Description

Technical Field

[0001] The utility model relates to the technical field of aluminum fluoride crystallization, in particular to an aluminum fluoride crystal cultivation device. Background Technique

[0002] In the field of aluminum fluoride production, when aluminum fluoride liquid crystallizes in a crystallization tank, the temperature needs to be controlled between 80 and 100 degrees Celsius to improve the filtration efficiency. However, when using the method of natural sedimentation for concentration, crystals will deposit on the bottom and side walls of the crystal cultivation tank.

[0003] For example, a novel crystal cultivation device for aluminum fluoride crystallization disclosed in the Chinese authorized patent CN213221028 U realizes the stirring of materials to accelerate crystallization through a retractable scraper structure. At the same time, the scraper can also scrape the filter screen to clean the crystal aluminum fluoride. Further, by manually pulling out the hole plug, the crystals are discharged.

[0004] To a certain extent, the above device achieves the purpose of facilitating the cleaning of crystals, but there are still deficiencies. First, its scraper can only scrape the crystals on the filter screen. Obviously, the inner wall of the box will also crystallize, and there is no cleaning mechanism for this part of the crystals. Moreover, the freshly crystallized aluminum fluoride still carries a certain amount of moisture and is prone to adhesion during subsequent transportation. Second, the operation of discharging crystals by manual means is obviously labor-consuming, and the degree of automation needs to be improved. Content of the Utility Model
