Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figure 1-4 A purification apparatus for methylindole includes a base 1, an extraction vessel 2 fixedly connected to the left side of the top of the base 1, an inlet 3 at the top of the extraction vessel 2, a first outlet pipe 4 at the bottom right side of the extraction vessel 2, a distillation vessel 5 fixedly connected to the right side of the extraction vessel 2, a first inlet pipe 6 at the left side of the distillation vessel 5, a pump 7 fixedly connected between the extraction vessel 2 and the inlet 3, a first connecting pipe 8 fixedly connected between the first outlet pipe 4 and the pump 7, and a connection between the first inlet pipe 6 and the pump 7. There is a second connecting pipe 9. A heating seat 10 is fixedly connected to the right side of the top of the base 1. A heating pipe 11 is installed inside the heating seat 10. A gas collecting plate 12 is fixedly connected to the top of the distillation vessel 5. A liquid collecting tank 15 is fixedly connected to the right side of the distillation vessel 5. A third connecting pipe 13 is fixedly connected to the top of the distillation vessel 5 and the top of the liquid collecting tank 15. A condenser pipe 14 is sleeved on the outside of the third connecting pipe 13. A control seat 16 is fixedly connected to the middle of the base 1. A control button 29 is fixedly connected to the front end of the base 1.

[0025] The feed inlet 3, extraction vessel 2, and first liquid outlet pipe 4 are internally connected; the distillation vessel 5, third connecting pipe 13, and collection tank 15 are internally connected; the liquid pump 7 is electrically connected to the control base 16; the control button 29 is electrically connected to the control base 16; the heating tube 11 is electrically connected to the control base 16; and the top of the heating base 10 is tightly fitted to the top of the base 1.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, in use, crude methylindole is placed in extraction vessel 2. First, a high-density organic solution is added to dissolve the crude methylindole, and then a low-density organic solution that is insoluble in methylindole is added. After thorough stirring and allowing the layers to settle and separate, the pump 7 is started. The pump 7 draws the lower layer of organic solvent containing methylindole into distillation vessel 5. The control seat 16 starts the heating tube 11, and the heating seat 10 heats the distillation vessel 5. By adjusting different heating temperatures, a condenser 14 is connected to the outside of the third connecting pipe 13. When methylindole reaches its boiling point, it enters the collection tank 15 in gaseous form through the third connecting pipe 13, thereby achieving the purification of methylindole. The pump 7 and the control seat 16 are electrically connected. This technology is existing technology and will not be described in detail.

[0027] A limiting seat 17 is fixedly connected to the left side of the bottom inside the base 1. A servo motor 18 is installed on the top of the limiting seat 17. A rotating seat 19 is movably connected to the top of the servo motor 18. A first magnet 20 is fixedly connected inside the rotating seat 19. A movable block 21 is movably connected to the bottom inside the extraction vessel 2. A second magnet 22 is fixedly connected inside the movable block 21. The servo motor 18 is electrically connected to the control seat 16. The first magnet 20 and the second magnet 22 attract each other. The output end of the servo motor 18 is connected to the rotating seat 19.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, when mixing crude methylindole with an organic solution, manual shaking is laborious. Stirring with a stirring blade can easily cause the liquid to stick to the blade. By activating the servo motor 18, the servo motor 18 drives the rotating seat 19. A first magnet 20 is fixedly connected inside the rotating seat 19, and a movable block 21 is movably connected to the bottom of the extraction vessel 2. A second magnet 22 is fixedly connected inside the movable block 21. The first magnet 20 and the second magnet 22 attract each other, causing the first magnet 20 to drive the second magnet 22 to rotate, thereby achieving stirring of the liquid inside the extraction vessel 2. The servo motor 18 is electrically connected to the control seat 16. This technology is existing and will not be described further.

[0029] An installation base 23 is fixedly connected to the top of the extraction vessel 2. Two sets of solvent tanks 24 are fixedly connected to the top of the installation base 23. A second liquid outlet pipe 25 is opened at the bottom of the two sets of solvent tanks 24. A flow meter 26 is fixedly connected inside the second liquid outlet pipe 25. Two sets of second liquid inlet pipes 27 are opened on both sides of the top of the extraction vessel 2.

The two sets of solenoid valves 28 are electrically connected to the control base 16.

[0030] Specifically, such as Figure 1 and Figure 4 As shown, in use, two different organic solutions are placed in different solvent tanks 24. The flow meter 26 is activated by the control seat 16 to effectively control the amount of organic solution. When the specified value is reached, the solenoid valve 28 is activated to close it, thereby achieving accurate control of the organic solvent and improving the accuracy of the reaction. The flow meter 26 and the control seat 16 are electrically connected, and the solenoid valve 28 and the control seat 16 are also electrically connected. This technology is existing technology and will not be described in detail.

[0031] Working Principle: In use, this invention first places crude methylindole in extraction vessel 2. A high-density organic solution is then added to dissolve the crude methylindole, followed by the addition of a low-density organic solution that is insoluble in methylindole. The mixture is thoroughly stirred until it settles and separates into layers. Then, pump 7 is activated, drawing the lower layer of organic solvent containing methylindole into distillation vessel 5. Control unit 16 activates heating tube 11, and heating unit 10 heats distillation vessel 5. By adjusting different heating temperatures, a condenser 14 is connected to the outside of the third connecting pipe 13. When methylindole reaches its boiling point, it enters the collection tank 15 as a gas through the third connecting pipe 13, thus purifying the methylindole. Secondly, manually shaking the crude methylindole with the organic solution is laborious; therefore, a more efficient method is used… When the stirring blades are stirring, the liquid can easily stick to them. By starting the servo motor 18, the servo motor 18 drives the rotating seat 19. The rotating seat 19 is fixedly connected to the first magnet 20, and the bottom of the extraction vessel 2 is movably connected to the movable block 21. The movable block 21 is fixedly connected to the second magnet 22. The first magnet 20 and the second magnet 22 attract each other, and the first magnet 20 drives the second magnet 22 to rotate, thereby stirring the liquid in the extraction vessel 2. At the same time, during use, the two different organic solutions are respectively placed in different solvent tanks 24. By starting the flow meter 26 through the control seat 16, the amount of organic solution can be effectively controlled. When the specified value is reached, the solenoid valve 28 is activated to close it, thereby achieving accurate control of the organic solvent and improving the accuracy of the reaction.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
