An outlet pipe 193 is provided on the second distillation port 19, and a plurality of guide grooves 194 arranged in a linear array are opened in the outlet pipe 193.

[0026] Specifically, in use, the distillation reaction is carried out through the distillation vessel 1, and the gas produced by distillation is discharged through the first distillation port 13. It should be noted that the first distillation port 13 is installed on the top cover 11 of the distillation vessel 1, while the liquid is discharged through the second distillation port 19. At the same time, after the liquid enters the second distillation port 19, it is heated in the mounting groove 191 to prevent the liquid from solidifying in the second distillation port 19 and causing blockage. Meanwhile, multiple guide grooves 194 in the outlet pipe 193 guide the liquid and accelerate the discharge of the liquid.

[0027] In the above scheme, exhaust and liquid discharge are achieved through the first distillation port 13 and the second distillation port 19 on the distillation vessel 1. Multiple heating elements 192 are installed through the mounting groove 191 of the second distillation port 19. Liquid discharge is achieved through the outlet pipe 193 on the second distillation port 19.

[0029] Specifically, in use, the distillation reaction is carried out through the distillation vessel 1, and the gas produced by distillation is discharged through the first distillation port 13. It should be noted that the first distillation port 13 is installed on the top cover 11 of the distillation vessel 1, while the liquid is discharged through the second distillation port 19. At the same time, after the liquid enters the second distillation port 19, it is heated in the mounting groove 191 to prevent the liquid from solidifying in the second distillation port 19 and causing blockage. Meanwhile, multiple guide grooves 194 in the outlet pipe 193 guide the liquid and accelerate the discharge of the liquid.

[0030] As a further embodiment provided by this utility model, according to Figure 2 As shown, the bottom of the distillation vessel 1 is provided with a plurality of support columns 14 arranged in a circular array, and the bottom of the support columns 14 is provided with anti-slip pads 15.

[0031] Specifically, the distillation vessel 1 is supported by multiple support columns 14, and the anti-slip pads 15 at the bottom of the support columns 14 prevent the distillation vessel 1 from sliding during use.

[0032] As a further embodiment provided by this utility model, according to Figure 2 As shown, a motor 16 is installed at the bottom of the distillation vessel 1, and an output terminal 17 is installed on the motor 16. The output terminal 17 is located at the bottom of the distillation vessel 1.

[0036] Specifically, the motor 16 is started, and the output end 17 of the motor 16 drives the main rotating shaft 101 to rotate, which in turn drives multiple stirring rods 102 to rotate. Then, as the stirring rods 102 rotate, they drive multiple scrapers 103 to scrape the side wall of the distillation vessel 1 to prevent the material from adhering to the inner wall of the distillation vessel 1.

[0037] As a further embodiment provided by this utility model, according to Figure 2 As shown, the bottom of the distillation vessel 1 is provided with a plurality of support blocks 18 arranged in a circular array, and the support blocks 18 are located at the bottom of the motor 16.

[0038] Specifically, the motor 16 is supported by multiple support blocks 18.

[0039] Working principle: During use, the distillation reaction is carried out through the distillation vessel 1. The motor 16 is started, and the output end 17 of the motor 16 drives the main rotating shaft 101 to rotate, which in turn drives multiple stirring rods 102 to rotate. As the stirring rods 102 rotate, they drive multiple scrapers 103 to scrape the side wall of the distillation vessel 1 to prevent the material from adhering to the inner wall of the distillation vessel 1. The gas produced by distillation is discharged through the first distillation port 13. It should be noted that the first distillation port 13 is installed on the top cover 11 of the distillation vessel 1, while the liquid is discharged through the second distillation port 19. At the same time, after the liquid enters the second distillation port 19, it is heated in the mounting groove 191 to prevent the liquid from solidifying in the second distillation port 19 and causing blockage. Meanwhile, multiple guide grooves 194 in the outlet pipe 193 guide the liquid and accelerate the discharge of the liquid.
