Description

Technical Field

[0001] The utility model relates to the technical field of liquid level detection, in particular to a liquid level detection device for a mining flotation machine. Background Art

[0002] Flotation cell, short for flotation concentrator, refers to the mechanical equipment that completes the flotation process. In the flotation cell, the mineral solution treated with reagents is stirred and aerated, causing some mineral particles to selectively adhere to the bubbles. These float to the surface of the mineral solution and are removed as a foam product, while the rest remain in the mineral solution, achieving the purpose of mineral separation.

[0003] When most flotation machines are used for mineral processing, it is difficult to see the specific liquid level with the naked eye because a large amount of foam will float on the surface of the ore liquid. In addition, the foam will affect the liquid level detection device, resulting in a discrepancy between the actual liquid level of the detected slurry and the liquid level displayed by the liquid level control system, affecting the flotation process operation and making it difficult for on-site operators to control the liquid level. Therefore, a liquid level detection device for a mining flotation machine is now provided. Utility Model Content

By cooperating with a liquid level detection assembly, a lifting assembly, a protective tube, and a heating assembly arranged on an L-shaped vertical plate, the foam inside the protective tube can be eliminated, so that the float ball is suspended on the ore liquid inside the protective tube. After the indicator ring follows the float ball to hover, the liquid level of the ore liquid can be understood by observing the scale reading indicated by the indicator ring, thereby greatly reducing the impact on the flotation process operation, helping to assist on-site operators in liquid level control, having good practicality, and overcoming the deficiencies of the prior art.
