Description
本発明は、下水処理施設の汚泥掻き寄せ機などに用いられる、樹脂製のチェンに関するものである。 The present invention relates to a resin chain used in a sludge scraper or the like of a sewage treatment facility.
汚泥掻き寄せ機は、下水処理施設の沈澱池において、チェンのアタッチメントに取り付けられるフライト（汚泥掻き寄せ板）を、チェンを駆動することにより動かし、汚泥を掻き寄せるものである。 The sludge scraper moves the flight (sludge scraper) attached to the chain attachment in the sedimentation pond of the sewage treatment facility by driving the chain to scrape the sludge.
チェンは、リンク本体を相当数連結ピンで連結し、つなぎ合わせて組み立てられる。外側に配置されるリンクプレートと内側に配置されるリンクプレートを別部材で構成して組み立てる形式のチェンもあるが、本発明は、樹脂製の同一形状のリンクをつなぎ合わせるタイプのチェンについてのものである。 The chain is assembled by connecting and linking the link bodies with a considerable number of connecting pins. Although there is a chain of a type in which the link plate arranged on the outside and the link plate arranged on the inside are constructed by separate members, the present invention relates to a chain of a type in which links of the same shape made of resin are connected. It is.
リンク本体８０は、図３に示すようなものである。リンク本体８０は、その長さ方向一方の端部に、ピン挿入孔８６を有するバレル部８２があり、他方の端部には、ピン挿入孔８８を有する一対のピンリンク部８４がある。バレル部８２の幅は、一対のピンリンク部８４の間の空隙と略同一に構成される。リンク本体８０がこのように構成されることにより、リンク本体８０のバレル部８２を他のリンク本体８０の一対のピンリンク部８４間の空隙に挟み連結ピンで連結することが可能となる。
また、リンク本体８０は、図３（ｂ）に示すように、スプロケットに係合する部位である、ノッチ部９０を有する。
そして、また、リンク本体８０は、アタッチメントを取り付けるアタッチメント取付用孔９２を有し、リンク本体８０の上面（図３（ａ）が表す面）のアタッチメント取付用孔９２のリンク本体８０の幅方向の両側には、樹脂成形の成形上、窪み部９４が設けられている。
The link body 80 is as shown in FIG. The link body 80 has a barrel portion 82 having a pin insertion hole 86 at one end in the length direction, and a pair of pin link portions 84 having a pin insertion hole 88 at the other end. The width of the barrel portion 82 is configured to be substantially the same as the gap between the pair of pin link portions 84. By configuring the link main body 80 in this way, the barrel portion 82 of the link main body 80 can be sandwiched in a gap between a pair of pin link portions 84 of the other link main body 80 and connected by a connecting pin.
Moreover, the link main body 80 has the notch part 90 which is a site | part engaged with a sprocket, as shown in FIG.3 (b).
Further, the link body 80 has an attachment mounting hole 92 for mounting an attachment, and the attachment body mounting hole 92 on the upper surface (the surface shown in FIG. 3A) of the link body 80 in the width direction of the link body 80. On both sides, recesses 94 are provided for resin molding.
以上のような、リンク本体８０を相当数連結することにより、汚泥掻き寄せ機に用いられるチェンは構成されていた。 The chain used for the sludge scraper has been configured by connecting a considerable number of the link main bodies 80 as described above.
汚泥掻き寄せ機は、頻繁に運転する必要がないため、場合によっては数週間稼働させないことがある。 The sludge scraper does not need to be operated frequently, so it may not be operated for several weeks in some cases.
従来のチェンは、リンク本体が水面上に来た時に上向きになる窪み部を有するため、汚泥掻き寄せ機を稼働させてない時は、その窪み部に水が溜まったまま空気中にさらされることとなっていた。
そして、その窪み部に溜まった水が汚泥掻き寄せ機が稼働しない期間の間に蒸発し、窪み部に溜まった水が有していた酸性物質が濃縮され強酸化し、樹脂製であるリンク本体を侵食し破断することが多々あった。
Conventional chains have a dent that faces upward when the link body is on the surface of the water, so when the sludge scraper is not operating, the dent is exposed to the air with water remaining in the dent. It was.
Then, the water accumulated in the depression evaporates during a period when the sludge scraper does not operate, the acidic substance contained in the depression accumulated in the depression is concentrated and strongly oxidized, and the link body made of resin is It often eroded and broke.
そこで、本発明は、上記の問題点に鑑みて、リンク本体の窪み部に水が溜まることを防止し、酸性物質によるリンク本体の侵食、破断を防止することを課題とするものである。 In view of the above problems, an object of the present invention is to prevent water from accumulating in the depression of the link body, and to prevent erosion and breakage of the link body due to an acidic substance.
本発明は上記課題を解決するためになされたものであり、樹脂製で一体成形されるリンク本体を連ねて構成されるチェンにおいて、前記リンク本体の窪み部に蓋部材を取り付けたことを特徴とするものである。 The present invention has been made in order to solve the above-described problems, and is characterized in that, in a chain configured by connecting a link body integrally formed of resin, a lid member is attached to a recess portion of the link body. To do.
このような本発明によれば、樹脂製で一体成形されるリンク本体を連ねて構成されるチェンにおいて、前記リンク本体の窪み部に蓋部材を取り付けることにより、リンク本体の窪み部に水が溜まることを防止し、酸性物質によるリンク本体の侵食、破断を防止することができる。 According to the present invention as described above, in the chain configured by connecting the link main body integrally formed of resin, water is accumulated in the hollow portion of the link main body by attaching the lid member to the hollow portion of the link main body. This can prevent erosion and breakage of the link body due to the acidic substance.
以下、本発明を実施するための最良の形態について、図面に基づいて具体的に説明する。チェン本体の形状のうち、従来のチェン本体とほとんど変わらない部分は説明を省略する。 Hereinafter, the best mode for carrying out the present invention will be specifically described with reference to the drawings. Of the shape of the main body of the chain, description of parts that are almost the same as the conventional main body of the chain is omitted.
図１は、本発明の実施の形態に係るリンク本体１０の全体図である。 FIG. 1 is an overall view of a link body 10 according to an embodiment of the present invention.
本発明の実施の形態に係るリンク本体１０では、窪み部２４を覆うように蓋部材２６が取り付けられる。 In the link main body 10 according to the embodiment of the present invention, the lid member 26 is attached so as to cover the recess 24.
蓋部材２６が取り付けられることによりリンク本体１０の窪み部２４に酸性物質を含んだ水が窪み部２４に入り込まないので、リンク本体１０の窪み部２４に水が溜まることを防止し、酸性物質によるリンク本体１０の侵食、破断を防止することができる。 Since the lid member 26 is attached, water containing an acidic substance does not enter the dent part 24 in the dent part 24 of the link body 10, thereby preventing water from accumulating in the dent part 24 of the link body 10, and The link body 10 can be prevented from being eroded and broken.
本実施の形態では、一体の蓋部材を取り付ける例を説明したが、蓋部材を、窪み部ごとにわけて取り付けてもかまわないのは言うまでもない。
In the present embodiment, an example in which an integral lid member is attached has been described, but it goes without saying that the lid member may be attached separately for each recess.
