The two ends of the slag scraping shafts pass through the side plates and are mounted on the gas collection hood through bearing seats. The motor is mounted on the gas collection hood, and a scraper is provided on the chain between the sprockets of the slag scraping shafts driven by the motor. Although the bearings are placed outside the gas collection hood shell in this technical solution for easy assembly, the slag scraping system component in this technical solution can only be used for one flotation tank, thus causing the limitation of this technical solution.
