Description

Technical Field

[0001] This utility model relates to the field of electrolytic copper foil machine technology, specifically to a structure for preventing valve core crystallization in an electrolytic copper foil machine. Background Technology

[0002] The main pipe of the electrolytic copper foil machine is equipped with a discharge valve and a drain valve. These valves are usually normally closed and are only opened to release liquid during periodic maintenance of the equipment. Therefore, when the equipment is working normally, the valves are normally closed and the copper sulfate liquid in the upper part is stagnant. Because the copper sulfate solution is stagnant for a long time without flow, and the temperature difference between the inside and outside of the pipeline causes the copper sulfate solution to cool down, crystals will form on the upper part of the valve, causing the pneumatic valve to jam, forming an internal leak, and making it impossible to use normally. This seriously affects automation and also brings problems such as raw material waste, difficulty in personnel maintenance, and leakage of copper sulfate solution. Utility Model Content

[0003] This invention provides a structure for preventing valve core crystallization in an electrolytic copper foil machine, which can solve the problem that the unloading valve and drain valve of the existing electrolytic copper foil machine are prone to jamming due to the static crystallization of copper sulfate solution.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a structure for preventing valve core crystallization in an electrolytic copper foil machine, comprising a main pipe and an inlet pipe connected to the main pipe, wherein the inlet pipe is provided with an inlet port, and a drain valve and a discharge valve are connected to one side of the main pipe, and the pipes connecting the drain valve and the discharge valve to the main pipe are respectively connected to the inlet pipe with a first flushing pipe and a second flushing pipe. By setting the first flushing pipe and the second flushing pipe, when liquid enters the inlet pipe, the liquid can continuously impact the position of the drain valve and the discharge valve and enter the main pipe to form a circulation, preventing the copper sulfate solution from remaining still and crystallizing at the valve core position.

[0005] Preferably, the first flushing pipe and the second flushing pipe are arranged at an angle, so that the copper sulfate solution entering the inlet pipe can smoothly enter the drain valve and the unloading valve.

[0006] Preferably, the lower ends of the first flushing pipe and the second flushing pipe are connected to the drain valve and the unloading valve near the valve core, respectively, which can better prevent the copper sulfate solution from stagnating and crystallizing.

[0007] Preferably, the lower ends of the first flushing pipe and the second flushing pipe are provided with extensions extending in the length direction. The extensions extend into the pipe and the ends are provided with downward-curved guides. The extensions and guides can guide the solution flushed down from the first flushing pipe and the second flushing pipe, so that the solution can vertically impact the valve core and then flow upward into the main pipe to form a circulation.

[0008] Preferably, the two ends of the first flushing pipe and the second flushing pipe are connected and fixed by welding, which can modify the existing pipeline and is relatively low cost.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] By setting up a first flushing pipe and a second flushing pipe, the liquid can continuously impact the positions of the drain valve and unloading valve when the liquid is fed into the inlet pipe, and enter the main pipe to form a circulation. This prevents the copper sulfate solution from stagnating and crystallizing at the valve core position, reduces the downtime failure rate, and improves production efficiency.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] This invention addresses the problem that the unloading valve and drain valve of existing electrolytic copper foil machines easily become stuck due to the static crystallization of copper sulfate solution. Figure 1-2 As shown, the following technical solution is provided: a structure for preventing valve core crystallization in an electrolytic copper foil machine, including a main pipe 7 and an inlet pipe 6 connected to the main pipe 7. The inlet pipe 6 is provided with an inlet port 1. A drain valve 3 and a discharge valve 2 are connected to one side of the main pipe 7. The pipes connecting the drain valve 3 and the discharge valve 2 to the main pipe 7 are respectively connected to a first flushing pipe 5 and a second flushing pipe 4. By setting the first flushing pipe 5 and the second flushing pipe 4, when liquid enters the inlet pipe 6, the liquid can continuously impact the positions of the drain valve 3 and the discharge valve 2 and enter the main pipe 7 to form a circulation, preventing the copper sulfate solution from stagnating and crystallizing at the valve core position.

[0017] Specifically, such as Figure 1As shown, the main pipe 7 and the inlet pipe 6 are arranged parallel to each other. The inlet port 1 is located in the middle of the inlet pipe 6. The solution can move along both sides, enter the main pipe 7 from both ends, and then enter the drain pipe. The drain valve 3 and the unloading valve 2 are installed side by side on the lower side of the main pipe 7, located on both sides of the inlet port 1. Therefore, the solution entering the inlet pipe 6 can flow to both sides and enter the drain valve 3 and the unloading valve 2 along the first flushing pipe 5 and the second flushing pipe 4 respectively. The drain valve 3 and the unloading valve 2 are electrically driven butterfly valves.

[0018] In this embodiment, as Figure 1-2 As shown, the first flushing pipe 5 and the second flushing pipe 4 are arranged at an angle, so that the copper sulfate solution entering the inlet pipe 6 can smoothly enter the drain valve 3 and the unloading valve 2. At the same time, the lower ends of the first flushing pipe 5 and the second flushing pipe 4 are respectively connected to the drain valve 3 and the unloading valve 2 near the valve core 9, which can better prevent the copper sulfate solution from stagnating and crystallizing.

[0019] In this embodiment, as Figure 2 As shown, the lower ends of the first flushing pipe 5 and the second flushing pipe 4 are provided with extensions 8 extending in the length direction. The extensions 8 extend into the pipeline and are provided with downward-curving guides at their ends. The extensions 8 and the guides can guide the solution flushed down from the first flushing pipe 5 and the second flushing pipe 4, so that the solution can vertically impact the valve core 9 and then flow upward into the main pipe 7 to form a circulation. The extensions 8 can extend to the middle of the pipeline where the drain valve 3 and the unloading valve 2 are located. As long as there is solution entering the inlet 1, there will be circulating flow on the upper side of the valve core of the drain valve 3 and the unloading valve 2. There will be no stagnant solution on the upper side of the valve core, so crystallization will not occur.

[0020] In this embodiment, the two ends of the first flushing pipe 5 and the second flushing pipe 4 are connected and fixed by welding. Holes can be made on the side wall of the pipeline where the inlet pipe 6, the drain valve 3, and the unloading valve 2 are located. The two ends of the first flushing pipe 5 and the second flushing pipe 4 can be inserted into the corresponding holes and welded. This is very convenient, can modify existing pipelines, and has a relatively low cost.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0022] Furthermore, in this utility model, descriptions involving terms such as "primary," "secondary," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "primary" or "secondary" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
