Description

{PLANAR ELEMENT FOR DEBRIS FILTER}

The present invention relates to a foreign matter filtering fabric, and more particularly, to a filter cloth for foreign matter filtration which is simple and simple in structure and manufacturing process, which reduces manufacturing cost and productivity, and can effectively remove foreign matter And which can ensure the fluidity of the fluid.

In recent years, as the harmfulness of fine heavy metal dust such as dust has appeared as a social problem, techniques have been proposed in which the filtering function of the fine dust is given to the screen net.

For example, Korean Patent No. 10-1192996 (filed on Dec. 15, 2012, see FIG. 1) discloses an insect screen installed on a window or a door, The monofilament mesh has a pore size (M) of 150 mu m or less and an open area ratio of 40 to 100 mu m. The monofilament mesh has a pore size 60%. The surface of the fiberglass is processed to have water repellency only on one surface of the fiberglass mesh which is hydrophilized by modifying the surface thereof by UV treatment after the both surfaces are water-repellent. An anti-dandruff insect screen having a diameter greater than twice that of a monofilament mesh has been proposed.

The yellow dust prevention screening network according to the above-mentioned Japanese Patent No. 10-1192996 is a method in which a fiberglass mesh and a monofilament mesh are separately manufactured and bonded to each other, so that the manufacturing process is complicated and requires a lot of manufacturing time, The surface must be modified by UV treatment on one side after double-sided water-repellent processing in order to join the mesh, so that the manufacturing process is complicated and the manufacturing time becomes too long. As a result, manufacturing costs are increased and productivity is low.

In addition, since double shielding net made of a fiberglass mesh and a monofilament mesh are bonded to each other, the aperture ratio is too low, so that there is a disadvantage that ventilation failure occurs due to difficulty in introducing outside air and indoor air.

On the other hand, in Korean Patent Registration No. 10-1191593 (registered on Oct. 10, 2012, see FIG. 2), there are shown a first insect screening network 10 and a second insect screening network 10 provided in contact with the first insect screening net 10 (20) and an ultrasonic vibration generator (30) generating vibration in the second insect control net (20), wherein the vibration of the first insect control net (10) and the second insect control net And a dust collecting function of collecting dust in the air by the generated static electricity is proposed.

The insect control network further includes a frame 1 for fixing the first insect control net 10 and the second inspecting net 20 and the frame 1 is connected to the first insect control net 10, A water injector 40 for injecting water into the insect control net 20 and a water supply means for supplying water to the water injector 40 are provided.

The insect screen according to the above-mentioned Japanese Patent No. 10-1191593 collects and removes fine dust by using static electricity, so that it is advantageous to prevent ventilation failure which is a disadvantage of the registered patent No. 10-1192996. However, the ultrasonic vibration generator 30, the insect screens are excessively complicated, and the durability of the first and second insect control nets 10, 20 is lowered due to the frequent vibration, and noise is generated.

In addition, since the insect control net according to the Japanese Patent No. 10-1191593 is equipped with the water injection device 40 and the water supply means, it is inconvenient to install, handle and use due to its too large volume and weight, .

In addition, since the insecting net according to the Japanese Patent No. 10-1191593 requires electric energy for the operation of the ultrasonic vibration generating device 30 and the water injecting device 40, the maintenance cost is increased.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 3 to 13, and the same reference numerals are given to the same constituent elements in FIG. 3 to FIG. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

FIG. 3 is a perspective view showing a foreign matter filtering fabric according to a first embodiment of the present invention. In this drawing, an enlarged portion shows a part of a foreign matter filtering fabric in an enlarged view, do.

Referring to FIG. 3, a foreign matter filtering raw fabric according to the first embodiment of the present invention includes a face mask for preventing foreign substances such as dust contained in air from entering the human body, a screen mask installed on a window to prevent foreign substances from entering the room, And can be used as an industrial filter for blocking the inflow of foreign matter into the interior of the apparatus, the curtain fabric, the machine, and the apparatus. The filter layer 11 is composed of the inner filtration layer 11, the outer filtration layer 12 and the connection layer 13.

The inner filtration layer 11 is formed of a weft yarn (a, which means a shoe arranged in the lateral direction) and a warp yarn and the outer filtration layer 12 is spaced apart from the inner filtration layer 11 by a spacing space 14, And the connecting layer 13 is formed by a plurality of connecting yarns c so as to be connected between the inner filtering layer 11 and the outer filtering layer 13 in the spacing space 14. [

At least one of weft (a), warp (b) and connecting yarn (c) forming the inner filtration layer (11) and the outer filtration layer (12) So that static electricity is generated by friction while moving against an external force such as a pressure generated when a fluid such as air flows.

In this embodiment, the weft yarns a and b forming the inner filtration layer 11, the weft yarns a and b forming the outer filtration layer 12, and the connecting yarn c are And are formed of different materials.

For example, the inner filtration layer 11 is woven in a lattice pattern so as to have openings by applying a warp yarn having a diameter of 1000 탆 or less coated with a PVC resin on the outer surface of a glass fiber yarn or a ceramic fiber yarn as weft yarns and warp yarns.

The outer filtration layer 12 is woven in a grid pattern by applying a synthetic monofilament yarn having a diameter of 500 mu m or less as a weft yarn and a warp yarn to easily generate static electricity. For the synthetic monofilament yarn, PET monofilament yarn or polyolefin monofilament yarn is applied.

The connecting yarn (c) is composed of a high-tension fiber yarn so as to ensure sufficient durability against repetitive movement of the outer filtration layer (12). High tenacity fiber yarn is named as aramid fiber yarn (DUPONSA) or tensile strength of 20 g / d (denier) or more, deterioration temperature of 250 DEG C or more, thickness of 10 to 2,000 denier, and Kevlar yarn Based aramid fiber yarn.

In addition, the connecting yarn (c) may be formed of elastic monofilament yarn so that the outer filtration layer 12 can be moved toward the inner filtration layer 11 to be contacted and then returned. At this time, the elastic monofilament yarn may be composed of a core portion disposed along the longitudinal direction at the center so as to have sufficient elasticity, and an outer skin covering the outer portion of the core portion.

For example, the core portion may be formed by applying a metal yarn having an outer diameter of about 20 to 100 mu m, or by using any resin selected from a polyester resin, a polyester copolymer resin, or a mixed resin thereof, .

As described above, when the connecting yarn (c) is applied as the elastic monofilament yarn, the outer filtration layer (12) is moved to the inner filtration layer (11) As a result, the number of times of friction increases, and the generation of static electricity is effectively performed, thereby improving the removal efficiency of the foreign matter.

The outer layer 12 and the inner filtration layer 11 have different mesh densities from each other. The weaving density of the foreign matter filtering fabric can be realized by controlling the arrangement interval of the weft and the warp in the process of weaving the inner filtration layer 11 and the outer filtration layer 12 using a weaving machine. In this embodiment, As shown in the enlarged part, the mesh density of the outer filtration layer 12 from which foreign matter is filtered is formed to be dense.

More specifically, the inner filtration layer 11 is formed so as to have an open area ratio of about 80% and a outer filtration layer 12 of about 70% and about 5%, respectively. In this case, the hole area ratio can be calculated by the aperture ratio calculation formula (aperture ratio (%) = M ² / (M + D) ² ) in relation to the diameter (D) of the weft and slope and the opening size (M). Here, the pore size M means the distances d1 and d2 between the monofilament yarns woven as shown in Fig.

In the meantime, the fabric for filtering foreign materials according to the present invention has an insulating material (the insulating material is a concept including a non-conductive material) inside the material for filtering foreign matter which can come into contact with the human body so as not to adversely affect the human body when the static electricity is generated .

For example, an insulating sheet formed of an insulating material and having air permeability may be additionally disposed in the inner filtration layer 11, but the weft yarns a and b forming the inner filtration layer 11 are formed as insulating shafts It is convenient. In this case, the inner filtration layer 11 may be formed by coating a rubber-based resin having insulating properties with a fiber yarn.

When the inner filtration layer 11 is formed as an insulating jacket, it is prevented that current is supplied to the human body at the time of generation of static electricity, so that static electricity is not generated at the time of contact so that adverse effects on the human body can be fundamentally prevented. Generally, even if static electricity is generated, the voltage is high but the current is very small and the energization time is very short and the effect on the human body is small. However, this problem can be fundamentally solved considering that the degree of response to electric stimulation is different for each individual.

4 is a perspective view illustrating a first modified example of a foreign matter filtering fabric according to the first embodiment of the present invention.

Referring to FIG. 4, the foreign matter filtering fabric has an inner filtration layer 11 woven in a plane by weft and warp, a space 14 spaced from the inner filtration layer 11, (13) formed by a plurality of connecting yarns (c) arranged to be connected between an inner filtration layer (11) and an outer filtration layer (12) in a spacing space (14) , And the outer filtration layer 12 or the inner filtration layer 11 is formed with a cut-off portion e.

The cut part e is formed by cutting the outer filtration layer 12 or the inner filtration layer 11 by a cutter. When the cut part e is formed, when the pressure of the fluid such as the wind is applied, The portion cut by the portion (e) becomes more free to move, and the generation of static electricity becomes more active, so that the removal efficiency of the foreign matter is improved.

FIG. 5 is a perspective view showing a second modified example of the foreign body filtering fabric according to the first embodiment of the present invention, and shows a simplified part of the sectional structure.

Referring to FIG. 5, the foreign matter filtering fabric has an inner filtration layer 11 that is woven in a plane by weft and warp, a separation space 14 from the inner filtration layer 11, (13) formed by a plurality of connecting yarns (c) arranged to be connected between an inner filtration layer (11) and an outer filtration layer (12) in a spacing space (14) And a part of the connecting yarn c constituting the connection layer 13 is cut so that the outer filtration layer 12 or a part of the inner filtration layer 11 can be moved. Respectively.

When a part of the connecting yarn c constituting the connecting layer 13 is cut, when the fluid pressure such as wind is applied, the outer filtration layer 12 or the inner filtration layer 12 of the cut connecting yarn c, (11) is freed to move freely, so that the frictional action between them is vigorously performed, and as a result, the generation of static electricity becomes active and the removal efficiency of the foreign matter is improved.

FIG. 6 is a perspective view showing a third modified example of the foreign body filtering fabric according to the first embodiment of the present invention, showing only one side edge portion.

Referring to FIG. 6, the foreign matter filtering fabric has a weft yarn a forming an inner filtration layer 11 and an outer filtration layer 12, and a static electricity generated by friction between a warp yarn b and a connecting yarn c An insulating connection portion 19 is formed in which the edge portion of the fabric for filtering foreign matters is insulated with an insulating material (nonconductive) so that the fabric can be easily charged to the outside or static electricity can not be removed.

In addition, when the fabric for filtering foreign matters according to the present invention is cut into a size of an insect screen installed on a window to be used as an insect screen, when the insect screen frame (not shown) is made of metal, a static electricity field formed by friction is unnecessarily If the insulating connection portion 19 is formed on the outer surface of the foreign substance filtering member, the static electricity is not discharged to the surroundings even if they are connected to each other.

In addition, the spacing space 14 between the inner filtration layer 11 and the outer filtration layer 12 may be filled with a filler (not shown). At this time, the filling material (not shown) may be selected and inserted with functional materials such as tourmaline (tourmaline) or charcoal particles that emit far-infrared rays. In this embodiment, however, a plurality of fine filament yarns are swollen so as to remove fine dust A thick yarn of thick thickness can be built in.

Hereinafter, a second embodiment and a third embodiment according to the present invention will be described. However, a detailed description of constituent elements similar to those of the first embodiment and its modifications will be omitted, Explained mainly. In the following second and third embodiments, any of the constituent elements shown in the first embodiment and its modifications and the like can be selectively applied, so that a detailed description thereof will be omitted.

FIG. 7A is a perspective view showing a fabric for filtering foreign matters according to a second embodiment of the present invention. FIG. 7B is a schematic view showing an example of a static electricity generator applicable to a foreign matter filtering fabric according to a second embodiment of the present invention. And FIG. 7C is an exploded perspective view illustrating an electrostatic generating module of a static electricity generator applicable to a foreign matter filtering fabric according to a second embodiment of the present invention. Although only a conductive line 1 constituted by the discharge electrode 22 is exaggeratedly shown in the accompanying drawings and the illustration of the ship building constituting the insect screen is omitted, it should be understood that it is simplified and emphasized in part to facilitate understanding of the invention.

7A to 7C, the foreign matter filtering fabric according to the second embodiment of the present invention may have an inner filtration layer 11 that is woven in a plane by weft and warpage, and a separation space from the inner filtration layer 11 (C) spaced apart and arranged to connect between the inner filtration layer (11) and the outer filtration layer (12) in the spaced space and an outer filtration layer (12) that is woven in a plane by weft and warp, And a connection layer 13 formed on the connection layer 13. The static electricity generating device 2 is further provided on the fabric for filtering foreign matters and removes fine dust using static electricity.

The static electricity generating device 2 is a component for causing fine dust to be attracted by artificially inducing static electricity on the foreign substance filtering raw material, and includes a static electricity generating module 21 for generating a static electricity generating potential, And a discharge electrode (22) for applying the generated electrostatic potential.

Here, when the electrostatic generating device 2 according to the present invention is formed of monofilament yarn which is charged at the time of application of the electrostatic field, since the foreign substance filtering fabric itself performs the function of the whole of the electrostatic field generating module 2, The acceleration electrode 23 may be further provided as in the following modification example.

The discharge electrode 22 is disposed in the inner filtration layer 11, which is the inside of the material for filtering foreign matter, and is composed of a conductive line 1 capable of conducting current. Considering that fine dusts such as floating dust and heavy metal particles have a positive potential, the discharge electrode 21 has a static electric potential (that is, a high voltage (negative)) having a negative potential at the dust collection site, (-) potential from the electrostatic generating module 21 so as to form the electrostatic discharge generating potential (positive potential).

FIGS. 8A to 8C are views showing examples of conductive lines usable as the discharge electrodes of the foreign substance filtering raw material according to the second embodiment, and are perspective views in which a part of the conductive lines are enlarged.

Referring to Figs. 7A to 8C, the discharge electrode 22 is made of a conductive wire, which is a conductive wire.

The conductive line 1 is arranged so as to have a plurality of bent portions as shown in FIG. 7A so as not to be broken or damaged even if tensile force is applied to the foreign substance filtering cloth. At this time, the bent portion is formed to have a substantially sinusoidal waveform structure.

The conductive line 1 may be formed using only a conductive sheath capable of conducting current, such as a copper wire. In this embodiment, in addition to the fibers forming the inner and outer filtration layers, 1) is supplied to the weaving machine (not shown) to be woven or the conductive line 1 is supplied to the embroidery yarn supply part of the embroidery machine (a kind of loom forming a pattern on the weaving fabric, not shown) It is supposed to have characteristics similar to fiber yarn because it should be woven.

For example, as shown in Fig. 6A, the conductive wire 1 has a core yarn 11, a conductive yarn 12 disposed on the outer surface of the core yarn 11, and an outer sheath (not shown) disposed on the outer surface of the conductive yarn 12. [ l3) are sequentially wound.

The center yarn 11 is formed of a fiber yarn so as to satisfy the flexibility, and has a fineness ranging from 5 to 2000 denier. Here, when the fineness of the core yarn 11 is 5 denier or less, the thickness of the core yarn 11 is too thin to make it difficult to wind the conductive yarn 12 and have a sufficient tensile strength. When the fineness of the core yarn 11 is 2,000 denier or more, Which is excessively thick, leads to an increase in the overall thickness of the conductive wire 1, resulting in a decrease in flexibility and a deterioration in the straightness of the wire. Here, 1 denier means the thickness when 1 gram of fiber material is drawn at 9000 meters.

The conductive yarn 12 is disposed in conjunction with the center yarn 11 and arranged so that at least one strand is woven or wound around the outer surface of the core yarn 11. [

The reason why the diameter of the conductive metal sheet is applied as the conductive material 12 is that at least one conductive metal sheet is included so that the total diameter of the conductive wire 1 is 1000 micrometers or less So that it can be smoothly supplied to the loom and woven.

When the diameter of the electric conductor 12 is 500 micrometers (탆) or more, it is difficult to weave. Conductive metal wires of 10 micrometers (㎛) or less are difficult to be massively produced by current production technology, , This embodiment applies an insulated coated copper wire having a diameter in the range of 20 to 100 micrometers (占 퐉) that has proven its conductivity, durability and quality.

The envelope yarn 13 may be arranged in such a manner that it is woven on the outer surface of the conductive yarn 12 as a preheating yarn arranged to be superposed on the outside of the conductive yarn 12. In this embodiment, as shown in Fig. 7A, As shown in Fig.

7B, the center line 11 and the center line 11 are wound in a coil shape so that the conductive line 1 can be extended to an external load such as a tensile force applied to the foreign material filtering cloth It is possible to apply the constitution made of the electric conductor 12. At this time, the core yarn 11 is composed of a stretchable polymer yarn called spun yarn, polyurethane yarn or the like.

The conductive line 1 is composed of a conductive material 11 disposed at the center as shown in Fig. 8C and an outer covering layer l5 laminated on the outside of the conductive material l1. At this time, a conductive metal yarn having a diameter in the range of 10 to 500 micrometers (mu m) is applied to the electric conductor 11, and a PET resin is selected and coated in the outer skin layer 15 for smooth generation of static electricity.

The conductive line shown in FIG. 8C has a smooth outer surface coated with a resinous material, so that it can be easily wiped off when foreign matter is piled up excessively, thus facilitating cleaning.

The power unit 211 may be selected from at least one of a primary battery such as a straight type or coin type battery, a secondary battery such as a rechargeable battery, and a DC power supply connected to a commercial power source. In FIG. 7C, And a battery is incorporated therein.

The voltage conversion control unit 212 is a component that receives power from the power supply unit 211 and controls the high voltage conversion required for forming the electrostatic generated potential. The electrostatic generating potential formation unit 213 is a unit And a static electricity generating potential is formed by the high voltage and applied to the discharge electrode 22. Here, detailed configurations of the voltage conversion control unit 212 and the electrostatic generating potential formation unit 213 are the same as those applied to the conventional electrostatic generating apparatus, and a detailed description thereof will be omitted.

The electrostatic generating module 21 further includes a switch unit 214 for interrupting power supplied from the power supply unit 211 to the voltage conversion control unit 212. For example, the switch unit 214 is constituted by installing a switch having a plurality of switching contacts in the case 24. [

The case 24 includes a first case 241 in the form of a circular cap in which a static electricity generating module and a power supply unit are incorporated and is provided with a switch unit 214 and a lead-out hole through which a terminal or the like for connecting the discharge electrode is drawn out, And a second case 242 in the form of a circular cap provided with a terminal of a connector.

According to this, even if a large amount of fine dust is adsorbed on the foreign material filtering cloth due to long use, it can be easily removed without performing a separate washing operation or the like for removing it, so that the convenience of use is further improved.

Referring to FIG. 9B, a foreign matter filtering fabric according to a modification of the present invention further comprises an self-generating device 7 for generating a current for the operation of the electrostatic generator 2 itself.

The accelerating electrode 23 is disposed on the outer side of the foreign material filtering raw material opposite to the discharging electrode 22 so that fine dust is rapidly (+) Potential (that is, the base potential) of the low voltage is applied from the static electricity generating module 21 in order to effectively adsorb it. In other words, the accelerating electrode 23 is applied with a positive potential at a low voltage in the process of forming a static electric field by applying a negative potential from the discharging electrode 22, so that the collecting portion is charged to a stronger negative potential And performs a function of accelerating so that the bipolar dust having a polarity is adsorbed more rapidly. That is, the accelerating electrode 23 can remove the fine dust even if only the discharging electrode 22 is provided in the electrostatic generator 2, but added for the quicker and more effective removing action.
