Abstract
Description
Technical Field
[0001] This utility model relates to the field of perfluoroalkyl iodide distillation and purification technology, specifically to a perfluoroalkyl iodide distillation and purification device. Background Technology
[0002] Perfluoroalkyl iodides are a class of fluorinated organic compounds whose molecular structure consists of a fully fluorinated carbon chain (i.e., perfluoroalkyl) directly linked to an iodine atom. Perfluoroalkyl refers to a straight-chain or branched group in which all hydrogen atoms in the alkyl group are replaced by fluorine atoms, such as perfluorobutyl, perfluorohexyl, and perfluorooctyl. These compounds are named according to the rule of "perfluoro[carbon chain name] iodine", such as perfluorohexyl iodine and perfluorooctyl iodine. Their physical properties are significantly affected by the strongly electronegative fluorine atom: they are usually characterized by high density, high boiling point, low surface tension, and high viscosity in the liquid state. Chemically, the iodine atom, as a relatively active site, can participate in a variety of substitution or coupling reactions, making it an important intermediate in the synthesis of other fluorinated compounds (such as perfluoroalkyl alcohols, carboxylic acids, or more complex fluorinated surfactants).
[0003] Currently available perfluoroalkyl iodide distillation purification equipment can only heat the bottom of the storage tank during use, resulting in uneven heating of the solution and thus poor distillation purity. Furthermore, water droplets condense slowly during collection, leading to low collection efficiency. Therefore, there is an urgent need for a new perfluoroalkyl iodide distillation purification equipment to improve these problems. Utility Model Content

The hook 11 and the rotating frame 13 are respectively fixedly connected to the two ends of the electric push rod 12. The rotating frame 13 is rotatably connected to the inside of the limiting frame 14. In this embodiment, the limiting block 10 plays the role of locking the hook 11, the hook 11 plays the role of positioning, the rotating frame 13 plays the role of facilitating the rotation of the electric push rod 12, and the electric push rod 12 plays the role of driving the hook 11 to move.
[0033] Reference Figure 5 and Figure 6 The other end of the connecting pipe 1 is provided with a collection device 18, which includes a collection tank 19. A pressure relief valve 20 is provided on the top of the collection tank 19. An installation rod 21 is provided inside the collection tank 19. A scraper 22 is provided on the outside of the installation rod 21. A constant speed motor 23 is provided at the bottom of the installation rod 21. An electronic valve 24 is provided on one side of the collection tank 19. In this embodiment, the collection tank 19 serves to store distilled liquid, and the pressure relief valve 20 serves to release air.
[0034] Reference Figure 5 and Figure 6 The pressure relief valve 20 is fixedly connected to the top of the collection tank 19, the mounting rod 21 is rotatably connected to the inside of the collection tank 19, and the scraper 22 is fixedly connected to the outside of the mounting rod 21. In this embodiment, the mounting rod 21 drives the scraper 22 to rotate, and the scraper 22 accelerates the accumulation of water vapor.
[0035] Reference Figure 5 and Figure 6 The constant speed motor 23 is fixedly connected to the bottom of the collection tank 19, and the electronic valve 24 is fixedly connected to the outside of the collection tank 19. In this embodiment, the constant speed motor 23 drives the mounting rod 21 to rotate.
[0036] The implementation principle of this embodiment is as follows:
[0037] During use, the solution to be distilled is placed inside the storage cylinder 6, and then the storage cylinder 6 is placed inside the insulation box 3. When placing the storage cylinder 6 into the insulation box 3, the limiting groove 7 needs to be aligned with the limiting plate 5, allowing the limiting groove 7 to slide on the outside of the limiting plate 5. After the storage cylinder 6 enters the insulation box 3, the sealing cap 9 needs to be snapped onto the top of the storage cylinder 6 and the insulation box 3. Note: "The limiting block 10 and the limiting frame 14 need to be aligned." After placing the sealing cap 9 on top of the storage cylinder 6 and the insulation box 3, the operator will operate the electric... As the push rod 12 rotates, the rotating frame 13 will be inside the limiting frame 14 until the output shaft of the electric push rod 12 faces upward and is in a near-vertical position. At this time, the output shaft of the electric push rod 12 begins to retract and drives the hook 11 to move downward. As the output shaft of the electric push rod 12 continues to retract, the distance between the hook 11 and the limiting block 10 will gradually decrease. After the output shaft of the electric push rod 12 is fully retracted, the hook 11 will be engaged with the top of the limiting block 10, and the sealing cover 9 will be firmly engaged with the top of the storage cylinder 6 and the insulation box 3.
[0038] After the storage cylinder 6 is placed inside the insulation box 3 and the sealing cover 9 is fixed, a water pipe (or other water supply equipment) needs to be connected to the hot water tank 4 to supply water to the hot water tank 4. After entering the hot water tank 4, the water will be heated quickly and pumped to the insulation box 3 through the output tank using the water pump 17. As hot water continuously enters the insulation box 3, it will gradually fill the insulation box 3 and wrap the storage cylinder 6 with hot water. The hot water entering the insulation box 3 will flow back to the hot water tank 4 through the output pipe 15 to complete the water circulation. As the circulation time increases, the temperature of the hot water will gradually reach 100 degrees, which is sufficient to make the solution inside the storage cylinder 6 boil and form water vapor. The water vapor enters the collection tank 19 through the connecting pipe 1.
[0039] When water vapor enters the inside of the collecting tank 19, some of it will quickly condense into distillate and fall to the bottom of the collecting tank 19, while some of it will be adsorbed onto the inner wall of the collecting tank 19. At this time, the constant speed motor 23 starts to work and drives the mounting rod 21 to rotate inside the collecting tank 19. The mounting rod 21 drives the scraper 22 to rotate. The scraper 22 is in contact with the inner wall of the collecting tank 19, gathering the water vapor adsorbed onto the inner wall together and accelerating the collection of distillate. The electronic valve 24 opens when discharging distillate, while the pressure relief valve 20 plays the role of venting excess air.
[0040] Compared with the prior art, the present invention has the following advantages:
[0041] The hot water tank 4, output pipe 15, and water pump 17 work together to add hot water to the insulation box 3. The output pipe 15, in conjunction with the hot water tank 4, facilitates the outflow of water from the insulation box 3. The limiting plate 5 and limiting groove 7 work together to store the solution. The hook 11 and limiting block 10 work together to seal the cover 9. The limiting frame 14, rotating frame 13, and electric push rod 12 work together to move the hook 11. By using the above structure, a storage system can be used. The increased heating surface of cylinder 6 ensures uniform heating of the internal solution, thereby guaranteeing distillation purity. The addition of collection tank 19 stores the distillate, while the addition of pressure relief valve 20 allows for air venting. The combination of constant speed motor 23 and mounting rod 21 drives scraper 22 to rotate, accelerating the fusion of the distillate. The addition of electronic valve 24 facilitates the discharge of the distillate. By using the above structure, the distillate can be quickly fused together, thus improving collection efficiency.
[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
