Description
Technical Field
[0001] This invention relates to the field of electrode foil technology, and in particular to a formation apparatus and method for a high-temperature resistant and anti-interference electrode foil for photovoltaic power plants. Background Technology
[0002] For example, the patent application with publication number CN112185716A, entitled "This invention relates to the field of electrode foil production technology," discloses an electrode foil formation device. This application design solves the problem of poor uniformity caused by substandard concentration of formation liquid in a certain area of the formation tank, and also avoids the problem of poor removal effect of formation liquid adhering to the surface of the guide roller, which affects the appearance quality of the electrode foil product.
[0003] The aforementioned cross-contamination of the forming solution between different forming pools leads to poor stability of each stage of the forming process. Furthermore, the residual moisture on the electrode foil surface after cleaning affects the concentration of the subsequent forming solution and the quality of the oxide film formation. Moreover, the aforementioned applications lack online detection methods, making it impossible to monitor the oxide film quality in real time and ensuring product quality consistency. Therefore, this application provides a forming device and method for high-temperature resistant and anti-interference electrode foil for photovoltaic power plants to meet the requirements. Summary of the Invention
[0004] The purpose of this application is to provide a formation apparatus and method for high-temperature resistant and anti-interference electrode foil for photovoltaic power plants, which can effectively solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides the following technical solution: a formation apparatus for high-temperature resistant and anti-interference electrode foil for photovoltaic power plants, comprising:
[0006] A formation cell, wherein multiple formation cells are arranged in sequence, and an electrode foil is continuously conveyed inside the formation cell;
[0007] The electrode mechanism includes two sets of positive electrode components and negative electrode components, which are respectively disposed inside each of the formation cells, and are used to apply a formation voltage to the electrode foil.
[0008] An intermediate processing unit is provided in the transition area between two adjacent formation cells, and is used to clean the formation liquid remaining on the surface of the electrode foil output from the previous formation cell;
[0009] A drying unit is disposed above the intermediate processing mechanism and is used to dry the surface of the electrode foil after it has been cleaned by the intermediate processing mechanism.
[0010] The testing mechanism is installed in the upper region of the formation tank and is used to perform real-time quality testing on the oxide film layer on the surface of the electrode foil after it has been processed by the drying unit.
[0011] The electrode mechanism includes two symmetrically arranged support frames, which are fixedly installed on both sides of the upper end of the formation tank. Ceramic insulating support components are fixedly installed on the inner bottom of the two support frames respectively, and the two ceramic insulating support components are supported by an insulating support roller through a bearing.
[0012] A conductive cylinder is coaxially sleeved on the outer peripheral surface of the insulating support roller, and the conductive cylinder forms electrical contact with the surface of the electrode foil. Leakage monitoring devices are respectively provided at both ends of the shaft of the insulating support roller.
[0013] A conductive contact brush is provided on the inner wall of the support frame and above the ceramic insulating support. The conductive contact brush maintains sliding electrical contact with the end of the conductive cylinder and is used to conduct voltage to the conductive cylinder.
[0014] The intermediate processing mechanism includes a cleaning chamber, which is fixedly installed at the connection position between two adjacent formation tanks. A guide roller is rotatably installed at the bottom of the inner cavity of the cleaning chamber, and the electrode foil is wound around the outer surface of the guide roller in an S-shaped path.
[0015] An ultrasonic oscillator is fixedly installed in the middle of the inner cavity of the cleaning chamber. The ultrasonic oscillator generates a cavitation effect in the cleaning medium through high-frequency mechanical vibration, which initially peels off the formation liquid adhering to the surface of the electrode foil.
[0016] The bottom of the inner cavity of the cleaning chamber is fixedly provided with a bubble cleaning shell. The bubble cleaning shell has a U-shaped groove structure, and the opening end of the bubble cleaning shell faces upward and is directly opposite the conveying plane of the electrode foil. During the conveying process, the electrode foil passes through the U-shaped opening of the bubble cleaning shell, so that the lower surface of the electrode foil and the bubble cleaning shell form a relative cleaning space.
[0017] The inner wall of the bubble cleaning shell is evenly distributed with multiple micro-hole nozzles, and a gas distribution core is coaxially arranged in the center of the bubble cleaning shell. The upper end of the gas distribution core is evenly opened with multiple airflow guide holes along the circumference to evenly disperse the input gas.
[0018] An airflow guide plate is fixedly connected to the upper end of the gas distribution core cylinder. The inclination angle of the airflow guide plate is 30°-45°, which is used to guide the dispersed gas to the surface of the electrode foil. One end of the gas distribution core cylinder is connected to a gas supply pipe.
[0019] The drying unit includes a first air shell and a second air shell, which are respectively disposed on both sides of the electrode foil. Both the first air shell and the second air shell are provided with air guide plates inside. The air guide plates have an arc-shaped structure and are used to uniformly guide the input airflow to the surface of the electrode foil.
[0020] The air inlet ends of the first and second air casings are connected to each other through a manifold, and the manifold and the vent pipe are respectively connected to different output ports of the same external air supply system.
[0021] The detection mechanism includes two symmetrically arranged mounting seats, which are fixedly installed on the upper end of the formation tank, and an insulating detection roller is rotatably supported between the two mounting seats.
[0022] The outer circumferential surface of the insulating test roller is provided with a test mounting groove along the axial direction. An elastic buffer pad is fixedly bonded to the bottom of the test mounting groove. The elastic buffer pad is made of silicone rubber.
[0023] The upper surface of the elastic buffer pad is detachably equipped with a voltage detection probe. The detection end face of the voltage detection probe is covered with a conductive copper foil layer. Both ends of the voltage detection probe extend through the side wall of the insulating detection roller to form an electrical connection ring. The electrical connection ring is electrically connected to an external detection power supply and data acquisition system through wires.
[0024] This invention also provides a method for forming high-temperature resistant and interference-resistant electrode foil for photovoltaic power plants.
[0025] Step 1: The electrode foil is continuously conveyed through multiple formation cells. The electrode mechanism in each formation cell applies a progressively increasing formation voltage according to process requirements to perform graded electrochemical oxidation treatment on the electrode foil.
[0026] Step 2: Before the electrode foil treated in the primary formation cell enters the adjacent secondary formation cell, it undergoes surface treatment through an intermediate treatment mechanism. The intermediate treatment mechanism removes the primary formation solution remaining on the surface of the electrode foil through ultrasonic vibration and gas-liquid mixing rinsing, thus avoiding cross-contamination between different formation solutions.
[0027] Step 3: After being cleaned by the intermediate processing unit, the electrode foil undergoes surface drying treatment in the drying unit to remove surface moisture. Subsequently, the testing unit performs real-time voltage detection on the oxide film layer on the surface of the dried electrode foil to obtain film thickness distribution data, evaluate the quality status of the current formation stage, and dynamically adjust the subsequent formation process parameters based on the test results.
[0028] In summary, the technical effects and advantages of this invention are as follows:
[0029] 1. Before entering the adjacent secondary formation tank, the electrode foil treated in the primary formation tank of this invention undergoes surface treatment through an intermediate processing mechanism. Inside the cleaning chamber, the cavitation effect generated by the ultrasonic oscillator, together with the cleaning liquid sprayed by the bubble cleaning shell through the micro-orifice nozzle and the gas sprayed by the gas distribution core, forms a highly efficient gas-liquid two-phase flow cleaning zone. This thoroughly removes the primary formation liquid remaining on the surface of the electrode foil, avoids cross-contamination of formation liquid between different formation tanks, ensures the independence and stability of each formation process, and lays the foundation for the formation of a high-quality oxide film layer.
[0030] 2. In this invention, the electrode foil, after being cleaned by the intermediate processing unit, undergoes surface drying treatment through the drying unit. Clean hot air is evenly blown onto the surface of the electrode foil through the first and second air shells to achieve rapid drying and ensure that there is no residual moisture on the surface. Subsequently, the detection unit performs real-time voltage detection on the oxide film layer on the surface of the dried electrode foil to obtain film thickness distribution data. This integrated drying and detection design not only ensures the surface cleanliness of the electrode foil before entering the next process, but also realizes online real-time monitoring of the formation quality, providing accurate data support for the dynamic adjustment of process parameters, and significantly improving the consistency of product quality and production efficiency.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0056] Example 1, Reference Figures 1 to 22 The apparatus and method for forming high-temperature resistant and anti-interference electrode foil for photovoltaic power plants shown include a formation tank 1, an electrode mechanism 6, an intermediate processing mechanism 5, a drying unit 3, and a testing mechanism 4.
[0057] Multiple formation cells 1 are arranged in sequence. Each formation cell 1 contains a formation electrolyte of different concentrations and temperatures. The electrode foil 2 is continuously conveyed through each formation cell 1 to form a multi-stage formation process route.
[0058] It is worth noting that the electrode foil 2 is continuously conveyed through multiple formation cells 1. The electrode mechanism 6 in each formation cell 1 applies a progressively increasing formation voltage according to the process requirements to perform graded electrochemical oxidation treatment on the electrode foil 2 to form a dense oxide film layer.
[0059] Before the electrode foil 2, after being treated in the primary formation tank 1, enters the adjacent secondary formation tank 1, it undergoes surface treatment through the intermediate treatment mechanism 5. Inside the cleaning tank 51, the ultrasonic oscillator 53 generates a cavitation effect, and the bubble cleaning shell 54 sprays cleaning liquid through the micro-hole nozzle 57. At the same time, gas is sprayed through the gas distribution core cylinder 58 to form a gas-liquid two-phase flow cleaning area, which thoroughly removes the primary formation liquid remaining on the surface of the electrode foil 2 and avoids cross-contamination between different formation liquids.
[0060] After being cleaned by the intermediate processing unit 5, the electrode foil 2 undergoes surface drying treatment through the drying unit 3. High-temperature clean hot air is evenly blown onto the surface of the electrode foil 2 through the first air shell 31 and the second air shell 33 to remove surface moisture. Subsequently, the detection unit 4 performs real-time voltage detection on the oxide film layer on the surface of the dried electrode foil 2 to obtain film thickness distribution data.
[0061] Example 2: This example provides a further technical solution for the electrode mechanism 6.
[0062] The electrode mechanism 6 includes two sets of positive electrode components and negative electrode components, which are respectively arranged inside each formation cell 1. The electrode mechanism 6 includes two symmetrically arranged support frames 62, and the support frames 62 are fixedly installed on both sides of the upper end of the formation cell 1. Ceramic insulating support components 63 are fixedly installed on the inner bottom of the two support frames 62 respectively. The ceramic insulating support components 63 have excellent corrosion resistance and insulation performance. The two ceramic insulating support components 63 jointly support the installation of an insulating support roller 65 through bearings. The insulating support roller 65 is made of epoxy resin composite material and has high insulation strength and mechanical strength.
[0063] A conductive cylinder 61 is coaxially sleeved on the outer circumferential surface of the insulating support roller 65. The conductive cylinder 61 is made of high-purity aluminum and its surface is precision polished to form good electrical contact with the surface of the electrode foil 2. Leakage monitoring devices 66 are respectively installed at both ends of the shaft of the insulating support roller 65. The leakage monitoring devices 66 monitor the insulation performance in real time and automatically alarm when the leakage current exceeds the safety threshold. A conductive contact brush 64 is installed on the inner wall of the support frame 62 and above the ceramic insulating support 63. The conductive contact brush 64 is made of silver and graphite composite material and maintains sliding electrical contact with the end of the conductive cylinder 61 to conduct the forming voltage to the conductive cylinder 61.
[0064] Among them, the conductive contact brush 64 made of silver and graphite composite material forms a stable sliding electrical contact with the conductive cylinder 61 made of high-purity aluminum material and is precision polished, thus constructing a low-resistance and high-reliability current conduction channel. This electrical path, together with the ceramic insulating support 63 and the epoxy resin insulating support roller 65, forms a double insulation protection to ensure that the current is accurately applied to the surface of the electrode foil 2.
[0065] Meanwhile, the leakage current monitoring device 66 monitors the insulation status of the insulating support roller 65 in real time. When abnormal leakage current is detected in the insulating support roller 65, an alarm is automatically triggered to prevent leakage current from causing fluctuations in the formation voltage of the formation cell 1. This ensures the uniformity and density of the oxide film layer formed on the surface of the electrode foil 2, and improves the formation quality and product consistency of the high-temperature resistant and anti-interference electrode foil used in photovoltaic power plants.
[0066] Implementation 3: This embodiment provides a further technical solution for the intermediate processing mechanism 5.
[0067] The intermediate treatment mechanism 5 is located in the transition area between two adjacent formation tanks 1. Specifically, the intermediate treatment mechanism 5 includes a cleaning tank 51, which is made of acid and alkali resistant engineering plastic and is fixedly installed at the connection position between the two adjacent formation tanks 1. A guide roller shaft 56 is rotatably mounted at the bottom of the inner cavity of the cleaning tank 51. The surface of the guide roller shaft 56 is covered with a polytetrafluoroethylene layer. The electrode foil 2 is wound around the outer surface of the guide roller shaft 56 in an S-shaped path to increase the cleaning contact time and area.
[0068] An ultrasonic oscillator 53 is fixedly installed in the middle of the inner cavity of the cleaning chamber 51. The ultrasonic oscillator 53 operates at a frequency of 28-40kHz. It generates a cavitation effect in the cleaning medium through high-frequency mechanical vibration, which initially peels off the formation liquid adhering to the surface of the electrode foil 2. A bubble cleaning shell 54 is fixedly installed at the bottom of the inner cavity of the cleaning chamber 51. The bubble cleaning shell 54 has a U-shaped groove structure, and the open end of the bubble cleaning shell 54 faces upward and is directly opposite the conveying plane of the electrode foil 2. During the conveying process, the electrode foil 2 passes through the U-shaped opening of the bubble cleaning shell 54, so that a relative cleaning space is formed between the lower surface of the electrode foil 2 and the bubble cleaning shell 54.
[0069] The inner wall of the bubble cleaning shell 54 is evenly distributed with multiple micro-hole nozzles 57. A gas distribution core cylinder 58 is coaxially arranged in the center of the bubble cleaning shell 54. Multiple airflow guide holes 59 are evenly opened in the upper end of the gas distribution core cylinder 58 along the circumference to evenly disperse the input gas. An airflow guide inclined plate 511 is fixedly connected to the upper end of the gas distribution core cylinder 58. The inclination angle of the airflow guide inclined plate 511 is 30°-45° to guide the dispersed gas to the surface of the electrode foil 2. One end of the gas distribution core cylinder 58 is connected to a gas supply pipe 55.
[0070] When the electrode foil 2 enters the cleaning chamber 51, the gas distribution core 58 sprays clean compressed air upwards. The air enters the interior of the bubble cleaning shell 54, and the air inside the bubble cleaning shell 54 is ejected upwards through the micro-orifice nozzle 57, forming a gas-liquid two-phase flow cleaning zone on the surface of the electrode foil 2. The gas-liquid two-phase flow cleaning zone works synergistically with the cavitation effect generated by the ultrasonic oscillator 53 to efficiently and thoroughly remove the formation liquid remaining on the surface of the electrode foil 2.
[0071] It is worth noting that the 28-40kHz high-frequency vibration generated by the ultrasonic oscillator 53 creates a cavitation effect in the cleaning medium, which initially physically peels off the formation liquid adhering to the surface of the electrode foil 2. The U-shaped groove structure of the bubble cleaning shell 54 forms a relatively closed cleaning space with the lower surface of the electrode foil 2. Combined with the uniform airflow distribution of the gas distribution core cylinder 58, the dispersion effect of the airflow guide hole 59, and the airflow guide inclined plate 511 with an inclination angle of 30°-45°, the compressed air is sprayed upward through the micro-orifice nozzle 57 to form a uniform and fine bubble, creating a highly efficient gas-liquid two-phase flow cleaning area on the surface of the electrode foil 2.
[0072] The gas-liquid two-phase flow cleaning zone works synergistically with the ultrasonic cavitation effect. Through multiple mechanisms of bubble impact, liquid scouring and cavitation micro-jet, the residual formation liquid on the surface of electrode foil 2 is efficiently and thoroughly removed, avoiding cross-contamination of formation liquid between different formation pools 1, and ensuring the stability of subsequent formation processes and the consistency of the oxide film quality on the surface of electrode foil 2.
[0073] Example 4 provides a further technical solution for the drying unit 3 and the detection mechanism 4.
[0074] The drying unit 3 is positioned above the intermediate processing mechanism 5. Specifically, the drying unit 3 includes a first air shell 31 and a second air shell 33, which are respectively positioned on the upper and lower sides of the electrode foil 2. The first air shell 31 and the second air shell 33 are made of aluminum alloy and have a hollow internal structure. Both the first air shell 31 and the second air shell 33 have an air guide plate 34 inside. The air guide plate 34 has an arc-shaped structure and a guide groove on its surface, which is used to uniformly guide the input airflow to the surface of the electrode foil 2 and avoid the concentrated impact of the airflow causing deformation of the electrode foil 2.
[0075] The air inlets of the first air housing 31 and the second air housing 33 are interconnected via a manifold 32. The manifold 32 and the air supply pipe 55 are respectively connected to different output ports of the same external air supply system. The external air supply system provides filtered and heated clean air to 60-80°C, which is distributed to the first air housing 31 and the second air housing 33 through the manifold 32 to quickly dry the cleaned electrode foil 2. The drying time is controlled within 2-5 seconds.
[0076] The testing mechanism 4 is installed in the upper region of the formation tank 1. Specifically, the testing mechanism 4 includes two symmetrically arranged mounting seats 41, which are made of insulating engineering plastic and are fixedly installed in the upper part of the formation tank 1. An insulating testing roller 42 is rotatably supported between the two mounting seats 41.
[0077] An axially oriented detection mounting groove 45 is formed on the outer peripheral surface of the insulating detection roller 42. An elastic buffer pad 46 is fixedly bonded to the bottom of the detection mounting groove 45. The elastic buffer pad 46 is made of silicone rubber with a thickness of 2-3 mm, exhibiting good elastic recovery and electrical insulation properties. A voltage detection probe 43 is detachably mounted on the upper surface of the elastic buffer pad 46. The voltage detection probe 43 employs a high-precision voltage sensor, and its detection end face is covered with a conductive copper foil layer, forming good electrical contact with the surface of the electrode foil 2. Both ends of the voltage detection probe 43 extend through the sidewalls of the insulating detection roller 42, forming an electrical connection ring 44. The electrical connection ring 44 is electrically connected to an external detection power supply and data acquisition system via wires, enabling real-time acquisition of voltage distribution data of the oxide film layer on the surface of the electrode foil 2.
[0078] The drying unit 3 adopts a first air shell 31 and a second air shell 33 arranged symmetrically on the top and bottom, and with the internal arc-shaped air guide plate 34 and the guide groove structure, it guides the clean hot air at 60-80℃ to the upper and lower surfaces of the electrode foil 2 evenly, avoiding the deformation of the foil caused by the concentrated impact of the airflow, and achieving rapid and efficient drying within 2-5 seconds, ensuring that there is no residual moisture on the surface of the electrode foil 2.
[0079] Meanwhile, the manifold 32 connects the first air housing 31 and the second air housing 33 to the external air supply system, realizing the rational distribution of airflow and efficient utilization of energy. The detection mechanism 4 uses an insulating engineering plastic mounting base 41 and an insulating detection roller 42 made of polyetheretherketone material, combined with the dual functions of buffering and insulation of the silicone rubber elastic buffer pad 46, to ensure that the voltage detection probe 43 forms a stable and reliable electrical contact with the surface of the electrode foil 2, while avoiding mechanical damage to the foil during the detection process;
[0080] The conductive copper foil layer on the detection end face of the voltage detection probe 43 improves the detection sensitivity. The connection between the electrical connection ring 44 and the external detection system enables real-time acquisition and analysis of the oxide film voltage distribution data. Since both the external detection system and the voltage detection probe 43 are existing technologies, they will not be described in detail here. The organic combination of the drying unit 3 and the detection mechanism 4 not only ensures that the electrode foil 2 is completely dry before entering the next formation process, enabling online real-time monitoring of formation quality, but also provides data support for the dynamic adjustment of process parameters, significantly improving the product consistency and reliability of high-temperature resistant and anti-interference electrode foils used in photovoltaic power plants.
[0081] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
