Summary of the invention
Problem to be solved in the utility model is to provide that a kind of thermal efficiency is high, cured effect is good, the baking oven of energy-conserving and environment-protective.
For solving the problems of the technologies described above, dome type baking oven of the present utility model comprises body of heater, and the body of heater top is provided with hemispheric dome, also comprises the chimney that is communicated with the body of heater inner chamber by the passage of heat; Be provided with on the described body of heater into coal channel, ash discharge passage and ventilation duct; The body of heater inner chamber is provided with and the fire grate that advances the coal channel coupling by bracing frame.
After having adopted technique scheme, fuel is added from advancing coal channel, in the body of heater internal combustion, the heat that produces distributes through furnace body outer wall, because the utility model has adopted hemispheric dome, thereby has increased its area of dissipation, improved radiating effect, when adopting the utility model to toast operation, can improve cured effect, possess the advantage of energy-conserving and environment-protective.
Further, dome type baking oven of the present utility model, the outer surface of its dome are welded with a plurality of dome fin.This structure further promotes heat radiation, and heat is fully used, and has improved cured effect.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Such as Fig. 1, Fig. 2 as seen, dome type baking oven of the present utility model comprises body of heater 1, and body of heater 1 top is provided with hemispheric dome 2, also comprises the chimney 5 that is communicated with body of heater 1 inner chamber by the passage of heat 3; Be provided with on the described body of heater 1 into coal channel 10, ash discharge passage 11 and ventilation duct 12; Body of heater 1 inner chamber is provided with and the fire grate 15 that advances coal channel 10 couplings by bracing frame 14.
Dome 2 is set to hemispherical, has increased itself and contact with air area, has improved radiating effect.
Advance on the coal channel 10 and be provided with coal feed point 100 by hinge, close at ordinary times, open when adding fuel.Be provided with ash hole 110 by hinge on the ash discharge passage 11, close at ordinary times, open during ash discharge.
Advance coal channel 10 and fire grate 15 couplings, during work, coal in bulk is added from coal feed point 100, be delivered to fire grate 15 along advancing coal channel 10, simple to operate.After the large coal cinder burning, coal ash is from fire grate 15 landing, and the operator draws out ashes through ash hole 110.The utility model loose coal that is applicable to burn, other bulk, non-shaped fuel also are applicable to burn.
In the utility model when work, be arranged on its main body in the barn, advances coal channel 10, ash discharge passage 11 is external, convenient operation.Ventilation duct 12 is external, is convenient to fresh air and enters.Chimney 5 overheads are outside barn, and the tail gas that burning produces is discharged thus.Body of heater 1, dome 2 to barn, are realized the baking operation with dissipation of heat.Combustion tail gas passage and dissipation of heat passage are isolated mutually, guarantee that baked article is not subjected to loose coal combustion to produce the pollution of gas.
As the embodiment of optimizing, the outer surface of dome 2 is welded with a plurality of dome fin 21, and further increasing heat radiation area has improved radiating effect, thereby improved the thermal efficiency of the present utility model.
Further, dome type baking oven of the present utility model is provided with heat abstractor 4 between its passage of heat 3 and the chimney 5.Heat abstractor 4 one ends are communicated with body of heater 1 inner chamber by the passage of heat 3, and the other end is connected to dome 2 tops by support arm 6.Chimney 5 is arranged on the end of heat abstractor 4.
Heat abstractor 4 comprises left passage 40, right passage 41, is provided with a plurality of warm-air pipes 42 between left passage 40 and the right passage 41.
Be provided with left channel outlet 400 by hinge on the left passage 40, be provided with right channel outlet 410 by hinge on the right passage 41, open it and can the warm-air pipe 42 of inside be checked and deashing.
Further, the utility model is provided with spiral heat dissipation sheet 421 at part warm-air pipe 42 outer surfaces.Spiral heat dissipation sheet 421 has increased area of dissipation greatly, has improved the baking operating efficiency.Particularly, warm-air pipe 42 is divided into multilayer to be arranged, and warm-air pipe 42 outer surfaces below the top layer are all with spiral heat dissipation sheet 421.
Further, body of heater 1 inner chamber comprises the combustion chamber 16 of upper end and the ash discharge chamber 17 of lower end, is provided with secondary ventilation pipe 13 along the outer wall of body of heater 1 between combustion chamber 16 and ash discharge chamber 17.These secondary ventilation pipe 13 two ends are respectively arranged with suitable for reading 130, end opening 130 ', suitable for reading 130 place in the combustion chamber 16, end opening 130 ' places in the ash discharge chamber 17, because ash discharge chamber 17 communicates with extraneous fresh air by ventilation duct 12, therefore secondary ventilation pipe 13 can further promote circulation of air, and then improves efficiency of combustion.
In the combustion chamber 16, be provided with fire-resistant ring 18 along body of heater 1 inner surface, its function is the burned damage of outer wall that prevents body of heater 1.
