Example Embodiment

[0021] At present, the liquid level sensor not only has a wide range of varieties, but also has greatly improved detection accuracy, which provides great convenience for slurry level detection. The thickness of the foam can be tested according to the conductivity of the foam layer. The testing equipment has a wide range of options, and the actuator technology has also been rapidly developed. The invention combines the controller 8, the actuator (the dosing amount regulating valve 3 and the gate height adjustment device 6), the liquid level sensor 4, and the electrode foam thickness sensor 1 to intelligently detect the slurry level and foam thickness And adjustment, and achieved satisfactory results.

[0022] The level sensor 4 is a pressure type level gauge, a float level gauge, an electronic ruler level gauge, an ultrasonic level gauge, a laser ranging level gauge, a radar level gauge or a magnetostrictive level gauge, which can be based on actual conditions. Select the situati...

Abstract

The invention discloses a method for adjusting the ore slurry liquid level and foam thickness of a coal flotation machine. The method comprises the steps that a liquid level sensor and a foam thickness sensor which are mounted in a tank body of the flotation machine are utilized to detect the ore slurry liquid level and the foam thickness in real time, a detection result is transmitted to a controller, the controller outputs a control signal of a flashboard height adjusting device according to the detection result of the ore slurry liquid level, correspondingly a flashboard ascends or descends, and the liquid level of the tank body of the flotation machine is adjusted to a set value; according to the detection result of the foam thickness, a control signal of a dosage adjusting valve is output to increase or decrease the dosage, and therefore the foam thickness is adjusted. According to the method, an ore slurry liquid level and foam thickness detection and adjustment system arranged in the flotation machine is utilized to control the internal ore slurry liquid level and foam thickness of the flotation machine in real time, so that the influence of human factors is eliminated, the labor intensity of operators is reduced, the ore slurry liquid level and the foam thickness can be accurately and timely adjusted, and the flotation effect of concentrate is ensured.

Description

technical field [0001] The invention relates to an intelligent detection and adjustment method for the pulp liquid level and foam thickness in a tank of a coal flotation machine, belonging to the technical field of separation. Background technique [0002] Flotation is a method of separating useful minerals from useless minerals under the action of chemicals and according to the differences in mineral surface properties. The flotation concentrate is attached to the foam layer on the surface of the pulp in the flotation machine, and the foam layer and the pulp are separated by overflow or the concentrate foam scraper. Therefore, the control of the flotation pulp level and foam thickness is very critical. If it is too low, the foam layer cannot reach the overflow weir, and the overflow cannot be realized or the concentrate foam can be collected by the scraper, and the concentrate product cannot be obtained during the production process; if the slurry level is too high, a foam ...
