Abstract
The invention discloses a pollution-free double-stage oil-water separation diesel oil filter. The filter comprises a filter seat (1), a housing (5), a filter core assembly (3), a water collecting cup (8), a sealing ring and an air bleed valve (16), and is characterized in that a flow guide vane (2) is sleeved in the filter seat; the upper part of an upper end cover (14) of the filter core assembly is sleeved on an oil outlet channel in the filter seat; a disc type spring (6) is arranged at the lower end of a lower end cover (11); the edge of the disc type spring is embedded in a positioning groove at the internal lower part of the housing; a support frame (12) is sleeved between the upper end cover and the lower end cover of the filter core assembly; a folded filter paper (3) is sleeved outside the support frame; an organic fluorine layer is additionally coated on an oil inlet surface of the filter paper; the upper end of the housing is connected with the filter seat through looseness-proof screw threads, and the lower end of the housing is connected with the water collecting cup through looseness-proof screw threads; and a water drain valve (10) is arranged at the lower part of the water collecting cup. The filter has the advantages that the service life of filter core capable of efficiently separating oil and water can be prolonged, only the filter core assembly needs to be replaced during maintenance, and waste filter cores can be treated in a pollution-free manner, so that the emission of hydrocarbons is effectively reduced and metal materials are saved.
Description
Technical field
The present invention relates to a kind of diesel-oil filter, relate in particular to a kind of nuisanceless twin-stage oil-water separation diesel-oil filter.
Background technique
As everyone knows, in order to improve power and to reach strict emission control standards, the almost all superchargings of Hyundai Motor diesel engine, in cold and adopt Electrocontrolled high-pressure to advise technology altogether.What therefore the oil supply system of modern diesel engine was abstained from most is to contain moisture content in the diesel oil.Current research shows, moisture content runs into the high-temperature gas the cylinder after the spray orifice ejection, and its volumetric expansion will reach 1600 times, be equivalent to blast, even if moisture content also in the end of spray orifice, the expansivity of its moisture content also has explosion effect.Tend to cause the plastic deformation of spray orifice, make the fuel feeding debase of diesel engine, it is out of control to cause burning, and discharging exceeds standard.And the oil-water separation performance of existing diesel-oil filter mainly is to rely on the filter paper of handling through organosilicon, function by its repulsion water, affine oil is carried out oil-water separation, but its working life is too short, test by the test method of SAE J1839-1997 in the laboratory, the time of general efficient oil-water separation has only 1～1.5 hour, after this, divide dried up efficient sharply to reduce.Simultaneously, existing its filter core of rotation fitting type diesel-oil filter all is canned, more all exist during renew cartridge at every turn and take away one jar of oil, and these oil finally all will be discharged into the atmosphere with the form of hydrocarbon, and atmosphere is polluted.When adding more renew cartridge, the steel tank of pot type filter core, spring, thread plate are difficult to carry out nuisanceless processing, and not only befouling environment also causes the problems such as significant wastage of iron and steel resource.
Summary of the invention
The objective of the invention is to provides a kind of working life, maintenance that can prolong the efficient oil-water separation of filter core with pre-filter device the time only need change filter core assembly for overcoming the deficiencies in the prior art, can effectively reduce hydrocarbon emission, save the nuisanceless twin-stage oil-water separation diesel-oil filter of metallic material.Its concrete technological scheme is: nuisanceless twin-stage oil-water separation diesel-oil filter, comprise filter block, housing, filter core assembly, collecting bowl, seal ring, bleed valve, be set with guide vane in the filter block, the upper end cap top of filter core assembly is set in the oil discharge passage in the filter block, the lower end cap below has disc spring to hold filter core assembly, the disc spring edge is flush-mounted in the locating slot of bottom in the housing, on the filter core assembly, bearing support is housed between the lower end cap, the outer suit of bearing support is rolled over filter paper more, filter paper surface system handles through organosilicon, the oil-feed face of filter paper increases and scribbles one deck Organic fluoride layer, the upper end of housing is connected with filter block by screw thread, the lower end of housing is by the collecting bowl that is threaded, and the bottom of collecting bowl is provided with discharging valve.
Said guide vane, its channelization angle are 20 °～40 °.
Said filter block and housing, housing is threaded with collecting bowl, employing be half trapezoidal checknut, half trapezoidal junction plane of housing top screw thread down, lower housing portion screw thread half trapezoidal junction plane up, its junction plane and filter cleaner axis normal when being threaded.
Said filter block and housing, housing and collecting bowl, filter block is connected with upper end cap, and its fit tolerance is H7/g6, and the O RunddichtringO is all adopted in sealing.
Said discharging valve adopts left hand thread to cooperate with collecting bowl, and a rectangular seal is arranged at the spool top that discharges water.
The parts lower end cap of said filter core assembly, bearing support, filter paper, upper end cap all adopt the material of energy perfect combustion.
When using the nuisanceless twin-stage oil-water separation of the present invention diesel-oil filter, oil circuit and its connection of diesel engine can be used, when filter core assembly need be changed, back out housing, the filter core assembly that need are changed takes out, and loads onto new filter core assembly, tightens housing again and just can carry out diesel oil oil-water separation again.
From technological scheme of the present invention as can be seen, because the nuisanceless twin-stage oil-water separation of the present invention diesel-oil filter has at first adopted flow deflector structure, the oil stream that enters filter cleaner is rotated along housing, utilize the centrifugal force of its generation that the globule bigger in the diesel oil and pollutant are separated from oil stream, realized the first order centrifugation of diesel oil and water, the results showed first order centrifugation, its pre-filtration effectiveness can reach 40% to 70%, on original surface of handling of filter paper, increase in addition and be coated with one deck Organic fluoride layer through organosilicon, make full use of the characteristic that it repels water affinity oil, the better effects if of Fen Liing not only, and greatly prolonged the working life of filter core, our experiments show that the efficient of its separated free water can reach more than 98%, separate breast and divide the efficient of water to reach more than 95%.Simultaneously, because filter core assembly can be changed separately, can emit diesel oil earlier during each the replacing, eliminated the defective of original rotation fitting type diesel-oil filter, and but the filter core assembly parts of the nuisanceless twin-stage oil-water separation of the present invention diesel-oil filter all adopt the material of perfect combustion to make, and can utilize it to carry out combustion power generation.In sum: the present invention only needs the renew cartridge assembly when having reached working life that can prolong the efficient oil-water separation of filter core, maintenance, can effectively reduce hydrocarbon emission, saves metallic material and be replaced the goal of the invention that the filter core assembly that gets off can be realized nuisanceless processing.
