Description

Technical Field

[0001] This utility model relates to the field of crystallizer technology, and in particular to a mechanical scraper assembly for automatic cleaning of the inner wall of a crystallizer. Background Technology

[0002] Crystallizers are the core equipment for achieving solution crystallization. They control supersaturation to induce solute crystallization and are widely used in industries such as chemical and pharmaceutical manufacturing. Their functions include regulating temperature and pressure to promote crystallization and using stirring to ensure uniform crystal growth. They come in various structures, such as batch-type and vacuum-type. The working principle varies depending on the type; for example, vacuum crystallizers use negative pressure evaporation and cooling to increase supersaturation. The design must consider heat transfer, flow field, and scale prevention, making it a crucial piece of equipment for industrial crystallization.

[0003] In existing technologies, crystallizers typically have an internal scraper assembly. A motor drives the scraper assembly to rotate, and the mechanical scraper scrapes the inner wall of the crystallizer. During this scraping process, the mechanical scraper removes salt crystals adhering to the inner wall of the crystallizer, which are then discharged through a discharge assembly at the bottom of the crystallizer. This facilitates cleaning the inside of the crystallizer. While this device can quickly and conveniently clean the inside of the crystallizer, over long-term use, a large number of crystals may accumulate inside. The crystals scraped off by the mechanical scraper assembly may be large, and these larger crystals may be difficult to discharge directly through the discharge assembly. In such cases, a secondary cleaning of the device is required, affecting work efficiency.

[0004] Therefore, it is necessary to provide a new mechanical scraper assembly for automatic cleaning of the inner wall of the crystallizer to solve the above-mentioned technical problems. Utility Model Content

Connecting rods 4 are provided on both sides of the drive cleaning component. The roller 2 and the scraper 3 are respectively movably connected to the outside of the two connecting rods 4, and the roller 2 is rotatably connected to the connecting rods 4. The scraper 3 is fixedly connected to the connecting rods 4. The two connecting rods 4 are inclined. The filter plate 1 is fixedly installed inside the crystallizer body 14. One side of the roller 2 and the scraper 3 are attached to one side of the filter plate 1. The filter plate 1 is concave on one side and has multiple filter holes 5.

[0020] It should be noted that when the above device is in use, the drive motor 8 drives the rotating rod 6 and the mounting rod 7 to rotate together. During the rotation of the mounting rod 7, the mounting rod 7 drives the two connecting rods 4 to rotate synchronously. When the two connecting rods 4 rotate, they will drive the roller 2 and the scraper 3 to rotate. When the roller 2 rotates, it can crush large impurities. The crushed impurities are driven by the scraper 3 to move on the filter plate 1. When the impurities move to the filter hole 5, they will leak into the discharge cylinder 15 at the bottom of the crystallizer body 14 for cleaning. When this device is in use, it can not only scrape the inner wall of the crystallizer, making the crystallizer have a self-cleaning function, but also crush the large impurities scraped off, making it easier to clean and speeding up the work efficiency.

[0021] The drive cleaning assembly includes: a driver assembly, a rotating rod 6, a mounting rod 7, and multiple cleaning rod assemblies. One side of the driver assembly is fixedly connected to one side of the crystallizer body 14, and the output end of the driver assembly is fixedly connected to one side of the rotating rod 6. The other side of the rotating rod 6 passes through one side of the crystallizer body 14, and the rotating rod 6 is rotatably connected to the crystallizer body 14. The mounting rod 7 is fixedly mounted on the outside of the rotating rod 6, and multiple cleaning rod assemblies are respectively fixedly mounted on the outside of the mounting rod 7. Two connecting rods 4 are fixedly and obliquely connected to both sides of the mounting rod 7. The driver assembly includes: a drive motor 8 and a mounting bracket 9. One side of the mounting bracket 9 is fixedly connected to one side of the crystallizer body 14, and one side of the drive motor 8 is connected to the mounting bracket 9 away from the crystallizer body 14. 4. One side is fixedly connected, and the output end of the drive motor 8 is fixedly connected to one side of the rotating rod 6. The cleaning rod assembly includes: mounting cylinder 10, connecting cylinder 11, spring 12 and scraper 13. One side of the mounting cylinder 10 is fixedly connected to one side of the mounting rod 7. One side of the spring 12 is fixedly connected to the inside of the mounting cylinder 10. The other side of the spring 12 is fixedly connected to one side of the connecting cylinder 11. The side of the connecting cylinder 11 away from the spring 12 is fixedly connected to one side of the scraper 13. The side of the scraper 13 away from the connecting cylinder 11 is in contact with the inner wall of the crystallizer body 14. The connecting cylinder 11 extends into the interior of the mounting cylinder 10. The side of the scraper 13 near the crystallizer body 14 is arc-shaped. The cross-section of the mounting cylinder 10 and the connecting cylinder 11 is circular.

[0022] It should be noted that when the above-mentioned device is in use, when the drive motor 8 drives the rotating rod 6 and the mounting rod 7 to rotate, the mounting rod 7 will also drive the mounting cylinder 10 to rotate synchronously. When the mounting cylinder 10 rotates, it will drive the connecting cylinder 11 and the scraper 13 to rotate synchronously. One side of the scraper 13 is in contact with the crystallizer body 14. Therefore, when the scraper 13 rotates, it can scrape the inner wall of the crystallizer body 14. The mounting cylinder 10 and the connecting cylinder 11 are connected by a spring 12. In the initial state, the spring 12 provides elasticity so that the connecting cylinder 11 squeezes the scraper 13 into contact with the inner wall of the crystallizer body 14. In use, the scraper 13 can apply pressure to the inner wall of the crystallizer body 14 while scraping, making the cleaning more thorough. The edge of the scraper 13 is set to be arc-shaped, so that when the scraper 13 comes into contact with the inner wall of the crystallizer body 14, the scraper 13 will not damage the inner wall of the crystallizer body 14. This makes the device not only cleaner but also has a longer service life.
