Abstract
The invention discloses a coil pipe integral type solar drier, which comprises a solar heat collector, a blower, a ventilating pipeline and a drying chamber. Heat collection plates of the heat collector are metal plates, the sunny sides of the metal plates are coated with selective absorption coatings, and snake bends are welded on the back sides of the metal plates, and a perforated sieve of the drying chamber is placed at an inclination angle of 20 degrees. The drying temperature of the system is around 30-50 DEG C, so that the quality of dried products is ensured. In addition, the air heat collector and the drying chamber constitute a whole with a compact structure, and the coil pipe integral type solar drier reduces heat loss and is suitable for crop drying quantity demanded by a single rural family.
Description
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 coil pipe type solar energy air heat collector and dryness storehouse is combined into an integral body.
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 coiled pipe monoblock type solar dryer.This drier is made up of solar energy air heat collector, ventilation shaft, blower fan and dryness storehouse.Wherein solar energy air heat collector is the coil pipe type solar energy air heat collector.Concrete structure comprises: air inlet, absorber plate, air outlet, snake bend, insulation shell and transparent cover plate.Air inlet is on heat collector top, and air outlet is in the heat collector bottom, and wherein absorber plate is the metal sheet that a sunny slope is coated with coating for selective absorption.The absorber plate back side is welded with snake bend, and the snake bend material is selected the good material of thermal conductivity for use, makes heat be delivered to snake bend from metallic plate rapidly.Blower fan is during from the heat collector exhaust, and air gets into snake bend from air inlet, flows out from air outlet behind the snake bend of flowing through.The dryness storehouse structure comprises: air inlet, air outlet, discharging opening, 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.Be provided with valve on the pipeline in solar energy air heat collector and air-heating furnace and being connected of blower fan, with the inflow direction of control hot-air.The housing of dryness storehouse surrounds a whole cavity with solar energy air heat collector; Drier is inner; Surround the space of dryness storehouse by coil pipe type solar thermal collector insulation shell, metallic plate and dryness storehouse housing, metallic plate all presses the chamber to separate blower fan and dryness storehouse.
Four, description of drawings
Below in conjunction with accompanying drawing, the present invention is described further.
Fig. 1 is the overall schematic of this device.
Fig. 2 is that the B of heat collector is to view.
Fig. 3 is a heat collector A-A cutaway view.
The position of marking is respectively among the figure: 1, heat collector air inlet; 2, heat collector air outlet; 3, transparent cover plate; 4, absorber plate: 5, snake bend: 6, heat collector insulation shell; 7, coil pipe type solar energy air heat collector; 8, ventilation shaft; 9, blower fan; 10, dryness storehouse air inlet; 11, all press the chamber; 12, porous sieve; 13, dryness storehouse outlet; 14, dry thing; 15, dryness storehouse air outlet.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described further.
This device with coil pipe type solar energy air heat collector 7 as thermal source.After blower fan 9 starts hot-air is extracted and sends into dry goods the dryness storehouse from coiled pipe solar energy air heat collector 7.Outside air gets into snake pipe 5 from coiled pipe solar energy air heat collector 7 top air inlets 1, and process and snake bend 5 abundant heat exchange get into blower fans 9 from heat collector outlet 2 through ventilation shaft 8 at last.Hot-air acts on all pressures chamber 11 that is introduced into dryness storehouse through blower fan 9, passes porous sieve 12 and dry thing 14 then, and moisture is discharged from dryness storehouse air outlet 15.Whole drier has reduced the length of gas pipeline, has reduced thermal loss.
