Description
Technical field
The utility model relates to the seal of rotary kiln structure technologies in coking technology field, more particularly to a kind of rotary kiln bullet
Property sealing structure.
Background technique
In metallurgical coking technical field, the sealing of rotary kiln end or kiln tail generally uses elastic sealing structure.Currently, often
There are two types of structures for rotary kiln elastic packing, and one is the outer wall that elastic packing plate one end is fixed on to seal closure, the other ends
Rotary kiln direction is stretched to, and is pressed on the sealing ring on rotary kiln, while opening elastic packing plate in kiln when positive pressure in order to prevent
So that dusty gas is leaked, needs tightly to be bundled in elastic packing plate on sealing ring with wirerope；Another kind is by elastic packing
Plate is fixed on the inner ring of seal closure, and the other end stretches to kiln hood or kiln tail direction, and is pressed on sealing ring, in this way when positive pressure in kiln
When, elastic packing plate will be pressed to sealing ring by gas pressure, and kiln gas is made not leak.In the first structure, elasticity is close
Sealing plate is all disposed within outside, replaces and install more convenient, but the friction between elastic packing plate and sealing ring is bigger, abrasion
Comparatively fast.Although second of structure sealing effect is preferable, elastic packing plate is arranged inside seal closure, after installation or abrasion more
Change inconvenience.
Therefore, need to develop it is a kind of not only can guarantee sealing effect, but also the sealing structure of installation and replacement can be facilitated.
Utility model content
To overcome prior art defect, the technical issues of the utility model solves, is to provide a kind of rotary kiln elastic packing knot
Structure is provided simultaneously with existing the advantages of there are two types of sealing structures, and structure is simple, and easy to implement, sealing effect is good, convenient for installation and maintenance.
In order to achieve the above object, the utility model is implemented with the following technical solutions:
A kind of rotary kiln elastic sealing structure, including seal closure, elastic packing plate, flange seat, bolt and regulator board, it is special
Sign is that the seal closure is fixed by bolt and kiln head cover or kiln hood, and flange seat is welded on cylinder of rotary kiln；The bullet
Property sealing plate one end is bolted on the outer wall of flange seat, and the other end is pressed on the inner wall of seal closure；The regulator board
It is arranged between elastic packing plate and flange seat.
The maximum outside diameter size of the flange seat is less than the internal diameter of seal closure, is arranged outside seal closure far from revolution
The side of kiln kiln head cover or kiln hood.
If the elastic packing plate is dry plate, along flange seat outer wall circumference it is a piece of pressing against it is a piece of it is mutual stacking be evenly arranged.
After the elastic packing plate is installed, the elastic packing plate leaked out between flange seat and seal closure is in outer convex
Structure.
The regulator board, which is being pressed against, to be mounted between flange seat and elastic packing plate, can be slid back and forth along elastic packing plate.
Compared with prior art, the utility model has the beneficial effects that
1) situation for spraying ash when positive pressure in kiln outward can be overcome, comparison original structure is more convenient for installing；
2) according to practical sealing effect, it can adjust the pressing force of each elastic packing plate by regulator board, sealing effect is good；
3) the utility model device is provided simultaneously with existing the advantages of there are two types of sealing structures, and structure is simple, easy to implement, sealing
Effect is good, convenient for installation and maintenance.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
As shown in Fig. 1-Fig. 3, the utility model relates to a kind of rotary kiln elastic sealing structure, including seal closure 2, elasticity
Sealing plate 3, flange seat 5, bolt 4 and regulator board 7, the seal closure 2 are fixed by bolt and kiln head cover 1 or kiln hood, flange
Seat 5 is welded on cylinder of rotary kiln 6；Described 3 one end of elastic packing plate is fixed on the outer wall of flange seat 5 by bolt 4, another
Side pressure is on the inner wall of seal closure 2；The regulator board 7 is arranged between elastic packing plate 3 and flange seat 5.
The maximum outside diameter size of the flange seat 5 is less than the internal diameter of seal closure 2, and setting is separate in 2 outside of seal closure
The side of rotary kiln head-shield 1 or kiln hood.
If the elastic packing plate 3 is dry plate, the uniform cloth of a piece of mutual stacking is being pressed against along the outer wall circumference of flange seat 5 is a piece of
It sets.
After the elastic packing plate 3 is installed, the elastic packing plate 3 leaked out between flange seat 5 and seal closure 2 is in evagination
There is certain bending after the installation of arcuate structure, i.e. elastic packing plate 3, elastic packing plate 5 can be made closely to paste and in seal closure 2
On wall, it is ensured that sealed reliable.
The regulator board 7, which is being pressed against, to be mounted between flange seat 5 and elastic packing plate 3, can be slided before and after elastic packing plate 3
It is dynamic, according to practical sealing effect, it can adjust the pressing force of each elastic packing plate 3 by regulator board 7, it is ensured that sealing effect is good
It is good.
When work, 3 one end of elastic packing plate is fixed on flange seat 5 by bolt 4, and the other end is overlayed in seal closure
On 2 inner wall, the method that centre leaks out has a degree of bending, it is possible to provide so that it is pressed in the pressure of the inner wall of seal closure 2, reaches
To the effect of sealing.When positive pressure in kiln, gas pressure can be pressed in elastic packing plate 3 is even closer on seal closure 2, make kiln
Interior gas will not leak.
In the course of work, when the damage of certain a piece of elastic packing plate 3, cylinder of rotary kiln 6 can be rotated, makes the elasticity of damage
The position that sealing plate 3 moves to convenient for operation.Simultaneously as flange seat 5 is located at the outside of seal closure 2, and elastic packing plate 3
In the outer ring of flange seat 5, disassembly and replacement elastic packing plate 3 are easily facilitated, saving of work and time is laborsaving.
In the course of work, when finding certain a piece of elastic packing plate 3 causing pressing force insufficient due to installing or wear etc.
When, it can make regulator board 7 mobile to 1 direction of kiln head cover by the methods of percussion, push up the inside to elastic packing plate 3, it can be more
Tight is pressed on seal closure 2, improves and ensures sealing effect (see Fig. 3).
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
