Description
Technical Field
[0001] This utility model belongs to the technical field of synthetic rubber reactors, specifically relating to a rapid cooling system for synthetic rubber reactors. Background Technology
[0002] In the industrial production of synthetic rubber, the reactor, as the core reaction vessel, directly determines key performance indicators such as molecular weight distribution and crosslinking degree of the rubber product through precise control of its internal reaction temperature. Synthetic rubber polymerization reactions are mostly strongly exothermic. If the heat of reaction cannot be removed in a timely and efficient manner during the reaction, it will not only lead to a continuous increase in the reaction system temperature, causing localized overheating and exacerbating side reactions, but may also damage the stability of the polymerization reaction, resulting in fluctuations in product quality. Currently, jacketed cooling is widely used in small and medium-sized reactors. Due to the high viscosity of synthetic rubber reaction systems, some rubber materials tend to adhere to the inner wall of the jacket during the reaction process, forming a thick adhesion layer. This adhesion layer reduces the heat transfer efficiency between the jacket and the reaction system, resulting in a gradual decrease in the cooling rate, which cannot meet the production requirements for rapid cooling. Therefore, a rapid cooling system for synthetic rubber reactors is proposed. Utility Model Content

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1
[0015] Reference Figure 1-5 This is the first embodiment of the present invention. This embodiment provides a rapid cooling system for a synthetic rubber reactor, including a reactor 1 and a reactor cover 4 bolted to the top surface of the reactor 1. The reactor 1 is equipped with a cooling mechanism 2 and a stirring mechanism 3. The cooling mechanism 2 includes a cooling section and a cleaning section. The cooling section includes a cooling sleeve 21, the outer wall of which is fixedly connected to the inner side of the reactor 1.

An impeller 29 is rotatably mounted on the inner side of the cooling sleeve 21. A through groove is opened on the outer wall of the cooling sleeve 21, and two rotating frames 213 are slidably mounted on the inner wall of the through groove. The outer walls of the two rotating frames 213 are fixedly connected to the outer wall of the impeller 29. The inner side of the rotating frames 213 is fixedly connected to the outer wall of the scraper 23. Two sets of springs 217 and two sets of dampers 218 are fixedly mounted on the outer wall of the scraper 23. Two movable plates 215 are fixedly installed on the outer wall of the device 218. Two fixed frames 222 are fixedly installed on the outer wall of the two movable plates 215. Two rotating rods 221 are rotatably installed on the inner side of the two fixed frames 222 through two sets of bearing seats. Two cleaning plates 216 are fixedly installed on the outer wall of the two rotating rods 221. The outer wall of the two cleaning plates 216 is in contact with the outer wall of the scraper 23. Two torsion springs 220 are fixedly installed on the outer wall of the two cleaning plates 216. The top surface of the two torsion springs 220 is fixedly connected to the inner side of the two fixed frames 222.
[0016] The outer wall of the cooling sleeve 21 can be cleaned by two scrapers 23, which can prevent rubber from sticking to the outer wall of the cooling sleeve 21 during cooling and thus avoid affecting the cooling effect.
[0017] Furthermore, two movable frames 212 are slidably provided through the outer walls of the two rotating frames 213, extending to the inner side of the two rotating frames 213. Two inclined blocks 219 are fixedly provided on the inner side of the two movable frames 212, and two extrusion blocks 214 are fixedly provided on the outer walls of the two movable plates 215. The outer walls of the two extrusion blocks 214 are in contact with the inclined surfaces of the two inclined blocks 219, and multiple extrusion rods 22 are fixedly provided on the inner side of the reactor 1.
[0018] The two sets of cleaning plates 216 can clean the outer walls of the two scrapers 23, preventing excessive rubber from adhering to the surface of the two scrapers 23 when cleaning the outer wall of the cooling sleeve 21, thus affecting the cleaning effect.
[0019] Furthermore, a support plate 25 is fixedly installed on the outer wall of the reactor 1, and a condenser 24 is fixedly installed on the top surface of the support plate 25. A conveying pipe 26 is fixedly installed through the liquid inlet end of the condenser 24. The outer wall of the conveying pipe 26 passes through the outer wall of the reactor 1 and the outer wall of the cooling sleeve 21 and extends to the inner side of the cooling sleeve 21. A circulation pump 27 is fixedly installed on the top surface of the support plate 25. The outer wall of the circulation pump 27 is fixedly connected through the liquid inlet end to the outer wall of the condenser 24. A connecting pipe 28 is fixedly installed through the liquid outlet end of the circulation pump 27. The outer wall of the connecting pipe 28 passes through the outer wall of the reactor 1 and the outer wall of the cooling sleeve 21 and extends to the inner side of the cooling sleeve 21. A sealing ring 210 is fixedly installed on the outer wall of the impeller 29. The outer wall of the sealing ring 210 is slidably connected to the inner wall of the through groove. A guide rail 211 is fixedly installed on the inner side of the cooling sleeve 21. The outer wall of the guide rail 211 is slidably connected to the inner side of the impeller 29.
[0020] The condenser 24 can cool the cooling medium inside the cooling jacket 21 as it flows, and the circulating pump 27 can make the cooling medium inside the cooling jacket 21 flow.
[0021] When cooling the interior of the reactor 1 is required during operation, the circulating pump 27 and condenser 24 are turned on. After the circulating pump 27 and condenser 24 are turned on, the cooling medium inside the cooling jacket 21 flows, and during this flow, it cools the interior of the reactor 1. After the cooling medium enters the cooling jacket 21, it impacts the impeller 29, causing the impeller 29 to rotate. The rotation of the impeller 29 drives the two rotating frames 213 and the two scrapers 23 to rotate. The two scrapers 23, during their rotation, scrape the outer wall of the cooling jacket 21. During cleaning, the two rotating frames 213 can drive the two movable frames 212 to rotate synchronously. When the two movable frames 212 come into contact with the extrusion rod 22, they can extrude force. When the two movable frames 212 extrude force, they can drive the two sets of inclined blocks 219 to move synchronously. When the two sets of inclined blocks 219 move, they can extrude force on the two sets of extrusion blocks 214. When the two sets of extrusion blocks 215 are extruded, they can cause the two sets of movable plates 215 to move. When the two sets of movable plates 215 move, they can cause the two sets of cleaning plates 216 to move on the outer wall of the two scrapers 23 through the two sets of torsion springs 220, thereby cleaning the outer wall of the two scrapers 23.

A discharge pipe 36 is fixedly installed through the outer wall of the reactor 1 and extends to the inner side of the reactor 1. A second valve is fixedly installed through the outer wall of the discharge pipe 36.
[0023] Specifically, the material inside the outer wall of the reactor 1 can be stirred by rotating the stirring rod 35, and the temperature inside the reactor 1 can be measured by the thermometer 34.
[0024] In use, the material can be fed into the reactor 1 through the feed pipe 31. When it is necessary to stir the material inside the reactor 1, the servo motor 33 is turned on. When the output end of the servo motor 33 rotates, it can drive the stirring rod 35 to rotate. When the stirring rod 35 rotates, it can stir the material inside the outer wall of the reactor 1. Then, the material inside the reactor 1 can be discharged through the discharge pipe 36. The temperature inside the reactor 1 can be measured through the thermometer 34.
