Abstract
The utility model discloses a filter element of an efficient air filter with filter paper unlikely to loose. The filter element comprises a cylindrical filter screen and a holder located at the inner ring of the cylindrical filter screen, wherein filter paper is sandwiched between the cylindrical filter screen and the holder, a fixing line winded on the outer ring of the filter paper is adhered to the outer ring of the filter paper, a rough filtrating layer made from non-woven fabrics is arranged on the outer ring of the cylindrical filter screen, the rough filtrating layer, the cylindrical filter screen, the filter paper and the holder form a cylinder body together, and an upper filter element cover provided with a sealing ring and a lower filter element cover provided with a sealing ring are respectively installed at the two ends of the cylinder body. The filter element disclosed by the utility model has a simple and reasonable structure; the rough filtrating layer is arranged at the outer ring of the filter screen, thereby effectively filtering large granular dust impurities and reducing the dust adsorbing capacity of the filter paper; and the fixing line is arranged at the outer circle of the filter paper, thereby preventing the filter paper from loosing after long-time use, prolonging the service life, effectively ensuring the filtering efficiency of the air filter and guaranteeing safe operation of such apparatuses as pneumatic machines and internal combustion engines.
Description
Technical field
The utility model relates to the air filter that uses in the fields such as a kind of pneumatic machinery, diesel machine, is specially a kind of filter paper and is difficult for loose high efficiency air filter filter core.
Background technology
Air filter is mainly used in fields such as pneumatic machinery, diesel machine, and effect is the air that cleaning is provided for these plant equipment, the probability that increases abrasion in case these plant equipment suck the air that has impurity particle at work and damage.The chief component of air filter is filter core and casing, and wherein filter core is main filtration fraction, bearing the filtration work of gas, and casing is the external structure that necessary protection is provided for filter core.And the filter screen of existing air cleaner cartridge can not leach the dust impurity of larger particles effectively, make filter paper impaired easily, long-time its filter paper of back that uses is loose easily, make that filtering efficiency descends behind the whole cleaner long time continuous working, service life is shorter, can not well satisfy instructions for use.
The utility model content
The purpose of this utility model provides a kind of filter paper and is difficult for loose high efficiency air filter filter core, can not leach the dust impurity of larger particles effectively with the filter screen that solves air cleaner cartridge traditional in the prior art, make filter paper impaired easily, long-time its filter paper of back that uses is loose easily, make that filtering efficiency descends behind the whole cleaner long time continuous working, service life is shorter, can not finely satisfy the problem of instructions for use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of filter paper is difficult for loose high efficiency air filter filter core, it is characterized in that: include tubular filter screen and the retainer that is positioned at tubular filter screen inner ring, accompany filter paper between described tubular filter screen and the retainer, the sticking glutinous static line that is wound on the filter paper outer ring that has in described filter paper outer ring, described tubular filter screen outer ring is provided with the coarse filtration layer that nonwoven is made, the common formation of described coarse filtration layer, tubular filter screen, filter paper and retainer one cylindrical shell, described cylindrical shell two ends are separately installed with filter core loam cake and the filter core lower cover that has sealing ring.
Described a kind of filter paper is difficult for loose high efficiency air filter filter core, it is characterized in that: adopt glue bond to fix between described filter core loam cake, filter core lower cover and the cylindrical shell.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, adopts the design that the coarse filtration layer is set in the filter screen outer ring, can leach the dust impurity of larger particles effectively, has reduced the dust adsorbance of filter paper; Employing arranges the design of static line in the filter paper outer ring, be difficult for loosely after making that filter paper is long-time and using, and has prolonged service life, has guaranteed the filtering efficiency of air filter effectively, has guaranteed the safe operation of equipment such as pneumatic machinery, diesel machine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of filter paper is difficult for loose high efficiency air filter filter core, include tubular filter screen 1 and the retainer 2 that is positioned at tubular filter screen 1 inner ring, accompany filter paper 3 between tubular filter screen 1 and the retainer 2, the sticking glutinous static line 4 that is wound on filter paper 3 outer rings that has in filter paper 3 outer rings, tubular filter screen 1 outer ring is provided with the coarse filtration layer 5 that nonwoven is made, coarse filtration layer 5, tubular filter screen 1, filter paper 3 and retainer 2 common formation one cylindrical shells, the cylindrical shell two ends are separately installed with filter core loam cake 6 and the filter core lower cover 7 that has sealing ring.
Adopt glue bond to fix between filter core loam cake 6, filter core lower cover 7 and the cylindrical shell.
Claims (2)
