Description

Technical Field

[0001] This utility model relates to the field of distillation kettle technology, specifically a rectification distillation kettle for improving distillation efficiency. Background Technology

[0002] A distillation kettle is a device used to separate liquid mixtures and is widely used in industries such as chemical, pharmaceutical, and food processing. It separates the components by heating them to evaporate the different components and utilizing the differences in their boiling points.

[0003] Patent CN213433026U discloses a high-efficiency distillation kettle, belonging to the field of distillation technology. The high-efficiency distillation kettle includes a kettle body, a sealing cap at the top of the kettle body, and several sets of latches at the connection between the sealing cap and the kettle body. A distillation port is located on one side of the top of the sealing cap, and a vent pipe is connected to the top of the distillation port. A feed inlet is located on the other side of the top of the sealing cap, and a first hinge is located on one side of the feed inlet. The first hinge is hinged to the cap body. Pressure boosting pipes are connected to both sides of the kettle body, and a pressure booster is connected to the side of the pressure boosting pipes furthest from the kettle body. This distillation kettle effectively solves the problem of rapid and efficient distillation of substances in a distillation kettle, avoiding situations where prolonged distillation time causes changes in the substances in the distillation kettle, thus failing to achieve the expected results. This improves the efficiency of distillation work. Furthermore, stirring during the distillation process facilitates the distillation process and effectively improves the work efficiency of the operators.

[0004] However, the above-mentioned distillation vessel still has the following problems in actual use:

[0005] During distillation in a still, some problems may arise due to the characteristics of the materials being processed. For example, under high-temperature conditions, some materials may decompose or undergo chemical reactions, resulting in solid residues on the inner wall of the still. As these residues accumulate, they not only reduce heat transfer efficiency but may also cause pipe blockages, thus adversely affecting the distillation process. However, most stills currently lack features for cleaning the inner wall, a design limitation that makes it difficult to achieve ideal distillation results and increases the difficulty of subsequent maintenance. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a distillation kettle that improves distillation efficiency, allowing for scraping and cleaning of the inner wall of the kettle body during operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a distillation kettle for improving distillation efficiency, comprising a kettle body and a kettle cover installed on the upper end of the kettle body. A power mechanism is connected to the upper surface of the kettle cover. The output end of the power mechanism extends through the outer wall of the kettle cover into the interior of the kettle body and is connected to a stirring assembly. The other end of the stirring assembly is connected to several moving components. The other end of the moving components is connected to a scraper. A gas supply mechanism is provided below the kettle body. The output end of the gas supply mechanism extends through the outer wall of the kettle body into the interior of the kettle body and is connected to the power mechanism.

[0008] Furthermore, the power mechanism includes a stirring motor and a rotating rod. The outer wall of the stirring motor is fixedly connected to the upper surface of the vessel lid. The output shaft of the stirring motor is fixedly connected to the upper end of the rotating rod. The lower end of the rotating rod passes through the outer wall of the vessel lid and extends into the interior of the distillation vessel body. The end of the rotating rod located inside the distillation vessel body is connected to both the stirring assembly and the gas supply mechanism.

[0009] Furthermore, the stirring assembly includes several stirring rods arranged parallel to each other, with one end of each stirring rod fixedly connected to the outer wall of the rotating rod located inside the distillation vessel body, and the other end of each stirring rod connected to several moving components.

[0010] Furthermore, the inner wall of the rotating rod is provided with a main air chamber, and the inner walls of several stirring rods are provided with secondary air chambers. The air supply mechanism, the main air chamber and several secondary air chambers are internally connected, and the moving component is located inside the secondary air chamber at the end away from the main air chamber.

[0011] Furthermore, the moving assembly includes an extension rod and a piston. The outer wall of the piston is slidably connected to the inner wall of the secondary air chamber. One end of the piston away from the main air chamber is fixedly connected to one end of the extension rod, and the other end of the extension rod passes through the outside of the secondary air chamber and is fixedly connected to the outer wall of the scraper.

[0012] Furthermore, the gas supply mechanism includes a base, a gas pump, and a gas outlet pipe. The outer wall of the base is fixedly connected to the outer wall of the gas pump.

[0013] Furthermore, several waterproof rings are fixedly connected to the side of the scraper near the extension rod, and the inner walls of the several waterproof rings are slidably connected to the outer walls of several stirring rods.

[0023] 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.

[0024] Please see Figures 1-4 A distillation kettle for improving distillation efficiency includes a kettle body 1 and a kettle cover 2 installed on the upper end of the kettle body 1. A power mechanism is connected to the upper surface of the kettle cover 2. The output end of the power mechanism extends through the outer wall of the kettle cover 2 into the interior of the kettle body 1 and is connected to a stirring assembly. The other end of the stirring assembly is connected to several moving components. The other end of the moving components is connected to a scraper 9. A gas supply mechanism is provided below the kettle body 1. The output end of the gas supply mechanism extends through the outer wall of the kettle body 1 into the interior of the kettle body 1 and is connected to the power mechanism.

[0025] like Figures 1 to 4 As shown, in the distillation kettle of this invention, which improves distillation efficiency, some solid impurities adhere to the inner wall of the kettle body 1 due to the evaporation of different media. To avoid these impurities affecting the normal operation of the kettle body 1, the stirring mechanism can be activated simultaneously with distillation. After the stirring mechanism is activated, the output end rotates the stirring component located inside the kettle body 1. As the stirring component rotates, the various media inside the kettle body 1 are heated more evenly. Furthermore, to prevent impurities from adhering, the gas supply mechanism can be activated at intervals. After the gas supply mechanism is activated, gas is delivered to the rear of the moving component through the power mechanism. The moving component is then pushed by the high-pressure gas, causing the scraper 9 to press against the inner wall of the kettle body 1. As the stirring component continues to rotate, the scraper 9 scrapes off the solid impurities adhering to the inner wall of the kettle body 1, thus avoiding affecting the heat transfer efficiency or even causing pipe blockage.

[0026] It should be noted that the purpose of setting the gas supply mechanism to be turned on at intervals is to avoid the scraper 9 from being constantly pressed against the inner wall of the distillation vessel body 1, which would cause a certain degree of wear. As the wear becomes more and more serious, it may lead to a reduction in the cleaning effect of the scraper 9.

[0027] Please refer to the following: Figure 2 and Figure 3 The power mechanism includes a stirring motor 3 and a rotating rod 7. The outer wall of the stirring motor 3 is fixedly connected to the upper surface of the kettle cover 2. The output shaft of the stirring motor 3 is fixedly connected to the upper end of the rotating rod 7. The lower end of the rotating rod 7 passes through the outer wall of the kettle cover 2 and extends into the interior of the distillation kettle body 1. The end of the rotating rod 7 located inside the distillation kettle body 1 is connected to both the stirring assembly and the gas supply mechanism.

[0028] More specifically, when it is necessary to control the rotation of the stirring component, simply turn on the stirring motor 3. The output shaft of the stirring motor 3 will then rotate the rotating rod 7. The rotation of the rotating rod 7 will cause the stirring component connected to its surface to rotate, thereby achieving the purpose of stirring the medium inside the distillation vessel body 1.

[0029] Please refer to the following: Figures 2-4 The stirring assembly includes several stirring rods 8, which are arranged in parallel vertically. One end of each stirring rod 8 is fixedly connected to the outer wall of the rotating rod 7 located inside the distillation vessel body 1. The other end of each stirring rod 8 is connected to several moving components.

[0030] More specifically, when the rotating rod 7 rotates, it will also rotate the stirring rod 8. Then, when the stirring rod 8 rotates, it will also rotate the scraper 9. At the same time, the stirring rod 8 will also carry the medium inside the distillation vessel body 1 to flow, so that this part of the medium is heated more evenly.

[0031] Please refer to the following: Figure 3 The inner wall of the rotating rod 7 is provided with a main air chamber 11, and the inner walls of several stirring rods 8 are provided with secondary air chambers 12. The air supply mechanism, the main air chamber 11 and the several secondary air chambers 12 are internally connected, and the moving component is located inside the secondary air chamber 12 at the end away from the main air chamber 11.

[0032] More specifically, by setting up the main air chamber 11 and the secondary air chamber 12, not only can the moving component be provided with storage and support, but the gas supplied by the air supply mechanism can also be applied more accurately to the rear of the moving component.

[0033] Please refer to the following: Figure 3 and Figure 4 The moving assembly includes an extension rod 13 and a piston 14. The outer wall of the piston 14 is slidably connected to the inner wall of the secondary air chamber 12. One end of the piston 14 away from the main air chamber 11 is fixedly connected to one end of the extension rod 13. The other end of the extension rod 13 passes through the outside of the secondary air chamber 12 and is fixedly connected to the outer wall of the scraper 9.

[0034] More specifically, when the gas supply mechanism is started, it will deliver gas into the main gas chamber 11 of the rotating rod 7. Then, this gas will enter the secondary gas chamber 12 through the main gas chamber 11, and then push the piston 14 and the extension rod 13 forward, so that the scraper 9 can be pushed against the inner wall of the distillation vessel body 1 through the extension rod 13.

[0035] Please refer to the following: Figures 1-3 The gas supply mechanism includes a base 4, a gas pump 5, and a gas outlet pipe 6. The outer wall of the base 4 is fixedly connected to the outer wall of the gas pump 5. The output end of the gas pump 5 is fixedly connected to one end of the gas outlet pipe 6. The other end of the gas outlet pipe 6 passes through the outer wall of the distillation vessel body 1 and extends into the interior of the rotating rod 7. The outer wall of the gas outlet pipe 6 is rotatably connected to the inner wall of the main gas chamber 11. The gas pump 5, the gas outlet pipe 6, and the interior of the main gas chamber 11 are connected.

[0036] More specifically, when it is necessary to control the movement of scraper 9, simply turn on air pump 5. After air pump 5 is started, the gas inside air pump 5 will be output to the main air chamber 11 of rotating rod 7 through air outlet pipe 6, and then scraper 9 can be pushed to move towards distillation kettle body 1.

[0037] Conversely, when it is necessary to stop scraping the inner wall of the distillation vessel body 1, simply control the air pump 5 to draw in air, and the gas inside the main gas chamber 11 and the secondary gas chamber 12 can be drawn back into the air pump 5 through the air outlet pipe 6. Then the scraper 9 can be disconnected from the distillation vessel body 1.

[0038] Please refer to the following: Figures 2-4 Several waterproof rings 10 are fixedly connected to the side of the scraper 9 near the extension rod 13, and the inner walls of the several waterproof rings 10 are slidably connected to the outer walls of several stirring rods 8 respectively.

[0039] More specifically, by setting a waterproof ring 10 and a sealing ring at the connection between the waterproof ring 10 and the stirring rod 8, the scraper 9 can be sealed during the movement of the scraper 9 under the push of the extension rod 13, reducing the difficulty of subsequent large-scale cleaning.

[0040] Please refer to the following: Figure 2 and Figure 3 The number of stirring components shall not be less than two sets, and several sets of stirring components shall be evenly distributed around the rotating rod 7.

[0041] More specifically, the number of stirring components is multiple, which can improve the uniformity of stirring inside the distillation vessel body 1.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
