Technical field
The utility model belongs to technical field of refractory materials, specifically relates to a kind of preheater insulating brick.
Background technology
In dry-process cement rotary kiln is produced, preheater works in high-temperature hot-air, the invasion and attack of tape material hot blast and wearing and tearing.The thickness of preheater sidewall lining brick has impact to output and energy consumption, but if increase the thickness of lining brick, internal capacity lowers, otherwise if lining brick can be effectively thinning, then internal capacity increases, and can improve cement kiln output.And due to preheater operating temperature higher, problem that is wear-resisting and energy-saving heat preserving must be considered while loss of weight, now design a kind of brick structure, the heat-insulating property of laying bricks is improved, the thickness of brick body can be reduced, its good heat-insulating property can be ensured again, thus reach the effect of energy-conserving and environment-protective and raising cement kiln output.
Summary of the invention
Technical problem to be solved in the utility model is just to provide a kind of preheater insulating brick, can reduce the thickness of brick body, can ensure again its good heat-insulating property, thus reaches the effect of energy-conserving and environment-protective and raising cement kiln output.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of preheater insulating brick, comprises the brick body that circumference is built by laying bricks or stones, and described brick body inside is provided with axial insulation wind-tunnel, and the two ends of described brick body are provided with the arc surface cooperatively interacted.Owing to having set up insulation wind-tunnel, make brick have the effect of air thermal preservation when proof strength, reduced the thermal conductivity factor of brick, made the heat insulation effect of brick can reach 100cm and be equal to former brick 140cm.Arc surface is set at brick body two ends simultaneously, makes building by laying bricks or stones of brick more convenient, and between brick body adjacent when building by laying bricks or stones, there is interlocking effect, brick quantity can be reduced, reduce and build difficulty by laying bricks or stones.
Preferably, described brick body comprises heat-insulation layer and flame retardant coating, and described insulation wind-tunnel is arranged in heat-insulation layer.Heat-insulation layer and flame retardant coating can adopt general brick material, also can adopt composite by different demand, can meet use needs, also can reduce costs.
Preferably, the end face that described heat-insulation layer is combined with flame retardant coating is provided with several upper protruding blocks and upper groove, described flame retardant coating is provided with the end face that heat-insulation layer combines several respectively with upper protruding block and the corresponding low groove of upper groove and lower protruding block, the clamping corresponding to low groove of described upper protruding block, the clamping corresponding to lower protruding block of described upper groove.The bond strength of heat-insulation layer and flame retardant coating can be strengthened, under heat-insulation layer and flame retardant coating are heated uneven situation, upper protruding block and low groove and can slight deformation adjust between upper groove and lower protruding block, thus tearing appears in the faying face avoided between heat-insulation layer and flame retardant coating, extends the service life of insulating brick.
Preferably, described upper protruding block and upper concave groove space are every setting, and described low groove and lower protruding block interval are arranged.
Preferably, the upper surface of described brick body is provided with groove.The setting of groove makes to retain space between heat-insulation layer and building brick body, can carry out cross-ventilation, thus better dispel the heat by space.
A kind of preheater insulating brick of the present utility model, by setting up insulation wind-tunnel, brick is made to have the effect of air thermal preservation when proof strength, reduce the thermal conductivity factor of brick, make the heat insulation effect of brick can reach 100cm and be equal to former brick 140cm, the thickness of brick body can be reduced, its good heat-insulating property can be ensured again, thus reach the effect of energy-conserving and environment-protective and raising cement kiln output.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
