[0002] The recycling of the organic phase of the extractant has important economic significance for industrial production. It not only reduces costs but also reduces the pollution of the organic reagent to the environment. The water washing deionization device can elute a certain concentration of ions in the organic phase, and the more washing times, the better the elution effect.

[0003] During the water washing and recycling process of the used organic extractant, the ion content needs to be tested with a conductivity meter. If the organic phase contacts the test probe of the conductivity meter, it will adhere to the probe, reducing the accuracy of the test results. Summary of the Invention

[0006] Preferably, the stirring device includes a stirring kettle, which is fixedly connected to a support frame, a fixing frame is fixedly connected to the top of the stirring kettle, a driving motor is fixedly connected to the center position of the top of the fixing frame, and a stirring rod is fixedly connected to the output end of the driving motor.

[0007] Preferably, one end of a liquid outlet pipe is fixedly connected to the center of the bottom of the stirring tank, and the liquid outlet pipe and the stirring tank are interconnected.

[0008] Preferably, the conductivity meter is threadedly connected to the connecting pipe.

[0009] Preferably, a guide port is provided at the center of the top of the float guide ball, and the guide port and the top end of the telescopic conduit are interconnected.

[0010] Preferably, the bottom end of the second water outlet pipe passes through and extends to the bottom of the outer wall of the washing tank, and the second water outlet pipe is fixedly connected to the washing tank.

[0011] Preferably, the connecting column and the second water outlet pipe are interconnected, and the connecting column and the telescopic guide tube are interconnected.

[0012] Preferably, the other end of the liquid outlet pipe passes through and is fixedly connected to the washing tank, the liquid outlet pipe passes through and extends to the inner wall of the washing tank, and the liquid outlet pipe and the washing tank are interconnected.

[0013] Preferably, a limiting ring is provided on the outer diameter of the stirring rod, and limiting columns are fixedly connected to both sides of the outer diameter of the limiting ring, and the limiting columns are fixedly connected to the inner wall of the stirring tank.

[0014] Working principle: Add the used extractant into the stirring tank of the stirring device to make it as the organic phase, and at the same time add a certain proportion of water into the stirring tank as the aqueous phase, and start the driving motor to drive the stirring rod to rotate and stir, so that the organic phase and the aqueous phase components in the stirring tank are fully mixed, and the ions in the organic phase enter the water. After stirring for a certain period of time, the driving motor in the stirring device stops working, the stirring rod stops rotating, and the mixture of the organic phase and the aqueous phase components flows into the washing tank through the liquid outlet pipe. The mixture in the washing tank is statically separated and stratified. The density of the organic phase is smaller than that of water, so it is in the upper layer, and the density of water is greater than that of the organic phase, so it is in the lower layer. At this time, some ions of the extractant enter the aqueous phase, and the first outlet pipe is led out at the bottom of the washing tank. The middle section of the first outlet pipe is also connected to a connecting pipe, and a conductivity meter is also set in the connecting pipe. In this way, the conductivity meter will always be in the aqueous phase to avoid the conductivity meter probe from contacting the oil phase and causing inaccurate measurement results. The other side of the aqueous phase valve on the first outlet pipe can be connected to a conventional CD I device carries out the adsorption and desorption process of ions in the aqueous phase. After the desorption is completed, the aqueous phase can be returned to the washing tank for recycling until all the ions in the extractant are transferred to the aqueous phase, completing the washing and regeneration of the extractant. After the extraction agent is cleaned, the ions in the organic phase have completely entered the aqueous phase. At this time, the organic phase valve is opened to discharge the organic phase through the diversion port on the top of the float guide ball. The bottom of the float guide ball is connected to the telescopic catheter to meet the continuous changes in the liquid level during the discharge of the organic phase. After the organic phase has completely flowed out, the organic phase to be washed is added again and the above steps are continued. The float guide ball has a density between the density of the aqueous phase and the organic phase and can be suspended at the interface between the aqueous phase and the organic phase. A diversion port is set on the side close to the organic phase, that is, the upper part of the float guide. When the organic phase valve is opened, the organic phase flows out through the diversion port, and it is always ensured that the discharged liquid is the organic phase.

[0015] The present invention provides a device for improving the separation efficiency and test accuracy of capacitive deionization technology. It has the following beneficial effects:

[0016] The present invention mixes an organic phase with an aqueous phase, stirs the mixture for a certain period of time, and then allows the mixture to stand for stratification. At this time, some ions of the extractant enter the aqueous phase, and then a first water outlet pipe is drawn out from the bottom of the washing tank. The conductivity meter is arranged in a connecting pipe on the first water outlet pipe, and the conductivity meter and the connecting pipe are in a vertical state. In this way, the conductivity meter will always be in the aqueous phase, thereby preventing the probe of the conductivity meter from contacting the oil phase, which may cause inaccurate measurement results.
