Abstract

The present invention relates to a horizontal rod-supported, pore-controllable fiber media filter comprising: a fiber support comprising fixing supports to stand at both sides thereof and a plurality of horizontal rods which are coupled rotatably to the fixing supports in a zigzag pattern at intervals in a lengthwise direction of the fixing supports; a fiber media which hangs on the horizontal rods of the fiber support in a zigzag pattern, in which the lower end of the fiber media forms a fixed end attached to the lower end of the fiber support, and the upper end of the fiber media forms a free end at the upper end of the fiber support; and an actuator which is coupled to the free end of the fiber media to pull or relax the fiber media supported by the fixed end.

Claims

1. A horizontal rod-supported, pore-controllable fiber media filter comprising:

a fiber support comprising fixing supports to stand at both sides thereof and a plurality of horizontal rods which are coupled rotatably to the fixing supports in a zigzag pattern at intervals in a lengthwise direction of the fixing supports;

a fiber media which hangs on the horizontal rods of the fiber support in a zigzag pattern, in which the lower end of the fiber media forms a fixed end attached to the lower end of the fiber support, and the upper end of the fiber media forms a free end at the upper end of the fiber support; and

an actuator which is coupled to the free end of the fiber media to pull or relax the fiber media supported by the fixed end,

the fiber media filter being configured such that, when the actuator is driven to pull the fiber media, the fiber media forms filtration pores while being supported by the horizontal rods of the fiber support in a zigzag pattern,

when the actuator is driven to relax the fiber media, the fiber media is relaxed in a zigzag pattern to form backwashing pores,

the filtration and backwashing capacities of the fiber media filter are determined by the horizontal intervals, and

the rotatable coupling to the fixing supports absorbs a frictional force, which is caused by the pulling and relaxation of the fiber media, and transforms the force into rotational motion.

2. The horizontal rod-supported, pore-controllable fiber media filter of claim 1, wherein the fiber media filter is configured into a fiber media filter module wherein a pair of the fiber supports on which the fiber media is hung are symmetrically placed or placed in a continuous line, and the upper end of the fiber media is coupled to an upper coupling cover connected with the actuator, and a drainage port is formed at the central portion of the lower end of the fiber media.

3. The horizontal rod-supported, pore-controllable fiber media filter of claim 2, wherein the fiber media filter module is configured into a multi-stage filter module having a multi-layer fiber membrane by symmetrically placing a plurality of pairs of the fiber supports having the fiber media hang thereon or placing the plurality of pairs of the fiber supports having the fiber media hang thereon in a continuous line.

4. The horizontal rod-supported, pore-controllable fiber media filter of claim 3, wherein the thickness of the fiber media of the symmetrical or linearly-placed fiber supports in the multi-stage filter module differs between the pairs of the fiber supports so as to show a deep filtration effect.

5. A horizontal rod-supported fiber filter system comprising:

a filtration chamber comprising a raw water inlet pipe formed at an upper end of one side of the chamber, a backwashing water discharge pipe separate from the raw water inlet pipe and formed at the upper end of one side of the chamber, and a filtered-water drainage tub that is formed at a lower end of the chamber so as to communicate with an upper end of a filtered-water discharge pipe;

a fiber media filter module of claim 2, which is placed in the filtration chamber so as to couple an actuator to the upper end of the filtration chamber and couple a drainage port to communicate with the filtered-water discharge pipe, such that raw water introduced into the filter chamber is filtered through a fiber media and then discharged through the drainage port;

an air injection pipe which is placed in the filtered-water drainage tub, and has a plurality of branch pipes facing the fiber media filter module, and is connected with an external air pump so as to inject backwashing air according to a control signal; and

a drainage pipe which is connected to the filtered-water drainage tub so as to discharge filtered water or introduce backwashing water according to a control signal.

6. The horizontal rod-supported fiber filter system of claim 5, wherein the branch pipes of the air injection pipe are arranged so as to inject air onto both sides of the fiber media.

7. The horizontal rod-supported fiber filter system of claim 6, wherein a plurality of the fiber media filter modules are arranged in the filtration chamber.

8. The horizontal rod-supported fiber filter system of claim 5, wherein the horizontal rod-supported fiber filter system comprises:

a control unit for controlling a filtration process and a backwashing process; and

a water quality measurement sensor which measures the degree of pollution of raw water or filtered water and transmits the measurement to the control unit,

whereby the fiber filter system is automatically controlled such that the control unit outputs an actuator control signal according to a signal from the water quality measurement sensor during the filtration process such that filtration pores of the fiber media maintain water quality standards.

9. A horizontal rod-supported fiber filter system comprising:

a filtration chamber comprising a raw water inlet pipe provided at an upper end of one side of the chamber, a backwashing water discharge pipe which is separate from the raw water inlet pipe and formed at the upper end of one side of the chamber, and a filtered-water drainage tub which is placed on one sidewall of the chamber so as to communicate with a filtered-water discharge pipe;

a fiber media filter module of claim 2, which is placed in the filtration chamber so as to couple an actuator to the upper end of the filtration chamber and couple a drainage port to communicate with the filtered-water discharge pipe, such that raw water introduced into the filter chamber is filtered through a fiber media and then discharged through the drainage port;

an air injection pipe which is placed in the filtered-water drainage tub, and has a plurality of branch pipes facing the fiber media filter module, and is connected with an external air pump so as to inject backwashing air according to a control signal;

a drainage pipe which is connected to the filtered-water drainage tub so as to discharge filtered water or introduce backwashing water according to a control signal; and

a bottom air injection pipe which is placed at the bottom of the filtration chamber, has a plurality of bottom branch pipes facing the fiber media filter module, and is connected with an external air pump.

10. The horizontal rod-supported fiber filter system of claim 9, wherein a plurality of the fiber media filter modules are arranged in a layer structure in the filtration chamber.

11. The horizontal rod-supported fiber filter system of claim 9, wherein the horizontal rod-supported fiber filter system comprises:

a control unit for controlling a filtration process and a backwashing process; and

a water quality measurement sensor which measures the degree of pollution of raw water or filtered water and transmits the measurement to the control unit,

whereby the fiber filter system is automatically controlled such that the control unit outputs an actuator control signal according to a signal from the water quality measurement sensor during the filtration process such that the filtration pores of the fiber media maintain water quality standards.
