Background technology
Flue-cured tobacco technology and equipment backwardness is a development of restriction cured tobacco production and a great difficult problem that influences farmer richness.The present tobacco flue-curing house of tobacco grower's widespread usage, heat lean on be a kind of as northeast big a heatable brick bed mode of heating, at subsurface with brick one-tenth flue, pyrotechnics passes in flue, heating flue is dried tobacco leaf again, uses this furnace drying method, and a large amount of heats are discharged into aerial or scatter and disappear underground, therefore, the flue-cured tobacco cycle long (a roasting room cigarette needs 7-9 days), consumption coal many (15 mu of flue-cured tobacco consumption coal 8-9 tons), flue cured tobacco quality is poor, the cigarette valency is low, and also frequent breaking out of fire brings heavy losses to the tobacco grower.Existing several flue-cured tobacco stove, the hot blast that flue-cured tobacco adopted all is disposable utilization, behind the air cooking tobacco leaf, is being with a large amount of waste heats to be discharged in the air, waste and can not reuse, therefore, and existing several flue-cured tobacco stoves, power consumption is big, and the consumption coal is many.
The concentrated type hot blast stove for flue-cured tobacco of my institute development, it is low to have a power consumption, motor 370W (above-mentioned flue-cured tobacco stove motor 2200W, be our 6 times, only this item tobacco grower will spend more 1300 yuan in 1 year), consumption coal low (be above-mentioned flue-cured tobacco stove 2/3rds), quick heating, flue-cured tobacco is of good quality, the advantage of handling safety.
Summary of the invention
Goal of the invention of the present utility model is for providing a kind of energy consumption low, and heat supply is even, shortens the concentrated type flue-cured tobacco stove in flue-cured tobacco cycle.
Realize that foregoing invention purpose technical scheme is as follows:
A kind of concentrated type flue-cured tobacco stove, by the concentrated type tobacco flue-curing house, pressure fan, the special-purpose stove of flue-cured tobacco, the balanced distribution system of air feed triplate line and hot blast is formed, wherein the top of the special-purpose stove of flue-cured tobacco is connected with pressure fan, pressure fan is connected with the concentrated type tobacco flue-curing house by the air feed three-way pipe, the air feed three-way pipe connects concentrated type tobacco flue-curing house end and is provided with hot blast import plate, the 3rd port of air feed triplate line is provided with cold wind import plate, ajutage is connected the special-purpose stove of flue-cured tobacco bottom by ring flange with averaging wind pipe in the concentrated type tobacco flue-curing house, be welded with blowpipe on the averaging wind pipe equably, concentrated type tobacco flue-curing house air feed three-way pipe one upper lateral part has the humidity discharging mouth.
Sloping, concentrated type tobacco flue-curing house ground face, from special-purpose stove one end of flue-cured tobacco from low to high to the other end.
The balanced distribution system heat supply of hot blast is even, and the tobacco leaf in the concentrated type tobacco flue-curing house is evenly dried, and its structure is that ajutage one end joins with ring flange and averaging wind pipe, and blowpipe is welded on the averaging wind pipe uniformly, and blowpipe keeps certain length.The other end of blowpipe joins with ring flange and hot-blast stove.The air feed three pass system is provided with hot blast import plate for the air feed three-way pipe connects concentrated type tobacco flue-curing house one end, and a relative end is connected with pressure fan, and the 3rd perpendicular port is provided with cold wind import plate.
The process of carrying out flue-cured tobacco with the utility model is: through the hot blast of hot-blast stove heating, after tobacco flue-curing house inner drying tobacco leaf circulates a week, send into hot-blast stove by pressure fan again, the hot blast after the heating enters circulation baking tobacco leaves in the tobacco flue-curing house again again.
Compared with prior art the beneficial effects of the utility model are:
1. the hot blast in the tobacco flue-curing house recycles repeatedly, and heat energy obtains fully effectively utilizing, thereby cuts down the consumption of energy 1/3rd.
2. hot blast is through the distribution of averaging wind pipe, and heat supply is even, has guaranteed oven dry evenly, guarantees that quality of tobacco improves 4-6 grade, same tobacco leaf, owing to improved credit rating, the tobacco grower takes in and has improved 20%-30%.
3. employing the utility model makes the 2.2kw/h of power consumption by other type of furnaces, reduces to 0.37kw/h, reduces power consumption 83%.
Description of drawings
Fig. 1 is the utility model concentrated type hot blast stove for flue-cured tobacco structural representation view;
Fig. 2 is the plan structure schematic diagram of the utility model concentrated type hot blast stove for flue-cured tobacco Fig. 1.
The specific embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments.
By among Fig. 1 and Fig. 2 as can be seen, concentrated type flue-cured tobacco stove, by the concentrated type tobacco flue-curing house, pressure fan, the special-purpose stove of flue-cured tobacco, the balanced distribution system of air feed triplate line and hot blast is formed, wherein the top of the special-purpose stove 4 of flue-cured tobacco is connected with pressure fan 2, pressure fan 2 is connected with concentrated type tobacco flue-curing house 19 by air feed three-way pipe 5, the air feed three-way pipe connects 5 connection concentrated type tobacco flue-curing houses, 19 ends and is provided with hot blast import plate 3, the 3rd port of air feed triplate line 5 is provided with cold wind import plate 6, ajutage 9 is connected the special-purpose stove of flue-cured tobacco 4 bottoms by ring flange with concentrated type tobacco flue-curing house 19 interior averaging wind pipes 10, be welded with blowpipe 20 on the averaging wind pipe equably, concentrated type tobacco flue-curing house 19 air feed three-way pipes one upper lateral part has humidity discharging mouth 18.Concentrated type tobacco flue-curing house ground 13 sloping faces, from special-purpose stove 4 one ends of flue-cured tobacco from low to high to the other end.
Changing yellow stage and fixation stage at tobacco leaf drying, need certain temperature and humidity in the barn, in concentrated type tobacco flue-curing house 19, tobacco leaf 15,16,17 intensive extruding are hung into three layers, and cold wind import plate 6 is closed, hot blast import plate 3 is open, humidity discharging mouth 18 is closed, and hot blast 11 is lowered the temperature after tobacco flue-curing house inner drying tobacco leaf circulates a week, sends into hot-blast stove 4 by pressure fan 2 again, hot blast 11 after the heating enters circulation baking tobacco leaves in the concentrated type tobacco flue-curing house 19 again again.Hot blast is through the super-dry tobacco leaf, and cooling is heated again, dry again tobacco leaf, and cooling again, heating recycles so repeatedly again, and the waste heat of hot blast is not wasted at all, has saved energy consumption greatly.Drying muscle stage at tobacco leaf drying, need a large amount of humidity dischargings, at this moment open cold wind import plate 6, hot blast plate 3 is closed, and humidity discharging mouth 18 is open, cold wind 7 through triplate lines 5, pressure fan 2, special-purpose stove 4 heat exchange of flue-cured tobacco become hot blast 12, through ajutage 9, averaging wind pipe 10, blowpipe 20 enters concentrated type tobacco flue-curing house 19, again by the afterbody of concentrated type tobacco flue-curing house 19 to the cocycle baking tobacco leaves, at last a large amount of moisture are entered in the atmosphere through humidity discharging mouth 18.Because averaging wind pipe 10, blowpipe 20 has guaranteed the uniformity of heat supply and the uniformity of oven dry, makes the quality of tobacco leaf improve 4-6 grade, and income has improved 20%-30%.In the dried muscle later stage, drying tobacco is shunk, and forms the space between the tobacco leaf, and hot blast 14 circulates between tobacco leaf, has quickened the drying of tobacco leaf.Hot blast stove for flue-cured tobacco is seated on the brick ashes thorax 8, and flue gas enters via chimney 1 in the air.
