Description

Technical Field

[0001] This invention relates to the field of reaction vessel technology, specifically to a reaction vessel for processing o-veratrol. Background Technology

[0002] o-Veratral is a pale yellow to yellow oily liquid with a distinctive odor at room temperature and pressure. Chemically, it consists of a benzene ring, an aldehyde group, and two methoxy groups, with the methoxy groups located in the ortho position of the benzene ring. This unique structure endows it with special chemical activity. In the field of chemical production, o-Veratral is an important organic synthesis intermediate and is widely used in the pharmaceutical, fragrance, and other industries. Its processing requires strict control over the reaction equipment.

[0003] However, the current reactor has a complex internal structure with many hard-to-clean corners and gaps. Veratraldehyde and its intermediate products in the processing can easily adhere to these parts. Over time, this can not only affect the subsequent reaction but also breed impurities and contaminate the product. At the same time, the existing reactor is not designed with ease of maintenance in mind. The internal components are difficult to disassemble, which increases maintenance costs and downtime, and reduces production efficiency. The existing stirring rods and blades of the reactor are usually connected by a variety of complex methods, such as multiple bolts, interference fits, and then welding or riveting. The connection between the stirring rod and the transmission device of the reactor is also relatively complicated. When disassembling the stirring rod, multiple parts of the transmission device need to be removed before the stirring rod can be taken out. This undoubtedly greatly increases the complexity and time consumption of disassembly, resulting in low disassembly and installation efficiency. The reaction during the processing of o-veratrol is usually exothermic. Traditional reaction vessels are not suitable for precise temperature control. During the processing of o-veratrol, the temperature is prone to be too high, which can lead to uncontrolled reaction and an increase in side reactions. Summary of the Invention

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

The rotating structure 2 includes a limiting ring 201 and a fixed ring 202. Two limiting rings 201 and one fixed ring 202 are fixedly connected to the reactor body 1. Two rotating shafts 203 are fixedly connected to the fixed ring 202. A support frame 204 is provided on the outside of the reactor body 1. The rotating shafts 203 are rotatably connected to the support frame 204. A gear 205 is fixedly connected to one of the rotating shafts 203. A fixed seat 206 is fixedly connected to the support frame 204. A first driving member 207 is fixedly connected to the fixed seat 206. A support plate 208 is fixedly connected to the output end of the first driving member 207. A rack 209 is fixedly connected to the support plate 208. The rack 209 meshes with the gear 205. A fixed plate 210 is fixedly connected to the support frame 204. A guide rod 211 is fixedly connected to the fixed plate 210. The guide rod 211 is slidably connected to the rack 209. The fixing structure 3 includes a sliding rod 301 and a sleeve 302. Two sliding rods 301 are slidably connected to the support frame 204, and two sleeves 302 are fixedly connected to the reactor body 1. A plug block 303 is fixedly connected to the sliding rod 301, and the plug block 303 is inserted into the sleeve 302. The cross-section of the sliding rod 301 is an "I" shape. A spring 304 is fixedly connected between the sliding rod 301 and the support frame 204. A rotating block 305 is rotatably connected to the sliding rod 301, and a fixing rod 306 is fixedly connected to the rotating block 305. The support frame 204 is provided with a fixing hole 307. The fixing structure 3, through the cooperation of the sliding rod 301, the plug block 303 and the sleeve 302, and the auxiliary fixing of the rotating block 305 and the fixing rod 306, makes the reactor more stable during operation, reduces shaking and displacement, and ensures the safety and stability of the reaction process. Pulling the sliding rod 301 causes the plug block 303 to move... Then, insert the plug 302 on the reactor body 1, compress the spring 304, and rotate the rotating block 305 on the slide bar 301 to insert the fixing rod 306 into the fixing hole 307 on the support frame 204, so that the plug 303 is always separated from the plug 302. Then, pull the plug 303 on the other side of the reactor body 1 out of the plug 302 according to the same operation, and then start the first driving component 207. The first driving component 207 is preferably a hydraulic rod. The first driving component 207 drives the support plate 208 to move. The rack 209 on the support plate 208 meshes with the gear 205, so that the reactor body 1 rotates around the rotating shaft 203. During this process, the guide rod 211 slides and connects with the rack 209 to ensure that the rack 209 moves smoothly, thereby realizing the precise adjustment of the reactor angle. After the reactor body 1 is rotated to a suitable angle, the first driving component 207 can be turned off.

The design of the water-cooling cavity 401 and spiral heat exchange plates 402 of the water-cooling structure 4 can effectively remove the reaction heat, accurately control the reaction temperature, avoid side reactions caused by temperature fluctuations, and ensure that the o-veratrol processing reaction is carried out in a suitable temperature environment.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7and Figure 8 As shown, the closed structure 5 includes a mounting shaft 501 and a vessel cover 502 rotatably connected to the mounting shaft 501. The mounting shaft 501 is fixedly connected to the reactor body 1, and multiple fixed shafts 503 are rotatably connected to the reactor body 1. A screw 504 is rotatably connected to the fixed shaft 503. A washer 505 is sleeved on the screw 504 and abuts against the vessel cover 502. A nut 506 is threaded onto the screw 504. The design of the closed structure 5, by utilizing the cooperation of the screw 504 and the nut 506, makes it convenient for operators to open and close the vessel cover 502. The operation is simple and efficient, saving time and labor costs. The driving structure 6 includes guide posts 601 and mounting rings 602. Multiple guide posts 601 are fixedly connected to the vessel cover 502, and mounting rings 602 are slidably connected to the multiple guide posts 601. A second driving component 603 is fixedly connected to the mounting rings 602. A fixing sleeve 605 is fixedly connected to the vessel cover 502, and a connecting rod 607 is slidably connected inside the fixing sleeve 605. The output end of the second driving component 603 is fixedly connected to the connecting rod 607. A connecting block 609 with a regular hexagonal cross-section is fixedly connected to the bottom end of the connecting rod 607, facilitating the transmission of the driving force of the second driving component 603 to the stirring structure 7 through the connecting block 609 and the connecting groove 608. A locking ring 6 is fixedly connected to the connecting rod 607. 10. A lifting ring 611 is rotatably connected to the connecting rod 607. The lifting ring 611 abuts against the locking ring 610. A connecting rod 612 is fixedly connected to the lifting ring 611. The connecting rod 612 is fixedly connected to the mounting ring 602. A third driving component 604 is fixedly connected to the reactor cover 502. The output end of the third driving component 604 is fixedly connected to the bottom end of the mounting ring 602. A sealing sleeve 606 is fixedly connected inside the fixing sleeve 605. The connecting rod 607 is slidably connected to the sealing sleeve 606. The driving structure 6 can flexibly control the connection and separation of the stirring rod 702. It can also be used in conjunction with other structures to adjust the working state of the reactor, enhancing the operational convenience and functionality of the reactor and meeting different production needs. The stirring structure 7 includes a mounting base 701 and a stirring rod 702. The mounting base 701 is fixedly connected inside the reactor body 1, and the stirring rod 702 is rotatably connected to the mounting base 701. The stirring rod 702 has a connecting groove 608 with a regular hexagonal cross-section. A connecting block 609 is inserted into the connecting groove 608. Multiple sets of stirring blades 703 are fixedly connected to the stirring rod 702. The stirring rod 702 cooperates with the connecting block 609 and rotates stably under the drive of the driving structure 6. The multiple sets of stirring blades 703 can fully stir the materials, promoting a more complete reaction in the processing of veratraldehyde, improving product quality and production efficiency. Multiple sockets 704 are fixedly connected to the inner wall of the reactor body 1. The base 704 is provided with a mounting groove 705, and a mounting bracket 706 is inserted into the mounting groove 705. The middle part of the mounting bracket 706 is sleeved on the outside of the stirring rod 702, and the stirring rod 702 is rotatably connected to the mounting bracket 706. The third driving component 604 in the drive structure 6 is activated. The third driving component 604 is preferably a hydraulic rod. When the hydraulic rod retracts, its output end pulls the mounting ring 602 downward, thereby driving the second driving component 603 downward. The second driving component 603 is preferably a motor. The connecting rod 607 moves downward, so that the connecting block 609 is accurately inserted into the connecting groove 608 of the stirring rod 702. Then the second driving component is activated, and the second driving component 603 drives the stirring rod 702 to start moving on the mounting base 701. The rotation drives the stirring blade 703 to stir the materials in the reactor, promoting thorough mixing and reaction of the raw materials. When it is necessary to replace or disassemble the stirring rod 702 and stirring blade 703, the connection between the feed pipe and the material conveying pipe on the reactor cover 502 can be disconnected first. Then, rotate the nut 506. After the nut 506 stops pressing on the reactor cover 502, the gasket 505 moves accordingly, releasing the clamping force on the reactor cover 502. Then, make the screw 504 rotate around the fixed shaft 503. Next, start the third drive component 604, which in turn drives the mounting ring 602 to rise. The mounting ring 602 drives the connecting rod 612 to rise. The connecting rod 612 drives the lifting ring 611 to rise. The lifting ring 611 drives the locking ring 610 and the connecting rod 607 to rise. After the connecting rod 607 drives the connecting block 609 to no longer be inserted into the connecting groove 608 on the stirring rod 702, the vessel cover 502 is rotated around the mounting shaft 501 to open it. Then, the reactor body 1 is rotated through the rotating structure 2. After rotation, the operator can easily see the condition of the parts inside the reactor body 1 and also easily clean the inner cavity of the reactor body 1. When disassembling the stirring rod 702 and the stirring blade 703, the mounting bracket 706 can be pulled out from the mounting groove 705 on the socket 704 first. After the mounting bracket 706 does not obstruct the stirring rod 702 and the stirring blade 703, the stirring rod 702 can be pulled out from the mounting base 701 for replacement. The operation is simple and improves the disassembly efficiency of the stirring rod 702 and the stirring blade 703.

[0025] When using this invention, firstly, after confirming that there are no abnormalities in the feed pipe, the raw materials required for the processing of o-veratrol are added to the reactor body 1 through the two feed pipes on the reactor lid 502. When adding the materials, the addition speed and amount must be carefully controlled to avoid splashing due to excessively rapid addition or inaccurate addition affecting the reaction effect. For some special materials, it may be necessary to add them in a specific order. During the reaction, the third driving component 604 in the drive structure 6 is activated. The third driving component 604 is preferably a hydraulic rod. When the hydraulic rod retracts, its output end pulls the mounting ring 602 downwards, thereby driving... The second driving component 603 moves downward. Preferably, the second driving component 603 is a motor. The connecting rod 607 moves downward, causing the connecting block 609 to precisely insert into the connecting groove 608 of the stirring rod 702. Then, the second driving component 603 is activated, driving the stirring rod 702 to rotate on the mounting base 701, which in turn drives the stirring blade 703 to stir the materials in the reactor, promoting thorough mixing and reaction of the raw materials. When it is necessary to replace or disassemble the stirring rod 702 and the stirring blade 703, the connection between the feed pipe and the material conveying pipe on the reactor cover 502 can be disconnected first, and then the nut 50 can be rotated. 6. After nut 506 stops pressing on lid 502, gasket 505 moves accordingly, releasing the clamping force on lid 502. Then, screw 504 rotates around fixed shaft 503. Next, third drive component 604 is activated, which in turn drives mounting ring 602 to rise. Mounting ring 602 drives connecting rod 612 to rise. Connecting rod 612 drives lifting ring 611 to rise. Lifting ring 611 drives locking ring 610 and connecting rod 607 to rise. After connecting rod 607 causes connecting block 609 to no longer engage with connecting groove 608 on stirring rod 702, lid 5 rotates around mounting shaft 501. 02. Open it, and then rotate the reactor body 1 by rotating the structure 2. After rotation, the operator can easily see the condition of the parts inside the reactor body 1, and at the same time, it is easy to clean the inner cavity of the reactor body 1. When disassembling the stirring rod 702 and the stirring blade 703, the mounting bracket 706 can be pulled out from the mounting slot 705 on the socket 704 first. After the mounting bracket 706 does not block the stirring rod 702 and the stirring blade 703, the stirring rod 702 can be pulled out from the mounting base 701 for replacement. The operation is simple and improves the disassembly efficiency of the stirring rod 702 and the stirring blade 703. Then, when the reactants inside the reactor body 1 are reacting, cooling water can be introduced into the water inlet pipe 403 of the water-cooling structure 4. Under the action of the spiral heat exchange plate 402 in the water-cooling chamber 401, the cooling water efficiently removes the heat generated by the reaction. The water that removes the heat is discharged from the water outlet pipe 404, thereby precisely controlling the reaction temperature and preventing the temperature from being too high and causing side reactions. Finally, when it is necessary to inspect or clean the reactor body 1, the reactor body 1 can be rotated by rotating structure 2. When rotating the reactor body 1, it is necessary to pull slide rod 301. Slide rod 301 causes the insert block 303 to no longer be inserted into the insert sleeve 302 on the reactor body 1, and spring 304 is compressed. Then, rotate the rotating block 305 on slide rod 301 to insert the fixing rod 306 into the fixing hole 307 on support frame 204, so that the insert block 303 is always separated from the insert sleeve 302. Then, pull out the insert block 303 on the other side of reactor body 1 by the same operation. Insert sleeve 302, and then start the first driving component 207. The first driving component 207 is preferably a hydraulic rod. The first driving component 207 drives the support plate 208 to move. The rack 209 on the support plate 208 meshes with the gear 205, so that the reactor body 1 rotates around the rotating shaft 203. During this process, the guide rod 211 is slidably connected with the rack 209 to ensure that the rack 209 moves smoothly, thereby realizing the precise adjustment of the reactor angle. After the reactor body 1 is rotated to a suitable angle, the first driving component 207 can be turned off. At this time, it is convenient to inspect and maintain the internal components of the reactor body 1.
