Description

Technical Field

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

[0002] Flotation machine is a commonly used mineral processing equipment used in the flotation process of ore. Flotation is a physical and chemical separation method that separates valuable minerals from ores by utilizing the difference in affinity between minerals and bubbles. The structure of the mineral flotation machine includes a stirring mechanism, a driving mechanism, and a skimming mechanism.

[0003] When the mineral flotation machine is in use, the stirring mechanism and the driving mechanism cooperate to generate bubbles and introduce the bubbles into the ore pulp. The bubbles come into contact with the mineral particles in the ore pulp. Then, under appropriate reagent conditions, the mineral particles adhere to the bubbles and form foam. Then, the foam floats upward to form flotation concentrate. At this time, the skimming mechanism can skim the foam with mineral particles into the collection box.

[0004] At present, some skimming mechanisms can only skim off the foam at the opening on one side of the flotation machine, and some foam containing mineral particles will float upward and adhere to the inner wall of the flotation machine. It is difficult for the skimming mechanism to skim off the foam that is located deep and attached to the flotation machine. Over time, the foam will continue to accumulate on the inner wall of the flotation machine and is prone to agglomeration, which will not only affect the subsequent collection of mineral particles, but also hinder the subsequent floating movement of the foam.
