Description

Technical Field

[0001] This utility model relates to the field of anode structure technology, and more specifically to a clamp-type titanium-based composite anode structure. Background Technology

[0002] Titanium-based lead dioxide anodes possess advantages such as excellent conductivity during electrodeposition, high stability in strong acids, light weight, high electrocatalytic activity, strong corrosion resistance, and long service life, making them widely used in the electrodeposition process of non-ferrous metals. However, titanium-based lead dioxide anodes currently experience some deformation during use, affecting electrodeposition performance and cathode product quality. Furthermore, after the anode reaches the end of its service life, it requires repair and regeneration. The disassembly and repair of existing titanium anode structures is complex, reducing labor productivity.

[0003] In the prior art, patent CN110144607A provides a deformation-resistant titanium anode structure and preparation method for hydrometallurgy. This structure lacks corresponding mechanical support when the electrode plate has a large external size, which increases the actual deformation of the electrode plate, leading to short circuits between the anode and cathode and damaging the electrode plate's performance. Patent CN204959056U discloses a striped electrode plate with a pleated structure. While this pleated structure enhances the mechanical properties of the electrode plate, it also causes uneven current distribution on the electrode plate surface, reducing the electrode plate's efficiency and creating stress concentration points inside the electrode plate, leading to electrode plate damage. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clamp-type titanium-based composite anode structure, which can effectively improve the deformation resistance of the electrode plate, realize modular design, and make the process of repair and regeneration simpler and more convenient.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a clamp-type titanium-based composite anode structure, the composite anode structure including a composite conductive beam, a conductive connecting plate, a titanium mesh, a titanium structural frame, and titanium bolts; the composite conductive beam is connected to the conductive connecting plate, and the conductive connecting plate is connected to the titanium mesh; there are two titanium structural frames, and the titanium structural frames are provided with a plurality of bolt holes; the titanium bolts pass through the bolt holes to clamp and fix the titanium mesh between the two titanium structural frames; the top of the titanium structural frame is connected to the composite conductive beam and the conductive connecting plate.

[0006] Furthermore, the composite conductive beam is made of titanium-clad copper or titanium-clad lead, and is used to conduct large currents.

[0007] Furthermore, the conductive connecting plate is made of titanium or titanium alloy sheet; the thickness of the conductive connecting plate ranges from 3 to 10 mm; the conductive connecting plate is connected to the composite conductive beam by welding, and the conductive connecting plate is connected to the titanium mesh by welding or titanium bolts.

[0008] Furthermore, the titanium structural frame is made of titanium or titanium alloy sheet, and the titanium structural frame is manufactured by welding titanium strips or by integral laser cutting.

[0009] Furthermore, the thickness of the titanium structural frame ranges from 3 to 10 mm; the number of bolt holes in the titanium structural frame ranges from 3 to 25.

[0010] Furthermore, the titanium structural frame includes an outer frame body and a number of intermediate ribs disposed within the frame body; the number of intermediate ribs in the titanium structural frame is 1 to 5.

[0011] Furthermore, the titanium mesh has a titanium-based composite coating structure, which mainly consists of an intermediate layer and an active layer. The intermediate layer is a coating of tin-antimony oxide, titanium nitride, or noble metal oxide, and the active layer is an active layer mainly composed of lead dioxide.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, the clamp-type titanium-based composite anode structure provided by this utility model reduces the bending deformation of the titanium mesh by clamping and fixing the titanium mesh with two titanium structural frames through the clamp-type structure; avoids voltage increase or short circuit caused by titanium mesh deformation during electrolysis; and reduces the disassembly cost of reusing structural components.
