Description
Technical field
The utility model is related to a kind of industrial furnace, especially a kind of sloping hearth furnace.
Background technology
Sloping hearth furnace is widely used in the heating of pipe blank link of steel pipe；
Traditional sloping hearth furnace heat utilization efficiency is relatively low, and it often makees fuel using fine coal, and thermal effect is low and air pollution is big.
The content of the invention
For the deficiencies in the prior art, the utility model provides a kind of sloping hearth furnace, can make fuel using coal gas, and
Devise longer preheating section so that pipe can be fully warmed-up, body of heater heat utilization efficiency is improved.The utility model is used
Technical scheme be：
A kind of sloping hearth furnace, including：Base, body of heater, coal gas burner, gas piping, hot-air duct, flue, heat exchanger,
Chimney；
The body of heater is erected on base；The front end of body of heater is charging aperture, and rear end is discharging opening；
Several coal gas burners are set at the top of the back segment of body of heater；The coal gas interface and air interface of coal gas burner respectively with coal
Feed channel and hot-air duct connection；The flame hole alignment furnace interior of coal gas burner；
Furnace interior includes the discharging section of bottom surface level and the conveying section of inclined bottom surface；Discharging section is located at back segment in body of heater,
Below coal gas burner；Conveying section is tilted down from charging aperture to discharging opening direction；
Flue is connected to body of heater front top, is connected with the conveying section in body of heater；Flue include flue erect section and
The flue traversing section that section extends back is erect from flue；Heat exchanger is arranged in flue traversing section；Flue traversing section end connects
Cigarette receiving chimney；
The intake stack of sloping hearth furnace after heat exchanger with hot-air duct by being connected.
Further, multiple material toggling holes are additionally provided with body of heater side.
Further, conveying section at least extends to more than one coal gas burner position to extreme direction after body of heater.
The utility model has the advantage of：
1）The material heated is advanced after can automatically advancing or simply stir；
2）Conveying section also serves as preheating section, and length is longer, may be such that material makes full use of flue gas heat to preheat；
3）Fume afterheat is made full use of so that the air for entering coal gas burner is preheated, and saves the energy.
4）Burn artificial coal gas, can obviously reduce air pollution.
Brief description of the drawings
Fig. 1 is body of heater transverse sectional view of the present utility model.
Fig. 2 for Fig. 1 A-A to sectional view.
Fig. 3 is Fig. 1 B-B direction sectional view.
Embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
The sloping hearth furnace that the utility model is provided, as shown in Figure 1, Figure 2 and Figure 3, including：
Base 1, body of heater 2, coal gas burner 3, gas piping 4, hot-air duct 5, flue 6, heat exchanger 7, chimney 8；
The body of heater 2 is erected on base 1；The front end of body of heater 1 is charging aperture 201, and rear end is discharging opening 202；
Several coal gas burners 3 are set at the top of the back segment of body of heater 2；Coal gas interface and the air interface difference of coal gas burner 3
It is connected with gas piping 4 and hot-air duct 5；Inside the flame hole alignment body of heater 2 of coal gas burner 3；
The inside of body of heater 2 includes the discharging section 203 of bottom surface level and the conveying section 204 of inclined bottom surface；Discharging section 203 is located at stove
Back segment in body 2, the lower section of coal gas burner 3；Conveying section 204 is tilted down from charging aperture 201 to the direction of discharging opening 202；Conveying section 204
Extreme direction at least extends to more than one position of coal gas burner 3 after to body of heater 2；
Flue 6 is connected to the front top of body of heater 2, is connected with the conveying section 204 in body of heater 2；Flue 6 includes a flue and erected
Vertical section 601 and the flue traversing section 602 extended back from flue setting section 601；Heat exchanger 7 is arranged on flue traversing section 602
In；The end of flue traversing section 602 connects chimney 8；
The intake stack of sloping hearth furnace（It is not drawn into figure）By being connected after heat exchanger 7 with hot-air duct 5；Can be fully sharp
The air for entering coal gas burner 3 is first heated with the waste heat in flue gas, the energy can be saved；
Pipe is slided backward or rolled along inclined conveying section 204 from after entering in body of heater 2 charging aperture 201 naturally；Pipe
In conveying 204 traveling process of section, also constantly preheated by hot-fluid；Therefore when pipe marches to 3 lower section of coal gas burner,
Higher temperature is already had, can be with gas saving；
In addition, multiple material toggling holes 9 are additionally provided with the side of body of heater 2, for stirring the pipe in body of heater 2 by instrument.
