て吸引するパイプ式スカムスキマ−の軸受に関するもの
である。[Detailed Description of the Invention] The present invention relates to a bearing for a pipe-type scum skimmer that sucks up scum floating on the water surface of a sedimentation tank in a sedimentation tank in a sewage treatment plant or the like by making the opening follow the water surface.
従来、パイプ式スカムスキマ−軸受の形式は種々存在す
るが、その１例を示せば第１図の通りである。Conventionally, there are various types of pipe type scum skimmer bearings, one example of which is shown in FIG.
第１図において、ａは軸受本体で、ｂはパイプスキマー

嵌入されている。In other words, the short pipe has both end flanges extending to both sides of the side wall, and a drain plate in the middle part is embedded in the same side wall, and passes through the side wall.
A bearing body is attached which has a flange at the end that connects with the flange on the inner side of the sedimentation tank of the short pipe, and the bearing body has a bearing metal on the inner circumference side and the bearing metal on both sides through the bearing metal. An oil seal is attached to seal the oil seal, and a pipe skimmer is fitted into the inner circumferential side of the oil seal, and a pipe skimmer is fitted with a sleeve that is in sliding contact with the bearing metal and the oil seal.
このように部品点数が多く精密な加工をするために据付
が困難になり、又回転しにくくなる欠点がある。Since the number of parts is large and precision machining is required, installation is difficult and rotation is difficult.
又壁貫通の短管ｆを別途製作取付けるという無駄が生じ
ていた。In addition, there was a waste of separately manufacturing and installing a short pipe f that penetrates the wall.

部品点数を大幅に消滅したパイプ式スカムスキマ−用軸
受を提供するものである。In the present invention, a pair of short end pipes attached to a pipe-type scum skimmer with an opening for sucking scum floating on the water surface of the sedimentation tank are fitted into the concrete wall of the sedimentation tank, and the central part of the pipe is fitted into the concrete wall of the sedimentation tank. It is characterized by being pivotally supported by a pair of short pipes made of spheroidal graphite cast iron with flanges joined together, and its purpose is to eliminate the above-mentioned conventional drawbacks and to reduce the frequency of use and rotation of pipe-type scum skimmers. The present invention provides a bearing for a pipe type scum skimmer that has a greatly reduced number of parts in consideration of speed.
以下、本考案の好ましい実施例を第２図および第３図に
図示する実施例に基づいて説明する。Hereinafter, preferred embodiments of the present invention will be described based on the embodiments shown in FIGS. 2 and 3.
第２図で１は一方が拡開しその両端部にフランジを有し
、拡開部に取付けられたフランジ同志を接合し、沈殿池
のコンクリート壁に嵌め込まれた一対の球状黒鉛鋳鉄製
短管である軸受本体。In Figure 2, 1 is a pair of spheroidal graphite cast iron short pipes with one side expanded and flanges at both ends, the flanges attached to the expanded part joined together, and fitted into the concrete wall of the sedimentation basin. The bearing body.
２はスカムスキマ一本体パイプ３（通常ＳＧＰ製）とフ
ランジ接続しているＳＵＳ製端部短管で軸受本体１との
接触面で回転する。Reference numeral 2 denotes a short pipe at the end made of SUS which is flange-connected to the scum skimmer main body pipe 3 (usually made by SGP) and rotates on the contact surface with the bearing main body 1.
４は端部短管２にボルトでセットされたカラーでスキマ
一本体の横移動を防ぐと共に第３図に示すＯリング５を
固定している。Reference numeral 4 is a collar set on the end short tube 2 with a bolt to prevent the lateral movement of the gap body and also to fix an O-ring 5 shown in FIG. 3.
このような実施例ではスカムを抜くためにスキマ一本体
端部短管かハンドル等で回転せられると、端部短管２と
軸受６との間でスムーズに回転する。In such an embodiment, when the short tube at the end of the gapper body is rotated by a handle or the like to remove scum, the short tube at the end of the main body 2 rotates smoothly between the short tube at the end and the bearing 6.
カラー４にスキマ一本体の横移動を防止し同時にＯリン
グ５を固定している。A gap in the collar 4 prevents the main body from moving laterally, and at the same time fixes the O-ring 5.
Ｏリング５は取水口以外からの水の浸入を防いでいる。The O-ring 5 prevents water from entering from sources other than the water intake.
以上の実施例において説明したように、本考案は次のよ
うな効果が得られる。As explained in the above embodiments, the present invention provides the following effects.
（１）耐摩耗性の大きい球状黒鉛鋳鉄製短管を使用する
ことにより軸受メタルが不要となった。(1) By using short tubes made of spheroidal graphite cast iron with high wear resistance, bearing metal is no longer required.
また製作容易で工数が消滅された。In addition, it is easy to manufacture and man-hours are eliminated.
（２）側壁に埋没貫通することにより別途製作していた
短管が省略された。(2) By penetrating the side wall, the separately manufactured short pipe was omitted.
（３） 鋳鉄異形管の一方のフランジが自然に貫通管
の水切板を構成しているので特別に水切板を製作する必
要がない。(3) Since one flange of the cast iron deformed pipe naturally forms the drainage plate of the through pipe, there is no need to manufacture a special drainage plate.
（４）性能を低下することなく軸受メタル・オイルシー
ル・給油系路をなくすことにより部品を大巾になくし、
大幅なコストダウンとなる。(4) By eliminating the bearing metal, oil seal, and oil supply line without degrading performance, we can eliminate a large number of parts.
This results in a significant cost reduction.
