【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0003]

【産業上の利用分野】本発明は、各種の集塵機に使用して好適な平板状フイルタの構造に関するものである。 The present invention relates to uses for various dust collectors relate structure suitable flat filter.

【0002】 [0002]

【従来の技術】多数のヒダを横方向に連続形成した平板状フイルタには、従来より図8に示したように断面ヒシ形のヒダ10aを連続形成したもの、或は、図12に示すように断面円形のヒダ13…を連続形成したものが存在し、特にヒシ形のヒダ10aの場合は、図9に示したx寸法に対するy寸法の比率を小さくすれば、袋状(バグ状)或は円筒状に形成した在来のフイルタに比較して、集塵機内に多くのフイルタ面積を実装できる特長を備えており、更に、断面円形のヒダ13…の場合は、x BACKGROUND OF THE INVENTION Numerous flat filter which folds the laterally continuous form, a cross-section water chestnut-shaped folds 10a as shown in FIG. 8 conventionally a continuum formed, or, as shown in FIG. 12 the circular cross section of the folds 13 ... there is a continuum formed, especially if the folds 10a sebum type, by reducing the ratio of y-dimension relative to x-dimension shown in FIG. 9, a bag-shaped (like bugs) some is compared to a conventional filter formed in a cylindrical shape, has a feature that can implement many of the filter area in the dust collector, further, in the case of circular cross-section folds 13 ... of, x
寸法とy寸法が同一で強度的に安定している特長を備えている。 Dimensions and y dimensions are provided with a feature that the strength stable identical.

【0003】而して、図8に於いて、(イ)と(ロ)は断面ヒシ形のヒダ10a…を横方向に連続形成した従来の平板状フイルタ10の正面図と側面図を示したものであって、これ等の図面に於いて11と12は平板状フイルタ10の両端部に固着した補強用の樹脂板である。 [0003] Thus, in FIG. 8, showing the with (b) is a front view of a conventional flat filter 10 which is formed continuously sectional chestnut-shaped folds 10a ... laterally side view (b) it is those, 11 and 12 in this and the like of the drawings is a resin plate for reinforcement fixed to the opposite ends of the plate-like filter 10.

【0004】 [0004]

【発明が解決しようとする課題】ところが、上述したヒシ形のヒダ10aを連続形成した平板状フイルタ10の場合、フイルタ10の各ヒダ10aには濾過時に図9に示した矢印の如く外圧が加わり、パルスジェット払い落し時には反対方向に内圧が加わってヒダ10aが変形するため、図9に示したヒシ形のx寸法とy寸法とが異なる場合には、外圧(内圧も同じ)はx方向面とy方向面とで受圧面積が相違して荷重の差が生じ、図10の(イ)に示すように外圧によってヒシ形のヒダ10aを押し潰したり、反対に図10の(ロ)に示すように内圧によってヒダ10aを押し広げてしまって、その結果、 [SUMMARY OF THE INVENTION However, in the case of flat filter 10 which folds 10a sebum type described above were continuously formed, each fold 10a of the filter 10 is external pressure as indicated by the arrow shown in FIG. 9 joined filtration since at the time of pulse jet pay off the pleats 10a subjected to any internal pressure in the opposite direction is deformed, when the sebum-shaped x-dimension and y-dimension of FIG. 9 differs from, external pressure (internal pressure) is a virtual x-direction plane the difference between the load caused by the pressure receiving area is different between the y-direction plane, shown in or crushed folds 10a of the water chestnut shaped by external pressure as shown in (b) of FIG. 10, in FIG. 10 in the opposite (b) gone to push the folds 10a by internal pressure so that, as a result,
図8の(ロ)に示す如くフイルタ10の全体を湾曲してしまう問題があった。 There is a problem that curved the entire filter 10 as shown in (b) of FIG.

【0005】そこで従来は、フイルタ10の両端部に図8の如く比較的厚目に造った樹脂板11,12を固着して、フイルタ10の全体が湾曲しないように補強していたが、このように各フイルタ10に補強用の樹脂板1 [0005] Therefore the prior art, by fixing the resin plate 11, 12 made in relatively thick eyes as shown in FIG. 8 at both ends of the filter 10, the whole of the filter 10 has been reinforced so as not to bend, this as resin plate 1 for reinforcing the respective filter 10
1,12を固着するのでは、フイルタ10の製造コストを高くする問題があり、且つ、この樹脂板11,12を固着する分だけフイルタ10の表面積を少くする問題があった。 Than securing the can 1 and 12, there is a problem of increasing the manufacturing cost of the filter 10, and had a surface area the problem of less of an amount corresponding filter 10 to fix the resin plate 11 and 12.

【0006】尚、x方向面とy方向面とで受ける荷重の差はx:yの寸法比によって異なるが、図11は一般的な集塵機のフイルタが受ける外圧力を100mmH 2 [0006] The difference of the load received by the x-direction plane and y-direction surface x: varies depending on the size ratio of y, FIG. 11 100 mm H 2 O to outer pressure of general dust collector filter is subjected
(100Kg/m 2 )とした場合に、フイルタ長さ1m In case of the (100Kg / m 2), filter length 1m
当りに受けるy/xの比率に対する荷重の差を表にしたものであって、この表からy/x=1の時が荷重の差がゼロで、どちらからの力に対しても強いことが判明した。 The difference between the load on the ratio of y / x experienced per be one obtained by the table, the difference between the load when the y / x = 1 From this table is zero, is stronger against the force from either found.

【0007】また、図12に示すようにフイルタの各ヒダ13を円形にした場合は、x寸法とy寸法が同一で強度的に最も安定しているが、反面、フイルタ外面へのダストの付着とか、パルスジェット払い落し時に於ける必要な隙間を考慮に入れると、単位空間当りのフイルタ実装表面積が減少する問題があった。 [0007] In the case where the respective folds 13 of the filter in a circle as shown in FIG. 12, but x-dimension and y-dimension is the strength the most stable at the same, contrary, adhesion of dust to the filter outer surface Toka, taking into account the necessary clearance at the time of pulse jet dust removal, filter implementation surface area per unit space there was a problem to decrease.

【0008】従って本発明の技術的課題は、平板状フイルタの両端部に補強用の樹脂板を固着しなくても、平板状フイルタの各ヒダ自身に外圧及び内圧に対して充分な強度性を持たせて、変形を防止することである。 [0008] The technical problem of the present invention therefore, without fixing a resin plate for reinforcing the end portions of the flat filter, sufficient strength against external pressure and the internal pressure in each fold its flat filter made to have, and to prevent deformation.

【0009】 [0009]
