Description
Technical field
The invention belongs to mechanical field, relate to a kind of oil product cleaner, especially a kind of replaceable cartridge, the reusable cleaner of housing miscellaneous part.
Background technology
Engine fuel is producing, is transporting and deposit and can produce and be mixed into a large amount of impurity in process.Clean fuel oil also can produce metal-oxide after storage a period of time, precipitate out the pollutant such as colloid, asphalitine.The fuel oil of severe contamination can cause that the abrasion at the positions such as electromotor injection system and combustor and carbon distribution generate so that electromotor fuel consumption in use for some time increases, the hurried rising of exhaust emissions amount.Solution general at present is to install oil product filter on the engine, removes the impurity in oil product, colloid, asphalitine and moisture etc., makes fuel oil clean.Clean fuel oil 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.Overall rotatable filter housing is provided with oil-in and oil-out, 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 as a whole, 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.Have drawbacks in that firstly, since metal shell is longer than the filter element organic material life-span more than 10 times, but disposable can only discard and cause great waste.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, usual 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, 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 invention can carry out filter element replacing after dismantling, it is to avoid waste.But there is structure complexity in using, 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, namely 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 filter element.
In addition existing different manufacturers produce cleaner overall dimensions differ, 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 change filter element time cause certain trouble.Have to change the filter element of different manufacturers often with filter block, housing also together with change, which adds unnecessary expense.
Two, the material of filter element and structure are improper
The oil product filter of domestic more than 98% uses wood pulp filter paper, high accuracy composite filter paper or wire netting to be filter material at present, to reach to remove the purpose of impurity and moisture in oil product.The circulating resistance of high accuracy filter paper is big, 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.
Current material melt-blown process is widely used in the manufacture of polypropylene material for core.Melt-blown is exactly that after high temperature is extruded, polymeric material is formed superfine cellosilk, and prepare into 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 generally all contains alkane, alkene, cycloalkane, aromatic hydrocarbon, polycyclic aromatic hydrocarbon and a small amount of sulfur, nitrogen compound etc., contact oil product can cause that polypropylene articles is 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 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 capable of withstanding the corrosion by 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.
Application number be 200510040447.2 Chinese patent disclose " oil-water separating net of a kind of super-hydrophobic/super-oleophilic ", it is proposed to the thin film of and oleophylic hydrophobic at fabric web overlying lid layer, utilize 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, namely adopts hydrophobicity filter material, is separated by water, and " dredging " aqueous of filter material can be more good from fuel oil, and its effect separating water is more good.But this film producing process of Problems existing is complicated, and other filtering function and index are not good, it is difficult to obtain practical popularization.
Summary of the invention
