Description

Technical Field

[0001] This utility model relates to the field of esterification reaction technology, and in particular to a continuous synthesis apparatus for efficient esterification reaction. Background Technology

[0002] Continuous synthesis equipment refers to an integrated system capable of continuously operating esterification reactions (reactions of alcohols with carboxylic acids / anhydrides to produce esters and water under the action of a catalyst). Unlike traditional batch reactors (batch feeding, reaction, and discharge), its core feature is a closed-loop process of continuous feeding, continuous reaction, real-time separation, and product output, enabling efficient, stable, and large-scale production of esterification reactions.

[0003] In the existing technology, the raw materials in the esterification reaction are all continuously synthesized in the reactor. The efficiency of the esterification reaction is improved by the coordination of feeding and discharging. When the raw materials enter the reactor, they are directly injected. Then, the mixing and reaction of the raw materials are promoted by the stirring component. In this process, it takes a long time to achieve complete mixing, resulting in low reaction efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology of esterification reactions, where the raw materials are continuously synthesized in a reactor. The efficiency of the esterification reaction is improved by coordinating the feeding and discharging processes. When the raw materials enter the reactor, they are directly injected, and then the mixing and reaction of the raw materials are promoted by the stirring components. This process takes a long time to achieve complete mixing, resulting in low reaction efficiency. Therefore, this invention proposes a high-efficiency continuous synthesis device for esterification reactions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a continuous synthesis device for efficient esterification reaction, comprising a reaction tank body, a tank cover fixedly connected to the upper end of the reaction tank body, a feed inlet fixedly connected to the upper end of the tank cover, an assembly base fixedly connected to the outer surface of the tank cover, a second drive motor fixedly connected to one side of the assembly base, an inner drive shaft fixedly connected to the output end of the second drive motor, an assembly kit provided inside the tank cover, one end of the inner drive shaft fixedly connected to the assembly kit, a material dispersing rod fixedly connected to the outer surface of the assembly kit, the number of feed inlets being at least four and an even number, with each pair of adjacent feed inlets forming a group, the guide vanes and the material dispersing rod located below each group of feed inlets, the rotation range covering the lower end of the feed inlets to ensure sufficient tapping of the raw materials.

[0006] Preferably, the outer surface of the assembly and one side of the bulk rod are fixedly connected with a guide vane.

[0007] Preferably, a discharge valve is installed at the lower end of the reaction vessel.

[0008] Preferably, a motor base is fixedly connected to the upper middle part of the can lid, and a No. 1 drive motor is fixedly connected to the upper end of the motor base.

[0009] Preferably, the output end of the first drive motor is fixedly connected to a stirring shaft.

[0010] Preferably, stirring blades are fixedly connected to the outer surface of the stirring shaft.

[0011] Preferably, a baffle plate is fixedly connected inside the reaction vessel body, and a mounting base is fixedly connected above the middle of the outer surface of the reaction vessel body.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up the material dispersing rod, when the raw material enters, the rotation of the material dispersing rod can knock and disperse the raw material, so that the raw material is dispersed inside the reaction tank by impact, thereby initially mixing the raw material and improving the esterification efficiency. Moreover, this method has a relatively simple structure and is relatively convenient to use.

[0014] 2. In this utility model, the airflow in the reaction vessel body and the interior space of the vessel cover is facilitated by the flow of the guide vanes. This, combined with the airflow, further improves the mixing efficiency between the raw materials. The single-layer guide vanes have a smaller impact on the airflow, thus avoiding the influence of a large-scale airflow on the entry of the raw materials. The turbulence protrusions further improve the mixing efficiency of the raw materials during mixing, thereby ensuring the esterification efficiency. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a continuous synthesis device for efficient esterification reaction, including a reaction tank body 1, a tank cover 2 fixedly connected to the upper end of the reaction tank body 1, a feed inlet 4 fixedly connected to the upper end of the tank cover 2, an assembly seat 8 fixedly connected to the outer surface of the tank cover 2, a second drive motor 7 fixedly connected to one side of the assembly seat 8, an inner drive shaft 12 fixedly connected to the output end of the second drive motor 7, an assembly kit 14 provided inside the tank cover 2, one end of the inner drive shaft 12 fixedly connected to the assembly kit 14, a material dispersing rod 15 fixedly connected to the outer surface of the assembly kit 14, the number of feed inlets 4 is at least four and is an even number, each pair of adjacent feed inlets 4 is a group, the guide vanes 13 and the material dispersing rod 15 are located below each group of feed inlets 4, the rotation range covers the lower end of the feed inlets 4 to ensure sufficient tapping of the raw materials.

[0022] The specific settings and functions of this embodiment will be described in detail below. With the setting of the material dispersing rod 15, when the raw material enters, the rotation of the material dispersing rod 15 can be used to knock and disperse the raw material, so that the raw material is dispersed inside the reaction tank 1 through impact, thereby initially mixing the raw material and improving the esterification efficiency. Moreover, in this way, the structure is relatively simple and the use is relatively convenient.

[0023] Example 2: Figure 1 - Figure 3 As shown, a guide vane 13 is fixedly connected to the outer surface of the assembly 14 and to one side of the material handling rod 15. A discharge valve 16 is installed at the lower end of the reaction tank body 1. A motor base 5 is fixedly connected to the middle of the upper end of the tank cover 2. A first drive motor 6 is fixedly connected to the upper end of the motor base 5. A stirring shaft 9 is fixedly connected to the output end of the first drive motor 6. A stirring vane 10 is fixedly connected to the outer surface of the stirring shaft 9. A turbulence protrusion 11 is fixedly connected to the inside of the reaction tank body 1. A mounting base 3 is fixedly connected to the upper middle part of the outer surface of the reaction tank body 1.

[0024] The overall effect of this embodiment is that, by setting the guide vanes 13, the airflow in the internal space of the reaction vessel body 1 and the vessel cover 2 can be facilitated. In conjunction with the airflow, the mixing efficiency between raw materials is further improved. By setting the single-layer guide vanes 13, the impact on the airflow is small, which can avoid the large-scale airflow affecting the entry of raw materials. By setting the turbulence protrusions 11, the mixing efficiency of raw materials is further improved when mixing them, so as to ensure the esterification efficiency.

[0025] The method of use and working principle of this device: When in use, turn on the second drive motor 7, and then inject the raw material from the feed port 4. When the raw material falls on the dispersing rod 15, it is dispersed and impacts the inner wall of the tank cover 2. Combined with the airflow caused by the guide vane 13, the premixing effect of the raw material is increased and the esterification efficiency is improved. Then the raw material falls into the reaction tank 1. Turn on the first drive motor 6, so that the stirring blade 10 and the turbulence protrusion 11 will mix the raw material a second time, so that the raw materials can fully react and carry out the esterification reaction.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
