Abstract
An oil filter comprises a casing, a first filter unit, a second filter unit and an alkaline filter unit. The first filter unit and the second filter unit are arranged in the casing, the alkaline filter unit is surrounded by the second filter unit which is surrounded by the first filter unit. The oil filter has the advantages of being capable of removing acid substances in oil.
Description
Technical field
The present invention relates to a kind of oil filter, especially a kind of oil filter that contains alkali matter.
Background technique
Oil filter is the device for purifying engine machine oil, and it can remove metal granule, colloid substance and other impurity in the machine oil.Traditional oil filter generally adopts the impurity particle in the filter membrane filtering machine oil, reduces impurity particle to the wearing and tearing of engine component.
Yet traditional oil filter can not be removed the organic acid of the oxidation generation of machine oil in the machine oil own and the acidic materials such as sulphide that motor is in operation and produces.These acidic materials have reduced the working life of machine oil, can corrode simultaneously the component of motor, significantly shorten the working life of motor; Acidic materials are embodied in the piston ring zone to the damage emphasis of motor, and this will cause cylinder leakage tester, reduce engine power output, increase oil consumption, oil consumption increase; Not only can cause the serious carbon distribution in firing chamber after entering the machine oil burning of firing chamber, and can follow waste gas to enter outlet pipe damage after-treatment system, cause discharging to exceed standard.
Summary of the invention
In view of above-mentioned condition, be necessary to provide a kind of oil filter that can remove the machine oil middle acid substance.
A kind of oil filter, it comprises housing, the first filter element, the second filter element and alkaline filter unit.The first filter element and the second filter element are located in the housing.The alkaline filter unit is surrounded by the second filter element.The second filter element is surrounded by the first filter element.
The said engine oil filter cleaner cooperatively interacts by the first filter element, the second filter element and alkaline filter unit, and the impurity of machine oil or acidic materials are effectively removed, thereby can reach the purpose of removing the machine oil middle acid substance.
Description of drawings
Fig. 1 is the generalized section of the oil filter of the embodiment of the invention.
Embodiment
Below in conjunction with drawings and Examples oil filter of the present invention is described in further detail.
See also Fig. 1, the oil filter 100 of the embodiment of the invention comprises housing 11, the first filter element 12, the second filter element 14 and alkaline filter unit 16.The first filter element 12, the second filter element 14 and alkaline filter unit 16 are located in the housing 11.Alkaline filter unit 16 is surrounded by the second filter element 14.The second filter element 14 is surrounded by the first filter element 12.
Hold above-mentionedly, the first filter element 12 can be hollow cylindrical, and it is mainly used in stopping the large particulate matters such as metal fillings larger in the machine oil 20, greasy filth.The first filter element 12 can form by polypropylene is cotton, and the aperture of micropore can be 10～50 microns in the first filter element 12.Especially, it is that the stacked heat bonding of raw material forms that the first filter element 12 can adopt multi-layer polypropylene cotton, in bonding process, the three-dimensional microcellular structure that can form between layers of polypropylene cotton distributes, and the aperture of these microcellular structures is from increasing gradually near the second filter element 14 to the direction away from the second filter element 14, so that the hole structure in the first filter element 12 forms the gradient distribution, thereby strengthen the ability of the filtration of the first filter element 12.
The second filter element 14 can be hollow cylindrical, is used for filtering the macromolecular substances such as particulate, colloid or organic substance of machine oil 20.The second filter element 14 can be formed by hollow fiber ultrafiltration membrane, and the aperture of micropore can be 0.1 ~ 1 micron in the second filter element 14.
During use, machine oil 20 is respectively by the first filter element 12, the second filter element 14 and alkaline filter unit 16.Because cooperatively interacting of the first filter element 12, the second filter element 14 and alkaline filter unit 16, thereby the impurity of machine oil 20 or acidic materials are effectively removed.Especially, alkaline filter unit 16 can generate neutral salt with the acidic materials generation neutralization reaction of generation in the machine oil 20, thereby can reach the purpose of removing machine oil 20 middle acid substances.The removal of the acidic materials in the machine oil 20 can prolong the working life of machine oil, avoids acidic materials to the corrosion of engine component, prolongs the working life of motor, reduces the oil consumption of motor, reduces the discharging of harmful matter in the motor exhaust.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
