The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned figures are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a high pressure reactor which is convenient for sampling, such as Figure 1-4 As shown, the high-pressure reactor for convenient sampling comprises: a reactor body 1, on which a reactor cover 2 is provided, and on which a pressure gauge 3 and a feed pipe 4 are provided; a sampling valve 5, which is arranged on one side of the reactor body 1; a fixing plate 6, which is fixedly installed on one side of the reactor body 1, and on which a sampling bottle 7 is provided; a fixing column 8, which is fixedly installed on the fixing plate 6, and on which a fixing box 9 is provided, on which two clamping rings 10 are slidably installed, and a sampling tube 11 is clamped on the two clamping rings 10; a driving mechanism, which is arranged on the fixing box 9 and is used to drive the two clamping rings 10 to clamp the sampling tube 11.

[0022] In this embodiment, the kettle body 1 serves as the main container for the high-pressure reaction, and the pressure gauge 3 equipped on the kettle cover 2 can monitor the pressure in the kettle in real time to ensure safe operation. The feed pipe 4 is used to add reactants into the kettle. The two together constitute the basic structure of the high-pressure reactor. The setting position of the sampling valve 5 provides an interface for subsequent sampling operations. The sampling process can be optimized in combination with subsequent designs. The fixing plate 6 is firmly installed on one side of the kettle body 1, and a sampling bottle 7 is provided thereon, so that the sampling bottle 7 can be stably placed, which is convenient for receiving samples taken out of the reactor, reducing physical movement and potential safety risks during the sampling process. A series of components including the fixing column 8, the fixing box 9, the clamping ring 10 and the sampling tube 11 constitute a safe clamping and operating mechanism for the sampling tube 11. The fixing column 8 and the fixing box 9 provide a stable installation foundation for the clamping ring 10. The two clamping rings 10 are slidably mounted on the fixed box 9, and can tightly clamp the sampling tube 11. Without directly opening the reactor cover 2 or exposing it to a high-pressure environment, samples can be safely extracted through the sampling tube 11, which greatly reduces the difficulty of operation and safety risks. The driving mechanism arranged on the fixed box 9 is used to drive the two clamping rings 10 to clamp the sampling tube 11, which not only improves the sampling efficiency, but also ensures the stable clamping of the sampling tube 11 during the sampling process, and prevents safety problems such as sample leakage or the sampling tube 11 falling off due to improper operation. Through the optimized sampling design, the operator is avoided from being directly exposed to the potentially dangerous environment of the high-pressure reactor, which significantly reduces the safety risks during the sampling process, and the sampling process is more convenient and efficient, reducing the uncertainty and complexity of manual operation, and improving the overall work efficiency.

[0023] In a further preferred embodiment of the utility model, the driving mechanism includes a bidirectional motor 12, a bidirectional screw 13 and two slides 14, the bidirectional motor 12 is fixedly mounted on one side of the fixed box 9, the bidirectional screw 13 is rotatably mounted on the fixed box 9, the two slides 14 are threadedly mounted with slides 14, the two slides 14 are slidably fitted with the inner wall of the fixed box 9, and the two slides 14 are respectively connected to the two retaining rings 10.

[0024] In this embodiment, the bidirectional motor 12 serves as the core power source of the driving mechanism. The bidirectional motor 12 is fixedly installed on one side of the fixed box 9. It has the function of forward and reverse rotation, and can drive the bidirectional screw 13 to rotate clockwise or counterclockwise as needed, thereby realizing the synchronous or reverse movement of the two slides 14 and the retaining ring 10. When the bidirectional motor 12 drives the screw to rotate, the rotation directions of the threads on both sides are opposite, so that the two slides 14 threadedly matched with it can move in opposite directions or the same direction. Each slide 14 is threadedly installed on the bidirectional screw 13 and slides and fits with the inner wall of the fixed box 9, ensuring that the slide 14 can slide smoothly along the inner wall of the fixed box 9 when the screw rotates without deviation or shaking. At the same time, the slide 14 is connected to the retaining ring 10, so the movement of the slide 14 will drive the retaining ring 10 to move synchronously, thereby clamping or loosening the sampling tube 11.

[0025] In a further preferred embodiment of the utility model, a lifting screw 15 is rotatably mounted on the fixed column 8, a slider 16 is threadedly mounted on the lifting screw 15, an electric telescopic rod 17 is fixedly mounted on the slider 16, and the output rod of the electric telescopic rod 17 is connected to the fixed box 9.

[0026] In this embodiment, the lifting screw 15 is rotatably installed on the fixed column 8. The lifting screw 15 is an important component for adjusting the sampling height. By rotating the lifting screw 15, the slider 16 that cooperates with its thread can be driven to move up and down, thereby realizing the position adjustment of the sampling mechanism in the vertical direction. The slider 16 is threadedly installed on the lifting screw 15 and moves up and down with the rotation of the lifting screw 15. The output rod of the electric telescopic rod 17 is connected to the fixed box 9, which means that the electric telescopic rod 17 can drive the fixed box 9 (and the components such as the clamping ring 10 and the sampling tube 11 connected thereto) to perform telescopic movement in the horizontal direction, so that the sampling mechanism can more flexibly adapt to different sampling needs.

[0027] In a further preferred embodiment of the present invention, a lifting motor 18 is fixedly mounted on an inner wall of one side of the fixing column 8 , and an output shaft of the lifting motor 18 is fixedly connected to one end of the lifting screw 15 .

[0028] In this embodiment, the lifting motor 18 is fixedly installed on the inner wall of one side of the fixed column 8, and is a key component for driving the lifting screw 15 to rotate. By controlling the start, stop and rotation direction of the lifting motor 18, precise control of the lifting screw 15 can be achieved, thereby driving the slider 16 and the electric telescopic rod 17 to move up and down. The output shaft of the lifting motor 18 is fixedly connected to one end of the lifting screw 15. This direct connection method ensures efficient power transmission. When the lifting motor 18 is started, the rotation of its output shaft will be immediately converted into the rotation of the lifting screw 15, thereby driving the entire lifting mechanism to work, greatly improving the convenience and efficiency of operation.

[0029] In a further preferred embodiment of the utility model, a stirring motor 19 is fixedly installed on the top of the kettle cover 2, and a stirring rod 20 is rotatably installed on the kettle cover 2, and one end of the stirring rod 20 is fixedly connected to the output shaft of the stirring motor 19.

[0030] In this embodiment, the stirring motor 19 is fixedly installed on the top of the kettle cover 2 as a power source for driving the stirring rod 20 to rotate. The stirring rod 20 is rotatably installed on the kettle cover 2, and one end of the stirring rod 20 is fixedly connected to the output shaft of the stirring motor 19. Driven by the stirring motor 19, the stirring rod 20 can penetrate into the interior of the reactor to stir the materials in all directions, ensuring that the materials can be fully contacted and mixed during the reaction process, which is beneficial to improving the reaction efficiency and product quality. The rotation of the stirring rod 20 can break the interfacial tension between the materials and promote the mass transfer and heat transfer process between the materials, thereby accelerating the reaction rate and improving the reaction efficiency.

[0031] In a further preferred embodiment of the present invention, both inner walls of the kettle body 1 are provided with mounting grooves 21 , heating plates 22 are fixedly installed in the two mounting grooves 21 , and the kettle cover 2 is provided with a temperature sensor 23 for detection.

[0032] In this embodiment, the mounting groove 21 is located on the inner wall of both sides of the kettle body 1, and is used to fix the heating plate 22. The heating plate 22 is fixedly installed in the mounting groove 21 and is a heating element of the reactor. The heating plate 22 generates heat by electric heating or other heating methods to provide the required reaction temperature for the material in the reactor. By controlling the heating power and time of the heating plate 22, the reaction temperature can be accurately controlled. The temperature sensor 23 is arranged on the kettle cover 2, and is used to monitor the temperature in the reactor in real time. The temperature sensor 23 transmits the detected temperature signal to the control system. The control system adjusts the heating power of the heating plate 22 according to the preset temperature curve or the operator's instructions to keep the temperature in the reactor within the set range.

[0033] In a further preferred embodiment of the utility model, a placement groove 24 is provided on the fixing plate 6, and the placement groove 24 is used to place the sampling bottle 7, and the top of the sampling bottle 7 is fixedly connected to a sample receiving funnel 25 for receiving samples.

[0034] In this embodiment, the placement groove 24 is opened on the fixed plate 6, which is specially used for placing the sampling bottle 7, so that the sampling bottle 7 can maintain a stable position during the sampling process and is not easy to tip over or slide, thereby ensuring the safety and accuracy of the sampling operation. The sample receiving funnel 25 is fixedly connected to the top of the sampling bottle 7 and serves as a channel for the sample to enter the sampling bottle 7. The sample receiving funnel 25 allows the sample to fall into the sampling bottle 7 more accurately, reducing the possibility of the sample splashing or adhering to the sampling device. At the same time, the sample receiving funnel 25 also has a certain buffering effect, which can reduce the impact force when the sample flows into the sampling bottle 7 and protect the sampling bottle 7 from damage.

[0035] To sum up, compared with the relevant technologies, the present device has achieved a significant improvement in the efficiency, safety and operational convenience of the sampling process as a whole. It can complete the sampling process quickly and accurately, reduce the tediousness and time consumption of manual operation, significantly improve the sampling efficiency, and ensure the safety of samples and operators during the sampling process. At the same time, through the temperature monitoring and control functions, safety accidents caused by excessive temperature are prevented. In addition, the loss and contamination of samples during the sampling process are reduced, the quality of samples is guaranteed, the user experience is optimized, the operation complexity is reduced, the work efficiency is improved, and a more convenient and safe sampling solution is provided for operators.
