The working principle of the utility model is as follows:
the fuel oil flows into the module filter 2 and the coarse filter 1 in sequence from the bottom of the shell 4, is primarily filtered, reaches the precision requirement of the oil pump 3, is conveyed into the fixed cylinder 10 by the oil pump 3, and is filtered by the pleated paper filter 11, specifically, is filtered by the filtering composite paper structure 12.
After being contacted with the filtering composite paper structure 12, the fuel oil to be filtered is filtered sequentially through the spunbonded protective layer 16, the melt-blown coarse silk layer 17, the melt-blown medium silk layer 15, the melt-blown fine silk layer 14 and the wood cellulose filter paper layer 13. The spunbonded protective layer 16 can effectively prevent fiber overflow caused by fiber shedding in the melt-blown coarse filament layer 17, the melt-blown medium filament layer 15 and the melt-blown fine filament layer 14, so that the integrity of the filtering composite paper structure 12 is kept in the use process, and meanwhile, the larger pore size of the spunbonded protective layer 16 cannot influence the efficiency of the filtering medium. The melt-blown coarse filament layer 17, the melt-blown middle filament layer 15 and the melt-blown fine filament layer 14 are sequentially arranged, and a gradient filtering effect is well formed, so that larger particles can be intercepted by the melt-blown coarse filament layer, medium particles can be intercepted by the melt-blown middle filament layer, and smaller particles can be intercepted by the melt-blown fine filament layer. Compared with the traditional composite paper scheme of adding a layer of melt-blown non-woven fabric into wood fibers, the filtering composite paper structure 12 adopts the gradient filtering design, so that the filtering effect is better, and the filtering precision is higher.
Because the melt-blown coarse filament layer 17, the melt-blown intermediate filament layer 15 and the melt-blown fine filament layer 14 all comprise melt-blown non-woven fabrics, the function of containing particles to be filtered in the channels of the melt-blown coarse filament layer 17, the melt-blown intermediate filament layer 15 and the melt-blown fine filament layer 14 can be exerted to the maximum extent, and therefore the dust holding capacity of the filter medium is greatly improved.
The dust holding capacity of the composite paper made of the traditional wood fiber and a layer of melt-blown non-woven fabric is usually 80-120 g/square under the test condition of ISO19438, and the dust holding capacity can be improved to over 180 g/square by adopting the design of the filtering composite paper structure 12. Therefore, the dust holding capacity of the filter material can be greatly improved under the condition of the same filtering area and the same filter material thickness by adopting the design of the utility model.
The filtering composite paper structure 12 realizes the compounding of the melt-blown layers with different filament diameters by changing the structure of melt-blowing single filament diameter of the traditional composite paper, achieves the effect of gradient filtering, effectively separates and filters particulate matters with different sizes layer by layer, and compared with an oil supply structure using the traditional composite non-woven fabric for filtering, the filtering composite paper structure 12 has obvious improvement on the dust holding capacity, thereby being a good solution for the filter with the whole service life of filtering the automobile fuel.
