At present, common filter core mostly is the cylindrical shape filter core that filtering material is folded into pleat, and the height of all pleats equates.In actual dust removal process, the load that bear the filter core windward side is large, the load that lee face bears is little, and traditional high cylindrical filter sleeves windward side of pleat of waiting equates with the filter area of lee face, this structure is when using, can't increase to greatest extent the filter area of windward side on the one hand, also cause on the other hand the waste of lee face filter area.
In addition, during deashing, be deposited in dust in the filter core folded seam and relatively be difficult to remove, the filter cylinder dust granules that blows off in top is deposited on the filter cylinder of bottom in addition, has increased the difficulty of deashing.
Summary of the invention
The objective of the invention is to overcome the defective that the high cylindrical shape filter core that equates of the pleat that has all pleats in the heavy streaming filter cartridge dust remover now exists, and a kind of capable of prolonging service life of filter elements be provided, increase whole filter core and windward side filter area, alleviate the deashing difficulty, and then improve filter efficiency cover that filter cloth and pleat are high to be the oval cylinder filter core that echelon distributes outward.
A kind of filter core for heavy streaming filter cartridge dust remover provided by the present invention comprises elliptical porous cylinder core 1, pleat type filter course 2 and overlays on the thick effect filter cloth 3 of pleat type filter course periphery; Described pleat type filter course 2 is the oval tubular structure of similar star, described pleat type filter course 2 is folded into pleat by the filtrate of certain-length, head and the tail are bonded, the inward flange of all pleats is distributed on the excircle of described elliptical porous cylinder core 1, pleat is high to distribute about the ellipse short shaft symmetry, and the corresponding side pleat height of the every side semi-major axis of minor axis all is
