Description

Zigzag type fiber filtration device {ZIGZAG TYPE FIBER FILTER APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber filtration apparatus, and more particularly, to a zigzag fiber filtration apparatus in which a fiber filter is compressed and relaxed in a zigzag fashion and a zigzag shape is changed.

In general, filters have been developed to efficiently improve filtration and backwashing while automating the filtration process for filtering raw water and the backwashing process for backwashing internal filters.

On the other hand, in terms of the capability of the filter, there are very strict divisions between the fields requiring precise fine filtration and the fields requiring the filtration of large suspended solids. In the fields requiring the primary filtration of relatively large suspended substances, the filtration capacity is required. The emphasis is more on the efficiency of filtration and backwashing.

In addition, the field of filter technology still requires efficient and smooth conversion of the filtration process and backwashing process, and there is a continuous need for technology that can reduce the manufacturing cost without any trouble even if the process conversion is performed periodically and continuously. It is done.

In addition, there is a continuous need to provide a device capable of automating pore control of the fibrous media forming the filter layer for the automated process of the filter.

On the other hand, the present inventors domestic patent registration Nos. 944229 and 967189 are designed to control the filtrate and the cleaning pores of the filtrate by allowing the filtrate to be compressed in a zigzag type or vice versa.

The prior art adjusts the filtration pores and cleaning pores of the fibrous media by pushing or squeezing the squeezing rods to the supporting rods.

This method has a problem in that the structure of the filtration device is relatively complicated because the driving direction of the actuator and the moving direction of the pressing rod cross each other in the orthogonal direction.

Meanwhile, as another conventional technology, Korean Patent Registration No. 995500 controls the air gap of the fiber material by zipping the fiber material on the horizontal rod of the fiber support and pulling or releasing the free end of the fiber material with an actuator. However, this technique has a problem in that the voids of the fibrous media are controlled in the region adjacent to the actuator, but the voids of the fibrous media are not controlled in the region far from the actuator due to the frictional force such as the horizontal bar.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention in the drawings, portions not related to the description are omitted, and like reference numerals are given to similar portions throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

First, the technical concept of the present invention will be described first.

1 and 2 are conceptual diagrams for explaining the technical concept of the present invention, Figure 1 is a state in which the fibrous media is relaxed, Figure 2 is a state in which the fibrous media is compressed.

As shown in Figure 1, the fibrous media 10, the support rod 130, the pressing rod 330, the fibrous media gap controller is disposed.

The fibrous media 10 forms a filtration surface (vertical surface in FIG. 1, etc.) arranged in the first direction by the fiber yarn, and is arranged in a zigzag manner along the first direction.

In addition, the upper end of the fibrous media 10 is fixed by the upper media fixing means, the lower end of the fibrous media 10 is fixed by the lower media fixing means.

The zigzag shape of the fibrous media 10 is made by the support rod 130 and the pressing rod 330.

Support rod 130 is disposed in a second direction orthogonal to the first direction on one side of the fibrous media 10, and the support rods 130 are provided in plurality in the first direction, but are provided in parallel with each other.

The support rod 130 is fixed to the chamber or frame.

On the other hand, the pressing rod 330 is disposed parallel to the support rod 130 on the other side of the fibrous media, but staggered with the support rod 130.

In order to move the pressing rod 330 as described above in the first direction, that is, the direction in which the fiber media 10 is disposed, a fiber media air gap controller is provided.

The fiber media air gap controller of the present embodiment includes an actuator 310, a lifting bar 320, a pressing rod 330, an auxiliary bar 340, and the like.

In the present embodiment, it is assumed that the first direction is a vertical direction, and it is assumed that the second direction is a horizontal direction.

The lifting bar 320 has an upper end thereof connected to the actuator 310 and vertically moving up and down by driving the actuator 310.

In addition, an auxiliary rod 340 is provided between the lifting bar 320 and the pressing rod 330 to transfer the vertical lifting movement of the lifting bar 320 to the vertical lifting movement of the pressing rod 330.

As described above, since the driving direction of the crimping rod 330 and the driving direction of the actuator 310 are the same, the structure thereof becomes very simple.

1 and 2 when the pressing rod 330 is moved to the intermediate position between the pair of support rods 130, the fibrous media 10 is relaxed, the pressing rod 330 between the pair of support rods 130 When moving in the opposite direction of the middle portion (direction away from the middle portion between the pair of support rods) it can be seen that the fibrous media 10 is pressed.

That is, when the elevating bar 320, the auxiliary rod 340, the pressing rod 330 moves downward by the actuator 310, the fibrous media 10 is relaxed, and the elevating bar is driven by the actuator 310. 320, the auxiliary rod 340, the pressing rod 330 is moved to the top, the fibrous media 10 is pressed.

This compression and relaxation process will be described in more detail with reference to FIGS. 3 and 4.

3 and 4 illustrate the minimum length of the fibrous material 10 according to the position of the pressing rod 320 between the pair of support rods 130.

In FIG. 3, the pressing rods 330 are disposed at an intermediate portion between the pair of supporting rods 130 disposed adjacent to each other, and the pressing rods 330 are pressed between the pair of supporting rods 130 disposed adjacent to each other in FIG. 4. The rod 330 is moved to the height of any one of the supporting rods 130.

For the convenience of calculation, it is assumed that the distance between the supporting rod and the supporting rod is 2, and the horizontal distance between the pressing rod and the supporting rod is 1.

In the case of Figure 3 when the fibrous media is pulled tightly between the support rod 130 and the pressing rod 330 is a straight length of the fiber media is 1.4 + 1.4 = 2.8.

However, in the case of Figure 4 when the fibrous media is pulled tightly between the support rod 130 and the pressing rod 330 is a straight length of the fiber media is 1.0 + 2.2 = 3.2.

Therefore, in order to compress the fibrous media in the state of FIG. 4, the length of the fibrous media should be 3.2 or less, and if the length of the fibrous media is 3.2 in the state of FIG. 4 and changed to the state of FIG. 3, the fibrous media is It has a margin that is loosened by 3.2-2.8 = 0.4 (0.4 / 3.2 x 10 = 12%).

According to the present invention, when the pressing rod is moved toward the middle between a pair of supporting rods disposed adjacent to each other, the fibrous media is relaxed, and the intermediate portion between the pair of supporting rods disposed adjacent to each other. Moving in the opposite direction (ie, away from the middle between the pair of supporting rods) was adapted to control the crimping and loosening of the fibrous media based on the compression of the fibrous media.

In addition, when the state of FIG. 4 is changed to the state of FIG. 3, the pressing rod 330 applies a mechanical force to change the shape of the fibrous media 10. Fiber media 10 in the state in which the fiber yarns are agglomerated with each other in the compressed state can be more easily relaxed and have the effect that the fiber yarns are separated from each other.

Normally, the fiber filter 10 is shaken by air when the fiber filter 10 is relaxed. If the fiber yarns are strongly agglomerated together, the fiber yarns of the fiber filter 10 may not be separated from each other by the force of air alone. In the present embodiment, while washing the fibrous media by the force of the air and at the same time the pressing rod 330 forcibly deforms the shape of the fibrous media 10 while the fiber yarns can be easily separated from each other in that the washing of the fibrous media The effect is very excellent.

Meanwhile, FIGS. 1 and 2 illustrate a state in which both ends of the fibrous media are fixed, but as shown in FIG. 5, one end of the fibrous media is fixed while the other end of the fibrous media is implemented to move together as the vertical bar moves up and down. More preferred.

FIG. 5 is a view corresponding to FIG. 2, which illustrates a case where one end of the fibrous material moves together with the lifting bar.

In Figure 5, the lifting bar 320 is provided with a moving plate 350 for fixing the fibrous material.

In addition, the lower end of the fibrous media 10 is fixed by the lower media fixing means, while the upper end of the fibrous media 10 is fixed to the moving plate for fixing the fibrous media.

Accordingly, the upper and lower ends of the elevating bar 320, the fibrous media fixing plate 350, the pressing rod 330, and the fibrous media 10 are moved up and down together, and the crimping rod 330 is moved upward. When compressing the 10, the fibrous media 10 is also the upper end is pulled to further compress the fibrous media 10.

In addition, when the pressing member 330 is moved to the lower portion of the fibrous media 10 is relaxed while the top of the fibrous media 10 is also moved to the lower portion so that the fibrous media 10 is more easily relaxed.

In addition, since the pressing rod 330 also has the effect of pulling down the fibrous media 10 while moving to the bottom, the free length generated while the upper end of the fibrous media 10 moves downward is evenly distributed in the entire fibrous media 10 It also has a function to make it possible.

After the inflow, the support rod 430 of the second side wall 420 may be discharged to the outside through the second treatment water flow port 422 formed on the opposite surface (see FIG. 11).

Meanwhile, although the moving paths of the backwasher and the treated water are shown together in FIG. 11, the backwashing air is supplied only at the backwashing, and since the flow of the treated water occurs only at the time of filtration, the backwashing process and the treated water simultaneously move the path as shown in FIG. 11. Does not seem to.

In addition, the filtration tank 200 is provided with a raw water inlet 201 through which raw water to be treated is introduced, a backwash water outlet 202 through which backwash water is discharged, and a treated water outlet 203 through which treated water is discharged.

The treated water outlet 203 is connected to the second treated water flow port 422 of the filtration module 400.

The operation of the present embodiment as described above will be described.

First, the filtration mode will be described with reference to FIG. 15.

The actuator 310 is driven to elevate the elevating bar 320 upwards, whereby the pressing rod 330 is moved upwards, and thus the fibrous material ((3) due to the relationship between the pressing rod 330 and the supporting rod 430). 10) is compressed.

By this operation, the fibrous media 10 is compressed in a zigzag form (vertical section form) biased to the upper portion, thereby forming a filter void.

Meanwhile, the raw water is introduced into the filtration tank 200 through the raw water inlet 201, and the foreign matter is filtered through the fibrous media 10. Then, the filtered raw water, that is, the treated water is passed through the first treated water flow port 421. After flowing into the second side wall 420, it is discharged to the treatment water outlet 203 through the second treatment water flow port 422.

At this time, the backwash water outlet 202 and the air inlet 411 are in a closed state.

Next, the backwash mode will be described with reference to FIG. 14.

The actuator 310 is driven to elevate the elevating bar 320 downward, whereby the pressing rod 330 is moved to the bottom, due to the relationship between the pressing rod 330 and the support rod 130, the fiber media (10) ) Is relaxed.

Therefore, the fibrous media 10 is changed to a relaxed state and forms a backwash void.

Meanwhile, air is supplied from the air supply means (not shown) to the air inlet 411 so that air is injected into the fibrous media 10 through an air injection port (not shown) formed in the support rod 430. Air injected from the air injection hole (not shown) is to shake off the fibrous media 10 so that foreign matter accumulated in the fibrous media 10 is more easily separated.

In addition, the backwash water is introduced into the filtration tank 200 from the raw water inlet 201 and discharged to the backwash water outlet 202 together with the foreign matter shaken from the fibrous media 10.

At this time, the treated water outlet 203 is in a closed state.

Meanwhile, in the second embodiment, the medial upper fixing part 450 is provided as the medial upper fixing means, and the medial lower fixing part 440 is provided as the medial lower fixing means.

However, as shown in FIG. 5, the fibrous media fixing moving plate 350 fixed to the elevating bar 320 may be provided as the upper media fixing means, wherein the top of the fibrous media 10 is for fixing the fibrous media It may be more preferable to be fixed to the moving plate 350 to move up and down together with the moving medium for fixing the fibrous media 350.
