[0026] Working principle:

[0027] The first step: a mixing rotating rod 4 is rotated and sleeved inside the reaction kettle body 1, and a plurality of first mixing plates 5 are fixedly installed outside the mixing rotating rod 4. Then, a driving motor 7 is fixedly installed at the bottom of the reaction kettle body 1 and is fixedly connected to the mixing rotating rod 4, so that the drugs inside the reaction kettle body 1 are mixed;

[0028] Step 2: A lifting frame 601 is movably sleeved on the outside of the mixing rod 4, and a plurality of second mixing plates 607 are fixedly installed on the outer wall of the lifting frame 601, and the transmission plate 602 on the outside of the mixing rod 4 is slidably sleeved with the lifting frame 601, so that the mixing rod 4 rotates and drives the lifting frame 601 to rotate;

[0029] Step 3: A lifting frame 603 is rotatably sleeved on the outside of the lifting rotating frame 601, and a servo hydraulic cylinder 606 is provided on the top of the reactor body 1, so that the lifting frame 605 outside the lifting frame 603 is fixedly connected to the servo hydraulic cylinder 606, thereby adjusting the position of the second mixing plate 607, achieving sufficient mixing and stirring of the drugs on the upper part of the reactor body 1 while reducing the stirring resistance, thereby accelerating the efficiency of drug mixing;

[0030] The operation method of injecting the medicine through the filling pipe 10 is as follows:

[0031] In the first step, a filling pipe 10 is fixedly installed inside the support frame 3 so that one end of the filling pipe 10 is connected to the reactor body 1;

[0032] Step 2: A sealing baffle 902 is fixedly installed on the inner wall of the filling pipe 10, and a connecting pipe 904 is movably connected thereto through a sealing ring sleeve 903. A plurality of through-hole grooves 905 are provided on the outside of the connecting pipe 904, so that the drug enters the interior of the reactor 1 through the through-hole grooves 905;

[0033] Step 3: An adjusting screw 908 is connected to the connecting pipe 904 through the sealing thread sleeve inside the filling pipe 10. By adjusting the position of the through hole groove 905, when the through hole groove 905 is on the right side of the sealing ring sleeve 903, the filling drug enters the connecting pipe 904 through the through hole groove 905 and enters the inside of the reactor body 1. On the contrary, when the through hole groove 905 is moved to the left side of the sealing ring sleeve 903, the drug stops entering the inside of the reactor 1 through the through hole groove 905. By adjusting the time for the connecting pipe 904 to move to the right, the drug filling amount can be quickly adjusted.

[0034] Step 4: A discharge valve 909 is fixedly connected to the bottom end of the filling pipe 10 so that the medicine retained in the filling pipe 10 can be quickly discharged, and the filling of the medicine can be manually controlled. After the filling, the medicine is stopped, and the retained medicine is discharged to prevent the medicine from being retained for a long time, which may cause drug contamination.
