the grain enters the material guide hopper 814 through the feed hopper 810 and enters the material tank 803 through the material guide hopper 814, the scattering motor 812 and the gear pair 813 are matched to drive the two rotating rods 811 to rotate, the grain entering the feed hopper 810 is scattered through the plurality of support rods, the rotating motor 806 drives the rotating gear 807 and the toothed ring 805 to rotate, further drives the rotating ring 802 to rotate, the material entering the material tank 803 from the scattering assembly is discharged through the material discharging pipe 804, the material discharging pipe 804 rotates along with the rotating ring 802 at a constant speed, so that the material is scattered more uniformly on the helical blade 6, hot air entering the hot air cylinder 3 from the air inlet pipe 4 is blown out through the air outlet 5, the grain entering the silo 2 is primarily heated at the upper end of the silo 2, the helical blade 6 vibrates under the driving of the first vibrating motor 11, the grain slides to the middle section of the silo 2 through the helical blade 6, at the moment, hot air blown out from the air outlet 5 directly passes through grains and is blown out through the air outlet 7 to take away moisture on the grains, the grains continuously descend along the helical blades 6, hot air flow blown out from the air outlet 5 is dried and then continuously moves upwards and is discharged through the air outlet 7, the moisture content of the grains at the bottom is low, so that the steam content of the rising hot air flow is low, the grain does not attach to the grains at the upper layer due to the upward movement, the drying effect of the grains at the upper layer can be enhanced, the steam generated by the grains is timely discharged, secondary wetting of the grains can not be caused, the hot air supply requirement is reduced, the energy saving and emission reduction effects are further realized, the dried grains fall at the bottom of the silo 2, the discharge motor 904 drives the auger 903 to rotate, the grains at the lower end of the silo 2 are lifted upwards through the discharge pipe 901, and meanwhile, the filter cartridge 1001 can filter impurities such as dust in the grains, prevent that the dust from wafting, contaminated air, cartridge filter 1001 is outstanding to silo 2 inside, can not fill the jam by cereal, changes easily moreover, hangs guide duct 1006 in the outside of silo 2 through fastener 1007 and limiting plate 1005 for the gas of combustion gas upwards removes in the cartridge filter 1001, prevents that steam from scalding the staff, increases the security of device.
In conclusion, water vapor generated by the grains is discharged in time through the hot air cylinder 3, the spiral blades 6, the air outlet 7 and the air outlet 5, so that secondary wetting of the grains is avoided, the hot air supply requirement is reduced, and the effects of energy conservation and emission reduction are further realized;
the dispersibility of the grains is improved through the feeding mechanism 8, the drying effect is improved, and the grains are kept warm when being discharged through the discharging mechanism 9, so that the follow-up self-flowing drying is facilitated;
through filtering mechanism 10 filtering and direction exhaust waste gas, prevent that the dust from wafting and the staff is scalded to waste gas, increase the security of equipment.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
