The utility model is characterized in that the wall body is provided with a cold air airflow chamber and a heat exchanger; the cold air airflow chamber is connected with a cold air inlet; the heat exchanger is composed of a hot air ariflow chamber; the heat exchanger is connected with a hot wind outlet. The utility model can utilize solar energy to heat airflow and carry out baking indoor articles which are used for drying, and meanwhile, the utility model can heat hot water. Thus, utility model can fully utilize solar energy and conserve heat energy for improving heat utilization rate. The utility model can be a baking apparatus with high heat efficiency, no energy consumption, or little energy consumption, complete functions, and wide purposes.

Description

A kind of solar energy barn

The utility model relates to a kind of apparatus for baking, especially a kind of apparatus for baking that utilizes solar energy flue-cured tobacco, grain and cotton crops and seed, medicinal material, timber or other agricultural byproducts etc. to be carried out drying or dehydration processing.

In the season of grain and other crops results, what allow vast farmers load disturbs most is exactly the problem of shining the grain difficulty, especially concerning the peasant of mountain area or upper level, owing to be subjected to the restriction in place, it is impossible in a short time the grain of gathering in the crops all being dried, so the peasant on close highway limit haves no alternative but to place it in and carries out airing on the highway, thereby cause highway along the line because of shining the various traffic problems that grain causes.In order to solve the problem of shining the grain difficulty, people work out many roasting plants, and wherein, drying room is comparatively general a kind of.But existing drying room mainly is to provide heat energy by coal-fired or combustion bavin, and this brings a series of problems such as consuming ample resources again, and purposes is single, and therefore poor performance, still can not adapt to efficient, low energy, multiduty modern life requirement.

The purpose of this utility model is to provide a kind of and efficiently, does not consume energy or few power consumption, purposes is wide, function is complete solar energy barn.

The technical solution of the utility model is: it comprises body of wall, be located at the hothouse in the body of wall, be located at the weep hole at hothouse top and be located at air supply line on the body of wall, it is characterized in that body of wall is provided with the heat exchanger that is made of solar thermal collector and flow of cooled air chamber that links to each other with cold air inlet and the hot air flow chamber that links to each other with hot-blast outlet.Wherein the top of solar thermal collector is the flow of cooled air chamber, and the bottom is the hot air flow chamber, and the outlet of hot air flow chamber is connected to the hothouse bottom by hot air duct, so that the hot-air after the heat exchange is sent in the hothouse.The hot and cold water pipe of solar thermal collector links to each other with storage tank respectively, utilizes solar energy also water in the heating water tank in heated air flow, so that behind the deposit heat energy, is used for the baking at night, perhaps is used for other.Described body of wall comprises base insulating layer, and middle heat-sink shell and outside lighting heat preserving cloche so that absorb solar energy to greatest extent, improve solar energy utilization ratio.Be provided with the multi units tube road in base insulating layer, wherein an end of one group of pipeline links to each other with external heat exchanger, and the other end links to each other with storage tank, so that utilize other heat energy to toast in the date of no sunlight.

The utility model compared with prior art has following advantage and good effect: owing to be provided with solar thermal collector, therefore, add hot water when can utilize solar energy to toast at heated air flow and to the article in the hothouse, thereby, perhaps provide hot water for other purposes for the baking at night provides heat energy.This programme body of wall is provided with large-area heat-sink shell and lighting heat preserving cover in addition, also have other auxiliary heat energy simultaneously, therefore, can make full use of solar energy and lay in its heat energy, improve heat utilization efficiency, make it to have thermal efficiency height, do not consume energy or few power consumption, multiple functional, broad-spectrum roasting plant, be fit to rural area baking grain, flue-cured tobacco, seed, medicinal material, timber and other agricultural byproducts, and can handle processing of dewatering such as thin dish, fruit.

Fig. 1 is the section structure schematic diagram of the utility model;

Fig. 2 is the Facad structure figure of the utility model.

Below in conjunction with accompanying drawing the utility model is described further, is not limited to this but hold within the utility model.

Among the figure, 1 is body of wall, assemble by cement prefab, the outer end face and the lateral surface of body of wall Chaoyang are provided with lighting heat preserving cloche 13, body of wall is provided with thermal isolation and heat storage layer 14, the extexine of this thermal isolation and heat storage layer is the heat-sink shell that scribbles solar energy heat absorbing coating 11,2 is hothouse, be located at the body of wall inboard, be used to place the article of various needs bakings, can be used as shower cabinet when not needing baked good uses, 3 is spray head for shower, link to each other with storage tank 5 by pipeline 4,6 is automatic water inlet valve, link to each other with storage tank, 7 is dehumidification tube, be located at the hothouse top, 8 is cold water pipe, 9 is solar thermal collector, be arranged at intervals at the hothouse top, after managing 91 1 ends and hot-water line 92 link to each other in the heat exchange on it, be connected to storage tank top again, after managing 91 other ends and cold water pipe 93 links to each other in the heat exchange, be connected to the storage tank bottom, so that realization thermal cycle, 10 is the hot air flow chamber, and its outlet is made as a plurality of, and links to each other with corresponding warm-air pipe 12 respectively, hothouse 2 bottoms all are located in the outlet 20 of this warm-air pipe, so that heat air delivery in hothouse, 15 is the flow of cooled air chamber, by the space on solar thermal collector 9 tops, and the space between lighting heat preserving cloche 13 and the thermal isolation and heat storage layer 14 constitutes, the air inlet 19 of this flow of cooled air chamber is located at lighting heat preserving cloche bottom, and 16 is the heating tube of external heat exchanger, and an end links to each other with external heat exchanger 18, the other end links to each other with storage tank 5,17 is the cold water pipe of external heat exchanger, and an end links to each other with external heat exchanger 18, and the other end links to each other with storage tank 5,18 is external heat exchanger, can be electrothermal furnace or boiler.The course of work of the present utility model is: when be sunshine, absorb solar energy by solar thermal collector 9, and heat the water in the pipe 91 in its heat exchange, simultaneously cold air 19 can obtain the part heating when entering in the flow of cooled air chamber 15 from entering the mouth, after obtaining step heating during again by the gap between the solar thermal collector, enter in the hot air flow chamber 10, enter hothouse 2 from the hothouse bottom through warm-air pipe 12, and after the article in it are toasted, discharge from moisture exhausting port 7 at last.To night can continue to toast with the hot water in the storage tank.Baking temperature can be regulated by the valve at air inlet 19 places.When all the time according to the time, toast by outer heat-exchanger 18.
