Slag tube body 110 has the first end 111 for being fixedly connected and being connected to fluidized bed furnace (not shown), and (figure is not with chilling roll
Show) second end 112 that is fixedly connected and is connected to.The first default side is set as along the direction of first end 111 towards second end 112
To.
In the present embodiment, deslagging tube body 110 includes fixing pipe 113 and adjustable pipe 114.Wherein, the one of fixing pipe 113
End is welded to connect and is connected to fluidized bed furnace, and specifically, fixing pipe 113 is welded on the bottom of boiling furnace slag discharge overflow port；Fixing pipe
113 other end is connected to and in communication with 114 socket joint of adjustable pipe；The one end of adjustable pipe 114 far from fixing pipe 113 and chilling roll are solid
Surely it is connected to and in communication with, specifically, adjustable pipe 114 is welded to connect in the center of chilling roll import.
It should be noted that in the present embodiment, the socket joint connection type of fixing pipe 113 and adjustable pipe 114 is not made specifically
Limitation, further, deslagging tube body 110 further includes bell and spigot joint 115.Adjustable pipe 114 has far from one end of chilling roll
First charging aperture 116 for being connected to and in communication with bell and spigot joint 115.Along the first preset direction, one end of bell and spigot joint 115 has
There is second charging aperture 117, the other end has discharge port 118.Along the first preset direction, the section of fixing pipe 113 is in circular ring shape.The
The bore of two feed inlets 117 is greater than the outer diameter of fixing pipe 113, and the bore of discharge port 118 is equal to the bore of second charging aperture 117.
In the present embodiment, inner wall (being not marked in figure) bonding of second charging aperture 117 is provided with elastic component 119.Outside fixing pipe 113
Wall (being not marked in figure) is abutted with the formation of elastic component 119.
According to the connection type of above-mentioned fixing pipe 113 and adjustable pipe 114, if 100 expanded by heating of scum pipe, it can held
Free extension at interface will not influence the normal rotation of chilling roll.
It should be noted that in the present embodiment, the pipe range ratio of fixing pipe 113 and adjustable pipe 114 is 3:30-35.Root
According to the structure of above-mentioned deslagging tube body 110, since the length of fixing pipe 113 is far smaller than adjustable pipe 114, fixing pipe 113
It is unlikely to deform when heated.
In the present embodiment, cooling water pipe 120 is sheathed on deslagging tube body 110.Cooling water pipe 120 and scum pipe sheet
The specific connection type of body 110 is not particularly limited, and further, edge is parallel to the first preset direction, cooling water pipe 120
With the third end 121 and the 4th end 122 being oppositely arranged.Third end 121 and the 4th end 122 are welded with the outer wall of adjustable pipe 114
It connects in succession.Wherein, third end 121 is arranged close to fluidized bed furnace；4th end 122 is arranged close to chilling roll.Deslagging tube body 110
The cold water gap 123 for accommodating cooling water is formed between outer wall and the inner wall of cooling water pipe 120.Cooling water pipe 120
It is provided with and is conducive to be passed through cooling water and cool down to adjustable pipe 114, and then the service life of scum pipe 100 can be extended, change simultaneously
Kind 100 dilatancy phenomenon of scum pipe.
It should be noted that in the present embodiment, cooling water pipe 120 offers water inlet 124 and water outlet 125.Its
In, water inlet 124 is arranged close to third end 121, and water outlet 125 is arranged close to the 4th end 122.Above-mentioned set-up mode be conducive into
The cooling cooling water circulation of row.
In the present embodiment, the direction of the outer wall of deslagging tube body 110 towards the outer wall of cooling water pipe 120 is set as
Two preset directions.The side wall of cooling water pipe 120 is convexly equipped at least one telescopic expansion joint 130 along the second preset direction.
Due to although the thermal expansion of scum pipe 100 can be reduced, will appear interior after adding cooling water pipe 120
Outer excessive temperature differentials easily leads to 120 breach of cooling water pipe.Therefore, telescopic expansion joint 130 is added on cooling water pipe 120, with
Make cooling water pipe 120 can be with 100 free extension of scum pipe.
The structure of telescopic expansion joint 130 is not particularly limited, in the present embodiment, further, along pre- perpendicular to first
Set direction, the section of cooling water pipe 120 are in circular ring shape, and the section of telescopic expansion joint 130 is in circular ring shape.So that cooling water pipe
120 even inflations.
Fluidized bed furnace scum pipe 100 provided in this embodiment works in this way: waste residue enters fixing pipe 113 by fluidized bed furnace and passes through
Adjustable pipe 114 enters chilling roll.In the process, due to fixing pipe 113 with adjustable pipe 114 in such a way that socket joint is connect,
So that scum pipe 100 generated by waste residue heat when can at bell socket free extension, will not influence chilling roll just
Often rotation；Since the length of adjustable pipe 114 is much larger than the length of fixing pipe 113, it can be ensured that fixing pipe 113 is not variable when being heated
Shape；Since cooling water pipe 120 is sheathed on adjustable pipe 114, cooling water can cool down to adjustable pipe 114, to extend deslagging
The service life of pipe 100 improves 100 dilatancy phenomenon of scum pipe；It is set to the telescopic expansion joint 130 of cooling water pipe 120,
Cooling water pipe 120 can be made to carry out free extension with adjustable pipe 114, avoid the occurrence of breach.
In conclusion fluidized bed furnace scum pipe 100 provided in this embodiment, it is swollen which can improve scum pipe 100
The phenomenon that bulging deformation, extends the service life of scum pipe 100.
Embodiments described above is the utility model a part of the embodiment, instead of all the embodiments.
The detailed description of the embodiments of the present invention is not intended to limit the range of claimed invention, and
It is the selected embodiment for being merely representative of the utility model.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, fall within the protection scope of the utility model.
