Description

Technical Field

[0001] The utility model relates to the technical field of indium extraction by substitution method, in particular to an indium extraction substitution tank. Background Art

[0002] In industry, zinc powder replacement is commonly used to replace indium in indium-containing solutions to obtain sponge indium. The principle is that the electronegativity of metallic zinc is greater than that of metallic indium. Zinc powder will reduce indium ions in the solution to obtain sponge-like elemental indium, while zinc powder will be oxidized and enter the solution. Since the amount of zinc powder added is difficult to accurately control, in order to replace as much indium as possible in the solution, an excess of zinc powder needs to be added. At the same time, since the replaced indium is in the form of a sponge, it needs to be manually scooped out regularly. Most of the indium is located on the surface of the solution for easy scooping, but some of the indium is located at the bottom of the solution and floats in the solution, which is not easy to scoop out. More importantly, the collected sponge indium needs to be manually squeezed into a mass to remove residual moisture and obtain an indium product that meets the requirements. In summary, the existing zinc powder replacement method for extracting indium still has complex and difficult operating procedures. The added zinc powder content is difficult to control, which easily affects the purity of sponge indium; the scooping and pressing operations are cumbersome, and it is impossible to scoop out all the sponge indium in the scooping process, and the pressing process will also lose some indium-containing solution, resulting in the loss of indium products; the large amount of heat released in the replacement process will also affect the precipitation of indium. How to achieve the use of zinc powder replacement method to obtain high-quality indium products has become an important issue. Summary of the invention

[0003] The utility model aims to propose an indium replacement tank to solve the problem of how to obtain high-quality indium products by using a zinc powder replacement method in the background technology.

[0004] The technical solution of the utility model is as follows: an indium replacement tank, comprising five tank bodies evenly distributed in an annular shape, wherein a liquid inlet pipe and a liquid outlet pipe are respectively arranged below and above the tank bodies, a liquid inlet branch pipe is connected between the bottom of the tank body and the liquid inlet pipe, a liquid outlet branch pipe is fixed between the top of the tank body and the liquid outlet pipe, an intermediate pipe is arranged between two adjacent tank bodies, the top of the intermediate pipe is connected to the liquid outlet branch pipe on one of the tank bodies, and the bottom of the intermediate pipe is connected to the liquid inlet branch pipe on the other tank body, an external valve 1, an external valve 2, an external valve 3, and an external valve 4 are sequentially installed at the connection between the liquid inlet pipe and the liquid inlet branch pipe and located in the liquid inlet pipe, and an external valve 5, an external valve 6, an external valve 7, and an external valve 8 are sequentially installed at the connection between the liquid outlet pipe and the liquid outlet branch pipe and located in the liquid outlet pipe;

[0005] The five liquid inlet branches are respectively installed with the inner valve 1, the inner valve 2, the inner valve 3, the inner valve 4 and the inner valve 5;

[0006] An internal valve six, an internal valve seven, an internal valve eight, an internal valve nine and an internal valve ten are respectively installed in the five liquid outlet branch pipes.

[0007] Optionally, a water jacket layer 1 is fixed in the liquid outlet branch pipe, a water jacket layer 2 is fixed in the liquid inlet branch pipe, a water jacket layer 3 is fixedly installed on the inner wall of the tank body, the water jacket layer 1, the water jacket layer 2 and the water jacket layer 3 are communicated with each other, a coolant inlet is opened on the water jacket layer 1, and a coolant outlet is opened on the water jacket layer 2.

[0008] Optionally, the inner valve one, the inner valve two, the inner valve three, the inner valve four and the inner valve five are located on one side of the bottom end of the middle tube.

[0009] Optionally, the inner valve six, inner valve seven, inner valve eight, inner valve nine and inner valve ten are located on one side of the top end of the middle tube.

[0012] Optionally, two partitions are installed in the tank body, and the two partitions are respectively located above the feed port and below the discharge port.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] During the replacement process, a large amount of heat generated by the replacement in the tank body and the residual heat of the liquid after the replacement can be taken away. At the same time, part of the secondary heat of the coolant is transferred to the indium-containing solution cooled in the liquid inlet branch pipe, so that the temperature of the liquid before and after the replacement is moderate, which is more conducive to the replacement reaction. At the same time, the influence of the large amount of heat generated by the replacement on the replacement process itself is greatly reduced inside the tank body.

[0015] It is convenient to handle the completely replaced sponge indium inside the tank without affecting the continuous progress of the overall replacement process, thus meeting the needs of industrial production.

[0016] The utility model does not need to consider the impurity of the sponge indium obtained by substitution due to excessive zinc powder, and the loss of sponge indium caused by insufficient manual scooping of sponge indium, and simplifies the manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1-4As shown, the utility model proposes an indium replacement tank, including five annular evenly distributed tank bodies 101, the tank bodies 101 are provided with feed ports and discharge ports 104, and the feed ports and discharge ports 104 are installed with sealing covers by bolts; two partitions 404 are installed in the tank body 101, and the two partitions 404 are respectively located above the feed port and below the discharge port 104, and the feed port is used to add zinc powder, and the sealing cover is opened and closed by screwing the bolts. Before the replacement process begins, the zinc powder added from the feed port is confined between the two partitions 404; because the indium obtained by the zinc powder replacement method is in a relatively fluffy sponge shape, its volume after replacement will increase to a certain extent, but after the replacement process in this embodiment is completed, the indium obtained by replacement is still confined between the fixed upper and lower partitions, which to a certain extent realizes the manual extrusion into agglomerates after the current replacement method of indium extraction, so the utility model greatly simplifies the manual operation.

[0031] like Figure 2-5 As shown, a liquid inlet pipe 102 and a liquid outlet pipe 103 are respectively arranged below and above the tank body 101, a water pump 106 is installed on the liquid inlet pipe 102, a liquid inlet branch pipe 1021 is connected between the bottom of the tank body 101 and the liquid inlet pipe 102, a liquid outlet branch pipe 1031 is fixed between the top of the tank body 101 and the liquid outlet pipe 103, an intermediate pipe 105 is arranged between two adjacent tank bodies 101, and the top of the intermediate pipe 105 is connected to the outlet pipe on one of the tank bodies 101. The bottom of the intermediate tube 105 is connected to the liquid branch pipe 1031, and the bottom and top of each trough body 101 are connected through the liquid inlet pipe 102 and the liquid outlet pipe 103 respectively through the liquid inlet branch pipe 1021 and the liquid outlet branch pipe 1031, and the intermediate tube 105 is connected with the liquid outlet branch pipe 1031 of the previous trough body 101 and the liquid inlet branch pipe 1021 of the next trough body 101 to form a circulation loop.

[0032] like Figure 4 As shown, the connection between the liquid inlet pipe 102 and the liquid inlet branch pipe 1021 and located in the liquid inlet pipe 102 is sequentially installed with an external valve 1 201, an external valve 2 202, an external valve 3 203, and an external valve 4 204, and the connection between the liquid outlet pipe 103 and the liquid outlet branch pipe 1031 and located in the liquid outlet pipe 103 is sequentially installed with an external valve 5 205, an external valve 6 206, an external valve 7 207, and an external valve 8 208;

[0033] Among them, Figure 4As shown, the five liquid inlet branches 1021 are respectively installed with an inner valve 1 301, an inner valve 2 302, an inner valve 303, an inner valve 4 304, and an inner valve 5 305; the inner valve 1 301, the inner valve 2 302, the inner valve 303, the inner valve 4 304, and the inner valve 5 305 are located at one side of the bottom end of the middle tube 105; the five liquid outlet branches 1031 are respectively installed with an inner valve 6 306, an inner valve 7 307, an inner valve 8 308, an inner valve 9 309, and an inner valve 10 310; the inner valve 6 306, the inner valve 7 307, the inner valve 8 308, the inner valve 9 309, and the inner valve 10 310 Eight 308, inner valve nine 309, and inner valve ten 310 are located on one side of the top of the intermediate tube 105; during the replacement process, the indium-containing solution enters from the liquid inlet pipe 102 and the liquid inlet branch pipe 1021 through the water pump 106 and penetrates into each tank body 101 from bottom to top, and fully contacts with the zinc powder added in advance from the feed port of each tank body 101. After the replacement, the liquid and the generated gas are discharged through each liquid outlet branch pipe 1031 and the liquid outlet pipe 103. After the replacement is completed, all the sponge indium obtained by replacement can be directly extracted by negative pressure through the outlet 104 at the lower end of the tank body 101. This technical solution does not need to consider the impurity of the sponge indium obtained by replacement due to excessive zinc powder, and the loss of sponge indium caused by insufficient manual scooping of sponge indium, and simplifies the manual operation.

[0034] like Figure 5-6 As shown, a water jacket layer 1 401 is fixed in the liquid outlet branch pipe 1031, a water jacket layer 2 402 is fixed in the liquid inlet branch pipe 1021, a water jacket layer 3 403 is fixedly installed on the inner wall of the tank body 101, the water jacket layer 1 401, the water jacket layer 2 402, and the water jacket layer 3 403 are communicated with each other, a coolant inlet is opened on the water jacket layer 1 401, and a coolant outlet is opened on the water jacket layer 2 402.

[0035] Furthermore, the coolant is introduced from the coolant inlet provided on the water jacket layer 1 401, and then enters the water jacket layer 3 403, and the coolant is discharged from the coolant outlet provided on the water jacket layer 2 402, and flows from the coolant from top to bottom, which is opposite to the flow direction of the indium-containing solution. During the replacement process, a large amount of heat generated by the replacement in the tank body 101 and the residual heat of the liquid after the replacement can be taken away, and at the same time, part of the secondary heat of the coolant is transferred to the indium-containing solution cooled in the liquid inlet branch 1021, so that the temperature of the liquid before and after the replacement is moderate, which is more conducive to the replacement reaction, and at the same time, the influence of the large amount of heat generated by the replacement on the replacement process itself is greatly reduced inside the tank body 101.

[0036] It is worth noting that during the replacement process, the indium-containing solution is discharged from the bottom of the first tank body 101 through the water pump 106, and then discharged from the top of the second tank body 101 after passing through the intermediate tube 105. After a series of replacement reactions, the replaced liquid is discharged from the outlet pipe branch at the top of the fourth tank body 101 into the outlet pipe 103; after the zinc powder in the first tank body 101 reacts completely, the indium-containing solution is allowed to enter from the bottom of the second tank body 101 and be discharged from the top of the fifth tank body 101, and so on. The advantage of this technology is that it can conveniently handle the completely replaced sponge indium in the tank body 101 without affecting the continuous progress of the overall replacement process, meeting the needs of industrial production.

[0037] Working principle: Zinc powder is added from the feed port, and the coolant is introduced from the coolant inlet provided on the water jacket layer 1 401, and then enters the water jacket layer 3 403, and the coolant is discharged from the coolant outlet provided on the water jacket layer 2 402. The inner valve 1 301 and the inner valve 9 309 are in a closed state, and the outer valve 8 208, the inner valve 2 302, the inner valve 3 303, the inner valve 4 304, the inner valve 6 306, the inner valve 7 307, and the inner valve 8 308 are in an open state. At this time, the indium-containing solution is introduced from the liquid inlet pipe 102 through the water pump 106, passes through the first four tanks 101 from beginning to end, and is discharged from the liquid outlet pipe 103. After the replacement reaction of the first tank body 101 is sufficient, the outer valve 202, the outer valve 8 208, the inner valve 2 302, and the inner valve 10 310 are adjusted to the closed state; the outer valve 1 201, the inner valve 3 303, the inner valve 4 304, the inner valve 5 305, the inner valve 7 307, the inner valve 8 308, and the inner valve 9 309 are adjusted to the open state. At this time, the indium-containing solution enters from the second tank body 101, passes through the fifth tank body from beginning to end, and is discharged from the liquid outlet pipe 103. During this period, the sponge indium can be negatively pressured out at the discharge port 104 of the first tank body 101, and the zinc powder is added again from the feeding port to prepare for the replacement of the second tank body 101 completely, as the next stage of replacement of the tank body 101. By analogy, this embodiment can achieve the requirements of industrial continuous production.
