Description

Technical Field

[0001] This utility model relates to the field of electrolytic copper foil technology, specifically to an electrolyte supply system for an electrolytic copper foil machine. Background Technology

[0002] During copper foil electrolysis, the anode tank is connected to the electrolyte supply system, which includes an additive supply module (several additive preparation tanks) and an electrolyte stock solution supply module (electrolyte low-level tank). The electrolyte and additives are mixed and enter the secondary filtration module (several precision filters) to the electrolyte high-level tank (prepared electrolyte storage tank). The electrolyte high-level tank supplies electrolyte to the anode tank of the copper foil electrolysis machine through valves. The current electrolyte supply system involves feeding additives from several additive preparation tanks into the low-level electrolyte tank, then filtering them together through a diatomaceous earth plate filter, followed by a secondary filtration module, and finally into the high-level electrolyte tank. This process results in different additives undergoing multiple filtrations, leading to increased additive consumption. Furthermore, the concentration of additives in the prepared electrolyte is affected by the electrolyte level and temperature in the low-level electrolyte tank, causing side reactions within the electrolyte.

[0003] Therefore, in order to correct the above-mentioned defects, we propose an electrolyte supply system for an electrolytic copper foil machine. Utility Model Content

[0004] This invention addresses the technical problem of providing an electrolyte supply system for an electrolytic copper foil machine. This system optimizes the addition location of additives to achieve optimal product quality, highest production efficiency, and lowest production cost. It involves systematic scientific research and process improvement on the addition point, timing, sequence, speed, mixing method, and selection and design of addition equipment for additives (such as catalysts, auxiliaries, modifiers, nutrient fortifiers, and preservatives). This ensures that additives achieve rapid, uniform, and precise distribution and reaction within the main material, avoiding side reactions, quality defects, and efficiency reduction caused by excessively high or low local concentrations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrolyte supply system for an electrolytic copper foil machine, comprising an additive supply module, a low-level electrolyte tank, a high-level electrolyte tank, a secondary filtration module, and a diatomaceous earth plate filter, and further comprising a conveying pipeline three. The outlet end of the low-level electrolyte tank is connected to the inlet of the diatomaceous earth plate filter. The outlet end of the additive supply module, the outlet end of the diatomaceous earth plate filter, and the inlet end of the conveying pipeline three are connected by a three-way pipe. The inlet end of the secondary filtration module is connected to the conveying pipeline three, and the outlet end of the secondary filtration module is connected to the high-level electrolyte tank. After the additive and the original electrolyte are combined and processed by the secondary filtration module, they enter the high-level electrolyte tank. The high-level electrolyte tank is connected to the anode tank of the electrolytic copper foil machine through a valve.

[0006] Furthermore, the secondary filtration module includes several precision filters that are respectively connected to the conveying pipeline. The drain port of the precision filter is connected to the plate heat exchanger, the drain port of the plate heat exchanger is connected to the high-level electrolyte tank, and the return port of the precision filter is connected to the low-level electrolyte tank through a pipeline.

[0007] Furthermore, the overflow port of the anode tank is connected to the electrolyte low-level tank via a pipe.

[0008] Furthermore, the additive supply module includes several preparation tanks, a first conveying pipeline, and a second conveying pipeline. The outlet end of each of the several preparation tanks is equipped with a peristaltic pump. Each peristaltic pump is connected to the first conveying pipeline via a pipeline. The first conveying pipeline is connected to the second conveying pipeline, and the outlet end of the second conveying pipeline is connected to a tee pipe.

[0009] Furthermore, a pneumatic diaphragm pump is installed on the second conveying pipeline.

[0010] Furthermore, a buffer tank, a flow meter, and a shut-off valve are also installed on the second conveying pipeline. The buffer tank, the pneumatic diaphragm pump, the flow meter, and the shut-off valve are connected in series through the second conveying pipeline.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model combines the additive with the electrolyte stock solution after preliminary filtration and then enters the secondary filtration module. This reduces the filtration path and number of times the additive is filtered, thereby reducing the consumption and amount of additive. The concentration of the additive in the prepared electrolyte is not affected by the liquid level and temperature of the electrolyte tank, ensuring that the additive can achieve rapid, uniform and precise distribution and reaction in the main material, avoiding side reactions, quality defects and efficiency reduction caused by excessively high or low local concentrations.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] This utility model provides a technical solution: like Figure 1 As shown, an electrolyte supply system for an electrolytic copper foil machine optimizes the addition location of additives to achieve the best product quality, highest production efficiency, and lowest production cost. This system involves systematic scientific research and process improvement on the addition points, timing, sequence, speed, mixing methods, and selection and design of addition equipment for additives (such as catalysts, auxiliaries, modifiers, nutrient fortifiers, and preservatives). It ensures that additives achieve rapid, uniform, and precise distribution and reaction in the main material, avoiding side reactions, quality defects, and efficiency reduction caused by excessively high or low local concentrations. Specifically: The system includes an additive supply module, an electrolyte low-level tank 11, an electrolyte high-level tank 9, a secondary filtration module, a diatomaceous earth plate filter 12, and a conveying pipeline 13. The above parts are basically the same as the electrolyte supply system in the prior art. The difference is that the supply line of the additive has been adjusted. The additive no longer enters the electrolyte low-level tank 11 and no longer undergoes preliminary filtration through the diatomaceous earth plate filter 12 after premixing with the electrolyte raw solution. Only the electrolyte raw solution undergoes preliminary filtration through the diatomaceous earth plate filter 12. Specifically, the outlet end of the electrolyte low-level tank 11 is connected to the inlet of the diatomaceous earth plate filter 12. The outlet end of the additive supply module, the outlet end of the diatomaceous earth plate filter 12, and the inlet end of the conveying pipeline 3 13 are connected by a three-way pipe. The inlet end of the secondary filtration module is connected to the conveying pipeline 3 13. The outlet of the secondary filtration module is connected to the electrolyte high-level tank 9. After the additive and the electrolyte concentrate are combined and processed by the secondary filtration module, they enter the electrolyte high-level tank 9. The electrolyte high-level tank 9 is connected to the anode tank 10 of the electrolytic copper foil machine through a valve. This part is basically the same as the electrolyte supply system in the prior art.

[0015] The secondary filtration module includes several precision filters 7 connected to the conveying pipeline 13. The drain port of the precision filter 7 is connected to the plate heat exchanger 8, the drain port of the plate heat exchanger 8 is connected to the high-level electrolyte tank 9, and the return port of the precision filter 7 is connected to the low-level electrolyte tank 11 through a pipeline. This part is basically the same as the electrolyte supply system in the prior art.

[0016] The overflow port of the anode tank 10 is connected to the electrolyte low-level tank 11 through a pipe, which is basically the same as the electrolyte supply system in the prior art.

[0017] The additive supply module includes several preparation tanks 1, a first conveying pipe 3, and a second conveying pipe 4. The outlet end of each preparation tank 1 is equipped with a peristaltic pump 2. Each peristaltic pump 2 is connected to the first conveying pipe 3 through a pipe. The first conveying pipe 3 is connected to the second conveying pipe 4. The outlet end of the second conveying pipe 4 is connected to a tee pipe.

[0018] Among them, a pneumatic diaphragm pump 6 is installed on the second conveying pipeline 4, and a buffer tank 5, a flow meter, and a shut-off valve are also installed on the second conveying pipeline 4. The buffer tank 5, the pneumatic diaphragm pump 6, the flow meter, and the shut-off valve are connected in series through the second conveying pipeline 4.

[0019] In the above process, several preparation tanks 1 contain different additives (such as weighed A, B, C, and D agents of corresponding dosages, and the weighed additives are placed into the corresponding preparation tanks for stirring). The different additives are each fed into the first delivery pipe 3 via peristaltic pump 2 (the flow rate of peristaltic pump 2 is adjusted according to the actual dosage of the additives), and then enter the second delivery pipe 4 together. They then come out of the second delivery pipe 4 and merge with the electrolyte stock solution coming out of the diatomaceous earth plate filter 12, and enter the third delivery pipe 13 together. Then, they are diverted to multiple precision filters 7 for filtration. The electrolyte filtered by the multiple precision filters 7 enters the plate heat exchanger 8 for heat exchange treatment and then enters the high-level electrolyte tank 9. The electrolyte after electrolysis flows back to the low-level tank for recycling through the overflow port of the anode tank 10.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
