Abstract
The utility model discloses an air filter material as well as a filter element and a filter element body made of the air filter material, wherein the air filter material is suitable for filtering air in an electronic cabin of a civil airline and belongs to the technical field of filter equipment. The air filter element comprises a filter element body and end covers respectively arranged at two ends of the filter element body, wherein the filter element body comprises an inner framework and an outer framework which are concentrically nested together and a filter layer fixed between the inner framework and the outer framework; the filter layer is made of a non-woven filter material; and holes of the non-woven filter material are gradually reduced along the air flowing direction. The filter material disclosed by the utility model is the non-woven filter material with the holes gradually reduced along the air flow direction, the densities of the filter layers of the filter element body and the filter element which are made of the filter material are gradually transitioned from small to large; when the air filter element is used to filter air, the holes with different sizes are used for blocking dust particles with corresponding sizes, so that the condition that the filter effect is affected if the large-particle dust is accumulated on an interface where the density is suddenly changed is avoided, and furthermore, the low resistance is reduced and the filtering effect is ensured.
Description
Technical field
The utility model relates to a kind of air filtering material and uses filter core and the filter body of this filter material, is particularly useful for filtering the air in the airline carriers of passengers electronic compartment, belongs to the filter plant technical field.
Background technology
At aviation field, air enters into the airline carriers of passengers electronic compartment by ventilating system, aviation electronics element in electronic compartment need to could work in the environment in dried and clean, therefore air filtering core is installed usually in ventilating system and will be entered into dust and the moisture filtering in the passenger plane electronic compartment, this air filtering core needs dedusting simultaneously and dehumidifying.The filter course of traditional air filtering core is generally made by cotton pulp filter paper, and because this filter course moisture-proof is poor, under high humidity environment, the dust removal and filtration layer easily forms filter cake, and flow resistance is high, and shortened the service life of filter core.The structure of the air filtering core used in existing airline carriers of passengers electronic compartment as shown in Figure 1 to Figure 3, it comprise with one heart sheathed inner frame 1 and outer skeleton 2 and be fixed on inner frame 1 and outer skeleton 2 between filter course, by two-layer density, different nonwoven cloth materials combines this filter course, the density density less, internal layer nonwoven 32 of outer nonwoven 31 is larger, as shown in Figure 3, the interface of every layer of nonwoven adopts the mode of linear slit to be docking together, this method of making strengthened the workman labour intensity, make complex manufacturing.Because moisture-proof and the resistance to fracture of nonwoven are all very strong, therefore, the filter course of this filter core is not easy to form filter cake.But; the density of this filter course increases from outside to inside suddenly, and the bulky grain dust is easy to be deposited on interface sudden change place of two-layer nonwoven, causes the flow resistance increase of filter core; be easy to make filter core to block and scrap, if change, may cause not in time aircraft report to the police or make a return voyage.
Summary of the invention
The purpose of this utility model is to provide a kind of air filtering material with low flow resistance performance while filtered water and dust, and the utility model also provides a kind of filter core and filter body that uses this filter material simultaneously.
For achieving the above object, air filtering core of the present utility model adopts following technical scheme: a kind of air filtering core, the end cap that it comprises filter body and is separately positioned on the filter body two ends, filter body comprise the inside and outside inner frame be set-located with one heart and outer skeleton and be fixed on inner frame and outer skeleton between filter course, filter course is made by the nonwoven filter material, and the hole of described nonwoven filter material reduces gradually by the direction of Air Flow.
Described filter course is wound around two circles and forms on inner frame by the nonwoven filter material.
Air filter core body of the present utility model adopts following technical scheme: a kind of air filter core body, it comprise the inside and outside inner frame be set-located with one heart and outer skeleton and be fixed on inner frame and outer skeleton between filter course, filter course is made by the nonwoven filter material, and the hole of described nonwoven filter material reduces gradually by the direction of Air Flow.
Described filter course is wound around two circles and forms on inner frame by the nonwoven filter material.
Air filtering material of the present utility model adopts following technical scheme: a kind of air filtering material, and it is the nonwoven filter material, the hole of described nonwoven filter material reduces gradually by the direction of Air Flow.
Filter material of the present utility model is the nonwoven filter material reduced gradually by air-flow direction by a kind of hole; use the filter body of this filter material and the filter course density of filter core to be transitioned into gradually densification by loosening; when filtered air; the hole of different sizes is tackled the dust of corresponding size particles; avoided density abrupt interface place to affect filter effect because assembling the bulky grain dust; thereby the reduction flow resistance, guarantee filter effect.
Further, filter material directly is wound around the form of two circles on inner frame, does not need to adopt the mode of linear slit to be docking together, and having solved filter material of the prior art need to be along the problem axially be sewed together of filter core, thereby simplified production technology, reduced workman's labour intensity; And the nonwoven filter material of internal layer can further be tackled dust and moisture, further improves filter efficiency.

The specific embodiment
A kind of embodiment of air filtering core of the present utility model as shown in Figure 4 and Figure 5, the air filtering core of the present embodiment comprises filter body and is separately positioned on the end cap at filter body two ends, filter body comprise the inside and outside inner frame be set-located with one heart 1 and outer skeleton 2 and be fixed on inner frame 1 and outer skeleton 2 between filter course 3, filter course 3 is wound around two circles and forms on inner frame by the nonwoven filter material, the hole of nonwoven filter material reduces gradually by the direction of Air Flow.
As shown in Figure 5, in the present embodiment, the density of filter material is transitioned into densification gradually by loosening, the nonwoven filter material that this hole reduces gradually increases the adsorbance of filter course, when filtered air, the hole of different sizes is tackled the dust of corresponding size particles, avoided density abrupt interface place to affect filter effect because assembling the bulky grain dust, thereby reduced flow resistance, guaranteed that filter effect has improved dust containing capacity; And the nonwoven filter material is wound around the forms of two circles on inner frame, do not need the mode of adopt sewing up to make to be docking together without filter material, thereby simplified production technology, reduced workman's labour intensity.
In other embodiment of the present utility model, filter course also can be wound around by the nonwoven filter material three circles on inner frame or multilayer forms; Filter course also can be wound around by the nonwoven filter material circle and form on inner frame, now, and need to axially the filter material two ends be sewed together along filter core.
The embodiment of the utility model air filter core body is identical with the filter body structure in the embodiment of the utility model air filtering core, repeats no more herein.
The embodiment of the utility model air filtering material as shown in Figure 5, the nonwoven filter material that it reduces by the direction of Air Flow gradually for hole.
