Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flow tubes are arranged in serial-connection configuration, then magnetic removal effect is improved, but flowing area is reduced and yield is low
Solution Approach 1:
The magnetic filter is divided into multiple independent magnetic rods arranged in parallel within a single flow tube, rather than using serial connection. Each magnetic rod independently captures magnetic impurities, increasing the total magnetic removal capacity while maintaining large flowing area for high productivity.
2Reliability
If magnetic rods are arranged individually, then magnetic removal effect is improved, but cleaning process becomes complex and time-consuming
Solution Approach 1:
Multiple magnetic rods are merged into a single integrated magnetic roller structure. The cleaning process is unified by using one common scrape ring that cleans all magnetic surfaces simultaneously, reducing operational complexity and time compared to individually cleaning each rod.
Solution Approach 2:
The magnetic roller is designed to rotate, bringing different portions of its surface sequentially into contact with the scrape ring. This dynamic rotation allows continuous cleaning of the entire magnetic surface area without requiring disassembly or complex positioning mechanisms.
3Manufacturing precision
If magnetic rods are cleaned individually, then cleaning thoroughness is improved, but human labor and time are wasted
Solution Approach 1:
The magnetic roller automatically presents its entire surface to the scrape ring through rotation, enabling self-cleaning without manual intervention. The system performs thorough cleaning of all magnetic surfaces simultaneously, eliminating the need for labor-intensive individual rod cleaning while maintaining cleaning quality.
4Ease of operation
If magnetic rods are disassembled for cleaning, then cleaning accessibility is improved, but sealing risks increase
Solution Approach 1:
The integrated magnetic roller design allows the same structure to serve both magnetic adsorption and self-cleaning functions. The scrape ring provides universal cleaning capability for the entire roller surface without requiring disassembly, thereby maintaining sealing integrity while ensuring thorough cleaning accessibility.

AI summary
A magnetic adsorption of the apparatus includes multiple magnetic adsorption barrels each including a barrel body, a magnetic roller arranged in an interior of the barrel body, and a scrape ring. The magnetic roller is reciprocally slidable relative to the scrape ring. The magnetic roller includes a roller body, a permanent magnet, a directing end-wing connected to a free end of the roller body, and a permanent magnet driving and moving mechanism. The roller body is reciprocally slidable relative to the scrape ring. The permanent magnet is arranged in the interior of the roller body. The permanent magnet driving and moving mechanism can drive the permanent magnet to move in a direction approaching or away from the directing end-wing. The slurry magnetic filter apparatus adopts a permanent magnet as a magnetic adsorption system with a relatively large effective magnetic adsorption surface area for better resolving the cleaning issues.
