In the underface of one group of compression nozzle, wind turbine uses axis stream compression fan, the shaft and blade of axis stream compression fan to stretch reeve combustion
Interior is burnt, position is in the top of combustion chamber, and blade is in the top of fuel gas buring rifle, compresses the surface of nozzle；Axis
The hot wind that fuel gas buring rifle generates is accelerated and is blown vertically downward by the rotating vane for flowing compression fan for the first time, and hot wind is passed down through
Accelerated for the second time after compression nozzle, is then directly blowed and sprayed on the aluminium bar being arranged near immediately below each group of compression nozzle.
This technical solution is quickly blowed and sprayed the high-temperature gas that fuel gas buring rifle generates downwards by axis stream compression fan, and hot wind is by
Primary to accelerate, hot wind is again speeded up when passing through several groups compression nozzle downwards, and when hot wind is sprayed from compression nozzle, wind speed carries
At least one times high, the hot wind of high speed is directly blowed and sprayed from compression nozzle to the aluminium bar positioned near exit immediately below it, heat loss
It is few, aluminium bar can fast endothermic, be rapidly heated, to enable aluminium bar to reach scheduled temperature within a short period of time, convenient for subsequent
Extrusion forming is processed.
Further, every group of compression nozzle is disposed to extend along its length, and length and aluminium bar to be heated are long
Spend corresponding, and its cross section inverted trapezoidal with a narrow upper and lower width.The cross section taper of every group of compression nozzle is 40-80 degree.
The several groups compression nozzle is mutually closely to connect side by side.
It is additionally provided on the underface, the position higher than fuel gas buring rifle of respective shaft stream compression fan blade in the combustion chamber
Infrared radiation upper plate, infrared radiation panel is in the low arc surfaced in the high both sides in center.It is equipped with infrared radiation in the bottom of furnace body
Bottom plate.By being set to upper and lower infrared radiation panel, it is ensured that heat radiation energy focus, convergence concentrate on compression nozzle and
Near aluminium bar, heat utilization rate is improved.
Insulating layer is equipped in furnace body, insulating layer is by combustion chamber, the muzzle of aluminium bar, aluminium bar conveying mechanism and fuel gas buring rifle
Portion envelops wherein, there are air duct between combustion chamber in insulating layer, the shape under the turning effort of axis stream compression fan blade
At circulation air path.
Such structure has clear advantage：By quickly blowing and spraying for axis stream compression fan, the acceleration of nozzle is compressed,
Make hot wind high speed high speed after secondary acceleration directly blow and spray to act on aluminium bar, aluminium bar heating speed is fast, and required time is short, carries
High production efficiency.Circulation air path and infrared radiation panel make heat concentrate convergence radiation, scatter and disappear few, can save combustion gas 30-
50%, energy utilization rate is high, substantially reduces production cost.

Specific implementation mode
Referring to Fig. 1, the outermost layer of the infrared gas combustion jet flow aluminum-bar heating furnace of the present embodiment is furnace body 12, fuel gas buring
Rifle 5 is fixed on 12 side of furnace body, and the body of axis stream compression fan 1 is fixed on 12 top of furnace body, and special design is：In furnace body 12
Equipped with independent combustion chamber 4, the blade 1A of axis stream compression fan 1 stretches the top for injecting in combustion chamber 4 and being in combustion chamber 4, combustion
The side for burning room 4 is connected to the muzzle of fuel gas buring rifle 5, and the lower part of combustion chamber 4 is equipped with five groups of compression nozzles 6, aluminium bar conveyer
Structure is in the lower part of compression nozzle 6, and to be heated every aluminium bar 7 corresponds to the underface for being arranged in one group of compression nozzle 6.Combustion gas is fired
It burns the igniting of rifle 5 and generates high-temperature gas, the blade 1A rotations of axis stream compression fan 1 accelerate high-temperature gas for the first time, and blow downwards
It send, generates hot wind, hot wind is accelerated for the second time after passing through compression nozzle 6, then directly blows and sprays near exit immediately below it
On aluminium bar 7, aluminium bar is quickly heated up into predetermined temperature using high speed hot wind.The quantity for compressing nozzle 6 can be according to production requirement, heat
Can size and increase and decrease.
To ensure that hot wind recycles, be equipped with insulating layer 11 in furnace body 12, insulating layer 11 by combustion chamber 4, aluminium bar 7,
Wherein, there are wind between combustion chamber 4 in insulating layer 11 for the muzzle portion envelops of aluminium bar conveying mechanism 8 and fuel gas buring rifle 5
Road forms circulation air path 2 under the turning effort of 1 A of axis stream compression fan blade, when the blade 1A rotations of axis stream compression fan 1
When, the hot wind that fuel gas buring rifle 5 generates is blowed downwards, is directly blowed and sprayed on aluminium bar 7 after overcompression nozzle 6, and aluminium bar is heated
7, the waste heat wind after heating rises periphery between combustion chamber 4 and insulating layer 11（As shown by the arrows in Figure 1）, and along circulation air path
