Description

A reaction vessel for the preparation of sodium methoxide Technical Field

[0001] This utility model relates to the field of sodium methoxide preparation technology, specifically a reaction vessel for sodium methoxide preparation. Background Technology

[0002] Sodium methoxide is a compound formed by the reaction of methanol and sodium hydroxide. It is produced by the reaction of metallic sodium with methanol. During the reaction, the temperature and hydrogen emissions need to be strictly controlled. A catalyst is often added to improve the reaction efficiency, and nitrogen is used for protection to prevent oxidation. Sodium methoxide is prepared by using a reaction vessel for sodium methoxide preparation.

[0003] The temperature of the reaction vessel for sodium methoxide preparation is controlled by a heating element inside the vessel. During the reaction, the vessel is stirred by a stirring mechanism. After the reaction is completed, the material can be discharged through a valve at the bottom of the vessel. During discharge, material will adhere to the inner wall of the vessel. However, there is no corresponding cleaning mechanism, so manual cleaning is required, which is not very efficient.

[0004] Therefore, we propose a novel reaction vessel for the preparation of sodium methoxide to solve the above-mentioned technical problems. Summary of the Invention

[0033] Example 1

[0034] This embodiment provides a technical solution: a reaction vessel for the preparation of sodium methoxide, as shown in Figures 1-5, including a sodium methoxide preparation tank, a rotating cleaning mechanism, a rotating drive mechanism, a sealing cover mechanism, and a rotating stirring mechanism.

[0035] The rotating cleaning mechanism is movably installed on the inner side of the upper end of the sodium methoxide preparation tank. This mechanism can rotate circumferentially on the inner side of the upper end of the tank, thus cleaning any deposits adhering to the inner wall. The rotating drive mechanism is fixed to the outer side of the upper end of the sodium methoxide preparation tank, providing stable drive. This drive mechanism meshes with the rotating cleaning mechanism, transmitting power to it. The sealing cover mechanism is installed on the inner side of the upper end of the sodium methoxide preparation tank via screws. This seals the inner side of the tank and allows material to be added. The rotating stirring mechanism is installed and connected to the inner center of the sealing cover mechanism, driving rotation within the sealing cover mechanism for stirring.

[0036] As shown in Figures 1 and 2, the sodium methoxide preparation tank includes a tank shell 4. A tank heating element 2 is installed inside the tank shell 4. The tank heating element 2 can heat the tank shell 4 when energized. An observation window 1 is installed in the middle of the front end of the tank shell 4 by screws for easy inspection. A valve pipe 3 is fixedly connected through the middle of the lower end of the tank shell 4. The material prepared by the reaction in the tank shell 4 can be effectively discharged through the valve pipe 3. A tank support leg 41 is fixedly connected to the outside of the valve pipe 3 on the tank shell 4. The tank shell 4 can be supported and placed by the tank support leg 41. A cover mounting cavity 42 is opened on the inner side of the upper end of the tank shell 4. A sealing cover plate mechanism is installed in the cover mounting cavity 42, so that the tank shell 4 can be installed accordingly.

[0037] As shown in Figures 1 and 3, the sealing cover mechanism includes a cover shell 6, which is installed on the tank shell 4 by screws. The cover shell 6 can effectively close the upper opening of the tank shell 4. A feed pipe 62 is fixedly connected to the inner side of the left end of the cover shell 6. The feed pipe 62 can stably receive materials on the cover shell 6 and then add them to the tank shell 4. An exhaust pipe 61 is fixedly connected to the inner side of the right end of the cover shell 6. The exhaust pipe 61 can stably discharge gas on the cover shell 6. A rotating stirring mechanism is installed in the middle of the inner side of the cover shell 6. The rotating stirring mechanism can stably rotate and stir on the cover shell 6.

[0038] A sealing rubber ring is installed at the connection between the cover shell 6 and the tank shell 4, so that the fixing is more tight.

[0039] During use, the sealing cover mechanism can be closed inside the upper part of the sodium methoxide preparation tank, and materials can be added to the sodium methoxide preparation tank. The rotating stirring mechanism can be driven to rotate inside the middle of the sealing cover mechanism, thereby rotating and stirring inside the sodium methoxide preparation tank, effectively accelerating the reaction preparation speed. After discharge, the rotating drive mechanism can be stably driven outside the upper part of the sodium methoxide preparation tank. The rotating drive mechanism meshes with the rotating cleaning mechanism, which can drive the rotating cleaning mechanism to rotate circumferentially inside the upper part of the sodium methoxide preparation tank, thereby cleaning the inner wall of the sodium methoxide preparation tank. This automatic cleaning makes cleaning more efficient and convenient.

[0041] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those in the aforementioned technical solutions will not be repeated here. As shown in Figures 1-5, in order to better realize this utility model, the following configuration is adopted: The rotation drive mechanism includes a hollow lug 51, which is fixedly connected to the outer shell 4 of the tank, so that the hollow lug 51 can be placed stably. A cleaning motor 5 is installed on the inner side of the upper end of the hollow lug 51 by screws. The cleaning motor 5 can be stably driven on the hollow lug 51. The output shaft end of the cleaning motor 5 is fixedly connected to a drive gear 52 located inside the hollow lug 51. When the output shaft of the cleaning motor 5 rotates, it can drive the drive gear 52 to rotate. The drive gear 52 meshes with the rotation cleaning mechanism, and the drive gear 52 can actively drive the rotation cleaning mechanism to perform cleaning rotation.

[0042] The rotating cleaning mechanism includes a rotating disc 8, with an outer gear ring 81 fixedly connected to the outer circumference of the outer wall of the rotating disc 8. The rotating disc 8 and the outer gear ring 81 are rotatably mounted on the outer shell 4 of the tank, so that the rotating disc 8 and the outer gear ring 81 can be positioned and rotated in the outer shell 4 of the tank. A cleaning scraper 82 is fixedly connected to the lower end of the rotating disc 8. The cleaning scraper 82 contacts the inner wall of the outer shell 4 of the tank, so that the rotating disc 8 can drive the cleaning scraper 82 to rotate during rotation. The cleaning scraper 82 can effectively clean the deposits on the inner wall of the outer shell 4 of the tank during rotation. The outer gear ring 81 meshes with the drive gear 52, which can stably mesh and transmit power.

[0043] Example 3

[0044] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those in the aforementioned technical solutions will not be repeated here. As shown in Figures 1, 2, 3 and 5, in order to better realize this utility model, the following configuration is adopted: The rotating stirring mechanism includes a stirring motor 7, which is mounted on the cover plate housing 6 by screws. The stirring motor 7 can be stably driven on the cover plate housing 6. The output shaft of the stirring motor 7 is fixedly connected to a first coupling 71 that passes through the cover plate housing 6. When the output shaft of the stirring motor 7 rotates, it can drive the first coupling 71 to rotate. The lower end of the first coupling 71 is fixedly connected to a stirring main rod 73. The first coupling 71 can drive the stirring main rod 73 to rotate. The outer wall of the stirring main rod 73 is symmetrically fixedly connected to stirring side rods 72. The stirring main rod 73 can drive the stirring side rods 72 to rotate and stir.

[0045] The stirring side rod 72 and the stirring main rod 73 are sleeved inside the middle of the outer shell 4 of the tank, so that they can be stirred and reacted accordingly.

Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
