Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described.
With reference to Fig. 1-2, a kind of grain heat-drying internal-circulation type drying machine, including drying device 1, dehydrating unit 2 and heatingDevice 3, drying device 1 is as the main body place of grain drying, and dehydrating unit 2 is for removing the moisture content in humid air, side by sideGoing out dry air, the dry air that dehydrating unit 2 is discharged by heater 3 heats up, being dried for grain.
Drying device 1 is arranged on base 5 by fixed support 4, and the side of drying device 1 is provided with hoisting mechanism 6, and dryThe opposite side of dry device 1 is provided with discharge pipe 7, and discharge pipe 7 connects the second humidity detector 21, the second Humidity DetectionDevice 21 is electrically connected with the controller, second humidity detector 21 water content after detecting grain drying, hoisting mechanism 6Bottom connects charging aperture 8, and the top connection of hoisting mechanism 6 has uniform device 9, the discharging opening of uniform device 9 and drying device 1Internal connection, grain is entered by charging aperture 8, and boosted mechanism 6 is promoted in uniform device 9, and the inside of drying device 1 is provided with multilamellarHorizontally disposed conveying mechanism, the time dry in drying device 1 to increase grain by arranging multilamellar conveying mechanism, improvesDrying effect, conveying mechanism by driving motor 10, roll shaft 11 and conveyer belt 12 to form, roll shaft 11 be fixedly connected on drying deviceOn the internal chamber wall of 1, conveyer belt 12 is netted conveyer belt, to improve the gas effect of vertical circulation, uniform device in drying device 1The discharging opening of 9 is arranged on the top of the conveying mechanism of the superiors in drying device 1, uniform device 9 by moist grain all and dissipateCloth is on conveyer belt 12, and in drying device 1, the discharge end of undermost conveying mechanism is positioned at the inside of discharge pipe 7, is dried dressPut 1 upper end to connect with collector-shoe gear 13, and collector-shoe gear 13 is connected with the air inlet of dehydrating unit 2 by admission line 14.
