The half-white ceramic reflective layer short-wave heating tube is connected to the connecting seat 1. Both ends of the upper auxiliary heating sleeve 4 are coated with an insulating coating 5. The insulating coating 5 is used to prevent the heating wire inside the half-white ceramic reflective layer short-wave heating tube from short-circuiting with the metal shell of the sleeve. The left end of the fixing seat 2 is sealed. Two lower connecting rings 6 are provided below the surface, and the two lower connecting rings 6 are fixedly connected to the left side of the fixing base 2. The two lower connecting rings 6 are arranged in a straight line, and a lower auxiliary heating sleeve 7 is inserted into the lower connecting ring 6. The left end of the lower auxiliary heating sleeve 7 is sealed and the right end is open. The right end of the lower auxiliary heating sleeve 7 is inserted into the lower connecting ring 6. The lower auxiliary heating sleeve 7 is also made of silicon carbide. The lower auxiliary heating sleeve 7 has a half-white ceramic reflective layer shortwave heating tube inside. Both ends of the lower auxiliary heating sleeve 7 are also coated with an insulating coating 5. Two thermocouples are provided on both sides between the upper auxiliary heating sleeve 4 and the lower auxiliary heating sleeve 7. 8.

A protective component is provided on the upper auxiliary heating sleeve 4 to protect its surface from scratches and impacts, improving its service life and enhancing safety. The protective component includes a connecting plate 10 and a protective mesh cover 15. In use, the upper auxiliary heating sleeve 4 and lower auxiliary heating sleeve 7 are sequentially fixed onto the fixing base 2. Then, the graphite boat body containing the battery cells is placed on the support tubes 9. The furnace body and connecting base 1 are then sealed in contact. Auxiliary heating of the graphite boat is then provided by the short-wave heating tubes with a half-sided white ceramic reflective layer inside the upper auxiliary heating sleeve 4 and lower auxiliary heating sleeve 7, and the temperature is monitored by thermocouple 8.

[0025] like Figure 1 and Figure 3 As shown, a connecting plate 10 is provided at the left end of the upper auxiliary heat jacket 4. The diameter of the connecting plate 10 is the same as the diameter of the upper auxiliary heat jacket 4. The right end of the connecting plate 10 is fixedly connected to the left end of the upper auxiliary heat jacket 4. An external thread 11 is provided on the side of the connecting plate 10. Figure 3As shown, a limiting ring 12 is fitted on the outer side of the connecting plate 10. The inner side of the limiting ring 12 is fixedly connected to the outer side of the connecting plate 10, and the limiting ring 12 is located at the rightmost end of the connecting plate 10. A screw ring 13 is fitted on the connecting plate 10. The inner side of the screw ring 13 is provided with an internal thread 14 corresponding to the external thread 11. The screw ring 13 is screwed onto the connecting plate 10 through the internal thread 14. The maximum diameter of the screw ring 13 is greater than the maximum diameter of the limiting ring 12. A protective mesh cover 15 is provided on the right side of the connecting plate 10. The protective mesh cover 15 is made of high-temperature resistant material with good wear resistance. The left end of the protective mesh cover 15 is fixedly connected to the right side of the connecting plate 10. The maximum diameter of the protective mesh cover 15 is the same as the maximum diameter of the screw ring 13. The inner diameter of the protective mesh cover 15 is larger than the maximum diameter of the limiting ring 12. Therefore, when the screw ring 13 is screwed onto the connecting plate 10, the protective mesh cover 15 is fitted onto the outside of the limiting ring 12 and will not be blocked by the limiting ring 12. The protective mesh cover 15 is provided with multiple through holes 16, which are used to enhance heat dissipation and allow the temperature of the upper auxiliary heating sleeve 4 to dissipate without being affected.

At this time, the positioning block 19 at the right end of the upper auxiliary heating jacket 4 will have enough length to be inserted into the upper connecting ring 3, which will not affect the normal installation and fixation of the upper auxiliary heating jacket 4. Figure 2 and Figure 3 As shown, the left side of the positioning block 19 is provided with an annular groove 21, and the inner side of the annular groove 21 is provided with an external thread 22 corresponding to the internal thread 18. The fixing ring 17 can be fixed in the annular groove 21 by screwing the internal thread 18. The lower auxiliary heating sleeve 7 is provided with the same protective components as the upper auxiliary heating sleeve 4. When in use, the screw ring 13 is screwed onto the connecting plate 10. At this time, the protective mesh cover 15 will be placed on the upper auxiliary heating sleeve 4, and the protective mesh cover 15 will not contact the upper auxiliary heating sleeve 4. While the screw ring 13 is screwed inward on the connecting plate 10, the fixing ring 17 at the right end of the protective mesh cover 15 will be inserted into the annular groove 21 on the left side of the positioning block 19, and will screw inward with the rotation of the screw ring 13. When the right end of the screw ring 13 abuts against the limiting ring 12, the installation and fixing of the protective mesh cover 15 is completed. This setting can protect the surface of the upper auxiliary heating sleeve 4 from scratches and bumps, improve the service life of the sleeve, and enhance the safety during use. At the same time, the detachable design will not affect the normal maintenance of the sleeve, and enhance the convenience of the protective component.
