Description
The present invention relates to handle method that is stored in the liquid in the oil tank and the liquid injection apparatus that uses in the method, particularly relate to the method that oil tank comprises the various different types of liquid in the relatively large oil tank of Oil Tank and other this analogy that is stored in of handling, for example, for the fluidisation oil, prevent that sludge deposition or removing are deposited on the greasy filth of tank bottom, and relate to the liquid injection apparatus that to finish the liquid activation with high efficiency very.
When the pour point of the liquid of storing is higher than the temperature of oil tank inner air, reaching storaging liquid under a certain temperature of pour point at least in oil tank.For example, by the heating tube of ring-type or winding type is installed in the bottom of oil tank and make heated liquid or steam by heating tube, the liquid that stores in the oil tank is heated to said temperature.
When heating the liquid that in oil tank, stores by this method, heat the liquid above heating tube and make it present fluid state by thermal convection current,, under the heating tube or away from the liquid of heating tube outside the thermal convection current scope and present and lack mobile curdled appearance.Make liquid keep dead state owing to not mixing or flowing, this just is deposited as at tank bottom and solidifies shape fluid, comprises that major part is in the cured shape thing of suspended state, i.e. greasy filth.When oil tank did not heat, similarly state also can take place.
Do not have effective method to can be used for from oil tank flush away and remove this greasy filth, particularly be deposited on the greasy filth below the heating tube, the workpeople has to use after oil tank discharges most of liquid spoon shovel or other similar tool to remove greasy filth.
Disclose in the method for fluidisation from the oil oil tank of floating type top cover that discloses in civilian clear 63-44147 number and the greasy filth of removing deposition in Japanese Utility Model, can be installed on the cylindrical hole of the suitable supporting of floating top cover by crooked cylindrical shape washer in flexible connection place, under high pressure the cleaning fluid from the washer ejection decomposes and fluidisation greasy filth, and the greasy filth of fluidisation is pumped and discharges the outside of oil tank.
Usually the method for removing greasy filth is to rely on manpower, and not only efficient is very low and time-consuming and dangerous for this, produces explosion hazard gases because inflammable gas is full of oil tank inside.From personal security and healthy viewpoint, it also relates to many difficult points, and for example, the suction (inflammable gas is a kind of anesthetic) by inflammable gas causes the influence of the pernicious gas of accumulation to workers ' health.
Also be included in the cylindrical shape washer of installing on the cylindrical hole of mobile top cover upper support of oil tank of portable top cover that can turn in the method.Under high pressure the cleaning fluid from the washer ejection dissociates and fluidisation greasy filth, and the greasy filth pumping of fluidisation is discharged outside the oil tank.Under high pressure, must spray liquid from the washer that is installed on the top cover, so that disassociation greasy filth.It is essential that this method is used on the main equipment.Must move because the support column of washer is installed, and the intensity of top cover supporting reduces significantly, this makes must carry out work on the top of unsubstantial mobile top cover, and this also is dangerous.
For example, make and clean more than 80 meter of diameter in this way, high more than the 20 meters oil tanks that can store 100,000 tons of left and right sides oil, if finish the greasy filth that fluidisation is deposited on tank bottom apace safely, and about 30 washers need be installed on top cover, need all washers atomizing of liquids under high pressure, so that purging system becomes is very huge.In addition,, the complicated network of flexible pipe, carrier pipe, switching valve and arm or the like is installed, need do a large amount of work in order to carry these hydraulic oils.This has just increased the possibility of causing danger in the washing and cleaning operation process.The another one problem is that the washer installed is defined diameter on the top cover of the oil tank of portable top cover small, because by the little pillar hole of diameter, washer can enter the inside of oil tank, this is elevated to enough intensity to the pressure by the washer atomizing of liquids with regard to being not easy, and has so just limited the efficient of washing and cleaning operation.
Because the highly pressurised liquid that can not be easily sprayed by washer from the oil tank external control, and can not determine the progress of greasy filth removing operation exactly, this just makes it can not adopt the operation sequence that adapts.
Because these defectives of prior art, need the method for a kind of liquid activation of research and can utilize the very simple equipment liquid injection apparatus of atomizing of liquids under high pressure, can be with easily and the quantity and the direction of accurate method control atomizing of liquids, and can carry out other processing with the greasy filth of the reliability of height and high efficiency fluidisation deposition and to it.

When after discharging most of oil or other analog, carrying out the cleaning of oil tank 31, because common washer 1,1 ' directly cleaning fluid is injected on the oil tank, so greasy filth is fluidized easily.On the other hand, when removing the oil that is present in the oil tank 31 or analog from the cleaning fluid of washer 1,1 ' injection, the stirring action by the cleaning fluid that sprays causes the action of turbulent flow of wet goods and fluidisation greasy filth.So after the wet goods with oil tank mixed, the greasy filth of fluidisation can be discharged from oil tank.
The washer 1 of implementing oil tank cleaning method of the present invention is described referring now to Fig. 4 to Fig. 8.
Washer framework 2 is installed in and covers on 34, and lid 34 is installed on the opening portion 33 of oil tank 31 again.
In washer framework 2 inside case 4 is arranged, and stretch out from case 4 relative two ends first circle tube member 5 and second round member 6 are set.Circle tube member 5,6 can rotate by the supporting of the bearing on the two lateral walls that is arranged on washer framework 27.So the case 4 in the washer framework 2 can be vertically around circle tube member 5,6 swings.
Like this, first rotating shaft, 3 lateral extensometers are crossed the middle body of washer framework 2, first circle tube member 5 by case 4 also makes its end bearing on the bearing portions 10 that forms on second circle tube member 6, and first circle tube member 5 and second circle tube member 6 can both be by washer framework 2 the supporting of bearing 7 rotate, so, when the supporting by the fixing bearing 7 of circle tube member 5,6, case 4 can be vertically rotates around the axis of first rotating shaft 3.
With first worm screw 11 " first worm gear 12 of engagement is fixed on the extension of first circle tube member 5 that outwards protrudes from a sidewall of washer framework 2, and first worm screw 11 is connected with first power source 29 that changes rotation direction (air engine, hydraulic motor or other similar engine) with freely regulating the speed ".
When first worm screw 11 drives by first power source 29, its rotation noticeable deceleration ground is delivered on first circle tube member 5 by first worm gear 12, so that make first circle tube member, 5 slow rotation, therefore, the case 4 in washer framework 2 vertically rotates around bearing 7.For example, when case 4 has rotated to the angle of regulation, be arranged on the position sensor 13 that covers on 34 detect the lip-deep test section 13 that is arranged on first worm gear 12 ', so first power source 29 changes the direction of rotating and causes that case 4 rotates in the opposite direction, so case 4 swings back and forth around first rotating shaft 3 in by position sensor 13 and test section 13 ' determined fixed range by first power source 29.The method of position sensor 13 energy electricity consumptions, light or machinery is operated, and makes it have the scope of the operation can regulated.Test section 13 ' surface printing or be carved with angle scale 13 ", therefore, position sensor 13 and test section 13 ' can be as the indicator of case 4 vertical rotational angles.So can easily outside oil tank, find out the lengthwise position of rotating box 4.
The interior middle body of enclosed first rotating shaft 3 that is formed by dividing plate frame 8 has second worm screw 14, and is arranged on the travelling gear 15 of the end of first rotating shafts 3 that first round member 5 outwards protrudes for rotation first rotating shaft 3.Travelling gear 15 and the 3rd worm screw 28 that is connected on second power source 30 (air engine, hydraulic motor or other similar engine) are joined.As first power source, the direction that second power source 30 can freely be regulated the speed and rotate.The end of first rotating shaft 3 has cylindrical cavity 16, on the inner surface in the chamber of cylindrical cavity negative thread is arranged, on the outer surface of an end of feeler 17, have can and the pin thread of negative thread toe joint, feeler 17 partly is screwed into cylindrical cavity 16, being bearing in the cylindrical cavity 16 outer remainders that protrude can slide at axis direction, but can not rotate.For example, sensor activation members 18 is arranged on the projection of feeler 17, and sensor device 18 ' be fixed on and cover on 34, so that in the moving range of sensor activation members 18, measure the position of feeler 17.When electricity, light or mechanical 18 ' time an of sensor device of method startup, just change the rotation direction of second power source by sensor activation members 18.
In addition, feeler 17 is provided with pointer 19, in the moving range of pointer 19, be provided with fixing angle scale 19 '.
Like this, when driving travelling gear 15, just rotate first rotating shaft 3 and second worm screw 14, thereby cause that feeler 17 axially moves by the rotation of second power source 30.When the projection of the feeler 17 that leaves cylindrical cavity 16 arrives assigned position, sensor device 18 ' detect existence of sensor activation members 18 and for a change the rotation direction of second power source 30 send signal.So travelling gear 15 rotates first rotating shaft 3 and second worm screw 14 in the opposite direction, thereby cause that feeler 17 retreats shift-in cylindrical cavity 16.When feeler 17 has entered the predetermined distance of cylindrical cavity 16, the existence of another sensor device 18 ' detect sensor activation members 18 and for a change the direction of second power source 30 send signal, so change the rotation direction of first rotating shaft 3 and second worm screw 14 once more.
So, by select rightly two sensor devices 18 ' between distance and the position relation of they and feeler 17, make first rotating shaft 3 ± 90 ° of scopes in back and forth rotation be possible.
Cylindrical shape second rotating shaft 20 on end in the U-shaped inside of dividing plate frame 8, the top and bottom of this second rotating shaft and fluid passage 9 are connected.By the 21 rotatably support cylindrical shapes of the bearing on the upper and lower plate portion that is arranged on dividing plate frame 8, second rotating shaft 20.

The tail end of second circle tube member 6 seals.Liquid-tight form is connected on the sidewall of second circle tube member 6 cleaning fluid inlet tube 24 rotating.The inlet tube 24 and second circle tube member 6 are to be connected by the hole on the sidewall of second circle tube member 6 25.
Under high pressure cleaning fluid enters second circle tube member 6 from inlet tube 24 by hole 25; Enter the fluid passage 9 and second rotating shaft 20 by second circle tube member, 6 bearing at end parts 10; Again from second rotating shaft 20 to nozzle 22, under high pressure from the spout 22 ' ejection cleaning fluid of nozzle 22.
As previously described, when the travelling gear 15 that rotates by second power source 30 is delivered to first rotating shaft 3 and second worm screw 14, this rotation is delivered to second worm gear 23 with the speed that reduces again, so nozzle 22 can flatly rotate around second rotating shaft 20 with a direction, till above-mentioned feeler 17 moves simultaneously, the result cause by a sensor device 18 ' the detection of sensor activation members 18, meanwhile change the rotation direction of second power source 30, the direction that nozzle 22 also changes and rotates is so nozzle 22 rotates in fixed range to and fro.Can by observe pointer 19 with respect to angle scale 19 ' the position outside oil tank, control nozzle 22 this rotation in the opposite direction.
In addition, because can use control valve or analog in the drive fluid supply pipe controls from the supply of the drive fluid (oil or air) of oil sources 49, thereby change the speed that first power source 29 and second power source 30 make nozzle 22 swings, so can control the rotation of nozzle 22 vertical and horizontal from the outside by controlling first power source 29 and second power source 30.Thereby can realize that compound rotation mode controls nozzle 22.What be used for first power source 29 and second power source 30 is to drive engine or pump by air or oil, and does not make electricity consumption, and this is because the air at the installation scene is explosive inflammable gas, and electrical installation or static are very easily lighted these gases.
Narrated hereinbefore and be installed in the washer of the present invention 1 that covers on 34 and behind mounting cover 34 on the opening portion 33, high-pressure cleaning liquid is supplied to inlet tube 24, first power source 29 alternately rotates case 4 by the effect of first worm gear 12 and first circle tube member 5 in the opposite direction around first rotating shaft 3, like this, by the case 4 that rotates, make nozzle 22 upper and lower swings, second power source 30 alternately rotates first rotating shaft 3 by travelling gear 15 in the opposite direction.Like this, by the nozzle 22 that swings back and forth on the horizontal direction that acts on of second worm screw 14 and second worm gear 23, so, spout 22 ' on vertical and horizontal, swing back and forth within the limits prescribed and with the speed of stipulating.Therefore, can spray highly pressurised liquid with complex patterns.
As shown in figures 1 and 3, fuel feed pump 42 is connected on the inlet tube of washer,, just can and discharges greasy filth from oil tank and clean oil tank by fluidisation greasy filth from the spout 22 ' ejection high-pressure cleaning liquid of nozzle 22.
If desired, the shallow slot part 26 that can form by the end at feeler 17 can limit the ultimate range that feeler 17 protrudes, when feeler 17 arrives the protrusion degree of regulation, the brake bar 27 that on lid 34, is provided with just and the shallow slot part 26 that is positioned at the end of feeler 17 contact.
Though in the above among Xu Shu the embodiment, what can mount and dismount from the opening portion that the oil tank lower sidewall forms covers the installation liquid injection apparatus, but also can cover the installation liquid injection apparatus, and same fully wash operation what can mount and dismount from the opening portion that tank top forms.This device does not use lid can directly be installed on the sidewall of oil tank yet.
