A fixed plate 13 is fixed to the lower end of the stirring rod 10, and a scraper 14 is fixed to the end of the fixed plate 13 away from the stirring rod 10. A stirring assembly is provided in the conveying pipe 8. The stirring assembly includes a second motor 16 fixed to one end of the conveying pipe 8. The output end of the second motor 16 is deep in the conveying pipe 8 and is fixedly connected to the conveying rod 17. The conveying rod 17 corresponds to the stirring rod 10.

[0039] When the reflux reactor is in use, the temperature inside the barrel body 1 is detected by the temperature sensor 24 and fed back to the controller 6 in real time, so that the raw materials are within the appropriate temperature range and facilitate the reaction. During the detection, the heat inside the barrel body 1 is extracted through the heat conducting plate 20 and transferred to the exchanger 21. The exchanger 21 transfers the heat to the heat transfer plate 22, so that the heat transfer plate 22 conducts heat to the delivery pipe 8, which is convenient for preheating the medicine and reducing heat waste. The heat is conveniently transferred to the delivery pipe 8 through the heating pipe 9.

[0040] The implementation principle of a reflux reactor in this embodiment is as follows: when the reflux reactor is used, the valve in the feed pipe 7 is opened and the valve in the discharge pipe 4 is closed. The staff pours the pharmaceutical raw materials to be processed into the feed pipe 7, which enters the barrel 1 through the connecting pipe 3. After closing the valve, the heating pipe 9 is started to heat the raw materials. At the same time, the motor 5 is started, and the motor drives the stirring rod 10 to stir the raw materials. After the stirring is completed, the valve in the discharge pipe 4 is opened to discharge the raw materials.

[0041] When the reflux reactor is in use, when the stirring rod 10 rotates, the stirring blade 11 is driven to rotate, and at the same time, the fixed plate 13 and the scraper 14 are driven to rotate, so that the vertical rod 12 rotates, so as to facilitate uniform mixing of the raw materials, reduce precipitation, improve the mixing effect, and facilitate stirring. At the same time, the second motor 16 is started, and the second motor 16 rotates to drive the conveying rod 17 to rotate, so that the conveying blade 18 and the mixing rod 19 rotate, and the raw materials entering the conveying pipe 8 are uniformly mixed, thereby improving the mixing effect and facilitating the uniform reaction of the raw materials.

[0042] When the reflux reactor is in use, the temperature inside the barrel body 1 is detected by the temperature sensor 24 and fed back to the controller 6 in real time, so that the raw materials are within the appropriate temperature range and facilitate the reaction. During the detection, the heat inside the barrel body 1 is extracted through the heat conducting plate 20 and transferred to the exchanger 21. The exchanger 21 transfers the heat to the heat transfer plate 22, so that the heat transfer plate 22 conducts heat to the delivery pipe 8, which is convenient for preheating the medicine and reducing heat waste. The heat is conveniently transferred to the delivery pipe 8 through the heating pipe 9. When the temperature is abnormal, the controller 6 controls the exchanger 21 to adjust the temperature inside the barrel body 1 and lower the temperature of the heating pipe 9. The scraper 14 moves, driving the scraper 15 to scrape the inner wall of the barrel body 1 and the connecting pipe 3 to reduce contamination and residue of the raw materials.
