[0024] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] In related technologies, hydrometallurgy involves contacting ores, beneficiated concentrates, or other raw materials with aqueous solutions or other liquid phases. Through chemical reactions, the useful metals contained in the raw materials are transferred into the liquid phase. The various useful metals in the liquid phase are then separated and concentrated, and finally recovered as metals or other compounds. The mixing equipment is a core component of hydrometallurgy; its performance directly determines the material reaction efficiency, metal recovery rate, and product purity. It is widely used in core processes such as slurry mixing and reaction promotion. Typically, the mixing devices used in hydrometallurgy are single-compartment mixers. This often results in short contact times between the material and the reaction solution, leading to incomplete reactions and affecting metal recovery rates.

[0026] Please refer to Figure 1 As shown, an embodiment of this application provides a tower-type stirring device 100, which includes a tower assembly 110, a stirring assembly 120, and a plurality of sampling elements 130.

[0027] Specifically, in combination Figure 1 and Figure 2 As shown, a plurality of stirring chambers 111 are defined within the tower assembly 110. The plurality of stirring chambers 111 are arranged sequentially along the height direction, and liquid communication is maintained between two adjacent stirring chambers 111. A feed component 112 and a discharge component 113 are respectively provided at opposite ends of the tower assembly 110. The feed component 112 and the discharge component 113 correspond to one stirring chamber 111. The material of hydrometallurgy enters the stirring chamber 111 through the feed component 112 and is stirred and mixed with the reaction solution to form a slurry solution.

[0028] In this embodiment, as Figure 2 As shown, the stirring assembly 120 includes a stirring shaft 121 and multiple stirring elements 122. The stirring shaft 121 is rotatably connected to the tower assembly 110. The multiple stirring elements 122 are respectively installed on the stirring shaft 121. Each stirring element 122 corresponds to a stirring chamber 111. Each sampling element 130 corresponds to a stirring chamber 111. Each stirring element 122 corresponds to a stirring chamber 111. Any stirring chamber 111 can realize the stirring and mixing of the solution. Each sampling element 130 corresponds to a stirring chamber 111 to facilitate sampling and monitoring of the state of the slurry solution in the stirring chamber 111. The slurry solution can pass through the multiple stirring chambers 111 of the tower assembly 110 in sequence to facilitate the step-by-step stirring of the slurry solution and output it through the discharge element 113, which promotes the full stirring and mixing of the slurry solution, prolongs the reaction time of the material, and thus improves the stirring reaction effect of the tower stirring device 100.

[0029] For example, the stirring assembly 120 also includes a stirring motor 123, which is connected to the stirring shaft 121 and can drive the stirring shaft 121 to rotate relative to each other. The stirring motor 123 can be a rotary motor.

[0030] The slurry solution is sequentially stirred through multiple mixing chambers 111 and then discharged from the discharge port 113. This promotes the full integration of materials and reaction solution, enhances the reaction effect, and improves the material conversion rate. It meets the requirements of high efficiency and continuous operation of the tower mixing device 100 and is suitable for hydrometallurgical production scenarios. Compared with traditional mixing methods, it can improve production efficiency and product quality, while reducing the equipment footprint and optimizing the production layout.

[0031] refer to Figure 1 and Figure 2 As shown, the tower-type mixing device 100 has a first direction X. For example, the first direction X is taken as the height direction of the tower-type mixing device 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts in the tower-type mixing device 100 and should not be construed as limitations on this application.

[0032] In one embodiment, alternatively, such as Figure 1 As shown, each of the sampling elements 130 along the height direction is located at the middle position of the corresponding mixing chamber 111, and the distances from each sampling element 130 to both ends of the mixing chamber 111 along the height direction are the same. Positioning the sampling element 130 at the middle position of the mixing chamber 111 avoids the upper and lower stratified areas of the slurry solution within the mixing chamber 111, ensuring that the sampled slurry solution accurately reflects the overall mixing state and reaction progress of the slurry solution within the mixing chamber 111, and avoiding data distortion caused by sampling position deviations. The equidistant distances of the sampling element 130 to both ends of the mixing chamber 111 allow for the collection of slurry solution from the middle position of the mixing chamber 111 during sampling, further improving the representativeness of the sample and the accuracy of the monitoring data. This provides reliable data support for personnel to control the reaction process, ensuring the stability and consistency of the entire reaction process, and ultimately improving the stability of product quality.

[0033] In summary, the hydrometallurgical material of the tower-type stirring device 100 enters the stirring chamber 111 through the feed component 112 and is stirred and mixed with the reaction solution to form a slurry solution. Each stirring component 122 corresponds to one stirring chamber 111, and any stirring chamber 111 can achieve stirring and mixing of the solution. Each sampling component 130 is set to correspond to one stirring chamber 111 to facilitate sampling and monitoring of the state of the slurry solution in the stirring chamber 111. The slurry solution can pass through multiple stirring chambers 111 of the tower assembly 110 in sequence to facilitate step-by-step stirring of the slurry solution before being output through the discharge component 113. This promotes thorough stirring and mixing of the slurry solution, prolongs the reaction time of the material, improves the stirring reaction effect of the tower-type stirring device 100, and thus improves the metal recovery rate.

[0034] refer to Figure 1 As shown, an embodiment of this application provides another tower-type stirring device 100, which includes a tower assembly 110, a stirring assembly 120, and a plurality of sampling elements 130.

[0035] Specifically, in combination Figure 1 and Figure 2As shown, a plurality of stirring chambers 111 are defined within the tower assembly 110. The stirring chambers 111 are arranged sequentially along the height direction, with liquid communication between adjacent stirring chambers 111. A feed component 112 and a discharge component 113 are respectively provided at opposite ends of the tower assembly 110. Each feed component 112 and discharge component 113 corresponds to one stirring chamber 111. The stirring assembly 120 includes a stirring shaft 121 and a plurality of stirring elements 122. The stirring shaft 121 is rotatably connected to the tower assembly 110. The plurality of stirring elements 122 are respectively mounted on the stirring shaft 121, with each stirring element 122 corresponding to one stirring chamber 111. Each sampling element 1... Each of the three components 122 and 130 corresponds to one of the mixing chambers 111. The hydrometallurgical material enters the mixing chamber 111 through the feed component 112 and is mixed with the reaction solution to form a slurry solution. Each mixing component 122 corresponds to one mixing chamber 111. Any mixing chamber 111 can achieve the mixing of the solution. Each sampling component 130 corresponds to one mixing chamber 111 to facilitate the sampling and monitoring of the state of the slurry solution in the mixing chamber 111. The slurry solution can pass through multiple mixing chambers 111 of the tower assembly 110 in sequence to facilitate the step-by-step mixing of the slurry solution and then be output through the discharge component 113. This promotes the full mixing of the slurry solution, prolongs the reaction time of the material, and thus improves the mixing reaction effect of the tower mixing device 100.

[0036] In one embodiment, alternatively, such as Figure 1 As shown, any sampling element 130 along the height direction is located in the middle of the corresponding mixing chamber 111, and the distance from each sampling element 130 to both ends of the mixing chamber 111 along the height direction is the same. Positioning the sampling element 130 in the middle of the mixing chamber 111 avoids the upper and lower stratified areas of the slurry solution within the mixing chamber 111, ensuring that the sampled slurry solution accurately reflects the overall mixing state and reaction progress of the slurry solution within the mixing chamber 111, and avoiding data distortion caused by sampling position deviation. The equidistant distance from the sampling element 130 to both ends of the mixing chamber 111 allows for the collection of slurry solution from the middle position of the mixing chamber 111, further improving the representativeness of the sample and the accuracy of the monitoring data. This provides reliable data support for personnel to control the reaction process, ensuring the stability and consistency of the entire reaction process, and ultimately improving the stability of product quality.

[0037] In one embodiment, alternatively, referencing Figure 2As shown, the feed component 112 is located in a mixing chamber 111 near the bottom of the tower assembly 110, and the discharge component 113 is located in a mixing chamber 111 near the top of the tower assembly 110. This arrangement of bottom feeding and top discharge allows the slurry solution to flow upwards from the bottom mixing chamber 111, passing through all the mixing chambers 111 in sequence to complete the step-by-step mixing reaction. The upward flow direction of the slurry solution, combined with the stirring action of the agitator 122, can prolong the residence time of the slurry solution in each mixing chamber 111, ensuring sufficient contact between the material and the reaction solution, avoiding the situation where the material is discharged without sufficient reaction, and further improving the mixing reaction effect and material conversion rate.

[0038] In one embodiment, alternatively, such as Figure 1 and Figure 2 As shown, the tower-type mixing device 100 also includes multiple partitions 115. The tower assembly 110 includes multiple cylinders 114, and two adjacent cylinders 114 are separated by a partition 115 to form a mixing chamber 111. The partitions 115 separate the multiple cylinders 114 into multiple independent mixing chambers 111, realizing a modular design of the mixing chambers 111. This allows the number and height of the mixing chambers 111 to adapt to different material processing volumes and reaction requirements, improving the versatility and flexibility of the device. The partitions 115 can effectively separate the slurry solution in each mixing chamber 111, ensuring that each mixing chamber 111 can achieve independent mixing reaction and ensuring the effect of step-by-step mixing. At the same time, the partitions 115 facilitate the disassembly, installation, and maintenance of the equipment. When a cylinder 114 or a partition 115 is damaged, it can be disassembled and replaced individually, reducing maintenance difficulty and cost, and improving the overall performance of the equipment.

[0039] Further, refer to Figure 3As shown, each of the partition members 115 is provided with multiple connection holes 1151, which are distributed circumferentially along the partition member 115. The connection holes 1151 enable liquid communication between adjacent mixing chambers 111, ensuring that the slurry solution can flow smoothly from the next mixing chamber 111 to the next mixing chamber 111, ensuring the step-by-step mixing process. The multiple connection holes 1151 are evenly distributed circumferentially along the partition member 115, which can make the slurry solution evenly distributed during the flow process, avoiding local excessive flow velocity or stagnation, and ensuring the slurry solution... After the solution enters the next stage mixing chamber 111, it can have a large contact area with the stirring element 122 in the chamber, achieving uniform stirring and further improving the uniformity of the stirring reaction. At the same time, the circumferentially distributed connecting holes 1151 can disperse the flow impact force of the slurry solution, and the setting of connecting holes 1151 reduces the influence of the partition 115 on the separation effect of each mixing chamber 111, taking into account both the flow of solution and the independence of the mixing chamber 111, avoiding the complete blockage of the connecting channels by solid particles in the slurry solution, ensuring unobstructed liquid channels, and guaranteeing the continuous and stable operation of the stirring device.

[0040] Furthermore, such as Figure 2 As shown, the partition 115 has a conical structure, and each partition 115 is provided with a central hole 1152. The central hole 1152 is located at the tip of the cone of the partition 115. Each central hole 1152 is oriented towards one of the stirring components 122. The stirring shaft 121 passes through the central hole 1152, and a gap is formed between the stirring shaft 121 and the wall of the central hole 1152. During the rotation of the stirring component 122, a vortex is formed in the stirring chamber 111. The cone of the partition 115 has a conical structure. A central hole 1152 is provided at the pointed position. The conical baffle 115 allows the gas to converge more easily to the cone tip area under the action of vortex, avoiding the gas from being dispersed in the mixing chamber 111, improving the uniformity of gas-liquid mixing, and facilitating the entry of slurry solution and gas from the lower mixing chamber 111 to the upper mixing chamber 111 through the central hole 1152. This achieves orderly circulation of slurry and gas between each mixing chamber 111, avoids blockage, ensures smooth flow of slurry and gas between each mixing chamber 111, and thus improves the mixing effect.

[0041] Optionally, such as Figure 2 and Figure 3As shown, the tower-type mixing device 100 also includes a sealing assembly 140, which includes a first sealing element 141 and a second sealing element 142. The first sealing element 141 abuts against one side of the partition 115 between one of the cylinders 114, and the second sealing element 142 abuts against the side of the partition 115 away from the first sealing element 141 between the other cylinder 114. Through the double sealing arrangement of the first sealing element 141 and the second sealing element 142, the gap between the partition 115 and the adjacent cylinder 114 can be effectively sealed, preventing the slurry solution from leaking or flowing out from the gap, ensuring the independent mixing reaction effect of each mixing chamber 111, improving the sealing reliability, and the setting of the sealing assembly 140 can prevent the slurry solution leakage from causing corrosion and wear to other parts of the equipment, extending the overall service life of the equipment, and reducing the equipment maintenance cost.

[0042] For example, the first seal 141 can be a sealing ring, and the second seal 142 can be a sealing ring.

[0043] In one embodiment, alternatively, referencing Figure 2 As shown, the tower-type stirring device 100 also includes an air inlet assembly 150, which is disposed in a stirring chamber 111 near the bottom of the tower assembly 110. By placing the air inlet assembly 150 in the bottom stirring chamber 111, the gas can be mixed with the slurry solution from the initial stirring stage and fully contact and mix with the slurry solution during the staged stirring process, thereby improving the dissolution efficiency of the gas in the slurry solution and meeting the demand for gas (such as oxygen, reaction gas, etc.) during the reaction process. The bottom air inlet can take advantage of the rising gas characteristics and cooperate with the stirring action of the stirring element 122 to further enhance the stirring effect, avoid the slurry solution from stratification and precipitation, and improve the uniformity of material mixing.

[0044] Furthermore, the air intake assembly 150 includes an air intake coil 151 and an air intake valve 152. The air intake valve 152 is connected to the input end of the air intake coil 151. The air intake coil 151 has multiple air outlets arranged around its circumference. The arrangement of the air intake coil 151 increases the contact area between the gas and the slurry solution. Combined with the multiple air outlets distributed around its circumference, the gas can be evenly and dispersedly introduced into the slurry solution, ensuring that the gas and the slurry solution are fully mixed, improving the gas dissolution efficiency and reaction rate. The air intake valve 152 can adjust the air intake volume. The operator can flexibly adjust the flow rate of the incoming gas according to the progress and needs of the stirring reaction to adapt to different reaction stages, ensuring that the reaction proceeds efficiently and stably. In addition, the air intake valve 152 can prevent the slurry solution from flowing back into the air intake coil 151, ensuring the normal operation of the air intake assembly 150. The air inlet coil 151 is arranged around the bottom mixing chamber 111 and can cooperate with the agitator 122 in the bottom mixing chamber 111 to make the gas quickly diffuse to the entire mixing chamber 111 under the agitation action, further improving the mixing effect of gas and slurry solution. At the same time, the structure of the air inlet coil 151 avoids interference with the agitator 122, ensuring the safety and stability of equipment operation.

[0045] In one embodiment, alternatively, such as Figure 2 As shown, the tower-type stirring device 100 also includes a heating element 160, which is disposed in a stirring chamber 111 near the bottom of the tower assembly 110. The heating element 160 is arranged around the stirring element 122, and the heating element 160 and the stirring element 122 are spaced apart. Placing the heating element 160 in the bottom stirring chamber 111 allows for heating of the slurry solution from the initial stage, shortening the reaction start-up time and improving production efficiency. The surrounding arrangement of the heating element 160 ensures that heat is evenly distributed throughout the stirring chamber 111, avoiding localized overheating or underheating, and ensuring that the slurry solution is stirred and reacted within a suitable temperature range, thus improving reaction efficiency and product quality. A gap is left between the heating element 160 and the stirring element 122 to prevent interference or collision between the stirring element 122 and the heating element 160 during rotation. Simultaneously, the stirring action of the stirring element 122 drives the flow of the slurry solution, accelerating heat transfer and improving heating uniformity and efficiency.

[0046] For example, the intake coil 151 is located below the heating element 160.

[0047] Optionally, the mixing chamber 111 is equipped with a baffle plate, which can be fixedly connected to the inner wall of the cylinder. The baffle plate can break the eddy inertia formed by the rotation of the agitator, avoid local circulation and mixing dead zones in the slurry solution in the mixing chamber, improve the mixing uniformity of slurry and gas, enhance the shear force during the mixing process, help the slurry to be fully dispersed, and form a synergistic effect with the gas-liquid aggregation effect of the baffle plate.

[0048] Embodiments of the present invention also provide a stirring system, including the tower stirring device 100 described in any of the above embodiments. The stirring system including the tower stirring device 100 has all the beneficial effects of the tower stirring device 100, which will not be described in detail here.

[0049] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0050] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
