AI Technical Summary

Technical Problem

In existing technologies, anhydrous ether may volatilize when applied to the tableting roller, leading to long-term exposure to low concentrations of ether and causing damage to the nervous system.

Method used

A sodium-ion battery electrode pressing device was designed, which adopts a purification system consisting of a negative pressure fan and an activated carbon plate. The negative pressure fan draws the volatile anhydrous ether into the purification chamber, where it is purified after contact with the activated carbon plate. The purified gas is then discharged. Combined with a detachable dustproof net and a magnetic adsorption structure, the replacement and cleaning efficiency is improved.

Benefits of technology

It effectively purifies volatile anhydrous ether, protects the health of operators, and improves the efficiency and safety of the equipment.
