Description

Technical Field

[0001] The present application relates to the field of precious metal recovery, and in particular to an electrolytic cell for extracting precious metals. Background Art

[0002] A precious metal electrolyzer is a device used to extract precious metals (such as gold, silver, platinum, etc.). Its main function is to separate precious metals from raw materials through electrolysis. Precious metals usually exist in the form of ores or other metal-containing compounds, and the electrolyzer uses the action of electric current and electrolyte to dissolve the precious metals from the raw materials and deposit them on the electrodes to achieve the extraction and purification process.

[0003] Traditional electrolytic cells for extracting precious metals are usually designed to contact the precious metal raw materials to be extracted with the electrolyte so as to carry out an electrolytic reaction and thus extract the precious metals. In order to increase the efficiency of electrolysis, the raw materials are often ground into small particles to ensure sufficient surface area for contact with the electrolyte and promote the release of precious metals. However, there are some problems with this approach, namely that small particles of precious metal raw materials will form difficult-to-handle waste slag after being completely extracted. These waste slags remain inside the electrolytic cell, which not only affects the efficiency of the next round of electrolysis, but also may cause damage to the equipment and make cleaning difficult. Especially for precious metal raw materials, the legacy of waste slag may lead to the loss of precious metals, thereby affecting production costs and resource utilization efficiency.

[0004] Therefore, it is necessary to design an electrolytic cell for extracting precious metals that can quickly clean the waste residue in the electrolytic cell to solve the problem that the raw material waste residue generated by the traditional electrolytic cell for extracting precious metals is difficult to clean out of the electrolytic cell.

[0032] An electrolytic cell body, wherein the electrolytic cell body has a material placement portion, and the precious metal raw materials to be extracted are placed in the material placement portion;

The electrolytic cell for extracting precious metals provided above is provided with a valve on the electrolytic cell body, one end of which is connected to the outside world and the other end of which is connected to the material storage part. At the same time, a feeding cart is provided on one side of the electrolytic cell body, and the valve is located between the electrolytic cell body and the feeding cart. When the precious metal raw materials are completely extracted, the waste residue can be discharged into the feeding cart through the valve, which is convenient for the collection and treatment of the waste residue.

[0036] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] See also Figure 1-Figure 5 The embodiment of the present application provides an electrolytic cell 100 for extracting precious metals, comprising an electrolytic cell body 1, a valve 2, a feeding trolley 3 and a support frame 4. The electrolytic cell body 1 has a material placement portion 11, and the precious metal raw materials to be extracted are placed in the material placement portion 11. The valve 2 is provided on the electrolytic cell body 1, and one end of the valve 2 is connected to the outside and the other end is connected to the material placement portion 11. The feeding trolley 3 is located on the side of the electrolytic cell body 1 where the valve 2 is provided, and the valve 2 is located between the electrolytic cell body 1 and the feeding trolley 3. The raw material waste residue after the precious metals are extracted is discharged into the feeding trolley 3 through the valve 2. The electrolytic cell body 1 is arranged on the support frame 4, and the side of the support frame 4 away from the electrolytic cell body 1 has a bottom surface 41 perpendicular to the direction of gravity. In the direction of gravity, the distance a from the electrolytic cell body 1 to the bottom surface 41, the distance b from the valve 2 to the bottom surface 41, and the distance c from the feeding cart 3 to the bottom surface 41 satisfy the relationship: a>b>c.

[0038] Specifically, the electrolytic cell body 1 serves as the space required to accommodate the electrolytic reaction, and the material placement part 11 is used to place the precious metal raw materials to be extracted. Through these two components, the precious metal raw materials can be fully in contact with the electrolyte, thereby realizing the electrolytic reaction. The precious metal raw materials are placed in the material placement part 11 and in contact with the electrolyte. During the electrolysis process, the precious metals are dissolved into ion form and deposited on the negative electrode. The valve 2 is used to control the discharge of the waste slag, one end of which is connected to the outside world and the other end is connected to the material placement part 11. This design makes the discharge of the waste slag more convenient and accurate. When the precious metal raw materials are completely extracted, the valve 2 is opened, and the waste slag is discharged into the feeding cart 3 through the valve 2. It is suitable for production processes that require regular removal of waste slag to improve production efficiency and equipment cleanliness. The feeding cart 3 is used to collect and transport the raw material waste slag after the precious metals are extracted, avoiding the problem of waste slag remaining inside the electrolytic cell. The waste slag is discharged into the feeding cart 3 through the valve 2, and the feeding cart 3 can be easily removed for waste slag treatment and cleaning. The support frame 4 provides a stable support platform to ensure the stable placement of the electrolytic cell body 1 and ensure the smooth discharge of the waste residue through the specified distance relationship. The support frame 4 is connected to the electrolytic cell body 1 by bolts to maintain a stable position. The vertical bottom surface 41 at the bottom of the support frame 4 and the set distance relationship ensure the smooth discharge of the waste residue. The direction of gravity refers to the direction in which the earth attracts objects, usually pointing to the center of the earth. On the surface of the earth, the direction of gravity is perpendicular to the surface and acts downward.

[0039] Furthermore, the distance (a) from the electrolytic cell body 1 to the bottom surface 41 determines the height at which the waste residue is discharged from the electrolytic cell body 1. By placing the electrolytic cell body 1 on the support frame 4, the waste residue can naturally flow from a higher position to the bottom surface 41 under the action of gravity, and then be discharged into the feeding cart 3. The valve 2 is located on the electrolytic cell body 1. By adjusting the distance (b) from the valve 2 to the bottom surface 41, the speed and flow rate of the waste residue discharge can be controlled. Ensure that the valve 2 is located at a lower position than the electrolytic cell body 1 so that the waste residue can be discharged smoothly and flow to the feeding cart 3. As a collection container for the waste residue, the feeding cart 3 should be located lower than the valve 2. The distance (c) from the feeding cart 3 to the bottom surface 41 should be less than the distance from the electrolytic cell body 1 to the bottom surface 41 and the distance from the valve 2 to the bottom surface 41 to ensure that the waste residue can be smoothly collected in the feeding cart 3 after being discharged.

[0040] In a specific example, the material placement portion 11 includes a connection port 111 , the material placement portion 11 is communicated with the valve 2 through the connection port 111 , and the connection port 111 is detachably connected to the valve 2 .

[0041] Specifically, the material placement part 11 is an area in the electrolytic cell for placing the precious metal raw materials to be extracted. It is usually located at a specific position of the electrolytic cell to ensure that the precious metal raw materials are fully in contact with the electrolyte, so as to carry out an effective electrolytic reaction. A connection port 111 is provided on the material placement part 11 for connecting to the valve 2. This connection port 111 is a physical interface that allows the material placement part 11 to be directly connected to the valve 2 and ensures that the passage between the two is unobstructed. The connection between the connection port 111 and the valve 2 is detachable, which means that they can be easily connected and separated. This design allows the material placement part 11 to be easily removed for cleaning, replacement or maintenance. When the electrolytic cell needs to be emptied or the precious metal raw materials need to be replaced, the material placement part 11 can be easily removed without having to perform cumbersome operations on the entire electrolytic cell. Through the connection of the connection port 111 to the valve 2, the material placement part 11 forms a connecting channel with other parts of the electrolytic cell. This design ensures that the precious metal raw materials can smoothly enter the electrolytic cell when needed, and also facilitates the discharge of waste slag. During use, operators can easily remove the material receiving part 11 by disassembling the connection between the connection port 111 and the valve 2. Then, they can clean the residue in the material receiving part 11, replace new precious metal raw materials, or perform maintenance operations. After completion, they can connect the material receiving part 11 to the valve 2 again to reconnect it with the electrolytic cell and prepare to start the next round of precious metal extraction process.

[0042] In a specific example, the electrolytic cell body 1 also includes a reaction box 12, which is located on a side of the material loading portion 11 away from the valve 2, and is communicated with the material loading portion 11. The reaction box 12 is provided with an infusion port 121 and an outlet port 122, and the electrolyte flows into or is discharged from the electrolytic cell body 1 through the infusion port 121 and the outlet port 122.

[0043] Specifically, the reaction box 12 is a component of the electrolytic cell body 1, and is located on the side of the feeding part 11 away from the valve 2. It is usually located at a specific position of the electrolytic cell, connected to the feeding part 11, and forms an integral structure with the electrolytic cell body 1. The reaction box 12 is connected to the feeding part 11, which means that the electrolyte in the electrolytic cell can flow freely between the reaction box 12 and the feeding part 11. This connectivity ensures that the precious metal raw material is in full contact with the electrolyte, thereby promoting the dissolution and electrolysis process of the precious metal. The reaction box 12 is provided with an infusion port 121 and an outlet 122 for the input and output of the electrolyte. The infusion port 121 is used to introduce fresh electrolyte into the reaction box 12, while the outlet 122 is used to discharge the electrolyte that has been used. The positions and sizes of these two ports are usually designed to suit the operating requirements of the electrolytic cell to ensure that the flow of the electrolyte is smooth and stable. The electrolyte flows into the reaction box 12 through the infusion port 121, and then contacts and reacts with the precious metal raw material in the reaction box 12. Subsequently, the electrolyte after the reaction is discharged through the liquid outlet 122 and continues to be recycled in the electrolytic cell, or is further processed and reused. This process ensures the recycling of the electrolyte and the continuous electrolysis process.

[0044] In a specific example, the material placement portion 11 has an inclined surface 112, one end of the inclined surface 112 intersects with the connection port 111, and the other end intersects with the inner side of the reaction box 12, and the angle d between the inclined surface 112 and the gravity direction satisfies the relationship: 50°≤d≤60°;

[0045] The angle e between the inclined surface 112 and the bottom surface 41 satisfies the relationship: 30°≤e≤40°.

[0046] Specifically, inside the material placement part 11, a slope 112 is designed, one end of which intersects with the connection port 111 and the other end intersects with the inner side of the reaction box 12. The design of this slope 112 allows the waste slag after electrolysis to flow smoothly on the slope 112 and gather near the connection port 111 for easy discharge. The angle d between the slope 112 and the gravity direction is in the range of 50° to 60°. The selection of this range takes into account two aspects: first, a larger angle can ensure the smooth flow of the waste slag on the slope 112 and prevent accumulation or jamming; second, the size of the angle should also take into account the natural sliding speed of the waste slag under the action of gravity to ensure that the waste slag can flow smoothly to the connection port 111. The angle e between the slope 112 and the bottom surface 41 is in the range of 30° to 40°. The selection of this range is intended to ensure the stable sliding of the waste slag on the slope 112 and to flow smoothly to the bottom, thereby entering the reaction box 12. A smaller angle can provide a sufficient inclination of the inclined surface 112 while not being too steep, thereby avoiding accumulation or blockage of waste residue.

[0047] In a specific example, an axis parallel to the gravity direction is referred to as a first axis, and the material placement portion 11 has four inclined surfaces 112 , and the four inclined surfaces 112 are arranged around the first axis.

[0048] Specifically, in the electrolytic cell, we define an axis parallel to the direction of gravity, which is called the first axis. This axis is usually used as a reference line to determine the position and arrangement of the inclined plane 112. Four inclined planes 112 are designed inside the feeding part 11, which are respectively located in the four directions of the electrolytic cell and surround the first axis. This means that the four inclined planes 112 are evenly distributed around the feeding part 11, and each inclined plane 112 has a certain distance from the first axis, so that the precious metal raw materials can be evenly distributed in all directions. These inclined planes 112 are arranged in a form surrounding the first axis, which means that they present a surrounding arrangement. Such a design can ensure that the precious metal raw materials are evenly distributed inside the feeding part 11, so that the entire extraction process can be carried out more balanced and efficiently. By arranging the four inclined planes 112 around the first axis, it can be ensured that the precious metal raw materials are fully covered and evenly distributed inside the feeding part 11. Such an arrangement design helps to improve the electrolysis efficiency, increase the contact area of ​​the precious metals, thereby improving the extraction efficiency and ensuring the stability of production.

[0049] In a specific example, a cover plate 5 is provided on a side of the reaction box 12 away from the material placement portion 11 .

[0050] Specifically, the reaction box 12 is a part of the electrolytic cell, which is used to accommodate waste residue or other substances generated during the electrolysis process. It is usually located on one side of the electrolytic cell, away from the material loading part 11, so as to be separated from the material loading part 11 and more convenient to operate. On one side of the reaction box 12, that is, the side away from the material loading part 11, a cover plate 5 is covered. This cover plate 5 is usually a flat plate or a removable cover, which is used to close the opening of the reaction box 12 to prevent waste residue or other substances from overflowing or diffusing inside and outside the reaction box 12. The main function of the cover plate 5 is to ensure the sealing and safety of the reaction box 12. By covering the cover plate 5, waste residue or other substances can be prevented from overflowing inside and outside the reaction box 12, thereby avoiding environmental pollution or causing operational problems. In addition, the cover plate 5 can also protect the interior of the reaction box 12 from the influence of the external environment, such as dust, debris, etc.

[0051] In a specific example, a handle 51 is provided on a side of the cover plate 5 away from the reaction box 12 .

[0052] Specifically, the cover plate 5 is a component covering the opening of the reaction box 12, which is used to close the reaction box 12 and protect its interior from the external environment. In this feature, the cover plate 5 is arranged on the side away from the reaction box 12. A handle 51 is provided on the side of the cover plate 5 away from the reaction box 12, that is, the side of the cover plate 5. The handle 51 is usually a raised component, which is used to conveniently open and close the cover plate 5, as well as to install and remove the cover plate 5. The main function of the handle 51 is to provide a convenient operating handle so that the operator can easily open and close the cover plate 5. By grasping the handle 51, the operator can easily lift or put down the cover plate 5 without directly contacting the surface of the cover plate 5, thereby reducing the complexity and inconvenience of the operation. The setting of the handle 51 also helps to improve the safety of the operation. The operator can firmly control the movement of the cover plate 5 through the handle 51, avoiding the occurrence of hand slippage or accidental injury, and ensuring the safety and stability of the operation process.

[0053] In a specific example, the reaction box 12 has a gripping portion 123 on the outside thereof, and the gripping portion 123 protrudes from the reaction box 12 .

[0054] Specifically, the gripping portion 123 is a raised portion specially designed on the outside of the reaction box 12, usually in the form of a handle or grip, which is used to facilitate the operator to grasp and lift the reaction box 12. The gripping portion 123 is located on the outside of the reaction box 12, usually distributed on both sides or around the reaction box 12. This design allows the operator to easily find the gripping portion 123, and can conveniently lift the entire reaction box 12 when needed. The gripping portion 123 protrudes from the surface of the reaction box 12, which means that they have a certain bulge or protrusion compared to the surface of the reaction box 12. This design makes the gripping portion 123 easier to identify and grasp, and can effectively prevent hand slips or mistakes. The main function of the gripping portion 123 is to provide a convenient handle so that the operator can easily grasp and lift the reaction box 12. Through the gripping portion 123, the operator can more firmly control the movement of the reaction box 12, thereby improving the convenience and safety of operation.

[0055] In a specific example, the reaction box 12 and the material placement portion 11 are integrally formed.

[0056] Specifically, the reaction box 12 and the material holding part 11 are integrally formed, which means that they are manufactured as an integral unit, rather than being manufactured separately and then assembled. During the manufacturing process, the structures of the reaction box 12 and the material holding part 11 are manufactured simultaneously to ensure their tightness and integrity. The integral forming of the reaction box 12 and the material holding part 11 means that their structures are tightly integrated without obvious separation parts. This design can reduce the seams or gaps that may appear during the assembly process, and improve the sealing and stability of the equipment. The one-piece design has the advantages of simple structure, stability and reliability. Compared with the traditional method of separate manufacturing and then assembly, the one-piece molding can reduce the number of parts and the process steps in the assembly process, reducing the manufacturing cost and production cycle. The design of the reaction box 12 and the material holding part 11 being integrally formed is common in equipment with high structural requirements and good sealing and stability, such as electrolytic cells. This design can ensure the performance and reliability of the equipment and has a wide range of applications in the fields of extracting precious metals.

[0057] In a specific example, the electrolytic cell body 1 is connected to the support frame 4 by bolts.

[0058] Specifically, bolt connection is a common mechanical connection method, which is achieved by passing the bolts through the holes and tightening them with nuts to achieve a fixed connection between the two parts. In this feature, this connection method is adopted between the electrolytic cell body 1 and the support frame 4. Through the bolt connection, the electrolytic cell body 1 and the support frame 4 are firmly fixed together, making them an integral unit. This connection method can ensure that the equipment will not loosen or fall off during operation, thereby improving the stability and reliability of the equipment. One of the advantages of bolt connection is convenient disassembly and maintenance. When the electrolytic cell needs to be maintained or parts need to be replaced, the electrolytic cell body 1 can be separated from the support frame 4 by simply loosening the bolts, which is convenient for maintenance operations. The bolt connection also has certain adjustability and adaptability, and can be adjusted and aligned as needed to ensure the tightness and stability of the connection. This feature makes the connection between the electrolytic cell body 1 and the support frame 4 more flexible and can adapt to different installation environments and requirements.

[0059] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the creative concept of the present application, but these improvements are within the scope of protection of the present application.
