Description

{RAINWATER WIRBEL FEIN FILTER}

The present invention relates to a rainwater filter, and more particularly, to a rainwater filter capable of effectively removing foreign matter contained in an initial rainwater by improving its structure, facilitating installation, and easily replacing or repairing the rainwater filter.

In general, rainwater is discharged to rivers or the sea through rainwater pumping stations or sewer pipes and is not used as domestic water. It causes flood damage, resulting in depletion of groundwater and streamlining of rivers.

Despite rainfall above the world average rainfall, Korea has not been able to effectively use rainwater and is classified as a water-scarce country.

In Korea, rainfall is concentrated in summer, and most of the rainfall is discharged to rivers or the sea in rural or mountain villages.

Although the city operates a rainwater pumping station, the existing rainwater pumping station does not utilize rainwater, but focuses on the drainage of rainwater as a disaster prevention facility against flooding and flood.

In recent years, it has been known that research is underway to collect rainwater effectively, but in reality it is concentrated on collecting rainwater collected on the ground in one place, and measures and measures for using collected rainwater It is relatively neglected.

Although attempts have been made to solve the above-described problems in many ways, there are still insufficient processes and management costs in terms of efficiency.

Accordingly, in order to overcome such a problem, this rainwater management facility is disclosed in Patent Registration No. 10-1043814 (name: rainwater management facility), in which the present applicant has applied for a patent and pre-registered.

As shown in FIG. 1, the rainwater management facility of the prior art includes: a screen filter for primarily producing filtered water; A sedimentation tank for producing secondary filtrate water; A treatment water tank in which the filtered water of the settling tank is stored overflow; And a pump for transferring the filtered water in the treated water tank.

In this prior art, the screen filter is configured such that the rainwater flows in a tangential direction through the inflow portion, the rainwater containing the foreign matter having a certain volume or more is discharged through the drainage portion, and the filtered water containing foreign substances smaller than a certain volume is discharged through the filtered water outlet portion do. The screen filter member is provided in the flow path space formed on the inner side to filter foreign matters.

However, such conventional prior arts have the following problems.

First, since the inlet portion, the drain portion, and the filtrate outlet portion constituting the filter are disposed in one body, it is difficult to smoothly install the filter due to interference with the outside during installation.

Secondly, when the rainwater passes through the filter, since the initial rainwater contains a large amount of foreign matter, this initial rainwater is also filtered, which makes it difficult to obtain high quality filtered water.

Third, when the screen filter member mounted inside the filter is replaced or cleaned, it is difficult to draw out the filter member to the outside.

Fourth, since the inlet portion of the filter, the outlet portion of the filtered water, and the flange of the outlet portion are perpendicular to the paper surface, the pipe connected thereto must be installed horizontally so that when the water is supplied to the filter, , And a pump must be installed separately if necessary.

Fifth, when installing the filter in the ground, if the upper part of the filter does not coincide with the height of the ground, or if it should protrude to the upper part of the ground, additional work such as lifting up the filter itself is required, There is a problem.

Prior Art 1: Korean Patent Registration No. 10-1043814 (Name: Rainwater Management Facility)

Disclosure of Invention Technical Problem [8] The present invention has been made to solve the above-mentioned problems occurring in the prior art.

First, by improving the structure of the filter, it is possible to rotate the inlet portion, the drain portion, and the filtrate outlet portion when they are combined with each other in an independent structure. Provide a filter.

Second, by improving the structure of the filter member, it is possible to prevent the initial storm from passing through the filter member, thereby preventing the initial storm, which contains a large amount of foreign matter, from flowing into the storage tank, thereby obtaining a filtered water of good quality.

Third, the present invention provides a filter capable of easily performing replacement or cleaning of the filter member by facilitating the outward drawing of the screen filter member mounted inside the filter.

Fourthly, the present invention provides a strainer in which the inlet connected to the filter, the outlet of the filtered water, and the flange of the outlet are inclined so that the pipe connected thereto is also tilted so that the storm can flow naturally into the inside of the filter without any power.

Fifth, a structure is improved so that an extension pipe can be coupled to an upper portion of the filter, thereby providing a filter that can easily height the filter height when the filter is installed, or to protrude upward.

Hereinafter, a rainwater filter according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 9, in the rainwater filter 1 proposed by the present invention, the rainwater introduced into the rainwater through the inflow pipe 3 forms a vortex due to the centrifugal force and flows into the upper housing ; 5);

An intermediate housing (9) rotatably coupled to a lower portion of the upper housing (5) and having a flow path for rainwater flowing downward, and a filtered water outflow pipe (7) for discharging rainwater to the side of the flow path;

A filter member 15 detachably disposed on the inside of the intermediate housing 9 to filter foreign matter of rainwater flowing to the filtered water outlet pipe 7; And

In the rainwater filter (1) having such a structure,

The upper housing 5 has a cylindrical shape, and the upper and lower portions have an open shape, and a rim 17 having a predetermined width is formed along the circumferential direction at a lower portion thereof, thereby forming a first through hole 19 in the middle Rainwater can fall.

An inlet pipe 3 through which rainwater flows is connected to one side of the upper housing 5. Accordingly, the rainwater can flow into the inside of the upper housing 5 through the inflow pipe 3, and the inflowed rainwater falls downward through the first through-hole 19.

At this time, the inlet pipe 3 is connected to one side of the circumferential surface of the upper housing 5, not to the intermediate portion.

Therefore, the rainwater flowing into the inside of the upper housing 5 through the inflow pipe 3 comes into contact with the inner side surface and rotates along the circumferential direction along the wall surface, and gradually flows down along the spiral trajectory while falling downward. Respectively.

At this time, a plurality of deflective ribs 21 are arranged on the inner side surface of the upper housing 5 in a state where they are spaced apart from one another along the circumferential direction, and are formed long in the vertical direction.

Therefore, the rainwater flowing into the inside of the upper housing 5 through the inflow pipe 3 collides with the plurality of deflecting ribs 21 while rotating spirally along the inner side, and by this collision, Foreign substances having a relatively large size, for example, leaves, etc., collide with the deflector ribs 21, so that they move from the vicinity of the inner wall to the first through-hole 19 in the middle, .

In this way, when foreign matter having a relatively large size continuously rotates spirally along the inner surface of the upper housing 5, it may be deposited on the rim 17 of the inner side adjacent position, The foreign substances can be moved to the intermediate first through hole 19 without being deposited on the rim 17 and discharged.

A cover 23 is detachably mounted on the upper portion of the upper housing 5, and the cover 23 has a cylindrical shape with its lower portion opened.

A handle 25 capable of handling the filter member 15 is integrally connected to the lower portion of the cover 23.

The handle 25 includes a pair of frames 27 spaced apart from each other by a predetermined distance; An upper frame (29) connecting the upper portions of the pair of frames (27) to each other and fixed to the bottom surface of the cover (23); And a lifting lug 31 for picking up the filter member 15 by connecting the lower portions of the pair of frames 27.

The lifting lug 31 has an inclined shape at both ends 33 as it is bent upward. Both ends 33 of the leaf ring lug 31 can be inserted into the coupling grooves formed on the upper portion of the filter member 15, respectively.

The user can remove the filter member 15 from the upper housing 5 by lifting the cover 23 and lifting the handle 25 and conversely by covering the cover 23, Into the interior of the upper housing 5 and the filter element 15 can be engaged in place.

At this time, the handle 35 is mounted on the upper surface of the cover 23 to easily lift the cover 23. Both ends 37 of the handle 35 are inserted into the cover 23 through the holes h formed in the cover 23. Both ends 37 of the handle 35 are bent so that they are caught by the holes h of the cover 23 and are not pulled out to the upper portion even when the knob 35 is lifted.

Therefore, the user can hold the handle 35 to lift the cover 23. [ Of course, when the knob 35 is not used, the knob 35 can be exposed at the upper end of the cover 23 only at the portion where both ends 37 are inserted into the inside of the cover 23,

The cover 23 may be fixed to the upper housing 5 by a plurality of eye bolts 39 while being mounted on the upper housing 5. Accordingly, when the user needs to lift the cover 23 for cleaning the filter member 15, the user can lift the cover 23 by first removing the eye bolt 39. [

A first flange f1 protrudes from a lower portion of the outer circumferential surface of the upper housing 5. The flange f1 has a second flange f2 protruding from the upper surface of the outer circumferential surface of the intermediate housing 9, And they can be fixed to each other by bolts.

Since the upper housing 5 and the intermediate housing 9 are independent from each other and are coupled by the first and second flanges f1 and f2, the inlet pipe 3 or the filtrate water outlet pipe 7 The upper housing 5 or the intermediate housing 9 can be rotated appropriately in order to avoid the interference with the external obstacle.

At this time, since a plurality of slots are formed on the second flange f2, the upper housing 5 or the lower housing 13 can be fixed at an arbitrary position by appropriately rotating the bolts and then fastening the bolts.

The intermediate housing 9 has a shape similar to that of the upper housing 5, and has a cylindrical shape with open top and bottom openings.

That is, the second flange f2 is protruded on the outer circumferential surface of the upper portion of the intermediate housing 9, and the intake plate 42 is formed on the lower inner circumferential surface of the intermediate housing 9 by arranging ring plates having a constant width along the circumferential direction . A second through hole (44) is formed in the middle of the water intake plate (42), so that rainwater can fall down.

A filtering water outlet pipe 7 for discharging rainwater is connected to the outside of the intermediate housing 9 through a settling tank (or a storage tank). Therefore, the rainwater passing through the filter member 15 from the inside of the intermediate housing 9 can be discharged through the filtered water outflow pipe 7.

The filter member 15 is mounted on the inside of the intermediate housing 9 so as to filter the impurities contained in the rainwater falling from the upper housing 5.

The filter member 15 may include various filter members, but preferably includes a double walled filter member of STS mesh type.

At this time, the filter member 15 can have various mesh sizes, for example, a 0.28 mm mesh.

Therefore, by adopting the STS mesh type filter member 15, the filtration efficiency is good and the durability is strong, so that the replacement is not necessary and the maintenance cost can be reduced.

The filter member 15 has a double wall structure and has a tapered shape as it goes downward.

Therefore, when the rainwater falling through the flow path passes through the filter member 15, it takes a long time to pass through the filter member 15 because of the double wall structure. Therefore, the rainwater initially supplied passes through the filter member 15 And falls immediately, is discharged through the discharge pipe (11), and rainwater supplied after the initial stage is allowed to pass through the filter member (15).

As a result, the initial rainwater containing a large amount of foreign matter is filtered without being filtered by the filter member 15, and only rainwater supplied later, which contains a relatively small amount of foreign matter, is filtered during the passage through the filter member 15, Filtered water can be obtained.

The filter member 15 may be supported and fixed by supporter members 41 and 43 provided on the inner side of the intermediate housing 9.

The supporter members 41 and 43 include a first supporter 41 protruding upward from the rim of the intake plate 42 and formed along the circumferential direction; And a second supporter 43 protruding from the upper surface of the first supporter 41 and formed along the circumferential direction to support the lower portion of the filter member 15.

The first supporter 41 has a double structure in which an insertion groove h1 is formed by overlapping plate members, and the lower portion of the insertion groove h1 has an open shape. The second supporter 43 has a shape in which a single plate is wound into a cylindrical shape.

Accordingly, when the filter member 15 is fixed by the supporter members 41 and 43, the filter member 15 is disposed in the middle of the intermediate housing 9 so that the upper portion communicates with the first through hole, And communicates with the second through hole.

The rainwater falling down from the upper housing 5 drops down to the inside of the filter member 15 through the first through hole 19 and is discharged to the lower housing 13 through the second through hole 44 again.

In this process, the foreign matter can be filtered by the rainwater passing through the filter member 15 in the lateral direction.

A third flange f3 protrudes from the lower outer circumferential surface of the intermediate housing 9. The flange f3 abuts against the fourth flange f4 protruding from the outer circumferential surface of the lower housing 13, And can be fixed to the lower housing 13.

Since the intermediate housing 9 and the lower housing 13 are independent from each other and are coupled by the third and fourth flanges f3 and f4, the filtered water outflow pipe 7 or the discharge pipe 11, The intermediate housing 9 or the lower housing 13 can be appropriately rotated to avoid this interference with the external obstacle.

At this time, since a plurality of long holes are formed on the fourth flange f4, the intermediate housing 9 or the lower housing 13 can be fixed at an arbitrary position by appropriately rotating the bolts and then fastening the bolts.

The lower housing 13 has a cylindrical shape similar to the upper and lower housings 13, and the discharge tube 11 is connected to the inside thereof. Therefore, the rainwater dropped through the second through-hole 44 can be discharged to the outside of the rainwater filter 1 through the discharge pipe 11. [

The inlet formed at the upper portion of the discharge tube 11 may be fixed by being inserted into the insertion groove h1 of the first support 41 disposed at the rim of the second through hole 44. [

An outlet formed at one lower end of the discharge tube 11 protrudes from the outer circumferential surface of the lower housing 13.

Therefore, the rainwater falling from the intermediate housing 9 can be discharged to the outside through the discharge pipe 11. [

A fifth flange 47 is disposed at the inlet of the inlet pipe 3 and a sixth flange 49 is disposed at the outlet of the filtered water outlet pipe 7. A seventh flange 51) are arranged so that the pipes can be connected to the flanges 47, 49, 51.

At this time, the angles of the fifth to seventh flanges 47, 49, 51 are inclined at a certain angle instead of vertical, so that the inflow and outflow of rainwater can be facilitated.

In other words, the fifth flange 47 is arranged to be inclined toward the rainwater filter 1 around the vertical line, so that the pipe connected to the fifth flange 47 is also inclined so that the direction of the rainwater filter 1 is lowered.

Therefore, the rainwater supplied to the rainwater filter 1 through the inflow pipe 3 can flow by gravity along the inclined pipe, so that it can flow smoothly without any additional power such as a pump.

The sixth flange 49 also has a shape inclined in the direction away from the rainwater filter 1 around the vertical line. That is, in the same direction as the sixth flange 49.

As the sixth flange 49 is inclined in the opposite direction to the rainwater filter 1, the pipe connected to the sixth flange 49 is also inclined downward in the direction opposite to the direction of the rainwater filter 1.

Accordingly, the rainwater discharged through the filtered water outlet pipe 7 can flow by gravity along the inclined pipe, and can flow smoothly without any additional power such as a pump.

The seventh flange 51 also has a shape tilted away from the rainwater filter 1 about a vertical line. In other words, it is inclined in the direction opposite to the seventh flange 51.

As the seventh flange 51 is tilted in the opposite direction in the rainwater filter 1, the pipe connected to the seventh flange 51 is also inclined so that it becomes lower toward the opposite direction of the rainwater filter 1.

Therefore, the rainwater discharged through the discharge pipe 11 can flow by gravity along the inclined pipe, and can flow smoothly without any additional power such as a pump.

As described above, since the fifth to seventh flanges 47, 49 and 51 are inclined at different angles to each other, the rainwater flows into the rainwater filter 1 and coincides with the discharge direction The rainwater passes through the rainwater filter 1 more effectively and is filtered by the filter member 15 in this process, so that the filtered water of good quality can be obtained.

10 and 11 illustrate another embodiment of the present invention. In this embodiment, an extension pipe 50 is additionally provided on the upper portion of the upper housing 5.

That is, the extension pipe 50 can be installed upright by fixing the intermediate ring 52 on the upper portion of the upper housing 5 and inserting the lower portion of the extension pipe 50 inside the intermediate ring 52.

At this time, the extension pipe 50 can be stably fixed in an upright state by being fastened to the lower portion of the extension pipe 50 through the bolt 54 such as an eye bolt from the outside of the intermediate ring 52.

The extension pipe 50 has a tubular shape with upper and lower openings, and is formed at a constant height. Therefore, when the height of the strainer is insufficient when the strainer is installed, the height of the strainer can be adjusted by further mounting the extension tube 50.

An upper ring 56 is fixed to the upper end of the extension pipe 50 by a bolt 58 or the like and a cover 60 is coupled to an upper portion of the upper ring 56.

At this time, a projecting step 62 is formed on the bottom surface of the cover 60 along the circumferential rim, and the circular protruding step 62 is inserted into the upper part of the upper ring 56. Accordingly, the cover 60 is seated on the upper portion of the upper ring 56, thereby sealing the upper opening of the extension pipe 50.

The structure of the cover 60 is similar to that of the cover 60 shown in Fig. 2, and the handle 64 is mounted on the top of the cover 60. Fig. Thus, the operator can raise or lower the cover 60 by means of the handle 64.
