[0026] The features and exemplary embodiments of various aspects of the utility model will be described in detail below. In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the utility model, rather than to limit the utility model. For those skilled in the art, the utility model can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the utility model by showing examples of the utility model.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the utility model provides a polymerization reaction device, which includes a sealing cover 1, a lifting device 2, a first kettle body 3 with an opening upward, a second kettle body 4 with an opening upward, a first rotating device 5, a heating device and a vacuum degree adjusting device. The lifting device 2 can drive the sealing cover 1 to lift vertically, and a holding device 6 for holding raw materials is installed at the bottom of the sealing cover 1; the heating device can heat the first kettle body 3, and the vacuum degree adjusting device can adjust the vacuum degree in the first kettle body 3. The first kettle body 3 and the second kettle body 4 are installed on the top of the first rotating device 5, and the first rotating device 5 can drive the first kettle body 3 and the second kettle body 4 to rotate horizontally around its axis, so that the first kettle body 3 or the second kettle body 4 can be moved from other positions to a closed position. Among them, the sealing cover 1 driven downward by the lifting device 2 can seal the opening of the first kettle body 3 or the opening of the second kettle body 4 moved to the closed position; the sealing cover 1 driven upward by the lifting device 2 can drive the holding device 6 to take off the first kettle body 3 or the second kettle body 4.

[0028] Specifically, the holding device 6 can hold the raw materials that have been stirred and mixed. The first rotating device 5 drives the first kettle body 3 to rotate to the closed position, and then the lifting device 2 drives the sealing cover 1 downward so that the holding device 6 extends into the first kettle body 3, and the sealing cover 1 is sealed at the opening of the first kettle body 3. Then the vacuum adjustment device evacuates the first kettle body 3. When the vacuum degree in the first kettle body 3 reaches the preset vacuum degree, the heating device heats the first kettle body 3 so that the raw materials in the holding device 6 undergo a polymerization reaction and produce a solid target product. When the reaction is complete, the heating device is turned off, and after the first kettle body 3 is cooled to a preset temperature, the vacuum adjustment device inflates the first kettle body 3 so that the air pressure in the first kettle body 3 reaches normal pressure. Then the lifting device 2 drives the sealing cover 1 and the holding device 6 to rise so that the sealing cover 1 and the holding device 6 are separated from the first kettle body 3. Then the first rotating device 5 rotates horizontally, the first kettle body 3 leaves the closed position, and the second kettle body 4 rotates to the closed position. The second kettle body 4 is filled with a reaction liquid that dissolves the target product. Then the lifting device 2 drives the sealing cover 1 and the containing device 6 to move downward, the containing device 6 extends into the second kettle body 4, and the sealing cover 1 seals the opening of the second kettle body 4. Then the reaction liquid in the second kettle body 4 can dissolve the target product, so that the target product completes the next stage of reaction.

[0029] In this embodiment, after the raw materials undergo a polymerization reaction in the first kettle body 3 to generate a solid target product, with the cooperation of the first rotating device 5 and the lifting device 2, the solid target product can directly enter the second kettle body 4 for dissolution without crushing the solid target product, which simplifies the process of applying the solid target product to the reaction liquid and also helps to simplify the entire process.

[0030] In addition, the lifting device 2 drives the sealing cover 1 downward so that the sealing cover 1 can be pressed against the opening of the first kettle body 3, which helps to maintain the sealing inside the first kettle body 3. Moreover, since there is no relative movement between the sealing cover 1 and the first kettle body 3, it also helps to maintain the sealing inside the first kettle body 3.

[0031] It should be noted that all the raw materials can be stirred and mixed in another kettle, and then the mixed materials are transported to the containing device 6 by a pumping device.

When the raw materials in the containing device 6 have finished reacting, the driving device drives the lifting rod 21 to rise so that the sealing cover 1 and the containing device 6 rise to the top of the first kettle body 3. Then the first rotating device 5 rotates to rotate the first kettle body 3 to a closed position. Then the driving device drives the lifting rod 21 to descend so that the containing device 6 is located in the second kettle body 4, and the sealing cover 1 is sealed at the opening of the second kettle body 4.
