It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0048] Example 1:

[0049] As shown in Figure 1 , Figure 2 and Figure 4 , the present embodiment provides a temperature control reaction kettle, comprising:

[0050] Support frame 1, which is provided with a reaction kettle body 2;

[0051] Top cover 3, arranged at the top of the reaction kettle body 2;

[0052] Stirring mechanism 9, arranged on the top cover 3 and located inside the reaction kettle body 2, for stirring and mixing the materials in the reaction kettle body 2;

[0053] Heating unit 4, arranged on the outer wall of the reaction kettle body 2, for heating the reaction kettle body 2;

[0054] Cooling unit 5, arranged outside the reaction kettle body 2, for reducing the temperature of the reaction kettle body 2 by means of cooling liquid;

[0055] Temperature sensor 6, installed inside the reaction kettle body 2, for real-time monitoring of the temperature in the reaction space;

[0056] Control system 7, electrically connected with the temperature sensor 6, the heating unit 4 and the cooling unit 5, for controlling the working state of the heating unit 4 and the cooling unit 5 according to the temperature data collected by the temperature sensor 6, so as to adjust the temperature of the internal space of the reaction kettle body 2;

[0057] Shaking mechanism 8, arranged on the support frame 1, for rotating and shaking the internal materials of the reaction kettle body 2 to avoid material accumulation;

[0058] The shaking mechanism 8 comprises:

[0059] Rotating shaft 81, rotatably arranged on the left and right sides of the support frame 1, both of which are connected with the reaction kettle body 2;

[0060] Worm gear 82, arranged on one of the rotating shafts 81;

[0061] Fixed plate 83, arranged on the support frame 1;

[0062] Worm 84, rotatably arranged on the fixed plate 83, which cooperates with the worm gear 82;

[0063] Rotating wheel 85, arranged at the front end of the worm 84.

[0064] In the technical solution, the reactant is added into the reaction kettle, the temperature sensor 6 monitors the real-time temperature, detects the current temperature in the reaction kettle, the temperature sensor 6 can accurately capture the temperature fluctuation of the reaction space, and provides data support for the control system 7, the control system 7 automatically adjusts the working state of the heating unit 4 and the cooling unit 5 according to the real-time temperature data of the sensor, so as to maintain the temperature of the reaction space in the set range, and avoid affecting the reaction efficiency due to too high or too low temperature. If the reaction temperature is lower than the set value, the control system 7 controls the heating unit 4 to start working, and the temperature of the reaction kettle is raised by heating; if the reaction temperature is higher than the set value, the control system 7 controls the cooling unit 5 to start, and the heat in the reaction kettle is absorbed by the cooling liquid, so as to reduce the reaction temperature. In the reaction process, the stirring mechanism 9 starts to stir the materials in the reaction kettle, so as to ensure that the materials can be uniformly mixed, and the reaction efficiency is improved. At the same time, the shaking mechanism 8 starts to work, the user rotates the rotating wheel 85, the rotating wheel 85 drives the worm 84 to rotate, the worm 84 cooperates with the worm wheel 82, so as to drive the worm wheel 82 to rotate, the worm wheel 82 drives the reaction kettle body 2 to rotate and shake through the rotating shaft 81, which effectively avoids the accumulation of materials, especially in the case of high viscosity or slow reaction rate, the materials may be deposited or locally accumulated, the shaking mechanism 8 can effectively avoid this problem, and ensure that the materials are uniformly distributed in the reaction kettle. In order to fully stir the materials by the stirring mechanism 9. The control system 7 adjusts the working state of the heating and cooling unit 5 according to the temperature data fed back by the temperature sensor 6 in real time, so as to ensure that the temperature in the reaction kettle remains in the predetermined range. Through the accurate temperature control system, effective material mixing and shaking mechanism, the uniformity of the reactants, the stability of the temperature and the high efficiency of the reaction in the reaction process are ensured.

[0065] Specifically, the top cover 3 is connected with the reaction kettle body 2 with good sealing performance, which prevents the leakage of materials during the reaction, and can effectively bear the stirring mechanism 9. The stirring mechanism 9 plays a key role in the stirring and mixing of the materials in the reaction kettle. Through stirring, the reactant can be uniformly distributed, the reaction rate can be increased, and the phenomenon of uneven reaction or local overheating can be avoided. The heating unit 4 is arranged on the outer wall of the reaction kettle body 2, and is used for heating the reaction kettle body 2. Generally, the temperature of the reaction kettle needs to be accurately controlled, especially for some chemical reactions which need to be carried out at high temperature. The heating unit 4 can quickly raise the temperature of the reaction kettle to the preset temperature. The heat source of the heating unit 4 can be an electric heater, steam heating, hot oil heating, etc., which is selected according to the actual reaction requirement. The heating process is adjusted by the controlled system to ensure the constant temperature. The cooling unit 5 reduces the temperature of the reaction kettle through the cooling liquid (such as water, cooling oil, etc.). When the reaction needs to be carried out at a lower temperature, the cooling unit 5 quickly absorbs the heat in the reaction kettle, and reduces the temperature through the circulation of the cooling liquid. The cooling liquid is usually circulated through the pipeline system to take away the heat of the reaction kettle body 2, so as to ensure the stability of the temperature control system 7.

[0066] As Figure 1 and Figure 3 shown, in this embodiment, the optimized, stirring mechanism 9 includes:

[0067] a transmission shaft 91 rotatably arranged on the top cover 3;

[0068] a plurality of stirring paddles 92 evenly spaced along the length direction of the transmission shaft 91, and the stirring paddles 92 are located inside the reactor body 2;

[0069] a motor 93 arranged outside the top cover 3, and the output shaft of the motor 93 is connected with the transmission shaft 91.

[0070] In this technical solution, when it is necessary to stir the materials in the reactor, first start the motor 93, the motor 93 drives the transmission shaft 91 to rotate through its output shaft, the transmission shaft 91 drives the plurality of stirring paddles 92 to rotate along the axis direction of the reactor, and then the materials in the reactor are stirred, and the stirring paddles 92 continuously disturb the materials through rotation, so that the materials are fully mixed. The contact between the reactants is enhanced, which promotes the improvement of the reaction rate, and also helps the uniform distribution of heat. At the same time, the user rotates the rotating wheel 85, the rotating wheel 85 drives the worm 84 to rotate, the worm 84 cooperates with the worm gear 82, so that the worm gear 82 drives the rotating shaft 81 to rotate, the rotating shaft 81 drives the reactor body 2 to rotate, and the rotating and shaking action of the reactor body 2 effectively avoids the accumulation of materials, especially in some cases of high viscosity or slow reaction rate, the materials may be deposited or locally accumulated, plus the stirring of the stirring paddles 92, so that the materials in the reactor are more fully stirred. The temperature sensor 6 monitors the temperature inside the reactor in real time, and if the temperature deviates from the set range, the temperature control system can automatically adjust the heating or cooling device to ensure that the reaction is carried out under the best temperature condition. According to the needs of the reaction, the operator can change the rotating speed of the stirring paddles 92 by adjusting the rotating speed of the motor 93, so as to adjust the stirring intensity of the materials in the reactor. In this way, it can avoid the accumulation of materials at the bottom or wall of the reactor, especially when high-viscosity, easily-deposited reactants are used, effective stirring can ensure that the reactants are always in a suspended state.

[0071] As Figure 4 shown, in this embodiment, the optimized, temperature sensor 6 is one of a thermocouple, an RTD sensor or an infrared temperature sensor 6.

[0072] In the present technical solution, thermocouples are commonly used for higher temperature range measurements, which generate a voltage change through the contact point of two different metals, the higher the temperature, the greater the voltage change. Its advantages are fast response speed, low price, and is suitable for high temperature environment. RTD sensors determine temperature by measuring resistance changes caused by temperature, with high precision and stability, and are commonly used in low temperature measurement scenarios. Infrared temperature sensor 6 determines temperature by measuring infrared radiation emitted by objects, non-contact measurement, suitable for high temperature environment where it is difficult to contact or need to avoid contact. The main purpose of these temperature sensors 6 is to monitor the temperature change of the reaction material in the reaction kettle in real time, so as to provide feedback for the control of the reaction process. Temperature is a key control variable in chemical reactions, and through accurate temperature monitoring, the reaction can be ensured to proceed under optimal conditions, avoiding incomplete reaction or equipment damage caused by overheating or overcooling.

[0073] As shown in Figure 4 In the present embodiment, the optimized control system 7 also includes a temperature warning function 71 that sends an alarm signal when the temperature exceeds the set range.

[0074] In the present technical solution, both too high or too low temperature in the reaction kettle can lead to incomplete reaction, reaction material quality change, and even may cause danger. Therefore, the control system 7 can monitor in real time and timely alarm when abnormal according to the preset temperature range, so as to prevent accidents. By introducing the temperature warning function 71, immediate response to abnormal temperature changes can be achieved, and some preset control measures such as adjusting heating, cooling equipment or stopping can be automatically executed, reducing manual intervention and improving automation level.

[0075] As shown in Figure 2 and Figure 3 In the present embodiment, the optimized reaction kettle body 2 is provided with a heat preservation shell 10 on the outer surface, which is used to reduce heat loss and improve temperature control efficiency.

[0076] In the present technical solution, during the heating or cooling process of the reaction kettle body 2, if there is no effective heat preservation measure, the external heat will be lost through the outer surface of the reaction kettle. This not only wastes energy, but also may affect the stability and efficiency of the reaction. The setting of the heat preservation shell 10 can effectively isolate the heat exchange between the external environment and the reaction kettle, reduce the loss of heat, and maintain the stability of the internal reaction temperature. By reducing the loss of heat, the temperature control system can more accurately adjust the temperature inside the reaction kettle. This makes it unnecessary to overheat or cool during the chemical reaction process, saving energy and improving the response speed and accuracy of temperature control, thereby improving the efficiency of the overall reaction process. The main function of the heat preservation shell 10 is to isolate the temperature of the external environment from the temperature inside the reaction kettle and reduce the loss of heat. Usually, materials with excellent heat insulation performance (such as rock wool, glass wool or foam materials) are used to manufacture the heat preservation shell 10, so that even if the temperature inside the reaction kettle is high, the external environment will not be affected by too much heat. By reducing heat loss, the temperature control system of the reaction kettle can work more efficiently, reducing the energy consumption of heating or refrigeration, thereby achieving energy saving effect. This is particularly important for long-term operation in industrial reaction processes, which can significantly reduce energy consumption.

[0077] Embodiment 2:

[0079] As shown in Figure 1 and Figure 3 In the present embodiment, an optimized locking mechanism 11 is provided between the top cover 3 and the reaction kettle body 2, which includes:

[0080] The grooves 111 are provided on the outside of the top cover 3 and the reaction kettle, and the grooves 111 are uniformly distributed in the circumferential direction.

[0081] The locking rod 112 is rotatably arranged outside the reaction kettle body 2, and the locking rod 112 is locked in the groove 111.

[0082] In the technical solution, the connection between the top cover 3 and the reaction kettle body 2 must be very stable during the high-temperature and high-pressure chemical reaction process to prevent the leakage of gas or liquid in the reaction kettle, thereby ensuring the safety of the reaction process. The locking mechanism 11 functions to lock the top cover 3 to ensure that it will not loosen or fall off due to changes in reaction conditions (such as temperature and pressure fluctuations). Through the close cooperation of the locking rod 112 and the groove 111, the top cover 3 is not easily loosened or accidentally opened during operation, further improving the safety of the equipment. When it is necessary to open the top cover 3, the operator can complete the locking or unlocking operation by simply rotating the locking rod 112, which is more efficient and easier to operate than the traditional threaded locking method. In this way, a stable and firm connection is ensured between the top cover 3 of the reaction kettle and the reaction kettle body 2, avoiding loosening or falling off due to changes in internal and external pressure or equipment vibration and other external factors during the reaction process.

[0087] a hopper 122 arranged on the feeding pipe 121;

[0088] a ball valve 123 arranged on the feeding pipe 121 for controlling the addition of materials.

[0089] In the technical solution, first, the material is loaded into the hopper 122 through an external conveying system, the material is guided into the feeding pipe 121 by gravity, and the material is conveyed to the inside of the reaction kettle through the pipe, and the ball valve 123 controls the flow of the material in the feeding pipe 121. When it is necessary to add material, the operator adjusts the switch of the ball valve 123 to accurately control the amount of material added, effectively preventing the material flow from being too large or too small, thereby ensuring the controllability of the reaction process. During the material addition process, the temperature control system of the reaction kettle continuously monitors and adjusts the temperature inside the reaction kettle. The temperature control system usually includes heating or cooling devices to ensure that the reaction temperature is within the set range, thereby ensuring the efficiency and stability of the reaction. After the material is completely added, the ball valve 123 can be closed.
