Description

Technical Field

[0001] This utility model relates to the field of electrolytic copper foil technology, specifically to a novel energy-saving device for titanium anode plates. Background Technology

[0002] In the production of electrolytic copper foil, the titanium anode plate plays a crucial role, with its conductivity, electrochemical capability, and insolubility being particularly critical. The anode plate is an essential component of the circuit, connected to the positive terminal of an external DC power supply. It guides current into the electrolyte, creating the necessary electric field between the anode plate surface and the cathode to drive the electrolytic reaction. For modern high-quality copper foil production, insoluble anodes are generally used. While soluble copper anodes may have been used in earlier or specific processes, this leads to problems such as anode dissolution, impurities entering the electrolyte, and uneven thickness. Modern high-performance copper foil production rarely uses these anodes. Therefore, high-performance, long-life, and well-designed titanium-based noble metal oxide coated anodes are indispensable key components in the production of modern electrolytic copper foil, especially high-performance ultra-thin copper foil for lithium batteries and low-roughness copper foil for high-frequency, high-speed circuit boards.

[0003] For replaceable titanium anode arrays, the conductivity and electrochemical performance are inextricably linked to product quality and production energy consumption. To reduce energy consumption during electrolysis, this invention presents a novel energy-saving device for titanium anode plates, which improves electroplating efficiency, reduces energy loss, and enhances energy utilization at low cost. Summary of the Invention

[0004] This invention proposes a novel energy-saving device for titanium anode plates, which solves the energy consumption problems in related technologies.

[0005] The technical solution of this utility model is as follows: A novel energy-saving device for titanium anode plates includes a titanium anode plate, an anode groove, and a thick titanium plate. The thick titanium plate is disposed between the titanium anode plate and the anode groove. The thickness of the thick titanium plate is 2mm. The thick titanium plate is provided with multiple through holes corresponding to the titanium anode plate. The thick titanium plate is fixed between the titanium anode plate and the anode groove by studs and bolts.

[0006] Preferably, the length, width, and hole positions of the thick titanium plate are adapted to the titanium anode plate.

[0007] Preferably, the material of the thick titanium plate is TA1 titanium.

[0008] Preferably, each device comprises 24 of the 2mm thick titanium plates.

[0009] Preferably, the edges of the thick titanium plate are free of burrs and flash.

[0010] Preferably, the dimensional tolerances of the thick titanium plate are: length and width tolerances of ±0.20 mm, and thickness tolerances of (0, +0.30) mm.

[0011] The working principle and beneficial effects of this utility model are as follows: This device successfully reduces the electrode spacing by adding a 2mm titanium plate between the original titanium anode plate and the titanium anode tank. The reduced distance shortens the migration path of ions, significantly lowering electrolyte resistance. The shorter electrode distance also results in a more uniform electric field distribution on the cathode surface. This means reduced current density differences between different points on the cathode surface, leading to fewer side reactions and a lower proportion of side reactions across the entire cathode surface, thus improving quality. By reasonably reducing the distance between the cathode and anode while keeping the current constant, improving current distribution uniformity and reducing concentration polarization effectively suppresses side reactions such as hydrogen evolution, thereby increasing electroplating current efficiency and reducing production costs. Therefore, this new titanium anode plate energy-saving device can significantly reduce costs and increase efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1 A preferred embodiment of the humidifier with controllable mist output provided by this utility model is, for example... Figures 1 to 2As shown: A novel energy-saving device for titanium anode plates includes a titanium anode plate 2, an anode groove, and a thick titanium plate 1. The thick titanium plate 1 is disposed between the titanium anode plate and the anode groove. The thickness of the thick titanium plate 1 is 2mm. The thick titanium plate 1 has multiple through holes 3 corresponding to the titanium anode plate. The thick titanium plate 1 is fixed between the titanium anode plate 2 and the anode groove by studs and bolts. The length, width, and hole positions of the thick titanium plate 1 are adapted to the titanium anode plate 2. The material of the thick titanium plate 1 is TA1 titanium. Each set of devices includes 24 pieces of 2mm thick titanium plates 1. The edges of the thick titanium plates 1 are free of burrs and flash. The dimensional tolerances of the thick titanium plates 1 are: length and width tolerances of ±0.20mm, and thickness tolerances of (0, +0.30)mm.

[0017] In this embodiment, during the actual replacement of the anode plate, the titanium anode plate 2 that should have been used on the machine is used in combination with the 2mm thick titanium plate 1. The 2mm thick titanium plate 1 is installed with the stud of the titanium anode plate 2 as a reference, and the 2mm thick titanium plate 1 is clamped between the titanium anode plate 1 and the anode groove, and fixed by the stud and bolt.

[0018] Working Principle: The production principle of electrolytic copper foil is to deposit copper ions in the electrolyte onto the cathode roller surface using positive and negative electric fields. Under existing process conditions, factors affecting the production rate include electric field strength. According to Ohm's law, in this device, with a constant current, reducing the distance d between the positive and negative electrodes shortens the migration path of ions in the electrolyte, reduces resistance, and lowers the required voltage under constant current conditions. Furthermore, a smaller electrode distance d results in a more uniform electric field distribution, reducing localized areas of excessive thickness or thinness and effectively improving product yield.

[0019] Results: Over a period of six months, experiments were conducted on selected machines, and relevant data were analyzed. Table 1 below shows the resistance values ​​of the positive and negative terminals of the machine tool under the same current conditions: Table 2 below shows the power consumption of the machine under the same current and time conditions; The data above leads to the conclusion that after using the new titanium anode plate energy-saving device, the machine resistance is significantly reduced, and the power consumption also shows a downward trend. Based on the current electricity price of 0.75 yuan / kWh, each device can reduce power consumption by 156 kWh / day, which is expected to save 117 yuan / day.

[0020] This device successfully reduces the electrode spacing by adding a 2mm titanium plate between the original titanium anode plate and the titanium anode tank. The reduced distance shortens the migration path of ions, significantly lowering electrolyte resistance. The shorter electrode distance also results in a more uniform electric field distribution on the cathode surface. This means reduced current density differences between different points on the cathode surface, leading to fewer side reactions and a lower proportion of side reactions across the entire cathode surface, thus improving quality. By reasonably reducing the distance between the cathode and anode while keeping the current constant, improving current distribution uniformity and reducing concentration polarization effectively suppresses side reactions such as hydrogen evolution, thereby increasing electroplating current efficiency and reducing production costs. Therefore, this new titanium anode plate energy-saving device can significantly reduce costs and increase efficiency.
