Description

Technical Field

[0001] The utility model relates to the technical field of flotation pulp, in particular to a pretreatment device for flotation pulp. Background Art

[0002] Flotation refers to the use of a surfactant - foaming agent that can generate a large number of bubbles. When air is introduced into water or air enters the water due to the agitation of water, the hydrophobic end of the surfactant is oriented towards the air side of the bubble at the gas - liquid interface, and the hydrophilic end remains in the solution, forming bubbles; another surfactant that plays a role in capturing (generally a cationic surfactant, including fatty amines) adsorbs on the surface of solid ore powder.

[0003] When the existing flotation pulp pretreatment device is in use, in order to make the pulp produce sufficient foam, a foaming device is usually required. The foaming device will occupy a relatively large position inside the treatment device, and it will also affect the moving space of the stirring device, which will affect the stirring efficiency and bring certain adverse effects to the pulp pretreatment process. In order to solve the deficiencies of the existing technology, we propose a pretreatment device for flotation pulp. Summary of the Utility Model
