本考案は、圧力損失の少ない多重Ｖ型プリーツ
構造のエアフイルタに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air filter having a multi-V pleat structure with low pressure loss.
従来、この種のエアフイルタは材をプリーツ
状に折りたたんで作製されており、例えば第５図
に示した様に矩形状のプリーツパネル２の複数枚
をジグザグ状に配し、互いに隣接するプリーツパ
ネル２の頂面を平板形状のホルダー３′，４′によ
り固定封泥している。 Conventionally, this type of air filter has been manufactured by folding material into a pleat shape. For example, as shown in FIG. The top surface of the holder is fixedly sealed with flat plate-shaped holders 3' and 4'.
このプリーツパネル２は、材を20〜50mm巾で
プリーツ状に折りたたみながらプリーツの原形を
保持し、かつ材の補強を行なうために適当な巾
と厚みのセパータ（図示せず）を各プリーツの間
に折り込んで、材を一様な間隔に保ち、空気の
通風を良くしたものである。 This pleated panel 2 is made by folding the material into pleats with a width of 20 to 50 mm while maintaining the original shape of the pleats, and inserting separators (not shown) of appropriate width and thickness between each pleat to reinforce the material. It is folded over to keep the pieces at even intervals and improve air ventilation.
したがつて、上記多重Ｖ型プリーツ構造のエア
フイルタは、容積に比べて材面積が大きく大風
量の過に適している。 Therefore, the air filter having the multiple V-type pleat structure has a large surface area compared to its volume and is suitable for large air volumes.
しかしながら、ジグザグ状に配したプリーツパ
ネル２の頂面を固定封泥するホルダー３′は、通
常６〜８枚使用されており、このホルダー３′に
よる圧力損失が意外と大きく、材面積の割には
風量を上げ難いという問題点があつた。これは、
いわゆる構造圧損は処理風量の２乗に比例するの
で、風量が大きくなるとホルダー３′による構造
圧損が急激に増加するためと考えられる。 However, six to eight holders 3' are usually used to fix and seal the top surfaces of the pleated panels 2 arranged in a zigzag pattern, and the pressure loss due to these holders 3' is surprisingly large, considering the area of the material. The problem was that it was difficult to increase the air volume. this is,
This is considered to be because the so-called structural pressure loss is proportional to the square of the processing air volume, so as the air volume increases, the structural pressure loss due to the holder 3' increases rapidly.
本考案は、上記従来例の難点を解消するために
なされたものであり、その目的とするところは、
材面積に全く変化を与えることなしに処理風量
が大きい場合の圧力損失を大巾に低減させたエア
フイルタを提供することにある。 The present invention was devised to solve the drawbacks of the conventional example, and its purpose is to:
It is an object of the present invention to provide an air filter that greatly reduces pressure loss when a large amount of air is processed without changing the material area at all.
本考案の基本的構成は、互いに隣接するプリー
ツパネルの上流側及び下流側の頂面を通風抵抗の
少ない形状のホルダーにより固定封泥したもので
ある。 The basic structure of the present invention is that the top surfaces of the upstream and downstream sides of adjacent pleated panels are fixed and sealed with a holder having a shape that reduces ventilation resistance.
以下、本考案の構成を一実施例として示した図
面に従つて説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be explained below with reference to the drawings showing one embodiment.
第１図は、エアフイルタ本体１の一部切欠斜視
図であり、矩形状のプリーツパネル２の複数枚を
ジグザグ状に配し、互いに隣接するプリーツパネ
ル２の上流側及び下流側の頂面を、ホルダー３，
４により固定封泥して、枠５内に取り付けてい
る。 FIG. 1 is a partially cutaway perspective view of an air filter body 1, in which a plurality of rectangular pleated panels 2 are arranged in a zigzag pattern, and the top surfaces of adjacent pleated panels 2 on the upstream and downstream sides are held by a holder 3,
It is fixed and sealed with mud by 4 and attached within the frame 5.
上流側のホルダー３は、第３図に示した如く外
面を円弧形状３ａ、又は山形状、放物線形状等の
通風抵抗の小さい形状としている。 As shown in FIG. 3, the upstream holder 3 has an outer surface having a circular arc shape 3a, a mountain shape, a parabolic shape, or other shape with low ventilation resistance.
したがつて、第５図に示す様に従来の平板形状
のホルダー３′では空気の流れに著しい渦流を生
じかなりの通風抵抗があつたが、本考案ではホル
ダー３を上記の形状としたため、渦流が生ずるこ
となく通風抵抗は小さくなり圧力損失をかあり低
減することができた。 Therefore, as shown in Fig. 5, with the conventional holder 3' having a flat plate shape, significant vortices were generated in the air flow, resulting in considerable ventilation resistance.However, in the present invention, the holder 3 is shaped as described above, so that the vortices are reduced. The ventilation resistance was reduced and the pressure loss was significantly reduced without causing any problems.
すなわち、標準サイズ610H×610W×292Dmm6V
タイプ（プリーツパネルの12枚をジグザグ状に配
してＶ形を６組構成したもの）のフイルタ（定格
風量50m3／min）の場合、上流側のホルダー３を
第３図の如く外面を円弧形状３ａにすることによ
り、圧力損失は従来の25mmWGから約２mmWG低
下した。このエアフイルタの定格風量を処理する
際の風速は、計算によれば約2.26m／secであ
る。 That is, standard size 610 H × 610 W × 292 D mm6V
In the case of a filter (rated air volume 50m 3 /min) of the type (12 pleated panels arranged in a zigzag pattern to form 6 sets of V-shapes), the upstream holder 3 has an arcuate outer surface as shown in Figure 3. By adopting shape 3a, the pressure loss was reduced by approximately 2 mmWG from the conventional 25 mmWG. According to calculations, the wind speed when processing the rated air volume of this air filter is approximately 2.26 m/sec.
又、下流側のホルダー４は、第４図に示した如
く内面を山形状４ａ、又はその他の通風抵抗の小
さい形状としている。 Further, the holder 4 on the downstream side has an inner surface formed into a mountain shape 4a, as shown in FIG. 4, or other shapes with low ventilation resistance.
したがつて、第５図に示す様に従来例の平板形
状のホルダー４′では、下流側でも空気の流れに
著しい渦流を生じかなりの通風抵抗があつたが、
本考案ではホルダー４を上記の形状としたため、
渦流が生ずることなく通風抵抗は小さくなり、圧
力損失をさらに低減することができた。 Therefore, as shown in FIG. 5, in the conventional flat plate-shaped holder 4', a significant vortex was created in the air flow even on the downstream side, creating considerable ventilation resistance.
In the present invention, since the holder 4 has the above shape,
Ventilation resistance was reduced without the generation of eddy currents, and pressure loss could be further reduced.
この下流側のホルダー４の形状により、前記標
準サイズのフイルタ6Vタイプでは、圧力損失を
さらに約３mmWG低下させることができた。 Due to the shape of the holder 4 on the downstream side, it was possible to further reduce the pressure loss by about 3 mmWG in the 6V type filter of the standard size.
尚、本考案では第４図に鎖線で示した如く、下
流側のホルダー４の外面を円弧形状４ｂ、又はそ

が更に約１mmWG低下するという作用効果が認め
られた。 In addition, in the present invention, as shown by the chain line in Fig. 4, if the outer surface of the holder 4 on the downstream side is made into a circular arc shape 4b or other shape with low ventilation resistance, the pressure loss can be further reduced by about 1 mmWG. was recognized.
これは、従来の平板形状のホルダー４′の下流
側において、その外面に生ずる若干の渦流を防止
したことによるものと考えられる。 This is thought to be due to the prevention of some eddy currents occurring on the outer surface of the conventional flat plate-shaped holder 4' on the downstream side.
以上に示した如く、本考案は、その材面積に
全く影響を与えることなく大風量を処理する際の
圧力損失を大巾に低減させ、エネルギーの省力化
を図ることのできるものである。 As described above, the present invention can significantly reduce pressure loss when processing a large air volume without affecting the area of the material at all, and can save energy.
