Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0024] Please see Figures 1-5This utility model provides an embodiment of an antioxidant crystallization device, comprising a crystallization vessel 10. A feed pipe 15 is fixedly connected to the upper end face of the crystallization vessel 10, allowing a reducing agent raw material solution to be input into the inner cavity of the crystallization vessel 10 through the feed pipe 15. A motor 14 is fixedly installed on the upper end face of the crystallization vessel 10, and a rotating shaft 17 is fixedly connected to the output end of the motor 14. The rotating shaft 17 extends downwards and penetrates into the inner cavity of the crystallization vessel 10. A cylindrical portion 23 is fixedly installed at the bottom end of the rotating shaft 17, and the outer end face of the cylindrical portion 23 has... Inclined scrapers 24 are fixedly installed at intervals, and vertical scrapers 25 are fixedly installed on the upper surface of each inclined scraper 24. A partition 20 is fixedly installed in the inner cavity of the crystallization vessel 10. The triangular end of the vertical scraper 25 slides against the partition 20, so as to scrape off some crystals attached to the cavity wall and avoid residue. A sliding plate part 26 is slidably installed on the upper surface of the vertical scraper 25. A return spring is connected between the bottom end of the sliding plate part 26 and the bottom of the sliding cavity on the upper surface of the vertical scraper 25. An elastic arc-shaped strip 28 is fixedly connected between the vertical scraper 25 and the inclined surfaces on both sides. An installation ring 18 is fixedly installed on the inner wall of the partition 20. The bottom of the installation ring 18 has evenly spaced grooves 27. The top of the sliding plate 26 is slidably embedded in the groove 27. When the rotating shaft 17 rotates, it drives the inclined scraper 24 to rotate, thereby causing the vertical scraper 25 to rotate along the cavity wall of the partition 20, scraping away some crystals remaining on the cavity wall. Simultaneously, during rotation, the sliding plate... The slide portion 26 slides in the groove cavity 27, causing the slide plate portion 26 to slide up and down reciprocally. Since the upper end of the elastic arc strip 28 is fixed on the slide plate portion 26 and the lower end is fixed on the vertical scraper 25, when the slide plate portion 26 slides down, the elastic arc strip 28 will arch towards the inclined surfaces on both sides of the vertical scraper 25. Each arch will abut against the cavity wall of the partition 20. Thus, during the reciprocating arching and releasing process, the elastic potential energy of the elastic arc strip 28 can be used to effectively remove some highly adhesive crystals.

[0025] It is worth mentioning that, in order to further improve the efficiency of cooling the reducing agent and thus increase the crystallization speed, in this embodiment, a cooling pipe 21 is installed in the annular cavity between the partition 20 and the crystallization vessel 10. The head and tail ends of the cooling pipe 21 are connected to an external cooling water source. The cooling pipe 21 is looped around the partition 20, and the circulating cooling water is used to cool and crystallize the reducing agent solution inside.

[0026] It should be noted that, in this embodiment, a stirring element 19 is fixedly installed on the rotating shaft 17, and the stirring rods distributed on the stirring element 19 are arranged at an angle, which can continuously stir during crystallization and further improve the crystallization efficiency.

[0027] It is also worth mentioning that, in order to facilitate the separation between the crystals and the waste liquid after crystallization, in this embodiment, a support 12 is fixedly installed on the outer end face of the crystallization vessel 10, a filter cylinder 11 is fixedly installed on the inner side of the support 12, a drain pipe 16 is fixedly connected to the bottom of the filter cylinder 11, and a filter screen 13 is fixedly installed in the filter cylinder 11. When the switch valve 22 installed at the discharge port is opened, the waste liquid and the crystals enter the filter cylinder 11 together, while the crystals are intercepted and filtered by the filter screen 13, and the waste liquid is discharged through the drain pipe 16 at the bottom.

[0028] In practice, cooling water is first introduced into the cooling pipe 21, and then the reducing agent solution to be crystallized is introduced into the inner cavity of the crystallization vessel 10. At this time, the motor 14 is started to drive the rotating shaft 17 to rotate, which drives the stirring element 19 to stir the solution to accelerate crystallization. After crystallization is completed, the bottom switch valve 22 is opened to allow the precipitated crystals and waste liquid to enter the filter cylinder 11. At the same time, the rotating shaft 17 continues to rotate, which drives the inclined scraper 24 to rotate, thereby driving the vertical scraper 25 to rotate along the cavity wall of the partition 20, which can scrape off some crystals remaining on the cavity wall. During the rotation, the sliding plate part... The slide plate 26 slides in the groove cavity 27, causing the slide plate 26 to slide up and down repeatedly. Since the upper end of the elastic arc strip 28 is fixed on the slide plate 26 and the lower end is fixed on the vertical scraper 25, when the slide plate 26 slides down, the elastic arc strip 28 will arch towards the inclined surfaces on both sides of the vertical scraper 25. Each arch will abut against the cavity wall of the partition 20. In the process of reciprocating arching and releasing, the elastic potential energy of the elastic arc strip 28 can be used to effectively remove some highly adhesive crystals, thereby scraping off all the crystals attached to the inner cavity side wall of the crystallizing vessel 10, effectively avoiding residue.

[0029] It should be emphasized that the embodiments described in this utility model are illustrative and not limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
