[0038] In one aspect of the present invention, the present invention provides a silver electrolysis device, which is suitable for production operations in various silver electrolysis refineries. Figure 1-2 The silver electrolysis device includes: an electrolytic cell shell 10, a cathode conductive busbar 20, an anode conductive busbar 30, a conductive block 40, a conductive beam 50, a cathode plate 60 and an anode plate 70.

[0039] The silver electrolysis device according to the embodiment of the present invention is further described in detail below.

[0040] According to an embodiment of the present invention, referring to Figure 1-6 The electrolytic cell shell 10 can be set as a rectangular shell with an open top for placing electrolyte; the cathode conductive busbar 20 can be set at the top of the side wall on one side of the electrolytic cell shell 10, and the anode conductive busbar 30 is set at the top of the side wall on the other side of the electrolytic cell shell 10 and is arranged opposite to the cathode conductive busbar 20; the conductive block 40 is connected to the cathode conductive busbar 20, and a protrusion 41 is provided on one side of the conductive block 40; the conductive beam 50 includes a conductive beam body 51 and an anti-corrosion layer 52, one end of the conductive beam body 51 has a connecting portion 511, the anti-corrosion layer 52 is formed on the surface of the conductive beam body 51 and has a notch 521 corresponding to the connecting portion 511, and the protrusion 41 passes through the notch 521 and is connected to the connecting portion 511; the top of the cathode plate 60 is connected to the anti-corrosion layer 52 at the bottom of the conductive beam 50; one end of the anode plate 70 is connected to the anode conductive busbar 30. By forming an anti-corrosion layer 52 on the surface of the conductive beam body 51, the conductive beam 50 can be prevented from being corroded and producing verdigris during the electrolysis process, thereby improving the conductivity of the conductive beam 50, improving the system electrical efficiency, reducing the residual pole rate, and preventing the produced verdigris from entering the obtained silver powder, solving the problem of excessive copper in the silver powder; in addition, the conductive block 40 is connected to the cathode conductive busbar 20, and a protrusion 41 is provided on one side of the conductive block 40, and a connecting portion 511 is provided at one end of the conductive beam body 51. The anti-corrosion layer 52 is formed on the surface of the conductive beam body 51 and has a notch 521 corresponding to the connecting portion 511. The protrusion 41 passes through the notch 521 on the anti-corrosion layer 52 and is connected to the connecting portion 511 on the conductive beam body 51, so that the conductive beam body 51 can be closely fitted with the conductive block 40, which is further beneficial to improving the conductivity of the conductive beam body 51, improving the system electrical efficiency, and reducing the residual pole rate.

[0041] According to an embodiment of the present invention, referring to Figure 1-2 The cathode conductive busbar 20 has a first slot 21 evenly arranged along its length, and one end of the conductive beam 50 is engaged with the first slot 21, thereby facilitating the installation and removal of the conductive beam 50 and the cathode plate 60. Similarly, the anode conductive busbar 30 has a second slot 31 evenly arranged along its length, and one end of the anode plate 70 is engaged with the second slot 31, thereby facilitating the installation and removal of the anode plate 70. Further, the conductive block 40 can be welded to the cathode conductive busbar 20.

[0042] According to the embodiment of the present invention, the materials of the cathode plate 60 and the anti-corrosion layer 52 are not particularly limited, and those skilled in the art can select them according to actual needs. For example, the material of the cathode plate 60 can be titanium, and the material of the anti-corrosion layer 52 can be the same as the material of the cathode plate 60. Thus, the anti-corrosion layer 52 can prevent the conductive beam body 51 from being corroded during the electrolysis process to produce patina, thereby improving the conductivity of the conductive beam 50, improving the system electrical efficiency, reducing the residual pole rate, and preventing the generated patina from entering the obtained silver powder, thereby solving the problem of excessive copper in the silver powder.

[0043] According to the embodiment of the present invention, the materials of the conductive beam body 51 and the conductive block 40 are not particularly limited, and those skilled in the art can select them according to actual needs. For example, the material of the conductive beam body 51 can be copper, and the material of the conductive block 40 can be the same as that of the conductive beam body 51. This is further beneficial to improving the conductivity of the conductive beam body 51, improving the system electrical efficiency, and reducing the residual pole rate.

[0044] As a specific example, the conductive beam 50 can be obtained by completely and tightly compounding a titanium sleeve and a copper rod through a rolling process. The titanium sleeve forms an anti-corrosion layer 52, and the copper rod forms the conductive beam body 51. It is not easy to delaminate, which can greatly reduce the corrosion of the electrolyte to the conductive beam body 51, and at the same time reduce the current resistance of the conductive beam 50, thereby ensuring the quality of the silver powder.

[0045] According to an embodiment of the present invention, referring to Figure 1-6 The specific way of connecting the protruding portion 41 and the connecting portion 511 is not particularly limited, and those skilled in the art can select it according to actual needs. As a specific example, the protruding portion 41 can have a first through hole 42, and the connecting portion 511 can have a second through hole 512. The protruding portion 41 and the connecting portion 511 are fixedly connected by a bolt 43 that passes through the first through hole 42 and the second through hole 512, and the bolt 43 can be threadedly connected with a nut 44. Thus, the conductive beam body 51 and the conductive block 40 can be closely attached and fixedly connected together by the bolt 43 and the nut 44, which is further beneficial to improve the conductivity of the conductive beam body 51, improve the system efficiency, reduce the residual pole rate, and play a role in fixing the cathode plate 60 through the conductive block 40, so as to prevent the scraper from driving the cathode plate 60 to move forward and backward during the movement of scraping silver powder.

[0046] According to an embodiment of the present invention, the connection method between the top of the cathode plate 60 and the anti-corrosion layer 52 at the bottom of the conductive beam 50 is not particularly limited, and those skilled in the art can choose according to actual needs. As a specific example, the top of the cathode plate 60 can be welded to the anti-corrosion layer 52 at the bottom of the conductive beam 50 using a double-sided seamless welding process.

[0047] According to an embodiment of the present invention, the thickness of the anti-corrosion layer 52 may be 1.4 mm to 1.6 mm, for example, 1.4 mm, 1.42 mm, 1.44 mm, 1.46 mm, 1.48 mm, 1.5 mm, 1.52 mm, 1.54 mm, 1.56 mm, 1.58 mm, 1.6 mm, etc. The inventors have found that if the thickness of the anti-corrosion layer 52 is too large, the resistance of the conductive beam 50 will increase. If the thickness of the anti-corrosion layer 52 is too small, the anti-corrosion layer 52 may be damaged due to collision and wear during installation and removal from the slot, thereby losing the protective effect on the conductive beam body 51. The present invention controls the thickness of the anti-corrosion layer 52 within the above range, which can not only protect the conductive beam body 51, but also improve the conductivity of the conductive beam body 51, improve the system electrical efficiency, and reduce the residual pole rate.

[0048] According to an embodiment of the present invention, the thickness of the protrusion 41 is not less than the thickness of the anti-corrosion layer 52. Thus, the protrusion 41 can pass through the notch 521 on the anti-corrosion layer 52 and fit tightly with the connecting portion 511 on the conductive beam body 51. This is further beneficial to improving the conductivity of the conductive beam body 51, enhancing the system electrical efficiency, and reducing the residual pole rate.

[0049] According to an embodiment of the present invention, the thickness of the conductive beam body 51 is 2.8 mm to 3.2 mm, for example, it can be 2.8 mm, 2.85 mm, 2.9 mm, 2.95 mm, 3.0 mm, 3.05 mm, 3.10 mm, 3.15 mm, 3.2 mm, etc. The inventor found that if the thickness of the conductive beam body 51 is too large, the conductive beam 50 formed will be too thick, and the gap between the cathode scraper and the cathode plate 60 arranged outside the conductive beam 50 will be too large, which will easily lead to the accumulation of electrolytic silver powder and cause a short circuit at the bottom of the electrolysis device; if the thickness of the conductive beam body 51 is too small, it will affect the conductivity and strength of the conductive beam 50. The present invention controls the thickness of the conductive beam body 51 within the above range, which can not only reduce the accumulation of electrolytic silver powder and avoid a short circuit at the bottom of the electrolysis device, but also ensure that the conductivity and strength of the conductive beam 50 can meet the requirements of large plate and high current density operation. It can be understood that other structures of the silver electrolysis device, such as the cathode scraper, are all prior art, so they will not be described one by one here.

[0050] According to an embodiment of the present invention, referring to Figure 3The notch 521 may be square, and the side length of the notch 521 may be 28 mm to 32 mm, for example, 28 mm, 28.5 mm, 29 mm, 29.5 mm, 30 mm, 30.5 mm, 31 mm, 31.5 mm, 32 mm, etc. The inventors have found that by controlling the side length of the notch 521 within the above range, it is possible to ensure that the electrolysis device can be used normally when the silver electrolysis current is increased to the designed maximum value of 1000 A. Furthermore, the shape and size of the protrusion 41 and the connecting portion 511 may be the same as the notch 521, so that the protrusion 41 and the notch 521 are closely fitted to transmit current.

[0051] According to an embodiment of the present invention, referring to Figure 1 The other end of the anode plate 70 can be placed on the top of the side wall of one side of the electrolytic cell shell 10, and there is a gap between the anode plate 70 and the cathode conductive busbar 20 to prevent the anode plate 70 from contacting the cathode conductive busbar 20.

[0052] According to an embodiment of the present invention, referring to Figure 1 One end of the conductive beam 50 close to the protrusion 41 can be placed on the cathode conductive busbar 20, and the other end of the conductive beam 50 can be placed on the top of the side wall on the other side of the electrolytic cell shell 10, with a gap between the conductive beam 50 and the anode conductive busbar 30 to prevent the conductive beam 50 from contacting the anode conductive busbar 30.

[0053] The present invention is described below with reference to specific embodiments. It should be noted that these embodiments are merely illustrative and do not limit the present invention in any way.

The other end of the conductive beam 50 is placed on the top of the side wall on the other side of the electrolytic cell shell 10, and there is a gap between the conductive block 40 and the cathode conductive busbar 20. A protrusion 41 is provided on one side of the conductive block 40. The conductive beam 50 includes a conductive beam body 51 and an anti-corrosion layer 52. One end of the conductive beam body 51 has a connecting portion 511. The anti-corrosion layer 52 is formed on the surface of the conductive beam body 51.
