Description

Technical Field

[0001] This utility model relates to the field of esterification reaction technology, specifically to an esterification reaction vessel and an esterification acceleration device. Background Technology

[0002] An esterification reactor, also known as an esterification vessel, is a device specifically designed for esterification reactions. Esterification typically refers to the reaction of alcohols and carboxylic acids to produce esters and water under the catalysis of acid or alkali. An esterification reactor usually consists of a vessel body, heater, stirrer, heat exchanger, temperature controller, pressure gauge, exhaust device, and safety devices (such as safety valves and rupture discs).

[0003] For example, the patent application number published on the China Patent Network is 202021029238.4, and the patent name is: Esterification Reactor. It includes a first reactor body and a second reactor body. A feed pipe is installed on one side of the top of the first reactor body, and an exhaust pipe is installed on the other side. A support rod is installed on the outer wall of the second reactor body, and a switch is installed on the outer wall of the support rod. A discharge pipe is installed at the bottom of the second reactor body. A handle is installed on the outer wall of the first reactor body. A second conduit is installed on the outer wall of the first reactor body, and a third conduit is installed on the inner wall of the second conduit. A nozzle is installed at one end of the third conduit. This utility model solves the problem of residual generated products on the inner wall of the esterification reactor by setting a second conduit on the first reactor body, which affects the esterification reaction. By setting a baffle on the first reactor body, it solves the problem of the complicated disassembly operation of regularly cleaning the esterification reactor.

[0004] However, existing reactors mainly accelerate the esterification reaction rate through surface stirring structures. Since the stirrer is usually located at a fixed height in the reactor, the stirring force is mainly concentrated in that area, while the materials in other areas may not be sufficiently stirred. Uneven stirring will reduce the contact area between reactants, thereby reducing the reaction rate. It will also lead to local over- or under-reaction, affecting the quality and purity of the product.

[0005] Therefore, it is necessary to design and modify the esterification reactor and esterification acceleration device. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an esterification reactor and esterification acceleration device, which has the advantage of improving the esterification reaction rate. It solves the problem that existing reactors mainly accelerate the esterification reaction rate through surface stirring structures. Since the stirrer is usually located at a fixed height in the reactor, the stirring force is mainly concentrated in that area, while materials in other areas may not be sufficiently stirred. Uneven stirring will reduce the contact area between reactants, thereby reducing the reaction rate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 4 As shown, the present invention provides an esterification reactor and an esterification acceleration device, which includes a base 1;

[0029] The reactor body 2 is placed on top of the base 1;

[0030] A support plate 3 is provided on the top of the base 1, and the reactor body 2 is placed on the surface of the support plate 3.

The side of the swing rod 4 away from the base 1 extends to the outside of the support plate 3 and is sleeved on the surface of the slide rod 5. The slide rod 5 and the swing rod 4 are slidably connected. During the swinging process, the slide rod 5 can be used to push the support plate 3 to rise and fall vertically and vibrate the reactor body 2 placed on its surface. A transmission structure 6 is provided on the back of the base 1. The transmission structure 6 can drive the swing rod 4 to swing automatically.

[0031] refer to Figure 3 The transmission structure 6 includes a connecting frame 7 fixedly connected to the back of the base 1. A reciprocating screw 8 is movably connected inside the connecting frame 7 via a bearing.

A pull rod 11 located inside the swing arm 4 is fixedly connected to both sides of the threaded sleeve 10. The pull rod 11 is slidably connected to the swing arm 4.

[0032] As a technical optimization of this utility model, the threaded sleeve 10 is slidably connected to the pull rod 11 inside the swing rod 4, so that the movement of the threaded sleeve 10 can drive the pull rod 11 and the swing rod 4 to swing. By utilizing the principle of threaded connection, the rotational power of the motor is converted into the swinging power of the swing rod 4, realizing the effective transfer of energy. The setting of the transmission motor 9 provides a stable power source for the entire transmission structure 6, ensuring the continuous and stable swinging of the swing rod 4.

[0033] refer to Figure 2 Limiting rods 12 are fixedly connected to both sides inside the connecting frame 7, and threaded sleeves 10 are sleeved on the surface of the limiting rods 12, with the limiting rods 12 and threaded sleeves 10 slidably connected.

[0034] As a technical optimization of this utility model, the setting of the limiting rod 12 plays a role in limiting and guiding the movement of the screw sleeve 10, preventing the screw sleeve 10 from deviating or being damaged during the movement. The sliding connection between the limiting rod 12 and the screw sleeve 10 ensures the stability and reliability of the screw sleeve 10 during the reciprocating movement.

[0035] refer to Figure 3 The base 1 has guide rods 13 fixedly connected to both sides of the top of the reactor body 2. The bearing plate 3 is sleeved on the surface of the guide rods 13 and slidably connected to the guide rods 13.

[0036] As a technical optimization of this utility model, the guide rod 13 plays a limiting and guiding role in the lifting and lowering of the bearing plate 3, ensuring the stability and accuracy of the bearing plate 3 during the lifting and lowering process. The sliding connection between the bearing plate 3 and the guide rod 13 enables the bearing plate 3 to perform stable lifting and lowering movements under the guidance of the guide rod 13.

[0037] refer to Figure 3 Both sides of the top of the support plate 3 are fixedly connected to the column 14 sleeved on the surface of the guide rod 13. The top of the column 14 is movably connected to the claw 15 sleeved on the surface of the guide rod 13 through the bearing. The side of the claw 15 away from the guide rod 13 extends to the outside of the reactor body 2. The claw 15 can swing around the guide rod 13 as the axis and lock onto the surface of the reactor body 2.

[0038] As a technical optimization of this utility model, the design of the column 14 and the claw 15 provides additional support and fixation for the reactor body 2, enhancing the stability of the reactor body 2. The claw 15 can swing around the guide rod 13 as the axis and lock onto the surface of the reactor body 2, ensuring the connection stability of the reactor body 2.

[0039] refer to Figure 3An extension plate 16 is fixedly connected to both the left and right sides of the base 1. An inclined plate 17 is fixedly connected to the side of the extension plate 16 away from the base 1. The bottom of the inclined plate 17 is set to be inclined outward. The inner side of the inclined plate 17 can contact the outer side of the claw 15. The claw 15 can gradually swing inward when passing the inclined part at the bottom of the inclined plate 17.

[0040] As a technical optimization of this utility model, the design of the extension plate 16 and the inclined plate 17 provides guidance and limiting function for the swing of the claw 15. When the claw 15 passes the inclined part at the bottom of the inclined plate 17, the inner side of the inclined plate 17 can push the claw 15 to swing inward and clamp and fix the reactor body 2.

[0041] The working principle and usage process of this utility model: The reactor body 2 is placed on the support plate 3 on top of the base 1. When the drive motor 9 is started, it drives the reciprocating screw 8 to rotate inside the connecting frame 7. The rotation of the reciprocating screw 8 drives the screw sleeve 10 to reciprocate along its surface. The movement of the screw sleeve 10 pulls the pull rod 11 fixedly connected to it. The pull rod 11 slides inside the swing rod 4. The movement of the pull rod 11 pushes the swing rod 4 to swing around the pin shaft. The swing of the swing rod 4 will use the slide rod 5 to push the support plate 3 to move vertically up and down. The movement of the support plate 3 will cause the reactor body 2 placed on its surface to vibrate. During the movement of the support plate 3, the support plate... The columns 14 and claws 15 on both sides of the base 1 further ensure the stability of the reactor body 2 during the vibration process. When the support plate 3 rises to a certain height, the claws 15 will pass through the extension plates 16 and inclined plates 17 on both sides of the base 1. The bottom of the inclined plate 17 is set to be inclined outward. When the claws 15 pass by, they will be gradually swung inward by the action of the inclined plate 17, so that the claws 15 can be completely locked onto the surface of the reactor body 2, preventing the reactor body 2 from shifting. When the support plate 3 descends, the claws 15 will disengage from the inclined plate 17 under the action of gravity. Then the user can disassemble and replace the reactor body 2 after processing.

[0042] In summary, the esterification reactor esterification acceleration device, through the sliding connection design of the swing rod 4 and the slide rod 5, enables the swing rod 4 to push the support plate 3 to move vertically up and down during the swinging process, thereby generating a vibration effect on the reactor body 2. This vibration helps to accelerate the mixing of materials in the esterification reaction and improve the reaction efficiency.
