Description
Technical field
This utility model belongs to mechanical field, relates to a kind of oil product cleaner, especially a kind of replaceable cartridge, the reusable cleaner of housing.
Background technology
Engine fuel can produce and be mixed into a large amount of impurity during producing, transporting and deposit.Clean fuel oil also can produce metal-oxide after storage a period of time, separate out the pollutant such as colloid, asphalitine.The fuel oil of severe contamination can cause the abrasion at the positions such as electromotor injection system and combustor and carbon distribution to generate so that power-equipment fuel consumption in use for some time increases, the hurried rising of exhaust emissions amount.The most universal solution is to install oil product filter on the engine, removes impurity, colloid, asphalitine and moisture etc. in oil product, makes oil product clean.Clean oil product can improve efficiency of combustion thus saving fuel oil, reduction discharge；Also can reduce electromotor heel and toe wear, increasing service life of engine, make electromotor slow down along with the trend extending oil consumption increase of the time of use.But existing oil product filtering product is primarily present problems with:
One, the design of cleaner is unreasonable
Existing commercially available diesel fuel filter, it mainly has two kinds of forms, one to be overall rotation fitting type, and one is dismantled and assembled replacing filer element type.It is provided with oil-in and oil-out on overall rotatable filter housing, and is connected with outside oil inlet passage and oil discharge passage by filter block.Filter element is arranged in housing, and housing and filter element are an entirety, can not individually dismantle.In filter element service life to after date, it is necessary to by filter element and housing integral replacing, the filter case after replacing can only be discarded.Having an advantage in that filter block is connected by standard thread with housing, be suitable for standardized production, housing, filter block interchangeability are good.Shortcoming is: firstly, since metal shell is longer than the filter element organic material life-span more than 10 times, but can only disposably discard and cause waste greatly.Secondly as the process recovery process difference of the recovery processing technique of metal and organic material is very big, split cutting is made troubles again when reclaiming, and causes great environmental pollution.3rd, owing to overall rotatable filter is disposable products, consider for cost and service life, that the diameter of filter element and length are done is relatively big, and filter element is little with the gap of housing, and trapped fuel amount is few, add the circulating resistance of cleaner, generally circulating resistance index has just met the upper limit being distinctly claimed in GB, and circulating resistance index is the smaller the better in practice, and this point limits filter effect.
Chinese patent disclosed in 2007 " Split type housing of oil filter 200710110802.8 " discloses a kind of dismountable cleaner, and shell is made up of threaded upper bowl and lower bowl, is provided with sealing ring between upper bowl and lower bowl；Upper bowl is threadeded with the flowline of machine oil base by nut, and the periphery of upper bowl is provided with carrying out the bulge-structure that radial rotating is spacing between upper bowl and machine oil base, and this utility model can carry out filter element replacing after dismantling, it is to avoid waste.But it is complicated to there is structure in Shi Yonging, parts are many, the shortcoming that filter element replacing is constant, and detachable part is on the housing of cleaner, need this position for this, i.e. go up the joint portion of bowl and lower bowl and carry out special sealing, and there are vibrations etc. affect because vehicle is in operation, likely there will be loosening and oil product leakage of this joint portion, cause the inefficacy of whole cleaner.
The cleaner overall dimensions that the most existing different manufacturers produces differs, and installing/dismounting mode also differs, cause the housing of first factory, filter element cannot with the filter block of second factory with the use of situation, user causes certain trouble when changing filter element.Have to change the filter element of different manufacturers often with filter block, housing also together with change, which adds unnecessary expense.
Two, material and the structure of filter element are improper
The oil product filter of the most domestic more than 98% uses wood pulp filter paper, in high precision composite filter paper or wire netting to be filter material, to reach to remove impurity and the purpose of moisture in oil product.The circulating resistance of filter paper is big in high precision, water environment capacity is poor, service life is short；Though wood pulp paper and wire netting have the advantage that circulating resistance is little, but filtering accuracy is low, filter efficiency is poor.These several filter materials all can not meet the requirement that in industrial processes, oil product is filtered by equipment, causes the problems such as equipment failure rate height, low, the lost of life of operational efficiency.
During material melt-blown process is widely used in the manufacture of polypropylene material for core at present.Melt-blown is exactly that after high temperature is extruded, polymeric material is formed superfine cellosilk, and it is prepared as corresponding shape and structure, it is strong that polypropylene melt-blown filter material has water environment capacity, filtering accuracy advantages of higher, and it is prone to batch production, but it is currently only used for the filtration of air and water, this is because industrial oil the most all contains alkane, alkene, cycloalkane, aromatic hydrocarbon, polycyclic aromatic hydrocarbon and a small amount of sulfur, nitrogen compound etc., contact oil product can cause polypropylene articles to be dissolved corrosion for a long time, it is swelled into grume, lose filter capacity, therefore, polypropylene melt-blown filter material cannot be applied to industrial oil filtration art.
Therefore from the point of view of the filtering perspective of industrial oil, it is badly in need of the melt-blown filter wanting a kind of special material to make through melt-blown process, and the advantage with conventional meltblown filter element, it is resistant to the corrosion of the oil products such as diesel oil, gasoline, ethanol simultaneously, and the Colophonium contained in oil product, water, dust, mechanical admixture etc. can be filtered, especially there is certain oil-water separation.
The Chinese patent of Application No. 200510040447.2 discloses " oil-water separating net of a kind of super-hydrophobic/super-oleophilic ", proposes to cover one layer of hydrophobic and thin film of oleophylic in fabric web, utilizes the hydrophobic function of thin film, it is achieved the oil-water separation in oil product.This is the technical thought that current oil product filtration art is commonly used, i.e. uses hydrophobicity filter material, is separated by water, and " dredging " aqueous of filter material can be the best from fuel oil, and its effect separating water is the best.But this film producing process of problem existed is complicated, and other filtering function and index are the best, it is difficult to obtain practical popularization.
