Abstract

This utility model relates to the field of liquid separation technology, specifically to a device for separating two immiscible liquids. It addresses the problem of low separation efficiency in current methods where the extractant and extract solution tend to settle and separate incompletely when discharged to near the separation layer, resulting in poor separation efficiency. The device includes a stirring tank fixedly mounted on a support, which mixes the extractant and extract solution. A stirring rod is installed inside the tank, and a baffle plate is fixed to the inner wall of the tank. A steam pipe is wound around the baffle plate. A transparent glass tube is installed between the first and second valves at the bottom of the tank. By observing the interface between the two liquids within the transparent glass tube and simultaneously controlling the opening and closing of the two valves, a more thorough separation of the two immiscible liquids can be ensured, thus avoiding unnecessary waste of the extractant and improving the overall efficiency of immiscible liquid separation.

Description

Technical Field

[0001] This utility model relates to the field of liquid separation technology, specifically to a device for separating two incompatible liquids. Background Technology

[0002] In the production process, an extractant is added to a mixing tank, followed by the solution to be extracted. After a period of stirring and extraction followed by settling, the two liquids are immiscible. The extractant rises while the extract settles, causing the two liquids to separate. Initially, it is very easy to drain the settled extract. However, when the extract is drained close to the separation layer, it becomes very difficult to separate it completely. Either the settled extract is not drained completely, or the upper extractant is drained along with the settled extract. This makes the liquid separation operation very difficult and can easily result in significant waste of the expensive extractant, ultimately leading to poor liquid separation efficiency and economy. Utility Model Content

[0003] This invention provides a device for separating two incompatible liquids to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for separating two incompatible liquids includes a support, a stirring tank fixedly mounted on the support, a stirring rod rotatably mounted inside the stirring tank, a baffle plate fixedly mounted on the inner wall of the stirring tank, a steam pipe wound around the baffle plate, a transparent glass tube connected to the bottom of the stirring tank, a first control valve between the transparent glass tube and the bottom of the stirring tank, and a second control valve on the side of the transparent glass tube away from the stirring tank.

[0006] Furthermore, a motor is connected to the top of the mixing tank, and the mixing rod is connected to the motor.

[0007] This utility model has the following beneficial effects:

[0008] This utility model provides a device for separating two incompatible liquids, including a stirring tank fixedly mounted on a support for mixing an extractant and an extractant solution. A stirring rod is installed inside the stirring tank, and a baffle plate is fixedly mounted on the inner wall of the stirring tank. A steam pipe is wound around the baffle plate. A transparent glass tube is installed between the first and second valves at the bottom of the stirring tank. By observing the interface between the two liquids within the transparent glass tube and simultaneously controlling the instantaneous opening and closing of the two valves, a relatively thorough separation of the two incompatible liquids can be ensured. This avoids unnecessary waste of the extractant, improves the overall efficiency of incompatible liquid separation, and solves the problem that in the separation of two incompatible liquids, when the extractant solution is discharged to near the separation layer of the two liquids in the later stages, the extractant and extractant solution are prone to sinking and incomplete separation, resulting in low liquid separation efficiency.

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1 As shown, a device for separating two incompatible liquids includes a support 5, a stirring tank 6 fixedly mounted on the support 5, a stirring rod 3 rotatably mounted inside the stirring tank 6, a baffle plate 4 fixedly mounted on the inner wall of the stirring tank 6, a steam pipe 2 wound around the baffle plate 4, a transparent glass tube 8 connected to the bottom of the stirring tank 6, a first control valve 7 between the transparent glass tube 8 and the bottom of the stirring tank 6, and a second control valve 9 on the side of the transparent glass tube 8 away from the stirring tank 6.

[0014] The top of the mixing tank 6 is connected to the motor 1, and the stirring rod 3 is connected to the motor 1.

[0015] In practical application, the lithium liquid to be extracted and the extractant are first added to the stirring tank 6. The motor 1 drives the stirring rod 3 to rotate, so that the lithium liquid and the extractant are fully mixed. At the same time, high-temperature steam is introduced into the steam pipe 2 to ensure the heating effect on the mixture. After the extraction reaction in the stirring tank 6 is completed, the settled extract is discharged to the near interface. By observing the interface between the extract and the extractant in the transparent glass tube 8, the first control valve 7 and the second control valve 9 are opened to allow the extractant to be discharged first. The complete discharge of the extractant is observed in real time. After the extractant has been completely discharged, the second control valve 9 is closed. After ensuring that the extractant has completely settled, the second control valve 9 is opened again, thereby completing the effective and complete separation of the extracted lithium liquid and the extractant. This greatly avoids the unnecessary waste of the extractant and improves the overall efficiency of the separation of incompatible liquids. Therefore, this device has good practicality.
