Abstract
The utility model discloses a fireproof brick and particularly relates to an embedded type silicon mullite brick for a cement kiln, which comprises a brick body (1). A square groove (2) is arranged at one end of the brick body, which is far away from a work surface (3); and a light temperature-preserving brick (4) is bound into the square groove (2) by a high-temperature binder. The heat conductivity of the silicon mullite brick can be reduced, and the silicon mullite brick can be guaranteed to have the intensity for resisting shear stress when being used.
Description
Technical field
The utility model belongs to the refractory brick field, specifically is the inserted siliceous mullite brick of a kind of cement kiln.
Background technology
Cement kiln uses the intermediate zone of position as cement kiln Dayao kiln body with siliceous mullite brick now, because cement kiln Dayao kiln body is to be in for a long time under the dynamical state of rotation in operation process, and also can rotate as the refractory material of kiln body liner thereupon, corresponding meeting is subjected to the effect of shear stress, so kiln body liner can only adopt the phenomenon of individual layer liner, consider that material internally is lined with wearing and tearing in the cement burning process, bump and the phenomenon that corrodes, selecting for use of refractory material is the fire-resistant molded article of heavy, but the fire-resistant molded article thermal conductivity of heavy is up to 2.5-3.0W/mK, thereby caused the heat of kiln in operation process to lose greatly, waste a large amount of energy, reduced the efficient of kiln.
The utility model content
At the above, the utility model aims to provide and a kind ofly can reduce thermal energy consumption, the opposing strong cement kiln of shear stress inserted siliceous mullite brick.
For achieving the above object, the inserted siliceous mullite brick of a kind of cement kiln of the present utility model comprises the brick body, away from working face one end a square groove is set at described brick body, with high-temperature agglomerant light-weight insulating brick is bonded in the described square groove.
The height of described square groove is 50mm, and width is 80mm.The length of square groove and the equal in length of siliceous mullite brick.
Described brick body, its single brick height is 220mm, width is 198mm.
The size of described light-weight insulating brick equates with the size of described square groove.
Adopt the inserted siliceous mullite brick of this programme cement kiln, because of siliceous mullite brick height commonly used is 220mm, width is 198mm, and the light-weight insulating brick that is inlaid into is of a size of 50mm*80mm, the volume of the light-weight insulating brick that is inlaid into accounts for about 10% of whole brick body volume, and is less to the influence of brick body bulk strength; Because of the light-weight insulating brick heat transfer area that is inlaid into accounts for 40% of total heat conduction area, the thermal conductivity of the anti-insulating brick of lightweight all is lower than 0.5W/mK again, and the thermal conductivity of siliceous mullite brick is between 2.5-3.0W/mK, so heat loss rate can reduce about 40%.Consumed energy is low, the strong technique effect of opposing shear stress so employing cement kiln of the present utility model has with inserted siliceous mullite brick.
Description of drawings
Fig. 1 is that locations of structures of the present utility model concerns schematic diagram.
The specific embodiment
As shown in Figure 1, the inserted siliceous mullite brick of a kind of cement kiln of the present utility model comprises brick body 1, away from working face 3 one ends a square groove 2 is set at described brick body, bonds in the described square groove 2 with the light-weight insulating brick 4 of high-temperature agglomerant with suitable dimension.
Described brick body 1 highly is 220mm, and width is 198mm, and the height of described square groove (2) is 50mm, and width is 80mm, and the size of described light-weight insulating brick 4 equates with the size of described square groove.Cement kiln is with the indefinite length of siliceous mullite brick now, but its height one is 220mm, width is 198mm, such size helps the global design and the stability of cement kiln body, but because siliceous mullite brick all is that the heavy refractory material is made, its thermal conductivity coefficient is big, cause thermal loss very big, so under the prerequisite that does not influence the cement kiln monolithic stability, the square groove of a size regulation is set on every siliceous mullite brick, and the insulating brick 4 that will utilize the low lightweight refracrory of thermal conductivity factor to make then is filled into to be reserved in the square groove.A large amount of practices show that the height of square groove 2 is 50mm, and width can reach kiln body intensity effect minimum during for 80mm, and whole kiln body heat energy loss is minimum.
Claims (4)
1. the inserted siliceous mullite brick of cement kiln comprises brick body (1), it is characterized in that: away from working face (3) one ends a square groove (2) is set at described brick body, with high-temperature agglomerant light-weight insulating brick (4) is bonded in the described square groove (2).
2. according to the inserted siliceous mullite brick of the described cement kiln of claim 1, it is characterized in that: the height of described square groove (2) is 50mm, and width is 80mm.
3. according to the inserted siliceous mullite brick of the described cement kiln of claim 1, it is characterized in that: described brick body (1) highly is 220mm, and width is 198mm.
4. according to the inserted siliceous mullite brick of the described cement kiln of claim 1, it is characterized in that: the size of described light-weight insulating brick (4) equates with the size of described square groove (2).
