AI Technical Summary
Existing self-cleaning anti-clogging filter devices used in high-temperature metallurgical operations require machine shutdown and replacement due to scraper wear under high-temperature conditions. Wastewater and impurities easily accumulate on the surface of the sealing plate, which is difficult to clean, leading to production disruptions and safety hazards.
A self-cleaning anti-clogging filter device for high-temperature metallurgical applications was designed. The device uses a motor-driven shaft to rotate the scraper and guide plate, thereby achieving self-cleaning of the filter screen and sealing plate. After the scraper wears out, it can be flipped over online for alternating use, thus preventing the formation of hard scale.
It extends the service life of the scraper, ensures production continuity and stability, prevents clogging, and reduces the frequency of disassembly and cleaning difficulty in high-temperature environments.
