders mixture proportioning of powder supply, further increases fire-fighting efficiency.
