The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only used as examples and cannot be used to limit the scope of protection of the present application.

[0019] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the long-process germanium extraction device provided in the embodiment of the present application. Figure 2A schematic diagram of the local structure of the extraction component provided in the embodiment of the present application. The long-process germanium extraction device 100 includes a placement rack 110 and an extractant storage tank 120. The placement rack 110 is used to fix the extraction component 130. Usually, the placement rack 110 is a double-layer structure connected by rods. The upper layer is used to fix the mixing box 131 and the buffer box 133, and the lower layer is used to fix the stratification tank 132, so that there is a certain layer height between the stratification tank 132 and the mixing box 131, thereby ensuring that the extractant and the stock solution in the mixing box 131 can fall into the stratification tank 132 under their own gravity after mixing. The extractant storage tank is used to store the extractant. Multiple groups of extraction components 130 are connected in series on the placement rack 110 in sequence, and the multiple groups of extraction components 130 perform multi-stage extraction on the stock solution to ensure the extraction effect. The extraction component 130 includes a mixing box 131, a stratification tank 132 and a buffer box 133. The buffer box 133 is used to temporarily store the raw liquid. The raw liquid in the head end buffer box 133 is pumped to the mixing box 131 by setting a corresponding pump body, and the extractant in the extractant storage tank is also pumped to the mixing box 131 by a corresponding conveying device. A stirring device 134 is provided in the inner cavity of the mixing box 131. The stirring device 134 is used to stir the solution in the mixing box 131, thereby accelerating the mixing of the solution and further accelerating the extraction process. The bottom of the mixing box 131 is connected with a discharge pipe 131a, and there are two stratification tanks 132. The two stratification tanks 132 are symmetrically arranged on both sides of the bottom of the mixing box 131. The discharge pipe 131a is connected with a first feed pipe 131c and a second feed pipe 131d through a three-way valve 131b. The first feed pipe 131c and the second feed pipe 131d extend into the two stratification tanks 132 respectively. When the solution is fully stirred in the mixing box 131, the corresponding three-way valve 131b is controlled so that the solution in the mixing box 131 is divided into batches and sequentially enters one of the two stratification tanks 132 through the first feed pipe 131c or the second feed pipe 131d, and is statically stratified in the stratification tank 132. At this time, since the other stratification tank 132 is in an empty state, the mixing box can work again and transport the remixed solution to the empty stratification tank 132 for static stratification. In this way, the two stratification tanks 132 alternately receive the solution from the buffer tank. The bottom of the stratification tank 132 is connected with a first liquid outlet 132a and a second liquid outlet 132b. The first liquid outlet 132a is connected with a finished product storage tank. The solution will be stratified after standing for a period of time in the stratification tank 132. After the stratification is completed, the two layers of solution are respectively discharged through the first liquid outlet 132a and the second liquid outlet 132b. The finished solution is introduced into the finished product storage tank for storage, and the solution in the mixed layer still contains more germanium, so it is discharged through the second liquid outlet 132b to the next extraction component 130 for the next level of extraction.The second liquid outlets 132b and the buffer box 133 on two adjacent extraction components 130 are connected in sequence. Here, a conventional device such as a pump body should be provided on the buffer box 133, so that the mixed liquid at the second liquid outlet 132b can be pumped into the buffer box 133. Through the above arrangement, the germanium-containing mixed liquid of the previous stage enters the buffer box 133 of the next stage through the connection between the second liquid outlet 132b and the buffer box 133, so that the extraction work continues at the next stage. The extractant storage tank 120 is connected to the multiple mixing boxes 131 through the conveying device, and the extractant storage tank 120 can supply the extractant to the multiple mixing boxes 131.
[0020] As can be seen from the above, in the embodiment of the present application, by setting multiple groups of extraction components 130 in series, and connecting the second liquid outlet 132b and the buffer box 133 on two adjacent extraction components 130, the germanium-containing raw liquid or the germanium-containing mixed liquid can be sequentially extracted by multiple extraction components 130, thereby ensuring the extraction efficiency during the extraction process and reducing the content of germanium in the residual liquid. By setting two stratification tanks 132, the two stratification tanks 132 are used alternately, and the two stratification tanks 132 alternately receive the mixed liquid from the mixing box, thereby providing sufficient time for the static stratification process of the raw liquid, thereby ensuring the stratification effect, further improving the extraction effect of germanium, and reducing the content of germanium in the residual liquid. On the other hand, due to the two stratification tanks 132, the mixing box can operate continuously, and the mixed liquid is alternately injected into the two stratification tanks 132, and then the mixing box 131 does not stop during the static stratification process of one of the stratification tanks 132, thereby improving the extraction speed.
[0021] In some embodiments, the tops of the two stratified tanks 132 are both provided with safety airbags 132c, and the safety airbags 132c are connected to the stratified tanks 132 through electromagnetic safety valves 132d. In the embodiment of the present application, through the above arrangement, when the stratified tanks 132 are being filled and drained, the electromagnetic safety valves 132d are opened, and the gas in the safety airbags 132c can balance the air pressure in the stratified tanks 132, which makes the process of draining and filling more efficient on the one hand, and prevents the solution from being dispersed in the air after being vaporized.
[0022] In some embodiments, a PLC control box is included, the three-way valve 131b is an electromagnetic three-way valve 131b, and the electromagnetic three-way valve 131b and the electromagnetic safety valve 132d are both electrically connected to the PLC control box. In the embodiment of the present application, through the above settings, the electromagnetic three-way valve 131b and the electromagnetic safety valve 132d can be controlled by the PLC control box, further improving the degree of automation in the production process of the present application and reducing labor costs.
[0023] In some embodiments, a temporary extractant storage tank 135 is included, and there are multiple temporary extractant storage tanks 135. The multiple temporary extractant storage tanks 135 are respectively connected to the multiple mixing boxes 131 through a conveying device, and the extractant storage tank 120 is respectively connected to the multiple temporary extractant storage tanks 135 through a water pump and a pipeline. In the embodiment of the present application, through the above-mentioned setting, each mixing box 131 is equipped with an extractant temporary storage tank 135, and each mixing box 131 can directly extract the extractant through the temporary extractant storage tank 135, thereby improving the independent performance of each extraction component 130. In some embodiments, the stirring device 134 includes a rotating sleeve 134a connected to the inner cavity of the mixing box through a thin rod, and a rotating shaft 134b is rotatably connected to the rotating sleeve 134a. The other end of the rotating shaft 134b extends upward to the top of the mixing box 131 and is transmission-connected to a stirring motor 134c, and a stirring blade 134d is connected to the rotating shaft 134b. The embodiment of the present application provides a specific setting method of the stirring device 134. During operation, the stirring motor 134c drives the rotating shaft 134b and the stirring blades 134d to rotate, thereby stirring the solution in the mixing box 131 to accelerate the fusion between the solutions.
[0024] In some embodiments, the cross-section of the stratified tank 132 is a regular hexagonal shape, and the placement rack 110 forms two inclined support blocks, which abut and support the outer periphery of the stratified tank 132. The stratified tank 132 is made of transparent material, and scale bars 132e are vertically distributed on the stratified tank 132.
[0025] In the embodiment of the present application, through the above settings, the stratification tank 132 is set to a transparent material, so as to facilitate observation of the stratification situation in the stratification tank 132. The regular hexagonal shape of the stratification tank 132 and the setting of the support block make the installation of the stratification tank 132 more stable, and no fixed connection is required, and disassembly is more convenient.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
