Description

Technical Field

[0001] The present invention relates to the technical field of electroosmotic drainage tests, and in particular to an electroosmotic drainage test device that can control the energization mode and monitor multiple parameters. Background Art

[0002] In the mining industry, tailings are the residues after ore processing and are usually stored in tailing ponds in the form of slurry. The main challenges in tailings treatment are their high water content and potential environmental risks. Traditional drainage methods are less efficient and difficult to meet modern environmental protection and safety requirements.

[0003] The electroosmotic drainage method can drain free water and some bound water in tailings, and the drainage effect is significant and continuous. In recent years, it has become a research hotspot in engineering, and seeking the best electroosmotic conditions has also become the research object of many scholars. Existing research shows that an appropriate energization mode can reduce anode corrosion and energy consumption in electroosmosis. However, the research on the current change mechanism in electroosmotic tests is insufficient. Existing indoor electroosmotic test devices often use the weighing method to measure the drainage volume, which is too cumbersome and cannot measure the water content, pressure, and temperature at different positions in the test box. In addition, the existing test devices cannot automatically control the on-off of the current. The proposed invention can achieve intermittent energization and measure the water content, pressure, and temperature at different positions in the test box in a more accurate way during electroosmotic drainage. Summary of the Invention

[0004] The purpose of the present invention is to provide an electroosmotic drainage test device that can control the energization mode and monitor multiple parameters. Different from other devices that measure the electroosmotic drainage performance by weighing, this device measures by the change in water content, reducing the error in collecting the drainage volume and also being able to monitor the real-time change in water content at different positions. Moreover, two-dimensional electroosmotic drainage optimizes the influence of gravity on electroosmotic performance, and intermittent energization control can obtain the best energization cycle and on-off ratio.
