Description

Technical Field

[0001] The utility model provides a tool for cleaning ore accumulation in an annular foam trough of a flotation machine, and relates to the technical field of ore accumulation cleaning. Background Art

[0002] With the increasing scale of mineral processing plants and increasing market competition, large-scale, efficient, energy-saving, and automated flotation equipment has been widely promoted and applied. Large and ultra-large aerated mechanical agitation flotation equipment is also used in many mines. The structure of a flotation machine mainly consists of key components such as the cell body, foam tank, impeller, and stator. The foam tank is a circular design and welded to the outer edge of the flotation cell body. Mineralized bubbles rise to the surface of the cell, forming metal foam. The foam flows into the foam tank and then flows through the flow holes in the inter-cell wall to the lower trough for further separation. During this process of metal foam flowing in the foam tank, a small amount of metal is retained in the trough. Over time, the metal will solidify in the trough, reducing the cross-sectional area for the metal foam to pass through, causing it to overflow and lose. During production, the annular foam tank must be regularly cleaned of accumulated ore. Due to the large diameter of the flotation cell body, a steel grating is installed on the upper part of the flotation cell to facilitate personnel access and operation. This makes cleaning the foam tank more difficult. Utility Model Content
