With reference to the accompanying drawings, it will be described embodiments of the present invention to be easily implemented by those skilled in the art. As can be easily understood by those skilled in the art, the following embodiments are only intended to illustrate the present invention, and various forms without departing from the spirit and scope of the present invention. It can be modified. Where possible the same or similar parts are represented with the same reference numerals in the drawings.

All terms including technical terms and scientific terms used below have the same meaning as those commonly understood by those skilled in the art. Terms defined in advance are additionally interpreted to have a meaning consistent with the related technical literature and the presently disclosed contents, and are not interpreted in an ideal or very formal sense unless defined.

1 shows a method of manufacturing a filter according to an embodiment of the present invention in order. Filters are used to purify contaminated air or water.

As shown in Figure 1, the manufacturing method of the filter, providing a sterilizing agent (S10), providing a material for removing impurities (S20), providing a mineral material (S30), providing a binder Step S40, preparing a mixture for a filter (S50), compressing the mixture for a filter (S60), and sintering the compressed mixture (S70). In addition, the manufacturing method of the filter may further include other processes.

First, in step S10, a sterilizer is provided to sterilize the contaminated air or water. Copper zinc alloy may be used as the sterilizing agent. A powder obtained by grinding the copper zinc alloy to a particle size of 0.1 mm to 3 mm is used as a bactericide. If the particle size of the copper zinc alloy is too small, the particles are immersed in the caking agent during sintering, thereby degrading the function as a bactericide. On the contrary, when the particle size of the copper zinc alloy is too large, the particles are not combined well with other mixtures in the filter production. The composition ranges of copper and zinc contained in the copper zinc alloy can be easily understood by those skilled in the art, and thus detailed description thereof will be omitted. Copper zinc alloy removes bacteria contained in contaminated air or water.

Next, in step S20, an impurity remover is provided to remove impurities contained in contaminated air or water. Impurity removers adsorb and remove organic substances such as residual chlorine, pesticides, and carcinogens and bad odors contained in contaminated air or water. Activated carbon or the like can be used as the impurity remover. Activated carbon can be prepared by extracting from natural palm trees. For example, when water is used as drinking water, it is preferable to produce activated carbon using natural palm water which is a natural product. The natural palm tree is baked and made into activated carbon, and then pulverized into 20 mesh to 150 mesh and used as an impurity remover. If the particle size of the impurity remover is too small, it will sink in other materials during mixing, degrading the impurity removal function and generating fine dust on the surface of the filter. On the contrary, when the particle size of the impurity remover is too large, the surface of the filter is rough when the filter is manufactured, and particle dropout occurs.

In step S30 to provide a mineral material. For example, adding minerals to water can prevent arteriosclerosis and blood pressure rise. As the mineral material, a mixture of ganbanite and tourmaline may be used. These minerals can be used to provide the body with minerals that are beneficial to the body. Particulate or ball minerals may be used. The mineral material may have a particle size of 0.5 mm to 3 mm in order to increase the contact area with water.

Elvan is 1cm ³ on the surface Since it has 30,000 to 150,000 pores, it is possible to adsorb and decompose heavy metals well. Therefore, elvan can be used as a toxic metal remover. In addition, elvan rocks alkalinize the water quality by metal ion exchange, and elute minerals such as calcium (Ca) and magnesium (Mg). Tourmaline is a borosilicate with hexagonal columnar crystals and is a natural mineral belonging to the hexagonal system. Tourmaline is weakly ionized with water at pH 7.0 to pH 7.4 to release anions, refine the crust (molecular population) of water to improve the taste of water, and abundantly elute minerals such as calcium and magnesium.

As described above, it is possible to supply mineral and anionic components deficient in water by using ganbanite and tourmaline. The respective amounts of gandolite and tourmaline in the mixture containing gantherite and tourmaline can be freely controlled.

In step S40, a bactericide is provided to bind the above-described fungicide, impurity remover, and mineral feed material together. Polyethylene resin can be used as a caking additive. Polyethylene resin is not only harmless to the human body among the polymer resin, but also has a large number of pores, excellent water permeability. In addition, when the polyethylene resin is combined with the above-described bactericide, impurity remover, and mineral feed material, a filter having excellent strength can be produced.

The polyethylene resin may have a particle size of 0.1 mm to 0.2 mm. If the particle size of the polyethylene resin is too small, it is difficult to control the pore of the filter, the strength may be weakened. On the contrary, if the particle size of the polyethylene resin is too large, the contact area with the sterilizer, the impurity remover, and the mineral feed material becomes small, so that the mixing ratio of the materials is not uniform, and the bonding force between them can be weakened. Thus, the strength of the filter may be weakened.

2 is an enlarged view of one polyethylene resin particle.

As shown in FIG. 2, a number of pores are formed in the polyethylene resin particles. Polyethylene resins are good water permeability or air permeability due to these many pores. Specifically, since the porosity of the polyethylene resin is 30% by volume to 70% by volume, water permeability or air permeability is good. If the porosity of the polyethylene resin exceeds 70% by volume, air or water is dripped so well that the filter containing the polyethylene resin cannot function as the filter. On the contrary, when the porosity of polyethylene resin is less than 30 volume%, air or water does not fall well and the function as a filter is impaired.

When polyethylene resin is used as a binder, the strength of the filter is much better than when ceramic powder is used as the binder. On the other hand, natural mineral powders of kaolin and clay components can also be used as caking agents. When sintering using kaolin and clay as a caking agent at temperatures below 700 ℃, there is a lack of thermochemical reactions, which weakens the bonding strength between the materials, and the filter is in contact with water in water for a long time, so that kaolin and clay are easily separated from the water. Happens. Therefore, it is impossible to use kaolin and clay directly in the filter. On the other hand, when the polyethylene resin is used as the binder in the low-temperature sintering method of 250 ° C or less, since the filter has a sufficient bonding strength, the strength of the filter is much better than when using ceramic powder as the binder.

1, in step S50, the fungicide, impurity remover, mineral feed material, and caking agent described above are mixed together to prepare a filter mixture. The manufacturing process of the filter mixture is described in more detail with reference to FIG. 3.

3 schematically shows the cross-sectional structure of a mixing device 10 for producing a mixture for filters. The mixing device 10 may be used to mix the fungicide, impurity remover, mineral feed material, and caking agent described above together.

As shown in FIG. 3, the mixing device 10 includes a mixer 100, a heater 110, a motor 120, a power source 130, a gearbox 140, and the like. The above-described disinfectant, impurity remover, mineral feed material, and caking agent are charged to the blender 100 along the right arrow direction. After evacuating the mixer 100 in vacuo, the disinfectant, impurity remover, mineral feed material, and caking agent loaded into the mixer 100 are mixed by the feed screw 1001 rotating in the mixer 100.

Since the heater 110 is attached to the outside of the mixer 100, heat generated from the heater 110 is transferred to the mixer 100 to preheat the mixture. The operation process of the heater 110 can be easily understood by those skilled in the art, and a detailed description thereof will be omitted. The mixture is mixed uniformly while preheated to 90 ° C to 130 ° C. If the mixture is preheated to too low a temperature, there is no preheating effect, making subsequent compression processes difficult. Conversely, if the mixture is preheated to too high a temperature, the mixture may stick inside the blender 100.

Since the feed screw 1001 is sequentially connected to the gearbox 140, the motor 120, and the power supply 130, the feed screw 1001 rotates continuously by the rotation of the motor 120. The preheated filter mixture is discharged in the direction of the lower left arrow of the mixer 100.

Returning to FIG. 1, after the above-described step S50, the filter mixture preheated in step S60 is compressed. Hereinafter, the compression process of the filter mixture will be described in more detail with reference to FIG. 4.

4 schematically shows the cross-sectional structure of a compression device 20 for compressing a mixture 30 for filters. The compression device 20 can be used to compress the filter mixture 30.

As shown in FIG. 4, the compression device 20 includes a lower mold 201, an upper mold 203, and a side mold 205. Since the side mold 205 has a filter form, the filter mixture 30 can be designed in the form of a filter. The filter mixture 30 is placed on the lower mold 201 and surrounded by the side mold 205. Since the upper mold 203 is positioned on the lower mold 201, the upper mold 203 is moved in the arrow direction to compress the filter mixture 30. Therefore, the mixture for the filter compressed using the compression apparatus 20 can be manufactured.

1 again, in step S70, the compressed filter mixture is sintered at low temperature. The compressed filter mixture is sintered at 130 ° C to 210 ° C for 1 to 3 hours in a precisely controlled electric furnace. Therefore, the compressed filter mixture can be strongly bound and its strength can be increased.

If the temperature of the electric furnace is too low, sintering is poor. Conversely, if the temperature of the furnace is too high, the mixture for the filter may melt. In addition, when the sintering time is too short, the sintering is not good. On the contrary, when the sintering time is too long, not only the energy consumption is large, but also the filter mixture melts, so that the filter form cannot be maintained well.

As the mixture for the filter is heated in the electric furnace, the surface of the binder made of polyethylene resin rises and the surface thereof gradually softens. As a result. As the wettability with the bactericide surrounding the caking agent, the material for removing impurities, and the mineral material is improved, a smooth crosslinking phenomenon occurs between the compositions. Therefore, since each composition is firmly bonded, it is possible to produce a filter having excellent strength. In this case, the powder of polyethylene resin may shrink but sintered at a relatively low temperature, so that the powder state is continuously maintained. Thus the powder still has a particle size of 70% to 90% by volume. As mentioned above, the filter includes a fungicide, an impurity remover, a mineral feed material, and a caking agent, so that contaminated air or water can be efficiently purified.

On the other hand, although the ceramic powder may be used as the caking agent, the ceramic powder may not be sintered at low temperature. That is, the ceramic powder is produced by heating clay or kaolin. However, when the heating temperature is low, organic matter is present, in which case organic matter is present in the filter and the organic matter is contained in the filtered water. Therefore, it is harmful to the human body.

The purifying filter may comprise 5 wt% to 80 wt% of a binder, for example polyethylene resin. If the amount of the caking agent is too small, the fungicides, impurity removers, and mineral feed materials included in the filter may not be combined well. Therefore, the strength of the filter is weak. On the other hand, when the amount of the caking agent is too large, the amount of the disinfectant, the impurity remover, and the mineral feed material is small, so that the sterilizing effect of the contaminated air or water is lowered, the impurities cannot be removed well, and the mineral supply amount is reduced. More preferably, the filter may comprise 10 wt% to 35 wt% of a binder.

Meanwhile, the purifying filter may include 21 wt% to 90 wt% of a fungicide, for example, copper zinc alloy. If the amount of fungicide is too small, contaminated air or water cannot be sterilized efficiently. Conversely, if the amount of the disinfectant is too large, the amount of the impurity remover and the mineral feed material may be relatively lowered so that air or water may contain impurities or contain less minerals.

The purifying filter may include a mineral material of 5 wt% to 50 wt%, for example, a mixture of ganbanite and tourmaline. If the amount of mineral material is too small, it will not be able to supply enough minerals to the water, which will lower the nutrient content of the water. On the contrary, when the amount of the mineral material is too large, the amount of the disinfectant and the impurity remover is small, so that the sterilization effect of the contaminated water is lowered and impurities cannot be removed well.

In addition, the purifying filter may include 5 wt% to 50 wt% of an impurity remover such as activated carbon. If the amount of activated carbon is too small, organic matter and bad odors cannot be adsorbed. In addition, when the amount of activated carbon is too large, it is difficult to produce a filter because the cohesiveness of polyethylene resin is poor.

5 is an example of a purification apparatus employing a filter according to an embodiment of the present invention, and partially shows a cross-sectional structure of the water purifying apparatus 40. That is, the purification filter 45 manufactured by the above-mentioned method can be used for the water purifier 40. The cross-sectional structure of the water purifier 40 shown in FIG. 5 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the above-mentioned purification filter can also be used for an air purifier or a water purification device of another structure.

As shown in FIG. 5, the water purification device 40 includes a filter housing 401, a flow passage 403, a reservoir 405, and a discharge port 407. Since the gate valve (not shown) is provided in the lower part of the water purification device 40, the discharge of purified water can be freely adjusted. The filter housing 401 fixes the purifying filter 45. Since the filter housing 401 has an open / close structure, the purifying filter 45 that has reached the end of its life can be replaced. Since the opening and closing structure of the filter housing 401 can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

As shown in FIG. 5, the filter 45 can be shape | molded in plate shape. Alternatively, the filter 45 may be manufactured in a dome shape, a pipe shape, a disc shape, a dish shape, a ball shape, or the like. The filter 45 can be modified into various shapes and used in all water purification devices.

The flow path 403 connects the filter housing 401 and the reservoir 405. Water 50 flows into the purification filter 45 side through the flow path 403. The water purified by the purification filter 45 is discharged to the outside through the discharge port 407, as indicated by the arrow direction.

As shown in the enlarged source of FIG. 5, the purification filter 45 includes a caking additive 301, a bactericide 303, a material for removing impurities 305, and a mineral material 307. Here, the binder 301 has a plurality of pores 3011. Water is filled between the caking additive 301, the disinfectant 303, the material for removing impurities 305, and the mineral material 307. Although the pores 3011 are formed only in the caking agent 301 in the enlarged source of FIG. 5, a plurality of pores are also formed in each of the disinfectant 303, the material for removing impurities 305, and the mineral material 307.

As shown in the enlarged circle of FIG. 5, the caking agent 301 made of polyethylene resin has a sterilizing agent 303, a material for removing impurities 305, and a mineral material 307 through the above-described low temperature sintering process. Combine with each other. Therefore, the strength of the purification filter 45 can be maintained well. In particular, since the surface of the caking additive 301 is excellent in the wettability through the above-described low-temperature sintering process, it is adhered well to the surrounding sterilizer 303, the material for removing impurities 305, and the mineral material 307. As a result, the strength of the purification filter 45 is excellent.

In contrast to the filter according to an embodiment of the present invention, the micro filter, the hollow fiber membrane filter, the reverse osmosis filter, and the ceramic filter are complicated because the structure is a combination of four or five stages. The hollow fiber membrane filter has a limitation in removing bacteria and heavy metals, and the filtration membrane may be partially destroyed by the chlorine component contained in the water. And the reverse osmosis filter is a mineral component is removed when filtration of water, it is expensive to install the device.
