The present invention relates to a method of manufacturing an activated carbon filter and an activated carbon filter produced through the same.

With the advancement of the industry, the problem of environmental pollution has emerged, and water, which is the most important in human life, has become inevitable from pollution problems. In general, the water supply is supplied to the user in the form of tap water after being purified at the water supply facility before being supplied, but due to the aging of the water supply, there is a possibility that suspended solids from outside or rust or infectious bacteria released from the aging water supply may exist. It is difficult to eat immediately.

In addition, in suburbs where water supply facilities are difficult to enter, drinking water is obtained through groundwater, but it is difficult to secure safety due to contaminated water discharged from livestock farms.

In order to solve this problem, the purified water was pre-purified or used to provide a water purifier that is a device that can purify the raw water. Such a water purifier is provided with a filter that can filter out inorganic substances such as rust and organic matter such as bacteria that are dissolved in raw water, thereby removing contaminants in the raw water.

The activated carbon filter using activated carbon among these filters uses carbonaceous material made of coal such as coal or lignite, anthracite and bituminous coal as raw materials.

Referring to FIG. 1, in the method of manufacturing activated carbon filter 1 according to an embodiment of the present invention, an active part forming step of forming an active part 40 on an outer circumferential surface of the core 20 (S100), and an active part 40. Active part surface cleaning step (S200) to clean up the surface of the active part, active part drying step (S300) for drying the core 20, the active part 40 is formed, the active part 40 of the dried core 20 Melt layer forming step (S400) of forming a melt layer made of a plastic melt on the surface and may include a finishing step (S500) by mounting the cap cover 60 on both ends.

Here, in the method for manufacturing activated carbon filter 1 according to an embodiment of the present invention, a filtering net forming step (not shown) for forming a filtering net (not shown) in the core 20, and a filtering net drying step (not shown) form an active part. It may be a manufacturing method that is performed sequentially before step S100 begins. At this time, when the sieve forming step and the sieve drying step is added, the active portion 40 is formed on the outer surface of the sieve, and if the sieve forming step and the sieve drying step is not performed, the active portion 40 is formed on the outer peripheral surface of the core.

Hereinafter, a description will be given of the sieve forming step and the sieve drying step, the method for manufacturing the activated carbon filter 1 according to an embodiment of the present invention.

In the sieve forming step, after forming a sieve net having a molding die rotating while moving up and down, the core 20 made of a porous core or a melt brown core is mounted on the molding die.

And after supplying water to the sieve tank, and put the short fibers and pulp in the sieve tank and mixed with water to form the sieve moldings, the molding mold provided with the core 20 is moved to the lower position inside the sieve tank Be sure to For example, the pulp may be natural pulp.

Next, the sieve mesh is adsorbed while rotating the molding die provided with the core 20 to form a sieve (not shown) on the outer surface of the core 20.

In the sieve drying step, the core 20 in which the sieve (not shown) is formed is removed from the sieve tank, the core 20 is removed from the shaping mold of the sieve tank, and the core 20 is dried through a drying room or natural drying.

However, the sieve formed on the outer circumferential surface of the core 20 through the sieve forming step and the drying sieve drying step may block fine through holes formed on the outer circumferential surface of the core 20 to weaken the suction force by the negative pressure applied to the inside of the core 20. It is weak in durability and can be easily separated from the core 20. In addition, these strainers have several negative aspects, such as problems caused by the decay or oxidation of the pulp.

Therefore, the active part forming step (S100) may be performed for the first time without forming the strainer.

Hereinafter, the active part forming step (S100) will be described. The active part forming step (S100) is a step performed for the first time in the method for manufacturing activated carbon filter 1 according to an embodiment of the present invention.

In one embodiment of the present invention, the active part forming step S100 may include a pretreatment step S110 and an adsorption step S130.

In one embodiment of the present invention, the pretreatment step (S110) is such that activated carbon moldings are formed in the activated carbon raw material tank. Granular activated carbon having particle sizes of different sizes is classified according to particle size, and then a plurality of materials are mixed. For example, activated elastomeric moldings can be made by mixing granular activated carbon, acrylic short fibers, PP short fibers, pulp and water. At this time, the pulp may be natural pulp or artificial pulp. In addition, the acrylic short fibers and PP short fibers are preferably mixed with each other, but are not limited thereto. An active elastic molded article may be formed without the acrylic short fibers.

This pretreatment step (S110) is, for example, forming an activated carbon molding containing granular activated carbon having a particle size of 200 mesh or more and less than 130 mesh, and forming an activated carbon molding including granular activated carbon having a particle size of 130 mesh or more and less than 60 mesh. And forming an activated elastic molding comprising granular activated carbon having a particle size of 60 mesh or more and less than 30 mesh.

At this time, the step of forming the activated elastomer containing granular activated carbon having different particle sizes may be performed by the following apparatus. The apparatus described herein is merely an example of the present invention and does not exclude other examples in which the plurality of moldings described above can be formed.

Referring to FIG. 4, in one embodiment of the present invention, the activated carbon raw material tank 100 may include a discharge tube 140 through which the activated carbon molded product is discharged and an inlet tube through which the activated elastic material discharged through the discharge tube is introduced again. In addition, the activated carbon raw material tank 100 is installed in any one of the discharge pipe 140 and the inlet pipe 120 or a pump capable of moving the activated carbon molded parts connected to the discharge pipe 140 and the inlet pipe (not shown) City) or an impeller (not shown) may further include a moving part (not shown).

In addition, in one embodiment of the present invention, the activated carbon raw material tank 100 has a sieve filter 200 formed of a removable structure inside the activated carbon raw material tank 100 so as to selectively pass the activated carbon molding according to the size of the particle size. It may further include. The sieve filter 200 may be provided in plural, and each sieve filter 200 may be formed to selectively pass granular activated carbon having a particle size of a different size.

The sieve filter 200 is, for example, activated carbon containing granular activated carbon having granular activated carbon containing granular activated carbon having a particle size of 60 mesh or more and less than 30 mesh, and granular activated carbon having a particle size of 130 mesh or more and less than 60 mesh. A second filter 230 through which the molding can be passed, and a third filter 250 through which the activated carbon molded product including granular activated carbon having a particle size of 200 mesh or more and less than 130 mesh can be included.

In an embodiment of the present invention, the activated carbon raw material tank 100 may include a first accommodating part 110, a first filter 210, and a second filter between the sidewall on which the inflow pipe 120 is formed and the first filter 210. Between the second accommodating part 130 between the second accommodating part 130, the third accommodating part 150 between the second filter 230 and the third filter 250, and the sidewall on which the third filter 250 and the discharge pipe 140 are formed. The fourth accommodating portion 170 may be formed.

In the pretreatment step (S110) using the activated carbon raw material tank 100, first, the activated carbon molded article is formed in a state in which the filter network filter 200 is not mounted.

Thereafter, the first filter 210 to the third filter 250 are mounted on the activated carbon raw material tank 100 to cross the direction in which the activated carbon molding moves.

At this time, when the moving unit is activated, the activated carbon molded product of the activated carbon raw material tank 100 is discharged through the discharge pipe 140 and then flows back into the activated carbon raw material tank 100 through the inlet pipe 120 to the first filter 210. Passes through the third filter 250 sequentially.

Accordingly, the first accommodating part 110 accommodates activated carbon molded articles including granular activated carbon having a particle size of 60 mesh or more and less than 30 mesh, and the second accommodating part 130 has a next larger particle size of 130 mesh or more. An activated carbon molded article containing granular activated carbon less than a mesh is accommodated, and the third accommodating part 150 receives an activated carbon molded article including granular activated carbon having a larger particle size of 200 mesh or more and less than 130 mesh.

On the other hand, the fourth accommodating unit 170 is to stay for a while before the activated carbon molded article containing the granular activated carbon having a particle size of less than 200 mesh passes through the third filter 250 before being discharged through the discharge pipe 140. Activated elastomeric products containing granular activated carbon having a particle size of less than 200 mesh may pass through all the filter network filters 200. Therefore, the amount may remain in the first accommodating part 110 to the third accommodating part 150, but the amount thereof is extremely small.

Referring to FIG. 5, the activated carbon raw material tanks 300 and 400 of another embodiment of the present invention are shown. The activated carbon raw material tanks 300 and 400 may include a first water tank 300 and a second water tank 400.

In another embodiment of the present invention, the first water tank 300 is formed on one side, for example, the lower end of the rotary part 310 and the first water tank 300 for rotating the activated elastic molding to deposit the sediment of the first water tank 300. The first discharge pipe 320 for discharging, the second discharge pipe 330, the first discharge pipe 320 and the second discharge pipe formed on the other side of the first tank, for example, the upper end to discharge the remaining except the sediment in the activated elastomer ( 330 is formed in the connection portion is formed in the third discharge pipe 340 and the third discharge pipe 340 for discharging the activated carbon molding to the second water tank 400, the discharge valve 350 for controlling the discharge amount of the activated elastic molding It may include.

On the other hand, in another embodiment of the present invention, the second water tank 400 is located under the third discharge pipe 340 and provides a space for accommodating activated carbon.

In the pretreatment step (S110) using the activated carbon raw material tanks 300 and 400, first, the activated elastic molding is formed in the first tank 300, and then the rotating unit 310 is operated to activate the activated carbon molding in the first tank 300. Do it.

After stopping the rotating part 310 to enable the granular activated carbon of the activated elastomer is precipitated in the lower portion. At this time, each of the granular activated carbon is deposited in the lower portion of the first tank 300 according to the difference in particle size, the granular activated carbon having a larger particle size is precipitated at the bottom, and the granular activated carbon having the smallest particle size is deposited at the top. do.

When the precipitation process is completed, the discharge valve 350 is opened to allow the precipitate to be discharged to the second water tank 400 through the first discharge pipe 320 and the third discharge pipe 340, and the remaining activated elastomeric material except the precipitate is discharged. Through the second discharge pipe 330 and the third discharge pipe 340 to be discharged to the second water tank (400).

Here, since the depth of precipitation of the precipitate of the first water tank 300 is determined according to the particle size, the activated carbon molded product including the activated carbon having the desired particle size may be selectively measured by measuring the change in depth that is reduced when the activated carbon molded product is discharged. 400 can be accommodated.

At this time, the method of using the activated carbon raw material tank 100 and the method of using the first tank 300 and the second tank 400 of another embodiment in the embodiment of the present invention is different from the second tank 400 Is that the three kinds of activated elastomers disclosed in one embodiment are not simultaneously accommodated.

Meanwhile, in the adsorption step (S130), the core 20 is mounted on the molding die of the activated carbon raw material tank, and the activated carbon is vacuumed while rotating the core 20 so that the active part 40 is formed on the outer circumferential surface of the core 20. Adsorption step.

This adsorption step (S130) is a first adsorption step (S131) for adsorbing activated elastomeric products containing granular activated carbon having a particle size formed in the pre-treatment step (S110) of less than 60 mesh or more than 30 mesh, granules having a particle size of more than 130 mesh or less than 60 mesh A second adsorption step (S133) for adsorbing the activated carbon-containing article including activated carbon and a third adsorption step (S135) for adsorbing the activated carbon-form including granular activated carbon having a particle size of 200 mesh or more and less than 130 mesh.

At this time, in the case of using the activated carbon raw material tank 100 of the embodiment of the present invention in the adsorption step (S130), by moving the molding die equipped with the core 20 to the first receiving portion 110 to the third receiving portion Each of them is sequentially positioned at 150.

In addition, in the case of using the activated carbon raw material tank (300, 400) of another embodiment of the present invention, the adsorption step (S130) by dividing the step according to the size of the particle size from the first tank (300) to discharge the activated carbon molded article in the second tank ( 400 to be received, and moves the molding die equipped with the core 20 to the bottom of the second tank 400 in each step.

In this case, when the granular activated carbons included in the activated elastic molded article are not uniform in size, the activated carbon molded article having a small particle size is applied to the inside of the core 20 by blocking some of the through holes formed in the outer circumferential surface of the core 20 in the adsorption step (S130). Weakens the absorption by negative pressure. Accordingly, a problem may occur in that the thickness of the active part 40 cannot be manufactured to a desired degree. In one embodiment of the present invention to solve this problem, it is possible to configure a plurality of adsorption step so that the active portion 40 is formed to a desired thickness.

When the first adsorption step (S131) is in progress, the active portion 40 is formed by the activated carbon molding containing granular activated carbon having a particle size of 60 mesh or more and less than 30 mesh. At this time, the granular activated carbon having more than 60 mesh and less than 30 mesh has a much larger size than the through hole formed on the outer circumferential surface of the core 20, so that the through hole is not blocked by the activated carbon, so that the active part 40 can be formed to a desired thickness. In addition, the active part 40 formed in the first adsorption step (S131) serves as a skeleton that is the basis of the active part 40 formed in the subsequent adsorption step.

When the second adsorption step (S133) is in progress, the active portion 40 is formed by the activated carbon molding containing granular activated carbon having a particle size of 130 mesh or more and less than 60 mesh. At this time, the granular activated carbon having a mesh size of 130 mesh or more and less than 60 mesh fills the space between the granular activated carbon having a particle size of 60 mesh or more and less than 30 mesh adsorbed to the active part 40 in the first adsorption step (S131). Accordingly, the overall density of the active part 40 is increased while the thickness is the same or slightly increased as the active part 40 of the previous process.

On the other hand, while the granular activated carbon of 130 mesh or more and less than 60 mesh blocks the through-hole formed in the outer circumferential surface of the core 20, the suction force to suck the activated carbon is weakened, and the negative pressure applied to the inside of the core 20 increases.

When the third adsorption step (S135) is performed, the active part 40 is formed by the activated elastic molded article including granular activated carbon having a particle size of 200 mesh or more and less than 130 mesh. At this time, the granular activated carbon having more than 200 mesh and less than 130 mesh has granular activated carbon having less than 60 mesh and less than 30 mesh adsorbed to the active part 40 in the first adsorption step (S131) and the second adsorption step (S133). The space between the granular activated carbons is filled. Accordingly, the overall density of the active part 40 is increased while the thickness is the same or slightly increased as the active part 40 of the previous process.

On the other hand, through-holes formed on the outer circumferential surface of the core 20 are blocked by granular activated carbon having 130 mesh or more and less than 60 mesh and granular activated carbon having more than 200 mesh and less than 130 mesh adsorbed in the second adsorption step (S133) and the third adsorption step (S135). Adsorption power is lowered. Therefore, the negative pressure applied to the core 20 can be increased so that activated carbon molded articles including granular activated carbon having 200 or more and less than 130 mesh can be sufficiently adsorbed.

On the other hand, in one embodiment of the present invention, the active part 40, for example, 100 parts by weight of pulp contained in the activated carbon raw material tank, 90000 to 100000 parts by weight of water, 600 to 1000 parts by weight of granular activated carbon, acrylic short fiber 30 80 parts by weight, PP may comprise 50 to 150 parts by weight of short fibers.

At this time, 90000 to 100000 parts by weight of water contained in the activated carbon raw material tank exhibited an optimal state with respect to 100 parts by weight of pulp, and the water part may be formed to be 90000 or less or 100000 or more with respect to 100 parts by weight of pulp.

The active part 40 may be made of 600 to 1000 parts by weight of granular activated carbon and 30 to 80 parts by weight of acrylic short fiber with respect to 100 parts by weight of PP short fiber while being made of a structure excluding pulp.

Here, if the weight part of the granular activated carbon is limited to 1000 parts by weight or more, the product of the activated carbon filter 1 is not properly formed, and the circulation of water is not properly filtered so that the purification ability is reduced. On the other hand, if the weight part of the granular activated carbon is 600 parts by weight or less, the molding is not well made, the water does not pass through the filter, the purification ability is lowered, there is a problem that the differential pressure is increased.

In addition, the particle size of the granular activated carbon is limited to 30 mesh or more from 200 mesh or more. If the particle size of the granular activated carbon is 30 mesh or more, the differential pressure is low, the flow velocity is increased, the specific surface area is small, and the pores of the activated carbon do not adsorb impurities properly. . On the other hand, if the particle size of the granular activated carbon is 200 mesh or more, it is difficult to form and there is a problem that the differential pressure increases.

Activated carbon of 200 mesh or more is different depending on the type of activated carbon (coal-based, palm-based, charcoal-based), but it is not suitable for the manufacture of a filter for filtering a liquid object due to the problem of differential pressure.

And, when the acrylic short fibers are limited to 30 to 80 parts by weight, molding adsorption is not desired when the weight of the acrylic short fibers is 30 parts by weight or less. There was a problem involving poor pressure.

In addition, the PP short fiber is limited to 50 to 150 parts by weight, if the weight part of the PP short fiber is 50 parts by weight or less, the PP short fiber does not properly perform the role of a connecting link for fixing the components of the active part 40 to each other. If the quality is poor, and if the weight part of the PP short fiber is more than 150 parts by weight, the molded shape is poor and there is a problem involved in the differential pressure.

At this time, the active part 40 may be formed by further comprising powdered activated carbon. 90000-100000 parts of water, 300-600 parts by weight of granular activated carbon, 300-500 parts by weight of powdered activated carbon, 20-80 parts by weight of acrylic short fiber, PP short fiber 20-80 with respect to 100 parts by weight of pulp contained in the activated carbon raw material tank It may be composed of parts by weight.

Here, the limit of the granular activated carbon to 300 to 600 parts by weight is that the activated carbon filter 1 is difficult to produce when the weight of the granular activated carbon is 300 parts by weight or less, and when the weight of the granular activated carbon is 600 parts by weight or more, the specific surface area is higher than that of the powdered activated carbon. Small purification capacity fell.

In addition, the particle size of the granular activated carbon is limited to 200 mesh or more and 30 mesh or less. If the particle size of the granular activated carbon is 30 mesh or more, the differential pressure is low and the flow rate is fast, so that the activated carbon pores cannot adsorb impurities properly, and the specific surface area is small. The purification ability fell greatly. On the other hand, if the particle size of the granular activated carbon was 200 mesh or less, adsorption and surface cleanup were not easy.

And the powder activated carbon was limited to 300 to 500 parts by weight. When the weight part of the powdered activated carbon was 300 parts by weight or less, the purification ability of the activated carbon filter 1 was inferior. On the other hand, if the weight part of the powdered activated carbon is 500 parts by weight or more, the circulation of water was not smooth.

In addition, the particle size of the powder activated carbon is limited to 200 mesh or less at 300 mesh or more. When the particle size of the powder activated carbon is 300 mesh or less, the differential pressure of the filter network 200 increases and there is a risk of fire due to overheating of the circulation pump. . On the other hand, when the particle size of the powdered activated carbon is 200 mesh or more, molding adsorption is not smoothly performed, and there is a problem that the differential pressure is increased.

And the acrylic short fiber was limited to 20 to 80 parts by weight, if the weight part of the acrylic short fiber is 20 parts by weight or less, the molding adsorption was not smoothly performed, the phenomenon involved in the differential pressure occurred. On the other hand, when the weight part of the short acrylic fiber is 80 parts by weight or more, the shape of the molding is poor, there is a problem involved in the finishing work such as the melt layer forming process.

In addition, the PP short fiber is limited to 20 to 80 parts by weight, when the weight part of the PP short fiber is 20 parts by weight or less, the PP short fiber properly serves as a connection ring for fixing the components of the active part 40 to each other. If the performance was poor, the weight of the PP short fiber is more than 80 parts by weight, there is a problem that the molding shape is poor and involved in the differential pressure.

In addition, in one embodiment of the present invention, the activated carbon may be configured using any one or two or more selected from coal-based, palm tree-based, charcoal-based, and the like.

In addition, the acrylic short fibers constituting the active part 40 may be replaced with rayon short fibers, polyester short fibers, polypropylene short fibers, or the like.

Meanwhile, in the active part surface cleaning step (S200), the core 20 on which the active part 40 is formed may be removed from the activated carbon raw material tank, and the surface of the active part 40 may be evenly sucked while sucking the inner surface of the core 20. . Through this, the space formed between the activated elastomeric parts of the active part 40 as much as possible, it is possible to improve the performance of the filter.

The active part drying step (S300) is a step of drying the core 20 through the active part surface cleaning step (S200) into a drying chamber and drying at a temperature of 60 to 100 ° C. At this time, what limited the drying temperature of a drying chamber to 60-100 degreeC was that the temperature of the drying chamber was 60 degrees C or less, and the coupling | bonding and density of the raw material fell. On the other hand, when the temperature of the drying chamber is more than 100 ℃, deformation occurs on the surface of the activated carbon constituting the active portion 40, the bonding strength is lowered, there was a problem that the melt brown core to become a skeleton shrinks. In addition, there is a concern that a high temperature environment may cause a fire due to fire of carbon particles generated from activated carbon.

Figure 7 is a schematic diagram showing the formation of a melt layer on the surface of the active portion in one embodiment of the present invention.

Melt layer forming step (S400) is a step of forming a melt layer 50 made of a melted plastic of molten plastic on the surface of the active part 40 of the core 20 through the active part drying step (S300).

Referring to FIG. 7, the melt spraying part 500 forming the melt layer 50 on the surface of the active part 40 may have a hollow portion therein, and a melt spraying hole 530 may be formed at one end thereof. In addition, a melted plastic 510 such as molten polypropylene may be positioned in the inner hollow portion of the melt spraying part 500.

In one embodiment of the present invention after filling the melting plastic 510 to the inner hollow portion of the melt spraying unit 500, by applying pressure from the outside to spray the melted plastic 510 through the melt spraying hole 530, the injection The melted plastic 510 is formed on the surface of the active part 40 to form the melt layer 50 on the surface of the active part 40.

In this case, a plurality of melt spraying units 500 may be provided, and the melt spraying units 500 may be formed to face each other to simultaneously form the melt layer 50 on both sides of the active unit 40. The present invention is not limited thereto, and for example, the core 20 may be precipitated in a container in which the melted plastic is stored to form a thin melt layer 50 on the outer skin.

In one embodiment of the present invention, the melt layer 50 may be formed with a fine water hole in the process of forming and curing. Through this fine water hole, water can be primarily filtered by filtering large impurities, and the active part 40 can be protected from the outside.

Finishing step (S500) is a step of forming the activated carbon filter 1 by fitting the cap cover 60 to both ends of the core. As the finishing step S500 ends, the assembly of the activated carbon filter 1 assembly 10 is completed.
