Description
Technical Field
[0001] This utility model relates to the field of intelligent purification technology of tetrafluorobutanediol, specifically to a distillation column for intelligent purification of tetrafluorobutanediol that can clean the inner wall. Background Technology
[0002] Tetrafluorobutanediol is a chemical substance, a white to almost white powder or crystal, soluble in water, with various applications in the chemical industry, such as as a solvent, reaction medium, or for the synthesis of other fluorinated compounds. Due to its excellent chemical stability, it is also used in the preparation of high-performance materials and coatings.
[0003] In practical applications, in general, when using a distillation column for the intelligent purification of tetrafluorobutanediol, the material cannot be quickly stirred and heated evenly after entering the heating chamber, which affects gas generation. Furthermore, the generated gas cannot be evenly dispersed into the upper distillation chamber, affecting the distillation efficiency. Additionally, the material sticks to the inner wall of the distillation column after heating, and failure to clean it can shorten the lifespan of the device. Therefore, we propose a lifting device for the induction valve of a water purifier's pure water tank during water production to solve these problems. Utility Model Content

[0023] Compared with the prior art, the beneficial effects of this utility model are: by rapidly stirring the material in the heating chamber, the material can be heated evenly, which facilitates the subsequent generation of material gas. At the same time, after the material is heated and the gas is generated, it can be evenly dispersed into the interior of the distillation chamber, which can improve the precision of gas distillation. In addition, the interior of the heating chamber can be scraped, which can effectively prevent the material from sticking to the inner wall of the heating chamber during heating, and greatly improve the service life of the device.
[0024] 1. This utility model incorporates a rotating shaft, a motor, a stirring rod, and a spring. The stirring rod is positioned on the lower outer side of the rotating shaft, while the motor is connected to the upper part of the rotating shaft. When the motor is turned on, the rotating shaft and stirring rod rotate inside the lower part of the equipment body. The equipment body is divided into two parts: an upper distillation chamber and a lower heating chamber. The rotation of the stirring rod and rotating shaft ensures that the material is heated evenly within the heating chamber. A spring is positioned on the inner side of the stirring rod, and a protective hose is positioned on the outer side of the spring for protection. Due to the elasticity of the spring, the stirring rod vibrates up and down due to the weight of the material when it rotates, further improving the uniformity of material heating.

That is, when the rotating shaft rotates, the connecting rod can drive the scraper to rotate, and the scraper can scrape the lower part of the inner wall of the equipment body, which can prevent the material from sticking to the lower part of the inner wall of the equipment body. At the same time, a rubber pad is set inside the scraper. The rubber pad also has elasticity, which can reduce the vibration generated when the scraper scrapes against the inner wall of the equipment body.
[0026] 3. This utility model features a filter screen installed above the heating chamber inside the lower part of the equipment body. The filter screen prevents materials from entering the distillation chamber during stirring.
[0027] 4.

The support plate is set above the guide plate, and the support plate has a large array of holes inside, so that the gas can enter the interior of the distribution plate through the holes of the support plate. The distribution plate has a small array of holes inside, so that the gas can be evenly dispersed through the small holes inside the distribution plate, thereby making contact with the packing layer.
[0028] 5. This utility model, by setting up a spray head, water pipe, air pump and water tank, installs a spray head above the filter screen. After the material is heated, it can be discharged into the interior of the equipment body through the lower middle part of the equipment body. Since the upper rear side of the spray head is fixedly connected to the water pipe, the air pump installed in the middle of the water pipe can be turned on to draw water from the water tank into the interior of the spray head.

[0037] 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.
[0038] Please see Figures 1-6 The present invention provides the following technical solution:
[0039] Example 1: To address the problems existing in the prior art, this embodiment provides the following technical solution: a distillation tower for the intelligent purification of tetrafluorobutanediol with an inner wall that can be cleaned, comprising a device body 1, with a support frame 2 installed on the lower outer side of the device body 1; a rapid stirring mechanism, located inside the lower part of the device body 1, which can efficiently stir the material inside the heating chamber inside the lower part of the device body 1, allowing the material to be heated evenly, thereby quickly generating gas; a gas uniform dispersion mechanism, located in the middle of the device body 1, which can evenly disperse the heated gas inside the distillation chamber, improving the fineness of gas distillation; and an inner wall cleaning mechanism, located inside the lower part of the device body 1, which can scrape the inner wall of the heating chamber inside the device body 1, preventing the material from sticking during heating, and also includes a spray head 20 for spraying water to clean the heating chamber.First, material is fed into the equipment body 1 through the feed inlet 25 located on the right side. The equipment body 1 is divided into upper and lower sections: the upper section is the distillation chamber, and the lower section is the heating chamber. The material is heated by turning on the heating wire 11 installed on the inner wall of the heating chamber. Then, the motor 4 connected to the upper end of the rotating shaft 3 is turned on, causing the rotating shaft 3 to rotate in the middle of the equipment body 1. Since a stirring rod 5 is installed on the lower outer side of the rotating shaft 3, the stirring rod 5 can evenly stir the material as the rotating shaft 3 rotates. A spring 6 is installed on the inner side of the stirring rod 5, and a spring is installed on the outer side of the spring 6. The protective hose 7 provides protection, while the spring 6 provides elasticity. Due to the weight of the material, the stirring rod 5 can vibrate up and down in the heating chamber, further improving the uniformity of material heating. A connecting rod 8 is installed on the outside of the rotating shaft 3, and a scraper 9 is installed on the outside of the connecting rod 8. When the rotating shaft 3 rotates, the scraper 9 scrapes against the inner wall of the heating chamber, preventing the material from sticking to the inner wall of the heating chamber. In addition, rubber pads 10 are installed at equal intervals inside the scraper 9, which can reduce the vibration of the scraper 9 scraping against the inner wall of the equipment body 1. After the material is heated and generates gas, it can flow into the distillation chamber through the guide plate 13. The gas flows through the distillation chamber. A filter 12 is installed above the heating chamber to prevent material from entering the distillation chamber during stirring. After passing through the guide plate 13, the gas enters the distribution plate 15 through large holes inside the support plate 14. The distribution plate 15 has small holes to ensure even gas dispersion within the distillation chamber, allowing it to contact the packing layer 16. After distillation, some low-boiling-point gases flow out from the connecting pipe 17 and enter the condenser 18. The condenser 18 has condenser pipes inside, and the gas, after condensation, passes through the condenser 18... The liquid flows back into the equipment body 1 from the lower left side of 8. Under the influence of gravity, it falls into the distillation chamber and completes mass and heat transfer with the rising gas. After complete reflux, some of the liquid condensed from the condenser 18 is output to the collection tank 19 for storage. Finally, the waste liquid outlet 24 is opened to discharge the waste liquid, and the valve at the lower middle part of the equipment body 1 is opened to discharge the material. Then, the air pump 22 set in the middle of the water pipe 21 is opened to pump the water in the water tank 23 into the spray head 20 connected to the front of the water pipe 21. The spray head 20 will spray into the heating chamber to clean it.
[0040] In existing distillation columns, the material cannot be rapidly stirred and heated uniformly after entering the internal heating chamber, which affects gas generation. Therefore, this embodiment addresses this issue through the following technical solution: Figure 3 , Figure 4 and Figure 6As shown, the rapid stirring mechanism includes a rotating shaft 3 located in the middle of the equipment body 1. A stirring rod 5 is installed on the outer side below the rotating shaft 3, and a motor 4 is connected to the top of the rotating shaft 3. When the motor 4 is turned on, the rotating shaft 3 and the stirring rod 5 can rotate inside the lower part of the equipment body 1. The interior of the equipment body 1 is divided into two parts: an upper distillation chamber and a lower heating chamber. When the stirring rod 5 and the rotating shaft 3 rotate, the material can be heated evenly inside the heating chamber. At the same time, a spring 6 is installed on the inner side of the stirring rod 5, and a protective hose 7 is installed on the outer side of the spring 6 for protection. Because the spring 6 has elasticity, when the stirring rod 5 rotates and stirs, the stirring rod 5 can vibrate up and down due to the gravity of the material, which can further improve the uniformity of material heating.
[0041] Example 2: In existing distillation columns, the generated gas cannot be evenly dispersed into the distillation chamber above the column, which affects the gas distillation effect. Therefore, this embodiment addresses this issue through the following technical solution: Figure 3 , Figure 4 and Figure 5 As shown, the gas uniform dispersion mechanism includes a guide plate 13 disposed inside the equipment body 1. The guide plate 13 can guide the gas after the material is heated and stirred to the upper distillation chamber of the equipment body 1. A support plate 14 is disposed above the guide plate 13. The support plate 14 has large holes arranged in an array inside, that is, the gas can enter the interior of the distribution plate 15 through the holes of the support plate 14. The distribution plate 15 has small holes arranged in an array inside, that is, the gas can be uniformly dispersed through the small holes arranged inside the distribution plate 15, thereby making contact with the packing layer 16.
[0042] Example 3: In existing distillation columns, the material entering the heating chamber tends to stick to the inner wall of the column. Failure to clean this can affect the lifespan of the equipment. Therefore, this embodiment addresses this issue through the following technical solution: Figure 3 , Figure 4 and Figure 6As shown, the internal cleaning mechanism includes a connecting rod 8 located on the outer side below the rotating shaft 3. A scraper 9 is installed on the outer side of the connecting rod 8. The outer side of the scraper 9 is tightly fitted to the lower interior of the equipment body 1. When the rotating shaft 3 rotates, the connecting rod 8 drives the scraper 9 to rotate. The scraper 9 can scrape the lower interior wall of the equipment body 1, preventing materials from sticking to the lower interior wall of the equipment body 1. At the same time, a rubber pad 10 is installed inside the scraper 9. The rubber pad 10 also has elasticity, which can reduce the vibration generated when the scraper 9 scrapes against the inner wall of the equipment body 1. When the material is heated, it can be discharged into the interior of the equipment body 1 through the lower middle part of the equipment body 1. Since the upper rear side of the spray head 20 is fixedly connected to the water pipe 21, the air pump 22 installed in the middle of the water pipe 21 can be turned on, and the air pump 22 can draw water from the water tank 23 into the interior of the spray head 20. The spray head 20 can spray the heating chamber in the lower interior of the equipment body 1, thereby cleaning the heating chamber.
[0043] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
