The rotating tube 501 is movably installed with the kettle cover 2 through the bearing 504. The stirring assembly 5 also includes a mounting frame 509 and a stepper motor 507. The mounting frame 509 is fixedly connected to the kettle cover 2, and the stepper motor 507 is fixedly connected to the mounting frame 509. The output shaft of the stepper motor 507 is fixedly connected to the driving gear 508. The driving gear 508 and the driven gear 506 transmit to each other, so that the stepper motor 507 can easily operate the rotating tube 501 from the side to rotate. When the rotating tube 501 rotates, the L-shaped stirring plate 503 at the lower end of the rotating tube 501 synchronously stirs and mixes the materials. Since the side plates of the L-shaped stirring plate 503 are slidably connected to the inner wall of the kettle 1, the L-shaped stirring plate 503 is easy to remove the crystals on the inner wall of the kettle 1. When the L-shaped stirring plate 503 removes the crystals on the inside, it is easy to be contaminated with crystals.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the movable rod 510 is movably installed in the rotating tube 501, the lower end of the movable rod 510 is fixedly connected to a connecting block 511, two scrapers 512 are fixedly connected to the connecting block 511, and the L-shaped stirring plate 503 is located between the scrapers 512. The stirring component 5 also includes a movable groove 502, and the movable groove 502 is opened on both sides of the rotating tube 501. The connecting block 511 is movably installed in the movable groove 502, and the scraper 512 is located at the outer side of the rotating tube 501. The stirring component 5 also includes a spring 513 and a second limiting plate 514, and the second limiting plate 514 is fixedly connected to the upper end of the movable rod 510. The spring 513 is movably installed on the movable rod 510. , and is located between the No. 1 limit plate 505 and the No. 2 limit plate 514. The spring 513 pushes the No. 2 limit plate 514 upward, so that the movable rod 510 moves upward on the rotating tube 501, so that the connecting block 511 and the scraper 512 are easy to move upward, so that they are above the material. When the L-shaped stirring plate 503 removes the crystals on the inside of the kettle 1, the stepper motor 507 is stopped, and then the No. 2 limit plate 514 is pushed downward, so that the movable rod 510 moves downward, and the scraper 512 moves downward synchronously with the L-shaped stirring plate 503, scraping off the crystals on the surface of the L-shaped stirring plate 503, making it easier to remove the crystals on the L-shaped stirring plate 503.

[0023] It should be noted that the utility model is a crystallization kettle for preventing crystals from accumulating on the kettle wall. The material is fed into the kettle 1 through the feed pipe 3, and a valve is movably connected to the discharge pipe 4. Then the stepper motor 507 is started to rotate the driving gear 508. The driving gear 508 and the driven gear 506 are meshed and transmitted with each other. Through the driven gear 506, the rotating tube 501 is rotated on the kettle cover 2. The lower end of the rotating tube 501 is fixedly connected with an L-shaped stirring plate 503. The L-shaped stirring plate 503 synchronously stirs the material in the kettle 1 so that the material in the kettle 1 is mixed. The side of the L-shaped stirring plate 503 is connected to the inner wall of the kettle 1. As the L-shaped stirring plate 503 rotates, the L-shaped stirring plate 503 scrapes the inner wall of the kettle 1 so that the material in the kettle 1 is mixed. The crystals stuck on the upper surface are scraped off, and as the L-shaped stirring plate 503 scrapes, the inside of the kettle 1 is not easily stuck with crystals. However, the L-shaped stirring plate 503 is easily contaminated with a large amount of crystals. Therefore, after the crystals inside the kettle 1 are scraped off, the second limit plate 514 can be pressed downward to make the second limit plate 514, the movable rod 510, the connecting block 511 and the scraper 512 move downward synchronously, and the spring 513 is compressed by the downward moving second limit plate 514, the connecting block 511 moves downward in the movable groove 502, and the scraper 512 scrapes downward on the surface of the L-shaped stirring plate 503, thereby removing the crystals on the surface of the L-shaped stirring plate 503, making it easy to remove the crystals on the inner wall of the kettle 1 and the L-shaped stirring plate 503, and more convenient to use.
