Description

Technical Field

[0001] The utility model relates to the technical field of lithium extraction from salt lakes, in particular to a stirring structure used for lithium extraction from salt lakes. Background Art

[0002] Lithium extraction from salt lakes refers to a method of extracting lithium from lithium-containing salt lakes. Lithium is an important metal element, mainly used in the manufacture of mobile phone batteries, electric vehicle batteries, and energy storage systems. The stirring process during lithium extraction from salt lakes is to improve the extraction effect of lithium and increase the recovery rate. When the lithium in the salt lake brine exists in the form of lithium carbonate, which is not easily soluble, it is difficult to achieve high-yield lithium extraction by natural deposition alone. Therefore, artificial intervention is needed to accelerate the dissolution and deposition of lithium, thereby increasing the recovery rate.

[0003] However, in the current prior art, when traditional stirring blades are used for stirring and mixing, the stirring will drive the sample to flow, so that the solvent and the sample move synchronously and cannot fully contact each other, resulting in fusion efficiency and thus affecting the mixing effect, thereby reducing dissolution and precipitation. Utility Model Content

[0004] The purpose of the utility model is to provide a stirring structure for extracting lithium from salt lakes to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A stirring structure for extracting lithium from a salt lake comprises a stirring box, wherein an auxiliary component for assisting in mixing a sample and a solvent is arranged inside the stirring box, wherein the auxiliary component comprises a driving shaft arranged inside the stirring box, wherein a plurality of collars are arranged on an outer wall of the driving shaft, stirring blades are arranged on both sides of the outer walls of the plurality of collars, wherein a plurality of through grooves are arranged at one end of the stirring blade, and a discharge hole is arranged at the other end, wherein corrugated plates are arranged on both sides of the inner walls of the plurality of through grooves, and a spiral rod is arranged inside the discharge hole.

[0007] As a preferred solution of the utility model, the drive shaft is located in the mixing box and is rotatably connected to the inner wall of the mixing box through a bearing, and the multiple rings are all sleeved on the outside of the drive shaft and are coaxially connected to the drive shaft.

[0008] As a preferred solution of the utility model, the two stirring blades are respectively connected to the two sides of the ring by bolts, and the outer part of the stirring blade is an arc-shaped structure, which matches the curvature of the inner wall of the stirring box.

[0009] As a preferred solution of the utility model, a plurality of the through grooves are arranged at one end of the rotation direction of the stirring blade and are arranged at the front end of the stirring blade, and the plurality of the through grooves are all connected to the discharge hole.

[0010] As a preferred solution of the utility model, the wavy plate is connected to the inner wall of the through groove by bolts. The wavy plate can guide the angle of the mixed liquid of the sample and the solvent when it flows in the through groove, so that it flows in a curved shape, and when the flow angle changes, the sample and the solvent are squeezed to increase the contact area.

[0011] As a preferred solution of the utility model, the spiral rod is located in the discharge hole and is rotatably connected to the inner wall of the discharge hole through a fixed shaft. When the sample and solvent pass through the spiral rod, they are spirally transported. During the process, the sample and solvent are fully frictionally mixed. The discharge hole has a conical structure with a smaller aperture at one end away from the through groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: in response to the problems raised in the background technology, the present application adopts an auxiliary component, which changes the shape of the stirring blade and sets the stirring blade as a hollow structure, so that the sample and the solvent can flow into the stirring blade when the stirring blade rotates and circulate in the stirring blade, and a wave plate and a spiral rod are installed in the hollow cavity of the stirring blade, thereby changing the shape of the sample and the solvent when circulating in the stirring blade, making the sample and the solvent have frictional contact and fully improving the effect and efficiency of mixing the sample and the solvent.
