Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] The present utility model provides a technical solution: As Figure 1 and Figure 4 shown, in this embodiment, a reaction kettle for drug preparation includes a reaction kettle body 1, a base 2 is fixedly connected below the reaction kettle body 1, a cover plate 3 is lapped above the reaction kettle body 1, a hydraulic telescopic device 5 is connected to the outer surface of the reaction kettle body 1, a connecting plate 4 is fixedly connected outside the cover plate 3, a clamping structure 6 is arranged inside the cover plate 3, a motor 9 is fixedly connected to the cover plate 3, the motor 9 is connected to the clamping structure 6, a stirring blade 8 is connected outside the clamping structure 6, a sealing structure 7 is connected to the reaction kettle body 1, the sealing structure 7 is clamped inside the cover plate 3, the sealing structure 7 is connected to the connecting plate 4, and the clamping structure 6 includes a driving rod 601, a sleeve 602 and a fixing ring 603. A limiting groove 604 is opened inside the driving rod 601, a limiting block 605 is fixedly connected inside the sleeve 602, and a bolt 1 606 is arranged inside the fixing ring 603.

[0021] As Figure 1 and Figure 3 shown, a feed pipe 10 is fixedly connected outside the reaction kettle body 1, the top end of the hydraulic telescopic device 5 is connected to the lower part of the connecting plate 4, a discharge pipe is connected below the base 2, one end of the driving rod 601 is connected to the output shaft of the motor 9, the sleeve 602 is sleeved outside the driving rod 601, the limiting block 605 is clamped inside the limiting groove 604, the fixing ring 603 is clamped inside the limiting groove 604, the fixing ring 603 overlaps with the limiting block 605, the fixing ring 603 overlaps with the sleeve 602, and the fixing ring 603 is connected to the driving rod 601 through the bolt 1 606.

[0022] By setting the limit groove 604, when the sleeve 602 and the fixing ring 603 are connected to the outer surface of the driving rod 601, the sleeve 602 will slide in the limit groove 604 through the limit block 605, and the fixing ring 603 will also overlap in the limit groove 604, so that the limit groove 604 plays a certain auxiliary role in fixing the sleeve 602 and the fixing ring 603, avoiding the phenomenon that the positions of the sleeve 602 and the fixing ring 603 shift during fixation.

[0023] As Figure 4 shown, the sealing structure 7 includes a sealing ring 701 and a guide rod 702. The sealing ring 701 is fixedly connected above the reaction kettle body 1. A column 704 is fixedly connected above the sealing ring 701.

[0026] When the reactor is preparing drugs, the sleeve 602 can be clamped into the limit groove 604 through the limit block 605, and the sleeve 602 will be sleeved on the surface of the driving rod 601. After the fixing ring 603 is clamped with the limit groove 604, it will contact the bottom of the sleeve 602, and the fixing ring 603 will fit with the bottom end of the driving rod 601. The fixing ring 603 will be threadedly connected to the driving rod 601 through the first bolt 606, so that the stirring blade 8 can be fixedly connected below the cover plate 3.

Subsequently, the drug is transported into the reactor body 1 through the feed pipe 10, and the driving rod 601 is driven to rotate by the motor 9. When the stirring blade 8 rotates, it will mix the drugs in the reactor body 1.
