AI Technical Summary

Technical Problem

In the cobalt-nickel extraction process, failure to clean the calcium slag in a certain stage clarification chamber in a timely manner will affect production or even cause shutdown. Existing technology requires the entire production line to be shut down for cleaning, resulting in low production efficiency.

Method used

A multi-functional segmented extraction device is adopted, with each segment including a redundant segment and a multi-stage interconnected extraction tank. Spare pipelines for the aqueous phase and organic phase are set up. The redundant segment isolates the extraction tank that needs to be cleaned without shutting down the system, thereby achieving the cleaning of calcium slag.

Benefits of technology

This technology enables the cleaning of calcium slag in the extraction tank without shutting down the machine, ensuring continuous and efficient production.
