A driving structure 3 is provided inside the drying box 1, and a bearing structure 4 is fixedly connected to the outside of the driving structure 3. The driving structure 3 and the bearing structure 4 are used in conjunction with each other so that the solid electrolyte placed in the bearing structure 4 can rotate at a uniform speed in the drying box 1. The drying structure 5 is fixedly connected to the box walls on both sides of the drying box 1. The drying structure 5 generates heat to dry the solid electrolyte. A cooling structure 6 is fixedly connected to the rear end wall of the drying box 1. After the solid electrolyte is dried, it is cooled by the cooling structure 6 to avoid scalding the staff during the solid electrolyte removal process. A gas filtering structure 7 is provided at the bottom of the drying box 1. The gas generated during the cooling process is filtered and discharged to the outside of the drying box 1. A sealing door 8 is provided in front of the drying box 1. The sealing door 8 is used to seal the drying box during operation. An observation window 9 is provided in the sealing door 8. The observation window 9 can be used to observe the state of the solid electrolyte during the drying process.

[0022] The driving structure 3 includes a retarding motor 301, which is fixedly connected to the middle position of the bottom of the drying box 1. The top output end of the retarding motor 301 is fixedly connected to a rotating shaft 302. The retarding motor 301 rotates slowly to drive the rotating shaft 302 to rotate slowly. The top of the rotating shaft 302 is rotatably connected to the top of the drying box 1. A plurality of connecting rods 303 are longitudinally arranged around the outer periphery of the rotating shaft 302. The rotating shaft 302 drives the bearing structure 4 connected to the connecting rods 303 to rotate while rotating.

[0023] The bearing structure 4 includes a placement box 401, which is fixedly connected to the end of the connecting rod 303 away from the rotating shaft 302. A storage drawer 402 is slidably connected in the placement box 401. The top of the discharge drawer 402 is an open structure for placing solid electrolytes. A handle 403 is fixedly connected to the end of the storage drawer 402 away from the connecting rod 303. The handle 403 can be used to easily pull the storage drawer 402 out of the placement box. A heat insulation layer is fixedly connected to the surface of the handle 403. The handle 403 and the heat insulation layer are used together to avoid the residual heat of the handle 403 after cooling down, which may cause discomfort to the staff when taking it out.

[0024] The drying structure 5 includes a fixed column 501, which is fixedly connected to the box walls on both sides of the drying box 1, and the fixed column 501 is located between two upper and lower adjacent placement boxes 401.

A plurality of heating tubes 503 are arranged inside the installation box 502. The heating tubes 503 can be used in conjunction with the installation box 502 to heat and dry the solid electrolyte in the storage drawer 402, and the driving structure 3 drives the bearing structure 4 to rotate at a constant speed, so that the solid electrolyte can be dried more evenly.

[0025] The cooling structure 6 includes a refrigeration box 601, which is fixedly connected to the top of the drying box 1. A connecting pipe 602 is fixedly connected to the rear end of the refrigeration box 601. A cooling pipe head 603 is fixedly connected to the connecting pipe 602 near the side of the drying box 1. The refrigeration box 601 is cooled, and cold air is fed into the drying box 1 through the connecting pipe 602 and the cooling pipe head 603, thereby cooling the inside of the drying box 1. The cooling pipe head 603 is located between the upper and lower adjacent placement boxes 401. By arranging a plurality of cooling pipe heads 403, the solid electrolyte in each storage drawer 402 can be cooled, so that the cooling is more thorough.

[0026] The gas filtering structure 7 includes an air vent 701, which is provided at the bottom of the drying box 1 and is located on both sides of the retarder motor 301. A gas filtering device 702 is fixedly connected to the bottom of the drying box 1. The gas generated after the solid electrolyte is cooled enters the gas filtering device 702 through the air vent 701. An outlet pipe 703 is fixedly connected to one side of the gas filtering device 702. The gas filtering device 702 filters the cooling gas and discharges it through the outlet pipe 703 to avoid the direct exhaust of gas affecting the air environment.
