The present invention relates to a processing method for carbon nanotubes and a processing device for the carbon nanotubes. More specifically, a processing method for carbon nanotubes to remove metal foreign substances generated during the carbon nanotube synthesis process and a processing device for the carbon nanotubes. It is about processing equipment.

Carbon nanotubes have a variety of applications, including aerospace, biotechnology, environmental energy, medicine, medical care, electronics, and computers.

In particular, recently, with the growth of the IT industry and the global electric vehicle market, carbon nanotubes have been used as a conductive material, which can be said to be a core material for lithium-ion batteries.

Republic of Korea Patent Publication No. 10-2018-0090462 discloses a conventional method for producing carbon nanotube fibers and carbon nanotube fibers produced thereby.

In the conventional carbon nanotube process or processing process, metal foreign substances generated within the raw material and during the process were removed using a permanent magnet, but this method had the problem of requiring regular cleaning and having to stop the process.

In addition, permanent magnets had a problem in that carbon nanotubes were increasingly attached to the surface of the magnet, resulting in reduced iron removal efficiency.

In addition, there was a problem in that the strength of the magnetic field lines could not be adjusted, so it was not possible to respond separately to each grade of product.

Therefore, the present invention was created to solve the above problems, and the object of the present invention is to provide a processing method for carbon nanotubes that does not require regular cleaning and maintenance and can maintain a constant iron removal efficiency, and processing of the carbon nanotubes.

In the foreign matter removal step, when the magnetic field lines are turned on in the electromagnetic remover, magnetic force is generated in the electromagnet, causing metal foreign substances in the carbon nanotube to stick to the inside of the electromagnetic remover.

When the electromagnet remover is turned off in the foreign matter removal step, the magnetic force of the electromagnet is removed, causing metal foreign substances stuck inside the electromagnet remover to fall off and be transferred to a separate return line.

In the foreign matter removal step, the electromagnetic stripper can adjust the strength of the magnetic force, and the magnetic force strength of the electromagnetic stripper can be strengthened to cause metal foreign substances to stick to the inside of the electromagnetic stripper.

If the magnetic force of the electromagnetic stripper is weakened in the foreign matter removal step, metal foreign substances stuck inside the electromagnetic stripper can be caused to fall and be transferred to a separate return line.

In the foreign matter removal step, the interior of the electromagnetic iron remover may be vibrated to induce the carbon nanotubes to fall from the interior of the electromagnetic iron remover.

In the foreign matter removal step, the electromagnet remover can adjust the vibration intensity of the electromagnet.

It may include a pelletizer formed at the lower part of the iron removal unit to feed the carbon nanotubes that have passed through the iron removal unit into the dryer.

The filter unit may be made of a filter consisting of a plurality of grids.

The filter unit may be vibrated so that the intensity of vibration can be adjusted.

It may include a vibration motor that provides power to vibrate the filter unit.

The pelletizer is formed to connect the iron removal unit and the pelletizer, and is connected to the main line and a main line that guides the movement of the carbon nanotubes from which metal foreign substances are separated from the iron removal unit to the pelletizer. A separate return line that leads to the recovery of metal contaminants separated from the carbon nanotubes, and a two-way valve installed between the main line and the return line to selectively open either the main line or the return line. It can be included.

The electromagnet part can adjust the magnetic force from 0 to 12000G.

The electromagnet unit may be turned on/off by manipulating the power source.

The main reactor can produce the carbon nanotubes in powder form.

According to the present invention, since metal foreign substances in carbon nanotubes are removed with an electromagnetic iron remover, the strength of the magnetic force can be adjusted, which has the effect of adjusting the strength of the magnetic force differently depending on the grade and characteristics of the product.

In addition, as the electromagnetic iron remover is turned on/off, the metal foreign matter stuck to the electromagnetic iron remover can be removed so that the thickness does not become too thick, which has the effect of maintaining the iron removal efficiency of the electromagnetic iron remover.

It must be interpreted with meaning and concept consistent with the technical idea of the present invention based on the principle that it is. Therefore, the embodiments described in this specification and the configurations shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent the entire technical idea of the present invention, so at the time of filing the present application, various alternatives may be used to replace them. It should be understood that there may be equivalents.

In the drawings, the size of each component or specific part constituting the component is exaggerated, omitted, or schematically shown for convenience and clarity of explanation. Therefore, the size of each component does not completely reflect the actual size. If it is determined that specific descriptions of related known functions or configurations may unnecessarily obscure the gist of the present invention, such descriptions will be omitted.

FIG. 1 is a flowchart showing a carbon nanotube processing method according to the first embodiment of the present invention, and FIG. 2 is a process diagram schematically showing a process according to the carbon nanotube processing method of FIG. 1.

As shown in Figures 1 and 2, the carbon nanotube processing method according to the first embodiment of the present invention includes a synthesis step (S1), a transfer step (S2), a foreign matter removal step (S3), and a drying step (S4). ) and packaging step (S5).

The synthesis step (S1) may be a step of synthesizing carbon nanotubes in the main reactor 100.

Carbon nanotubes (CNTs) may be an allotrope of carbon with a cylindrical nanostructure.

Nanotubes have a cylindrical fullerene-based structure, and are called carbon nanotubes because they are made in the shape of a long, hollow tube with a membrane made of a layer of carbon atoms called graphene as the wall.

Carbon nanotubes have excellent mechanical, electrical, and thermal properties, which can replace existing additives in the field of nanocomposite manufacturing.

In particular, the field of replacing carbon black, which is used as a conductive filler in the positive electrode of lithium-ion batteries, may be the most promising field.

Currently, major battery companies have developed lithium secondary batteries with improved characteristics by using carbon nanotubes as anode additives, and they can be used in mobile devices and electric vehicles, which are expected to rapidly expand the market in the future.

Carbon nanotubes synthesized in the main reactor 100 may be produced in powder form.

The transfer step (S2) may be a step of transferring the carbon nanotubes whose synthesis has been completed in the synthesis step (S1).

In the transfer step (S2), carbon nanotubes in powder form can be transferred using a transfer device such as a transfer belt or conveyor belt.

The carbon nanotubes transferred in the transfer step (S2) may be supplied to the storage unit 300 and stored.

And the storage unit 300 can input the stored carbon nanotubes into the electromagnetic iron remover 400.

The foreign matter removal step (S3) may be a step of removing metal foreign substances from the carbon nanotubes introduced from the storage unit 300 where the carbon nanotubes transferred in the transfer step (S2) are stored. Specifically, this may be a step of removing metal foreign substances mixed in carbon nanotubes through an electromagnetic iron stripper 400 using an electromagnet.

Metal foreign matter in carbon nanotubes is a fine metal foreign matter generated during the process of synthesizing carbon nanotubes and may be formed of iron (Fe), chromium (Cr), nickel (Ni), etc. If these metal foreign substances are mixed into carbon nanotube applied products, they may cause defects.

In the foreign matter removal step (S3), when the electromagnetic force line is turned on, the electromagnetic iron stripper 400 generates magnetic force in the electromagnet and can magnetically attract metal foreign substances mixed in the carbon nanotubes. In this way, metal foreign substances can be removed from the carbon nanotube by magnetically attracting them and causing them to stick to the inside of the electromagnetic stripper 400.

On the other hand, when the magnetic field lines of the electromagnetic stripper 400 are turned off, the magnetic force of the electromagnet is removed, allowing metal foreign substances stuck inside the electromagnetic stripper 400 to fall off. In this way, metal foreign substances that have fallen off from the inside of the electromagnetic iron remover 400 can be induced to be transferred to the metal foreign matter storage unit (not shown) through a return line 410b provided separately at the lower part of the electromagnetic iron remover 400.

Meanwhile, in the foreign matter removal step (S3), the electromagnetic iron stripper 400 can adjust the strength of the magnetic force. If the magnetic force of the electromagnetic iron remover 400 is strengthened, metal foreign substances, including metal foreign substances of relatively heavy weight, can be adhered to the inside of the electromagnetic iron remover 400.

In addition, if the magnetic force strength of the electromagnetic iron remover 400 is weakened in the foreign matter removal step (S3), metal foreign substances stuck to the inside of the electromagnetic iron remover 400 can be separated from the inside of the electromagnetic iron remover 400. It is possible to induce the transfer of metal foreign substances to the return line 410b. Here, the strength of the magnetic force can be adjusted to induce the removal of relatively light metal foreign substances.

The foreign matter removal step (S3) according to the second embodiment of the present invention may vibrate the interior of the electromagnetic demolder 400 to induce the carbon nanotubes to fall from the interior of the electromagnetic demolder 400. At this time. By adjusting the intensity of the vibration that vibrates the inside of the electromagnetic iron stripper 400, if there is a lot of metal foreign matter inside the electromagnetic iron remover 400, the vibration becomes stronger, and if there is a small amount of metal foreign material inside the electromagnetic iron remover 400, the vibration intensity is made weaker. can do. By removing the metal foreign matter stuck to the inside of the electromagnetic remover 400 in this way, it is possible to prevent the metal foreign matter from sticking thickly to the inside of the electromagnetic remover 400 and weakening the strength of the magnetic force, thereby reducing efficiency.

The drying step (S4) may be a step of drying the carbon nanotubes from which metal foreign substances have been removed in the foreign matter removal step (S3) by putting them into the dryer 500.

The packaging step (S5) may be a step of packaging the carbon nanotubes dried in the drying step (S4) by putting them into the packaging machine 600.

The main reactor 100 can synthesize carbon nanotubes to produce them in powder form.

Carbon nanotubes synthesized in the main reactor 100 may be transported by a transfer unit 200 formed of a transfer belt, conveyor belt, etc.

Carbon nanotubes transferred by the transfer unit 200 may be stored in the storage unit 300. The storage unit 300 can store carbon nanotubes and supply them to the electromagnetic iron remover 400 in a certain amount for a certain period of time.

It is a perspective view showing only the filter unit, and Figure 6 is a perspective view showing only the filter unit according to an embodiment of the present invention.

As shown in Figures 4 to 6, the iron removal part 410 according to an embodiment of the present invention is formed around the filter part 411 and the filter part 411 installed at the center, so that the filter part 411 It may include an electromagnet unit 419 that magnetizes.

Referring to FIG. 5 , the filter unit 411 may be assembled by stacking a plurality of filters 411a made of a plurality of metal grids as shown in FIG. 6 .

The pelletizer 410 has a main line 410a for moving carbon nanotubes, a return line 410b for discharging metal foreign substances separated from the carbon nanotubes, and between the main line 410a and the return line 410b. It may include a 2-way valve 410c that is installed and selectively opens either one of the two.

The main line 410a is formed to connect the iron removal unit 410 and the pelletizer 420, and guides the movement of the carbon nanotubes from which the metal foreign substances are separated from the iron removal unit 410 to the pelletizer 420. can do.

The return line 410b may be connected to the lower part of the main line 410a to be connected to the iron removal unit 410, and a 2-way valve 410c may be installed between the return line 410b and the main line 410a. You can. The two-way valve 410c opens either the main line 410a or the return line 410b to allow carbon nanotubes to move through the main line 410a or to discharge metal foreign substances through the return line 410b. It can be done.

That is, when the electromagnet unit 419 is on, the main line 410a is opened to allow the carbon nanotubes from which metal impurities have been removed to move through the main line 410a, and when the electromagnet unit 419 is off, it is returned. By opening the line 410b, metal foreign substances falling from the filter unit 411 from which the magnetic force has been removed can be discharged through the return line 410b.

Figure 7 is a cross-sectional view schematically showing the internal main part of the electromagnetic iron stripper according to the second embodiment of the present invention from the side.

As shown in FIG. 7, according to the second embodiment of the present invention, the electromagnetic iron stripper 400 accommodates cooling water inside the iron stripping unit 410 and maintains the temperature of the cooling water on one side of the iron stripping unit 410. By installing a cooler 412 capable of preventing an increase in temperature inside the iron removal unit 410, it can be stabilized.

Additionally, a vibration motor 430 may be installed between the iron removal unit 410 and the pelletizer 420 to vibrate the filter unit 411 (see FIG. 6).

As the filter unit 411 is vibrated to prevent metal foreign substances and carbon nanotubes from sticking to the filter unit 411, the magnetic force of the magnetized filter unit 411 is weakened, causing metal foreign substances to stick to the filter unit 411. This can prevent the efficiency from decreasing.

The vibration motor 430 can adjust the vibration intensity of the filter unit 411 to vary the vibration intensity of the filter unit 411 depending on the amount of metal foreign substances and carbon nanotubes adhering to the filter unit 411.

The conventional method had a problem in that it was difficult to apply to the process because the only way to clean contaminants attached to the surface was by a person.

In addition, because the magnetic force lines were fixed, there was a problem that different magnetic force lines could not be applied depending on the product grade.
