Description

Technical Field

[0001] The present application relates to the technical field of mineral processing equipment, and in particular to a foam slag defoaming device for a mineral processing thickener. Background Art

[0002] A thickener is a device that relies on gravity to separate solids and liquids. In actual mineral processing production, after the slurry enters the thickener, a foam layer will be formed on the surface of the thickener overflow layer. The foam layer contains metal ores and reagents. Overflow from the thickener will cause the loss of metal ores and reagents, increasing the cost of mineral processing. Therefore, the thickener foam layer needs to be defoamed. The commonly used method for defoaming the thickener foam layer is to use high-pressure water to spray the foam surface to break the foam. In practical applications, there are two types of high-pressure water nozzles. One is a direct-injection nozzle, which does not require high water quality, but has a small spray range and general effect; the other is a line-injection or surface-injection nozzle with a small water outlet. To prevent nozzle clogging, it is generally clean water. The water quality requirements are high and the amount of clean water is large. Therefore, the defoaming method using a high-pressure water nozzle has a poor defoaming effect and a large amount of clean water. Utility Model Content
