Tailing slurry treatment device for online visual flotation system detector
Technical Field
The invention belongs to the technical field of mining production equipment, and particularly relates to a tailing slurry treatment device for an online visual flotation system detector.
Background
At present, industrial minerals become increasingly poor, fine and complex, and as comprehensive utilization and environmental protection requirements of metallurgy, chemical engineering and other processes are increasingly improved, flotation scientific technology becomes more important. The flotation is to make use of the hydrophobic and gas-philic (or oleophilic) property of the material itself or obtained after the treatment of the medicament to make the material gather at the water-gas or water-oil interface to achieve enrichment, separation and purification.
The proper dosage in the flotation process is an important means for ensuring the ash content of the flotation clean coal, improving the yield of the clean coal and reducing the consumption of medicaments. The flotation production dosing amount is determined by a conventional method of pre-dosing through detecting the flow and concentration of ore pulp and controlling the dosing amount by manually observing the gray level of tailings. The real-time online detection and feedback of the tailing state in the flotation process are very important to the flotation result quality, and the existing online visual flotation system detector tailing slurry storage tank has the defects that:
(1) the supply flow of the tailing slurry needs to be manually adjusted, so that the use is inconvenient;

(3) the requirement for field installation of the tailing slurry storage tank is high;
(4) the structure of the tailing slurry storage tank is easy to deposit and cannot be cleaned by itself.
