The adjustment assembly includes a connecting post 211 rotatably inserted into the inner cavity of the connecting pipe 202. One end of the connecting post 211 extends downward into the inner cavity of the housing 204. A second bevel gear 210 is fixedly connected to one end of the connecting post 211 located in the inner cavity of the housing 204. A rotating post 208 is fixedly connected to one end of each of the several sets of blades 205. The rotating post 208 rotatably passes through the housing 204. A second bevel gear 209 is fixedly connected to one end of each rotating post 208 located inside the housing 204. The second bevel gear 209 meshes with the second bevel gear 210. On the surface of the connecting tube 202, a first bevel gear 212 is fixedly connected to one end of the connecting post 211 located inside the connecting tube 202. A fixing sleeve 400 is connected to the surface of the connecting tube 202 at a position corresponding to the first bevel gear 212. A connecting rod 405 is rotatably connected to the inner cavity of the fixing sleeve 400. One end of the connecting rod 405 extends into the interior of the connecting tube 202 and is fixedly connected to a first bevel gear 404. The first bevel gear 404 meshes with the surface of the first bevel gear 212. A fixing member for fixing the connecting rod 405 is provided on the surface of the fixing sleeve 400. A handwheel 402 is fixedly connected to the other end of the connecting rod 405. By adjusting the components, rotating the handwheel 402 causes the connecting rod 405 to rotate. The first bevel gear 404 at one end of the 05 meshes with the first bevel gear 212 fixedly connected to one end of the connecting column 211 located in the inner cavity of the connecting pipe 202, causing the connecting column 211 to rotate. The second bevel gear 210, which extends from the bottom of the connecting column 211 to one end of the inner cavity of the housing 204, also rotates. It meshes with the second bevel gear 209 fixedly connected to the rotating column 208 at one end of each blade 205, thereby driving the blade 205 to rotate around the rotating column 208, realizing the adjustment of the tilt angle of the blade 205, thus achieving different stirring effects. This allows the operator to flexibly adjust the angle of the blade 205 according to different reaction requirements to achieve the best stirring effect and shear force, thereby refining the size of the crystals and making the crystal distribution more uniform.

A displacement connection assembly is provided at the bottom of the fixed disk 201 for moving the connecting pipe 202 upward, thereby driving the blade 205 to move upward. Through the configuration of the drive assembly, the transmission column 200 and the fixed disk 201 provide rotational power to the connecting pipe 202 and the blade 205, enabling the blade 205 to rotate stably and continuously, ensuring the stirring effect on the material and promoting the reaction.

[0034] Furthermore, the fixing component includes a fixing bolt 401 threaded to the top of the fixing sleeve 400. One end of the fixing bolt 401 is threaded through the fixing sleeve 400 and abuts against the surface of the connecting rod 405. Through the setting of the fixing component, the fixing bolt 401 with threaded connection has a simple and reliable structure, which can firmly fix the connecting rod 405 in the required position, ensuring that the angle of the blade 205 after adjustment remains stable and avoiding changes in angle due to vibration and other factors during the reaction process, thus affecting the stirring effect.

[0035] Preferably, a scale line 403 is provided on the end surface of the fixed sleeve 400 and on the outer circular surface of the connecting rod 405, and a pointer 406 is provided on the surface of the connecting rod 405 for pointing to the scale line 403.

[0036] It is worth noting that the displacement connection assembly includes a fixed column 304 fixedly connected to the center of the bottom of the fixed disk 201. The top of the connecting pipe 202 is provided with a fixed groove 306 corresponding to the fixed column 304. The fixed column 304 is inserted into the inner cavity of the fixed groove 306. The inner cavity of the fixed groove 306 is provided with a limiting member for limiting the fixed column 304. One side surface of the connecting column 211 is provided with several sets of threaded holes 300 arranged linearly from bottom to top and at equal intervals. The neck of the connecting pipe 202 is connected to a connecting sleeve 302. A first bolt 303 is inserted into the inner cavity of the connecting sleeve 302. One end of the first bolt 303 passes through the connecting sleeve 302 and is threaded into the inner cavity of one set of threaded holes 300. Through the setting of the displacement connection assembly, the position of the connecting pipe 202 and the blade 205 in the vertical direction can be adjusted, so that the blade 205 can stir the material at different heights to meet the stirring requirements of materials at different liquid levels.

[0037] Furthermore, the limiting component includes limiting grooves 305 respectively opened on both sides of the fixing groove 306. The inner cavities of the two sets of limiting grooves 305 are slidably connected to limiting strips 301 respectively. The two sets of limiting strips 301 are respectively fixedly connected to the corresponding side surfaces of the fixing column 304. By setting the limiting component, the up and down movement of the fixing column 304 in the fixing groove 306 can be stably limited, ensuring that the connecting pipe 202 and the blade 205 do not deviate or shake during the up and down movement, improving the accuracy and stability of the position adjustment. At the same time, it increases the contact surface between the fixing column 304 and the fixing groove 306, preventing the connecting column 211 from slipping, and reducing the stress on the first bolt 303.

[0038] Furthermore, the surface fixing sleeve 400 of the connecting pipe 202 near the nucleating agent production reactor 100 is provided with a limiting plate 203. The limiting plate 203 can prevent the connecting pipe 202 from sinking into the nucleating agent production reactor 100.

[0039] Preferably, a number of sets of foot pedals 104 are fixedly connected to one side of the nucleating agent production reactor 100, arranged equidistantly from bottom to top. Through the setting of the foot pedals 104, the foot pedals 104 on one side of the nucleating agent production reactor 100 provide operators with a convenient climbing and operating platform, which facilitates their operation, inspection and maintenance of the equipment on the top of the nucleating agent production reactor 100, thereby improving work efficiency and operational safety.

[0040] It is worth noting that the discharge end of the discharge pipe 108 is connected to a valve 107. Through the setting of the valve 107, the valve 107 at the discharge end of the discharge pipe 108 can conveniently control the discharge of materials. The valve 107 can be flexibly opened or closed according to the reaction progress and needs to realize the quantitative or continuous discharge of materials, which facilitates the control and management of the production process.

[0041] Working principle;

[0042] The nucleating agent is injected into the nucleating agent production reactor 100 through the feed pipe 101. Then, the drive motor 103 starts, and its output end drives the transmission column 200 to rotate. The fixed plate 201 at the bottom of the transmission column 200 also rotates. The fixed column 304 at the center of the bottom of the fixed plate 201 is inserted into the corresponding fixed groove 306 at the top of the connecting pipe 202. At the same time, the neck of the connecting pipe 202 is fixed to the connecting column 211 by the first bolt 303. The connecting pipe 202 will rotate together with the fixed plate 201. The rotation of the connecting pipe 202 drives the shell 204, which extends to the inner cavity of the nucleating agent production reactor 100 and is fixedly connected, to rotate. Several sets of blades 205 on the outer surface of the shell 204 also rotate, thereby stirring the material in the nucleating agent production reactor 100, promoting the full mixing of the material, and ensuring that the reaction can proceed smoothly.

[0043] Furthermore, in order to adapt to different reaction stages and the stirring requirements of different materials, the tilt angle of the blade 205 can be changed by using the adjustment component. During operation, the handwheel 402 connected to the surface of the fixed sleeve 400 is rotated. The handwheel 402 drives the connecting rod 405 to rotate. The first bevel gear 404 at one end of the connecting rod 405 meshes with the first bevel gear 212 fixedly connected to one end of the connecting column 211 located in the inner cavity of the connecting tube 202, so that the connecting column 211 rotates. The second bevel gear 210, which extends from the bottom of the connecting column 211 to one end of the inner cavity of the housing 204, also rotates. It meshes with the second bevel gear 209 fixedly connected to the rotating column 208 at one end of each blade 205, thereby driving the blade 205 to rotate around the rotating column 208, realizing the adjustment of the tilt angle of the blade 205, so as to achieve different stirring effects. Then, the fixing bolt 401 is tightened to fix the connecting rod 405.

[0044] At the same time, the first bolt 303 is removed and the connecting pipe 202 is lifted upward by the limiting plate 203, and the first bolt 303 is used to pass through the connecting sleeve 302 and connect to the threaded hole 300 at the corresponding position, thereby raising the position of the blade 205 in the nucleating agent production reactor 100.

[0045] After the reaction is completed, by opening the valve 107 connected to the discharge end of the discharge pipe 108, the reacted material is discharged from the nucleating agent production reactor 100 under the action of gravity along the discharge pipe 108. The valve 107 can be opened and closed as needed to precisely control the discharge process.
