Abstract

A high-polymer water-proof non-woven fabric air-filter filter core relates to a filter core of an air filter and resolves the problem that existing filter cores are low in ventilating quantity and poor in water-proof effect. The lower end of a metal grid annular framework is fixedly arranged on a metal lower end cover, a center hole is arranged on polyurethane (PU) polystyrene foam or a metal upper end cover, the upper end of the metal grid annular framework is fixedly arranged on the PU polystyrene foam or the metal upper end cover, and the center line of the metal grid annular framework coincides with the axis of the center hole on the PU polystyrene foam or the center hole of the metal upper end cover. A polyethylene terephthalate (PET) terylene non-woven fabric body is an annular body, the inner surface of the PET terylene non-woven fabric body is fixedly connected with the outer surface of the metal grid annular framework, the upper end of the PET terylene non-woven fabric body is fixedly arranged on the PU polystyrene foam or the metal upper end cover, and the lower end of the PET terylene non-woven fabric body is fixedly arranged on the metal lower end cover. The high-polymer water-proof non-woven fabric air-filter filter core is applicable for car air filters.

Description

Macromolecule water proof nonwoven cloth air cleaner cartridge

Technical field

The utility model relates to a kind of filter element, is specifically related to a kind of macromolecule water proof nonwoven cloth air cleaner cartridge.

Background technique

In the process of engine running, need combustion air, and contain sand usually in the air, foreign matters such as dust and steam, the problem that causes therefrom:, after foreign matter gets into the cylinder body of motor, cause the wearing and tearing of cylinder body easily; Two, in foreign matter entering engine motor oil, then possibly 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 getting into 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; Second kind of filter core of research and development 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, is that the Air permenbility of the filter core of filtering material is merely 260m with cotton pulp filter paper ³/ m ²/ s is that the Air permenbility of the filter core of filtering material is merely 360m 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 the utility model be for solve Air permenbility that existing filter core exists low with the waterproofing effect difference problem, and then a kind of macromolecule water proof nonwoven cloth air cleaner cartridge is provided.

The technological scheme of the utility model is: macromolecule water proof nonwoven cloth air cleaner cartridge comprises PU foamed glue or metal upper end lid, PET terylene non-woven fabric body, metal grill ring skeleton and metal lower end cap; The lower end of metal grill ring skeleton is fixedly mounted on the metal lower end cap; PU foamed glue or metal upper end cover and have center hole; The upper end of metal grill ring skeleton is fixedly mounted on the PU foamed glue or metal upper end covers; And the center line of metal grill ring skeleton overlaps with the center hole axis that PU foamed glue or metal upper end cover; PET terylene non-woven fabric body is an annular body; The internal surface of PET terylene non-woven fabric body is fixedly connected with the outer surface of metal grill ring skeleton, and the upper end of PET terylene non-woven fabric body is fixedly mounted on the PU foamed glue or metal upper end covers, and the lower end of PET terylene non-woven fabric body is fixedly mounted on the metal lower end cap.

The utility model compared with prior art has following effect: the utility model combines through adopting PU foamed glue or metal upper end lid, PET terylene non-woven fabric body, metal grill ring skeleton and metal lower end cap, has improved the fastness of air cleaner cartridge; Through adopting PET terylene non-woven fabric body to improve Air permenbility and waterproofing effect, Air permenbility reaches 580m 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:

Embodiment

Embodiment one: combine Fig. 1 to Fig. 3 that this mode of execution is described; The macromolecule water proof nonwoven cloth air cleaner cartridge of this mode of execution comprises PU foamed glue or metal upper end lid 1, PET terylene non-woven fabric body 2, metal grill ring skeleton 3 and metal lower end cap 4; The lower end of metal grill ring skeleton 3 is fixedly mounted on the metal lower end cap 4; Have center hole 1-1 on PU foamed glue or the metal upper end lid 1; The upper end of metal grill ring skeleton 3 is fixedly mounted on PU foamed glue or the metal upper end lid 1; And the center hole 1-1 dead in line on the center line of metal grill ring skeleton 3 and PU foamed glue or the metal upper end lid 1, PET terylene non-woven fabric body 2 is an annular body, the internal surface of PET terylene non-woven fabric body 2 is fixedly connected with the outer surface of metal grill ring skeleton 3; The upper end of PET terylene non-woven fabric body 2 is fixedly mounted on PU foamed glue or the metal upper end lid 1, and the lower end of PET terylene non-woven fabric body 2 is fixedly mounted on the metal lower end cap 4.

The English of PET is called Polythylene terephthalate, and Chinese implication is a PETG;

The English of PU is called Polyurethane, and Chinese abbreviates polyurethane as, and Chinese full name is a polyurethane.

Embodiment two: combine Fig. 1 and Fig. 2 that this mode of execution is described, the PET terylene non-woven fabric body 2 of this mode of execution surrounds by the PET terylene non-woven fabric is along the circumferential direction folding, and broken line is parallel with the central axis of metal grill ring skeleton 3.So be provided with, not only increased filter area, improved pollutant holding capability, and avoided the appearance of body collapse-deformation problem.Other composition is identical with embodiment one with annexation.
