As shown in FIG. 4, raw water is filtered through the fibrous media layer 22 and introduced into the strainer 21. Therefore, the quality of the filtrate is determined by the filtration pores of the fibrous media layer 22. In the present invention, by controlling the degree of compression of the fibrous media layer 22, there is a feature to control the filtration voids.

To this end, the apparatus for compressing the fibrous media layer 22 is the pressure plate 23 of the present invention, and the pressure plate 23 is formed on both sides of the strainer 21 with the fiber media layer 22 interposed therebetween. Frame.

It is formed in the frame of) to form a frame width smaller than the main frame 230 to prevent the oil path is blocked.

The pressure plate 23 is configured such that inflow and outflow of water is formed in all directions, but in actual filtration, water flows into the side of the pressure plate 23 and water flows out from both side surfaces as shown in FIG. 4.

Therefore, the main frame 230 must have a through-hole or a frame structure through which water flows by itself so that a flow path is formed from the outside into the main frame 230.

In the embodiment of the present invention, the flow path in the pressure plate 23 flows into the main frame 230 through the through hole formed in the main frame 230 as shown in FIG. 4 and the inner frame 231. It is directed to the fibrous media through) and has a reverse flow as shown in FIG.

The backwashing air injection pipe 320 of the present invention is a pipe connected to the backwashing air injection pipe 321 formed on the lower side of the strainer 21, as shown in FIG. It supplies to the officer 321.

The backwashing air injection pipe 321 has a backwashing air injection through hole 321-1 for injecting outside air into the fibrous media layer during backwashing, and is formed along the bottom side of the fibrous mediating layer 22, so that the outside air is backwashed. It is to be evenly sprayed on the fibrous media layer 22.

Hereinafter, the compression motion of the unit filter 20 will be described with reference to FIG. 6. The pressing motion of the unit filter 20 is composed of the pressing plate 60 and the actuator 25 of the present invention, as shown in the figure, the actuator 25 generates a driving force and transmits it to the pressing plate 60. The pressing plate 60 is a means for compressing the driving force transmitted by the side plate to the unit filter 20.

Therefore, in the present invention, the force is transmitted in the order of the actuator 25, the pressing plate 60, the unit filter 20.

The pressing plate 60 is a plate for pressing the other side of the pressing plate 23 as a whole while supporting one side of the pressing plate 23 on one side wall of the filtration tank.

Since the pressing plate 60 also has a movement path in the same direction as the unit filter 20, the sliding path and the sliding guide are formed in the filtration tank 10 and the pressing plate 60 so that the movement path is guided. desirable.

One side of the unit filter 20 is supported by the pressing plate 60 while being supported on the inner wall of the filtration tank 10 while the other side is compressed. This is purely a matter of choice for increasing the compression efficiency of the unit filter 20, it may be formed to form a pressing plate so that both sides are compressed.

The actuator 25 is composed of a cylinder 25-1 and a transition transmission link 25-2 to generate a driving force generating or removing side plate pressing force.

In general, as the driving force generating unit of the actuator 25, a motor and a gear assembly are used in addition to the cylinder 25-1. However, in the embodiment of the present invention, the pneumatic cylinder is configured as the actuator 25. The device may be selected.

Since the transfer link 25-2 generally requires the cylinder 25-1 to be formed on the outside of the filtration tank 10, the cylinder 25-1 of the cylinder 25-1 up to the pressing plate 60 inside the filtration tank 10. As a device for transmitting a driving force, it is generally composed of a multi-joint link assembly for converting the vertical displacement amount to the horizontal displacement amount, in the embodiment of the present invention, as shown in FIG. Implemented as a link clause that converts to.

As described above, the present invention is formed in such a structure so that the filtration plate 60 is pressed by the actuator 25 during filtration so that the fibrous media layer 22 is the pressure plate 23 as shown in FIG. 4. Sandwich is pressed to form a filter cavity, and when backwashing, as shown in Figure 5 releases the pressing force of the pressing plate 60 with the actuator 25, the pressing plate 23 is the fiber media layer 22 ) To form a backwash cavity.

On the other hand, as described above, the filtered water drainage pipe 300 and the back-air air inlet pipe 320 is connected to each unit filter 20, the movement of each unit filter 20 by the driving of the pressing plate 60 It is preferable to form a corrugated pipe as shown in FIGS. 1 and 2 so as to be interlocked with the length change between the generated strainer 21 and the filtration tank 10.

The basic structure of the present invention is made as described above, and the present invention arranges a plurality of the unit filters 20 to collectively compress or relax the filter in the form of a filter press as shown in FIGS. 7 and 8.

As a result, the unit filter 20 travels a predetermined distance on the rail 260 formed in the filtration tank 10. However, in order to move the movement of the unit filter 20 while maintaining the unit filters 20 at equal intervals when the plurality of unit filters 20 are arranged, the movement space is actually limited as shown in FIG.

That is, the unit filters 20 of the present invention are coupled to each other by the unit plate link section 211 to limit the movement distance during the compression and relaxation movement of each unit filter 20.

The unit plate link section 211 is a link section coupled to each one of the unit filter 20, each unit plate link section 211 is a mutual chain coupling.

The unit plate link section 211 is a bar formed with a through hole on one side and a long hole on the other side, the unit filter 20 to which the unit belongs is fixedly screwed to the through hole, the unit filter on the neighboring side In 20, the through-hole coupling screw is coupled to the long hole to form the unit plate link assembly 212, and the sliding to secure the sliding interval by the length of the through-hole screw long hole.

When the unit plate link section 211 is coupled to each unit filter 20 like a continuous chain, each unit filter 20 is moved by the length of the long hole of the unit plate link section 211 during compression and relaxation.

In the embodiment of the present invention, the unit plate link section 211 is to be coupled to the upper filter frame of each unit filter 920.

By the unit plate link section 211, the movement distance of each unit filter 20 is the long hole of the unit plate link section 211, starting from the position where the filter frame 200 of each unit filter 20 is in contact Will move by the length.

On the other hand, the filter frame width (t) of the unit filter 20 affects the moving distance of the pressure plate for sandwiching the fibrous media layer 22 sandwiched.

That is, referring to FIGS. 3 and 8, the compressible widths of the strainer 21, the fibrous media layer 22, and the pressure plate 23 are defined within the filter frame width t of FIG. 8.

As described above, the filtration pores of the fibrous media layer 22 are formed by the pressing of the pressure plate 23, and for this reason, the filtration pores of the fibrous media layer 22 are formed at a degree of compression of the crimping plate 23. It is self-evident to be determined by.

Therefore, if the filter frame width (t) can be varied, the degree of compression can be adjusted, which is to change the filtration pores of the fibrous media layer 22 to change the filtration performance of the present invention. .

In order to realize this, the present invention comprises a filter performance controller capable of varying the filter frame width t as shown in FIG.

In practice, the filter performance regulator does not directly change the filter frame width t, but forms a kind of a contact stopper on the filter frame 200 so that the contact distances between neighboring unit filters 20 are adjusted. .

The filter performance regulator is formed on the vertical side of the filter frame 200 and is composed of a pore adjusting rod 223, a trapezoidal adjustor 228, a case 229, a distance adjusting pin 226.

The distance adjusting pin 226 is a pin protruding outward in the width direction of the filter frame 200 through the pin through hole 227 of the case.

The distance adjusting pin 226 is slid into and out of the pin through hole 227, the distance in contact with the trapezoidal adjuster 228 is moved to the inside of the case is limited.

The filtration performance regulator of the present invention is formed in such a structure and the trapezoidal adjuster 228 is raised and lowered inside the case by adjusting the length of the pore adjusting rod 223 with the lever 224.

Accordingly, the distance adjusting pin 226 is adjusted to the distance that can be moved inwards depending on the position of the trapezoidal adjuster 228, when adjusting the position of the trapezoidal adjuster 228 in the filter frame width direction The protruding length is controlled.

Therefore, the device of the present invention can adjust the contact distance between each filter frame 200 with the lever 224, it is possible to control the voids formed by the fibrous media layer 22.

On the other hand, the present invention is to form the filter pores by pressing the fibrous media layer 22 during filtration as described above.

Therefore, the filtration performance of the present invention is determined by the degree of compression of the fibrous media layer 22.

On the other hand, when the length of the fibrous media layer 22 is increased by long-term use, the voids formed by pressing are formed differently from the first and thus the filtration performance is reduced.

The present invention further includes a fibrous media gap control device for tensioning the fibrous media layer 22 upward as shown in FIGS. 2 and 3 in order to correct the filtration performance change due to such use.

The fibrous median pore control device tensions the fibrous media layer 22 on the upper side to maintain the initial tension when the tension of the fibrous media layer 22 changes with time so that the filtration performance can be kept constant at all times.

Furthermore, such a fibrous median pore control device may be driven at every filtration and backwash to contribute to the formation of the voids in the fibrous media layer 22.
