Hereinafter, the present invention will be described with reference to the accompanying drawings. In describing the present invention, when it is determined that the detailed description of the related well-known technology or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. will be.

The following terms are terms defined in consideration of functions in the present invention and may vary according to intentions or customs of users or operators, and the definitions thereof should be understood based on the contents throughout the specification for describing the present invention. .

1 is a side structural view of the zigzag fiber filtration filter in accordance with an embodiment of the present invention, Figure 2 is a side structure of the compression release side of Figure 1, Figure 3 is a basic structure of the zigzag fiber filtration filter of Figure 1 to be.

In the prior art, the fibrous media formed mainly in bundles is used to be densely arranged in a cylindrical shape or arranged in a planar shape, and there is an advantage in that the formation of the filter pores and the backwashing pores can be relatively freely formed by the method of crimping or crimping. .

However, in the prior art, a strainer serving as a crimping support is used as an essential component in order to form filtration pores of the fibrous media. Such a prior art method can be easily operated in a small strainer type, but the length of the fibrous media In the large strainer that needs to be long, the tension of the filtrate does not reach the center part, so the splitting occurs in the middle part of the fibrous media due to water pressure and agglomeration by suspended solids. There is a problem, and the area of the filtration layer is determined by the size of the strainer serving as a support.

In order to solve this problem, the present embodiment does not damage the filtration layer regardless of the area of the fibrous media, and provides an apparatus having a structure capable of adjusting the filtration area and further eliminating the strainer.

As shown in FIG. 1 and FIG. 2, the zigzag-type fiber filtration filter includes a plurality of support rods 210 fixed in parallel to one side surface of the fibrous media 10 of the planar layer and the fibrous media 10, and A plurality of pressing rods 200 parallel to the supporting rod 210 on the other side of the fibrous media 10 and arranged to cross the supporting rod 210, and the pressing rod 200 to the fibrous media 10 It may be composed of a fiber media air gap controller 20 to be pushed in or pulled out).

As a result, as shown in FIG. 1, when the fibrous mediator pore controller 20 pushes the pressing rod 200 toward the fibrous mediator 10, the fibrous mediator 10 may be compressed while changing the fibrous mediator 10 in a zigzag form. , When the fiber media air gap controller 20 pulls the crimping rod 200 to the opposite side of the fiber media 10, the fiber media 10 is changed to a state in which it is not tense.

The fiber filter 10 is formed in a bundle of fiber yarns, it is widely used as a filter medium. The filtrate is used as a filter medium in the filtration process to form a filtration membrane, thus becoming a boundary between raw water and filtered water.

The fiber media air gap controller 20 is composed of a pressing rod connecting bar 202 for connecting and coupling each pressing rod, and an external actuator 203 acting on the pressing rod connecting bar 202, the pressing rod connecting bar 202 is connected to the crimping rod 200 by the support 201, the bridge 201 so that the crimping rod 200 protrudes from the crimping rod connecting bar 202 of the fibrous material 10 Pressing bar connecting bar 202 when the compression does not interfere.

That is, in the present embodiment, the zigzag compression of the fibrous media 10 is a control means for correcting the length of the fibrous media to form the filtration pores.

In detail, as shown in FIG. 2, before the crimping of the crimping rod 200, the long fibrous media 10 is loosely formed to form backwash voids, and as shown in FIG. 1, the fibrous media 10 after compression. Is tightened to form filtration pores.

The filtration capacity formed by the fibrous media 10 is determined by the area of the filtration layer formed by the fibrous media 10 during compression. According to the present invention, the fibrous media 10 has tension due to zigzag compression. While forming the filtration pores, the area of the filtration membrane formed by the fibrous media 10 becomes the same area as the zigzag length.

That is, as shown in FIG. 3, the area of the fibrous media zigzag ten times with the length of the unit a in the longitudinal side direction is 10ab when the length of the transverse is assumed to be b.

Therefore, according to the present embodiment, there is an advantage that all the filter areas corresponding to the original length of the fibrous media 10 can be utilized, and the compression movement distance of the crimping rod 200 and the length of the fibrous media 10 are adjusted. By having a feature that can be adjusted in a variety of areas.

On the other hand, the present embodiment is to compensate for the length by pressing the fibrous media 10 with the pressing rod 200, as shown in Figure 1, if the distance (compression distance) is long, the margin length of the fibrous media 10 is long, the prior art As in the manner of the support rod 210 instead of the structure having a strainer is not possible because it interferes with the crimping path.

Therefore, in this embodiment, the strainer is omitted and replaced with a support rod to form a boundary between the filtrate and the raw water only with the fibrous media 10, which leads to a reduction in the apparatus cost.

Even if the strainer is omitted as in the present invention, there is no effect on the filtration performance if there is no damage to the fibrous media forming the filtration membrane.

In addition, by removing the strainer as described above, the length of the fibrous media 10 can be freely selected, so that the cross-sectional length of the filtration membrane formed by the zigzag can be kept long (the actual filtration membrane becomes wider). As shown in the figure, the backwashing space R can be secured at the time of backwashing of the fibrous media 10 so that the filtration and backwashing efficiency are greatly increased.

4 is a diagram illustrating a first use of a zigzag fiber filtration filter according to the present invention.

In the present invention, as shown in FIG. 4, raw water may be input from the upper side to filter the fibrous media 10, and a basic filter may be configured to discharge the filtered water to the lower side. Can be used to make more efficient use.

5 is a perspective view of a frame-shaped grid frame for symmetrically configuring the fibrous material used in the second use example according to the present invention, and FIG. 6 is an exemplary perspective view of the second use example according to the present invention.

As shown in FIG. 5, the zigzag fiber filtration filter has a fibrous filter 10 as shown in FIG. 6 at the top and bottom of the frame-like lattice frame 30 in which a plurality of support rods 210 are formed at equal intervals in the horizontal direction. Roll) to form a filtration layer on both sides of the frame grid, the pressing rod 200 is formed by connecting with the fibrous media gap controller 20 on both sides of the fibrous media (10).

The fibrous media air gap controller 20 is formed so that the pressing rod 200 enters or exits between the supporting rods 210 of the frame-type lattice frame 30, as shown in FIG. 6, and one side of the frame-type lattice frame 30. The vertical frame forms a drain hole 301 so that the inside communicates with the outside.

According to such a structure, both surfaces of the framed grid frame 30 are formed with a filtration membrane by the fibrous media 10, and the interior and exterior of the framed grid frame 30 has a space having the fibrous median filtration membrane as a filtration boundary. do.

That is, when the raw water to be filtered is filled outside the framed grid frame 30, the raw water is filtered through the filtration membrane and introduced into the framed grid frame 30, and the introduced filtered water is formed on the side of the framed grid frame 30. It is discharged to the outside through the formed drain hole (301).

Such a symmetrical zigzag fiber filtration filter can increase the filtering capacity by placing a plurality of parallel to the filtration chamber 100 into which the raw water flows.

According to the above configuration, during the filtration, the fibrous median air gap controller 20 allows the pressing rod 200 to enter the framed grid frame 30 between the supporting rods 210 so that the fibrous media 10 is zigzag. By pressing, it is possible to form filtration pores having a large filtration area.

At this time, the raw water passes through the fibrous media 10 from the outside of the frame-type grid frame 30 and moves to the inside of the frame-type grid frame 30 and forms a filtration path discharged to the outside through the drain hole 301. Let's do it.

In addition, during backwashing, the fiber media air gap controller 20 allows the crimping rod 200 to emerge from the inside of the frame-like grid frame 30 so that the fiber media 10 is released from compression, as shown in FIG. 2. Make sure you have enough room to loosen it.

At this time, the backwash water flows through the drain hole 301 formed on the side of the frame-type grid frame 30, passes through the fibrous media 10, and forms a backwash path to flow outward of the frame-type grid frame 30. Let's do it.

During backwashing, the fiber media 10 is rinsed off by washing with backwash water by air supplied from the air spray pipe 330 provided on the bottom surface, and in this embodiment, the fiber media 10 may be shaken during backwashing. Since enough space is secured, it proceeds as if the fiber media 10 is washed with air bubbles.

Hereinafter, an embodiment in which the filter of the present invention is actually immersed in the filtration chamber 100 will be described.

Is a side cross-sectional structural view of the decompression, and FIG. 12 is a practical use coupling diagram of the filtration device of the third use example of the present invention.

A third use example of the present invention is a filtration device using one symmetrical zigzag fiber filtration filter.

The filtration device using the zigzag fiber filtration filter is composed of a filtration chamber 100, a raw water inlet pipe 120, a backwash water discharge pipe 110, a zigzag fiber filtration filter and an air spray pipe (330).

As shown in Figure 9, the filtration chamber 100 means a storage tank for storing the incoming raw water.

Therefore, the filtration chamber 100 is formed with a pipe communicating with the outside, the raw water inlet pipe 120 is formed in communication with one side of the filtration chamber 100, as shown in Figure 12 to the external raw water to be filtered It is an inflow tube. Of course, according to an embodiment, the raw water inlet pipe 120 may be formed of a simple hole or a connecting pipe.

The backwash water discharge pipe 110 is a tubular body formed in communication with the filtration chamber 100 at the height of the desired water level during backwashing.

The zigzag fiber filtration filter is placed in the filtration chamber 100, and the filtration water discharge pipe 130 is connected to the drain through hole 301 of the zigzag fiber filtration filter to communicate with the outside to discharge the filtered water.

By such a structure, a filtration chamber structure is completed in which raw water is indented to the outside and filtrate is filled in the interior of the zigzag fiber filtration filter.

The raw water inlet pipe 120 and the backwash water discharge pipe 110 are respectively opened at the time of filtration and backwash by control valves, and the raw water introduced through the raw water inlet pipe 120 is filtered to the filtered water discharge pipe 130. Since it is discharged, the height of the filtered water discharge pipe 130 determines the level of the incoming raw water at the beginning of the filtration.

As the filtration progresses and the filtration performance of the fibrous media 10 decreases, the level of raw water is gradually increased. Such a level of raw water is the basis for determining the filtration performance of the fibrous media 10.

Accordingly, a level gauge is provided inside the filtration chamber 100 to form a control device such that backwashing proceeds when the raw water reaches a predetermined level or more.

When backwashing proceeds, the raw water inlet pipe 120 is closed and the backwash water discharge pipe 110 is opened, and a separate reverse station is provided to communicate with the drain water hole 301 as shown in FIG. 12. The backwash water is introduced through the washing water inlet pipe 140.

Therefore, the water level of the inlet backwash water is determined by the height of the backwash water discharge pipe 110, so that the height of the backwash water discharge pipe 110 is preferably set to a height at which sufficient backwash space is secured.

The air injection pipe 330 is a pipe body formed parallel to the bottom of the zigzag fiber filtration filter inside the filtration chamber 100, and a plurality of through holes facing the fiber filter are formed, as shown in FIG. 12. It is connected to the external air blower 500 through the air injection pipe 150.

In the case of the filtration chamber 100 as in the embodiment of the present invention, since the zigzag fiber filtration filter has a flat plate shape, the shape of the filtration chamber may also be formed relatively thin in a plate shape to form a small installation space.

The most problematic for this purpose is the fiber filter pore controller 20 of the zigzag fiber filtration filter. In the present invention, the fiber filter pore controller 20 is configured to occupy the smallest space in the filtration chamber 100. Suggest that.

Hereinafter, the fiber media air gap controller 20 will be described.

In the embodiment of the present invention, the fiber media air gap controller 20 includes a guide plate 205, a crimping rod connecting bar 202 as shown in FIG. 8, and an external actuator 203. It is configured as shown in Figure 9 to compress the fibrous media formed as shown.

The guide plate 205 is a plate that is fixed to both sides of the frame type grid frame 30 of the zigzag filtration filter as shown in Figures 10 and 11, the guide plate 205 is a symmetrically tapered compression bar sliding guide Holes 205-1 (which function as cam holes) are formed at equal intervals in the vertical direction.

In the compression bar sliding guide hole 205-1 (cam hole), as shown in the enlarged circle of FIG. 10, the compression bar 200 (functioning as a cam) is slidably coupled (cam coupling).

The pressing rod connecting bar 202 is a vertical bar connecting the centers of the pressing rods 200 as shown in FIG. 8, and the pressing rod connecting bar 202 is connected to an external actuator 203 for driving up and down. Connect.

In order to allow the pressing rod 200 to protrude from the pressing rod connecting bar 202 also to the pressing rod connecting bar 202 so that the pressing rod connecting bar 202 does not interfere when the fiber media 10 is pressed. The bridge 201 shown in FIG. 1 and FIG. 2 is formed.

The external actuator 203 is a piston or a corresponding device for generating a vertical reciprocating motion.

As shown in FIGS. 10 and 11, when the pressing rod connecting bar 202 is lifted by the external actuator 203, the pressing rod 200 in the guide plate 205 is driven to slide (cam motion). Since the fiber media is moved in the front and rear directions, the pores of the fiber media 10 are controlled by pressing or releasing the fiber media 10.

On the other hand, the frame-type grid frame 30 is the same as the upper frame 320 and the lower frame 330: the lower frame (330: air frame) is wound around the fibrous media 10, as shown in Figure 10 and 11 To form a rhombus rectangular cross section to prevent slipping, and the fiber filter portion wound on the upper frame 320 and the lower frame 330 has an L-shaped cross-section of the long fiber filter cover (upper fiber filter cover ( 321), the lower fibrous media cover 331) to fix the fibrous media (10).

In addition, the air injection pipe 330 is an internal air injection through the inner side of the fibrous media 10 at equal intervals on the two upper surfaces of the lower frame 330 of the frame-like grid frame 30 as shown in FIG. It is formed by the air injection pipe (330-1) formed.

In addition, the frame-type lattice frame is installed in parallel to both sides of the lower frame and is configured to further include an external air injection pipe 340 is formed with an external air injection through holes facing the outside of the fibrous media 10 at equal intervals.

That is, by forming the lower frame 330 of the frame-shaped grid frame 30 to which the fibrous media 10 is wound with an air spray tube and forming an internal air spray through hole 330-1 at equal intervals, the fiber media The backwashing air was also injected into the inside of the 10, and two external air injecting pipes 340 were formed to be symmetric about the lower frame 330 of the frame-like grid frame 30 to the outside of the fibrous media 10. Edo air is to be injected, so that the fibrous media 10 is sufficiently backwashed by the air injected from the inside and outside.

In this use example, in order to have directivity of the air injected from the bottom frame 330 of the frame-like grid frame 30 toward the fiber media 10, the lower frame 330 is an element introduced for fixing the fiber media Inner air injection holes are formed on both top surfaces of the rhombus, and the air injected by the inclination angle of the rhombus has directivity toward the fiber media.

Hereinafter, a fourth use example of the present invention will be described.

Referring to FIG. 13, the filtration chamber 100 is a space where substantial filtration and reciprocal water are generated, and the raw water inflow chamber 400 is filtered as a storage space communicated by the filtration chamber 100 and the communication port 410. It is a space to store raw water primarily.

As shown in FIG. 16, the raw water inflow chamber 400 forms a double layer structure with the backwash water channel 40. The lower layer forms the raw water inflow chamber 400 and the upper layer forms the backwash water channel 40. That is, the backwash channel 40 is formed at the upper end of the raw water inlet chamber 400 and is a space separated by the filtration chamber 100 and the partition wall 420.

A plurality of fiber filtration filters are provided in the filtration chamber 100.

The fiber filtration filter forms a filtration layer by rolling up the fiber filter 10 outside the frame-like lattice frame 30 to form a filter layer, and a means for blowing back air into the fiber filter 10 is provided.

Framed grid frame 30, the one-side frame 31 and the lower frame 330 formed in an L-shape formed as a hollow tube is used as the inflow space of the back-air, the upper frame 350 and the other frame formed in the L shape 32 is formed as a support frame, the support rod 210 is formed horizontally at equal intervals in the one side frame 31 and the other side frame 32.

The support rod 210, the upper frame 350 and the lower frame 330 outside the fibrous media 10 as shown in Figure 15 to be arranged in a dense arrangement to form a filtration layer.

As shown in FIG. 14, the inlet space of the backwash air forms an internal air injection through hole 330-1 at equal intervals above the lower frame 330, which enters the inside of the fibrous media 10, and the one side frame 31. The upper side is connected to the external air blower 500 to form a backwash air injection path.

In this use example, a plurality of such fiber filtration filters are arranged horizontally in the filtration chamber 100 as shown in FIG. 13.

The treated water chamber 600 forms a drain hole 301 in the other frame 32 of the fiber filtration filter as shown in FIG. 14, and communicates with the inside of the fiber filtration filter through the drain hole. As described above, the space is connected to the external treated water tank 620 through the drain pipe 630 controlled by the treated water discharge control valve 610.

That is, the treated water chamber 600 is a space for communicating the inside of the fiber filtration filter and the external treated water tank 620.

An inflow pipe 430 through which raw water flows in common is connected to the treated water chamber 600 and the raw water inflow chamber 400, and the inflow pipe 430 is the raw water inflow chamber 400. Water is selectively introduced into the treated water chamber 600 by the control of the control valve 440.

Filtration pores of the fibrous filter 10 of the filtrate filter are controlled by the fibrous filter pore controller 20.

As shown in FIGS. 18 and 20, the fibrous mediating air gap controller 20 includes an external actuator, a lifting bar 500, a hinge pin 510, a pressing rod 200, and a lever pin 512.

The elevating bar 500 is attached to both sides between the fiber filtration filter on the inner wall of the filtration chamber 100 and is a device for vertical lifting by receiving the movement of the external actuator (not shown).

As shown in FIG. 20, the hinge pin 510 of the present invention is symmetrically formed at equal intervals in the vertical direction on both sides of the elevating bar 500, and is coupled to the elevating bar 500 by a hinge 511.

A straight sliding slot 514 is formed at the center of the hinge pin 510, and a lever pin 512 fixed to an inner wall of the filtration chamber 100 is formed at the straight sliding slot 514. Penetrates.

Therefore, the lifting motion of the lifting bar 500 is to move the hinge pin 510 by the hinge 511, around the lever pin 512, the linear sliding slot 514 is The length difference between the hinge 511 and the lever pin 512 is corrected for the rotational motion by the hinge 511.

Compression rod 200 is a rod coupled to the end of the hinge pin 510 formed on the both lifting bar 500 as shown in Figure 20, in a direction crossing the fiber filtration filter as shown in FIG. Is formed.

Therefore, the vertical movement of the elevating bar 500 by the external actuator (not shown) is transferred to the lever movement centering on the lever pin 512, and the fibrous media positioned on the side surface by the pressing rod 200 ( By pressing 10 as shown in FIG. 16 or by releasing the press as shown in FIG. 17, the voids of the fibrous material 10 are controlled.

On the other hand, since the pressing rod 200 and the support rod 210 is a rod formed in the same direction, the support rod 210 performs the function of the pressing support when the pressing rod 200 is pressed.

In this example, filtration and backwashing are performed by controlling the control valve 440 of the inlet pipe 430 and the control valve 610 for discharging the treated water.

During filtration, raw water is introduced into the raw water inlet chamber 400 by controlling the control valve 440 of the inlet pipe 430, and the fiber filter 10 is compressed by the fiber filter pore controller 20 to filter the fiber filter. A filtration cavity is formed in the filter chamber, and the filtration path is formed by connecting the treated water chamber 600 with the external treated water tank 620 by the control valve 610 for discharging the treated water.

According to the filtration path, the inlet pipe 430 introduces raw water into the raw water inlet chamber 400, and moves the raw water to the filtration chamber 100 through the communication port 410 in the raw water inlet chamber 400.
