Description
Technical field
The utility model is related to hot air furnace device field, especially a kind of hot-blast stove with the pre- hot function of air inlet.
Background technology
Hot-blast stove is a kind of usual means in the industrial production, is chiefly used in industrial products heat treatment binder removal.In heat
After external normal temperature air is entered by air inlet pipe in hot-blast stove during the use of wind furnace, due to existing with the high-temperature gas in stove
The larger temperature difference, it is thus possible to will appear the case where sintered products deform upon cracking due to hot and cold air conflict.
Therefore, one preheating device need to be installed in air inlet pipe position during actual sintered, the preheating device is outer at present
Portion, which adds, to be heated up by other heat sources, therefore, not only complicated, cause to increase cost, can also consume additional energy
Source.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable for structure, the saving energy, and have
There is the hot-blast stove of the pre- hot function of air inlet.
The utility model is achieved through the following technical solutions：
A kind of hot-blast stove with the pre- hot function of air inlet, including furnace body shell are equipped with furnace body in the furnace body shell
Inner casing is wrapped around electric heating flue on the outside of the furnace body inner casing, which is circumscribed with external power supply, the furnace body inner casing
Upper end escape pipe is connected with by upper end cover, the lower end of the furnace body inner casing is communicated with air inlet pipe, it is characterised in that：In the stove
Furnace body coil pipe is installed, which is coated on the outside of electric heating flue, institute in the gap between body case and furnace body inner casing
The outlet end for stating furnace body coil pipe is connected with air inlet pipe coil pipe by connector, which is coated on the outside of air inlet pipe, described
The outlet end of air inlet pipe coil pipe is communicated with external liquid storehouse, which is connected with the liquid feeding end of furnace body coil pipe, in the liquid storehouse
It is equipped with heat-exchange working medium.
The advantages of the utility model and good effect are：
In the utility model, the furnace body coil pipe installed between furnace body shell and furnace body inner casing is for generating electric heating flue
Waste heat export, and by the air inlet pipe coil pipe of connection by heat derives to air inlet pipe position, to improve outside air inlet pipe
Temperature plays the role of preheating the air for flowing through air inlet pipe, is not necessarily to other heating equipments, simple in structure, functional；
In addition, by the pipeline for the outside being connected with air inlet pipe coil pipe and furnace body coil pipe, it can also be by waste heat for heating or other necks
In domain, energy-saving and environment-friendly effect is further functioned as, finally, by the various heat exchange working medium in more liquid changing chamber, can also meet sintering
The requirement of different product, wide adaptability.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
It elaborates to the utility model below by embodiment, the embodiment is illustrative instead of limiting
, protection scope of this utility model cannot be limited by this.
A kind of hot-blast stove with the pre- hot function of air inlet, including furnace body shell 4 are equipped with furnace body in the furnace body shell
Inner casing 10 is wrapped around electric heating flue 11 on the outside of the furnace body inner casing, which is circumscribed with external power supply, the furnace body
The upper end of inner casing is connected with escape pipe 1 by upper end cover 2, and the lower end of the furnace body inner casing is communicated with air inlet pipe 8, the utility model
Innovation is, furnace body coil pipe 5 is equipped in the gap between the furnace body shell and furnace body inner casing, which is coated on
The outlet end in the outside of electric heating flue, the furnace body coil pipe is connected with air inlet pipe coil pipe 7 by connector 6, the air inlet pipe coil pipe packet
It overlays on the outside of air inlet pipe, the outlet end 3 of the air inlet pipe coil pipe is communicated with external liquid storehouse, the feed liquor in the liquid storehouse and furnace body coil pipe
End is connected, and the liquid storehouse is built-in with heat-exchange working medium.
In the present embodiment, insulation shell 9 is installed on the outside of electric heating flue, the stove is installed on the outside of the insulation shell
Body disc pipe.
The use process of the utility model：
When the utility model is used, electric heating flue connection external power supply generates heat in turn, in heating furnace body inner housing inner
While, the heat-exchange working medium recycled in furnace body coil pipe can also be heated, air inlet is flowed into during heat-exchange working medium recycles
Pipe dish pipe position, the air to flow through air inlet pipe carry out heat temperature raising.
