Abstract

The utility model provides an air filter core capable of washing, which is suitable for air filters of various vehicle motors and various internal combustion engines. The utility model is composed of an upper end cover, a lower end cover, an inner protective net, an outer protective net and a filter core which is arranged between the inner protective net and the outer protective net, wherein, the filter core of the utility model is formed by that three layers are integrally continuously folded, and both sides are metallic sieve and the middle part is fiber non-woven filtering cloth. The utility model has strong sandstorm resistance and air filtration performances, the utility model can be carried out washing and be used repeatedly, and the service life and the working property of the air filter core can be enhanced.

Description

The washable air filter core

The utility model relates to a kind of air filtering core that is used on the various explosive motor air filters, particularly a kind of air filtering core that can clean.

At present, be used for the air filtering core on the various explosive motor air filters such as automobile, tractor, engineering truck, all adopt the papery filter core to form.Long-pending full on paper filter element, cause intake resistance to increase to work on owing to dirts such as sand and dust are very fast in the use, but this kind filter core can not clean repeated use, can only disposable use scrap.And this filter core is very easily punctured by the grains of sand in the bigger adverse circumstances of dust storm and influences the air-filtering effect.Therefore, its service life is too short, and loss is bigger.

The purpose of this utility model is will provide a kind of can clean and reusable air filtering core, to improve its service life and reliable service behaviour.

The utility model is realized by following scheme:

This air filtering core is by upper end cover, bottom end cover, interior protecting wire net, outer protecting wire net and place the filter core between inside and outside protecting wire net to form, and is characterized in that filter core is is that to be that three layers of one of fiber non-woven filter cloth are folding continuously in the middle of the metallic sieve form by both sides.

The utility model air filtering core is that the metallic sieve centre is the filter core that three layer of one folded body of fiber non-woven filter cloth made owing to having by both sides, both had geometry reliably, to guarantee its permeability and filtering effect, can clean with various cleaning agents again.Therefore, improved service life effectively, and had higher anti-blown sand performance.Be suitable in various natural environments, using.

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model structure.

Fig. 1 be a kind of air filtering core of the utility model vertically partly cut open schematic diagram.

Fig. 2 is the horizontal section schematic diagram of air filtering core shown in Figure 1.

Fig. 3 is the local enlarged diagram of filter cartridge construction.

Fig. 4 be another form air filtering core of the utility model vertically partly cut open schematic diagram.

Fig. 5 is the horizontal section schematic diagram of air filtering core shown in Figure 4.

Referring to figs. 1 through Fig. 3, it has the interior protecting wire net (3) and the outer protecting wire net (7) of tubular the utility model, being provided with between inside and outside protecting wire net by both sides is that metallic screen (5), centre are the folding continuously filter core that constitutes of polypropylene fiber filter cloth (4) layer one, buckle upper end cover (2) in the upper surface of filter core and protecting wire net, buckle bottom end cover (8) in the lower surface of filter core and protecting wire net, the sticking sealing ring (1) that is equipped with on upper end cover (2).

With reference to Fig. 4, Fig. 5, in the structure of the air filtering core of the foregoing description, also can be nested with one deck polypropylene fiber filter cloth (6) again in the folding type filter element outside by above-mentioned wire netting (5), (4) three layers of formation of polypropylene fiber filter cloth, as another kind of form air filtering core, can more effectively improve anti-blown sand like this, improve the effect of filtering effect, and more help cleaning.

The utility model air filtering core is applicable to various automobiles, tractor, engineering truck engine and various internal combustion engine.

Claims

1. washable air filter core, by upper end cover (2), bottom end cover (8), interior protecting wire net (3), outer protecting wire net (7) and place the filter core between inside and outside protecting wire net to form, it is characterized in that said filter core is to be metallic sieve (5), middlely to be formed for (4) three layers of one of fiber non-woven filter cloth are folding continuously by both sides.

2. according to claim a kind of washable air filter core is characterized in that fiber non-woven filter cloth (4) adopts polypropylene fiber to make.
