This elongated elements can be the sparge pipe on the carbon black remover, and this carbon black remover is used to remove a tube wall of conduit that is connected with heat exchange medium and contains the flue gas of flue dust and (sees DE-OS4142448).The current that ejected by this carbon black remover are disposed the flue dust of deposition from tube wall.In order to make this injection water can topped whole tube wall surface, this sparge pipe be in moving process, and its port of export should be horizontal and be in vertical position in its another section road in the stretch way, thereby forms the movement locus of a bending.Above-mentioned injection track realizes in the following way, drives a mandrel constant speed and rotate and drive another mandrel after this and rotate in certain certain time period.Work under coarse working environment, mandrel can be because of dirt or the wearing and tearing difficulty that turns round.In this case, owing to mandrel was controlled with the time, thereby may before the predetermined flex point on the injection of the no show still track, just switch to another new direction of motion.So just make tube wall can not get cleaning completely.
For above-mentioned carbon black remover is only removed the contaminated area that is limited by surface or side face, a kind of control device is disclosed in DD-PS281452.In this control device, there is a jet graphics that adapts with tube wall surface structure and the dustiness that records by vision.This jet graphics flows to this mandrel by a signal generator and motion detection device.
The object of the present invention is to provide a kind of method that is used to control the motion that belongs to the element that supports with two universal joints, make its motion can strictly follow a jet graphics that constitutes by the track that repeatedly overturns and carry out.
Control method of the present invention depends on displacement and does not rely on the time, can record the displacement of universal joint and the accurate location that moving meter is treated in assurance thus exactly.In the case, displacement measurement finally depends on the driving mechanism of element.Best pull-in frequency adjusting device is used to regulate the rotating speed as the alternating current generator of mandrel drive unit in this control.By this speed setting unit, adjusted the action period that is injected in the jet in a certain tube wall district corresponding to the dustiness on the tube wall.Because control of the present invention is only relevant with displacement, thereby to introduce transformation of speed mechanism be highly significant, and the speed that can make jetting stream move thus can not have influence on the accuracy that realizes injection scheme.
Below one embodiment of the present of invention shown in the drawings will be described in further detail, wherein:
Fig. 1 is the side view of carbon black remover;
Fig. 2 is a circuit diagram;
Fig. 3 is a jet graphics.
A water jet carbon black remover comprises a sparge pipe 1, as the current of ejection medium this pipe of flowing through.The port of export of this sparge pipe 1 is by in the combustion chamber that is inserted into a steam generator that is limited by tube wall by cover plate 2 blind bores.Sparge pipe 1 is supported on the cover plate 2 by one first universal joint 3.The rear end of sparge pipe 1 is fixed on one second universal joint 4.Second universal joint 4 is fixed on the pilot sleeve 5, and this sleeve can move axially on one first mandrel 6.First mandrel 6 drives by an alternating current generator 7.The two ends of first mandrel 6 are arranged on two second mandrels 8 that are parallel to each other and can move along its axis.Alternating current generator 9 directly drives one second mandrel 8 and drives another second mandrel 8 by chain transmission 10.When first mandrel 6 rotated, pilot sleeve 5 promoted second universal joint 4 and vertically moves, and made the port of export of sparge pipe 1 thus and all produced vertical displacement by the jet of this outlet injection.Similarly, when second mandrel 8 rotated, jet produced horizontal displacement.
By between mandrel 6,8, alternately switching, promptly produced injection scheme as shown in Figure 3.This injection scheme is made of horizontal segment and vertical section, and the transfer point of mutual conversion is wherein arranged.A reference point PO is arranged on injection scheme, and this point is as the initial point of this coordinate system.Displacement between first flex point on starting point PS and the horizontal direction is X1, in the horizontal direction turn left a little and turn right a little between displacement be X2.Mandrel 8 works in above-mentioned displacement process.Make jet vertically during displacement when switching to mandrel 6, this displacement is Y1.XY is illustrated in mandrel 6,8 and plays institute's time spent, the displacement between the transfer point.The coboundary of injection scheme is represented by Y2.Frame line Z has represented the base region by the injection scheme of driving mechanisms control.
As shown in Figure 2, on first mandrel 6 and one second mandrel 8, respectively be provided with two contactless inductance type limit switches 11,12,13,14. Limit switch 11,12 can be determined the route of 4 processes of second universal joint thus by the rotation of impulsive measurement mandrel 6,8 according to geometrical relationship.Limit switch 13,14 is used for determining reference point PO.But limit switch 11 to 14 is connected with the control device 16 of a computer program stored by pilot 15.In this control device 16, store the injection scheme (as shown in Figure 3) that jet path should be followed.Compare with the injection scheme of being stored in the arteries and veins that in control device 16, will record with limit switch 11,12.
On alternating current generator 7,9, respectively be provided with a group relay 17, be used to make mandrel 6,8 forward or reverse.Relay 17 is connected with control device 16 by pilot 15.Be provided with a frequency adjuster 18 in addition, it is connected with relay 17 and control device 16.
After the automatic starter structure was released, this figure was begun by reference point PO, so that with displacement measurement system zero setting.The arrival of reference point PO will provide signal along X and Y direction by limit switch 13,14.Subsequently, enter starting point PS.When arriving starting point PS, ejection medium is input in the carbon black remover, begins to carry out injection scheme thus.At this moment, count pulse that limit switch 11,12 records as the measured value (measured value) of level and vertical direction displacement and in control device with injection scheme on predetermined value (rated value) compare.If measured value is identical with rated value, then satisfies displacement condition, thereby enter next displaced segments.If depart from injection scheme, then stop to carry ejection medium and entering a PR that stops.
If will change the action time of jetting stream, can change the rotating speed of alternating current generator 7,9 by frequency regulator 18.Because what limit switch 11,12 detected is that displacement and its work do not rely on the speed that departs from injection scheme, thereby change the execution that rotating speed can not influence injection scheme.
Above-mentioned control device on being used in the carbon black remover, also can be used on other is on the device of feature with the long elements that is supported on two universal joints.
