Standby technical field.
Background technique
Current solar drying apparatus such as greenhouse type drier, heat collection type drier etc. all can only be in the shorter time
Using thermal energy brought by solar radiation, in solar thermal utilization, due to day-night change and weather, the shadow of seasonal factor
It rings.So that arid cycle is longer, product uneven heating, so that the dry mass of product is difficult to ensure.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of dry dress of the photovoltaic and photothermal coupled solar containing heat-storage medium
It sets, to solve above-mentioned problems of the prior art.
The technical scheme adopted by the invention is as follows: a kind of photovoltaic and photothermal coupled solar drying device containing heat-storage medium, packet
The herringbone top cover for including wall and being covered at the top of wall, herringbone top cover use Fei Nier lens and solar panel
Splicing production, two medial surface of wall are provided with the heat-storing device of opposite herringbone roof side, and heat-storing device includes mutually nested
Inner and outer tubes, heat-storage medium is filled between inner and outer tubes, and wall is provided with exhaust blower close to top and is arranged close to bottom
There are multiple air inlets.
Preferably, above-mentioned outer pipe surface is provided with heat absorbing coating.
Preferably, above-mentioned framework inside circumference and bottom are laid with thermal insulation thermal insulation board.
Preferably, the tilt angle of above-mentioned herringbone top cover is local latitude.
Beneficial effects of the present invention: compared with prior art, the present invention uses the structure of relative closure, when there are sun spokes
When penetrating, top Fei Nier lens collect more light from all directions and enter the internally dry material of drying device, while drying device
The heat-storing device that inside is coated with selective heat absorbing coating carries out heat accumulation, and selective heat absorbing coating is obviously improved Heat-collecting effect,
The heat of dried material when heat-storing device provides no solar radiation, the solar panel at top convert light energy into electric energy
It is then converted to chemical energy and is stored in battery finally provide power for blower, be had followed using solar power generation environmentally protective
Theory, blower forced-convection heat transfer dramatically increase heat transfer effect, greatly improve the efficiency of solar energy utilization and daily drying
Time, product are heated evenly.

In figure, 1- wall, 2- phenanthrene Neil lens, 3- solar panel, 4- exhaust blower, 5- inner tube, 6- outer tube, 7- air inlet
Mouthful, 8- sealing ring.
Specific embodiment
With reference to the accompanying drawing and the present invention is described further in specific embodiment.
Embodiment 1: as Figure 1-Figure 2, a kind of photovoltaic and photothermal coupled solar drying device containing heat-storage medium, including
Wall 1 and the herringbone top cover for being covered in 1 top of wall, herringbone top cover use Fei Nier lens 2 and solar battery
The splicing production of plate 3,1 liang of medial surface of wall are provided with the heat-storing device of opposite herringbone roof side, and heat-storing device includes mutually embedding
The inner tube 5 and outer tube 6 of set, are filled with heat-storage medium between inner tube 5 and outer tube 6, wall 1 is provided with exhaust blower 4 close to top and leans on
Nearly bottom is provided with multiple air inlets 7, the sealing of 6 one end of outer tube, and the other end is sealed using dismountable sealing ring 8, facilitates progress
The injection of heat-storage medium, solar panel are connected to battery, and battery is connected to exhaust blower, reduce making for additional power supply
With reducing cost.
Preferably, above-mentioned 6 surface of outer tube is provided with heat absorbing coating, improves heat absorption efficiency, and heat accumulation effect is more preferable.
Preferably, above-mentioned 1 inside circumference of framework and bottom are laid with thermal insulation thermal insulation board, avoid heat loss.
Preferably, the tilt angle of above-mentioned herringbone top cover is local latitude, can absorb solar energy to greatest extent.
Working principle is: material being put into drying device together with material frame, drying box is shut, Fei Nier lens is set
In sun light direct beam position, when there are solar radiation, top Fei Nier lens collect more light from all directions and enter drying
Inside device, drying device Inside Air Temperature is gradually increasing, the heat of hot-air under the action of blower with surface of material into
Row forced-convection heat transfer, the moisture in material is heated to be vapor and is discharged outside drying device by blower, while drying device
The heat-storing device that inside is coated with coating for selective absorption carries out heat accumulation, and the solar panel at top converts light energy into electric energy again
It is converted into chemical energy and is stored in battery and finally provide power for blower.When lacking solar radiation, under the action of blower
Heat-storing device and drying device inner air carry out forced-convection heat transfer, and the air being heated and surface of material carry out forced convertion
It exchanges heat, the moisture in material is heated to be vapor and is discharged outside drying device by blower.In order to improve the heat preservation of drying device
Heat insulation reduces heat loss, is laid with thermal insulation thermal insulation board in 1 inside circumference of framework and bottom.In order to send out solar panels
Electricity is as big as possible, and taking local latitude is solar panels mounting inclination angle.
