Abstract
The utility model belongs to the technical field of air filtration, disclosing an air filter, which is technologically characterized by comprising an internal silk net and an external silk net, wherein a folding filter paper layer is arranged between the internal silk net and the external silk net, and a non-woven filter layer is arranged on the outer side of the filter paper layer. The air filter provided by the utility model increases the filtering rate of an original single filter paper layer by nearly one time through arranging the non-woven filter layer on the outer side of the filter paper layer to form the double-layer filtering, and has excellent filtering effect. Furthermore, the non-woven has the characteristics of large factor of porosity, small pore space and zigzag aperture, large ventilation property, strong dust storage capability, easy cleaning, excellent bursting resistance intensity and waterproof performance, which facilitates to greatly prolong the service life of the air filter.
Description
Technical field
The utility model belongs to the air filtration technical field, relates in particular to a kind of air filter.
Background technology
The air filter of current use comprises nexine silk screen and outer silk screen, is provided with folding filter paper layer between nexine silk screen and outer silk screen.This filter paper layer in use is easy to be filled up by particle suspensions, thereby reduces filter effect, reduction of service life.
The utility model content
Problem to be solved in the utility model just provides the air filter of a kind of good filtration effect, long service life.
For addressing the above problem, the technical solution adopted in the utility model is: comprise nexine silk screen and outer silk screen, be provided with folding filter paper layer between nexine silk screen and outer silk screen, the arranged outside of described filter paper layer has the nonwoven filter course.
Its additional technical feature is: described nonwoven filter course is folded with.
Air filter provided by the utility model compared with prior art, the arranged outside of filter paper layer has the nonwoven filter course, becomes double medium filtration, has improved nearly one times, good filtration effect than the degree of filtration of original individual layer filter paper layer.And nonwoven has the characteristics of big and small-bore, the crack complications of porosity, and Air permenbility is big, and it is strong, easy to clean to store up grey amount ability, and anti-bursting intensity and water resistance are all very good, make prolong greatly the service life of this air filter.
Description of drawings
Accompanying drawing is the structural representation of the utility model air filter.
The specific embodiment
Be described in further details below in conjunction with the structure of accompanying drawing the utility model air filter.
As shown in the figure, the utility model air filter comprises nexine silk screen 1 and outer silk screen 2, and 2 on nexine silk screen 1 and outer silk screen are provided with folding filter paper layer 3, and the arranged outside of filter paper layer 3 has folding nonwoven filter course 4.
The air filter that the utility model provides change original individual layer filter paper layer into filter paper layer 3 and nonwoven filter course 4 bilayers, but filter thickness is constant.During use, its filter process is finished by filter paper layer 3 and nonwoven filter course 4 bilayers, has improved nearly one times, good filtration effect than the degree of filtration of original individual layer filter paper layer.And nonwoven has the characteristics of big and small-bore, the crack complications of porosity, and Air permenbility is big, and it is strong, easy to clean to store up grey amount ability, and anti-bursting intensity and water resistance are all very good, make prolong greatly the service life of this air filter.
Claims (2)
