[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 As shown, a PVC polymerization reactor includes a mounting frame 1. The mounting frame 1 is provided with an adjustment component 2. The adjustment component 2 includes an adjustment block 201. Two adjustment blocks 201 are slidably connected to the mounting frame 1. An installation shaft 202 is rotatably connected to the adjustment block 201. An installation block 207 is fixedly connected to the installation shaft 202. An installation sleeve 208 is installed on the installation block 207. A reactor body 5 is fixedly connected between the two installation sleeves 208. A worm gear 203 is fixedly connected to one of the installation shafts 202. A worm 204 meshes with the worm gear 203. The worm 204 is rotatably connected to the adjustment block 202.

[0024] As a technical optimization of this utility model, a first lead screw 209 is rotatably connected to the mounting frame 1. One of the adjusting blocks 201 is threadedly connected to the first lead screw 209. The output shaft of the motor rotates, driving the first lead screw 209 to rotate. When the first lead screw 209 rotates, the threaded adjustment block 201 slides on the mounting frame 1, and the other adjusting block 201 slides with the guide shaft 206. At the same time, the height of the reactor body 5 can be adjusted when the adjusting block 201 slides. After rotation, it is convenient to adjust the height according to maintenance needs, making maintenance more convenient and improving maintenance efficiency. A guide shaft 206 is fixedly connected to the mounting frame 1. The setting of the guide shaft 206 makes the sliding of the adjusting block 201 more stable. The other adjusting block 201 is slidably connected to the guide shaft 206. A first driving component 205 is installed on one of the adjusting blocks 201. The worm gear 204 is driven by the first driving component 205. A second driving component 210 is installed on the mounting frame 1. The first lead screw 209 is driven by the second driving component 210.

[0025] As a technical optimization of this utility model, the mounting frame 1 is provided with a fixing component 3, the fixing component 3 including a sliding frame 301, the sliding frame 301 is slidably connected to the mounting frame 1, and two fixing blocks 302 are fixedly connected to the sliding frame 301. When the reactor body 5 is in a vertical state, it is fixed by the fixing blocks 302, which improves the stability of the reactor body 5 during operation. The fixing blocks 302 abut against the reactor body 5. A guide plate 303 is fixedly connected to the mounting frame 1, and the sliding frame 301 and... The guide plate 303 is slidably connected, and an iron block 304 is fixedly connected to the guide plate 303. A magnetic block 305 is fixedly connected to the slide frame 301. When the magnetic block 305 moves to the iron block 304, the magnetic block 305 will attract the iron block 304. At this time, the slide frame 301 will not slide, and the fixing block 302 will not affect the rotation of the reactor body 5. A second lead screw 306 is rotatably connected to the slide frame 301. The mounting bracket 1 is provided with a threaded hole 307, and the second lead screw 306 is threadedly engaged with the threaded hole 307.

[0026] As a technical optimization of this utility model, the reaction vessel body 5 is provided with a stirring assembly 4, which includes a stirring shaft 401. The stirring shaft 401 is rotatably connected to the reaction vessel body 5. The stirring shaft 401 is equipped with stirring blades 403 and a frame stirrer 404. During rotation, the stirring blades 403 can generate a strong radial flow, which can quickly disperse the raw materials in the center of the reaction vessel to the periphery and promote the mixing of the raw materials in the horizontal direction. The frame stirrer 404 focuses more on stirring the raw materials at the bottom of the reaction vessel and near the inner wall. It can effectively prevent the raw materials from settling in these areas and promote the circulation of the raw materials in the vertical direction. The two work together to form a complex and efficient stirring flow field, so that the various raw materials in the reaction vessel body 5 can be fully and evenly mixed. A third driving component 402 is installed on the reaction vessel body 5, and the stirring shaft 401 is driven by the third driving component 402.

[0027] When this utility model is in use, and maintenance of the reactor body 5 is required, the second lead screw 306 is first rotated by the rotating rod 308 sliding on the second lead screw 306. When the second lead screw 306 no longer engages with the threaded hole 307, the sliding frame 301 continues to slide along the guide plate 303. The guide plate 303 makes the sliding frame 301 slide more smoothly, and at the same time, it causes the fixing block 302 to no longer contact the reactor body 5. When the magnetic block 305 moves to the iron block 304, the magnetic block 305 will attract the iron block 304. At this time, the sliding frame 301 will not slide, and the fixing block 302 will not affect the rotation of the reactor body 5. When the reactor body 5 is in a vertical state, it is fixed by the fixing block 302, which improves the stability of the reactor body 5. The stability of the reactor body 5 during operation can be ensured by activating the first driving component 205 (preferably a motor). The motor's output shaft rotates, driving the worm gear 204 to rotate. The worm gear 204 drives the worm wheel 203 to rotate, which in turn drives the mounting shaft 202. The mounting shaft 202, through the mounting block 207 and mounting sleeve 208, drives the reactor body 5 to rotate. This rotation of the reactor body 5 changes its angle, allowing maintenance personnel to easily access all corners and components inside the reactor. Furthermore, when adjusting the height of the reactor body 5, the second driving component 210 (preferably a motor) can be activated. The motor's output shaft rotates, driving the first lead screw 209. When the first lead screw 209 rotates, the threaded drive adjusting block 201 slides on the mounting bracket 1, and the other adjusting block 201 slides with the guide shaft 206. The guide shaft 206 makes the sliding of the adjusting block 201 more stable. At the same time, the height of the reactor body 5 can be adjusted when the adjusting block 201 slides. After rotation, it is convenient to adjust the height according to maintenance needs, making maintenance more convenient and improving maintenance efficiency. When stirring the raw materials, the third drive component 402 (preferably a motor) is started. When the output shaft of the motor rotates, it drives the stirring shaft 401 to rotate. When the stirring shaft 401 rotates, it drives the stirring fan blades 403 and the frame agitator 404 to rotate. During rotation, blade 403 generates a strong radial flow, rapidly dispersing the raw materials from the center of the reactor to the periphery and promoting horizontal mixing. Meanwhile, frame agitator 404 focuses on stirring the raw materials at the bottom and near the inner wall of the reactor, effectively preventing sedimentation in these areas and promoting vertical circulation. The two work together to form a complex and efficient stirring flow field, ensuring thorough and uniform mixing of all raw materials within the reactor body 5. This thorough stirring creates favorable conditions for the PVC polymerization reaction, allowing for more frequent contact and reaction between different raw material molecules, thus guaranteeing the smooth progress of the polymerization reaction and improving the quality stability and production efficiency of PVC products.
