Description

Technical Field

[0001] This utility model belongs to the field of lithium extraction technology from salt lakes, and specifically relates to a lithium extraction device from salt lakes. Background Technology

[0002] Lithium is an important strategic resource and an indispensable raw material for modern high-tech products. With the widespread application of lithium and lithium salts and the continuous development of high technology, especially the rapid development of the lithium battery industry in recent years, the market demand for lithium has grown rapidly.

[0003] Currently, existing lithium extraction equipment from salt lakes is generally box-shaped or tank-shaped, with large volume and complex internal structure. It has strong continuous operation capability and is very effective for large-scale lithium extraction work in salt lakes. Conversely, it is obviously not suitable for small-scale lithium extraction operations in salt lakes, which will increase operating costs and have an adverse effect on economic operation.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the problem that traditional lithium extraction devices in salt lakes significantly increase operating costs when dealing with small-scale lithium extraction tasks, thus negatively impacting economic operation, and to provide a lithium extraction device for salt lakes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lithium extraction device from a salt lake includes: a base, a conical mixing chamber, and a pair of separating arms. The base has a pair of parallel vertical support plates on both sides. The conical mixing chamber is located between the two vertical support plates, with its tip pointing downwards and its wider end pointing upwards. The tip of the conical mixing chamber has a discharge pipe, and the wider end of the conical mixing chamber has a feed inlet. A sealing plug is inserted into the feed inlet. A stirring mechanism is located within the conical mixing chamber. The pair of separating arms are symmetrically arranged on both sides of the conical mixing chamber. Each separating arm includes an inclined tube and a horizontal tube. The lower end of the inclined tube is connected to and intersects with the wider end of the conical mixing chamber. A liquid separation plate is located at the connection point between the inclined tube and the conical mixing chamber. The upper end of the inclined tube is connected to and intersects with one end of the horizontal tube. The horizontal tube is rotatably mounted on the vertical support plates.

[0008] In the lithium extraction device from the salt lake described above, preferably, the base and the two vertical support plates are U-shaped as a whole.

[0009] Preferably, the conical mixing chamber has a concave central section at its wide end to form a conical space.

[0010] Preferably, the stirring mechanism includes a motor, a stirring shaft, and a stirring paddle, with the motor located within and centered in the conical space.

[0011] Preferably, one end of the stirring shaft is connected to the motor drive, and the other end extends into the conical mixing chamber corresponding to the discharge pipe.

[0012] Preferably, the stirring paddle is obliquely disposed within the conical mixing chamber;

[0013] The lower end of the agitator is connected to the agitator shaft, and the upper end of the agitator extends in the same direction as the conical inclined surface of the conical mixing chamber.

[0014] Preferably, a valve is provided at one end of the discharge pipe near the conical mixing chamber.

[0015] Preferably, a bearing is fitted onto the outside of the horizontal tube;

[0016] The bearing is nested inside the vertical support plate.

[0017] Preferably, the top of the end of the horizontal tube away from the inclined tube is connected to an arc-shaped drainage plate, and the drainage plate extends obliquely upward.

[0018] Preferably, the size of the liquid separation plate is adapted to the opening of the inclined tube.

[0019] Beneficial effects: The overall structure of this utility model is simple and compact, and the overall weight is small, which facilitates manual operation. By manually rotating the conical mixing chamber and the separation arm around the horizontal tube as the axis, the rapid separation of NaCl solution and Li2CO (lithium carbonate) is achieved, thereby achieving the effect of lithium extraction. The operation process is also extremely simple, which is very suitable for small-scale lithium extraction operations in salt lakes. It will not significantly increase the operating cost and ensure that the economy can operate normally and stably. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] This embodiment aims to provide a lithium extraction device from salt lakes, which is mainly suitable for small-scale lithium extraction operations in salt lakes. The operation process is simple and quick, and the lithium extraction efficiency is high.

[0029] Reference Figure 1 and Figure 3 The system includes: a base 1, a conical mixing chamber 3, and a pair of separating arms. A pair of parallel vertical support plates 2 are welded and fixed on both sides of the base 1. The base 1 and the two vertical support plates 2 are U-shaped as a whole. The conical mixing chamber 3 is located between the two vertical support plates 2, that is, in the upper middle part of the base 1. The tip of the conical mixing chamber 3 is facing down and the thick end is facing up. A discharge pipe 4 is welded to the bottom tip of the conical mixing chamber 3. A valve is provided at the end of the discharge pipe 4 near the conical mixing chamber 3 to minimize the amount of material entering the discharge pipe 4 when the valve is closed. A feed inlet is provided on the side of the thick end of the conical mixing chamber 3. A sealing plug 5 is inserted into the feed inlet. A pull ring is fixed on the middle of the outer side of the sealing plug 5. The sealing plug 5 is made of removable elastic rubber.

[0030] Reference Figure 1-3 The conical mixing chamber 3 is equipped with a stirring mechanism, which includes a motor 9, a stirring shaft 10, and a stirring paddle 11. The center of the thick end of the conical mixing chamber 3 is concave to form a conical space. The motor 9 is installed in the conical space and is centered. The upper end of the stirring shaft 10 is connected to the motor 9 for transmission. The lower end of the stirring shaft 10 extends into the conical mixing chamber 3 corresponding to the discharge pipe 4. The stirring paddle 11 is obliquely arranged in the conical mixing chamber 3. The lower end of the stirring paddle 11 is connected to the stirring shaft 10. The upper end of the stirring paddle 11 extends in the same direction as the conical inclined surface of the conical mixing chamber 3 to avoid hindering the rotation of the stirring paddle 11. Multiple stirring paddles 11 can be set to ensure that the lithium liquid and sodium carbonate can react fully.

[0031] Reference Figure 2 and Figure 3 Two separating arms are symmetrically arranged on both sides of the conical mixing chamber 3. The separating arms include an inclined tube 6 and a horizontal tube 7. The lower end of the inclined tube 6 is welded and connected to the thicker side of the conical mixing chamber 3. At the same time, a liquid separation plate 8 is fixed at the joint between the inclined tube 6 and the conical mixing chamber 3. The size of the liquid separation plate 8 is adapted to the opening of the inclined tube 6. The NaCl solution is filtered through the liquid separation plate 8. The upper end of the inclined tube 6 is connected to one end of the horizontal tube 7. The horizontal tube 7 is rotatably mounted on the vertical support plate 2. Specifically, a bearing 12 is fitted on the outside of the horizontal tube 7. The bearing 12 is nested in the center of the top of the vertical support plate 2.

[0032] In this embodiment, an arc-shaped guide plate 13 is welded to the top of the end of the horizontal tube 7 away from the inclined tube 6, and the guide plate 13 extends obliquely upward. The guide plate 13 is used to guide the NaCl solution separated by the liquid separation plate 8 into the corresponding container.

[0033] In use, open the sealing plug 5, and the operator puts the lithium liquid and sodium carbonate into the conical mixing chamber 3 through the feed port. The lithium liquid and sodium carbonate are fully mixed and reacted by the stirring mechanism. During this period, ensure that the valve of the discharge pipe 4 is closed. After waiting for a suitable time, hold the discharge pipe 4 and rotate the conical mixing chamber 3 and the separating arm about 180° around the horizontal pipe 7. The NaCl solution will flow out automatically along the inclined pipe 6. With the continuous stirring of the stirring mechanism, the NaCl solution and Li2CO3 are separated as completely as possible. After that, the conical mixing chamber 3 and the separating arm are reversed along the original trajectory to reset. Open the valve, and Li2CO3 will automatically slide down from the discharge pipe 4 along the conical inclined surface of the conical mixing chamber 3.

[0034] The lithium extraction device provided in this embodiment has a simple and compact overall structure and a small overall weight, which facilitates manual operation. By manually rotating the conical mixing chamber 3 and the separation arm around the horizontal tube 7 as the axis, the NaCl solution and Li2CO (lithium carbonate) are quickly separated to achieve the lithium extraction effect. The operation process is also extremely simple and is very suitable for small-scale lithium extraction operations in salt lakes. It will not significantly increase the operating cost and ensures that the economy can operate normally and stably.

[0035] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
