A PLC 2 is fixedly installed on the outer surface of the extraction tank 3. The upper surface of the extraction tank 3 is open, so the arsenic-containing raw solution and extractant are added into the extraction tank 3 through the opening. A discharge valve 7 is fixedly connected at the axial position of the lower surface of the extraction tank 3. A detection tube 9 is fixedly connected to the end of the discharge valve 7. A densitometer 8 is fixedly installed on the outer surface of the detection tube 9. The detection probe of the densitometer 8 is located inside the detection tube 9. An electric three-way valve 10 is fixedly connected to the end of the detection tube 9. Diverter pipes 11 are fixedly connected to both sides of the outer surface of the electric three-way valve 10. The densitometer 8 and the electric three-way valve 10 are both electrically connected to the PLC 2. An observation port 5 is provided on the outer surface of the extraction tank 3. A transparent plate 6 is fixedly installed inside the observation port 5, so as to facilitate observation of whether the raw solution and extractant inside the extraction tank 3 are separated through the transparent plate inside the observation port 5. Four support legs 1 are fixedly connected in a ring array at equal intervals near the edge of the lower surface of the extraction tank 3.

[0025] In use, the extractant and arsenic-containing stock solution are placed together inside the extraction tank 3. The arsenic in the arsenic-containing stock solution is transferred to the extractant, and the extractant and stock solution are separated into layers. The extractant is located at the bottom of the extraction tank 3. After the discharge valve 7 is opened, the extractant passes through the discharge valve 7 and the detection tube 9 and is discharged from one of the diversion tubes 11. The density of the liquid inside the detection tube 9 is monitored in real time by the densitometer 8, and the signal is transmitted to the PLC2. When the liquid density changes, it indicates that the stock solution has entered the detection tube 9. The PLC2 controls the electric three-way valve 10 so that the liquid in the detection tube 9 enters the other diversion tube 11. This can automatically and quickly separate and discharge the separated extractant and stock solution inside the extraction tank 3 without causing the stock solution and extractant to mix, thus improving the purity of arsenic extraction and purification.
