[0019] The drying processing structure includes: four electric rollers 2, two rotating mounting rings 3, a drying box 4, two air inlets 5, a material door 6, a material box 7 and two air inlet components;

[0020] Four electric rollers 2 are respectively installed at the four corners of the upper end of the base plate 1, two rotating mounting rings 3 are respectively located at the upper ends of the four electric rollers 2, a drying box 4 is fixedly installed in the two rotating mounting rings 3, two air inlets 5 are respectively opened at the walls on both sides of the drying box 4, a material door 6 is installed at the side walls of the drying box 4 by bolts, a material box 7 is placed at the center of the upper end of the base plate 1, and two air inlet assemblies are respectively installed on both sides of the upper end of the base plate 1, and are movably mounted on both sides of the drying box 4.

[0021] When drying and cooling the positive electrode material, the staff first opens the material door 6 on one side of the drying box 4, injects the positive electrode material into the drying box 4 and closes the material door 6, and then the four electric rollers 2 are synchronously rotated to drive the two rotating mounting rings 3 and the drying box 4 to rotate at a uniform speed, so that the material is repeatedly turned over in the drying box 4, and then the air inlet components on both sides of the upper end of the bottom plate 1 are driven to work, and the external cold air is transported to both sides of the drying box 4 through the air inlet 5, and the material in the drying box 4 is dried and cooled. The use of two-way air intake to dry and cool the material can effectively increase the overall drying and cooling effect of the material, and after the drying and cooling is completed, the material door 6 is opened to achieve rapid unloading of the material.

[0022] In the specific implementation process, the two air inlet components include: an air inlet cover 8, an annular slide rail 9, an annular slider 10, a fan 11 and an air supply pipe 12;

[0024] When the material is dried and cooled, the staff drives the fan 11 in the air inlet hood 8 to deliver air to the drying box 4 through the air supply pipe 12 and the air inlet 5. During the rotation of the drying box 4, the annular slide rail 9 located in the upper end of the drying box 4 rotates on the upper end of the annular slide block 10 to ensure the rotation effect of the drying box 4 and reduce the air leakage at the connection position of the air inlet hood 8 and the drying box 4.

[0025] In the specific implementation process, the middle section of the drying box 4 is a filter structure, which can realize the exhaust of air in the drying box 4.

[0026] In the specific implementation process, an air inlet filter 13 is embedded in the air inlet 5 to prevent foreign matter from entering the drying box 4 and affecting the materials.
