Abstract
The invention discloses a filter core of air filter which is purposed to supply an air filter which can be repeatedly used. The inventive filter core is formed by a metallic filter network, upper and lower end covers, and inner and outer sealing rings fixed on the lower end cover. It is characterized in that: the filter element of filter core is made from steel fiber and covered by metallic filter network; said stainless fiber is woven from 0.4-0.7mm stainless steel wires. The invention replaces the traditional paper or non-woven cloth with stainless steel fiber to avoid polluting environment and save material.
Description
Technical field
The filter core of a kind of air-strainer of the present invention relates to fuel oil machinery and car engine air admittance filtrating equipment.
Background technique
It is filter material that existing Vehicular air filtering core device mainly adopts micropore filter paper, and its working life is short, and filter paper in use breaks easily, and described filter paper can not clean and use repeatedly, has caused waste.And filter paper itself is to be the raw material manufacturing with cotton, wood pulp, will consume a large amount of timber in the manufacture process, and can produce waste water.
Summary of the invention
The purpose of the filter core of a kind of air-strainer of the present invention is to propose a kind of air filtering core device that can repeated washing uses, the filter core of a kind of air-strainer of the present invention is by metal screen, end cap and the interior exterior seal ring that is fixed on the lower end cap of inside and outside filter core constitute up and down, it is characterized in that: filter element filtering of the present invention partly adopts the Steel Fibre material, is formed by the metal screen parcel; Described Stainless Steel Fibre is by 0.4 ~ 0.7 millimeter Stainless Steel Wire is made into the cloth shape; The present invention substitutes traditional paper or nonwovens by stainless steel fiber material and has avoided pollution and disposable waste to environment.
Description of drawings
Fig. 1 is the outer core cross-sectional view of the filter core of a kind of air-strainer of the present invention.
Fig. 2 is the filter core inner core cross-sectional view of a kind of air-strainer of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, the inner core of the filter core of a kind of air-strainer of the present invention is by the fixing one deck Steel Fibre filtering material 3 of wire netting 1,4 and filter core loam cake 2, filter core lower cover 5, and density is for well more than 450.The outer core of the filter core of a kind of air-strainer of the present invention can adopt two-layer Steel Fibre filtration.Both outer coated metal filter screen 10; Interlayer is two-layer Stainless Steel Fibre layer 8,9; The inner end of core covers layer of metal filter screen 7 again outside described; Fixing by filter core loam cake 6 and filter core lower cover 12.By test, outer field Steel Fibre density is at 230～260 orders; Internal layer Steel Fibre 360～400 order effects are better, on military vehicle, enter motor for fear of toxic gas, the present invention is provided with a gas defence purifying layer 11 in the interlayer of core outside, described gas defence purifying layer is to be coated on the metal screen after high temperature resistant environment-protective glue and the calcium carbonate mediation, and the mass ratio of described high temperature resistant environment-protective glue and calcium carbonate is 1: 8.Steel Fibre material of the present invention is that the Stainless Steel Fibre effect is best.
