Technical Field
[0001] This utility model relates to the field of acetate production technology, specifically to an energy-saving reactor for acetate production. Background Technology
[0002] Acetate is a compound formed by replacing the hydroxyl group (-OH) in acetic acid with an alkoxy group (-OR). Its general chemical formula can be represented as CH3COOR, where R represents an alkyl or other organic group attached to the carbonyl carbon atom. A reaction vessel refers to an industrial device specifically used for the esterification reaction of acetic acid and alcohols. The core function of the reaction vessel is to provide a controllable reaction environment for the esterification reaction, thereby producing various acetate compounds efficiently and safely.
[0003] In the current acetate production process, a reactor is usually used to heat and stir the raw materials and catalysts to accelerate the esterification reaction and generate acetate. However, as the raw materials and catalysts are heated, the generated gases are discharged from the reactor, resulting in the loss of heat. This heat loss forces the heater in the reactor to work frequently, which increases energy consumption and waste. To address this, we propose an energy-saving reactor for acetate production.

Detailed Implementation
[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, the energy-saving reactor for acetate production includes a reactor body 1. The top and bottom of the reactor body 1 are respectively provided with an inlet 10 and a outlet 21. A solenoid valve 22 is installed on the outside of the outlet 21. A channel 3 is fixedly connected to the top of the reactor body 1, communicating with the interior of the reactor body 1. A catalyst box 4 is fixedly connected to the top of the channel 3, communicating with the interior of the channel 3. A discharge port 5 is opened on the top of the catalyst box 4. A stirring plate 24 is rotatably connected between the inner walls of the reactor body 1. A stirring assembly is installed on the top of the reactor body 1, which drives the stirring plate 24 to rotate. The outer side of the reactor body 1 is... The vessel is equipped with an exhaust port 18, and a sealing sleeve 19 is slidably connected to the outside of the exhaust port 18. An exhaust assembly is provided on the top of the vessel body 1. The exhaust assembly is used to move the sealing sleeve 19. An exhaust groove 20 is provided on the outside of the sealing sleeve 19. An electromagnetic heater 2 is provided on the outside of the vessel body 1. A sliding groove 6 is provided on one side of the channel 3. A fixing plate 7 is fixedly connected to the top of the vessel body 1. A baffle 8 is slidably connected to one side of the fixing plate 7. The baffle 8 is slidably connected between the inner walls of the sliding groove 6. A material blocking telescopic electric cylinder 9 is fixedly installed on one side of the fixing plate 7. The output end of the material blocking telescopic electric cylinder 9 passes through the fixing plate 7 and is fixedly connected to the baffle 8.
[0023] In the production of acetate, the reactor 1 is first energized, and the raw material is injected into the reactor 1 through the feed inlet 10. Next, the catalyst is injected into the catalyst tank 4 through the discharge port 5. Then, the baffle 8 is moved between the inner walls of the chute 6 by the material-blocking telescopic electric cylinder 9 on one side of the fixed plate 7, thereby precisely controlling the amount of catalyst injected into the channel 3 according to the production requirements. At the same time, the electromagnetic heater 2 heats the raw material and catalyst in the reactor 1, and the stirring assembly drives the stirring plate 24 to rotate between the inner walls of the reactor 1, so as to heat and stir the raw material and catalyst, thereby accelerating the esterification reaction to generate acetate. As the esterification reaction proceeds, gas is generated, and the exhaust assembly drives the sealing sleeve 19 to move outside the exhaust port 18, thereby controlling the exhaust volume of the exhaust groove 20 and avoiding excessive heat loss inside the reactor 1. Then, the acetate is allowed to settle and separate. Since the density of acetate is less than that of water, acetate is located on the upper layer of water. Finally, the discharge port 21 is controlled by the solenoid valve 22 to precisely discharge water and acetate in sequence, thereby improving the efficiency and quality of acetate production.
[0024] like Figures 1-4 As shown, the stirring assembly includes a rotating shaft 23, which is rotatably connected to the top of the inner side of the vessel body 1. The outer side of the rotating shaft 23 is fixedly connected to the stirring plate 24. The top end of the rotating shaft 23 extends to the top of the vessel body 1 and is fixedly connected to a worm gear 11. A vertical plate 12 is fixedly connected to the top of the vessel body 1. A worm 14 is rotatably connected to one side of the vertical plate 12. The worm 14 meshes with the worm gear 11. A stirring motor 13 is fixedly installed on one side of the vertical plate 12. The output end of the stirring motor 13 passes through the vertical plate 12 and is fixedly connected to the worm 14.
[0025] The stirring motor 13 drives the worm gear 14 to rotate on one side of the vertical plate 12. Then, through the meshing action between the worm gear 14 and the worm wheel 11, the worm wheel 11 drives the rotating shaft 23 to rotate, and at the same time drives the stirring plate 24 to rotate between the inner walls of the vessel body 1, thereby improving the efficiency of the reactor.
[0026] like Figures 1-4 As shown, the exhaust assembly includes a mounting plate 16, a connecting plate 17 slidably connected to one side of the mounting plate 16, the bottom of the connecting plate 17 being fixedly connected to the sealing sleeve 19, limit grooves 25 being provided on both sides of the exhaust port 18, and limit blocks 26 being slidably connected between the inner walls of the two limit grooves 25, with the two limit blocks 26 being fixedly connected to both sides inside the sealing sleeve 19 respectively, and an exhaust telescopic electric cylinder 15 being fixedly installed on one side of the mounting plate 16, with the output end of the exhaust telescopic electric cylinder 15 passing through the mounting plate 16 and fixedly connected to the connecting plate 17.
[0027] The exhaust telescopic electric cylinder 15 on one side of the mounting plate 16 drives the connecting plate 17 to move, and the two limiting blocks 26 move between the inner walls of the two limiting grooves 25 respectively, thereby driving the sealing sleeve 19 to move outside the exhaust port 18, thus improving the energy efficiency of the reactor.
[0028] This utility model provides an energy-saving reactor for acetate production. The specific working principle is as follows: During acetate production, the reactor body 1 is first energized, and then the raw material is injected into the reactor body 1 through the feed inlet 10. Next, the catalyst is injected into the catalyst tank 4 through the discharge port 5. Subsequently, the baffle 8 moves between the inner walls of the chute 6 via the material-blocking telescopic electric cylinder 9 on one side of the fixed plate 7, thereby precisely controlling the amount of catalyst injected into the channel 3 according to production requirements. Simultaneously, the electromagnetic heater 2 heats the raw material and catalyst in the reactor body 1. At the same time, the stirring motor 13 drives the worm gear 14 to rotate on one side of the vertical plate 12. Through the meshing action between the worm gear 14 and the worm wheel 11, the worm wheel 11 drives the rotating shaft 23 to rotate, simultaneously driving the stirring plate 24 to rotate. The rotation of the inner wall of the reactor body 1 heats and stirs the raw materials and catalyst, thereby accelerating the esterification reaction to produce acetate. As the esterification reaction proceeds, gas is generated. The gas is then moved by the exhaust telescopic electric cylinder 15 on one side of the mounting plate 16, which drives the connecting plate 17 to move. The two limiting blocks 26 move between the inner walls of the two limiting grooves 25, thereby moving the sealing sleeve 19 outside the exhaust port 18. This controls the exhaust volume of the exhaust groove 20 and prevents excessive heat loss from the inside of the reactor body 1. Then, the acetate is allowed to settle and separate into layers. Since the density of acetate is less than that of water, acetate is located on the upper layer of water. Finally, the discharge port 21 is controlled by the solenoid valve 22 to accurately discharge water and acetate in sequence, thus completing the use of the energy-saving reactor.
