Abstract

The invention discloses a supporting structure and filter element of a filtering structure. The supporting structure comprises a supporting cylinder which is formed by winding a strip-shaped coiled material, the coiled material is of a porous structure, and a joint formed by winding the coiled material is not parallel to the central axis of the supporting cylinder. When the supporting cylinder bears internal and external pressure, the maximum principal stress of the supporting cylinder is perpendicular to the central axis and acts on each round section. According to a traditional straight welded pipe (a joint is parallel to the central axis of the welded pipe), the joint directly bears the maximum principal stress, and the requirement of weld joint strength is high. When the joint is not parallel to the central axis of the supporting cylinder, the joint mainly bears component force of the principal stress, namely radial stress and axial stress, the two stress values are obviously smaller than the principal stress of the straight welded pipe, and therefore the thickness of the supporting structure can be obviously reduced at the same work pressure and the same pipe diameter. The porosity can be obviously increased, so that the effect filtering area of the filtering structure is improved.

Description

technical field [0001] The invention relates to the technical field of filter devices, in particular, to a support structure of a filter structure and a filter element. Background technique [0002] The applicant of the present application has submitted publication numbers respectively CN104874798A (named as porous film and its preparation method), CN104874801A (named as porous film and its preparation method), CN104959612A (named as a porous film and its preparation method). film preparation method), CN104959611A (named porous film and porous film preparation method) patent application, discloses a kind of thickness ≤ 1500 micron and foldable flexible metal film, more preferably when the thickness ≤ 200 micron is easy achieve high air permeability.
