Description

Technical Field

[0001] The present invention relates to the technical field of electrolysis equipment, and in particular to a metal ion electrolysis recovery device and a material recovery production line thereof. Background Art

[0002] In the field of metal recycling, a common approach is to use chemicals to leach the metal, then reduce the metal ions in the chemicals to elemental metal through chemical reactions. For example, in the case of silver recycling, a common method involves dissolving the silver in nitric acid and then reducing the silver ions to elemental silver through electrolysis.

[0003] However, existing electrolysis devices have significant defects in actual factory production, especially in continuous production scenarios. First, traditional electrolytic cells mostly use intermittent liquid supply and drainage modes, which leads to frequent start and stop during the electrolysis process, making it difficult to achieve dynamic matching of material transportation and electrolysis reaction, which seriously restricts the processing efficiency; second, in some existing electrolysis devices that can work continuously, in order to improve the electrolysis rate and the recovery rate of materials, the unreacted reaction liquid is usually refluxed and re-electrolyzed, that is, it is usually equipped with a corresponding reflux system. However, on the one hand, the setting of the reflux system increases the overall construction cost and operating cost of the recovery equipment; on the other hand, the dynamic matching between the operating rhythm of the complex processing equipment in the reflux system and the operating rhythm of the electrolysis device greatly increases the difficulty of the overall operation coordination of the recovery equipment, which is not conducive to the user's operation.

[0004] Therefore, there is an urgent need for an electrolysis device that can carry out electrolysis work continuously and efficiently and is easy to operate to meet the needs of fast-paced production line processing. Summary of the Invention

[0005] The present invention provides a metal ion electrolysis recovery device with a streamlined overall structure. While ensuring the recovery rate of metal materials, it can continuously carry out electrolysis work and achieve efficient recovery of metal materials.

[0006] The present invention is achieved through the following technical solutions: A metal ion electrolysis recovery device comprises: a liquid storage portion for storing a liquid phase, wherein the liquid storage portion is divided into a reaction liquid storage portion and a reuse liquid storage portion by a separation membrane, wherein the reaction liquid storage portion is used to store a reaction liquid, wherein the reaction liquid contains at least metal ions and components of the reuse liquid, and the separation membrane allows the components of the reuse liquid to pass through and be stored in the reuse liquid storage portion; an electrolysis portion, comprising a plurality of electrolysis units, each of which comprises an infusion port, a discharge port, an anode, and a cathode. The electrode; the pipeline connection part includes several groups of delivery pumps and several groups of connecting pipelines for connecting various components and driving the liquid phase to flow. The delivery pumps and the connecting pipelines are combined to form a receiving working part, an electrolysis working part and a recycling working part. The receiving working part is connected to the reaction liquid storage part to drive the external reaction liquid to enter. The infusion port and the discharge port are both connected to the reaction liquid storage part through the electrolysis working part. The recycling working part is connected to the recycled liquid storage part to drive the recycled liquid to flow outward.

[0007] As a further improvement of the present invention, the electrolysis unit includes an electrolysis barrel, the anode arranged in the electrolysis barrel, and the cylindrical cathode, the cathode divides the space in the electrolysis barrel into a reaction zone and an external discharge zone, the anode is placed in the reaction zone, the infusion port is connected to the reaction zone, the discharge port is connected to the external discharge zone, and an overflow portion is provided on the top of the cathode so that the liquid phase flows into the external discharge zone through the overflow portion after the electrolysis is completed in the reaction zone.

[0008] As a further improvement of the present invention, the cathode is movably installed in the electrolysis barrel through a first quick-release structure.

[0009] As a further improvement of the present invention, the first quick-release structure includes a positioning groove arranged on the inner bottom surface of the electrolytic barrel and a locking structure arranged at the top edge of the electrolytic barrel, wherein the locking structure includes an elastic fitting kit. When the first quick-release structure completes the installation and fixation of the cathode, one end of the elastic fitting kit is in contact with the cathode and the other end is connected to the power supply to connect the cathode and the power supply.

[0010] As a further improvement of the present invention, the overflow portion includes a plurality of overflow holes.

[0011] As a further improvement of the present invention, the anode is movably installed in the electrolysis barrel through a second quick-release structure.

[0012] As a further improvement of the present invention, the second quick-release structure includes a threaded fastening kit arranged at the bottom of the anode.

[0013] As a further improvement of the present invention, the electrolysis unit also includes a guide sleeve arranged in the reaction zone, and the infusion port is arranged at the bottom of the reaction zone. The liquid phase entering the reaction zone is guided by the guide sleeve, contacts the cathode and flows to the location of the overflow part.

[0014] As a further improvement of the present invention, it further comprises an exhaust portion disposed above the electrolysis portion for exhausting the gas phase generated by the reaction in the electrolysis portion.

[0015] In a second aspect, the present invention provides a material recovery production line comprising any of the above-mentioned metal ion electrolysis recovery equipment.

[0016] The beneficial effects of the present invention include: (1) The reaction liquid entering the reaction liquid storage part usually includes metal ions and a liquid phase that does not participate in the reaction, wherein the liquid phase that does not participate in the reaction has the same composition as the recycled liquid obtained by subsequent processing. The electrolysis working part can drive the reaction liquid into the electrolysis part for electrolysis reaction, during which the metal material can be reduced and separated from the reaction liquid, and the remaining components in the reaction liquid will also be converted into recycled liquid to be reused for the dissolution of the metal material; in the present invention, the electrolysis working part will return the recycled liquid obtained by the reaction and the unelectrolyzed reaction liquid to the reaction liquid storage part, and the separation in the liquid storage part The diaphragm can only allow the components of the reused liquid to pass through. On the one hand, this allows the metal ions that were not reduced in the previous electrolysis reaction to be retained in the reaction liquid storage part, and then to participate in the electrolysis reaction again, thereby improving the recovery rate of the metal material. On the other hand, under the structure of the present invention, when the electrolysis recovery equipment is in operation, the transmission paths of various liquid phases are shorter, and the number of equipment and devices that constitute the reflux system is smaller, which greatly reduces the manufacturing cost of the electrolysis recovery equipment and ensures that the reflux work can be carried out quickly and adapted to the continuous working rhythm, so that the overall operation efficiency of the electrolysis recovery equipment is faster.

[0017] (2) After the separation membrane separates the liquid storage part, the components of the recycled liquid in the reaction liquid can smoothly enter the recycled liquid storage part. During this period, the recycled working part pumps the recycled liquid outward to provide power for the movement of the components of the recycled liquid. Taking the electrolytic recovery equipment of the present invention for the electrolytic treatment of silver nitrate as an example, under the above-mentioned power drive, a large amount of nitrate and hydrogen ions in the reaction liquid storage part enter the recycled liquid storage part, and ensure that the concentration relationship between silver ions and nitrate ions in the reaction liquid storage part and the electrolysis part is always close to 1:1. In particular, in the actual industrial production process, the reaction liquid usually contains a large amount of nitric acid that does not participate in the reaction, that is, the content of nitrate ions in the reaction liquid is much greater than the content of silver ions. Under the structural arrangement of the present invention, the occurrence of situations such as the difficulty in efficiently carrying out the electrolytic reaction due to the nitrate content being too high relative to the silver ion content is avoided, and the efficiency of the metal ion electrolytic reaction is greatly improved, which meets the requirements of efficient work.

[0018] (3) Under the preferred structure, the cathode and anode are installed in the electrolytic barrel through the first quick-release structure and the second quick-release structure respectively. This greatly simplifies the disassembly and installation process of the cathode and anode, allowing users to quickly complete the replacement or cleaning of the electrodes, greatly shortening the downtime during maintenance and repair, ensuring the continuous operation of the electrolytic recovery equipment, and thus adapting to the needs of efficient industrial production.

[0019] (4) Under the preferred structure, the first quick-release structure includes an elastic fitting kit, which has the ability to conduct electricity. At the same time, after the cathode is frequently disassembled and assembled, it can always be tightly fitted with the cathode through its own elasticity, thereby ensuring the stability of the electrical connection between the cathode and the power supply.

[0020] The following drawings are provided for use in conjunction with preferred embodiments of the present invention to help understand the objects and advantages of the present invention, wherein: Figure 1 This is a schematic diagram of the structure of the metal ion electrolysis recovery equipment; Figure 2 A schematic diagram of the locking structure. DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and implementation examples.

[0022] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0023] Example 1: This embodiment discloses a metal ion electrolysis recovery device, such as Figure 1 As shown, it includes a liquid storage part 1, an electrolysis part 2 and a pipeline connection part 3 connecting the various components; the liquid storage part 1 is divided into a reaction liquid storage part 102 and a recycled liquid storage part 103 by a separation membrane 101; the electrolysis part 2 includes a plurality of groups of electrolysis units 201. For example, the electrolysis part 2 of this embodiment includes two groups of electrolysis units 201; the pipeline connection part 3 includes a plurality of groups of delivery pumps 301 and a connecting pipeline 302. The delivery pumps 301 and the connecting pipeline 302 can realize the connection between the reaction liquid storage part 102, the recycled liquid storage part 103, the electrolysis unit 201 and the recycling unit 203. The connection between multiple groups of components such as element 201 drives the liquid phase to circulate between different components. After being divided according to functions, the pipeline connection part 3 mainly includes three parts: a receiving working part, an electrolysis working part and a recycling working part. The receiving working part is used to input the external reaction liquid into the reaction liquid storage part 102, the recycling working part is used to output the processed recycled liquid from the recycled liquid storage part 103 to external equipment, and the electrolysis working part is used to circulate the liquid phase between the reaction liquid storage part 102 and the electrolysis unit 201 to ensure the smooth progress of the reaction liquid electrolysis work.

[0024] In this embodiment, the specific structure and working principle of the electrolytic recovery equipment are as follows: The liquid storage part 1 is used to store various liquid phases, and is divided into a reaction liquid storage part 102 and a recycled liquid storage part 103 by a separation membrane 101. The reaction liquid storage part 102 is connected to an external device through a receiving working part and can receive the reaction liquid. For example, in this embodiment, the electrolytic recovery equipment is used to carry out the recovery of silver materials. Before entering the electrolytic recovery equipment, the user leaches the silver material with nitric acid to achieve the recovery of the silver material. Therefore, the reaction liquid received by the electrolytic recovery equipment contains hydrogen ions, silver ions and nitrates, wherein the hydrogen ions and part of the nitrates come from the liquid phase that does not participate in the reaction in the reaction liquid - nitric acid, and at the same time, both are components of the recycled liquid. Therefore, the components of the liquid phase that does not participate in the reaction and the recycled liquid in the present invention are actually different names for the same specific object at different stages. When the liquid phase that does not participate in the reaction is separated from the reaction liquid after subsequent processing, it can be used as recycled liquid to participate in the leaching of the silver material again, and in this embodiment, both refer to nitric acid. For example, the separator 101 in this embodiment uses a COF membrane, which can regulate the pore size and surface charge through a covalent organic framework (COF), selectively allowing small-sized hydrogen ions and specific anions to pass through, while blocking larger-sized metal cations. Therefore, in this embodiment, hydrogen ions and nitrates can pass through the separator 101 and enter the recycled liquid storage section 103, while silver ions remain in the reaction liquid storage section 102, thereby completing the separation between the metal ions and the components of the recycled liquid. Any membrane that can block the passage of metal ions while allowing the components of the recycled liquid to pass through can be used as the separator 101 in the present invention. Accordingly, the recycled liquid storage section 103 can store the recycled liquid that enters through the separator 101, and after being connected to the recycling working section, it can output the collected recycled liquid to an external device so that the recycled liquid can be reused.

[0025] The electrolysis unit 201 includes an inlet, a drain port, an anode 201-1, and a cathode 201-2, wherein both the inlet and drain ports are connected to the reaction liquid storage unit 102 via the electrolysis working unit. During operation, the electrolysis working unit uses a delivery pump 301 and a connecting pipeline 302 to transfer the reaction liquid in the reaction liquid storage unit 102 into the electrolysis unit 201 through the inlet port. The reaction liquid then undergoes an electrolysis reaction between the cathode 201-2 and the anode 201-1, and is finally transported back to the reaction liquid storage unit 102 via the drain port and the connecting pipelines. For example, the inlet port can be placed at the bottom of the electrolysis unit 201, and the drain port can be placed near the top of the side wall of the electrolysis unit 201. This allows the reaction liquid to fully experience the electrolysis reaction between the cathode 201-2 and the anode 201-1 during its upward movement, thereby increasing the probability of metal ion reduction. During the electrolysis process, taking silver nitrate as an example, silver nitrate is first transported to the electrolysis unit 201 for electrolysis. During this period, silver ions are reduced to silver element and no longer move with the liquid phase. The remaining nitrate ions combine with newly generated hydrogen ions to form nitric acid. However, since the electrolysis reaction is usually difficult to proceed completely, the liquid phase discharged from the drain port still contains silver nitrate that has not participated in the electrolysis reaction. When the liquid phase is returned to the reaction liquid storage part 102, the silver ions in the liquid phase will be blocked by the separator 101 and still remain in the reaction liquid storage part 102. This part of the silver ions can participate in the electrolysis reaction again, thereby improving the recovery rate of the metal material, and the newly generated nitric acid can pass through the separator and enter the recycled liquid storage part 103 to complete the separation between the metal ions and the components of the recycled liquid, ensuring that all components in the reaction liquid are utilized and not wasted.

[0026] The present invention achieves shorter transmission paths for various liquid phases during operation of the electrolytic recovery equipment by dividing the liquid storage portion 1, selecting the separation membrane 101, and connecting the pipeline connection portion 3. The number of devices and apparatuses constituting the metal ion reflux system is relatively small, thereby greatly reducing the manufacturing cost of the electrolytic recovery equipment and ensuring that the reflux work can be carried out quickly and adapted to a continuous working rhythm, thereby increasing the overall operating efficiency of the electrolytic recovery equipment.

[0027] Preferably, if Figure 1As shown, the electrolysis unit 201 includes an electrolysis barrel 201-3, an anode 201-1 arranged in the electrolysis barrel 201-3, and a cylindrical cathode 201-2. The cathode 201-2 under this structure can separate the space in the electrolysis barrel 201-3 into a reaction zone and an external discharge zone. The anode 201-1 is placed in the reaction zone, and the infusion port is connected to the reaction zone, so that the reaction liquid output from the infusion port can be placed between the cathode 201-2 and the anode 201-1 and can participate in the electrolysis reaction; an overflow portion 201-2a is provided on the top of the cathode 201-2. When the reaction liquid is continuously input, the liquid phase in the reaction zone will flow upward while participating in the electrolysis reaction, and eventually pass over the overflow portion 201-2a and flow into the external discharge zone. At this time, most of the liquid phase entering the external discharge zone has completed the electrolysis reaction, and can then flow out of the electrolysis unit 201 through the discharge port opened in the external discharge zone and flow back into the reaction liquid storage portion 102. This structure further ensures that the reaction liquid undergoes sufficient electrolysis reaction in the electrolysis unit 201, thereby improving the reduction rate of the metal material and facilitating the efficient recovery of the metal material.

[0028] Preferably, if Figure 1 As shown, the overflow portion 201-2a includes a plurality of overflow holes. In this embodiment, the overflow holes are evenly distributed to further ensure the stability of the liquid overflow speed, thereby ensuring the continuous and stable operation of the entire electrolytic recovery equipment.

[0029] Preferably, if Figure 1 As shown, electrolysis unit 201 also includes a flow guide assembly 201-6 disposed within the reaction zone. A liquid inlet is located at the bottom of the reaction zone. Liquid entering the reaction zone is guided by flow guide assembly 201-6, making contact with cathode 201-2 and flowing toward overflow portion 201-2a. This structure increases the contact area between the reaction liquid and cathode 201-2, thereby more thoroughly reducing the metal ions in the reaction liquid and reducing the amount of liquid that does not participate in the electrolysis reaction.

[0030] Preferably, the metal ion electrolysis recovery device further includes an exhaust portion disposed above the electrolysis section 2 for exhausting the gas phase generated by the reaction in the electrolysis section 2. Exemplarily, in this embodiment, the exhaust portion is used to exhaust oxygen generated during the electrolysis of silver nitrate, thereby reducing the possibility of safety accidents caused by oxygen accumulation.

[0031] Example 2: The difference between the metal ion electrolysis recovery equipment in this embodiment and that in embodiment 1 is that Figure 1As shown, cathode 201-2 is movably mounted within electrolysis barrel 201-3 via first quick-release structure 201-4. This structure allows users to quickly remove cathode 201-2 and recover the metal material attached to it after a period of electrolysis. This significantly improves the overall efficiency of the equipment, resulting in significant economic benefits and engineering application value. First quick-release structure 201-4 can employ any structure or kit that allows for quick assembly and disassembly while ensuring conductivity, such as a snap-on rotary locking mechanism or a hydraulic quick-connect connector.

[0032] Preferably, if Figures 1 and 2 As shown, the first quick-release structure 201-4 includes a latching groove 201-4a provided on the inner bottom surface of the electrolytic barrel 201-3 and a locking structure 201-4b provided at the top edge of the electrolytic barrel 201-3. When the cathode 201-2 is installed, its bottom is first inserted into the latching groove 201-4a to preliminarily fix the position of the cathode 201-2 in the electrolytic barrel 201-3, and then the locking structure 201-4b is used to completely fix the cathode 201-2. For example, as shown in FIG. Figures 1 and 2 As shown, the locking structure 201-4b in this embodiment includes a latch hole provided on the cathode 201-2, a fixing pin 201-4b-1, and a fixing base 201-4b-2 provided on the electrolytic barrel 201-3. When the fixing pin 201-4b-1 passes through the latch hole from top to bottom and is fixed on the fixing base 201-4b-2, the position locking of the cathode 201-2 is completed. At the same time, as Figure 2 As shown, the locking structure 201-4b also includes an elastic fitting kit 201-4c. In this embodiment, the elastic fitting kit 201-4c uses a spring structure, but any other structure or kit with elastic deformation ability and conductivity is also applicable. When the first quick-release structure 201-4 completes the installation and fixation of the cathode 201-2, one end of the elastic fitting kit 201-4c contacts and fits the cathode 201-2, and the other end is connected to the power source 4. In this embodiment, the fixing base is conductive. Therefore, the elastic fitting kit 201-4c is in contact with the cathode 201-2 at one end and in contact with the fixing base at the other end, thereby ensuring the stability of the electrical connection between the cathode 201-2 and the power source 4. Under the conventional locking structure 201-4b, in order to ensure a stable connection between the cathode 201-2 and the power supply 4, a more precise locking connection structure needs to be used. After multiple disassembly and assembly operations, the loss of such a locking connection structure can easily cause a decrease in the stability of the electrical connection. The elastic fitting kit 201-4c utilizes its own elastic deformation ability to achieve a tight fit with the cathode 201-2 after multiple disassembly and assembly operations, thereby ensuring the stability of the electrical connection during long-term use.

[0033] Preferably, if Figure 1As shown, anode 201-1 is movably mounted within electrolysis barrel 201-3 via second quick-release structure 201-5. This allows for quick replacement of anode 201-1 when electrochemical corrosion or other maintenance work is required. In this embodiment, second quick-release structure 201-5 is also conductive, allowing it to be used to establish an electrical connection between anode 201-1 and power source 4.

[0034] Preferably, if Figure 1 As shown, the second quick-release structure 201-5 includes a threaded fastening kit disposed at the bottom of the anode 201-1. The threaded fastening kit can ensure that the anode 201-1 is firmly installed in the electrolysis barrel 201-3. On the other hand, it can ensure the stability of the electrical connection between the anode 201-1 and the power supply 4, ensuring the long-term stable operation of the electrolytic recovery equipment.

[0035] Example 3: This embodiment provides a material recovery production line. For example, this recycling production line primarily recovers silver from battery cells. The recycling production line includes a silvering tank capable of accommodating battery cells and nitric acid. This silvering tank is connected to the metal ion electrolysis recovery equipment described in Example 1. This tank can transfer a liquid phase containing silver ions to the metal ion electrolysis recovery equipment for further silver material recovery. It can also receive the recovered liquid provided by the metal ion electrolysis recovery equipment for effective reuse.

[0036] In actual recycling work, since there is huge uncertainty in the stacking form, size, and specifications of the battery cells that are defective products, the concentration of silver ions that can be leached by nitric acid each time is not a fixed value, that is, when entering the metal ion electrolysis recovery equipment, the relationship between the silver ion content and the nitrate content in the liquid phase varies greatly, but the nitrate content is usually higher. When the metal ion electrolysis recovery equipment of the present invention is used, since the recycling working part can pump the recycled liquid outward, thereby providing power for the movement of the components of the recycled liquid, the nitrate and hydrogen ions in the reaction liquid storage part 102 will enter the recycled liquid storage part 103 in large quantities, thereby ensuring that the concentration relationship between silver ions and nitrate ions in the reaction liquid storage part 102 and the electrolysis part 2 is adjusted to be close to 1:1, avoiding the occurrence of situations such as the electrolysis reaction being difficult to carry out efficiently due to the nitrate content being too high relative to the silver ion content, greatly improving the efficiency of the metal ion electrolysis reaction, so that the metal ion electrolysis recovery equipment of the present invention meets the efficient working requirements of the material recovery production line.

[0037] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
