The preferred embodiments of the present invention will now be described in more detail with reference to the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 3 is a schematic perspective view illustrating an example of a filtration tank having a rectangular strained type strainer according to an embodiment of the present invention. FIG. 4 is a cross- Fig.

As shown in Figure 3, the fiber filter of one embodiment of the present invention

A strainer (30) provided in the filtration tank and provided with a hollow portion therein, and having a plurality of filtrate inflow holes on the side thereof, a plurality of And a pore control unit (50) for controlling the pores of the fiber filter media by pressing or loosening the fiber filter material by pulling or pulling down the fiber filter material, wherein the strainer (30) has a rectangular plate shape And a plurality of fiber filter media 20 are tightly and tightly fixed to the outer sides of both sides of the rectangular strainer 30.

The strainer 30 must have a wide rectangular plate structure to maximize filtration efficiency. As shown in FIG. 2, in the case of the conventional cylindrical strainer, the side surface area constituting the filtration layer in the nature of the original is much smaller than that of the rectangular plate type strainer of the present invention. In the case of cylindrical type, it is a formula using the diameter (D) including the filter media and the height (H) of the filter media. The filtration area is calculated by DH. In the case of the rectangular filter type air gap control fiber filter according to an embodiment of the present invention, the filtration area is a formula using the number N of the plates, the lateral length L of the filter material, and the height H of the filter material as variables. * N * L * H. For example, the filtration area according to the shape of the filter media is as follows based on a filtration space having a length of 1 m, a length of 1 m, and a height of 2 m.

Circular: 0.9 m X H (2 m) = 5.65

Square: 0.9 m X 4 X H (2 m) = 7.20

Square plate type: 1.0 X 6.67 X 2 = 13.3

Accordingly, it can be seen that when using the rectangular plate type strainer according to the present invention, the filtration area is twice as large as that of the conventional circular strainer. This allows the same processing capacity to be achieved with only one filter placed in the same container, which saves manufacturing costs, reduces device size and footprint, and can save significant cost.

The strainer 30 is formed by densely forming a large number of filtrate inflow holes on both sides of the strainer 30 so that the raw water is filtered through the fiber filter media 20 and then flows into the filtrate inflow holes on both sides of the rectangular strainer- And drained to the bottom of the filtration water outlet (not shown).

The fiber filter material 20 of the present invention is fixed to the upper fiber material fixing part 60 and the lower fiber filter fixing part 40 so that the air gap control part 50 is driven to form a filtration gap on the outer circumferential surface of the strainer 30 .

It is preferable that the upper fiber material fixing portion 60 has a width narrower than that of the strainer 30 in order to make the fiber filter material 20 have a direction to cause the rectangular fiber type strainer 30 to be pressed toward the strainer 30. [ Alternatively, a through hole may be formed in the plate to hook the fiber filter media.

The upper fiber material fixing portion 60 of the present invention is a portion of the upper portion of the strainer 30 which is fixed to the piston 52 and receives the pulling motion of the piston 52, The lower fiber media fixing part 60 is fixed to the outside of the bottom of the strainer 30 inside the filtration tank 10.

The air gap control unit 50 is operated by a piston 52 coupled to the upper filter medium fixing unit 60 and is normally operated by pneumatic or hydraulic pressure and drives the piston to control the upper filter medium fixing unit 60 , And a cylinder (51) for controlling the pores of the fiber filter media upon backwashing and filtration. The cylinder (51) is fixed to the upper portion of the outside of the filtration tank (10) by a support. The movement of the piston 52 by the cylinder 51 may be performed by a simple linear motion or by a rotary cylinder in which linear motion and rotation are similar.

The configuration of the air gap control unit 50 is not limited to the configuration of the cylinder 51 and the piston 52 but the upper fiber material fixing unit 60 may be pulled to press the fiber filter media 20 around the strainer 30 Other possible structures may be employed in accordance with the present invention, as long as they are capable of being disengaged or disengaged.

The filtration and backwashing operation of the fiber filter of the present invention will be described below. First, the raw water to be treated is fed into the inside of the filtration tank 10, and then filtered by a fiber filter. The filtration ability of the fibrous filter material 20 is determined by the pores formed by the fibrous filter material 20, and the pores are formed by the tensile tension of the fibrous filter material 20. In the present invention, the tensile tension of the fiber filter material 20 is formed by the movement of the piston 52 by the gap control unit 50. That is, when the piston 52 rises, the upper filter material fixing part 60 fixed to the piston 52 pulls the fiber filter material 20 upward, and tensile tension is formed, and the tensile tension of the fiber filter material 20 is The internal voids are reduced to form filtration voids.

Next, the backwash process can be performed automatically or manually, and the backwash water discharge valve (300), the fiber filter, and the backwash water drain pipe (100) are closed by closing the raw water valve of the fiber filter . When the backwashing is performed, the piston 52 of the air gap control unit 50 is lowered to remove the tension of the fiber filter media 20. At this time, when the piston 52 descends, the upper fibrous filter material fixing portion 60 fixed to the piston 52 is lowered, so that the fiber filter media 20 is loosened and the inner cavity of the fiber filter material 20 is expanded. When the fibrous filter material is loosened, the fibrous filter material 20 is backwashed by the pressurized water and compressed air ejected from the strainer 30. The water introduced through the treated water drain pipe 300 is blown into the fiber filter media 20 through the strainer 30 to back up the fiber filter media 20 and return to the inside of the fiber filter media 20, Is drained to the outside through a reverse water drainage pipe. When the contaminants trapped in the fibrous filter material 20 are sufficiently desorbed and the backwashing is completed, the filtration process is switched again.
