AI Technical Summary

Technical Problem

In existing technologies, the feeding machine is prone to clogging during the raw material feeding process of hemodialysis membrane spinning, and the PVP after absorbing moisture is difficult to clean, resulting in a high risk of contamination in the next batch.

Method used

A fully automated hemodialysis membrane spinning raw material feeding device was designed, which adopts an anti-clogging mechanism and a micron-level stainless steel filter. The device avoids clogging through a dredging groove and a fan blade structure, and the filter can be easily replaced through a stainless steel suction head and threaded tube design, achieving rapid cleaning.

Benefits of technology

It effectively reduces clogging during the feeding process, improves feeding efficiency, reduces the hassle of cleaning the filter screen, and reduces the risk of contamination in the next batch.
