Description
Technical Field
The utility model relates to a device for providing hot air, in particular to a hot air furnace.
Background
The hot blast stove mainly uses coal, wood and the like as fuel, the fuel heats air after being combusted in a combustion chamber, and then hot air is provided for the wood drying equipment. The traditional hot blast stove is not reasonable in structural design and insufficient in heat exchange, so that the waste of fuel is inverted.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a hot blast stove with reasonable structural design, sufficient heat exchange and fuel saving.
The hot blast stove comprises a smoke outlet pipe, a cold air inlet pipe, an outer shell, a heat insulation layer, an inner shell, a stove pipe, a wind blocking sheet, a combustion chamber and a hot air outlet pipe, wherein the heat insulation layer is arranged inside the outer shell, the inner shell is arranged inside the outer shell, the wind blocking sheet is arranged between the outer shell and the inner shell, the wind blocking sheet is spiral, the cold air inlet pipe is arranged at the top of the outer shell, the smoke outlet pipe is arranged inside the cold air inlet pipe, the smoke outlet pipe is communicated with the inner shell, the stove pipe is arranged at the upper end of the inner shell, one end of the stove pipe is communicated with the cold air inlet pipe, the other end of the stove pipe is communicated with a gap between the outer shell and the inner shell, the combustion chamber is arranged at the lower end of the inner shell, one end of the hot air outlet pipe is communicated with a.
The heat-insulating layer is made of ceramic fiber cotton. The shell is a hollow cylinder. And a fireproof mud mixing layer is arranged on the inner wall of the combustion chamber.
The utility model has the advantages that: the fan sucks cold air and enters the furnace liner pipe from the cold air inlet pipe, hot smoke generated by the combustion chamber heats the cold air, waste gas is utilized, the wind shield is spiral, and the wind shield forms a spiral air inlet channel with the space between the outer shell and the inner shell, so that the contact time between air and the outer walls of the inner shell and the combustion chamber is longer, the heat exchange is more sufficient, and then the heated air is discharged from the hot air outlet pipe to drying equipment needing heat.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic front structural view of the present invention;
fig. 2 is a schematic sectional structure of the present invention.
Detailed Description
Referring to fig. 1 and 2, the hot blast stove comprises a smoke outlet pipe 1, a cold air inlet cylinder 2, an outer shell 3, a heat insulating layer 4, an inner shell 5, a stove liner pipe 6, a wind blocking sheet 7, a combustion chamber 8 and a hot air outlet pipe 9, wherein a fan 10 is installed on the cold air inlet cylinder 2, the wind blocking sheet 7 is also installed between the cold air inlet cylinder 2 and the smoke outlet pipe 1, the heat insulating layer 4 is installed inside the outer shell 3, the heat insulating layer 4 is made of ceramic fiber cotton or other suitable heat insulating materials, the heat insulating layer 4 can avoid heat loss and overheating of the outer shell 3, the inner shell 5 is installed inside the outer shell 3, the wind blocking sheet 7 is installed between the outer shell 3 and the inner shell 5, the wind blocking sheet 7 forms a spiral air inlet duct in the space between the outer shell 3 and the inner shell 5, so that the contact time between air and the outer walls of the inner shell 5 and the combustion chamber 8 is longer and the heat exchange is more sufficient, the cold air inlet, the smoke outlet pipe 1 is arranged in the cold air inlet barrel 2, the smoke outlet pipe 1 is communicated with the inner shell 5, the furnace pipe 6 is arranged at the upper end of the inner shell 5, one end of the furnace pipe 6 is communicated with the cold air inlet barrel 2, the other end of the furnace pipe 6 is communicated with a gap 11 between the outer shell 3 and the inner shell 5, the combustion chamber 8 is arranged at the lower end of the inner shell 5, a combustion chamber door 13 is arranged on the outer shell 3, the position of the combustion chamber door 13 corresponds to that of the combustion chamber 8, one end of the hot air outlet pipe 9 is communicated with the gap 11 between the outer shell 3 and the inner shell 5, and the other end of the hot air pipe 9 extends out of the outer shell 3. The shell 3 is a hollow cylinder, and the inner wall of the combustion chamber 8 is provided with a fireproof mud mixture layer 12. The fan 10 sucks cold air and enters the furnace liner 6 from the cold air inlet duct 2, hot smoke generated by the combustion chamber 8 heats the cold air, waste gas is used, the wind shield 7 is spiral, the wind shield 7 forms a spiral air inlet duct with the space between the outer shell 3 and the inner shell 5, the contact time of the air and the outer wall of the inner shell 5 and the combustion chamber 8 is longer, heat exchange is more sufficient, and the heated air is discharged from the hot air outlet duct 9 to drying equipment needing heat.
