Both the temperature sensor 30 and the pressure sensor 31 are electrically connected to the external controller.
[0034] When in use, first open the top cover 3, pour all the materials that need to undergo chemical reaction into the interior of the reactor body 2, then close the top cover 3, and seal the reactor body 2 and the top cover 3 through the connection between the two flanges 4. At the same time, through the cooperation between the sealing ring 28 and the sealing gasket 29, the reactor body 2 can have an excellent sealing environment, thereby reducing the leakage of materials and gases.

In this way, when the reactor body 2 is processing high-viscosity or solid-particle-containing materials, the scraper 24 can scrape the materials adhering to the inner wall of the reactor body 2, so that the materials can be returned to the reactor body 2 for uniform stirring, thereby greatly improving the stirring efficiency of the reactor body 2.

One end of the liquid outlet 35 is fixedly connected to the other end of the cooling pipe 33.
[0040] When in use, first connect the liquid inlet 34 and the liquid outlet 35 to the external circulation pump. Through the continuous operation of the circulation pump, the coolant inside the cooling pipe 33 can circulate. The circulation of the coolant can effectively cool the material inside the reactor body 2, and timely take away the huge heat generated by the chemical reaction, so as to keep the temperature of the material in the reactor stable, thereby improving the product quality.
[0041] The implementation principle of a high-temperature and high-pressure hydrothermal reactor in this embodiment is as follows: when in use, first open the top cover 3, pour all the materials that need to undergo chemical reaction into the interior of the reactor body 2, then close the top cover 3, and seal the reactor body 2 and the top cover 3 through the connection between the two flanges 4. At the same time, through the cooperation between the sealing ring 28 and the sealing gasket 29, the reactor body 2 can have an excellent sealing environment, thereby reducing the leakage of materials and gases. After the reactor body 2 is closed and sealed, the pressure pump 5 can be started to pressurize the interior of the reactor body 2, and the pressure gauge 6 and the pressure sensor 31 can be used to monitor the pressure in real time. When the specified value is reached, the pressure pump 5 can be turned off, and then the pressure can be The electric heating wire 14 is started to heat the inside of the reactor body 2, and the temperature is monitored in real time by the temperature sensor 30. When the specified temperature is reached, the electric heating wire 14 can be turned off to maintain the high pressure and high temperature inside the reactor body 2. Then, the servo motor 8 can be started to drive the connecting shaft 9 and the multiple connecting plates 10 at the bottom to rotate continuously. Through the rotation guidance of the connecting plate 10, the connecting rod 11 drives the stirring blade 12 to quickly stir the reaction materials inside the reactor body 2, so that the materials can be mixed evenly and the chemical reaction between the materials can be better carried out. In this way, the materials in the reactor can be heated while the mixed materials are stirred, realizing the perfect combination of stirring, heating and pressure control; Secondly, with the continuous rotation of the multiple connecting plates 10, the fixing rod 16 at the top will be driven to move together, and because the sub-gear 17 is meshed and connected with the main gear 15, when the fixing rod 16 follows the movement of the connecting plate 10, the sub-gear 17 will be driven to keep in contact with the main gear 15, so that the sub-gear 17 will continue to rotate, and the rotation of the sub-gear 17 will drive the fixing rod 16 and the sub-gear 2 18 at the bottom to rotate together, because the sub-gear 2 18 is meshed and connected with the sub-gear 3 20, when the sub-gear 2 18 rotates, the sub-gear 3 20 will be driven to rotate together, and the rotation of the sub-gear 3 20 and the guidance of the support rod 19 will drive the rotating plate 21 at the bottom to rotate, and at this time, the rotation of the rotating plate 21 will drive the multiple groups of connecting rods 2 22 and stirring blades 2 23 at the bottom of the multiple connecting plates 10 to rotate and stir, and the multiple groups of stirring blades 2 23 will be driven to rotate and stir. The cooperation between the stirring blade 23 and the stirring blade 12 can effectively expand the stirring range and increase the stirring stroke, so as to ensure that all materials in the reactor can be fully stirred, thereby improving the uniformity of mixing, and the heat and mass transfer between the materials can be strengthened by the enhanced stirring, so that the reaction speed is accelerated and the production efficiency is improved. With the rotation of the multiple groups of stirring blades 23, the multiple scrapers 24 can cyclically scrape the inner wall of the reactor body 2, and through the elasticity of the spring 26, the scraper 24 can be pushed by the sealing block 27 to always fit the inner wall of the reactor body 2. In this way, when the reactor body 2 is processing high-viscosity or solid-particle materials, the scraper 24 can scrape the materials adhering to the inner wall of the reactor body 2, so that the materials can be returned to the reactor body 2 for uniform stirring, which greatly improves the stirring efficiency of the reactor body 2. In addition, when the stirring is finished, the connection between the reactor body 2 and the top cover 3 can be released to release the pressure inside the reactor body 2. At this time, the logistics after the full reaction inside the reactor body 2 and the reactor body 2 will be in a high temperature state. Therefore, the liquid inlet 34 and the liquid outlet 35 can be connected to the external circulation pump. Through the continuous operation of the circulation pump, the coolant inside the cooling pipe 33 can circulate. The circulation of the coolant can effectively cool the material inside the reactor body 2 to timely take away the huge heat generated by the chemical reaction, and keep the temperature of the material in the reactor stable, thereby improving the product quality. After waiting for the cooling to end, the internal material can be taken out.
