Description

Technical Field

[0001] This utility model relates to the field of methyl lauroyl acetate production technology, and in particular to a production reactor. Background Technology

[0002] Methyl lauroyl acetate is a methyl carboxylic acid ester compound containing a ketone group. It appears as a solid with a melting point of 29-30℃ and a boiling point of 296.9℃. It is soluble in chloroform, ethyl acetate, and methanol. This substance is often used as an intermediate in the fields of fragrance, cosmetics, and pharmaceuticals. The ketone group and long-chain alkyl group in its molecular structure endow it with specific chemical activities, making it of great application value in organic synthesis. During the production process, attention should be paid to the pretreatment of the reactor feed and the stirring efficiency to ensure the purity and yield of the product.

[0003] In the production of methyl lauroyl acetate, the reactor is one of the core pieces of equipment, and its performance directly affects the reaction efficiency and product quality. However, the feed structure of existing reactors often lacks an effective pretreatment device, which cannot fully crush and homogenize the raw materials. This results in the raw material particles being too large or uneven when fed into the reactor, leading to incomplete reaction and reduced product yield. At the same time, the stirring components of traditional reactors are relatively simple in structure, usually only having basic stirring functions, making it difficult to achieve comprehensive and uniform mixing of materials in the reactor. Material adhesion and stirring dead zones are prone to occur near the inner wall of the reactor, resulting in uneven reaction and affecting product quality. Utility Model Content

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1:

[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a production reactor, including a reactor body 1. A tank cover 2 is installed on the top of the reactor body 1 through a connecting flange. A stirring assembly 3 is provided inside the reactor body 1. An addition pipe 4 and a feed pipe 5 are respectively connected to the top of the tank cover 2.

[0029] The reactor body 1 serves as the container for the entire reaction process, providing a specific space and environment for the reaction of methyl lauroyl acetate, allowing it to undergo a chemical reaction to generate the desired product. The lid 2 seals the reactor, preventing leakage of methyl lauroyl acetate and the entry of external impurities during the reaction. The stirring assembly 3 agitates the methyl lauroyl acetate within the reactor body 1, ensuring thorough mixing, promoting the chemical reaction, and improving reaction efficiency and product quality. It also scrapes away methyl lauroyl acetate adhering to the reactor's inner wall, preventing scaling and ensuring efficient reaction. The addition pipe 4 allows for the addition of specific additives or auxiliary reagents to meet different reaction conditions or product performance requirements. The feed pipe 5 is the main channel for methyl lauroyl acetate to enter the reactor body 1.

[0030] A limit frame 6 is fixed to the inner wall of the feed pipe 5. A rotating shaft 7 is rotatably connected to the inner wall of the limit frame 6. A churning paddle 8 is fixed to the top of the rotating shaft 7. A funnel 9 is connected to the top of the feed pipe 5. A temporary storage box 10 is provided on the top of the funnel 9.

[0031] The limiting frame 6 not only provides rotational support for the rotating shaft 7, but also restricts the rotational position of the rotating shaft 7, ensuring that the agitator 8 works stably in the feed pipe 5. The rotating shaft 7, driven by the first motor 18, drives the agitator 8 to rotate through the meshing transmission of the first bevel gear 19 and the second bevel gear 20, thereby agitating the larger particles of methyl lauroyl acetate entering the feed pipe 5, making the particle size of methyl lauroyl acetate more uniform, which is conducive to the full reaction in the reactor. The agitator 8 can rotate with the rotating shaft 7 to agitate the methyl lauroyl acetate passing through the feed pipe 5, improve the reactivity of methyl lauroyl acetate, and ensure that the reaction can proceed efficiently and uniformly. The funnel 9 can guide the methyl lauroyl acetate to smoothly enter the feed pipe 5. The temporary storage box 10 is used to temporarily store the methyl lauroyl acetate to be added to the reactor, so that the operator can control the amount of methyl lauroyl acetate added in a timely manner according to the reaction progress and needs.

[0032] The stirring assembly 3 includes a stirring rod 31 disposed inside the reactor body 1. A stirring blade 32 is fixed to the outside of the stirring rod 31. A connecting rod 33 is fixed to the outside of the stirring rod 31. A vertically arranged scraper 34 is fixed to one end of the connecting rod 33, and the outside of the scraper 34 is in contact with the inner wall of the reactor body 1.

[0033] The stirring rod 31 can rotate under the drive of the second motor 25, driving the stirring blade 32, connecting rod 33 and scraper 34 to move together, thereby stirring and mixing methyl lauroyl acetate in the reactor. The stirring blade 32 can rotate with the stirring rod 31 to stir the methyl lauroyl acetate in the reactor, so that the methyl lauroyl acetate is fully mixed, promoting the chemical reaction, improving reaction efficiency and product quality. The connecting rod 33 is set to fix the stirring rod 31 and the scraper 34, so that the scraper 34 can move with the stirring rod 31. The scraper 34 is set to scrape off the methyl lauroyl acetate adhering to the inner wall of the reactor, preventing the methyl lauroyl acetate from scaling on the inner wall of the reactor, which would affect the reaction efficiency of the reactor, and at the same time ensuring the cleanliness of the inner wall of the reactor, which is convenient for equipment maintenance and cleaning.

[0034] Example 2:

[0035] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the top of the temporary storage box 10 is hinged to a box cover 11, and a first control valve 12 is provided on the outside of the funnel 9.

[0037] The cover 11 is designed to prevent the methyl lauroyl acetate in the storage tank 10 from being contaminated by the outside environment, while also facilitating the addition of methyl lauroyl acetate. The first control valve 12 is designed to control the flow rate of methyl lauroyl acetate from the storage tank 10 through the funnel 9 into the feed pipe 5, ensuring that the amount of methyl lauroyl acetate added to the reactor meets the reaction requirements.

[0038] Specifically, a sealing cover 13 is provided on the inner wall of the feed pipe 5, and a sealing strip 14 is fixed on the outer side of the sealing cover 13. The outer side of the sealing strip 14 fits into the inner wall of the feed pipe 5. Fixing strips 15 are fixed on the outer side of both the feed pipe 5 and the sealing cover 13, and fixing bolts 16 are provided between the two sets of fixing strips 15.

[0039] The sealing cap 13 is used to seal the feed pipe 5 to prevent leakage of gas or methyl lauroyl acetate in the reactor. When open, it facilitates maintenance or replacement of the agitation mechanism inside the feed pipe 5. The sealing strip 14 fits into the inner wall of the feed pipe 5 to enhance the sealing effect and ensure the reliability of the seal. The fixing strip 15 is used to provide an installation position for the fixing bolt 16. The fixing bolt 16 can pass through the inner wall of the two sets of fixing strips 15 to firmly fix the sealing cap 13 to the feed pipe 5, ensuring the stability of the sealing cap 13 in the closed state.

[0040] Specifically, a housing 17 is installed on the outside of the feed pipe 5, and a first motor 18 is installed inside the housing 17.

[0041] The outer casing 17 serves to protect the first motor 18 and prevent damage to it from the external environment. The first motor 18 is used to provide power for the rotation of the pulverizing paddle 8, and drives the rotating shaft 7 to rotate through the first bevel gear 19 at the output end.

[0042] Specifically, a first bevel gear 19 is fixed to the output end of the first motor 18, a second bevel gear 20 is fixed to the bottom end of the rotating shaft 7, and the inner wall of the second bevel gear 20 meshes with the inner wall of the first bevel gear 19. A protective shell for protecting the first bevel gear 19 and the second bevel gear 20 is fixed to the inner wall of the limiting frame 6.

[0043] The second bevel gear 20 works in conjunction with the first bevel gear 19 to transmit the rotational power of the first motor 18 to the rotating shaft 7, thereby transmitting power and changing its direction. This allows the rotating shaft 7 to drive the churning paddle 8 to rotate. The protective shell is designed to protect the first bevel gear 19 and the second bevel gear 20, preventing materials or impurities from entering the gear meshing area and affecting the normal operation of the gears.

[0044] Example 3:

[0045] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, an installation block 21 is fixed on the outside of the reactor body 1, and a discharge pipe 22 is connected to the bottom of the reactor body 1. A second control valve 23 is installed on the outside of the discharge pipe 22.

[0047] The mounting block 21 is used to install the reactor body 1 and ensure the stability of the reactor body 1 during use. The discharge pipe 22 is the channel for the product to be discharged from the reactor after the reaction is completed. The second control valve 23 is used to control the discharge flow rate and speed of the reaction product.

[0048] Specifically, a fixing bracket 24 is fixed to the top of the can lid 2, and a second motor 25 is installed on the top of the fixing bracket 24. The output end of the second motor 25 is fixedly connected to the top of the stirring rod 31 through a flange.

[0049] The mounting bracket 24 is provided to support the second motor 25, which in turn provides power to the stirring assembly 3, driving the stirring rod 31, stirring blade 32, and scraper 34 to rotate.

[0050] Working Principle: When using this production reactor, first open the cover 11 on the temporary storage tank 10 and add the methyl lauroyl acetate to be reacted into the temporary storage tank 10. Then, close the cover 11 to prevent the methyl lauroyl acetate from being contaminated by the outside. Next, open the first control valve 12, and the methyl lauroyl acetate enters the feed pipe 5 through the funnel 9. At this time, start the first motor 18. The first bevel gear 19 at the output end of the first motor 18 drives the second bevel gear 20 meshing with it to rotate, thereby causing the rotating shaft 7 to rotate under the support of the limiting frame 6. The rotating shaft 7 drives the agitator 8 to rotate, which crushes the larger particles of methyl lauroyl acetate entering the feed pipe 5, making the particle size of the methyl lauroyl acetate more uniform. Then, the methyl lauroyl acetate smoothly enters the reactor body 1. Next, start the second motor 25 on the fixed frame 24. The second motor 25 drives the agitator through the flange. Rotating rod 31 causes stirring blade 32, connecting rod 33, and scraper 34 to move together. Stirring blade 32 stirs methyl lauroyl acetate in the reactor, ensuring thorough mixing and promoting the chemical reaction. As the stirring rod 31 rotates, scraper 34 removes methyl lauroyl acetate adhering to the inner wall of reactor body 1, preventing scaling and ensuring heat transfer and reaction efficiency. If specific additives or auxiliary reagents are required, they can be added to reactor body 1 through addition pipe 4. After the reaction is complete, the second control valve 23 on discharge pipe 22 is opened to discharge the reaction products from the reactor. In addition, the feed pipe 5 can be opened through sealing cover 13 to repair or replace the internal agitation mechanism. Sealing strip 14 and fixing bolt 16 ensure the sealing of sealing cover 13 when closed.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
