Description

Technical Field

[0001] This utility model relates to the field of perfluorosulfonic acid resin modification reaction technology, specifically a perfluorosulfonic acid resin modification reaction device. Background Technology

[0002] Perfluorosulfonic acid resins (such as Nafion) are a class of high-performance polymers with a perfluorocarbon backbone and sulfonic acid groups (-SO3H) on the side chains. Due to their excellent chemical stability, thermal stability, and proton conductivity, they are widely used in fuel cells, catalysis, membrane separation, and other fields. However, their linear structure leads to problems such as insufficient mechanical strength, easy swelling under high humidity, and high methanol permeability. Therefore, it is necessary to optimize their performance through modification reactions.

[0003] In the heating process of liquid modification reaction of perfluorosulfonic acid resin, traditional heating methods are difficult to achieve efficient and uniform heating. The liquid at the bottom of the heating cylinder is not easy to fully replace with the surrounding liquid, which means that the liquid at the bottom cannot be fully heated during the modification reaction, affecting the uniformity and stability of the reaction. Moreover, traditional heating devices are difficult to promote uniform temperature distribution in the reaction system, which can easily lead to local overheating or temperature gradient problems. This not only reduces the quality of the product, but also affects the reaction rate. Utility Model Content

[0004] The purpose of this invention is to provide a perfluorosulfonic acid resin modification reaction device to solve the problem mentioned in the background art that in the heating process of the perfluorosulfonic acid resin liquid modification reaction, it is difficult to achieve efficient and uniform heating by traditional heating methods, and the liquid at the bottom of the heating cylinder is not easy to fully replace with the surrounding liquid, resulting in the bottom liquid not being fully heated during the modification reaction.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a perfluorosulfonic acid resin modification reaction device, comprising a reaction vessel, wherein a heating mechanism and a cleaning mechanism are provided inside the reaction vessel;

[0006] The heating mechanism includes a fixed plate fixedly connected to the top surface of the reaction vessel. A motor is fixedly connected to the bottom of the fixed plate. A rotating rod is fixedly connected to the output end of the motor via a coupling. Three flow guide shells are fixedly connected to the inner wall of the reaction vessel. Each of the three flow guide shells has four feed inlets on its outer wall and a discharge outlet at its bottom. The rotating rod rotates through the three flow guide shells. Three turntables are fixedly connected to the outer wall of the rotating rod. Guide vanes are fixedly connected to the bottom of each of the three turntables. The three guide vanes are located inside the three flow guide shells.

[0007] Preferably, the reaction vessel has a heating chamber inside, a heating wire is installed inside the heating chamber, a heating cylinder is fixedly connected to the inner wall of the reaction vessel, and the three flow guide shells are all located inside the heating cylinder.

[0008] Preferably, the cleaning mechanism includes a rotating sleeve that rotatably extends through the top of the reaction vessel, and the rotating sleeve is slidably connected to the outer wall of the rotating rod.

[0009] Preferably, a bevel gear one is fixedly connected to the outer wall of the rotating rod, and a bevel gear two is fixedly connected to the outer wall of the rotating sleeve.

[0010] Preferably, a fixing rod is fixedly connected to the top of the reaction vessel, and a bevel gear three is rotatably connected to the outer wall of the fixing rod. The bevel gear three meshes with bevel gear one and bevel gear two respectively.

[0011] Preferably, the outer wall of the rotating sleeve is fixedly connected to a plurality of connecting rods, and the outer wall of each of the plurality of connecting rods is fixedly connected to a scraper, and the plurality of scrapers are in contact with the inner wall of the heating cylinder.

[0013] Preferably, the discharge pipe is equipped with a valve, and the top of the discharge pipe extends into the interior of the heating cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model incorporates a heating mechanism. When the drive motor rotates the rotating rod, multiple guide vanes on the three rotating discs on the rod draw the perfluorosulfonic acid resin liquid from the bottom of the guide shell to its interior, where it is then flung out under centrifugal force. This causes the liquid at the bottom of the three guide shells to exchange with the surrounding liquid. Meanwhile, the liquid at the bottom of the entire heating cylinder is flung onto the inner wall of the heating cylinder by the rotating discs for further exchange. This improves the overall heating effect and efficiency when the heating wire heats the cylinder wall, preventing the perfluorosulfonic acid resin liquid at the bottom of the heating cylinder from being insufficiently heated during the modification reaction, thus ensuring the uniformity and stability of the reaction. Simultaneously, the device promotes uniform temperature distribution in the reaction system through continuous liquid circulation and heating, preventing localized overheating or temperature gradients, effectively improving product quality and reaction rate.

[0016] 2. This utility model is equipped with a cleaning mechanism. While stirring and exchanging heat in the liquid inside the heating cylinder, the rotating rod drives the rotating sleeve to rotate in the opposite direction through the transmission of bevel gear one, bevel gear two and bevel gear three. This causes the scrapers on multiple connecting rods to scrape and wash the inner wall of the heating cylinder, preventing the gel-like perfluorosulfonic acid resin liquid adhering to the heating cylinder from affecting the heating effect, and further improving the overall heating efficiency of the device. The feed pipe is used to add raw materials, while the discharge pipe and valve are used to discharge the liquid after the reaction. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5One embodiment of this utility model is a perfluorosulfonic acid resin modification reaction device, which includes a reaction tank 1, and a heating mechanism 2 and a cleaning mechanism 3 are provided inside the reaction tank 1.

[0026] The heating mechanism 2 includes a fixed plate 24 fixedly connected to the top surface of the reaction vessel 1. A motor 25 is fixedly connected to the bottom of the fixed plate 24. A rotating rod 26 is fixedly connected to the output end of the motor 25 via a coupling. Three flow guide shells 27 are fixedly connected to the inner wall of the reaction vessel 1. Each of the three flow guide shells 27 has four feed inlets 28 on its outer wall and a discharge outlet 29 at its bottom. The rotating rod 26 rotates through the three flow guide shells 27. Three turntables 291 are fixedly connected to the outer wall of the rotating rod 26. A guide rod 291 is fixedly connected to the bottom of each of the three turntables 291. The flow vane 292 and the three flow guide vanes 292 are respectively located inside the three flow guide shells 27. The interior of the reaction vessel 1 is provided with a heating chamber 21, and a heating wire 22 is provided inside the heating chamber 21. A heating cylinder 23 is fixedly connected to the inner wall of the reaction vessel 1. The three flow guide shells 27 are all located inside the heating cylinder 23. The cleaning mechanism 3 includes a rotating sleeve 31 that rotatably passes through the top of the reaction vessel 1. The rotating sleeve 31 is slidably connected to the outer wall of the rotating rod 26. A bevel gear 32 is fixedly connected to the outer wall of the rotating rod 26. A bevel gear 33 is fixedly connected to the outer wall of the rotating sleeve 31.

[0027] A fixed rod 34 is fixedly connected to the top of the reaction vessel 1. A bevel gear 35 is rotatably connected to the outer wall of the fixed rod 34. The bevel gear 35 meshes with bevel gear 1 32 and bevel gear 2 33 respectively. Several connecting rods 36 are fixedly connected to the outer wall of the rotating sleeve 31. Scrapers 37 are fixedly connected to the outer walls of the connecting rods 36. The scrapers 37 are in contact with the inner wall of the heating cylinder 23. A feed pipe 38 is connected to the top of the reaction vessel 1. A discharge pipe 39 is connected to the bottom of the reaction vessel 1. A valve 391 is installed on the discharge pipe 39. The top of the discharge pipe 39 extends into the interior of the heating cylinder 23.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A motor 25 is fixedly installed on the top of the reaction vessel 1. Multiple flow guide shells 27 are connected and fixedly installed at the bottom of the reaction vessel 1 by multiple mounting rods. A rotating rod 26 is rotatably installed on the inner wall of the multiple flow guide shells 27 while passing through the three flow guide shells 27. When the drive motor 25 drives the rotating rod 26 to rotate, it drives the three turntables 291 and multiple flow guide blades 292 to rotate inside the three flow guide shells 27 respectively. The liquid inside the bottom is thrown to both sides under the action of centrifugal force. A bevel gear 32 is rotatably installed on the rotating rod 26. The outer wall of the rotating sleeve 31 is rotatably installed on the top of the reaction vessel 1. The second bevel gear 33 is fixedly installed on the outer wall of the rotating sleeve 31. When the rotating rod 26 drives the first bevel gear 32 to rotate, the second bevel gear 33 is driven to rotate under the transmission of the third bevel gear 35. Since the first bevel gear 32 and the second bevel gear 33 are installed in opposite directions, the rotating rod 26 and the rotating sleeve 31 rotate in opposite directions. When the multiple connecting rods 36 rotate to stir the liquid, the multiple scrapers 37 contact the inner wall of the heating cylinder 23 to clean the inner wall of the heating cylinder 23.

[0029] Working Principle: With the heating mechanism 2, when the drive motor 25 rotates the rotating rod 26, multiple guide vanes 292 on the three rotating disks 291 on the rotating rod 26 draw the perfluorosulfonic acid resin liquid from the bottom of the guide shell 27 into the interior of the guide shell 27 and throw it out under centrifugal force. This causes the liquid at the bottom of the three guide shells 27 to replace the liquid around the guide shells 27. Meanwhile, the liquid at the bottom of the entire heating cylinder 23 is thrown onto the inner wall of the heating cylinder 23 by the rotating disks 291 for replacement. This improves the overall heating effect and efficiency when the driving heating wire 22 heats the cylinder wall of the heating cylinder 23, preventing the perfluorosulfonic acid resin liquid at the bottom of the heating cylinder 23 from being insufficiently heated during the modification reaction, thus ensuring the uniformity and stability of the reaction. Simultaneously, through continuous liquid circulation and heating, this device promotes a uniform temperature distribution in the reaction system, preventing local overheating or temperature gradients, effectively improving product quality and reaction rate.

[0030] With the cleaning mechanism 3 in place, while the liquid inside the heating cylinder 23 is stirred and heated, the rotating rod 26 drives the rotating sleeve 31 to rotate in the opposite direction through the transmission of bevel gear 1 32, bevel gear 2 33 and bevel gear 35. This causes the scrapers 37 on the multiple connecting rods 36 to scrape and wash the inner wall of the heating cylinder 23, preventing the gel-like perfluorosulfonic acid resin liquid adhering to the heating cylinder 23 from affecting the heating effect and further improving the overall heating efficiency of the device. The feed pipe 38 is used to add raw materials, while the discharge pipe 39 and valve 391 are used to discharge the liquid after the reaction.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
