Abstract
A filter that is used for filtering and heating gas oil uses the cup shell of density that sufficient amount is housed filtering agent liquid bigger than gas oil, and the rail of gas oil is immersed in this liquid.With a coiler whole cup shell is heated, coiler runs through cup shell, extends to the bottom from the top.Perhaps heat with a heating jacket that wraps on the whole height of cup shell.Heating machanism is connected on the coolant circuit of motor vehicle engine, and this motor is made fuel with gas oil.
Description
My this invention relates to the filter and the heater of a gas oil, and this gas oil product is intended for the fuel of motor vehicle.Here " gas oil " this title of usefulness is meant the fraction of the petroleum liquid that ratio of viscosities gasoline is big, be meant that especially its viscosity and boiling spread are situated between between gasoline and the lubricant oil, boiling point is generally 230 ℃ to 430 ℃, flash-point is about 60 °-70 ℃, and spontaneous ignition temperature is approximately 330 °-340 ℃ the sort of fraction.
In actual applications, with " gas oil " this name nominating, its common characteristic all is included in this scope for any product that can form the crystallization of wax shape sediments at low temperatures, as long as they can be as the fuel of motor vehicle.
Pointed as top definition, gas You And is not a kind of well-defined compound, but a kind of multi-component mixture of forming by many kinds of petroleum cuts.One of feature of gas oil is to contain paraffin, and paraffin tends to crystallize out at (just subzero about 4 ℃) under the lower temperature, and is doing with gas oil on the motor vehicle of fuel, and this temperature is actually and can runs into.The paraffin crystal of Xing Chenging will certainly stop up fuel filter like this, thereby has cut off the supply of fuel in the motor, and the Hang And of Yun that has interrupted motor causes parking.
In order to overcome this shortcoming, various technology were once proposed, one of approach is to add 15% to 30% regular gasoline when adorning gas oil at every turn, and gasoline is as a kind of solvent of paraffin wax, and if not, paraffin wax will be precipitated out.A kind of alternative way is to add special additive when every jar of gas oil of can.Yet they do not make us satisfied fully, and these two kinds of measures all can not guarantee crystallization do not occurring under some low temperature or under certain condition.
The work of can gas oil must separately be carried out with adding gasoline or additive in the container, and this true feasible operation is pretty troublesome.
Second approach adopting really of Ti Chu And is that a heating system (just being heated by resistive device) is set, before gas oil arrives filter, earlier with its heating.
Under some occasion, particularly under very low temperature, this way is unsafty, because gas oil cools down between heater and filter, still is enough to form some crystal.Another shortcoming is the temperature that need come control heater with a thermal switch.
The somebody described another kind of approach, for example at french patent documents FR-A-2177159, among FR-A-2179359 and the FR-A-1432595, the gas oil filter directly heats with a heat exchanger, and the heated fluid of supply heat exchanger is to come from the cooling circuit of motor.This heat exchanger is fixed on the bottom of filter usually, and therefore, it is only effective to the bottom of hot filtration apparatus in general.
When temperature was very low around, in general the heat of this heat exchanger was not enough, therefore must load onto an additional heater, and its form is a resistance heater.
F.P. FR-A-563799 has also announced the heating means of a gas oil filter, and it only is to heat on a sidewall of gas oil filter.Have been found that under low especially ambient temperature this mode of structure still can not be satisfactory.
At last, I should remind this fact: what use in the filtrating equipment of gas oil is paper filter, owing to need heat, and the replacing of filter cartridge is quite complicated, therefore, when the filter cartridge with papery filtered gas oil, experience showed have the impurity of a large portion being carried secretly the leakage past from filter by gas oil.
The main purpose of my invention provides a kind of equipment that gas oil filter and gas oil heater are combined, and this equipment has been eliminated above-mentioned those shortcomings.
Another object of the present invention provides a kind of device that can filter and heat gas oil, this device can be with all working under multiple mode all environmental conditionss to gas oil heating and filtration ， And and actual capabilities appearance in the usual use of a Motor Vehicle.In addition, this device relatively simple for structure, price is also cheap.
A further object of the invention just provides a kind of equipment that the filter of gas oil and heater are combined, and its performance has in actual use surpassed the performance of the early stage gas oil filter that uses in the motor vehicle fuel system out and away.
According to the present invention, reach three above-mentioned purposes and the some other purpose that it will be appreciated that below with a gas oil filter.This filter uses the hot water from the vehicle motor cooling system directly to heat; And and be made up of the cup-shaped Receiver that one or more and filter adapt, on the whole periphery of cup-shaped Receiver or on the surface, gas oil is heated with the hot water of receiving on the cooling circuit of the present invention; The liquid bigger than gas oil by means of a kind of density filters kerosene, can capture the impurity in the gas oil simultaneously, so just no longer needs with traditional paper filter.
Filtering agent liquid can be made up of water or a kind of dihydroxylic alcohols (particularly glycol) expediently, adds a kind of antioxidant and anti emulsifier (emulsion breaker just) in the liquid in the past.
Find that also another advantage is, in the liquid of higher density, add colorant or dyestuff, make filtering agent liquid different with the color of gas oil, like this, vehicle driver or the waiter of gas station are as long as have a look transparent oil storage tank simply, and whether just can investigate thoroughly soon has the filtering agent of enough ratios liquid in the storage tank.
According to characteristics of the present invention, filtering agent liquid is injected this cup shell, until reaching a predetermined liquid level, this liquid level position is above the gas oil oil inlet pipe, and the gas oil outlet is then opened the top at cup shell, and the exit position is on predetermined liquid level.
Therefore, the gas oil that is filtered is by entering at subsurface immersion tube (oil inlet pipe), and And and bubbling are by the higher liquid of density, formation one deck gas oil reservoir on higher density liquid.The particle of carrying secretly in the gas oil and other impurity are just stayed in the liquid of higher density at an easy rate, these impurity can be retained in the liquid with the form that suspends, perhaps, if they are to dissolve in this liquid, just be dissolved in the liquid of this higher density.
Therefore, the gas oil after the purification just is brought to ， And on the liquid level recited above and is introduced in the oil nozzle of motor.The liquid heating of the heat that the loop is come because whole cup shell is cooled, thereby filtering agent liquid has just constituted the heat exchange medium of a high heat capacity, the heating of gas oil is just effective especially.Because each bubble just has been heated when it forms, therefore, heat abundant especially.
According to characteristics of the present invention, the filtering agent cup shell is contained in another storage tank or cup shell the inside, and this cup shell and filtering agent cup shell separate each other, thereby have formed a heating resistance collar that surrounds the filtering agent cup shell fully.By being the space of annular basically between two cup shells, heating liquid is replaced.
In another method, filtering agent cup shell and the liquid that is placed in the cup shell can heat around pipe or coiler with a multiturn that is contained in the filtering agent cup shell.
These coilers contact with gas oil in cup shell, and they at least once preferably repeatedly are immersed in the filtering agent liquid of higher density.
From the explanation of doing below in conjunction with accompanying drawing, we can be well understood to above-mentioned and other purpose of the present invention, and characteristic and advantage, wherein,
Fig. 1 is the axial sectional view that first embodiment according to the invention obtains;
Fig. 2 is the axial sectional view that second embodiment according to the present invention obtains.
The device of Fig. 1 is made up of an interior cup shell 1 and an outer cup shell 2, and these two cup shells are radially separating each other, and normally coaxial, a cup shell is enclosed within the inside of another cup shell, thereby has formed an annular space 3.Filtering agent liquid is injected in the cup shell 1 up to predetermined liquid level L, and the filtering agent density of liquid will preferably be greater than water significantly greater than gas oil, this liquid level height be approximately container 1 height 1/3rd.
Top cover is divided into two parts, and a part is a disc-shaped structure 5, and another part is a cylindrical flanged dish structure 6, and the boss 5a of disk 5 extends in the middle of the flange plate 6.An annular groove 6a who lays seal ring 6b is arranged on the flange plate 6, and seal ring 6b is the compressible material of anti-petroleum cuts, for example the O type ring of silicone rubber or the ring of some other compressible structure.
The upper end portion of top cover 5 and 6 sealing cup shells 1 and 2.
Have on the disk 5 two crosspassages 7 and 9,10 and 11, two crosspassages of 8 and three axial passages extend transverse to cup shell 1 and 2 vertical (Vertical direction) the axle on.
Passage 9 is sealed by a stopper 17 that is screwed on the disk, and stopper 17 has a Sealing 14a, and path 10 then seals with stopper 20, and its lip ring is expressed as 14b.The stopper 21 of a band shape of passage 11 usefulness Sealing 14c seals.The direction that axial passage 9,10,11 extends normally parallels with the axis of cup shell 1.
Two passages 7 with 8 respectively be screwed in disk 5 on connecting tube 13 and 12 link up mutually, connecting tube 13 and 12 and disk 5 between seal with seal ring 14d and 14e respectively.Connecting tube 13 and 12 is connected on the oil circuit from the oil tank to the motor.
Introducing from connecting tube 12 needs the gas You And of heating to be injected into path 10 via passage 8, and gas oil enters lining 19 by path 10, and immersion tube 18 is sealed in lining 19 the insides, and the lower end perforate of this immersion tube is below liquid level L.
Therefore, the gas oil that enters with the bubbling state upwards, discharge by the filtering agent liquid 4 And of higher density and by the position of a volute 15 above liquid 4, volute 15 has a compression ring 15a, it is in place that it is compressed lining 16 clampings, and compression lining 16 is screwed on the boss 5a.The perforate of pipe 15 be positioned at filtering agent liquid levels L above, therefore with it collect through filtration and heating after gas oil ， And they are delivered to passage 7, deliver to connecting tube 13 later on again, gas oil enters engine nozzle from connecting tube.
For stopper 20 and lining 19 being installed and stopper 17 and lining 16 being installed, path 10 and 9 is all wanted internal thread on the car with the lower end in the top.Pipe 15 can be made a kind of capillary tube of coiling, so that the gas oil that makes away has long stroke.
Take stopper 17 away, just can clean capillary tube with air.
A part below the outer surface of flange 6, car have outside thread 24, and the ring 25 that has internal thread may be screwed on the flange 6, and ring 25 has a flange 26 inwards, and it is holding in the palm flange 2a, and 2a heads on convex shoulder 23 again, in such a way cup shell is bearing on the top cover.
Encircle 25 outer surfaces with mill, the method cutting of mill or annular knurl so that make people's hand or spanner can fasten it tightly.
The sidewall of flange 6 is provided with two passages 27 and 28, and these two aisle cart have internal thread, and they are linked up with aforementioned space 3 with 28a mutually by its branch road 27a.Passage 27 and 28 stretches along the direction substantially parallel with the axis of two cup shells 1 and 2 basically, and branch road 27a and 28a then extend along the direction substantially parallel with axis.Connecting tube 29 and 30 is externally threaded ， And and is to be screwed to passage 27 and 28 to get on, and the sealing between two connecting tubes and the flange 6 is with ring 14h and 14i.
Two connecting tubes 29 with 30 by two flexible pipes be connected with the coolant circuit of motor (flexible pipe is not shown on figure).Come in from connecting tube 29 from the freezing mixture of the next heat of motor,, discharge through connecting tube 30 again by annular space 3.
A pair of cushion block 31 and 32 makes the bottom of two cup shells 1 and 2 keep certain axially spaced-apart, and it can this cup shell to pop-up again simultaneously, is that shoulder 22 is withstood on the basis with cup shell 2.
Especially: the bottom 2c of cup shell 2 is provided with a center hole 2d, the band outside thread of cushion block 32 and the bolt physical efficiency of internal thread have no obstacle ground and pass from this hole, bolt fist 36 and cushion block 32 have a shoulder, seal with ring 14j between the upper surface of shoulder and bottom 2c.
With a nut bolt head 36 is fixed, nut is to be screwed on the outside thread 36 of these parts.
When cup shell 2 was locked in the appropriate position by sleeve 25, by the head and the body of bolt 31a of rotation stopper 41, cup shell 1 can be pushed down by shoulder 22 sealings.By cushion block 31 and 32 mutual thread engagement, can adjust bottom 1c and 2c spacing each other.
The axial bore 31a that runs through cushion block 31 is airtight by stopper 41, when stopper is opened, just can discharge filter liquide 4 from cup shell 1.
Be used among Fig. 1 filtering and to heat the work of hot filtration apparatus of gas oil as follows: in case device assembles by explanation requirements, just make and partly fill in the cup shell 1, then through connecting tube 12 and immersion tube 18 adding gas oils with filtering agent liquid by passage 11.The density of gas oil is lower than the density of filter liquide, therefore, the gas oil bubbling upwards by filter liquide focus on filter liquide upper surface L above, then, gas oil enters into the nozzle of filter through capillary tube 15 according to the mode of having narrated.Impurities is stayed in this liquid by heavier filter liquide capture ， And and with state of suspension or dissolved state in these gas oils.
Simultaneously, hot water that comes from the motor loop or freezing mixture flow through the annular space 3 around the cup shell 1, and the medium on the whole height of cup shell in this cup shell of heating comprises that gas oil and the liquid 4 above the liquid 4 is own.Can guarantee in this way to heat gas oil very effectively, and in fact can be heated to about 35 ℃ to gas oil.
Have been found that: with described this device, the gas oil in the motor can be fully burned, thereby the Economy of fuel can improve about 8-15%.Because gas oil fully burns, need not remove to wash the piston and the cylinder that have unburned fuel again, this has just reduced the wearing and tearing of these parts of motor widely.Really, I find that lubricant oil or engine oil saved about 50%.
Though filter liquide 4 can be made up of water, for better effects if, I would rather spent glycol, the preferably pure ethylene glycol of usefulness adding antioxidant and anti emulsifier.Use the filtered fluid of following ingredients can obtain optimal results: monoethylene glycol 96.5%(weight), 3.0%(weight) Sodium Benzoate antioxidant and 0.5%(weight) natrium nitrosum (anti emulsifier).
Done comparative trial with the gas oil that impurity content is high, find in test, can remove nearly all impurity with device of the present invention, only stay 10 gram impurity in every liter of gas oil, and with the filter of conventional papery filter core, the remaining impurities amount is every liter of gas oil 80 grams in crossing the gas oil that filters.
Flow on the Injection Pump if filter liquide is accidental, for example connecting tube 12 and 13 has connect instead on oil circuit, and in this case, antioxidant prevents that Injection Pump from getting rusty, and anti emulsifier prevents to form emulsion between gas oil and the filter liquide.
Also can be colorant, particularly phosphorescent coloring joins in the filtering agent liquid, even filtering agent liquid itself also can easily be come with the gas oil difference at night, like this, filtering agent liquid level height in the pollution level of filtering agent, the cup shell 1 can be seen clearly by transparent cup shell at an easy rate.
Colorant preferably is made up of the orange W200 and the 10 gram phosphor W742 of 10 gram solublies, and this prescription is enough for 1120 kilograms filtering agent liquid.Can notice, resemble the impurity of sulphur and so on, can not remove effectively with conventional paper filter, and just be dissolvable in water in the water with these impurity of system of the present invention, their solubility in alcohol is bigger, therefore, can effectively they be removed with fluid filter system of the present invention.So filter method of the present invention has reduced the pollution of atmosphere significantly.
It is quite simple cleaning the filter of representing on Fig. 1.Dismantle stopper 41 and just can discharge the filtering agent liquid that tarnishes, again load onto stopper then, fresh filtering agent liquid just can add to come in by pipe 18, before adding, clean stopper 20, capillary tube 15 and cup shell 1, also will clean stopper 17 and 21 in case of necessity.
In the embodiment that Fig. 2 represents, a filtering agent cup shell 101 only is set, the flange 101a car of cup shell 101 upper end portions has outside thread ， And and is screwed to lid 51, and it has a Sealing 122.
In this embodiment, have externally threaded sleeve pipe 119 that a cylindrical axial pipeline 118 is fixed in the axial center hole 110 by a car, center hole 110 is linked up mutually with path 10 8, and connecting tube 112 is screwed on the path 10 8, and connecting tube has Sealing 114e.
The two ends of coiler 52 link to each other with 54 with passage 53, and these two passages will connect two connecting tubes at coiler two ends respectively and link up mutually with the coolant circuit system of motor.
Therefore, the freezing mixture of heat just directly cycles through the inside of cup shell, and cup shell inside is heated fully.
The work of this hot filtration apparatus is undertaken by mode discussed above basically.
The embodiment of Fig. 2 is simpler than the embodiment of Fig. 1, and shared space is also few.
Should also be noted that this Fa Ming And is not limited to described several special embodiment, but be included in the various changes of making within the appended claim scope, for example, except water and ethylene glycol, can also use other filtering agent liquid.
