Introduce the embodiment of the present invention in order to clearer, introduced from the using method of the embodiment of the present invention below.
Before repairing coking chamber wall 11 damaged part, move to pusher machine need to repair by carbonizing chamber, push away sky carbonization chamber,
Not upper furnace door 9.High temperature resistant for solid-state amorphous refractory is prepared in proportion with liquid adhesive and stirs so that it is stream
The indices such as dynamic property, dilatancy, the bridging time of high temperature gunning refractory, high volume stability and mobility meet spray repair to be wanted
Ask.Control high temperature gunning refractory hardening time 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, driven by motor first scalable horizontal cantilever 3-1 action in chute 2-1, utilize high temperature video camera 4 to scan carbonization chamber
The damaged position 12 of furnace wall 11.According to high temperature video camera 4 feedack, determine damage location and size, Programmable Logic Controller 8 to
Leveling bar the 2, first scalable horizontal cantilever 3-1, scalable vertical cantilever 3-2 and the second scalable horizontal cantilever 3-3 send dynamic
Make signal, mobile leveling bar the 2, first scalable horizontal cantilever 3-1, scalable vertical cantilever 3-2 and second scalable the most outstanding
Arm 3-3, makes the second scalable horizontal cantilever 3-3 be accurately positioned at damaged position 12.Programmable logic controller (PLC) 8 sends to air compressor machine
Purging signal, starts air compressor machine, and air compressor machine carries cold air by scavenging conduit 6-1, by blasting the damaged position 12 of cold air purging.
After purging, programmable logic controller (PLC) 8 sends rotating signal to electric rotating machine, and electric rotating machine rotates shrouding 5 so that it is be close to
Carbonizing chamber furnace wall 11, it is ensured that do not spill over during spray repair mud.Shrouding 5 is one piece and can cover furnace wall and turn round the rectangle iron plate at position, peace
It is loaded on the front end of the second horizontal telescopic boom 3-3, and 90 ° of rotations can be done.Shower nozzle front end, scavenging conduit 6-1 front end are with shrouding admittedly
Being scheduled on together, the front end of scavenging conduit 6-1 is with jet pipe front end at an angle of 90.Three synchronizes to do to rotate, i.e. when high temperature imager 4 operation
Time, shrouding 5 is in level, and the front end of scavenging conduit 6-1 is level, when needs spray repair operation, and shrouding 5 half-twist, it is close to furnace wall
11, scavenging conduit 6-1 rotate to top and stop purging, it is to avoid interference spraying.Refractory wass stirs all 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 piping 7-3
In, high temperature resistant mud is delivered to shower nozzle by winding-up mud hose 7-3, winding-up mud hose 7-3 is double-layer hose, outer laminar flow
Dynamic cooling water, internal layer conveying refractory wass, it is to avoid causing refractory wass to solidify owing to fed distance is long, shower nozzle is by refractory wass
Spray into body of wall damaged part, after the pressure transducer on shrouding 5 is reached certain numerical value by mud pressure, pressure signal is sent out
Giving programmable logic controller (PLC) 8, programmable logic controller (PLC) 8 sends to rotary feeder 7-1 and stops signal, stops spray repair,
Mud valve 7-4 is arranged on winding-up mud hose 7-3, for adjusting the flow of refractory wass.Spray repair continues after completing will envelope
Plate 5 is held against furnace wall 11, removes after mud molding.Rotate shrouding 5, not hinder high temperature video camera 4 to scan.Utilize high temperature
Video camera 4 checks spray repair effect, it is necessary to time can carry out secondary and fill spray, can replace being manually entered carbonization chamber high-temperature reparation operation,
Effectively alleviate labor intensity, it is ensured that production safety, process of need not lowering the temperature, both shortened the repairing time, it is ensured that produce
Rhythm, in turn ensure that the longevity of beneficially carbonization chamber body of wall.Meanwhile, arc guide barrel can be set on leveling bar 5, by arc guide barrel
10 are installed on leveling bar 2 front end, and this arc guide barrel 10 can make the first scalable horizontal cantilever 3-1 horizontally rotate 180 °, covers a left side
All damaged parts can be done spray repair by all positions of carbonizing chamber furnace wall, right both sides so that carbonizing chamber both sides furnace wall all can realize
Line spray repair, saves the time, improves efficiency.
It should be noted last that, above detailed description of the invention only in order to technical scheme to be described and unrestricted,
Although the present invention being described in detail with reference to example, it will be understood by those within the art that, can be to the present invention
Technical scheme modify or equivalent, without deviating from the spirit and scope of technical solution of the present invention, it all should be contained
