[0029] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the related drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thorough and comprehensive.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0033] like Figure 1 As shown, an embodiment of the nickel-iron alloy 10 dissolving apparatus includes a reaction vessel 100, a stirring assembly 200, a supporting sieve plate 300, and a steam conduit 400. The reaction vessel 100 is used to contain the nickel-iron alloy 10 and the reaction acid solution that immerses the nickel-iron alloy 10. The stirring assembly 200 is used to be mounted on a fixed frame (not shown). The stirring paddle 210 of the stirring assembly 200 extends into the reaction vessel 100 and is used to stir the nickel-iron alloy 10 and the reaction acid solution. The supporting sieve plate 300 is disposed between the stirring paddle 210 and the bottom wall of the reaction vessel 100, and is used to support the nickel-iron alloy 10. The steam conduit 400 is disposed inside the reaction vessel 100, and the exhaust end of the steam conduit 400 is connected to the inside of the reaction vessel 100. The steam conduit 400 is used to introduce steam into the reaction vessel 100 so that the steam pushes the nickel-iron alloy 10 to float toward the stirring paddle 210.

[0034] It is understandable that, since the supporting sieve plate 300 is set between the stirring paddle 210 and the bottom wall of the reaction vessel 100, the supporting sieve plate 300 can support the alloy blocks that have settled to the bottom of the nickel-iron alloy 10. The steam pipe 400 is set inside the reaction vessel 100, and the exhaust end of the steam pipe 400 is connected to the reaction vessel 100, so that steam can be introduced into the reaction vessel 100 through the steam pipe 400. The steam acts on the alloy blocks that have settled to the bottom, and the steam pressure pushes the alloy blocks that have settled to the bottom to float towards the stirring paddle 210. In this way, the stirring paddle 210 can drive more alloy blocks in the nickel-iron alloy 10 to mix and react with the reaction acid, ultimately achieving the effect of reducing the overall dissolution time of the nickel-iron alloy 10, increasing the dissolution rate, and reducing the overall unit consumption.

[0035] CombinationFigure 1 As shown, in the present embodiment, a bottom layer cavity 301 is formed between the supporting sieve plate 300 and the bottom wall of the reaction vessel 100; the exhaust end of the steam conduit 400 penetrates through the supporting sieve plate 300 and communicates with the bottom layer cavity 301; the bottom layer cavity 301 is opposite to the position of the stirring paddle 210 through the sieve hole of the supporting sieve plate 300. It can be understood that, since the exhaust end of the steam conduit 400 communicates with the bottom layer cavity 301 formed between the supporting sieve plate 300 and the bottom wall of the reaction vessel 100, steam can be introduced into the bottom layer cavity 301 through the steam conduit 400, and the steam forms bubbles in the bottom layer cavity 301, and since the bottom layer cavity 301 is opposite to the position of the stirring paddle 210 through the sieve hole of the supporting sieve plate 300, the bubbles can push the nickel-iron alloy 10 on the supporting sieve plate 300 to float more quickly towards the stirring paddle 210 through the sieve hole of the supporting sieve plate 300.

[0036] In combination Figures 1 to 3 As shown, in some embodiments, a plurality of exhaust tear holes 411 are spaced apart on the exhaust end of the steam conduit 400, and the exhaust end of the steam conduit 400 communicates with the bottom layer cavity 301 through at least one exhaust tear hole 411. It can be understood that, since the exhaust end of the steam conduit 400 communicates with the bottom layer cavity 301 through a plurality of exhaust tear holes 411 on the exhaust end of the steam conduit 400, the steam introduced by the steam conduit 400 can be dispersed into a plurality of gas streams through each exhaust tear hole 411, and the dispersed plurality of gas streams can make the overall pushing force on the bottom-sinking alloy block more uniform.

[0037] In combination Figure 2 With Figure 3 As shown, in some embodiments, the plurality of exhaust tear holes 411 are divided into a plurality of tear hole groups 410, and the plurality of tear hole groups 410 are spaced apart along the axial direction of the steam conduit 400; and each exhaust tear hole 411 in the same tear hole group 410 is spaced apart on the circumferential direction of the radial cross section of the steam conduit 400. It can be understood that, since the plurality of tear hole groups 410 are spaced apart along the axial direction of the steam conduit 400, the steam can be more uniformly dispersed in the length direction of the steam conduit 400, and since each exhaust tear hole 411 in the same tear hole group 410 is spaced apart on the circumferential direction of the radial cross section of the steam conduit 400, the steam can be more uniformly dispersed in the circumferential direction of the steam conduit.

[0038] In combination Figure 1As shown, in the embodiment, the steam conduit 400 has an inlet end located outside the reaction container 100 for being communicated with a steam source, and has an outlet end penetrating through the supporting sieve plate 300 and being accommodated in the bottom layer cavity 301. It can be understood that, since the steam conduit 400 has the inlet end located outside the reaction container 100 and the outlet end accommodated in the bottom layer cavity 301, the steam source outside the reaction container 100 can be introduced into the bottom layer cavity 301 through the steam conduit 400 to enhance the effect on the alloy blocks sinking to the bottom.

[0039] In combination Figure 1 As shown, in some embodiments, the reaction container 100 is further provided with a support seat 110 on the bottom wall, and the supporting sieve plate 300 is arranged on the support seat 110. It can be understood that, since the supporting sieve plate 300 is arranged on the support seat 110 of the bottom wall of the reaction container 100, the load bearing capacity of the supporting sieve plate 300 on the alloy blocks sinking to the bottom in the ferronickel alloy 10 can be improved through the support seat 110.

[0040] In combination Figure 1 , Figure 4 With Figure 5 As shown, in the embodiment, the support seat 110 includes at least two support columns 111, and each support column 111 has two ends connected to the supporting sieve plate 300 and the bottom wall of the reaction container 100, respectively. It can be understood that, since each support column 111 in the support seat 110 has two ends connected to the supporting sieve plate 300 and the bottom wall of the reaction container 100, respectively, the supporting action on the local position of the supporting sieve plate 300 can be formed by supporting the supporting sieve plate 300 through each support column 111, thereby improving the load bearing capacity of the whole supporting sieve plate 300.

[0041] In combination Figure 1 As shown, in some embodiments, the reaction container 100 is further provided with a circulating pipeline 150 outside, and the circulating pipeline 150 is installed with a push pump 151; the inlet end of the circulating pipeline 150 is located at the bottom of the reaction container 100 and is communicated with the bottom layer cavity 301; and the outlet end of the circulating pipeline 150 is located at the top of the reaction container 100 and is communicated with the inside of the reaction container 100. It can be understood that, since the inlet end of the circulating pipeline 150 is communicated with the bottom layer cavity 301 and the outlet end of the circulating pipeline 150 is located at the top of the reaction container 100 and is communicated with the inside of the reaction container 100, the solution in the bottom layer cavity 301 can be pushed to the top of the reaction container 100 by the push pump 151 to flow back to the inside of the reaction container 100, so that the solution circulation in the reaction container 100 can be increased, the flowability of the reaction acid liquid can be increased, and the reaction rate can be improved.

[0042] In combination Figure 1 With Figure 5As shown, in some embodiments, the reaction container 100 is provided with a thermal insulation layer 120, which is wrapped around the outer sidewall of the reaction container 100. It can be understood that, since the thermal insulation layer 120 is wrapped around the outer sidewall of the reaction container 100, after the steam is introduced into the reaction container 100 through the steam conduit 400, the thermal insulation layer 120 can reduce the loss of heat in the steam, thereby increasing the temperature of the ferronickel alloy 10 and the reaction acid solution, so as to further improve the reaction rate and reduce energy consumption.

[0043] In combination Figure 1 As shown, in some embodiments, the sidewall of the reaction container 100 is provided with a temperature monitoring meter 130, which is arranged close to the support sieve plate 300. It can be understood that, by installing the temperature monitoring meter 130 on the sidewall of the reaction container 100, so that the temperature monitoring meter 130 is arranged close to the support sieve plate 300, compared with the traditional installation mode of inserting from the top of the reaction container 100, the temperature monitoring meter 130 of the present embodiment can not only more accurately measure the temperature of the ferronickel alloy 10 and the reaction acid solution on the support sieve plate 300, but also can monitor the temperature when the liquid level in the reaction container 100 is lowered. At the same time, the temperature monitoring meter 130 can also be designed to be shorter in structure, which can reduce the configuration of the sleeve outside the traditional temperature monitoring meter 130, and the risk of damage to the temperature monitoring meter 130 is also lower.

[0044] In combination Figure 5 As shown, in some embodiments, the inner wall of the reaction container 100 is provided with a plurality of baffles 140, which are distributed around the stirring paddle 210; the edge of the support sieve plate 300 is fixedly connected to the inner wall of the reaction container 100 and each baffle 140. It can be understood that, since the plurality of baffles 140 are distributed around the stirring paddle 210, when the stirring paddle 210 rotates to stir and mix the ferronickel alloy 10 and the reaction acid solution, the baffles 140 can reduce the generation of vortex in the reaction acid solution, thereby making the mixing of the ferronickel alloy 10 and the reaction acid solution more uniform. At the same time, since each baffle 140 is fixedly connected to the edge of the support sieve plate 300, the position of the support sieve plate 300 can be limited to avoid loosening of the support sieve plate 300 in the reaction container 100.

[0045] In combination Figure 6As shown, in some embodiments, the top of the reaction container 100 is provided with a feeding port 101 and a liquid inlet 102, and the side wall of the reaction container 100 is provided with a product outlet 103. The feeding port 101 is used to put the ferronickel alloy 10 into the reaction container 100, the liquid inlet 102 is used to introduce the reaction acid liquid into the reaction container 100, and the product outlet 103 is used to discharge the product solution obtained after the ferronickel alloy 10 reacts with the reaction acid liquid. It can be understood that the ferronickel alloy 10 is put into the reaction container 100 through the feeding port 101, the reaction acid liquid is put into the reaction container 100 through the liquid inlet 102 so that the ferronickel alloy 10 and the reaction acid liquid are mixed in the reaction container 100, and finally the product solution obtained after the ferronickel alloy 10 reacts with the reaction acid liquid is discharged through the product outlet 103.

[0046] In some embodiments, in order to facilitate better understanding, the use process of the ferronickel alloy dissolving device in the above embodiments is described as follows:

[0047] In combination Figure 1 With Figure 6 As shown, in use, the reaction acid liquid is first added through the liquid inlet 102 to immerse the stirring paddle 210, then the ferronickel alloy 10 is put in through the feeding port 101, and then steam is introduced through the steam conduit 400 and the stirring assembly 200 is started. The steam enters the reaction container 100 through the steam conduit 400, the gas pressure of the steam pushes the ferronickel alloy 10 on the supporting sieve plate 300 to fully contact with the reaction acid liquid, and the stirring paddle 210 above the supporting sieve plate 300 drives the ferronickel alloy 10 and the reaction acid liquid to mix and react.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] The ferronickel alloy dissolving device described above, since the supporting sieve plate 300 is arranged between the stirring paddle 210 and the bottom wall of the reaction container 100, the alloy blocks that sink to the bottom of the ferronickel alloy 10 can be carried by the supporting sieve plate 300, the steam conduit 400 is arranged in the reaction container 100, and the exhaust end of the steam conduit 400 communicates with the reaction container 100, so that steam can be introduced into the reaction container 100 through the steam conduit 400. The steam acts on the alloy blocks that sink to the bottom to push the alloy blocks that sink to the bottom to float towards the stirring paddle 210 by the pressure of the steam, thereby enabling the stirring paddle 210 to drive more alloy blocks in the ferronickel alloy 10 to mix and react with the reaction acid liquid, and ultimately achieving the effects of reducing the overall dissolution time of the ferronickel alloy 10, improving the dissolution rate, and reducing the overall unit consumption.

[0050] The above-described embodiments only express several implementation manners of the present disclosure, which are described in a more specific and detailed manner, but cannot be understood as a limitation on the scope of the utility model patent. It should be noted that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present disclosure, which all belong to the protection scope of the present disclosure.
