Description

Technical Field

[0001] The utility model relates to the field of anode plate equipment, in particular to a double-sided mesh titanium-based lead dioxide anode plate. Background Art

[0002] Titanium-based lead dioxide anodes are unique electrode materials with many significant advantages. They also possess excellent chemical resistance, a high oxygen overpotential, strong oxidizing capacity during electrolysis in aqueous solutions, and a high current density. Consequently, they are widely used in electroplating, hydrometallurgy, wastewater treatment, and cathodic corrosion protection. Overall, titanium-based lead dioxide anodes are highly efficient, environmentally friendly, and durable electrode materials that have replaced traditional electrode materials in many industrial fields.

[0003] The existing diamond-shaped vertical mesh is thin and the structures on both sides of the mesh are inconsistent, resulting in inconsistent deformation resistance under electric field force. During use, there are problems such as large local stress and bulging of the mesh surface, which can easily cause the active layer to fall off and fail. After the active layer falls off, it needs to be repaired and reused to reduce costs and energy consumption. At present, the components of titanium-based lead dioxide anodes are welded together, and disassembly and repair are complicated. The titanium material is easily damaged during the disassembly process. Therefore, how to improve the deformation resistance of the titanium mesh while simplifying the repair process to increase the reuse rate of the titanium substrate is an important development direction of titanium-based lead dioxide anode plates.

[0004] Therefore, a double-sided mesh titanium-based lead dioxide anode plate is needed to assist in solving this problem. Utility Model Content

During use, there are problems such as large local stress and bulging of the mesh surface, which can easily cause the active layer to fall off and fail. After the active layer falls off, it needs to be repaired and reused to reduce costs and energy consumption. At present, the components of the titanium-based lead dioxide anode are welded together, and disassembly and repair are complicated.

The titanium-copper conductive connector is installed between the upper end of the lead dioxide anode plate body and the titanium-copper conductive rod. Titanium transverse ribs with threads at both ends are inserted parallel to the interior of the lead dioxide anode plate body and are spot-welded and fixed. The two ends of the titanium transverse ribs are connected to the titanium fixed edge strips on both sides using titanium fixing nuts.

[0007] The utility model is further configured such that the mesh structure of the titanium double-sided mesh of the lead dioxide anode plate main body can be a double-sided arched mesh or a double-sided trapezoidal mesh with alternating positive and negative directions, a lead dioxide multi-component composite active layer is electrochemically co-deposited on the mesh surface, and the mesh plate thickness satisfies the requirement that the titanium transverse ribs pass through the inner hole and are fixed by spot welding.

[0021] A double-sided mesh titanium-based lead dioxide anode plate, such as Figure 1 - Figure 4 As shown, it includes a lead dioxide anode plate body 1, a titanium fixed edge strip 2, a titanium transverse rib 3, a titanium-copper conductive connector 8 and a titanium-copper conductive rod 10. A blank edge 1-1 is reserved along the upper edge of the base of the lead dioxide anode plate body 1 and is provided with a mounting hole. A titanium-copper conductive connector 8 is installed between the mounting hole and the titanium-copper conductive rod 10. Titanium transverse ribs 3 with threads at both ends are inserted parallel to the inside of the lead dioxide anode plate body 1 and are spot-welded. Titanium transverse ribs 3 at both ends are connected to the titanium fixed edge strips 2 on both sides using titanium fixing nuts 4. The titanium fixed edge strips 2 on both sides are connected to the titanium-copper conductive rod 10 by bolts and welding, respectively.

[0022] Furthermore, the mesh structure of the titanium double-sided mesh 1-2 of the lead dioxide anode plate main body 1 is a double-sided arched mesh or a double-sided trapezoidal mesh that alternates between positive and negative directions. The lead dioxide active layer 1-3 is electrochemically co-deposited on the mesh surface. The lead dioxide active layer 1-3 is a multi-component composite active layer. The mesh thickness satisfies the requirement that the titanium transverse ribs 3 pass through the inner hole and are fixed by spot welding. By setting the titanium double-sided mesh 1-2 of the lead dioxide anode plate main body 1 into a double-sided arched mesh or a double-sided trapezoidal mesh, the mesh thickness is increased compared to the existing flat diamond vertical mesh, the anode surface area is increased, the deformation resistance is improved, and the anode life is extended. Five mounting holes are provided on the titanium reserved blank edge 1-1 on the upper edge of the base of the lead dioxide anode plate main body 1 when the mesh is punched.

[0023] Furthermore, five threaded holes are opened at equal intervals on the bottom surface of the titanium-copper conductive rod 10, which are threadedly connected to the upper end of the titanium-copper conductive connector 8. The connection port is padded with a fluororubber protective pad 7. The lower end of the titanium-copper conductive connector 8 is a flat head with a U-shaped groove in the middle. The U-shaped groove and the mounting hole of the titanium reserved blank edge 1-1 are connected using a titanium fixing bolt 9. The titanium fixing bolt 9 includes a titanium gasket 9-1, a titanium connecting bolt 9-2, and a titanium nut 9-3 for connection. The edge is sealed with corrosion-resistant rubber to prevent copper corrosion.

[0024] Furthermore, a transition connection groove 5 is welded on one side of the titanium-copper conductive rod 10, and the transition connection groove 5 is connected to the titanium fixed edge strip 2 using three sets of titanium positioning bolts 6 in the same straight line, and the titanium fixed edge strip 2 on the other side is directly welded to the titanium-copper conductive rod 10.

[0025] The working principle of the present invention is as follows: when disassembling and repairing, first remove the three sets of titanium positioning bolts 6 and three titanium fixing nuts 4 on the left side of the lead dioxide anode plate main body 1, then remove the left titanium fixing edge strip 2, and then remove the three titanium fixing nuts 4 on the right side and the five sets of titanium fixing bolts 9 on the upper side, so as to realize the disassembly of the lead dioxide titanium anode plate main body 1, and then remake the lead dioxide active layer 1-3 after processing the titanium double-sided mesh 1-2.
