Through research and analysis, it is found that although it has the advantage of convenient cleaning of the inside of the device, it still has the following disadvantages to a certain extent.

[0004] For example, the cooling pipe used for cooling is set inside the kettle body, and is not placed in the inner cavity of the kettle body so that it cannot contact the material, resulting in slow cooling speed and poor effect when cooling is required. At the same time, the stirring method is single and the upper and lower materials are uneven. In order to solve the above technical problems, we have designed a high-temperature and high-pressure reactor. Utility Model Content

[0021] The stirring mechanism 3 includes a motor 31 , a belt pulley 1 32 , a belt pulley 2 33 , a belt 34 , a stirring paddle 35 , a cylinder 36 and a spiral blade 37 , and the cooling mechanism 4 includes a rotating pipe 41 , a cooling pipe 42 , a liquid inlet pipe 43 and a liquid outlet pipe 44 .

[0022] See also Figure 2 and Figure 3 The upper end of the rotating tube 41 is rotatably embedded in the top of the kettle cover 2 through a sealed bearing, and the lower end of the rotating tube 41 is rotatably embedded in the bottom of the kettle body 1 through a sealed bearing. The upper end of the liquid inlet pipe 43 is rotatably connected to the lower end of the rotating tube 41 through a sealed bearing, and the lower end of the liquid outlet pipe 44 is rotatably connected to the upper end of the rotating tube 41 through a sealed bearing. There are six cooling tubes 42, and their two ends are respectively connected to the surface of the rotating tube 41. By setting the cooling tube 42, when the coolant flows through it, the raw materials in the kettle body 1 are cooled, and the raw materials can be stirred when it rotates.

[0023] See also Figure 2 and Figure 3The surface of the motor 31 is fixedly connected to the rear side of the top of the kettle cover 2 through a support plate, the belt pulley 1 32 is fixedly sleeved on the surface of the rotating shaft of the motor 31, the belt pulley 2 33 is fixedly sleeved on the surface of the upper end of the rotating tube 41, and the belt 34 is driven by the belt pulley 1 32 and the belt pulley 2 33. By setting the belt pulley 1 32, the belt pulley 2 33 and the belt 34, the rotation of the rotating tube 41 is realized under the drive of the motor 31, and the rotation communication between the liquid outlet pipe 44 and the rotating tube 41 is not affected.

[0024] See also Figure 2 and Figure 3 The side of the stirring paddle 35 close to the cooling tube 42 is welded to the surface of the cooling tube 42, the surface of the cylinder 36 is welded to the surface of the cooling tube 42 through a support rod, and the spiral blade 37 is sleeved and welded on the surface of the rotating tube 41. By arranging the cylinder 36 and the spiral blade 37, the material in the lower part of the kettle body 1 is transported upward from the cylinder 36 under the rotation of the spiral blade 37, and then falls from the outside of the cylinder 36 to maintain circulation, thereby improving uniformity.

[0025] See also Figure 1 and Figure 2 A pressure relief valve 9 is installed on the right side of the top of the kettle cover 2. By setting the pressure relief valve 9, the pressure in the reactor is relieved to effectively avoid the danger of excessive pressure. A discharge valve 10 is installed on the left side of the bottom of the kettle body 1. By setting the discharge valve 10, the material in the reactor can be discharged conveniently.

[0026] See also Figure 1 and Figure 3 An observation window 11 is fixedly embedded on the front of the kettle body 1, and a feeding pipe 12 is connected to the left side of the top of the kettle cover 2. A sealing cover 13 is provided on the top threaded sleeve of the feeding pipe 12. A scraper 14 is welded on the surface of the lower end of the rotating tube 41.

[0027] When in use, the material is added to the kettle body 1 through the feeding pipe 12 and tightened through the sealing cover 13. The operation of the motor 31 is controlled to be driven by the belt pulley 1 32, the belt pulley 2 33 and the belt 34, so that the rotation of the rotating pipe 41, the cooling pipe 42, the stirring paddle 35, the cylinder 36 and the spiral blade 37 can stir the material to react, effectively improving the efficiency and uniformity of the reaction. At the same time, the rotation of the spiral blade 37 continuously transports the material at the bottom upward and then falls from the outside of the cylinder 36, effectively avoiding the unevenness caused by the sinking of the material. By externally connecting the liquid inlet pipe 43 and the liquid outlet pipe 44 The cooling circulation device heats the kettle body 1 by controlling the operation of the heater 6, thereby increasing the temperature of the raw material reaction. When the temperature sensor 7 detects a temperature value higher than the set temperature, it controls the operation of the cooling circulation device and the shutdown of the heater 6, and allows the coolant to enter the transfer pipe 41 and the cooling pipe 42 through the liquid inlet pipe 43, and then be discharged through the liquid outlet pipe 44. This can cool the raw material reaction and adjust the reaction temperature, effectively ensuring the temperature conditions required for the production reaction. The pressure in the reactor is monitored and displayed by the pressure gauge 8, so that the pressure inside the reactor is always known.
