Description

TECHNICAL FIELD [0001] The present invention relates to a fibrous filter medium,

The present invention relates to a warp spiral fiber filter fixing plate and a fiber filter using the same. More particularly, the present invention relates to a fiber filter fixing plate in which upper and lower portions of a fiber bundle composed of a fiber filter medium are fixed, To a warp spiral fiber filter fixing plate and a fiber filter using the warp spiral fiber filter fixing plate capable of improving the filtration efficiency by filling the fiber filter media with a uniform density without a space between the fiber bundles.

Generally, a filter is a device for discharging clean treated water by filtering a contaminated raw water with a filter including a filter medium, and is gradually becoming larger in size for the treatment of wastewater, filtration of a large river, filtration of a factory wastewater .

Inorganic materials such as sand, anthracite and anthracite have been mainly used as filter media. Such a filter material can be easily obtained, and particles smaller than the size of pores formed by the filter material can be removed. However, the filter layer formed by the filter material is limited in the vicinity of the surface layer This leads to a rapid increase in the filtration resistance due to the clogging of the pores, which is a disadvantage of frequent backwashing.

In order to overcome the disadvantages of the conventional filtration apparatus using inorganic material as a filter medium, the present applicant has developed a pore controllable filter using a fiber filter material composed of a fiber bundle having fine filaments as a filter material. Such a pore-controlled fiber filter is small and light in weight, and the pore formed by the filament is easily controlled by the physical control, so that not only the filtration performance is excellent, but also the washing is easy and the life of the filter material is long. Particularly, the removal efficiency of each particle size, the removal efficiency of SS and BOD, etc., are much higher than other filtration methods and thus attracting much attention.

As an example of the above-mentioned void control fiber filter, the applicant of the present invention has disclosed in Korean Patent No. 813114 that a fiber filter material composed of a bundle of fiber yarns wrapped around a perforated pipe is pulled upward and compressed to reduce a gap, And then the filter is backwashed with compressed air and pressurized water. In this type of fiber filter, the fiber filter material is fixed between the upper and lower fiber filter media fixing plates. In the conventional fiber filter media fixing plate, as shown in FIG. 2, a plurality of fiber filter media fixing bars 25 formed at predetermined intervals are radially formed , And a fiber filter material 20 composed of a bundle of fiber yarns is fixed to each of the fiber filter material fixing rods 25. However, when such a flat fibrous filter medium fixing plate is used, a lot of void spaces are formed between the fibrous filter media 20 caught by the adjacent fiber filter medium fixing bracket 25. As a result, the unfiltered raw water can be introduced into the strainer 30 as an empty space between the fiber bundles, so that the water quality of the treated water may be deteriorated and the fiber filter media may not be packed compactly at a uniform density. The processing efficiency is lowered.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fiber filter capable of filling a fiber filter material at a uniform density without a space between the fiber filter media.

That is, each of the fibrous filter media fixing rods 45 and 65 may be formed of curved rods. After the fiber filter media 20 is mounted on the warped spiral fiber filter media fixing rods 45 and 65, the fiber filter media fixing rods 45 and 65 of the upper and lower fiber filter media fixing plates 45, (For example, reference numeral 47 in FIG. 3) may be mounted on the end of the fiber filter material to prevent detachment of the fiber filter material.

Another aspect of the present invention relates to a fiber filter including the warp spiral fiber fixing plate described above. An example of a fiber filter provided with an inclined spiral fiber filter fixing plate of the present invention is shown in Fig.

Referring to FIG. 1, the warp spun fiber media fixing plates 40 and 60 of the present invention are used to fix the fiber filter material 20 to the outside of the strainer 30 in the filtration tank 10. The filtration tank 10 is connected to a raw water inflow pipe 200 for inflow of the raw water to be treated and a reverse wastewater discharge pipe 100 for discharge of reverse wastewater. The installation positions of the raw water inlet pipe 200 and the reverse water drainage pipe 100 are not particularly limited and may be formed on the upper side or the upper side of the filtration tank 10 and the valves 120 and 220 formed in the respective pipes The filtration and backwash path are selected.

An air inflow pipe 400 for injecting backwash air is connected to the lower end of the filtration tank 10 and the treated water discharge pipe 300 extending to the outside of the filtration tank 10 is connected to the bottom. A hole (31) is formed in the upper portion of the filtration tank (10) to be coaxially inserted. The hole 31 guides the piston 52 of the fiber filter medium cavity control portion 50 and supports the upper end of the strainer 30 with the piston 52.

The air gap control unit 50 is constituted of a cylinder 51 and a piston 52 which are normally operated by pneumatic or hydraulic pressure. The cavity control unit 50 is a mechanical unit that drives the piston 52 to receive the guide of the piston guide 41 and the cylinder 51 is fixed to the upper portion of the outside of the filtration tank 10 by a support 53 . The movement of the piston 52 by the cylinder 51 may be performed by a simple linear motion, or alternatively by a rotary cylinder in which linear motion and rotational motion coincide.

The upper fiber filter fixing plate 60 of the present invention is a portion which is fixed to the piston 52 at the upper end of the upper portion of the strainer 30 in the filtration tank 10 and receives the pulling motion of the piston 52, The lower fibrous filter medium fixing plate 40 is a portion fixed to the outside of the bottom of the strainer 30 in the filtration tank 10.

The fiber filter media 20 of the present invention is fixed to the upper fiber filter media fixing plate 60 and the lower fiber filter media fixing plate 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. The upper fibrous filter medium fixing plate 60 and the lower fibrous filter medium fixing plate 40 are formed to have a diameter smaller than that of the strainer 30 in order to make the fiber filter media 20 have a directionality to be pressed against the strainer 30, The fibrous filter medium fixing plate 60 and the lower fiber filter medium fixing plate 40 need not always have the same diameter.

5, the upper fiber filter medium fixing plate 60 and the lower fiber filter medium fixing plate 40 may be formed in a three-dimensional three-dimensional structure, and the fibers of the upper fiber filter medium fixing plate 60 The filter media fixing members 65 of the lower fiber filter media fixing plate 40 may be tapered outwardly downward.

In the fiber filter of the present invention, various kinds of piping can be designed and modified as needed. For example, raw water with a low degree of contamination may be used as backwash water. In such cases, the piping structure must be changed.

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 filtering ability of the fiber filter media 20 is determined by the pores formed by the fiber filter media 20, and the pores are formed by the tensile tension of the fiber filter media 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 fibrous filter material fixing plate 60 fixed to the piston 52 pulls the fiber filter material 20 to form a tensile tension, and the tensile tension of the fiber filter material 20 The pores are reduced to form filtration pores. In this case, when the rotary cylinder is used to simultaneously generate the linear motion and the rotary motion of the piston 51 of the cavity control unit 50, when the piston 52 is lifted, Is pulled around the outer peripheral surface of the strainer (30). Since the fibrous filter material can be fixed at a high density at a uniform density without voids in the warp spiral fiber filter fixing plate of the present invention, the filtration efficiency can be remarkably improved.

Next, the backwashing process of the fiber filter will be described. The backwash process can be performed automatically or manually. The raw water valve 220 of the fiber filter is closed and the backwash water drain valve 120 is opened to open the treatment water drain pipe 300, the fiber filter, and the reverse water drain pipe 100 Is formed. When the backwashing is performed, the piston 52 of the gap control unit 50 is lowered to remove the tension of the fiber filter media 20, whereby the fiber filter media 20 can be easily washed off from the water sprayed from the strainer 30 It is vibrated and rubbed backwards. At this time, air is injected through the air inflow pipe 410 at the bottom of the fiber filter media 20, and the backwashing efficiency is improved. 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 the reverse water drainage pipe (100). If it is determined that the suspended particulate matter trapped in the fibrous filter material 20 has been sufficiently desorbed, the process returns to the filtration step.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Therefore, the scope of protection of the present invention is not limited to the above-described embodiments, but should be defined in the following claims and their equivalents.
