Description

The counter-burning type coal-fired hot-blast stove
Technical field
The utility model relates to a kind of coal furnace technical field, relates in particular to a kind of counter-burning type coal-fired hot-blast stove that is used for green house of vegetables.
Background technology
In planting vegetable in greenhouse, especially winter, heating of green house of vegetables played crucial effects; But also there are many shortcomings in the hot-blast stove that the vegetable grower uses at present; Such as in use, need the people and constantly see stove, need not add a dant for a long time; Coal consumption is very big, and constantly carries out thermometric.There is hot-blast stove itself just can dispel the heat again, can influences the raising of the thermal efficiency if add insulation materials such as alumina silicate outside, and not be durable; If but not insulation, furnace body temperature can be very high, not only wasted heat but also can be crop is burned on every side; Cause damage, and hurt sb.'s feelings easily.
The utility model content
The utility model technical problem to be solved is: a kind of counter-burning type coal-fired hot-blast stove is provided, needs frequent coal, coal consumption big to solve hot-blast stove, and need that personnel nurse, the technical problem of waste of manpower resource.
For solving the problems of the technologies described above, the technical scheme of the utility model is: the counter-burning type coal-fired hot-blast stove comprises body of heater; Be provided with upper spacer and the lower clapboard arranged up and down in the cavity of said body of heater; Said upper spacer and lower clapboard are divided into the body of heater cavity successively combustion chamber, Heat Room and go out smoke-box from bottom to up, and the body of heater of said combustion chamber is provided with ash hole, and the body of heater of said Heat Room is provided with heat outlet; The said body of heater that goes out smoke-box is provided with outlet flue; Be provided with some heat exchanger tubes between said upper spacer and the lower clapboard, said heat exchanger tube runs through said Heat Room, said combustion chamber with go out smoke-box and be communicated with through said heat exchanger tube; Said body of heater is provided with the burner hearth adjacent with said body of heater outward, and the sidewall that said burner hearth and body of heater are adjacent is provided with into burner.
As a kind of improvement, the periphery of said burner hearth is provided with first interlayer, forms first cavity between said first interlayer and the burner hearth; The periphery of the combustion chamber of said body of heater is provided with second interlayer, forms second cavity between said second interlayer and the body of heater.
As further improvement; Said counter-burning type coal-fired hot-blast stove also comprises blower fan; The air inlet of said blower fan is communicated with said first cavity, and the air outlet of said blower fan is communicated with second cavity, and said second cavity is communicated with Heat Room through the passage that is arranged on the said body of heater.
Owing to adopted technique scheme, the beneficial effect of the utility model is: because burner hearth is arranged at the body of heater outside, and the burner hearth sidewall adjacent with body of heater is provided with into burner; Fuel is in when burning, flame can through advance burner in the combustion chamber internal combustion, rather than the sort of of traditional stove and accessory directly upwards burns; Make the coal seam realize burning in layer, thereby played the effect that is sparing in the use of coal, and can a large amount of coals of disposable adding; Coal seam burning in layer; Can not burn down for a long time, therefore can be for a long time without personnel's nurse, thus solved the problem of waste of human resource.
Because the periphery of body of heater and burner hearth all is provided with interlayer, has played insulation effect, has reduced thermal loss, has improved the utilization rate of coal of hot-blast stove, has further played the effect of economizing on coal.
Owing to be provided with blower fan, and blower fan is discharged to second cavity and goes from the first cavity air draught; And then leading to Heat Room, the heat that burner hearth is distributed siphons away, and has taken away the heat that distribute the combustion chamber; Add in the Heat Room simultaneously; Both reduce the temperature of interlayer, replenished the heat of combustion chamber again, played the effect of the recovery and reuse of heat.
