Electrolyte supply nozzle device for metal foil forming device

[0001] The present invention relates to an electrolyte supply nozzle device for a metal foil forming device, and more particularly, to an improved electrolyte supply nozzle device for a metal foil forming device that can uniformly discharge an electrolyte into an anode tank under a drum roll.

[0002] Metal foils, such as copper foils, which are several micrometers to several tens of micrometers thick and used in many electrical and chemical products, including secondary batteries, can be manufactured by an electrolytic (or electrolytic) method.

[0003] Figure 1 shows a configuration diagram of a metal foil forming device that forms the metal foil by an electrolytic method.

[0004] Referring to Fig. 1, a metal foil forming device (1) is configured to include a drum roll (2), which is a cathode electrode, and an electrolytic cell (5) that rotatably supports the drum roll (2).

[0005] And the electrolytic cell (5) is provided with a frame (6), a pair of anode bases (18, 19), a plurality of support beams (15), a pair of current buses (21), and an electrolyte supply nozzle (25).

[0006] In addition, the frame (6) has a front wall and a back wall (not shown) that rotatably support a rotating shaft (not shown) of a drum roll (2), a left wall (7) and a right wall (8) that are erected on the left and right sides of the drum roll (2), and left and right inner curved walls (11, 12) that are arranged spaced apart from the lower part of the outer surface of the drum roll (2).

[0007] And the above pair of anode bases (18, 19) are formed to be curved so as to be spaced apart from the lower outer surface of the drum roll (2), and are divided into a left anode base (18) that is relatively closer to the left wall (7), and a right anode base (19) that is relatively closer to the right wall (8).

[0008] Meanwhile, a plurality of thin electrode plates (not shown) are attached to the inner surface of a pair of anode bases (18, 19) facing the outer surface of the drum roll (2).

[0009] Additionally, a gap (20) is formed between the plurality of electrode plates and the outer surface of the drum roll (2).

[0010] And the plurality of support beams (15) are members that support a pair of anode bases (18, 19) spaced apart from the right and left inner curved walls (11, 12), and have a cross-section that is generally shaped like the letter I and extends parallel to the Y-axis.

[0011] In addition, the plurality of support beams (15) are arranged at equal angular intervals with respect to the center of rotation of the drum roll (2).

[0012] And a pair of current buses (21, 22) are for supplying current to a pair of anode bases (18) and a plurality of electrode plates attached thereto, and one (21) of the pair of current buses (21, 22) is electrically connected to the left end of the left anode base (18) and the other (22) is electrically connected to the right end of the right anode base (19).

[0013] In addition, the electrolyte supply nozzle (25) supplies the electrolyte to the gap (20), is arranged between the left and right anode bases (18, 19), and extends parallel to the Y-axis.

[0014] And, to prevent the frame (6) from being exposed to the electrolyte and corroded, the inner surfaces of the front and rear walls (not shown) of the frame (6) and the upper surfaces of the left and right inner curved walls (11, 12) are coated with rubber.

[0015] Additionally, the electrolytic cell (5) is supported by a pair of anode bases (18, 19) by a plurality of spaced support beams (15).

[0016] Meanwhile, the above electrolytic copper foil formation process is a process of redox reaction, in which a certain proportion of copper sulfate is transported to the anode through a pipe, and copper foil is formed on the cathode through the kinetic characteristics of the anode and cathode charges.

[0017] In particular, it is particularly important to ensure that the electrolyte (a certain proportion of copper sulfate liquid) is uniformly and continuously transported and supplied from the bottom to the anode tank in a wide direction of the metal foil forming device.

[0018] And previously, a bubble defoaming tube was installed in the electrolyte transport pipe, a diaphragm control valve that independently controls the flow rate was installed at the bottom of the bubble defoaming tube, and a duck bill tube or mixing cartridge was installed at the inlet.

[0019] In addition, the operation of the above-mentioned duckbill pipe for a long time required frequent replacement due to changes in shape.

[0020] In addition, the diaphragm control valve that independently controls the flow rate requires a high level of skill from the operator (controlling the valve opening and closing amount according to experience and sense), and the structure of the duckbill tube increases the flow rate of the electrolyte, which gives a large impact to the drum roll (2) of the cathode, and accordingly, vortices (or eddies) and bubbles are formed at the inlet, affecting the uniformity of the discharged electrolyte.

[0021] The present invention was created to solve the above problems, and its purpose is to provide an electrolyte supply nozzle device for a metal foil forming device that allows the electrolyte to be discharged uniformly without forming vortices or bubbles.

[0022] As a technical solution for achieving the above purpose, the electrolyte supply nozzle device for a metal foil forming device of the present invention is:

[0023] In an electrolyte supply nozzle device for a metal foil forming device,

[0024] At least one electrolyte supply pipe installed toward the drum roll of the electrolyte supply nozzle device, through which electrolyte is supplied;

[0025] An electrolyte chamber installed at the upper end of the electrolyte supply pipe so that the introduced electrolyte is collected and mixed to form a mixture;

[0026] It is characterized in that a plurality of electrolyte discharge holes inclined at a predetermined angle are formed on the upper part of the electrolyte chamber.

[0027] In the present invention, the electrolyte supply pipe is formed in the shape of a pipe, and the electrolyte chamber is installed perpendicular to the electrolyte supply pipe.

[0028] In the present invention, the electrolyte chamber is formed to have a diameter larger than that of the electrolyte supply pipe.

[0029] In the present invention, a perforated plate is further provided with a plurality of orifices formed at regular intervals so that the electrolyte introduced into the electrolyte chamber is discharged upward at a high pressure, and a plurality of partition walls are provided at the lower portion of the perforated plate so that the lower space of the electrolyte chamber is divided into spaces at regular intervals.

[0030] In the present invention, a flow member is provided at the upper part of the electrolyte chamber to form a flow path for the electrolyte so that the electrolyte discharged from the electrolyte discharge hole is discharged into the anode tank.

[0031] In the present invention, the flow member includes a flow plate installed in the center of the outside of the electrolyte chamber; and a guide plate installed opposite each other on the left and right sides of the outside of the electrolyte chamber, but installed at an angle toward the outside of the electrolyte chamber, thereby forming the flow path together with the flow plate.

[0032] In the present invention, the lower part of the guide plate is formed in a round shape like the anode tank, the lower part of the guide plate is fixed to the electrolyte chamber, and the upper part of the guide plate is fixed to the anode tank of the metal foil forming device.

[0033] In the present invention, a control valve for controlling the supply of electrolyte is installed at the lower part of each of the electrolyte supply pipes.

[0034] According to an embodiment of the present invention, the electrolyte can be uniformly discharged into the anode tank under the drum roll, so that the electrolyte can effectively avoid the influence of vortex (or eddy current) and bubble phenomenon as in the prior art.

[0035] In addition, the load of the electrolyte supply pump can be reduced, and low-flow and high-speed electrolysis (or electrolysis) can be implemented.

[0042] Figure 2 shows a schematic diagram of a metal foil forming device to which an electrolyte supply nozzle device according to the present invention is applied.

[0043] And FIG. 3 shows a detailed configuration diagram of an electrolyte supply nozzle device for a metal foil forming device according to the present invention of FIG. 2.

[0044] Additionally, FIG. 4 shows a side cross-sectional view of the electrolyte supply nozzle device of FIG. 3.

[0045] And, in Fig. 5 (a) to (c), detailed plan views, front views, and side views of the perforated plate of Fig. 4 are shown, respectively.

[0046] Referring to FIGS. 2 to 5, the electrolyte supply nozzle device for a metal foil forming device according to the present invention is configured to include at least one electrolyte supply pipe (110) installed toward a drum roll (2) of the electrolyte supply nozzle device and through which an electrolyte is supplied, and an electrolyte chamber (120) installed at the upper end of the electrolyte supply pipe (110) so that the introduced electrolyte is collected and mixed to form a mixed flow.

[0047] Additionally, a plurality of electrolyte discharge holes (121, 122) inclined at a predetermined angle (e.g., 15 to 45 degrees) are formed on the upper portion of the electrolyte chamber (120).

[0048] In particular, the electrolyte discharge holes (121, 122) are formed on the left and right sides of the electrolyte chamber (120), respectively, and are formed to be inclined in opposite directions.

[0049] And the electrolyte supply pipe (110) is formed in a pipe shape, and the electrolyte chamber (120) is installed perpendicular to the electrolyte supply pipe (110).

[0050] That is, the electrolyte supply pipe (110) is installed vertically toward the drum roll (2), and the electrolyte chamber (120) is installed and supported across the upper portion of the electrolyte chamber (120).

[0051] At this time, it is preferable that the electrolyte chamber (120) be formed with a diameter larger than that of the electrolyte supply pipe (110) for smooth flow and discharge.

[0052] In addition, the electrolyte supply nozzle device for the metal foil forming device according to the present invention is provided with a perforated plate (130) having a plurality of orifices (131) formed at regular intervals so that the electrolyte introduced into the electrolyte chamber (120) is discharged upward at a high pressure.

[0053] At the lower part of this perforated plate (130), as shown in Fig. 5, a number of partition walls (133) are provided to divide the lower space of the electrolyte chamber (120) into certain intervals and spaces.

[0054] At this time, the partition wall (133) is formed in a semicircular shape to fill the lower shape inside the electrolyte chamber (120), as shown in (c) of FIG. 5.

[0055] And, at the upper part of the electrolyte chamber (120), a flow member (161, 162, 170) is provided to form a flow path for the electrolyte so that the electrolyte discharged from the electrolyte discharge hole (121, 122) is discharged into the anode tank (181, 182) under the drum roll (2).

[0056] These flow-guide members (161, 162, 170) are configured to include a flow-guide plate (170) installed in the center of the outside of the electrolyte chamber (120), and a guide plate (161, 162) installed opposite each other on the left and right sides of the outside of the electrolyte chamber (120) but installed at an angle toward the outside of the electrolyte chamber (120) to form the flow path together with the flow-guide plate (170).

[0057] In addition, the lower part of the guide plate (170) is formed in a round shape such as an anode tank (181, 182) or a drum roll (2), and the lower part of the guide plate (161, 162) is fixed to the electrolyte chamber (120) and the upper part of the guide plate (161, 162) is welded and fixed to the anode tank (181, 182) of the metal foil forming device.

[0058] And, a control valve (111) is installed at the bottom of each of the electrolyte supply pipes (110) so that the supply of electrolyte can be individually controlled or controlled (e.g., flow rate, etc.) for each electrolyte supply pipe (110).

[0059] That is, since a control valve (111) is installed in each of the electrolyte supply pipes (110), the control valves (111) can be individually controlled, and thus the electrolyte can be effectively discharged according to the situation at each location.

[0060] The operation of the electrolyte supply nozzle device for a metal foil forming device according to the present invention having the configuration described above is described as follows.

[0061] Referring again to FIGS. 2 to 5, the electrolyte supply nozzle device for a metal foil forming device according to the present invention is provided with a perforated plate (130) having a plurality of orifices (131) formed inside the electrolyte chamber (120), so that the electrolyte can accelerate and implement stable flow characteristics in the electrolyte chamber (120) space above the perforated plate (130).

[0062] In addition, a plurality of electrolyte discharge holes (121, 122) are formed in two rows at the top of the electrolyte chamber (120) and are formed at a predetermined angle, so that the electrolyte can achieve secondary acceleration and stable flow in the electrolyte discharge holes (121, 122).

[0063] And, just before the electrolyte is discharged from the electrolyte discharge hole (121, 122) and flows into the anode tank (181, 182), a guide plate (161, 162) and a flow guide plate (170), which are flow guide members (161, 162, 170), are installed so that the electrolyte can naturally flow into the anode tank (181, 182) along the direction in which the drum roll (2) of the cathode is tangential.

[0064] Therefore, the electrolyte can effectively avoid the effects of conventional vortex (or eddy) and bubble phenomena.

[0065] In addition, the load of the electrolyte supply pump (not shown) can be reduced, and low-flow and high-speed electrolysis (or electrolysis) can be implemented.

[0066] As described above, the present invention has been described with reference to one embodiment shown in the drawings, but this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom.

[0067] Therefore, the true scope of protection of the present invention should be determined solely by the appended claims.

[0068] It is industrially applicable because it allows the electrolyte to be uniformly discharged into the anode tank at the bottom of the drum roll.
