Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte inlet for raw foil, in particular to a liquid inlet diversion device for a raw foil machine. Background Art

[0002] The production of electrolytic copper foil is a complex and delicate process, encompassing several key steps, including copper dissolving, foil production, surface treatment, cutting, and packaging. The foil production machine is a key piece of equipment in this process. In existing foil production machine designs, a single inlet is located at the bottom of the tank, connected to 12 inlet pipes. These pipes deliver electrolyte to the inlet, from which it is then transported to the electrolytic chamber.

[0003] However, the electrolyte flow rate in existing electrolyte infusion methods is relatively slow. This leads to low electrodeposition efficiency and increased concentration polarization, resulting in defects such as copper-deficient spots and uneven electroplating on the copper foil surface. These defects not only affect the quality of the copper foil but also reduce production efficiency and product qualification rate.

[0004] To improve the problem of slow electrolyte flow, a common approach is to increase the electrolyte flow rate by adjusting the opening of the inlet valve. However, this increases the amount of electrolyte entering the electrolytic chamber per unit time, reducing electrolyte utilization and thus increasing production costs. Utility Model Content

[0005] The purpose of the utility model is to provide a liquid inlet diversion device for a foil production machine. The liquid inlet diversion device for a foil production machine is provided with a liquid inlet diverter at the liquid inlet. Without increasing the flow rate of the electrolyte flowing out of the liquid inlet pipe, the flow rate of the electrolyte flowing into the electrolytic chamber is increased, thereby avoiding low electrodeposition efficiency and increased concentration polarization, which will cause defects such as copper-poor spots and uneven electroplating on the surface of the copper foil, thereby improving the production quality of the copper foil.

[0009] In some embodiments, the liquid inlet diverter includes a diverter plate, and the diverter plate cover is provided on the top of the liquid inlet;

[0010] A plurality of acceleration units are uniformly arranged along the length direction of the liquid inlet, and the acceleration unit comprises at least two acceleration holes, and the two acceleration holes are symmetrically arranged on the flow distribution plate.

[0011] In some embodiments, the cross section of the flow distribution plate is C-shaped.

[0012] In some embodiments, the surface of the flow distribution plate is curved away from the liquid inlet.

[0013] In some embodiments, the flow distribution plate is made of CPVC plate.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] refer to Figure 1-4 A liquid inlet diversion device for a foil machine includes a liquid inlet 2, multiple liquid inlet pipes 3 and a liquid inlet diverter 4. The liquid inlet 2 serves as an entrance for the electrolyte to enter the electrolytic chamber and is arranged at the bottom of the foil machine tank body 1; an electrolytic chamber is arranged in the foil machine tank body 1, and a plurality of anode plates are arranged on the inner wall of the electrolytic chamber. This is a prior art and will not be described in detail here; multiple liquid inlet pipes 3 are evenly arranged along the length direction of the liquid inlet 2, and the liquid inlet pipes 3 are connected to the bottom of the liquid inlet 2 for uniformly introducing the electrolyte into the liquid inlet 2; the liquid inlet diverter 4 is arranged at the top of the liquid inlet 2, which can improve the flow rate and distribution uniformity of the liquid flowing from the liquid inlet pipe 3 to the electrolytic chamber.

[0025] In some embodiments, the liquid inlet diverter 4 includes a diverter plate 41 and multiple acceleration units 42. The diverter plate 41 is covered on the top of the liquid inlet 2. The length and width of the diverter plate 41 match the size of the liquid inlet 2 to achieve relative sealing of the diverter plate 41 to the liquid inlet 2; the multiple acceleration units 42 are evenly arranged along the length direction of the liquid inlet 2, and each acceleration unit 42 includes at least two acceleration holes. The two acceleration holes are symmetrically arranged on the diverter plate 41 to accelerate the flow of electrolyte by reducing the flow channel cross-section.

[0026] In some embodiments, the cross-section of the diverter plate 41 can be C-shaped, and the surface of the diverter plate 41 is curved away from the liquid inlet 2, which can increase the amount of electrolyte at the bottom of the acceleration unit 42 and further increase the flow rate of the electrolyte into the electrolytic chamber through the liquid inlet diverter 4.

[0027] In some embodiments, the diverter plate 41 may be made of CPVC (chlorinated polyvinyl chloride) sheet material. CPVC sheet material has good corrosion resistance and strength and is suitable for electrolysis environment.

[0028] In some embodiments, the diverter plate 41 and the foil machine tank body 1 can be welded into shape, and large-area welding can be completed in a short time, thereby improving welding efficiency and ensuring that the liquid inlet diverter 4 on the foil machine tank body 1 has a stable structure and good sealing.

[0029] In some embodiments, a plurality of limiting grooves 5 are also included, and the plurality of limiting grooves 5 are arranged at equal intervals at the bottom of the liquid inlet 2. The bottom of the limiting groove 5 passes through the foil machine tank body 1, and the top of the limiting groove 5 is connected to the liquid inlet 2. A liquid inlet pipe 3 is inserted into the limiting groove 5 to ensure that the position of the liquid inlet pipe 3 during installation is accurate and stable, so as to ensure the uniformity of liquid inflow at the bottom of the liquid inlet 2.

[0030] The specific working principle is as follows:

[0031] During operation, the electrolyte is fed into multiple liquid inlet pipes 3 through an external pumping system. Since the liquid inlet pipes 3 are evenly distributed along the length of the liquid inlet 2, the electrolyte is initially homogenized. Subsequently, the electrolyte enters the liquid inlet 2 from the liquid inlet pipes 3 and encounters the liquid inlet diverter 4 located at the top. The surface curvature of the diverter plate 41 can increase the amount of electrolyte at the bottom of the acceleration unit 42, while the acceleration holes in the acceleration unit 42 reduce the flow channel area of ​​the electrolyte from the liquid inlet to the electrolytic chamber, forcing the electrolyte to pass through faster and eventually flow into the electrolytic chamber, where an electrolytic reaction occurs. This avoids low electrodeposition efficiency, increased concentration polarization, and defects such as poor copper spots and uneven electroplating on the copper foil surface, thereby improving the production quality of the copper foil.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
