When heating is required, the water in the heated storage tank is heated to raise the temperature to the required level for the first stage. This completes the first... After the initial temperature operation, if cooling is required to proceed to the next reaction stage, the PLC controller will activate the cold water delivery pump to introduce cold water into the system, cooling the water in the jacket to the required temperature for the second stage and maintaining that temperature.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a reaction device for preparing plant polysaccharide hemostatic microspheres, including a jacketed reaction vessel body 1, a heated water storage tank 2, and a top cover 13. Fixing plates 3 are welded to the outer walls of both sides of the surface of the jacketed reaction vessel body 1. Opening components 4 are fixedly connected to the tops of the two fixing plates 3. A first temperature sensor 5 is fixedly installed on one side of the jacketed reaction vessel body 1. A second temperature sensor 6 is fixedly connected to the outer wall of the top surface of the top cover 13. A temperature control component 7 is fixedly connected to the top surface of the heated water storage tank 2. A second intelligent control valve 9 is fixedly connected to the top of the other side of the surface of the jacketed reaction vessel body 1. One end of the second intelligent control valve 9 is connected to a cold water delivery pump 11 through a second delivery pipe 10. An installation pipe is fixedly connected to the surface of the top cover 13, and an ultrasonic component 12 is fixedly connected to the top of the installation pipe. The cover opening assembly 4 includes electric push rods 401 that are fixedly connected to the top of two fixed plates 3. One side of each of the two electric push rods 401 is electrically connected to a PLC controller 402 via a power cord. With the cover opening assembly 4, the purpose of electrically opening the top cover 13 can be achieved. In use, the temperature displayed by the second temperature sensor 6 is checked, and the PLC controller 402 controls the two electric push rods 401 to start simultaneously. The inner rods of the two electric push rods 401 rise and push the connecting ear plate 16, thereby opening the top cover 13. This avoids the need for manual opening, which relies solely on manual temperature judgment and is prone to misjudgment, leading to burns to the operator. It helps to avoid the risk of personal injury in high-temperature environments and improves the safety of operation. Temperature control component 7 includes a heat source delivery pump 701 fixedly connected to the top surface of the heated water storage tank 2. The output end of the heat source delivery pump 701 is connected to a first delivery pipe 702. One end of the first delivery pipe 702 is connected to a first intelligent control valve 703 through a flange. A third temperature controller 704 is fixedly installed on the inlet surface of the first intelligent control valve 703. The ultrasonic component 12 includes a connecting flange 1201 fixedly connected to the top of the mounting pipe. An ultrasonic rod 1202 is fixedly installed inside the connecting flange 1201. A transducer 1203 is fixedly connected to the top of the ultrasonic rod 1202. An ultrasonic generator 1204 is electrically connected to the top of the transducer 1203 via a power cord. Through the coordinated arrangement of the first temperature sensor 5, the second temperature sensor 6, the temperature control component 7, the cold water delivery pump 11, and the ultrasonic component 12, segmented temperature control and improved preparation efficiency can be achieved. During use, the first temperature sensor 5 and the second temperature sensor 6 monitor the temperature at different stages in real time. The first temperature sensor 5 monitors the temperature inside the jacket of the jacketed reactor body 1, and the second temperature sensor 6 monitors the temperature of the material inside the jacketed reactor body 1. When heating is required, the water in the heating storage tank 2 is heated to the temperature required for the first stage. After the first stage temperature operation is completed, if cooling is required to enter the next reaction stage, the PLC controller 402 will start the cold water delivery pump 11 to introduce cold water into the system to cool the water in the jacket, lowering the temperature to the temperature required for the second stage and maintaining that temperature. The ultrasonic generator 1204 generates a high-frequency signal, which is converted into mechanical vibration by the transducer 1203 and acts directly on the material in the reactor through the ultrasonic rod 1202, accelerating the dissolution and dispersion of the plant polysaccharide raw material, preventing material agglomeration, reducing mixing time, and realizing segmented temperature control in the preparation process of plant polysaccharide hemostatic microspheres. This avoids the difficulty in controlling the temperature and affecting the reaction of plant polysaccharides, and helps to improve the efficiency and quality of plant polysaccharide hemostatic microsphere preparation.

[0019] Telescopic outer cylinders 14 are fixedly connected to the diagonal corners of the surfaces of the two fixed plates 3. Telescopic inner rods 15 are slidably connected inside the telescopic outer cylinders 14. Connecting ear plates 16 are fixedly connected to the top of the two telescopic inner rods 15. The inner side of the connecting ear plates 16 is welded to both sides of the outer wall of the top cover 13. The middle part of the bottom surface of the connecting ear plates 16 is fixedly connected to the top of the electric push rod 401. The setting of the telescopic outer cylinders 14 and the telescopic inner rods 15 plays a supporting role.

[0020] A circulation pipe 8 is fixedly connected to one side of the heated water storage tank 2. One end of the circulation pipe 8 is connected to a third intelligent control valve 17 via a flange. One end of the third intelligent control valve 17 is fixedly connected to the lower side of one side of the surface of the jacketed reactor body 1. Through the arrangement of the circulation pipe 8 and the third intelligent control valve 17, the water in the jacket layer is allowed to flow back to the heated water storage tank 2 after being cooled through the circulation pipe 8 and the third intelligent control valve 17, forming a hot water circulation and continuously providing a stable heat source for the reaction.

[0021] The input end of the cold water pump 11 is connected to a water pipe 18, which is connected to an external cold water source. The water pipe 18 serves to transport cold water.

[0022] A stirring motor is fixedly installed in the middle of the top surface of the top cover 13, and a stirrer is fixedly connected to the bottom of the stirring motor. The stirring motor and stirrer are installed in the middle of the top cover 13 to continuously stir the material during the reaction process. Combined with the vibration of the ultrasonic component 12, the uniformity of material mixing is further improved, avoiding rework caused by incomplete local reaction and shortening the overall reaction cycle.

[0023] The top cover 13 is fixedly connected to an air pipe interface 19, a feed inlet 20, and a feed outlet 21. A pressure gauge is fixedly installed on the edge of the outer wall of the top cover 13. The air pipe interface 19, the feed inlet 20, and the feed outlet 21 enable the protective gas, main material, and auxiliary material to be connected separately without opening the cover, avoiding temperature fluctuations and contamination risks caused by opening the cover, while also reducing the number of feeding steps.

[0024] The top of the jacketed reactor body 1 is provided with a pressure groove 22. The pressure groove 22 is sealed to the outer periphery of the bottom surface of the top cover 13. The pressure groove 22 is designed to fit tightly to the outer periphery of the bottom surface of the top cover 13, ensuring the sealing of the reaction process, avoiding reaction failure due to poor sealing, and reducing the need for repeated preparation.

[0025] Three support legs 23 are evenly fixedly connected to the outer wall of the bottom surface of the jacketed reactor body 1. The bottom end of the support legs 23 is fixedly connected to a fixed base plate. The support legs 23 play a supporting role.

[0026] In this invention, the working steps of the device are as follows: First step: When in use, check the temperature displayed by the second temperature sensor 6, and control the two electric push rods 401 to start simultaneously through the PLC controller 402. The inner rods of the two electric push rods 401 rise, push the connecting ear plate 16, and open the top cover 13. The second step: During operation, set the required operating parameters on the PLC controller 402. First, connect the external power supply to heat the water in the heating storage tank 2. The third temperature controller 704 monitors the temperature of the delivered hot water, and the second temperature sensor 6 monitors the actual temperature of the reactants inside the jacketed reactor body 1 to ensure consistency with process requirements. Simultaneously, the water in the jacket layer flows back to the heating storage tank 2 after cooling through the circulation pipe 8 and the third intelligent control valve 17, forming a hot water circulation to continuously provide a stable heat source for the reaction in the next stage. If the second temperature sensor 6 detects a temperature rise during the preparation of plant polysaccharide hemostatic microspheres, the PLC controller 402 can control the cold water delivery pump 11 to automatically turn on and add cold water into the jacket of the jacketed reactor body 1 through the second delivery pipe 10. After the temperature reaches the required temperature, the cold water delivery pump 11 will turn off. At the same time, in each preparation stage, the ultrasonic generator 1204 generates a high-frequency signal, which is converted into mechanical vibration by the transducer 1203 and acts directly on the material in the reactor through the ultrasonic rod 1202 to accelerate the dissolution and dispersion of the plant polysaccharide raw material.
