[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] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a pressure reactor, including a reactor body 1. A top cover 2 is bolted to the top of the reactor body 1. The reactor body 1, as the core load-bearing component of the pressure reactor, provides a closed space for material reaction. Its top is bolted to the top cover 2, allowing for quick assembly and disassembly, facilitating equipment maintenance and material cleaning. Multiple monitoring instruments 3 are installed on the top of the top cover 2. These instruments can monitor key parameters such as pressure and temperature in real time during the reaction process, ensuring reaction stability and product quality, and providing operators with accurate reaction status information. An installation port 4 is provided on the top of the top cover 2, through which a stirring device is installed to promote thorough mixing of materials and accelerate the reaction speed. An exhaust vent is located on the left side of the top of the top cover 2. Outlet 5 is an important channel for regulating the internal pressure of the reactor. During the reaction, when the pressure inside the reactor increases due to gas production or other reasons, the excess gas can be discharged by opening outlet 5 to maintain the pressure inside the reactor within a safe range. An observation window 6 is provided on the top right side of the top cover 2. Operators can directly observe the reaction status of the materials inside the reactor through the observation window 6, including the color change of the materials and the intensity of the reaction, without opening the reactor. This allows for timely monitoring of the reaction process, avoids interference from external factors, and ensures the safety of the operators. A feed inlet 7 is provided on the front side of the reactor body 1, which is responsible for the input of materials. An outlet 8 is provided at the bottom of the reactor body 1, which is used to discharge the materials after the reaction is completed.
[0031] Reference Figure 2 and Figure 3A sampling assembly includes a sampling tube 9 and a pressure reactor, wherein the pressure reactor is the aforementioned pressure reactor. The outer wall of the sampling tube 9 is fixedly connected to the bottom inner wall of the reactor body 1. A sampling valve 18 is installed on the outside of the sampling tube 9. The sampling tube 9 is located at the bottom of the reactor body 1, and its structure design, which extends deep into the bottom of the reactor, enables the acquisition of representative deep material samples. The externally installed sampling valve 18 can control the outflow of the sample. During the sampling process, the sample collection volume is precisely controlled by opening and closing the sampling valve 18. An installation assembly is fixedly connected to the bottom end of the sampling tube 9. The installation assembly includes a fixing plate 10. The top end of the fixing plate 10 is fixedly connected to the bottom end of the sampling tube 9, and the bottom end of the fixing plate 10 is fixedly connected to an installation plate 11 by bolts. The installation plate 11 and A sealing ring is provided between the fixing plates 10. The mounting plate 11 is used to fix the sampling tube 9 to the reactor, ensuring the installation stability of the sampling tube 9. The sealing ring between the fixing plate 10 and the mounting plate 11 is made of high-temperature resistant and corrosion-resistant rubber material, which can effectively prevent material leakage inside the reactor and ensure the sealing and safety of the reactor. A connecting pipe 12 is fixedly connected to the bottom of the mounting assembly. A multi-way valve 13 is fixedly connected to the front side of the connecting pipe 12. The connecting pipe 12 acts as a bridge connecting the sampling tube 9 and the multi-way valve 13, and transports the material obtained from the sampling tube 9 to the multi-way valve 13. The operator can flexibly switch between different functional channels to complete a series of processes such as vacuuming before sampling, inert gas replacement, sample collection during sampling, and cleaning after sampling. The multi-way valve 13 is fixedly connected to an air inlet pipe 14 on its left side. An air inlet valve is installed at the top of the air inlet pipe 14. Before sampling, the air inlet valve is opened, and inert gas (such as nitrogen or argon) enters the sampling component through the air inlet pipe 14 and the multi-way valve 13, replacing the internal air and creating an inert environment to prevent oxidation, explosion, or other hazards caused by contact between the material and air, thus providing safety for the sampling operation. A drain pipe 15 is fixedly connected to the front of the multi-way valve 13, and a drain valve is installed at the top of the drain pipe 15. After sampling, the drain valve is opened, and cleaning fluid enters the sampling component through the drain pipe 15 to flush the sampling tube 9, connecting pipe 12, multi-way valve 13, and other components, removing residual material and impurities. The sample is discharged through the drain pipe 15, keeping the inside of the sampling assembly clean and preventing residual sample from contaminating the next sampling, thus ensuring the accuracy of the sampling results. A sampling pipe 16 is fixedly connected to the front of the multi-way valve 13. A safety valve is installed at the top of the sampling pipe 16. When the sample flows into the sampling container through the sampling pipe 16, the safety valve monitors the pressure inside the pipe in real time. When the pressure exceeds the safety threshold, the safety valve automatically opens to release pressure, preventing sample splashing due to excessive pressure inside the container, avoiding material leakage that could cause safety accidents and environmental pollution, and protecting the sampling pipe and other components from damage, ensuring safe and reliable sampling operations. A vacuum pipe 17 is fixedly connected to the right side of the multi-way valve 13. A vacuum valve is installed at the top of the vacuum pipe 17. Before sampling, the vacuum valve is opened.A vacuum device is connected to the sampling assembly to evacuate the internal air, creating a negative pressure environment. This facilitates subsequent replacement with inert gas, ensuring no residual air remains inside the sampling assembly and creating conditions for safe sampling. A fixing component is installed at the top of the sampling tube 9.
[0032] refer to Figure 3 and Figure 4 The fixing component includes a sampling port 19, the bottom of which is fixedly connected to the top of the sampling tube 9. A filter plate 20 is slidably connected to the inner wall of the sampling port 19. The filter plate 20 can be selected with a filter screen or sieve plate of appropriate pore size according to the material characteristics to filter the material entering the sampling tube 9, preventing solid particles, impurities, etc. from entering the sampling component and ensuring sample purity. Multiple top blocks 21 are slidably connected to the inner wall of the sampling port 19. The outer walls of the multiple top blocks 21 are slidably connected to the inner wall of the sampling port 19. A locking block 22 is fixedly connected to each adjacent side of the multiple top blocks 21. The outer walls of the multiple locking blocks 22 are slidably connected to the inner wall of the sampling port 19. The bottom side of the multiple locking blocks 22 contacts the top side of the filter plate 20. When installing the filter plate 20, the filter plate 20 is placed into the sampling port 19 and pressed. The locking blocks 22 will move outward under pressure. After the filter plate 20 is installed in place, the locking block 22 moves inward under the action of the return spring 25 and locks the top side of the filter plate 20, thereby enabling the filter plate 20 to be installed quickly and increasing the installation efficiency of the sampling assembly. The far sides of the multiple top blocks 21 are all fixedly connected to the transmission rods 23. The transmission rods 23 are fitted with return springs 25 on the outside and compression spring rings 24 are fixedly connected to the outside of the transmission rods 23. The near sides of the multiple return springs 25 are fixedly connected to the far sides of the multiple compression spring rings 24. The far sides of the multiple return springs 25 are fixedly connected to the outer inner wall of the sampling port 19. The far sides of the multiple transmission rods 23 are all fixedly connected to the pull plates 26. The near sides of the multiple pull plates 26 are in contact with the outer wall of the sampling port 19. Pulling the pull plates 26 can drive the transmission rods 23, causing the top blocks 21 and locking blocks 22 to move and release the fixation of the filter plate 20.
[0033] Working principle: During sampling, the sampling tube 9 is located at the bottom of the vessel 1, providing a positional guarantee for obtaining deep material samples inside the vessel. In the initial stage of sampling, the operator opens the vacuum valve at the top of the evacuation pipe 17, using the vacuum device to remove the air inside the sampling component and create a negative pressure environment. Then, the vacuum valve is closed, and the inlet valve on the inlet pipe 14 is opened. Inert gas is injected through the multi-way valve 13 to complete the internal air replacement and ensure sampling safety. When the preparation is complete, the sampling valve 18 outside the sampling tube 9 is opened. Driven by the pressure inside the vessel, the material flows through the sampling tube 9 and the connecting pipe 12 into the multi-way valve 13, and then flows into the sampling container through the sampling pipe 16. The safety valve at the top of the sampling pipe 16 can monitor the pressure in real time. When the pressure exceeds the safety threshold, it will automatically open to release the pressure and prevent sample splashing or pipe damage due to excessive pressure. After sampling is completed, the sampling valve 18 is closed, and the drain valve at the top of the drain pipe 15 is opened. The cleaning fluid is rinsed through the multi-way valve 13 to keep the inside clean and prepare for the next sampling.
[0034] To replace the filter plate 20, the operator only needs to pull the pull plate 26, which moves the transmission rod 23. The transmission rod 23 overcomes the elastic force of the return spring 25 and pulls the top block 21 to slide on the inner wall of the sampling port 19. The locking block 22 on the top block 21 then disengages from the filter plate 20, thereby releasing the fixation of the filter plate 20. The old filter plate 20 can be easily removed, and after the new filter plate 20 is placed, the pull plate 26 is released. The return spring 25 pushes the transmission rod 23 with the help of the compression spring ring 24, which drives the top block 21 and the locking block 22 to reset, so that the locking block 22 locks the filter plate 20 again, achieving a stable fixation. The operator can select a filter screen or sieve plate with a suitable aperture according to the material characteristics, and the maintenance difficulty of the sampling component is reduced.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
