Abstract

This utility model relates to the technical field of coal processing and mineral processing equipment, and discloses a high-efficiency and energy-saving coal flotation machine device, including a flotation tank. An installation plate is fixedly connected to the upper surface of the flotation tank. An agitator is fixedly installed on the upper surface of the right part of the installation plate, and an agitator motor is fixedly installed on the upper surface of the upper surface of the left part of the installation plate. An agitator belt is movably sleeved on the outer surface of the output shaft of the agitator motor. The end of the agitator belt away from the agitator motor is sleeved on the outer surface of the agitator. This utility model achieves self-cleaning by using the centrifugal force and gravity generated by the rotation of the equipment itself through a combination structure of friction blocks and springs built into the scraper. No additional power source is required. Friction heats up the surface temperature of the scraper, reducing the viscosity of the coal slurry. Combined with airflow purging and mechanical scraping, a triple self-cleaning mechanism is formed, which significantly reduces the frequency of manual cleaning and equipment downtime, and improves the efficiency of coal flotation.
