Description

Technical Field

[0001] This utility model relates to the field of preparation vessel technology, specifically a preparation vessel for preparing a diketone dehydrogenation catalyst. Background Technology

[0002] The dimerketone dehydrogenation reaction refers to the reaction between a dimerketone and an aromatic amine under the catalysis of a catalyst, such as cerium oxide. In the reaction, the dimerketone undergoes dehydrogenation under the action of the catalyst to generate benzoquinone, which then reacts with the aromatic amine to obtain the corresponding o-aromatic aminophenol. When preparing the catalyst cerium oxide, it is often necessary to mix the aqueous solution containing cerium source with glacial acetic acid and ethylene glycol evenly and react under normal pressure to obtain cerium oxide. A preparation vessel is often used for mixing. However, in the existing preparation vessels, the raw materials are usually in a static state in the vessel body during use, resulting in poor fluidity. Furthermore, most existing preparation vessels do not have the function of fully stirring the raw materials, resulting in poor mixing effect and low preparation efficiency. Therefore, a preparation vessel for preparing dimerketone dehydrogenation catalyst is proposed. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides a preparation vessel for preparing a diketone dehydrogenation catalyst, which has the following beneficial effects:

[0014] 1. The preparation vessel for the preparation of the diketone dehydrogenation catalyst is driven by a drive motor to rotate a worm gear, which in turn drives the mounting shaft and turntable to rotate via a worm wheel. During the rotation of the turntable, the moving plate and the entire vessel body move back and forth through a lever and a traction frame. By swaying the vessel body left and right, the flowability of the raw materials in the vessel body is improved, thereby promoting the mixing of the raw materials and improving the preparation efficiency.

[0015] 2. The preparation vessel for the diketone dehydrogenation catalyst uses a servo motor to drive the stirring shaft and stirring blades to rotate, thereby mixing the raw materials inside the vessel. Simultaneously, a dual-axis servo motor drives two driving bevel gears to rotate, which in turn drive two threaded sleeves to rotate. During rotation, the threaded sleeves move two threaded rods upwards, which in turn move the mounting plate, servo motor, stirring shaft, and stirring blades upwards as a whole. Then, the dual-axis servo motor rotates in the opposite direction, causing the two threaded sleeves to rotate in the opposite direction. During this rotation, the threaded sleeves move the two threaded rods, mounting plate, stirring shaft, and stirring blades downwards as a whole. Then, the dual-axis servo motor rotates forward again, and this cycle repeats, causing the stirring blades to move up and down. This coordinated up-and-down movement of the stirring blades during rotation expands the mixing range, ensuring thorough mixing of the raw materials inside the vessel, ultimately promoting mixing and improving preparation efficiency.

[0023] A partition 11 located below the movable plate 3 is fixedly installed inside the rectangular groove 2. A mounting shaft 12 extending to its bottom and movably connected to the inner bottom wall of the rectangular groove 2 is movably installed on the top of the partition 11.

[0024] A first drive assembly 16 is fixedly installed at the bottom of the partition 11, with one end fixedly connected to the outside of the mounting shaft 12.

A worm wheel 164 located below the partition 11 and meshing with the worm gear 163 is fixedly installed on the outside of the mounting shaft 12.

[0025] Fixing plates 17 are fixedly installed on the top left and right sides of the vessel body 4. Slide grooves 18 are opened on the opposite sides of the two fixing plates 17. An installation plate 19 is movably installed between the two slide grooves 18. A servo motor 20 is fixedly installed on the top of the installation plate 19. The model of the servo motor 20 can be MR-J2S-10A. The output shaft of the servo motor 20 extends to the bottom of the installation plate 19 and a stirring shaft 21 with one end extending into the interior of the vessel body 4 is fixedly installed. The output shaft of the servo motor 20 is rotatably connected to the installation plate 19. A through hole adapted to the stirring shaft 21 is opened on the top of the vessel body 4. Six stirring blades 22 located inside the vessel body 4 are fixedly installed on both the left and right sides of the stirring shaft 21. The six stirring blades 22 on each side are distributed at equal distances.

[0026] Two horizontal plates 23 are fixedly installed between the two fixed plates 17, located above the servo motor 20 and symmetrically distributed vertically. A threaded sleeve 24 extending to the bottom of the bottom horizontal plate 23 is movably installed on the top left and right sides of the top of the top horizontal plate 23. A second mounting hole adapted to the threaded sleeve 24 is opened on the top left and right sides of the two horizontal plates 23. A threaded rod 25 extending to the bottom and fixedly connected to the top of the mounting plate 19 is threaded inside the two threaded sleeves 24.

[0027] A second drive assembly 26 is fixedly installed on the top of the top horizontal plate 23. The left and right ends of the second drive assembly 26 are fixedly connected to the outer sides of the two threaded sleeves 24 respectively. The second drive assembly 26 includes a dual-axis servo motor 261. The dual-axis servo motor 261 located between the two threaded sleeves 24 is fixedly installed on the top of the top horizontal plate 23. The model of the dual-axis servo motor 261 can be HDMF2089050. The output shafts on both the left and right sides of the dual-axis servo motor 261 are fixedly installed with drive bevel gears 262. The outer sides of the two threaded sleeves 24 are fixedly installed with driven bevel gears 263 located above the top horizontal plate 23 and one end of each gear meshes with the two drive bevel gears 262 respectively.

[0028] In use, raw materials such as a cerium-containing aqueous solution, glacial acetic acid, and ethylene glycol are added into the interior of the reactor body 4 through the feed pipe 5. Then, the controller 10 closes the two first solenoid valves 6 and starts the drive motor 161 and servo motor 20. The drive motor 161 drives the worm gear 163 to rotate, which in turn drives the mounting shaft 12 and the turntable 13 to rotate via the worm wheel 164. During rotation, the turntable 13 drives the moving plate 3 and the reactor body 4 to move back and forth left and right via the lever 14 and the traction frame 15. The shaking motion improves the flowability of the raw materials within the vessel 4, thereby promoting mixing and increasing preparation efficiency. The servo motor 20 drives the stirring shaft 21 and stirring blades 22 to rotate, further mixing the raw materials within the vessel 4. Simultaneously, the controller 10 activates the dual-axis servo motor 261 to drive two drive bevel gears 262, which in turn drive two driven bevel gears 263 to rotate two threaded sleeves 24. During rotation, the threaded sleeves 24 move two threaded rods 25 upwards. The mounting plate 19, servo motor 20, stirring shaft 21, and stirring blade 22 are moved upwards as a whole. Then, the dual-axis servo motor 261 rotates in the opposite direction, causing the two threaded sleeves 24 to rotate in the opposite direction. During this rotation, the two threaded sleeves 24 drive the two threaded rods 25, mounting plate 19, stirring shaft 21, and stirring blade 22 to move downwards as a whole. Then, the dual-axis servo motor 261 rotates forward again, and this cycle repeats, causing the stirring blade 22 to move up and down repeatedly. This causes the stirring blade 22 to move up and down during its rotation. The stirring mechanism moves up and down repeatedly to expand the stirring range, thereby enabling thorough stirring of the raw materials within the vessel 4. This further promotes the mixing of the raw materials and improves the preparation efficiency. While mixing, two heating plates 9 can be activated to heat the raw materials. Once the mixing reaction is complete, the drive motor 161, servo motor 20, dual-axis servo motor 261, and two heating plates 9 can be turned off. The two second solenoid valves 8 can then be opened to discharge cerium oxide through the two discharge pipes 7. After cooling the cerium oxide to room temperature, it can be used for the catalytic operation of the diketone dehydrogenation reaction.

[0029] In summary, the preparation vessel for the diketone dehydrogenation catalyst is configured such that the drive motor 161 rotates the worm gear 163, which in turn rotates the mounting shaft 12 and the turntable 13 via the worm wheel 164. During rotation, the turntable 13 moves the moving plate 3 and the vessel body 4 back and forth via the lever 14 and the traction frame 15, improving the flowability of the raw materials within the vessel body 4 and promoting mixing, thus increasing preparation efficiency. Secondly, the servo motor 20 rotates the stirring shaft 21 and stirring blades 22 to mix the raw materials within the vessel body 4. Simultaneously, the dual-axis servo motor 261 rotates two drive bevel gears 262, which in turn rotate two driven bevel gears 263. The rotation of the threaded sleeves 24 causes two threaded rods 25 to move upwards, thereby moving the mounting plate 19 and the servo motor 20. The stirring shaft 21 and stirring blades 22 move upward as a whole, which then causes the dual-axis servo motor 261 to rotate in the opposite direction, thereby driving the two threaded sleeves 24 to rotate in the opposite direction. At this time, the two threaded sleeves 24 will drive the two threaded rods 25, the mounting plate 19, the stirring shaft 21 and the stirring blades 22 to move downward as a whole during the rotation. Then, the dual-axis servo motor 261 will rotate forward again, and so on, driving the stirring blades 22 to move up and down. This allows the stirring blades 22 to move up and down in coordination with the rotation, thereby expanding the stirring range and enabling the raw materials in the vessel 4 to be thoroughly stirred. Ultimately, this further promotes the mixing of raw materials and improves the preparation efficiency. This solves the problems of existing preparation vessels where raw materials are usually in a static state in the vessel and have poor fluidity. Secondly, most existing preparation vessels do not have the function of thoroughly stirring raw materials, resulting in poor mixing effect and low preparation efficiency.
