[0002] Sodium methoxide is a solid, white powder that is flammable and highly corrosive. It is soluble in methanol and ethanol. Industrially, sodium methoxide is produced, stored, and transported as a 27%-31% sodium methoxide solution. Sodium methoxide has a wide range of applications, including catalytic condensation, molecular rearrangement, and double bond addition. It is an intermediate and raw material for the production of dyes, pigments, pharmaceuticals, fragrances, and pesticides. Sodium methoxide solution is prepared by mixing solid sodium hydroxide and methanol in a certain proportion and stirring to dissolve them under certain pressure.

The body is connected to the bottom of the liquid inlet pipe, and the top right end of the body has a feed inlet. By incorporating a conveying assembly, after the raw materials in the reaction vessel have reacted, the drive motor will rotate the conveying blades to transport the material from the reaction vessel through the conveying shell to the discharge inlet for collection.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] Please see Figures 1-4 This utility model provides a technical solution for a production equipment for the alkaline process to prepare sodium methoxide: including a support frame 1, a forward and reverse motor 2, a cooling structure 3, a mounting cylinder 301, a cooling rod 302, a cooling blade 303, a mechanical seal 4, a discharge port 5, a sealing sleeve 6, a drive gear 7, a reaction vessel body 8, a half gear ring 9, a feed port 10, a mounting frame 11, a rack 12, an elastic collection bag 13, an adjusting gear 14, a roller 15, an electric telescopic rod 16, an adjusting frame 17, and a top cover 18.

[0032] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 , Figure 3 and Figure 4As shown, the upper end of the mounting frame 11 is fixedly connected to the upper end face of the top cover 18 by bolts, and the lower outer surface of the top cover 18 is fixedly connected to the upper end of the reactor body 8 by bolts. The inlet 10 in the middle of the mounting frame 11 coincides with the upper opening of the top cover 18. The roller 15 is rotatably connected to the lower inner wall of the adjusting frame 17 via the adjusting gear 14. The adjusting gear 14 forms a lifting structure on the lower side of the mounting frame 11 via the rack 12. A frame structure is formed between the mounting frame 11 and the rack 12. The rack 12 is welded to the middle inner wall of the mounting frame 11. The elastic collection bag 13 has a funnel-shaped structure, and the lower half of the elastic collection bag 13 has a hollow structure. The bag 13 has an elastic structure. Both the upper and lower ends of the elastic collection bag 13 are fixedly connected to the inner wall of the mounting frame 11. The vertical height of the mounting frame 11 is greater than the height of the top cover 18. The lower end of the mounting frame 11 does not intersect with the upper end of the cooling rod 302. The electric telescopic rod 16 drives the adjusting frame 17 to tilt and lift up and down, so that the adjusting gear 14 and the rack 12 can mesh. This makes it easy for the roller 15 to lift up and down and rotate on the lower side of the adjusting frame 17. While the roller 15 is moving, it also crushes the solid raw material in the elastic collection bag 13. The liquid is then mixed through the perforations of the elastic collection bag 13, which facilitates preparation, ensures full solid-liquid fusion, and makes it convenient to use.

[0033] Meanwhile, the top cover 18 is fixedly connected to the reactor body 8 by bolts, and the mounting frame 11 is fixedly connected to the top cover 18 by bolts, which facilitates installation and disassembly, makes it convenient to clean the inner wall of the reactor body 8, and to disassemble and repair the mounting frame 11 for reuse.

[0034] Combination Figure 1 and Figure 2As shown, a half-gear ring 9 is integrally fixedly connected to the outer surface of the reactor body 8. The half-gear ring 9 has a half-tooth block structure, and it is meshed with the driving gear 7 on the right side. The outer surface of the mounting cylinder 301 is fixedly connected to the upper inner wall of the support frame 1, and a cooling rod 302 is fixedly connected inside the mounting cylinder 301. The connection between the cooling rod 302 and the lower end of the mounting cylinder 301 is a hollow structure. A cooling blade 303 is fixedly connected to the outer surface of the cooling rod 302. The cooling blade 303 has a spiral structure, and the cooling blade 303 and the interior of the reactor body 8 form a spiral structure. The rotating structure allows the forward and reverse motor 2 to rotate when the power switch is turned on. This motor drives the drive gear 7 to rotate, which in turn drives the reaction vessel body 8 to rotate by meshing with the half gear ring 9. This facilitates the forward and reverse rotation of the reaction vessel body 8, making it easier to stir the liquid in the reaction vessel body 8 and mix it. At the same time, while the reaction vessel body 8 rotates, the cooling blades 303 remain stationary, but they rotate relative to the reaction vessel body 8, which also facilitates the stirring of the liquid in the reaction vessel body 8. This allows for rapid preparation and improves work efficiency.

[0035] Meanwhile, the mounting cylinder 301 and the discharge port 5 are connected by a mechanical seal 4, which facilitates the sealed rotation of the reactor body 8 through the discharge port 5 on the mounting cylinder 301 to prevent leakage and facilitate use. When discharging, the sealing sleeve 6 is rotated to open, which facilitates the outflow of liquid and collection. The cooling structure 3 cools and lowers the temperature of the solution inside the reactor body 8. The cooling blades 303 increase the contact area with the solution and improve the heat dissipation rate. This is the working process of the production equipment used for the alkaline process to prepare sodium methoxide.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
