Background technology
With the continuous development of process of industrialization, more and more industrial machineries are used for industrial production, either mining machine
Tool or precision optical machinery, are required for using various lubricating oil.But since lubricating system leaks, the particle in air
Dust releasing and lubricating oil caused by dust enters in lubricating oil, is polluted to lubricating oil, or mechanical system is worn
Rotten colloid substance separated out of part fluid cracking etc. is caused also to be mixed into lubricating oil in high temperature, containing underwater operation for a long time, to it
Pollute.The lubricating oil being contaminated needs progress filtration treatment just to reuse, otherwise with regard to needing to outwell more to renew
Lubricating oil, cause lubricating oil waste and environmental pollution.
The lubrication oil filtration method provided in prior art, is usually traditional mechanical filter method, and mechanical filter method is usual
The filter of use includes plate filter, bag filter, ceramic rod filter and Electro Sorb absolute oil method etc..Wherein, plate
Frame filter mainly make use of the micropore sieving actoion of filter paper or filter cloth to remove particulate matter and mechanical admixture in fluid, using plate
The equipment volume of the oil filtrating equipment of frame filter usually larger and its filtering accuracy is relatively low, filter paper or filter cloth replacing more
It is cumbersome, cause the filtering accuracy of fluid low and of high cost.Bag filter generally use upper entering and lower leaving structure, generally in filtering
Particulate matter and mechanical admixture in the main crown_interception oil and water separation using filter bag, due to fluid in filter bag the residence time compared with
It is short, cause the filtering accuracy of bag filter low, and if required precision is higher or when impurities in liquid is more, can also cause
Filter bag easily blocks, and blowdown is more difficult when replacing frequently, and blocking, inconvenient.The filtering filter of ceramic rod filter
Core is micropore ceramics, can realize backwashing function, its main flow passage structure form has bottom into side to go out to go out two kinds the bottom of into side,
But the manufacturing process of ceramic rod filter core is complex, and the cost of manufacture of ceramic rod core is higher, and is using ceramic rod

Filter core, wherein separation layer are between the first sheet metal and the second sheet metal, when the first sheet metal and the second sheet metal conduction
Afterwards, the Three-dimensional static electric field of high intensity can be formed in the first sheet metal, the second sheet metal and separation layer, when fluid passes through fluid
Entrance enters after oil product filter body interior, and Three-dimensional static electric field can be to polarity charged particle thing and lubricating oil in fluid
The Organic Acid and Base nitrogen that produces in use, with reference to the electrically charged fluidity material of water isopolarity carry out adsorption filtration point
From the oil product after filtering is exported through filter core top fluid excludes oil product filter main body.Although the Electro Sorb in prior art is net
Oily method tradition machinery filter method is avoided in filter process existing for obstructing problem, improve filter efficiency, reduce
The lubrication oil filtration cost of enterprise, still, due to the electric field skewness of the formation between the first sheet metal and the second sheet metal
It is even, and the electric field strength produced is smaller, causes the clean-up effect of Electro Sorb poor, and the surface of sheet metal is smooth, and impurity is inhaled
Attached effect is poor.Therefore, a kind of Electro Sorb of continual exploitation refines filter core, to improve the precision of oil filtrating, particularly improves lubrication
The filtering accuracy of oil, reduces the production cost and obstructing problem of lubrication oil filtration, further improves the filter efficiency of lubricating oil, have
Help reduce industrial operation cost.
