Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing, in particular to a froth scraping device for a flotation machine. Background Art

[0002] Flotation is a mineral processing process that floats solid minerals from a water suspension based on the differences in the physical and chemical properties of the mineral surface. Among them, the most widely used is the froth flotation method, which is characterized by the fact that useful minerals selectively attach to the air bubbles in the slurry and then float to the surface of the slurry to separate the useful minerals from the gangue. In the prior art, a flotation machine is generally used to float ores. Existing flotation equipment usually generates bubbles by injecting air into the slurry and stirring the slurry. The bubbles then drive the target particles to float, and finally the froth is scraped into the trough by a scraping device to remove the useful minerals.

[0003] The scraping plate of the existing flotation machine scraping device is fixedly installed on the mounting spokes by bolts. A waist-shaped groove is provided on the scraping plate or on the mounting spokes for adjusting the mounting height of the scraping plate. The existing installation method of the scraping plate has the problem of troublesome installation and adjustment, and there is also the problem of inconsistent left and right heights of the scraping plate, which affects the scraping effect; in addition, the existing scraping plate will carry out the floating foam during the scraping process and flow back to the other end of the scraping plate, and drip on the rotating shaft, resulting in a large amount of floating foam remaining on the entire scraping device, which will not only cause corrosion to the scraping device, but also affect the mineral yield, and it is necessary to regularly clean the floating foam on the scraping device.

[0004] Based on this, the present application provides a flotation machine scraper device which is convenient and quick to install and adjust and can effectively prevent the froth from flowing back and dripping onto the rotating shaft. Utility Model Content
