Abstract

The utility model relates to a PET dacron non-woven fabric air cleaner cartridge, relating to an air cleaner cartridge, and solving the problems that the cartridge made of an PU end cover and paper fibre and the cartridge made of a metal end cover and paper fibre have deficiencies of low recovery rate, small ventilation amount and poor waterproof effect. In the utility model, the upper end of a PET injection-molding gridding annular skeleton is fixedly arranged on a PET injection-molding upper end cover and corresponds to the central hole of the PET injection-molding upper end cover, and the lower end thereof is fixedly arranged on a PET injection-molding lower end cover; a PET dacron non-woven fabric body is of an annular body; the inner surface of the PET dacron non-woven fabric body is fixedly connected with the outer surface of the PET injection-molding gridding annular skeleton; and the upper end of the PET dacron non-woven fabric body is fixedly arranged on the PET injection-molding upper end cover, and the lower end thereof is fixedly arranged on the PET injection-molding lower end cover. The PET dacron non-woven fabric air cleaner cartridge is applicable to automobile air cleaners.

Description

PET terylene non-woven fabric air filter element

Technical field

The utility model relates to a kind of air cleaner cartridge, is specifically related to a kind of PET terylene non-woven fabric air filter element.

Background technology

In the process of engine running, need combustion air, and contain sand usually in the air, foreign matter such as dust and steam, the problem of Yin Faing therefrom: one, after foreign matter enters the cylinder body of engine, cause the wearing and tearing of cylinder body easily; Two, enter in the engine motor oil when foreign matter, then may bring the heavy wear between the whole friction pair of engine; If the volume of three foreign matters is bigger, then might stop up the engine air throttle valve body, cause valve body work to have some setbacks.Therefore, in order to guarantee the normal operation of automobile engine, air must be through filtering, so that remove foreign matter before entering engine.Therefore, dispose air filter before the automobile engine usually, it generally includes housing, and is arranged on the filter core that is used to filter foreign matter in the housing.Filter core of the prior art: first kind is the irony filter core, and it filters body is the iron net, poor filtration effect; Then researched and developed second kind of filter core, this filter core is the filter core that the PU material is made, and it filters body is papery, because the PU material has difficult characteristic of decomposing, therefore the recycling rate is low, and adopts the filtration body waterproof effect difference and the Air permenbility of papery little, and its Air permenbility only is 580m ³/ m ²/ s.

Summary of the invention

The purpose of this utility model is that the recycling rate that filter core that filter core that existing P U material end cap and paper fiber make and metal end and paper fiber make exists is low, Air permenbility is little and the problem of waterproof effect difference in order to solve, and then a kind of PET terylene non-woven fabric air filter element is provided.

The technical solution of the utility model is: PET terylene non-woven fabric air filter element is by PET injection moulding upper end cover, PET terylene non-woven fabric body, PET injection moulding grid ring skeleton and PET injection moulding bottom end cover are formed, have centre bore on the described PET injection moulding upper end cover, the upper end of described PET injection moulding grid ring skeleton is fixedly mounted on the PET injection moulding upper end cover, and it is corresponding with the centre bore on the PET injection moulding upper end cover, the lower end of described PET injection moulding grid ring skeleton is fixedly mounted on the PET injection moulding bottom end cover, described PET terylene non-woven fabric body is an annular body, the inner surface of PET terylene non-woven fabric body is fixedlyed connected with the outer surface of PET injection moulding grid ring skeleton, the upper end of PET terylene non-woven fabric body is fixedly mounted on the PET injection moulding upper end cover, and the lower end of PET terylene non-woven fabric body is fixedly mounted on the PET injection moulding bottom end cover.

The utility model compared with prior art has following effect: the utility model has improved the recycling rate of air cleaner cartridge by adopting PET injection moulding upper end cover, PET terylene non-woven fabric body, PET injection moulding grid ring skeleton and PET injection moulding bottom end cover, and its recovery utilization rate can reach 100%; By adopting PET terylene non-woven fabric body to improve Air permenbility and waterproof effect, Air permenbility reaches 860 m ³/ m ²/ s after the immersion of PET terylene non-woven fabric body, dries and can continue to use, and filter effect inconvenience; The utility model also has long service life, filtering is effective, filtering efficiency is high and stores up the strong advantage of grey ability simultaneously, is applicable in the air filter of automobile, steamer, train, aircraft, motorcycle, tractor etc.Test parameters and result of the test such as the table 1 of the utility model behind overtesting:
