Abstract
The invention provides an oblique bottom furnace which comprises a base, a furnace body, a plurality of coal gas burners, a coal gas pipeline, hot air pipelines, a flue, a heat exchanger and a chimney. The furnace body is erected on the base. A feed inlet is formed in the front end of the furnace body. A discharge outlet is formed in the rear end of the furnace body. The coal gas burners are arranged at the top of the rear section of the furnace body. Coal gas connectors and air connectors of the coal gas burners are connected with the coal gas pipeline and the hot air pipelines correspondingly. Flame outlets of the coal gas burners are aligned with the inside of the furnace body. The inside of the furnace body comprises a discharge section with a horizontal bottom surface and a conveying section with an oblique bottom surface. The discharge section is located at the inside rear section of the furnace body and below the coal gas burners. The conveying section inclines downwards from the feed inlet to the discharge outlet. The flue is connected to the top of the front end of the furnace body and communicates with the conveying section inside the furnace body. The flue comprises a flue vertical section and a flue transverse section extending backwards from the flue vertical section. The heat exchanger is installed in the flue transverse section. The tail end of the flue transverse section is connected with the chimney. The oblique bottom furnace saves energy and is environmentally friendly.
Description
Technical field
The present invention relates 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.
Content of the invention
For the deficiencies in the prior art, the present invention provides a kind of sloping hearth furnace, can make fuel using coal gas, and designs
So that pipe can be fully warmed-up, body of heater heat utilization efficiency is improved longer preheating section.The technical side that the present invention adopts
Case is：
A kind of sloping hearth furnace, including：Base, body of heater, coal gas burner, gas piping, hot-air duct, flue, heat exchanger, cigarette
Chimney；
Described body of heater is erected on base；The front end of body of heater is charging aperture, and rear end is discharging opening；
At the back segment top of body of heater, several coal gas burners are set；The coal gas interface of coal gas burner and air interface respectively with gas pipe
Road and hot-air duct connect；The flame hole be aligned 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, coal gas
Below burner；Conveying section is downward-sloping to discharging opening direction from charging aperture；
Flue is connected to body of heater front top, connects with the conveying section in body of heater；Flue includes a flue and erects section and from cigarette
The flue traversing section that section extends back is erect in road；Heat exchanger is arranged in flue traversing section；Flue traversing section end connects cigarette
Chimney；
The intake stack of sloping hearth furnace is connected with hot-air duct after heat exchanger.
Further, it is additionally provided with multiple material toggling holes in body of heater side.
Further, conveying section extreme direction to after body of heater at least extends to more than a coal gas burner position.
It is an advantage of the current invention that：
1）The material being heated can be advanced after automatically advancing or simply stirring；
2）Conveying section also serves as preheating section, and length is longer, and material can be made to make full use of flue gas heat preheating；
3）Fume afterheat makes full use of so that the air entering coal gas burner is preheated, energy saving.
4）Burning artificial coal gas, can obviously reduce air pollution.
Brief description
Fig. 1 is the body of heater transverse sectional view of the present invention.
Fig. 2 is the A-A of Fig. 1 to sectional view.
Fig. 3 is the B-B direction sectional view of Fig. 1.
Specific embodiment
With reference to concrete drawings and Examples, the invention will be further described.
The sloping hearth furnace that the present invention provides, as shown in Figure 1, Figure 2 and Figure 3, including：
