[0002] There are areas with low fluidity in the liquid discharge and sewage discharge pipelines of the liquid supply system of the raw foil machine. During long-term use, the electrolyte inside the valve pipelines is in a non-flowing state. After liquid discharge, the liquid discharge and sewage discharge valves are blocked, resulting in the crystallization of the internal electrolyte and blocking of the pipelines, greatly affecting the production efficiency. Moreover, if personnel open the crystallized and blocked valves, the valves will be deformed or even damaged, affecting the service life of the valves. Content of the Utility Model

[0003] The utility model provides a raw foil machine reflux liquid supply system, which can solve the problems of low fluidity inside the liquid discharge and sewage discharge pipelines of the existing raw foil machine liquid supply system, resulting in the crystallization and blockage of the internal electrolyte in the pipelines.

A sewage discharge valve and a liquid discharge valve are respectively installed on the two valve pipelines, and the sewage discharge valve and the liquid discharge valve are respectively connected to a sewage discharge pipeline and a liquid discharge pipeline; a liquid supply reflux pipeline is arranged on the side wall of the valve pipeline, connecting the side wall of the valve pipeline with the liquid supply main pipeline. By providing a bypass liquid supply reflux pipeline on the side of the valve pipeline, part of the liquid in the liquid supply main pipeline is transported to the valve pipeline through the liquid supply reflux pipeline, so that the electrolyte in the valve pipeline is in a flowing state, reducing and eliminating the crystallization phenomenon, and improving the production efficiency.

[0005] Preferably, the liquid supply main pipeline includes a main pipe and two branch pipes. One end of the main pipe is connected to one end of the two branch pipes, and the other ends of the two branch pipes are both connected to the liquid supply cavity.

The main pipe and the two branch pipes can uniformly and quickly introduce the electrolyte into the liquid supply cavity, and the electrolyte in the two branch pipes can simultaneously enter the corresponding valve pipelines through the liquid supply reflux pipelines, ensuring the fluidity of the electrolyte in the valve pipelines.

[0006] Preferably, the other ends of the two branch pipes are respectively connected to both ends of the liquid supply cavity, and can enter from both ends of the liquid supply cavity simultaneously, which is beneficial to the synchronous and uniform discharge of the electrolyte on the liquid supply sub-pipelines.

[0007] Preferably, the upper liquid return pipeline is obliquely arranged, and its lower end is communicated with the lower side wall of the valve pipeline, so that the electrolyte in the upper liquid main pipeline can flow into the valve pipeline smoothly without additional power.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0018] The present utility model aims to solve the problem that the internal fluidity of the liquid discharge and sewage discharge pipelines in the existing upper liquid system of the copper foil machine is small, resulting in the crystallization and blockage of the internal electrolyte pipeline. As Figure 1-2As shown in the figure, the following technical solution is provided: a raw foil machine reflux liquid supply system, including a liquid supply cavity 8, and liquid supply branch pipes 9 are arranged side by side on the side of the liquid supply cavity 8; a liquid supply main pipe 1 is used to connect the liquid supply cavity 8 with an electrolyte filtration system; it also includes valve pipes 7, two in number and connected to the liquid supply cavity 8, a sewage discharge valve 4 and a liquid discharge valve 3 are respectively installed on the two valve pipes 7, and the sewage discharge valve 4 and the liquid discharge valve 3 are respectively connected to a sewage discharge pipe 5 and a liquid discharge pipe 2; a liquid supply reflux pipe 6 is arranged on the side wall of the valve pipe 7 and connects the side wall of the valve pipe 7 with the liquid supply main pipe 1. By arranging a bypass liquid supply reflux pipe 6 on the side of the valve pipe 7, part of the liquid in the liquid supply main pipe 1 is transported to the valve pipe 7 through the liquid supply reflux pipe 6, so that the electrolyte in the valve pipe 7 is in a flowing state, reducing and eliminating the crystallization phenomenon, and improving production efficiency.

[0019] Specifically, the liquid supply branch pipes 9 are vertically and evenly arranged on the upper side of the liquid supply cavity 8 and are evenly arranged along the length direction of the liquid supply cavity 8. The electrolyte in the liquid supply cavity 8 is evenly divided by the liquid supply branch pipes and then enters the electrolytic cell body. The liquid discharge pipe 2 is connected to the liquid discharge valve 3, and liquid discharge is carried out after the production is completed; when the liquid discharge is almost over, the sewage discharge valve 4 discharges impurities such as crystallization in the pipeline by means of flushing.

[0020] After the electrolyte is filtered by the electrolyte filtration system, it enters the liquid supply cavity 8 through the liquid supply main pipe 1, the liquid supply reflux pipe 6, and the valve pipe 7, and then is evenly transported to the electrolytic cell by the liquid supply branch pipes 9. In a conventional valve pipe 7 during normal production, the internal electrolyte is prone to crystallization when discharging liquid because it does not flow for a long time, resulting in pipeline blockage and affecting production efficiency. Therefore, in this embodiment, part of the electrolyte entering from the liquid supply main pipe 1 will be diverted into the valve pipe 7 through the liquid supply reflux pipe 6 while entering the liquid supply cavity 8, so that the electrolyte in the valve pipe 7 is always in a flowing state.

[0021] In this example, as Figure 1 shown, the liquid supply main pipe 1 includes a main pipe 11 and two branch pipes 12. One end of the main pipe 11 is connected to one end of the two branch pipes 12, and the other ends of the two branch pipes 12 are both connected to the liquid supply cavity 8. The liquid supply reflux pipes 6 on the two valve pipes 7 are respectively connected to the two branch pipes 12. The main pipe 11 and the two branch pipes 12 can uniformly and quickly introduce the electrolyte into the liquid supply cavity 8, and the electrolyte in the two branch pipes 12 can enter the corresponding valve pipes 7 through the liquid supply reflux pipes 6 at the same time, ensuring the fluidity of the electrolyte in the valve pipes 7.

[0022] Among them, the other ends of the two branch pipes 12 are respectively connected to both ends of the liquid supply cavity 8 and can enter from both ends of the liquid supply cavity 8 at the same time, which is conducive to the synchronous and uniform discharge of the electrolyte on the liquid supply branch pipes 9.

[0023] In this embodiment, as an installation method of the liquid feeding and reflux pipeline 6, as Figure 1 shown, the liquid feeding and reflux pipeline 6 is obliquely arranged, and its lower end is communicated with the lower side wall of the valve pipeline 7, so that the electrolyte in the total liquid feeding pipeline 1 can flow into the valve pipeline 7 smoothly without additional power. When the electrolyte enters the lower part, it can flow from the lower part to the upper part inside the valve pipeline 7 of the valve pipeline 7.

[0024] In order to flexibly control the flow of the electrolyte in the liquid feeding and reflux pipeline 6, a regulating valve 61 is installed on the liquid feeding and reflux pipeline 6, which can control the switch of the electrolyte on the liquid feeding and reflux pipeline 6. The control is flexible. The regulating valve 61 can be installed at the upper end of the liquid feeding and reflux pipeline 6. In this way, after the regulating valve 61 is closed, the electrolyte cannot enter the liquid feeding and reflux pipeline 6.

[0025] In this embodiment, a transparent visible part is arranged on the liquid feeding and reflux pipeline 6, which can timely observe the flow condition of the electrolyte inside the liquid feeding and reflux pipeline 6 and reduce and eliminate the phenomenon of crystallization blockage. For example, the transparent visible part is a transparent pipeline 62 installed in the middle of the liquid feeding and reflux pipeline 6, which can observe the flow condition of the electrolyte inside the liquid feeding and reflux pipeline 6 in all directions.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement condition between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, in the present invention, descriptions such as "primary" and "secondary" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "primary" and "secondary" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0028] In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
