Description

Copper foil material manufacturing equipment for cathode materials {MATERIALS MANUFACTURING APPARATUS OF COPPER FOIL for ANODE MATERIALS}

The present invention relates to an apparatus for manufacturing copper foil material for anode materials, and specifically, to replace high-purity wheat berry used in manufacturing copper foil for anode materials of secondary batteries, low-purity general copper is used to produce granule-shaped anodes. By manufacturing copper foil material, price competitiveness is improved and copper foil material that can reduce costs can be provided. By manufacturing the copper foil material for anode material in the form of granules, the dissolution rate increases when dissolved in an electrolyte solution, making it possible to provide a copper foil material that can reduce costs. This relates to a device for manufacturing copper foil material for anode materials that can increase production efficiency when manufacturing copper foil.

As environmental regulations have recently been strengthened and demand for electric vehicles has increased, the rapidly growing electric vehicle market has emerged as a future business, and the importance of copper foil is increasing.

Copper foil, also called battery foil, is considered a key material for secondary batteries used in electric vehicles. Copper foil for secondary batteries is considered a key component of electric vehicle batteries (secondary batteries) because it dissipates heat generated from the battery to the outside and serves as a support to maintain the shape of the electrode. In particular, copper foil is used as a thin film for the cathode material, which is the four core materials of electric vehicle batteries (anode material, cathode material, separator, and electrolyte).

In particular, in order to increase the capacity of secondary batteries, the energy density per unit area must be increased, and to this end, the thickness of the copper foil must be made thinner to make the area per unit volume larger and the weight less.

This copper foil is largely manufactured using the roll rolling method and the electrolytic method. The roll rolling method has the disadvantage that production costs increase as the thickness becomes thinner, so the electrolytic method, which is a method of plating copper through electrolysis, is mainly used. We are manufacturing copper foil for secondary batteries.

At this time, copper foil for secondary batteries using the electrolytic method is generally supplied from electrolytic copper or Millbury-grade high-quality copper scrap, manufactured into wire rod through casting, casting + rolling, or casting + rolling + drawing, and the manufactured wire rod is washed. And after cutting, it can be prepared by dissolving it in sulfuric acid solution, which is an electrolyte.

However, cut wire rods are manufactured through rolling, drawing, and cutting processes. During rolling and drawing, they are exposed to oil components such as rolling oil and drawing oil, so a cleaning process for degreasing is essential. The process is complicated, so the cost of copper foil is high. As the supply increases, there is a problem with the smooth supply of raw materials such as electrolytic copper or wheatberry-grade high-quality copper scrap.

Accordingly, in an effort to solve the above problems, Korean Patent Publication No. 10-2023-0034813 discloses a technology related to an irregular copper material with excellent dissolution performance when dissolved in an electrolyte for manufacturing electrolytic copper foil and a method of manufacturing the same.

However, in the case of the above-described prior art, raw materials such as electrolytic copper or copper scrap, which are not readily available, are supplied and melted to manufacture irregular copper materials, which reduces price competitiveness and makes it impossible to reduce costs.

The present invention was created to solve the above problems. In order to replace high-purity wheat berry, a granular copper foil material is manufactured using low-purity general copper, thereby improving price competitiveness and reducing costs. The purpose is to provide a copper foil material manufacturing apparatus for an anode material that provides a copper foil material capable of this.

Meanwhile, the first heating device 12 may be configured as an induction coil heater or a high-temperature heating element, and any device can be changed for the purpose of maintaining the high temperature state of the melt 1 during the discharge process of the melt 1. It can be applied in any way, and it may also be possible to install it in an area at the top or bottom of the melting furnace 10, but the present invention is not limited thereto.

Next, as shown in FIGS. 1 and 2, the tundish 20 is located at the bottom of the melting furnace 10 and collects the melt 1 discharged from the outlet 11 of the melting furnace 10. It has an internal cavity 21 to accommodate, and a plurality of discharge holes 22 are formed at preset intervals in one area of the side along the circumferential direction of the side, and a plurality of discharge holes 22 are formed in one area to prevent cooling of the molten body 1. A second heating device 24 is disposed, and as the tundish 20 rotates, an inertial force is generated on the melt 1 accommodated in the internal cavity 21, thereby causing the melt 1 to flow through the discharge port 22. It is to be discharged.

In addition, a refractory material 25 is installed on the inner wall of the tundish 20, and the heat generated from the molten body 1 accommodated in the internal cavity 21 of the tundish 20 is transferred to the tundish (20). 20) can be blocked from being transmitted directly to .

At this time, it is preferable that the refractory material 25 axial to the inner wall of the tundish 20 be made of a material such as magnesium or alumina, which has a strength higher than that of iron and stainless steel.

Meanwhile, the discharge port 22 is a configuration for discharging the molten body 1 accommodated in the internal cavity 21 of the tundish 20 from the inside of the tundish 20 to the outside, and the turn A plurality of discharge holes 22 may be formed at predetermined intervals along the circumferential direction of the side of the dish 20 .

For example, as shown in FIG. 2, if the preset interval is 120 degrees, three discharge holes 22 may be formed at intervals of 120 degrees along the circumferential direction of the side of the tundish 20. .

At this time, the interval at which the discharge port 22 is formed may be changed, and the present invention is not limited thereto.

On the other hand, referring to FIG. 3, the tundish 22 is rotated due to the melt 1 discharged through the tundish 20 as the tundish 20 rotates. In order to prevent deformation and damage, it will have a length corresponding to the thickness of the refractory material 25 axially routed on the inner wall of the tundish 20 and include a hollow spout 23 whose inner peripheral surface is made of a refractory material. You can.

For example, the melt 2 discharged through the spout 23 is solidified within the spout 23, making it difficult to discharge the melt 1, or the refractory material in the spout 23 cracks and the refractory material It will be possible to replace it when its useful life expires, and in addition, it can be replaced at any time for the purpose of maintaining smooth discharge of the melt 1, and the present invention is not limited thereto.

Meanwhile, the second heating device 24 is configured to prevent the molten body 1 accommodated in the internal cavity 21 of the tundish 20 from cooling and solidifying, and the tundish 20 ) It can be understood as a configuration that is disposed in one area of the tundish 20 to generate heat so that the molten body 1 can maintain its liquid form without solidifying.

As an embodiment of the present invention, referring to FIGS. 1 and 2, the second heating device 24 may be provided at the bottom of the tundish 20, and heat is generated from the bottom of the tundish 20. At least one heating device among a gas torch, an induction coil heater, and a high-temperature heating element may be used to generate heat and transfer it to the molten body 1 within the tundish 20. In addition, the tundish 20 Any heating device may be modified and applied for the purpose of maintaining the liquid state of the molten body 1 contained therein, and the present invention is not limited thereto.

In addition, as another embodiment of the present invention, one or more second heating devices 24 may be provided in an upper area along the circumferential direction of the tundish 20, At least one of a gas torch, an induction coil heater, and a high-temperature heating element can be used to generate heat on the side of the tundish 20 and transfer the heat to the molten body 1 within the tundish 20. In addition, any heating device may be modified and applied for the purpose of maintaining the liquid state of the molten body 1 contained in the tundish 20, and the present invention is not limited thereto.

Continuing the explanation by going back to FIG. 1, the first water tank 30 may be located at the bottom of the tundish 20.

The first water tank 30 has a plurality of coolant spray nozzles 33 formed in a lower area, so that high-pressure coolant is sprayed from the bottom to the top in a cyclonic manner. The water sprayed from the coolant spray nozzles 33 is It is preferable to understand that the granular copper foil material 100 for an anode material is formed and collected when high-pressure coolant comes into contact with the molten body 1 discharged from the tundish 20.

At this time, the first water tank 30 may be provided with a cylindrical part 31 having a vertical surface and a conical part 32 having an inclined surface so that the internal cross-sectional area becomes narrower toward the lower end.

Meanwhile, as shown in (a) of FIG. 4, the coolant spray nozzles 33 are spaced at regular intervals along the circumferential direction from one area of the inner surface of the inclined surface of the cone-shaped portion 32 of the first water tank 30. Multiple numbers may be formed.

Also, referring to (b) of FIG. 4, according to an embodiment of the present invention, the coolant spray nozzle 33 is configured to spray high-pressure coolant from the bottom to the top in a cyclonic manner. By being formed in a shape inclined at a preset angle from the inclined surface of the conical portion 32 of 30), it is preferable to understand that high-pressure coolant is discharged while rotating from the lower part of the first water tank 30 to the upper direction. will be.

Meanwhile, according to one embodiment of the present invention, high-pressure coolant is sprayed from the coolant spray nozzle 33. At this time, the pressure for spraying the coolant is determined by the coolant sprayed from the coolant spray nozzle 33 and the tundish 20. ) It would be preferable to spray the coolant by applying a pressure that prevents the melt 1 from going over the outside of the first water tank 30 when it comes into contact with the molten body 1 discharged from ).

In addition, according to an embodiment of the present invention, the number of coolant spray nozzles 33 and the angle at which the coolant spray nozzles 33 are inclined from the inclined surface of the cone-shaped portion 32 are determined by the number of coolant spray nozzles 33 that must be reached by spraying the coolant. It may vary depending on the location or the size of the first water tank 30, but the present invention is not limited thereto.

On the other hand, the granular copper foil material 100 for an anode material, which is formed by contacting the coolant sprayed from the coolant spray nozzle 33 with the molten body 1 discharged from the tundish 20, is melted at a high temperature. In the heat transfer process when metal and coolant come into contact, the principle of steam explosion can be used, in which the coolant explosively generates high-pressure steam and transmits shock waves to the surroundings.

That is, the granular copper foil material 100 for an anode material is discharged from the coolant sprayed from the coolant spray nozzle 33 formed in the first water tank 30 and the discharge port 22 of the tundish 20. It is preferable to understand that it is formed by contact with the high temperature molten body (1) and a steam explosion.

Specifically, the molten body 1 is granulated through a steam explosion occurring when the coolant sprayed from the coolant spray nozzle 33 comes into contact with the molten body 1 discharged from the discharge port 22 of the tundish 20. At the same time as being dispersed in the form, the melt 1 dispersed in the form of granules is first cooled by the coolant sprayed from the coolant spray nozzle 33 and precipitates into the coolant stored in the first water tank 30. By secondary cooling, the granular copper foil material 100 for an anode material is manufactured.

Meanwhile, a steam explosion occurring when the melt 1 discharged from the tundish 20 comes into contact with the high-pressure coolant sprayed from the coolant spray nozzle 33 of the first water tank 30 is caused by the melt 1 ) It can be understood that the intensity of the explosion varies depending on the temperature difference between the temperature of the coolant and the coolant sprayed from the coolant spray nozzle 33.

Therefore, by precisely controlling the temperature of the coolant stored in the first water tank 30 and the coolant sprayed from the coolant spray nozzle 33 to control the intensity of the steam explosion, the melt 1 is dispersed in the form of granules. It would be desirable to manufacture the copper foil material 100 for an anode material in the form of a granule that does not stick or combine with each other and has a large surface area.

In addition, the melt 1 dispersed in the form of granules, which is primarily cooled by the coolant sprayed from the coolant spray nozzle 33, precipitates into the coolant stored in the first water tank 30, causing secondary coolant due to the temperature difference. Since water vapor explosion may occur, it would be desirable to precisely control the temperature of the coolant sprayed from the coolant spray nozzle 33 and the coolant stored in the first water tank 30.

That is, according to an embodiment of the present invention, the melt 1 is dispersed in the form of granules so that they do not stick or combine with each other and are manufactured into the copper foil material 100 for an anode material in the form of a granule with a large surface area, and the coolant is sprayed. The melt 1 dispersed in the form of granules that is primarily cooled by the coolant sprayed from the nozzle 33 precipitates into the coolant stored in the first water tank 30, causing a secondary steam explosion due to the temperature difference. In order to prevent this, the preferred temperature of the coolant stored in the first water tank 30 and the coolant sprayed from the coolant spray nozzle 33 is preferably about 30 degrees, and the temperature of the coolant is as necessary. It can be adjusted accordingly, and the present invention is not limited thereto.

In addition, the coolant is stored in the first water tank 30 through primary cooling due to the coolant sprayed from the coolant spray nozzle 33 and secondary cooling due to precipitation in the coolant stored in the first water tank 30. It will be possible for the temperature of the coolant to remain constant.

Meanwhile, the first water tank 30 can store cooling water up to a preset water level inside, and as the copper foil material 100 for an anode material in the form of granules is deposited and collected in the lower part of the first water tank 30, When the level of the stored coolant exceeds the preset level, the coolant in the first water tank 30 is discharged through a coolant outlet (not shown) formed in one area of the first water tank 30 to level the water level. can be adjusted.

At this time, the preset water level of the first water tank 30 is the melt 1 discharged from the tundish 20 and the high-pressure coolant sprayed from the coolant spray nozzle 33 of the first water tank 30. It would be desirable to set it lower than the position where water vapor explosion occurs so that the coolant stored in the first water tank 30 other than the coolant sprayed from the coolant spray nozzle 33 does not contact the molten body 1. .

In addition, the cooling water outlet is formed in one area of the conical part 32 of the first water tank 30, or in one area of the side of the cylindrical part 31 of the first water tank 30, that is, at a preset water level. It may be formed in the corresponding area, and the present invention is not limited thereto.

Meanwhile, as an embodiment of the present invention, when the cooling water outlet is formed in one area of the conical portion 32 of the first water tank 30, the cooling water stored in the first water tank 30 is at a preset level. If it exceeds , the water level may be adjusted by opening the cooling water outlet formed in one area of the conical portion 32 of the first water tank 30.

In addition, as another embodiment of the present invention, when the cooling water outlet is formed in an area of the side of the cylindrical part 31 of the first water tank 30, that is, an area corresponding to a preset water level, the cooling water outlet continues to be opened. By opening the coolant stored in the first water tank 30, if the coolant stored in the first water tank 30 exceeds a preset water level, the coolant is automatically discharged through the open coolant outlet to adjust the water level.

Continuing the explanation by going back to FIG. 1, the second water tank 40 may be located at the bottom of the first water tank 30.

The second water tank 40 is the first water tank ( 30) It is desirable to understand the configuration in which the coolant discharged to the outside is collected.

At this time, the second water tank 40 is injected from the coolant spray nozzle 33 and the coolant discharged from the first water tank 30, comes into contact with the molten body 1, and is then discharged out of the first water tank 30. It is preferable that the first water tank 30 is formed in a cylindrical shape so that the cooling water can be collected, but it can be changed to any shape as long as it is large enough to accommodate the first water tank 30. It is possible, and the present invention is not limited thereto.

In addition, the coolant collected in the second water tank 40 is collected through a process of discharging the coolant through the coolant outlet of the first water tank 30 and a steam explosion process, thereby increasing or decreasing the temperature of the coolant. It may be understood that the coolant has a different temperature from the coolant used in the first water tank 30.

Meanwhile, referring to FIG. 1, the second water tank 40 may be connected to the third water tank 50.

The third water tank 50, when the water level of the second water tank 40 exceeds a preset water level (for example, 2/3 of the height of the second water tank 40), the second water tank ( It is preferable to understand that the configuration allows the coolant to be re-cooled by collecting the coolant in 40) and supplying it to the cooler 60.

At this time, the cooler 60 re-cools the coolant supplied from the third water tank 50 to the temperature of the coolant used in the first water tank 30 and cools the coolant spray nozzle 33 of the first water tank 30. ) can be provided.

That is, the apparatus 1000 for producing a copper foil material for an anode material of the present invention supplies the cooling water used in the process of manufacturing the copper foil material 100 for an anode material into the first water tank 30, the second water tank 40, and the first water tank 30. 3 As it is possible to circulate and reuse through the water tank 50 and the cooler 60, there is an effect of reducing operating costs and improving energy efficiency of the apparatus 1000 for manufacturing copper foil material for anode material.

Going back to FIG. 1 and continuing the description, the apparatus 1000 for manufacturing copper foil material for an anode material of the present invention may further include an extension rod 70, a rotation control unit 80, and a fixing bar 90.

The extension rod 70 is coupled to the lower end of the tundish 20 and is formed in a cylindrical shape with a preset length, and one end of the extension rod 70 is connected to the lower end of the tundish 20. can be combined with

Meanwhile, as an embodiment of the present invention, the extension rod 70 is not separated when the tundish 20 rotates, and has various shapes so that it can be separated after the rotation of the tundish 20 stops. It can be coupled to any coupling method as long as the extension rod 70 is not separated from the tundish 20 while the tundish 20 rotates, and the present invention relates to this. Not limited.

Next, the rotation control unit 80 is coupled to the other end of the extension rod 70, one end of which is coupled to the tundish 20, to control the rotation of the tundish 20, and uses a rotation motor (not shown). It can be composed of poems).

At this time, when the rotation control unit 80 receives external power and operates the rotation motor, the extension rod 70 connected to the rotation control unit 80 rotates, and the extension rod 70 rotates. The tundish 20 can be rotated by.

Meanwhile, the rotation speed of the rotation motor may be varied by the user depending on the amount of the melt 1 discharged from the tundish 20, but the present invention is not limited thereto.
