Abstract
Disclosed is a multistory structure of a kiln liner for a cylindrical rotary heat device. The kiln liner is of the multistory structure, and comprises an isolation layer, a thermal insulation layer and a work layer, which are closely adjacent in sequence, wherein the isolation layer is arranged on the inner wall of the rotary heat device, the surface of the work layer is a work surface contacted with materials, the isolation layer and the thermal insulation layer are respectively formed by installing and fixing sheet thermal insulation and isolation materials stable in size, and the thicknesses of the isolation layer and the thermal insulation layer respectively do not exceed 1/10 of the thickness of the work layer. According to the multistory structure of the kiln liner for the cylindrical rotary heat device, the kiln liner is set to be in the multistory structure formed by the isolation layer, the thermal insulation layer and the work layer, and accordingly heat efficiency of the cylindrical rotary heat device is improved on the premise that integral strength of the kiln liner is not destroyed, the problems that a housing and the work layer are damaged caused by collision of the work layer and the housing of the cylindrical rotary heat device during the rotation process of the work layer after the kiln liner looses are avoided due to the multistory structure, and furthermore use life of the kiln liner and the cylindrical rotary heat device is prolonged.
Description
Technical field
The utility model relates to the kiln lining of using in the hot equipment of revolution, and a kind of cylindrical shape is turned round the multilayer kiln lining structure that hot equipment is used specifically.
Background technology
In the heating field of various industries, be widely applied to the revolution firing equipment that installs kiln lining in cylindrical shape box hat inside additional, also claim rotary kiln, rotary dryer, rotary calciner, rotary calcining stove etc.The hot equipment kiln lining of traditional revolution adopts wedge shape building block to build by laying bricks or stones along inwall, stablizes kiln lining by the lateral pressure of wedge-shaped surface, once certain is damaged, the cavity of generation has just destroyed the mechanics rock-steady structure of this part kiln lining, and kiln lining is at once lax.Because equipment is operated in gyration state always, make like this kiln lining in operation process, to collide with the inwall of hot equipment, not only can cause damage to the shell of hot equipment, and greatly reduce the service life of kiln lining.
In addition,, because kiln lining lax also can be caused scattering and disappearing of heat in kiln, reduced the thermal efficiency of equipment.
Utility model content
Turn round the kiln lining of hot equipment and can be in operation process after lax cause damage, life-span of kiln liner is low and the thermal efficiency is low problem with cover attack for solving cylindrical shape in prior art, the utility model provides a kind of cylindrical shape to turn round the multilayer kiln lining structure that hot equipment is used.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of cylindrical shape is turned round the multilayer kiln lining structure that hot equipment is used, described kiln lining is sandwich construction, comprise adjacent successively separation layer, heat-insulation layer and working lining, and separation layer is arranged on the inwall of the hot equipment of revolution, the surface of working lining is the working face contacting with material, described separation layer and heat-insulation layer adopt the thin slice insulation isolated material of volume stability that fixing formation is installed, and thickness is no more than 1/10 of working lining.
Described working lining adopts castable refractory to build and forms, and is distributed with blind hole on it.
Spacing on described working lining between blind hole is 0.2-0.35 rice.
The bottom of described blind hole extends to the bottom of working lining but does not penetrate working lining, and the degree of depth of each blind hole is incomplete same.
In the utility model, the shape of blind hole can have any shape, as triangle, circle or other shape; On working lining, the effect of blind hole is: in baker process; baker heat can reach rapidly working lining deep by these blind holes; working lining and separation layer and heat-insulation layer internal liquid expanding volume can extend to these blind holes; liquid in working lining and separation layer and heat-insulation layer and moisture are subject to thermogenetic hot kinetic potential and steam to overflow and make kiln lining release along blind hole to surface, and protection kiln lining is not torn damage by the inner bulbs of pressure.
Beneficial effect: the utility model is by being arranged to kiln lining the sandwich construction of separation layer, heat-insulation layer and working lining, thereby play the thermal efficiency that improves equipment under the prerequisite of not destroying kiln lining bulk strength, the setting of sandwich construction also can prevent the problem that after kiln lining is loosening, working lining is impaired with the shell that the collision of device housings causes in rotation process, working lining damages, and has improved service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Reference numeral: 1, separation layer, 2, heat-insulation layer, 3, working lining, 301, working face, 302, blind hole 4, inwall.
The specific embodiment
As shown in the figure, a kind of cylindrical shape is turned round the multilayer kiln lining structure that hot equipment is used, described kiln lining is sandwich construction, comprise adjacent successively separation layer 1, heat-insulation layer 2 and working lining 3, and separation layer 1 is arranged on the inwall 4 of the hot equipment of revolution, the surface of working lining 3 is the working face 301 contacting with material, and described separation layer 1 and heat-insulation layer 2 adopt the thin slice insulation isolated material of volume stability that fixing formation is installed, and thickness is no more than 1/10 of working lining 3.
The thickness of above-mentioned separation layer 1 and heat-insulation layer 2 is no more than 1/10 of working lining 3, refers to that the thickness of separation layer 1 and heat-insulation layer 2 is all no more than 1/10 of working lining 3 thickness:
Be more than basic embodiment of the present utility model, can on above basis, be improved further or limit:
As, described working lining 3 adopts castable refractory to build and forms, be distributed with blind hole 302 on it, and the shape of blind hole 302 is any, as triangle, circle or other shape;
The spacing that blind hole is 302 is 0.2-0.35 rice;
The bottom of blind hole 302 extends to the bottom of working lining 3 but does not penetrate working lining 3, and the degree of depth of each blind hole 302 is incomplete same.
