Description
本發明係關於：從屎尿之類的污泥(被處理液)分離出穿透液，而將被處理液予以濃縮的過濾篩裝置。The present invention relates to a filter and sieve device for separating the penetrating liquid from sludge such as feces and urine (the liquid to be treated) and concentrating the liquid to be treated.
例如：在污水處理場進行處理污泥時，用來將含在被處理液中的夾雜物分離出來的過濾篩，係採用：使用了線圈彈簧的過濾篩裝置。例如：專利文獻1所揭示的過濾篩裝置，當夾雜物堵塞在線圈彈簧的間隙時，就進行控制成：將銳角之線圈彈簧的端部彼此互相接觸來將夾雜物予以切斷來解除堵塞。For example: when treating sludge in a sewage treatment plant, the filter screen used to separate the inclusions contained in the liquid to be treated is a filter screen device using a coil spring. For example, in the filter device disclosed in Patent Document 1, when impurities clog the gaps of the coil springs, it is controlled such that the ends of the acute-angled coil springs come into contact with each other to cut off the inclusions and release the clogging.
又，專利文獻2所揭示之用來解除堵塞的過濾篩裝置，是將具備多數個搖擺片的旋轉軸配置在濾材體的內部之橫流式的過濾裝置。專利文獻2所開示的過濾篩裝置，是利用被處理液來使得旋轉驅動翼進行旋轉，進而使得旋轉軸進行旋轉，並且利用與濾材體接觸的搖擺片來解除堵塞。此外，根據專利文獻2，因為是將安裝有多數個搖擺片的旋轉軸配置在濾材體的內部，因此，被處理液所通過之濾材體的剖面積很小，與濾材體接觸之被處理液的流量很大，所以能夠提昇過濾效率。 [先前技術文獻] [專利文獻] Also, the filter screen device for unclogging disclosed in Patent Document 2 is a cross-flow type filter device in which a rotating shaft including a plurality of oscillating plates is arranged inside a filter medium body. In the filter screen device disclosed in Patent Document 2, the liquid to be treated is used to rotate the rotary drive blade, thereby rotating the rotating shaft, and the clogging is released by the swing piece in contact with the filter body. In addition, according to Patent Document 2, because the rotating shaft equipped with a plurality of wobble pieces is arranged inside the filter body, the cross-sectional area of the filter body through which the treated liquid passes is very small, and the treated liquid in contact with the filter body The flow rate is very large, so the filtration efficiency can be improved.

[專利文獻1]日本特許第6458962號公報 [專利文獻2]日本特開平10-272309號公報 [Patent Document 1] Japanese Patent No. 6458962 [Patent Document 2] Japanese Patent Application Laid-Open No. 10-272309
[發明所欲解決的問題][Problem to be solved by the invention]
然而，專利文獻1所揭示的過濾篩裝置，雖然構造單純且價格低廉，但是，基本上是以縱置設置來想定的過濾篩裝置，因此，如果將其做橫置設置的話，以線圈彈簧來形成的圓筒形將會撓曲成半月狀，開口(濾材體也就是線圈彈簧的間隙)的寬度(開口寬度)將會變得不一致，進而會在過濾篩的功能上造成問題。又，專利文獻1所揭示的過濾篩裝置，如果是做橫置設置的話，當穿透液從開口流出時，在線圈彈簧旁邊的流速將會變慢，因而在圓筒形的濾材體中，流動在濾材體內部的中心軸附近的被處理液就沒有與濾材體進行接觸，僅是單純地經過而已，將會降低過濾效率(或被處理液的濃縮效率)。因此，雖然可以考慮採用專利文獻2所揭示之能夠加大與濾材體進行接觸之被處理液的流量的習知技術，但是，安裝有多數個搖擺片之旋轉軸的構造很複雜且價格昂貴。 因此，本發明之目的是要提供：即使在橫置設置的情況下，還是可以保持開口大小的一致性且可以加大與濾材體進行接觸之被處理液的流量，又可以較低的成本來製造的過濾篩裝置。 [解決問題之技術手段] However, although the filter screen device disclosed in Patent Document 1 has a simple structure and low price, it is basically a filter screen device that is assumed to be installed vertically. The formed cylindrical shape will be bent into a half-moon shape, and the width (opening width) of the opening (filter body, that is, the gap of the coil spring) will become inconsistent, which will cause problems in the function of the filter screen. Also, if the filter screen device disclosed in Patent Document 1 is installed horizontally, when the penetrating liquid flows out from the opening, the flow velocity will slow down next to the coil spring, so in the cylindrical filter body, The liquid to be treated flowing near the central axis inside the filter body does not come into contact with the filter body, but simply passes through, which will reduce the filtration efficiency (or the concentration efficiency of the liquid to be treated). Therefore, although it is conceivable to adopt the conventional technology disclosed in Patent Document 2 that can increase the flow rate of the treated liquid in contact with the filter body, the structure of the rotating shaft on which a plurality of swinging pieces are installed is very complicated and expensive. Therefore, the purpose of the present invention is to provide: even in the case of horizontal arrangement, the consistency of the size of the opening can be maintained and the flow rate of the treated liquid in contact with the filter body can be increased, and the Manufactured filter sieve device. [Technical means to solve the problem]

[Effect of Invention]
根據本發明，係可以提供：即使在橫置設置的情況下，還是可以保持開口大小的一致性且可以加大與濾材體進行接觸之被處理液的流量，又可以較低的成本來製造的過濾篩裝置。According to the present invention, it is possible to provide: even in the case of a horizontal arrangement, the consistency of the size of the opening can be maintained and the flow rate of the liquid to be treated in contact with the filter body can be increased, and it can be manufactured at a lower cost Filter device.
茲佐以圖面來說明實施方式的過濾篩裝置如下。以下所示的結構等，都只是舉例說明而已，並沒有排除各種的變形和各種技術的應用之意圖。以下所示的結構等，只要是在未脫離本發明必須的構成要件及其要旨的範圍內，都可以做各種的變形來實施。The sieve device of the embodiment will be described with reference to the drawings as follows. The structures and the like shown below are just examples, and are not intended to exclude various modifications and applications of various technologies. The structures and the like shown below can be implemented with various modifications as long as they do not deviate from the essential components and gist of the present invention.
[1. 結構] 圖1是實施方式的過濾篩裝置1之說明圖。過濾篩裝置1是可以做橫置設置的裝置，用來將污泥、屎尿、或者這些的混合液(以下，也會將這些總稱為「被處理液W1」)予以分離成：穿透液PW以及含有夾雜物T的濃縮液W2。 此處所稱的「橫置」，係指：不僅是過濾篩裝置1的軸線L(後述)朝向與水平方向的方向，也包含朝向與水平方向傾斜的方向。例如：就被處理液W1的水流來觀看，以上游高於下游的方式，將軸線L對於水平方向的角度α設定在0°≦α＜75°的範圍之設置方式也被稱為「橫置」。另外，將「軸線L對於水平方向的角度β設定在75°≦β≦90°的範圍之設置方式」則是稱為「縱置」。 過濾篩裝置1雖然也可以設置成「縱置」，但是，即使是被設置成「橫置」的情況下，還是能夠恰當地進行固液分離或濃縮的裝置。 [1. Structure] FIG. 1 is an explanatory diagram of a sieve device 1 according to an embodiment. The filter screen device 1 is a device that can be installed horizontally, and is used to separate sludge, excrement, or these mixed liquids (hereinafter, these will also be collectively referred to as "processed liquid W1") into: penetrating liquid PW And concentrate W2 containing inclusion T. The term "horizontal" here refers to not only the direction in which the axis L (described later) of the filter device 1 faces the horizontal direction, but also the direction in which the axis L (described later) faces the horizontal direction. For example: from the perspective of the water flow of the treated liquid W1, the setting method of setting the angle α of the axis L to the horizontal direction in the range of 0°≦α<75° is also called "horizontal arrangement" ". In addition, the "installation method in which the angle β of the axis L with respect to the horizontal direction is set in the range of 75°≦β≦90°" is called "vertical arrangement". Although the sieve device 1 may be installed "vertically", even if it is installed "horizontally", it is still a device that can properly perform solid-liquid separation or concentration.
過濾篩裝置1，是將流動於由後述的衝孔金屬板2與線圈彈簧3所形成之圓筒形的過濾篩(濾材體)之內側的被處理液W1，予以分離成：穿透液PW、以及含有夾雜物T的濃縮液W2。藉由控制線圈彈簧3之開口的大小(開口寬度)，能夠實施所期望的固液分離和分級。 此外，過濾篩裝置1還具有：當過濾篩堵塞時，可以進行控制來使得線圈彈簧3之開口的大小(開口寬度)變小，藉此來將夾雜物T予以切斷而能夠解除堵塞的功能。 以下，將詳細說明過濾篩裝置1的結構。 The filter screen device 1 separates the liquid W1 to be treated flowing inside the cylindrical filter screen (filter material body) formed by the punched metal plate 2 and the coil spring 3 described later into: the penetrating liquid PW , and the concentrate W2 containing inclusions T. Desired solid-liquid separation and classification can be implemented by controlling the size (opening width) of the opening of the coil spring 3 . In addition, the filter screen device 1 also has the function that when the filter screen is clogged, it can be controlled so that the size of the opening (opening width) of the coil spring 3 becomes smaller, thereby cutting off the inclusions T and releasing the clogging function. . Hereinafter, the structure of the sieve device 1 will be described in detail.
過濾篩裝置1至少具有兩個單元10，該單元10是具備：形成有複數個孔h之圓筒形的衝孔金屬板2；與衝孔金屬板2保持同心地被配置在衝孔金屬板2的徑向外側且包覆著衝孔金屬板2之形成有孔h的部分之線圈彈簧3；從外側包覆著線圈彈簧3之外筒4；可使線圈彈簧3進行伸縮之驅動裝置5。雖然一個單元是如後述的圖3所示般地，具有三個驅動裝置5，但是在圖1中，為了簡化圖示起見，在一個單元中只顯示出一個驅動裝置5。 本實施方式，雖然是舉出具備三個單元10之橫置的過濾篩裝置1的例子，但是，單元10的個數可以是兩個，也可以是四個以上。又，過濾篩裝置1是具有用來控制各單元10的驅動裝置5之控制裝置20。 包含在一個單元10內之衝孔金屬板2的外徑與線圈彈簧3的內徑，雖然在實質上是屬相同，但是，線圈彈簧3的內徑還是稍微大於衝孔金屬板2的外徑。 The filter screen device 1 has at least two units 10. The unit 10 is equipped with: a cylindrical punched metal plate 2 formed with a plurality of holes h; A coil spring 3 that covers the radially outer side of 2 and covers the part of the punched metal plate 2 where the hole h is formed; an outer cylinder 4 that covers the coil spring 3 from the outside; a drive device 5 that enables the coil spring 3 to expand and contract . Although one unit has three driving devices 5 as shown in FIG. 3 described later, in FIG. 1 , only one driving device 5 is shown in one unit for the sake of simplification of illustration. In the present embodiment, an example is given of the horizontally placed filter sieve device 1 provided with three units 10 , but the number of units 10 may be two or four or more. In addition, the sieve device 1 has a control device 20 for controlling the driving device 5 of each unit 10 . Although the outer diameter of the punched metal plate 2 contained in one unit 10 and the inner diameter of the coil spring 3 are substantially the same, the inner diameter of the coil spring 3 is still slightly larger than the outer diameter of the punched metal plate 2 .
三個單元10是沿著被處理液W1的流動方向(水流方向)做串聯配置。在以下的說明中，有對於三個單元10加以區別時，是依照從流動方向的上游側往下游側的順序，依序稱為：第一單元10A、第二單元10B、第三單元10C。又，要對於分別被包含在三個單元10內的衝孔金屬板2、線圈彈簧3、外筒4及驅動裝置5加以區別時，則是配合具備各構成要素2～5的單元10(從上游側往下游側的順序)，除了在該構成要素的前頭加上「第一」～「第三」之外，也在該符號的末尾加上A～C。The three units 10 are arranged in series along the flow direction (water flow direction) of the liquid to be treated W1. In the following description, when the three units 10 are distinguished, they are referred to as the first unit 10A, the second unit 10B, and the third unit 10C in order from the upstream side to the downstream side of the flow direction. Also, when it is necessary to distinguish the punched metal plate 2, the coil spring 3, the outer cylinder 4, and the driving device 5 included in the three units 10, the unit 10 having the respective constituent elements 2 to 5 (from In order from the upstream side to the downstream side), in addition to adding "first" to "third" at the beginning of the component, A to C are also added at the end of the symbol.
分別被包含在三個單元10內的三個衝孔金屬板2，雖然都是呈圓筒形狀，但是，各自的內徑都不同。三個衝孔金屬板2雖然是呈串聯配置，但是，就被處理液的水流方向觀看，其配置方式為：配置在上游之衝孔金屬板2的內徑是大於配置在其下游之衝孔金屬板2的內徑。換言之，就被處理液的水流方向觀看，被配置在下游之衝孔金屬板2的內徑是小於被配置在其上游之衝孔金屬板2的內徑。 三個衝孔金屬板2都是以中心軸與軸線L一致而形成一直線的方式，呈同軸且串聯地配置。被處理液W1是被供給到位於最上游側之第一衝孔金屬板2A的內側。 相鄰的衝孔金屬板2彼此之間，是利用：就被處理液的水流方向觀看，從上游往下游內徑變小之圓錐筒形狀的連接管(12A或12B)而連接在一起。 具體而言，第一衝孔金屬板2A的下游端與第二衝孔金屬板2B的上游端是利用第一連接管12A而連接在一起，第二衝孔金屬板2B的下游端與第三衝孔金屬板2C的上游端是利用第二連接管12B而連接在一起。 The three punched metal plates 2 included in the three units 10 are all cylindrical, but have different inner diameters. Although the three perforated metal plates 2 are arranged in series, as viewed from the flow direction of the treated liquid, the arrangement is as follows: the inner diameter of the punched metal plate 2 arranged upstream is larger than the punched hole arranged downstream The inner diameter of the metal plate 2. In other words, the inner diameter of the punched metal plate 2 disposed downstream is smaller than the inner diameter of the punched metal plate 2 disposed upstream thereof when viewed in the flow direction of the liquid to be treated. The three punched metal plates 2 are arranged coaxially and in series so that the central axis coincides with the axis L to form a straight line. The liquid to be treated W1 is supplied to the inside of the first punched metal plate 2A located on the most upstream side. Adjacent punching metal plates 2 are connected together by means of conical tube-shaped connecting pipes (12A or 12B) whose inner diameters become smaller from upstream to downstream as viewed in the flow direction of the liquid to be treated. Specifically, the downstream end of the first punched metal plate 2A and the upstream end of the second punched metal plate 2B are connected together by a first connecting pipe 12A, and the downstream end of the second punched metal plate 2B is connected to the third The upstream ends of the punched metal plates 2C are connected together by a second connecting pipe 12B.
此外，第一衝孔金屬板2A的上游端是被固定在：用來將被處理液W1導入過濾篩裝置1之入口配管11，第三衝孔金屬板2C的下游端是被固定在：用來排出從被處理液W1分離出來的濃縮液W2之出口配管13。入口配管11、第一連接管12A、第二連接管12B及出口配管13都是呈可供被處理液W1在其內部流動的圓筒形狀，並且都是被配置成與衝孔金屬板2的軸線L近乎同一圓心。 此外，在第一連接管12A、第二連接管12B、出口配管13之上游側的外表面，配置且固定著圓形的凸緣部17，該凸緣部17是從該外表面朝徑向突出且是呈以軸線L為中心的圓形。 In addition, the upstream end of the first punching metal plate 2A is fixed on the inlet pipe 11 for introducing the liquid W1 to be treated into the filter screen device 1, and the downstream end of the third punching metal plate 2C is fixed on: An outlet pipe 13 for discharging the concentrated liquid W2 separated from the liquid to be treated W1. The inlet pipe 11, the first connecting pipe 12A, the second connecting pipe 12B, and the outlet pipe 13 are all in the shape of a cylinder in which the liquid to be treated W1 can flow, and are arranged so as to be connected to the punched metal plate 2. Axis L is close to the same center. In addition, on the outer surface on the upstream side of the first connecting pipe 12A, the second connecting pipe 12B, and the outlet pipe 13, a circular flange portion 17 is arranged and fixed, and the flange portion 17 extends radially from the outer surface. It protrudes and is circular with the axis L as the center.
如後所述般地，控制裝置20雖然可使線圈彈簧3進行伸縮，但是，入口配管11、第一衝孔金屬板2A、第一連接管12A、第二衝孔金屬板2B、第二連接管12B、第三衝孔金屬板2C、以及出口配管13的長度都是既定的固定長度，因此，無論線圈彈簧3處於何種伸縮狀態，從入口配管11至出口配管13的長度都不會改變。As will be described later, although the control device 20 can expand and contract the coil spring 3, the inlet pipe 11, the first punched metal plate 2A, the first connecting pipe 12A, the second punched metal plate 2B, and the second connection The lengths of the pipe 12B, the third punched metal plate 2C, and the outlet pipe 13 are all predetermined fixed lengths. Therefore, the length from the inlet pipe 11 to the outlet pipe 13 does not change regardless of the expansion and contraction state of the coil spring 3. .
如圖2(a)所示般地，形成在各衝孔金屬板2之複數個孔h的直徑是被設定成：較諸被配置在各衝孔金屬板2的外側之線圈彈簧3的開口更大。線圈彈簧3之開口的大小，基本上是被設定成：不會讓夾雜物T通過的大小。 因此，過濾篩裝置1可以從流動在衝孔金屬板2的內部之被處理液W1，並且是從圓筒形的衝孔金屬板2及線圈彈簧3之徑向的內側往外側將穿透液PW予以分離出來，從被處理液W1中被除去了穿透液PW後之濃縮且含有夾雜物T的濃縮液W2則是朝軸線L方向排出。 As shown in FIG. 2( a), the diameters of the plurality of holes h formed in each punched metal plate 2 are set to be larger than the openings of the coil springs 3 disposed on the outside of each punched metal plate 2. bigger. The size of the opening of the coil spring 3 is basically set so as not to allow foreign matter T to pass therethrough. Therefore, the filter screen device 1 can flow the penetrating liquid W1 from the inside of the punched metal plate 2, and from the inside to the outside in the radial direction of the cylindrical punched metal plate 2 and the coil spring 3. The PW is separated, and the concentrated liquid W2 containing the inclusions T after the penetration liquid PW has been removed from the liquid to be treated W1 is discharged in the direction of the axis L.
如前所述般地，三個衝孔金屬板2愈是位於下游，其內徑被設定為愈小。換言之，係如圖1所示般地，第二衝孔金屬板2B的內徑D2被設定成小於第一衝孔金屬板2A的內徑D1，第三衝孔金屬板2C的內徑D3被設定成小於第二衝孔金屬板2B的內徑D2。換言之，處於D1＞D2＞D3的關係。As described above, the more downstream the three punched metal plates 2 are, the smaller their inner diameters are set. In other words, as shown in FIG. 1, the inner diameter D2 of the second punched metal plate 2B is set smaller than the inner diameter D1 of the first punched metal plate 2A, and the inner diameter D3 of the third punched metal plate 2C is set to be smaller than the inner diameter D1 of the first punched metal plate 2A. It is set to be smaller than the inner diameter D2 of the second punched metal plate 2B. In other words, there is a relationship of D1>D2>D3.
從入口配管11導入的被處理液W1係被供給到第一衝孔金屬板2A的內部。然後，被處理液W1在依序地流經過第一衝孔金屬板2A、第一連接管12A、第二衝孔金屬板2B、第二連接管12B及第三衝孔金屬板2C之內部的同時，利用各單元10將穿透液PW分離出來，只剩下濃縮液W2從出口配管13排出。在圖1及圖2中，是以中空箭頭來表示穿透液PW。The liquid to be treated W1 introduced from the inlet pipe 11 is supplied to the inside of the first punched metal plate 2A. Then, the liquid W1 to be treated sequentially flows through the inside of the first punched metal plate 2A, the first connecting pipe 12A, the second punched metal plate 2B, the second connecting pipe 12B and the third punched metal plate 2C. At the same time, the permeate PW is separated by each unit 10 , and only the concentrate W2 is discharged from the outlet pipe 13 . In FIGS. 1 and 2 , the penetrating liquid PW is indicated by a hollow arrow.
分別被包含在三個單元10內的線圈彈簧3，都是由被捲繞成螺旋狀且被配置成與軸線L近乎同一圓心的線材6所構成的。被包含在一個單元內之線圈彈簧3的內徑，實質上是與配置在該線圈彈簧3的內側之衝孔金屬板2的外徑相同且稍微大於該外徑。 此外，構成各單元10的線圈彈簧3之線材6的粗細、剖面形狀等的條件，也沒有必要在所有的單元10中都是相同。 Each of the coil springs 3 included in the three units 10 is composed of a wire 6 wound in a helical shape and arranged so as to be substantially concentric with the axis L. As shown in FIG. The inner diameter of the coil spring 3 included in one unit is substantially the same as and slightly larger than the outer diameter of the punched metal plate 2 arranged inside the coil spring 3 . In addition, conditions such as the thickness and cross-sectional shape of the wire 6 of the coil spring 3 constituting each unit 10 are not necessarily the same in all the units 10 .
如圖2所示般地，將線材6進行捲繞而構成的各線圈彈簧3，係具有：螺旋狀的圓筒面也就是第一面61、以及與第一面61所形成的夾角θ為銳角之螺旋狀的斜面也就是第二面62。 此處所示的線材6的例子，係如圖2(a)及圖2(b)所示般地，是具有：由面對徑向內側的第一面61與面對徑向外側之一對第二面62所組成之三角形狀的剖面。雖然第一面61與第二面62所形成的夾角θ是設定在30°～70°為佳，但是，只要是銳角即可，不限於只落在這個範圍內。 As shown in Figure 2, each coil spring 3 formed by winding the wire 6 has: a helical cylindrical surface, that is, a first surface 61, and an angle θ formed with the first surface 61 of The helical inclined surface with an acute angle is also the second surface 62 . The example of wire rod 6 shown here is as shown in Fig. 2 (a) and Fig. 2 (b), is to have: by the first face 61 that faces radially inner side and one of facing radially outer side The cross section of the triangular shape formed by the second surface 62. Although the angle θ formed by the first surface 61 and the second surface 62 is preferably set at 30°-70°, it is not limited to fall within this range as long as it is an acute angle.
在軸線L方向(被處理液W1的流動方向)上相鄰的線材6的第一面61，彼此都是形成相同內徑之圓筒的內壁。在軸線L方向上相鄰的線材6之各自的第二面62則是以朝往徑向外側逐漸互相分開的方式形成第二面62。The first surfaces 61 of the wires 6 adjacent in the direction of the axis L (the flow direction of the liquid to be treated W1 ) form the inner walls of cylinders with the same inner diameter. The respective second surfaces 62 of the adjacent wires 6 in the direction of the axis L form the second surfaces 62 in such a manner that they are gradually separated from each other toward the radially outer side.
相鄰的線材6是隨著線圈彈簧3在軸線L方向上的伸縮而互相分離或互相接近。圖2(a)是利用控制裝置20將線圈彈簧3予以拉伸時之線材6的剖面圖，圖2(b)是利用控制裝置20將線圈彈簧3予以壓縮時之線材6的剖面圖。 如圖2(a)所示般地，線圈彈簧3被拉伸時，在軸線L方向上相鄰的線材6將會互相分離，而在兩者之間形成了間隙G。基本上，線圈彈簧3的間隙G雖然是被設計成：不會讓含在被處理液W1內的夾雜物T通過，但是，未含夾雜物T的穿透液PW、或者，僅含有可通過間隙G之較小的夾雜物T之穿透液PW，都可以從線材6之間的間隙G往線圈彈簧3之徑向外側流出。 另一方面，如果有一部分較大的夾雜物T夾在線圈彈簧3的間隙G而成為堵塞的原因時，就如圖2(b)所示般地，利用控制裝置20將線圈彈簧3予以壓縮，相鄰的線材6彼此都利用第一面61與第二面62之間的稜線R來進行線接觸。如此一來，造成堵塞的原因之夾雜物T將會被該進行線接觸之兩個稜線R所切斷而得以解除堵塞。 Adjacent wires 6 are separated from each other or approached to each other as the coil spring 3 expands and contracts in the axis L direction. 2( a ) is a sectional view of the wire 6 when the coil spring 3 is stretched by the control device 20 , and FIG. 2( b ) is a sectional view of the wire 6 when the coil spring 3 is compressed by the control device 20 . As shown in FIG. 2( a ), when the coil spring 3 is stretched, the adjacent wires 6 in the direction of the axis L are separated from each other, and a gap G is formed therebetween. Basically, the gap G of the coil spring 3 is designed not to allow the inclusions T contained in the treated liquid W1 to pass through, but the penetrating liquid PW containing no inclusions T or only containing The penetrating liquid PW of the small inclusions T in the gap G can all flow out from the gap G between the wires 6 to the radially outer side of the coil spring 3 . On the other hand, if some large inclusions T are caught in the gap G of the coil spring 3 and become the cause of clogging, the coil spring 3 is compressed by the control device 20 as shown in FIG. 2( b ). , adjacent wires 6 are in line contact with each other through the ridgeline R between the first surface 61 and the second surface 62 . In this way, the inclusion T that causes the clogging will be cut off by the two ridges R that are in line contact, and the clogging can be released.
如圖1所示般地，第一線圈彈簧3A的上游端是被固定在入口配管11，第二線圈彈簧3B的上游端是被固定在第一連接管12A，第三線圈彈簧3C的上游端是被固定在第二連接管12B。As shown in Figure 1, the upstream end of the first coil spring 3A is fixed to the inlet pipe 11, the upstream end of the second coil spring 3B is fixed to the first connecting pipe 12A, and the upstream end of the third coil spring 3C is fixed to the second connecting pipe 12B.
各線圈彈簧3的下游端，是被固定在：被配置成與軸線L近乎同一圓心並且可在衝孔金屬板2上沿著軸線L方向進行滑動的內筒7。 內筒7係具備：圓筒狀的圓筒部71、以及從圓筒部71之外周面的一部分(較諸線圈彈簧3的固定地方更下游側的部分)往徑向外側突出的平板部72。換言之，平板部72是被固定在圓筒部71的外周面上。 圓筒部71的內徑是與被配置在各線圈彈簧3的內側之衝孔金屬板2的外徑同等或者稍微大一點，並且圓筒部71的外徑是與供衝孔金屬板2的下游端進行固定之配管(第一連接管12A、第二連接管12B或出口配管13)之上游端的內徑同等或者稍微小一點。 圓筒部71之下游側的端部，是可滑動地***於衝孔金屬板2與上述的配管之間的間隙。平板部72是用來與驅動裝置5的驅動桿進行連接的部位，例如：圖3所示般地，從軸線L的方向觀看，係呈圓角的三角形狀。在平板部72的各角部是供驅動裝置5的驅動桿(可從驅動裝置5推出及可縮入驅動裝置5內)進行固定。 The downstream end of each coil spring 3 is fixed to an inner cylinder 7 that is arranged approximately at the same center as the axis L and is slidable in the direction of the axis L on the punched metal plate 2 . The inner cylinder 7 is provided with a cylindrical cylindrical portion 71 and a flat plate portion 72 protruding radially outward from a part of the outer peripheral surface of the cylindrical portion 71 (a portion on the downstream side from where the coil springs 3 are fixed). . In other words, the flat plate portion 72 is fixed on the outer peripheral surface of the cylindrical portion 71 . The inner diameter of the cylindrical portion 71 is equal to or slightly larger than the outer diameter of the punched metal plate 2 arranged inside each coil spring 3 , and the outer diameter of the cylindrical portion 71 is the same as that of the punched metal plate 2 . The inner diameter of the upstream end of the piping (the first connecting pipe 12A, the second connecting pipe 12B, or the outlet piping 13 ) to which the downstream end is fixed is the same or slightly smaller. The downstream end of the cylindrical portion 71 is slidably inserted into the gap between the punched metal plate 2 and the above-mentioned piping. The flat plate portion 72 is used to connect with the driving rod of the driving device 5, and is, for example, as shown in FIG. Each corner of the flat plate portion 72 is fixed for the driving rod of the driving device 5 (which can be pushed out from the driving device 5 and retracted into the driving device 5).
外筒4係具備：保有間隔地配置在線圈彈簧3的徑向外側且與軸線L近乎同一圓心的主圓筒部41；被安裝在主圓筒部41之上游側的開口之環狀的上游側端面部42；以及被安裝在主圓筒部41之下游側的開口之環狀的下游側端面部43。 各單元10之外筒4的上游側端面部42，其環狀的內周端面是被固定在用來固定各線圈彈簧3的上游端之配管。具體而言，第一外筒4A的上游側端面部42是被固定在入口配管11，第二外筒4B的上游側端面部42是被固定在第一連接管12A，第三外筒4C的上游側端面部42是被固定在第二連接管12B。又，外筒4之下游側端面部43之環狀的內周端面，例如：是夾介著油封之類的密封構件而抵接於內筒7的外周面。如此一來，外筒4就從外側包覆著線圈彈簧3，並且在線圈彈簧3與外筒4之間形成了空間(穿透液側空間)。 The outer cylinder 4 is provided with: a main cylindrical portion 41 disposed on the radially outer side of the coil spring 3 at a distance and approximately concentric with the axis L; the side end surface 42 ; and the annular downstream side end surface 43 attached to the opening on the downstream side of the main cylindrical portion 41 . The upstream end surface 42 of the outer cylinder 4 of each unit 10 has its annular inner peripheral end surface fixed to a pipe for fixing the upstream end of each coil spring 3 . Specifically, the upstream end surface 42 of the first outer cylinder 4A is fixed to the inlet pipe 11, the upstream end surface 42 of the second outer cylinder 4B is fixed to the first connecting pipe 12A, and the third outer cylinder 4C. The upstream end surface 42 is fixed to the second connecting pipe 12B. Furthermore, the annular inner peripheral end surface of the downstream side end surface portion 43 of the outer cylinder 4 abuts against the outer peripheral surface of the inner cylinder 7 via, for example, a seal member such as an oil seal. In this way, the outer cylinder 4 wraps the coil spring 3 from the outside, and a space (a penetrating liquid side space) is formed between the coil spring 3 and the outer cylinder 4 .
在外筒4之主圓筒部41之下側的外表面連接著用來排出穿透液PW的穿透液排出管14。穿透液排出管14係具備：複數個分岔管14a與一個匯流管14b，各個分岔管14a是分別位於各單元10的外筒4所具有的主圓筒部41之上游側，並且連接於該主圓筒部41的下側，而該匯流管14b則是用來連接各分岔管14a之下游側的其中一端部。 在各外筒4的主圓筒部41形成有開口，在這個開口的位置處，將各分岔管14a的另外一端部設成與該開口連通的狀態。穿透液PW是從線圈彈簧3與外筒4之間的空間通過分岔管14a而在匯流管14b內進行匯流之後才送往例如：未圖示的穿透液儲存槽。 A penetrating liquid discharge pipe 14 for discharging the penetrating liquid PW is connected to the outer surface on the lower side of the main cylindrical portion 41 of the outer cylinder 4 . The penetrating liquid discharge pipe 14 is provided with: a plurality of branch pipes 14a and a confluence pipe 14b, and each branch pipe 14a is respectively located on the upstream side of the main cylindrical part 41 of the outer cylinder 4 of each unit 10, and is connected to On the lower side of the main cylindrical portion 41, the confluence pipe 14b is used to connect one of the downstream ends of the branch pipes 14a. An opening is formed in the main cylindrical portion 41 of each outer cylinder 4, and at the position of this opening, the other end portion of each branch pipe 14a is provided in a state of communicating with the opening. The penetrating liquid PW flows from the space between the coil spring 3 and the outer cylinder 4 through the branch pipe 14 a and then flows into the converging pipe 14 b before being sent to, for example, a not-shown penetrating liquid storage tank.
又，在外筒4之主圓筒部41之上側的外表面，形成有用來將清洗液CW導入過濾篩裝置1的開口，清洗液導入管15的其中一端是被設置在這個開口的位置且保持連通狀態。連接於各外筒4之主圓筒部41之清洗液導入管15的另外一端則是連接到清洗液供給裝置30。 清洗液供給裝置30是受到控制裝置20的控制，當線圈彈簧3發生了堵塞時，就經由清洗液導入管15將清洗液CW供給到線圈彈簧3與外筒4之間的空間來實施逆洗。從清洗液導入管15導入的清洗液CW，係可以利用例如：被儲存在上述穿透液儲存槽內的穿透液PW。 如果沒有使用被儲存在上述穿透液儲存槽內的穿透液PW，而是使用其他的液體來作為清洗液CW時，為了避免這種其他的液體進入穿透液儲存槽，最好是將各單元10的清洗液CW都予以匯流到匯流管14b內，並且利用配置在流入穿透液儲存槽前的配管中的三向閥(未圖示)來將用來實施逆洗後的清洗液CW排出到系統之外為佳。 此外，雖然在各單元10中，用來連接穿透液排出管14的開口是被設在主圓筒部41之靠近上游端處，用來連接清洗液導入管15的開口是被設在主圓筒部41之靠近下游端處，但是用來穿透液排出管14及清洗液導入管15之開口的位置並不限於此處。 Also, on the outer surface of the upper side of the main cylindrical part 41 of the outer cylinder 4, an opening for introducing the cleaning liquid CW into the filter screen device 1 is formed, and one end of the cleaning liquid introduction pipe 15 is arranged at the position of the opening and held. connected state. The other end of the cleaning liquid introduction pipe 15 connected to the main cylindrical portion 41 of each outer cylinder 4 is connected to the cleaning liquid supply device 30 . The cleaning liquid supply device 30 is controlled by the control device 20. When the coil spring 3 is clogged, the cleaning liquid CW is supplied to the space between the coil spring 3 and the outer cylinder 4 through the cleaning liquid introduction pipe 15 to perform backwashing. . The cleaning liquid CW introduced from the cleaning liquid introduction pipe 15 can be, for example, the penetrating liquid PW stored in the above-mentioned penetrating liquid storage tank. If the penetrating liquid PW stored in the above penetrating liquid storage tank is not used, but other liquid is used as the cleaning liquid CW, in order to prevent this other liquid from entering the penetrating liquid storage tank, it is better to put The cleaning liquid CW of each unit 10 is collected into the confluence pipe 14b, and the cleaning liquid CW used for backwashing is diverted by a three-way valve (not shown) arranged in the piping before flowing into the penetrating liquid storage tank. It is preferable to discharge CW out of the system. In addition, although in each unit 10, the opening for connecting the penetrating liquid discharge pipe 14 is provided near the upstream end of the main cylindrical portion 41, the opening for connecting the cleaning liquid introduction pipe 15 is provided at the main cylindrical portion 41. The position of the opening of the cylindrical portion 41 near the downstream end, but for the penetrating liquid discharge pipe 14 and the cleaning liquid introduction pipe 15, is not limited thereto.
如圖1及圖3所示般地，外筒4的下游側端面部43係具有：較諸主圓筒部41的外周面更往徑向外側延伸出去的延伸部43a。驅動裝置5是被固定在延伸部43a之面對下游側的這一面。此外，延伸部43a是藉由支架部73而被固定在：設置於用來固定一個單元10的衝孔金屬板2的下游端之配管(第一連接管12A、第二連接管12B或出口配管13)上的凸緣部17。換言之，棒狀之支架部73的其中一端是被固定在延伸部43a，支架部73的另外一端是被固定在凸緣部17。如此一來，即可穩定地控制驅動裝置5所具備之驅動桿的伸縮距離。As shown in FIGS. 1 and 3 , the downstream end surface 43 of the outer cylinder 4 has an extension portion 43 a extending radially outward from the outer peripheral surface of the main cylindrical portions 41 . The drive unit 5 is fixed to the downstream side of the extending portion 43a. In addition, the extension part 43a is fixed by the bracket part 73 on the pipe (the first connecting pipe 12A, the second connecting pipe 12B or the outlet pipe) provided at the downstream end of the punched metal plate 2 for fixing one unit 10. 13) The flange portion 17 on the top. In other words, one end of the rod-shaped support portion 73 is fixed to the extension portion 43 a, and the other end of the support portion 73 is fixed to the flange portion 17 . In this way, the telescopic distance of the driving rod included in the driving device 5 can be stably controlled.
驅動裝置5係可採用：具備在內部設有活塞的氣缸體、以及與活塞設成一體的驅動桿的氣壓缸之類的裝置。驅動桿的前端是被固定在平板部72。因此，驅動裝置5利用氣壓缸來將驅動桿予以推出去或拉回去，就可以使得內筒7沿著軸線L方向(被處理液W1的流動方向)宛如被推出去或被拉回去這般地進行滑動。換言之，利用控制裝置20所執行的控制，驅動裝置5就可以將被固定在內筒7外側的線圈彈簧3予以拉伸及壓縮。 在本說明書中，雖然是如圖3所示般地，對於各單元10分別設置有三個驅動裝置5，但是，驅動裝置5的個數並不限於此，只要配合設計上的需求，在各單元10設置有一個以上的驅動裝置5即可。 The driving device 5 can be a device such as a pneumatic cylinder provided with a cylinder body provided with a piston inside and a drive rod integrated with the piston. The front end of the driving rod is fixed to the flat plate portion 72 . Therefore, the driving device 5 uses the pneumatic cylinder to push the driving rod out or pull it back, so that the inner cylinder 7 can be pushed out or pulled back along the axis L direction (the flow direction of the treated liquid W1). to swipe. In other words, the driving device 5 can stretch and compress the coil spring 3 fixed outside the inner cylinder 7 by the control performed by the control device 20 . In this specification, although as shown in Figure 3, three driving devices 5 are respectively provided for each unit 10, but the number of driving devices 5 is not limited to this, as long as it meets the design requirements, each unit 10 is provided with more than one driving device 5.
在穿透液排出管14中設置了用來測定通過穿透液排出管14之穿透液PW的流量，且將測定值傳送到控制裝置20的流量計23。在圖1所示的過濾篩裝置1中，連接於三個外筒4之穿透液排出管14的匯流管14b之中，是將流量計23設置在：從三個單元10排出之所有的穿透液PW匯流在一起之後一起流動的地方。 又，在過濾篩裝置1中設置了：被配置在第一衝孔金屬板2A的內側，用來將感測到的被處理液的壓力傳送到第一壓力計21之第一壓力感測器21A；用來將來自第一壓力感測器21A的壓力訊息進行運算後，將第一壓力值P1(量測值)傳送到控制裝置20之第一壓力計21；被配置在第一線圈彈簧3A的外側且是在第一外筒4A的內側，用來將感測到的穿透液的壓力傳送到第二壓力計22之第二壓力感測器22A；用來將來自第二壓力感測器22A的壓力訊息進行運算後，將第二壓力值P2(量測值)傳送到控制裝置20之第二壓力計22。 A flow meter 23 for measuring the flow rate of the penetrating liquid PW passing through the penetrating liquid discharging pipe 14 and transmitting the measured value to the control device 20 is provided in the penetrating liquid discharging pipe 14 . In the filter screen device 1 shown in FIG. 1 , in the confluence pipe 14 b connected to the penetrating liquid discharge pipe 14 of the three outer cylinders 4 , the flowmeter 23 is arranged in: all the liquids discharged from the three units 10 The place where the penetrating fluid PW joins together and then flows together. In addition, the filter screen device 1 is provided with: a first pressure sensor configured inside the first punched metal plate 2A for transmitting the sensed pressure of the liquid to be treated to the first pressure gauge 21 21A; used to calculate the pressure information from the first pressure sensor 21A, and transmit the first pressure value P1 (measured value) to the first pressure gauge 21 of the control device 20; it is arranged on the first coil spring The outer side of 3A and the inner side of the first outer cylinder 4A are used to transmit the sensed pressure of the penetrating fluid to the second pressure sensor 22A of the second pressure gauge 22; After calculating the pressure information of the measuring device 22A, the second pressure value P2 (measured value) is sent to the second pressure gauge 22 of the control device 20 .
在衝孔金屬板2及線圈彈簧3並未發生堵塞的正常運轉時，控制裝置20對於各驅動裝置5的控制方式，係將各單元10之線圈彈簧3的開口(間隙G)控制成保持一定大小。如此一來，過濾篩裝置1就實施與目的相應之被處理液W1的處理(固液分離或濃縮)。When the punched metal plate 2 and the coil spring 3 are not blocked during normal operation, the control method of the control device 20 for each driving device 5 is to control the opening (gap G) of the coil spring 3 of each unit 10 to be kept constant. size. In this way, the filter device 1 performs treatment (solid-liquid separation or concentration) of the liquid to be treated W1 according to the purpose.
又，如果流量計23所量測到的流量低於第一閾值Q的話，或者，第一壓力計21所量測到的第一壓力值P1減去第二壓力計22所量測到的第二壓力值P2之壓力差值ΔP(=P1-P2)大於等於第二閾值P的話，控制裝置20就判斷為線圈彈簧3的堵塞已經變多，乃實施對於夾雜物T的切斷動作。 換言之，如果穿透液PW的流量少於第一閾值Q的話，或者，在第一衝孔金屬板2A之內側的壓力大於在第一線圈彈簧3A的外側且在第一外筒4A之內側的壓力，並且壓力差值大於等於第二閾值P的話，就實施：將卡止於線圈彈簧3的線材6之間而發生堵塞的夾雜物T予以切斷的動作。 Also, if the flow measured by the flow meter 23 is lower than the first threshold Q, or the first pressure value P1 measured by the first pressure gauge 21 minus the first pressure value P1 measured by the second pressure gauge 22 If the pressure difference ΔP (=P1-P2) between the two pressure values P2 is greater than or equal to the second threshold value P, the control device 20 judges that the blockage of the coil spring 3 has increased, and implements a cutting action on the inclusion T. In other words, if the flow rate of the penetrating liquid PW is less than the first threshold Q, or the pressure inside the first punched metal plate 2A is greater than that outside the first coil spring 3A and inside the first outer cylinder 4A pressure, and if the pressure difference is greater than or equal to the second threshold P, the action of cutting off the inclusions T that are stuck between the wires 6 of the coil spring 3 and blocked.
具體而言，控制裝置20係控制驅動裝置5將驅動桿拉回去，而使得內筒7往被處理液W1的上游側進行滑動，藉此，來將線圈彈簧3進行壓縮。更詳細地說，控制裝置20係分別控制第一驅動裝置5A、第二驅動裝置5B及第三驅動裝置5C，來將第一線圈彈簧3A、第二線圈彈簧3B及第三線圈彈簧3C分別進行壓縮。如此一來，利用線材6的第一面61與第二面62所形成的刀口形狀之稜線R，在第一線圈彈簧3A、第二線圈彈簧3B及第三線圈彈簧3C中，分別將夾雜物T予以切斷。此外，控制裝置20也可以實施：反覆地使線圈彈簧3進行伸縮來將夾雜物T予以切斷的動作。 控制裝置20在結束了將夾雜物T予以切斷的動作後，將線圈彈簧3恢復到進行切斷動作前的狀態。換言之，控制各驅動裝置5來將驅動桿推出，來使得線圈彈簧3被拉伸張開且將各單元10之線圈彈簧3的開口寬度保持一定。 此外，控制裝置20在實施了夾雜物T的切斷動作後，也可以實施從清洗液供給裝置30供給清洗液CW來進行逆洗動作。 Specifically, the control device 20 controls the driving device 5 to pull the driving rod back, so that the inner cylinder 7 slides toward the upstream side of the treated liquid W1, thereby compressing the coil spring 3 . More specifically, the control device 20 controls the first drive device 5A, the second drive device 5B, and the third drive device 5C, respectively, so as to move the first coil spring 3A, the second coil spring 3B, and the third coil spring 3C respectively. compression. In this way, the first coil spring 3A, the second coil spring 3B, and the third coil spring 3C respectively move the inclusions by using the knife-edge-shaped ridge line R formed by the first surface 61 and the second surface 62 of the wire 6 . T is cut off. In addition, the control device 20 may perform an operation of repeatedly expanding and contracting the coil spring 3 to cut the inclusion T. After the control device 20 completes the operation of cutting the inclusions T, the coil spring 3 is returned to the state before the cutting operation. In other words, each driving device 5 is controlled to push out the driving rod, so that the coil spring 3 is stretched and the opening width of the coil spring 3 of each unit 10 is kept constant. In addition, the control device 20 may perform the backwashing operation by supplying the cleaning liquid CW from the cleaning liquid supply device 30 after performing the cutting operation of the foreign matter T.
控制裝置20，可以是在：根據流量計23的量測值所做的判定；和根據兩個壓力計21、22的量測值所做的判定之其中一方的判定顯示為堵塞的情況下，就進行逆洗動作，也可以是在：兩種判定都顯示為堵塞的情況下，才進行逆洗動作。如果是前者的情況，係可以將未被使用於判定的流量計23或壓力計21、22予以省略。 此外，在本實施方式中，是在位於最上游的第一單元10A，配置了兩個壓力感測器(第一壓力感測器21A、第二壓力感測器22A)及與其對應的壓力計(第一壓力計21、第二壓力計22)，來對於串聯之所有的單元10的線圈彈簧3都一起同時進行控制彈簧的伸縮。但是，也可以是：在複數個或全部的單元10中，分別都同樣地配置兩個壓力感測器及與其對應的壓力計，而控制裝置20則是因應所量測到的壓力值，來對於設置了該壓力感測器及壓力計之單元10的線圈彈簧3，個別地進行控制彈簧的伸縮。 The control device 20 may be under the condition that: the judgment made according to the measurement value of the flowmeter 23; The backwashing action may be performed, or the backwashing action may be performed only when the two kinds of judgments show that it is clogged. In the former case, the flowmeter 23 or the pressure gauges 21 and 22 that are not used for determination can be omitted. In addition, in this embodiment, two pressure sensors (first pressure sensor 21A, second pressure sensor 22A) and corresponding pressure gauges are arranged in the first unit 10A located most upstream. (the first pressure gauge 21, the second pressure gauge 22), to control the expansion and contraction of the springs simultaneously for the coil springs 3 of all the units 10 connected in series. However, it is also possible that in a plurality or all of the units 10, two pressure sensors and corresponding pressure gauges are similarly configured respectively, and the control device 20 responds to the measured pressure values to The expansion and contraction of the springs are controlled individually for the coil springs 3 of the unit 10 provided with the pressure sensor and the pressure gauge.
[2. 作用及效果] 根據過濾篩裝置1，當線圈彈簧3的線材6之間發生了夾雜物T堵塞時，可以藉由以第一面61和第二面62來形成刀口形狀之線材6的稜線R來將夾雜物T予以切斷，因此，能夠有效地解除線圈彈簧3的堵塞。 [2. Function and effect] According to the filter screen device 1, when the inclusions T are blocked between the wires 6 of the coil spring 3, the inclusions can be removed by forming the ridge line R of the knife-edge-shaped wire 6 with the first surface 61 and the second surface 62. Since T is cut off, clogging of the coil spring 3 can be effectively released.
又，即使過濾篩裝置1是被橫置設置的情況下，也因為在線圈彈簧3的內側設置了衝孔金屬板2，所以衝孔金屬板2可以發揮作為中心棒的作用，不會讓線圈彈簧3撓曲。因此，可以將線圈彈簧3的開口寬度控制成保持一定。即使過濾篩裝置1的軸線L對於水平方向傾斜了α角度的情況下，還是可以獲得同樣的效果。Also, even if the filter screen device 1 is horizontally installed, because the punched metal plate 2 is provided inside the coil spring 3, the punched metal plate 2 can function as a center rod, and the coil will not Spring 3 deflects. Therefore, the opening width of the coil spring 3 can be controlled to be constant. Even if the axis L of the sieve device 1 is inclined by an angle α with respect to the horizontal direction, the same effect can be obtained.
此外，在過濾篩裝置1中，是從被處理液W1的上游至下游，依序地連接著內徑較大的衝孔金屬板2與內徑較小的衝孔金屬板2，因此，讓被處理液W1通過之衝孔金屬板2的剖面積(與軸線L正交之剖面的面積)是隨著水流方向依序地變小。如此一來，在上游側的單元10(例如：第一單元10A)中沒有與衝孔金屬板2的壁面發生接觸就直接往下游流動之流經軸線L附近的被處理液W1，係可以在較諸上游側的衝孔金屬板2的剖面積更小之下游側的衝孔金屬板2中，更容易與壁面發生接觸。因而得以提高過濾效率。In addition, in the filter screen device 1, from the upstream to the downstream of the liquid to be treated W1, the punched metal plate 2 with a larger inner diameter and the punched metal plate 2 with a smaller inner diameter are sequentially connected. The cross-sectional area (area of the cross-section perpendicular to the axis L) of the punched metal plate 2 through which the treated liquid W1 passes decreases sequentially with the flow direction. In this way, in the unit 10 on the upstream side (for example: the first unit 10A), the liquid W1 to be treated that flows directly downstream without contacting the wall surface of the punched metal plate 2 can be obtained in the vicinity of the axis L. The punched metal plate 2 on the downstream side has a smaller cross-sectional area than the punched metal plate 2 on the upstream side, and it is easier to come into contact with the wall surface. Thus, the filtration efficiency can be improved.
此外，在過濾篩裝置1中，無需設置習知技術的那種具備多數個搖擺片的旋轉軸，就可以達成上述的效果，因此，可以較低的成本來製造。 因此，根據過濾篩裝置1，即使是橫置設置的情況下，也能夠讓彈簧的開口寬度保持一致，且加大與濾材體也就是衝孔金屬板2的壁面發生接觸之被處理液W1的流量，並且又可以較低的成本來製造該裝置。 In addition, in the filter screen device 1, the above-mentioned effect can be achieved without installing a rotating shaft with a plurality of wobbling pieces in the prior art, so it can be manufactured at a relatively low cost. Therefore, according to the filter screen device 1, even when it is horizontally installed, the opening width of the spring can be kept uniform, and the thickness of the treated liquid W1 that contacts the wall surface of the filter material body, that is, the punched metal plate 2 can be increased. flow, and the device can be manufactured at a lower cost.
如果流量計23所量測到的流量低於第一閾值Q的話，或者，如果第一壓力值P1減去第二壓力值P2的壓力差值ΔP大於等於第二閾值P的話，控制裝置20就控制各驅動裝置5來將發生堵塞的夾雜物T予以切斷。是以這種方式利用流量計23或壓力計21、22來判定線圈彈簧3的堵塞程度，因此，可以較低的成本且確實地解除線圈彈簧3的堵塞。If the flow measured by the flow meter 23 is lower than the first threshold Q, or if the pressure difference ΔP obtained by subtracting the second pressure P2 from the first pressure P1 is greater than or equal to the second threshold P, the control device 20 will Each driving device 5 is controlled to cut off the clogged inclusions T. In this way, the degree of clogging of the coil spring 3 is judged by the flow meter 23 or the pressure gauges 21 and 22 , so that the clogging of the coil spring 3 can be reliably released at low cost.
[3. 變形例] 上述的過濾篩裝置1只是其中一例而已，本發明的結構不限於上述的例子。 圖4是變形例的過濾篩裝置1’所具備之衝孔金屬板2及線圈彈簧3的局部剖面立體圖。這種過濾篩裝置1’與上述的過濾篩裝置1相較的差異點是在於：在各單元10的至少其中之一，設置了用來增加與衝孔金屬板2發生接觸之被處理液W1的流量之旋轉裝置8，而其他的結構都是同樣的。 [3. Variations] The above-mentioned filter screen device 1 is just one example, and the structure of the present invention is not limited to the above-mentioned examples. Fig. 4 is a partially sectional perspective view of a punched metal plate 2 and a coil spring 3 included in a filter device 1' according to a modified example. The difference between this filter screen device 1' and the above-mentioned filter screen device 1 is that: in at least one of the units 10, a treatment liquid W1 used to increase the contact with the punched metal plate 2 is provided. The rotating device 8 of the flow rate, and other structures are all the same.
旋轉裝置8，係如圖4所示般地，無論是被配置在哪一個單元10之衝孔金屬板2的內部皆可，也可以是被配置在所有的單元10之衝孔金屬板2的內部。旋轉裝置8係具備：與軸線L同一軸心的旋轉軸81、以及往上游側逐漸變窄且下游端為圓角頭之氣球型的旋轉體82。The rotating device 8, as shown in FIG. 4, may be arranged inside the punched metal plate 2 of any unit 10, or may be arranged in the punched metal plate 2 of all the units 10. internal. The rotating device 8 includes: a rotating shaft 81 having the same axis as the axis L, and a balloon-shaped rotating body 82 that gradually narrows toward the upstream side and has a rounded head at the downstream end.
旋轉軸81是被配置成：與衝孔金屬板2的軸線L同一軸心，並且利用例如：被固定在衝孔金屬板2的內部之支承構件(未圖示)而被支承成能夠進行旋轉。支承構件可以是具有：可以使旋轉軸81沿著軸線L的方向進行滑動的功能。旋轉體82的上游端(後述的前端部83)是被固定在旋轉軸81的下游端。又，亦可在旋轉軸81的上游側設置了馬達(電動機)87。The rotating shaft 81 is arranged so as to be coaxial with the axis L of the punched metal plate 2, and is rotatably supported by, for example, a support member (not shown) fixed inside the punched metal plate 2. . The support member may have a function of allowing the rotation shaft 81 to slide in the axis L direction. The upstream end of the rotating body 82 (the front end portion 83 described later) is fixed to the downstream end of the rotating shaft 81 . In addition, a motor (electric motor) 87 may be provided on the upstream side of the rotating shaft 81 .
旋轉體82可以大致上區分為三個部分，也就是：被形成略呈圓柱形的中間部85；位於中間部85的上游側從被處理液W1的上游往下游逐漸朝徑向擴徑之呈逐漸擴徑形狀的前端部83；以及位於中間部85的下游側從被處理液W1的上游往下游形成逐漸朝徑向縮徑(徑向尺寸變小)形狀的末端部84。中間部85的外徑小於衝孔金屬板2的內徑。 被處理液W1是從旋轉體82的前端部83朝中間部85流動，如此一來，將會流入位於中間部85與衝孔金屬板2之間的狹窄流路，而很有效率地與衝孔金屬板2的壁面進行接觸。因此，可以提高濾材體也就是衝孔金屬板2及線圈彈簧3的過濾效率。 在中間部85的外周面固定著四片整流翼86，該整流翼86是呈螺旋形地延伸在被處理液W1之流動方向的整個範圍。 The rotating body 82 can be roughly divided into three parts, that is: a middle part 85 formed into a slightly cylindrical shape; the upstream side of the middle part 85 gradually expands in diameter from the upstream to the downstream of the treated liquid W1. The front end portion 83 with a gradually expanding diameter; and the terminal portion 84 with a gradually radially decreasing diameter (dimension in the radial direction) formed on the downstream side of the middle portion 85 from upstream to downstream of the liquid to be treated W1. The outer diameter of the intermediate portion 85 is smaller than the inner diameter of the punched metal plate 2 . The liquid W1 to be treated flows from the front end 83 of the rotating body 82 toward the middle part 85. In this way, it will flow into the narrow flow path between the middle part 85 and the punched metal plate 2, and efficiently interact with the punched metal plate 2. The wall surface of the perforated metal plate 2 is in contact. Therefore, the filtration efficiency of the filter body, that is, the punched metal plate 2 and the coil spring 3 can be improved. Four straightening vanes 86 are fixed to the outer peripheral surface of the intermediate portion 85, and the straightening vanes 86 extend spirally over the entire range of the flow direction of the liquid to be treated W1.
被供給到過濾篩裝置1’的被處理液W1將會流過中間部85與衝孔金屬板2之間的空間。此時，將會有以軸線L為中心進行旋轉的力量作用在整流翼86身上，如此一來，旋轉裝置8將會進行旋轉。換言之，藉由被處理液W1的流動，無需動力就可以讓旋轉裝置8以軸線L為中心進行旋轉。The liquid to be treated W1 supplied to the filter screen device 1' flows through the space between the intermediate portion 85 and the punched metal plate 2. As shown in FIG. At this time, there will be a rotating force around the axis L acting on the rectifying vane 86 , so that the rotating device 8 will rotate. In other words, the rotation device 8 can be rotated around the axis L by the flow of the liquid to be treated W1 without power.
藉由旋轉裝置8的旋轉，被處理液W1受到攪拌而能夠使得被處理液W1與衝孔金屬板2的壁面進行接觸。又，流經過整流翼86的周邊的被處理液W1將會被整流翼86推擠而通過衝孔金屬板2的孔h往徑向外側的空間推擠出去。如此一來，可以促進線圈彈簧3對於被處理液W1的分離作用而可更加提高過濾效率。By the rotation of the rotating device 8 , the liquid to be treated W1 is stirred and the liquid to be treated W1 can be brought into contact with the wall surface of the punched metal plate 2 . Furthermore, the liquid W1 to be treated flowing through the periphery of the straightening vane 86 will be pushed by the straightening vane 86 and pushed out to the radially outer space through the hole h of the punched metal plate 2 . In this way, the separation effect of the coil spring 3 on the liquid to be treated W1 can be promoted, and the filtration efficiency can be further improved.
也可以讓被設置在旋轉軸81之上游側的馬達87具有剎車動能回充的作用，藉以調整旋轉軸81的旋轉速度。如此一來，可以更適當地實施被處理液W1的分離。藉由剎車動能回充作用所發電的電力可以用來作為設在過濾篩裝置1’的外部之照明燈具的電力，如此一來，對於設置有該過濾篩裝置1’之設備的省電化也有幫助。旋轉裝置8也可以是具有：藉由使得旋轉軸81沿著軸線L進行滑動來調整過濾效率的功能。The motor 87 arranged upstream of the rotating shaft 81 can also be used to recharge the braking kinetic energy, so as to adjust the rotational speed of the rotating shaft 81 . In this way, the separation of the liquid to be treated W1 can be performed more appropriately. The electric power generated by the brake kinetic energy recharging can be used as the power of the lighting fixtures installed outside the filter device 1', so that it is also helpful for the power saving of the equipment equipped with the filter device 1' . The rotating device 8 may also have the function of adjusting the filtration efficiency by sliding the rotating shaft 81 along the axis L. As shown in FIG.
也可以在前端部83的外周面形成有：用來將被處理液攪動成亂流之複數個凹凸形狀。利用該凹凸形狀，可以抑制流動在軸線L的附近之被處理液沒有與衝孔金屬板2發生接觸就直接往下游流過去的現象，因此，可以更加提高過濾效率。A plurality of concavo-convex shapes for stirring the liquid to be treated into a turbulent flow may be formed on the outer peripheral surface of the front end portion 83 . The concave-convex shape prevents the liquid to be treated flowing near the axis L from directly flowing downstream without contacting the punched metal plate 2, thereby further improving the filtration efficiency.
根據變形例的過濾篩裝置1’，係利用與衝孔金屬板2同一軸心的旋轉軸81以及具有整流翼86的旋轉體82之簡易的結構的旋轉裝置8，就可以增加與衝孔金屬板2的壁面接觸之被處理液W1的流量。換言之，無需採用如專利文獻2所示的那種在旋轉軸設置了多數個搖擺片之複雜的結構，就可以增加與衝孔金屬板2的壁面接觸之被處理液W1的流量，因此，能夠提供只要較低成本即可製造的過濾篩裝置1’。 又，旋轉裝置8即使沒有馬達87，也可以利用被處理液W1的流動，無需動力即可以軸線L為中心進行旋轉，因此，不必設置用來使旋轉裝置8進行旋轉的裝置，也可以省略用來配置該裝置的工序。藉此，也能夠提供只要較低成本即可製造的過濾篩裝置1’。 According to the filter screen device 1' of the modified example, the rotation device 8 with the simple structure of the rotating shaft 81 with the same axial center as the punching metal plate 2 and the rotating body 82 with the rectifying vanes 86 can be added to the punching metal plate. The flow rate of the treated liquid W1 that the wall surface of the plate 2 contacts. In other words, it is possible to increase the flow rate of the treated liquid W1 in contact with the wall surface of the punched metal plate 2 without adopting a complicated structure in which a plurality of swinging pieces are provided on the rotating shaft as shown in Patent Document 2, and therefore, it is possible to A filter screen device 1' is provided which can be manufactured at relatively low cost. Moreover, even if the rotating device 8 does not have the motor 87, it can utilize the flow of the liquid to be treated W1 to rotate around the axis L without power. To configure the process of the device. Thereby, it is also possible to provide a sieve device 1' which can be manufactured at relatively low cost.
圖5是另外一種變形例的過濾篩裝置1”所具備的衝孔金屬板2及線圈彈簧3之局部剖面立體圖。這種過濾篩裝置1”與圖4的過濾篩裝置1’相較的差異點是在於：旋轉裝置8之旋轉體82的形狀而已。過濾篩裝置1”之其他的結構都是與過濾篩裝置1’同樣，因此，省略其說明。 如圖5所示般地，旋轉裝置8’係具備：與圖4的旋轉裝置8所具備的旋轉軸81同樣的旋轉軸81’、以及具備了前端部83及具有整流翼86的中間部85之子彈形狀的旋轉體82’。旋轉體82’係不具有：相當於旋轉體82中的末端部84的部分。即使是在這種形狀的旋轉裝置8’中，還是可以獲得與上述的旋轉裝置8同樣的效果。 Fig. 5 is a partial sectional perspective view of a punched metal plate 2 and a coil spring 3 provided by another modified filter screen device 1". The difference between this filter screen device 1" and the filter screen device 1' of Fig. 4 The point is: the shape of the rotating body 82 of the rotating device 8 . The other structures of the sieve device 1" are the same as the sieve device 1', so description thereof will be omitted. As shown in FIG. 5, the rotating device 8' is provided with a rotating shaft 81' similar to the rotating shaft 81 provided in the rotating device 8 of FIG. The bullet-shaped rotating body 82'. The rotating body 82' does not have: a portion corresponding to the terminal portion 84 of the rotating body 82. Even in the rotating device 8' having such a shape, the same effect as that of the rotating device 8 described above can be obtained.
