Description

Crushed Fiber Filtration Equipment {FILTRATION DEVICE FOR COMPRESSIVE FIBER}

The present invention relates to a crimped fiber filtration device, and more particularly, to a crimped fiber filtration device for effectively separating and removing high turbidity suspended solids contained in raw water in various water treatment fields, such as water treatment and industrial wastewater treatment.

In general, wastewater, sewage and sewage pollute the environment, so the primary treatment water is made through the first purification process, and then discharged to the river or the sea. Contains suspended solids.

Suspended matter is a solid substance consisting of particles (organic and inorganic) having a size of 0.1 micron or more, and is also called a suspended substance in order to suspend water.

Waste water containing suspended solids (suspensions) (ie primary treated water and industrial water) is unsuitable for use as general water in domestic or industrial sites.

In addition, in order to purify river water, ground water, valley water, etc., and to use it as drinking water or living water, muddy water or pollutants may be introduced into raw water due to rainy season or indiscriminate development, which requires a pretreatment facility. Until now, the pretreatment facility, which is a primary treatment device, has been technically deteriorated, so that even the advanced water treatment device, which is a secondary and tertiary treatment device, has not been fully effective.

In other words, the filtration device for the primary treatment does not respond to changes in water quality and affects other expensive filters that are configured in stages, resulting in loss of filtration capacity. There was a problem such as that required.

Among the filtering devices developed to improve the problems of the prior art, Korean Patent No. 966889, Korean Patent No. 993788, Korean Patent No. 1011127 and Korean Patent No. 592083 have been published.

Among these prior arts, the filtration process of raw water according to Korean Patent No. 966889 (hereinafter referred to as 'prior art 1') controls the degree of mutual compression of filter plates having a foam foam disk shape made of a material such as a sponge. By adjusting the pore size corresponding to the water quality and rotating the filter plate to prevent foreign matter from adhering to or infiltrating the filter plate, the backwashing process period is increased.

The backwashing process of the prior art 1 releases the pressing force on the filter plate body so that the backwash water flows in the opposite direction to the flow of raw water, thereby rotating the filter plate body at a high speed so that the foreign matter is separated by centrifugal force.

However, according to the prior art 1, the filtration process has a problem that the filter plate body must be continuously rotated, the backwashing process can remain without the foreign matter that has penetrated between the pores in the filter plate body and the backwash water and the centrifugal force due to the high speed rotation There is a fear that the foam foam structure of the filter plate body may be damaged by the flow of foreign matter.

In addition, the filtration process of the raw water according to the Republic of Korea Patent No. 993788 (hereinafter referred to as 'prior art 2') of the prior art, to adjust the pores to the size corresponding to the water quality by compressing non-woven pieces or microfiber pieces. The backwashing process removes the debris and suspended solids by releasing the pressure applied to the nonwoven or microfiber chips and supplying backwash water and compressed air.

However, in the prior art 2, nonwoven fabric pieces or microfiber pieces are not fixed and may be partially pulled in the process of being pressed on the compression plate, and there is a difficulty in controlling uniform voids due to the pressure difference. Even in nonwoven fabric fragments or microfiber fragments there is a problem that is difficult to remove foreign matter.

Meanwhile, Korean Patent No. 1011127 (hereinafter referred to as 'prior art 3') and Korean Registered Patent No. 592083 (hereinafter referred to as 'prior art 4') among the prior arts, pores in response to filtration and cleaning. To control.

In particular, in the case of the prior art 4, the upper side and the lower side of the fiber yarn composed of a plurality of weft yarns are respectively fixed to the upper and lower nets, and the upper and lower nets are compressed to control the voids between the fiber yarns located therebetween. However, the fiber yarns fixed at the edges between the upper and lower nets have a problem that they cannot be compressed out of the upper and lower edges of the upper and lower nets during the compression of the upper and lower nets. Among them, since the flow resistance flows through the edge portion where there is relatively no resistance, it is difficult to perform a normal filtration function.

All the above-mentioned prior arts share the technical idea of compressing the filter to control the air gap for the filtration function, and releasing the pressure against the filter means and backwashing, but each of these filters is repeatedly used for a certain period of time. Even if the pressing force is released, the restoring force is lost, which causes a problem of decreasing the filtering ability and the cleaning efficiency.

It shows a drain valve 88 to discharge separately.

The filtration process and the backwashing process from the compressed fiber filtration device configuration according to the first embodiment of the present invention described above will be described sequentially with reference to the accompanying drawings.

First, the filtration process determines the degree of pressurization of the fibrous media 78 through the driving unit from information on the suspension degree of the raw water for filtering and the particle size of the suspended solids contained in the raw water.

The control unit controls the driving unit on the basis of the above-described information so as to pressurize the fibrous media 78 placed between the pressing plate 20 and the pressing plate 62.

At this time, the support frame 26 mounted on the upper side of the pressure plate 20 is guided by the guide rails 30 and the guide posts 28 and maintains the horizontal level by the weight as in the process proceeding from FIG. 1A to FIG. 1B. It descends along the pressure plate 20.

At the same time, each support 34 fixed to the support frame 26 and the plurality of links 36, 38, 40, 42 connected to the support 34, respectively, are bent or folded around the interconnected portion to form the housing 10. It is deformed into a shape that is contracted in a bellows shape with respect to the up and down direction.

In this case, the first link pin R / P1, the second link 38, and the third link to which the support 34 and the first link 36 are connected among the linking portions of the links 36, 38, 40, and 42. The upper roller 44 and the lower roller 48, which are respectively installed on the third link pins R / P3 to which the 40 is connected, gradually become closer to each other as the pressing plate 20 descends. Intermediate roller 46 connected to the second link pin (R / P2) of the form a shape that opens in a direction away from the pressure plate (20).

Accordingly, the fibrous media 78 forms a flat shape gradually in response to the arrangement change of the rollers 44, 46, and 48, and then the fiber placed between the pressing plate 20 and the pressing plate 62 by the lowering of the pressing plate 20. The media 78 is compressed by gradually shrinking the voids between the fiber strands constituting the fiber media 78 according to the pressure of the pressure plate 20.

Thereafter, the control unit blocks the valve V4 provided on the backwash water inlet pipe 66, the valve V5 installed on the effluent discharge pipe 14, and the valve V2 provided on the sediment discharge pipe 18, and blocks raw water. The valve V1 provided on the inlet pipe 12 and the valve V3 provided on the treatment part discharge pipe 64 are opened.

The raw water supplied from the raw water inlet pipe 12 is subjected to a first filtration process in which a suspended material having a high specific gravity sinks to the bottom of the sediment separation chamber 16 in the course of passing through the sediment separation chamber 16. The raw water then overflows from the sediment separation chamber 16 and flows into the housing 10.

The raw water flowing into the housing 10 passes through the pressure pad 22 and the fibrous media 78 compressed through a plurality of holes h formed in the pressure plate 20, and thus, the particulate suspended material contained in the raw water is contained. The filtered and treated inn is passed through the pressing plate 62 to the filtration chamber 60, and then is discharged through the open treated water discharge pipe 64.

If the filtration process of the raw water described above is continued for a certain time, a large amount of suspension material accumulates between the fibrous media 78, which eventually loses the filtration function for the raw water, from which the inside of the housing 10 is treated water. The pressure is increased by reducing the discharge of water and continuing the inflow of raw water.

When the pressure inside the housing 10 rises in this way, the check valve V6 installed on the bypass pipe 80 opens the bypass pipe 80 at the designed pressure to discharge the raw water.

The controller detecting this situation blocks the valve V1 installed on the raw water inlet pipe 12 and the valve V3 installed on the treated water discharge pipe 64 and the valve V4 provided on the backwash water inlet pipe 66. ) And the valve V5 provided on the effluent discharge pipe 14 and the valve V2 provided on the sediment discharge pipe 18 are opened and the driving unit is controlled to move the pressure plate 20 upward to proceed with the backwashing process. .

The progress of the backwashing process causes the sediment accumulated in the sediment separation chamber 16 to be discharged through the sediment discharge pipe 18 which is opened by the backwashing water flowing back to the sediment separation chamber 16. The valve V is first shut off.

On the other hand, the control unit by raising and lowering the pressure plate 20 by changing the support frame 26 connected to the pressure plate 20 so that each link (36, 38, 40, 42) in the folded state to expand in the vertical direction.

At this time, the fibrous media 78 wound around the rollers 44, 46, and 48 is released from the pressurized state by the pressure plate 20, and the respective fiber strands are separated from each other.

Subsequently, the fibrous media 78 stretches taut as the gap between the rollers 44, 46, and 48 is wider than when the fibrous media 78 is installed by the continuous upward movement of the pressure plate 20. At the same time, the thickness of each fiber strand is reduced in proportion to the elongated length so that the spacing between each fiber strand is further enlarged.

In this way, the elongation change of the fibrous media 78 and thus the expanded spacing between the fiber strands is not only easy to vibrate in response to the pulsation provided from the vibrators 70 and 72 or the ultrasonic oscillator 74 but also to supply washing water. Compressed air supplied through the nozzle 76 and the compressed air and the backwash water inlet pipe 66 supplied through the compressed air injection nozzle 68 together with the bubble effect caused by the flow of backwashed water and the cleaned air. It is easy to separate the suspended matter accumulated between the fiber strands.

As such, it can be expected that even repeating the process of compressing and stretching the fibrous media 78 in the backwashing process can separate even the suspended material penetrating into the fibrous media 78.

The strainer tube 124 is formed in the process in which the fibrous media 112 twisted in a spiral shape between the pressing plate 104 and the pressing plate 108 or 120 is pressed by the pressing plate 104 or the pressing plate 108 or 120. Limit outwards between.

That is, the function of the above-described strainer tube 124, each of the fiber strands of the fiber media 112 when the pressure plate 104 is lowered in the course of the backwash water flows through the center portion of the lower pressing plate 108 or 120 Due to the inflow of backwash water and the flow thereof, the pressure plate 104 and the compression plate 108 or 120 are pulled to a portion close to the inner wall of the strainer tube 124 and at the same time the pressure plate 104 or the compression plate 108 or 120 It is twisted and stacked by rotation.

On the other hand, from the configuration of the compressed fiber filtration device according to the second embodiment of the present invention described above with reference to the accompanying drawings, the filtration process and the back washing process will be described sequentially.

First, the filtration process lowers the pressure plate 104 of the pressurization unit by operating the cylinder 82 of the driving unit from the information on the suspension degree of the raw water to be filtered or the particle size of the suspended matter (suspension) contained in the raw water. Let's do it.

In this case, as shown in FIGS. 6A to 7, in response to a control signal of the controller, the rotating part rotates the pressing plate 104 or the pressing plate 120 in one direction in response to the lowering of the pressing plate 104 to form a fibrous material ( 112 are twisted and stacked in a spiral shape at mutually opposite edge site positions between the pressure plate 104 and the compression plate 108 or 120.

And, when the pressure plate 104 is further lowered, the voids between the fibrous media 112 become more dense.

When raw water is introduced from the above-described opening of the valve V1 on the raw water inlet pipe 12, first, the raw water in which the suspended solids with high specific gravity is filtered out through the sediment separation chamber 102 is overflowed, and thus the interior of the housing 100 is overflowed. The raw water is introduced into the filtered water chamber 110 through the pressing plate (108 or 120) is filtered while passing through the fibrous media (112) pressed and pressed between the pressing plate 104 and the pressing plate (108 or 120). The treated water, which has undergone filtration, is discharged by opening the valve V3 on the connected treated water discharge pipe 48.

As the filtration process of the raw water described above is repeatedly performed, a large amount of suspension material is accumulated in the above-described fibrous media 112, making it difficult to perform the filtering function.
