Description
Technical field
The utility model relates to dangerous waste incineration technical field more particularly to a kind of rotary kiln composite bricks.
Background technique
In the prior art, between dangerous waste incineration rotary kiln and cylinder of rotary kiln, refractory brick and guarantor are generally equipped with
Two layers of brick laying structure of warm brick.Wherein, refractory brick is laid on the surface layer of rotary kiln, can directly with dangerous waste incineration face contact
Bear high temperature；Insulating brick is laid between refractory brick and cylinder of rotary kiln, plays thermal insulation function, is effectively completely cut off in rotary kiln
Influence of the high temperature to cylinder of rotary kiln and environment.
But in practice, it often due to insulating brick is different with high-temperature shrinkage rate with the density of refractory brick, is opening kiln and is stopping
Due to expanding with heat and contract with cold during kiln, it is easy to generate gap between two layers of brick body, cause to occur between insulating brick and refractory brick
It peels off, and since insulating brick intensity is not so good as refractory brick, in use, insulating brick is easily worn, and ultimately causes refractory brick
Total collapse.
How to increase the service life of insulating brick and refractory brick, and then save cost, is that the technology of current urgent need to resolve is asked
Topic.
Summary of the invention
In view of this, the utility model proposes a kind of rotary kiln composite brick, to solve technology existing in the prior art
Defect.
In order to achieve the above objectives, the technical solution of the utility model embodiment is achieved in that
The utility model discloses a kind of rotary kiln composite bricks, between rotary kiln and cylinder of rotary kiln, comprising:
Integrally formed fire brick layer and insulating brick-layer, the fire brick layer and the insulating brick-layer are along from rotary kiln to returning
The direction arranged of rotary kiln cylinder, and be fixedly connected between the fire brick layer and the insulating brick-layer.
Optionally, the insulating brick-layer is embedded with light layer close to the side of the cylinder of rotary kiln.
Optionally, it is fitted between the fire brick layer and the insulating brick-layer for waveform affixed.
Optionally, the width of the width of the fire brick layer and the insulating brick-layer is along from cylinder of rotary kiln to rotary kiln
Direction it is tapered.
Optionally, the length of the fire brick layer accounts for the 65%~75% of the length of the rotary kiln composite brick.
The rotary kiln composite brick of the utility model, by the way that fire brick layer and insulating brick-layer is integrally formed, with existing skill
Art is compared, and is effectively prevented the risk that refractory brick collapses, is extended the service life of refractory brick, and it is difficult to reduce construction
Degree, has saved operating cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the rotary kiln composite brick of the utility model embodiment；
Fig. 2 is the sectional view of the rotary kiln composite brick of the utility model embodiment.
Appended drawing reference
10-rotary kiln composite bricks；11-fire brick layers；12-insulating brick-layers；13-light layers.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below by way of specific embodiment
And referring to attached drawing, the utility model is described in detail.
The shorter technological deficiency of service life in order to solve insulating brick and refractory brick existing in the prior art, this is practical
New embodiment discloses a kind of rotary kiln composite brick and has saved operating cost to extend the service life of refractory brick.
To achieve the goals above, the structure of the rotary kiln of the present embodiment composite brick 10 is referring to Fig. 1 and Fig. 2, comprising: one
The fire brick layer 11 and insulating brick-layer 12 of body forming, fire brick layer 11 and insulating brick-layer 12 are along from rotary kiln to cylinder of rotary kiln
Direction arranged, and be fixedly connected between fire brick layer 11 and insulating brick-layer 12.
Wherein, it there are many fixed connection modes between fire brick layer 11 and insulating brick-layer 12, such as is bonded, is spirally connected, this implementation
In example, fire brick layer 11 and insulating brick-layer 12 are just integrally formed in initial manufacture, and the fixed connection mode between the two is to fire
Connection, to save process and cost.
More at large, affixed between fire brick layer 11 and insulating brick-layer 12 is not fitted and connected for two planes, and
Be be fitted into for waveform it is affixed, referring to fig. 2, make combine it is even closer, it is not easily to fall off.
Also, since rotary kiln is cylindrical structure, the rotary kiln in the present embodiment when in use, is needed with composite brick 10
Circlewise arranged is in the side of rotary kiln, then, the width (i.e. perpendicular to the size in the direction D1 in Fig. 2) of fire brick layer 11
It is tapered with width direction (i.e. D1 direction in Fig. 2) of the edge from cylinder of rotary kiln to rotary kiln of insulating brick-layer 12.
In addition, when practical application, it is contemplated that the complexity and strong corrosive of flue gas during dangerous waste incineration, and fire resisting
The flue gas that brick layer 11 directly burns generation with hazardous waste directly contacts, so fire brick layer 11 should have strong corrosion resistant, and resistance to
The length (i.e. along the size in the direction D1) of firebrick layer 11 accounts for the 65%~75% of the length of entire rotary kiln composite brick 10.
Optionally, in order to guarantee the surface temperature of kiln body, insulating brick-layer 12 is embedded with gently close to the side of cylinder of rotary kiln
Matter layer 13.Light layer 13 (such as rock wool) should have better heat insulation effect compared to insulating brick-layer 12.
In conclusion the rotary kiln composite brick in the present embodiment can replace refractory brick in the prior art and guarantor completely
Two layers of brick laying structure of warm brick, brick body is once-forming, effectively prevents the risk that refractory brick in the prior art collapses, significantly
The service life for extending refractory brick, has saved operating cost, ensure that stability (two layers brick body in the prior art of system
Service life is generally 1 year or so, no longer than 3 years；The service life of composite brick described in the present embodiment is up to 5 years).Together
When, for the building construction of two layers of brick body, the building construction difficulty of one layer of brick body is substantially reduced, reduce construction volume,
Construction efficiency is improved, operating cost has been saved.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution, improvement and etc. done should be included in the utility model
Within the scope of protection.
