[0031] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0032] In the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0033] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0035] In hydrometallurgy, when the adsorption method is used for selective separation and extraction of mineral resources, due to uneven water distribution, the adsorbents in areas with large water flow rates are often severely damaged, while those in areas with small water flow rates are less damaged. This affects the extraction rate of the minerals and makes it inconvenient to replace the adsorbents.

[0036] To improve the above problems, the embodiment of the present application provides a water distribution device 100, which can be used for uniform water distribution during mineral extraction. The water distribution device 100 provided in the present application can ensure uniform distribution of brine, ensure uniform mineral adsorption in different areas, and improve the extraction rate.

[0037] The water distribution device 100 includes a housing 110, a water filter layer 130 and a plurality of spoilers 120. The housing 110 is provided with a housing cavity 111, a mixing area 1111 and a water distribution area 1112 are provided in the housing cavity 111, a plurality of water inlets 112 are provided on the peripheral side of the housing 110, and the water inlets 112 are connected to the mixing area 1111; the water filter layer 130 is provided in the water distribution area 1112, and the water filter layer 130 is used to uniformly infiltrate the mixed solution in the mixing area 1111; the spoiler 120 is provided in the mixing area 1111, and the plurality of spoilers 120 define a plurality of flow channels in the housing 110.

[0038] like Figure 1 As shown, the housing 110 can be a trough-shaped structure with a receiving cavity 111. After the water distribution device 100 is placed in the packed bed, a closed operation area is formed. In this embodiment, the housing 110 is a rectangular trough.

[0039] The accommodating cavity 111 is divided into a mixing zone 1111 and a water distribution zone 1112 in sequence along the length direction of the shell 110. The mixing zone 1111 is located at the end of the shell 110 and is used to mix and decompress the brine raw materials to be processed. The water distribution zone 1112 is arranged adjacent to the mixing zone 1111, and the decompressed brine is uniformly seeped through the water distribution zone 1112. The water inlet 112 is arranged at one end of the shell 110 where the mixing zone 1111 is arranged, and the water inlet 112 is connected to the mixing zone 1111, so that the external brine is injected into the shell 110.

[0040] In this embodiment, two water inlets 112 are provided, and the two water inlets 112 are relatively arranged on both sides of the shell 110, and the diameters of the two water inlets 112 are the same to ensure that the water flow rate of the two water inlets 112 is the same, and the solutions are counteracted in the mixing area 1111 to generate turbulence and mix the brine evenly.

[0041] In other embodiments, the housing 110 may also be a closed cylindrical structure, in which case the number of water inlets 112 may be two, three, four, five, etc., which may be selected according to actual needs. The multiple water inlets 112 are evenly distributed around the housing 110 to form water flow counterflow.

[0042] The spoiler 120 is arranged on the side of the mixing zone 1111 close to the water distribution zone 1112, and the water inlet 112 is located on the side of the mixing zone 1111 away from the water distribution zone 1112, so as to ensure that the water flow can be mixed under the water distribution zone 1112. The water flow mixes and flows toward the spoiler 120, and the spoiler 120 can buffer the water flow, thereby reducing the pressure on the water inlet side of the water filter layer 130. Multiple spoilers 120 form multiple flow channels in the housing 110, and the water flows into the water filter layer 130 through different flow channels to achieve uniform distribution of brine.

[0043] Combination Figure 1 and Figure 2 As shown, in some embodiments, an adsorption area 1113 is further provided in the accommodating cavity 111 , and the adsorption area 1113 is located on a side of the water filtering layer 130 away from the mixing area 1111 . The adsorption area 1113 is provided with a filling member 140 , and the filling member 140 is filled with an adsorbent.

[0044] Exemplarily, the housing 110 is provided with a drain port 113 at one end of the adsorption area 1113, and the adsorption area 1113 extracts the required mineral ions through adsorption of the adsorbent. The filler 140 can be a basket or box structure, which contains the adsorbent, and has openings 141 on both sides to communicate with the accommodating cavity 111, so that the mixed brine flows into the adsorbent, and after the adsorption is completed, the waste liquid is discharged from the drain port 113.

[0045] In some embodiments, the ratio of the total cross-sectional area of ​​all water inlets 112 to the cross-sectional area of ​​the adsorption area 1113 is 1 / 10 to 1 / 2.

[0046] Exemplarily, the total cross-sectional area of ​​all water inlets 112 reflects the water inflow rate of brine, and the ratio of the total cross-sectional area of ​​all water inlets 112 to the cross-sectional area of ​​the adsorption zone 1113 is: 1 / 10, 1 / 9, 1 / 8, 1 / 7, 1 / 6, 1 / 5, 1 / 4, 1 / 3, 1 / 2, etc. The corresponding ratio can be adjusted according to the actual absorption rate, but generally the total cross-sectional area of ​​the water inlet 112 should be smaller than the cross-sectional area of ​​the adsorption zone 1113 to avoid excessive water inflow and exceeding the absorption rate of the adsorbent.

[0047] Combination Figure 6 and Figure 7 As shown, in some embodiments, the spoiler 120 is a hollow pipe or a trough plate arranged parallel to the first direction y, and the first direction y is parallel to the water distribution direction of the water distribution area 1112.

[0048] Exemplarily, due to the provision of the spoiler 120 , the turbulence generated by the water flow is buffered, so that the water flow is decelerated and flows from each flow channel to the water distribution area 1112 , which facilitates uniform water distribution in the water filter layer 130 .

[0049] When the spoiler 120 is a hollow pipe, the multiple pipes are distributed in an array along the second direction x, and the cavity of each pipe is a flow channel.

[0050] When the spoiler 120 is a slot plate, a plurality of slot plates are distributed in an array along the second direction x, and the slot plates are fixedly disposed in the housing 110 , so that a plurality of flow channels are formed between the slot plates and the housing 110 and between two adjacent slot plates.

[0051] Combination Figure 6 and Figure 7 As shown, in some embodiments, the shape of the flow channel includes at least one of the following: rectangular, circular, and serpentine.

[0052] For example, when the spoiler 120 is a hollow pipe or a groove plate, the cross section of the flow channel can be limited to a polygon or a circle, and in some cases, it can also be an irregular shape.

[0053] In the present application, serpentine means that the pipe wall or the groove plate of the pipeline presents a continuous broken line or curved line structure, thereby forming a winding flow channel structure.

[0054] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the spoiler 120 is a flow column or a blocking plate, and a plurality of spoilers 120 are distributed in an array along the second direction x, and the second direction x is perpendicular to the water distribution direction of the water distribution area 1112 .

[0055] Exemplarily, the spoiler 120 is arranged perpendicular to the groove wall of the housing 110 to form a patterned flow channel. When the water flows toward the water distribution area 1112, it needs to bypass the spoiler 120, thereby reducing the water flow speed.

[0056] The spoiler 120 may have various structural arrangements, such as Figure 3 The cylindrical rods shown are arranged in an array along the second direction x, and multiple layers can be arranged along the first direction y. The spoilers 120 of two adjacent layers are staggered. Through the interval arrangement of the spoilers 120, multiple flow channels are separated and formed in the housing 110. Figure 4 and Figure 5 The plate-like structure shown, wherein Figure 4 It is a curved plate structure. Figure 5 It is a flat plate structure and can achieve a buffering effect on water flow.

[0057] In some embodiments, the water filter layer 130 is a sponge.

[0058] Exemplarily, the sponge is a porous material with good water absorption, so it absorbs brine, and the resistance to water in each part is consistent, so that the brine can penetrate into the adsorption area 1113 evenly.

[0059] Specifically, the sponge material can be one of polyurethane, polypropylene, and polyvinyl chloride.

[0060] In some embodiments, the density of the sponge is 0.01 to 0.1 g / cm 3 .

[0061] For example, the density of the sponge may be 0.01 g / cm 3 , 0.02g / cm 3 , 0.03g / cm 3 , 0.04g / cm 3 , 0.05g / cm 3 , 0.06g / cm 3 , 0.07g / cm 3 , 0.08g / cm 3 , 0.09g / cm 3 , 0.1g / cm 3 Etc. You can choose according to actual needs.

[0062] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in the present application, the adsorption area 1113 can be divided into three areas A, B, and C, wherein area B is located in the middle, and areas A and C are located on the sides, and the adsorption and volatilization amount of each area is obtained through control experiments.

After 4 hours of reaction, the adsorbent capacity of area A is 81.3%, the adsorbent capacity of area B is 82.1%, and the capacity of area C is 81.8%.

After 4 hours of reaction, the adsorbent capacity of area A is 71.2%, the adsorbent capacity of area B is 78.1%, and the capacity of area C is 73.8%.

[0065] In a comparative embodiment, the cross-sectional flow rate of the adsorption zone 1113 is 5 cm / s, the total cross-sectional area of ​​the water inlet 112 is 1 / 2 of the adsorption zone 1113, no flow channel and water filter layer 130 are set, and after the reaction is carried out for 4 hours, the adsorbent capacity of the A region is 76.0%, the adsorbent capacity of the B region is 54.1%, and the capacity of the C region is 71.9%.
