The filter element disclosed by the utility model is suitable for being used in an automobile air filter.

Description

Polyurethane high molecule nonwovens washing filter element

Technical field

The utility model relates to a kind of washing filter element, is specifically related to a kind of polyurethane high molecule nonwovens washing filter element.

Background technique

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 motor, 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 motor; 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 motor car engine, air must be through filtering, so that remove foreign matter before entering motor.Therefore, dispose air-strainer before the motor car 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 of filter core is metal end and metallic support grid structure, and what it adopted is that cotton pulp or wood pulp filter paper are the filter core of filtering material; Yan Fa second kind of filter core then, this filter core is a PU foamed glue end cap, and still adopting cotton pulp or wood pulp filter paper is the filter core of filtering material, and the drawback of above-mentioned filter core is that Air permenbility is low, and the Air permenbility that with cotton pulp filter paper is the filter core of filtering material only is 360m ³/ m ²/ s is that the Air permenbility of the filter core of filtering material only is 380m with wood pulp filter paper ³/ m ²/ s, the non-constant of waterproofing effect, when surface of filter medium had dust, touching malaria will stop up the inlet hole large size of filter material, caused the engine intake and exhaust system can't eupnea.

The model utility content

The purpose of this utility model be for solve the low and waterproofing effect difference of Air permenbility that existing filter core exists problem, and then provide a kind of polyurethane high molecule nonwovens washing filter element.

The technical solution of the utility model is: polyurethane high molecule nonwovens washing filter element is by PU foamed glue upper end cap, PET terylene non-woven fabric body, PP injection moulding grid ring skeleton and PU foamed glue lower end cap are formed, have center hole on the described PU foamed glue upper end cap, the upper end of described PP injection moulding grid ring skeleton is fixedly mounted on the PU foamed glue upper end cap, and it is corresponding with the center hole on the PU foamed glue upper end cap, the lower end of described PP injection moulding grid ring skeleton is fixedly mounted on the PU foamed glue lower end cap, described PET terylene non-woven fabric body is an annular body, the internal surface of PET terylene non-woven fabric body is fixedlyed connected with the outer surface of PP injection moulding grid ring skeleton, the upper end of PET terylene non-woven fabric body is fixedly mounted on the PU foamed glue upper end cap, and the lower end of PET terylene non-woven fabric body is fixedly mounted on the PU foamed glue lower end cap.

The utility model compared with prior art has following effect: the utility model combines by adopting PU foamed glue upper end cap, PET terylene non-woven fabric body, PP injection moulding grid ring skeleton and PU foamed glue lower end cap, has improved the fastness of air cleaner cartridge; By adopting PET terylene non-woven fabric body to improve Air permenbility and waterproofing effect, Air permenbility reaches 860m ³/ m ²/ s, the unlimited number of times of PET terylene non-woven fabric body cleans, and dries and can continue to use, and filtering effect is constant; 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.Test parameters and test result such as the table 1 of the utility model behind overtesting:
