[0002] Most existing seawater uranium extraction systems are installed on offshore platforms, and the adsorbent materials are immersed in seawater. On the one hand, the sea is rough, especially when encountering typhoons, which can easily cause equipment destruction or loss of adsorbent materials. On the other hand, it is easy for organisms to attach to the adsorbent materials and clog them. On the other hand, when the adsorbent materials need to be evaluated, due to the influence of ocean currents, the adsorption effects of the same batch of adsorbent materials at different times are different, which is not conducive to evaluating the adsorption performance of the adsorbent materials. Summary of the invention

[0006] The wind-powered water-lifting device comprises a pump, a wind energy conversion component, and a one-way valve; the first end of the water inlet pipe is used to extend into the seawater, the second end of the water inlet pipe is connected to the pump, and the one-way valve allows seawater to flow unidirectionally from the first end of the water inlet pipe to the second end of the water inlet pipe; the pump is used to extract seawater and transport it to the middle water pipe; the wind energy conversion component is used to convert wind energy into energy for the pump to pump water; the bottom of the water bucket is also connected to the water inlet pipe through a water supply pipe; the connection positions of the one-way valve and the water supply pipe with the water inlet pipe are arranged in sequence along the direction of seawater flow.

[0007] Optionally, a coarse filter and a fine filter are sequentially arranged on each of the middle water pipes along the direction of coastal water flow.

Since the filter device filters the sediment, the adsorption of uranium on the adsorption bed is prevented from being affected by microorganisms.

The system is stable and inexpensive. It provides a new solution for testing uranium adsorption materials and mass production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with specific embodiments, but the protection scope of the present invention is not limited thereto.

[0020] refer to Figure 1 The present invention provides a wind-powered seawater uranium extraction system, comprising: a wind-powered water extraction device, a water bucket 4, one or more middle water pipes (for example, a first middle water pipe 241, a second middle water pipe 242), and one or more adsorption beds 5.

[0021] The wind-powered water-lifting device is used to extract seawater by relying on wind energy and transport the seawater to the water bucket 4 through the middle water pipe.

[0022] Wind-powered water-lifting devices rely on windmills, sails or wind-powered water-lifting machines to extract seawater and convert wind energy into mechanical energy for pumping water.

[0023] The seawater may be extracted using known wind powered water extraction devices.

[0024] Figure 1 In the illustrated embodiment, a windmill is used to provide energy for the pump 32 to pump water.

[0025] The height of the water bucket 4 is relatively high, and at least the bottom or lower part of the water bucket 4 is higher than the top of the adsorption bed 5. The wind-powered water-lifting device converts wind energy into the gravitational potential energy of seawater.

[0026] The two ends of each middle section water pipe are respectively connected to the water outlet of the wind power water lifting device and the water inlet of the water bucket 4. The water inlet of the water bucket 4 is located at the upper part of the water bucket 4. A filtering device is arranged on each middle section water pipe.

[0027] The filtering device is used for seawater purification, and disc filters, filter cloths, sand filters, filter cotton, etc. can be selected. Figure 1 In the embodiment shown, the filter device is divided into a sand filter cylinder and a fine filter device. The former filters a larger diameter, while the latter filters a smaller diameter. The sand filter cylinder is not shown, and only its installation position 26 is shown. The fine filter device is not shown, and only its installation position 28 is shown.

[0028] The sand filter is filled with 2-4mm quartz sand particles, which can filter out particulate impurities larger than 10 microns; the fine filtration equipment is located at the rear end of the sand filter, and is filled with a 5-micron PP wound filter element.

[0029] The upper end of the adsorption bed 5 is connected to the lower part of the water bucket 4, and the lower end of the adsorption bed 5 is used to discharge seawater.

[0030] In order to further prevent biological reproduction and attachment, the outer shells of the water bucket 4, each water pipe, each filter device, and the adsorption bed 5 are all light-shielded, for example, by wrapping the outer shell with a black light-proof material, for example, the water pipe is a black nylon water pipe.

[0031] refer to Figure 1 The wind-powered water-lifting device comprises: a first water inlet pipe 21, a second water inlet pipe 22, a pump 32, a wind energy conversion component, and a one-way valve; the first end of the first water inlet pipe 21 is used to extend into the seawater, the second end of the first water inlet pipe 21 is connected to the first end of the second water inlet pipe 22, the one-way valve is arranged on the first water inlet pipe 21, and the one-way valve allows the seawater to flow unidirectionally from the first end of the first water inlet pipe 21 to the second end of the first water inlet pipe 21; the second end of the second water inlet pipe 22 is connected to the pump 32, and the pump 32 is used to extract seawater and transport the seawater to the middle section of the water pipe; the wind energy conversion component is used to convert wind energy into energy for the pump 32 to pump water; the bottom of the water bucket 4 is also connected to the middle section of the second water inlet pipe 22 through a water supply pipe 43.

[0032] With such a design, even if the seawater falls below the first end of the first water inlet pipe 21, the water in the water bucket 4 can enter the first water inlet pipe 21 and the second water inlet pipe 22 through the water supply pipe 43, thereby avoiding the interruption of the water flow below the pump 32. Since the one-way valve is provided in the first water inlet pipe 21, the water in the water bucket 4 will not flow into the sea. The pump 32 can always pump seawater. The reliability of the system operation is improved.

[0033] In this embodiment, the first water inlet pipe 21 is arranged obliquely on the coast, and the second water inlet pipe 22 is arranged horizontally on the land.

[0034] The first water inlet pipe 21 and the second water inlet pipe 22 can also be replaced by a complete section of flexible water pipe.

[0035] Figure 1 The wind energy conversion component in the illustrated embodiment is a windmill. The windmill includes an impeller 34, a gear box 35, a bracket 31, and a tail wing 36. The impeller 34 captures wind energy, and converts the mechanical energy of the impeller 34 rotation into mechanical energy of the up and down stroke movement of the connecting rod 33 and the up and down reciprocating movement of the movable parts of the pump 32 through the gears and the crankshaft in the gear box 35. The wind energy conversion component can be a commercially available component, and the present invention does not limit its structural details. The pump 32 is specifically a vacuum water pump, which pumps seawater into a high bucket 4. The pump 32 is made of nylon material.

[0036] Optionally, there are multiple adsorption beds 5, and the system also includes a first water outlet pipe 44 and a second water outlet pipe 46, the first end of the first water outlet pipe 44 is connected to the water outlet at the bottom of the bucket 4, and the second end of the first water outlet pipe 44 is closed, the upper ends of the multiple adsorption beds 5 are connected to different positions of the first water outlet pipe 44, and the lower ends of the multiple adsorption beds 5 are connected to different positions of the second water outlet pipe 46 to discharge seawater through the second water outlet pipe 46.

[0037] The seawater in the water bucket 4 flows into the adsorption bed 5 through the first water outlet pipe 44. The seawater in each adsorption bed 5 flows to the second water outlet pipe 46, and then the seawater is discharged from the second water outlet pipe 46.

[0038] Optionally, an overflow port is further provided at the top of the water bucket 4, and the system further comprises an overflow pipe 41, a first end of the overflow pipe 41 is connected to the overflow port, and a second end of the overflow pipe 41 is used for discharging seawater.

[0039] When the water level in the water bucket 4 is too high, the excess seawater can be discharged through the overflow pipe 41. In this embodiment, the second end of the overflow pipe 41 is connected to the first end of the second water outlet pipe 46.

[0040] Optionally, it also includes an explosion relief valve, which is installed at the water outlet of the wind-powered water pumping device, and the middle section of the water pipe receives seawater through the explosion relief valve. The explosion relief valve is not shown. Figure 1 Its installation position 23 is shown in FIG.

[0041] When the water pressure discharged from the wind-powered water-lifting device is too high, the explosion relief valve automatically starts to drain water, thereby ensuring the safe operation of subsequent equipment.

[0042] Optionally, a first solenoid valve 42 is further included, and the first solenoid valve 42 is connected to the bottom of the bucket 4. When the first solenoid valve 42 is controlled to open, the seawater (relatively turbid) at the bottom of the bucket 4 can be discharged. This is conducive to the cleaning of the bucket 4. Specifically, the first solenoid valve 42 is installed on the sewage pipe at the bottom of the bucket 4. The start and close of the first solenoid valve 42 can be controlled manually or remotely by a program. A pressure transmitter is also provided on the sewage pipe, and the liquid level height in the bucket 4 can be judged by the water pressure value.

[0043] Optionally, a second solenoid valve 45 is further included, and the second solenoid valve 45 is used to control the connection between the water bucket 4 and the adsorption bed 5. When the adsorption material in the adsorption bed 5 needs to be replaced, the second solenoid valve 45 is controlled to cut off the first water outlet pipe 44.

[0044] Optionally, a pressure gauge is also included, which is arranged in a one-to-one correspondence with the middle water pipe and is installed at the front section of the middle water pipe. The pressure gauge is used for users to know the water pressure in the middle water pipe in real time. The pressure gauge is not shown, and its installation position 25 is shown in the figure.

[0045] Optionally, a flow meter (not shown) may be provided at the rear end of the second solenoid valve 45 of the wind-powered seawater uranium extraction system. The flow meter is used to count the total flow rate flowing into the adsorption bed 5, or to count the flow rate flowing into a single adsorption bed 5 separately. The flow meter can measure the instantaneous flow rate and the cumulative flow rate. In this way, the adsorption performance tests of the same batch of adsorption materials at different time periods can obtain relatively uniform test results.

[0046] Optionally, the wind-powered seawater uranium extraction system further includes a sedimentation tank 1 for settling impurities in the seawater. Figure 1 In the illustrated embodiment, the sedimentation tank 1 is an inclined plate sedimentation tank.

[0047] An anemometer is also installed on the top of the wind-powered water-lifting device. The detection data of the anemometer can be transmitted to a remote mobile terminal. Thus, the user can know the current wind speed at any time. The wind-powered seawater uranium extraction system also includes a manual locking device. When the wind is strong, the windmill will automatically stop running to prevent excessive water flow in the system and prevent the windmill from being damaged. When the wind force increases further, the staff will need to manually lock the windmill.

[0048] In order to improve the service life of the wind-powered seawater uranium extraction system, the parts in contact with seawater are preferably made of polymer materials. For example, the water bucket 4, each water pipe, the first solenoid valve 42, the second solenoid valve 45 are made of polymer materials or the parts in contact with seawater are made of polymer materials.

[0049] When the number of the middle section water pipes is multiple, it can be selected to be 2 to 5. This can increase the water intake of the water bucket 4, reduce the internal pressure of the system, and extend the operating time of the system.

[0050] The pressure data detected by the pressure gauge is used by users to monitor system operation. If the pressure is too high, it indicates that there may be a blockage in the system and it needs to be checked, cleaned or replaced.

[0051] The critical pressure of the pressure relief valve is manually set by the user. The system pressure of the wind turbine during normal operation is 0.1-0.5MPa. If the pressure exceeds this range, the pressure relief valve will automatically discharge water to relieve the pressure.

[0052] exist Figure 1 In the illustrated embodiment, the water storage capacity of the water bucket 4 is 4 tons, the height is 2 meters, and there are high and low liquid level alarms at 30 cm from the upper and lower ends of the water bucket 4. The second solenoid valve 45 is linked to the high and low liquid level alarms. When the seawater level in the water bucket 4 is greater than or equal to the highest liquid level, the second solenoid valve 45 automatically opens; when the seawater level in the water bucket 4 is less than or equal to the lowest liquid level, the second solenoid valve 45 automatically closes. In this way, the seawater in the water bucket 4 is prevented from running dry, and the seawater flow rate in the adsorption bed 5 is ensured to be stable at a relatively stable and large value. The second solenoid valve 45 has two modes, manual and automatic, and can be remotely controlled by a program.

[0053] The protection scope of the present invention is not limited to the above-mentioned embodiments. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the scope and spirit of the present invention. If these changes and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these changes and modifications.
