Example Embodiment

[0024] Example
[0025] See attached Figure 1-3 , An energy-saving and environmentally-friendly grain dryer, comprising a bracket 1, a supporting horizontal plate 2 is fixedly welded on the upper side of the bracket 1, and a motor base 3 is fixedly connected to the lower side of the supporting horizontal plate 2 by bolts, and the support The horizontal plate 2 is convenient to install and fix the motor base 3, the motor 4 is fixedly installed under the motor base 3, the output end of the motor 4 is connected with a reducer 5, and the output end of the reducer 5 is connected with a belt Disk 6, the lower side of the supporting horizontal plate 2 is fixedly installed with a shaft sleeve 9 through a vertical plate, and a drive shaft 8 is installed in the shaft sleeve 9 to drive between the drive shaft 8 and the belt pulley 6 through a belt 7 The upper part of the supporting horizontal plate 2 is fixedly welded with an outer cylinder body 12, and an inner cylinder body 13 is arranged inside the outer cylinder body 12. The upper end of the driving shaft 8 penetrates the lower end of the outer cylinder body 12 and drives The shaft 8 extends to the inside of the outer cylinder 12, a main shaft 10 is connected above the drive shaft 8, a spiral blade 11 is provided on the outside of the main shaft 10, and a hopper is fixedly installed on the upper side of the outer cylinder 12 22. The lower side of the outer cylinder 12 is provided with a discharge port 21, the side of the outer cylinder 12 is provided with an air inlet duct 20, and one side of the bracket 1 is provided with an air blowing mechanism 24. The air blowing mechanism 24 is flanged between the branch pipe 19 and the air inlet pipe 20.
[0026] Specifically, the blowing mechanism 24 includes a blower 16, the output end of the blower 16 is connected to a heating device 17 through a pipe 18, and a branch pipe 19 is connected to the heating device 17, and the heating device 17 is a hot air stove , The outer cylinder 12 and the inner cylinder 13 are fixedly connected by a connecting rod 25, the lower ends of the outer cylinder 12 and the inner cylinder 13 are connected together, and the lower ends of the outer cylinder 12 and the inner cylinder 13 A discharge hole 14 is opened at the connection, and honeycomb holes 15 are uniformly arranged on the inner cylinder body 13, the aperture of the honeycomb holes 15 is 0.5 mm, and a gap is provided between the outer cylinder body 12 and the inner cylinder body 13 In layer 26, the upper end of the outer cylinder 12 is fixedly installed with a bearing seat 23, the upper end of the main shaft 10 is installed in the bearing seat 23, and the end of the air inlet duct 20 close to the outer cylinder 12 is inclined downward.
[0027] A method for using an energy-saving and environment-friendly grain dryer. The specific steps of the method for using the energy-saving and environment-friendly grain dryer are as follows:
[0028] S1: Dryer detection, first check whether the valve of the discharge port 21 of the dryer is closed, and oil the shaft, and check whether the air blowing mechanism 24 is working normally;
[0029] S2: Close the valve of the discharge port 21, introduce grain from the upper end hopper 22 of the outer cylinder 12, and the grain enters the inner cylinder 13, and then start the motor 4 and the blowing mechanism 24;
[0030] S3: The motor 4 can drive the rotation of the drive shaft 8 through the belt 7, and the drive shaft 8 drives the rotation of the main shaft 10. The spiral blade 11 provided on the main shaft 10 will drive the grain inside the inner cylinder 13 to move upward, and the grain is moving upward During the process, due to gravity and the upper part of the inner cylinder 13 is in a sealed state, the grain will return to the bottom of the inner cylinder 13 from the gap between the spiral blade 11 and the inner cylinder 13;
[0031] S4: The blower 16 of the air blowing mechanism 24 blows air into the hot blast stove, and the hot blast stove heats the air, and then enters into the air inlet duct 20 through the branch duct 19, and the hot air of the inlet duct 20 is in the outer cylinder body 12 and the inner cylinder body The gap layer 26 between 13 circulates and enters the inner cylinder 13 from the honeycomb holes 15 to dry the grain with hot air.
[0032] When the present invention is used, the motor 4 can drive the rotation of the drive shaft 8 through the belt 7, and the drive shaft 8 drives the rotation of the main shaft 10. The spiral blade 11 provided on the main shaft 10 will drive the grain inside the inner cylinder 13 to move upward. During the upward movement, due to gravity and the upper part of the inner cylinder 13 is in a sealed state, the grain will return to the bottom of the inner cylinder 13 from the gap between the spiral blade 11 and the inner cylinder 13; the blower 16 of the air blowing mechanism 24 sends the hot air Air is blown into the furnace, and the hot blast stove heats the air, and then enters into the air inlet duct 20 through the branch pipe 19. The hot air from the inlet duct 20 circulates in the gap layer 26 between the outer cylinder 12 and the inner cylinder 13, from The honeycomb holes 15 enter the inner cylinder 13 to dry the grain with hot air.
