Description

Technical Field

[0001] The invention relates to the technical field of magnesium sulfate production, in particular to a magnesium sulfate rotary flash crystallizer. Background Art

[0002] Magnesium sulfate is a magnesium-containing compound that can be used in leather making, explosives, papermaking, porcelain, fertilizer, and medical oral laxatives. Mineral water additive magnesium sulfate is used as a fertilizer in agriculture because magnesium is one of the main components of chlorophyll. It is usually used for potted plants or magnesium-deficient crops, such as tomatoes, potatoes, roses, etc. The advantage of magnesium sulfate over other fertilizers is its higher solubility. Magnesium sulfate is also used as bath salts.

[0003] At present, the main methods of magnesium sulfate crystallization are intermittent cooling crystallization and flash crystallization. Among them, in the flash crystallization method of magnesium sulfate, after a period of production, "scar-like" crystals will be hung on the inner wall of the crystallizer. The gradual accumulation of these "scar-like" crystals will seriously affect the crystallization efficiency and cause the flash crystallizer to fail to operate normally.

[0004] Therefore, the present invention proposes a magnesium sulfate rotary flash crystallizer to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] See also Figure 1 In an embodiment of the present invention, a magnesium sulfate rotary flash crystallizer is provided, wherein the rotary flash crystallizer comprises:

[0032] Base 2;

[0033] A flash crystallizer body 4 is disposed above the base 2, a mounting rod 3 is fixedly disposed on the base 2, and one side of the flash crystallizer body 4 is hinged to the mounting rod 3;

[0034] A pushing mechanism, provided on the base 2, is used to drive the flash crystallizer body 4 to rock back and forth during operation to improve the crystallization efficiency;

[0035] The wall scraping mechanism is arranged on the flash crystallizer body 4 and is used for scraping off the crystals adhering to the inner wall of the flash crystallizer body 4 .

[0036] In this embodiment, during the crystallization of magnesium sulfate, the flash crystallizer body 4 is driven to rock back and forth by the jacking mechanism to improve the crystallization efficiency. At the same time, the scraping mechanism scrapes off the crystals adhering to the inner wall of the flash crystallizer body 4 to avoid accumulation, thereby ensuring efficient crystallization of the flash crystallizer body 4.

[0037] Furthermore, in this embodiment, a plurality of moving wheels 1 are symmetrically provided at the bottom of the base 2 to facilitate the overall movement of the rotary flash crystallizer.

[0038] See also Figure 1 to Figure 3 In one embodiment of the present invention, the jacking mechanism comprises:

[0039] A box body 13 is fixed on the base 2, a push rod 16 is movably provided on the top of the box body 13, a flower-shaped block 14 is rotatably provided in the box body 13, a slot 12 is provided at the bottom of the flash crystallizer body 4, a rolling wheel 15 is fixed at the lower end of the push rod 16, the rolling wheel 15 abuts against the side of the flower-shaped block 14, and the upper end of the push rod 16 is stuck in the slot 12;

[0040] The box body 14 is fixedly provided with a driving motor (not shown in the figure) for driving the flower-shaped block 14 to rotate.

[0041] In this embodiment, the flower-shaped block 14 is driven by a driving motor to rotate, and the rotation of the flower-shaped block 14 drives the top rod 16 to move up and down in a circular motion, and the up and down circular motion of the top rod 16 drives the flash crystallizer body 4 to rock back and forth, thereby improving the crystallization efficiency of magnesium sulfate.

[0042] See also Figure 1 and Figure 4 In one embodiment of the present invention, the wall scraping mechanism comprises:

[0043] An annular scraper plate 6 having the same contour as the inner cavity of the flash crystallizer body 4 is arranged in the flash crystallizer body 4. A threaded rod 5 is rotatably arranged in the flash crystallizer body 4. The threaded rod 5 threadably penetrates the annular scraper plate 6.

[0044] The annular scraper plate 6 is provided with a plurality of through holes 10 evenly arranged in an annular direction, and each of the through holes 10 is provided with a disturbance boss 11;

[0045] A rotating rod 8 is rotatably disposed in the flash crystallizer body 4, and a plurality of stirring blades 9 are evenly disposed on the rotating rod 8. The rotating rod 8 and the threaded rod 5 are linked via a belt transmission structure 17.

[0047] In this embodiment, the rotating motor 7 drives the rotating rod 8 to rotate forward and reversely in a circular motion. Under the linkage action of the belt transmission structure 17, the rotating rod 8 drives the threaded rod 5 to rotate forward and reversely in a circular motion. The forward and reverse rotation of the threaded rod 5 drives the scraping annular scraper plate 6 to scrape up and down along the inner wall of the flash crystallizer body 4 to scrape off the crystals adhered to the inner wall of the flash crystallizer body 4. While the rotating rod 8 rotates, it also drives multiple stirring blades 9 to continuously stir the crystallization solution. While the annular scraper plate 6 scrapes up and down in a circular motion, the crystallization solution passes through the through hole 10, and the disturbance boss 11 further disturbs the crystallization solution, thereby improving the crystallization efficiency.

[0048] Furthermore, in this embodiment, a protective film (not shown in the figure) is attached to the side of the annular scraper plate 6 that contacts the inner wall of the flash crystallizer body 4 to avoid scratching the inner wall of the flash crystallizer body 4 .

[0049] In the above embodiment of the present invention, a magnesium sulfate rotary flash crystallizer is provided. During the crystallization process of magnesium sulfate, the flash crystallizer body 4 is driven to swing back and forth by the jacking mechanism to improve the crystallization efficiency. At the same time, the scraping mechanism scrapes off the crystals adhering to the inner wall of the flash crystallizer body 4 to avoid accumulation, thereby ensuring efficient crystallization of the flash crystallizer body 4.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
