Abstract

The invention discloses a solar dryer with a drying agent to absorb moisture. The dryer consists of a heat collector, a fan, a pipeline, a drying cabin and a moisture absorbing box, wherein a heat collection plate of the heat collector is a porous heat collection plate; a drying cabin porous sieve is placed at an angle of about 20 degrees; a plurality of drying bags are hung in the moisture absorbing box; air circularly flows in the heat collector, the drying cabin and the moisture absorbing box; and thus, the heat loss caused by waste gas emission is reduced. The drying temperature is about 30-50 DEG C; and the quality of a dried product is guaranteed.

Description

The solar dryer of subsidiary drier moisture absorption
One, technical field
The present invention relates to solar energy utilization technique and crops dry technology, refer in particular to a kind of solar dryer that hot air circulate is utilized that porous flat plate solar energy air heat collector and dryness storehouse and moisture absorption chamber are combined.
Two, background technology
In the dry field of crops, mostly common drying source is fire coal or fuel Heating now, and hot air temperature causes product quality to descend about 200 ℃ easily.
At present existing a plurality of patents about solar dryer are crossed high reason but reach cost owing to solar energy utilization ratio is low, still remain to be promoted.Below list several existing related patent U.S. Patent No.:
(application number: 200620057287.2) propose a kind of solar dryer, its thermal-arrest partly is a collection flat heat to patent " quick high-temp solar dryer ", and air is crossed heat absorption from the channel flow between flat board and the transparent cover plate, gets into drying device and carries out drying.
(application number: 201010600814.0) propose a kind of solar dryer, its thermal-arrest partly is a heat collecting glass tube to patent " solar dryer ", and through the two-period form fin heat pipe heat is delivered to drying box.Waste heat reclaims through the Waste Heat Recovery heat exchanger.
Three, summary of the invention
The present invention proposes a kind of solar dryer of subsidiary drier moisture absorption.This drier is made up of solar energy air heat collector, ventilation shaft, blower fan, dryness storehouse and moisture absorption case.Wherein solar energy air heat collector is the porous flat plate solar energy air heat collector.Concrete structure comprises: air inlet, air outlet, insulation shell, transparent cover plate and porous thermal-arrest plate.Porous thermal-arrest plate is a metallic plate, is coated with coating for selective absorption on the plate, and is drilled with equally distributed aperture at interval.Thermal-arrest panel edges and insulation shell combine closely and the cavity that insulation shell and transparent cover plate surround is divided into before and after two parts.Air inlet and ante-chamber sports association are logical, air outlet and rear chamber UNICOM.Blower fan is during from the heat collector exhaust, and air cavity in the past passes the heat absorption of porous plate aperture, gets into rear chamber.The dryness storehouse structure comprises: air inlet, air outlet, outlet, all press chamber, housing and porous sieve etc.The porous sieve is horizontal by 20 ° of left and right sides angles, and the cereal behind the convenient and dry gushes dryness storehouse, cereal upper surface after guaranteeing simultaneously to stack and the parallel not landing of porous sieve.The moisture absorption case is made up of housing, air inlet, air outlet, slide rail, dry bag etc., and dry bag is selected the material of good permeability for use, and the physics hygroscopic agent that inner filling can reuse is like clay hygroscopic agent etc.The shape that dry bag is made should make things convenient for air to contact with drier, and the cross section is as shown in Figure 3.The air that in heat collector, heats up gets into dryness storehouse and passes the dry thing of placing on porous sieve and the porous sieve under fan action, moisture is taken away, and becomes humid air.After humid air gets into the moisture absorption case, dehumidify, and flow back into the heat collector repeated use through pipeline through the dry bag surface.Use through hot air circulate, reduced thermal loss.
Four, description of drawings
Below in conjunction with accompanying drawing, the present invention is described further.
Fig. 1 is this schematic representation of apparatus.
Fig. 2 is this device heat collector A-A cutaway view.
Fig. 3 is a moisture absorption case profile.
Fig. 4 is a moisture absorption case partial enlarged drawing.
The position of marking is respectively among the figure: 1, porous flat plate solar energy air heat collector; 2, blower fan; 3, all press the chamber; 4, porous sieve; 5, dry thing; 6, dryness storehouse outlet; 7, moisture absorption case; 8, transparent cover plate; 9, insulation shell; 10, porous thermal-arrest plate; 11, heat collector air outlet; 12, preceding cavity; 13, rear chamber; 14, dry bag; 15, clamp; 16, slide rail.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described further.
Daytime, porous thermal-arrest plate 10 was converted into heat energy with luminous energy, after blower fan 2 is opened, air is sucked cavity before the heat collector from the heat collector air inlet, and pass the aperture on the porous thermal-arrest plate 10, got into rear chamber.Hot-air through after the aperture heat absorption gets into dryness storehouse, through all pressing chamber 3, passes porous sieve 4, passes dry thing gap then, moisture is taken away, and flowed out from the dryness storehouse air outlet.Dryness storehouse inner drying thing thickness is about 0.5 meter.The also oriented dryness storehouse of dryness storehouse outlet 6 adds the effect of dry thing.Hot-air flows into moisture absorption case 7 from dryness storehouse, passes the dry bag 14 of suspension.Filled drier in the dry bag 14, airborne moisture has been removed.Absorb heat in through dried air, realize the heat recycle through pipeline entering solar energy air heat collector.Seal with clamp 15 dry bag 14 upper ends, and be placed in the slide rail 16 on moisture absorption case 7 tops, the convenient taking-up.Drier is wanted the high temperature dehumidifying after using a period of time.
