Abstract

The utility model relates to a cylindrical or square multi-layer filter cartridge used for an engine and consists of two end covers, an internal filter screen, an external filter screen, an internal filter paper and an external filter paper. The two end covers, the internal filter screen and the external filter screen form the frame of the filter cartridge; the filter paper is folded longitudinally, the folding spacing and the density of the internal and external filter papers are different but the amount of the folding layers are corresponding, the density of the filter paper can be decided according to the filtered object of the engine; the two layer or multilayer filter paper of the internal filter paper and the external filter paper which are folded are placed between the internal filter screen frame and the eternal filter screen frame; each folding layer is all engaged with each other mutually, the engaging end has certain clearance, the other end is overlapped so that the double layer and multilayer filter papers support each other; finally, the two end covers are adhered with the internal and external filter screens to form the filter cartridge by a binder; when the filtering object passes the outer filter payer, the grains is filtered, and the filtering object is purified completely after passing through the internal filter paper; The utility model has simple structure, long service life, good filtering effect and wide application fields.

Description

Motor Vehicle multiple filtration filter element

Affiliated technical field

The utility model relates to a kind of Motor Vehicle multiple filtration filter element, is mainly used in the filtrating equipment of various motor vehicle engines.

Background technique

At present, the employed filtration filter element of Motor Vehicle, the filtration filter element that all adopts single layer filter paper to make, so in filter process, the impurity in the materials such as its institute's filtered air, machine oil, fuel oil, size of grain no matter, filter by single layer filter paper, be easy to cause filter paper to stop up and breakage, make the working life of whole filtration filter element short, and poor filtration effect, motor is caused damage.

Summary of the invention

In order to overcome above-mentioned deficiency, the utility model provides a kind of Motor Vehicle multiple filtration filter element through development, improves working life, strengthens filtering effect, and filter paper is cracky not, the normal operation of better protection motor.

The technological scheme that its technical problem that solves the utility model adopts is: it is mainly by the two ends end cap, inside and outside net, and inside and outside layer filter paper formed, and shape is cylinder type or square.On the basis of filtration filter element profile that does not change original Motor Vehicle use and skeleton, only change the structure of its filter layer.The two ends end cap and the inside and outside net that adopt metal, plastics or oil resistant rubber to make constitute and filter the filter element skeleton.Filter paper is carried out longitudinal foldingly, the folding of inside and outside layer filter paper is apart from close inequality again, but the foldable number of foldable layer is corresponding, and the size of filter paper density can be determined according to the material that motor filtered.The inside and outside layer filter paper bilayer or the multilayer that fold are implanted between the inside and outside network framework, and each foldable layer is interlock mutually all, and an end of interlock leaves the gap mutually, and the other end is overlapping, and bilayer or multiple filtration paper are supported mutually.At last the two ends end cap is sealed with Bond and inside and outside net, form and filter filter element.Impurity in filtering material, particle is filtered during through outer filter paper, when passing through the internal layer filter paper again, reaches the purpose of thorough pure filtration.

The beneficial effects of the utility model are: this Motor Vehicle multiple filtration filter element, and good filtration effect, long service life, after the breakage of outer filter paper, the internal layer filter paper is still brought into play filtration, and normal operation plays a protective role to motor.It is simple in structure, does not increase manufacturing process, and applied range is suitable for to vigorously promote the use.

Embodiment

Embodiment 1, see also Fig. 1 to Fig. 3, a kind of Motor Vehicle multiple filtration filter element, it is by two ends end cap (1), inside and outside net (2), (3), inside and outside layer filter paper (4), (5) are formed, and shape is cylinder type or square.On the basis of filtration filter core profile that does not change original Motor Vehicle use and skeleton, only change the structure of its filter layer.Two ends end cap (1) and inside and outside net (2), (3) are adopted metal, plastics or oil resistant rubber to make and are filtered the filter element skeleton.Carry out longitudinal folding with paper folder filter paper, make internal layer filter paper (4) and outer filter paper (5), the folding of inside and outside layer filter paper is apart from inequality with density, but the foldable number of foldable layer is corresponding, and the big I of filter paper density is determined according to the motor desired substance.The density of internal layer filter paper (4) is greater than the density of outer filter paper (5); In the filter paper implantation of the inside and outside layer filter paper (4), (5) bilayer or the multilayer that fold, between the skeleton of outer net (2), (3); The folding distance of outer filter paper (5) is less than internal layer filter paper (4), the mutual interlock of each foldable layer and foldable layer, an end of interlock leaves inside and outside interocclusal clearance (6) mutually, side near Intranet (2), the other end internal and external layer interlock overlapping (7), near a side of outer net (3), the binding site (8) of interlock supports two-layer filter paper in the outside mutually mutually.End cap (1) with two ends seals with Bond and inside and outside net (2), (3) at last, forms to filter filter element.

Embodiment 2, two ends end cap (1) and in, outer net (2), (3) the filtration filter cleaner skeleton of making is constant, identical with above-mentioned technology, the setting of its filter layer only at the folding of outer filter paper (5) apart from greater than internal layer filter paper (4), the gap (6) of the mutual interlock of foldable layer of outer filter paper (5) and internal layer filter paper (4) is near a side of outer net (3), the overlapping (7) of outer filter paper (5) and mutual interlock one end of internal layer filter paper (4) foldable layer is near a side of Intranet (2), and the binding site (8) of outer filter paper and the mutual interlock of internal layer filter paper foldable layer is in the inboard.
