Description

Technical Field

[0001] This invention belongs to the field of aluminum alkoxide synthesis technology, and specifically relates to a reaction vessel for aluminum alkoxide synthesis. Background Technology

[0002] Aluminum alkoxides have very strong hygroscopic properties and are used as desiccants. They decompose in water to form aluminum hydroxide, which, upon calcination, yields alumina with low impurity content. Therefore, aluminum alkoxides have become a major raw material source for alumina production. Typically, aluminum alkoxides are produced by reacting metallic aluminum with the corresponding alcohol in the presence of a catalyst. The reaction of aluminum with alcohol to form aluminum alkoxides is exothermic. Currently, aluminum alkoxide synthesis employs a batch synthesis method, which cannot achieve continuous production, is difficult to operate, and has low capacity.

[0003] Chinese patent CN222829596U discloses an aluminum alkoxide production apparatus, including a reactor. The reactor contains: a solid silo with a grid-like bottom support wall; a raw material inlet pipe connecting to the reactor from below the solid silo; a first inlet assembly positioned above the solid silo; a vent pipe passing through the solid silo from bottom to top; and a discharge pipe connected to the first and second inlet assemblies via pipelines. This apparatus avoids boiling over during the synthesis process and offers advantages such as simple operation and safe controllability.

[0004] The synthesis of aluminum alkoxides generates a large amount of heat, which can lead to explosive boiling. Existing technologies typically employ two methods to address this: one is to cool the reaction using cooling water to control the reaction rate; the other is to separate the organic alcohol and high-purity aluminum blocks within the reactor using a solid silo, controlling the contact area between the solid and liquid reactants to ensure a uniform and gentle synthesis reaction, thus preventing explosive boiling. However, cooling with water consumes a large amount of water and cannot fundamentally control the reaction rate; while separating the aluminum blocks from the organic alcohol may cause aluminum oxide to reform on the aluminum block surface, which not only reduces the reaction rate but also affects product purity. Summary of the Invention

[0005] The purpose of this invention is to provide a reaction vessel for aluminum alkoxide synthesis, so as to solve the problem that the existing technology cannot control the reaction rate of aluminum alkoxide synthesis, thus making it difficult to achieve continuous aluminum alkoxide synthesis.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a reactor for the synthesis of aluminum alkoxide, comprising a synthesis reactor, a solid material silo assembly, and a partition. The synthesis reactor includes a reactor body and a reactor cover located at the top of the reactor body. The partition is installed at the bottom inner part of the reactor body and extends along the axial direction of the reactor body to divide the lower middle part of the reactor body into two chambers.

[0007] The solid material silo assembly includes two support blocks fixedly installed on the top sides of the partition, a drive shaft, and a drive mechanism. The two ends of the drive shaft are rotatably mounted on the two support blocks. Aluminum frames are provided on both sides of the outer wall of the drive shaft. Connecting rods are connected between the two ends of the aluminum frames and the outer wall of the drive shaft. One end of the connecting rod is hinged to the aluminum frame, and the other end of the connecting rod is fixedly connected to the outer wall of the drive shaft. The drive mechanism is installed on the lid of the vessel and is used to drive the drive shaft to rotate.

[0008] The beneficial effect of this invention is that by setting up a solid material silo assembly, a partition divides the lower middle part of the reactor body into two chambers. During the aluminum alkoxide synthesis reaction, a pre-treated aluminum block is placed inside an aluminum frame. A drive mechanism rotates the drive shaft, moving the aluminum frame into one of the chambers, allowing the aluminum frame to react with the reaction liquid in that chamber. When the temperature of the reaction liquid reaches a preset critical value, the drive mechanism rotates the drive shaft, moving the aluminum frame into the other chamber for further reaction. Simultaneously, the reaction liquid in the chamber not participating in the reaction begins to cool down. This solution controls the aluminum frame to move back and forth between the two chambers. When one chamber participates in the aluminum alkoxide synthesis reaction, the reaction liquid in the other chamber cools down, thus allowing the aluminum alkoxide synthesis reaction to proceed continuously without waiting for the reaction liquid temperature to decrease, thereby improving reaction efficiency.

[0009] The drive mechanism includes a support frame installed at the top center of the vessel lid and a transmission component installed at the top center of the partition plate. A drive motor is fixedly installed on the top of the support frame, and a coaxial drive shaft is rotatably installed inside the vessel body. The top of the drive shaft rotates through the vessel lid and is connected to the output shaft of the drive motor. The bottom of the drive shaft is connected to the transmission shaft through the transmission component.

[0010] The transmission component includes a housing, a first bevel gear, and a second bevel gear. The bottom end of the drive shaft extends into the housing and is rotatably connected to it. The drive shaft rotates through the housing. The first bevel gear and the second bevel gear mesh with each other and are both located inside the housing. The first bevel gear is fixedly installed at the bottom end of the drive shaft, and the second bevel gear is fixedly sleeved on the outer wall of the drive shaft.

[0011] Multiple through slots extending along their length are provided on the front and rear outer walls of the aluminum frame, and the through slots penetrate the frame wall of the aluminum frame. Multiple through holes are provided on the bottom wall of the aluminum frame, and the through holes penetrate the bottom wall of the aluminum frame.

[0012] The effect is that the design of the through grooves and through holes allows the aluminum block to be fully agitated and mixed inside the aluminum frame, while the reaction liquid continuously washes the surface of the aluminum block, effectively inhibiting the regeneration of the oxide layer on the surface of the aluminum block and promoting the uniform diffusion of heat. This synergistic effect of the structure ensures that the solid-liquid reaction proceeds uniformly and gently, avoiding the phenomenon of boiling over caused by local overheating.

[0013] The length of the connecting rod is greater than the height of the aluminum frame. A fixing sleeve is fixedly installed at the end of the connecting rod away from the aluminum frame. The fixing sleeve is fixedly fitted onto the outer wall of the drive shaft, and the connecting rod is fixedly connected to the drive shaft through the fixing sleeve.

[0014] The effect is that the length of the connecting rod is greater than the height of the aluminum frame. This dimensional relationship is designed to ensure that the connecting rod has enough room to move during the rotation of the aluminum frame, thereby avoiding physical interference or collision between the two.

[0015] The partition has an internal cavity. Cooling water outlet pipes are fixedly installed at both ends of the top of the partition. One end of the cooling water outlet pipe is connected to the cavity, and the other end of the cooling water outlet pipe passes through the vessel body and extends out of the synthesis reactor. Cooling water inlet pipe is fixedly installed in the middle of the bottom of the partition. One end of the cooling water inlet pipe is connected to the cavity, and the other end of the cooling water inlet pipe passes through the vessel body and extends out of the synthesis reactor.

[0016] The effect is that when the aluminum alkoxide synthesis reaction proceeds inside the reactor and generates a large amount of heat, cooling water is introduced into the cavity inside the baffle through the cooling water inlet pipe at the bottom. As the cooling water flows within the cavity, it directly absorbs the heat generated by the baffle and the surrounding reaction area. Because hot water is less dense than cold water, the heated cooling water naturally rises and is discharged from the synthesis reactor through the cooling water outlet pipes at both ends of the baffle, forming a highly efficient cooling cycle. This allows the baffle to continuously remove reaction heat, effectively controlling the temperature of the two chambers inside the reactor.

[0017] Drainage pipes are fixedly installed on both sides of the bottom of the vessel. The two drainage pipes are connected to two chambers inside the vessel and are used to drain the liquid that has completed the reaction inside the vessel.

[0018] The top of the vessel lid is equipped with a discharge port, and two liquid addition pipes are fixedly installed on both sides of the top of the vessel lid. The two liquid addition pipes are connected to two chambers inside the vessel body. The discharge port is used to add solid materials into the aluminum frame, and the two liquid addition pipes are used to add reaction liquids into the two chambers inside the vessel body.

[0019] Multiple support plates are fixedly installed on the outer wall of the vessel body, evenly distributed along its circumference, for supporting and fixing the vessel body during installation.

[0020] Temperature sensors are installed in both chambers inside the vessel.

[0021] The effect is that, since the aluminum alkoxide synthesis reaction is exothermic, the temperature inside the chamber will rise. The temperature sensor can sense and measure the actual reaction temperature of its chamber in real time and directly. When the temperature rises to the set critical value, it can promptly control the aluminum frame to move to another chamber for the reaction.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] By incorporating a solid material silo assembly, a partition divides the lower middle section of the reactor body into two chambers. During the aluminum alkoxide synthesis reaction, a pre-treated aluminum block is placed inside an aluminum frame. A drive mechanism rotates the drive shaft, moving the aluminum frame into one of the chambers, where it reacts with the reaction liquid. When the reaction liquid temperature reaches a pre-set critical value, the drive mechanism rotates the drive shaft again, moving the aluminum frame into the other chamber for further reaction. Simultaneously, the reaction liquid in the unreacted chamber begins to cool down. This design controls the aluminum frame's back-and-forth movement between the two chambers, allowing the reaction to proceed continuously without waiting for the reaction liquid temperature to drop, thus improving reaction efficiency.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Please see Figures 1-7 The present invention provides the following technical solution: a reactor for the synthesis of aluminum alkoxides, comprising a synthesis reactor 1, a solid material silo assembly 2, and a partition 3. The partition 3 is installed at the inner bottom of the reactor body 11 and extends along the axial direction of the reactor body 11 to divide the lower middle part of the reactor body 11 into two chambers. As a preferred implementation, the partition 3 can be a vertical plate-like structure fixed inside the reactor body 11 and fixed to the inner wall of the reactor body 11 by welding or bolting.

[0034] refer to Figures 1-3 As shown, the synthesis reactor 1 consists of a reactor body 11 and a reactor lid 12 located on top of it. The reactor body 11 is made of corrosion-resistant material and can withstand the temperature and pressure generated during the aluminum alkoxide synthesis reaction, providing a suitable environment for the reaction. The reactor lid 12 is used to seal the reactor body 11, effectively preventing leakage of reactants or products. The reactor lid 12 is designed to be detachable, using a flange connection and bolt tightening to achieve a reliable seal, which facilitates equipment maintenance and cleaning.

[0035] Drain pipes 14 are fixedly installed on both sides of the bottom of the vessel body 11. The fixing method can include welding, flange connection, or threaded connection. This design prefers welding, which provides stronger structural integrity and sealing, and is suitable for high-pressure or high-temperature environments. The two drain pipes 14 are respectively connected to two chambers inside the vessel body 11, used to drain the liquid that has completed the reaction inside the vessel body 11. The draining process can be achieved by the pressure difference inside the vessel body 11, the suction of an external pump, or simple gravity flow. The drain pipes 14 are pipes used to export the liquid medium inside the vessel body 11, and they can be made of corrosion-resistant metal materials.

[0036] The top of the vessel lid 12 is provided with a discharge port 121. Both sides of the top of the vessel lid 12 are fixedly installed with liquid addition pipes 122. The two liquid addition pipes 122 are respectively connected to two chambers inside the vessel body 11. The discharge port 121 is used to add solid materials into the vessel body 11, and the two liquid addition pipes 122 are used to add reaction liquids into the two chambers inside the vessel body 11.

[0037] Multiple support plates 13 are fixedly installed on the outer wall of the vessel body 11, which are evenly distributed along its circumference, for supporting and fixing the vessel body 11 during installation.

[0038] Temperature sensors 15 are installed in both chambers inside the vessel body 11 to detect the temperature of the reaction liquid in real time.

[0039] refer to Figure 2 , Figures 4-6As shown, the solids silo assembly 2 is used to store and control the contact between solid reactants and liquid reactants. This assembly achieves dynamic dispensing or contact adjustment of solid materials through mechanical movement. The solids silo assembly 2 includes a support block 25, a drive shaft 26, an aluminum frame 27, a connecting rod 28, and a drive mechanism.

[0040] There are two support blocks 25, which are symmetrically fixedly installed on both sides of the top of the partition 3. The support blocks 25 can be fixed to the top of the partition 3 by bolts or welding.

[0041] The two ends of the drive shaft 26 are rotatably mounted on two support blocks 25 respectively. The rotatable mounting of the drive shaft 26 can be achieved by setting bearing seats on the support blocks 25 and installing rolling bearings to ensure the smoothness and low friction of the drive shaft 26 during rotation.

[0042] There are at least two aluminum frames 27, and multiple aluminum frames 27 are evenly distributed along the axial direction of the drive shaft 26. The aluminum frames 27 can be designed as a mesh or porous structure to ensure that the liquid reactant can fully penetrate and contact the internal aluminum block. In this embodiment, multiple through grooves 271 extending along their length are provided on the front and rear outer walls of the aluminum frames 27, and the through grooves 271 penetrate the frame walls of the aluminum frames 27. Multiple through holes 272 are provided on the bottom wall of the aluminum frames 27, and the through holes 272 penetrate the bottom wall of the aluminum frames 27. In other embodiments, the aluminum frames 27 can be welded from metal mesh or formed by bending perforated sheet metal.

[0043] These through-slots 271 are designed to increase the contact area and flow path between the interior and exterior reaction liquids of the aluminum frame 27. This can be achieved, but is not limited to: forming a series of rectangular, elliptical, or slit-like openings on the sidewall of the aluminum frame 27 through machining; or forming these openings directly during the manufacturing process of the aluminum frame 27. Regarding the through-slots 271 penetrating the wall of the aluminum frame 27, this feature clearly indicates that the through-slots 271 completely penetrate the wall thickness of the aluminum frame 27, thereby ensuring that liquid and solid particles can freely enter and exit the interior of the aluminum frame 27. This through-hole design ensures sufficient exchange of internal and external fluids, avoiding fluid stagnation or blockage that may occur with blind holes or partial openings. This can be achieved, but is not limited to: using precision machining methods such as drilling, laser cutting, or wire cutting to ensure the complete penetration of the through-slots 271; or considering its through-hole structure during mold design and achieving it through integral molding. Regarding the multiple through holes 272 formed on the bottom wall of the aluminum frame 27, these through holes 272 refer to multiple openings provided at the bottom of the aluminum frame 27. The main function of these through holes 272 is to facilitate the discharge of reaction products or reaction liquids, prevent solid particles from accumulating at the bottom, and further enhance fluid circulation. These through holes can be achieved, but are not limited to: forming circular, square, or polygonal holes on the bottom wall of the aluminum frame 27 by drilling, stamping, or other methods; or pre-reserving these holes during the casting or forming of the bottom wall.

[0044] Both ends of the aluminum frame 27 are connected to the outer wall of the drive shaft 26 via connecting rods 28. The length of the connecting rod 28 is greater than the height of the aluminum frame 27. One end of the connecting rod 28 is hinged to the aluminum frame 27, and this hinge can be achieved through a pin connection. The other end of the connecting rod 28 is fixedly fitted with a fixing sleeve 281, which is fixedly sleeved on the outer wall of the drive shaft 26. The fixing sleeve 281 can be fixedly sleeved on the outer wall of the drive shaft 26 by means of key connection, spline connection, expansion sleeve connection, or bolt fastening. The connecting rod 28 is fixedly connected to the drive shaft 26 through the fixing sleeve 281. In other embodiments, the fixed connection between the connecting rod 28 and the drive shaft 26 can also be achieved by welding, key connection, or bolt fastening.

[0045] The length of the connecting rod 28 is greater than the height of the aluminum frame 27. This dimensional relationship is designed to ensure that the connecting rod 28 has sufficient room to move during the rotation of the aluminum frame 27, thereby avoiding physical interference or collision between the two. This design can be achieved by precisely measuring and designing the length of the connecting rod 28 to maintain a safe distance from the edge of the aluminum frame 27 throughout its entire range of rotation.

[0046] The drive mechanism moves the aluminum frame 27 to react with the organic alcohol in two separate chambers. When the temperature in one chamber rises to a critical value, the drive mechanism moves the aluminum frame 27 to the other chamber to react with the organic alcohol. After the reaction in the first chamber is complete, the temperature is allowed to cool down. This allows the device to switch to the other chamber to continue the reaction when the temperature rises during the reaction process, without waiting for the reaction liquid temperature to drop, thus improving reaction efficiency. While the aluminum frame 27, carrying the aluminum block, reacts in the chamber, the drive mechanism causes the transmission shaft 26 to swing slightly, causing the aluminum frame 27 to oscillate within the organic alcohol, improving the fluidity of the organic alcohol and ensuring uniform heat distribution. Under the oscillation action of the aluminum frame 27, the organic alcohol can make full contact with the aluminum block.

[0047] The drive mechanism, mounted on the vessel lid 12, is a device used to provide power to drive the transmission shaft 26 to rotate, thereby achieving precise control over the contact process of solid materials. The drive mechanism includes a support frame 21 mounted at the center of the top of the vessel lid 12 and a transmission component 24 mounted at the center of the top of the partition plate 3. A drive motor 22 is fixedly mounted on the top of the support frame 21. A drive shaft 23, coaxial with the support frame 21, is rotatably mounted inside the vessel body 11. The top of the drive shaft 23 rotates through the vessel lid 12 and is connected to the output shaft of the drive motor 22. The bottom of the drive shaft 23 is connected to the transmission shaft 26 via the transmission component 24.

[0048] The support frame 21 is a structural component used to fix and support the drive motor 22. It is installed at the top center of the vessel cover 12 and is designed to provide a stable base for the entire drive system and ensure that the drive motor 22 is accurately and centrally mounted to reduce vibration and off-center load during operation. The support frame 21 can take various structural forms, such as a frame structure welded from metal sheets or an integral support formed from castings.

[0049] The drive motor 22 is the core component that provides rotational power, and it is fixedly mounted on top of the support frame 21. The drive motor 22 can be an AC motor, DC motor, stepper motor, or servo motor, etc., selected according to the required torque, speed accuracy, and control requirements. By fixing it to the support frame 21, the stability and reliability of the power output can be ensured.

[0050] The drive shaft 23 is a key transmission component connecting the drive motor 22 and the transmission element 24. It is rotatably mounted inside the vessel body 11 and remains coaxial with the vessel body 11. The drive shaft 23 is typically made of a high-strength metal material, such as stainless steel. The transmission connection between the drive shaft 23 and the output shaft of the drive motor 22 can take various forms, such as a rigid coupling, a flexible coupling, or a gear coupling.

[0051] Transmission component 24 is a mechanical part used to transmit power and motion between drive shaft 23 and drive shaft 26. Its main function is to realize the conversion of speed and torque, or to change the transmission direction. Transmission component 24 includes housing 241, first bevel gear 242 and second bevel gear 243. The bottom end of drive shaft 23 extends into the interior of housing 241 and is rotatably connected to it. Drive shaft 26 rotatably passes through housing 241. First bevel gear 242 and second bevel gear 243 mesh with each other and are both located inside housing 241. First bevel gear 242 is fixedly installed at the bottom end of drive shaft 23. The fixed installation can be achieved by interference fit, key connection, spline connection or bolt fixation, etc., to ensure that the two form a solid whole. Second bevel gear 243 is fixedly sleeved on the outer wall of drive shaft 26. Similar to the fixing method of first bevel gear 242, second bevel gear 243 can also be firmly fixedly connected to drive shaft 26 by interference fit, key connection, spline connection or bolt fixation. The first bevel gear 242 and the second bevel gear 243 are key components for realizing power transmission between the intersecting shafts. They can change the direction of rotation of the drive shaft 23 and transmit it to the transmission shaft 26. The bevel gears can be spur bevel gears or spiral bevel gears.

[0052] The present invention provides a stable support for the entire drive system by fixing the drive motor 22 to the support frame 21 at the top center of the vessel lid 12, effectively avoiding transmission instability caused by vibration or off-center load during operation. The drive shaft 23 is rotatably mounted inside the vessel body 11 and coaxial with it, ensuring smooth power transmission and reducing additional stress and wear caused by axis deviation. The top of the drive shaft 23 is directly connected to the output shaft of the drive motor 22, realizing efficient power transmission from the motor to the drive shaft 23. Subsequently, the bottom of the drive shaft 23 is connected to the transmission shaft 26 through the transmission component 24 installed at the top center of the partition 3, so that the driving force can be accurately transmitted to the transmission shaft 26, thereby driving the aluminum frame 27 in the solid material hopper assembly 2 to rotate. This not only ensures the effective transmission of driving force, but also significantly improves the installation stability, operational reliability, and maintenance convenience of the entire drive mechanism.

[0053] The drive motor 22 drives the drive shaft 23 to rotate. The bottom end of the drive shaft 23 extends into the housing 241 of the transmission component 24 and is fixedly connected to the first bevel gear 242 inside the housing 241. The first bevel gear 242 meshes with the second bevel gear 243, transmitting the rotational motion and power of the drive shaft 23 to the second bevel gear 243 and changing the transmission direction. The second bevel gear 243 is fixedly sleeved on the outer wall of the transmission shaft 26, thereby driving the transmission shaft 26 to rotate. The rotation of the transmission shaft 26 passes through the housing 241, outputting rotational power, which in turn drives the aluminum frame 27 to rotate.

[0054] refer to Figure 7 As shown, the partition 3 has an internal cavity, which is a pre-reserved space within the partition 3 to accommodate the flow of cooling medium. Its function is to provide a channel for the flow of cooling water, thereby regulating the temperature of the partition 3 and the surrounding reaction zone. This cavity can be achieved by integrally forming an internal channel during the casting or molding of the partition 3, or by welding or bonding two plates together to form a closed space in the middle as a flow channel, or by drilling or milling flow channels inside the solid partition 3.

[0055] Cooling water outlet pipes 31 are fixedly installed at both ends of the top of the partition plate 3. One end of the cooling water outlet pipe 31 is connected to the cavity, and the other end of the cooling water outlet pipe 31 passes through the vessel body 11 and extends out of the synthesis reactor 1. This cooling water outlet pipe 31 is used to drain the heated cooling water from the cavity, ensuring that the cooling water can be smoothly discharged, forming a circulation and carrying away heat. The cooling water outlet pipe 31 can be fixedly installed on the top of the partition plate 3 by means of threaded connection, flange connection, or welding, and is made of corrosion-resistant and high-temperature-resistant metal materials, such as stainless steel or alloy steel. The connection between one end of the cooling water outlet pipe 31 and the cavity aims to establish a fluid channel between the cavity and the cooling water outlet pipe 31, allowing cooling water to enter the cooling water outlet pipe 31 from the cavity. This can be achieved by opening holes at corresponding positions on the top of the partition plate 3 and inserting or welding the end of the cooling water outlet pipe 31 into the holes, supplemented by sealing gaskets or welding to ensure a tight connection. The other end of the cooling water outlet pipe 31 passes through the vessel body 11 and extends out of the synthesis reactor 1. Its purpose is to lead the cooling water out of the reactor so as to connect to an external cooling circulation system. When the cooling water outlet pipe 31 passes through the wall of the vessel body 11, it can be sealed by means of sleeve welding or flange sealing to ensure the sealing and strength of the vessel body 11. The part extending out of the synthesis reactor 1 is usually connected to an external cooling tower, heat exchanger or cooling water pump.

[0056] A cooling water inlet pipe 32 is fixedly installed at the bottom center of the partition 3. One end of the cooling water inlet pipe 32 communicates with the cavity, and the other end of the cooling water inlet pipe 32 passes through the vessel body 11 and extends out of the synthesis reactor 1. This cooling water inlet pipe 32 is used to introduce external cooling water into the cavity, and its function is to introduce the cooling medium into the interior of the partition 3 to start the cooling cycle. The cooling water inlet pipe 32 can be fixedly installed at the bottom center of the partition 3 by means of threaded connection, flange connection, or welding, and is made of corrosion-resistant and high-temperature resistant metal material. One end of the cooling water inlet pipe 32 communicates with the cavity to establish a fluid channel between the cavity and the cooling water inlet pipe 32, so that cooling water can enter the cavity from the cooling water inlet pipe 32. This can be achieved by making a hole at the corresponding position at the bottom of the partition 3, inserting or welding the end of the cooling water inlet pipe 32 into the hole, and using a sealing gasket or welding method to ensure the sealing of the connection. The other end of the cooling water inlet pipe 32 passes through the vessel body 11 and extends out of the synthesis reactor 1. Its purpose is to introduce external cooling water into the reactor so as to connect to the external cooling circulation system. When the cooling water inlet pipe 32 passes through the wall of the vessel body 11, it can be sealed by means of sleeve welding or flange sealing to ensure the sealing and strength of the vessel body 11. The part extending out of the synthesis reactor 1 is usually connected to an external cooling water pump or cooling water supply system.

[0057] The present invention integrates a cooling system within the partition 3, making it not only a structure separating the two chambers inside the reactor body 11, but also an active temperature control unit. Specifically, when the aluminum alkoxide synthesis reaction proceeds inside the reactor body 11 and generates a large amount of heat, cooling water is introduced into the cavity inside the partition 3 through the cooling water inlet pipe 32 at the bottom. As the cooling water flows within the cavity, it directly absorbs the heat generated by the partition 3 and the surrounding reaction area. Since hot water is less dense than cold water, the heated cooling water naturally rises and is discharged from the synthesis reactor 1 through the cooling water outlet pipes 31 at both ends of the top of the partition 3, forming an efficient cooling cycle. This design allows the partition 3 to continuously remove reaction heat, effectively controlling the temperature of the two chambers inside the reactor body 11. By integrating the cooling function into the partition 3, this solution fully utilizes the space of the partition 3 as a separating structure, enabling it to perform the crucial temperature control task while achieving physical isolation.

[0058] The implementation principle of this invention is as follows: During the synthesis of aluminum alkoxide, an aluminum block is placed into an aluminum frame 27 through a discharge port 121. The drive motor 22 is started, causing the drive shaft 23 to rotate. The drive shaft 23, through a transmission component 24, drives a transmission shaft 26 to rotate. The transmission shaft 26, through a connecting rod 28, moves the aluminum frame 27 into one of the chambers. At this time, the reaction liquid enters the aluminum frame 27 through a channel 271 and reacts with the aluminum block. Simultaneously, the drive motor 22, through the drive shaft 23 and the transmission component 24, drives the transmission shaft 26 to reciprocate at a certain angle, thereby causing the aluminum frame 27 to vibrate, improving the fluidity of the organic alcohol and ensuring uniform heat distribution. Under the oscillation action of the aluminum frame 27, the organic alcohol and the aluminum block are in full contact.

[0059] When the temperature sensor 15 of the chamber detects that the temperature of the reaction liquid in the chamber has risen to a critical value, the drive motor 22 drives the transmission shaft 26 to rotate through the drive shaft 23 and the transmission component 24. At this time, the transmission shaft 26 drives the aluminum frame 27 to move rapidly to another chamber for reaction. Simultaneously, circulating cooling water is discharged into the cavity of the partition 3 through the cooling water inlet pipe 32 at the bottom of the synthesis reactor 1. When the cavity of the partition 3 is full of cooling water, the cooling water is discharged through the cooling water outlet pipes 31 on both sides of the partition 3. During this process, the cooling water exchanges heat with the reaction liquid that has reached the critical temperature, thereby removing heat and cooling the reaction liquid. By controlling the aluminum frame 27 to move back and forth between the two chambers, when the aluminum frame 27 is reacting in one chamber, the other chamber is being cooled. Therefore, this scheme eliminates the need to wait for the temperature of the reaction liquid to drop, realizing the continuous progress of the aluminum alkoxide synthesis reaction and fundamentally controlling the reaction rate.

[0060] Although embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention.
