Description of drawings
In order to be illustrated more clearly in the utility model embodiment or scheme of the prior art, the below will do simple the introduction to the accompanying drawing of describing required use in embodiment or prior art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those skilled in the art, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the solar dryer that Fig. 1 provides for the utility model embodiment.
In above-mentioned Fig. 1: hothouse 1, exhaust outlet 2, bin gate 3, transparent cover plate 4, solar energy heat collector 5, bracing frame 6, the plate 7 of becalming.
The specific embodiment
The utility model provides a kind of solar dryer, under the prerequisite that is not needing the secondary energy sources input, reaches the effect of dried material.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Based on embodiment of the present utility model, all other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belong to the scope that the utility model is protected.
Please refer to Fig. 1, the structural representation of the solar dryer that Fig. 1 provides for the utility model embodiment.
The solar dryer that the utility model embodiment provides comprises:
The exhaust outlet 2 that is connected with hothouse 1, exhaust outlet 2 are used for realizing flowing of air, make hot-air through hothouse 1;
Heat collector, heat collector comprises solar energy heat collector 5 and is arranged at the transparent cover plate 4 of solar energy heat collector 5 outsides, transparent cover plate 4 can select that light transmittance is good, cheap material is made, as plastic sheeting, glass etc., transparent cover plate 4 is connected with hothouse 1, and reduces gradually to the other end near an end of hothouse 1.Transparent cover plate 4 can support by bracing frame 6.
In the solar dryer that the utility model provides, sunlight sees through transparent cover plate 4, shines on solar energy heat collector 5 for generation of heat, and forms air duct between transparent cover plate 4 and heat collector surface, is used for the hot-air that the circulation heat collector produces.Because hot-air density is low, upwards flow along air duct, hot-air carries out continuing upwards to flow after drying to material by hothouse, discharges by exhaust outlet.
The utility model is simple in structure, there is no rotating machinery, needs hardly it is safeguarded.Compact conformation, the hot-air that heat collector produces enters hothouse at once material is carried out drying, and the extra resistance that consumes is little, and has increased the power of Air Flow due to the swabbing action of exhaust outlet.It does not need the input of extraneous second energy, has reduced maintenance when reducing to consume yet, and on the other hand, if the forced flow that has blower fan to participate in can not guarantee the temperature of hot-air, certainly will reduce dry effect.And the air themperature of natural flow and flow velocity have definite relation, can guarantee dry quality.The utility model reaches the effect of dried material under the prerequisite that does not need energy input.
In the utility model one specific embodiment, exhaust outlet 2 is vertically arranged, to improve the flow effect of air.Solar energy heat collector 5 adopts the better and cheap material of absorbances to make, as selects the black plastic layer.Its effect is to absorb sunshine, adds hot-air, and impels Air Flow with this.
Solar energy heat collector 5 can be an overall structure, also can be a plurality of assembled.
Because hot-air natural flow power is little, natural wind is just larger on the impact of Air Flow in solar dryer, is necessary so at the air inlet place, the plate of becalming is set.The setting principle of plate of becalming is the impact that takes into account entrance friction and wind speed; The edge of heat collector can arrange expansion slot, facilitates the increase of heat collector area.
Hothouse 1 is actual in holding the utensil of required dried material, designed according to the concrete condition of actual drying material, the principle of design is the balance of taking into account between circulating resistance, heat exchange area and material turnover comfort level, can carry out diversified design according to concrete dried material.
The inside of exhaust outlet 2 arranges water leg, can discharge timely when conveniently having water droplet to be attached to inwall.The sunny slope of exhaust outlet 2 is also made by transparent material, and opaco is made by the thermal-arrest material, increases the area of thermal-arrest with this, increases drying capacity.Exhaust outlet can take several different methods to increase the height of exhaust outlet as long as guarantee not blank gas under normal pressure thus, also can be attached on towering buildings.
The height of exhaust outlet 2 and the area of heat collector can be selected according to actual conditions, and exhaust outlet is higher, and the area of heat collector is larger, and air themperature is just higher, and flowing velocity is just faster, and the ability of dried material is also just stronger.
In sum, the utlity model has following effect:
1, the solar dryer energy source is regenerative resource, national encourage growth;
2, construction cost is low, can be fixed, can be interim, also can increase the area of heat collector on fixed basis when the dry amount demand is large or increase the height of exhaust outlet;
3, device structure is simple, and flow process is short, and thermal losses is little; Can adjust hothouse according to the difference of dried material, applicable surface is very extensive;
4, the increase of the increase of heat collector area and exhaust outlet height is very convenient;
5, exhaust outlet can utilize existing pile, and to adhering to building without large detrimental effect, has further reduced the cost of solar energy solar dryer.
6, natural flow, drying quality is high, is particularly suitable for the special dry material that needs.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
