Description

Technical Field

[0001] The utility model belongs to the field of chemical production, in particular to a flushing water device for closing a flotation tank body. Background Art

[0002] Flotation is a mineral separation method that uses the differences in physical and chemical properties of mineral surfaces to separate minerals. The most widely used method in industry is foam flotation, which is characterized by the fact that useful minerals selectively attach to air bubbles in the pulp and then float to the surface of the pulp, thereby separating useful minerals from gangue. The foam attached to the useful minerals is scraped into the foam tank by the scraper, and then enters the subsequent operation (that is, another flotation tank) through the pipeline, and then the liquid level in the flotation tank is stabilized by other operations such as adjusting the gate.

[0003] In the process of industrial flotation, the foam attached to useful minerals is usually taken out of the flotation tank by a scraper. As the minerals and foam float out, the liquid level of the pulp in the flotation tank will drop. When the liquid level is too low, it will affect the scraping efficiency. At the same time, when the foam attached to the minerals enters the foam tank, the foams have strong adhesion to each other and poor fluidity, which will cause the minerals in the foam tank and pipeline to flow poorly. Therefore, in the process of industrial flotation, a certain amount of additional water needs to be added to keep the pulp level in a constant range, and at the same time, the foam is broken up to facilitate the circulation of the medium mineral products.

[0004] In the existing flotation production process, a certain amount of additional water is usually added to the foam tank to break up the foam in the foam tank. However, the pressure of the additional water is low, and the foam in the foam tank cannot be fully broken up, which affects the circulation of the foam product.

[0005] Therefore, based on the above problems, the utility model provides a flushing water device for a closed flotation cell body which is conducive to increasing the water pressure of the flushing water. Summary of the invention
