Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 5 shown, a biomass gasification drying device includes a tank body 1. A feeding port 2 is arranged on the front surface of the tank body 1. An exhaust port 3 is arranged at the bottom of the front surface of the tank body 1. A circular groove 4 is fixedly connected to the top wall of the tank body 1. A circular plate 5 is slidably connected inside the circular groove 4. A through port 6 is opened on the bottom wall of the circular groove 4. A cylinder 7 is slidably connected inside the through port 6. The bottom of the cylinder 7 is fixedly connected to the circular plate 5. A rotating rod 8 is arranged inside the cylinder 7. A spiral blade 9 is fixedly connected to the surface of the rotating rod 8. A motor bracket 10 is fixedly connected to the top of the tank body 1. A motor 11 is fixedly connected to the top wall of the motor bracket 10. The top end of the rotating rod 8 penetrates through the circular plate 5 and extends to the top of the tank body 1 and is fixedly connected to the output end of the motor 11. The top end of the rotating rod 8 is slidably connected to the circular plate 5. A discharge port 12 is opened on the bottom wall of the tank body 1. A discharge pipe 13 is fixedly connected to the bottom of the tank body 1. A valve 14 is arranged inside the discharge pipe 13. A communicating pipe 15 is communicated with the side surface of the cylinder 7. The output end of the communicating pipe 15 inclines downward. A heating layer 31 is arranged in the interlayer of the tank body 1.

[0022] Referring to Figure 1 , a main pulley 16 is sleeved on the surface of the top end of the rotating rod 8. A transmission rod 17 is rotatably connected to the top wall of the tank body 1. The top end of the transmission rod 17 extends to the top of the tank body 1 and is fixedly sleeved with a secondary pulley 18. A belt 19 is sleeved on the surfaces of the secondary pulley 18 and the main pulley 16. The main pulley 16 is in transmission connection with the secondary pulley 18 through the belt 19. The bottom end of the transmission rod 17 penetrates to the inside of the tank body 1 and is fixedly connected with a transmission gear 20. A toothed ring 21 is fixedly sleeved on the surface of the top end of the cylinder 7. The toothed ring 21 is located at the bottom of the circular groove 4. The toothed ring 21 is meshed with the transmission gear 20.

[0023] As a technical optimization solution of the present utility model, through the arrangement of the transmission gear 20 and the gear ring 21, while the rotating rod 8 and the spiral blade 9 convey the waste particles, the motor 11 drives the main pulley 16 at the top of the rotating rod 8 to rotate. The main pulley 16 drives the secondary pulley 18 and the transmission rod 17 to rotate through the belt 19. The rotation of the transmission rod 17 causes the transmission gear 20 to rotate. The transmission gear 20 drives the circular groove 4 to rotate by meshing with the gear ring 21, and the circular groove 4 further drives the connecting pipe 15 to rotate, avoiding the continuous contact of the waste particles output by the connecting pipe 15 with one place on the inner wall of the tank body 1, resulting in faster heat dissipation at this place on the inner wall and affecting the drying efficiency. It enables the connecting pipe 15 to rotate 360°, making the contact between the waste particles and the inner wall of the tank body 1 more uniform, and further improving the drying efficiency.

[0024] Reference Figure 1 and Figure 2 , an air inlet hole 22 is provided on the surface of the tank body 1. A hot air blower 23 is arranged on the right side at the top of the tank body 1. The output end of the hot air blower 23 is communicated with a hot air pipe 24, and the hot air pipe 24 is communicated with the air inlet hole 22.

[0025] As a technical optimization solution of the present utility model, through the arrangement of the hot air blower 23, the hot air blower 23 can be started to blow out hot air, accelerating the air flow, enabling the moisture inside the tank body 1 to be quickly discharged through the exhaust port 3, avoiding the influence of high moisture content on the drying process, and at the same time, the blown hot air avoids the rapid loss of heat inside the tank body 1, further improving the practicability of the device.

[0026] Reference Figures 2 to 4 , a moisture discharge port 25 is provided on the rear wall of the tank body 1. A moisture discharge pipe 26 is fixedly connected inside the moisture discharge port 25. A labyrinth channel 27 is arranged in the interlayer of the tank body 1. The moisture discharge pipe 26 penetrates through the heating layer 31 and extends into the interior of the labyrinth channel 27 and is communicated with it. The labyrinth channel 27 is located outside the heating layer 31. The exhaust port 3 penetrates into the interior of the labyrinth channel 27 and is communicated with it.

[0027] As a technical optimization solution of the present utility model, through the arrangement of the labyrinth channel 27, the moisture can be discharged into the interior of the labyrinth channel 27 through the moisture discharge port 25 and the moisture discharge pipe 26. The labyrinth channel 27 prolongs the residence time of the heat, and thus can keep the inner wall of the tank body 1 warm, avoiding the rapid loss of heat through the outer wall of the tank body 1.

[0028] Reference Figure 2 and Figure 3 , both sides of the surface of the cylinder 7 are fixedly connected with stirring rods 28. The number of the stirring rods 28 is several. The stirring rods 28 are vertically arranged in an array, and the two ends of the bottom stirring rod 28 incline inwards.

[0029] As a technical optimization solution of the present utility model, through the arrangement of the stirring rod 28, the waste particles discharged from the communicating pipe 15 can be stirred by the rotation of the stirring rod 28, increasing the gaps between the waste particles, thereby accelerating the rapid discharge of the evaporated moisture inside the waste particles, and further improving the drying efficiency of the device.

[0030] Reference Figure 3 and Figure 5 , the diameter of the through port 6 is smaller than the diameter of the circular plate 5, a rolling groove 29 is opened on the bottom wall of the circular groove 4, and a number of balls 30 are rotatably connected inside the rolling groove 29, and the balls 30 are rotatably connected to the bottom surface of the circular plate 5.

[0031] As a technical optimization solution of the present utility model, through the arrangement of the balls 30, the friction between the circular plate 5 and the circular groove 4 is greatly reduced, so that the circular plate 5 drives the cylinder 7 to rotate more smoothly and labor-savingly when rotating, making the device operate more smoothly.

[0032] The working principle and usage process of the present utility model: When in use, the user first puts the waste particles into the interior of the tank body 1 through the feeding port 2, and starts the heating layer 31 so that the heating wire inside heats the inner wall of the tank body 1. Then start the motor 11 to make the rotating rod 8 rotate, and the rotating rod 8 drives the spiral blade 9 to rotate to spirally convey the waste particles located at the center upward into the interior of the cylinder 7 and discharge them through the communicating pipe 15, so that the waste particles located at the center can fully contact the inner wall of the tank body 1. While the rotating rod 8 and the spiral blade 9 convey the waste particles, the motor 11 drives the main pulley 16 at the top of the rotating rod 8 to rotate, and the main pulley 16 drives the auxiliary pulley 18 and the transmission rod 17 to rotate through the belt 19. The transmission rod 17 rotates to make the transmission gear 20 rotate, and the transmission gear 20 drives the circular groove 4 to rotate by meshing with the gear ring 21. The circular groove 4 then drives the communicating pipe 15 to rotate, so that the communicating pipe 15 can rotate 360°, making the contact between the waste particles and the inner wall of the tank body 1 more uniform. At the same time, the cylinder 7 drives the stirring rod 28 to rotate to stir the waste particles, accelerating the rapid dissipation of the moisture inside the waste particles. The dissipated moisture can be discharged into the interior of the labyrinth channel 27 through the moisture discharge port 25 and the moisture discharge pipe 26, while insulating the tank body 1 and then discharged from the exhaust port 3. Subsequently, start the hot air blower 23 to blow hot air into the interior of the tank body 1, accelerating the air flow and the rapid discharge of moisture. After drying is completed, open the valve 14 to unload the waste particles, and at the same time reverse the motor 11 to drive the rotating rod 8 and the spiral blade 9 to rotate to discharge the waste particles inside the cylinder 7.
