[0028] By adopting the above technical solution, when using the device, firstly, the quantitatively proportioned raw materials are put into the mixing barrel 100 through the feeding port 110, and then the driving part 300 drives the stirring frame 200 to rotate to stir the raw materials evenly; after the stirring is completed, the discharge port 120 is opened to introduce the raw materials into the reactor to synthesize the organic polymer material; finally, the air pump 500 is opened to provide high-pressure gas to the jet part 400, and at the same time, the stirring frame 200 drives the jet part 400 to rotate, so that the jet part 400 can spray high-pressure gas to the circumferential inner wall of the mixing barrel 100, blow down the raw materials adhering to the inner wall of the mixing barrel 100, and introduce them into the reactor through the discharge port 120.
