Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery drying technology, and in particular to a drying device for lithium batteries. Background Technology
[0002] The essence of lithium battery drying is to reduce the moisture content in the material system to the level of one part per million (<1 ppm) through a precisely controlled physicochemical process. This process is not only related to the basic electrochemical performance of the battery, but also a key barrier to ensure safety and reliability.
[0003] Existing lithium battery drying equipment typically involves drying multiple lithium batteries at once. When multiple lithium batteries are stacked together, some batteries may not be fully dried. After drying for a while, the cabinet door needs to be opened manually to turn the batteries over so that they can be dried evenly. However, manually turning the batteries over is time-consuming and laborious. Furthermore, opening the cabinet door allows humid air from outside to enter the cabinet, which can cause the lithium batteries to become damp again. In addition, the high temperature inside the cabinet requires tools for workers to turn the batteries over, otherwise they may be burned. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Reference Figure 1-4 This utility model provides a drying device for lithium batteries, which includes a housing 1. A door 2 is rotatably connected to the front of the housing 1. The door 2 is shaped like an opening and a transparent glass block is fixedly connected to its inner side. A hot air blower 5 is fixedly connected to the left side of the housing 1. An air inlet pipe 6 is fixedly connected between the hot air blower 5 and the housing 1. An air outlet pipe 3 is fixedly connected to the outer side of the air outlet on the upper side of the housing 1. A shut-off valve 4 is provided on the outer side of the air outlet pipe 3.
[0024] The box 1 has an orifice-shaped block 7 inside. The upper and lower sides of the orifice-shaped block 7 are provided with several circular holes 8. The rear side of the orifice-shaped block 7 is fixedly connected to a block 16. The front side of the orifice-shaped block 7 is rotatably connected to a block 17. The left side of the orifice-shaped block 7 is fixedly connected to a rotating rod 9. The right side of the orifice-shaped block 7 is fixedly connected to a rotating rod 10. The right end of the rotating rod 10 passes through the box 1 and is fixedly connected to a disc 11. The left end of the rotating rod 9 is rotatably connected to the box 1. The rotating rod 10 is rotatably connected to the box 1. The right side of the disc 11 has two circular holes 12. The right side of the box 1 has a circular groove 13. The inside of the circular groove 13 and the corresponding circular hole 12 has a threaded rod 14. The right end of the threaded rod 14 is fixedly connected to a control block 15. The threaded rod 14 is threadedly connected to the box 1 and the disc 11.
[0025] A circular hole 18 is provided on the front side of block 16, and a circular hole 19 is provided on the front side of block 27. Several circular holes 18 and 19 are provided. A circular hole 20 is provided on the front side of block 27, and a circular groove 21 is provided on the front side of the orifice block 7. A threaded rod 22 is provided inside the circular groove 21 and the circular hole 20. A control block 23 is fixedly connected to the front end of the threaded rod 22. The threaded rod 22 is threadedly connected to block 27 and to orifice block 7.
[0026] After the lithium battery has been dried for a period of time, the worker observes it through the orifice block 7 of the door 2. Then, the worker holds the control block 15 and rotates the threaded rod 14 to create the circular hole 12 and the circular groove 13. Next, the worker holds the disc 11 and rotates the rotating rod 10, which in turn rotates the orifice block 7, which in turn rotates the rotating rod 9. All rotations are 180°. The 180° rotation of the orifice block 7 flips the battery. The diameters of the circular holes 18, 28, and 319 are all set to be smaller than the cross-sectional diameter of the cylindrical lithium battery. To prevent the lithium battery from falling out of the orifice block 7, the control block 15 is then held and rotated with the threaded rod 14 into the circular hole 12 and the circular groove 13 to fix the disc 11. The orifice block 7, circular hole 8, rotating rod 19, rotating rod 2 10, disc 11, threaded rod 14, block 16, and block 2 17 are designed to allow workers to evenly turn the lithium battery without opening the box door 2, thus ensuring even heating of the lithium battery. This reduces the workload of workers opening the box door 2 and using tools to turn the lithium battery, saving time and effort, and making it convenient and quick.
[0027] Working principle: When drying lithium batteries, the operator first opens the door 2, then holds control block 23 and rotates threaded rod 22 to open the circular groove 21 and circular hole 20. Next, square block 17 is rotated to place multiple lithium batteries into the inlet block 7. Square block 17 is then rotated to align the circular groove 21 and circular hole 20. Control block 23 is then held and threaded rod 22 is rotated to allow the batteries to enter the groove 21 and circular hole 20. At this point, door 2 is closed, and hot air fan 5 is started. The hot air exhausted by hot air fan 5 enters through air inlet pipe 6. The air inlet pipe 6 is located at the bottom of the housing 1, which facilitates the movement of hot air from bottom to top. At the same time, the shut-off valve 4 is controlled to allow the hot air to be discharged through the air outlet pipe 3. Initially, the shut-off valve 4 is fully opened to expel the cold air in the housing. Then, the shut-off valve 4 is closed to allow the hot air in the housing to stay for a while, which is conducive to drying the lithium battery. At the same time, the shut-off valve 4 is controlled to allow a portion of the gas to be discharged through the air outlet pipe 3, which is conducive to keeping the hot air for a longer period of time. The hot air enters the orifice block 7 through the first round hole 8, the second round hole 18, and the third round hole 19 to dry the battery.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
