[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the utility model proposes a stirring structure of a fluorination reactor, comprising a reactor 1, wherein the reactor 1 is configured as a can-shaped structure with an upper opening, a support block 101 is fixedly provided on the side of the reactor 1, and further comprising a lifting and rotating mechanism 2 and a stirring mechanism 3, wherein the lifting and rotating mechanism 2 is arranged on the support block 101, the lifting and rotating mechanism 2 comprises a guide tube 202 and a connecting tube 204, wherein the lower end of the guide tube 202 is fixedly connected to the upper part of the support block 101, the connecting tube 204 and the guide tube 202 are movably connected, a connecting frame 205 is fixedly provided on the outside of the connecting tube 204, and the stirring mechanism 3 is arranged on the connecting frame 205.

[0024] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the guide tube 202 is set as a tubular structure, a slide groove 203 is opened on the guide tube 202, the connecting tube 204 is set as a tubular structure, the connecting tube 204 and the guide tube 202 are slidably connected outside, a slider 207 is fixed inside the connecting tube 204, the slider 207 and the slide groove 203 are slidably connected to limit the moving direction of the slider 207 and the connecting tube 204, the slide groove 203 is an inverted L-shaped groove, and the thickness of the upper transverse groove of the slide groove 203 is greater than that of the slider 207. The thickness of the slider 207 is fixedly provided with a connecting block 206 on the inner side, and the connecting block 206 is set as a tubular structure. The connecting block 206 is slidably connected to the inner wall of the guide tube 202, and a screw rod 208 is provided inside the guide tube 202. The lower part of the screw rod 208 is rotatably connected to the support block 101 and passes through the support block 101. The lower part of the support block 101 is provided with a first motor 201, and the first motor 201 and the screw rod 208 are axially connected. The inner side of the connecting block 206 is threadedly connected to the screw rod 208.

[0025] like Figure 1 , Figure 3 and Figure 4As shown, the stirring mechanism 3 includes a second motor 301 and a stirring roller 302. The second motor 301 is arranged on the upper part of the connecting frame 205. The stirring roller 302 is rotatably connected to the lower part of the connecting frame 205 and penetrates the connecting frame 205. The stirring roller 302 and the second motor 301 are axially connected to assist stirring for fluorination reaction.

[0026] In specific use, after the raw materials are added to the reactor 1, the first motor 201 is started to rotate the screw rod 208.
