[0021] A second drive motor 12 is fixedly mounted on the outer side of the box body 1 through a bracket, the motor shaft of the second drive motor 12 is fixed to the rotating box 4, and the other end of the rotating box 4 is rotatably connected to the inner wall of the box body 1 through a bearing;

[0022] The box body slide groove 41 is located on the outer surface of the rotating box 4, the sliding box cover 42 is slidably installed at the box body slide groove 41, the box cover fixing bolt 43 is located on the outer surface of the box body 1, and the surface of the sliding box cover 42 is provided with bolt holes corresponding to the box cover fixing bolt 43;

[0023] The inner bottom surface of the box body 1 is provided with an inclined bottom plate 13, the bottom of the inclined surface of the inclined bottom plate 13 is arranged toward the box door 2, and a groove 14 along the width of the box body 1 is opened at the edge of the inclined bottom plate 13 where the inclined surface is low, and a water-absorbing sponge 15 is embedded in the groove 14.

[0024] The first drive motor 6 drives the sliding frame 9 to slide laterally on the transverse slide rail 5 through the screw 7 under the action of the screw nut slider 8, that is, under the screw nut principle, the sliding frame 9 slides laterally along the transverse slide rail 5, so that the air outlet 10 moves horizontally left and right in the box body 1 to blow out hot air.

[0025] The second drive motor 12 drives the rotating box 4 to flip in the space of the box body 1. The sliding frame 9 is located inside the box body 1 and on the top of the rotating box 4. During the horizontal movement of the sliding frame 9, the air outlet 10 blows hot air evenly to the flipping rotating box 4 to dry the lithium batteries in the rotating box 4.

[0026] The rotating box 4 is a steel mesh box, the aperture size of the mesh is similar to that of the gauze, and is used to allow the water in the lithium battery to seep from the rotating box 4 to the inclined bottom plate 13 and then fall into the groove 14 to be absorbed by the absorbent sponge 15.

[0027] Working principle:

[0028] In this scheme, the lithium battery to be dried is placed in the rotating box 4 after opening the sliding box cover 42, and the sliding box cover 42 is closed, and the box cover fixing bolts 43 are passed through the bolt holes on the sliding box cover 42 to complete the closing of the rotating box 4. After the box door 2 is closed, the hot air blower 3 is connected to an external power supply to work, and the air outside the back of the box body 1 is sucked in and heated by the electric heating wire of the hot air blower 3, and the hot air is guided to the multiple air outlets 10 at the bottom of the sliding frame 9 through the duct 11, so as to dry the lithium batteries in the rotating box 4 inside the box body 1 with hot air;

[0029] The first drive motor 6 works to drive the screw rod 7 to rotate at the top of the box body 1, so that the screw nut slider 8 moves horizontally on the screw rod 7. The first drive motor 6 is a forward and reverse motor, which is convenient for the left and right horizontal movement of the screw nut slider 8 on the screw rod 7. The screw nut slider 8 drives the sliding frame 9 to move horizontally at the horizontal slide rail 5, so that multiple air outlets 10 move horizontally in the box body 1. At the same time, the second drive motor 12 works to drive the entire rotating box 4 to flip inside the box body 1 through the motor shaft. A height difference is reserved between the rotating box 4 and the multiple air outlets 10 on the bottom of the sliding frame 9 for the rotating box 4 to flip.

[0030] The lithium battery is in a continuous tumbling motion in the rotating box 4, and is dried by the hot air blown out by the left and right lateral movement. The excess water will fall from the rotating box 4 through the mesh to the inclined bottom plate 13, and flow to the groove 14, and be absorbed by the water-absorbing sponge 15 embedded in the groove 14. After the lithium battery in the rotating box 4 is dried, the work of each electrical structure is stopped, and the box door 2 is opened, the box cover fixing bolts 43 are removed, and the sliding box cover 42 is manually pulled to leak out of the opening of the rotating box 4. The rotating box 4 can be controlled to move manually or by the second drive motor 12, so that the side at the opening is located on the ground, and the lithium battery will fall on the inclined bottom plate 13 and slide down, and the dried lithium battery needs to be collected manually. Finally, the box door 2 can be opened and the water-absorbing sponge 15 can be manually replaced.
