Drawings
Fig. 1 is a schematic view of the cross-sectional structure of the present invention.
Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in the attached figure 1, the utility model discloses a grain dryer, which comprises a shell 2, a moisture discharge port 6 is arranged at the top of the shell 2, a feed port 7 is arranged on the side wall of the shell 2, the feeding hole 7 is connected with a negative pressure fan 8, the negative pressure fan 8 is connected with a feeding pipe 9, an upper hot air port 15 is arranged at the top of the shell 2, an upper hot air pipe is connected with the upper hot air port 15, a drying cavity is arranged at the bottom in the shell 2 and comprises an inner cavity 13 and an outer cavity 14, an interlayer space 12 is arranged between the inner cavity 13 and the outer cavity 14, an air outlet micropore 11 communicated with the inner space of the shell 2 is arranged on the side wall of the outer cavity 14, an air inlet micropore 10 communicated with the interlayer space 12 is arranged on the side wall of the inner cavity 13, a lower hot air pipe 16 communicated with the inner cavity of the drying cavity is arranged at the bottom of the shell 2, the outer cavity side wall of the drying cavity is arranged to be in. The micropore of giving vent to anger and the micropore aperture of ventilating all are less than cereal granule's size usually to make cereal granule be difficult for dropping the drying chamber in giving vent to anger the micropore, ensure hot-blast discharge in can following the drying chamber again simultaneously, realize the bottom and be heated, the heating of hot-blast mouthful in the cooperation is heated more evenly. Moisture generated by the heating process may be discharged from the moisture discharge port.
The region of the interlayer space 12 of the bottom surface of the shell 2 corresponding to the drying chamber is provided with a cleaning port 14, a cleaning valve is installed on the cleaning port, and grain particles or water drops and impurities falling into the interlayer space in the drying chamber can be discharged through the cleaning port.
