Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

It can be understood that the mixed solution is injected into the clarifying cylinder 40 and clarified and layered in the clarifying cylinder 40, solid impurities (the solid impurities comprise solid particles which are insoluble in the solution and crystals precipitated from the solution) may exist in the mixed solution in the clarifying cylinder 40, and the solid impurities can slide down along the inner circumferential surface of the conical section 402 to the slag storage tank 403 at the bottom of the conical section 402 under the action of gravity of the solid impurities, so that the solid impurities are cleaned.

As shown in fig. 1, a first discharge port 4011 and a second discharge port 4012 are located on the peripheral wall of the cylindrical section 401. It can be understood that after the mixed solution is placed in the clarifying cylinder 40 for a period of time, the aqueous solution and the organic solution are layered due to different densities of the two-phase solvents and are not soluble with each other, the layered aqueous solution is discharged from the clarifying cylinder 40 through the first discharge port 4011, the layered organic solution is discharged from the clarifying cylinder 40 through the second discharge port 4012, and the discharged aqueous solution and organic solution can continue the next extraction process.

As shown in fig. 1, a central cylinder 70 is provided in the cavity, one end of a first feeding member 20 is communicated with the central cylinder 70, the other end of the first feeding member 20 is communicated with a supply pipe of an aqueous solution for passing the aqueous solution into the central cylinder 70, one end of a second feeding member 80 is communicated with the central cylinder 70, the other end of the second feeding member 80 is communicated with a supply pipe of an organic solution for passing the organic solution into the central cylinder 70, a central cylinder stirring blade 701 is provided in the central cylinder 70 to draw the aqueous solution and the organic solution into the central cylinder and mix the aqueous solution and the organic solution, and the top of the central cylinder 70 has a first opening (not shown) for discharging the mixed solution, and the bottom of the central cylinder 70 has a second opening (not shown) for discharging solid impurities.

The inventor finds that the integrated extraction equipment in the related art comprises a conical section, and when the solid impurities are discharged, the solid impurities are guided to slide down to the slag storage tank by the inclined inner circumferential surface of the conical section under the action of the gravity of the solid impurities. However, solid impurities such as calcium sulfate are easy to harden under static conditions, are difficult to naturally slide and discharge, require manual work to regularly stop production and clean, are high in labor intensity, and affect working efficiency.
