Technical Field

[0001] The present application relates to the technical field of crystallizers, and in particular to a crystallizer with an inner wall that is easy to clean. Background Art

[0002] The crystallizer is an important device for preparing melamine. Since the crystallization time is generally long, the material will adhere to the inner wall of the crystallizer during crystallization, which will not only affect the temperature propagation of the crystallizer, but also the crystal layer will become thicker after long-term accumulation, making it inconvenient to clean the inner wall of the crystallizer. Therefore, the inventors proposed a crystallizer that is easy to clean the inner wall. Utility Model Content

[0038] In this embodiment, the crystallizer for facilitating cleaning of the inner wall includes a rotating shaft 40 arranged on the axis of the tank body 30, and a first scraper ring 10 and a second scraper ring 20 are sleeved on the rotating shaft 40. The first scraper ring 10 is screwed together with the rotating shaft 40, and the first scraper ring 10 is slidably engaged with a first slide groove 31 formed on the inner wall of the tank body 30, and the second scraper ring 20 is slidably engaged with a second slide groove 42 formed on the rotating shaft 40. The second scraper ring 20 is rotatably engaged with the first scraper ring 10, and scraping teeth 25 are provided on the circumferential surface of the second scraper ring 20.

[0039] In this embodiment, the first scraper ring 10 is driven to slide up and down along the axis of the tank body 30 by the forward and reverse rotation of the rotating shaft 40, and the second scraper ring 20 is driven to move up and down with the first scraper ring 10 while rotating synchronously with the rotating shaft 40. The circumferential surface of the first scraper ring 10 and the second scraper ring 20 is utilized to scrape off the crystal layer on the inner wall of the tank body 30, thereby improving the efficiency of cleaning the crystal layer.

[0040] It should be noted that a motor 41 is fixedly connected to the top of the tank body 30, and the rotating shaft 40 is connected to the output end of the motor 41. The motor 41 is used to drive the rotating shaft 40 to rotate forward or reversely. The first slide groove 31 is formed on the inner wall of the tank body 30, and the first slide groove 31 as a whole is arranged parallel to the axis of the tank body 30, and the first slide groove 31 is evenly distributed along the circumference of the tank body 30.

[0041] In addition, the first scraper ring 10 is arranged coaxially with the rotating shaft 40 as a whole, and the circumferential surface of the first scraper ring 10 is in contact with the inner wall of the tank body 30. A first sleeve 11 that is screwed with the rotating shaft 40 is provided at the axis of the first scraper ring 10. A first connecting plate 12 is fixedly connected between the first sleeve 11 and the first scraper ring 10, and the first connecting plate 12 is arranged along the radial direction of the first scraper ring 10 as a whole. The first connecting plates 12 are evenly distributed along the circumference of the first scraper ring 10. The first connecting plate 12 is used to connect the first scraper ring 10 and the first sleeve 11 into an integral structure. At the same time, a first clip 13 that is slidably engaged with the first slide groove 31 is provided on the circumferential surface of the first scraper ring 10, and the first clip 13 is in one-to-one correspondence with the first slide groove 31. A third clip groove 14 is also provided on the inner wall of the first scraper ring 10. The third clip groove 14 is constructed into a ring that is coaxially arranged with the first scraper ring 10, and the third clip groove 14 is arranged above the first connecting plate 12 as a whole.

[0042] In addition, the second scraper ring 20 is arranged coaxially with the rotating shaft 40 as a whole, and the circumference of the second scraper ring 20 is in contact with the inner wall of the tank body 30. A second sleeve 21 sleeved with the rotating shaft 40 is provided at the axis of the second scraper ring 20. The second sleeve 21 is slidably engaged with the rotating shaft 40 as a whole. A second card groove 41 is formed on the surface of the rotating shaft 40, and the second card groove 41 is arranged parallel to the axis of the rotating shaft 40.
