Siliceous mullite brick
Technical field
The present invention relates to a kind of siliceous mullite brick.
Background technology
Existing mainly by brick body, the refractory brick of a kind of sillimanite mullite material that before and after the groove that runs through both sides, brick body front and back at brick body top and brick body, the groove that is arranged in groove below of two sides forms is first at the groove of two blocks of refractory brick, to spread binding material respectively when mounted, then two refractory brick groove docking relative with groove are got up so that be mutually bonded together between two blocks of refractory brick, easily like this occur that binding material smears inhomogeneous problem, when the binding material smeared is too much, between two blocks of refractory brick, can produce larger gap, when binding material is very few, do not have cementation, so too much or very few service life that all can affect the kiln being assembled into.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of siliceous mullite brick, by the both sides at groove, drainage trough is set, binding material is filled into from drainage trough the region that between two siliceous mullite bricks, groove surrounds in the mode of filling, binding material loading is even, there will not be the too much or very few situation of binding material, bonding scope is wide, and between two siliceous mullite bricks, bonding firmly.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: siliceous mullite brick, comprise brick body, the top of described brick body is provided with the groove that runs through both sides, brick body front and back, before and after described brick body, two sides are equipped with groove below groove, in described groove, be provided with drainage plate, before and after described brick body, on two sides, in the left both sides of groove, be provided with the drainage trough of communication groove and brick body left surface, before and after described brick body, on two sides, at the right flank of groove, be also provided with the drainage trough of communication groove and brick body right flank, in the direction that the groove width of described drainage trough is extended to the other end in the one end being communicated with groove from it, reduce gradually, before and after described brick body, on two sides, below groove, be provided with the tortuous sheep intestines groove of communication groove, in the direction that described sheep intestines groove extends to the other end in the one end being communicated with groove from it, groove width reduces gradually, groove depth shoals gradually.
As preferably, described drainage plate is provided with the first projection at the position of the connectivity part over against groove and groove left side drainage trough, described drainage plate is provided with the second projection over against the position of the connectivity part of groove and groove right side drainage trough, the upside of described drainage plate has the 3rd projection, the downside of described drainage plate has the 4th projection, described drainage plate is in the first projection and the 3rd projection, the first projection and the 4th projection, the second projection and the 3rd projection, wall between the second projection and the 4th projection is cancave cambered surface, described the 4th projection is over against the connection position of the sheep intestines groove of groove and groove below.
As preferably, the downside wall of described groove forms horn mouth being communicated with in the close direction in position the downward-sloping connection position of groove and sheep intestines groove that makes gradually to groove and sheep intestines groove.
As preferably, four edges and corners round-corner transitions of described groove.
Beneficial effect:
The siliceous mullite brick that the present invention adopts technique scheme to provide, by the both sides at groove, drainage trough is set, binding material is filled into from drainage trough the region that between two siliceous mullite bricks, groove surrounds in the mode of filling, binding material loading is even, there will not be the too much or very few situation of binding material, bonding scope is wide, and between two siliceous mullite bricks, bonding firmly.

The specific embodiment
As illustrated in fig. 1 and 2, siliceous mullite brick, comprise brick body 1, the top of described brick body 1 is provided with the groove 2 that runs through both sides, brick body front and back, described brick body 1 two sides, front and back are equipped with groove 3 below groove 2, in described groove 3, be provided with drainage plate 4, on described brick body 1 two sides, front and back, in the left both sides of groove 3, be provided with the drainage trough 5 of communication groove 3 and brick body 1 left surface, on described brick body 1 two sides, front and back, at the right flank of groove 3, be also provided with the drainage trough 5 of communication groove 3 and brick body 1 right flank, in the direction that the groove width of described drainage trough 5 is extended to the other end in the one end being communicated with groove 3 from it, reduce gradually, on described brick body 1 two sides, front and back, below groove 3, be provided with the tortuous sheep intestines groove 6 of communication groove 3, in the direction that described sheep intestines groove 6 extends to the other end in the one end being communicated with groove 3 from it, groove width reduces gradually, groove depth shoals gradually.Described drainage plate 4 is provided with the first projection 41 at the position of the connectivity part over against groove 3 and groove 3 left side drainage troughs 5, described drainage plate 4 is provided with the second projection 42 over against the position of the connectivity part of groove 3 and groove 3 right side drainage troughs 5, the upside of described drainage plate 4 has the 3rd projection 43, the downside of described drainage plate 4 has the 4th projection 44, described drainage plate 4 is in the first projection the 41 and the 3rd projection 43, the first projection the 41 and the 4th projection 44, the second projection the 42 and the 3rd projection 43, wall between the second projection the 42 and the 4th projection 44 is cancave cambered surface, described the 4th projection 44 is over against the connection position of the sheep intestines groove 6 of groove 3 and groove 3 belows.The downside wall of described groove 3 forms horn mouth being communicated with in the close direction in positions the downward-sloping connection position of groove 3 and sheep intestines groove 6 that makes gradually to groove 3 and sheep intestines groove 6.Four edges and corners round-corner transitions of described groove 3.
During installation, first two siliceous mullite brick side-by-side dockings are made to the front side of a siliceous mullite brick and relative the fixing of rear side of another piece siliceous mullite brick, now, the groove of two siliceous mullite bricks surrounds injection pot, drainage trough surrounds drainage channel, sheep intestines groove forms sheep intestines passage, charging aperture material feeding with pressure material injecting mechanism from drainage channel, binding material enters injection pot through drainage channel, then under the first projection of drainage plate and the shunting action of the second projection along cancave cambered surface to the 3rd projection with the 4th protruding place direction filling, while filling to the 4th protruding place direction, connection position formation horn mouth due to groove and sheep intestines groove, be partially filled and enter sheep intestines groove, pressure material injecting mechanism stops material feeding after the charging aperture place pressure that senses drainage channel reaches certain value, now, two siliceous mullite bricks have bondd.Because the groove width of sheep intestines groove reduces gradually, groove depth shoals gradually, two siliceous mullite bricks are in standing process, part rarer in binding material can be through the bottom of sheep intestines groove, the bond effect of binding material in injection pot is increased, and due to the special tectonic of sheep intestines groove, thicker material is difficult for flowing downward at sheep intestines groove.
