[0039] As described in the background, in the existing nickel electrodeposition anode bag production mode, the nickel sulfate electrolyte is transported to the bottom of the electrodeposition tank through the cathode liquid pipe, the uniformly distributed liquid inlet hole introduces it into the tank, and then the electrodeposition process is carried out. However, this electrodeposition method needs to be perforated on the wall of the electrodeposition tank, and pipes are arranged on the outer wall of the electrodeposition tank, which causes the electrodeposition tank to be arranged in pairs in the factory building, resulting in large floor area, low space utilization rate and increased production cost.

[0040] Based on this, please refer to Figures 1-4 The embodiment of the utility model provides an electrodeposition nickel anode bag electrodeposition tank 100 and production equipment, which can effectively improve the above-mentioned technical problems, that is, it can reduce the floor area, improve the space utilization rate and reduce the production cost. The electrodeposition nickel anode bag electrodeposition tank 100 and production equipment will be described in detail below.

[0041] Please refer to Figure 1 , Figure 1 The structure diagram of the electrodeposition nickel anode bag production equipment 1000 provided in the embodiment, combined with Figure 1, the electro-deposition nickel anode bag production equipment 1000 comprises an electro-deposition nickel anode bag electro-deposition tank 100, a cathode liquid supply device 200 and an anode liquid and acid mist collecting device 300. The cathode liquid supply device 200 is communicated with the electro-deposition nickel anode bag electro-deposition tank 100, and is used for supplying the cathode liquid into the electro-deposition nickel anode bag electro-deposition tank 100. The anode liquid and acid mist collecting device 300 is communicated with the electro-deposition nickel anode bag electro-deposition tank 100, and is used for recycling the anode liquid formed by the electro-deposition in the electro-deposition nickel anode bag electro-deposition tank 100 and returning to the subsequent refining process; meanwhile, the anode liquid and acid mist collecting device 300 is also used for recycling and processing the acid gas formed in the electro-deposition tank, so as to realize the standard emission.

[0042] Specifically, refer to Figure 2 and Figure 3 , Figure 2 the first view structural schematic diagram of the electro-deposition nickel anode bag electro-deposition tank 100 provided in the embodiment, Figure 3 the second view structural schematic diagram of the electro-deposition nickel anode bag electro-deposition tank 100 provided in the embodiment.

[0043] Combined with Figure 2 and Figure 3 , the electro-deposition nickel anode bag electro-deposition tank 100 comprises a tank body 10, a liquid inlet unit 20 and a liquid outlet and acid mist collecting unit 30. The liquid inlet unit 20 comprises a cathode liquid inlet main pipe 21 and a plurality of cathode liquid inlet branch pipes 22. The cathode liquid inlet main pipe 21 is communicated with the plurality of cathode liquid inlet branch pipes 22 simultaneously. The plurality of cathode liquid inlet branch pipes 22 are arranged in the tank body 10 at intervals. A part of the cathode liquid inlet main pipe 21 is arranged in the tank body 10, and both ends of the cathode liquid inlet main pipe 21 extend out of the tank surface of the tank body 10. The liquid outlet and acid mist collecting unit 30 comprises an anode liquid outlet main pipe 31 (which has the function of collecting the gas and acid mist generated by the anode) and a plurality of anode liquid outlet branch pipes 32. The anode liquid outlet main pipe 31 is communicated with the plurality of anode liquid outlet branch pipes 32 simultaneously. The plurality of anode liquid outlet branch pipes 32 are arranged in the tank body 10 at intervals. A part of the anode liquid outlet main pipe 31 is arranged in the tank body 10, and the liquid outlet end 311 of the anode liquid outlet main pipe 31 extends out of the tank surface of the tank body 10.

[0044] That is to say, most of the pipelines in the electro-deposition tank are arranged in the tank body 10. Only the inlet part of the cathode liquid inlet main pipe 21 and the outlet part of the anode liquid outlet main pipe 31 extend out of the tank surface and are connected with other devices of the electro-deposition nickel production equipment. Combined with Figures 1-3 , specifically in the embodiment, the cathode liquid supply device 200 is communicated with both ends of the cathode liquid inlet main pipe 21 simultaneously, so as to realize the circulation of the cathode liquid and the uniform liquid inlet into the tank body 10. The anode liquid and acid mist collecting device 300 is communicated with the liquid outlet end 311 of the anode liquid outlet main pipe 31, so as to process the anode liquid and the acid gas.

[0045] It is easy to understand that the nickel electrowinning anode bagged electrowinning tank 100 provided by the embodiment can fix the pipeline on the tank surface when producing nickel electrowinning, compared with the prior art of opening a large number of holes in the tank wall and arranging pipelines outside the electrowinning tank. The manufacturing difficulty is reduced, the use area of the parallel arrangement of the electrowinning tank is improved, the overall equipment area is reduced, the multiple electrowinning tanks are arranged in series, the arrangement number of the electrowinning tank is improved, and the space utilization is improved. And by the way of liquid inlet at both ends of the cathode liquid inlet main pipe 21 and liquid distribution through the plurality of cathode liquid inlet branch pipes 22, the pressure of each cathode liquid inlet branch pipe 22 is basically the same, so that the effect of simple maintenance and cost reduction is realized.

[0046] It should be noted that in the embodiment, the cathode liquid inlet main pipe 21 is provided with liquid inlet ends 211 at both ends, and the two liquid inlet ends 211 are arranged opposite to each other from the tank surface of the tank body 10. By arranging the two liquid inlet ends 211 opposite to each other, the cathode liquid can be introduced into the tank body 10 from both sides, and the cathode liquid can be uniformly distributed through the plurality of cathode liquid inlet branch pipes 22, thereby improving the subsequent electrowinning effect. Of course, in other embodiments, the two liquid inlet ends 211 can be arranged adjacent to each other.

[0047] Please continue to combine Figures 1-3 Specifically, the cathode liquid supply device 200 includes a cathode liquid supply box 201 and a cathode liquid circulating pump 202 in communication, the cathode liquid supply box 201 is in communication with one end of the cathode liquid inlet main pipe 21, and the cathode liquid circulating pump 202 is in communication with the other end of the cathode liquid inlet main pipe 21.

[0048] It can be understood that the cathode liquid supply box 201 can continuously supply cathode liquid into the tank body 10, and the cathode liquid circulating pump 202 can realize the recycling of the cathode liquid. According to the actual electrowinning process, the delivery amount and delivery rate of the cathode liquid can be controlled in real time, which is convenient to operate and improves the electrowinning effect.

[0049] Further, the anode liquid and acid mist collecting device 300 includes a gas-liquid separator 301, an anode liquid transfer pump 302, a vacuum pump 303, and a tail gas recovery device 304. The gas-liquid separator 301 is in communication with the liquid outlet end 311 of the anode liquid outlet main pipe 31, the anode liquid transfer pump 302 and the vacuum pump 303 are in communication with the gas-liquid separator 301, and the tail gas recovery device 304 is in communication with the vacuum pump 303.

[0050] It can be understood that the gas-liquid separator 301 can separate the anolyte and the acid gas formed in the tank body 10, so that the anolyte after separation can be transported by the anolyte circulating pump 302 and returned to the subsequent refining process; and the acid gas after separation can be extracted by the vacuum pump 303 and transported to the tail gas recovery device 304 for treatment.

[0051] Specifically, the tail gas recovery device 304 includes a tail gas recovery tower 3041, an absorption liquid supply tank 3042, and an absorption liquid circulating pump 3043, which are sequentially connected in series. The absorption liquid supply tank 3042 is in communication with the vacuum pump 303.

[0052] It can be understood that the absorption liquid supply tank 3042 can provide absorption liquid, which can react with the acid gas. The reaction product is discharged through the tail gas recovery tower 3041, and the absorption liquid circulating pump 3043 can circulate the absorption liquid in the pipeline of the tail gas recovery device 304, thereby improving the efficiency and effect of tail gas treatment.

[0053] Please continue to combine Figure 1 The electrowinning nickel anode bag production equipment 1000 further includes a filter 400, the cathode liquid supply device 200, the filter 400, and the cathode liquid inlet main pipe 21 are sequentially connected. By setting the filter 400, the cathode liquid can be filtered in advance, thereby improving the subsequent electrowinning effect in the tank body 10.

[0054] Please continue to combine Figure 2 and Figure 3 The electrowinning nickel anode bag production equipment 1000 further includes a filter 400, the cathode liquid supply device 200, the filter 400, and the cathode liquid inlet main pipe 21 are sequentially connected. By setting the filter 400, the cathode liquid can be filtered in advance, thereby improving the subsequent electrowinning effect in the tank body 10.

[0055] Combine Figures 1-3That is, the cathode liquid supply device 200 inputs the cathode liquid from both ends of the cathode liquid inlet main pipe 21, then distributes the cathode liquid through the plurality of cathode liquid inlet branch pipes 22, and delivers the cathode liquid to the bottom of the corresponding cathode plate 40 in the tank body 10, and then the cathode liquid flows uniformly in the tank body 10 from bottom to top, so that the concentration of the electrodeposition liquid in the entire tank body 10 is basically consistent, and the process of supplementing the cathode liquid is realized. After the electrodeposition is completed, the electrodeposition liquid forms an anode liquid and an acidic gas under the action of the concentration difference and the electric field through the anode sleeve bag assembly 50, and then the anode liquid and the acidic gas are converged to the anode liquid outlet main pipe 31 through the plurality of anode liquid outlet branch pipes 32, and then under the action of the vacuum pump 303 and the anode liquid transfer pump 302, the anode liquid and the acidic gas are separated in the gas-liquid separator 301 and then enter different processes for treatment.

[0056] It should be noted that by arranging the plurality of cathode plates 40 to correspond to the plurality of cathode liquid inlet branch pipes 22 one by one, that is, each cathode liquid inlet branch pipe 22 corresponds to one cathode plate 40, each cathode liquid inlet branch pipe 22 can be individually disassembled and controlled, thereby further facilitating maintenance and reducing use costs, and the number of cathode plates 40 can also be conveniently controlled.

[0057] Specifically, referring to Figure 4 , Figure 4 The structure diagram of the anode sleeve bag assembly 50 provided for the embodiment, in combination with Figures 2-4 , the anode sleeve bag assembly 50 includes an anode plate 51, an inner framework 52, and a diaphragm bag 53, the anode plate 51 is arranged in the inner framework 52, the diaphragm bag 53 is wrapped around the inner framework 52 and the anode plate 51 and forms a closed cavity 54, and the anode liquid outlet branch pipe 32 is in communication with the closed cavity 54.

[0058] That is, after the electrodeposition is completed, the electrodeposition liquid penetrates from the cathode area to the closed cavity 54 through the diaphragm bag 53 due to the concentration relationship and the action of the cathode and anode electric field, forming an anode liquid; and during the entire electrodeposition process, the acidic gas is confined in the closed cavity 54 in the diaphragm bag 53, and then under the action of the vacuum pump 303, the acidic gas can be sequentially extracted from the anode liquid outlet branch pipe 32 and the anode liquid outlet main pipe 31, and then subjected to gas-liquid separation in the gas-liquid separator 301.

[0059] Please refer to Figure 3 Specifically, the cathode liquid inlet branch pipe 22 includes a first liquid inlet branch pipe 221 and a second liquid inlet branch pipe 222, the cathode liquid inlet main pipe 21, the first liquid inlet branch pipe 221, and the second liquid inlet branch pipe 222 are sequentially in communication, the first liquid inlet branch pipe 221 is arranged to extend along the length direction of the cathode plate 40, and the second liquid inlet branch pipe 222 is arranged to extend along the width direction of the cathode plate 40.

[0060] It should be noted that the length direction mentioned in the above content is the A direction shown in Figure 3 the width direction is the B direction shown in Figure 3 It is easy to understand that the cathode liquid inlet branch pipe 22 as a whole is a pipe similar to "L" shape, through this setting, the catholyte can be delivered to the bottom of the tank body 10, and uniformly released at the bottom of the cathode plate 40, thereby improving the subsequent electrodeposition effect.

[0061] Further, in order to protect the cathode liquid inlet branch pipe 22, in the embodiment, the electrodeposited nickel anode sleeve bag electrodeposition tank 100 further comprises a support frame 60 and a protection plate 70, the support frame 60 is arranged on the bottom wall of the tank body 10, the protection plate 70 is arranged on the support frame 60, and is arranged in the bottom of the cathode plate 40. The second liquid inlet branch pipe 222 is arranged on the side of the protection plate 70 away from the cathode plate 40. By arranging the protection plate 70 between the second liquid inlet branch pipe 222 and the cathode plate 40, the second liquid inlet branch pipe 222 can be protected, and the cathode plate 40 can be prevented from falling and damaging the second liquid inlet branch pipe 222. In addition, even if the cathode plate 40 falls, it will fall on the protection plate 70, so that the fallen cathode plate 40 can be easily picked up.

[0062] Please continue to combine Figure 2 , the anode liquid outlet main pipe 31 comprises a first liquid outlet main pipe 312 and a second liquid outlet main pipe 313, the first liquid outlet main pipe 312 is arranged in the tank body 10 and communicates with a plurality of anode liquid outlet branch pipes 32; a part of the second liquid outlet main pipe 313 is arranged in the tank body 10, and the other part extends out of the tank surface of the tank body 10; wherein the height of the first liquid outlet main pipe 312 gradually decreases along the direction close to the second liquid outlet main pipe 313.

[0063] That is, the first liquid outlet main pipe 312 can be understood as being arranged downwardly inclined towards the direction close to the second liquid outlet main pipe 313, so that the anolyte in each anode liquid outlet branch pipe 32 can flow into the second liquid outlet main pipe 313 under the action of gravity, thereby the power of the vacuum pump 303 or the anolyte transfer pump 302 does not need to be too high, thereby saving energy consumption and reducing procurement cost and use cost.

[0064] Since the anode liquid and the acid gas exist in the anode liquid outlet main pipe 31, in order to ensure that the anode liquid can be sucked out by the negative pressure before the acid gas, in the embodiment, the anode liquid outlet main pipe 31 further comprises a liquid outlet elbow 314, the liquid outlet elbow 314 is arranged in the tank body 10, the first liquid outlet main pipe 312, the liquid outlet elbow 314 and the second liquid outlet main pipe 313 are sequentially communicated, and the height of the liquid outlet elbow 314 is lower than the height of the first liquid outlet main pipe 312. By arranging the liquid outlet elbow 314, the liquid outlet elbow 314 can play a role of a liquid accumulation channel. If the liquid exists, the liquid will gather into a liquid seal at the liquid outlet elbow 314, so that the principle of liquid extraction and gas extraction is realized. That is, under the action of the negative pressure, the anode liquid flowing to the liquid outlet elbow 314 can be first sucked out, and then the acid gas is sucked out through the anode liquid outlet main pipe 31 and the anode liquid outlet branch pipe to the solution-free area.
