Description

本開示は、スクリーン装置及び処理システムに関する。   The present disclosure relates to screen devices and processing systems.

固液分離や分級など、各種の用途で用いられるスクリーン装置には、被処理物に含まれる所定の大きさ以上の物質の通過を妨げ且つ当該所定の大きさ未満の物質を通過させ、又は、所定量の被処理物を通過させる目開き（隣接する線材の間隔、隙間）が形成されている。そして、スクリーン装置においては、当該目開きの大きさが固定の装置のみならず、当該目開きの大きさを可変とする装置が開発されている。   For screen devices used in various applications such as solid-liquid separation and classification, passing a substance having a size smaller than or equal to a predetermined size contained in the object to be processed and a substance having a size smaller than the predetermined size, or Openings (intervals between adjacent wire rods, gaps) for passing a predetermined amount of the object to be processed are formed. As for the screen device, not only a device having a fixed size of the openings, but also a device having a variable size of the openings has been developed.

例えば、特許文献１には、固定側ふるい部材と、固定側ふるい部材に対して摺動可能な可動側ふるい部材とを備え、可動側ふるい部材を摺動することで、目開きの大きさを変化させることができる装置が開示されている。   For example, in Patent Document 1, a fixed-side sieving member and a movable-side sieving member that is slidable with respect to the fixed-side sieving member are provided, and by sliding the movable-side sieving member, the size of the openings can be increased. Devices that can be varied are disclosed.

また、特許文献２には、線材を螺旋状に巻いたコイルバネを引き伸ばすことで、隣り合う線材の間隔を拡大することができる、すなわち目開きの大きさを変化させることができる装置が開示されている。   Further, Patent Document 2 discloses a device capable of expanding the distance between adjacent wire rods, that is, changing the size of the openings by stretching a coil spring formed by winding a wire rod in a spiral shape. There is.

以下、添付図面を参照して、本発明のスクリーン装置及び当該スクリーン装置を用いた処理システムの実施形態を説明する。   Embodiments of a screen device of the present invention and a processing system using the screen device will be described below with reference to the accompanying drawings.

＜第一実施形態＞（第一のスライド部を備えた平板状のスクリーン装置）
第一実施形態のスクリーン装置１Ａについて、図１〜図５を参照して説明する。なお、以下、各図に示したｘｙｚ直交座標系を用いて説明する。当該説明においては、ｘ軸の方向を「ｘ方向」、ｙ軸の方向を「ｙ方向」、ｚ軸の方向を「ｚ方向」という。また、図１〜図５では、ｚ方向を鉛直方向としており、ｚ軸の矢印の向く方向が上方へ向かう方向（重力の働く方向と逆の方向）である。 <First embodiment> (a flat screen device including a first slide portion)
The screen device 1A of the first embodiment will be described with reference to FIGS. 1 to 5. In the following, description will be made using the xyz orthogonal coordinate system shown in each drawing. In the description, the x-axis direction is referred to as “x direction”, the y-axis direction is referred to as “y direction”, and the z-axis direction is referred to as “z direction”. 1 to 5, the z direction is the vertical direction, and the direction of the arrow on the z axis is the upward direction (the direction opposite to the direction in which gravity acts).

スクリーン装置１Ａは、例えばウェッジワイヤのような直線状の線材２を「すのこ」のように同一平面上に規則的に複数並べた平板状の形状である。ここでは、ｙ方向を各線材２の長さ方向とし、各線材２の中心軸Ｃが互いに平行になるようｘ方向に規則的に並べた構成としている。なお、複数の線材２のうち、隣り合う２つの線材２の一方を第一の線材２ａ、他方を第二の線材２ｂという。
第一の線材２ａと第二の線材２ｂは、互いの中心軸Ｃをｘ方向に所定距離だけ離し、隙間が形成されるように配置される。第一の線材２ａと第二の線材２ｂの各々の中心軸Ｃのｘ方向の当該所定距離は、用途に応じて設定される。図１〜図３及び図５では、隣り合う線材２同士が接触し、隙間がないように見える。しかし、ここでは、数ｍｍという微小な隙間の例を図示したため、このように見えるにすぎない。実際には、隣り合う線材２同士は、後述の例外を除き、原則として互いに接触していない。
線材２は、平らな面であるスクリーン面Ｓを備えている。各線材２のスクリーン面Ｓは、互いにｚ方向にずれないよう、それぞれ同一平面上に配置される。各線材２のスクリーン面Ｓが互いにｚ方向にずれないように各線材２の移動を制限するため、例えば、板状の移動制限部３が、各線材２に跨って配置される。
なお、ここでは、スクリーン面Ｓのｚ方向上方に移動制限部３が配置されているが、各線材２のｚ方向下方にも図示しない移動制限部３が配置される。すなわち、２つの移動制限部３で各線材２をｚ方向の上下から挟み込むことで、各線材２のｚ方向への移動を制限することができる。また、図示しないが、移動制限部３は、各線材２の両端付近にそれぞれ少なくとも１つづつ（ｚ方向上方と下方で線材を挟み込む場合は、それぞれ少なくとも２つづつ）配置することが望ましい。
各線材２のそれぞれの一方の端部（以下、「一端」という）は、ｘ方向に伸縮可能な係止部４（第一の係止部４ａ）で接続されており、それぞれの他方の端部（以下、「他端」という）は、ｘ方向に伸縮可能な係止部４（第二の係止部４ｂ）で接続されている。このため、各線材２のｘ方向への移動も制限することができる。なお、線材２は、一端から他端まで同一面積であってもよいし、一端から他端、または、他端から一端に向かって先細る形状であってもよい。 The screen device 1A has a flat plate shape in which a plurality of linear wire rods 2 such as wedge wires are regularly arranged on the same plane like a “slat”. Here, the y direction is the length direction of each wire 2, and the wires 2 are regularly arranged in the x direction so that the central axes C of the wires 2 are parallel to each other. Of the plurality of wire rods 2, one of the two adjacent wire rods 2 is referred to as a first wire rod 2a and the other is referred to as a second wire rod 2b.
The first wire 2a and the second wire 2b are arranged such that their central axes C are separated from each other by a predetermined distance in the x direction and a gap is formed. The predetermined distance in the x direction of the central axis C of each of the first wire 2a and the second wire 2b is set according to the application. In FIGS. 1 to 3 and 5, the adjacent wire rods 2 are in contact with each other, and it seems that there is no gap. However, here, since an example of a minute gap of several mm is illustrated, it only looks like this. In practice, the adjacent wire rods 2 do not, as a general rule, contact each other with the exceptions described below.
The wire 2 has a screen surface S which is a flat surface. The screen surfaces S of the wire rods 2 are arranged on the same plane so as not to shift in the z direction. In order to restrict the movement of the wire rods 2 so that the screen surfaces S of the wire rods 2 do not shift in the z-direction, for example, a plate-shaped movement limiting portion 3 is arranged across the wire rods 2.
Although the movement restricting portion 3 is arranged above the screen surface S in the z direction here, the movement restricting portion 3 (not shown) is also arranged below the respective wire rods 2 in the z direction. That is, the movement of each wire rod 2 in the z direction can be restricted by sandwiching each wire rod 2 from above and below in the z direction by the two movement restricting portions 3. Further, although not shown, it is desirable that at least one movement restricting portion 3 is disposed near each end of each wire rod 2 (at least two each when the wire rod is sandwiched above and below in the z direction).
One end (hereinafter, referred to as “one end”) of each wire 2 is connected by a locking portion 4 (first locking portion 4a) that can expand and contract in the x direction, and the other end of each is connected. The parts (hereinafter, referred to as “the other end”) are connected by a locking part 4 (second locking part 4b) that can expand and contract in the x direction. Therefore, the movement of each wire 2 in the x direction can also be restricted. The wire 2 may have the same area from one end to the other end, or may have a shape that tapers from one end to the other end or from the other end to the one end.

ここでは、線材２は、ウェッジワイヤであるとして話を進める。ウェッジワイヤには、中心軸Ｃに直交する断面形状が台形、半円形、三角形などの種類が存在する。断面形状に平らな部分が存在するウェッジワイヤであれば、当該平らな部分をスクリーン面Ｓとすることで、本実施形態に使用可能である。
本実施形態では、線材２として、当該断面形状が三角形のウェッジワイヤを使用した例を示す。三角形の一辺をスクリーン面Ｓに使用するので、スクリーン面Ｓからｚ方向（スクリーン面Ｓに対する垂直方向）の下方に離れるにしたがって、線材２は次第に細くなる。 Here, the wire 2 will be described as a wedge wire. There are various types of wedge wires whose cross-sectional shape orthogonal to the central axis C is trapezoidal, semicircular, triangular, or the like. If the wedge wire has a flat portion in the cross-sectional shape, it can be used in this embodiment by setting the flat portion as the screen surface S.
In the present embodiment, an example in which a wedge wire having a triangular cross section is used as the wire rod 2 is shown. Since one side of the triangle is used for the screen surface S, the wire rod 2 becomes gradually thinner as it goes away from the screen surface S in the z direction (the direction perpendicular to the screen surface S).

係止部４（第一の係止部４ａ、第二の係止部４ｂ）は、第一の線材２ａと第二の線材２ｂの各々の一端または各々の他端を接続する弾性体（バネ、ゴム、等）でもよいが、ここでは、リンク機構で構成された例を示す。なお、第一の係止部４ａと第二の係止部４ｂは同一の構成としてもよいし、一方がリンク機構で他方が弾性体であるなど、互いに異なる構成としてもよい。   The locking portion 4 (first locking portion 4a, second locking portion 4b) is an elastic body (spring) that connects one end or the other end of each of the first wire 2a and the second wire 2b. , Rubber, etc.), but here, an example constituted by a link mechanism is shown. The first locking portion 4a and the second locking portion 4b may have the same configuration, or may have different configurations such as one having a link mechanism and the other having an elastic body.

リンク機構は、互いに隣り合う線材２同士を連結する二本一対のリンクアーム４１を有する。リンクアーム４１の一方の端部同士は、第一連結ピン４１ａによって回動自在に連結される。リンクアーム４１の他方の端部は、それぞれ、隣り合う線材２の各々の端部に第二連結ピン４１ｂによって回動自在に連結される。また、図１〜図３には紙面の都合で図示していないが、図４に示すように、上記二本一対のリンクアーム４１同士は、弾性体（バネ、ゴム、等）４１ｃで互いに接続されている。弾性体４１ｃは、当該二本のリンクアーム４１が互いに引き合うよう付勢されている。   The link mechanism includes two pairs of link arms 41 that connect the wire rods 2 adjacent to each other. One ends of the link arms 41 are rotatably connected by a first connecting pin 41a. The other end of the link arm 41 is rotatably connected to each end of the adjacent wire rods 2 by a second connecting pin 41b. Although not shown in FIGS. 1 to 3 due to space limitations, as shown in FIG. 4, the pair of link arms 41 are connected to each other by an elastic body (spring, rubber, etc.) 41c. Has been done. The elastic body 41c is urged so that the two link arms 41 attract each other.

制御装置６は、第一の線材２ａ及び第二の線材２ｂを押圧するスライド部を移動させるよう制御することで、隣り合う各線材２のそれぞれの上記「一端」における各中心軸Ｃ同士の距離（以下、「第一の間隔Ｇａ」という）を、上記「他端」における各中心軸Ｃ同士の距離（以下、「第二の間隔Ｇｂ」という）より大きくすることができる。
第一実施形態では、断面が略円形で短い棒状の第一のスライド部５ａを、スライド部の例として示す。
第一のスライド部５ａは、スクリーン装置のｘ方向（幅方向）で互いに隣り合う線材２の間、且つ、線材２のスクリーン面Ｓのｚ方向下方に配置された棒状の部材である。第一のスライド部５ａは、上記「一端」の近傍、例えば、第一の係止部４ａの近傍に配置される。ここでは、第一のスライド部５ａは、各線材２間にそれぞれ１つづつ配置され、且つ、隣り合う線材２に接触して配置されている。各々の第一のスライド部５ａは、後述のように第一の間隔Ｇａが広げられる際、各線材２のｘ方向の移動に伴って、それぞれ別個に独立してｘ方向にスライド可能、且つ、当該棒の軸線がｙ方向からずれることが可能となるよう配置されるのが望ましい。
制御装置６は、第一のスライド部５ａをｚ方向に上下移動させる移動機構、例えば、油圧シリンダや電動シリンダ等を用いた移動機構（図示無し）を備えており、第一のスライド部５ａを、スクリーン面Ｓよりｚ方向の下方且つ所定範囲内で移動させることができる。 The control device 6 controls the first wire rod 2a and the second wire rod 2b to move so as to move the slide portion, so that the distance between the center axes C of the adjacent ones of the wire rods 2 at the "one end". (Hereinafter, referred to as “first gap Ga”) can be made larger than the distance between the central axes C at the above “other ends” (hereinafter referred to as “second gap Gb”).
In the first embodiment, the first slide portion 5a having a substantially circular cross section and a short rod shape is shown as an example of the slide portion.
The first slide portion 5a is a rod-shaped member arranged between the wire rods 2 adjacent to each other in the x direction (width direction) of the screen device and below the screen surface S of the wire rod 2 in the z direction. The first slide portion 5a is arranged near the "one end", for example, near the first locking portion 4a. Here, the 1st slide part 5a is arrange | positioned one by one between each wire rod 2, and is arrange | positioned in contact with the adjacent wire rod 2. When the first gap Ga is widened as will be described later, each of the first slide portions 5a is individually and independently slidable in the x direction with the movement of each wire rod 2 in the x direction, and It is desirable to arrange the axis of the rod so that it can be displaced from the y direction.
The control device 6 includes a moving mechanism (not shown) that moves the first slide portion 5a up and down in the z direction, for example, a moving mechanism (not shown) that uses a hydraulic cylinder, an electric cylinder, or the like. , Can be moved below the screen surface S in the z direction and within a predetermined range.

制御装置６が、第一のスライド部５ａをスクリーン面Ｓに向かって移動させることで、第一の線材２ａと第二の線材２ｂの両方に接触した第一のスライド部５ａは、当該接触した箇所における第一の線材２ａと第二の線材２ｂの間隔をｘ方向（スクリーン装置の幅方向）に押圧して広げることができる。上述のように、ここでは、第一の線材２ａと第二の線材２ｂは断面が三角形のウェッジワイヤであるので、第一のスライド部５ａがスクリーン面Ｓに向かうほど、線形的に当該間隔がｘ方向に広がることになる。具体的には、図４の例では、第一の線材２ａが＋ｘ方向（プラスｘ方向、すなわちｘ軸上の正方向）に移動し、第二の線材２ｂが-−ｘ方向（マイナスｘ方向、すなわちｘ軸上の負方向）に移動する。このとき、移動制限部３により、第一の線材２ａと第二の線材２ｂがｚ方向に移動することはない。
このように、制御装置６が第一の線材２ａと第二の線材２ｂの間隔を広げるよう制御することで、第一の間隔Ｇａを、第二の間隔Ｇｂより大きくすることができる。
なお、図５に示すように、当該制御前においては、第一の間隔Ｇａと第二の間隔Ｇｂはいずれも上記所定距離であり、第一の線材２ａと第二の線材２ｂは、原則として互いに接触していない。しかし、第一の間隔Ｇａが広がることで、第二の間隔Ｇｂが当該所定距離より狭くなる場合がありうる。このため、例外として、第一の線材２ａと第二の線材２ｂが各々の「他端」において接触する場合がありうる。 The control device 6 moves the first slide portion 5a toward the screen surface S, so that the first slide portion 5a that is in contact with both the first wire 2a and the second wire 2b is in contact therewith. The space between the first wire 2a and the second wire 2b at the location can be widened by pressing in the x direction (width direction of the screen device). As described above, here, since the first wire 2a and the second wire 2b are wedge wires having a triangular cross section, as the first slide portion 5a moves toward the screen surface S, the distance linearly increases. It will spread in the x direction. Specifically, in the example of FIG. 4, the first wire 2a moves in the + x direction (plus x direction, that is, the positive direction on the x axis), and the second wire 2b moves in the −x direction (minus x direction). , Ie, in the negative direction on the x-axis). At this time, the movement restricting unit 3 prevents the first wire 2a and the second wire 2b from moving in the z direction.
In this way, the control device 6 controls the first wire rod 2a and the second wire rod 2b so as to widen the space between them, so that the first space Ga can be made larger than the second space Gb.
In addition, as shown in FIG. 5, before the control, both the first distance Ga and the second distance Gb are the predetermined distances, and the first wire 2a and the second wire 2b are, in principle, Not in contact with each other. However, the second gap Gb may become narrower than the predetermined distance due to the widening of the first gap Ga. Therefore, as an exception, the first wire 2a and the second wire 2b may come into contact with each other at their "other ends".

一方、制御装置６が、第一の線材２ａと第二の線材２ｂの間隔を上述のように一旦広げた後、第一のスライド部５ａをスクリーン面Ｓからｚ方向下方に向かって移動させることで、すなわち、スクリーン面Ｓから遠ざけるように移動させることで、二本のリンクアーム４１が互いに引き合うように弾性体４１ｃが付勢されているので、上記接触した箇所における第一の線材２ａと第二の線材２ｂの各中心軸Ｃの間隔を、上記所定距離までｘ方向に狭めることができる。   On the other hand, the control device 6 temporarily expands the distance between the first wire 2a and the second wire 2b as described above, and then moves the first slide portion 5a downward from the screen surface S in the z direction. That is, since the elastic body 41c is biased so that the two link arms 41 attract each other by moving them away from the screen surface S, the first wire 2a and the first wire 2a at the contact point are The distance between the central axes C of the second wire rods 2b can be narrowed in the x direction to the above-mentioned predetermined distance.

なお、スクリーン装置１Ａを使用する場合、上記「一端」が上記「他端」よりｚ方向の下方となるよう、ｙ方向を水平線より傾けて使用するのが望ましい。スクリーン面Ｓのｚ方向上方から上記「他端」付近のスクリーン面Ｓに被処理物Ｐが供給される。被処理物Ｐの種類に応じて、分級、固液分離、濃縮等、所定の処理が可能となる。   When the screen device 1A is used, it is desirable to use the screen device 1A with the y direction inclined with respect to the horizontal line so that the “one end” is below the “other end” in the z direction. The workpiece P is supplied from above the screen surface S in the z direction to the screen surface S near the "other end". Predetermined treatments such as classification, solid-liquid separation, and concentration can be performed depending on the type of the object P to be treated.

以上の説明においては、断面が略円形で短い棒状の部材を第一のスライド部５ａとして説明したが、当該部材ではなく、上記リンク機構、例えば、第一連結ピン４１ａを第一のスライド部５ａとしてもよい。この場合においても、制御装置６が、第一のスライド部５ａである第一連結ピン４１ａをスクリーン面Ｓに向かって移動させることで、第二連結ピン４１ｂとリンクアーム４１を介して、第一の線材２ａと第二の線材２ｂの間隔をｘ方向（スクリーン装置の幅方向）に押圧して広げることができる。   In the above description, a rod-shaped member having a substantially circular cross section and a short rod shape has been described as the first slide portion 5a. However, instead of the member, the link mechanism, for example, the first connecting pin 41a is used as the first slide portion 5a. May be In this case as well, the control device 6 moves the first connecting pin 41a, which is the first slide portion 5a, toward the screen surface S, so that the first connecting pin 41b and the link arm 41 can be used to move The space between the wire 2a and the second wire 2b can be widened by pressing in the x direction (width direction of the screen device).

以上のように、第一実施形態のスクリーン装置１Ａは、第一のスライド部５ａをｚ方向に移動させるという簡易な構成で、隣り合う線材２の間隔（目開き）の大きさを、図５に示すように、線材２の「他端」から「一端」に向かって、長さ方向に次第に大きくなるよう制御可能である。従って、１つのスクリーン装置のみで、「他端」に供給した被処理物を「一端」に向かうまでに小径物から大径物へと多段階に分級したり、固液分離などの処理をすることができる。よって、スクリーン装置１Ａは、費用対効果の優れたスクリーン装置である。   As described above, the screen device 1A according to the first embodiment has a simple configuration in which the first slide portion 5a is moved in the z direction, and the size of the interval (opening) between the adjacent wire rods 2 is as shown in FIG. As shown in, it is possible to control the wire rod 2 so as to gradually increase in the length direction from the “other end” to the “one end”. Therefore, with only one screen device, the object to be treated supplied to the "other end" is subjected to multi-stage classification from small diameter to large diameter and solid-liquid separation by the time it goes to "one end". be able to. Therefore, the screen device 1A is a cost-effective screen device.

＜第一実施形態の変形例＞（第二のスライド部を備えた平板状のスクリーン装置）
図６〜図８に、第一実施形態の変形例を示す。第一実施形態と同一の部品または装置等は、同一番号を付して、説明を省略する。
当該変形例は、スライド部として、第一のスライド部５ａに代わり、スクリーン面Ｓにｚ方向上方で当接する板状の移動制限部３に、後述する楔部７を複数配置した第二のスライド部５ｂを用いる点で、第一実施形態と異なる。また、制御装置６は、第二のスライド部５ｂをｙ方向に移動させる移動機構、例えば、油圧シリンダや電動シリンダ等を用いた移動機構（図示無し）を備えており、第二のスライド部５ｂを、スクリーン面Ｓに沿って＋ｙ方向（プラスｙ方向、すなわちｙ軸上の正方向）及び−ｙ方向（マイナスｙ方向、すなわちｙ軸上の負方向）に所定範囲内で移動させることができる点においても、第一実施形態と異なる。その他の点は、第一実施形態のスクリーン装置１Ａと同様である。
図８に示すように、楔部７は、ｘｙ平面で見て、二等辺三角形状の楔型に形成されている。楔部７の底辺（ｘ方向の短辺）の長さは、上記所定距離より大きく形成されている。また、底辺の中点と頂角を結ぶ仮想線は、ｙ方向に配置され、且つ、第一の線材２ａと第二の線材２ｂの間隔の中点に配置される。ここでは、一例として、複数の楔部７は、隣り合う複数の線材２の各々の隙間にそれぞれ１つづつ配置している。なお、各々の楔部７は、第一の間隔Ｇａが広げられる際、各線材２のｘ方向の移動に伴って、移動制限部３上で、「カーテンレール」のようにそれぞれ別個に独立してｘ方向にスライド可能、且つ、当該棒の軸線がｙ方向からずれることが可能となるよう構成されるのが望ましい。
ここでは、楔部７は、図６に示すように、ｘｚ平面で見て二等辺三角形状の楔型であり、また、図７に示すように、ｙｚ平面で見て直角三角形状の楔型であるとして話を進める。なお、楔部７は、線材２の断面形状によっては、ｘｚ平面で見て四角形、ｙｚ平面で見て四角形の形状に形成してもよい。
第二のスライド部５ｂは、ｘｙ平面及びｚ方向で見て、楔部７の頂角を第一の線材２ａと第二の線材２ｂの上記一端且つ各々の間に介在して配置される。また、ｙ方向で見て、楔部７の底辺が線材２の外側に配置される。これにより、第一の線材２ａと第二の線材２ｂの各中心軸Ｃのｘ方向の距離を、上記所定距離に設定することができる。
第一の線材２ａと第二の線材２ｂが上記所定距離に配置された状態から第一の間隔Ｇａを第二の間隔Ｇｂより大きくする場合、制御装置６は、第二のスライド部５ｂをスクリーン面Ｓに沿って＋ｙ方向（プラス方向）へ移動する。すると、第一の線材２ａと第二の線材２ｂのｘ方向の間に、楔部７の頂角から底辺が次第に入り込んで第一の線材２ａと第二の線材２ｂをｘ方向に押圧するので、第一の間隔Ｇａを第二の間隔Ｇｂより大きくすることができる。
なお、第二スライド部が使用されるスクリーン装置は、上記一端において、隣り合う線材２の各中心軸Ｃを上記所定距離から数ｍｍ程度の微小な距離だけ大きくするのに適している。
当該変形例のスクリーン装置は、第二のスライド部５ｂをｙ方向に移動させるという簡易な構成で、隣り合う線材２の間隔（目開き）の大きさを、線材２の「他端」から「一端」に向かって、長さ方向に次第に大きくなるよう制御可能である。従って、第一実施形態と同様、１つのスクリーン装置のみで、「他端」に供給した被処理物を「一端」に向かうまでに小径物から大径物へと多段階に分級したり、固液分離などの処理をすることができる。よって、当該変形例のスクリーン装置は、費用対効果の優れたスクリーン装置である。 <Modification of First Embodiment> (Plate-shaped screen device including second slide portion)
6 to 8 show modified examples of the first embodiment. The same parts or devices as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.
In the modification, as the slide portion, instead of the first slide portion 5a, a second slide in which a plurality of wedge portions 7 described later are arranged on the plate-shaped movement restricting portion 3 that abuts on the screen surface S in the z direction above. It differs from the first embodiment in that the portion 5b is used. The control device 6 also includes a moving mechanism (not shown) that moves the second slide portion 5b in the y direction, for example, a moving mechanism that uses a hydraulic cylinder, an electric cylinder, or the like. Can be moved along the screen surface S in a predetermined range in the + y direction (plus y direction, that is, positive direction on the y axis) and −y direction (minus y direction, that is, negative direction on the y axis). The point is also different from the first embodiment. The other points are the same as those of the screen device 1A of the first embodiment.
As shown in FIG. 8, the wedge portion 7 is formed in an isosceles triangular wedge shape when viewed in the xy plane. The length of the bottom side (short side in the x direction) of the wedge portion 7 is formed larger than the predetermined distance. An imaginary line connecting the midpoint of the bottom side and the apex angle is arranged in the y direction, and is also arranged at the midpoint of the interval between the first wire 2a and the second wire 2b. Here, as an example, the plurality of wedge portions 7 are arranged one in each of the gaps between the plurality of adjacent wire rods 2. When the first gap Ga is widened, each of the wedge portions 7 is independently and independently like a “curtain rail” on the movement restricting portion 3 along with the movement of each wire rod 2 in the x direction. It is desirable that the rod can be slid in the x direction and the axis of the rod can be displaced from the y direction.
Here, as shown in FIG. 6, the wedge portion 7 is an isosceles wedge-shaped wedge shape in the xz plane, and as shown in FIG. 7, a right-angled triangular wedge shape in the yz plane. And proceed with the discussion. The wedge portion 7 may be formed in a quadrangle shape when viewed in the xz plane and a quadrangle shape when viewed in the yz plane, depending on the cross-sectional shape of the wire 2.
The second slide portion 5b is arranged with the apex angle of the wedge portion 7 interposed between the one end of each of the first wire rod 2a and the second wire rod 2b and each of the first wire rod 2a and the second wire rod 2b as viewed in the xy plane and the z direction. Further, when viewed in the y direction, the bottom side of the wedge portion 7 is arranged outside the wire rod 2. Thereby, the distance in the x direction of each central axis C of the first wire rod 2a and the second wire rod 2b can be set to the predetermined distance.
When the first gap Ga is made larger than the second gap Gb from the state in which the first wire 2a and the second wire 2b are arranged at the above-mentioned predetermined distance, the control device 6 causes the second slide portion 5b to be screened. It moves in the + y direction (plus direction) along the surface S. Then, the bottom side gradually enters from the apex angle of the wedge portion 7 between the first wire rod 2a and the second wire rod 2b in the x direction and presses the first wire rod 2a and the second wire rod 2b in the x direction. , The first gap Ga can be made larger than the second gap Gb.
The screen device in which the second slide portion is used is suitable for increasing the central axes C of the adjacent wire rods 2 at the one end by a minute distance of about several mm from the predetermined distance.
The screen device of the modification has a simple configuration in which the second slide portion 5b is moved in the y direction, and the size of the interval (opening) between the adjacent wire rods 2 is set from the "other end" of the wire rods 2 to ". It can be controlled to gradually increase in the length direction toward “one end”. Therefore, similar to the first embodiment, with only one screen device, the object to be processed supplied to the "other end" can be classified in multiple stages from a small-diameter product to a large-diameter product by the time it goes to the "one end", Processing such as liquid separation can be performed. Therefore, the screen device of the modification is a cost effective screen device.

＜第二実施形態＞（第三のスライド部を備えた円筒状のスクリーン装置）
第二実施形態のスクリーン装置１Ｂについて、図９〜図１２を参照して説明する。
第二実施形態のスクリーン装置１Ｂは、第一実施形態にて互いに係止部４で接続された複数の線材２を、ｘｚ平面で見て円形且つスクリーン面Ｓが内面となるように丸めた円筒体を用いる点が、第一実施形態と大きく異なる。当該円筒体は、ｙ方向を各線材２の長さ方向とし、各線材２の中心軸Ｃがｘ方向で互いに平行、且つ、互いに上記所定距離の間隔を設けてｘｚ平面上で中心軸Ｏを中心とした同一円周上に規則的に並べた構成となる。
また、スライド部として、第一実施形態における第一のスライド部５ａに代わり、上底の外径が当該円筒体の内径より小さく、且つ、下底の外径が当該円筒体の内径より大きく、上底と下底の周囲を接続するテーパ面を備えた円錐台状の第三のスライド部５ｃを用いる点が異なる。第三のスライド部５ｃを、当該上底の中心から当該下底の中心に向かって大きな貫通孔が設けられた筒の形状（以下、「円錐台状の筒」という）とすれば、材料費を低減できるのみならず、後述の応用例３のように、第三のスライド部５ｃの当該貫通孔に被処理物Ｐを通過させる用途にも使用することができる。
さらに、第一実施形態における移動制限部３に代わり、当該円筒体が所定の外径より広がることのないよう、当該円筒体の外周を囲んで線材２の移動を制限する移動制限部８を用いる点が異なる。移動制限部８は、例えば、ｙ方向の長さが短く、ｘｚ平面で見て円形枠であり、その内径は、当該円筒体の外径よりやや大きく形成される。図示しないが、移動制限部８は、各線材２の両端付近にそれぞれ少なくとも１つづつ配置することが望ましい。
その上、制御装置６は、第三のスライド部５ｃをｙ方向に移動させる移動機構９、例えば、油圧シリンダや電動シリンダ等を用いた移動機構を備えており、第三のスライド部５ｃを、中心軸Ｏに沿って＋ｙ方向（プラスｙ方向、すなわちｙ軸上の正方向）及び-−ｙ方向（マイナスｙ方向、すなわちｙ軸上の負方向）に所定範囲内で移動させることができる点においても、第一実施形態と異なる。
また、図示しない電気モータ等を含む駆動装置で当該円筒体は中心軸Ｏの周りに所定速度で回転し、第三のスライド部５ｃが後述のように線材２に接触した場合、第三のスライド部５ｃも当該所定速度で当該円筒体と共に回転する点も、第一実施形態と異なる。その他の点は、第一実施形態のスクリーン装置１Ａと同様であるので、第一実施形態と同一の部品または装置等は、同一番号を付して、説明を省略する。 <Second embodiment> (Cylindrical screen device including third slide portion)
A screen device 1B of the second embodiment will be described with reference to FIGS. 9 to 12.
The screen device 1B of the second embodiment is a cylinder in which a plurality of wire rods 2 connected to each other by the locking portions 4 in the first embodiment are rounded so that the screen surface S is an inner surface when viewed in the xz plane. The point that a body is used is greatly different from the first embodiment. In the cylindrical body, the y direction is the length direction of each wire rod 2, the center axes C of the wire rods 2 are parallel to each other in the x direction, and the center axes O are arranged on the xz plane at intervals of the above predetermined distance. It will be arranged regularly on the same circumference as the center.
Further, as the slide portion, instead of the first slide portion 5a in the first embodiment, the outer diameter of the upper bottom is smaller than the inner diameter of the cylindrical body, and the outer diameter of the lower bottom is larger than the inner diameter of the cylindrical body, The difference is that a third truncated cone-shaped slide portion 5c having a tapered surface connecting the upper and lower bottoms is used. If the third slide portion 5c has a cylindrical shape having a large through hole from the center of the upper bottom toward the center of the lower bottom (hereinafter, referred to as “frustroconical cylinder”), the material cost is reduced. Can be reduced, and as in Application Example 3 described later, it can be used for the purpose of passing the object P through the through hole of the third slide portion 5c.
Further, instead of the movement restricting portion 3 in the first embodiment, a movement restricting portion 8 that surrounds the outer periphery of the cylindrical body and restricts the movement of the wire 2 is used so that the cylindrical body does not expand beyond a predetermined outer diameter. The points are different. The movement limiting portion 8 has, for example, a short length in the y direction, is a circular frame when viewed in the xz plane, and has an inner diameter slightly larger than the outer diameter of the cylindrical body. Although not shown, it is desirable that at least one movement limiting portion 8 is arranged near each end of each wire rod 2.
Moreover, the control device 6 includes a moving mechanism 9 that moves the third slide portion 5c in the y direction, for example, a moving mechanism that uses a hydraulic cylinder, an electric cylinder, or the like. A point that can be moved along the central axis O in the + y direction (plus y direction, that is, positive direction on the y axis) and −y direction (minus y direction, that is, negative direction on the y axis) within a predetermined range. Also, in this case, it is different from the first embodiment.
In addition, in a drive device including an electric motor (not shown), the cylindrical body rotates around the central axis O at a predetermined speed, and when the third slide portion 5c comes into contact with the wire rod 2 as described later, the third slide portion The point that the part 5c also rotates together with the cylindrical body at the predetermined speed is different from the first embodiment. Since the other points are the same as those of the screen device 1A of the first embodiment, the same parts or devices as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

第一の線材２ａと第二の線材２ｂの各中心軸Ｃが上記所定距離の間隔で配置された状態から第一の間隔Ｇａを第二の間隔Ｇｂより大きくする場合、制御装置６は、第三のスライド部５ｃを中心軸Ｏに沿って＋ｙ方向（プラス方向）へ移動する。すると、第一の線材２ａと第二の線材２ｂの各々の「一端」において、上記テーパ面が円筒体の内部に次第に入り込み、ｘｚ平面で見て中心軸Ｏから外方向に第一の線材２ａと第二の線材２ｂを押圧するので、第一の間隔Ｇａを第二の間隔Ｇｂより大きくすることができる。
なお、図１１に示すように、移動制限部８が存在するため、上記円筒体は、「一端」において、移動制限部８の内径より大きく押し広げることはできない。また、上述のとおり、当該円筒体は所定速度で回転しているが、第三のスライド部５ｃも当該所定速度で回転するため、第三のスライド部５ｃのテーパ面と線材２との間で摩擦が生じる等の不具合の発生を防止できる。 When making the first gap Ga larger than the second gap Gb from the state where the central axes C of the first wire rod 2a and the second wire rod 2b are arranged at the gaps of the above-mentioned predetermined distance, the control device 6 The third slide portion 5c is moved along the central axis O in the + y direction (plus direction). Then, at each "one end" of the first wire rod 2a and the second wire rod 2b, the tapered surface gradually enters the inside of the cylindrical body, and the first wire rod 2a extends outward from the central axis O when viewed in the xz plane. Since the second wire rod 2b is pressed, the first gap Ga can be made larger than the second gap Gb.
Note that, as shown in FIG. 11, since the movement restricting portion 8 exists, the cylindrical body cannot be wider than the inner diameter of the movement restricting portion 8 at one end. Further, as described above, the cylindrical body rotates at a predetermined speed, but the third slide portion 5c also rotates at the predetermined speed, so that between the tapered surface of the third slide portion 5c and the wire 2. It is possible to prevent the occurrence of problems such as friction.

なお、スクリーン装置１Ｂを用いて汚泥等の固液分離の処理を行う場合、「一端」が「他端」よりｚ方向の下方となるよう、ｙ方向を水平線より傾けて使用するのが望ましい。この場合、スクリーン面Ｓのｚ方向上方から上記他端付近のスクリーン面Ｓに被処理物Ｐである汚泥等が供給される。   When performing the solid-liquid separation process of sludge or the like using the screen device 1B, it is desirable to use the y direction inclined with respect to the horizontal line so that the “one end” is below the “other end” in the z direction. In this case, sludge or the like as the object to be treated P is supplied to the screen surface S near the other end from above the screen surface S in the z direction.

以上の説明においては、スクリーン装置１Ｂは、係止部４で接続された複数の線材２を、ｘｚ平面で見て円形且つスクリーン面Ｓが内面となるように丸めた円筒体を用いた。しかし、用途によっては、図１３に示すように、係止部４で接続された複数の線材２を、ｘｚ平面で見て円形且つスクリーン面Ｓが外面となるように丸めた円筒体としてもよい。   In the above description, the screen device 1B uses a cylindrical body in which the plurality of wire rods 2 connected by the locking portions 4 are rounded when viewed in the xz plane and the screen surface S is an inner surface. However, depending on the application, as shown in FIG. 13, a plurality of wire rods 2 connected by the locking portions 4 may be a cylindrical body that is circular when viewed in the xz plane and is rounded so that the screen surface S is the outer surface. .

以上のように、第二実施形態のスクリーン装置１Ｂは、第三のスライド部５ｃをｙ方向に移動させるという簡易な構成で、図１２に示すように円筒体の内径を押し広げ、隣り合う線材２の間隔（目開き）の大きさを、線材２の「他端」から「一端」に向かって、長さ方向に次第に大きくなるよう制御可能である。従って、第一実施形態やその変形例と同様、１つのスクリーン装置のみで、「他端」に供給した被処理物を「一端」に向かうまでに小径物から大径物へと多段階に分級したり、固液分離などの処理をすることができる。よって、第二実施形態のスクリーン装置１Ｂは、費用対効果の優れたスクリーン装置である。   As described above, the screen device 1B according to the second embodiment has a simple configuration in which the third slide portion 5c is moved in the y direction, and as shown in FIG. The size of the interval (opening) of 2 can be controlled so as to gradually increase in the length direction from the “other end” to the “one end” of the wire rod 2. Therefore, similar to the first embodiment and its modified example, only one screen device classifies the object to be processed supplied to the "other end" in multiple stages from the small diameter product to the large diameter product by the time it goes to the "one end". Or solid-liquid separation can be performed. Therefore, the screen device 1B of the second embodiment is a cost-effective screen device.

（第二実施形態の変形例）（第四のスライド部を備えた円筒状のスクリーン装置）
図示しないが、第一実施形態の変形例で示した第二のスライド部５ｂに類似の構成を、第二実施形態のスクリーン装置１Ｂに適用してもよい。
すなわち、スライド部として、第三のスライド部５ｃに代わり、移動制限部８に第二のスライド部５ｂの楔部７を複数配置した第四のスライド部を用いる点で、第二実施形態と異なる。
また、制御装置６は、第三のスライド部５ｃを移動する移動機構９に代わり、第四のスライド部をｙ方向（円筒体の中心軸Ｏの延びる軸線方向）に移動させる移動機構、例えば、油圧シリンダや電動シリンダ等を用いた移動機構（図示無し）を備えており、第四のスライド部を、＋ｙ方向（プラスｙ方向、すなわちｙ軸上の正方向）及び−ｙ方向（マイナスｙ方向、すなわちｙ軸上の負方向）に所定範囲内で移動させることができる点においても、第二実施形態と異なる。その他の点は、第二実施形態のスクリーン装置１Ｂと同様である。
第一の線材２ａと第二の線材２ｂの中心軸Ｃが上記所定距離に配置された状態から第一の間隔Ｇａを第二の間隔Ｇｂより大きくする場合、制御装置６は、第四のスライド部を中心軸Ｏに沿って＋ｙ方向（プラス方向）へ移動する。すると、第一の線材２ａと第二の線材２ｂの各々の「一端」において、第一の線材２ａと第二の線材２ｂの間に、楔部７の頂角から底辺が次第に入り込んで第一の線材２ａと第二の線材２ｂを押圧するので、第一の間隔Ｇａを第二の間隔Ｇｂより大きくすることができる。この場合、「一端」において、上記所定距離に配置された状態に比べ、上記円筒体の直径が大きくなる。このため、各々の楔部７は、第一の間隔Ｇａが広げられる際、各線材２が移動制限部８に向かって当該直径方向に広がることが可能な形状、例えば、ｘｚ平面で見て底辺が移動制限部８に接続する二等辺三角形の形状の楔型となるよう構成される。
当該変形例のスクリーン装置は、第四のスライド部をｙ方向に移動させるという簡易な構成で、隣り合う線材２の間隔（目開き）の大きさを、線材２の「他端」から「一端」に向かって、長さ方向に次第に大きくなるよう制御可能である。従って、第一実施形態やその変形例並びに第二実施形態と同様、１つのスクリーン装置のみで、「他端」に供給した被処理物を「一端」に向かうまでに小径物から大径物へと多段階に分級したり、固液分離などの処理をすることができる。よって、当該変形例のスクリーン装置は、費用対効果の優れたスクリーン装置である。 (Modification of Second Embodiment) (Cylindrical Screen Device Having Fourth Slide Part)
Although not shown, a configuration similar to the second slide portion 5b shown in the modification of the first embodiment may be applied to the screen device 1B of the second embodiment.
That is, the third embodiment is different from the second embodiment in that, instead of the third slide part 5c, a fourth slide part having a plurality of wedge parts 7 of the second slide part 5b arranged in the movement restricting part 8 is used as the slide part. .
Further, the control device 6 moves the fourth slide part in the y direction (the axial direction in which the central axis O of the cylindrical body extends) instead of the moving mechanism 9 that moves the third slide part 5c, for example, A moving mechanism (not shown) using a hydraulic cylinder, an electric cylinder, or the like is provided, and the fourth slide portion is moved in the + y direction (plus y direction, that is, the positive direction on the y axis) and the −y direction (minus y direction). That is, it is also different from the second embodiment in that it can be moved within a predetermined range in the negative direction on the y-axis). The other points are the same as those of the screen device 1B of the second embodiment.
When the first gap Ga is made larger than the second gap Gb from the state where the central axes C of the first wire rod 2a and the second wire rod 2b are arranged at the predetermined distance, the control device 6 causes the fourth slide to move. The part is moved along the central axis O in the + y direction (plus direction). Then, at the "one end" of each of the first wire 2a and the second wire 2b, the bottom gradually enters from the apex angle of the wedge portion 7 between the first wire 2a and the second wire 2b. Since the second wire 2a and the second wire 2b are pressed, the first gap Ga can be made larger than the second gap Gb. In this case, the diameter of the cylindrical body at the "one end" is larger than that in the state of being arranged at the predetermined distance. Therefore, each wedge portion 7 has a shape such that each wire rod 2 can spread in the diametrical direction toward the movement restricting portion 8 when the first gap Ga is widened, for example, the bottom side when viewed in the xz plane. Is formed into a wedge shape connected to the movement restricting portion 8 in the shape of an isosceles triangle.
The screen device of the modified example has a simple configuration in which the fourth slide portion is moved in the y direction, and the size of the interval (opening) between the adjacent wire rods 2 is changed from the “other end” to the “one end” of the wire rods 2. It is possible to control so as to gradually increase in the length direction. Therefore, similar to the first embodiment and its modified example and the second embodiment, only one screen device changes the object to be processed supplied to the "other end" from the small diameter object to the large diameter object by the time it goes to the "one end". Thus, it is possible to perform classification such as multi-stage classification and solid-liquid separation. Therefore, the screen device of the modification is a cost effective screen device.

次に、第一実施形態の平板状のスクリーン装置１Ａ及びその変形例、並びに、第二実施形態の円筒状のスクリーン装置１Ｂ及びその変形例を適用した処理システムを、応用例として説明する。   Next, a flat screen device 1A according to the first embodiment and a modification thereof, and a cylindrical screen device 1B according to the second embodiment and a processing system to which the modification is applied will be described as application examples.

＜応用例１＞（夾雑物除去システム）
図１４の処理システムは、第二実施形態のスクリーン装置１Ｂを用いた夾雑物除去システム１０である。夾雑物除去システム１０では、被処理物Ｐとして、例えば、し尿、浄化槽汚泥等の汚泥を使用し、当該汚泥の中から繊維質（トイレットペーパーや髪の毛等）を分離する。
夾雑物除去システム１０は、スクリーン装置１Ｂと、スクリーン装置１Ｂの円筒体を中心軸Ｏの周りに回転する電気モータ等の駆動装置１１と、スクリーン装置１Ｂの円筒体の内部へ被処理物Ｐを供給する被処理物導入管１２と、当該供給される被処理物Ｐの含水率を測定する水分測定装置１３を少なくとも備えている。スクリーン装置１Ｂの制御装置６は、水分測定装置１３による当該含水率に対応する測定結果を受け、当該含水率に応じて、第三のスライド部５ｃをｙ方向に移動させる。
具体的には、制御装置６は、当該含水率が所定値より低い場合、第一の間隔Ｇａを第二の間隔Ｇｂより大きくするよう、第三のスライド部５ｃを＋ｙ方向（プラスｙ方向）に移動する。一方、制御装置６は、当該含水率が当該所定値より高い場合、第一の間隔Ｇａを上記所定距離まで狭めるよう、第三のスライド部５ｃを−ｙ方向（マイナスｙ方向）に移動する。なお、制御装置６は、例えば、第一の間隔Ｇａを第二の間隔Ｇｂより大きくした場合の互いの差が例えば最大約３ｍｍとなるよう、第三のスライド部５ｃを＋ｙ方向（プラスｙ方向）に移動する。
すなわち、夾雑物除去システム１０は、被処理物Ｐの含水率に応じて、隣り合う線材２の間隔（目開き）の大きさを、線材２の「他端」から「一端」に向かって、長さ方向に次第に大きくなるよう制御可能である。従って、１つのスクリーン装置のみで、「他端」に供給した被処理物から高速に水分を取り除き、且つ、繊維質を分離することができる。よって、夾雑物除去システム１０は、費用対効果に優れるのみならず、固液分離の処理に優れた性能を発揮することができる処理システムである。
なお、制御装置６は、駆動装置１１の駆動も制御しており、当該含水率が当該所定値より高い場合、当該円筒体の回転速度を所定速度より遅くし、当該含水率が当該所定値より低い場合、当該円筒体の回転速度を所定速度より早くする。このため、上記円筒体内で繊維質を回転させながらロール状に成形することが容易となり、ロール状となった繊維質で目詰まりする恐れのある繊維質を取り込むので、当該円筒体のセルフクリーニングが可能となる。
また、当該円筒体は、「他端」において、一部の線材２と固定され、直接的または間接的に駆動装置１１の駆動力を伝達して当該円筒体を回転させるための支柱または壁板１４に接続される。後述するように、「他端」に第三または第四のスライド部を配置して、第二の間隔Ｇｂも変更可能とする場合には、ｘｚ平面において、支柱または壁板１４が中心軸Ｏから外側に向かって延伸可能な構成とすればよい。 <Application example 1> (Contaminant removal system)
The processing system of FIG. 14 is a contaminant removal system 10 using the screen device 1B of the second embodiment. In the contaminant removal system 10, sludge such as human waste and septic tank sludge is used as the object P to be treated, and fibers (toilet paper, hair, etc.) are separated from the sludge.
The contaminant removal system 10 includes a screen device 1B, a drive device 11 such as an electric motor that rotates a cylindrical body of the screen device 1B around a central axis O, and an object P to be processed inside the cylindrical body of the screen device 1B. It is provided with at least a workpiece introduction pipe 12 to be supplied, and a moisture measuring device 13 for measuring the water content of the workpiece P to be supplied. The control device 6 of the screen device 1B receives the measurement result corresponding to the moisture content by the moisture measuring device 13, and moves the third slide portion 5c in the y direction according to the moisture content.
Specifically, when the water content is lower than a predetermined value, the control device 6 sets the third slide portion 5c in the + y direction (plus y direction) so that the first space Ga is larger than the second space Gb. Move to. On the other hand, when the water content is higher than the predetermined value, the control device 6 moves the third slide portion 5c in the −y direction (minus y direction) so as to reduce the first distance Ga to the predetermined distance. Note that the control device 6 sets the third slide portion 5c in the + y direction (plus y direction) so that the difference between the first gap Ga and the second gap Gb becomes, for example, about 3 mm at maximum when the first gap Ga is larger than the second gap Gb. ) Move to.
That is, the contaminant removal system 10 changes the size of the interval (opening) between the adjacent wire rods 2 from “the other end” to “one end” of the wire rods 2 according to the water content of the object P to be treated. It can be controlled to gradually increase in the length direction. Therefore, with only one screen device, it is possible to remove moisture from the object to be processed supplied to the "other end" at high speed and separate the fibrous material. Therefore, the contaminant removal system 10 is a processing system that is not only cost-effective, but can also exhibit excellent performance in solid-liquid separation processing.
Note that the control device 6 also controls the drive of the drive device 11, and when the water content is higher than the predetermined value, the rotation speed of the cylindrical body is made slower than the predetermined speed, and the water content is lower than the predetermined value. If it is low, the rotation speed of the cylindrical body is made higher than a predetermined speed. Therefore, it becomes easy to form a roll while rotating the fiber in the cylindrical body, and since the fiber that may be clogged with the rolled fiber is taken in, self-cleaning of the cylindrical body is possible. It will be possible.
Further, the cylindrical body is fixed to a part of the wire rod 2 at the "other end", and a pillar or a wall plate for directly or indirectly transmitting the driving force of the driving device 11 to rotate the cylindrical body. 14 is connected. As will be described later, when the third or fourth slide portion is arranged at the “other end” so that the second gap Gb can also be changed, in the xz plane, the pillar or the wall plate 14 has the central axis O. It may be configured so that it can be stretched from the outside to the outside.

なお、本応用例では、第三のスライド部５ｃを備えたスクリーン装置１Ｂ（第二実施形態）を用いて説明したが、第四のスライド部を備えたスクリーン装置（第二実施形態の変形例）を用いても、上述の優れた性能を備えた処理システムとなる。   In addition, although this application example demonstrated using the screen apparatus 1B (2nd embodiment) provided with the 3rd slide part 5c, the screen apparatus provided with the 4th slide part (Modification of 2nd embodiment). ) Is used, the processing system has the above-mentioned excellent performance.

＜応用例２＞（汚泥脱水システム）
図１５の処理システムは、第二実施形態のスクリーン装置１Ｂを用いた汚泥脱水システム１５である。ここでは、被処理物Ｐは汚泥である。汚泥脱水システム１５は、スクリーン装置１０Ｂと、当該円筒体の内周近傍まで長さのあるスクリュー羽根１７を備え、中心軸Ｏに配置されたスクリュー軸１８と、中心軸Ｏに配置され、スクリュー軸１８と同軸且つスクリュー軸１８の内側に二重管構造で配置された被処理物導入管１２ａと、被処理物導入管１２ａで搬送される被処理物Ｐ（汚泥）の含水率を測定する水分測定装置１３ａとを少なくとも備えている。
汚泥脱水システム１５は、図示しない駆動装置により、当該スクリュー軸１８と当該円筒体をそれぞれ別々の回転速度で高速回転させ、被処理物導入管１２ａの先端に形成された被処理物供給孔１９から当該円筒体の「一端」のスクリーン面Ｓに供給された被処理物Ｐを「他端」まで圧搾しつつ搬送し、「他端」の近傍に配置された脱水ケーキ排出孔２０から脱水ケーキを排出する。スクリュー軸１８は、上記円筒体内で、「一端」から「他端」に向かうにつれて拡径しているため、当該圧搾が可能となる。
当該高速回転により遠心力で汚泥の水分を脱水するので、周囲に汚水等が飛び散らないよう、汚泥脱水システム１５は、当該円筒体の周囲を取り囲むケーシング１６を備えている。また、ケーシング１６は、脱水された水分（分離液）を排出する分離液排出管２１と、脱水ケーキ排出孔２０から排出される脱水ケーキを排出する脱水ケーキ排出管２２を備えている。 <Application example 2> (sludge dewatering system)
The treatment system of FIG. 15 is a sludge dewatering system 15 using the screen device 1B of the second embodiment. Here, the processing object P is sludge. The sludge dewatering system 15 includes a screen device 10B and a screw blade 17 having a length up to the vicinity of the inner circumference of the cylindrical body. The sludge dewatering system 15 includes a screw shaft 18 arranged on the central axis O and a screw shaft 18 arranged on the central axis O. Moisture for measuring the water content of the object-to-be-processed introduction pipe 12a arranged coaxially with 18 and having a double tube structure inside the screw shaft 18 and the object-to-be-processed P (sludge) conveyed by the object-to-be-processed introduction pipe 12a. At least the measuring device 13a is provided.
The sludge dewatering system 15 rotates the screw shaft 18 and the cylindrical body at different rotational speeds at high speeds by a driving device (not shown), and from the workpiece supply hole 19 formed at the tip of the workpiece introducing pipe 12a. The object to be treated P supplied to the screen surface S at "one end" of the cylindrical body is conveyed while being squeezed to the "other end", and the dehydrated cake is discharged from the dehydrated cake discharge hole 20 arranged near the "other end". Discharge. Since the screw shaft 18 is expanded in diameter from the “one end” to the “other end” in the cylindrical body, the compression can be performed.
Since the water content of the sludge is dehydrated by centrifugal force due to the high-speed rotation, the sludge dewatering system 15 includes a casing 16 that surrounds the circumference of the cylindrical body so that the wastewater and the like do not scatter around. Further, the casing 16 includes a separated liquid discharge pipe 21 for discharging dehydrated water (separated liquid) and a dehydrated cake discharge pipe 22 for discharging the dehydrated cake discharged from the dehydrated cake discharge hole 20.

スクリーン装置１Ｂの制御装置６は、水分測定装置１３ａによる当該含水率に対応する測定結果を受け、当該含水率に応じて、第三のスライド部５ｃをｙ方向に移動させる。
具体的には、制御装置６は、当該含水率が所定値より低い場合、第一の間隔Ｇａを第二の間隔Ｇｂより大きくするよう、第三のスライド部５ｃを＋ｙ方向（プラスｙ方向）に移動する。一方、制御装置６は、当該含水率が当該所定値より高い場合、第一の間隔Ｇａを上記所定距離まで狭めるよう、第三のスライド部５ｃを−ｙ方向（マイナスｙ方向）に移動する。
なお、上述のように上記円筒体は高速回転し、且つ、上記一端から上記他端に向かって汚泥は圧搾されながら搬送されるため、「他端」側では汚泥に加えられる圧力が「一端」側に比べて高くなる。よって、「他端」側では、隣り合う線材２の間隔（目開き）から汚泥が抜け出る恐れがある。そこで、被処理物Ｐである汚泥の脱水も適切に行いつつ、当該汚泥が脱水ケーキ排出孔２０に搬送される前に当該円筒体の外部へ排出されるのを防止するため、制御装置６は、例えば、第一の間隔Ｇａを第二の間隔Ｇｂより大きくした場合の互いの差が例えば最大約０.１〜２ｍｍとなるよう、第三のスライド部５ｃを＋ｙ方向（プラスｙ方向）に移動する。
すなわち、汚泥脱水システム１５は、被処理物Ｐである汚泥の含水率に応じて、隣り合う線材２の間隔（目開き）の大きさを、線材２の「他端」から「一端」に向かって、長さ方向に次第に大きくなるよう制御可能である。言い換えれば、汚泥脱水システム１５は、被処理物Ｐである汚泥の含水率に応じて、隣り合う線材２の間隔（目開き）の大きさを、線材２の「一端」から「他端」に向かって、長さ方向に次第に小さくなるよう制御可能である。
従って、１つのスクリーン装置のみで、「一端」に供給した汚泥から適切且つ高速に水分を取り除き、且つ、脱水ケーキを得ることができる。よって、汚泥脱水システム１５は、費用対効果に優れるのみならず、汚泥脱水の処理に優れた性能を発揮することができる処理システムである。 The control device 6 of the screen device 1B receives the measurement result corresponding to the water content by the moisture measuring device 13a, and moves the third slide portion 5c in the y direction according to the water content.
Specifically, when the water content is lower than a predetermined value, the control device 6 sets the third slide portion 5c in the + y direction (plus y direction) so that the first space Ga is larger than the second space Gb. Move to. On the other hand, when the water content is higher than the predetermined value, the control device 6 moves the third slide portion 5c in the -y direction (minus y direction) so as to narrow the first gap Ga to the predetermined distance.
As described above, since the cylindrical body rotates at high speed and the sludge is conveyed while being squeezed from the one end to the other end, the pressure applied to the sludge on the “other end” side is “one end”. High compared to the side. Therefore, on the "other end" side, there is a risk that sludge may come out from the space (opening) between the adjacent wire rods 2. Therefore, in order to prevent the sludge, which is the material to be treated P, from being drained to the outside of the cylindrical body before being conveyed to the dehydration cake discharge hole 20, the control device 6 controls the sludge appropriately. , The third slide portion 5c is moved in the + y direction (plus y direction) so that the difference between the first distance Ga and the second distance Gb is about 0.1 to 2 mm at maximum. Moving.
That is, the sludge dewatering system 15 changes the size of the interval (opening) between the adjacent wire rods 2 from “the other end” to “one end” of the wire rods 2 according to the water content of the sludge that is the object to be treated P. Therefore, it can be controlled so as to gradually increase in the length direction. In other words, the sludge dewatering system 15 changes the size of the interval (opening) between the adjacent wire rods 2 from “one end” to “the other end” of the wire rods 2 according to the water content of the sludge that is the object to be treated P. It is possible to control so as to gradually decrease in the longitudinal direction.
Therefore, with only one screen device, it is possible to remove water from the sludge supplied to "one end" appropriately and at high speed, and obtain a dehydrated cake. Therefore, the sludge dewatering system 15 is a treatment system that is not only cost-effective, but can also exhibit excellent performance in sludge dewatering.

なお、本応用例では、第三のスライド部５ｃを備えたスクリーン装置１Ｂ（第二実施形態）を用いて説明したが、第四のスライド部を備えたスクリーン装置（第二実施形態の変形例）を用いても、上述の優れた性能を備えた処理システムとなる。   In addition, although this application example demonstrated using the screen apparatus 1B (2nd embodiment) provided with the 3rd slide part 5c, the screen apparatus provided with the 4th slide part (Modification of 2nd embodiment). ) Is used, the processing system has the above-mentioned excellent performance.

＜応用例３＞（滑剤供給システム）
図１６の処理システムは、第二実施形態のスクリーン装置１Ｂを用いた滑剤供給システム２３である。ここでは、被処理物Ｐは汚泥である。当該汚泥は、例えば、応用例２の汚泥脱水システム１５によって脱水処理がなされた汚泥、すなわち含水量が少なく粘度が高い脱水ケーキである。
滑剤供給システム２３は、スクリーン装置１０Ｂと、当該円筒体の周囲を覆い且つ滑剤Ｌを貯留した貯留タンク２４と、当該円筒体の外部に配置され、当該汚泥を「他端」から「一端」に向かって当該円筒体内のスクリーン面Ｓ上へ圧送する汚泥圧送装置２５と、当該円筒体へ供給される汚泥の含水率を測定する水分測定装置１３ｂとを少なくとも備えている。
スクリーン装置１Ｂの第三のスライド部５ｃは、ここでは、上述した「円錐台状の筒」の形状である。
汚泥圧送装置２５から当該円筒体へ汚泥を供給する被処理物供給管１２ｂは、当該円筒体の「他端」に向かって縮径した形状であり、当該円筒体の内部へ「他端」から挿入される。被処理物供給管１２ｂは、「他端」において当該円筒体の内径と実質的に同一寸法の外径である。
当該円筒体の「一端」から滑剤Ｌが付着した汚泥が排出され、且つ、パイプラインを形成して所定のプラント等まで当該汚泥を搬送する搬送管２６は、当該円筒体の「一端」から拡径した形状であり、当該円筒体の外面を覆うように「一端」側から挿入される。搬送管２６は、「一端」において当該円筒体の外径と実質的に同一寸法の内径である。当該内径は、移動制限部８の内径と実質的に同じ寸法にしてもよい。
滑剤Ｌは、滑剤充填装置２７によって、貯留タンク２４へ導入される。滑剤充填装置２７を貯留タンク２４のｚ方向上方へ配置すれば、搬送や加圧のためのポンプ等の動力を要せず、重力落下により滑剤Ｌを充填することができるので、運転コストを低減可能である。
貯留タンク２４に一杯に貯留された滑剤Ｌは、上記円筒体の隣り合う線材２の間隔（目開き）から、当該円筒体の内部に入り込み、当該円筒体内を圧送される汚泥の周囲に塗布される。
なお、滑剤となる材料は、粉末状または顆粒状であり、通常、液体に溶かした滑剤溶液の状態で汚泥に塗布される。しかし、滑剤供給システム２３においては、滑剤Ｌが粉末状または顆粒状であっても、当該円筒体の全周囲の線材２の間から、直線的且つ連続的に汚泥に滑剤Ｌを均等かつ適切に塗布させることができ、汚泥に接触した滑剤Ｌは汚泥の水分を吸収して汚泥を取り巻く滑剤溶液の液膜となるので、当初から滑剤溶液の状態で滑剤Ｌを準備する必要がない。すなわち、滑剤供給システム２３では、滑剤Ｌは、当該滑剤溶液であってもよいし、粉体状または顆粒状の当該材料そのものであってもよい。滑剤Ｌとして当該材料そのものを使用する場合は、滑剤溶液を生成するための装置が不要となるため、製造コストや運転コストを低減可能である。 <Application example 3> (lubricant supply system)
The processing system of FIG. 16 is a lubricant supply system 23 using the screen device 1B of the second embodiment. Here, the processing object P is sludge. The sludge is, for example, a sludge dehydrated by the sludge dewatering system 15 of Application Example 2, that is, a dehydrated cake having a low water content and a high viscosity.
The lubricant supply system 23 is disposed outside the screen device 10B, a storage tank 24 that covers the periphery of the cylinder and stores the lubricant L, and the sludge from the "other end" to the "one end". At least a sludge pumping device 25 for pumping to the screen surface S in the cylinder body and a moisture measuring device 13b for measuring the water content of the sludge supplied to the cylinder body are provided.
Here, the third slide portion 5c of the screen device 1B is in the shape of the above-mentioned "frustroconical cylinder".
The object supply pipe 12b for supplying sludge from the sludge pumping device 25 to the cylindrical body has a shape in which the diameter is reduced toward the "other end" of the cylindrical body, and the inside of the cylindrical body is supplied from the "other end". Is inserted. The workpiece supply pipe 12b has an outer diameter that is substantially the same as the inner diameter of the cylindrical body at the "other end".
The sludge to which the lubricant L adheres is discharged from "one end" of the cylindrical body, and the conveying pipe 26 that forms the pipeline and conveys the sludge to a predetermined plant or the like is expanded from "one end" of the cylindrical body. It has a diameter and is inserted from the "one end" side so as to cover the outer surface of the cylindrical body. The carrier pipe 26 has an inner diameter that is substantially the same as the outer diameter of the cylindrical body at one end. The inner diameter may be substantially the same as the inner diameter of the movement restricting portion 8.
The lubricant L is introduced into the storage tank 24 by the lubricant filling device 27. By disposing the lubricant filling device 27 above the storage tank 24 in the z direction, it is possible to fill the lubricant L by gravity fall without the need of power such as a pump for transportation or pressurization, and thus the operating cost is reduced. It is possible.
The lubricant L fully stored in the storage tank 24 enters the inside of the cylindrical body from the space (opening) between the adjacent wire rods 2 of the cylindrical body, and is applied around the sludge pumped in the cylindrical body. It
The material to be the lubricant is in the form of powder or granules and is usually applied to the sludge in the form of a lubricant solution dissolved in a liquid. However, in the lubricant supply system 23, even if the lubricant L is in the form of powder or granules, the lubricant L is evenly and appropriately applied to the sludge linearly and continuously from between the wire rods 2 around the entire circumference of the cylindrical body. Since the lubricant L that can be applied and has come into contact with the sludge absorbs the water content of the sludge and becomes a liquid film of the lubricant solution surrounding the sludge, it is not necessary to prepare the lubricant L in the state of the lubricant solution from the beginning. That is, in the lubricant supply system 23, the lubricant L may be the lubricant solution or the material itself in the form of powder or granules. When the material itself is used as the lubricant L, a device for generating the lubricant solution is not required, and thus manufacturing cost and operation cost can be reduced.

スクリーン装置１Ｂの制御装置６は、水分測定装置１３ｂによる当該含水率に対応する測定結果を受け、当該含水率に応じて、第三のスライド部５ｃをｙ方向に移動させる。
具体的には、制御装置６は、当該含水率が所定値より低い場合、第一の間隔Ｇａを第二の間隔Ｇｂより大きくして滑剤Ｌが塗布される汚泥の面積を増加するよう、第三のスライド部５ｃを＋ｙ方向（プラスｙ方向）に移動する。一方、制御装置６は、当該含水率が当該所定値より高い場合、第一の間隔Ｇａを上記所定距離まで狭めるよう、第三のスライド部５ｃを−ｙ方向（マイナスｙ方向）に移動する。
上述のように、被処理物供給管１２ｂは、当該円筒体の「他端」に向かって縮径した形状であるため、「他端」側では汚泥に加えられる圧力が高く、隣り合う線材２の間隔（目開き）から貯留タンク２４へ汚泥が抜け出る恐れがある。一方、汚泥の周囲に滑剤Ｌが塗布されれば、汚泥と線材２との摩擦抵抗が大幅に低減されるので、汚泥は当該円筒内を「一端」側へ円滑に搬送される。従って、「一端」側では、隣り合う線材２の間隔（目開き）を「他端」側より大きくして、さらに滑剤Ｌを多量に汚泥に塗布し、搬送管２６で汚泥を搬送する際の搬送管２６内壁との摩擦抵抗をさらに低減することが可能となる。
そこで、低い摩擦抵抗で搬送管２６による汚泥の搬送を可能にしつつ、被処理物Ｐである汚泥が「一端」に圧送される前に当該円筒体の外部へ排出されるのを防止するため、制御装置６は、例えば、第一の間隔Ｇａを第二の間隔Ｇｂより大きくした場合の互いの差が例えば最大約０.１〜１ｍｍとなるよう、第三のスライド部５ｃを＋ｙ方向（プラスｙ方向）に移動する。
すなわち、滑剤供給システム２３は、被処理物Ｐの含水率に応じて、隣り合う線材２の間隔（目開き）の大きさを、線材２の「他端」から「一端」に向かって、長さ方向に次第に大きくなるよう制御可能である。
従って、滑剤供給システム２３は、１つのスクリーン装置のみで、「他端」に供給した被処理物に滑剤を適切に塗布することができる。すなわち、滑剤供給システム２３は、費用対効果に優れるのみならず、滑剤塗布の処理に優れ、且つ、圧送動力を低減してパイプラインによる被処理物の搬送性能を向上した処理システムである。 The control device 6 of the screen device 1B receives the measurement result corresponding to the water content by the moisture measuring device 13b, and moves the third slide portion 5c in the y direction according to the water content.
Specifically, when the water content is lower than a predetermined value, the control device 6 makes the first gap Ga larger than the second gap Gb to increase the area of the sludge to which the lubricant L is applied. The third slide portion 5c is moved in the + y direction (plus y direction). On the other hand, when the water content is higher than the predetermined value, the control device 6 moves the third slide portion 5c in the -y direction (minus y direction) so as to narrow the first gap Ga to the predetermined distance.
As described above, since the workpiece supply pipe 12b has a shape in which the diameter is reduced toward the “other end” of the cylindrical body, the pressure applied to the sludge on the “other end” side is high and the adjacent wire rods 2 There is a risk that sludge will escape to the storage tank 24 from the interval (opening). On the other hand, if the lubricant L is applied around the sludge, the frictional resistance between the sludge and the wire 2 is significantly reduced, so that the sludge is smoothly transported to the "one end" side in the cylinder. Therefore, at the "one end" side, the interval (opening) between the adjacent wire rods 2 is made larger than that at the "other end" side, and a large amount of the lubricant L is applied to the sludge, and when the sludge is transported by the transport pipe 26. It is possible to further reduce the frictional resistance with the inner wall of the transport pipe 26.
Therefore, in order to enable the sludge to be transported by the transport pipe 26 with low friction resistance, and to prevent the sludge, which is the object to be treated P, from being discharged to the outside of the cylindrical body before being pumped to one end, The control device 6 sets the third slide portion 5c in the + y direction (plus) so that the difference between the first gap Ga and the second gap Gb is set to be, for example, about 0.1 to 1 mm at maximum. move in the y direction).
That is, the lubricant supply system 23 changes the size of the interval (opening) between the adjacent wire rods 2 from “the other end” to “one end” of the wire rods 2 according to the water content of the object P to be treated. It can be controlled so as to gradually increase in the vertical direction.
Therefore, the lubricant supply system 23 can appropriately apply the lubricant to the object to be processed supplied to the "other end" with only one screen device. That is, the lubricant supply system 23 is not only cost-effective, but also excellent in lubricant application processing, and is a processing system in which the pressure-feeding power is reduced to improve the performance of conveying the object to be processed by the pipeline.

なお、本応用例では、第三のスライド部５ｃを備えたスクリーン装置１Ｂ（第二実施形態）を用いて説明したが、第四のスライド部を備えたスクリーン装置（第二実施形態の変形例）を用いても、上述の優れた性能を備えた処理システムとなる。   In addition, although this application example demonstrated using the screen apparatus 1B (2nd embodiment) provided with the 3rd slide part 5c, the screen apparatus provided with the 4th slide part (Modification of 2nd embodiment). ) Is used, the processing system has the above-mentioned excellent performance.

＜応用例４＞（焼却残渣分級システム）
図１７の処理システムは、第一実施形態のスクリーン装置１Ａを用いた焼却残渣分級システム２８である。ここでは、被処理物Ｐは、ストーカ炉等のごみ焼却炉２９で焼却された焼却残渣である。
焼却残渣分級システム２８は、ごみ焼却炉２９と、ごみ焼却炉２９で廃棄物が焼却され且つ排出された焼却残渣を受けて水中等で冷却し、搬送装置（例えば、ベルトコンベヤ、スクリューコンベヤ、スクレーパコンベヤ、フライトコンベヤ、等）で排出する灰出装置３０と、灰出装置３０が排出する焼却残渣を受けて分級するスクリーン装置１０Ａとを少なくとも備えている。スクリーン装置１０Ａの下方にさらにスクリーン装置１０Ａを配置し、さらに分級してもよい。
スクリーン装置１０Ａは、スクリーン面Ｓを上方に向け、且つ、「他端」から「一端」に向かって下り傾斜となるよう配置される。そして、灰出装置３０が排出した焼却残渣を「他端」に受ける。「他端」に受けた被処理物Ｐである焼却残渣は、自重でスクリーン面Ｓを滑り落ちながら分級される。
スクリーン装置１０Ａの下方には、少なくとも液体、小径物、大径物の３つの分級物に分離して収納することができる分級容器３２が配置される。当該大径物は金属等の不燃物である可能性が高いが、小径物は焼却可能な未燃物である場合が多いため、随時、制御装置６がベルトコンベヤ等の搬送装置３３を制御して、当該小径物をごみホッパ３１へ投入し、ごみ焼却炉２９で再び燃焼する。また、分級された当該液体は、廃液であるが、例えば、ごみ焼却炉２９で発生する排ガスを冷却するために当該排ガスに向かって噴霧されるなど、再利用される。 <Application example 4> (Incineration residue classification system)
The processing system of FIG. 17 is an incineration residue classification system 28 using the screen device 1A of the first embodiment. Here, the object to be treated P is an incineration residue incinerated in a refuse incinerator 29 such as a stoker oven.
The incineration residue classification system 28 receives the incinerator 29 and the incineration residue in which the waste is incinerated in the incinerator 29 and receives the incinerated residue and cools it in water or the like, and conveys it with a conveying device (for example, a belt conveyor, a screw conveyor, a scraper). At least a ashing device 30 for discharging by a conveyor, a flight conveyor, etc., and a screen device 10A for receiving and classifying the incineration residue discharged by the ashing device 30. The screen device 10A may be further arranged below the screen device 10A to perform further classification.
The screen device 10A is arranged so that the screen surface S faces upward and is inclined downward from the "other end" to the "one end". Then, the "other end" receives the incineration residue discharged by the ash extraction device 30. The incineration residue, which is the object to be treated P received at the "other end", is classified while sliding down the screen surface S by its own weight.
Below the screen device 10A, a classification container 32 capable of separating and storing at least three classified products of a liquid, a small diameter product and a large diameter product is arranged. The large-diameter object is highly likely to be an incombustible material such as metal, but the small-diameter object is often an incombustible unburned object. Therefore, the control device 6 controls the conveyor device 33 such as a belt conveyor at any time. Then, the small-diameter product is put into the waste hopper 31 and burned again in the waste incinerator 29. The classified liquid is waste liquid, but is reused, for example, by spraying the exhaust gas to cool the exhaust gas generated in the refuse incinerator 29.

制御装置６は、スクリーン装置１Ａが受ける焼却残渣の種類に応じて、上記第一の間隔Ｇａを制御する。例えば、当該焼却残渣に未燃分が多い場合、第一の間隔Ｇａを第二の間隔Ｇｂより大きくするよう、第一のスライド部５ａを＋ｚ方向（プラスｚ方向）に移動する。一方、制御装置６は、当該焼却残渣に不燃物（金属等）が多い場合、第一の間隔Ｇａを上記所定距離まで狭めるよう、第三のスライド部５ｃを−ｚ方向（マイナスｚ方向）に移動する。なお、制御装置６は、例えば、第一の間隔Ｇａを第二の間隔Ｇｂより大きくした場合の互いの差が最大で約３０〜５０ｃｍとなるよう、第三のスライド部５ｃを＋ｚ方向（プラスｚ方向）に移動する。
すなわち、焼却残渣分級システム２８は、被処理物Ｐである焼却残渣の種類に応じて、隣り合う線材２の間隔（目開き）の大きさを、線材２の「他端」から「一端」に向かって、長さ方向に次第に大きくなるよう制御可能である。
従って、１つのスクリーン装置のみで、「他端」に供給した被処理物から高速に水分を取り除き、且つ、分級することができる。夾雑物除去システム１０は、費用対効果に優れるのみならず、分級の処理に優れた性能を発揮することができる処理システムである。 The control device 6 controls the first gap Ga according to the type of incineration residue received by the screen device 1A. For example, when the incineration residue has a large amount of unburned components, the first slide portion 5a is moved in the + z direction (plus z direction) so that the first gap Ga is larger than the second gap Gb. On the other hand, when the incineration residue contains a large amount of incombustibles (metal or the like), the control device 6 moves the third slide portion 5c in the −z direction (minus z direction) so as to narrow the first gap Ga to the predetermined distance. Moving. In addition, for example, the control device 6 sets the third slide portion 5c in the + z direction (plus) so that the maximum difference between the first gap Ga and the second gap Gb becomes about 30 to 50 cm. move in the z direction).
That is, the incineration residue classification system 28 changes the size of the interval (opening) between the adjacent wire rods 2 from “the other end” to “one end” of the wire rods 2 according to the type of the incineration residue that is the object to be treated P. It is possible to control so as to gradually increase in the length direction.
Therefore, with only one screen device, it is possible to remove moisture from the object to be processed supplied to the "other end" at high speed and perform classification. The contaminant removal system 10 is a processing system that is not only cost-effective, but can also exhibit excellent performance in classification.

なお、本応用例では、第一のスライド部５ａを備えたスクリーン装置１Ａ（第一実施形態）を用いて説明したが、第二のスライド部５ｂを備えたスクリーン装置（第一実施形態の変形例）を用いても、上述の優れた性能を備えた処理システムとなる。   In addition, although this application example demonstrated using the screen device 1A (1st embodiment) provided with the 1st slide part 5a, the screen device provided with the 2nd slide part 5b (modification of 1st embodiment). Example) also results in a processing system having the above-mentioned excellent performance.

以上、本発明の実施形態、変形例、及び応用例について図面を参照して詳述した。しかし、具体的な構成はこれら実施形態、変形例、または応用例に限定されるものではなく、本発明の要旨を逸脱しない範囲の設計変更等も含まれる。
例えば、「一端」と同様に、「他端」にもスライド部を配置し、制御装置６が第二の間隔Ｇｂを変更可能としてもよい。この場合においても、制御装置６が第一の間隔Ｇａを第二の間隔Ｇｂより大きくすれば、上述の効果が得られるのみならず、線材２の長さ方向における目開きのバリエーションを増加させることができるので、より優れたスクリーン装置または当該スクリーン装置を備えた処理システムとすることができる。また、この場合、第一の間隔Ｇａと第二の間隔Ｇｂを同一にする制御も容易である。 The embodiments, modifications, and applications of the present invention have been described above in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, modified examples, or application examples, and includes design changes and the like within the scope not departing from the gist of the present invention.
For example, like the “one end”, the slide unit may be arranged at the “other end” so that the control device 6 can change the second gap Gb. Also in this case, if the control device 6 makes the first gap Ga larger than the second gap Gb, not only the above-described effect is obtained but also the variation of the openings in the length direction of the wire 2 is increased. Therefore, a more excellent screen device or a processing system equipped with the screen device can be provided. In this case, it is also easy to control the first gap Ga and the second gap Gb to be the same.
