Abstract
The utility model relates to a kind of air filter, particularly relates to a kind of integral hermetic air filtering core.Its structure is: connected by PU glue between adjacent folds filter paper pleat, and connecting side outer setting by PU glue has PU glue material end cap, is provided with steel wire bottom filter core paper.Air filtering core of the present utility model eliminates PUR, very suitable for mechanization processing, improve production efficiency, adopt the sealing of PU glue integration, also complete the sealing at filter core paper two in the operation injecting PU simultaneously, the sealing of product is fully protected, filter paper increases lattice steel expanded metals, and filer element strength increases, when flow is large, filter core can not produce distortion, extends the service life of filter core.
Description
Technical field
The utility model relates to a kind of air filter, particularly relates to a kind of integral hermetic air filtering core.
Background technology
Containing various foreign-matter contamination in air, burning can be affected during gasoline combustion in gasoline engine, in air, aphlogistic hard impurity also can damage engine, first purifies air so must arrange air cleaner before air enters combustion chamber, is filtered by foreign-matter contamination and removes.
The edge, filter paper both sides of the multilayer folding of filtering element for air filter in the market need pour into PUR adhesion, and the folding number of plies is on demand inserted in mould and injected PU glue and be shaped into product.This kind of filter core paper, because folding is apart from little, at two of filter paper perfusion PUR, will be received ripple and tight difficulty, easily causes the leakage of two head edges during mechanization production while folding between the pleat of folded filter paper.Once leak, just lose the function of filter element filtering, easily cause the infringement of engine.In addition, intensity difference after mould molding inserted by filter paper, and when mass flow air enters, the easy flexural deformation of filter core, can strengthen intake resistance like this, thus increases fuel consumption.
Utility model content
According to of the present utility model for solving the problems of the technologies described above, the integral hermetic air filtering core sealing that the utility model provides is strong, fastness can increase the service life well.
For achieving the above object, the technical solution of the utility model is as follows: a kind of integral hermetic air filtering core, comprise a kind of integral hermetic air filtering core, comprise folded filter paper, it is characterized in that: adjacent folds filter paper pleat end is connected by PU glue, folded filter paper end is provided with the PU glue material end cap bonded with end; Steel wire is provided with bottom folded filter paper.
As preferably, described folded filter paper cross section is that sawtooth is wavy.
As preferably, described steel wire grid is rhombus.
By technique scheme, the beneficial effect of a kind of integral hermetic air filtering core that the utility model provides is: the utility model, owing to eliminating PUR, adds man-hour at folded filter paper, and very suitable for mechanization processing, improves production efficiency.Have employed the sealing of PU integration, also complete the sealing at filter core paper two in the operation injecting PU simultaneously, the sealing of product is fully protected.
After having added lattice steel expanded metals, filer element strength increases, and when flow is large, filter core can not produce distortion, guarantees that operating mode is normal.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is a kind of integral hermetic air filtering core construction schematic diagram disclosed in the utility model embodiment;
Fig. 2 is a kind of integral hermetic air filtering core cross-sectional view disclosed in this use new embodiment
Corresponding component title in figure represented by numeral:
1-folded filter paper pleat 2-steel wire 3-PU glue material end cap
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
According to Fig. 1 and Fig. 2, the utility model provides a kind of integral hermetic air filtering core, comprises folded filter paper, and the cross section of folded filter paper is that sawtooth is wavy, adjacent folds filter paper pleat 1 end is connected by PU glue, and folded filter paper end is provided with the PU glue material end cap 3 bonded with end; Be provided with steel wire 2 bottom folded filter paper, the grid of steel wire 2 is rhombus.
The utility model makes production simple and convenient, and production efficiency increases substantially.Add man-hour at folded filter paper, protect operation owing to eliminating heat injection melten gel on filter paper, also complete the sealing at filter core paper two in the operation injecting PU glue simultaneously, ensure that the production that ripple is received in paper folding is carried out in mechanization fast.Owing to have employed the sealing of PU integration, when original operation injects PU, apply suitable fixture, ensure that the reliability that filter core two seals, save one heat injection melten gel operation.
Add lattice steel expanded metals bottom filter paper after, the intensity of filter core increases greatly, even if under large discharge, also can not occur because of filter paper and roll over, and increases resistance and causes loss fuel, like this can prolonging service life of filter elements.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
