Description

本発明は、工場等の作業場で用いられている各種作業機器周りで発生するオイルミストや油煙、あるいは溶接ブースで発生する溶接ヒュームや粉塵など、気体や蒸気中に何等かの微細混合物(以下、塵埃と総称する)を含んで全体としては気相を呈する流体や、気体とともに吸引される洗浄水や油などの液体を含む流体(以下、本明細書中では何れも「気相流体」と呼称する。)を処理対象として、その気相流体中から塵埃などの被除去物を除去するための除塵装置に関する。   The present invention is an oil mist and oil smoke generated around various work equipment used in a workplace such as a factory, or any fine mixture in a gas or steam such as welding fumes and dust generated in a welding booth (hereinafter, Fluid that exhibits a gas phase as a whole, including dust, and fluid that includes a liquid such as cleaning water or oil that is sucked together with gas (hereinafter referred to as “gas phase fluid” in this specification) The present invention relates to a dust removal apparatus for removing a removal object such as dust from the gas phase fluid.

この種の気相流体を処理する除塵装置としては、ケーシング内に気相流体の処理経路を形成し、その処理経路に、気相流体と衝突するバフラーや、気相流体と接触して気相流体中に含まれるオイルミストや溶接ヒュームなどを捕捉する布様濾材からなるフィルターを備えたものが、下記の特許文献1に示されるように従来より知られている(特許文献1参照)。
また、このような除塵装置においては、除塵装置の吸気口に外部から処理対象の気相流体を導入するためのダクトを吸気口に対して接続するにあたり、吸気口にシール材を介して外嵌したダクトの先端部を、外側から金属製のホースバンドを用いて締め付けることにより接続することが一般的に行われている。そのようなホース等の締め付けのために用いられるホースバンドとしては、例えば下記の特許文献2に示すような構造のものが知られている。
As a dust removing device for processing this kind of gas-phase fluid, a gas-phase fluid processing path is formed in the casing, and a baffle that collides with the gas-phase fluid or a gas-phase fluid in contact with the gas-phase fluid in the processing path. BACKGROUND ART A filter provided with a cloth-like filter medium that captures oil mist, welding fume, and the like contained in a fluid is conventionally known as shown in Patent Document 1 below (see Patent Document 1).
Further, in such a dust removal device, when connecting a duct for introducing a gas phase fluid to be processed from the outside to the intake port of the dust removal device to the intake port, it is fitted to the intake port via a sealing material. In general, the end of the duct is connected by tightening it from the outside using a metal hose band. As a hose band used for fastening such a hose or the like, for example, a structure as shown in Patent Document 2 below is known.

登録実用新案第3006924号公報(段落「0010」、「0015」、「図1」、「図4」、「図5」)Registered Utility Model No. 3006924 (paragraphs “0010”, “0015”, “FIG. 1”, “FIG. 4”, “FIG. 5”) 特開2005−30528号公報(段落「0072」、「図3」、「図5」、「図6」、「図7」、「図8」)JP-A-2005-30528 (paragraphs “0072”, “FIG. 3”, “FIG. 5”, “FIG. 6”, “FIG. 7”, “FIG. 8”)

この種の除塵装置に処理対象の気相流体を導くにあたって、一般的には可撓性のダクトを用い、そのダクトの一端部を除塵装置の吸気口に外嵌させて接続している。吸気口にダクトを外嵌させるのは、ダクト内周面と吸気口外周面との間に、気相流体の漏れ出しを防止するようにシール材を介装するためであり、吸気口に外嵌させたダクトの外側から、特許文献2に記載のホースバンド等を用いて締め付けることにより密封作用を発揮させるようにしている。
このような接続構造を用いることにより、接続当初の一時期は、ある程度期待される気密、液密構造が保たれているが、次第にシール材やダクトそのものが劣化してくるに伴い、どうしても油分などの液状化物質の漏れ出しが生じてしまうという問題がある。この油分の漏れ出しは、量としてはごく僅かずつであっても、長期間のうちに、漏れ出た油分が広範囲に拡がって固化し酸化することにより非常に汚れが目立つ状態となり易い。
また、特許文献1に記載の除塵装置では、気相流体がバフラーと衝突したり、ラビリンス状の流路を流れる際の布様濾材との接触によって、気相流体中の塵埃が捕集除去されるものであるが、気相流体中に多くの塵埃や油分が含まれる場合などには、早期のうちに濾材の目詰まりが生じて濾材の交換に多くの手数を要するというメンテナンスの煩雑化を招き易いという問題がある。
In order to guide the gas phase fluid to be processed to this kind of dust removing device, a flexible duct is generally used, and one end of the duct is externally fitted to the intake port of the dust removing device. The reason why the duct is externally fitted to the intake port is that a sealing material is interposed between the inner peripheral surface of the duct and the outer peripheral surface of the intake port to prevent leakage of gas phase fluid. From the outside of the fitted duct, the hose band described in Patent Document 2 is used for tightening to exert a sealing action.
By using such a connection structure, the airtight and liquid-tight structure expected to some extent is maintained for a period of time at the beginning of the connection. There is a problem that leakage of the liquefied material occurs. Even if the amount of the oil leaked out is very small, the leaked oil spreads over a wide range and solidifies and oxidizes over a long period of time, so that the dirt is very conspicuous.
Moreover, in the dust removal apparatus described in Patent Document 1, dust in the gas phase fluid is collected and removed by contact with the cloth-like filter medium when the gas phase fluid collides with the baffle or flows through the labyrinth flow path. However, when a large amount of dust or oil is contained in the gas phase fluid, the filter medium is clogged in an early stage, which requires a lot of trouble to replace the filter medium. There is a problem that it is easy to invite.

本発明の目的は、気相流体の処理に際して、接続箇所や開閉箇所から漏れ出した油分等の液状化物質による汚れを、比較的小型で簡単な構造で目立たないようにすることにあり、さらに他の目的としては、除塵装置で用いられるフィルターが処理対象の気相流体中の塵埃や油分による影響で早期に劣化することを極力抑制できるようにすることにある。   It is an object of the present invention to prevent contamination by liquefied substances such as oil leaking from connection points and open / close points during processing of a gas phase fluid with a relatively small and simple structure, and further, Another object of the present invention is to make it possible to suppress as much as possible the deterioration of the filter used in the dust removal device due to the influence of dust and oil in the gas phase fluid to be processed.

上記目的を達成するために講じた本発明の技術手段は、次の点に構成上の特徴がある。   The technical means of the present invention taken in order to achieve the above object has the following structural features.

This is to provide a liquid passage hole for connecting the liquid receiving portion and the casing internal space.

〔作用〕
上記の技術手段を講じたことによる作用は次の通りである。
すなわち、前記ダクトとの接続箇所や、前記ケーシング内部における処理経路の吸気側空間を構成するケーシング壁に形成された開口とその開口を閉塞する蓋体との開閉箇所からの油分の漏れ出しを阻止するのではなく、漏れ出た油分などの液状化物質を下側の液受け部で受け、その後、通液孔を介して再び処理経路内に戻すものであるから、前記続箇所や開閉箇所から漏れ出た油分などの液状化物質が液受け部外にまで拡がることを回避できる。
また、前記通液孔は、処理経路の吸気側と連通されているので、処理経路の排気側と連通した場合のように、処理経路内の流体が通液孔から液受け部側へ向けて逆流するような流れを生じることはなく、液受け部から通液孔への流体の移動を妨げることがない。
[Action]
The effects of taking the above technical means are as follows.
That is, oil leakage is prevented from being connected to the duct or from an opening / closing position of an opening formed in a casing wall that constitutes an intake side space of a processing path inside the casing and a lid that closes the opening. Instead of receiving the liquefied substance such as leaked oil in the lower liquid receiving portion, and then returning it to the processing path again through the liquid passage hole, It is possible to prevent the liquefied substance such as leaked oil from spreading to the outside of the liquid receiving portion.
Further, since the liquid passage hole communicates with the intake side of the processing path, the fluid in the processing path is directed from the liquid passage hole toward the liquid receiving portion as in the case where the fluid passage hole communicates with the exhaust side of the processing path. A reverse flow is not generated, and movement of the fluid from the liquid receiving portion to the liquid passage hole is not hindered.

〔解決手段2〕

[Solution 2]
The dust removing device of the present invention is the dust receiving device according to claim 1, wherein the dust receiving device receives the liquefied substance in the gas phase fluid leaking outside from the connection location or the open / close location. In addition, a blindfolding means for visually shielding the lower portion of the connection location or the opening / closing location from the outside may be provided.

〔作用〕

すなわち、吸気口とその吸気口に被処理流体を案内導入するダクトとの接続箇所の下側、またはケーシング壁に形成された開口とその開口を閉塞する蓋体との開閉箇所の下側に油分が漏れ出しても、その漏れ出た部分が液受け部の目隠し手段によって外部から遮蔽された状態となり、漏れ出た油分の付着した部位の汚れを外部から視認し難くすることができる。
[Action]
The effects of taking the above technical means are as follows.
That is, the oil content is below the connection point between the intake port and the duct that guides and introduces the fluid to be processed into the intake port, or below the opening / closing point between the opening formed in the casing wall and the lid that closes the opening. Even if the oil leaks out, the leaked portion is shielded from the outside by the blindfolding means of the liquid receiving portion, and it is possible to make it difficult to visually recognize the dirt on the leaked portion to which the oil has adhered.

[Solution 3]
As described in claim 3, the dust removing device of the present invention is the dust removing device according to claim 1 or 2, wherein the air introduced from the intake port is located on the upper side of the processing path with respect to the portion where the wind generating means is provided. A swirling dust removal unit that swirls and flows the phase fluid in the casing is provided.
This swirling dust removing section is arranged so that an annular swirling flow path is formed between the inner wind guide cylinder in which the direction of the cylinder axis is set along the horizontal direction and the wind guide cylinder. An outer cylinder arranged at the outer side, means for generating a swirling flow in the swirling flow path by directing the gas-phase fluid introduced from the intake port in a tangential direction of the air guiding cylinder, and on the outermost side of the swirling flow It consists of a dust separator that allows the contained objects to jump out of the swirling flow and escape from the swirling flow,
The dust separation portion is disposed on the lower side of the outer cylinder, and a liquid receiving portion of a liquid receiving portion provided below an opening / closing portion of an opening formed in the casing wall and a lid closing the opening, Connected to the dust separator,
The dust separation unit may be provided with an external take-out path for discharging the liquid that has been taken into the outer cylinder from the liquid receiving part and naturally flows down to the outside of the processing path.

〔作用〕
上記の技術手段を講じたことによる作用は次の通りである。
すなわち、処理経路内に旋回除塵部を備え、かつ、その旋回除塵部の旋回流から外方へ飛びした塵埃を受ける塵埃分離部に、液受け部から取り込まれて自然流下した液体を処理経路外へ排出させるための外部取り出し路を設けてあるので、液受け部から一旦ケーシングを構成する外囲筒体の内部に取り込んだ油分や、気相流体中に含まれる多量の塵埃を、外部取り出し路で自重により自然流下させることによって極力外部へ排出し、処理経路下手側に位置するフィルター側への油分や塵埃の移行を極力制限することができる。
[Action]
The effects of taking the above technical means are as follows.
In other words, a swirling dust removing section is provided in the processing path, and the liquid that has been naturally flowed down from the liquid receiving section is collected outside the processing path by the dust separating section that receives the dust that flies outward from the swirling flow of the swirling dust removing section. Since an external take-out path is provided for discharging the oil into the outer cylinder once constituting the casing from the liquid receiving part, a large amount of dust contained in the gas phase fluid is removed from the external take-out path. Thus, by letting it flow down naturally by its own weight, it can be discharged to the outside as much as possible, and the transfer of oil and dust to the filter side located on the lower side of the processing path can be limited as much as possible.

請求項1にかかる発明によれば、ダクトと吸気口の接続箇所や、ケーシング壁に形成された開口とその開口を閉塞する蓋体との開閉箇所から漏れ出た油分などの液状化物質を下側の液受け部で受け、その後、通液孔を介して再び処理経路内に戻すものであるから、前記続箇所や開閉箇所から漏れ出た油分が広範囲に拡がることを、比較的コンパクトな液受け部の存在によって回避して、汚れを目立ち難くすることができる。また、通液孔を処理経路の吸気側と連通させて液受け部からケーシング内への流体の移動がスムースに行われるようにしている。
その結果、前記接続箇所や開閉箇所でのシール構造としては特別高機能のものを採用する必要がないものでありながら、漏れ出た油分などの液状化物質による汚れを目立ち難くする構成を、小型で簡単な構造で得ることができる利点がある。
According to the first aspect of the present invention, the liquefied substance such as oil leaking from the connection portion between the duct and the air inlet, the opening / closing portion between the opening formed in the casing wall and the lid for closing the opening is disposed. Since the oil is leaked from the connecting part and the opening / closing part, the oil is leaked over a wide range. By avoiding the presence of the receiving portion, it is possible to make the dirt less noticeable. Further, the fluid passage hole is communicated with the intake side of the processing path so that the fluid is smoothly moved from the liquid receiving portion into the casing.
As a result, it is not necessary to adopt a special high-performance seal structure at the connection point or opening / closing point, but the structure that makes dirt due to liquefied substances such as leaked oil less noticeable is compact. There is an advantage that can be obtained with a simple structure.

請求項2にかかる発明によれば、長期間の使用によって油分などの液状化物質が漏れ出すことがあっても、その漏れ出た部分が液受け部の目隠し手段によって外部から遮蔽された状態となり、漏れ出た油分の付着した部位の汚れを外部から視認し難くすることができる利点がある。
また、その目隠し手段も液受け部の一部を利用して構造の簡素化を図り得るとともに、小型な液受け部箇所を利用することで、目隠し手段自体も小型化できる利点がある。
According to the second aspect of the present invention, even if a liquefied substance such as oil leaks due to long-term use, the leaked part is shielded from the outside by the blindfolding means of the liquid receiving part. There is an advantage that it is possible to make it difficult to visually recognize the dirt on the part where the leaked oil adheres.
Further, the blindfolding means can be simplified in structure by using a part of the liquid receiving portion, and there is an advantage that the blindfolding means itself can be reduced in size by using a small liquid receiving portion.

請求項3にかかる発明によれば、液受け部から一旦ケーシング内に取り込んだ油分や、気相流体中に含まれる多量の塵埃を、外部取り出し路で自重流下させることによって、極力外部へ排出し、処理経路下手側に位置するフィルター側への油分や塵埃の移行を極力制限することができ、これによって、処理経路内に設けられるフィルター部位への油分や塵埃の移行量を大きく減少させて、フィルターの良好な稼働可能時間を延長できる利点がある。   According to the invention of claim 3, the oil once taken into the casing from the liquid receiving part and the large amount of dust contained in the gas phase fluid are discharged to the outside as much as possible by allowing the external take-off flow to flow down by their own weight. The transfer of oil and dust to the filter side located on the lower side of the processing path can be limited as much as possible, thereby greatly reducing the transfer amount of oil and dust to the filter site provided in the processing path, There is an advantage that the good operation time of the filter can be extended.
