Description

Technical Field

[0001] This utility model relates to the field of extraction box technology, specifically a reflux device that can quickly adjust the pH of an extraction box. Background Technology

[0002] Extraction refers to the process of transferring a compound from one solvent to another by utilizing the difference in solubility or partition coefficient between two immiscible (or slightly soluble) solvents. Through repeated extractions, the majority of the compound is extracted. Industrially, extraction processes are generally completed in an extraction chamber. Due to gravity clarification, the solution remains in the clarification chamber for a relatively long time, leading to sediment accumulation at the bottom. If not treated promptly, this will affect the clarification effect. In tungsten and molybdenum smelting, the pH of the solution entering the extraction chamber is extremely unstable due to upstream process technology. In acidic extraction, pH stability is crucial for system startup; large pH fluctuations can cause poor system stability, resulting in poor process parameters.

[0003] The existing extraction tank CN201822067254.1 not only improves extraction efficiency but also avoids the long-term accumulation of sludge adsorbing the organic phase, thus improving the recovery rate of the organic phase. However, it has shortcomings. The existing equipment requires solvent replacement, usually by reducing the flow rate of the aqueous phase, increasing the flow rate of the oil phase, and controlling the pH. This method requires about 20 hours of replacement, which leads to the generation of a large number of unqualified products. Moreover, it cannot adjust the mixing effect and the cleaning effect is not good. Therefore, a reflux device that can quickly adjust the pH of the extraction tank is needed to solve the above problems. Utility Model Content
