Description
Technical field
It is specifically a kind of to turn round hot equipment hanging type furnace lining knot the present invention relates to the furnace lining turned round in hot equipment
Structure.
Background technology
In the heating art of various industries, the revolution heating for being widely applied to install additional kiln lining inside cylindrical shape box hat is set
It is standby, also referred to as rotary kiln, rotary dryer, rotary calciner, rotary calcining stove etc..The hot equipment furnace lining of traditional revolution uses wedge
Shape building block is built by laying bricks or stones along inwall, is that the separation of independent different objects reclines relation between outer steel shell and kiln brick, by the circle of outer steel shell
The stable furnace lining of the lateral pressure and frictional force of wedge-shaped surface between section and wedge-shaped kiln brick, furnace lining are covered with space along around kiln brick and claimed
For brickwork joint.Brick furnace lining belongs to movable furnace lining, and brick is constantly carried out in rotary kiln running and is squeezed with the mutual of brick, brick and outer steel shell
Pressure and head-on collision, once certain is damaged, caused cavity just destroys the mechanics rock-steady structure of this part furnace lining, and furnace lining is at once loose
Relax.Because equipment always works at gyration state, so that the inwall that furnace lining can be with hot equipment in operation process touches
Hit, not only the shell of hot equipment can be caused to damage, and be greatly reduced the service life of furnace lining.
The content of the invention
To solve existing hot equipment furnace lining in the process of running because local damage produces relaxation and then causes to set with heat
The problem of shell damages, lining durability is low caused by standby inwall collision, the invention provides one kind to turn round hot equipment hanging type stove
Lining structure, in order to avoid extrusion and collision damage occurs for the high-strength furnace lining overall in rotary kiln running and overall high-strength outer steel shell
It is bad, therefore be specifically designed to be provided with flexible multilayer structure between working lining furnace lining and outer steel shell, the furnace lining structure is in construction
For Multilayer compact structure, the caving in caused by insufficient strength when initial will not occur due to furnace lining, in hot equipment running process
In, due to turning round the effect of the huge moment of torsion and high temperature gas flow of gravitational moment in kiln, making flexible layer, efflorescence formation powder is suitable quickly
Outside outer steel shell inwall export kiln, the position of flexible layer forms cavity interlayer, makes to have been provided with the working lining furnace lining of very high intensity
By the anchoring strength of anchoring piece vacantly in the outer box hat of hot equipment, the anchor when furnace lining that worked in rotary kiln running is in bottom
Gu system furnace lining is produced it is upward lift power, anchor system is to furnace lining when the furnace lining that worked when rotary kiln running is in topmost
Upward traction force is produced, due to there is a layer of air interlayer between working lining furnace lining and outer steel shell, equivalent to bulky furnace lining quilt
Entirely vacantly hang on outer steel shell, avoid the collision of working lining furnace lining and outer box hat, greatly extend the service life of furnace lining.
The present invention is that technical scheme is used by solving above-mentioned technical problem：One kind turns round hot equipment hanging type furnace lining knot
Structure, including outer box hat and the working lining furnace lining that is anchored at by anchoring piece in outer box hat, the outer box hat and working lining furnace lining it
Between be disposed with the compressible efflorescence layer of cohesive powders last layer, thin slice and high-strength mucilage layer, wherein, cohesive powders last layer is close to outer steel
The surface of shell, and the compressible efflorescence layer of thin slice is adhered on outer box hat, high-strength mucilage layer and working lining furnace lining is combined closely shape
Into containment vessel, and containment vessel efflorescence layer compressible with thin slice is formed and is bonded, and the cohesive powders last layer is by with viscosity and without solid
The powder filling of setting state forms, and the compressible efflorescence layer of thin slice is made up of the laminar compressible material with stable topography,
So that in turning course, cohesive powders last layer and the compressible efflorescence layer of thin slice are after powdered in the presence of turning round gravitational moment by outer steel
Shell exports, so as to form air blanketing between high-strength mucilage layer and outer box hat.
The cohesive powders last layer is formed by the filling of coal tar, pitch or clay powder.
The compressible efflorescence layer of thin slice is by asbestos board, rock cotton board, sepiolite plate, aluminosilicate fiberboard or calcium silicate board with microporous system
Into.
The thickness of the cohesive powders last layer is no more than 5mm.
The thickness of the compressible efflorescence layer of thin slice is 5-15mm.
The thickness of the high-strength mucilage layer is 2-5mm.
Beneficial effect：The present invention compared with prior art, has advantages below：
1）The present invention between outer box hat and working lining furnace lining by setting gradually cohesive powders last layer, the compressible efflorescence of thin slice
Layer and high-strength mucilage layer so that working lining furnace lining pour or building process in can rely on this three layers and constructed,
Furnace lining working lining is prevented produce damaged or crackle due to intensity deficiency after firm construction the defects of；
2）In the present invention, cohesive powders last layer uses without intensity, has viscosity, the organic or inorganic cohesive powders without solid form
End filling is formed, and the compressible efflorescence layer of thin slice, which uses, to be had solid shape, have some strength, have certain compressibility, be easily damaged
The lamellar material stacking for losing intensity formation powder is formed, and the compressible efflorescence layer of thin slice is bonded in outer box hat by cohesive powders last layer
On, hot equipment is turned round in revolution is run, and due to turning round the effect of gravitational moment, cohesive powders last layer and the compressible efflorescence layer of thin slice exist
By unbalanced compression in running, it is deformed, fold, surface configuration and intensity are destroyed, then under revolution
Powder is crushed into rotation, these powder can export with the gyration for turning round hot equipment along outer steel shell, and then with continuous
Gyration forms cavity interlayer, so that working lining furnace lining supports fixation low suspension in outer steel shell in rigid anchoring piece
It is interior, contact, collision with outer steel shell are avoided, thermal shock resistance and the life-span of working lining furnace lining is greatly improved；
3）In the present invention, the strong mucilage layer of a floor height, high-strength mucilage layer and work are tightly wrapped in working lining furnace lining outer surface
Make layer furnace lining to combine closely, play a part of solidifying working lining furnace lining and isolation and protect working lining furnace lining, and high-strength mucilage
Layer combines to form complete containment vessel with working lining furnace lining surface, in order to when the compressible efflorescence layer of thin slice and cohesive powders last layer not
In the presence of, play protection working lining furnace lining, prevent working lining furnace lining surface from being contacted with outer steel shell, collide caused by lining durability drop
It is low.
