Description

A kind of solar energy bottom-heated drying shed
Technical field
What the present invention relates to is a kind of device utilizing solar energy drying material, particularly be utilize solar energy material to carry out the device of drying from bottom.
Background technology
The material that a lot of water content is large needs diminishing dry, the most generally drying of grain pellet, as the grain that cereal, corn, soybean, wheat etc. have just been gathered in the crops, these particles are all generally adopt the sun directly carrying out surperficial airing, but it is not directly high in the utilization rate of surperficial air dry method solar energy, because a large amount of sunray of drying grains surface reflection, the solar energy of being scattered and disappeared by reflection ray more than 40%, that is drying grain really absorb the solar energy of drying for raised temperature only some.Utilize solar energy to carry out surface to dry in the air an in addition shortcoming, that is exactly easily by the weather disruptions changed, once rain, whole drying plan just failure, also may cause moister, hold perishable loss consequence.People also made some solar dryers, produce higher temperature as utilized solar-energy light collector and carry out drying, but optically focused seasoning is the same effect with direct surface airing method, because although optically focused produces higher temperature, but the area of optically focused focus reduces a lot, and optically focused produces too high temperature and is also not suitable for drying.
Summary of the invention
In order to overcome general solar energy drying method drying objects poor efficiency, destroy large shortcoming by weather effect, my invention's one utilizes solar energy bottom-heated drying shed, it is dried from bottom object after absorbing the energy of solar energy, the utilization rate of solar energy increases widely, and the destruction of the anti-rainwater weather of energy is a kind of best solar drying device.
A kind of solar energy bottom-heated drying shed taked technical scheme of dealing with problems that utilizes is: one utilizes dry roof bottom solar energy to be that two light absorbing metal board plane composition surfaces become, metal sheet plane bottom is provided with water tank, the house floor of bottom also has heat drying metal sheet plane, water tank is also installed in bottom, the one side to lower header is connect after two cross current of upper water box, centre is also connected logical with water pipe with the another side of the water tank of bottom, flowing water switch in the other direction both sides water pipe is equipped with, the extinction plate on top absorbs solar energy after heating water and produces mobilization force, make the water generation exchange heat of lower box, the metallic plate of the bottom also evolution of heat carries out drying to object.
Utilize solar energy bottom-heated drying shed mainly to absorb solar energy as an energy of drying, its problem solved mainly contains two aspects: the absorption rate 1, improving solar energy; 2, avoid the material destroying and dry that rains, solve the meaning that these two subject matters are the inventions of solar energy dry materials room.The absorption rate improving solar energy is the growth requirement of flash baking or drying object doses, we carry out the absorption to solar energy with a metal cabinet, in-built for metal cabinet water inlet, allow the solar energy absorbed first carry out preheating to water, the water of high temperature has also just had the temperature energy of material drying.We utilize water to absorb the object of solar energy, because water is the material of shifting one's position that can flow, if we can flow down the high-temperature water that top absorbs solar energy from upper guide, so just can realize from bottom material drying, the light energy absorption casing on top can become again the roof of Changes in weather rain cover.The convective exchange realizing upper metal casing hot water and lower metal casing water at low temperature must have in one of them water tank water to mobilization force, and want two metal water casings to be connected.In order to produce water to mobilization force, we carry out slant setting the light energy absorption metal cabinet on top, this inclination makes the water height at metal cabinet two different, when water absorbs heat raised temperature, the water of some relatively-high temperatures hoists position up-flow, this generates the power of convection current, it is heavy that the water of the comparatively low temperature on top is squeezed downwards, if we are communicated with a water pipe vertically downward a bottom of a light energy absorption metal cabinet high position, the so squeezed water flowed down just thus water pipe flow down the oven dry metal cabinet arriving bottom, the too much moisture in bottom can by the connection water pipe of other end upwards convection current enter the lower position position of top light energy absorption casing, upwards convection current will be heated again very soon.
A kind of beneficial effect of solar energy bottom-heated drying shed that utilizes is: a kind of solar energy bottom-heated drying shed that utilizes utilizes upper and lower two metal cabinets to be built into the object drying room of a house shape, upper metal casing is utilized to absorb solar energy, utilize water as the medium of convection current transferring heat, realize inner drying material between drying materials, improve the utilization ratio of solar energy, Changes in weather can be avoided again to rain to the destruction of institute's drying objects, accomplished " shining paddy to rain and need not receive ".
