The traditional tube group type hot-blast stove that does not belong to core structure in addition in addition, weak point are that high material consumption, service life are short.

Summary of the invention

The utility model is big at the existing above-mentioned volume of existing cartridge type metal fever wind furnace, energy consumption is high, the weak point that complex structure, manufacturing cost height, power consumption are big, service life is short, provide that a kind of volume is little, energy consumption is low, simple in structure, low cost of manufacture, power consumption are low, two adverse current highly efficient durable metal fever wind furnaces of long service life.

The technical solution adopted in the utility model is finished in the following way: two adverse current highly efficient durable metal fever wind furnaces adopt the low flow velocity of low temperature, two countercurrent heat exchange principles of high-temperature high-flow rate, it comprises thick dirt expansion chamber, the combustion chamber, heat exchanger, two to eight fan-shaped flues, the plume dispensing head, smoke exhaust pipe, wherein, heat exchanger adopts four layers of tubular structure, be respectively equipped with hot-flow flue from the inside to the outside, annular smoke flue and cold air duct, the combustion chamber is positioned at the heat exchanger below, thick dirt expansion chamber is positioned at the below of combustion chamber, be provided with secondary wind air intake endless tube in the outside, combustion chamber, on the inwall of secondary wind air intake endless tube, be provided with secondary wind air intake arm, the heat exchanger bottom is respectively equipped with fire door, hot-blast outlet and last exhaust opening, be provided with the cold wind import between heat exchanger and the thick dirt expansion chamber, on thick dirt expansion chamber, be respectively equipped with the down smoke-discharging mouth, get the dirt door, thick dirt storage chamber, thick dirt inlet, get the ash door, below hot-blast outlet, be provided with airduct, fan-shaped flue and plume dispensing head are located at the heat exchanger top, wherein two to eight fan-shaped flues be distributed on the plume dispensing head around, be provided with smoke hatch at each fan-shaped flue top, be provided with interface at the top of plume dispensing head, in the endoporus of last interface, be provided with the valve of control flue gas flow direction, last exhaust opening, the down smoke-discharging mouth reaches upward, and interface all joins with smoke exhaust pipe.When two adverse current highly efficient durable metal fever wind furnaces are lit a fire, open and be located at the valve in the interface endoporus on the plume dispensing head top, allow flue gas directly discharge through smoke exhaust pipe by the last interface at plume dispensing head top.When two adverse current highly efficient durable metal fever wind furnaces are worked, close and be located at the valve in the interface endoporus on the plume dispensing head top, the smoke hatch, annular smoke flue, last exhaust opening and the down smoke-discharging mouth that allow flue gas pass through fan-shaped flue are discharged through smoke exhaust pipe.

The two adverse current highly efficient durable metal fever wind furnaces of the utility model are compared with existing cartridge type metal fever wind furnace, have that volume is little, the thermal efficiency is high, energy consumption is low, power consumption is low, annular smoke flue is difficult for stifled dirt, the discharge capacity of flue dust is little, the dust stratification that cleans flues convenient and the characteristics of long service life.The utility model is particularly suitable as and is applied to tealeaves, food, medicinal material, timber stoving, the metal fever wind furnace in fields such as industrial chemicals, paper drying, domestic birds and animals heating and warehouse article protection against the tide.
