Abstract
Disclosed is an air filter which comprises an upper cover, a lower cover, an inner layer silk net and an outer layer silk net. A folded filter paper layer is arranged between the inner layer silk net and the outer layer silk net. The air filter is characterized in that a needling woolen filter cloth filtering layer arranged in folded arrangement is mounted between the inner side of the filter paper layer and the inner layer silk net; a sealing ring is arranged on the upper portion of the upper cover; the width of the folded filter paper layer arranged in folded arrangement ranges from 3 centimeters to 4 centimeters; and the width of the folded needling woolen filter cloth filter layer in folded arrangement ranges from 0.5 centimeters to 2 centimeters. Compared with the prior art, the air filter adopts the needling woolen filter cloth filtering layer arranged on the inner side of the filter paper layer to be multi-layer filter, thereby improving filtering effect.
Description
Technical field
The utility model relates to a kind of air filter, belongs to the technical field of air filtration aspect.
Background technology
At present, known air filter 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.
Summary of the invention
At the deficiency that above-mentioned technical problem exists, the purpose of this utility model provides a kind of air filter.
The technical solution of the utility model is as follows:
A kind of air filter comprises loam cake and lower cover, nexine silk screen and outer silk screen, be provided with folding filter paper layer between nexine silk screen and outer silk screen, it is characterized in that, between the inboard and nexine silk screen of described filter paper layer, be provided with the acupuncture suede filter cloth filter course that is folded with.Top at described loam cake is provided with sealing ring.
Described acupuncture suede filter cloth filter course is a kind of eedle-punched non-wovens that forms with the needing machine puncture or is Nomex.
The also available nonwoven of described acupuncture suede filter cloth filter course replaces.
The folding back width of the described filter paper layer that is folded with is 3 to 4 centimeters.
The folding back of the described acupuncture suede filter cloth filter course that is folded with width is 0.5 to 2 centimeter.
The folding back width of the described filter paper layer that is folded with is 3.5 centimeters.
The folding back of the described acupuncture suede filter cloth filter course that is folded with width is 1 centimeter.
The utility model is compared with technique known, because of the inboard in filter paper layer is provided with acupuncture suede filter cloth filter course, becomes multiple filtration, thereby has improved the filtering effect.
Description of drawings
Fig. 1 is a sectional structure schematic diagram of the present utility model.
Among the figure: 1 nexine silk screen, 2 outer silk screens, 3 filter paper layer, 4 acupuncture suede filter cloth filter courses, 5 sealing rings.
The specific embodiment
As shown in Figure 1, comprise loam cake and lower cover, nexine silk screen 1, outer silk screen 2, top at described loam cake is provided with sealing ring, be provided with folding filter paper layer 3 at nexine silk screen 1 and 2 on outer silk screen, be provided with folding acupuncture suede filter cloth filter course 4 in the inboard of filter paper layer 3, be provided with sealing ring 5 on the top of described loam cake.
The air filter that the utility model provides change original individual layer filter paper layer into filter paper layer 3 and acupuncture suede filter cloth filter course 4 bilayers, but filter thickness is constant.During use, its filter process is finished by filter paper layer 3 and acupuncture suede filter cloth filter course 4 multilayers, and described acupuncture suede filter cloth filter course is a kind of eedle-punched non-wovens that forms with the needing machine puncture or is Nomex that the also available nonwoven of described acupuncture suede filter cloth filter course replaces.The folding back width of the filter paper layer that it is folded with is 3 to 4 centimeters, and the folding back of the acupuncture suede filter cloth filter course that it is folded with width is 0.5 to 2 centimeter.
The utility model is compared with known technology, because the inboard in filter paper layer is provided with acupuncture suede filter-cloth filtering layer, becomes multiple filtration, thereby has improved the filtering effect.
