Description
【０００１】
【産業上の利用分野】
本発明は、圧縮途中に潤滑油を噴射する油冷式圧縮機の油分離エレメントに関する。
【０００２】
【従来の技術】
従来では、特開昭５７−１２７８８３号公報のように、油分離エレメントは平らな形状であり垂直方向の取付け姿勢ではこの平らな面にドレンが残留し、その状態で長時間使用されている。
【０００３】
【発明が解決しようとする課題】
従来技術は、圧縮空気中の油を分離したあとに圧縮空気中の水分が凝縮しこれがドレンとして油分離エレメントの平らな面に付着する。この付着量は圧縮機の負荷変動や運転時間により徐々に蓄積され、所々にコロニー上に点在していく。この状態が長時間続くと油分離エレメントを構成する鉄板を腐食させて錆が発生し、ついには、これに孔があいてしまう。この腐食を防止するため鉄板表面にはメッキ処理をしているが万全ではなく孔があく例がある。孔があくと、この部分から油を分離されない圧縮空気が流れてきて油分離の機能が損なわれる。
【０００４】
【課題を解決するための手段】
上記目的を達成するため、本発明は、空気圧縮機、圧縮空気中の油分を分離する油タンク、及び前記油タンクの下部に溜まった油を冷却するための熱交換器を備えた油冷式圧縮機において、前記油タンクは、圧縮途中で混入した潤滑油を分離する油分離エレメントを内蔵し、この油分離エレメントは、内筒と外筒の間に設けられた油分離用の分離フィルタ、上部蓋板、下部蓋板、油分離エレメント内底部に設けられた油溜りを備え、前記油分離エレメントの上部蓋板は、該上部蓋板に付着したドレン（凝縮水）が油分離エレメント内下部の前記油溜りに流出するように内側に傾斜した構造とされ、更に、前記油溜りに溜まったドレンを圧縮機の吸入側に回収する回収パイプを備えていることを特徴とするものである。
【０００５】
【作用】
油分離エレメントの上部の蓋板が、一定の角度で内側に傾斜しているため、この面に付着したドレンは傾斜のためにその位置に留まることが出来ずに流れて、分離エレメントを構成する底板に設けてある分離した油の油溜り部に落ちてくる。ここへ溜ったドレンは分離した油と共に圧縮機の吸入側、あるいは、給油配管中に回収される。
【０００６】
【実施例】
本発明の実施例を図１，図２を用いて説明する。
【０００７】
図２は本発明の給油式スクリュー圧縮機のフローを模式的に表現したものである。圧縮機１１で圧縮された空気は、冷却やシールとして圧縮途中に噴射された油と共に入口配管を通って油タンク１２に入ってくる。ここで一次分離された油１５は、油タンクの下部に溜り、残りは、油分離エレメント１４で空気と分離され、圧縮空気として油タンクから出ていく。油分離エレメントで分離された油は図１のようにエレメントの底部の油溜り６に溜り、ここに設けられた回収パイプ１６で圧縮機側へ回収される。
【０００８】
圧縮された空気中には水分が含まれ温度が下がると過飽和状態となり過飽和分は凝縮してドレンとなって分離エレメントの表面に付着したり、圧縮空気と共に持ち去られたりする。
【０００９】
分離エレメントの表面に付着したドレン７は分離エレメントの上部蓋板１の表面に着くが、この形状が内側へ傾斜しているため流れ落ちて、エレメント底部の油溜り６に入る。すると、ここへ接続されている回収パイプ１６により、油と共に回収されていく。
【００１０】
【発明の効果】
本発明によれば、油タンク内に内臓された油分離エレメントは、内筒と外筒の間に設けられた油分離用の分離フィルタ、上部蓋板、下部蓋板、油分離エレメント内底部に設けられた油溜りを備え、上部蓋板は、該上部蓋板に付着したドレンが油分離エレメント内下部の油溜りに流出するように内側に傾斜した構造とされ、かつ油溜りに溜まったドレンを圧縮機の吸入側に回収する回収パイプを備えているので、油分離エレメント内で発生したドレンはエレメントの上部蓋板の表面にいつまでも付着し続けることを防止でき、エレメント底部の油溜りに速やかに流れ落ちて、ここから圧縮機吸入側に回収することができる。従って、油分離エレメントの上部蓋板にドレンが残留することによる錆の発生を抑制することができ、孔あきなどによる機能低下を防止できる効果がある。

[Industrial applications]
The present invention relates to an oil separation element of an oil-cooled compressor that injects lubricating oil during compression.
[0002]
[Prior art]
Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 57-127883, the oil separation element has a flat shape, and the drain remains on the flat surface in a vertical mounting posture, and the oil separation element is used for a long time in that state.
[0003]
[Problems to be solved by the invention]
In the prior art, after the oil in the compressed air is separated, the water in the compressed air condenses and adheres as a drain to the flat surface of the oil separation element. This adhesion amount is gradually accumulated due to the load fluctuation and the operation time of the compressor, and is scattered in some places on the colony. If this state continues for a long time, the iron plate constituting the oil separation element is corroded and rust is generated, and eventually, a hole is formed in the rust. In order to prevent this corrosion, the surface of the iron plate is plated. If a hole is formed, compressed air from which oil cannot be separated flows from this portion, and the function of oil separation is impaired.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an oil-cooled type including an air compressor, an oil tank for separating oil in compressed air, and a heat exchanger for cooling oil accumulated in a lower portion of the oil tank. In the compressor, the oil tank has a built-in oil separation element for separating lubricating oil mixed during compression, and the oil separation element is provided with a separation filter for oil separation provided between an inner cylinder and an outer cylinder. An oil reservoir is provided at an upper lid plate, a lower lid plate, and an oil reservoir provided at a bottom portion inside the oil separation element. And a collecting pipe for collecting the drain collected in the oil sump on the suction side of the compressor.
[0005]
[Action]
Since the upper cover plate of the oil separation element is inclined inward at a certain angle, the drain attached to this surface flows without being able to stay at that position due to the inclination and constitutes the separation element. It falls into the separated oil sump provided on the bottom plate. The drain collected here is collected together with the separated oil on the suction side of the compressor or in the oil supply pipe.
[0006]
【Example】
An embodiment of the present invention will be described with reference to FIGS.
[0007]
FIG. 2 is a schematic representation of the flow of a refueling screw compressor according to the present invention. The air compressed by the compressor 11 enters the
[0008]
The compressed air contains moisture, and when the temperature decreases, the air becomes supersaturated, and the supersaturated portion condenses to form a drain, adheres to the surface of the separation element, or is carried away with the compressed air.
[0009]
The drain 7 adhering to the surface of the separation element arrives at the surface of the
[0010]
【The invention's effect】
According to the present invention, the oil separation element contained in the oil tank is provided with a separation filter for oil separation provided between the inner cylinder and the outer cylinder, an upper lid plate, a lower lid plate, and a bottom portion inside the oil separation element. An oil reservoir is provided, and the upper lid plate has a structure in which the drain attached to the upper lid plate is inclined inward so as to flow out to a lower oil reservoir inside the oil separation element, and the drain collected in the oil reservoir. Is provided on the suction side of the compressor, so that the drain generated in the oil separation element can be prevented from continuing to adhere to the surface of the upper lid plate of the element forever, and quickly drained into the oil pool at the bottom of the element. And can be recovered from here to the compressor suction side. Therefore, the generation of rust due to the drain remaining on the upper lid plate of the oil separation element can be suppressed, and there is an effect that the functional deterioration due to perforation or the like can be prevented.
