Description

Technical Field

[0001] This invention relates to the field of electrolytic copper foil production technology, specifically to a liquid loading mechanism for a foil production machine. Background Technology

[0002] Traditional copper foil feeding systems consist of three parts: a distributor, feeding pipes, and feeding port troughs. The distributor has several feeding ports (typically 10-20), connected to the feeding pipes via flanges, with the other end of the feeding pipe connected to the feeding port trough. Technical solutions in publications CN223063672U, CN216688358U, CN117661045A, and CN115679393A all employ this structure with multiple feeding ports. In operation, this structure allows the electrolyte to be almost directly sprayed into the anode tank through the feeding pipes, resulting in high feeding pressure and a tendency for bubbles to form on the copper foil. Some copper foil manufacturers have considered reducing the diameter of the feeding pipes and increasing the number of feeding pipes to alleviate the feeding pressure. However, this approach increases equipment investment costs and system leakage points, significantly increasing equipment investment and maintenance costs, and in practice, it does not effectively solve the industry-wide problem of copper foil bubble formation. Summary of the Invention

[0003] This invention provides a liquid feeding mechanism for a foil production machine, which can solve the problem in existing foil production machine liquid feeding systems where the electrolyte is directly sprayed into the anode tank through the liquid feeding pipe, resulting in high liquid feeding pressure and easy generation of bubbles in the copper foil.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a liquid feeding mechanism for a foil production machine, comprising: a liquid storage mechanism, wherein a liquid storage chamber is provided inside the liquid storage mechanism, at least one liquid feeding pipe is connected to the side of the liquid storage mechanism, the top of the liquid storage mechanism is connected to the anode tank of the foil production machine, a flow diversion component is installed between the liquid storage mechanism and the anode tank, and the cross-section of the liquid storage mechanism gradually decreases from top to bottom. By setting the liquid storage mechanism with a narrow upper end and a wide lower end, the electrolyte can be effectively buffered, and the flow diversion component at the top can divert the electrolyte, so that the electrolyte enters the anode tank evenly, thereby reducing the risk of copper foil cross-bubbling and improving product quality.

[0005] Preferably, the liquid storage mechanism is a box-shaped structure with its front and rear side walls inclined inward at the top, forming a typical structure that is narrow at the top and wide at the bottom, resulting in good buffering effect.

[0006] Preferably, the upper end of the liquid storage mechanism is connected to a square box connector, and the diversion component is installed inside the square box connector. The square box connector facilitates connection with the anode tank and also facilitates the installation and fixation of the diversion component.

[0007] Preferably, the diversion component is a box-shaped structure with an open bottom, including a box body. The top surface of the box body is herringbone-shaped, and a diversion rib is provided in the middle of the top surface. Liquid outlet grooves are provided on both sides of the diversion rib. After the electrolyte enters the box body, it can be diverted to both sides by the diversion rib and flow out evenly from the liquid outlet grooves. The electrolyte can enter the anode groove evenly.

[0008] Preferably, the cross-section of the diversion rib is an inverted triangle, which has a good diversion effect and is less prone to turbulence.

[0009] Preferably, the outlet tank is elongated and arranged along the length of the diversion component, which facilitates the electrolyte to flow evenly from the outlet tank into the anode tank.

[0010] Preferably, the bottom opening edge of the diversion component is provided with a guide slope, which can guide the electrolyte entering the diversion component and reduce resistance.

[0011] Preferably, the bottom of the square box connector is provided with a first connecting flange, the top of the liquid storage mechanism is provided with a second connecting flange, and a sealing gasket is installed between the first connecting flange and the second connecting flange. The combination of the sealing gasket with the first connecting flange and the second connecting flange can form a better sealing effect.

[0012] Preferably, at least one drain pipe is installed at the bottom of the liquid storage mechanism to facilitate the discharge of residual electrolyte in the liquid storage mechanism.

[0013] Preferably, the bottom surface of the liquid storage mechanism includes a flat plate in the middle and inclined plates on both sides of the flat plate. The drain pipe is installed on the flat plate. The inclined plates can concentrate the residual electrolyte at the position of the flat plate and discharge it from the drain pipe to prevent residue.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By setting up a liquid storage mechanism that is narrow at the top and wide at the bottom, the electrolyte can be effectively buffered. The diversion component at the top can divert the electrolyte, allowing it to enter the anode tank evenly, thereby reducing the risk of copper foil cross-bubbling and improving product quality. The entire device has a simple structure, low cost, and few leakage points, effectively reducing equipment investment costs and subsequent maintenance costs. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] This invention addresses the problem in existing copper foil feeding systems where the electrolyte is directly sprayed into the anode tank through the feeding pipe, resulting in high feeding pressure and easy bubble formation on the copper foil. For example... Figure 1-6 As shown, the following technical solution is provided: a liquid feeding mechanism for a foil production machine, comprising: a liquid storage mechanism 1, wherein the liquid storage mechanism 1 has a liquid storage chamber inside, and at least one liquid feeding pipe 3 is connected to the side of the liquid storage mechanism 1. The top of the liquid storage mechanism 1 is connected to the anode tank of the foil production machine. A diversion component 8 is installed between the liquid storage mechanism 1 and the anode tank. The cross-section of the liquid storage mechanism 1 gradually decreases from top to bottom. By setting the liquid storage mechanism 1 with a narrow top and a wide bottom, the electrolyte can be effectively buffered. The diversion component 8 at the top can divert the electrolyte, so that the electrolyte enters the anode tank evenly, thereby reducing the risk of copper foil cross-bubbling and improving product quality.

[0019] Specifically, the liquid storage mechanism 1 has a box-shaped structure with its front and rear side walls inclined inward at the top, forming a typical structure that is narrow at the top and wide at the bottom, resulting in good buffering effect. Multiple liquid supply pipes 3 are installed on the front or rear side wall of the liquid storage mechanism 1, arranged side by side. Each liquid supply pipe 3 is connected to a liquid supply control valve 2 via a liquid supply pipe connecting flange 10. Multiple liquid supply pipes 3 can supply liquid simultaneously, or the number of liquid supply pipes 3 can be controlled by the liquid supply control valve 2. The diversion component 8 can be installed as an independent component on the upper part of the liquid storage mechanism 1, or it can be integrally formed with the liquid storage mechanism 1 as part of it.

[0020] To facilitate the installation of the diversion component 8 and the connection between the liquid storage mechanism 1 and the anode tank, a square box connector 7 is connected to the upper end of the liquid storage mechanism 1. The diversion component 8 is installed inside the square box connector 7. The square box connector 7 facilitates connection to the anode tank and also facilitates the installation and fixation of the diversion component 8. The two ends of the square box connector 7 are open-ended. Figure 6 As shown, the liquid storage mechanism 1 has a box-shaped sidewall 71 and a first connecting flange 72 located at the bottom of the box-shaped sidewall 71. A second connecting flange 14 is provided on the top of the liquid storage mechanism 1. A sealing gasket 6 is installed between the first connecting flange 72 and the second connecting flange 14. The combination of the sealing gasket 6 with the first connecting flange 72 and the second connecting flange 14 can form a better sealing effect.

[0021] As a specific embodiment of the diversion component 8, such as Figure 4-5 As shown, the diversion component 8 is a box-shaped structure with an open bottom, including a box body 81. The top surface 84 of the box body 81 is herringbone-shaped, and a diversion rib 83 is provided in the middle of the top surface 84. Liquid outlet grooves 82 are provided on both sides of the diversion rib 83. After the electrolyte enters the box body 81, it can be diverted to both sides by the diversion rib 83 and flows out evenly from the liquid outlet grooves 82, allowing the electrolyte to enter the anode tank evenly. The diversion rib 83 has an inverted triangular cross-section, resulting in good diversion effect and reducing the likelihood of turbulence.

[0022] The outlet tank 82 is elongated and arranged along the length of the diversion component 8, which facilitates the uniform flow of electrolyte from the outlet tank 82 into the anode tank. Simultaneously, a guide slope 85 is provided at the edge of the bottom opening of the diversion component 8 to guide the electrolyte entering the diversion component 8 and reduce resistance.

[0023] In this embodiment, at least one drain pipe 5 is installed at the bottom of the liquid storage mechanism 1 to facilitate the discharge of residual electrolyte in the liquid storage mechanism 1. Specifically, as shown in the figure... Figure 1-2 As shown, two drain pipes 5 can be installed side by side at the bottom of the liquid storage mechanism 1. The lower end of the drain pipe 5 is connected to the drain control valve 4 through a drain connection flange 9. The drain control valve 4 can control whether the electrolyte inside the liquid storage mechanism 1 is discharged. Specifically, the bottom surface of the liquid storage mechanism 1 includes a flat plate 12 in the middle and inclined plates 11 on both sides of the flat plate 12. The drain pipe 5 is installed on the flat plate 12. The inclined plates 11 can concentrate the residual electrolyte at the position of the flat plate 12 and discharge it from the drain pipe 5 to prevent residue.

[0024] In this embodiment, the liquid storage mechanism 1 is box-shaped, 1500mm long, 400mm wide at the bottom, and 300mm wide at the top. The front and rear side walls are inclined at a 25° angle. It is made of 304 stainless steel (5mm thick), which is corrosion-resistant and meets strength requirements. The central plate 12 of the bottom structure is 800mm long and 400mm wide, with inclined plates 11 on both sides at a 25° angle to ensure that accumulated liquid is concentrated on the plate. A second connecting flange 14 is provided at the top of the liquid storage mechanism 1, with dimensions matching the square box connector. The flange is 10mm thick and has 16 bolt holes.

[0025] Quantity of liquid inlet pipes 3: Three pipes are installed side-by-side on the front wall of the liquid storage mechanism (300mm apart). They are made of DN50 stainless steel pipes (outer diameter 57mm, wall thickness 3mm) and welded to the liquid storage mechanism via liquid inlet pipe connecting flange 10. Control components: Each liquid inlet pipe is equipped with a DN50 ball valve as the liquid inlet control valve 2, which can be individually controlled to control the on / off state and adapt to different flow requirements (total flow rate can be adjusted to 5-15m³ / h).

[0026] Operating procedures: Liquid inlet: Open the liquid inlet control valve 2, and the electrolyte enters the liquid storage mechanism 1 through the liquid inlet pipe 3. Due to the "wide at the bottom and narrow at the top" structure, the flow rate drops from 1.8m / s to 0.4m / s, and the pressure drops from 0.4MPa to 0.08MPa, thus achieving buffering.

[0027] Diversion: The buffered electrolyte rises gently to the square box connector 7, enters the diversion component 8, is guided by the herringbone top surface 84 to the diversion rib 83, and is diverted to the liquid outlet tanks 82 on both sides through the inverted triangular cross section.

[0028] Inlet: The electrolyte flows uniformly into the anode tank from the outlet tank 82 at a flow rate of 0.2 m / s. The flow rate deviation at each point along the length of the anode tank is ≤3%, ensuring stable electrolyte distribution on the copper foil surface and reducing cross-bubbling.

[0029] Sewage discharge: Periodically open the sewage control valve 4. The sediment at the bottom of the liquid storage mechanism is collected with the accumulated liquid through the inclined plate 11 to the flat plate 12 and discharged from the sewage pipe 5 to avoid impurities affecting the purity of the electrolyte.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention 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 indication will also change accordingly.

[0031] Furthermore, in this invention, 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 that feature. In the description of this invention, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" 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 invention according to the specific circumstances.

[0033] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If 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 the present invention.
