AI Technical Summary
Existing lithium iron phosphate powder acid leaching equipment suffers from material concentration issues, resulting in limited stirring speed and feeding methods, which affect the acid leaching dissolution rate and reaction quality, leading to low processing efficiency.
The system employs a combination structure of multiple sets of stirring blades, fixed plates, scrapers, and stirring rods, combined with an inclined material distribution hood and a material passage trough, to achieve uniform material distribution and stirring without dead corners, thereby increasing the contact area between the material and the acid solution.
It improves the uniformity of materials and the mixing effect, significantly increases the reaction rate and processing efficiency, shortens the acid leaching reaction time, and solves the problem of low efficiency of traditional equipment.
