Description

Technical Field

[0001] The present disclosure relates to the field of electrolysis technology, and in particular to an electrolytic cell with a balanced liquid inlet device. Background Art

[0002] The traditional electrolysis technology is to place the cathode and cathode in a tank where the electrolyte flows slowly. Under the action of the electric field, the anions move toward the anode and the cations move toward the cathode. By controlling certain technical conditions, the target metal cations are electrolytically deposited at the cathode, thereby obtaining a high-purity electrolytic product. Since the electrode reaction rate is often faster than the diffusion rate of the ions, concentration polarization is formed. In the traditional electrolytic cell, it is precisely because of the concentration polarization of the cathode that a small amount of impurity ions or hydrogen ions are precipitated on the cathode together with the target metal ions, which on the one hand leads to a decrease in the quality of the cathode product, and on the other hand, it causes a significant decrease in the cathode current efficiency, thereby increasing the energy consumption per unit product. Therefore, when using traditional electrolysis technology for metal purification or electrolytic deposition, in order to ensure a high cathode current efficiency and cathode product quality, its current density must be controlled within a low range, resulting in a large electrolysis system, high equipment investment costs, and low production efficiency.

[0003] With the development of society and science and technology, and the continuous advancement of metal refining technology, people are pursuing to increase the current density of metal electrolysis, strengthen electrolytic production, and improve the production efficiency of electrolytic cells while ensuring the quality of metals. One of the breakthrough directions is the circulation of electrolyte, increasing the circulation volume of electrolyte, increasing the migration speed of metal ions, and reducing concentration polarization in the electrolytic production process, thereby achieving high current density electrolytic production.

[0004] However, the existing electrolytic cells usually have multiple electrolyte nozzles in the electrolytic cell for liquid inlet, which easily causes uneven liquid flow distribution and uneven electrolyte dispersion. As the electrolyte circulation volume increases, it is easy to cause anode mud agitation, increase the concentration of suspended particles in the electrolyte, and be unfavorable for the sedimentation of the anode mud, seriously affecting the quality of the electrolytic product, such as reducing the recovery rate of precious metals, etc., and the electrolyte nozzle is also prone to clogging, which can easily reduce production efficiency or even clog the electrolyte outlet after long-term production, and has low stability and reliability. Summary of the invention

[0010] In some embodiments, the cathode plate and the anode plate are respectively perpendicular to the balanced liquid inlet device and the liquid guide outlet plate in a vertical direction.

[0011] In some embodiments, the cross-section of the liquid discharge port is rectangular, and the length direction of the liquid discharge port is consistent with the vertical direction.

[0012] In some embodiments, the balanced liquid inlet device includes a liquid inlet box, and the liquid flow channel and the liquid discharge port are arranged on the liquid inlet box.

[0013] In some embodiments, the liquid inlet box is mounted on a panel, and the panel is mounted on the inner wall of the electrolytic cell body.

[0016] In some embodiments, the liquid inlet plate is provided with a first bent edge that matches the inner wall of the electrolytic cell.

[0017] The beneficial effects of the present disclosure are as follows: during use, the external circulating liquid supply system is connected to the liquid flow channel of the balanced liquid inlet device through the corresponding pipeline to supply liquid, and the electrolyte entering the liquid flow channel automatically and evenly enters the interior of the electrolytic cell body from top to bottom through multiple discharge ports, and then flows in parallel between the adjacent cathode plates and anode plates respectively, and is evenly distributed between the cathode plates and anode plates, that is, electrolysis intervals are formed between each adjacent cathode plate and anode plate, and each electrolysis interval does not affect each other, the electrolyte flows stably and single, and turbulence is not easy to occur, and finally the electrolyte enters the diversion liquid outlet channel opposite to the balanced liquid inlet device and then flows out to the external circulating liquid supply system, and stable circulating liquid inlet can be ensured by the balanced liquid inlet device and the diversion liquid outlet channel.

[0031] Example:

[0032] like Figures 1 to 6As shown, an electrolytic cell with a balanced liquid inlet device can be used for electrolysis and electrolytic electrowinning of metals such as copper, zinc, nickel, and manganese, and includes an electrolytic cell body 1 and at least one cathode plate 2 and an anode plate 3. The number of cathode plates 2 and anode plates 3 depends on the specific situation, and is usually a plurality of cathode plates 2 and a plurality of anode plates 3. The cathode plates 2 and the anode plates 3 are sequentially arranged inside the electrolytic cell body 1 at intervals. A balanced liquid inlet device 4 is arranged on the inner wall on one side of the top of the electrolytic cell body 1, and a guide liquid outlet plate 5 is arranged on the inner wall on the other side of the electrolytic cell body 1, that is, the guide liquid outlet plate 5 is located opposite to the balanced liquid inlet device 4, and the cathode plate 2 and the anode plate 3 are located between the balanced liquid inlet device 4 and the guide liquid outlet plate 5. The balanced liquid inlet device 4 is usually arranged horizontally along the length direction inside the electrolytic cell body 1. The length of the balanced liquid inlet device 4 is slightly shorter than the length inside the electrolytic cell body 1 to facilitate installation and other operations. The balanced liquid inlet device 4 has a liquid flow channel 401 and a plurality of discharge ports 402 evenly distributed along the length direction of the liquid flow channel 401. The number and size of the discharge ports 402 depend on the specific situation. The liquid guide plate 5 and the inner wall of the electrolytic cell body 1 form a liquid guide channel 51, that is, the liquid guide channel 51 is located opposite the liquid flow channel 401. The external circulation liquid supply system is connected with the liquid flow channel 401 of the balanced liquid inlet device 4 through the corresponding pipeline for liquid supply. The electrolyte enters the liquid flow channel 401 and enters the interior of the electrolytic cell body 1 through multiple discharge ports 402 in a balanced manner, and then flows in parallel between the adjacent cathode plates 2 and anode plates 3, and is evenly distributed between the cathode plates 2 and anode plates 3, that is, electrolysis intervals are formed between each adjacent cathode plate 2 and anode plate 3, and each electrolysis interval does not affect each other. Finally, the electrolyte enters the diversion liquid outlet channel 51 opposite to the balanced liquid inlet device 4 and then flows out to the external circulation liquid supply system. The electrolyte flows in a stable, single and short direction, and the possibility of flowing in other directions is small. It is not easy to generate turbulence, which improves the utilization rate of the electrolyte. Under the same current density conditions, the required circulation volume is smaller, which reduces the power required to be consumed. Even if the electrolyte circulation volume is increased, the electrolyte in the electrolytic cell body 1 has no turbulence, which is not easy to cause agitation of the anode mud, reduces the concentration of suspended particles in the electrolyte, facilitates the rapid sedimentation of the anode mud, and improves the quality of the electrolysis product.

[0033] The inlet of the diversion liquid outlet channel 51 is located at the bottom of the diversion liquid outlet plate 5, and one end of the top of the electrolytic cell body 1 is provided with a liquid outlet 11 connected to the diversion liquid outlet channel 51. The inlet of the diversion liquid outlet channel 51 is usually roughly flush with the bottom of the cathode plate 2 or the anode plate 3 in the electrolytic cell body 1. The electrolyte enters the interior of the electrolytic cell body 1 from the balanced liquid inlet device 4 on the top side of the electrolytic cell body 1, and then the electrolyte flows in parallel between the adjacent cathode plates 2 and anode plates 3, and is evenly distributed between the cathode plates 2 and anode plates 3. Then the electrolyte enters the diversion liquid outlet channel 51 from the bottom of the diversion liquid outlet plate 5, and finally the electrolyte flows out to the external circulation liquid supply system through the diversion liquid outlet channel 51, that is, the circulation direction of the electrolyte is up-in and down-out, thereby ensuring that the electrolyte interacts more fully and completely with the cathode plate 2 and the anode plate 3, thereby improving the utilization rate and efficiency of the equipment. In addition, the second connecting pipe 6 connecting the external circulating liquid supply system and the balanced liquid inlet device 4 can also be set at one end of the balanced liquid inlet device 4 close to the liquid outlet 11, which makes it easier to connect the electrolytic cell to the external circulating liquid supply system and more convenient to operate.

[0034] A first bent portion 52 is provided at one end of the top of the liquid guiding plate 5 near the liquid outlet 11. The first bent portion 52 and the inner wall of the electrolytic cell body 1 form an outlet of a liquid guiding channel 51 connected to the liquid outlet 11, thereby ensuring that the electrolyte flows out more stably along the liquid guiding channel 51. The liquid guiding plate 5 usually has a second bent edge 53 connected to the inner wall of the electrolytic cell body 1, thereby facilitating the formation of the liquid guiding channel 51 and making the operation more convenient. The electrolytic cell body 1 is provided with a first connecting pipe 12 matched with the liquid outlet 11. The first connecting pipe 12 usually also has a threaded joint, thereby making it easier to connect to an external circulating liquid supply system and making the operation more convenient.

[0035] The diversion outlet plate 5 is provided with a plurality of partitions 54 along the vertical direction. The partitions 54 are located in the diversion outlet channel 51. The partitions 54 are arranged in sequence along the length direction of the diversion outlet plate 5. The top of the partition 54 is substantially flush with the bottom of the first bending portion 52, that is, the top of the partition 54 is substantially flush with the bottom of the outlet of the diversion outlet channel 51, thereby dividing the diversion outlet channel 51 into a plurality of channels. The electrolytes in different electrolysis intervals respectively enter different channels in the diversion outlet channel 51, thereby reducing mutual interference, being less likely to generate turbulence, and being more stable and reliable.

[0036] The cathode plate 2 and the anode plate 3 are respectively perpendicular to the balanced liquid inlet device 4 and the diversion liquid outlet plate 5 in the vertical direction, so that the electrolyte flows in parallel between the cathode plate 2 and the anode plate 3, and the flow direction of the electrolyte is respectively parallel to the cathode plate 2 and the anode plate 3, so that the electrolyte is more evenly distributed between the cathode plate 2 and the anode plate 3, reducing the flow of the electrolyte in other directions, without generating turbulence, and not easily causing agitation of the anode mud, so as to facilitate rapid sedimentation of the anode mud, and have higher stability and reliability.

[0037] The cross section of the drain port 402 is rectangular, the length direction of the drain port 402 is consistent with the vertical direction, the bottom of the drain port 402 is usually higher than the bottom of the liquid flow channel 401, and after the electrolyte enters the liquid flow channel 401, when the liquid level exceeds the bottom of the drain port 402, the electrolyte automatically and stably enters the interior of the electrolytic cell body 1 through the rectangular drain port 402. If the drain port 402 adopts other shapes such as V-shaped, the liquid inlet stability is relatively poor. In addition, the top of the liquid flow channel 401 and the top of the diversion and outlet channel 51 can be open or closed by corresponding cover plates.

[0038] like Figure 4 As shown, the first scheme of the balanced liquid inlet device 4, the balanced liquid inlet device 4 includes a liquid inlet box 41, a liquid flow channel 401 and a liquid discharge port 402 are arranged on the liquid inlet box 41, the liquid inlet box 41 can be directly fixed on the inner wall of the electrolytic cell body 1, the liquid inlet box 41 can also be installed on a panel 42, the panel 42 is installed on the inner wall of the electrolytic cell body 1, and the inner wall of the electrolytic cell body 1 can also be provided with a first trough 13 for placing the panel 42, which is convenient to operate and has a more stable and reliable structure. In addition, a mounting block 16 for fixing the liquid inlet box 41, such as a resin block, can be arranged on the inner wall of the electrolytic cell body 1, and the liquid inlet box 41 can also be provided with a reinforcing rib 411, so that when the liquid inlet box 41 is relatively long, the structural strength of the liquid inlet box 41 can also be ensured, which is more stable and reliable.

[0039] like Figure 5 As shown, the second scheme of the balanced liquid inlet device 4, the balanced liquid inlet device 4 includes a liquid inlet plate 43, the liquid inlet plate 43 and the inner wall of the electrolytic cell body 1 form a liquid flow channel 401, the liquid discharge port 402 is arranged on the liquid inlet plate 43, and the liquid inlet plate 43 can be fixed to the inner wall of the electrolytic cell body 1 by gluing, fastener connection, etc., the structure is simpler, more compact, and the operation is more convenient. The liquid inlet plate 43 is usually provided with a first bent edge 431 connected to the inner wall of the electrolytic cell body 1, so as to facilitate the formation of the liquid flow channel 401, and the operation is more convenient.

[0040] A sewage outlet 15 is also provided at the bottom of the electrolytic cell body 1 to facilitate the regular discharge of anode mud deposited in the electrolytic cell body 1, thereby improving the efficiency of electrolysis and making it more stable and reliable.

[0041] The outer side and the outer bottom of the electrolytic cell body 1 may also be provided with a plurality of supporting protrusions 14 , respectively. The number and position distribution of the supporting protrusions 14 are determined according to specific circumstances, so as to facilitate more stable placement of the electrolytic cell body 1 .

[0042] During use, the external circulation liquid supply system circulates and supplies liquid. The external circulation liquid supply system is connected to the liquid flow channel 401 of the balanced liquid inlet device 4 through the corresponding pipeline to supply liquid. The electrolyte entering the liquid flow channel 401 enters the interior of the electrolytic cell body 1 through multiple discharge ports 402. The rectangular discharge ports 402 facilitate the electrolyte to automatically and evenly enter the interior of the electrolytic cell body 1 from top to bottom, and then flow in parallel between the adjacent cathode plates 2 and anode plates 3, and are evenly distributed between the cathode plates 2 and anode plates 3, that is, each adjacent cathode plate 2 and anode plate 3 form an electrolysis interval, each electrolysis interval does not affect each other, the electrolyte flows stably and single, and turbulence is not easy to occur, and then the electrolyte enters the diversion outlet channel 51 from the bottom of the diversion outlet plate 5, and finally the electrolyte enters the diversion outlet channel 51 opposite the balanced liquid inlet device 4 and then flows out from the outlet 13 to the external circulation liquid supply system. Compared with the prior art, the present invention can ensure stable circulation of liquid inflow through the balanced liquid inlet device 4 and the diversion liquid outlet channel 51. The electrolyte enters the balanced liquid inlet device 4 and then exits the diversion liquid outlet channel 51 opposite to the balanced liquid inlet device 4, so that the electrolyte flow is the shortest, the electrolyte flow direction is stable and single, and the possibility of flowing in other directions is small, thereby improving the utilization rate of the electrolyte. Under the same current density conditions, the required circulation volume is smaller, and the required power consumption is reduced. Even if the electrolyte circulation volume is increased, the electrolyte in the electrolytic cell body 1 has no turbulence, and it is not easy to cause agitation of the anode mud. The concentration of suspended particles in the electrolyte is reduced, which is convenient for the rapid sedimentation of the anode mud, and the quality of the electrolytic product is improved. For example, the silver content in the cathode copper is reduced, and the recovery rate of precious metals is improved. In addition, the electrolyte nozzle is eliminated, and the electrolyte nozzle will not be easily blocked. After a long period of production, it is not easy to block the electrolyte outlet, and the production efficiency is high, and the stability and reliability are high.

[0043] The above are only some embodiments of the present disclosure, which are only used to illustrate the technical solution of the present disclosure, rather than to limit it. It should be understood that, for those skilled in the art, without departing from the creative concept of the present disclosure, it is possible to make improvements or substitutions according to the above description, and all these improvements and substitutions should fall within the scope of protection of the claims attached to the present disclosure. In this case, all details can be replaced by equivalent elements, and the materials, shapes and sizes can also be arbitrary.
