AI Technical Summary

Technical Problem

In existing electrolytic copper foil production, the mixing device for the surface treatment solution cannot achieve sufficient mixing, which easily causes eddies and dead zones, affecting mixing efficiency and uniformity.

Method used

The system employs a combination of multiple flow guiding components and stirring components. The flow guiding components include an annular flow guiding plate and a spiral flow hole on the inner side wall of the stirring tank, which, together with the stirring plate and the turbulence channel, guide the liquid flow in multiple directions, eliminate dead zones, and increase the frequency of molecular collisions.

Benefits of technology

It significantly improves the mixing efficiency of the treatment fluid, ensures uniform distribution of components, extends equipment lifespan, and reduces maintenance costs.
