[0002] When processing kaolin, workers need to use a kaolin flotation machine to screen the kaolin for use. The flotation machine is driven by an electric motor to rotate an impeller, generating centrifugal force to create negative pressure. This draws in sufficient air to mix with the slurry, while simultaneously stirring the slurry and mixing it with reagents. At the same time, it refines the foam, causing minerals to adhere to the foam and float to the surface of the slurry, forming mineralized foam. The mineralized foam is then scraped off by a scraper. Chinese utility model patent, authorized publication number "CN113578532A", discloses an adjustable ore flotation device, including a flotation tank, an inlet...

At the bottom inside the reaction box body 1, a fixed cylinder 18 is fixedly connected. The fixed cylinder 18 is in a cylindrical structure.

[0030] The upper end of the connecting frame 22 is in a "square" shape. The inner height of the upper end of the connecting frame 22 is greater than the major axis length of the cam 21.
