The embodiment of the present invention is introduced in order to clearer, is introduced from the application method of the embodiment of the present invention below.
Before repairing 11 damaged part of coking chamber wall, pusher machine is moved to and needs to repair by carbonizing chamber, pushes away sky carbonization chamber,
Not upper furnace door 9.Solid-state high temperature resistant amorphous refractory is prepared and stirred evenly in proportion with liquid adhesive, its stream is made
The indices such as dynamic property, dilatancy, the bridging time of high temperature gunning refractory, high volume stability and mobility, which meet spray repair, to be wanted
It asks.Control curing time of the high temperature gunning refractory under 1000 DEG C of -1200 DEG C of high temperature, it is ensured that the uniformity of stream.Start leveling bar 2
And motor, motor drive the first scalable horizontal cantilever 3-1 to act in sliding slot 2-1, scan carbonization chamber using high temperature imager 4
The damaged position 12 of furnace wall 11.According to the information that high temperature imager 4 is fed back, determine damage location and size, programmable controller 8 to
Leveling bar 2, the first scalable horizontal cantilever 3-1, the scalable vertical scalable horizontal cantilever 3-3 of cantilever 3-2 and second send dynamic
Make signal, mobile leveling bar 2, the first scalable horizontal cantilever 3-1, the scalable vertical scalable transverse direction of cantilever 3-2 and second are outstanding
Arm 3-3 makes the second scalable horizontal cantilever 3-3 be accurately positioned at damaged position 12.Programmable logic controller (PLC) 8 is sent to air compressor machine
Signal is purged, air compressor machine is started, air compressor machine conveys cold air by scavenging conduit 6-1, purges damaged position 12 by blasting cold air.
After purging, programmable logic controller (PLC) 8 sends rotating signal to rotating electric machine, and rotating electric machine rotates sealing plate 5, makes its abutting
Carbonizing chamber furnace wall 11, it is ensured that do not spilt over when spray repair mud.Sealing plate 5, which is one piece, can cover furnace wall and turn round the rectangle iron plate at position, peace
Front end loaded on the second lateral telescopic boom 3-3, and 90 ° of rotations can be done.Spray head front end, the front end scavenging conduit 6-1 and sealing plate are solid
It is scheduled on together, the front end and jet pipe front end of scavenging conduit 6-1 is at an angle of 90.Three, which synchronizes to do, to rotate, i.e., when 4 operation of high temperature imager
When, sealing plate 5 is in level, and the front end of scavenging conduit 6-1 is in level, and when needing spray repair operation, sealing plate 5 is rotated by 90 °, and is close to furnace wall
11, scavenging conduit 6-1, which are rotated to top, to be stopped purging, and interference is avoided to spray.Refractory wass stirs in rotary feeder 7-1
Even, under 1000 DEG C of -1200 DEG C of high temperature, the cold air of air compressor machine enters rotary feeder 7-1 by compressed air pipe 7-3
It is interior, high temperature resistant mud is delivered to spray head by being blown mud hose 7-3, blowing mud hose 7-3 is double-layer hose, outer laminar flow
Dynamic cooling water, internal layer convey refractory wass, avoid causing refractory wass to solidify since conveying distance is too long, and spray head is by refractory wass
Wall damaged part is sprayed into send out pressure signal after the pressure sensor on sealing plate 5 is reached certain numerical value by mud pressure
Programmable logic controller (PLC) 8 is given, programmable logic controller (PLC) 8 sends stop signal to rotary feeder 7-1, stop spray repair,
Mud valve 7-4 setting is on blowing mud hose 7-3, for adjusting the flow of refractory wass.Continue to seal after the completion of spray repair
Plate 5 is held against furnace wall 11, removes after mud molding.Sealing plate 5 is rotated, not interfere high temperature imager 4 to scan.Utilize high temperature
Imager 4 check spray repair effect, it is necessary to when can carry out it is secondary fill spray, can replace be manually entered carbonization chamber high-temperature reparation operation,
Labor intensity effectively is alleviated, ensure that production safety, is handled without cooling, the repairing time is both shortened, it is ensured that production
Rhythm in turn ensures the longevity for being conducive to carbonization chamber wall.Meanwhile arc guide barrel can be set on leveling bar 5, by arc guide barrel
10 are installed on 2 front end of leveling bar, which can make the first scalable horizontal cantilever 3-1 rotate horizontally 180 °, and covering is left
Right all positions of two sides carbonizing chamber furnace wall can do spray repair to all damaged parts, so that carbonizing chamber two sides furnace wall is able to achieve
Line spray repair is saved the time, is improved efficiency.
It should be noted last that the above specific embodiment is only used to illustrate the technical scheme of the present invention and not to limit it,
Although being described the invention in detail referring to example, those skilled in the art should understand that, it can be to the present invention
Technical solution be modified or replaced equivalently, without departing from the spirit and scope of the technical solution of the present invention, should all cover
In the scope of the claims of the present invention.
