AI Technical Summary

Technical Problem

In the high temperature state of the existing copper puller nitrogen protection device, the local temperature of the coolant is too high to affect the occurrence of steam, resulting in the copper wire not being effectively protected.

Method used

A copper large-tipper nitrogen protection device is designed, including a steam chamber, a cooling chamber and a nitrogen generator. By installing a spoiler structure and a driving motor outside the mixing tube, the flow of coolant is promoted, the temperature is balanced, and the evaporation efficiency of steam is improved.

Benefits of technology

It effectively reduces the problem of unbalanced coolant temperature, improves the evaporation efficiency of steam, improves the protection effect of copper wire, and extends the storage life of copper wire.

Abstract

The utility model provides a copper heavy drawing mill nitrogen protection device which comprises a steam chamber, a cooling chamber arranged below the steam chamber and a nitrogen generator arranged on one side of the steam chamber, an input sleeve and an output sleeve are arranged at the two ends of the steam chamber respectively, an annealing wheel is arranged on one side of the input sleeve, a copper wire is erected on the annealing wheel, and the nitrogen generator is arranged on one side of the output sleeve. And the copper wire is arranged in the steam chamber through the input sleeve and is finally output into the cooling chamber through the output sleeve. According to the cooling box, through cooperation of the flow disturbing structure and the flow mixing pipe, when a high-temperature copper wire passes through the flow mixing pipe and makes contact with cooling liquid, the driving motor is started to enable the flow disturbing plate to rotate so as to promote flowing of the cooling liquid in the cooling box, and cooling in the flow mixing pipe tends to be balanced.
