[0022] The concave heat preservation shell 6 is composed of two transverse heat preservation shells 12 and a longitudinal heat preservation shell 13. The front surface of the transverse heat preservation shell 12 and the left surface of the longitudinal heat preservation shell 13 are provided with an opening 9 and a sealing assembly 15. The opening 9 is used to provide an operating space for the installation of an external guide pipe. The sealing assembly 15 completely seals the opening 9 when the vaporizer is in use. The sealing assembly 15 is composed of a sealing plate 10 and a sealing ring 11. The surface of the sealing ring 11 is in close contact with the inner wall of the opening 9. The width of the sealing ring 11 is greater than the thickness of the front wall of the transverse heat preservation shell 12. The surface of the sealing ring 11 is provided with a clamping groove. The part of the front wall of the transverse heat preservation shell 12 at the opening 9 is located inside the clamping groove of the sealing ring 11. The sealing assembly 15 is used to seal the opening 9 and reduce the risk of heat leakage through the opening 9 to harm the workers.

[0023] The two transverse heat preservation shells 12 are fixedly connected with a waste heat exhaust assembly 14. The upper and lower ends of the waste heat exhaust assembly 14 penetrate into the interiors of the two transverse heat preservation shells 12. The waste heat exhaust assembly 14 is composed of a gas guide pipe and an external interface. The external interface is located at the rear wall of the gas guide pipe. The upper and lower ends of the gas guide pipe penetrate into the interiors of the two transverse heat preservation shells 12. The waste heat exhaust assembly 14 is used to provide conditions for further processing of waste heat.

[0024] The left surface of the transverse heat preservation shell 12 is fixedly connected with a corrugated heat preservation sleeve 7. The corrugated heat preservation sleeve 7 penetrates the transverse heat preservation shell 12.

The conical sealing sleeve 8 is used to improve the sealing effect of the corrugated heat preservation sleeve 7.

[0025] Working principle: When the vaporizer guide pipe and the gas outlet pipe are installed, the edge of the sealing ring 11 is first manually compressed to assist in pulling out the sealing plate 10. Then the guide pipe penetrates the conical sealing sleeve 8 and the corrugated heat preservation sleeve 7. Then the guide pipe is connected with the feeding pipe interface 3 and the gas outlet pipe interface 5 through the opening 9. After the guide pipe is installed, the sealing plate 10 is reset. During the use of the vaporizer, the waste heat is discharged through the heat exhaust port 4. The discharged heat is transferred in the interiors of the concave heat preservation shell 6 and the corrugated heat preservation sleeve 7 to improve the heat preservation effect of the area near the vaporizer main body 2. Because the heat preservation performance of the corrugated heat preservation sleeve 7 is lower than that of the concave heat preservation shell 6, the temperature decreases as it moves away from the vaporizer main body 2. Due to the communication relationship, the temperature does not suddenly change. Therefore, the temperature of the internal objects of the feeding pipe and the gas outlet pipe changes uniformly and slowly, thereby reducing the risk of crystallization.

[0026] The utility model embodiment has been explained in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiment, still can make various changes in the knowledge range possessed by the ordinary skilled in the art without departing from the utility model's tenet.
