[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figures 1-4 , a heat-insulating stirring device for preparing dextrorotatory phenylethylamine, comprising a box body 1, the box body 1 being a cavity structure, the box body 1 being provided with two through holes, the two through holes being fixedly mounted with a liquid inlet pipe 2 and a liquid outlet pipe 3, the outer wall of the box body 1 being fixedly mounted with a drying box 9 and a filter box 10, a cover plate 5 being provided on the upper part of the box body 1, a detachable driving motor 11 being mounted on the upper part of the cover plate 5, when the cover plate 5 needs to be opened, the driving motor 11 is first removed, and then the cover plate 5 is taken out, the driving end of the driving motor 11 is fixedly connected with a first rotating rod 12, the outer wall of the first rotating rod 12 is fixedly connected with a fixing rod 19, the fixing rod 19 is fixedly connected with a stirring blade 20, a reaction tank 23 is provided inside the box body 1, a cooling pipe 21 and a heating wire 22 are provided between the outer wall of the reaction tank 23 and the inner wall of the box body 1, the liquid inlet pipe 2 and the liquid outlet pipe 3 are respectively fixedly connected with the cooling pipe 21;

[0023] Two handles 6 and a vacuum pump 7 are fixedly installed on the upper part of the cover plate 5. Four limiting clamps 4 are clamped between the upper part of the cover plate 5 and the upper end of the box body 1 for limiting the position. When the cover plate 5 is to be opened, the nuts in the limiting clamps 4 are screwed to reduce the limiting force of the limiting clamps 4 on the cover plate 5. A pipe 8 is provided in a movable sleeve of the vacuum pump 7.

[0024] The outer wall of the first rotating rod 12 is fixedly connected with a sleeve 18, and the sleeve 18 is provided with a through hole, in which a fixing rod 19 is provided. The lower part of the first rotating rod 12 is fixedly connected with a vertical bevel gear 24, and the lower part of the sleeve 18 is rotatably connected with the pipe fitting 13, and the second rotating rod 14 and the third rotating rod 15 are rotatably connected in the pipe fitting 13. The second rotating rod 14 and the third rotating rod 15 are respectively rotatably connected to the inner wall of the reaction tank 23. When the driving motor 11 drives the first rotating rod 12 to rotate, the sleeve 18 will rotate accordingly. The pipe fitting 13 rotatably connected at the lower part of the sleeve 18 is kept stable by being rotatably connected to the second rotating rod 14 on the reaction tank 23. Therefore, when the vertical bevel gear 24 rotates, the first transverse bevel gear 25 and the second transverse bevel gear 26 meshing with the vertical bevel gear 24 rotate accordingly;

[0025] The second rotating rod 14 is fixedly connected to the first transverse bevel gear 25, and the third rotating rod 15 is fixedly connected to the second transverse bevel gear 26. The first transverse bevel gear 25 and the second transverse bevel gear 26 are meshed and connected with the vertical bevel gear 24. The second rotating rod 14 and the third rotating rod 15 are respectively fixedly connected to the connecting rod 16, and the two ends of the connecting rod 16 are respectively fixedly connected to the stirring rod 17;

[0026] The drying box 9 and the filter box 10 are connected to the pipe 8, and the sleeve 18 is rotatably connected to the cover plate 5. When the drive motor 11 rotates, the first rotating rod 12 rotates accordingly, thereby driving the sleeve 18 to rotate. The pipe 13 is rotatably connected to the lower end of the sleeve 18. The pipe 13 is fixed by rotating the second rotating rod 14 connected to the inner wall of the reaction tank 23. Therefore, when the sleeve 18 rotates, the pipe 13 remains stationary;

[0027] Four limiting clamps 4 are equidistantly distributed on the cover plate 5 circumference, nuts and screws are respectively provided inside the four limiting clamps 4 , and two handles 6 are horizontally symmetrically distributed on the cover plate 5 .

[0028] The functional principle of this utility model can be explained through the following operation modes:

[0029] Open the limiting clamp 4, remove the cover plate 5 through the handle 6, then add the stirring liquid, turn on the vacuum pump 7, and allow air to enter the vacuum pump 7 from the pipe 8, and then enter the reaction tank 23 through the vacuum pump 7. When the air enters from the pipe 8, it will first pass through the drying box 9 to dry the moisture in the air, and then enter the filter box 10 to filter out the gas in the air that may interfere with the reaction, and finally enter the reaction tank 23;

[0030] Turn on the drive motor 11, so that the driving end of the drive motor 11 drives the first rotating rod 12 to rotate. When the first rotating rod 12 rotates, it drives the vertical bevel gear 24 at the bottom to rotate. When the vertical bevel gear 24 rotates, the first transverse bevel gear 25 and the second transverse bevel gear 26 on both sides of it that are meshed and linked will rotate accordingly, and when rotating, the second rotating rod 14 and the third rotating rod 15 on both sides are driven to rotate. When the second rotating rod 14 and the third rotating rod 15 rotate, the connecting rods 16 on both sides thereof will make circular motions with the second rotating rod 14 and the third rotating rod 15 as the center, respectively. Therefore, the stirring rods 17 at both ends of the connecting rod 16 will stir the stirring liquid up and down, so that the temperature of the stirring liquid in the upper and lower parts is more balanced.

[0031] When the stirring liquid reacts to a certain extent, small water droplets will be generated on the inner wall of the reaction tank 23. There will be some stirring liquid in the small water droplets, which will be scraped off by the stirring blade 20 to allow the reaction to proceed fully.

[0032] The heating wire 22 is turned on to maintain a certain temperature of the heating wire 22, so that the reaction tank 23 will maintain the same temperature as the heating wire 22, thereby achieving the effect of heat preservation. When the reaction tank 23 needs to be cooled, the coolant enters the cooling pipe 21 from the liquid inlet pipe 2 and then flows out from the liquid outlet pipe 3. During the outflow process of the coolant, the heat will be taken away, thereby achieving the cooling effect.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
