Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the present invention includes a delivery pipeline 1 for transporting copper electrolyte, the delivery pipeline can be an FRPP pipe, and the FRPP pipe has a long service life, excellent corrosion resistance, high rigidity, heat resistance, heat preservation, energy saving, reliable Excellent connection performance and good construction performance, very suitable for transporting copper electrolyte.

[0014] Because the pipeline is long, the height difference of the pipeline will be caused by the height difference of the terrain during the laying process along the road. Therefore, the pipeline should be sloped on both sides at a certain high point. A breathing tube 4 is installed at the high point, and the breathing tube communicates with the liquid collection tank 6 through a check valve 5 to avoid generating a large negative pressure...

Abstract

The invention discloses a device for long-distance transportation of copper electrolyte. The device comprises a conveying pipeline (1) for conveying the copper electrolyte, wherein the outlet of the conveying pipeline is communicated with a back flushing pipeline (2). The device has the following benefits: a flushing device is mounted at the inlet or outlet of the conveying pipeline; when the environment temperature is low, the conveying pipeline is flushed to prevent copper sulfate in a residual solution in the conveying pipe from crystallization and blocking the pipeline; as a corrugated hose capable of resisting negative pressure is mounted at a proper distance, the temperature deformation of the pipeline caused by the temperature influence is solved, and the influence of vacuum, generated by the altitude difference influence in the conveying pipe, on the hose can be avoided; the installation of the conveying pipeline requires a certain gradient; a breathing pipe is additionally mounted at a high point in the transportation line to avoid the generation of higher negative pressure to keep liquid in the conveying pipeline; an FRPP pipe is selected as the material for the conveying pipeline, and the material has better corrosion resistance, is basically suitable for various dilute acids, and is easy to mount.

Description

technical field [0001] The invention relates to the treatment of copper electrolyte in the process of copper electrolytic refining in hydrometallurgy, which is used for long-distance transportation of electrolytes with various copper ion concentrations and transportation of solutions with similar properties. Background technique [0002] In the process of copper electrolytic refining, due to the enrichment of impurities in the electrolyte, it is necessary to extract a part of the electrolyte from the electrolysis system for de-impurity every day, so as to avoid impurities affecting the quality of electrolytic copper. The copper electrolyte mainly contains high concentrations of copper and sulfate ions, and also contains a small amount of other impurities such as chloride ions. At the same time, the temperature of the liquid is about 60°C. When the concentration of copper ions is high, this liquid will Easily crystallizes in pipes and is highly corrosive. Most of the existin...
