Abstract

<P>PROBLEM TO BE SOLVED: To provide a supply opening unit suppressing accumulation of powder dust as a contaminant source, usage of materials which are limited resources, and energy in processing, in a housing for loading an ultrahigh performance filter used in a clean room and the like. <P>SOLUTION: A mounting hardware (1) for fixing the filter is externally mounted outside of the housing, and a space (9) between the filter (8) and an inside dimension of the housing is minimized to minimize the accumulation of contaminated airflow. As a seal section of the filter and the housing is composed of a bracket metal (2) of a structure not by face contact but by line contact, the pressing force to the filter and each member of the housing can be minimized, and the load to each part of the housing can be minimized. As the components is assembled without having welding sections, environmental load is reduced. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、クリーンルーム等に使用される超高性能フィルタを装填するための筐体で、汚染源である粉塵滞留と、限りある資源である材料使用量・加工上のエネルギーを抑制したフィルタ吹出口ユニットに関するものである。  The present invention is a housing for loading an ultra-high performance filter used in a clean room or the like, and a filter outlet unit that suppresses dust accumulation as a contamination source and material usage and processing energy as limited resources. It is about.

従来、超高性能フィルタ等を内装する吹出口ユニットは、フィルタ外形寸法に対し一回り大きい筐体とし内部には、フィルタ固定用の金具類を溶接にて取り付けていた。
しかし、この方法では、フィルタと筐体との無駄な空間に汚染源である粉塵等が滞留しやすく、また筐体使用材料が多く必要となり、溶接加工時等のヒュームによる作業環境は勿論のこと電気エネルギーの消費量も看過できないなどの問題があった。
さらに、強度を保つために筐体板厚も厚くする必要があるために重量がかさみ施工性も悪いなどの問題があった。
Conventionally, an air outlet unit incorporating an ultra-high performance filter or the like has a casing that is one size larger than the outer dimensions of the filter, and metal fittings for fixing the filter are attached inside by welding.
However, with this method, dust that is a source of contamination tends to stay in the wasted space between the filter and the housing, and a lot of material is required for the housing. There was a problem that energy consumption could not be overlooked.
Furthermore, since it is necessary to increase the thickness of the housing plate in order to maintain the strength, there is a problem that the weight is bulky and the workability is poor.

従来は、次のような問題点があった。
筐体内部には、フィルタを固定するための取付け金具があるためにフィルタより一回り大きい筐体とせざるを得なかった。この空間があることで汚染塵埃が滞留しやすくなり速やかな浄化機能を損なうこと、金具の取付けに伴い発生する加工時の溶接ヒュームによる作業環境汚染,溶接後の洗浄、修正加工作業等々、使用材料は勿論のこと加工上の消費エネルギーも看過できない状況にあった。
また、フィルタと筐体とのシール部は、面接触により塵埃のリークを防止する構造となっているが面接触のためにフィルタに付属するパッキン材料を均等に押圧する必要があり、この押圧力は、フィルタサイズにより異なるが数百キログラム以上の負荷を構造体各部に与える結果となり、各部材に相応の強度を必要とするなど使用材料も多くの材料を使用することとなっていた。したがい、質量も相当量となり施工性の問題も看過できない状況にあった。
本発明は、上記欠点を解決しようとするものである。
Conventionally, there are the following problems.
Since there is a mounting bracket for fixing the filter inside the casing, the casing must be one size larger than the filter. This space makes it easy to collect contaminated dust and impairs the rapid purification function. Working materials are contaminated by welding fumes generated during the installation of metal fittings, cleaning after welding, corrective work, etc. Needless to say, the energy consumption during processing cannot be overlooked.
In addition, the seal part between the filter and the housing is structured to prevent dust leakage by surface contact, but it is necessary to evenly press the packing material attached to the filter for surface contact. However, the load of several hundred kilograms or more is applied to each part of the structure, depending on the filter size, and a large amount of materials are used because each member requires appropriate strength. Therefore, the mass was considerable, and the problem of workability could not be overlooked.
The present invention seeks to solve the above disadvantages.

上記欠点を解消するため本発明は、図1・図2に示すようにフィルタ固定用の取付け金具(1)を筐体外に外装しフィルタ(8)と筐体内寸法との空間を最小限にすることで汚染気流の滞留を最小にすることを可能とした。
また、フィルタと筐体とのシール部は、面接触でなく線接触となるような構造の受け金具(2)とした。この構造とすることでフィルタ並びに筐体各部材への押圧力を最小限に抑えることが可能となり筐体・各部への荷重を最小限にすることを可能とした。
各部への負荷を最低限にすることで使用材料の軽量化による施工性の向上も図ることができる。筐体(3)(4)は、外周の折返し端面部(5)をあらかじめネジ加工された固定用ビス(6)等で接続され端面部(5)形状を保持すると共に吹出面であるパンチング等の多孔板(7)を固定するための受けネジを兼ねる。
また、外周の折返し部には、フィルタを筐体内部にあるフィルタ受け金具(2)に押圧するためのフィルタ取付け金具(1)を有する。
各部品の組立には、溶接部を皆無とすることで溶接ヒュームによる環境負荷の低減も可能としたフィルタ吹出口ユニットである。
In order to eliminate the above-mentioned drawbacks, the present invention, as shown in FIGS. 1 and 2, externally mounts a mounting bracket (1) for fixing the filter outside the casing to minimize the space between the filter (8) and the dimensions within the casing. This makes it possible to minimize the residence of contaminated airflow.
Further, the seal part between the filter and the housing is a receiving metal fitting (2) having a structure that is not a surface contact but a line contact. With this structure, it is possible to minimize the pressing force on the filter and each member of the casing, and it is possible to minimize the load on the casing and each part.
By minimizing the load on each part, the workability can be improved by reducing the weight of the material used. The casings (3) and (4) are connected to the outer peripheral folded end surface portion (5) with a screw (6) or the like that is pre-threaded to hold the shape of the end surface portion (5) and punching that is a blowout surface. It also serves as a receiving screw for fixing the perforated plate (7).
Further, the folded portion on the outer periphery has a filter mounting bracket (1) for pressing the filter against the filter bracket (2) inside the housing.
The assembly of each part is a filter outlet unit that can reduce the environmental load due to welding fume by eliminating the welds.

以下本発明の実施形態を図面について説明する。
高清浄度空間を必要とするクリーンルームで使用される超高性能フィルタを内装する吹出口では、施工性・メンテナンス性・製造上の環境負荷低減を考慮することは、勿論のこと、その筐体内部に汚染気流を滞留させることの無いよう設計されなければならない。
図2は、本発明の全体斜視図、図1は、その詳細断面図である。
図1にあるようにフィルタ装填部には、フィルタ受け金具(2)を除き、汚染気流の滞留を防止するため、一切の金具を排除した。
その結果、筐体とフィルタとの汚染気流の滞留部を最小とすることが可能となった。クリーンルームでは、稼動前に吹出口ユニットからの汚染塵埃等が漏洩していないことを確認するためのリーク試験があるが滞留部が大きいとリーク試験中に長時間にわたり滞留部に溜まっている塵埃とフィルタのリークとの相違がわかり難いために、その原因調査に膨大な時間を必要とする。
フィルタの取付け金具(1)を筐体外に外装することで筐体(3)、筐体(4)とフィルタ(8)の間隙を最小とすることが出来、この問題を解消することができる。
筐体は、薄板構造のため、この取付け金具(1)は、筐体の立ち上がり部近傍に設置することでフィルタ締結時に掛かる荷重負荷に対する強度を高めているのでフィルタ(8)は、確実に固定することが可能である。
また、フィルタ受け金具(2)は、フィルタ(8)に付属するパッキンを線接触にて押圧するため少ない締結力により確実に空気漏洩を防止することが可能であり、かつ筐体各部への負荷を少なくすることが可能なため筐体を薄板にて製作可能とすることで軽量化、施工性の向上を可能とした。
筐体の折り返し端面部(5)には、平面・台形等の各種形状を有するパンチングを取付けることも可能である。
Embodiments of the present invention will be described below with reference to the drawings.
In the air outlet with an ultra-high performance filter that is used in a clean room that requires a high cleanliness space, it is a matter of course to consider workability, maintainability, and reduction of environmental impact in manufacturing. It must be designed so that no contaminated airflow is retained.
FIG. 2 is an overall perspective view of the present invention, and FIG. 1 is a detailed sectional view thereof.
As shown in FIG. 1, the filter loading part except for the filter holder (2) was used to eliminate any metal fittings to prevent stagnation of contaminated airflow.
As a result, it is possible to minimize the staying part of the contaminated airflow between the housing and the filter. In a clean room, there is a leak test to confirm that the contaminated dust from the air outlet unit has not leaked before operation. Since it is difficult to understand the difference from the leak of the filter, it takes a lot of time to investigate the cause.
By externally attaching the filter mounting bracket (1) to the outside of the casing, the gap between the casing (3) and the casing (4) and the filter (8) can be minimized, and this problem can be solved.
Since the housing is a thin plate structure, the mounting bracket (1) is installed near the rising part of the housing to increase the strength against the load applied when the filter is tightened, so the filter (8) is securely fixed. Is possible.
Further, since the filter bracket (2) presses the packing attached to the filter (8) by line contact, it is possible to surely prevent air leakage with a small fastening force, and load on each part of the housing Since the housing can be manufactured with a thin plate, the weight can be reduced and the workability can be improved.
Punching having various shapes such as a plane and a trapezoid can be attached to the folded end surface portion (5) of the housing.
