Utility model content
Technical problem to be solved in the utility model is: provide a kind of multilayer ultra high efficiency to hold dirty oil suction filter bag.
The utility model technical problem solves by following proposal: a kind of multilayer ultra high efficiency is held dirty oil suction filter bag, formed by multiple filtration bag, marsupial body, the bag end and sack, sack is fixed on ring, wherein: described multiple filtration bag is sequentially made up of spunbond clad, the folding secondary bag of pre-filtering and main filter bag from inside to outside, wherein
The folding secondary bag upper and lower opening of described pre-filtering, formed by spunbond layer inner protective layer and polypropylene melt-blown folding of material, the folding area increasing is no less than the area corresponding to diameter of the folding secondary bag of described pre-filtering, and the sealing cap that the lower end of the described folding secondary bag of pre-filtering is made by identical filtrate seals;
Described main filter bag comprises: be made up of spunbond interior external protection and two layers of above main filter course, the folding secondary bag of described pre-filtering is placed in main bag by spunbond layer integral coating, and spunbond layer extends to main sack.
The folding secondary bag of pre-filtering of the present utility model can form by high grammes per square metre polypropylene melt-blown filtrate is folding, and the area that folding filtrate increases reaches one times more than, has therefore greatly increased and has held dirty and oil suction area.Main bag is played to good pre-filtering and protective effect simultaneously, increase the service life of whole filter bag.
On such scheme basis, the each filter course of described main filter bag adopts gradient filtration structure, and filtrate flow, to from inside to outside, flows to high-precision filter material layer by the low precision filtered bed of material.Reach the technique effect of accurate filtration.
On such scheme basis, the each filter course of described main filter bag adopts the mode of linear slit to sew up the each filter course side seam of main bag, end seam and sealing cap.
On such scheme basis, described sack is integral with ring integral solder.
Superiority of the present utility model is: the area that the folding filtrate of the described folding secondary bag of pre-filtering increases reaches one times more than, has therefore greatly increased and has held dirty and oil suction area.Main bag is played to good pre-filtering and protective effect simultaneously, increase the service life of whole filter bag.
In addition, the increase of filter area means that rate of flow of fluid slows down, and initial drop declines, and effectively saves the energy; Fluid and fiber are long time of contact, improve fiber capturing greasy dirt effect.
Described main bag adopts the form of gradient filtration, and filtrate flow is to from inside to outside, and the multilayer filtrate of main bag, flows to high-precision filter material by low precision filtrate, ensures filtering accuracy and service life of fine and close filter course.
