Description

Technical Field

[0001] This utility model relates to the field of plexiglass particle production technology, specifically a polymerization reactor for producing plexiglass particles. Background Technology

[0002] Polymethyl methacrylate (PMMA, also known as acrylic glass) is an important light-transmitting material widely used in automobiles, construction, optics, medical and other fields. It is usually copolymerized from methyl methacrylate (MMA) and a small amount of acrylate monomers. Common polymerization processes include suspension, solution and bulk polymerization, among which stirred tank reactors are the most widely used.

[0003] Application number CN202323102681.6 discloses a high-efficiency particle dispersion reactor, including a bottom plate, a rotating mechanism, a feeding mechanism, and a dispersing mechanism. The rotating mechanism is installed above the bottom plate, the feeding mechanism is installed above the rotating mechanism, and the dispersing mechanism is installed inside the rotating mechanism. The rotating mechanism also includes a first motor installed on the upper surface of the bottom plate. In the process of dispersing materials, the feeding mechanism performs initial dispersion of the materials during feeding, and then the rotating mechanism further disperses the materials and drives the materials to rotate, avoiding the problem of uneven dispersion caused by material settling. At the same time, the dispersing mechanism performs stirring and dispersing operations on the materials, performing multiple dispersion operations to improve the dispersion efficiency of the materials and facilitate their use. However, the drawback is that the device does not integrate a shaking function module in actual operation, and only relies on rotation and stirring actions to achieve material mixing. When dealing with high-viscosity particulate materials or mixed systems with large density differences, the lack of shaking can easily lead to local accumulation of materials at the bottom of the reactor, making it impossible to form a full-range convection circulation. This makes it difficult to achieve sufficient contact and fusion of internal materials, and also makes it impossible to further shorten the mixing time and improve the overall mixing efficiency. Its applicability is limited in scenarios where high mixing uniformity is required. Utility Model Content

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.

[0017] Please see Figures 1-4 As shown, this utility model is a polymerization reactor for producing plexiglass particles, including a support assembly 1, a reactor assembly 3 mounted on the top of the support assembly 1 via a shaking assembly 2, and an anti-wall-sticking mixing assembly 4 fixedly installed inside the reactor assembly 3. The shaking assembly 2 includes a shaking machine 201. A transmission box 202 is fixedly installed on the top of the shaking machine 201. A rotating rod 203 is fixedly installed on the inner side of the transmission box 202. The rotating rod 203 is limited and installed inside a limiting groove 103 on one side, and the end of the rotating rod 203 is limited and installed inside a fixing ring 204. After the shaking machine 201 is started, the rotating rod 203 is driven to rotate through the transmission box 202. The rotating rod 203 is limited and moves within the limiting groove 103 on one side. At the same time, its end drives the reaction vessel 301 to move through the fixing ring 204. The limiting rod in the fixing ring 204 on the other side moves synchronously within the limiting groove 103 on the other side, thereby realizing the stable shaking of the reaction vessel assembly 3 and promoting material mixing.

[0018] By installing a shaking component 2 on the device, the reactor can be shaken during mixing, making the mixing process more uniform and efficient.

[0019] The bracket assembly 1 includes a bracket frame 101, with a fixed suction cup 102 fixedly installed at the bottom diagonally of the bracket frame 101, and a limit groove frame 103 fixedly installed at the middle position of the two sides of the top of the bracket frame 101.

[0020] The reaction vessel 301 is correspondingly installed in the middle of the support frame 101. The support frame 101 provides the installation foundation for the entire equipment. The fixed suction cups 102 at the bottom diagonally enhance the stability of the equipment. The limiting groove frame 103 at the middle position of the top two sides provides the limiting installation space for the rotating rod 203 and the limiting rod of the shaking component 2, ensuring the stable operation of the shaking component 2.

[0021] The reactor assembly 3 includes a reaction vessel 301. Fixing rings 204 are fixedly installed on both outer walls of the reaction vessel 301, and an opening and closing sealing cover 302 is rotatably installed on the rear top of the reaction vessel 301. An assembly slot 303 is opened on the outer wall of the opening and closing sealing cover 302. The interior of the assembly slot 303 is limited and installed on the top of the reaction vessel 301 by a fixing locking member 304. A limit rod is provided inside the fixing ring 204 on the other side, and the limit rod is limited and installed inside the limit slot frame 103 on the measuring side.

[0022] The fixing locking component 304 includes a positioning rod 3041. The bottom of the positioning rod 3041 is rotatably mounted on the top outer wall of the reaction vessel 301 via a limiting shaft 3042, and the positioning rod 3041 is limited and installed inside the assembly slot 303. At the same time, a fastening nut 3043 is installed at the top of the positioning rod 3041. The reaction vessel 301 serves as a container for material polymerization reaction. The opening and closing sealing cover 302 on the rear top side of the reaction vessel 301 can realize the opening and closing of the reaction vessel 301. The assembly slot 303 cooperates with the fixing locking component 304. Through the limiting of the positioning rod 3041 in the assembly slot 303, combined with the rotational installation of the limiting shaft 3042 and the limiting fixation of the fastening nut 3043, it is ensured that the opening and closing sealing cover 302 is tightly closed on the top of the reaction vessel 301, ensuring a sealed reaction environment.

[0023] The anti-wall-hanging mixing assembly 4 includes a rotary motor 401, which is fixedly mounted on the top of the opening and closing sealing cover 302 by a bracket. A mixing rod 402 is fixedly mounted on the bottom of the rotary motor 401, and a mounting base 403 is fixedly mounted on the bottom of the mixing rod 402. A scraper stirring blade 404 is fixedly mounted on the outer wall of the mounting base 403, and the scraper stirring blade 404 is attached to the inner wall of the reaction vessel 301.

[0024] The polymerization reactor for producing acrylic granules is stably supported by a support assembly 1. A shaking assembly 2 drives the reactor assembly 3 to shake, while an anti-wall mixing assembly 4 stirs the material inside the reaction vessel 301, preventing material from adhering to the walls. This ultimately achieves the efficient polymerization reaction required for acrylic granule production. The support frame 101 provides the installation foundation for the entire equipment. Diagonally positioned suction cups 102 at the bottom enhance stability. Limiting slots 103 at the top center provide space for the rotating rod 203 and limiting rod of the shaking assembly 2, ensuring stable operation. After the shaking mechanism 201 starts, the transmission box 202 drives the rotating rod 203 to rotate. The rotating rod 203 moves within one limiting slot 103, while its end moves the reaction vessel 301 via a fixing ring 204. Simultaneously, the limiting rod within the fixing ring 204 moves within the limiting slot 103 on the other side, thus achieving stable shaking of the reactor assembly 3 and promoting material flow. The mixing and reaction vessel 301 serves as a container for the polymerization reaction of materials. The top rear side of the top opening and closing sealing cover 302 enables the opening and closing of the reaction vessel 301. The assembly slot 303 cooperates with the fixing lock 304. The positioning rod 3041 limits the position within the assembly slot 303. Combined with the rotational installation of the limiting shaft 3042 and the limiting fixation of the fastening nut 3043, it is ensured that the opening and closing sealing cover 302 is tightly closed on the top of the reaction vessel 301, ensuring a sealed reaction environment. After the rotary motor 401 is started, it drives the mixing rod 402 to rotate. The mounting base 403 at the bottom of the mixing rod 402 rotates synchronously with it, thereby driving the scraper stirring blade 404 on the outer wall to rotate. The scraper stirring blade 404 adheres to the inner wall of the reaction vessel 301, scraping off the material on the vessel wall while stirring the material, preventing the material from sticking to the wall and ensuring that the material is fully mixed and reacted.In the workflow, the raw materials required for producing plexiglass particles are added to the reaction vessel 301. The opening and closing sealing cover 302 is rotated to close the top of the reaction vessel 301. The positioning rod 3041 is rotated into the assembly slot 303 via the limiting shaft 3042. The fastening nut 3043 is installed on the top of the positioning rod 3041 and tightened to limit and fix the opening and closing sealing cover 302, ensuring the reaction vessel 301 is sealed. The shaking mechanism 201 of the shaking assembly 2 is started. The shaking mechanism 201 drives the rotating rod 203 to rotate via the transmission box 202. The rotating rod 203 moves within the limiting slot frame 103 on one side, and its end drives the reaction vessel 301 to move via the fixing ring 204. The limiting rod in the fixing ring 204 on the other side moves synchronously within the limiting slot frame 103 on the other side, causing the reaction vessel assembly 3 to start shaking stably, initially promoting material mixing. The rotating motor 401 of the anti-wall-hanging mixing assembly 4 is started. The rotating motor 401 drives the mixing rod 402 to rotate. The mixing rod 402 drives the mounting base 403 and the scraper stirring blade 404 to rotate. The scraper stirring blade 404 rotates against the inner wall of the reaction tank 301 to stir the material and scrape off the material from the tank wall to prevent it from sticking. At this time, the shaking component 2 continues to run, cooperating with the stirring action to achieve efficient mixing of the material. Under the dual action of shaking and stirring, the raw materials in the reaction tank 301 are fully mixed and undergo polymerization reaction. During this period, the sealing effect of the opening and closing sealing cover 302 ensures the environmental conditions required for the reaction. The support frame 101 and the fixed suction cup 102 of the support component 1 ensure the overall stability of the equipment and provide a stable operating environment for the polymerization reaction. After the polymerization reaction is completed, first turn off the rotary motor 401 and the shaking machine 201, then unscrew the fastening nut 3043, rotate the positioning rod 3041 out of the assembly slot 303 through the limiting shaft rod 3042, open the opening and closing sealing cover 302, and take out the organic glass particles and related products generated in the reaction tank 301 to complete one production process.
