[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-3 , the present invention provides a technical solution: a ritonavir stirring crystallization kettle, including a kettle body 100 and a stirring unit 200 in the kettle body 100. The kettle body 100 is a conventional crystallization kettle for functions such as stirring and mixing, without other special uses, and will not be elaborated here.

[0031] Refer to Figure 1 , in a preferred implementation manner, for the stirring unit 200, the stirring unit 200 includes a driving motor 210 arranged at the upper part of the kettle body 100. The rotating shaft end of the driving motor 210 is in transmission connection with the connecting rod 220. The connecting rod 220 is vertically connected to the central part of the stirring mechanism 230. The rotating shaft end of the driving motor 210 is connected to the stirring mechanism 230 through the connecting rod 220 and drives the stirring mechanism 230 to rotate. When the stirring mechanism 230 rotates, it can stir the materials in the kettle body 100.

[0032] The outer wall of the stirring mechanism 230 is fixedly installed with a conduit 231. The conduit 231 does not contact the inner wall of the kettle body 100. When the conduit 231 rotates with the stirring mechanism 230, it will not contact the inner wall of the kettle body 100 and cause wear, etc., and can rotate stably.

[0033] Refer to Figure 1 ,Figure 2 In a preferred embodiment, the stirring mechanism 230 is arranged in a mountain shape. The outer walls of the vertical ends of the stirring mechanism 230 are evenly arranged with conduits 231. The mountain-shaped arrangement of the stirring mechanism 230 can have a larger contact area with the materials in the kettle body 100, driving more materials to move and be stirred. The two ends of the conduit 231 are respectively provided with an upper opening 2311 and a lower opening 23111. The lower opening 23111 of the conduit 231 faces obliquely downward, and the upper opening 2311 of the conduit 231 faces obliquely upward. The conduit 231 is inclinedly installed on the stirring mechanism 230. When the stirring mechanism 230 drives the conduit 231 to rotate, due to the action of centrifugal force, the materials at the conduit 231 move upward from the lower opening 23111 along the inside of the conduit 231 towards the upper opening 2311 and are finally discharged from the upper opening 2311.

[0034] Refer to Figure 1 、 Figure 2 In a further preference, a dispersion block 232 is fixedly installed inside the conduit 231. The dispersion block 232 is inclinedly installed in the conduit 231. The part of the dispersion block 232 facing the lower opening 23111 is arranged in a conical shape. The dispersion block 232 is arranged in a triangular pyramid shape. Through holes 2321 are arranged on all three surfaces of the dispersion block 232, and the through holes 2321 penetrate through the dispersion block 232. Through the conical arrangement of the dispersion block 232, the objects entering the conduit 231 can be divided into two parts, which respectively move towards the upper opening 2311 through the through holes 2321 at both ends of the dispersion block 232. Through a number of through holes 2321, the materials can be further subdivided. Repeating the above work can make the materials finer and the stirring and mixing more uniform.

[0035] One side of the bottom of the stirring unit 200 is fixedly installed with a self-rotation mechanism 300. The self-rotation mechanism 300 does not contact the inner wall of the kettle body 100. Through the self-rotation mechanism 300, it can contact the materials and rotate by itself, stirring the materials to a certain extent. The stirring mechanism 230 and the self-rotation mechanism 300 can be symmetrically installed on both sides of the stirring unit 200 according to requirements, or the stirring mechanism 230 and the self-rotation mechanism 300 can be arranged on one side or both sides of the stirring unit 200 according to requirements to change the stirring efficiency. Among them, arranging the stirring mechanism 230 and the self-rotation mechanism 300 on both sides of the stirring unit 200 can greatly improve the sufficiency of stirring the materials.

[0036] Refer to Figure 1 、 Figure 2, in a preferred embodiment, there is a rotation mechanism 300. The rotation mechanism 300 includes a fixing rod 310 connected to the stirring mechanism 230. At one end of the fixing rod 310 away from the stirring mechanism 230, a fixing block 320 is fixedly installed. A rotating rod 330 passing through the fixing block 320 is rotatably installed on the fixing block 320. The rotating rod 330 is connected to the fixing block 320 by bolts. Bolts are connected to both the upper and lower parts of the fixing block 320 for the rotating rod 330. By setting bolts above and below the fixing block 320, the remaining moving positions of the rotating rod 330 can be limited, keeping the rotating rod 330 capable of only horizontal rotation. On the outer wall of the bottom of the rotating rod 330, a stirring blade 331 is fixedly installed. The stirring blade 331 rotates with the rotating rod 330 under force to stir and mix the materials. The stirring blade 331 does not contact the stirring mechanism 230, and the stirring blade 331 will not collide with the stirring mechanism 230 during stirring, nor will it contact the inner wall of the kettle body 100, reducing wear and maintaining stable rotational stirring.
