AI Technical Summary

Technical Problem

In existing technologies, the circulation and driving effect of the sizing agent in the basalt fiber impregnation tank is not obvious, and the residue is difficult to clean effectively, affecting the impregnation effect and the life of the sizing agent.

Method used

A sedimentation pipe and a circulating impeller were designed. The rotation of the circulating impeller promotes the flow of the wetting agent, which is powered by a circulating pump. The bottom of the sedimentation pipe collects the residue, and a waterless zone and a slag-blocking net are set at the return water pipe to improve the circulation efficiency.

Benefits of technology

It significantly improves the circulation effect of the wetting agent and the efficiency of residue collection and cleaning, thus extending the service life of the wetting agent.
