Embodiment Construction

[0020] Attached below figure 1 The present invention is further described, but they are not intended to limit the protection scope of the present invention.

[0021] Such as figure 1 As shown, the intelligent flotation agent quantitative addition system in this embodiment includes a high-level medicine box 1, a solenoid valve 2, a low-level medicine box 3, a liquid level gauge 4, an electric regulating valve 5, a medicine buffer 6, and an intelligent controller 7 .

[0022] The working principle and working process of the intelligent flotation agent quantitative addition system are as follows:

[0023] The finished flotation agent is injected into the high-level medicine box 1, and the intelligent flotation agent quantitative addition system is started. The liquid level gauge 4 first detects the liquid level of the low-level medicine box 3. When it is detected that the liquid level is lower than the low level limit, the intelligent controller 7 sends out an action command, ...

Abstract

The invention provides an intelligent flotation medicine quantitative adding system. The system comprises a high-position medicine box, a solenoid valve, a low-position medicine box, a liquid level meter, an electric adjusting valve, a medicine buffer and an intelligent controller, wherein the high-position medicine box communicates with a pipeline to the low-position medicine box through the solenoid valve, the liquid level meter is arranged in the low-position medicine box for detecting high and low liquid level restrictions of floatation medicine, the bottom of the low-position medicine box communicates with the medicine buffer downstream through the electric adjusting valve and the pipeline, the medicine buffer communicates with a pulp pretreatment and flotation system through the pipeline, and the solenoid valve, the liquid level meter and the electric adjusting valve are connected with the intelligent controller through a wired mode. The intelligent flotation medicine quantitative adding system has the advantages of automatic real-time addition of the medicine in a flotation process, accurate dosage control and smaller medicine amount, at the same time, effectively solves the defects of poor accuracy, lagged reaction and the like of a conventional manual medicine adding mechanism, and guarantees qualified floatation product indexes.

Description

technical field [0001] The invention belongs to the technical field of flotation dosing, and in particular relates to an intelligent flotation dosing quantitative addition system. Background technique [0002] Flotation technology is the most economical and effective separation method of fine coal slime, and it is also an important method for deep separation of coal. With the improvement of coal mining mechanization, the amount of pulverized coal in the raw coal of the coal preparation plant is increasing, and the flotation operation becomes more and more important. Moreover, the flotation operation is also an important link in the slime water treatment system of the coal preparation plant, which plays an important role in realizing the closed-circuit circulation of the slime washing water and environmental protection. [0003] The traditional flotation operation of the coal preparation plant is carried out manually, and the flotation effect mainly depends on the production...
