A sealing box 216 is fixedly installed on the bottom separation plate 211, and the driving motor 214 is fixedly installed inside the sealing box 216.

[0046] In this embodiment, the sealing assembly 22 comprises a square frame 221, which is fixedly mounted on the top of the separator 2, a through groove 222 is arranged on the square frame 221, a square groove 223 is fixedly mounted inside the square frame 221, a sealing block 2231 is arranged inside the square groove 223, and one side of the sealing block 2231 extends into the through groove 222; a cylinder 2232 is fixedly mounted inside the sealing block 2231, an electric push rod 2233 corresponding to the cylinder 2232 is fixedly mounted inside the square groove 223, and one end of the electric push rod 2233 is fixedly connected to the inner wall of the cylinder 2232. The electric push rod 2233 is electrically connected to the controller 11, and the controller 11 controls the operation of the electric push rod 2233.

[0047] In this embodiment, the sealing component 22 adjusts the sealing state of the top of the separator 2, so that when the solution entering the extraction tank 1 enters the separator 2, the electric push rod 2233 will work to pull the cylinder 2232 to move, and the movement of the cylinder 2232 will drive the sealing block 2231 to move, and then the position of the sealing block 2231 is adjusted. After the sealing block 2231 moves into the square groove 223, the through groove 222 is no longer sealed, and the solution inside the extraction tank 1 will flow into the separator 2 through the through groove 222.

[0048] Furthermore, in this embodiment, a discharge pipe 23 is fixedly connected to the bottom of the separator 2, and one end of the discharge pipe 23 extends out of the interior of the extraction tank 1. The extraction tank 1 is provided with a cleaning tank 12, and a sealing plate 121 is connected to the interior of the cleaning tank 12 through a hinge, and the sealing plate 121 seals the cleaning tank 12. A base frame 13 is also fixedly installed at the bottom of the extraction tank 1, and a liquid inlet pipe 14 is also provided on the extraction tank 1.

[0049] In the apparatus for extracting lithium chloride from oilfield brine with a multi-stage separation effect provided in this embodiment, a liquid inlet pipe 14 is provided on the extraction tank. When lithium chloride is extracted from brine, the brine needs to be evaporated and crystallized first to obtain a mixture containing sodium chloride and lithium chloride, and the mixture is dissolved in water. When lithium chloride is extracted using the apparatus for extracting lithium chloride from oilfield brine with a multi-stage separation effect, the mixed solution is added to the interior of the extraction tank 1, and then an appropriate amount of reaction solution is added to separate the impurity precipitate from the lithium chloride. The solution is filtered. When the precipitated impurities and the lithium chloride solution are separated, the sealing component is no longer sealed on the top of the separator 2, so that the mixed solution will flow into the interior of the separator 1. When the solution flows through the separation plate 211, the separation plate 211 will separate the precipitate in the solution. The lithium chloride solution is filtered, and the lithium chloride solution is discharged to the outside through the discharge pipe 23. The solution is then filtered through a multi-stage separation structure, which can fully separate the precipitated impurities from the lithium chloride solution, thereby achieving the purpose of improving the separation purity. When the separated precipitate is removed and collected, the driving motor 214 is operated to drive the rotating rod 213 to rotate inside the limiting ring 212. When the rotating rod 213 rotates, it drives the cleaning plate 215 to rotate, and then the cleaning plate 215 scrapes and collects the impurities filtered on the separation plate 211. The collected impurities are manually removed to the outside through the cleaning tank 12, thereby achieving the purpose of collecting the separated precipitate. The collected lithium chloride solution is evaporated and crystallized to obtain lithium chloride crystals, thereby achieving the purpose of extracting lithium chloride.

[0050] Furthermore, in the extraction tank 1 of the lithium chloride extraction device from oilfield brine with multi-stage separation effect provided by the embodiment of the utility model, a power motor 3 may be fixedly installed inside, and the power motor 3 is electrically connected to the controller 11, and the power motor 3 can be controlled to work by the controller 11.

[0051] Specifically, the output end of the power motor 3 is fixedly connected with a driving rod 31, and the power motor 3 drives the driving rod 31 to rotate synchronously when it is working. A stirring blade 311 is fixedly installed on the driving rod 31, and a through hole 312 is symmetrically arranged on the stirring blade 311. A separation block 313 is fixedly installed inside the through hole 312. After the mixed solution containing sodium chloride and lithium chloride enters the interior of the extraction tank 1, when the reaction solution is added to the mixed solution for mixing reaction, the power motor 3 will drive the driving rod 31 to move when it is working, and the driving rod 31 will drive the stirring blade 311 to rotate when it rotates. When the stirring blade 311 rotates, the solution inside the extraction tank 1 will be stirred, and at the same time, a solution will pass through the interior of the through hole 312. The separation block 313 will disperse the solution flowing through the through hole 312, thereby causing the solution to react quickly, thereby achieving the purpose of improving the mixing reaction, so that the lithium chloride extraction device in oilfield brine with multi-stage separation effect has the function of mixing and filtering, and the integrated setting reduces space and improves practicality.

[0052] In summary, when using the lithium chloride extraction device with multi-stage separation effect provided by the embodiment of the utility model to extract lithium chloride from brine, first, after the mixed solution containing sodium chloride and lithium chloride enters the interior of the extraction tank 1, when the reaction solution is added to the mixed solution for mixing reaction, the power motor 3 will drive the driving rod 31 to move, and when the driving rod 31 rotates, it will drive the stirring blade 311 to rotate. When the stirring blade 311 rotates, it will stir the solution inside the extraction tank 1. At the same time, a solution will pass through the inside of the through hole 312, and the separation block 313 will disperse the solution flowing through the through hole 312, thereby allowing the solution to quickly mix and react.

[0053] Finally, when the solution is filtered to separate the precipitated impurities and lithium chloride solution, the electric push rod 2233 will pull the cylinder 2232 to move, and the cylinder 2232 will drive the sealing block 2231 to move, and then adjust the position of the sealing block 2231. After the sealing block 2231 moves into the interior of the square groove 223, the through groove 222 is no longer sealed, and the solution in the extraction tank 1 will flow into the interior of the separator 2 through the through groove 222. When the solution flows through the separation plate 211, the separation plate 211 will filter the precipitate in the solution, and the lithium chloride solution will be discharged to the outside through the discharge pipe 23, and then through multiple The structure of the stage separation is used to filter the solution, which can fully separate the precipitated impurities from the lithium chloride solution, thereby achieving the purpose of improving the separation purity. When the separated precipitate is removed and collected, the driving motor 214 is operated to drive the rotating rod 213 to rotate inside the limiting ring 212. When the rotating rod 213 rotates, it drives the cleaning plate 215 to rotate, and then the cleaning plate 215 scrapes and collects the impurities filtered on the separation plate 211. The collected impurities are manually removed to the outside through the cleaning tank 12, thereby achieving the purpose of collecting the separated precipitate. The collected lithium chloride solution is evaporated and crystallized to obtain lithium chloride crystals.
