Detailed Embodiment

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Refer to Figures 1 - 3, A drying device for the negative electrode material of a lithium battery, comprising a drying box 1. At the bottom of the inner side wall of the drying box 1, a motor 8 is fixedly connected. The driving end of the motor 8 is fixedly connected with a rotating column 9. Outside the rotating column 9, there is a rotating cylinder 11. The rotating cylinder 11 is provided with an arc-shaped opening. On the outer side wall of the rotating column 9, a positioning pin 13 passing through the arc-shaped opening is fixedly connected. The inner side wall of the drying box 1 is slidably connected with a placing plate 14. The bottom of the placing plate 14 is rotatably connected with the top of the rotating cylinder 11. On the inner side wall of the drying box 1, a plurality of heating elements 10 are fixedly arranged. The placing plate 14 is fixedly provided with a ventilation net 17. The inner side wall of the drying box 1 is fixedly connected with a pull-out plate 3. The pull-out plate 3 is provided with a sliding groove. Inside the sliding groove, a pull-out net plate 2 is slidably connected. The top of the placing plate 14 is fixedly connected with a fixing plate 12. On the top of the placing plate 14, a pushing plate 15 is slidably connected. The pushing plate 15 is connected to the fixing plate 12 through two threaded rods 16. A plurality of heating elements 10 are arranged at the bottom of the inner side wall of the drying box 1 and are evenly arranged on the left and right sides of the motor 8. The outer side wall of the positioning pin 13 is in contact with the inner side wall of the arc-shaped opening. The pushing plate 15 is located on the right side of the fixing plate 12. The two threaded rods 16 are arranged on the front and rear sides of the pushing plate 15. The lengths of the fixing plate 12 and the pushing plate 15 are greater than the width of the ventilation net 17. Place the lithium battery on the placing plate 14 and make the lithium battery contact the fixing plate 12. Rotate the threaded rod 16 to make the pushing plate 15 move vertically to the left. When the left side wall of the pushing plate 15 contacts the right side of the lithium battery and the threaded rod 16 cannot be rotated anymore, the fixing work of the lithium battery can be completed. When the temperature is too high, while reducing the temperature of the heating element 10, the motor 8 is used to rotate the rotating column 9. The rotation of the positioning pin 13 will make the rotating cylinder 11 move vertically upward through the arc-shaped opening and drive the placing plate 14 to move vertically upward, so that the lithium battery moves upward, increasing its distance from the heating element 10, thereby adjusting the temperature of the lithium battery, reducing the consumption of the battery liquid during drying, improving the quality of the lithium battery. The ventilation net 17 can effectively pass the temperature inside the drying box 1 through the placing plate 14 and transfer it to the lithium battery.

[0020] At the top of the drying box 1, a support frame 4 is fixedly connected. At the bottom of the support frame 4, a motor 7 is fixedly connected. The driving end of the motor 7 is fixedly connected with a disc 5. On the outer side wall of the disc 5, a plurality of fan blades 6 are fixedly arranged. The motor 7 is located directly above the drying box 1. The support frame 4 is in an L shape. The plurality of fan blades 6 are evenly arranged on the outer side wall of the disc 5. If the temperature is too high and cannot be quickly reduced in a short time, the motor 7 can be used to rotate the disc 5 and the fan blades 6, thereby generating downward wind energy, accelerating the air flow inside the drying box 1, accelerating the heat loss, and thus achieving the purpose of cooling.

[0021] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
