[0022] Embodiment 1

[0023] Please refer to Figures 1-4 As shown, a vacuum distillation device for indole methanol production includes a vacuum distillation tank 1. An air extraction pump 101 is fixedly installed on the outer side of the vacuum distillation tank 1. A condenser tube 103 is fixedly connected to the outer side of the vacuum distillation tank 1 through a valve. A prefabricated tank 2 is fixedly installed at the upper end of the vacuum distillation tank 1. The middle part of the lower end of the prefabricated tank 2 is fixedly connected to the connecting pipe 201 through a valve. The lower end of the connecting pipe 201 is fixedly connected to the upper end of the vacuum distillation tank 1. A stirring assembly 3 is installed inside the prefabricated tank 2. The stirring assembly 3 includes a stirring shaft 303. The stirring shaft 303 is rotatably connected to the inside of the prefabricated tank 2 through a bearing. A cleaning assembly 4 is installed on the outer side of the stirring shaft 303. The cleaning assembly 4 includes an installation frame 401. The installation frame 401 is fixedly installed on the outer side of the stirring shaft 303. A slide bar 402 is slidably connected to the inside of the installation frame 401. One end of the slide bar 402 extends to the outside of the installation frame 401 and is fixedly connected to a cleaning brush 405.

[0024] In this solution, the compounds required for the production of indole methanol can be premixed inside the prefabricated tank 2, and the compounds can be stirred by the stirring shaft 303, so as to uniformly mix various compounds and fully react. The vacuum distillation tank 1 can heat and distill the compounds, and the air pump 101 can suck out the air inside the vacuum distillation tank 1, thereby reducing the pressure inside the vacuum distillation tank 1. The condenser pipe 103 can liquefy the evaporated gas inside the vacuum distillation tank 1. When the distillation in the vacuum distillation tank 1 is completed, the valve at the connecting pipe 201 is opened, so that the compounds inside the prefabricated tank 2 enter the inside of the vacuum distillation tank 1, and there is no need to add various compounds again for stirring reaction, saving the time required for the mixing reaction of the compounds, and thus increasing the distillation efficiency of the vacuum distillation tank 1. After all the compounds inside the prefabricated tank 2 are completely added to the vacuum distillation tank 1, the installation frame 401 is driven to rotate by the stirring shaft 303, so that the sliding rod 402 drives the cleaning brush 405 to rotate and clean the inner wall of the prefabricated tank 2, preventing the residual compounds from affecting the next mixing operation and ensuring the correct ratio of the compound mixing.

[0025] Example 2

[0026] Please refer to Figure 3 As shown, the other end of the sliding rod 402 extends to the inside of the installation frame 401 and is fixedly connected with a limit cover 404. A cleaning spring 403 is sleeved on the outer side of the sliding rod 402, and both ends of the cleaning spring 403 are fixedly connected with the limit cover 404 and the installation frame 401 respectively. The outer side of the cleaning brush 405 is closely attached to the inner wall of the prefabricated tank 2.

[0027] In this solution, the cleaning spring 403 can pull the sliding rod 402 through the limit cover 404 so that the cleaning brush 405 can be closely attached to the inside of the prefabricated tank 2, thereby increasing the cleaning effect of the cleaning brush 405 on the prefabricated tank 2.

[0028] Example 3

[0029] Please refer to Figure 2 As shown, the stirring assembly 3 further includes a stirring motor 301. Pulley 302 is fixedly connected to the top of both the stirring motor 301 and the stirring shaft 303. The two pulleys 302 are connected by a belt in transmission, and at least four stirring rods 304 are fixedly connected to the outer side of the stirring shaft 303.

[0030] In this solution, the stirring motor 301 is electrically connected to an external power supply. By starting the stirring motor 301, the stirring shaft 303 can be driven to rotate under the transmission of the two pulleys 302 and the belt, and then the stirring rods 304 can be driven to stir the compounds inside the prefabricated tank 2.

[0031] Example 4

[0032] Please refer to Figure 2 AndFigure 4 As shown in the figure, two feed pipes 202 are fixedly connected to the upper end of the prefabricated tank 2, and a water outlet pipe 203 is fixedly connected to the outer side of the lower end of the prefabricated tank 2 through a valve.

[0033] A discharge hopper 104 is fixedly installed at the lower end of the vacuum distillation tank 1, and a discharge valve 102 is fixedly connected to the lower end of the discharge hopper 104.

[0034] In this solution, the compound raw material can be added to the inside of the prefabricated tank 2 through the feed pipe 202. By opening the valve of the water outlet pipe 203, the clean compound in the prefabricated tank 2 can be discharged through the water outlet pipe 203. After the vacuum distillation in the vacuum distillation tank 1 is completed, by opening the discharge valve 102, the purified compound can be discharged to the outside through the discharge valve 102 for subsequent processing operations.

[0035] The working principle and usage process of the present utility model are as follows: First, when the vacuum distillation tank 1 is performing distillation, all valves are in a closed state. Then, start the air extraction pump 101, which can suck out the air inside the vacuum distillation tank 1, thereby reducing the pressure inside the vacuum distillation tank 1 and distilling the compound inside the vacuum distillation tank 1. Then, open the valve at the condenser pipe 103 to liquefy the volatile gas inside the vacuum distillation tank 1. When the distillation in the vacuum distillation tank 1 is completed, open the discharge valve 102 to discharge the purified compound to the outside through the discharge valve 102 for subsequent processing operations. Then, open the valve at the connecting pipe 201 to allow the compound inside the prefabricated tank 2 to enter the inside of the vacuum distillation tank 1, saving the time required for the compound to mix and react. When the compound inside the prefabricated tank 2 is completely added to the vacuum distillation tank 1, close the valve at the connecting pipe 201 and start the stirring motor 301 to drive the stirring shaft 303 so that the cleaning brush 405 rotates to clean the inner wall of the prefabricated tank 2. The cleaned compound is discharged through the water outlet pipe 203. Moreover, through the feed pipe 202, the prefabricated tank 2 is refilled again, and the stirring rod 304 is driven by the stirring shaft 303 to stir and mix the compound to facilitate the next distillation and feeding operation, greatly increasing the distillation efficiency of the vacuum distillation tank 1.
