[0002] In the process of slag treatment, fine mineral particles float in the water of the high weir single spiral classifier and overflow, and flow into the raw material roller cage sorting screen through the water trough. The high weir single spiral classifier tilts and rotates to dehydrate the fine mineral particles floating in the water, and the sewage flows from the bottom outlet through the water trough into the above-ground sedimentation tank for concentration and precipitation. The above-ground sedimentation tank is often equipped with a scraper, and the sludge accumulated on the bottom of the tank can be scraped off by rotating the scraper plate on the scraper.

[0003] At present, when the scraper mechanism of the scraper is in use, since the bottom of the above-ground sedimentation tank is mostly conical to facilitate the accumulation of sludge, the scraper blade often needs to be set at an angle. The scraper blade is usually directly welded to the stirring shaft and its angle is fixed. For conical tank bottoms with different inclination angles, the scraper blade has poor applicability and is difficult to accurately fit on the side wall, which greatly affects the scraping effect.
