Abstract
The utility model relates to a non-fabric filter core made by polyurethane end cover and thermosetted, which can be used for the filter cores of the air filter, the oil filter and the gas filter of an internal combustion engine and is composed of an upper end cover (2), a lower cover (1), an inner cylinder (3) and a filter core. The utility model not only has the advantages of a paper filter, namely, high ventilation DEG and smooth surface without dropping hairs, but has the advantages of propene terylene, namely, high oil, water and bursting resistance, high tensile strength, good filtering effect, and long service life. The top and the bottom end covers of the utility model is made by new materials polyamine ester and is thermosetted to save a good deal of metal materials.
Description
The utility model is the filter core that is used for air cleaner for internal combustion engine, oil filter and gasoline filter.
At present, the filter core of the internal-combustion engine of external majority state adopts filter paper.China also begins the filter paper that adopts the paper mill, Shanghai to produce from the sixties.And on the filter core of the air-strainer on red flag board car, Dongfeng brand 140 cars and the Jiefang brand CA141 car, use alternately.On probation showing for many years, homemade filter paper intensity is low, fragility greatly, easily break, be difficult to the maintenance and the maintenance.Therefore working life is short.Recently domestic also have a kind of longer than the paper filter element life-span, tensile strength height, the propylene terylene air filtering core of being convenient to clean, its patent No. is 88209121.2, the applying date is 880729.But the air permeability of propylene terylene air filtering core is relatively poor, easily reduces engine power, because propylene terylene rough surface is fibrous, easily falls hair again, is inhaled into the cylinder of motor.Cause harmful effect, secondly the appearance of propylene terylene air filtering core ash amount only is 50% of a paper filter element, so service cycle is short.In addition, propylene terylene cost height, its price reaches 32 yuan one, and is higher 16 yuan than paper filter element.
The purpose of this utility model provide a kind of can oil resistant, water-fast, and have bursting strength height, air permeability height, hold that the ash amount is big, any surface finish is not fallen hair, cost is low, the life-span is long, the polyamine fat end cap thermoset forming nonwovens filter core of novel structure.
For achieving the above object, the technical solution of the utility model is: filter core is used alternately homemade new material nonwovens and is replaced filter paper, and its air permeability and filtering efficiency all are not less than filter paper, but also have oil resistant, water-fast, bursting strength is high and the advantage of any surface finish.It has not only possessed the advantage of filter paper this new material nonwovens.Be that air permeability height, any surface finish are not fallen hair, and the advantage that possesses the propylene terylene be oil resistant, water-fast, bursting strength is high, tensile strength is high, good filtration effect.Long service life.Upper and lower end cap of the present utility model is to select for use foaming polyamine fat to go up and be folded into a heat cure moulding of corrugated nonwovens at special anchor clamps (separate case application).Replace the end cap of sheet metal punching press with the end cap of this new material polyamine fat heat cure moulding, not only saved metallic material, but also saved the epoxy resin of bonding usefulness.The filter core of domestic production at present all is a combined type, and promptly refill or propylene terylene core all are garden Zhou Fangxiang iron wire clampings, and upper and lower iron sheet lid with punching out uses epoxy bond to form.This combined type filter core complex manufacturing technology, cost height, when packing air-strainer into, upper and lowerly also to add rubber seal.And polyamine fat end cap thermoset forming technology is simple and filter core is an overall structure, thus rigidity might as well, not only save metallic material, epoxy resin but also saved two seal rings when packing air-strainer into.See accompanying drawing 1 because make inside and outside two narrower gardens ring boss (guaranteeing) on the end face of upper and lower end cap by special anchor clamps.
1 structure of the present utility model and embodiment are described in conjunction with the accompanying drawings:
(1) being the lower end cap of filter core, is by foaming polyamine fat heat cure moulding.(2) being the upper end cap of filter core, also is by foaming polyamine fat heat cure moulding.(3) being the inner core of filter core, is the garden tube that is made by chain link fence.(4) be nonwovens.
With nonwovens (4) by the waveform that is folded into shown in the accompanying drawing 1, be rolled into the garden tubular, be enclosed within the periphery of inner core (3), (4) that will package then and (3) are placed in the special anchor clamps (separate case application) of coating foaming polyamine fat, the moulding of locating, tighten up, be heating and curing.Promptly make whole polyamine fat end cap thermoset forming nonwovens filter core.
When the utility model was loaded on liberation CA141 automobile, the internal diameter of upper and lower end cap was ∮ 164mm, and external diameter is ∮ 270mm, and the distance between the upper and lower end cap is 120mm.When being contained on 140 cars of Dongfeng brand, the internal diameter of upper and lower end cap is ∮ 164mm, external diameter is ∮ 240mm, between end cap apart from 110mm.
The utility model can be used for the filter core of air cleaner for internal combustion engine, oil filter and gasoline filter.This filter core have oil resistant, water-fast, tensile strength is high, hold that the ash amount is big, air permeability is high, any surface finish is not fallen hair, long service life, low, the advantages of simple structure and simple of cost.
Claims (2)
1, a kind of polyamine fat end cap thermoset forming nonwovens filter core, it is made of loam cake (2), lower cover (1), inner core (3), filter core (4), it is characterized in that: filter core is that nonwovens (4) is folded into waveform, be rolled into the garden tubular, the be enclosed within inner core periphery of (3), again with foaming polyamine fat be heating and curing moulding upper end cap (2) and lower end cap (1).
2,, it is characterized in that making on the end face of said loam cake (2) and lower cover (1) inside and outside two narrower gardens ring boss according to the described polyamine fat of claim 1 end cap thermoset forming nonwovens filter core.
