Slideway is set in hot blast furnace shell, burner hearth is facilitated and must taken out so as to realize, with the product that must clean the inside easy in time
Ash, it also can more facilitate maintenance.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of indirect type fuel gas hot-blast stove, including hot blast furnace shell, cold wind import, burner hearth, heat-exchanging component, flue gas go out
Mouth, hot-blast outlet, blower fan, foot stool, the cold wind import is located at the bottom centre of the hot blast furnace shell, in the cold wind import
Side is provided with blower fan, and for the blower fan in fan house, the burner hearth is detachably arranged at the fan house by slideway
Top, the heat-exchanging component are connected with the burner hearth, and the exhanst gas outlet and the hot-blast outlet are located at the hot blast
The top of furnace shell, the exhanst gas outlet connect with the heat-exchanging component, from the cold wind that the cold wind import enters by heating
Exported from the hot-blast outlet, the hot blast furnace shell is on the foot stool.By setting slideway in hot blast furnace shell, just
Easy burner hearth must easily can be taken out, the convenient dust stratification cleaned inside burner hearth, be also more prone to that burning must be checked
Whether burner hearth damages, and when there is damage, must conveniently can be repaired.
More specifically, the slideway is resistant to elevated temperatures bearing slide rail.
More specifically, the burner hearth end is provided with dust filtering device, and the dust filtering device is high temperature resistant material
Material.Dust filtering device can keep off most dusts in burner hearth, so as to avoid dust from entering in heat-exchanging component.
More specifically, air filter is provided with the cold wind import.Air filter can allow the cold wind of entrance
It is cleaner.
More specifically, the heat-exchanging component includes the first heat exchange box, the second heat exchange box, the 3rd heat exchange box, and described first changes
Hot tank connects with second heat exchange box, and second heat exchange box connects with the 3rd heat exchange box.Heat exchange box can improve heat
Exchange rate.
More specifically, first heat exchange box is connected with second heat exchange box by the first heat exchanger tube.
More specifically, second heat exchange box is connected with the 3rd heat exchange box by the second heat exchanger tube and the 3rd heat exchanger tube
It is logical.
More specifically, hot blast furnace shell is provided with heat-insulation layer.
The beneficial effects of the utility model are that it is simple in construction, by setting slideway in hot blast furnace shell, it is possible to
It is easy burner hearth easily to be taken out, the convenient dust stratification cleaned inside burner hearth, also it is more prone to that burner hearth must be checked
Whether damage, when there is damage, must conveniently can be repaired.
