Hydroclone overflow ore feeding pipeline

Abstract

The invention relates to a hydroclone overflow ore feeding pipeline which comprises a U-shaped pipe, an electromagnetic flowmeter, a blowdown valve and an exhaust valve, wherein a discharge port and a feed port are formed in the left and right sides of the upper end of the U-shaped pipe respectively; the electromagnetic flowmeter is mounted below the discharge port; the blowdown valve is mounted at the bottom of the U-shaped pipe; the exhaust valve is mounted above the feed port; the U-shaped pipe is connected with a measured ore pulp pipeline; the hydroclone overflow ore pulp flows into the U-shaped pipe through the measured ore pulp pipeline via the feed port; the electromagnetic flowmeter measures the ore pulp flow; and the ore pulp is subjected to flotation operation through the discharge port. The hydroclone overflow ore feeding pipeline provided by the invention has the advantages of simple structure, easiness in operation, accurate flow measurement and strong practicability, and can realize stable hydroclone overflow ore feeding while providing a stable working environment for the electromagnetic flowmeter.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a cyclone overflow ore feeding pipeline, which is suitable for cyclone overflow ore feeding. Background technique [0002] The flow rate of the mineral processing plant includes the flow rate of granular materials, pulp and water. The flow rate of the mineral processing plant is one of the important operating parameters that need to be controlled in the process of mineral processing. It is of great significance to improve labor productivity, ensure product quality and rationally utilize energy. [0003] At present, in large-scale non-ferrous metal mines, with the development of large-scale mining equipment, the application of large-scale semi-autogenous mills, ball mills and cyclone units has continuously improved the mine's daily processing capacity. In actual production, the overflow slurry of the cyclone is directly fed into the flotation system through ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned process has the following problems in the application: firstly, the flow rate of the cyclone overflow pulp is large and unstable, and the fluctuation of the flow rate of the pulp is large, resulting in large fluctuations in the follow-up flotation operation, which affects the flotation index; secondly, the cyclone The flow rate of the overflow ore pulp fluctuates greatly, a large amount of air in the feed pipe, and a large number of air bubbles in the pulp cause the flowmeter installed on the pipeline to fail to accurately measure the flow rate of the pulp, resulting in the loss of application value of the flowmeter and the inability to guide production reasonably and accurately
