[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Figure 1 - Figure 5 As shown, the utility model provides a high-efficiency dimethylaminosulfonyl synthesis reactor, comprising a lower kettle body 1 and an upper kettle body 2, the upper kettle body 2 is arranged on the outer top of the lower kettle body 1, and a stirring mechanism 3 is provided at the bottom of the upper kettle body 2. A limiting hole 4 is provided on one side of the lower kettle body 1, and a fixed shell 5 is fixedly connected to one side of the upper kettle body 2. A screw 6 is rotatably connected in the fixed shell 5, and a movable plate 7 is sleeved on the outer surface of the screw 6. A limiting rod 8 is fixedly connected to one side of the movable plate 7, and one end of the limiting rod 8 movably passes through the fixed shell 5 and the upper kettle body 2 and extends into the limiting hole 4. A limiting groove 9 is provided on the inner top of the fixed shell 5, and a limiting block 10 is slidably connected in the limiting groove 9. The bottom of the limiting block 10 is fixedly connected to the movable plate 7.

[0024] The effect achieved by the entire embodiment 1 is that, by rotating the screw 6, the limit block 10 limits the movable plate 7, so that the screw 6 rotates to drive the movable plate 7 to move, and the movable plate 7 drives the limit block 10 to slide in the limit groove 9, so that the movable plate 7 drives the limit rod 8 to move and separate from the limit hole 4, thereby releasing the restriction on the upper kettle body 2, making it convenient to remove the upper kettle body 2 and to clean the inner wall of the lower kettle body 1, solving the problem that the existing reactor is inconvenient to clean and maintain the inner wall of the reactor during use, and the material adhering to the inner wall of the reactor for a long time will cause serious corrosion, thereby greatly shortening the service life of the reactor.

[0025] Example 2: Figure 1 - Figure 5 As shown, the stirring mechanism 3 includes an empty slot 301, which is opened inside the upper kettle body 2, and a first rotating shaft 302 is rotatably connected in the empty slot 301. Two second rotating shafts 303 are rotatably connected in the empty slot 301. The outer surface of the first rotating shaft 302 is fixedly sleeved with a first gear 304, and the outer surfaces of the two second rotating shafts 303 are fixedly sleeved with two second gears 305. The first gear 304 is meshed with the second gear 305. The bottom end of the second rotating shaft 303 is movable through the empty slot 301 and extends to the outside of the upper kettle body 2. The outer surfaces of the two second rotating shafts 303 are fixedly connected with a plurality of stirring plates 306. A driving motor 307 is fixedly installed on the top of the upper kettle body 2, and the output end of the driving motor 307 movably passes through the upper kettle body 2 and extends into the empty groove 301. The output end of the driving motor 307 is fixedly connected to the first rotating shaft 302. A sealing groove 11 is provided on the top of the lower kettle body 1, and a sealing block 12 is fixedly connected to the inner top of the upper kettle body 2. The top of the upper kettle body 2 is fixedly connected to a feed pipe 13, and the bottom of the lower kettle body 1 is fixedly connected to a discharge pipe 14. Valves 15 are installed on both the feed pipe 13 and the discharge pipe 14. The smooth end of the screw 6 movably passes through the fixed shell 5, and the smooth end of the screw 6 is fixedly installed with a rotating handle 16.

[0026] The effect achieved by the entire embodiment 2 is that, through the provided stirring mechanism 3, the drive motor 307 is started, so that the first rotating shaft 302 drives the first gear 304 to rotate. Since the first gear 304 is meshed with the second gear 305, the two second gears 305 drive the two second rotating shafts 303 to rotate, thereby driving the plurality of stirring plates 306 to rotate, which is convenient for mixing the reactants in the lower kettle body 1, effectively improving the reaction effect of the reactor. The outer surfaces of the two second rotating shafts 303 are fixedly connected with a plurality of stirring plates 306, which effectively improves the reaction efficiency of the reactor. Then, through the provided sealing groove 11 and the sealing block 12, the sealing groove 11 and the sealing block 12 match, and the sealing block 12 is located in the sealing groove 11, which improves the sealing performance when the upper kettle body 2 and the lower kettle body 1 are connected. Then, by opening the valve 15 on the feed pipe 13, the reactants are easily put into the lower kettle body 1, and the valve 15 on the discharge pipe 14 is opened to facilitate the discharge of the reactants after the reaction through the discharge pipe 14. Then, by the provided rotating handle 16, the screw 6 is easily rotated.

[0027] Working principle: When in use, open the valve 15 on the feed pipe 13, and feed the reactants required for the production of dimethylaminosulfonyl into the lower kettle body 1 through the feed pipe 13. Then close the valve 15 on the feed pipe 13, and then start the drive motor 307, so that the first shaft 302 drives the first gear 304 to rotate. Since the first gear 304 is meshed with the second gear 305, the two second gears 305 drive the two second shafts 303 to rotate, thereby driving the plurality of stirring plates 306 to rotate, mixing the reactants in the lower kettle body 1, effectively improving the reaction effect of the reactor. After the reaction is completed, the discharge pipe 14 can be opened. The valve 15 allows the reactants that have completed the reaction to be discharged through the discharge pipe 14. When the inner wall of the lower kettle body 1 needs to be cleaned, the handle 16 is turned to drive the screw 6 to rotate. Since the limit block 10 limits the movable plate 7, the screw 6 rotates to drive the movable plate 7 to move, and the movable plate 7 drives the limit block 10 to slide in the limit groove 9, so that the movable plate 7 drives the limit rod 8 to move and separate from the limit hole 4, thereby releasing the restriction on the upper kettle body 2. Then the upper kettle body 2 is removed and the inside of the lower kettle body 1 is cleaned. At the same time, it is also convenient to clean the inner wall of the upper kettle body 2 and the surface of the stirring plate 306, thereby improving the service life of the reactor.
