Description

Technical Field

[0001] This invention relates to the field of lithium extraction technology from salt lakes / lithium extraction from seawater, specifically to a device and method for preventing compaction in lithium ion sieves. Background Technology

[0002] Lithium is an indispensable raw material supporting the development of the new energy vehicle industry. Seawater contains a large amount of lithium ions, but the concentration is very low, often only around 0.1-0.2 ppm. This requires continuous purification of large quantities of seawater, but due to the low concentration, the yield of lithium extracted from seawater is low. However, many existing seawater desalination plants, thermal power plants, nuclear power plants, and large-scale chemical plants with large-scale seawater desalination capabilities discharge concentrated brine with a higher concentration of lithium ions than ordinary seawater, and this brine also has its own flow rate, making it a very worthwhile source of seawater to utilize.

[0003] Existing seawater desalination plants, thermal power plants, nuclear power plants, and large chemical plants are all located in remote areas, such as high-altitude areas like Tibet and Qinghai. The lithium-ion screens used to adsorb lithium ions need to be transported over long distances. During transportation, the lithium-ion screens may be compacted and stuck together due to bumps, which can damage them. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that lithium ion screens may be compacted and stuck due to bumps during long-distance transportation, which may cause damage to the lithium ion screens. Thus, the present invention provides a device and method for preventing compaction of lithium ion screens.

[0005] To solve the above-mentioned technical problems, the present invention provides a device for preventing compaction of lithium-ion screens, comprising:

[0006] The container is designed to hold lithium-ion sieves.

[0007] A rotating shaft is rotatably mounted inside the barrel, and blades are mounted on the rotating shaft;

[0008] A drive device is installed at the top of the barrel, and the drive end of the drive device is connected to the rotating shaft. The drive device is adapted to drive the rotating shaft to rotate the blades.

[0009] Optionally, the driving device includes a windmill, which is connected to the rotating shaft via a linkage device.

[0010] Optionally, the linkage device is a gear structure.

[0011] Optionally, a storage spring is provided at the connection point between the drive device and the rotating shaft.

[0012] Optionally, the energy storage spring is connected to the drive device via a coupling.

[0013] Optionally, it also includes a stainless steel frame located on the outside of the barrel.

[0014] Optionally, an air hole is provided at the top of the barrel.

[0015] Optionally, the bottom of the barrel is provided with a valve suitable for extracting lithium ion sieves.

[0016] A method for preventing compaction is also provided, including the aforementioned anti-compaction device for lithium-ion screens, and further comprising the following steps:

[0017] During transportation, the lithium-ion screen is driven by a drive unit to rotate the shaft, which in turn drives the paddles to rotate, continuously agitating the lithium-ion screen.

[0018] The technical solution of this invention has the following advantages:

[0019] 1. The lithium-ion sieve anti-compaction device provided by the present invention includes a rotating shaft installed in a barrel for holding the lithium-ion sieve, with blades mounted on the rotating shaft. A drive device is installed at the top of the barrel to drive the rotating shaft to rotate. During the rotation of the rotating shaft, the blades continuously agitate the lithium-ion sieve, thereby protecting the lithium-ion sieve. Through continuous agitation, the lithium-ion sieve is prevented from compacting and sticking during long-distance bumpy transportation.

[0020] 2. The anti-compaction device for lithium-ion screens provided by the present invention uses a windmill as the driving device. During the transportation of lithium-ion screens, the windmill is exposed and rotates due to the wind force as the transport vehicle moves forward, thereby driving the rotating shaft to rotate. This avoids driving the rotating shaft through an electric device, making the design simple, easy to implement, energy-saving, and easy to maintain.

[0021] 3. The anti-compaction device for lithium ion screen provided by the present invention has a storage spring at the connection position between the drive device and the rotating shaft. The storage spring is connected to the drive device through a coupling. When the drive device rotates, it drives the storage spring to store force. When the storage spring is tightened to a preset position, the coupling is loosened, so that the storage spring drives the rotating shaft to rotate and agitate the lithium ion screen.

[0022] 4. The anti-compaction device for lithium ion screens provided by the present invention has a stainless steel frame on the outside of the barrel to protect the barrel during transportation.

[0023] 5. The anti-compaction method provided by the present invention uses a rotating shaft to drive the paddle to continuously agitate the lithium ion screen, thereby achieving the effect of preventing compaction and adhesion of the lithium ion screen. Attached Figure Description

[0032] Example 1

[0033] This embodiment provides a specific implementation method for an anti-compaction device for lithium-ion sieves, such as... Figure 1 As shown, a rotating shaft 5 is installed inside the barrel 2 used to hold the lithium ion screen, and a paddle 6 is installed on the rotating shaft 5. A drive device 1 is installed at the top of the barrel 2 to drive the rotating shaft 5 to rotate. During the rotation of the rotating shaft 5, the paddle 6 continuously agitates the lithium ion screen, thereby protecting the lithium ion screen. Through continuous agitation, the lithium ion screen is prevented from being compacted and stuck during long-distance bumpy transportation.

[0034] Specifically, the shaft 5 is arranged vertically, the blades 6 extend radially, and the blades 6 are arranged in three to four pieces.

[0035] In this embodiment, the driving device 1 is a windmill, which can rotate on its own when exposed to wind. During the transportation of the lithium-ion screen, the windmill is exposed and rotates when exposed to wind, thereby driving the rotating shaft 5 to rotate. This avoids the need for an electric device to drive the rotating shaft 5, making the design simple and easy to implement. Specifically, the windmill is connected to the rotating shaft 5 through a linkage device 3, which is a gear structure. Through the engagement of the gears, the rotation direction of the windmill is converted to the rotation direction of the rotating shaft 5.

[0036] In this embodiment, a storage spring is provided at the connection point between the drive device 1 and the rotating shaft 5. The storage spring is mounted on the rotating shaft 5 and is connected to the drive device 1 via a coupling. When storage is required, the storage spring is connected to the drive device 1 via the coupling. When storage is complete or no storage is needed, the storage spring is disconnected from the drive device 1 via the coupling. When the drive device 1 rotates, it drives the storage spring to store energy. When the storage spring is tightened to a preset position, the coupling is released, causing the storage spring to drive the rotating shaft 5 to rotate and agitate the lithium ion screen.

[0037] In this embodiment, a stainless steel frame 4 is provided on the outside of the barrel 2 to protect the barrel 2 during transportation.

[0038] In this embodiment, the top of the barrel 2 is covered with a screw cap 8, and the rotating shaft 5 passes through the screw cap 8. An air hole is provided on the screw cap 8 to prevent the local gas from being squeezed and opening the screw cap when bumping.

[0039] In this embodiment, a valve 7 is provided at the bottom of the barrel 2, through which lithium ion sieves can be extracted from the barrel 2. The valve 7 is either a one-way valve or a two-way valve.

[0040] In this embodiment, the barrel 2 is made of lightweight, tough, and corrosion-resistant materials such as polyvinyl chloride and polytetrafluoroethylene. It is semi-transparent, and the outer side of the barrel 2 is marked with graduations, allowing for easy determination of the amount of adsorbent inside. The blade 6 is made of materials such as polyvinyl chloride and polytetrafluoroethylene, possessing a certain degree of hardness and toughness, and will not damage the lithium-ion screen.

[0041] Example 2

[0042] This embodiment provides a specific implementation of the anti-compaction method, which is carried out using the anti-compaction device for lithium-ion screens in Embodiment 1. The method includes the following steps: During the transportation of the lithium-ion screen, the drive device 1 drives the rotating shaft 5 to rotate. During the rotation of the rotating shaft 5, the impeller 6 rotates, continuously agitating the lithium-ion screen. By continuously agitating the lithium-ion screen through the rotating shaft 5 and the impeller 6, the effect of preventing compaction and adhesion of the lithium-ion screen is achieved.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
