Abstract
The invention discloses a circular electric warming oven for a greenhouse. The circular electric warming oven comprises an oven body and an electric oven heating room; a shell of the oven body is in a double-layer hollow structure; and the oven body internally comprises a plurality of temperature-resistant steel pipes communicated with the opposite shell. When the electric warming oven works, cold air is continuously input into the hollow shell of the oven body at an air inlet, and the cold air circularly comes in and out of the shell and the heated steel pipes, is quickly heated through effective heat exchange, and is continuously sent into an exterior from an air outlet after entering a heat collecting room, so that the purposes of temperature rise and heat preservation are realized for a shed room. By using the circular electric warming oven, the separation of the cold air and from hot air is guaranteed; the direct heat exchange cannot occur; therefore, the heating efficiency can be greatly improved; furthermore, the heating way is simple; the floor area is small; and the cost is low.
Description
Technical field
The present invention relates to the circulating electric heater in a kind of greenhouse, belong to the horticultural facility field.
Background technology
In recent years greenhouse by solar heat development of the northern area of China area is very fast, become one of main channel that increasing peasant income get rich, but northern China most areas minimum temperature cold season in winter is all below minus 20 degrees, hothouse production through winter facts have proved, the ability that greenhouse by solar heat is resisted the cold grade of low-temperature frozen diastrous weather is limited, although daylight accumulation of heat, but the decline of nocturnal temperature can cause time after midnight indoor temperature generally can only keep about 2-5 ℃, if cold wave is arranged, and then temperature is lower, very harmful to crop growth, cause the vegetables in day-light greenhouse growth to be hindered in various degree, particularly fruit vegetables is difficult to normally bloom bear fruit, and has a strong impact on the production ﹠ marketing supply.
Existing heating system is used in the prior art, but adopts simple Steam Heating or boiler heating more, and floor space is large and cost is high, is not suitable for adopting in the greenhouse.Indivedual hot-blast stoves that adopt, heat exchange is less, and efficient is low, and cost is high.
Summary of the invention
For addressing the above problem, the invention provides the circulating electric heater in a kind of greenhouse, can realize temperature raising and maintaining, can realize energy-saving and environmental protecting again.
The circulating electric heater in a kind of greenhouse, comprise body of heater, heating by electric cooker chamber, the shell that it is characterized in that described body of heater is the double layer hollow structure, the outer shell wall bottom of described shell one side has air inlet, described body of heater inside comprises the heatproof steel pipe of some connection offside shells, described body of heater shell upper space is that heat gathers the chamber, and has air outlet in a side.
Width is 50mm between the preferred described shell bilayer, and the body of heater height is 550mm, width 400mm.
Preferred described air inlet diameter is 75mm, described air inlet place configuration fan blower.
Preferred described steel pipe is two-layer, every layer three row, up and down two-layer cross arrangement.
The invention effect:
This electric heater is when work, constantly cold air is inputted the hollow shell of body of heater after the preheating at the air inlet place, the cold air discrepancy that in shell and heated steel pipe, circulates, heat up rapidly by effective heat exchange, enter and constantly be admitted to the outside by air outlet after heat gathers the chamber, other hot channel in the preferred communication chamber, the indoor radiating pipeline is sent to every nook and cranny, canopy chamber to the hot gas after heating up uniformly, makes the canopy chamber reach the purpose of temperature raising and maintaining.
Because cold air is introduced into hollow shell and enters heated steel pipe again, therefore guaranteed the separation of cold and hot air of starting stage, direct heat exchange can not occur immediately, simultaneously also can carry out certain preheating to cold air, therefore can significantly improve the efficiency of heating surface, and mode of heating is simple, and floor space is little, and cost is low.
Adopt electrical heating, can guarantee the clean and tidy environmentally safe of environment.
The application of efficient energy-saving circulating electric heater can make northern area greenhouse minimum temperature raising in winter 8-10 degree, has solved the very difficult difficult problem of normally blooming and bearing fruit of fruit vegetables in the northern greenhouse.
Description of drawings
Fig. 1 is the schematic diagram of the circulating electric heater embodiment in greenhouse;
Each label lists as follows among the figure:
The 1-body of heater, 2-heating by electric cooker chamber, the 3-shell, the 4-air inlet, the 5-steel pipe, the 6-heat gathers chamber, 7-air outlet.
Embodiment
The present invention the present invention is further explained below in conjunction with the drawings and specific embodiments in order better to explain.
Present embodiment is the circulating electric heater in a kind of greenhouse, comprises body of heater 1, heating by electric cooker chamber 2, the height 550mm of described body of heater 1, width 400mm, and volume is little, the use in the suitable greenhouse.The shell 3 of described body of heater 1 is the double layer hollow structure, and thickness of interlayer 50mm, the outer shell wall of described shell 3 one sides have the air inlet 4 that diameter is 75mm, air inlet 4 places configuration fan blower.Described body of heater 1 inside comprises the heatproof steel pipe 5 of two-layer connection offside shell, every layer three row, up and down two-layer cross arrangement. described body of heater 1 shell 3 upper spaces are that heat gathers chamber 6, and have air outlet 7 in a side.
Present embodiment is when work, the hollow shell 3 of body of heater is constantly inputted cold air in preheating at air inlet 4 places after 15 minutes, the cold air discrepancy that in shell 3 and heated steel pipe 5, circulates, heat up rapidly by effective heat exchange, enter and constantly be admitted to the outside by air outlet 7 after heat gathers chamber 6, other hot channel in the communication chamber, indoor radiating pipeline are sent to every nook and cranny, canopy chamber to the hot gas after heating up uniformly, make the canopy chamber reach the purpose of temperature raising and maintaining.
The safe agricultural planting of 2011-2012 Beijing centre for spreading and Beijing Yuan Feng cooperative society utilizes the equipment of above-described embodiment to test in western Shao Qu village, Miyun Xi Shaoqu town, the result shows: every mu of contrast of cucumber increases by 1650.6 kilograms, every mu of contrast of tomato increases by 2010 kilograms, every mu of contrast of custard squash increases by 1815.5 kilograms, plants average every mu of fruit vegetables and increases income 5800.9 yuan.
