Description

Technical Field

[0001] The utility model relates to the technical field of lithium precipitation mother solution processing, in particular to a solution filter for lithium precipitation mother solution. Background Art

[0002] The formation and existence of lithium resources in nature are diverse, but they mainly exist in two forms: solid lithium ore and liquid lithium resources. Among liquid lithium resources, salt lake brine accounts for the largest proportion, of which salt lake brine lithium resources account for about 70% of the world's reserves. In the process of extracting lithium chloride from brine to produce lithium carbonate by membrane separation, the lithium precipitation mother liquor contains a considerable amount of lithium ions after the lithium precipitation reaction. If it is treated as wastewater, it will have a huge impact on the environment. At the same time, the lithium precipitation mother liquor is filtered and processed to remove the solid phase crystals for membrane concentration.

[0003] After searching, Chinese patent publication (announcement) No. CN 213913166 U discloses a solution filtering device for circulating lithium precipitation mother liquor. By providing a drainage groove on the inner wall of the filter bucket, when the filter membrane filters the lithium precipitation mother liquor, the contact area between the filter membrane and the filter bucket is reduced, so that when the solution is filtered through the filter membrane, it can not only be discharged through the liquid outlet, but also the filtered solution can be discharged into the drainage groove, and finally discharged from the liquid outlet through the drainage channel, thereby improving the efficiency of solution filtration. However, the current filtering device uses precipitation as a precipitation method. Since there is more liquid in the tank body, precipitation will cause the filtration time to be too long, affecting the efficiency. At the same time, the current device does not have a cleaning function. Long-term filtration will cause impurities to adhere to the inner wall of the tank body and cannot be cleaned. Therefore, it is necessary to design a solution filter for lithium precipitation mother liquor. Utility Model Content
