AI Technical Summary

Technical Problem

In the current chemical liquid dispensing process, dust and insects can easily enter the outlet pipe, causing pollution and blockage, affecting operational efficiency, and the decentralized dispensing mode makes chemical plant management inconvenient.

Method used

A pipe dustproof device based on water film self-sealing is adopted. The residual liquid film on the inner wall of the cylindrical flexible bag adheres to each other due to surface tension, forming a flow channel seal, realizing automatic opening and closing, adapting to different pipe diameters, and reducing the entry of external dust and dirt.

Benefits of technology

It effectively prevents dust and insect pollution, reduces blockages, improves operational efficiency, simplifies management, adapts to different pipe diameters, has low cost, requires no external power, has a simple structure, and provides good dust prevention.
