Description

A kind of corrugated filter core

Technical field

The utility model relates to filtration core, in particular to a kind of corrugated filter core.

Background technique

Since the effective filtration area of conventional bag filtration system is very limited, and filter bag has biggish hold-up volume, Gradually consider to use cylindrical fold formula filter cylinder or spiral shape pleated filter element in the market, but at the periphery of filter element Adjacent pleats between there are still a large amount of free spaces.Particularly, spiral shape pleated filter element includes multiple with cylinder Shape construction setting longitudinal fold, the end of fold is rolled so that close to the adjacent pleats face at filter element outer diameter it Between interval minimize, thus than traditional radial fold building have bigger filter table area.But previous spiral shape More free space is still remained at the periphery of pleated filter, this makes corrugations ends activity more flexible, when to mistake Filtrate body easily washes certain end of fold open when passing through filter, can not make full use of all folds and affect filtering Effect also causes waste.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of a kind of pleats reasonable in design, filter effect is good Wrinkle filtration core.

It is as follows that the utility model solves technical solution used by above-mentioned technical problem:

A kind of corrugated filter core described in the utility model, a kind of corrugated filter core are annulus cylindricality, and feature exists In: including an outer cylinder, the outer cylinder includes multiple circumferentially distributed outer folds and longitudinally extends, and the outer fold is around described outer Cylinder perimeter is uniformly distributed, and the outer fold is kyrtom, and the outer fold includes spaced macrofold and wrinkling, respectively The macrofold has an equal arc length, and each wrinkling has an equal arc length, the macrofold and adjacent thereto small Fold is partially overlapped by each other, and greatly increases filter area, reduces the free space of filtration core, enhances filter effect, filtration core Fold is fully used, and materials are saved, reduce cost.

Further, the arc length ratio of the macrofold and wrinkling overlapping is 8:5, not only more reduces the sky of filtration core Free space, moreover it is possible to which more firm fold is allowed to be not susceptible to be displaced, and enhances filter effect.

Further, a kind of corrugated filter core further includes an inner cylinder, and the inner cylinder nesting is in the outer cylinder, described Inner cylinder includes multiple circumferentially distributed inner folds and longitudinally extends, and the inner folds are uniformly distributed around the inner cylinder perimeter, institute Stating inner folds is kyrtom, and each inner folds have equal arc length, not only reduces the free space of filtration core, moreover it is possible to steady Gu fold is allowed to be not susceptible to be displaced, enhance filter effect.

Further, the inner folds with macrofold is spaced circumferentially from one another separates, the inner folds are close to outer cylinder periphery One end and macrofold cooperate far from one end shape of outer cylinder periphery, more reduce the free space of filtration core, moreover it is possible to more steady Gu fold is allowed to be not susceptible to be displaced, keep filter effect stronger.

Preferably, a kind of corrugated filter core further includes branch fold, and the branch fold is positioned close to outer cylinder periphery One end of macrofold or wrinkling, the branch fold are uniformly distributed around the outer cylinder perimeter, and the branch fold is kyrtom, Each branch fold has equal arc length, and the branch fold and macrofold adjacent thereto or wrinkling are partially overlapped by each other, Keep the contact area of corrugated filter bigger, more firm fold is allowed to be not susceptible to be displaced, to enhance filter effect.

Further, the arc length ratio of branch fold and macrofold lap adjacent thereto is 1:8, branch fold and therewith phase The arc length ratio of adjacent wrinkling lap is 1:5, not only materials saving, moreover it is possible to which the free time for maximumlly reducing filtration core is empty Between, and can more consolidate fold, be allowed to be not susceptible to be displaced, enhance filter effect.

The utility model compared with the existing technology has the following advantages that and effect: considerably increasing filter area, reduced The free space of filter core enhances filter effect, while can also more consolidate fold, be allowed to be not susceptible to be displaced, and filtration core Fold is fully utilized, and materials are saved, reduce cost.
