BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a filtration filter for use in a water treatment filtration apparatus,

The present invention relates to a filtration filter used in a water treatment filtration apparatus, and more particularly, to a filtration filter used in a water treatment filtration apparatus, more specifically, by forming an inflow hole only in an upper portion of a tubular body so that a water pressure can be concentrated on the upper portion, It is possible to efficiently purify the raw water and to efficiently purify the raw water. In addition, even if the filtration member is finely stretched for a long period of time, the filtration member is pushed outwardly through the tension means so as to be taut, The present invention relates to a filtration filter for use in a water treatment filtration apparatus which can always expect a precise filtration function of a filtration member even when used for a long period of time.

Generally, a filter medium for filtering out impurities (sludge or debris) contained in water is installed inside a container of a water treatment filtration apparatus used for water treatment of water, wastewater, waste water, wastewater, groundwater, seawater and the like.

Conventional filter media used in such a water treatment filtration device include a cartridge-type filter medium in which a yarn made of polyester (PE: Polyester) is wound tightly to form a cylindrical shape or a large number of filter paper cut in a ring- Respectively.

However, since the conventional filter medium constructed as described above is generally used once, it can not be reused any more and needs to be replaced with a new filter medium. Thus, there is a problem that the replacement cost and replacement time are wasted.

In addition, the conventional filter medium used once, not only takes a separate cost when disposed, but also has a problem of causing environmental pollution as industrial waste.

In order to solve the above problems, the applicant of the present invention has developed and proposed "a filtration apparatus for water treatment using a filter material for water treatment which can be repeatedly regenerated (Application No. 10-2010-0024360)".

However, the above-mentioned "filtration apparatus for water treatment using a filter material for water treatment which can be repeatedly regenerated " (Application No. 10-2010-0024360) has a filter medium compression plate for pressurizing the filter material so that impurities remaining in raw water flowing into the inside can be easily filtered Since the separate power means (cylinder for lifting and lowering the compression plate) for vertically ascending and descending is provided, the structure of the apparatus is complicated, so that it is difficult to manufacture the apparatus and the maintenance cost for maintenance and repair of the apparatus is high.

In addition, the above-mentioned "water treatment filtration apparatus using water repelling filter material capable of repeatedly regenerating (Application No. 10-2010-0024360)" is intended to provide convenient maintenance of the apparatus through a filter material capable of repeatedly regenerating, The rubber packing formed on the outer circumferential surface of the lowering filter medium was lost due to repeated rubbing with the container, and the rubber packing had to be frequently used for replacement.

Especially, when the rubber packing resembling due to the friction inside the container can not be smoothly replaced, airtightness can not be maintained between the inner circumferential surface of the container and the rubber packing, and the filter material is discharged (lost) to the upper portion of the filter medium compression plate The function of the filter medium is lost and the water treatment function of the device is deteriorated.

In order to solve the above problems, the present applicant has developed a filtration filter (Application No. 10-2010-0128342) used in a water treatment filtration apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A filtering filter used in a water treatment filtration apparatus according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a filtration filter used in the water treatment filtration apparatus according to the embodiment of the present invention, FIG. 2 is an exploded perspective view of a filtration filter used in the water treatment filtration apparatus shown in FIG. 1, 3 is a perspective view of a filtration filter used in the water treatment filtration apparatus according to another embodiment of the present invention, and Fig. 4 is a view showing the state of use of the filtration filter used in the water treatment filtration apparatus shown in Fig.

As shown in the drawing, the filter 100 used in the water treatment filtration apparatus according to the embodiment of the present invention includes a tubular body 10, an auxiliary tubular body 20, and a filtration member 30.

As shown in FIGS. 1 and 2, the tubular body 10 has a plurality of inlet holes 12 through which raw water flows into the upper portion, and a drain hole 13 Is formed.

Here, since the inlet hole 12 into which the raw water flows is formed only on the upper surface of the tube 10, the water pressure can be easily concentrated, and the concentrated water pressure can smoothly flow the raw water into the plurality of inflow holes 12. [ do.

The tubular body 10 is installed in an enclosed container (not shown) of the water treatment filtration device to prevent rotation.

As shown in FIGS. 1 and 2, the auxiliary tubular body 20 has a cylindrical shape, and is positioned at a lower portion of the tubular body 10.

The auxiliary tubular body 20 is installed in a sealed container of the water treatment filtration device and is rotated so that the filtration member 30 to be traversed due to rotation of the auxiliary tubular body 20 is inserted into the tubular body 10, (20).

1 and 2, the filtration member 30 is wound together with the auxiliary tube 20 via the tubular body 10 and is inserted into the inlet hole 12 of the tubular body 10 And is configured to have fine voids therein so as to filter off impurities remaining in the raw water to be introduced.

The filtering member 30 of the filtering filter 100 of the water treatment filter according to the embodiment of the present invention is not limited to the mesh member or the nonwoven fabric.

4A, the raw water passes through the filtration member 30 to be separated from the tubular body 10, as shown in FIG. 4A, by contacting the filtration member 30 to the outer circumferential surface of the tubular body 10, The impurities remaining in the raw water are filtered while passing through the minute air gaps in the filtration member 30 and the purified water filtered by the impurities is discharged to the outside of the tubular body 10 And is discharged to the outside through the discharge hole (13).

Since the filtering ability of the filtering filter 100 used in the water treatment filtration apparatus of the present invention can be adjusted according to the void density of the filter member 30, the user can adjust the amount of impurities remaining in the raw water It is preferable to select and use the filter member 30 having a suitable air gap density.

4B, when the auxiliary tubular body 20 is continuously rotated, the auxiliary tubular body 20 and the filtration member 30 passing through the tubular body 10 are continuously connected to the auxiliary tubular body 20, The portion of the raw water that is trapped in the raw water and accumulated on the filtration member 30 is transferred without being stopped at one place in the process of flowing the raw water into the tubular body 10 The process of accumulating the impurities remaining in the raw water through the filtration member 30 can be continuously performed.

If the filtration member 30 is stopped without being circulated and rotated, the impurities are concentrated on the portion of the filtration member 30 that is in close contact with the inlet hole 12 of the tube 10, If the impurities are concentrated near the inlet hole 12 of the tube 10 through which the raw water flows, it is difficult to distribute the raw water to the filter member 30 due to the impurities, The water purification ability is inevitably reduced.

Accordingly, the filtration member 30 allows the auxiliary tubular body 20 and the tubular body 10 to be circulated and rotated continuously.

The driving unit (not shown) that rotates the auxiliary tube 20 and the brush roll 51 of the impurity cleaning unit 50 to be hounded is provided with a driving unit Motor and the like.

The auxiliary tubular body 20 is formed at an equal interval on the outer periphery of the auxiliary tubular body 20 and is spaced apart from the auxiliary tubular body 20, The other end of which is engaged with the elastic plate 41 to elastically support the elastic plate 41. The other end of the elastic plate 41 is fixed to the outer peripheral surface of the auxiliary tube 20, And a plurality of rotation protrusions 43 formed on one side surface of the elastic plate 41 and contacting the filtration member 30, .

That is, the filter member 30 made of a normal mesh or nonwoven fabric is finely stretched when it is used for a long period of time. Due to such elongation, a minute gap may be formed between the filter member 30 and the tube body 10 Impurities remaining in the raw water may flow into the inside of the tube 10 through the gaps, which may make it difficult to purify the raw water.

4A, the elastic plate 41, which is elastically supported by a plurality of the elastic springs 42, can be elastically supported by the tension member 40 even if the filter member 30 is extended for a long time by using the filter member 30 for a long time. The filter member 30 is always kept tight and firmly attached to the tubular body 10 so that the tubular body 10 and the filtration member 30 are tightly adhered to the tubular body 10, It is possible to expect a precise filtration function of the filter member 30 at all times even if the filter member 30 is used for a long period of time.

The raw water is purified by collecting the impurities remaining in the raw water through the filtration member 30 rotating the tubular body 10 and the auxiliary tubular body 20 continuously and rotating the filtration member 30 through the impurity cleaning unit 50, It is possible to efficiently purify a large amount of raw water quickly.

The purification process of raw water may be performed using the filtration filter 100 used in the water treatment filtration apparatus according to another embodiment of the present invention as described below.

4A, the auxiliary tubular body 20 is rotated so that the auxiliary tubular body 20 is rotated, as shown in FIG. 4A, after the filtering filter 100 used in the water treatment filtration apparatus of the present invention is installed in a closed container (not shown) And the filter member (30) wrapped around the tubular body (10) are continuously rotated and transferred,

At this time, when raw water flows into the container, raw water in which impurities remain due to water pressure passes through the filter member 30 and flows into the plurality of inflow holes 12 formed in the tube body 10, The remaining impurities are filtered while passing through the fine voids in the filtration member 30. The purified water filtered by the impurities is discharged to the outside through the discharge hole 13 of the tubular body 10. [

4A, the elastic plate 41 elastically supporting the elastic spring 42 of the tension unit 40 installed on the auxiliary tubular body 20 is positioned so that the filter member 30 is taut The filter member 30 which is circulating and rotating is always kept tight and tightly adhered to the tubular body 10 to prevent the gap between the tubular body 10 and the filtration member 30 from being generated in advance Of course.

4B, the filtration member 30 continuously circulated through the auxiliary tubular body 20 and the tubular body 10 is conveyed to the impurity cleaning unit 50. At this time, the filtration member 30 The impurities filtered on the surface of the brush roll 51 come into contact with the brushes 51a of the brush roll 51 to scrape the filtration member 30 to separate the impurities filtered by the filtration member 30. The separated impurities fall freely, Impurities contained in the dust collecting part 52 are introduced into the connecting pipe 53 and the introduced impurities are discharged to the outside through the connecting pipe 53.
