The feeding port 6 can be used to add materials to the shell 1, and the processed materials can be discharged to the outside through the discharge shell 7. A belt conveyor component 2 is installed inside the shell 1, and the belt conveyor component 2 can transport materials inside the shell 1. A drying component 3 and a heat circulation component 4 are respectively provided on the top of the shell 1. The drying component 3 can generate heat to dry the materials inside the shell 1. The heat circulation component 4 can utilize the heat inside the shell 1 to reduce the energy consumption of the equipment. The drying component 3 includes a hot air blower 301 installed on the top of the shell 1, and the heat circulation component 4 is an exhaust fan 401 installed through the top of the shell 1. The output end of the exhaust fan 401 is connected to a group of conveying pipes 402, and each conveying pipe 402 is connected to the hot air blower 301 at one end away from the exhaust fan 401.

[0021] Among them, a feeding device 5 is placed on the right side of the shell 1, and the output end of the feeding device 5 extends to the top of the feed port 6. The provided feeding device 5 can feed the material into the inside of the feed port 6.

[0022] Among them, the belt conveyor component 2 includes two groups of vertical plates 202 connected to the inside of the outer shell 1, and the inner wall of the discharge shell 7 and the side surface of the two groups of vertical plates 202 close to each other are rotated together to connect a group of conveyor belts 203. The conveyor belts 203 can be installed through the vertical plates 202. The positions of the arranged conveyor belts 203 are staggered and overlapped with each other, and are of different lengths. The output end of the conveyor belt 203 at the bottom extends to the discharge shell 7 on the left side of the outer shell 1 to deliver the material.

[0023] Among them, the output end of each conveyor belt 203 passes through the vertical plate 202 and is connected to a gear 204. A group of gears 204 are meshed with each other. By utilizing the meshing action of the gears 204, two adjacent conveyor belts 203 can rotate in opposite directions to transport materials.

[0024] Among them, the outer surface of one of the gears 204 is connected to the driving shaft 205, and the outer surface of the shell 1 is installed with a driving motor 201. The output end of the driving motor 201 passes through the shell 1 and is connected to the driving shaft 205. The driving motor 201 provides power to drive the driving shaft 205 and one of the gears 204 to rotate. Through the mutual engagement of the gears 204, the entire conveyor belt 203 can be driven to run.

[0025] Among them, the drying component 3 also includes two curved heat supply pipes 302 installed inside the shell 1.

After starting the device, the loading device 5 can be used to transport materials, and the materials can pass through the feed port 6 and fall onto the conveyor belt 203 inside the shell 1. The conveyor belt 203 can be used to transport these materials. During the transportation process, the installed hot air blower 301 can generate heat and evenly send the heat into the interior of the shell 1 through the curved heat supply pipe 302. The heat can be used to quickly dry the material above the conveyor belt 203. At the same time, the exhaust fan 401 can also be used to extract the moisture and a small amount of hot air generated by the drying material. The hot air containing moisture can be sent into the hot air blower 301 through the conveying pipe 402 to evaporate the moisture, and the hot air is heated again and sent into the interior of the shell 1 through the curved heat supply pipe 302, thereby recycling the heat to reduce energy consumption. The dried material can be transported outward through the discharge shell 7 for processing by the staff.
