AI Technical Summary
The bends in the pipe are prone to deposits and blockages. Existing technologies can only delay the deposits by passively increasing the radius of curvature and adding guide vanes. Built-in filters or grids are prone to clogging and become new sources of blockage.
Design an anti-clogging pipe fitting comprising a bend, a mounting box, and a rotatable crushing wheel. The crushing wheel extends into the bend and is positioned along the flow direction. Combined with a flange and rocker arm structure, it can actively clear blockages.
While reducing fluid resistance, it effectively intercepts and breaks up large fibers or soft impurities, actively removes blockages, improves anti-clogging function, and has high space utilization.
