Flotation cell liquid level height and foam layer thickness measuring method based on impedance measurement

Abstract

The invention provides a flotation cell liquid level height and foam layer thickness measuring method based on impedance measurement, which is used for measuring the height of ore pulp in a flotation cell and the thickness of a foam layer in the flotation process of gold ore, and comprises a 32-electrode impedance sensor and an impedance analyzer. The impedance sensor is made of stainless steel and corrosion-resistant rubber. The two materials are alternately formed according to a fixed width, and can be adjusted according to the precision required by a measured target. 32 layers of electrodes are arranged in total, and each layer of electrode is connected with a wire from the inside and is finally connected to an impedance analyzer. 32 paths of multiplexers are arranged in the impedance analyzer, and the impedance between each electrode and the electrode at the lowest end can be respectively measured and converted into liquid level height and foam layer and thickness information. The sensor is simple in structure, convenient to use and capable of directly measuring the liquid level height and the foam layer thickness in the flotation tank.

Description

Technical field: [0001] The invention relates to the field of liquid level measurement, in particular to the field of liquid level height and foam layer thickness measurement of a gold mine flotation cell. Background technique: [0002] In the process of gold ore production, the pulp after grinding by the ball mill is separated by the separator and then flows into the flotation cell. In the flotation cell, the beneficiation agent is injected to make the beneficiation agent complex with the gold in the pulp; the compressed air is charged at the same time, and the complexed gold is brought to the surface of the pulp to obtain a foam rich in gold ore. The scraper is driven by the motor to scrape out the foam to obtain gold 20 concentrate. In the above flotation process, the slurry level and the thickness of the foam layer are important parameters to be measured. If the liquid level is too high, the scraper will scrape the pulp, resulting in impure products; if the liquid leve...
