A receiving ring 21 is installed on the inner wall of the jacket 2, an annular groove 22 is opened on the receiving ring 21, a sealing gasket 23 is assembled in the annular groove 22. A kettle body 24 is installed on the jacket 2, a heating layer 25 is arranged between the kettle body 24 and the jacket 2, a feed pipe 26 and a discharge pipe 27 are installed on the side wall of the jacket 2, a discharge pipe 28 is installed on the bottom side of the kettle body 24, and a valve 29 is installed on the discharge pipe 28. A support seat 30 is installed on the cover body 4, a motor 31 is installed on the support seat 30, a stirring rod 32 is installed on the output shaft of the motor 31, and stirring blades 33 are installed on the stirring rod 32. A feeding pipe 34 is installed on the cover body 4, and a sealing cover 35 is rotatably installed on the feeding pipe 34 through a hinge. During operation, the existing reactor is usually an integral structure to ensure tightness. Since the reactor cannot be disassembled, during the cleaning process, it is necessary to work repeatedly and rinse many times, resulting in poor disassembly and assembly performance of the reactor and affecting the cleaning efficiency of the reactor. By opening the sealing cover 35, the material is put into the kettle body 24 from the feeding pipe 34. Then, through the operation of the motor 31, the stirring rod 32 is driven to rotate, and the stirring rod 32 drives the stirring blades 33 to rotate. The stirring blades 33 stir the mixed solution. At the same time, hot steam enters the heating layer 25 between the kettle body 24 and the jacket 2 from the feed pipe 26 and flows out through the discharge pipe 27. The hot steam circulates in the heating layer 25 and heats the kettle body 24. The stirring of the stirring blades 33 and the heating can accelerate the mixing rate of the mixed solution, improve the mixing effect, and make the mixed solution mix more thoroughly, realizing the preparation of the passivator;

[0020] During the internal cleaning process of the reactor, by rotating the knob 11, the rotating block 10 is driven to rotate. The rotating block 10 drives the screw 12 to rotate, and the screw 12 is screwed out from the first edge ring 3 of the jacket 2, realizing the disassembly of the jacket 2 and the cover body 4. After that, the inner wall of the kettle body 24 can be conveniently cleaned;

[0021] After the cleaning is completed, by placing the sealing gasket 23 in the annular groove 22 of the jacket 2, and then buckling the cover body 4 on the jacket 2, the screw 12 on the cover body 4 is aligned with the second rod groove 13 on the first edge ring 3. At this time, the screw 12 is inserted into the second rod groove 13. By rotating the knob 11, the rotating block 10 is driven to rotate. The rotating block 10 drives the screw 12 to rotate, and the screw 12 gradually screws into the second rod groove 13 of the first edge ring 3. During the process of the screw 12 screwing into the second rod groove 13, the screw 12 drives the second edge ring 5 to move downward, and the distance between the second edge ring 5 and the first edge ring 3 gradually decreases, so that the distance between the cover body 4 and the top of the jacket 2 gradually decreases. When the cover body 4 is buckled on the jacket 2, the second edge ring 5 on the cover body 4 presses down the measuring rod 15. Under the action of the spring 20, the spring 20 pushes the limiting block 19 to move upward, and the limiting block 19 drives the measuring rod 15 to move upward. Therefore, the top of the measuring rod 15 is always in contact with the second edge ring 5. As the screw 12 continuously screws into the second rod groove 13, the distance between the second edge ring 5 and the first edge ring 3 gradually decreases, the measuring rod 15 is continuously pressed downward, and the scale value of the comparison measuring tube 17 on the measuring rod 15 is also gradually changing. When the screw 12 is tightened, the scales on all the measuring rods 15 are adjusted to the same scale value, indicating that the cover body 4 and the jacket 2 are in a sealed state and the sealing performance is the same everywhere, avoiding the situation that the sealing performance of a certain place is unqualified. The purpose of sealing is to prevent the passivator from contacting with oxygen or other gases in the air, thereby preventing the passivator from oxidizing or deteriorating; this structure can disassemble the reactor while ensuring the sealing performance, which can improve the convenience of cleaning and is conducive to improving the disassembly and assembly performance of the reactor.

[0022] Working principle: The existing reaction kettle is usually an integral structure to ensure tightness. Since the reaction kettle cannot be disassembled, during the cleaning process, it is necessary to work repeatedly and rinse multiple times, resulting in poor disassembly and assembly performance of the reaction kettle and affecting the cleaning efficiency. By opening the cover 35, the material is put into the kettle body 24 through the feeding pipe 34. Then, through the operation of the motor 31, the stirring rod 32 is driven to rotate, and the stirring rod 32 drives the stirring blade 33 to rotate. The stirring blade 33 stirs the mixed solution. At the same time, the hot steam enters the heating layer 25 between the kettle body 24 and the jacket 2 through the feeding pipe 26, and the hot steam flows out through the discharging pipe 27. The hot steam circulates in the heating layer 25, and the hot steam heats the kettle body 24. The stirring of the stirring blade 33 and the heating can accelerate the mixing rate of the mixed solution, improve the mixing effect, make the mixed solution mix more thoroughly, and realize the preparation of the passivator; during the internal cleaning of the reaction kettle, by rotating the knob 11, the rotating block 10 is driven to rotate, and the rotating block 10 drives the screw rod 12 to rotate, and the screw rod 12 is screwed out from the first edge ring 3 of the jacket 2, realizing the disassembly of the jacket 2 and the cover body 4. Then, the inner wall of the kettle body 24 can be cleaned conveniently; after the cleaning is completed, by placing the sealing gasket 23 in the annular groove 22 of the jacket 2, and then buckling the cover body 4 on the jacket 2, so that the screw rod 12 on the cover body 4 is aligned with the second rod groove 13 on the first edge ring 3. At this time, the screw rod 12 is inserted into the second rod groove 13. By rotating the knob 11, the rotating block 10 is driven to rotate, and the rotating block 10 drives the screw rod 12 to rotate. The screw rod 12 gradually screws into the second rod groove 13 of the first edge ring 3. During the process of the screw rod 12 screwing into the second rod groove 13, the screw rod 12 drives the second edge ring 5 to move downward, and the distance between the second edge ring 5 and the first edge ring 3 gradually decreases, so that the distance between the cover body 4 and the top of the jacket 2 gradually decreases. When the cover body 4 is buckled on the jacket 2, the second edge ring 5 on the cover body 4 presses down the measuring rod 15. Under the action of the spring 20, the spring 20 pushes the limiting block 19 to move upward, and the limiting block 19 drives the measuring rod 15 to move upward. Therefore, the top of the measuring rod 15 is always in contact with the second edge ring 5. As the screw rod 12 continuously screws into the second rod groove 13, the distance between the second edge ring 5 and the first edge ring 3 gradually decreases, the measuring rod 15 is continuously pressed downward, and the scale value of the comparison measuring tube 17 on the measuring rod 15 also gradually changes. When the screw rod 12 is tightened, the scales on all the measuring rods 15 are adjusted to the same scale value, indicating that the cover body 4 and the jacket 2 are in a sealed state and the tightness is the same everywhere, avoiding the situation that the tightness is unqualified at a certain place. The purpose of sealing is to prevent the passivator from contacting with oxygen or other gases in the air, so as to prevent the passivator from oxidizing or deteriorating; this structure can disassemble the reaction kettle while ensuring tightness, can improve the convenience of cleaning, and is beneficial to improving the disassembly and assembly performance of the reaction kettle.
