Description

Technical Field

[0001] The utility model relates to the technical field of flotation machines, in particular to a froth scraper of a flotation machine used in mining. Background Art

[0002] The mining flotation machine introduces air into the flotation tank to form bubbles. Mineral particles combine with bubbles to form foam. At this time, the froth scraper is used to scrape the foam floating on the liquid surface from the flotation tank. These foams contain mineral particles separated during the mineral processing process. The principle of the froth scraper is to use the bubbles generated during the flotation process to form a foam layer. The froth scraper scrapes the foam from the liquid surface and transports it to the collection tank by rotating or moving, and finally separates the mineral particles from the slurry.

[0003] According to announcement number CN219723243U, a froth scraper of a flotation machine for mining includes a flotation cell, a rotating shaft is provided on both sides of the upper end of the flotation cell through bearings, and a motor is provided on the rotating shaft, a plurality of groups of mounting rods are evenly provided on the rotating shaft, and a scraper is provided on each group of mounting rods along the length direction of the rotating shaft, a fixed seat is provided on the back of the scraper, a clamping seat is hingedly provided on one side of the fixed seat in cooperation with the mounting rod, and a bolt column is hingedly provided on the other side, a locking groove is provided at the free end of the clamping seat in cooperation with the bolt column, the tail end of the bolt column is stuck in the locking groove, and a locking nut is threadedly provided, two groups of blowing boxes are symmetrically provided in the middle of the flotation cell, a blowing cavity is provided in the blowing box, a blowing hole is provided in the blowing cavity toward the corresponding rotating shaft direction, and a blowing device is provided on the outer side of the flotation cell connected to the blowing cavity. The utility model is convenient for the replacement of the scraper, and has a good effect on scraping the foam in the flotation cell;

[0004] The above patent mentions that the motor is started, and the motor drives the rotating shaft and the mounting rod to drive the scraper to rotate, so that the scraper scrapes the foam above the flotation tank outward to achieve the purpose of separating the minerals. When the scraper scrapes the foam layer from the liquid surface of the flotation tank, the scraper will contact the foam, and the foam will adhere to the scraper. When the scraper scrapes the foam out of the foam discharge port, part of the foam will remain on the scraper, which can easily cause the foam to flow back and reduce the purity of the foam, thereby affecting the recovery rate of the mineral. Therefore, we propose a froth scraper for a flotation machine for mining. Utility Model Content
