First, a chamber part 100 is provided as a body of a filtration device for filtering foreign matters from water.

The chamber part 100 is provided with a first entrance 110, a second entrance 120 and a third entrance 130. The first entrance 110, the second entrance 120, the third entrance 130, A first valve 111, a second valve 121 and a third valve 131 are provided in each of the first,

The chamber 100 is provided with a first flow wall 140 for spreading the water introduced from the first entrance 110 and a second entrance 120 formed inside the chamber 100, And a second flow wall 150 for collecting the outflowed water as a whole.

The upper end of the fiber filter unit 200 is fixed to the upper part of the inside of the chamber and the lower end of the fiber filter unit 200 is fixed to the upper part of the up / . The overall arrangement of the fiber filter unit 200 is arranged in the form of a hollow tube that surrounds the main surface of the cylindrical body 500, which will be described later, that is, a circle.

The upper and lower portions of the upper and lower portions of the upper and lower portions of the fiber bundle portion 200 are respectively provided with a plurality of holes 310 through which filtered water and backwash water flows in and out, .

The upper and lower eastern portions 300 have a weight enough to sink even in the water, so that the fibrous filter portion 200 is pulled downward by the force of the upper and lower eastern portions 300 sinking, Thereby forming a filtration gap capable of filtration.

On the other hand, the upward and downward moving parts 300 move upward by buoyancy opposite to gravity such as hydraulic pressure transmitted from below.

The upward movement of the upper and the lower eastern portion 300 causes the fiber filter portion 200 to relax so that the fiber filter portion 200 forms a cleaning gap through which the foreign matter can be washed by the flowing water.

The buoyancy driving unit 400 is provided to supply the moving force to the vertically moving part 300 as described above. Specifically, the buoyancy driving part 400 has a function of communicating the upper part with the hole 310 and a lower part communicating with the third doorway 130 to move the upward and downward moving part 300 upward through the reverse water pressure water pressure do.

For the above function, the buoyancy driving unit 400 includes a first flow pipe 410, a second flow pipe 420, and a cylinder 430.

The first flow pipe 410 is a main passage through which the backwash water is discharged at a constant water pressure through the central portion of the upper and lower moving parts 300. The second flow pipe 420 is provided with a through hole 300) to serve as a sub-passage for allowing filtered water and backwash water to flow in and out. Accordingly, the water pressure of the reverse water is transferred to the upper and lower eastern parts 400 through the first and second flow path pipes 410 and 420.

The cylinder 430 includes a cylinder body 431 and a cover 432 for the air hole. The cylinder body 431 is disposed inside the first flow pipe 410 and is formed to be lifted by water pressure of the reverse flow water, and is vertically movable along the first flow pipe 410. At this time, a rising guide groove 431b is formed at the lower end of the cylinder body 430 so as to gradually taper upward, so that the rising efficiency of the cylinder 430 due to the water pressure of the reverse water flowing out from the third doorway 130 is further increased, 431 can be prevented from being damaged without being able to withstand the water pressure.

The hole 432 is provided on the upper portion of the cylinder body 431 so as to close the upper portion of the cylinder body 431 to block the hole 310 formed in the center of the upper and lower moving parts 300 when the cylinder 430 is moved upward. And has a role of guiding the upper and lower hoists 300 to rise.

That is, when the backwash water is supplied, the cylinder 430 is moved upward by the water pressure to block the hole 310 located at the center of the upper part 300, and when the air supply is stopped, ).

Finally, a cylindrical body 500 in which a plurality of porous tubes 510 are formed may be provided in the chamber part 100. The cylindrical body 500 further increases the filtration rate of the raw water from the holes 310 of the upper and lower moving parts 300 by filtering the filtered water filtered through the fiber filter part 200 through the pore tube 510 It is possible. Also, when the fibrous filter member 200 is loosened, it can also serve as a support for preventing the upward / downward movement of the up / down moving part 300 from being separated from the buoyancy driving part 400.

Hereinafter, the operation of the present embodiment will be described with reference to Figs. 2 and 3. Fig.

2, first, the fiber filter unit 200 is pulled down by the sinking force of the up-and-down moving unit 300, so that the fiber filter unit 200 forms a filtration gap for filtering foreign matter .

Then, the raw water flows into the first entrance 110 and passes through the fiber filter unit 200, so that the foreign matter is filtered. Thereafter, a secondary filtration process is performed through the porous pipe 510 of the cylindrical body 500 to connect the upper and lower openings 310 and 310 of the vertically moving part 300 provided under the cylindrical body 500 And then finally discharged to the third entrance 130. In this case,

If the filter is used for a long time in the state of FIG. 2, the amount of foreign matter accumulated in the fiber filter unit 200 increases, and the filtration performance of the fiber filter unit deteriorates.

Therefore, it is necessary to change the state of FIG. 3 from time to time to clean the fiber filter portion 200.

3, backwash water is supplied from the third entrance 130. The supplied reverse osmosis water is moved to the lower side of the upper and lower moving parts 300 through the first flow pipe 410 and the second flow pipe 420 of the buoyancy driving part 400, 300, respectively.

The cylinder 430 having received the water pressure moves upward and blocks the hole 310 at the center of the upper and lower moving parts 300 through the hole 432 for closing the upper part of the cylinder 430, Up.

By the above-described process, the upper and lower hair extensions 300 are pulled upward, and the pulling force of the fiber filter unit 200 is relaxed. That is, the fiber filter unit 200 forms a cleaning gap so that the foreign matter can be cleaned, and the fiber filter unit 200 can be cleaned by the flowing water.

In detail, the backwash water flowing into the third entrance 130 sequentially passes through the upper and lower eastern parts 300 and the cylindrical body 500, and finally passes through the fiber filter part 200, And is then discharged to the second entrance 120. [

Particularly, the water sprayed toward the fiber filter unit 200 through the multi-tube pipe 310 formed in the cylindrical body 300 is separated from the fiber filter unit 200 so that the foreign substances accumulated in the fiber filter unit 200 can be easily separated. .

When backwashing of the fiber filter unit 200 is completed, the supply of backwash water to the third entrance 130 through the third valve 131 is stopped.

The supply of the washing water is stopped and the cylinder 430 is moved to the lower part and the water flows into the buoyancy chamber through the hole 310 so that the upper and lower parts 300 are submerged, Thereby forming voids.

As described above, in the present embodiment, in order to convert the air gap of the fiber filter unit 200, the upper and lower edges 300 are lifted or settled by supplying and stopping reverse water without a separate driving unit, It can be converted into a cleaning supply and filtration pore.

In order to increase the weight of the upper and lower moving parts 300, a weight can be added to the upper and lower moving parts 300. In addition, the volume of the space portion formed in the upper and lower eastern portions 300 can be increased or decreased as needed.

&Lt; Embodiment 2 >

An embodiment according to the present invention will be described with reference to Figs. 5 and 7. Fig.

5 and 7 are conceptual views of a longitudinal section of an embodiment according to the present invention. Specifically, FIG. 5 shows a state in which a filtration gap is formed in a fiber filter material, and FIG. 7 shows a state in which a fiber filter material forms a cleaning gap.

In the interior of the chamber part 100, the upper and lower parts of the upper and lower parts are fixed. At this time, a passage hole 161 for introducing the filtered water to the third entrance 130 is formed at the center of the filter unit 160, and a cylindrical body 500 is provided in the passage hole 161.

Specifically, the cylindrical body 500 is a cylindrical body whose upper portion is open and whose lower portion is closed, and a plurality of porous tubes 510 are formed on a main surface thereof. The upper part of the cylindrical body 500 is fixed to the female part repairing part 160 so that the inside of the cylindrical body 500 is in communication with the through hole 161 of the female part repairing part 160. [ In addition, the cylindrical body 500 can further increase the filtration rate of the raw water by filtering the filtered water filtered through the fiber filter unit 200 through the porous tube 510 by the second order. Also, when the fibrous filter member 200 is loosened, it can also serve as a support for preventing the upward / downward movement of the up / down moving part 300 from being separated from the buoyancy driving part 400.

The upper end of the fiber filter unit 200 is fixed to the upper part of the inside of the chamber and the lower end of the fiber filter unit 200 is fixed to the upper part of the up / . Further, the overall arrangement of the fiber filter media 200 is arranged in the form of a hollow tube that surrounds the main surface of the cylindrical body 500, that is, a circle.

The upper and lower portions of the upper and lower portions of the upper and lower portions are formed with holes 310 through which filtered water and air flow in and out, respectively, .

When the upward and downward moving parts 300 are filled with air, the buoyancy chambers 320 for moving the up and down moving parts 300 upward by buoyancy may be formed. The buoyancy chamber 320 means a space in which the air can be confined once the air is filled. That is, in the present invention, the buoyancy chamber 320 has a shape similar to that of reversing the rice bowl, and it is needless to say that various forms of the buoyancy chamber 320 can be manufactured as needed.

As the upper and lower moving parts 300 move upward as air is filled in the buoyancy chamber 320, the fiber filter media 200 is relaxed and the loosened fiber filter media 200 can be cleaned Thereby forming a cleaning gap. The buoyancy driving unit 400 and the wind generating unit 600 are provided to supply air to the buoyancy chamber 210 of the up / down moving unit 300 as described above.

Meanwhile, the air supplied to the buoyancy chamber 320 of the upper and the lower eastern portion 300 should be discharged to the outside and the buoyancy chamber 320 filled with water to form a filtration gap again. For this purpose, a hole 310 is also formed in the upper part of the upper and lower parts 300 for discharging the air in the buoyancy chamber 320 and filling the water. The hole 310 provided in the upper portion of the upper and lower shovel 300 communicates with the buoyancy chamber 320 to fill the buoyancy chamber 320 with water and the air in the buoyancy chamber 320 flows through the hole 310 And is discharged to the outside.

In addition, a plurality of air injection holes 340 through which air is injected toward the fiber filter media 200 can be formed in the upper and lower eastern parts 300, and air supplied to the buoyancy chambers 320 can be injected into the air injection holes 340, An air guide passage 330 may be provided to guide the air to be discharged. At this time, the lower part of the air guide passage 330 is provided higher than the lower part of the up-and-down moving part 300, so that the air in the buoyancy chamber 320 can be prevented from escaping to the outside of the up-and-down moving part 300.

The upper part of the wind generating part 600 communicates with the raw milk inflow inlet controlled by the third valve 131 and the lower part of the wind generating part 600 is arranged to communicate with the third entrance 130, Generating member.

The wind generating unit 600 includes a housing 610, an impeller 620, a first rotating shaft 630, a first propeller 640, and an air supply pipe 650.

The housing 610 has an upper portion communicating with the raw milk inlet and a lower portion communicating with the third outlet 130 to accommodate the members therein so that the remaining members of the wind generating portion 600 can perform their respective functions At this time, the members may be partitioned to partition each other so that mutual interference does not occur. Also, although the size and shape of the housing 610 are shown in a predetermined form according to FIGS. 5 and 7, the housing 610 can be variously modified in various ways depending on how the members accommodated therein are accommodated.

The impeller 620 is accommodated in the lowermost portion of the housing 610 and rotates by the water flow introduced through the raw milk inlet and rotates through a first rotation shaft 630 which is axially coupled with the impeller 620, And functions as a motor that transfers energy to other members.

5, a lower portion of the housing in which the impeller is accommodated may be formed with a pair of through-holes facing each other on the circumferential surface, and an induction channel communicating with the through-hole may be formed along the circumferential surface .

In addition, the induction water channel may be formed with a raw milk inflow inlet through which backwash water flows in the tangential direction of the peripheral surface, a partition wall partitioning the internal space in the flow direction in the raw milk inflow, and an inner water channel and an outer water channel by the partition wall .

In the induction waterway configured as described above, the inner waterway communicates with one through-hole adjacent to the inlet, allowing the backwash water, which has been introduced through the raw milk-inflowing inlet, to flow into the one through-hole, and the outer waterway extends along the circumference of the housing, So that the backwash water flows into the other through-hole.

That is, the reverse segregation is divided into bifurcations by the partition walls, and then flows into the interior of the housing through a pair of through-holes. At this time, each of the incoming reverse osmosis water forms a pair of vortices and flows from the upper part to the lower part. This pair of vortices balances to a very similar intensity and prevents the backwash water flowing into the housing from overflowing to the outside.

Here, the width of the third entrance 130 through which the backwash water is to be discharged is desirable to increase the rotation speed of the impeller 620 due to the rapid vortex. Specifically, the width of the third entrance 130 is larger than the width of the entrance It is possible to maintain the rotational speed of the impeller 620 at an appropriate speed or more.

The first propeller 640 accommodated in the upper portion of the housing 610 generates wind as it rotates in conjunction with the rotation of the first rotary shaft 630. Specifically, the first rotation shaft 630 is provided with a first gear 631 whose center is coupled to the first rotation shaft 630. The diameter of the first propeller 640 is greater than the diameter of the first gear 631 And a second gear 641 formed to be short and coupled to the center shaft of the first propeller 640 is provided.

The first rotation shaft 630 further includes a gear 632 for transmitting rotational energy to a second gear 641 engaged with the other side through one side that rotates in engagement with the first gear 631, The first propeller 640 is rotated at a higher speed than the impeller 620 during the rotation of the impeller 620 due to the engagement of the first gear 631, the transmission gear 632 and the second gear 641. [ So that air is generated.

Finally, the air supply pipe 650 connects the housing 610 and the buoyancy drive unit 400 so as to communicate the wind generated from the first propeller 640 with the buoyancy drive unit 400, that is, the first flow pipe 410, As shown in Fig.

5 and 7, a valve for controlling air supply may be further installed in the air supply pipe 650, and air may be supplied to the buoyancy driving unit 400 when the raw water is filtered through the valve .

The buoyancy driving part 400 moves the upward and downward moving part 300 upward through the air provided from the wind generating part 600 and includes a first flow pipe 410 and a cylinder 430 for this purpose.

The first flow pipe 410 is a passage that passes through the hole 310 provided in the lower part of the upper and lower moving parts 300. The lower portion of the first flow pipe 410 communicates with the lower portion of the air supply pipe 650 which is a path through which the wind generated from the first propeller 640 is moved, .

The cylinder 430 includes a cylinder body 431 and a cover 432 for the air hole. The cylinder body 431 is disposed inside the first flow pipe 410 and is raised by the air supplied through the air supply pipe 650 and is movable up and down along the first flow pipe 410 .

That is, when the backwash water is supplied, the cylinder 430 moves upward by the buoyant force to block the hole 310 located at the center of the upper and lower moving parts 300. When the air supply is stopped, the cylinder 430 moves downward, (310).

Finally, the auxiliary washing unit 700 is provided in the cylindrical body 500, and the auxiliary washing unit is provided to more efficiently perform the washing of the fiber filter material when the fiber filter unit 200 forms backwashing gaps Member.

To this end, the auxiliary washing unit 700 includes a second rotating shaft 710 and a plurality of second propellers 720. The upper end of the second rotary shaft 710 is connected to the lower end of the first rotary shaft 630 of the wind generating part 600 and extends a predetermined length downward through the through hole, To 5 cm apart. The second propeller 720 is axially coupled to the second rotary shaft 710 at a predetermined interval to generate rotating water flow by rotation. The respective rotating water streams generated by the plurality of second propellers pass directly through the porous pipe 510 of the cylindrical body 500 and are transmitted to the fiber filter unit 200. The water pressure generated along the rotating water flows So that the foreign substances accumulated in the fiber filter unit 200 are separated from the fiber filter unit 200.

Hereinafter, the operation of the present embodiment will be described with reference to FIGS. 5 and 7. FIG.

In FIG. 5, the fiber filter unit 200 is pulled down by the sinking force of the up-and-down moving unit 300. When the upper and lower eastern portions 300 are completely sunk, the fiber filter portion 200 forms a filtration gap for filtering the foreign matter.

Next, the raw water for filtration flows into the first inlet 110 and then passes through the fiber filter media 200 to pass the foreign material through the porous pipe 510 of the cylindrical body 500, And is discharged to the entrance 130, thereby completing all the filtration processes.

At this time, if the filter is used for a long time in the state of FIG. 5, the amount of foreign matter accumulated in the fiber filter media 200 increases, which leads to a decrease in filtration performance. In order to prevent this, it is preferable to change the state of FIG. 7 from time to time to clean the fiber filter media 200.

7, the backwash water passes through the raw water inlet and enters the interior of the chamber part 100 through the third doorway. At the same time, air is supplied from the wind generating part 600 to the buoyancy driving part 400 The buoyancy chamber 320 is filled with air.

That is, the air flows through the first flow pipe 410 and the upward guide groove 431b of the cylinder 430 to fill the buoyancy chamber 320.

At this time, the cylinder 430 is moved upward by the pressure of the air to block the hole 310 provided in the upper part of the upper and lower movable part 200.

The air supplied to the buoyancy chamber 320 first completely fills the buoyancy chamber 320 and then is guided along the air guide passage 330 and then flows toward the fiber filter portion 200 through the air injection hole 340 . Of course, in this process, the buoyancy chamber 320 maintains a state of being filled with air.

When the buoyancy chamber 320 is filled with air, the upward and downward moving parts 300 float up due to the buoyancy force, and the fiber filter part 200 is released from the downward force and relaxed. That is, the fiber filter unit 200 forms a cleaning gap so that the foreign matter can be cleaned.

As the washing clearance is formed, the backwash water flowing into the third entrance 130 flows through the fiber filter unit 200 through the pores 510 of the cylindrical body 500, and the fiber filter unit 200 is backwashed And finally discharged to the second entrance 120.

At this time, the air injected through the air injection hole 340 blows the fiber filter unit 200 so that the foreign matter accumulated in the fiber filter unit 200 is more easily dislodged. A plurality of second propellers 720 provided in the second rotary shaft 710 of the auxiliary cleaning part 700 are connected to the impeller 620 through the first rotary shaft 630 in the cylindrical body 500 Rotate. A plurality of water streams passing through the pore tube 510 are generated in the cylindrical body 500 as the rotation continues and the water streams passing through the pore tube 510 directly collide with the fiber filter media 200, Thereby guiding the accumulated foreign substances to be separated.

When the backwashing of the fiber filter unit 200 is completed through the above-described process, the third valve 131 is closed and the air supply of the wind generating unit 600 is also stopped accordingly.

As a result, the cylinder 430 descends to the bottom and the holes 310 formed in the upper part of the upper and lower moving parts 300, which are blocked by the cylinder 430, are reopened through which the external water replenishes the buoyancy chamber 320, And the air in the second chamber 320 is discharged to the outside.

As the buoyancy chamber 320 is filled with water, the high porosity portion 300 is submerged so that the fiber filter portion 200 forms a filtration gap again.

FIGS. 8 and 9 are conceptual views of the longitudinal section of the third embodiment of the present invention. Specifically, FIG. 8 shows a state in which the fiber filter media forms a filtration gap, and FIG. 9 shows a state in which a fiber filter media forms a cleaning gap .

The third embodiment is basically the same as the second embodiment except that the auxiliary supporting part 800 may be further provided to smoothly form the gap formed in the fiber filter material part .

The auxiliary support unit 800 functions to guide the filtration and backwashing process, which progresses in the formation of the voids in the fiber filter unit, smoothly. For this purpose, the auxiliary support unit 800 includes the upstream and downstream shafts 810 and the connection pins 820 .

First, the upper and lower shovel bars 810 are used to filter foreign substances contained in water. The shovel bar 810 is shaped like a bar extending up and down, And the lower end thereof is fixed to the upper portion of the upper and lower moving parts 300. [ In addition, the overall arrangement of the upper and lower shoehorns 820 is arranged in the form of a hollow tube that surrounds the outer side of the fiber filter media 200, that is, a circle having the same shape as that of the fiber filter media 200.

One side of the connecting pin 820 is hinged to the upper and lower shafts 810 and the other side is hinged to the fiber filter unit 200.
