Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymerization reactor processing technology, and in particular to a polymerization reactor for low molecular weight ingredient production. Background Technology
[0002] Polymerization reactors for low molecular weight ingredients are commonly used in the chemical and materials industries. By precisely controlling conditions such as temperature, pressure, and stirring, they enable monomers to undergo polymerization reactions, effectively synthesizing low molecular weight polymers. These polymers are widely used in industries such as coatings, adhesives, and electronic materials, and are of great significance in promoting the improvement of product performance in related industries.
[0003] In practical applications, existing low-molecular-weight batching polymerization reactors, when used in conjunction with temperature control systems and high-efficiency stirring devices, can meet the basic requirements of polymerization reactors. However, the following problems still exist:
[0004] In the polymerization reaction system of low molecular weight ingredients, the viscosity of the material changes as the reaction proceeds. Due to the growth of polymer chains, the viscosity of the material gradually increases, which leads to a decrease in the stirring effect, resulting in uneven mixing of monomers, local overheating of the reaction, and affecting product quality. At the same time, the polymer will adhere to the inner wall of the polymerization reactor during the reaction, further affecting the reaction effect. Therefore, this application provides a polymerization reactor for the production of low molecular weight ingredients to meet the needs. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a polymerization reactor for low molecular weight ingredient production.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a polymerization reactor for low molecular weight ingredient production, comprising a tank body and a feed inlet disposed at the top of the tank body;
[0007] A stirring assembly is placed inside the inner cavity of a tank. The stirring assembly includes a transmission rod disposed at the top of the inner cavity of the tank, a sleeve disposed on the side of the transmission rod, a support plate fixedly connected to the outer surface of the transmission rod, the top of the sleeve fixedly connected to the inner wall of the tank, a support rod rotatably connected to the bottom of the sleeve, a first telescopic rod fixedly connected to the bottom of the support rod, and a first connecting rod fixedly connected to the side of the first telescopic rod.
[0008] A scraping assembly is placed at the bottom of the stirring assembly. The scraping assembly includes a third telescopic rod fixedly connected to the bottom of the support plate, and a second connecting rod is fixedly connected to the bottom of the third telescopic rod.
[0009] In a preferred embodiment, the inner wall of the sleeve is provided with a groove, and the inner cavity of the transmission rod is fixedly connected with a threaded rod.
[0010] The technical effect of adopting the above technical solution is that by setting the groove, the transmission rod can be made to move up and down reciprocatingly.
[0011] In a preferred embodiment, a limiting groove is formed on the side of the inner cavity of the transmission rod, and a threaded groove is formed on the top of the support rod. One end of the threaded rod extends into the inner cavity of the threaded groove, and one end of the threaded rod is rotatably connected to the inner cavity of the threaded groove.
[0012] The technical effect of adopting the above technical solution is that, through the cooperation of the support rod and the threaded groove, the transmission rod and the support rod can be stably transmitted, effectively improving the overall stability.
[0013] In a preferred embodiment, a second telescopic rod is fixedly connected to the top of the support plate, and a limit plate is provided at the end of the second telescopic rod away from the support plate.
[0014] The technical effect of adopting the above technical solution is that by setting a second telescopic rod, the movement distance of the transmission rod can be compensated, thus avoiding the displacement of the stirring rod located at one end of the first connecting rod.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] The top of the transmission rod is connected to the output end of the motor via a telescopic component. In use, the material is first fed into the inner cavity of the tank through the inlet. Then, the motor located at the top of the transmission rod is started. The motor's output rotates clockwise, causing the transmission rod to rotate clockwise, which in turn causes the transmission rod to reciprocate up and down. When the transmission rod moves downwards, it drives the first telescopic rod to move counterclockwise via the support rod, which in turn drives the stirring rod located at one end of the first connecting rod to mix the material. Similarly, when the transmission rod moves upwards, it drives the first telescopic rod to move clockwise via the support rod, effectively improving the mixing effect of the stirring rod. Simultaneously, the reciprocating rotation of the stirring rod improves mixing efficiency and prevents the material viscosity from increasing during subsequent reactions, which could affect the reaction results. A second connecting rod drives a scraper to scrape the inner wall of the tank, and a third telescopic rod compensates for the scraper's movement distance. Attached Figure Description

[0025] 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.
[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a polymerization reactor for low molecular weight ingredient production, comprising a tank 1 and a feed inlet 11 disposed on the top of the tank 1;
[0027] A stirring assembly 2 is placed inside the tank 1. The stirring assembly 2 includes a transmission rod 21 located at the top of the tank 1. A sleeve 22 is provided on the side of the transmission rod 21. A support plate 29 is fixedly connected to the outer surface of the transmission rod 21. The top of the sleeve 22 is fixedly connected to the inner wall of the tank 1. A support rod 26 is rotatably connected to the bottom of the sleeve 22. A first telescopic rod 28 is fixedly connected to the bottom of the support rod 26. A first connecting rod 211 is fixedly connected to the side of the first telescopic rod 28.
[0028] The scraping component 3 is located at the bottom of the stirring component 2. The scraping component 3 includes a third telescopic rod 31 fixedly connected to the bottom of the support plate 29. A second connecting rod 32 is fixedly connected to the bottom of the third telescopic rod 31. A groove 23 is provided on the inner wall of the sleeve 22. A threaded rod 25 is fixedly connected to the inner cavity of the transmission rod 21. A second telescopic rod 210 is fixedly connected to the top of the support plate 29. A limit plate 212 is provided at the end of the second telescopic rod 210 away from the support plate 29. The bottom of the first telescopic rod 28 is rotatably connected to the bottom of the inner cavity of the tank 1. The top of the transmission rod 21 is connected to the output end of the motor via a telescopic component. In use, the material is first fed into the inner cavity of the tank 1 through the feed inlet 11. Then, the motor located on the top of the transmission rod 21 is started. The output end of the motor rotates clockwise, thereby causing the transmission rod 21 to rotate clockwise along the inner cavity of the groove 23. By setting the groove 23, the transmission rod 21 can be made to move up and down reciprocally. When the transmission rod 21 moves downwards... When in motion, the limiting groove 24 and the support rod 26 cooperate to cause the support rod 26 to move counterclockwise, thereby driving the first telescopic rod 28 to move counterclockwise. When the first telescopic rod 28 moves counterclockwise, it can drive the stirring rod at one end of the first connecting rod 211 to mix the materials. Similarly, when the transmission rod 21 moves upward, it can drive the first telescopic rod 28 to move clockwise through the support rod 26, effectively improving the mixing effect of the stirring rod. At the same time, the reciprocating rotation of the stirring rod can improve the mixing efficiency and avoid the material viscosity from increasing in the subsequent reaction process, which would affect the reaction effect. The limiting plate 212 can cause the stirring rod to rotate. The second connecting rod 32 can drive the scraper 35 to scrape the inner wall of the tank 1. The third telescopic rod 31 can compensate for the movement distance of the scraper 35.
[0029] Furthermore, such as Figure 3 and Figure 4As shown: A slider 33 is fixedly connected to the top of the second connecting rod 32, and a groove 34 is provided at the bottom of the limiting plate 212. The top of the slider 33 extends into the inner cavity of the groove 34, and the top of the slider 33 is slidably connected to the inner cavity of the groove 34. A scraper 35 is fixedly connected to the bottom of the second connecting rod 32. Both sides of the scraper 35 are in contact with the inner wall of the tank 1. When the transmission rod 21 rotates clockwise, it can drive the third telescopic rod 31 to move clockwise through the support plate 29, thereby achieving the effect of driving the second connecting rod 32 to move through the third telescopic rod 31. When the second connecting rod 32 moves clockwise, the slider 33 and the groove 34 cooperate to cause the scraper 35 to scrape off the material attached to the inner wall of the tank 1, effectively improving the reaction effect. By setting the third telescopic rod 31, the movement distance of the transmission rod 21 can be compensated, and the position of the scraper 35 can be deviated during use, which would cause damage.
[0030] When the transmission rod 21 drives the support rod 26 to move, the position of the support rod 26 may slightly shift during the operation of the transmission rod 21 due to the different mixing speed requirements of the material each time, affecting the mixing effect. Figure 3 As shown: In this design, a limiting groove 24 is provided on the side of the inner cavity of the transmission rod 21, and a threaded groove 27 is provided on the top of the support rod 26. One end of the threaded rod 25 extends into the inner cavity of the threaded groove 27, and the threaded rod 25 is rotatably connected to the inner cavity of the threaded groove 27. Through the threaded rod 25, the transmission rod 21 and the support rod 26 can be stably connected. At the same time, when the transmission rod 21 rotates clockwise, the limiting groove 24 is provided to prevent the support rod 26 from disengaging from the inner cavity of the transmission rod 21, thereby effectively improving the operational stability.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
