Closed-loop solution for eddy current storm at cylindrical battery shell opening
Industry pain points:
l Micrometer-level metal dust residue generated at the cylindrical battery shell opening causes the battery to short circuit, posing a risk of thermal runaway.
l Traditional purging has cleaning dead spots,In addition, high-speed airflow will blow dust into the inside of the battery core, causing secondary pollution
l Industry yield loss exceeds1.5%, single-line annual economic losses exceed 10 million
Technical principle:
n Based on computational fluid dynamics design, build100m/s high-speed eddy current field:
n An annular air curtain is generated through the Venturi effect to accurately peel off micron metal dust at the shell opening
n The Coanda effect is used to realize the airflow rotating close to the wall, forming a closed-loop flow field (gas recovery rate100%)
n Integrated multi-stage negative pressure system to achieve efficient separation and collection of dust and airflow
Core technical advantages:
③ Vortex field closed-loop technology: Gas circulation does not spill out, eliminating secondary pollution
③ 100m/s high-speed air flow: Effectively remove adhering dust (removal rate>99.5%)
③ Non-contact processing: Avoid damage to the shell surface and electrolytes
Applicationvalue:
has been widely used in18650/4680/21700 cylindrical battery production line,Effective dust removal rate is higher than90%, helping high-end battery manufacturing break through the bottleneck of dust control.
Shocking technical data
Cleaning efficiency 99.5%
Air flow speed 100m/s (10 times industry standard)
Yield increased by 1.8%(industry leaderMeasured data)
Energy consumption is reduced by 40%(compared to traditional solutions)
