Description

가변 필터형 여과장치 {Filtration device having variable filter}Variable filter type filtering device {Filtration device having variable filter}

본 발명은 가변 필터형 여과장치에 관한 것이며, 보다 구체적으로는 압축력을 통해 필터의 공극 크기를 변경가능하여 원수를 여과되도록 하는 가변 필터형 여과장치에 관한 것이다.The present invention relates to a variable filter type filtration apparatus, and more particularly, to a variable filter type filtration apparatus for changing the pore size of the filter through the compressive force to filter the raw water.

일반적으로 원수를 여과하는 전처리 필터과정에서 사용되는 필터는 일회용 필터와 주기적으로 역세척을 실시하여 재생시키는 반영구 필터를 사용하고 있다. 그러나, 일회용 필터는 빈번한 교체로 인하여 비용상승의 문제점이 있어 반영구필터를 사용하는 비중이 증가하고 있는 추세이다. 그러나, 반영구 필터는 필터에 형성된 공극의 크기가 작으면 역세척을 실시하더라도 재생효율이 낮은 단점이 있고, 공극의 크기가 크면 재생효율은 크지만 미세입자의 여과효율이 떨어지는 문제점이 있다. 이에 최근에는 가변 필터를 사용하여 원수의 여과시에는 필터 공극의 크기를 작게 하고, 역세척을 통한 필터 재생시에는 필터 공극의 크기를 크게 하여 상기의 문제점을 해결하고 있다. 이러한 가변 필터는 보통 섬유줄을 이용하여 필터의 공극을 조절하는 방식이 사용된다. 이러한 섬유줄을 이용하는 공극조절 여과기는 여러 종류의 섬유 여재를 섬유줄의 형태로 만들어, 섬유줄 지지대와 조임쇠에 의해 반응조의 덮개에 고정한 후, 덮개와 연결된 걸림쇠와 조임나사에 의해 섬유줄 간의 공극을 미세 또는 확대 조절할 수 있도록 설계되었다. 그러나, 이러한 방식은 공극조절의 한계가 있으며, 섬유줄이 끊어지거나 느슨해지는 문제점이 발생되기도 하고, 원수의 압력으로 공극이 벌어질 수 있는 가능성이 있어 여과의 효율이 불안정해진다. 한편, 조임쇠를 풀어 섬유줄의 공극을 느슨하게 한 후에 역세척을 통하여 필터를 재생시킬 수 있으나, 조임쇠의 조임과 풀림의 지속적인 반복도 섬유줄이 느슨해지는 원인이 되어 여과 효율이 떨어지게 된다. 이러한 문제점을 해결하기 위해 섬유줄을 교체하게 되면, 역세척을 통해 소모품을 반영구적으로 사용하려는 본래의 취지가 퇴색되며 유지관리비용의 상승이 불가피하다.In general, the filter used in the pretreatment filter process to filter the raw water uses a disposable filter and a semi-permanent filter that is periodically backwashed and regenerated. However, since the disposable filter has a problem of cost increase due to frequent replacement, the proportion of the semi-permanent filter is increasing. However, the semi-permanent filter has a disadvantage in that the regeneration efficiency is low even when backwashing is performed when the size of the pore formed in the filter is small, and the regeneration efficiency is high when the size of the pore is large, but the filtering efficiency of the fine particles is low. In recent years, the above problem has been solved by using a variable filter to reduce the size of the filter pore when filtration of raw water and to increase the size of the filter pore when regenerating the filter through backwashing. Such a variable filter is usually used to control the air gap of the filter by using a fibrous wire. The pore control filter using the fibrous wire is made of various types of fibrous media in the form of fibrous wire, fixed to the cover of the reactor by the fibrous supporter and fasteners, and then the gap between the fibrous wires is secured by the clasp and the fastening screw connected to the cover. Designed to be fine or magnified. However, this method has a limitation of pore control, a problem of breaking or loosening of fibrous wires, and the possibility of opening of the pore due to pressure of raw water, which makes the filtration efficiency unstable. On the other hand, after loosening the fasteners to loosen the voids of the fibrous wire, the filter can be regenerated through backwashing, but the continuous repetition of tightening and loosening of the fasteners causes the fibrous wires to loosen, resulting in poor filtration efficiency. When the fibrous string is replaced to solve this problem, the original purpose of semi-permanent use of consumables through backwashing is faded, and the maintenance cost is inevitably increased.

The filtration device includes a plurality of support plates that are moved by the filter compression device to compress the filter to prevent the filter from twisting when the filter is compressed by the filter compression device, that is, to make the compression force compressing the filter constant. Is provided with a flange is provided with a guide coupled to the flange to guide the movable plate. The structure for preventing the filter from twisting is complicated and not easy to manufacture.

상기와 같은 본 발명으로 인하여, 육안으로 확인 가능한 큰 공극을 가지며 수축성과 탄력성이 좋은 발포성수지 필터를 사용하게 되므로, 역세척의 효율을 증 대시킬 수 있으며, 압축수단의 일정한 압축력 및 이를 필터에 인가하는 필터 지지판을 통하여, 필터의 공극의 일정한 유지가 가능하므로 여과 효율과 정밀도를 높일 수 있는 효과가 있다. 또한, 필터가 지지봉에 의해 지지되면서 압축되므로 압축수단(300)의 압축력이 복수의 필터(210,220)에 균일하게 전달되어 필터의 뒤틀림이 방지되는 효과가 있다. Due to the present invention as described above, it is possible to increase the efficiency of backwashing, because the use of a foamable resin filter having a large void that can be seen with the naked eye and good shrinkage and elasticity, and the constant compression force of the compression means and applied to the filter Through the filter support plate, it is possible to maintain a constant of the filter voids, there is an effect that can increase the filtration efficiency and precision.

In addition, since the filter is restored by using compressed air when the compression force of the filter for backwashing is released, the time required for restoring is shortened, so the backwashing time can be shortened, and the backwashing efficiency is improved by preventing the filter from being restored. There are advantages to it.

아울러, 편리한 필터의 역세척 방식을 사용하여 필터의 소모품 교체비용을 절감시킬 수 있는 효과가 있다.In addition, it is possible to reduce the cost of replacing the consumables of the filter by using a convenient filter backwash method.

The filter 210, 220 is supported by the support bar 250 and is compressed by the rising of the compression plate 240 by the compression means 300, so that the filter 210, 220 is compressed without being subjected to a constant pressure. Will be.

이때, 상기 지지봉(250)은 다수의 배출공(251)이 구비되고, 상기 압축수단(300)에 의한 상기 압축판(240) 하강시 상기 지지봉(250)으로 압축공기를 공급하여 상기 배출공(251)으로 배출된 압축공기에 의해 상기 필터(210,220)를 복원하도록 보조하는 압축공기 공급수단(미도시됨)이 더 구비된 것이 바람직하다. 상기 압축공기 공급수단은 압축공기를 공급할 수 있는 공지된 것을 사용하며 공기압축기(air compressor) 등을 사용할 수 있다. At this time, the support rod 250 is provided with a plurality of discharge holes 251, when the compression plate 240 is lowered by the compression means 300 to supply the compressed air to the support rod 250 by the discharge hole ( Preferably, compressed air supply means (not shown) is further provided to assist the restoration of the filters 210 and 220 by the compressed air discharged to the 251.

Accordingly, after the filters 210 and 220 filter in a state in which a compressive force is applied by the rising of the compression plate 240 by the compression means 300, the compression plate 240 by the compression means 300 is applied. When the compression is released by the lowering of the filter (210,220) contains the raw water, so that the restoring force is reduced, when the compressed air is discharged to the discharge hole 251 by supplying compressed air to the support rod 250 Compressed air improves the restoring force of the filters 210 and 220. As such, when the restoring force of the filters 210 and 220 is improved, the time taken for the filters 210 and 220 to be restored may be reduced, thereby reducing the backwashing time, and preventing the filter from being restored. do.

상기 압축수단(300)은 원수 여과시에 상기 압축판(240)을 상승시켜 상기 필터(210,220)에 압축력을 인가함으로써 상기 필터(210,220)의 공극을 작게 하고, 상기 필터(210,220) 역세척시는 상기 압축판(240)을 하강시켜 상기 필터(210,220)에 압축력을 해제시킴으로써 상기 필터(210,220)의 공극을 복귀되도록 하는 역할을 한다. The compression means 300 raises the compression plate 240 during raw water filtration to apply a compressive force to the filters 210 and 220 so as to reduce the air gaps of the filters 210 and 220, and to perform backwashing of the filters 210 and 220. By lowering the compression plate 240 to release the compressive force to the filter (210,220) serves to return the voids of the filter (210,220).

상기 압축수단(300)은 상측에는 하부 플레이트(102)를 통과하여 압축판(240)과 연결된 실린더 암(310)이 구비된다. 상기 압축판(240)은 압축수단(210)에서 인가된 압축력을 실린더 암(310)으로부터 전달받아 하우징(100) 내부에서 승하강되므로 상기 필터(210,220)에 압축력을 인가하거나 압축력을 해제시키게 된다. 최상부에 위치한 필터(210)의 상단에는 중공(231)이 형성된 상부지지판(230)이 구비되어, 상기 필터(210,220)에 인가되는 압축력을 지지한다.The compression means 300 has a cylinder arm 310 connected to the compression plate 240 through the lower plate 102 on the upper side. Since the compression plate 240 receives the compression force applied from the compression means 210 from the cylinder arm 310 and moves up and down inside the housing 100, the compression plate 240 applies a compression force to the filters 210 and 220 or releases the compression force. An upper support plate 230 having a hollow 231 is provided at an upper end of the filter 210 positioned at the top thereof to support the compressive force applied to the filters 210 and 220.

상기 필터 지지판(260)은 최상부에 위치한 필터(210)의 상부와 최하부에 위치한 필터(220)의 하부와 상기 필터(210,220) 사이에 각각 개재되어 상기 필터(210,220)에 작용하는 압축력을 분산시키며, 상기 필터(210,220)를 서로 연통시키는 역할을 한다. 이러한 필터 지지판(260)을 통하여 압축수단(300)에 의한 각각 의 필터(210,220)의 압축력이 분산되어 공급되므로 필터(210,220)의 공극은 균일해지게 된다. 또한, 압축수단(300)에 의한 각각의 필터(210,220)의 압축력이 분산되어 공급되므로 상기 필터(210,220)의 변형을 방지하는 역할도 하게 된다. The filter support plate 260 is interposed between the top of the filter 210 located at the top and the bottom of the filter 220 located at the bottom and the filters 210 and 220, respectively, to distribute the compressive force acting on the filters 210 and 220, The filters 210 and 220 serve to communicate with each other. Since the compressive force of each of the filters 210 and 220 by the compression means 300 is distributed and supplied through the filter support plate 260, the voids of the filters 210 and 220 become uniform. In addition, since the compressive force of each of the filters 210 and 220 by the compression means 300 is distributed and supplied, it also serves to prevent deformation of the filters 210 and 220.

상기 필터 지지판(260)은 탄성을 갖는 재질로 되어, 필터 압축시 각각의 필터(210,220)의 압축력이 분산되도록 하여 상기 필터(210,220)의 변형을 방지하는 역할을 수행함과 동시에 필터와 밀착되어 실링역할을 수행할 수 있다. The filter support plate 260 is made of an elastic material, and serves to prevent the deformation of the filters 210 and 220 by dispersing the compressive force of the filters 210 and 220 when compressing the filter, and at the same time, the filter supporting plate 260 is closely sealed to the filter. Can be performed.

상기 필터 지지판(260)은 상기 필터(210,220)의 내주연에 삽입 결합되어 상기 필터(210,220)에 결합되도록 하는 중공된 결합부(미도시됨)가 형성된 것이 바람직하다. The filter support plate 260 is preferably formed in the hollow coupling portion (not shown) to be inserted into the inner circumference of the filter (210,220) to be coupled to the filter (210,220).

도면에서는 필터의 개수를 총 2개로 도시하였으나, 이에 한정되는 것은 아니며 당업자의 수준에서 충분히 증감이 가능하다. 여러 개의 필터가 삽입되면, 각 필터 사이마다 필터 지지판(260)을 개재함으로써 각 필터에 인가되는 압력을 균일화시키고 각 필터의 공극이 균일해지는 효과가 있다.In the drawings, the number of filters is illustrated as a total of two, but the present invention is not limited thereto and may be sufficiently increased or decreased at the level of those skilled in the art. When a plurality of filters are inserted, the filter support plate 260 is interposed between the filters to equalize the pressure applied to the filters and to make the pores of the filters uniform.

When raw water is introduced through the raw water inlet 110, raw water is injected from the outer surfaces of the filters 210 and 220 so that a material larger than the voids remains outside the respective filters 210 and 220, and the treated water passed through the filters 210 and 220. Is discharged to the treated water outlet 120 through the upper support plate 230.

필터 역세척시는, 도 4b에서와 같이, 상기 압축수단(300)을 통하여 압축력을 해제시켜 압축판(240)을 하강시키면, 각 필터(210,220)는 다시 부풀게 되면서 각 필터(210,220)의 공극이 복귀된다. 상기 필터(210,220)의 복원력을 향상시키기 위해서는 상기 압축공기 공급수단에 의해 상기 지지봉(250)으로 압축공기를 공급하여 상기 배출공(251)으로 압축공기가 배출되도록 한다. 이렇게 되면 상기 필터(210,220)는 상기 배출공(251)으로 배출된 압축공기에 의해 복원이 향상되게 된다. When the filter is backwashed, as shown in FIG. 4B, when the compression plate 240 is released by releasing the compressive force through the compression means 300, the filters 210 and 220 are inflated again while the air gaps of the filters 210 and 220 are expanded. Is returned. In order to improve the restoring force of the filters 210 and 220, the compressed air is supplied to the support rod 250 by the compressed air supply unit so that the compressed air is discharged to the discharge hole 251. In this case, the filters 210 and 220 may be restored by the compressed air discharged into the discharge holes 251.

상기 필터(210,220)가 복원된 상태에서 역세척수 주입구(130)를 통하여 세척수를 공급하면 상부 지지판(230)을 통하여 필터(210,220) 내부에서 외측면으로 세척수가 이동되면서 상기 필터(210,220)의 외측면에 있는 불순물과 함께 원수 주입구(110)로 배출된다.When the washing water is supplied through the backwash water inlet 130 in the restored state of the filters 210 and 220, the washing water is moved from the inside of the filters 210 and 220 to the outside through the upper support plate 230, and then the outer surfaces of the filters 210 and 220. It is discharged to the raw water inlet 110 with impurities in the.
