Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a structure for a triacetin heating reaction vessel. Background Technology

[0002] Triacetin, as an important chemical raw material, is often used in the food industry as a solvent and fixative for food flavorings to stabilize food aromas; in the pharmaceutical industry, it can be used as a plasticizer and solvent for drug preparations to improve drug performance; and in the tobacco industry, it is an ideal plasticizer for cigarette filters to improve the taste of cigarettes.

[0003] In its production process, the performance of the reactor is crucial. Traditional reactor heating relies on a simple jacket, which results in slow heat transfer and high energy consumption. The agitator design is simple and cannot take into account materials in different positions. The number of temperature sensors is small and the accuracy is low, making it difficult to control in real time and accurately. This leads to inconsistent product quality and makes it difficult to meet the increasingly stringent requirements of various industries.

[0004] Therefore, this invention proposes a structure for a triacetin heating reactor. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a structure for a triacetin heating reactor.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a triacetin heating reactor structure, comprising a reactor assembly, the reactor assembly consisting of a stirring cylinder and a stirring top cover, the stirring top cover being disposed at the top opening of the stirring cylinder, and an anchor-type stirring frame located inside the stirring cylinder being rotatably connected to the bottom of the stirring top cover; further comprising:

[0007] The heating vortex assembly consists of a heating sleeve fixedly connected to the bottom of the stirring cylinder and a rotating seat. The rotating seat is located at the bottom of the heating sleeve, and vortex fan blades are rotatably connected to the rotating seat. The inner side of the heating sleeve is provided with a threaded groove.

[0008] Furthermore, a first drive motor is provided on the top of the stirring cover, and the output end of the first drive motor is connected to the anchor-type stirring frame.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: When the first drive motor is turned on, the motor outputs power, and the output end drives the anchor-type stirring frame to rotate at high speed. The shape of the anchor-type stirring frame fits the inner wall and bottom of the reactor. When rotating, on the one hand, its edge can scrape off the material attached to the inner wall to avoid material accumulation and scaling; on the other hand, it can push the material at the bottom of the reactor to roll upward, so that the material generates axial and radial circulation flow. In this way, the material that was originally layered or unevenly distributed can be fully mixed, so that the contact between the reactants is more sufficient and the reaction rate is accelerated.

[0010] Furthermore, the stirring cylinder is provided with connecting bolts that penetrate the stirring top cover. The connecting bolts are arranged in a ring, and the included angle between two adjacent connecting bolts is equal.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the uniform connection force ensures the sealing of the stirring equipment, preventing material leakage during the reaction process, thus ensuring production safety and avoiding material waste. At the same time, the stable connection structure enhances the overall stability of the equipment, reduces vibration and noise during stirring, extends the service life of the equipment, and provides a reliable guarantee for the production of triacetin.

[0012] Furthermore, the pressure relief assembly consists of a pressure relief valve fixedly connected to the top of the stirring cover and a pressure gauge. The pressure gauge is mounted on the pressure relief valve, and its output end is connected to the stirring cover.

[0013] The beneficial effects of adopting the above-mentioned further solutions are: the pressure relief component design effectively ensures the safety of the reaction process, avoids dangerous accidents such as explosions caused by excessive pressure, and the linkage between the pressure gauge and the pressure relief valve realizes accurate pressure monitoring and rapid response. At the same time, it can also prevent pressure fluctuations from affecting the reaction process, ensure the stable progress of the triacetin reaction, reduce the risk of equipment damage, and protect the safety of production personnel and corporate property.

[0014] Furthermore, an arc-shaped mounting bracket is provided on the outer side of the heating sleeve. There are two arc-shaped mounting brackets in total, and the two arc-shaped mounting brackets and the center of the heating sleeve are symmetrical to each other. A heating mechanism is provided between the heating sleeve and the two arc-shaped mounting brackets.

[0015] The beneficial effects of adopting the above-mentioned further solutions are: the uniform heating method ensures that the materials in the reactor are heated evenly, thereby improving the reaction efficiency and quality stability of triacetin; the stable installation structure ensures that the relative positions of the heating mechanism and the heating sleeve are fixed, reducing the risk of loosening of the connection due to vibration, extending the service life of the equipment, and facilitating installation, disassembly and maintenance, thus providing reliable support for production.

[0016] Furthermore, a second drive motor is provided at the bottom of the rotating base, and a vortex fan blade is provided at the output end of the second drive motor. A bottom cover is provided at the bottom of the rotating base.

[0017] The beneficial effect of adopting the above-mentioned further solution is that after the second drive motor is powered on, it drives the vortex fan blades at the output end to rotate at high speed, generating vortices in the space formed by the rotating base and the bottom cover. This airflow can accelerate the diffusion of fluid.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, by setting up vortex fan blades, during operation, the second drive motor is turned on to drive the vortex fan blades to rotate inside the heating sleeve, causing the material inside the heating sleeve to rotate at high speed. Furthermore, under the action of the vortex fan blades, the material inside the heating sleeve generates vortices, causing the water level inside the stirring drum to rise and the collisions to be intense. When used in conjunction with the anchor-type stirring frame, the stirring effect of the reactor is improved. During the rotation process, the material rotation is accelerated under the action of the threaded groove, thereby further increasing the stirring effect. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a triacetin heating reactor structure, including a reactor assembly 1, which consists of a stirring cylinder 11 and a stirring top cover 12. The stirring top cover 12 is located at the top opening of the stirring cylinder 11, and an anchor-type stirring frame 122 located inside the stirring cylinder 11 is rotatably connected to the bottom of the stirring top cover 12. It also includes:

[0031] The heating vortex assembly 3 consists of a heating sleeve 31 fixedly connected to the bottom of the stirring cylinder 11 and a rotating seat 32. The rotating seat 32 is located at the bottom of the heating sleeve 31, and a vortex fan blade 321 is rotatably connected to the rotating seat 32. A threaded groove 35 is provided on the inner side of the heating sleeve 31. Through the setting of the vortex fan blade 321, during operation, the second drive motor 322 is turned on to drive the vortex fan blade 321 to rotate inside the heating sleeve 31, so that the material inside the heating sleeve 31 is in a high-speed rotation state. Furthermore, under the action of the vortex fan blade 321, the material inside the heating sleeve 31 generates a vortex, causing the water level in the stirring cylinder 11 to rise and the collision to be intense. When used in conjunction with the anchor-type stirring frame 122, the stirring effect of the reactor is improved. During the rotation process, under the action of the threaded groove 35, the rotation of the material is accelerated, thereby further increasing the stirring effect.

[0032] A first drive motor 121 is installed on the top of the stirring top cover 12. The output end of the first drive motor 121 is connected to the anchor-type stirring frame 122. When the first drive motor 121 is turned on, the motor outputs power, and the output end drives the anchor-type stirring frame 122 to rotate at high speed. The shape of the anchor-type stirring frame 122 fits the inner wall and bottom of the reactor. When rotating, on the one hand, its edge can scrape off the material attached to the inner wall to avoid material accumulation and scaling; on the other hand, it can push the material at the bottom of the reactor to roll upward, so that the material generates axial and radial circulation flow. In this way, the material that was originally layered or unevenly distributed can be fully mixed, so that the contact between the reactants is more sufficient and the reaction rate is accelerated.

[0033] The mixing cylinder 11 is provided with connecting bolts 13 that penetrate the mixing top cover 12. The connecting bolts 13 are arranged in a ring, and the included angle between two adjacent connecting bolts 13 is equal. The connecting bolts 13 on the mixing cylinder 11 penetrate the mixing top cover 12 and are arranged in a ring with equal included angles. During operation, the connecting bolts 13 are tightened, and the axial tension of the bolts is used to make the mixing cylinder 11 and the mixing top cover 12 fit tightly together. This ring with equal included angle design can make the connection force evenly distributed at the connection between the mixing top cover 12 and the mixing cylinder 11, avoiding loosening or leakage caused by uneven local force.

[0034] The pressure relief assembly 2 consists of a pressure relief valve 22 fixedly connected to the top of the stirring top cover 12 and a pressure gauge 21. The pressure gauge 21 is mounted on the pressure relief valve 22, and its output end is connected to the stirring top cover 12. The pressure gauge 21 monitors the pressure inside the reactor in real time, converting the pressure data into an electrical signal and transmitting it to the control system. When the pressure inside the reactor exceeds the preset safety value, the pressure gauge 21 sends a signal, triggering the pressure relief valve 22 to open automatically. The pressure relief valve 22 quickly releases the excessive pressure inside the reactor, reducing the pressure to a safe range. The design of the pressure relief assembly 2 effectively ensures the safety of the reaction process, avoiding dangerous accidents such as explosions caused by excessive pressure. The linkage between the pressure gauge 21 and the pressure relief valve 22 achieves accurate pressure monitoring and rapid response, while also preventing pressure fluctuations from affecting the reaction process, ensuring the stable progress of the triacetin reaction, reducing the risk of equipment damage, and protecting the safety of production personnel and company property.

[0035] An arc-shaped mounting bracket 311 is provided on the outer side of the heating sleeve 31. There are two arc-shaped mounting brackets 311, and the two arc-shaped mounting brackets 311 and the center of the heating sleeve 31 are symmetrical. A heating mechanism 34 is provided between the heating sleeve 31 and the two arc-shaped mounting brackets 311. The two symmetrically distributed arc-shaped mounting brackets 311 stably clamp the heating sleeve 31, and the heating mechanism 34 is located between them. When working, the heating mechanism 34 is energized to generate heat, and the heat is evenly transferred to the heating sleeve 31 through heat conduction and heat radiation. The design of the symmetrical arc-shaped mounting brackets 311 ensures that the distance between the heating mechanism 34 and the heating sleeve 31 is consistent, ensuring uniform heat transfer and avoiding local overheating or overcooling. The uniform heating method makes the material in the reactor evenly heated, improving the reaction efficiency and quality stability of triacetin. The stable installation structure ensures that the relative position of the heating mechanism 34 and the heating sleeve 31 is fixed, reducing the risk of loosening of the connection due to vibration, extending the service life of the equipment, and facilitating installation, disassembly and maintenance, providing reliable support for production.

[0036] A second drive motor 322 is provided at the bottom of the rotating base 32. A vortex fan blade 321 is provided at the output end of the second drive motor 322. A bottom cover 33 is provided at the bottom of the rotating base 32. After the second drive motor 322 is powered on, it drives the vortex fan blade 321 at the output end to rotate at high speed, generating a vortex in the space formed by the rotating base 32 and the bottom cover 33. This airflow can accelerate the diffusion of fluid.
