Description

A filter device including a filtering unit including a permeable blade and a drainage system including the same

The present invention relates to a filter device and a drainage system including the same. In detail, it relates to a drainage filter device and a drainage system including a rotary filtering unit including water permeable blades, and a method for alarming replacement time of a filter device using the same.

Conventionally, micro-plastics may be defined as micronized synthetic polymer materials of 5 mm or less. Microplastics are recognized as a great threat to the marine ecosystem because they take a considerable amount of time to decompose naturally, and recently, problems caused by microplastics are becoming more issues in relation to environmental problems.

Microplastics accumulate throughout all stages of the marine food chain, such as in fish and marine mammals. Accordingly, UNESCO has selected microplastic reduction as a major issue in the field of marine ecosystem health protection. Microplastics that have flowed into the ocean not only cause direct damage to animals and plants that make up the marine ecosystem, but also accelerate the destruction of the ecosystem as the amount accumulates. Even recently, a significant concentration of microplastics has been found in drinking water that people drink, causing a big problem.

According to a recent report on the causes of microplastics by the Dutch National Institute of Public Health and Environment (RIVM), synthetic fiber fabrics and clothing rank high. In this way, among microplastics, especially those generated from fiber products are also referred to as micro-plastic fibers or micro-fibers (fine fibers).

The length of plastic fibers used in the manufacture of clothing varies from several nanometers (nm) to several millimeters (mm) and even tens of millimeters. Plastic fibers are physically weathered during repeated use and washing and can form small-sized microplastics. Other studies have reported that thousands of microplastic fibers are released when one garment is washed once.

In case the fine plastic fibers generated from the clothes during the washing process are not filtered out and drained as they are, the aforementioned problems may occur. Therefore, there is an urgent need to develop a technology for reducing microplastic fibers, for example, a technology for collecting microplastic fibers generated when washing clothes at home.

As a method for collecting fine plastic fibers in drain water, it may be considered to provide a drain filter having a mesh structure or a porous structure to the drain flow path (or drain pipe) of the washing machine. Filtering can be performed by using the size of the mesh to block penetration of foreign substances having a larger size than the mesh.

When the filtered microplastics remain in the filter device as the filtration is repeated, the mesh or pores are gradually blocked, causing a decrease in the permeation flow rate and a so-called filter clocking phenomenon in which the permeation pressure greatly increases. That is, when the lifespan of the filter device is exhausted, differential pressure between the flow passages before and after the filter device may occur. If the filter device is not replaced despite the lifespan of the filter device being exhausted, problems such as bursting of the filter, malfunction of the washing machine, or reverse flow of drainage may occur due to differential pressure in the passage. Moreover, since the washing machine is generally not close to a person's circulation, it is not easy to frequently check the replacement time of the filter device. The above problems act as a factor hindering the popularization of drain filters for washing machines.

Accordingly, an object of the present invention is to provide a filter device having a new structure capable of preventing generation of differential pressure even when the life of the filter device is exhausted. Furthermore, it is an object of the present invention to provide a filter device capable of notifying the replacement time of the filter device in an easy way.

Another problem to be solved by the present invention is to provide a drainage system using the above filter device.

Another problem to be solved by the present invention is to provide a method for providing replacement time information of the filter device.

Another problem to be solved by the present invention is to provide a computing device capable of informing replacement time information of the filter device.

The tasks of the present invention are not limited to the technical tasks mentioned above, and other technical tasks not mentioned will be clearly understood by those skilled in the art from the following description.

A filter device according to an embodiment of the present invention for solving the above problems includes a housing having an inner space; and a filtering unit rotatably disposed within the housing, including a rotating shaft and one or more water-permeable blades arranged in an outer circumferential direction of the rotating shaft.

The water permeable blade may include a mesh structure, a porous film, a porous membrane, or a porous plate.

Alternatively, the water permeable blade may include a plate arranged in an outer circumferential direction and a plurality of barbed fibers protruding from the plate.

The extending direction of the barbed fiber may be parallel to the tangential direction of the rotating end surface of the rotating shaft part, or a direction forming an intersection angle with the tangential direction within 30°.

In addition, the barbed fiber may include an extended fiber body and a plurality of branches protruding from the fiber body.

At this time, at least some of the branches may have an inclination to form an acute angle toward a direction opposite to the flow direction of the fluid flowing along the inside of the housing.

The plate may have one or more passage holes, and at least a part of the fluid flowing along the housing may pass through the passage holes.

In addition, the filtering unit may be configured to be rotatable by a fluid flowing along the inside of the housing.

In some embodiments, the filter device may further include a sensor for detecting a rotational speed, a rotational direction, or an accumulated number of rotations of the filtering unit.

A drainage system according to an embodiment of the present invention for solving the above other problems includes a fluid inlet pipe and a fluid outlet pipe; and a filter device fluidly coupled between the inlet pipe and the outlet pipe, wherein the filter device is a housing having an inlet and an outlet, wherein the inlet is connected to the inlet and the outlet is connected to the outlet. and a filtering unit rotatably disposed within the housing, the filtering unit including a rotating shaft and a plurality of water-permeable blades arranged in an outer circumferential direction of the rotating shaft.

In order to solve the another problem, a method for providing a filter device replacement time or an alarm method according to an embodiment of the present invention includes a filter device replacement time including a housing and a filtering unit rotatably disposed in the housing. An information providing method, which is performed by a computing device including at least one processor, receives information on a rotational speed or accumulated rotational speed of a filtering unit, and compares the rotational speed or accumulated rotational speed with a predetermined reference value. and providing information about the replacement alarm of the filter device.

A computing device according to an embodiment of the present invention for solving the above another problem is related to the rotational speed or accumulated rotational speed of the filtering unit from a filter device including a housing and a filtering unit rotatably disposed in the housing. Rotation amount collection unit receiving the information; a determining unit comparing the collected amount of rotation with a predetermined reference value; and an alarm unit providing information on a replacement alarm according to a result of the determination of the determination unit.

Other embodiment specifics are included in the detailed description.

According to embodiments of the present invention, a filter device capable of filtering out microplastics may be installed in a drain passage, for example, a drain passage of a washing machine, to filter microplastics or other particulate matter in drainage such as wash water. .

In addition, even when the lifespan of the filter device is exhausted, problems such as bursting of the filter device or reverse flow of drainage can be prevented in advance by suppressing an increase in permeation flow rate or an increase in differential pressure in the passage. For example, when the passage space of the water-permeable blade is sufficiently clogged with microplastics to no longer exhibit filtering ability, the filtering unit may be configured to rotate rather than exhibit the filtering properties of the microplastics.

That is, according to the present invention, it is used to collect microplastics during the lifespan of the filter device, but when the lifespan is over, the filtering capacity is automatically lowered and it is possible to ensure that the filter device does not explode. Of course, when the lifespan of the filter device is exhausted, it is impossible to sufficiently collect the microplastics, but considering the problem of the filter device bursting, the effect of reducing the microplastics can be shown compared to the case where the filter device is not installed at all.

In addition, the life of the filter device can be estimated or measured by a relatively simple method such as measuring the amount of rotation of the rotational filtering unit, for example, the rotational speed and / or the cumulative number of rotations, rather than a complicated method such as measuring the differential pressure, This can be used as information for alarming the replacement time of the filter.

Effects according to the embodiments of the present invention are not limited by the contents exemplified above, and more diverse effects are included in the present specification.

1 is a schematic diagram of a drainage system using a filter device according to an embodiment of the present invention.

Referring first to FIG. 1 , the drainage system 1 according to the present embodiment may include a washing machine 20 having a washing tub and a drain pipe 10 fluidly connected to the washing machine 20 .

The washing machine 20 may include a washing machine for washing textiles or laundry. The washing machine 20 may include a washing tub in which laundry is put into and washing is performed. Although FIG. 1 illustrates a laundry drainage system as a drainage system, it goes without saying that the present invention is not limited thereto. In another embodiment, the drainage system 1 and the filter device 11 may be applied in an industrial drainage system.

The drain conduit 10 is fluidly connected to the washing tub and may provide a fluid path through which liquid such as wash water, drainage, or waste water discharged after washing the laundry is discharged. The drain conduit 10 includes the first conduit part 10a (or the fluid inlet pipe), the second conduit part 10b (or the fluid outlet pipe) and the fluid path on the first conduit part 10a and the second conduit part ( 10b) may include a filter device 11 positioned between them. That is, the first conduit part 10a connects the washing tub and the filter device 11 to provide a fluid path, and the fluid passing through the filter device 11 can be completely discharged through the second conduit part 10b. . Although not shown in the drawing, in another embodiment, the first conduit part 10a, the second conduit part 10b, and/or the filter device 11 are not connected to the outside of the washing machine 20, but the washing machine ( 20) may be provided inside. Alternatively, the first conduit portion 10a and/or the second conduit portion 10b may be omitted.

Hereinafter, the filter device 11 according to the present embodiment will be described in more detail. FIG. 2 is a perspective view of the filter device of FIG. 1, in which the interior is projected. 3 is a cross-sectional perspective view of the filter device of FIG. 2; Fig. 4 is a cross-sectional side view of the filter device of Fig. 2; Fig. 5 is a perspective view of a filtering unit of the filter device of Fig. 2;

2-5 , the filter device 11 may include a housing 100 having a fluid inlet 121h and a fluid outlet 122h and a filtering unit 200 disposed within the housing 100. there is.

The housing 100 may be a part forming the exterior of the filter device 11 . The housing 100 may have an internal space through which a fluid may flow. The housing 100 may include a housing body 110 and a first coupling part 121 and a second coupling part 122 disposed at both ends of the housing body 110 . The housing body 110, the first coupling portion 121, and the second coupling portion 122 may be integrally formed without a physical boundary. The housing 100 may be made of polycarbonate resin or the like, but the present invention is not limited thereto. The housing 100 may be partially made of a transparent material so that the filtering unit 200 therein is visible.

The first coupling portion 121 may form a fluid inlet 121h (or first fluid outlet), and the second coupling portion 122 may form a fluid outlet 122h (or second fluid outlet). The first coupling portion 121 and the second coupling portion 122 may be means for coupling with the first conduit portion 10a and the second conduit portion 10b, respectively. For example, each of the first coupling portion 121 and the second coupling portion 122 may have threads formed on the outer or inner circumferential surfaces thereof, but the present invention is not limited thereto. The fluid introduced through the first conduit part 10a may flow into the inner space of the housing body 110 through the fluid inlet 121h. In addition, the fluid flowing out of the inner space of the housing body 110 through the fluid outlet 122h may flow into the inner space of the second conduit part 10b. Fluid introduced through the fluid inlet 121h and discharged through the fluid outlet 122h may form a fluid path substantially in the first direction X within the housing body 110 . That is, as known, the fluid flowing along the flow path may form various flows such as forming vortexes, but the main fluid flow path within the housing body 110 may be approximately in the first direction (X).

The filtering unit 200 may be disposed in the inner space of the housing body 110 . The filtering unit 200 may be disposed on the main flow path of the fluid flowing therethrough. For example, the filtering unit 200 may be located on a line connecting the first coupling portion 121 and the second coupling portion 122 and/or the fluid inlet 121h and the fluid outlet 122h. there is.

The filtering unit 200 may include a rotation axis portion 210 forming a rotation axis and a plurality of blades 230 disposed on the rotation axis portion 210 .

The rotating shaft 210 may include a rotating shaft. The filtering unit 200 may be configured to be rotatable using the housing 100 and the rotating shaft 210 rotatably fixed. At this time, the filtering unit 200 may be configured to rotate within a plane to which the aforementioned main flow direction of the fluid, that is, the first direction (X) belongs. This embodiment illustrates a case in which the filtering unit 200 rotates within a plane to which the first direction (X) and the third direction (Z) belong. In this case, the filtering unit 200 may be expressed as rotating in at least a first direction (X) or rotating in at least a third direction (Z). On the other hand, it can be understood as not rotating in at least the second direction (Y). The rotating shaft 210 has a shape extending in the second direction (Y), and the third direction (Z) may be a direction parallel to the direction of gravity, but the present invention is not limited thereto.

The blade 230 may be a means for directly filtering microplastics or other particulate impurities included in the fluid flowing along the inside of the housing 100 . To this end, the blade 230 may have a predetermined permeability. In addition, any one blade 230 may have a filtering function itself. That is, the blade 230 may be a water-permeable-filtering blade. For example, although not represented in the drawing, the blade 230 may include a mesh structure or a network, and a frame supporting the mesh structure. At this time, the mesh structure has a plurality of fine pore structures, and may exhibit water permeability through the pores. At the same time, the pore size can be used to filter materials larger than the pore size. As a non-limiting example, the mesh structure of the water permeable blade 230 may be configured to filter fine particles that are several micrometers, or tens of micrometers, or hundreds of micrometers, or several millimeters in size.

In another embodiment, the water permeable blade 230 may include a porous water permeable film, membrane, plate, or the like.

On a cross section cut in the first direction (X) or the third direction (Z), that is, on the rotational end face of the filtering unit 200, the plurality of blades 230 may be arranged to extend in the outer circumferential direction of the rotation shaft portion 210. there is. The outer circumferential direction may refer to a substantially radial direction based on the rotation center of the rotating shaft portion 210 . For example, the blade 230 may be arranged to extend in a direction perpendicular to a tangent of the surface of the rotating shaft 210, that is, in a normal direction. In addition, the plurality of blades 230 may be rotated at a predetermined angle with respect to the center of rotation. Accordingly, the filtering unit 200 may have a shape similar to that of a waterwheel. 3 and the like illustrate a case in which 12 blades 230 are disposed, but the present invention is not limited thereto.

The blade 230 may extend in the second direction (Y) to form a predetermined occupied area. The area occupied by one of the blades 230 may be understood as a permeable surface or a filtering surface. The permeable surface and/or the filtering surface may be perpendicular to a rotational plane of the filtering unit 200 (ie, a plane to which the first direction X and the third direction Z belong).

The water-permeable surface formed by the blade 230 may vary depending on the position of the blade 230, but, for example, the water-permeable surface of the blade 230 in the 12 o'clock direction and 6 o'clock direction (based on the drawing) showing the maximum fluid flow resistance It may substantially coincide with the plane to which the second direction (Y) and the third direction (Z) belong. For another example, the water-permeable surfaces of the blades 230 at the 3 o'clock and 9 o'clock directions representing the minimum fluid flow resistance may substantially coincide with the planes to which the first direction (X) and the second direction (Y) belong.

In some embodiments, filter device 11 may further include a sensor unit 300 and/or a communication unit 400 .

The sensor unit 300 may be a means for measuring the amount of rotation of the filtering unit 200 , specifically, the rotating shaft unit 210 . In this specification, the term rotation amount may be used as a concept including rotation speed, rotation direction, and/or accumulated rotation number.

In addition, the communication unit 400 may include a baseband circuit for processing wired/wireless signals. For example, the communication unit 400 is a mobile communication network such as code division multiple access (CDMA), wide band code division multiple access (WCDMA), high-speed packet access (HSPA), long term evolution (LTE) or Ethernet, Data may be transmitted and received using a wired communication network such as digital subscriber line (xDSL), optical coaxial network (HFC), and optical subscriber network (FTTH), but the present invention is not limited thereto.

Although not represented in the drawings, the filter device 11 may further include a processor and/or a speaker. The processor may implement operations and functions so that the communication unit 400 may transmit a result measured by the sensor unit 300 . Alternatively, an alarm may be provided through a speaker based on a result measured by the sensor unit 300 . Power for the operation of the sensor unit 300, communication unit 400, speaker and/or processor of the filter device 11 may be supplied from a battery (not shown) or may be supplied from the washing machine 20 or the like. may be In some embodiments, the filter device 11 may further include memory and/or storage to implement operations by the processor.

Hereinafter, the operation of the filter device 11 according to the present embodiment will be described in detail. 6 is a schematic diagram showing a filter device in a state in which the life of the filter device remains, for example, in a state in which there is no or relatively little microplastic collected on the blade 230. 7 shows the filter device in a state in which the life of the filter device is exhausted, for example, a relatively large amount of microplastics collected in the blades 230 or a cloaking phenomenon occurs because at least some of the blades 230 are blocked. It is a schematic diagram shown.

First, further referring to FIG. 6 , the fluid flowing along the inside of the housing 100, specifically, the inside of the housing body 110 is filtered by the water permeable surface (or filtered) formed by the plurality of water permeable blades 230 of the filtering unit 200. side) can pass through. In the process, microplastics (or microfibers) MF included in the fluid may be filtered and collected by the mesh structure of the blade 230 .

As a non-limiting example, the filtering unit 200 may rotate counterclockwise based on FIG. 6 . This may be because the third direction Z is parallel to the direction of gravity, so that the flow of fluid is concentrated to the lower side of the filtering unit 200, but the present invention is not limited thereto. In another embodiment, the second direction (Y) may be substantially parallel to the direction of gravity.

In this state, the filter device 11 exhibits excellent microplastics collection efficiency and can contribute to reducing microplastics in the discharged fluid. In addition, the microplastics (MF) filtered through the mesh structure of the blade 230 block a part of the pores of the mesh structure, but can still show a sufficient amount of water permeation, so that the filtering unit 200 does not substantially rotate or relatively It can rotate at a small speed. That is, despite the flow of the fluid, the fluid may flow through the blade 230 rather than rotating the filtering unit 200 .

On the other hand, further referring to FIG. 7 , as the filter device 11 continues to be used, the microplastics (MF) filtered through the blades 230 may block most of the pores formed by the mesh structure. Accordingly, the water permeability of the water permeable surface (or filter surface) formed by the blade 230 may be reduced. That is, the flow of fluid may rotate the filtering unit 200 rather than passing through the blades 230 . Therefore, in this state, the filtering unit 200 may rotate at a relatively high speed compared to the previous case.

Unlike the present invention, if a mesh having a fixed position and shape is used as a filter device, a differential pressure is generated on the fluid path in the front and rear of the mesh as the microplastic filtered through the mesh accumulates, and the differential pressure is excessively large, resulting in the permeation of the fluid. If it becomes difficult, in other words, if a cloaking phenomenon occurs in the filter, the filter device may explode. However, in the filter device 11 according to the present embodiment, the permeation of the fluid acts predominantly in the initial state to perform the filtration of the microplastics, but when the pores are blocked to the extent that the permeation of the fluid becomes difficult, the filtering surface is rotated. By configuring it, the flow of the fluid can not be blocked, and the formation of differential pressure can be suppressed in advance. Therefore, even if the user does not recognize that the life of the filter device 11 is exhausted, it is possible to prevent the filter device 11 from exploding.

In addition, when the filter device uses a mesh having a fixed location and shape as in the prior art, the life of the filter device is limited because only a filter surface having a limited fluid cross-sectional area is provided. In addition, even when a plurality of meshes are arranged in series, there is a problem in that a differential pressure occurs in the entire filter device when any one mesh is blocked. However, the filter device 11 according to the present embodiment provides a filtering surface of a predetermined area using a plurality of water permeable blades 230, but since they are rotated in the direction of rotation of the filtering unit 200, even one blade Even when the life of the filtering surface of the filter 230 is exhausted first, the filtering surface of the rotated other blade 230 may contribute to the collection of microplastics, and as a result, the lifespan of the filter device 11 may be greatly increased.

Hereinafter, other embodiments of the present invention will be described. However, a description of the same or extremely similar configuration as the above-described embodiment will be omitted, which will be clearly understood by those skilled in the art from the accompanying drawings.

8 is a cross-sectional perspective view of a filter device according to another embodiment of the present invention. Fig. 9 is a cross-sectional side view of the filter device of Fig. 8; FIG. 10 is a schematic diagram showing one of the barbed fibers of FIG. 9 . 11 is a cross-sectional view of the barbed fiber of FIG. 10;

8 to 11, the filtering unit 202 of the filter device 12 according to the present embodiment is rotatably disposed in a plane to which the first direction (X) and the third direction (Z) belong, The filtering unit 202 includes a rotary shaft 210 and a water permeable blade 250, wherein the blade 250 includes a plate 251 and a plurality of barbed fibers 253 arranged on the plate 251. The point is different from the filter device and drainage system according to the embodiment of FIG. 2 and the like described above.

The plate 251 may have an arrangement substantially the same as or similar to the water-permeable blade of the above-described embodiment, for example, a mesh structure. That is, the plate 251 may be disposed to extend in the outer circumferential direction of the rotational shaft 210 on the rotational end surface of the filtering unit 202 . In addition, the plurality of plates 251 may be rotated around a rotation center. In addition, the plate 251 may extend in the second direction (Y) to form a predetermined area occupied by the plate 251 .

A passage hole 251h may be formed in the plate 251 so that a fluid flowing in a direction crossing an area occupied by the plate 251 , that is, a permeable surface may pass through the plate 251 . The passage holes 251h may be substantially arranged in a matrix on a plane provided by the plate 251, but the present invention is not limited thereto.

The passage hole 251h may not have a substantial filtering function for microplastics or microparticles. The passage hole 251h may impart water permeability to the blade 250 blocking the flow of fluid. For example, the size of the passage hole 251h may be 1 mm or more, or about 2 mm or more, or about 3 mm or more, or about 4 mm or more, or about 5 mm or more. The upper limit of the size of the passage hole 251h is not particularly limited, but may be, for example, about 20 mm or less, about 15 mm or less, or about 10 mm or less. With respect to the planar area provided by the plate 251, the area occupied by the plurality of flow holes 251h is about 1% to 50%, or about 2% to 45%, or about 3% to 40%, or about 4% to about 4%. 35%, or in the range of about 5% to 30%. If the size of the passage hole 251h is larger than the above range or the area occupied by the above range is larger than the above range, the area for sufficiently arranging the barbed fibers 253 to be described later may be insufficient. On the other hand, when the size of the passage hole 251h is smaller than the above range or the area occupied by the above range is smaller than the above range, it is not possible to provide a cross-sectional area of the passage sufficient for passing the fluid after microplastics are filtered, and the filtering unit 202 Rotation may increase.

The barbed fibers 253 may protrude from the plate 251 . The barbed fiber 253 may be a means for directly filtering microplastics included in the fluid flowing along the inside of the housing 100 . The barbed fiber 253 may be understood as a substantially linear structure extending in one direction for filtration of microplastics. 9, etc., when several barbed fibers 253 are arranged on one plate 251 for clarity of expression, specifically, three barbed fibers between two adjacent passage holes 251h in one direction ( 253) is arranged, but the present invention is not limited thereto. Any one blade 250 may include dozens of barbed fibers 253 or hundreds of barbed fibers 253 . Accordingly, the barbed fibers 253 adjacent to each other on one plate 251 may contact and intertwine with each other to form an air gap structure therebetween. Specifically, the branches 253b of the barbed fibers 253 may contact and intertwine with each other to form an air gap structure.

As described above, the plane provided by the plate 251 of the blade 250, specifically, the plate 251 located at 12 o'clock and 6 o'clock at any moment may substantially coincide with the fluid cross section. At this time, extension directions of the barbed fibers 253 of the blades 250 located at the 12 o'clock and 6 o'clock directions may be substantially parallel to the flow direction of the fluid flowing in the housing 100 .

Specifically, on the rotational cross section, the extension direction of the barbed fibers 253 may be substantially perpendicular to the extension direction of the plate 251 or may form an angle between them within about 30°. More specifically, when the plate 251 extends in a normal direction on the rotational end surface, the plurality of barbed fibers 253 extend in a substantially tangential direction on the rotational end surface, or form an angle between the tangential direction and the tangential direction within 30°. direction can be extended.

As will be described later, the barbed fiber 253 includes a plurality of protruding branches 253b, and microplastics in the fluid can be filtered using the branches 253b. Therefore, at the moment when the blade 250 is located at the position showing the maximum fluid resistance, that is, at the moment when the blade 250 is located at 12 o'clock and 6 o'clock, the barbed fiber 253 is parallel to the fluid flow direction to increase the filtration efficiency can be maximized. In other words, when the barbed fibers 253 are arranged in a direction exceeding 30° with respect to the tangential direction, the filtration efficiency may decrease.

In addition, the plurality of barbed fibers 253 may be disposed on only one side of the plate 251 between one side and the other side. However, the present invention is not limited thereto. For example, when the filtering unit 202 is configured to be rotated counterclockwise by the flow of fluid, the barbed fiber 253 may be disposed on a surface directly opposite to the flow of fluid. That is, the barbed fibers 253 may be disposed on the clockwise side of the circularly arranged plate 251 .

Hereinafter, the barbed fiber 253 will be described in detail.

Any one barbed fiber 253 may include a fiber body 253a (or fiber body) and a plurality of branches 253b protruding from the fiber body 253a. An extension direction of the fiber body 253a may coincide with an extension direction of the barbed fiber 253 .

The branch 253b may refer to a portion that protrudes or extends from the fiber body 253a. The extension direction of the branch 253b may intersect with the extension direction of the fiber body 253a. The branch 253b may be integrally formed without a physical boundary with the fiber body 253a.

As a non-limiting example, the barbed fiber 253 according to the present embodiment may be prepared by partially cutting a fibrous structure having a substantially uniform thickness in an oblique direction and spreading the cut portion. Branches 253b may be formed regularly or irregularly. Accordingly, the fiber body 253a may have a partially depressed portion 253c on the side surface. The size and shape of the depression 253c may roughly correspond to that of the adjacent branch 253b. That is, when the branch 253b is pressed, the branch 253b is inserted into the depression 253c and the shape of the first fibrous structure may be obtained. A width of the barbed fiber 253 in a portion where the depression 253c is formed may be smaller than a width in a portion where the recessed portion 253c is not formed. The maximum width (W) or maximum thickness of the fiber body 253a may be about 0.1 mm to 2 mm, or about 0.5 mm to 1.8 mm, or about 0.7 mm to 1.5 mm.

As described above, the branch 253b may be prepared by first cutting and spreading a fibrous structure having a uniform thickness. In an exemplary embodiment, the ratio (Wg/W) of the width (Wg) of the cut portion to the maximum width (W) of the fiber body 253a may be about 50% or less, or about 40% or less. In addition, the lower limit of the ratio (Wg/W) may be about 30% or more. Here, the width Wg of the cut portion may mean the width of the recessed portion 253c in the fiber thickness direction.

If the ratio (Wg/W) is too large, the width of the fiber body 253a becomes too small near the recessed portion 253c, and the barbed fiber 253 breaks near the recessed portion 253c, resulting in poor durability. may be lowered On the other hand, when the ratio (Wg/W) is smaller than the above range, it may be difficult to form the branch 253b having a sufficient length (L).

In addition, an angle between the extension direction of the branch 253b and the extension direction of the fiber body 253a, for example, an acute angle ( θ 1), may be a major factor influencing the efficiency of collecting microplastics during drainage. For example, an angle θ 1 formed between the branch 253b and the fiber body 253a may be an acute angle ranging from about 1 degree to less than 90 degrees, or about 10 degrees to 89 degrees. In a state where the barbed fiber 253 is fixed on the plate 251, the branch 253b may be inclined to form an acute angle toward a direction opposite to the flow direction of the fluid. That is, the branch 253b may be inclined in a direction away from the plate 251 . For example, the branch 253b of the barbed fiber 253 of the blade 250, which is located at the 6 o'clock direction at any moment and receives the maximum fluid flow resistance, is inclined to form an acute angle toward the fluid inlet 121h. It can be.

Preferably, the first angle θ 1 formed by the extension direction of the branch 253b and the fiber body 253a may be within a range of about 40 degrees to 60 degrees, or about 45 degrees to 55 degrees. Adjacent barbed fibers 253 may be entangled with each other or form a bundle to form air gaps for permeation of fluid and filtration of microplastics. If the angle θ 1 is too small, it may be difficult to effectively collect using the adjacent branch 253b. On the other hand, if the angle θ 1 is too large, the number of barbed fibers 253 arranged on one plate 251 may decrease and the collection efficiency may decrease.

On the cross-sectional view of the barbed fiber 253, the minimum angle θ 2 formed between the side surface of the fiber body 253a and the recessed portion 253c is the ratio (Wg/W) occupied by the width (Wg) of the cut portion, It may be appropriately selected or designed in consideration of the angle θ 1 toward which the extension direction of the branch 253b is directed, the length L of the branch, etc., but, for example, the side surface of the fiber body 253a and the depression 253c The minimum angle θ 2 formed by ) may be in the range of about 10 degrees to about 45 degrees. If the minimum angle θ 2 is too small, the thickness of the branch 253b may become too thin and the branch 253b may be detached from the fiber body 253a. In this case, the detached branches 253b may be drained, causing the microplastics to be drained. On the other hand, if the minimum angle θ 2 is too large, it may be difficult to form the branch 253b to a sufficient length L within the limited width Wg of the depression 253c.

In some embodiments, the extended length L of branch 253b may range from about 0.3 mm to 1.0 mm, or from about 0.4 mm to 0.8 mm, or from about 0.5 mm to 0.7 mm. If the length (L) of the branch (253b) is too large, the separation distance between adjacent barbed fibers (253) forming a bundle increases, resulting in an enlarged air gap due to mutual interference and a reduction in the filtration efficiency of the microplastics. . On the other hand, if the length (L) of the branch 253b is too small, the probability of microplastics getting caught in the branch 253b may decrease and the filtration efficiency of the microplastics may decrease.

The barbed fiber 253 may include a plastic material. Specifically, the barbed fiber 253 may be made of a material that has sufficient ductility and does not cause shape deformation even under high hydrothermal conditions. For example, the barbed fiber 253 has excellent flexibility and can withstand a temperature of about 100°C or higher, or about 120°C or higher, or about 140°C or higher, or about 150°C or higher, or about 160°C or higher, or about 180°C or higher. , or a plastic resin having a melting point of about 190° C. or higher, or about 200° C. or higher, such as polyethyleneterephthalate (PET) or polypropylene (PP). Preferably, the barbed fiber 253 may be made of a plastic resin material having a melting point of about 150° C. or higher.

Although the present invention is not limited thereto, polycarbonate (PC) resin may not be suitable for the implementation of the present embodiment due to its low flexibility. As another example, in the case of polyethylene (PE) resin having a melting point of less than 150° C., it is melted during a high-temperature drainage process, and the concentration of the plastic resin component increases during drainage, or at least the shape deformation of the barbed fiber 253 is caused. may not be suitable.

The water-permeable blade 250 according to the present embodiment is a bundle in which a plurality of barbed fibers 253 are arranged parallel to the fluid flow direction at the moment when the water permeable blade 250 is placed at the position of maximum resistance to the fluid flow, that is, the fluid cross-section position. It is possible to collect the fine plastic fibers in the fluid using the branch 253b extending obliquely in the opposite direction to the flow of the fluid. In other words, with respect to the fluid flowing in the first direction (X), each barbed fiber 253 extends in the first direction (X), and the plurality of barbed fibers 253 are second perpendicular to the fluid flow direction. A permeable surface or a filtering surface may be formed by forming a bundle in a plane to which the direction Y and the third direction Z belong.

In particular, the barbed fibers 253 are arranged in parallel with the fluid flow direction, and a plurality of branches 253b are arranged in the extending direction of the barbed fibers 253, that is, in the extending direction of the fiber body 253a. Therefore, the barbed fibers 253 forming a bundle have the same effect as when about 10 or more, 20 or more, or 30 or more conventional mesh filters are disposed along the first direction X, which is the direction of extension. can indicate

12 is a cross-sectional side view of a filter device according to another embodiment of the present invention.

Referring to FIG. 12, the filtering unit 203 of the filter device 13 according to the present embodiment is rotatably disposed in a plane to which the first direction X and the third direction Z belong, and the filtering unit ( 203) includes a rotating shaft portion 210 and a water permeable blade 250, wherein the blade 250 includes a plate 251 and a plurality of first barbed fibers 253 arranged on one side of the plate 251 and a plurality of second barbed fibers 255 arranged on the other side of the plate 251, which is different from the filter device and drainage system according to the embodiment of FIG. 8 described above.

For example, when the filtering unit 203 is configured to rotate counterclockwise by the flow of fluid, the first barbed fiber 253 will be disposed on the surface of the plate 251 directly opposite to the flow of fluid. can That is, the first barbed fibers 253 may be disposed on the clockwise side of the circularly arranged plate 251 .

In addition, the second barbed fibers 255 may be disposed on the other side of the plate 251 facing the fluid flow. That is, the second barbed fibers 255 may be disposed on the counterclockwise side of the circularly arranged plate 251 .

As described above, the first barbed fibers 253 are inclined so that branches form an acute angle in a direction opposite to the flow direction of the fluid. In an exemplary embodiment, the branches of the second barbed fibers 255 may be arranged to form an acute angle in the same direction as the branches of the first barbed fibers 253 . For example, both the branch of the first barbed fiber 253 and the branch of the second barbed fiber 255 of the blade 250 located at the 6 o'clock direction and receiving the maximum fluid flow resistance are fluid inlets. It may be inclined to form an acute angle toward (121h).

In the filter device 13 according to the present embodiment, the fluid before passing through the passage hole 251h of the plate 251 collects microplastics using the first barbed fiber 253 and passes through the passage hole 251h. After passing through the fluid, microplastics can be additionally collected using the second barbed fiber 255, thereby improving microplastic filtration efficiency.

However, the present invention is not limited thereto, and in another embodiment, the branches of the second barbed fibers may be inclined in the opposite direction to the branches of the first barbed fibers 253 .

13 is a cross-sectional side view of a filter device according to another embodiment of the present invention.

Referring to FIG. 13, the filtering unit 204 of the filter device 14 according to the present embodiment is rotatably disposed in a plane to which the first direction X and the third direction Z belong, and the filtering unit ( 204), the water permeable blade 230 is not completely disposed on the surface of the rotating shaft 210 in the direction normal to the surface of the rotating shaft 210, but is disposed inclined so as to intersect the normal direction at a predetermined angle. It is different from the filter device and drainage system according to.

13 illustrates a case where the water-permeable blade 230 is formed by including a mesh structure as described above with reference to FIG. Of course, it may be formed including.

In an exemplary embodiment, the blade 230 may be arranged to form an inclination angle of about 3° to 15°, or about 5° to 10° with the normal direction of the rotating shaft 210 on the rotating cross section. When the angle at which the blades 230 are inclined is greater than the above range, the efficiency of collecting microplastics may decrease because the blades 230 do not receive sufficient fluid resistance.

As described above, the filtering unit 204 may be configured to be rotatable by the fluid flowing along the inside of the housing 100 . At this time, forming a consistent rotational direction of the filtering unit 204 may be an important factor in terms of separation or prevention of separation of the microplastics collected by the blades 230 . At this time, in the flow resistance of the fluid that affects the rotation direction of the filtering unit 204, the blade 230 located on one side, for example, at 6 o'clock, has a higher fluid flow than the blade 230 located on the other side, for example, at 12 o'clock. By configuring to receive a large resistance, fluid flow in the corresponding direction becomes dominant, and the rotation direction of the filtering unit 204 can be controlled using this.

14 is a perspective view of a filter device according to another embodiment of the present invention. Fig. 15 is a cross-sectional perspective view of the filter device of Fig. 14; Fig. 16 is a cross-sectional side view of the filter device of Fig. 14;

14 to 16, the filtering unit 200 of the filter device 15 according to the present embodiment is rotatably disposed in a plane to which the first direction X and the third direction Z belong, The housing 105 is different from the filter device and the drainage system according to the embodiment of FIG. 2 and the like in that the housing 105 partially includes parts having different widths.

14 and the like illustrate a case where the water-permeable blade 230 is formed by including a mesh structure as described above in FIG. Of course, it may be formed including.

In an exemplary embodiment, the housing 105, specifically, the housing body 115 includes a first housing portion 115a having a relatively small width (eg, a passage space width and an inner width) in the third direction Z, and A second housing portion 115b having a relatively large width in the third direction Z may be included. 14 and the like illustrate a case where one second housing part 115b is positioned between two first housing parts 115a spaced apart from each other in the first direction X.

In this case, the maximum width of the filtering unit 200 in the third direction Z may be greater than the width of the first housing part 115a and smaller than or equal to the width of the second housing part 115b. The filtering unit 200 may be disposed within the second housing portion 115b. Specifically, the rotary shaft part 210 of the filtering unit 200 may be disposed within the second housing part 115b.

In addition, among the plurality of blades 230 disposed in the radial direction to surround the rotating shaft portion 210, at least some of them overlap the first housing portion 115a (or its internal space) in the first direction X, or It is positioned overlapping, and at least a portion may be arranged so as not to overlap with the first housing part 115a (or its inner space) in the first direction (X). Accordingly, the fluid flowing from the fluid inlet port 121h along the fluid outlet port 122h forms a permeable surface (or filtering surface) formed by the blade 230 overlapping the first housing part 115a in the first direction X. The blade 230 passing through the bay and not overlapping with the first housing part 115a may not substantially affect the flow of the fluid. Through this, the filtering unit 200 may be induced to rotate only in a counterclockwise direction (refer to FIG. 16 ) by the fluid flowing along the inside of the housing 105 .

In addition, when the volume of the inner space of the housing 105 is excessively large, a bottleneck phenomenon may occur in the flow of fluid passing through the filter device 15 and flowing into the second conduit unit. Therefore, there is an effect that the passage volume provided by the housing 105 can be configured to be relatively small.

Hereinafter, a case in which the processor 910 includes a collection unit 911, a determination unit 912, and an alarm unit 913 as functional components performed by the processor 910 will be described as an example, but the present invention is limited thereto. Of course, it is not interpreted.

In the method for providing a replacement alarm for a filter device according to an embodiment of the present invention, information on a rotation amount of a filtering unit of a filter device 11 is provided (S100), the collected rotation amount is compared with a reference value (S200), It may include providing an alarm according to the comparison result (S300).

The collection unit 911 may collect information about the rotational amount of the filtering unit of the filter device 11, such as rotational speed, rotational direction, and cumulative rotational number (S100). The collection is performed by the sensor unit of the filter device 11 and transmitted and received through the communication unit as described above.

The determining unit 912 may compare the collected information on the amount of rotation of the filtering unit with a reference value (S200).

For example, the rotational speed of the filtering unit may be compared with a reference value. As a result of the comparison, when the rotational speed of the filtering unit exceeds or exceeds a predetermined standard, that is, when it is recognized to rotate at a relatively high speed, it may be determined that the lifespan of the filter device 11 is somewhat exhausted. On the other hand, when the rotational speed of the filtering unit is less than or less than a predetermined standard, that is, when it is recognized to rotate at a relatively slow speed, it may be determined that the life of the filter device 11 remains.

For another example, the cumulative number of revolutions of the filtering unit may be compared with a reference value. As a result of the comparison, when the cumulative number of rotations of the filtering unit exceeds or exceeds a predetermined standard, it may be determined that the life of the filter device 11 is somewhat exhausted. On the other hand, when the cumulative number of revolutions of the filtering unit is less than or less than a predetermined standard, it may be determined that the life of the filter device 11 remains.

According to the present invention, the life of the filter device 11 can be measured or estimated based on the rotational speed of the filtering unit without a complicated configuration such as deriving differential pressure by measuring pressure at a plurality of locations in the flow path as in the prior art. .

As a result of the determination, when it is determined that the speed of the filtering unit is high or the accumulated number of revolutions is high, the alarm unit 913 indicates that the life of the filter device 11 has been exhausted and that all or part of the filter device 11 needs to be replaced or repaired. It is possible to generate alarm information about the presence of (S300). On the other hand, as a result of the determination, when it is determined that the speed of the filtering unit is low or the accumulated number of rotations is low, the collection unit 911 may continuously monitor information about the rotational speed of the filtering unit.

That is, components related to the above-described collection unit 911, determination unit 912, and alarm unit 913 should be interpreted as a computing device constituting either the server 2 or the user terminal 3.

In another embodiment, the replacement alarm system of the filter device may omit the user terminal 3 . In this case, it can be understood that all or some of the components of the server 2 described above are included in the filter device 11. That is, components related to the above-described collection unit 911, determination unit 912, and alarm unit 913 are computing devices constituting any one of the server 2, the user terminal 3, and the filter device 11. should be interpreted Also, the alarm generated by the alarm unit 913 may be implemented through a speaker of the filter device 11 and/or a light emitting unit such as an LED.
