Description

Technical Field

[0001] This utility model relates to the technical field of chemical experimental and material synthesis equipment, specifically to a temperature-controlled reaction vessel. Background Technology

[0002] A reaction vessel, also known as a reaction tank or pressure vessel, is a closed container capable of heating, evaporation, cooling, and mixing through structural design and parameter configuration, and capable of completing multiphase reactions such as gas-liquid, liquid-liquid, and gas-liquid-solid reactions. It is mainly used in processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation (e.g., reactors, decomposers, polymerization kettles). This equipment is widely used in petroleum, chemical, rubber, pesticide, pharmaceutical, food, coating, and biomedical industries.

[0003] Traditional reactor designs are simple, often employing only a single-layer cavity or improperly planned media flow paths. This results in poor flow of the heat transfer medium within the jacket, low contact heat exchange efficiency between the heat exchange cavity and the reactor shell, and difficulty in achieving rapid and uniform temperature control response. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a temperature-controlled reactor that can achieve temperature control.

[0005] To solve the above-mentioned technical problems, the present invention provides a temperature-controlled reactor, comprising: a jacket; a reactor shell disposed within the jacket; a reactor cover connected to an opening at the upper end of the reactor shell via a quick-opening sealing mechanism; and a stirring mechanism disposed on the reactor cover, the working end of which extends into the reactor shell. The jacket comprises: a jacket housing, which is a hollow structure, the reactor shell disposed within the jacket housing, forming a heat exchange cavity between the outer wall of the reactor shell and the inner wall of the jacket housing; and a heat transfer medium inlet located at... The lower part of the jacket shell has a heat transfer medium inlet connected to the heat exchange cavity; a heat transfer medium outlet is located at the upper part of the jacket shell and is connected to the heat exchange cavity; a circulator connects the heat transfer medium inlet and the heat transfer medium outlet and is located outside the jacket shell; a control pipe extends from the lower part of the jacket shell into the jacket shell and is connected to the reactor shell; a control component is located inside the control pipe; and a discharge pipe extends from the lower part of the jacket shell into the jacket shell and is connected to the control pipe.

[0006] A heat-conducting medium discharge port is also provided at the lower part of the jacket housing, and the heat-conducting medium discharge port is connected to the heat exchange cavity.

[0007] The quick-opening sealing mechanism includes two clamps, which are arranged around the upper cover of the reactor and the upper end of the reactor shell. One end of the two clamps is rotatably connected by a rotating shaft, and the other end of the two clamps is connected by a safety lock.

[0008] A sealing gasket is provided between the upper cover of the reactor and the upper end of the reactor shell.

[0009] The stirring mechanism includes a motor, a coupling, and a stirring shaft connected in sequence, with the working end of the stirring shaft extending into the reactor shell; a stirring unit is provided on the stirring shaft.

[0010] The stirring unit is a double-layered three-bladed propeller.

[0011] A temperature sensor is provided at the bottom of the stirring shaft.

[0012] The control component is a push rod.

[0013] A proportional unloading valve is provided on the top cover of the reactor.

[0014] An explosion-proof thermal resistor is installed on the top cover of the reactor.

[0015] Compared with existing similar products, the temperature-controlled reactor of this invention has the following advantages: 1. A double-layer quartz jacket structure is adopted (the reaction chamber of the inner reactor shell and the heat exchange chamber of the outer jacket are independently set). Combined with the heat transfer medium inlet at the bottom of the jacket shell, the medium outlet at the top, and an external circulator, a smooth heat transfer medium circulation path is constructed. This solves the problems of low heat exchange efficiency, slow and uneven temperature control response caused by the single cavity structure and improper medium flow path planning of traditional reactors. The heat transfer medium achieves continuous and stable circulation through the circulator, ensuring full contact and heat exchange with the outer wall of the reactor shell. Combined with the excellent thermal conductivity of quartz, rapid adjustment over a wide temperature range from -50℃ to 250℃ can be achieved, resulting in higher temperature control accuracy and better uniformity, meeting the stringent temperature requirements of different processes.

[0016] 2. The reactor adopts a double-layer coaxial structure made of high-strength transparent quartz. After wall thickening and annealing, it retains the advantage of full transparency of quartz material, realizing 360° visualization of the reaction system without dead angles, which is convenient for scientific research process monitoring and teaching demonstration. It also breaks through the technical bottlenecks of traditional single-layer quartz reactors that cannot withstand pressure and high borosilicate transparent reactors that cannot withstand positive pressure. It can work stably in the range of -0.1MPa vacuum to 0.5MPa positive pressure, successfully meeting the dual requirements of "transparent observation" and "resistance to positive and negative pressure", and is suitable for reaction processes that need to be carried out in special pressure environments.

[0017] 3. The reactor lid and reactor shell adopt a double clamp-type quick-opening sealing mechanism. The clamps are rotated and opened and closed by a rotating shaft. Combined with a safety lock and a high-temperature resistant sealing gasket, the opening and closing operation is faster and more convenient than the traditional bolt fixing method, which greatly improves the efficiency of frequent sampling, cleaning and equipment maintenance. At the same time, the dual protection design of "clamp clamping + safety lock locking" combined with the airtightness of the sealing gasket effectively prevents sudden opening caused by misoperation, avoids leakage of reaction medium, and significantly improves the safety of the equipment under positive and negative pressure conditions.

[0018] 4. Equipped with a mechanical stirring system consisting of a motor, coupling, stirring shaft, and double-layer three-blade propeller. The structural design of the double-layer three-blade propeller can enhance the stirring uniformity of the reaction system and improve the material mixing efficiency. At the same time, it adopts a dual sealing method combining mechanical seal / magnetic seal and O-ring, which solves the problem of easy leakage of traditional single-layer seals under alternating positive and negative pressure operation, ensuring that the equipment is leak-free under all working conditions and guaranteeing the stability and safety of the reaction process.

[0019] 5. The reactor lid has multiple pre-installed multi-functional interfaces, which can flexibly install components such as thermometers, pressure gauges, sampling valves, and inlet / outlet pipelines. It can also quickly connect with vacuum systems or gas protection systems to meet the detection, feeding, sampling, and atmosphere control needs of different experimental scenarios. Combined with the equipment's characteristics of being resistant to positive and negative pressure, wide temperature control, and transparent visualization, it can be widely used in multiple fields such as polymer synthesis, catalytic reactions, nanomaterial preparation, fine chemicals, and drug development, and is suitable for different usage scenarios such as scientific research experiments and small-batch production verification.

[0020] 6. The equipment integrates multiple safety components such as explosion-proof RTDs, proportional unloading valves, and heat transfer medium discharge ports. The explosion-proof RTDs can monitor the temperature in real time and prevent overheating risks, the proportional unloading valves achieve safe pressure regulation, and the heat transfer medium discharge ports facilitate the discharge of media during equipment maintenance. Combined with double sealing and safety lock designs, a comprehensive safety protection system is formed, effectively reducing the safety risks caused by temperature runaway, abnormal pressure, and media leakage during the reaction process, and improving the reliability of equipment operation.

[0027] like Figures 1-6As shown, the temperature-controlled reactor of this utility model includes a jacket, a reactor shell 2, a reactor cover 3, and a stirring mechanism. The reactor shell 2 is set inside the jacket. The reactor cover 3 is connected to the opening at the upper end of the reactor shell 2 through a quick-opening sealing mechanism. The stirring mechanism is set on the reactor cover 3, and its working end extends into the reactor shell 2. The overall structure is compact and can specifically solve the defects of traditional reactors such as low heat exchange efficiency, slow and uneven temperature control response, poor transparency, poor pressure resistance, cumbersome operation, and unreliable sealing.

[0028] The jacket includes a jacket shell 5, a heat transfer medium inlet 6, a heat transfer medium outlet 7, a circulator (not shown in the figure), a control pipe 8, control components (not shown in the figure), and a discharge pipe 9. The jacket shell 5 is a hollow structure, and the reactor shell 2 is set inside the jacket shell 5, so that the outer wall of the reactor shell 2 and the inner wall of the jacket shell 5 form an independent heat exchange chamber 1. The reactor shell 2 is made of high-strength transparent quartz and together with the jacket shell 5, it forms a double-layer coaxial structure. It has been reinforced with wall thickness and annealed, which not only retains the full transparency of quartz material, but also enables 360° visualization of the reaction system without dead angles, which is convenient for scientific research process monitoring and teaching demonstration. It also breaks through the technical bottlenecks of traditional single-layer quartz reactors that cannot withstand pressure and high borosilicate transparent reactors that cannot withstand positive pressure. It can work stably in the range of -0.1MPa vacuum to 0.5MPa positive pressure, successfully meeting the dual requirements of "transparent observation" and "resistance to positive and negative pressure", and is suitable for reaction processes under special pressure environments. A heat transfer medium inlet 6 is located at the lower part of the jacket shell 5, and a heat transfer medium outlet 7 is located at the upper part of the jacket shell 5. Both are connected to the heat exchange cavity 1. A circulator connects the heat transfer medium inlet 6 and the heat transfer medium outlet 7 and is located outside the jacket shell 5. This structure creates a smooth circulation path for the heat transfer medium, allowing it to circulate continuously and stably through the circulator, ensuring full contact and heat exchange with the outer wall of the reactor shell 2. Combined with the excellent thermal conductivity of quartz material, rapid adjustment over a wide temperature range from -50℃ to 250℃ is possible, resulting in higher temperature control accuracy and better uniformity. This effectively solves the problem of low heat exchange efficiency caused by the simple cavity structure and improper medium flow path planning of traditional reactors, meeting the stringent temperature requirements of different processes. A heat transfer medium discharge port 10 is also provided at the lower part of the jacket shell 5, which is connected to the heat exchange cavity 1, facilitating medium discharge during equipment maintenance and improving equipment maintenance convenience. One end of the control pipe 8 extends into the jacket housing 5 from the lower part and is connected to the reactor housing 2. The control component is installed inside the control pipe 8. The control component is a push rod. One end of the discharge pipe 9 extends into the jacket housing 5 from the lower part and is connected to the control pipe 8. The operation of the control component can realize the precise discharge of the reaction material and ensure the controllability of the operation.

[0029] The quick-opening sealing mechanism includes two clamps 11, which are arranged around the upper end of the reactor cover 3 and the reactor shell 2. One end of the clamps 11 is rotatably connected via a rotating shaft 12, and the other end is connected via a safety lock 13. A sealing gasket 4 is also provided between the upper end of the reactor cover 3 and the upper end of the reactor shell 2. The sealing gasket 4 is made of high-temperature resistant material, which not only ensures the airtightness of the equipment but also adapts to the use requirements of a wide temperature range. Compared with the traditional bolt fixing method, this double-clamp quick-opening sealing mechanism realizes the rotation and opening of the clamps 11 through the rotating shaft 12 and locks them with the safety lock 13. The opening and closing operation is faster and more convenient, which greatly improves the efficiency of frequent sampling, cleaning and equipment maintenance. At the same time, the dual protection design of "clamp clamping + safety lock locking" can effectively prevent sudden opening caused by misoperation, avoid leakage of reaction medium, and significantly improve the safety of the equipment under positive and negative pressure conditions.

[0030] The stirring mechanism includes a motor 14, a coupling 15, and a stirring shaft 16 connected in sequence. The working end of the stirring shaft 16 extends into the reactor shell 2. A stirring unit, a double-layered three-bladed propeller 17, is mounted on the stirring shaft 16. This structural design enhances the uniformity of the reaction system and improves material mixing efficiency. The stirring mechanism employs a dual sealing method combining mechanical / magnetic seals and O-rings, solving the problem of leakage caused by single-layer seals in traditional stirring devices under alternating positive and negative pressure operations. This ensures leak-free operation under all working conditions, guaranteeing the stability and safety of the reaction process. A thermometer is also installed at the bottom of the stirring shaft 16 to monitor the material temperature inside the reactor shell 2 in real time, providing precise data support for temperature control.

[0031] The reactor lid 3 is equipped with a proportional unloading valve 18 and an explosion-proof RTD 19. The proportional unloading valve 18 enables safe pressure regulation, preventing safety risks caused by abnormal pressure increases inside the reactor. The explosion-proof RTD 19 monitors the equipment's operating temperature in real time, preventing overheating risks. Together with the double seal, safety latch 13, and heat-conducting medium discharge port 10, these components form a comprehensive safety protection system, effectively reducing safety risks caused by temperature runaway, abnormal pressure, and medium leakage during the reaction process, and improving the reliability of equipment operation. Simultaneously, the reactor lid 3 has multiple pre-installed multi-functional interfaces, allowing for flexible installation of components such as thermometers, pressure gauges, sampling valves, and inlet / outlet pipelines. It can also quickly connect to vacuum systems or gas protection systems, meeting the detection, feeding, sampling, and atmosphere control needs of different experimental scenarios.

[0032] This novel temperature-controlled reactor, with its characteristics of resistance to positive and negative pressure, wide temperature control, transparent visualization, convenient operation, reliable sealing, and excellent safety performance, can be widely used in multiple fields such as polymer synthesis, catalytic reactions, nanomaterial preparation, fine chemicals, and drug development. It is suitable for different application scenarios such as scientific research experiments and small-batch production verification, effectively solving many pain points of existing reactors in high-end experimental research and production verification, and has significant practical value and promotion prospects.
