AI Technical Summary
In existing pipeline filtration structures, filter elements are easily clogged by impurities, leading to a decrease in media flow rate and affecting filtration efficiency.
Design a filtration structure comprising a hemispherical first filter, a drain pipe, and a return pipe. Impurities pass through the first filter and enter the drain pipe, where they remain at the bottom. The medium is then filtered by a second filter and returned to the source, thus preventing clogging of the first filter.
It improves the efficiency of media filtration, avoids filter element clogging, and ensures stable flow of media in the pipeline.
