And so on until electrodes No. 23 and No. 24 electrode 210 excite the measurement process to end.
Since the voltage between the adjacent two electrodes 210 of the slurry layer, the voltage between the adjacent two electrodes 210 of the foam layer, and the voltage between the adjacent two electrodes 210 of the air layer are different, the positions of the interface between the slurry layer and the foam layer and the interface between the foam layer and the air layer relative to the electrode probe mechanism 200 can be known according to the changes of the voltages measured sequentially.
Based on the principle, a voltage change curve is established by using the acquired 23 voltage measurement values, and the liquid level height and the foam layer thickness can be calculated by processing the voltage change curve, so that the influence of factors such as human errors, pulp viscosity, foam layer and the like is avoided. Meanwhile, the cleaning mechanism 300 can clean the surface of the electrode 210, so as to avoid the influence of factors such as ore formation, calcium formation and the like in the detection process. Therefore, the detection precision of the flotation liquid level detection device is higher.
In a word, the flotation liquid level detection device adopts the electrode 210 to measure the flotation liquid level and the thickness of the foam layer, the insulating rings 250 and the electrode 210 are arranged at intervals in a staggered manner, and the liquid level height and the thickness of the foam layer are calculated through the feedback electric signals, so that the influence of foam accumulation, siphon effect and the like on the measurement result is eliminated, and the measurement stability is improved.
In addition, the cleaning mechanism 300 can automatically clean the electrode probe mechanism 200 at regular time, reduces the influence of ore and calcium formation on the measurement result, improves the measurement precision, and reduces the workload and the cost of manual maintenance.
The embodiment also provides a flotation machine, which comprises the flotation liquid level detection device.
