Description

本発明は、下水汚泥や掘削残渣、泥炭等に代表される液状物質と固形物質との混合体（以後、含液物質という。）を貯留可能な貯留装置に関するものである。より詳しくは、含液物質排出口の開閉ゲートが、スライドゲートやカットゲート等のゲートであるホッパーに関するものである。   The present invention relates to a storage device capable of storing a mixture of a liquid substance and a solid substance represented by sewage sludge, excavation residue, peat and the like (hereinafter referred to as a liquid-containing substance). More specifically, the present invention relates to a hopper in which the open / close gate of the liquid-containing substance discharge port is a gate such as a slide gate or a cut gate.

この種の含液物質貯留装置においては、含液物質の排出口が、スライドゲートやカットゲート等のゲートで、開閉される。そして、排出口を形成する周壁とゲート上側表面との間（以下、単に隙間ともいう。）は、周壁に取り付けられ下方へ延出する平板状のシール材で塞がれている（例えば、特許文献１参照。）。   In this type of liquid-containing substance storage device, the liquid-containing substance discharge port is opened and closed by a gate such as a slide gate or a cut gate. A space between the peripheral wall forming the discharge port and the gate upper surface (hereinafter also simply referred to as a gap) is closed by a flat plate-like sealing material attached to the peripheral wall and extending downward (for example, a patent) Reference 1).

しかしながら、この平板状のシール材は、含液物質が隙間から漏れるのを防止するためのものであるため、かかる隙間の長さよりも長くなっている。したがって、常時曲がった状態（変形）となり、この状態でくせが付くため、シール性能が低下するおそれある。また、常時開閉ゲートと接触した状態にあり、この接触状態でゲートが開閉するため、すぐに摩耗してシール性能が低下するおそれがある。シール性能が低下すれば、当然、含液物質が隙間から漏れることになる。
特開平８−２５３２９２号公報（段落０００７、図５） However, since this flat sealing material is for preventing the liquid-containing substance from leaking from the gap, it is longer than the length of the gap. Therefore, it will be in the state (deformation) always bent, and since it becomes habit in this state, there exists a possibility that sealing performance may fall. Further, since the gate is always in contact with the open / close gate, and the gate opens and closes in this contact state, there is a possibility that the seal performance is deteriorated due to wear immediately. If the sealing performance is lowered, naturally, the liquid-containing substance leaks from the gap.
JP-A-8-253292 (paragraph 0007, FIG. 5)

次に、本発明の実施の形態を説明する。
図１に示すように、本形態の含液物質貯留装置たるホッパー装置１は、含液物質Ｐの排出口２を形成する周壁４と、排出口２を開閉する開閉ゲート、図示例では一対（紙面左右にそれぞれ１つづつ）のカットゲート３，３と、周壁４に備えられて、この周壁４とカットゲート３，３の上側表面３ａとの間を塞ぐシール材１０と、を主に有する。 Next, an embodiment of the present invention will be described.
As shown in FIG. 1, a hopper device 1 as a liquid-containing substance storage device according to this embodiment includes a peripheral wall 4 that forms a discharge port 2 for a liquid-containing material P, an open / close gate that opens and closes the discharge port 2, and a pair ( Cut gates 3, 3 (one on each of the left and right sides of the paper) and a sealing material 10 provided on the peripheral wall 4 and closing the space between the peripheral wall 4 and the upper surface 3 a of the cut gate 3, 3. .

本形態において、一対のカットゲート３，３は、基端部３Ａ，３Ａに、それぞれ伸縮自在なシリンダ５，５の一端部が接続されている。このシリンダ５，５の他端部は、それぞれ周壁４，４に取り付けられている。本シリンダ５，５が収縮すると、カットゲート３，３が、それぞれ外方向（Ｏ方向）に移動して、排出口２が開く。他方、本シリンダ５，５が伸張すると、カットゲート３，３が、それぞれ内方向（Ｃ方向）に移動して、排出口２が閉じる。   In this embodiment, the pair of cut gates 3 and 3 are connected to the base end portions 3A and 3A, respectively, at one end portions of the extendable cylinders 5 and 5, respectively. The other ends of the cylinders 5 and 5 are attached to the peripheral walls 4 and 4, respectively. When the cylinders 5 and 5 are contracted, the cut gates 3 and 3 are moved outward (O direction), and the discharge port 2 is opened. On the other hand, when the cylinders 5 and 5 are extended, the cut gates 3 and 3 are moved inward (C direction), and the discharge port 2 is closed.

一方、シール材１０は、図２に示すように、周壁４の先端部４Ａから下方へ延出する平板状の下方延出片１１と、この下方延出片１１の下端部から内方（排出口２の中心側に向かう方向）へ延出する平板状の内方延出片１２と、から主になる。シール材１０は、周壁４の先端部４Ａに、直接的に、又は図示例のように周壁４の先端部４Ａに沿う補強板７を介在させて間接的に、例えば、ボルト８で締結するなどして、取り付けることができる。   On the other hand, as shown in FIG. 2, the sealing material 10 includes a flat plate-like downwardly extending piece 11 extending downward from the front end portion 4 </ b> A of the peripheral wall 4 and an inner side (exhaust from the lower end portion of the downwardly extending piece 11. Mainly from the flat inwardly extending piece 12 extending in the direction toward the center of the outlet 2. The sealing material 10 is fastened directly to the front end portion 4A of the peripheral wall 4 or indirectly with, for example, a bolt 8 with a reinforcing plate 7 interposed along the front end portion 4A of the peripheral wall 4 as illustrated in the figure. And can be attached.

シール材１０の内方延出片１２は、可とう性を有していて、含液物質Ｐが貯留装置内に貯留された時に内方延出片１２上側表面に作用する圧力によってカットゲート３の上側表面３ａに接触可能な材質を選定する。したがって、図４に示すように、含液物質Ｐが貯留されると、内方延出片１２は下方に押され、内方延出片１２の下側表面（カットゲート３側の表面）１２ａとカットゲート３の上側表面（シール材１０側の表面）３ａとが密着することになる。この密着により、含液物質Ｐが周壁４とカットゲート３の上側表面３ａとの間から漏れるおそれがなくなる。   The inwardly extending piece 12 of the sealing material 10 has flexibility, and the cut gate 3 is caused by pressure acting on the upper surface of the inwardly extending piece 12 when the liquid-containing substance P is stored in the storage device. A material that can contact the upper surface 3a is selected. Therefore, as shown in FIG. 4, when the liquid-containing substance P is stored, the inwardly extending piece 12 is pushed downward, and the lower surface (the surface on the cut gate 3 side) 12a of the inwardly extending piece 12 And the upper surface (the surface on the sealing material 10 side) 3a of the cut gate 3 are brought into close contact with each other. This close contact eliminates the possibility that the liquid-containing substance P leaks from between the peripheral wall 4 and the upper surface 3a of the cut gate 3.

もっとも、この密着時においても、内方延出片１２の下側表面１２ａとカットゲート３の上側表面３ａとの間には、ごく微量ではあるが、含液物質Ｐが介在することになる（介在する含液物質は、符号Ｐａで示す。）。そして、この含液物質Ｐａがいわば潤滑オイルとしての機能をはたすことになるため、含液物質Ｐの排出時において、内方延出片１２の下側表面１２ａとカットゲート３の上側表面３ａとが密着した状態でカットゲート３を開いたとしても、大きな摩擦が生じることはない。したがって、シール材１０（内方延出片１２）がすぐに摩耗してシール性能が低下するおそれはない。   However, even at the time of this close contact, the liquid-containing substance P is present between the lower surface 12a of the inwardly extending piece 12 and the upper surface 3a of the cut gate 3 although it is a very small amount ( The intervening liquid-containing substance is indicated by the symbol Pa). Since the liquid-containing substance Pa functions as a lubricating oil, when the liquid-containing substance P is discharged, the lower surface 12a of the inwardly extending piece 12 and the upper surface 3a of the cut gate 3 Even if the cut gate 3 is opened in the state of being in close contact with each other, no significant friction is generated. Therefore, there is no possibility that the sealing material 10 (inwardly extending piece 12) is worn out immediately and the sealing performance is deteriorated.

一方、シール材１０の内方延出片１２は、含液物質Ｐが内方延出片１２上側表面から除かれた場合において、図２に示すように、カットゲート３の上側表面３ａから離間する復元性も有する。したがって、常時曲がった状態（変形）となり、この状態でくせが付くということがないため、シール材１０の周壁４外部へのめくり上がり等によってシール性能が低下するおそれがない。また、カットゲート３を閉じる場合においては、内方延出片１２がカットゲート３の上側表面３ａから離間していることになるため、摩擦が生じることはない。したがって、シール材１０（内方延出片１２）がすぐに摩耗してシール性能が低下するおそれもない。
なお、カットゲート３を閉じる場合においては、内方延出片１２の下側表面１２ａとカットゲート３の上側表面３ａとの間に、含液物質Ｐａが介在しないため、内方延出片１２がカットゲート３の上側表面３ａから離間していないと、極めて大きな摩擦・摩耗が生じることになる。 On the other hand, the inwardly extending piece 12 of the sealing material 10 is separated from the upper surface 3a of the cut gate 3 as shown in FIG. 2 when the liquid-containing substance P is removed from the upper surface of the inwardly extending piece 12. It also has a resilience to Therefore, since it is always bent (deformed) and does not become wrinkled in this state, there is no possibility that the sealing performance is deteriorated due to the sealing material 10 being turned to the outside of the peripheral wall 4 or the like. Further, when the cut gate 3 is closed, the inwardly extending piece 12 is separated from the upper surface 3a of the cut gate 3, so that friction does not occur. Therefore, there is no possibility that the sealing material 10 (inwardly extending piece 12) is worn out immediately and the sealing performance is deteriorated.
When the cut gate 3 is closed, since the liquid-containing substance Pa is not interposed between the lower surface 12a of the inward extending piece 12 and the upper surface 3a of the cut gate 3, the inward extending piece 12 If they are not separated from the upper surface 3a of the cut gate 3, extremely large friction and wear will occur.

本実施の形態において、内方延出片１２の素材は、特に限定されない。以上のような可とう性及び復元性を有するのであれば、例えば、スチール、アルミ等の金属、天然ゴム、合成ゴム、再生ゴム等のゴム類が好ましい。ゴム類の中でもネオプレンゴム及びクロロプレンゴムの少なくともいずれか一方であることが特に好ましい。カットゲート３は、強度の観点から、通常金属製であるため、内方延出片１２を金属製とするよりもゴム製とした方が、両者の密着性に優れ、また、カットゲート３の磨耗が減少する。特に、ネオプレンゴム及びクロロプレンゴムは、耐変形性及び耐摩耗性の観点においても、優れる。   In the present embodiment, the material of the inwardly extending piece 12 is not particularly limited. As long as it has the above flexibility and resilience, for example, metals such as steel and aluminum, and rubbers such as natural rubber, synthetic rubber and recycled rubber are preferable. Among the rubbers, at least one of neoprene rubber and chloroprene rubber is particularly preferable. Since the cut gate 3 is usually made of metal from the viewpoint of strength, it is better to make the inwardly extending piece 12 made of rubber than the metal made of rubber. Wear is reduced. In particular, neoprene rubber and chloroprene rubber are excellent in terms of deformation resistance and wear resistance.

ネオプレンゴムやクロロプレンゴム等のゴムは、内方延出片１２の全てを形成するように使用してもよいが、例えば、図７の（ａ）に示すように、内方延出片１２の下側端部１２Ａのみを形成するように使用することや、図７の（ｂ）に示すように、内方延出片１２の先端部１２Ｂのみを形成するように使用することなどもできる。これら一部使用の形態は、原材料コストの削減や耐久性の向上に資する場合がある。   A rubber such as neoprene rubber or chloroprene rubber may be used so as to form all of the inwardly extending piece 12. For example, as shown in FIG. It can also be used to form only the lower end 12A, or it can be used to form only the tip 12B of the inwardly extending piece 12 as shown in FIG. 7B. These partially used forms may contribute to reduction of raw material costs and improvement of durability.

本内方延出片１２の内方への延出長さＬ（図５参照）は、３０〜１００ｍｍにするのが好ましく、５０〜７０ｍｍにするのがより好ましい。延出長さＬが短すぎると、内方延出片１２の下側表面１２ａとカットゲート３の上側表面３ａとが十分に密着しないおそれがある。他方、延出長さＬが長すぎると、カットゲート３を開く場合において、内方延出片１２の先端部１２Ｂを巻き込んでしまうおそれがある。   The inward extending length L (see FIG. 5) of the inwardly extending piece 12 is preferably 30 to 100 mm, and more preferably 50 to 70 mm. If the extension length L is too short, the lower surface 12a of the inwardly extending piece 12 and the upper surface 3a of the cut gate 3 may not be sufficiently adhered. On the other hand, if the extension length L is too long, the tip 12B of the inwardly extending piece 12 may be caught when the cut gate 3 is opened.

ここで、本明細書において、内方延出片１２の延出長さＬとは、図５に示すように、内方延出片１２の上側表面における下方延出片１１との境界点から内方延出片１２の先端縁までを意味する。   Here, in the present specification, the extension length L of the inwardly extending piece 12 refers to a boundary point with the lower extending piece 11 on the upper surface of the inwardly extending piece 12, as shown in FIG. It means up to the tip edge of the inwardly extending piece 12.

本内方延出片１２は、図５の（ａ）に示すように、水平面Ｅに対して平行であっても、図５の（ｂ）に示すように、水平面Ｅに対してホッパー底部に向かって所定の角度をもっていてもよい。ただし、水平面Ｅと内方延出片１２とのなす角度Ｎが、０〜４０°であるのが好ましく、０〜２０°であるのがより好ましい（図５の（ａ）は角度Ｎが０°の場合を、図５の（ｂ）は角度Ｎが３０°の場合を、それぞれ例示している。）。角度Ｎが０°を下回ると、つまりマイナスであると、含液物質Ｐの貯留時に、内方延出片１２のカットゲート３側への変形量が多くなり、内方延出片１２の早期劣化につながるおそれがある。他方、角度Ｎが４０°を上回ると、カットゲート３を開く場合において、内方延出片１２の先端部１２Ｂを巻き込んでしまうおそれがある。   Even if the inwardly extending piece 12 is parallel to the horizontal plane E as shown in FIG. 5A, the inner extending piece 12 is located at the bottom of the hopper with respect to the horizontal plane E as shown in FIG. You may have a predetermined angle toward. However, the angle N formed by the horizontal plane E and the inwardly extending piece 12 is preferably 0 to 40 °, and more preferably 0 to 20 ° (in FIG. 5A, the angle N is 0). (B) in FIG. 5 illustrates the case where the angle N is 30 °. When the angle N is less than 0 °, that is, minus, when the liquid-containing substance P is stored, the amount of deformation of the inwardly extending piece 12 toward the cut gate 3 increases, and the inwardly extending piece 12 becomes early. May lead to deterioration. On the other hand, if the angle N exceeds 40 °, the tip 12B of the inwardly extending piece 12 may be caught when the cut gate 3 is opened.

本発明者らが試験したところによると、シール材１０の全てをネオプレンゴム製とし、内方延出片１２の角度Ｎを０°とした場合において、内方延出片１２の厚さを６ｍｍとし、かつ下方延出片１１の厚さを１０ｍｍとすると、密着性向上、巻き込み防止等の全ての観点において、最も優れることを知見している。   According to a test conducted by the present inventors, when all of the sealing material 10 is made of neoprene rubber and the angle N of the inwardly extending piece 12 is 0 °, the thickness of the inwardly extending piece 12 is 6 mm. In addition, when the thickness of the downward extending piece 11 is 10 mm, it has been found that it is the most excellent in all aspects such as improvement in adhesion and prevention of entrainment.

本シール材１０について、下方延出片１１と内方延出片１２とは、一体成形とすることもできる。ただし、一体成形とすると、新たな金型が必要となりコストが向上するなどの問題がある場合は、下方延出片１１の下端部に、内方延出片１２の基端部を貼り合わせるのが好ましい。そして、この場合は、図６に示すように、シール材１０の両表面を、少なくとも両延出片１１，１２の貼り合せ部１３が覆われるように、ゴム等からなる補助材１４，１４を貼り付けるなどして、覆うのが好ましい。これにより、貼り合せ部１３が補強され、また、貼り合せ部１３からの含液物質Ｐの漏出が防止される。   With respect to the sealing material 10, the downwardly extending piece 11 and the inwardly extending piece 12 can be integrally formed. However, in the case of integral molding, if there is a problem that a new mold is required and the cost is increased, the base end portion of the inwardly extending piece 12 is bonded to the lower end portion of the downwardly extending piece 11. Is preferred. In this case, as shown in FIG. 6, auxiliary materials 14, 14 made of rubber or the like are provided so that both surfaces of the sealing material 10 are covered with at least the bonding portions 13 of the extended pieces 11, 12. It is preferable to cover it by pasting. Thereby, the bonding part 13 is reinforced and leakage of the liquid-containing substance P from the bonding part 13 is prevented.

同様に、排出口２の断面形状が、正方形、長方形等の多角形である場合は、図３に示すように、相互に隣接する内方延出片１２，１２の端部同士を、貼り合せ部１７で貼り合せ、また、相互に隣接する下方延出片１１，１１の端部同士を、貼り合せ部１８で貼り合せるとよい。この際、下方延出片１１，１１は、この下方延出片１１，１１を挟んで周壁４と対向するように配置された補強材９によって、補強することもできる。貯留する含液物質の含液率、ホッパーの容量・形状によっては、周壁全てに内方延出片を設ける必要はなく、例えば、開閉ゲートの開閉方向と直角側の周壁だけに設けるようにしてもよい。   Similarly, when the cross-sectional shape of the discharge port 2 is a polygon such as a square or a rectangle, the ends of the inwardly extending pieces 12 and 12 adjacent to each other are bonded together as shown in FIG. It is preferable that the end portions of the downwardly extending pieces 11 and 11 adjacent to each other are bonded to each other at the bonding portion 18. At this time, the downwardly extending pieces 11, 11 can be reinforced by the reinforcing material 9 disposed so as to face the peripheral wall 4 with the downwardly extending pieces 11, 11 being sandwiched therebetween. Depending on the liquid content of the liquid material to be stored and the capacity and shape of the hopper, it is not necessary to provide inwardly extending pieces on all the peripheral walls. Also good.

ところで、本形態のように、排出口２の開閉ゲートがカットゲート３である場合においては、周壁４とカットゲート３の上側表面３ａとの離間距離が、なるべく変化しないようにするのが好ましく、実質的に一定となるようにするのがより好ましい。離間距離が実質的に一定となるようにすると、カットゲート３の開閉時において、内方延出片１２の撓み量が一定となり、内方延出片１２の耐久性が向上する。また、下方延出片１１の長さＭ（図５参照）を短くし、あるいは図８に示すように、なくす（設けない）ことができる。なお、図８においては、補強板７を略Ｌ字状とし、この補強板７の下側表面に内方延出片１２を取り付けている。   By the way, when the open / close gate of the discharge port 2 is the cut gate 3 as in this embodiment, it is preferable that the separation distance between the peripheral wall 4 and the upper surface 3a of the cut gate 3 is not changed as much as possible. More preferably, it is substantially constant. When the separation distance is made substantially constant, the amount of bending of the inwardly extending piece 12 becomes constant when the cut gate 3 is opened and closed, and the durability of the inwardly extending piece 12 is improved. Further, the length M (see FIG. 5) of the downward extending piece 11 can be shortened or eliminated (not provided) as shown in FIG. In FIG. 8, the reinforcing plate 7 has a substantially L shape, and an inwardly extending piece 12 is attached to the lower surface of the reinforcing plate 7.

周壁４とカットゲート３の上側表面３ａとの離間距離変化の調節は、カットゲート３の回転軸６からの距離や、カットゲート３の曲率（曲がり方）・形状、周壁４の曲率・形状等を適宜設計して、調節することができる。
より具体的には、例えば、図９の（ａ）に示すように、カットゲート３の曲率を決定する中心と、側壁４の下端部４Ｂ（図１参照）の曲率を決定する中心と、カットゲート３の駆動点（回転軸）が、全て同一で符号６Ｒ（６Ｌ）で示す位置に存在したとすると、カットゲート３が開く過程においては、図９の（ｂ）から明らかなように、離間距離が常に一定となり、好ましい形態となる。 The adjustment of the change in the separation distance between the peripheral wall 4 and the upper surface 3a of the cut gate 3 includes the distance from the rotation axis 6 of the cut gate 3, the curvature (how to bend) and shape of the cut gate 3, the curvature and shape of the peripheral wall 4, etc. Can be appropriately designed and adjusted.
More specifically, for example, as shown in FIG. 9A, the center for determining the curvature of the cut gate 3, the center for determining the curvature of the lower end portion 4B of the side wall 4 (see FIG. 1), and the cut Assuming that the driving points (rotating shafts) of the gates 3 are all the same and are located at the positions indicated by the reference numerals 6R (6L), as shown in FIG. The distance is always constant, which is a preferred form.

これに対して、従来一般的であったように、カットゲート３の曲率を決定する中心とカットゲート３の駆動点が一致しないと、例えば、カットゲート３の曲率を決定する中心が先の形態と同様である場合において、図１０の（ａ）に示すように、左右両カットゲート３，３が当接する中心ラインＣＥ上にカットゲート３の駆動点（回転軸）６Ｃがあるとすると、図１０の（ｂ）に示すように、カットゲート３が開く過程においては、カットゲート３の軌跡が上方に距離Ｈだけ移動するため、この移動に合わせて、シール材１０の内方延出片１２も上方に距離Ｈだけ移動しなければならないことになる。この移動は、例えば、機械的に行うこともできるが、コストの観点から、通常は、下方延出片１１の長さを調節し、あるいはたわませて（撓ませて）、行うことになる。   On the other hand, if the center for determining the curvature of the cut gate 3 and the drive point of the cut gate 3 do not coincide with each other, as in the conventional case, for example, the center for determining the curvature of the cut gate 3 is the previous form. 10 (a), if the drive point (rotation axis) 6C of the cut gate 3 is on the center line CE where the left and right cut gates 3, 3 abut, as shown in FIG. 10 (b), in the process of opening the cut gate 3, the trajectory of the cut gate 3 moves upward by a distance H. Accordingly, the inwardly extending piece 12 of the sealing material 10 is moved in accordance with this movement. Must also move upward by a distance H. This movement can be performed, for example, mechanically, but from the viewpoint of cost, it is usually performed by adjusting the length of the downwardly extending piece 11 or by bending (deflecting). .

また、含液物質Ｐの重さに耐えうる強度を確保するためや、含液物質Ｐが漏出するのを防止するため、などから、例えば、図中点線で示すように、カットゲート３の中央部３Ｂを直線状とし、カットゲート３の駆動点の延長線とカットゲート３が交わる位置より円弧が開始される構造が好ましい。   Further, in order to ensure the strength that can withstand the weight of the liquid-containing substance P or to prevent the liquid-containing substance P from leaking out, for example, as shown by the dotted line in the figure, the center of the cut gate 3 It is preferable that the portion 3B is linear and a circular arc is started from the position where the extended line of the drive point of the cut gate 3 and the cut gate 3 intersect.

（その他）
本発明が対象とする含液物質Ｐとしては、例えば、下水汚泥（高分子系、石灰系等）、油かす、掘削残渣等を例示することができる。ただし、含液率が７６〜８４質量％の、例えば、下水汚泥が対象であるのが好ましい。含液率が７６質量％以上と高いと、周壁４とゲート上側表面３ａとの間（隙間）から含液物質Ｐが漏れやすくなるため、本発明の効果がいかんなく発揮される。もっとも、含液率が８４質量％を超えると、もはや液体と同様の状態であるため、含液率が８４質量％以下である場合の方が、本発明の適用上、好ましい。 (Other)
Examples of the liquid-containing substance P targeted by the present invention include sewage sludge (polymer-based, lime-based, etc.), oil cake, excavation residue, and the like. However, for example, sewage sludge having a liquid content of 76 to 84% by mass is preferred. When the liquid content is as high as 76% by mass or more, the liquid-containing substance P is likely to leak from between the peripheral wall 4 and the gate upper surface 3a (gap), so that the effects of the present invention are exhibited. However, when the liquid content exceeds 84% by mass, the liquid is no longer in the same state as the liquid. Therefore, the case where the liquid content is 84% by mass or less is preferable for the application of the present invention.

また、本ホッパー装置１への含液物質Ｐの搬送方法は、特に限定されない。ただし、含液物質Ｐがポンプ圧送される場合には、含液物質Ｐ中の空気が分離し、圧密を受けると同時に含液物質Ｐの流動化現象が発生し、液状化するため、本発明の効果がいかんなく発揮される。ポンプ圧送された場合、含液物質Ｐの流動性が高く、隙間から含液物質Ｐが漏れやすくなるためである。   Moreover, the conveyance method of the liquid-containing substance P to this hopper apparatus 1 is not specifically limited. However, when the liquid-containing substance P is pumped, the air in the liquid-containing substance P is separated and subjected to consolidation, and at the same time, the fluidizing phenomenon of the liquid-containing substance P occurs and liquefies. The effect of is fully demonstrated. This is because when the liquid is pumped, the liquid-containing substance P has high fluidity, and the liquid-containing substance P is likely to leak from the gap.

本発明は、含液物質排出口の開閉ゲートが、スライドゲートやカットゲート等のゲートである含液物質貯留装置として、適用可能である。   The present invention is applicable as a liquid-containing substance storage device in which the open / close gate of the liquid-containing substance discharge port is a gate such as a slide gate or a cut gate.
