Description
Technical field
The present invention relates to a kind of tobacco seedling system.
Background technology
The floating seedlings work of tobacco all is the mid-March that is performed until next year mid-December since the first year every year; the nursery stage of nearly 3 wheat harvesting periods; this period, substantially between 0 to 15 ℃, the extreme temperature that often has about-5 ℃ occurred in the general temperature in south.And the preference temperature of tobacco seedling growth is 22 ℃-28 ℃, but under natural environment or in the general booth, key elements such as the temp. and humidity that need in the tobacco seedling growth process this period and illuminance are uncontrollable.Therefore, the cigarette seedling can not normally be emerged and grow, and high stem strong seedling cultivation rate is low, can not bring out strong sprout for transplanting at normal nursery stage, often cause seedling age long, the cigarette seedling is thin and weak, the transplanting after date pushes away, be transplanted to the land for growing field crops after the cigarette seedling be difficult to early growth and quick tiller, influence quality and the style characteristic of tobacco leaf.
On 09 26th, 2012, Chinese invention patent application publication number CN102687661A announced a kind of tobacco floating seed rearing strong seedling cultivation system.By booth part, heat part and booth general management department divides combination to form; Booth partly comprises the three-dimensional seedling raising frame in canopy body, the canopy body and heats nutrition pond module; Heating part is mainly connected to form by pipeline by hot water firing equipment, attemperater, booster pump, water knockout drum, recovery tank and circulating pump; This invention is adopted and is heated means, in the seedling raising process of cigarette seedling by whole-process automatic control, regulate key elements such as the temp. and humidity that needs in the tobacco seedling growth environment and illuminance are provided, build the grow up strong and sturdy growing environment of needs of a kind of suitable cigarette seedling.But it heats part is to adopt the hot-water boiler circulation heating, owing to heat the modularization distribution design in nutrition pond, the pipeline length that diversion box comes out has weak point, the restriction of insulation cost, causing heat nutrition pond module and the far-end of nearly diversion box end, to heat the module thermal losses of nutrition pond inconsistent, and the difficult temperature Centralized that realizes is evenly controlled.
Summary of the invention
In order to overcome above-mentioned defective, technical problem to be solved by this invention is: a kind of tobacco seedling system is provided.By reasonable laying pipeline with to the design of nursery pond science, realize homogeneous heating in the large tracts of land heating process; Build the grow up strong and sturdy growing environment of needs of a kind of suitable tobacco floating seed rearing seedling.
Technical scheme of the present invention is: a kind of tobacco seedling system comprises hot-water boiler, main-supply, main water return tube, circulating pump and a plurality of nursery pond arranged side by side; The hot-water boiler delivery port connects main-supply by the water supply circulating pump, main-supply branch again is connected on the interior heat exchange coil assembly feed water inlet of each nursery pond side by side, heat exchange coil assembly delivery port in each nursery pond is collected to main water return tube through compiling arm, and main water return tube returns the water return outlet that connects hot-water boiler again; One section same journey pipe that is equivalent to from first branch point to length between last branch point is arranged on the above-mentioned main-supply; Also connect an isocon between above-mentioned hot-water boiler delivery port and the water return outlet, a ratio adjusting valve is installed on this isocon; The control interface of temperature controller links to each other with actuator on the ratio adjusting valve; Described nursery pond is taked nutrition pond body, heat-barrier material, heat exchange coil assembly, nutrient solution filler, nutrient solution overfall and the integrated design of nutrient solution outlet; Design has three layers at the bottom of the pond of nutrition pond body; The bottom is heat-barrier material, and the intermediate layer is the anti-leak counterdie of band heat-reflecting layer, and the upper strata is the heat exchange coil assembly; There is the waterwall concrete on this body limit, nutrition pond, and the webmaster bracing frame is established in waterwall concrete top, lays main-supply, main water return tube on the frame and with the journey pipe; A feed pipe that connects the heat exchange coil assembly is provided with temperature control electromagnetic, and the highest point of a feed pipe is also established air bleeding valve.
Compared with the prior art, advantage of the present invention is: arrange with the journey pipe at main-supply, make the distance of the hot water that comes out from the hot-water boiler heat exchange coil in each nursery pond equate, thereby guaranteed each nursery pond thermal losses unanimity of different distances, the convenient temperature Centralized that realizes is evenly controlled, and then realizes homogeneous heating in the large tracts of land heating process.The webmaster bracing frame is established in the waterwall concrete top of nursery pond of the present invention, and the system that makes easily disposes, easily enforcement, easy to operate, is easy to realize modularization production and assembling.Anti-leak counterdie technology and the heat-barrier material of the employing band heat-reflecting layer at the bottom of the pond of nutrition of the present invention pond body guarantee that the heat of the overwhelming majority of heat exchange coil assembly passes to nutrient solution quickly and evenly, reduce thermal losses, realize energy-conservation.The present invention connects an isocon between hot-water boiler delivery port and water return outlet, the proportion of utilization control valve just can be realized the main-supply constant-temperature temperature-control; Constant temperature water tank and variable frequency pump cycle heat exchange loop have been omitted; Have simple in structurely, equipment cost is low, the characteristics that the thermal efficiency of heating system is high.With the journey technology, nursery pond is incubated temperature control technique, and the combination of the proportional valve control between hot-water boiler delivery port and the water return outlet by above-mentioned in the present invention, and three's synergy is mutually promoted, and finally reaches tobacco seedling pond temperature stabilization at 35 ℃; Build the grow up strong and sturdy growing environment of needs of a kind of suitable tobacco floating seed rearing seedling.
