AI Technical Summary

Technical Problem

In the existing process of filling magnesium oxide, the filling effect is poor due to the moisture of the magnesium oxide, which is prone to clumping and blockage, affecting production reliability and maintenance difficulty.

Method used

A dehumidification device for filling magnesium oxide in fireproof cables was designed, comprising a tank, pipe joints, a drying tank, and a filling nozzle. By setting up a stirring mechanism, with the cooperation of horizontal and vertical stirring components, the magnesium oxide powder is dried by a heater, and an anti-clogging mechanism is used to prevent accumulation, thereby improving filling efficiency.

Benefits of technology

It effectively improves the drying effect of magnesium oxide powder, prevents accumulation, ensures a smooth filling process, and enhances production reliability and maintenance convenience.
