Hot-blast stove of biomass energy source

[0019] Example

[0020] A biomass energy hot blast stove, comprising a furnace bridge 3, a furnace door 4, a shell 5, a smoke outlet 12, a feed door 13, a combustion bin 15, a fuel bin 17, an inner bladder 7 is arranged in the shell 5, The inner tank 7 is provided with a furnace bridge 3, a fuel tank 17, a combustion tank 15, a heat conductor 9, and a smoke exhaust port 12 from bottom to top; the lower part of the shell 5 is provided with a cold air inlet 2, an outlet of the blower 1 and a cold air inlet 2 is connected; the inner wall of the outer shell 5 and the outer wall of the inner liner 7 form a cold air cavity 6; the inner wall of the inner liner 7 forms a hot air cavity 8 with the outer walls of the heat conductor 9, the combustion chamber 15, and the fuel chamber 17; the upper wall of the inner liner 7 The inner tank air inlet 10 is provided on the upper part, the hot air outlet 18 is provided on the lower wall of the inner tank 7; the combustion chamber 15 is provided with a feed port, and the feed port is provided with a feed door 13, which requires heating The cold air is first sent into the cold air chamber 6 by the blower 1 from the cold air inlet 2 and the air is gradually preheated from bottom to top. Secondly, the preheated air enters the hot air chamber 8 from the air inlet 10 of the inner tank, and the air flows from top to bottom. It is gradually heated, and the heated air is discharged from the hot air outlet 18. The blower 1 is preferably a high-pressure blower. The heat conductor 9 is composed of a plurality of heat conduction pipes arranged vertically. The lower end of the heat conduction pipe is connected with the upper part of the combustion chamber 15 and the top of the heat conduction pipe communicates with the exhaust port 12. An oxygen supply 14 is provided in the middle of the combustion chamber 15. The structure of the oxygen supply 14 is a small through hole in the middle wall of the combustion chamber 15. The oxygen supply 14 sends a small amount of hot air from the hot air cavity 8 into the combustion chamber 15 Combustion. An exhaust fan 11 is provided at the exhaust port 12. Heat transfer fins 16 are provided on the outer walls of the combustion bin 15 and the fuel bin 17. Adjusting the inlet air size of the furnace door 4 or the feed door 13 controls the temperature of the hot air discharged from the hot air outlet 18. A temperature display sensor can be installed at the hot air outlet 18. The biomass energy hot air stove of the present invention needs to be matched with a corresponding drying device when used. The biomass energy hot air stove and drying device can also be installed in rural fields or yard dams or small cars to dry millet, corn, wheat and other crop products on site.
