The outer liner 13 can protect the inner liner 1 to prevent the inner liner 1 from being dented and deformed. When an object hits the outside of the outer liner 13, the spring 4 will use its own elasticity to make the top plate 2 press against the inner wall of the outer liner 13, thereby supporting the outside of the outer liner 13 to prevent the outside of the inner liner 1 from being dented. The spring 4 can also buffer external forces to reduce the impact force of objects, thereby further protecting the inner liner 1. The limiting sleeve 19 and the limiting sleeve rod 20 can limit the spring 4.

[0029] Embodiment 2: The two ends of the inner tank 1 are fixedly connected with a support block 10, and the two ends of the outside of the heating tube 3 are provided with a limit hoop 5. The bottom end and the top end of the support block 10 and the limit hoop 5 are respectively provided with a fixing hole 8, and the fixing hole 8 is provided with a fixing bolt 9.

The block 11 can facilitate the installation of the bottom 12 of the liner at the bottom of the inner liner 1 and the outer liner 13. The sealing ring 18 can increase the sealing between the inner liner 1 and the outer liner 13 to prevent the documents between the inner liner 1 and the heating tube 3 from being affected by the outside.

[0033] Working principle: when the utility model is in use, the heating tube 3 is arranged outside the inner tank 1 and between the support blocks 10. After the heating tube 3 is installed, the limiting hoop 5 is placed on both ends of the heating tube 3. When placing the limiting hoop 5, the fixing hole 8 inside the limiting hoop 5 is aligned with the fixing hole 8 inside the support block 10. After the fixing hole 8 is aligned, the fixing bolt 9 is screwed into the inside of the fixing hole 8 to fix the limiting hoop 5, so that the limiting hoop 5 can support and limit the heating tube 3, protect the heating tube 3 and prevent the heating tube 3 from being damaged. Then the outer tank 13 is placed outside the inner tank 1, and then the mounting bolt 15 is screwed into the inside of the first connecting plate 7 and the second connecting plate 14 to fix the first connecting plate 7 and the second connecting plate 14, so that the outer tank 13 and the inner tank 1 can be fixed. The reinforcing coating 6 is a Teflon coating. The reinforcing coating 6 It not only has moisture-resistant surface that is not stained by water and oil, but also has corrosion-resistant performance, so that the inner liner 1 can be protected. The block 11 can facilitate the installation of the liner bottom 12 at the bottom ends of the inner liner 1 and the outer liner 13. The sealing ring 18 can increase the sealing between the inner liner 1 and the outer liner 13 to prevent the documents between the inner liner 1 and the heating tube 3 from affecting the outside. The outer liner 13 can protect the inner liner 1 to prevent the inner liner 1 from being dented and deformed. When an object hits the outside of the outer liner 13, the spring 4 will use its own elasticity to make the top plate 2 press against the inner side wall of the outer liner 13, so as to support the outside of the outer liner 13 and prevent the outside of the inner liner 1 from being dented. The spring 4 can also buffer the external force to reduce the impact force of the object, so as to further protect the inner liner 1. The limiting sleeve 19 and the limiting sleeve rod 20 can limit the spring 4.
