Abstract
The invention discloses a coil tumbling solar dryer with auxiliary heating, which comprises a solar heat collector, a fan, pipelines, a tumbling drying bin, an air heating furnace and a motor. A coil is welded on the back of a heat collecting plate of the heat collector, rollers are arranged on a holder of the drying bin, and the drying bin is connected with the motor through a gear structure and can roll under drive of the motor. Teeth are uniformly and circumferentially distributed inside the drying bin and can drive the dried articles to tumble, and the air heating furnace serving as an auxiliary heat source can guarantee all-weather operation of the dryer. The drying temperature of the solar dryer is about 30-50 DEG C, so that the quality of dried products is guaranteed.
Description
One, technical field
The present invention relates to solar energy utilization technique and crops dry technology, refer in particular to and a kind of coil pipe type solar energy air heat collector, air-heating furnace and rolling type dryness storehouse are combined and with the solar dryer of motor drives dryness storehouse rotation.
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 assistant heating coiled pipe rolling type solar dryer.This drier is made up of coil pipe type solar energy air heat collector, ventilation shaft, blower fan, rolling type dryness storehouse, air-heating furnace and motor.Wherein coil pipe type solar energy air heat collector concrete structure comprises: air inlet, air outlet, insulation shell, transparent cover plate, thermal-arrest plate and snake bend.The snake bend upper end is an air inlet, and the lower end is an air outlet.The thermal-arrest plate is a metallic plate, and the one side that faces south on the plate is coated with coating for selective absorption, and another side and snake bend weld together.Heating furnace is the iron plate welding production, and structure comprises air inlet, gas outlet, combustion chamber, heating clamber.Air inlet is the little rectangular aperture that uniform ring distributes around the bottom, can add forced ventilation.The heating clamber inner space is taper, and separates with iron-clad between the combustion chamber.When illumination was sufficient, blower fan was from the heat collector exhaust, and air gets into snake bend from air inlet, flows through behind the whole snake bend, goes out from air outlet.When illumination was not enough, the channel switch of air-heating furnace was opened on the ventilation shaft, and air-heating furnace is lighted, and blower fan extracts hot-air from air-heating furnace.The rolling type dryness storehouse is connected through gear structure with motor, is rolled by the motor drives dryness storehouse.Dryness storehouse is placed on the carriage, roller is housed on the carriage dryness storehouse can freely be rotated.The rear and front end of dryness storehouse has air inlet and air outlet, and is coated with fine mesh screen, prevents that dry gas stream from taking dry thing out of dryness storehouse.Be designed with the tooth of 6 even circle distribution on the dryness storehouse inwall, when dryness storehouse rolls, can drive dry thing and in the storehouse, roll, increase contacting of dry thing and hot-air, improve rate of drying.

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 1 as main thermal source, with air-heating furnace 2 as auxiliary thermal source.Valve is housed respectively on the ventilation shaft of heat collector and heating furnace.When illumination was sufficient, blower fan 3 started, and extracted hot-air from coil pipe type solar energy air heat collector 1 and sent into dry goods the rolling type dryness storehouse 4.Outside air gets into snake bend 11 from the air inlet 7 of coil pipe type solar energy air heat collector 1 upper end, in snake bend 11, after the heat absorption, gets into blower fan 3 from heat collector air outlet 8 through ventilation shaft 2.Rolling type dryness storehouse 4 rolls under the drive of motor 6, makes inner dry thing also roll thereupon.Hot-air gets into dryness storehouses through blower fan 3 effect from dryness storehouse air inlet 13, steam is blown out from dryness storehouse air outlet 14 after passing the material that rolls.When illumination is inadequate, the valve open of heating furnace 2 ventilation shafts, heating furnace is lighted, and blower fan 3 extracts hot-air from heating furnace heating clamber 21 and sends into dryness storehouse.
