In general, filtration is a representative process for removing contaminants present in water in a water purification process for producing living water and industrial water and a water treatment process for treating sewage and wastewater. For example, in a water purification plant, chemicals that coagulate contaminants are mixed and stirred with raw water to form contaminants such as phosphate contained in raw water in the form of solids, which are transferred to a sedimentation tank, where they undergo a sedimentation process, and through a filtration process in a sand filter paper. The final purified water is used as drinking water.

In addition, in the case of sewage and wastewater treatment plants, water that has undergone biological treatment and chemical treatment is usually sent to a sand filter, but the filter layer is easily clogged with contaminants, and as a result, the filtration efficiency is significantly lowered, so the contamination remaining in the filter layer. Backwashing is necessary to remove the material.

Therefore, in recent years, there is a growing demand for a filtering device capable of effectively performing backwashing, which is a process of removing foreign substances collected in the filtering process, while increasing the filtering efficiency by increasing the filtering speed.

It is provided to completely inform the person who has the scope of the invention, and the present invention is only defined by the scope of the claims.

In addition, in the description of the present invention, if it is determined that related known technologies may obscure the gist of the present invention, a detailed description thereof will be omitted.

1 is a flowchart illustrating a water treatment filtration and backwashing method according to an embodiment of the present invention.

Referring to FIG. 1 , in the water treatment filtration and backwashing method (S10) according to an embodiment of the present invention, it is possible to generate backwash water to improve backwash efficiency, to purify sewage water, and to purify the sewage water. Separation and discharge of the purified water may be possible by forming a discharge port differently according to the specific gravity of foreign substances in the purified water including the foreign substances contained therein.

Through this, it is possible to use purified water suitable for the purpose of use, improve the operation efficiency of the filtering device, and increase the washing efficiency of the filtering material to extend the life of the filtering material, the filtering unit installation step (S100), the sewage inflow step (S200), the first purification step (S300) and the first purified water separation step (S400) may be performed to discharge the purified water.

The filtering unit installation step (S100) may be a step of installing the filtering device 10. In the filtering unit installation step (S100), a plurality of filtering layers 330 including filter media M are rotated and stacked, and a rotating unit 200 having a magnetic force generating unit 250 installed therein is installed in the center, thereby rotating the rotating unit. Through (200), the center of the filtering layer (330) coincides, and rotation of the filtering unit (300) may be possible according to the rotation of the rotation unit (200). At this time, the detailed configuration of the filtering device 10 will be described later. Thereafter, after installing the filtering device 10, the sewage inflow step (S200) may be performed.

In the sewage inflow step (S200), sewage may be introduced into each filter layer 330 of the filter device 10 in which the filter layer 330 is stacked. At this time, the inflow of sewage may be introduced in a state where the through-hole 331a formed inside the filtering unit 300 and the inlet 250a formed on the rotating unit 200 do not match.

That is, a position where the first rotational groove 331b formed in the filtering unit 300 including the stacked filtering layer 330 and the first rotation coupling member 230 protruding from the outer surface of the rotational unit 200 are not engaged. sewage may enter.

In addition, the wing portion 370 may be in close contact with the outer surface of the filter portion 350 to allow sewage to flow in in a sealed state.

Through this, when sewage flows into the pipe, the sewage can be prevented from being injected into the filter layer 330 and discharged to the outside.

Thereafter, when sewage is introduced, a first purification step (S300) may be performed so that the first purification of the sewage may be performed by the filter medium M.

In the first purification step (S300), the first purification water may be generated by purifying the sewage water in a state in which the rotation is stopped. Thereafter, in a state in which the primary purified water is generated, the rotating unit 200 and the filtering unit 300 may be coupled by the coupling of the rotating unit 200 .

For example, after a certain period of time has elapsed so that the primary purified water is generated, the rotating part 200 is rotated and the first rotating groove 331b and the first rotating coupling member 230 are moved to a matching position and coupled to each other, so that the rotating part ( 200) and the filtering unit 300 may be combined.

Thereafter, the filtering unit 300 is rotatable according to the rotation of the rotating unit 200 to perform the first purified water separation step (S400).

In the first purified water separation step (S400), when the filtering unit 300 rotates according to the rotation of the rotating unit 200, the primary purified water having a high specific gravity of foreign substances can be moved outward by the rotation, and the foreign substances The primary purified water may be rotated so that the primary purified water having a low specific gravity can be moved inward.

Through this, the primary purified water moving in the outward direction can be discharged and the primary purified water moving inward can be discharged to the outside through the rotation unit 200 located inside.

Thereafter, the primary purified water moving outward may perform a filtering step (S500).

In the filtering step (S500), when a part of the primary purified water containing a high specific gravity of the primary purified water is moved outward by the rotating unit of the rotating unit 200, the filter unit 350 is moved outward. It is possible to generate secondary purified water by secondary filtering of primary purified water.

Thereafter, the filtered secondary purified water is discharged to the lower side of the wing unit 370 by disposing the wing unit 370 away from the filter unit 350 and moving downward by colliding with the inner surface of the wing unit 370. A possible first discharge step (S600) may be performed.

medial

In addition, when a part of the primary purified water containing foreign substances with a low specific gravity among the primary purified water moving inward is moved inward, the primary purified water flows into the rotating part 200 and the primary purified water is discharged downward. A second discharge step (S700) may be performed.

At this time, the primary purified water containing foreign substances with a low specific gravity may have a higher degree of purification than the primary purified water containing foreign substances with a high specific gravity moving outward, so that the primary purified water discharged in the second discharge step (S700) The purified water may be subjected to a later step for producing drinking water or the like.

In addition, primary purified water moving inward can be used as backwash water. At this time, in order to use the backwash water, a backwash water generating step (S830) of generating magnetized water by applying magnetic force to the primary purified water flowing into the rotating unit 200 to ionize the primary purified water may be performed. At this time, the magnetized water is ionized purified water, and the efficiency of backwashing may be higher than that of general purified water.

At this time, in order to generate backwash water by magnetizing the first purified water flowing into the flow path 255a inside the rotating part 200, the first purified water introduction step (S8100), the magnetized water generation step (S820) and the backwash step (S830) are performed. can be performed.

The first purified water introduction step (S810) may be a step in which the through hole 331a and the inlet 250a are matched and the first purified water introduced inside by the rotational force flows into the flow path 255a of the rotation unit 200.

Thereafter, a magnetized water generation step of ionizing the first purified water passing through the passage 255a by driving the first magnetic body 251 and the second magnetic body 253 having different polarities installed outside and inside the passage 255a (S820). ) can be performed.

After the magnetized water generation step (S820) is performed, a pipe through which sewage is introduced is connected to a portion discharged downward from the rotation unit 200, and backwash water, which is magnetized water, is introduced into the pipe through which the sewage is introduced through a pump to flow into the filter unit. Magnetized water may be introduced into the interior of the 300 .

Thereafter, the first discharge step (S600) and the second discharge step (S700) can be continuously performed, so that the inside of the filtering unit 300 can be continuously washed.

At this time, the second magnetized water discharged in the second discharge step (S700) and discharged to the outside through the first discharge step (S600) is added to the magnetized water and introduced into the pipe during the backwash step (830) to obtain purified water. Since it can be used continuously, it is possible to reduce the fluid required for performing backwashing, thereby improving cost and time efficiency.

Referring to FIGS. 2 and 3, in the water treatment filtration and backwashing method 10 according to an embodiment of the present invention, sewage is injected into the inside through various routes, and the injected sewage can be purified over time. there is.

In addition, the purified water, which has been partially purified after a certain period of time, can be separated by gravity according to the rotation of the water treatment filtration and backwashing method 10, so that the purified water containing a relatively large number of foreign substances in the purified water can be subjected to water treatment filtration and backwashing method 10 Purified water with a relatively high degree of purification, which is discharged along the outer surface of the purified water and contains relatively few foreign substances, can be discharged from the center. Therefore, the discharge path of the purified water is different according to the specific gravity of foreign substances in the purified water that contains some foreign substances. It may include a cover part 100, a rotating part 200, and a filtering part 300 so that purified water suitable for the purpose can be used.

The cover part 100 is connected to the upper and lower ends of the stacked filtering parts 300 to prevent the separation of the filtering part 300, and to improve the sealing power of the upper and lower parts of the filtering part 300, so that water treatment filtration and To enhance the durability of the backwashing method 10, an upper cover 110 and a lower cover 130 may be included.

The upper cover 110 may be formed in a circular cross section. In addition, the upper cover 110 may be formed of a material having greater durability than the durability of the magnetic force generating unit 250 and the filtering unit 300.

In addition, a circular hole may be formed in the center of the upper cover 110 . At this time, the hole formed in the center may be formed in a shape corresponding to the hole formed in the center of the filtering unit 300 to be described later, and the rotation unit 200 to be described later may be coupled.

In addition, the upper cover 110 can be combined with the filtration layer 330 located at the top of the filtration unit 300, so that the upper end of the filtration unit 300 can be sealed to prevent sewage or purified water from escaping to the top. there is.

The lower cover 130 may be formed in a circular cross section. In addition, the lower cover 130 may be formed of a material having greater durability than the durability of the magnetic force generating unit 250 and the filtering unit 300. That is, it may be formed of the same material as the upper cover 110.

In addition, a circular hole may be formed in the center of the lower cover 130 . At this time, the hole formed in the center may be formed in a shape corresponding to the hole formed in the center of the filtering unit 300 to be described later, and the rotation unit 200 to be described later may be coupled.

That is, it is formed in a shape corresponding to the hole formed in the center of the above-described upper cover 110 and a straight line, so that the rotating part 200 can pass through.

In addition, the lower cover 130 may be combined with the filtration layer 330 located at the lowermost end of the filtration unit 300 to seal the lower end of the filtration unit 300 to prevent sewage or purified water from escaping to the top. there is.

In addition, the inner surface formed in the direction toward the hole of the center of the upper cover 110 and the lower cover 130 can be sealed, so that the purified water or sewage moved in the rotation unit 200 is removed from the upper cover 110 and the lower cover. It is possible to prevent outflow toward the inner direction of (130).

At this time, while penetrating the center of the upper cover 110 and the lower cover 130 and the filtering unit 300, the rotation unit 200 may be penetrated and coupled.

Figure 4 is a perspective view of a magnetic force generation according to an embodiment of the present invention, Figure 5 is a view showing a rotation unit installed inside the filtering unit according to an embodiment of the present invention, Figures 6a and 6b are one embodiment of the present invention A plane cross-sectional view of the rotation unit according to the example, and FIG. 7 is a front view of the rotation unit according to an embodiment of the present invention.

2 to 7, the rotation unit 200 according to an embodiment of the present invention may be installed through the upper cover 110 and the lower cover 130, and the upper cover 110 and the lower cover ( 130) may be coupled while penetrating the filtering unit 300 stacked between them.

Also, the rotation unit 200 may be formed in a cylindrical shape. At this time, the rotating unit 200 may generate magnetic force therein, and is coupled while penetrating the plurality of stacked filtering units 300, and the coupling force with the filtering unit 300 is strengthened by the rotation of the rotating unit 200. and may include a magnetic body 210, a first rotation coupling member 230, and a magnetic force generating unit 250 so that a flow path 255a is formed therein to discharge purified water downward.

The magnetic body 210 may be formed in a cylindrical shape. In addition, since the magnetic body 210 may have a flow path 255a formed therein, purified water purified by the filtering unit 300 to be described later may be introduced.

At this time, the passage 255a may be formed by cutting so that a space may be formed therein in a state in which the inside of the magnetic body 210 is molded.

In addition, the outer surface of the magnetic body 210 may be divided into a plurality of layers. For example, the magnetic body 210 may be formed of first to sixth magnetic bodies 211 , 212 , 213 , 214 , 215 , and 216 . At this time, the layer of the magnetic body 210 may be formed at a position corresponding to each filtering layer 330 .

For example, the outer surface of the first magnetic body 210 may be formed at a position where the first filtering layer 330 is coupled, so that the purified water filtered by the first filtering layer 330 may be formed on the first magnetic body 210. ) can be introduced into the interior of

In addition, a pair of inlets 250a formed in the magnetic force generating unit 250 may be formed to extend on the outer surface of the magnetic body 210 . At this time, the inlet 250a may be connected to the flow path 255a formed inside the magnetic body 210 .

In addition, in the inlet 250a, the purified water purified inside the filtering unit 300 is moved to the inside of the magnetic body 210 through a hole extending from the inlet 250a formed in the magnetic force generating unit 250, (210) Purified water may flow into the inside.

At this time, an extension body (not shown) of the magnetic body 210 is formed at the bottom of the sixth magnetic body 210 located at the bottom, and both sides of the extension body extended at the lower end of the magnetic body 210 are opened , Purified water flowing into the magnetic body 210 may be extended to the lower end of the magnetic body 210 and discharged to both sides of the extension body connected to the drive unit D.

For example, when the sewage introduced into the filtering unit 300 is purified, the purified water, which is the purified sewage, may be introduced into the magnetic body 210 . At this time, when the flow path 255a formed on the inside of the magnetic body 210 and the inlet 250a formed on the outer surface of the magnetic body 210 are aligned by rotating the magnetic body 210, the purified water flows through the magnetic body 210. ) can be introduced into the inside of the

In addition, by mismatching the inlet 250a and the flow path 255a, the purified water in the filtering unit 300 can be prevented from flowing into the magnetic body 210, so that sewage is located inside the filtering unit 300. Purification can be achieved by means of a filter medium.

That is, the magnetic body 210 may be rotatable separately from the filtering unit 300, and the first rotation coupling member 230 of the magnetic body 210 is formed in the first rotational groove 331b formed in the filtering unit 300. While being caught, by being fixed to the filtering unit 300, it may be rotatable at the same time.

The first rotation coupling member 230 may protrude from the outer surface of the magnetic body 210 . In addition, the first rotation coupling member 230 may be formed in plurality. In addition, the first rotation coupling member 230 can be coupled with a member having elasticity in the inner direction of the magnetic body 210, so when a force pressing the first rotation coupling member 230 is applied from the outside, the magnetic body 210 ), and can protrude again when the pressing force from the outside disappears.

Through this, the first rotational coupling member 230 protrudes only at the point where it meets the first rotational groove 331b and can be inserted and coupled into the first rotational groove 331b and does not meet the first rotational groove 331b. At the point where it is not, it is possible to maintain the inserted state inside the magnetic body 210.

In addition, when the first rotation coupling member 230 is drawn into the magnetic body 210, the magnetic body 210 and the inlet 250a of the filtering unit 300 may remain closed.

That is, the inner surface of the filtering unit 300 in close contact with the magnetic body 210 may be in a sealed state, and when the first rotation coupling member 230 is coupled to the inside of the first rotational groove 331b, the filtering unit ( 300) formed on the inner surface of the connector (not shown) coincides with the inlet 250a of the magnetic body 210, so that the purified water inside the filtering unit 300 flows into the magnetic body 210 and As the 210 moves downward, purified water may be discharged.

The first rotation coupling member 230 may be formed in a 'b' shape. Through this, it can be inserted into the first rotational groove 331b formed on the inner surface of the filtering unit 300 . At this time, the end of the protruding part from 'a' of the first rotation coupling member 230 may be formed in a clockwise or counterclockwise direction.

For example, the first rotation coupling member 230 may protrude from the outer surface of the magnetic body 210 in a direction perpendicular to the magnetic body 210 . In addition, the end of the vertically protruding portion of the magnetic body 210 may again protrude in the vertical direction.

At this time, when the magnetic body 210 rotates clockwise or counterclockwise in a state in which the end protruding back in the vertical direction is inserted into the first rotational groove 331b, inside the first rotational groove 331b. By being inserted in a clockwise or counterclockwise direction, the magnetic body 210 and the filtering unit 300 may be mutually coupled.

Through this, the first rotational coupling member 230 rotates clockwise or counterclockwise and can be fitted in one direction while being coupled to the first rotational groove 331b of the filtering unit 300, and the magnetic body ( 210) may be prevented from escaping according to the protruding direction and rotation.

At this time, clockwise and counterclockwise rotation may be determined according to the protruding direction of the 'L'-shaped first rotation coupling member 230, and the rotation direction is the plate portion of the filtering unit 300 to be described later. It can be formed to coincide with the direction of the second rotation coupling member 313c and the second rotation groove 311c formed in 310, so that when the magnetic body 210 rotates in one direction, the magnetic body 210 and filtering There is an effect that the coupling of the unit 300 can be firmly fixed according to the direction of rotation and at the same time the coupling between the filtering layers 330 can be strengthened.

Through this, the magnetic body 210 and the filtering unit 300, which are rotated for separation of filtration and purified water, can be further strengthened during rotation while preventing separation due to rotation, and the magnetic body 210 coupled to each other And the filtering unit 300 may have enhanced durability.

In addition, the magnetic body 210 includes a magnetic force generating unit 250 that is activated to generate backwash water when purified water is introduced into the inside and discharged downward, and when the purified water is discharged, it is necessary to generate backwash water. , A magnetic force generator 250 may be installed to generate magnetized water by ionizing the purified water passing through the flow path 255a.

For example, inside the magnetic body 210, the first magnetic body 251, the second magnetic body 253, and the molding part 255, which may be a plurality of layers, may be formed in a direction perpendicular to the bottom surface.

The first magnetic material 251 may have an N pole or an S pole. In addition, the first magnetic body 251 may be installed in close contact with the inner surface of the magnetic body 210 .

In addition, the first magnetic body 251 may be formed in a ring-shaped cross section, and a second magnetic body 253 spaced apart from the first magnetic body 251 may be installed in a space formed therein.

The second magnetic body 253 may be formed to form a polarity different from that of the first magnetic body 251 . Also, the second magnetic material 253 may be formed in a cylindrical shape. That is, the first magnetic body 251 may be formed in a ring-shaped cross section, and the second magnetic body 253 may be installed spaced apart from the first magnetic body 251 in a space formed inside the first magnetic body 251 .

In this case, a molding part 255 may be formed in a space between the first magnetic body 251 and the second magnetic body 253 . That is, between the first magnetic body 251 and the second magnetic body 253, a solid filtering medium having filtration efficiency may be formed and installed.

In this case, the molding part 255 may be formed of a material that does not interfere with the magnetism of the first magnetic body 251 and the second magnetic body 253 .

The molding unit 255 may mold a separation space between the first magnetic body 251 and the second magnetic body 253 between the first magnetic body 251 and the second magnetic body 253 . At this time, a flow path 255a may be formed inside the molding part 255 .

The upper end of the flow path 255a may have a diameter corresponding to that of the inlet 250a, so that when the flow path 255a and the inlet 250a coincide, purified water located inside the filtering unit 300 may be formed in the flow path 255a. ) can enter.

In this case, the passage 255a may be formed while rotating along the inner surface of the first magnetic material 251 and the outer surface of the second magnetic material 253 . Through this, the length of the passage 255a passing between the first magnetic body 251 and the second magnetic body 253 inside the magnetic body 210 is maximized, thereby extending the distance between the first magnetic body 251 and the second magnetic body 253. The ionization time of passing purified water can be extended, and thus the purified water can be magnetized.

At this time, the first magnetic body 251 and the second magnetic body 253 can generate magnetic force according to the user's selection, and the space where the first magnetic body 251 and the second magnetic body 253 are installed is not a magnetic body. It may be possible to generate general purified water by injecting a material to reduce magnetism.

That is, the magnetic force of the first magnetic body 251 and the second magnetic body 253 may selectively generate magnetic force.

Through this, it is possible to generate backwash water for backwashing by magnetizing the purified water and generating magnetized water by ionization of the purified water.

For example, when backwashing water is generated to clean the inside of the filtering unit 300, the generated magnetized water is reinjected into the filtering unit 300 through the first magnetic body 251 and the second magnetic body 253. By doing so, it is possible to improve the cleaning efficiency of the filter media positioned inside the filtering unit 300 .

In addition, by suppressing or turning off the magnetic force of the first magnetic body 251 and the second magnetic body 253 to discharge the purified water as it is, it may be possible to generate general purified water other than backwash water.
