[0022] Such as Figures 1 to 5As shown in the figure, the reaction kettle for rapid heating in this embodiment includes a kettle body 1. Inside the kettle body 1, there is a reaction chamber 2 for the reaction of raw materials. On the inner wall of the kettle body 1, there is a heating chamber 3. Inside the heating chamber 3, a heating medium 4 is placed. By heating the heating medium 4, the heating medium 4 can heat the outside of the reaction chamber 2 for protection. The heating medium 4 can be water or grease. On the inner wall of the kettle body 1 outside the heating chamber 3, a heat preservation layer 5 is installed. The setting of the heat preservation layer 5 effectively avoids the transfer of heat through the kettle body 1 and the loss of heat, and effectively improves the heating efficiency of the reaction kettle. Inside the reaction chamber 2, heating tubes 6 are symmetrically installed at the front and rear. On the surface of each heating tube 6, a number of heat conduction tubes 7 are installed. One end of each heat conduction tube 7 extends into the heating chamber 3. The heating tubes 6 are used to heat the inside of the heating chamber 3, and the heat conduction tubes 7 are used to heat the heating medium 4 inside the heating chamber 3. At the upper end of the kettle body 1, a kettle cover 8 is installed in a liftable manner. A stirring assembly is installed on the kettle cover 8. By lifting the kettle cover 8, the kettle cover 8 can drive the stirring assembly to lift, which is convenient for cleaning the inside of the reaction chamber 2 and avoiding the formation of a dirt layer inside the reaction layer, which affects the heat exchange efficiency. At the lower end of the kettle body 1, a discharge pipe 10 is installed, and at the upper end of the kettle cover 8, an addition pipe 11 is installed.

[0023] Specifically, a fixed ring 12 is installed at the lower end of the kettle cover 8. Below the fixed ring 12, a contact groove 13 is arranged on the upper end of the kettle body 1. A sealing gasket 14 is installed at the lower end of the fixed ring 12. Both the sealing gasket 14 and the fixed ring 12 are located inside the contact groove 13.

The lower end of the clamping plate 19 is in contact with the upper end of the fixing plate 24. By rotating the bolt 18 to drive the clamping plate 19 to descend, the clamping plate 19 and the fixing plates 24 on both sides of the kettle cover 8 are pressed, and the fixing of the kettle cover 8 can be realized.

[0026] Furthermore, a rotating shaft 20 is installed at the lower end of the fixing frame 17. The rotating shaft 20 is installed inside the connecting plate 15 through a through hole. By rotating the fixing frame 17 to drive the rotating shaft 20 to rotate, it is convenient to move the fixing frame 17 away from above the connecting plate 15 to avoid hindering the movement of the fixing plate 24.

[0027] Even further, mounting plates 21 are installed on the surfaces of the kettle body 1 below the connecting plates 15. Electric push rods 22 are installed at the upper ends of the mounting plates 21. Circular holes 23 are arranged through the lower ends of the connecting plates 15 above the electric push rods 22. By extending the electric push rods 22 through the circular holes 23 to contact the fixing plates 24 on both sides of the kettle cover 8, it is convenient to drive the kettle cover 8 and the stirring assembly to rise, facilitating the flushing of the stirring assembly and the inside of the reaction chamber 2.

[0028] The usage method of this embodiment is as follows: When using this quickly heated reaction kettle, raw materials are added into the reaction chamber 2 inside the kettle body 1 through the adding pipe 11, and then the heating tube 6 is controlled to heat. The heating tube 6 can heat the raw materials. At the same time, the heating tube 6 heats the heating medium 4 inside the heating chamber 3 through the heat conduction tube 7. The heating medium 4 keeps a certain temperature on the surface of the kettle body 1, effectively avoiding heat loss through the kettle body 1. At the same time, the stirring motor 901 drives the stirring shaft 902 and the stirring rods 903 to stir the raw materials, facilitating the uniform heating of the raw materials and enabling the raw materials to react inside the reaction chamber 2. After the use of the kettle body 1 is completed, the reacted raw materials are discharged through the discharge pipe 10. Then, by rotating the bolt 18 to drive the clamping plate 19 to rise, the clamping plate 19 does not fix the fixing plates 24 on both sides of the kettle cover 8, and the fixing frame 17 is rotated to move the fixing frame 17 away from above the fixing plate 24. The electric push rod 22 is controlled to extend. The electric push rod 22 drives the kettle cover 8 to rise through the fixing plate 24, facilitating the flushing of the stirring assembly on the kettle cover 8 and the inside of the reaction chamber 2, and avoiding the formation of a dirt layer inside the stirring assembly and the reaction chamber 2, which affects the heat exchange efficiency of the reaction kettle.
