[0018] Example 1 Please see Figure 1-4 As shown, a dispersion vessel for polyurethane production includes a support frame 1, and a vessel body 2 is fixedly fixed through the inside of the support frame 1. A feed pipe 3 is connected to the upper part of the outer surface of the vessel body 2, and a discharge pipe 7 is connected to the center of the bottom of the vessel body 2. A pipe cap 8 is threadedly connected to the lower part of the outer surface of the discharge pipe 7. The reactor body 2 is equipped with a cover plate 5. A motor 4 is fixedly installed on the top of the cover plate 5. A rotating rod 11 is fixedly installed at the output end of the motor 4. Multiple evenly distributed stirring rods 12 are fixedly connected to the lower outer surface of the rotating rod 11. During operation, when polyurethane raw material dispersion is required, polyurethane raw material and water are poured into the reactor body 2 through the feed pipe 3 in proportion. Then, the motor 4 is started, and the motor 4 drives the rotating rod 11 to rotate. The multiple stirring rods 12 on the rotating rod 11 rotate accordingly, which fully stirs and mixes the polyurethane raw material and water in the reactor body 2, so that it is quickly dispersed. After the dispersion operation is completed, the pipe cover 8 is opened, and the dispersed polyurethane is discharged from the discharge pipe 7.

[0019] An electric telescopic rod 14 is fixedly installed on the outer surface of the rotating rod 11 between every two stirring rods 12. A scraper 13 is fixedly installed at the output end of the electric telescopic rod 14. During operation, the electric telescopic rod 14 is activated during the stirring and dispersion process. The electric telescopic rod 14 drives the scraper 13 to move and come into contact with the inner wall of the vessel body 2. After the scraper 13 comes into contact with the inner wall, it rotates by the rotation of the rotating rod 11, which can scrape off the polyurethane adhering to the inner wall of the vessel body 2, thus avoiding long-term accumulation that affects product quality.

[0020] The scraper 13 is configured in an arc shape, and the outer surface of the scraper 13 is in contact with the inner wall of the vessel body 2.
