Description

本発明は工場空調、ビル空調あるいはガスタービン吸気などのプレフィルターあるいは中高性能フィルターとして使用されるポケット形エアフィルターに関するものである。  The present invention relates to a pocket type air filter used as a pre-filter or medium-high performance filter for factory air-conditioning, building air-conditioning or gas turbine intake.

従来のポケット形エアフィルターは、一体式の取り付け枠と、複数枚の袋状フィルター濾材からなり、接着剤を使用して袋状フィルター濾材を１枚ずつ取り付け枠に接着している。使用後は取り付け枠と袋状フィルター濾材を一体にて廃棄処分している。  A conventional pocket-type air filter is composed of an integral mounting frame and a plurality of bag-shaped filter media, and the bag-shaped filter media are bonded to the mounting frame one by one using an adhesive. After use, the mounting frame and the bag-shaped filter media are disposed of as a unit.

上記の袋状フィルター濾材接着工程において接着剤に有機溶剤が含まれており、ポケット形エアフィルター製作時の作業環境が劣悪であり、別途局所排気等の処置が必要でコスト高となっていた。また、接着剤が固化するまでに時間がかかり、生産性が上がらない問題があった。  In the bag-shaped filter medium adhering step, the adhesive contains an organic solvent, and the working environment at the time of manufacturing the pocket-type air filter is inferior. In addition, there is a problem that it takes time until the adhesive is solidified and the productivity does not increase.

また、使用後のエアフィルターを処分する際にも、取り付け枠とフィルター濾材が強固に接着されているため、例えば分別廃棄を実施する際に、金属製の取り付け枠と、ガラス繊維又は合成繊維製のフィルター濾材を分解するのに非常に手間がかかっていた。
上記の問題を解決するため、接着剤を使用せずに、取り付け枠を二重構造としてフィルター濾材をはめ合わせる方法がある。しかし本方法でははめ合わせたフィルター濾材を固定するヘッダー部品が別途必要となり、コスト高となる問題があった。In addition, when disposing of the used air filter, the attachment frame and the filter medium are firmly bonded. For example, when separating and discarding, a metal attachment frame and glass fiber or synthetic fiber are used. It took a lot of time to disassemble the filter media.
In order to solve the above problem, there is a method in which the filter medium is fitted to the mounting frame with a double structure without using an adhesive. However, this method requires a separate header part for fixing the fitted filter medium, which increases the cost.

発明が解決しようとする課題Problems to be solved by the invention

まず本発明の目的は、接着剤を使用することなく取り付け枠に袋状フィルター濾材を複数個取り付けられるようにしたポケット形エアフィルターを提供しようとしたものである。  First, an object of the present invention is to provide a pocket-type air filter in which a plurality of bag-shaped filter media can be attached to an attachment frame without using an adhesive.

次に本発明の目的は、取り付け枠に複数個の袋状フィルター濾材を簡単な作業で容易に組み立てられるようにしたポケット形エアフィルターを提供しようとしたものである。  Next, an object of the present invention is to provide a pocket-type air filter in which a plurality of bag-shaped filter media can be easily assembled on a mounting frame by a simple operation.

さらに本発明の目的は、取り付け枠から袋状フィルター濾材を簡単に取り外し可能にし且つ容易に分別廃棄できるようにしたポケット形エアフィルターを提供しようとしたものである。  A further object of the present invention is to provide a pocket-type air filter in which the bag-shaped filter medium can be easily removed from the mounting frame and can be easily separated and discarded.

また本発明の目的は、袋状フィルター濾材の寿命を長寿命となるように取り付けられるようにしたポケット形エアフィルターを提供しようとしたものである。  Another object of the present invention is to provide a pocket-type air filter that can be attached so that the life of the bag-shaped filter medium is long.

課題を解決するための手段Means for solving the problem

本発明の第１の解決手段は、複数個連接した袋状フィルター濾材と袋状フィルター濾材を支持固定する格子状内枠と格子状内枠に嵌合する格子状外枠とから構成したことを特徴としたものである。  The first solving means of the present invention comprises a plurality of connected bag-shaped filter media, a grid-shaped inner frame for supporting and fixing the bag-shaped filter media, and a grid-shaped outer frame fitted to the grid-shaped inner frame. It is a feature.

本発明の第２の解決手段は、格子状内枠の側面に貼り付けた両面テープにより袋状フィルター濾材を格子状内枠に保持するようにしたことを特徴としたものである。  The second solving means of the present invention is characterized in that the bag-shaped filter medium is held on the lattice-shaped inner frame by a double-sided tape affixed to the side surface of the lattice-shaped inner frame.

本発明の第３の解決手段は、格子状外枠のツメを格子状内枠の外面に折り返すことにより格子状内枠を固定するようにしたことを特徴としたものである。  The third solving means of the present invention is characterized in that the lattice-shaped inner frame is fixed by folding back the claws of the lattice-shaped outer frame to the outer surface of the lattice-shaped inner frame.

ここで、袋状フィルター濾材は２枚の長方形の濾材を重ね合わせ、一側縁を除いて他の側縁部を覆い布で挟み覆い布の上から糸で縫い合わせて袋状にしたものである。  Here, the bag-shaped filter medium is formed by stacking two rectangular filter media, excluding one side edge, sandwiching the other side edge part with a covering cloth, and sewing it with a thread from the covering cloth to form a bag shape. .

袋状フィルター濾材の一側縁は気体流入口の機能を有する開口部が形成されている。さらにこの開口部縁部には補強布が縫い付けられ濾材と一体化されている。そして隣接した開口部縁部は補強布と共に糸で縫い合わされ複数個の袋状フィルター濾材が連結縫製されている。さらに袋状フィルター濾材には長、短尺縫合線が設けられ、袋状フィルター濾材が送風により膨んでも互いに接触し、気流が流れにくくなったり、濾材面が摩擦や損傷したりするのを防止している。  An opening having a function of a gas inlet is formed on one side edge of the bag-shaped filter medium. Further, a reinforcing cloth is sewn on the edge of the opening and integrated with the filter medium. Adjacent opening edges are sewn together with a reinforcing cloth with a thread, and a plurality of bag-shaped filter media are connected and sewn. In addition, the bag-shaped filter media are provided with long and short suture lines to prevent the bag-shaped filter media from coming into contact with each other even when blown by blowing, preventing the airflow from flowing and preventing the filter media from being frictioned or damaged. ing.

そして本発明に使用される袋状フィルター濾材は例えば部材としては、ガラスマット、合成繊維不織布またはメルトブロー法による極細繊維とガラスマットの積層品、混紡品または極細繊維と合成繊維不織布の積層品、混紡品などが使用できる。  The bag-shaped filter medium used in the present invention includes, for example, a glass mat, a synthetic fiber nonwoven fabric, a laminate of ultrafine fibers and a glass mat by a melt blow method, a blended product, or a laminate of ultrafine fibers and a synthetic fiber nonwoven fabric, and a mixed spinning. Goods can be used.

また濾材密度は従来より袋状フィルター濾材として使用されてきたものがそのまま使用でき、特に限定されるものではない。一般的には５０〜３７０ｇ／ｍ２で、その中でも６０〜２００ｇ／ｍ２がさらに良い。
濾材の厚みも、従来の袋状フィルター濾材として使用されてきたものがそのまま使用でき、特に限定されるものではない。一般的には５〜２０ｍｍで、その中でも５〜１０ｍｍがさらに良い。In addition, the density of the filter medium is not particularly limited, and it can be used as it is as a bag-shaped filter medium. Generally, it is 50-370 g / m < 2 >, and 60-200 g / m < 2 > is still better among them.
The thickness of the filter medium is not particularly limited as long as it can be used as it is as a conventional bag filter medium. Generally, it is 5-20 mm, and 5-10 mm is still better among them.

そして、覆い布の幅は濾材の側縁部がほぐれることなく、気流の流れに障害とならない程度の細いものが好ましい。さらに袋状フィルター濾材に合成繊維不織布を使用した場合は、縫製の代わりに熱溶着加工を行うことも可能である。  And the width | variety of a covering cloth is preferable so that the side edge part of a filter medium may not be loosened, and it may not become an obstacle to the flow of airflow. Furthermore, when a synthetic fiber non-woven fabric is used for the bag-shaped filter medium, it is possible to perform heat welding instead of sewing.

次に格子状内枠は袋状フィルター濾材の数に１つ少ない数の格子桟と外周囲枠とからなり、格子桟と外周囲枠とも凸部あるいはコの字状あるいは矩形状枠となっている。そして外周囲枠の側面には全周又は部分的に両面テープが貼り付けられている。さらにエアーの流れの下流側方向より格子状内枠を袋状フィルター濾材に嵌め込んだとき、格子状内枠の上面が袋状フィルター濾材の開口部縁部及び補強布に当接するようになっている。この状態から開口部縁部及び補強布を格子状内枠の外周囲枠の側面方向に折り返して開口部縁部及び補強布を両面テープに貼り付けることにより、格子状内枠に袋状フィルター濾材がシワ等がなく保持されるようになっている。
ここで格子状内枠の形状を凸部あるいはコの字状あるいは矩形状としたがこれに限定されることなく、格子状内枠の形状は格子状外枠に嵌合した時、袋状フィルター濾材の開口部縁部および補強布に当接するように形成されていれば種々変更しても何ら本発明の要旨を変更するものではない。Next, the grid-like inner frame is composed of a grid bar and an outer peripheral frame, which is one less than the number of bag-shaped filter media, and both the grid bar and the outer peripheral frame are convex, U-shaped or rectangular frames. Yes. And the double-sided tape is affixed to the side surface of the outer periphery frame entirely or partially. Further, when the lattice-shaped inner frame is fitted into the bag-shaped filter medium from the downstream side of the air flow, the upper surface of the lattice-shaped inner frame comes into contact with the opening edge of the bag-shaped filter medium and the reinforcing cloth. Yes. From this state, the opening edge and the reinforcing cloth are folded back in the lateral direction of the outer peripheral frame of the lattice-shaped inner frame, and the opening edge and the reinforcing cloth are attached to the double-sided tape. However, there is no wrinkle and so on.
Here, the shape of the lattice-shaped inner frame is a convex portion, a U-shape or a rectangular shape, but the shape of the lattice-shaped inner frame is not limited to this. Even if various changes are made as long as they are formed so as to contact the edge of the opening of the filter medium and the reinforcing cloth, the gist of the present invention is not changed.

次に格子状外枠の両側面には折り曲げ自由な各々２つのツメが一体に形成され、ツメの長さは格子状外枠を格子状内枠に嵌合して内側に折り曲げた時格子状内枠の側面まで延びる長さとなっている。  Next, each of the two sides of the lattice-shaped outer frame is integrally formed with two claws that can be bent, and the length of the claw is lattice-shaped when the lattice-shaped outer frame is fitted to the lattice-shaped inner frame and bent inward. The length extends to the side of the inner frame.

次に組み立て手順について説明する。まず複数個連接した袋状フィルター濾材の後方から格子状内枠を嵌め込み、格子状内枠の外周囲枠と格子桟の上面を袋状フィルター濾材の開口部縁部及び補強布にあてがう。次に開口部縁部及び補強布を格子状内枠の外周囲枠の側面方向に折り返し開口部縁部及び補強布を両面テープに貼り付け保持する。次に袋状フィルター濾材の前方向から格子状外枠を格子状内枠に嵌めこむ。そして、格子状外枠のツメを格子状内枠の側面に折り曲げ格子状内枠と格子状外枠とを確実に固定して組み立てる。  Next, the assembly procedure will be described. First, a lattice-shaped inner frame is fitted from the rear side of a plurality of connected bag-shaped filter media, and the outer peripheral frame of the lattice-shaped inner frame and the upper surface of the lattice beam are applied to the opening edge of the bag-shaped filter media and the reinforcing cloth. Next, the opening edge and the reinforcing cloth are folded back in the lateral direction of the outer peripheral frame of the lattice-shaped inner frame, and the opening edge and the reinforcing cloth are attached to and held on the double-sided tape. Next, the lattice-shaped outer frame is fitted into the lattice-shaped inner frame from the front side of the bag-shaped filter medium. Then, the claws of the lattice-shaped outer frame are bent on the side surfaces of the lattice-shaped inner frame, and the lattice-shaped inner frame and the lattice-shaped outer frame are securely fixed and assembled.

上記課題解決手段による作用は次の通りである。すなわちポケット形エアフィルターは袋状フィルター濾材の開口部縁部の補強布を格子状内枠の外周囲枠の側面方向に折り返し補強布を両面テープに貼り付け保持し、さらに格子状外枠のツメを格子状内枠の外面に押し当て格子状内枠と格子状外枠とを固定した構造であるので、上流側からの強い気流の圧力変動や振動あるいは気流の乱れなどにより外力を受けフィルター濾材が離脱することがないようになっている。またフィルター濾材の開口部に流入した気流により袋状フィルター濾材が膨らむが、袋状フィルター濾材は糸で縫い合わせられているので、袋状フィルター濾材の隣同士が接近することによる摩擦や損傷が防止される上、通風時の有効濾過面積が小さくなるのが防止できるものである。  The effect | action by the said problem-solving means is as follows. That is, the pocket-type air filter folds the reinforcing cloth at the edge of the opening of the bag-shaped filter medium in the direction of the side of the outer peripheral frame of the lattice-shaped inner frame, and holds the reinforcing cloth on the double-sided tape. Since the grid inner frame and the grid outer frame are fixed to the outer surface of the grid inner frame, the filter medium receives the external force due to strong air pressure fluctuations, vibrations or air current disturbances from the upstream side. Will not leave. In addition, the bag-shaped filter medium is swelled by the airflow that flows into the opening of the filter medium, but the bag-shaped filter medium is sewn together with thread, preventing friction and damage due to the proximity of the bag-shaped filter medium. In addition, it is possible to prevent the effective filtration area during ventilation from becoming small.

次に長時間の通風により袋状フィルター濾材が目詰まりあるいは所定の使用時間が経過した際には格子状外枠のツメを外側に起し、格子状内枠から取り外す。その後、袋状フィルター濾材の開口部縁部及び補強布を格子状内枠の両面テープから取り外せば済むといった簡単な方法で分別廃棄を可能にしたものである。  Next, when the bag-shaped filter medium is clogged due to long-term ventilation or when a predetermined usage time has elapsed, the claw of the lattice-shaped outer frame is raised outward and removed from the lattice-shaped inner frame. After that, separation and disposal can be performed by a simple method in which the opening edge of the bag-shaped filter medium and the reinforcing cloth can be removed from the double-sided tape of the lattice-shaped inner frame.

(Embodiment)
1 is a bag-like filter medium made of glass fiber. Two rectangular filter media 2, 2 'are overlapped, one side edge is removed, the other side edge is covered with cloth 3, and the cloth 3 is sewn with a thread. It is a bag. Moreover, the opening part which has a function of a gas inflow port is formed in one side edge, and the reinforcement cloth 5 is sewn on this opening part edge part 4. As shown in FIG. Adjacent opening edges 4 are sewn together with a reinforcing cloth 5 with a thread, and a plurality of bag-shaped filter media 1 are connected and sewn. Further, the bag-shaped filter medium 1 is provided with a long suture line 6 and a short suture line 7.

次に８は格子状内枠で格子桟９と外周囲枠１０とからなっている。そして格子桟９と外周囲枠１０は凸部あるいはコの字あるいは矩形状となっている。さらに外周囲枠１０の側面全周には両面テープ１１が貼り付けられている。そして開口部縁部４および補強布はを格子状内枠８の外周囲枠１０の側面方向に折り返して開口部縁部４および補強布５を両面テープ１１に貼り付けることにより保持される。  Next, reference numeral 8 denotes a lattice-shaped inner frame comprising a lattice bar 9 and an outer peripheral frame 10. The grid bars 9 and the outer peripheral frame 10 are convex, U-shaped or rectangular. Further, a double-sided tape 11 is affixed to the entire circumference of the side surface of the outer peripheral frame 10. Then, the opening edge 4 and the reinforcing cloth are folded back in the side surface direction of the outer peripheral frame 10 of the lattice-shaped inner frame 8, and the opening edge 4 and the reinforcing cloth 5 are attached to the double-sided tape 11.

次に格子状外枠１２は格子状内枠８の格子桟９と外周囲枠１０とに対応する位置に形成された格子桟１３と外周囲枠１４からなっている。そして格子桟１３と外周囲枠１４は凹部状となっている。  Next, the lattice-shaped outer frame 12 includes a lattice beam 13 and an outer peripheral frame 14 formed at positions corresponding to the lattice beam 9 and the outer peripheral frame 10 of the lattice-shaped inner frame 8. The lattice bar 13 and the outer peripheral frame 14 are recessed.

さらに格子状外枠１２の外周囲枠１４両側面には各々２つのツメ１５が一体に形成されている。そして格子状外枠１２を格子状内枠８に嵌合した状態で格子状外枠１２のツメ１５を格子状内枠８の外面に押し当てる。これにより格子状内枠８と格子状外枠１２とが確実に密着固定されポケット形エアフィルターが形成される。Further, two claws 15 are integrally formed on both side surfaces of the outer peripheral frame 14 of the lattice-shaped outer frame 12.
