Description

本発明は、泥水や産業廃液などの液状物を、移送するなどのために吸上げる吸上げ装置に関するものである。   The present invention relates to a suction device for sucking up liquid materials such as muddy water and industrial waste liquid for transportation.

泥水や産業廃液などの液状物を移したり、搬送などするために、それら液状物を吸上げる装置が開発されている。
例えば特許第３９２６７７７号の発明のように、螺旋状の羽根を外周に有する回転軸を回転し、羽根の回転によって液状物を吸上げ口へ送り込むような構成がある。
この泥水や産業廃液などに混ざっている成分は、必ずしも流動性の高い液状物だけとは限らず、時には岩石や鉄筋などの大きな固形物が混じっていることがある。
液状物と一緒に、これら岩石や鉄筋などを吸上げると、移送のためのホースが詰まることがあり、それらがソイルセメントなどに混ざると、その性能を低下させることになる。 In order to transfer or transport liquid substances such as muddy water and industrial waste liquid, an apparatus for sucking up the liquid substances has been developed.
For example, as in the invention of Japanese Patent No. 3926777, there is a configuration in which a rotating shaft having spiral blades on the outer periphery is rotated, and a liquid material is sent to the suction port by the rotation of the blades.
The components mixed in the muddy water and industrial waste liquid are not necessarily liquid materials with high fluidity, and sometimes large solid materials such as rocks and reinforcing bars are mixed.
If these rocks and reinforcing bars are sucked up together with the liquid material, the transfer hose may be clogged, and if they are mixed with soil cement or the like, the performance will be reduced.

このような岩石などを取り除く手段として、上記特許発明では、吸上げ口の周囲に、篭状の枠体をフィルターとして配置し、岩石や粘土などの固形物を枠体でくい止めて、吸上げ口から吸上げられないような工夫をしている。
しかしながら、篭のような多数の網目を有する枠体であると、この篭の網目に岩石や粘土成分などが詰まって、吸上げ性能が大きく低下することがある。
また、大きめの岩石などは篭状の枠体でくい止めることができるが、小さめの岩石などは篭の目を通り抜け、この小さめの岩石が吸上げ口に集まると、吸上げ口で互いに噛み合って詰まるブリッジという現象を起すことがあった。
特許第３９２６７７７号公報 As a means for removing such rocks, in the above-mentioned patented invention, a trapezoidal frame is arranged as a filter around the suction port, and solids such as rocks and clay are blocked by the frame, and the suction port The device is designed not to be sucked up.
However, in the case of a frame body having a large number of meshes, such as cocoons, rocks or clay components are clogged in the meshes of the cocoons, and the sucking performance may be greatly reduced.
Large rocks can be stopped with a bowl-shaped frame, but small rocks can pass through the eye of the coral, and when these small rocks gather at the suction port, they mesh with each other at the suction port and become clogged. There was a phenomenon called a bridge.
Japanese Patent No. 3926777

解決しようとする課題は、岩石などの固形物を取り除くとともに、吸込み口の手前で目詰まりやブリッジ現象が生じないようにし、液状物の吸上げ性能を低下させないことである。   The problem to be solved is to remove solid matter such as rocks and to prevent clogging and bridging before the suction port, and not to lower the liquid suction performance.

枠体１は、略三角形の二枚の外板２・２が、三角形の隅角部間に渡した３本の枠材３・３・３によって一体に組み上げられている。
従って、枠体１は略三角形の断面形状を備えることになる。
枠体１の三つの外周側面には、枠材３と枠材３との間に、外板２の平面と平行な丸鋼棒４が、適宜間隔づつ離れて複数本づつ固定されている。
つまり、この隣り合う丸鋼棒４間には、スリット５がそれぞれ形成されることになる。
三つの外周側面のうち、ひとつ（図３で下側面）は、ヒンジ結合されて、開閉可能となっている。 Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.
<1> Frame Body The suction device A according to the present invention includes a scraper plate 10 that is rotationally driven, a spiral plate 11, and a suction port 9 in the frame body 1.
In the frame 1, two substantially triangular outer plates 2, 2 are integrally assembled by three frame members 3, 3, 3 that are passed between the corners of the triangle.
Therefore, the frame 1 has a substantially triangular cross-sectional shape.
On the three outer peripheral side surfaces of the frame body 1, a plurality of round steel bars 4 parallel to the plane of the outer plate 2 are fixed between the frame material 3 and the frame material 3 at an appropriate interval.
That is, the slits 5 are formed between the adjacent round steel bars 4.
Of the three outer peripheral side surfaces, one (the lower side surface in FIG. 3) is hinged and can be opened and closed.

＜２＞駆動源
枠体１内には、一方の外板２の外側に、駆動源となる駆動モーター６が取付けられている。
駆動モーター６によって回転する回転軸７が、２枚の外板２・２を貫通して、その外板２・２間に渡されている。
回転軸７が貫通する位置は、外板２の三隅角部から等距離の位置である。 <2> Drive Source A drive motor 6 serving as a drive source is attached to the outside of one outer plate 2 in the frame body 1.
A rotating shaft 7 rotated by the drive motor 6 passes through the two outer plates 2 and 2 and is passed between the outer plates 2 and 2.
The position through which the rotation shaft 7 penetrates is a position equidistant from the three corners of the outer plate 2.

＜３＞吸上げ口
２枚の外枠２のうち、一方の外枠２を貫通して、吸上げパイプ８が枠体１の内側に突出し、吸上げ口９が開口している。
吸上げパイプ８の先端は、回転軸７側に吸上げ口９が開口するようテーパー状に切断されている。
すなわち図２で言えば、吸上げパイプ８の先端部は、先端に行くに従って徐々に上側部分のみに細くなっている。 <3> Suction port One of the two outer frames 2 passes through one outer frame 2, the suction pipe 8 protrudes to the inside of the frame 1, and the suction port 9 opens.
The tip of the suction pipe 8 is cut into a taper shape so that the suction opening 9 opens on the rotating shaft 7 side.
That is, in FIG. 2, the tip of the suction pipe 8 is gradually narrowed only to the upper part as it goes to the tip.

＜４＞掻き板
前記した外板２・２の間に渡された回転軸７の外周に、複数枚の掻き板１０が適宜間隔づつ離れて固定されている。
この適宜間隔づつというのは、前記した隣合う丸鋼棒４・４間の間隔と同一であって、その固定の位置は、枠体１の丸鋼棒４・４間のスリット５に対応する位置である。
掻き板１０は、平板状の部材であって、隣合う掻き板１０は、その伸びる方向の角度が９０度づつ異なって、回転軸７に固定されている。（図４）
掻き板１０のうち、吸上げパイプ８から離隔した位置に取付けられた掻き板１０ａの回転軸７から先端までの長さは、回転軸７から外板２の隅角部の枠材３までよりも短く、回転軸７から外板２の三辺の中間部までよりも長く形成されている。
このことにより、回転軸７とともに掻き板１０ａが回転すると、枠材３に接触しないが、その一回転の中の一部で、丸鋼棒４・４間のスリット５から、外板２の外周よりも外、つまりは枠体１の外側に突出することになる。（図３）
掻き板１０のうち、吸上げパイプ８近傍側に取付けられた掻き板１０ｂ・１０ｃは、前記した掻き板１０ａよりも短く、回転軸７とともに回転するとき、その先端が吸上げ口９近くを通過するようになっている。 <4> Scraping plate A plurality of scraping plates 10 are fixed to the outer periphery of the rotary shaft 7 passed between the outer plates 2 and 2 at appropriate intervals.
This proper interval is the same as the interval between the adjacent round steel bars 4 and 4, and the fixing position corresponds to the slit 5 between the round steel bars 4 and 4 of the frame 1. Position.
The scraper plate 10 is a flat plate-like member, and the adjacent scraper plates 10 are fixed to the rotary shaft 7 at different angles in the extending direction by 90 degrees. (Fig. 4)
Of the scraper plate 10, the length from the rotation shaft 7 to the tip of the scraper plate 10 a mounted at a position separated from the suction pipe 8 is longer than the frame material 3 at the corner of the outer plate 2 from the rotation shaft 7. Is also shorter than the rotation shaft 7 to the middle part of the three sides of the outer plate 2.
As a result, when the scraper plate 10a rotates together with the rotating shaft 7, it does not come into contact with the frame member 3, but the outer periphery of the outer plate 2 from the slit 5 between the round steel rods 4 and 4 in a part of the rotation. It protrudes outside, that is, outside the frame 1. (Figure 3)
Of the scraper plate 10, scraper plates 10 b and 10 c attached to the vicinity of the suction pipe 8 are shorter than the aforementioned scraper plate 10 a, and when rotating together with the rotary shaft 7, the tip thereof passes near the suction port 9. It is supposed to be.

＜５＞螺旋板
前記した複数本の隣合う掻き板１０・１０の間には、螺旋板１１が固定されている。
螺旋板１１は、液状物Ｂを吸上げ口９側に送る部材であって、回転軸７が回転することにより、吸上げ口９側に液状物Ｂを送るよう傾いて固定されている。
螺旋板１１は、回転軸７の軸方向に離れて、その回転軸７の外周に対して、順に９０度づつ固定位置を変えて、固定してある。（図５）
要するに、螺旋板１１は、液状物Ｂを送ることが出来ればよく、螺旋スクリュー翼と同様の作用を果たすものなら、どのような形状や構成のものでよい。
実施例では、螺旋板１１は平板状のものを使用したが、スクリューのように板１１自体にヒネリを与えたような板材も使用可能である。 <5> Spiral plate A spiral plate 11 is fixed between the plurality of adjacent scraping plates 10 and 10 described above.
The spiral plate 11 is a member that sends the liquid material B to the suction port 9 side, and is tilted and fixed so that the liquid material B is sent to the suction port 9 side as the rotating shaft 7 rotates.
The spiral plate 11 is fixed by changing the fixing position by 90 degrees in order with respect to the outer periphery of the rotating shaft 7 away from the rotating shaft 7 in the axial direction. (Fig. 5)
In short, the spiral plate 11 only needs to be able to feed the liquid B, and may have any shape or configuration as long as it can perform the same function as the spiral screw blade.
In the embodiment, a flat plate is used as the spiral plate 11, but a plate material in which the plate 11 itself is slid like a screw can also be used.

＜６＞吸上げ作動
図６に示すように、以上のように構成した吸上げ装置Ａにホース１２を繋ぎ、液状物Ｂの中に沈める。
駆動モーター６を駆動して、回転軸７を回転し、螺旋板１１を回転し、液状物Ｌを吸上げ口９側に送る。
吸上げ口９に入った液状物Ｂは、ホース１２の中を搬送され、地上のダンプカー１３などに送られる。
吸上げ口９は、枠体１によって囲まれているため、枠体１のスリット５によって岩石などの侵入が妨げられている。
このスリット５に小石や粘土が詰まっても、掻き板１０ａがスリット５から突出してそれらを掻き落とすため、液状物Ｂの流入が妨げられることがない。
また、吸上げ口９近くを、掻き板１０ｂ・１０ｃの先端部が通過するため、吸上げ口９にて小石などが噛み合っても、これを掻き板１０ｂ・１０ｃが掻き崩して、吸上げ口９が塞がれることがない。 <6> Suctioning operation As shown in FIG. 6, the hose 12 is connected to the suctioning device A configured as described above and submerged in the liquid B.
The drive motor 6 is driven, the rotary shaft 7 is rotated, the spiral plate 11 is rotated, and the liquid material L is sent to the suction port 9 side.
The liquid B entering the suction port 9 is conveyed through the hose 12 and sent to the dump truck 13 or the like on the ground.
Since the suction port 9 is surrounded by the frame body 1, intrusion of rocks or the like is prevented by the slits 5 of the frame body 1.
Even if the slits 5 are clogged with pebbles or clay, the scraping plate 10a protrudes from the slits 5 and scrapes them off, so that the inflow of the liquid material B is not hindered.
Further, since the tip portions of the scraping plates 10b and 10c pass near the suction port 9, even if pebbles and the like are engaged with each other at the suction port 9, the scraping plates 10b and 10c are scraped, and the suction port 9 is not blocked.

＜他の実施の形態＞
以上の実施の形態では、掻き板１０と螺旋板１１の双方を採用したが、掻き板１０に螺旋板の機能も兼用させ、掻き板１０自体を傾斜して固定、或いはスクリュー状にヒネリを与えて、掻き落とす作用と、液状物Ｂを送る作用の双方を行えるようにしてもよい。 <Other embodiments>
In the above embodiment, both the scraper plate 10 and the spiral plate 11 are employed. However, the scraper plate 10 is also used as a spiral plate, and the scraper plate 10 is tilted and fixed, or is given a screw shape. Thus, both the action of scraping off and the action of feeding the liquid B may be performed.
