Abstract
The utility model discloses a circulation type efficient coal hot-air stove, comprising a base with a slag hole, a charging hole and a grate, a stove body, a flame tube, and a smoke vent, and the circulation type efficient coal hot-air stove is characterized in that a hot air cavity is arranged between the stove body and the flame tube, and the bottom part upward of the blast chamber is arranged in sequence laterally with a plurality of rows of heating pipes. The both ends of which are communicated with the hot air cavity, and the air duct fin is disposed on the outer wall of the flame tube. An air outlet is disposed on the bottom outboard of the stove body, and an air inlet is arranged on the upper outboard of the stove body. The air outlet is connected with a sirocco-sent chimney, and the extent of the sirocco-sent chimney can extend to be equal with the extent of the booth glasshouse. The utility model has the advantages that the calorific efficiency is high, the temperature rising is fast, the coal consumption is only 3-5 kg/h, in the 500 square meters booth, the temperature can be controlled between 8 DEG and 28 DEG, the temperature of the air outlet reaches highly about 90 DEG. With the features of the even output temperature, the fluency booth air, and the simple structure, the convenient operation, the utility model is suitable for using widely in the booth or in the glasshouse.
Description
Affiliated technical field
The utility model relates to the warming-up device technical field, and is specifically a kind of to plantation booth or heat in the greenhouse, the coal-fired furnace of damping.
Background technology
Along with economy and development of science and technology, booth or greenhouse have obtained use more and more widely in the north, such as the plantation of vegetables, melon and fruit, and nursery stock, flower culture, poultry, domestic animal survive the winter etc. and all to be unable to do without booth and greenhouse.At present, the warming-up device kind that booth and greenhouse adopt is many, as fuel oil, coal-fired hot-blast stove, and heating boiler and wall with flues etc.These firing equipments increase output for the temperature that improves in booth or the greenhouse, and important function has been brought into play in aspects such as shortening growth cycle.But, in existing these warming-up devices, the structure more complicated that has, the production cost height is promoted the use of the comparison difficulty; The programming rate that has is slow, and the hot air circulation of output is not enough, causes the temperature in the booth even inadequately, and air is smooth not enough, and the worm of falling ill is bred; The floor space that has is big, and the consumption coal is many, and the thermal efficiency is low.Because warming-up device is supporting inadequately, it is long to have influenced vegetables in booth or the greenhouse, flowers and fowl dirty swine to a certain extent, has also influenced the economic benefit of greenhouse gardening and breed.
Summary of the invention
In order to overcome the deficiency that warming-up device exists in existing booth or the greenhouse, the utility model provide a kind of simple in structure, production cost is low, floor space is little, quick heating, circulating efficient fuel coal hot-blast stove that the thermal efficiency is high.
The technical scheme that its technical problem that solves the utility model adopts is: this circulating efficient fuel coal hot-blast stove, comprise base and body of heater, flue and the exhaust opening of taking cinder notch, coal filling hole and grate out of, main points are to be provided with between said body of heater and the flue hot blast chamber, upwards laterally be provided with 1～5 row's heating tube successively and the two ends of every heating tube are connected with the hot blast chamber in the bottom, combustion chamber, the quantity of every row's heating tube setting is 2～6; Be provided with the air outlet that is communicated with the hot blast chamber in the outside of bottom of furnace body, be provided with in the outside of upper of furnace body be communicated with the hot blast chamber and with the air inlet of blower fan, on air outlet, connect and send thermal chimney, send the length of thermal chimney can extend to identical with the length of plastic greenhouse.
As a kind of improvement of the present utility model, in order to improve the effect of hot blast output, can on furnace outer wall, be provided with the choke fin that makes the hot blast chamber form spiral duct.
The utility model major advantage compared with prior art:
The one, thermal efficiency height, quick heating.Owing to upwards laterally be provided with 1～5 row's heating tube successively and the two ends of every heating tube be connected with the hot blast chamber in the bottom, combustion chamber; On furnace outer wall, be provided with simultaneously the choke fin that makes the hot blast chamber form spiral duct.Therefore, the hot-blast stove of this structure not only can make flue and heating tube produce a large amount of heats, but also a large amount of heats of its generation can be sent by heating tube and spiral duct, has improved the thermal efficiency of hot-blast stove greatly.After tested, the coal consumption of this hot-blast stove is lower, be 3～5kg/h only, but hot blast rate reaches 4500m
3About/h, the temperature of air outlet can be up to 90 ℃ about, such hot-blast stove can make 500m
2Temperature in the plantation booth is controlled between 8～28 ℃.
The 2nd, the temperature of output is even, air smoothness in the canopy.Owing on air outlet, be connected to and send thermal chimney, and make the length of sending thermal chimney extend to the length in booth or greenhouse about equally; Simultaneously be provided with air intake blower fan at air inlet.So conductive structure of this hot-blast stove, by the long thermal chimney that send, hot blast is sent from an end of booth, cold wind blows into forcibly from the hot-blast stove air inlet that is configured in the booth other end, make the air of booth under the effect of hot-blast stove, produce circulative convection, thereby temperature of shed is even, and the temperature difference at two ends is only between 1～2 ℃ in the booth.Because the air smoothness has reduced the generation of disease and pest in booth or the greenhouse effectively.
The 3rd, simple in structure, production cost is low, and floor space has only 1m
2About, manipulate more convenient, so can in booth or greenhouse, promote the use of widely.
