Description
Technical field
The utility model belongs to ladle baking technical field of heating, and in particular to a kind of premix I. C. jetting formula mixed gas
Ladle baking facility.
Background technology
First generation bushing type roaster without preheating device at present, efficiency of combustion are low etc.；Second generation heat-storage ladle roaster structure
Complexity, four-way reversing valve service life are low, heat storage is easy to block, troublesome maintenance etc.；Third generation high combustion rate burner roaster noise
Greatly, when the medium of burning is the mixed gas of middle high heating value, coke-stove gas, the service life of backpack cover is not grown, and burner replaces fiber crops
Tired, the degree of automation is not high, without accurate temp measuring system etc., meanwhile, a kind of rational method of comparison is found, steel mill's thermal energy is improved
Equipment efficiency of combustion reduces steel mill's carbon emission, reduces environmental pollution, especially brings environment dirt to mitigating puzzlement China's haze always
The influence of dye play the role of one it is vital.A kind of premix I. C. jetting formula mixed gas is proposed based on above factor spy
Ladle baking facility.
Invention content
Used technical solution is to provide a kind of premix I. C. jetting formula to the utility model to solve above-mentioned technical problem
Mixed gas ladle baking facility, including backpack cover, dismounting boss, pre- hot-flow flue and burner；Boss is dismantled to be arranged at backpack cover center；
Pre- hot-flow flue is made of preheating annular passage, air duct I and air duct II, and the setting of preheating annular passage is in backpack cover upper surface and around one
Circle, I one end of air duct connect with preheating annular passage, and the other end is shut, and II one end of air duct connects with preheating annular passage, separately
One end connects with dismounting boss；It is connected with wind channel tube on air duct I；Burner is detachably arranged on dismounting boss.
As a kind of preferred embodiment of the utility model, the dismounting boss is by dismounting boss flange and boss preheating circle
Pipe forms.
As a kind of preferred embodiment of the utility model, the backpack cover is made of backpack cover panel and skirtboard, below panel
Adhere to one layer of refractory cotton containing zirconium.
As a kind of preferred embodiment of the utility model, it is provided with connection I-steel on backpack cover panel, connects on I-steel
End face arranges that four pieces of backpack cover positioning plates, positioning plate are attached with rocking arm by bolt and nut.
The utility model structure design is optimized, and reasonable for structure, demolition and maintenance are conveniently.By roaster baking mistake
The waste heat diffused in journey heats the combustion air of wind turbine, improves the temperature of flame injection.Coal gas and fan combustion-supportincombustion wind exist
In burner when burning, gas drastically expands in narrow space, will produce powerful pressure, flame is just touched from burner and sent out
Come, generate very strong impact force, packet bottom can be baked to, reduces Bao Kou and wrap the temperature difference at bottom, be a kind of more satisfactory ladle
Roaster.
Description of the drawings
Fig. 1 is a kind of premix I. C. jetting formula mixed gas ladle baking facility backpack cover nozzle structure figure.
In figure, 1, backpack cover, 1-1, backpack cover panel, 1-2, backpack cover skirtboard, 2, dismounting boss, 2-1 dismantles boss flange, 2-
2, boss preheats pipe, 3, burner, 4, preheating annular passage, 5, air duct I, 6, air duct II, 7, wind channel tube, 8, connection I-steel,

Specific implementation mode
Below in conjunction with attached drawing and specific embodiment, the utility model is described in further detail.
As shown in Figure 1, including backpack cover 1, dismounting boss 2, pre- hot-flow flue and burner 3；Boss 2 is dismantled to be arranged in backpack cover panel
At the center of 1-1；Pre- hot-flow flue is made of preheating annular passage 4, air duct I 5 and air duct II 6, and the preheating setting of annular passage 4 is being wrapped
1 upper surface of lid and around one circle, I 5 one end of air duct with preheating annular passage 4 connect, the other end is shut, II 6 one end of air duct and
Preheating annular passage 4 connects, and the other end connects with dismounting boss 2；Wind channel tube 7 is connected on air duct I 5；The flange of burner 3
Disk is detachably connected with screw clearances hole by bolt and nut and the dismounting boss device 2 at 1 end of backpack cover.
The combustion air for originating wind turbine passes through from the inflow of wind channel tube 7, flows through air duct I 5, the gas in air duct I 5 is symmetrically by preheating
Annular passage 4 converges to air duct II 6, and burner combustion pipe, the umbrella shape with injection are arrived through burner 3 by the pre- hot air flow in air duct II 6
Coal gas air curtain is mixed and burned.
The dismounting boss 2 being arranged at the centers backpack cover panel 1-1, by boss preheating pipe 2-2, dismounting boss flange 2-1, spiral shell
Column fall off hole, connection bolt composition, burner 3 by have on upper ring flange screw clearances hole bolt and nut with dismounting boss dismantle
Bolt centering be bonded, wherein stud fall off hole aperture be more than bolt outer diameter.
Several connection I-steel 8 are set on backpack cover panel 1-1, and it is fixed that 8 upper surface of connection I-steel arranges four pieces of backpacks cover
