Description

Technical Field

[0001] The utility model relates to the field of lithium fluoride drying, in particular to a lithium fluoride slurry washing and drying device. Background Art

[0002] Lithium fluoride is an inorganic compound that is slightly soluble in water. During the processing of lithium fluoride, it needs to be washed. Since lithium fluoride is extremely insoluble in water, water washing can effectively remove the chloride ions in it. After the lithium fluoride is washed, it needs to be dried with drying equipment.

[0003] Common lithium fluoride slurry washing and drying equipment only includes a drying function and can dry the washed lithium fluoride slurry, but lacks the function of circulating feeding and crushing. It cannot ensure that the lithium fluoride can be crushed during drying. It is easy for the lithium fluoride to need to be moved to the next process for crushing after spending a lot of time drying. In addition, during the drying process, the lithium fluoride is prone to sticking to each other because of the moist surface, which affects the drying effect and processing efficiency.

[0004] Therefore, in view of the fact that the above-mentioned lithium fluoride slurry washing and drying equipment lacks the function of cyclic loading and crushing, a lithium fluoride slurry washing and drying equipment can be designed. The lithium fluoride slurry is crushed by setting two crushing rollers. After being crushed by the two crushing rollers, the lithium fluoride slurry falls downward to the lower guide inclined plate, slides through the lower guide inclined plate to the inside of the material box, and the lithium fluoride slurry in the material box is transported upward by the rotating feeding spiral sheet, and then falls to the upper guide inclined plate through the discharge chute, slides through the upper guide inclined plate to the middle of the two crushing rollers and is crushed again. In this way, repeated crushing is performed, and the lithium fluoride slurry stuck together is broken up during the crushing and conveying process to ensure the drying effect, thereby realizing the function of cyclic loading and crushing.
