Description
Technical field
The present invention relates to a kind of crop greenhouse, particularly a kind ofly heat booth for flue-cured tobacco three-dimensional seedling raising.
Background technology
Along with cigarette industry was to the improve of raw tobacco material quality requirement in recent years, each producing region is optimized adjustment to culture technique, particularly on guarantee tobacco leaf growing stage, propose the concept of " transplant under film; transplant in advance, extend growing stage ", achieve certain effect through application.But mostly be early spring during China's cigarette transplantation of seedlings, ambient temperature is lower, as lower in transplanted temperature in advance, cigarette seedling plants that rear survival rate is not high, seedling-slowing stage is longer, therefore, wants to transplant in advance, must improve quality during cigarette transplantation of seedlings.
Current China flue-cured tobacco seedling-cultivating many employings booth floating seedlings mode, daytime, booth made its internal temperature higher by thermal-arrest, reduce due to ambient temperature in the evening, in canopy, heat loss causes its temperature lower, thus the temperature difference is larger sooner or later, as rainy weather, in canopy, temperature is all lower all day, North China, Central China Yan Qu are under extreme weather conditions, canopy temperature can be down to zero following appearance freeze phenomenon, the normal growth of serious obstruction cigarette seedling, the seedling raise period of prolongation tobacco, this and Production of Large Fields need to transplant early to contradict.Therefore, to nursery stage temperature comparatively Di Yan district, improve the most important condition that nursery temperature of shed is nurturing staff early.
It is more that current flue-cured tobacco seedling-cultivating booth heats research, the method such as Cold-proof Ditch, use multilayer cover layer is done to improve canopy temperature as adopted around seedling-cultivating tray support underlay thermal insulation layer, seedling pond, but said method is all subject to ambient temperature to be dominated, under different weather conditions, heat DeGrain; The methods such as also useful electrical heating in nearly 2 years, Boiler Steam heating, solar energy heating heat for booth, but drop into and operating cost larger.
Summary of the invention
The weak point that the present invention exists in order to avoid prior art, provides a kind of application and the fire-tube type temperature raising device in flue-cured tobacco three-dimensional seedling raising booth.
Technical solution problem of the present invention adopts following technical scheme:
Be applied to the fire-tube type temperature raising device in flue-cured tobacco three-dimensional seedling raising booth, its design feature is, described temperature raising device is made up of stove, radiator and drainage blower fan; Described radiator is arranged on the tobacco seedling-culturing dish frame bottom in booth, and its hot gas inlet is communicated with the outlet flue of stove by pipeline; Heat outlet is connected with drainage blower fan; Described radiator comprises many radiating tubes and multiple fire-box, and described fire-box is hollow cavity, and two ends are provided with pipeline connection port; Joined end to end by radiating tube between fire-box.
Design feature of the present invention is also:
Described radiator is fixed on tobacco seedling-culturing dish frame bottom by support.
Described stove forms stove body by shell, and described stove body is provided with fuel port, burner hearth and outlet flue, and the fuel port of described stove is located on the sidewall of stove body, and the outlet flue of described stove is located on the stove body sidewall relative with fuel port; Be provided with in described burner hearth and removablely add coal car.
The described coal car that adds is made up of the open-top frame of reinforcement welding and the pulley that is located at base of frame.
The described coal car that adds is provided with open top and sidepiece is uncovered, and described sidepiece is uncovered is provided with switching door.
Described fuel port is provided with fire door hinged with stove body; Described fire door is evenly provided with the adjustable air admission hole of multiple size.
The shell of described stove is made up of steel plate outer wall and refractory brick heat-insulation layer.
The described coal car that adds rolls with the slideway being arranged on burner hearth bottom and coordinates.
Radiating tube in described radiator and fire-box and between radiating tube and radiating tube, adopt interface to removably connect to slotting mode.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the booth thermal efficiency of the present invention is high, to heat speed fast.Because this equipment have employed the direct mode of heating of fire-tube type, decrease the heat exhaustion of intermediate medium, simultaneously, radiating tube and fire-box can adopt the metal material that thermal conductivity factor is higher, and increase drainage blower fan, improve the flow rate of hot gas in radiator, can radiating effect be significantly improved.Its thermal efficiency can reach 85%, to space 240m
3booth, per hourly heat 5 DEG C.
2, the present invention is simple, convenient.During use, open drainage blower fan, in stove, add ignited fuel.The speed that heats controlled by the injection rate and burning velocity controlling stove fuel with the steady temperature time.The control of burning velocity has mainly come by controlling burner hearth oxygen feeding amount, and the size that this equipment is opened by adjustment air admission hole controls burner hearth oxygen feeding amount.As used coal briquette to do fuel, operation is simpler, convenient, and stove disposablely can add 120 lump coal balls, under the environment of outside air temperature 0-4 DEG C, can make space 240m
3greenhouse temperature remain on about 15 DEG C, duration can reach 12 hours.
3, input of the present invention, use cost are low.Compared with other temperature raising device, input, use cost can reduce by 30%.
4, present device structure is simple, produces, installs simple and flexible, be convenient to batch production, the radiating tube in radiator and fire-box and adopt interface to removably connect to slotting mode between radiating tube and radiating tube, be convenient to install, dismounting, deashing.Meanwhile, can allocate flexibly, install according to the needs of temperature; Fire-box adds area of dissipation, improves the speed of heating.Simultaneously, that removably is freely arranged in pairs or groups between radiating tube and fire-box, can according to the size of Level temperature difference, the packing density of adjustment fire-box is (as little from the high-temperature region packing density close to hot gas inlet, large from the low-temperature space packing density close to blower fan), to reduce Level temperature difference, and then reach the object reducing the space temperature difference.Apply the booth of temperature raising device of the present invention, its canopy inner plane temperature difference is within 0.5 DEG C, and vertical temperature-difference is within 1.5 DEG C.
5, use safety of the present invention, easy to maintenance.In the installation of radiator with in using throughout the year, when causing hot gas leakage hidden danger when occurring connecting gap, can keep in repair or change radiating tube or fire-box at any time, avoiding working the mischief to plant growth; And present device employs drainage blower fan, in use, the air pressure in pipeline in negative pressure state, can not cause gas excessive compared with the external world.
