Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic cell electrode systems, and specifically to an electrolytic cell electrode system. Background Technology

[0002] The electrode system in an electrolytic cell used for electrolyzing conductive metal powders mainly consists of an anode, a cathode, and related conductive components, and is the core component for achieving electrolytic deposition of metal ions. The electrode system is connected to an external power source via conductive copper busbars or busbars to form a closed circuit. The spacing, arrangement, and surface condition of the electrodes affect key indicators such as current distribution, deposition efficiency, and copper powder particle size during electrolysis. Its design must consider multiple aspects, including electrolysis efficiency, energy consumption, and copper powder quality.

[0003] In traditional electrolytic copper powder processing, the electrode system of the electrolytic cell generally adopts an array arrangement of multiple cathodes and anodes arranged alternately in parallel. This structure requires the installation of the same number of electrical contacts as the anode and cathode. Due to the large number of contacts, the installation and debugging are complex, and the probability of poor contact is relatively high, resulting in uneven current distribution among the cathodes. This leads to differences in the copper powder deposition rate and the anode consumption rate. Furthermore, since each cathode surface needs to be scraped, the dense arrangement of the cathodes makes the copper powder stripping process inefficient. Utility Model Content

[0004] The purpose of this invention is to provide an electrolytic cell electrode system in order to solve the above problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution, including:

[0006] An electrolytic cell is used to hold the electrolyte and provide a reaction chamber for the electrolytic reaction.

[0012] As a further description of the above technical solution, a supporting crossbeam is symmetrically connected in the middle of the electrolytic cell, and the supporting crossbeam is used to support the first conductive busbar and the second conductive busbar.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figures 1-8 As shown, in one embodiment, an electrolytic cell electrode system includes: an electrolytic cell body 1, a first electrolytic component 2, and a second electrolytic component 3.

[0036] The electrolytic cell 1 is used to hold the electrolyte and provide a reaction chamber for the electrolytic reaction; the first electrolytic component 2 is installed on the electrolytic cell 1 and is used to provide metal ions or obtain electrons from anions in the electrolyte; the second electrolytic component 3 is installed between the first electrolytic components 2 and is used to provide deposited metal ions.

[0037] Specifically, the first electrolysis assembly 2 includes a first conductive busbar 21, a long strip-shaped conductor made of high-purity conductive metal (such as copper), with a cross-sectional area designed according to the current. First terminals 22, which are metal pillars, are mounted on the first conductive busbar 21, exhibiting good conductivity and corrosion resistance. A first electrode plate 23, which is square-shaped, is mounted on the first terminal plate 22. The first electrode plate 23 can be made of an insoluble anode (such as lead alloy), which can gain electrons from anions (such as hydroxide ions) in the electrolyte during electrolysis, exhibiting good corrosion resistance and maintaining stability during electrolysis. Alternatively, the first electrode plate 23 can be made of a soluble anode (such as copper or nickel), which can directly provide metal ions during electrolysis.

[0038] Correspondingly, the second electrolysis component 3 includes a second conductive busbar 31, which is also a long strip-shaped conductor made of high-purity conductive metal (such as copper), with the cross-sectional area designed according to the current. The second conductive busbar 31 is equipped with a second terminal block 32, which is also a metal column with good conductivity and corrosion resistance. The second terminal block 32 is equipped with a second electrode plate 33, which is also a square plate made of corrosion-resistant and highly conductive metal (such as stainless steel, titanium, etc.), with good corrosion resistance, and can remain stable during electrolysis.

[0039] Understandably, the anode / cathode electrode plates are regularly spaced within the electrolytic cell 1 via terminals, which effectively reduces the number of electrical contacts required. Structurally, this reduces the probability of poor contact caused by oxidation, loosening, or installation errors of the electrical contacts, making the current conduction in the electrode system more stable, thereby ensuring the uniformity of copper powder deposition and anode consumption on each electrode plate.

[0040] It should be explained in detail that the electrolytic cell body 1 is provided with interconnected conductive plates 24 along its edge, and the interconnected conductive plates 24 are electrically connected to multiple sets of first terminals 22. This allows multiple first conductive bars 21 to be connected to form a whole, so that the current can be distributed more evenly in the first electrolysis component 2, reducing the current difference between multiple first electrode plates 23, thereby effectively solving the problem of inconsistent anode metal ion consumption rate.

[0041] Please continue reading. Figures 1-8In this embodiment, a support beam 11 is symmetrically connected in the middle of the electrolytic cell 1 to support the first conductive busbar 21 and the second conductive busbar 31, so as to ensure that the first conductive busbar 21 and the second conductive busbar 31 remain stable in the electrolytic cell 1 and avoid positional displacement due to gravity or other factors, which would affect the electrolysis effect.

[0042] For example, multiple sets of first terminals 22 are sleeved on the outside of the first conductive busbar 21, and a first electrode plate 23 is suspended at the bottom of each set of first terminals 22. Specifically, a first lap post 25 is installed at the end of the first conductive busbar 21, and the first lap post 25 overlaps with the interconnecting conductive sheet 24 to ensure that the interconnecting conductive sheet 24 overlaps with the first conductive busbar 21 to form a good electrical connection; while a first support post 26 is installed in the middle of the first conductive busbar 21, and the first support post 26 is connected to the support beam 11 to prevent the first conductive busbar 21 from deforming or shifting position due to gravity or vibration during the electrolysis process.

[0043] Correspondingly, multiple sets of second terminals 32 are sleeved on the outside of the second conductive busbar 31, and a second electrode plate 33 is suspended at the bottom of each set of second terminals 32. Specifically, a second overlapping post 34 is installed at the end of the second conductive busbar 31, and the second overlapping post 34 overlaps with the electrolytic cell body 1; while a second support post 35 is installed in the middle of the second conductive busbar 31, and the second support post 35 is connected to the support beam 11 to prevent the second conductive busbar 31 from deforming or shifting position due to gravity or vibration during the electrolysis process.

[0044] It should be explained in detail that the first electrode plate 23 and the adjacent second electrode plate 33 are suspended coaxially, that is, the central axes of the first electrode plate 23 and the adjacent second electrode plate 33 are on the same straight line, so that the two are arranged along the same axial direction in the electrolytic cell, which creates a regular electric field distribution in the electrolytic cell, ensuring that the current can be uniformly conducted between the first electrode plate 23 and the second electrode plate 33 along the axial direction. Furthermore, the first electrode plate 23 and the adjacent second electrode plate 33 are suspended perpendicularly, that is, the plate surface of the first electrode plate 23 is perpendicular to the plate surface of the adjacent second electrode plate 33. This increases the flow path of the electrolyte around the electrode plates, which helps to improve the ion transport efficiency in the electrolyte, promotes the electrolytic reaction, and also facilitates the uniform deposition of copper powder on the electrode plate surface, and makes it easier for the subsequent copper powder scraping process.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
