Description
Technical field
The utility model relates to a kind of preformed bricks, especially relates to a kind of preformed bricks for rotary kiln, belongs to pellet production equipment manufacturing technology field.
Background technology
In the pellet production technology of drying grate-rotary kiln-circular cooler, because of sintering temperature in rotary kiln high, the preformed bricks of taking root on kiln wall is in for a long time and surpasses under 1200 ℃ of states, at long-term high-temperature baking, strong hot air infiltration, pellet washes away, harden and expect in the situation of drawing crack, the anchor nails of the inside kiln lining being comprised of some resistant to elevated temperatures preformed bricks and refractory casting part is easy to fracture, cause preformed bricks often to occur getting loose, displacement, and then there is crack, the images such as breach, thereby strong hot air is infiltrated on the outer wall of rotary kiln by the crack of described preformed bricks bottom, cause rotary kiln outside wall temperature for a long time higher than 220 ℃.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of in the course of work of rotary kiln, the preformed bricks that forms inner kiln lining is not easy to occur the preformed bricks for rotary kiln loosening, displacement situation.
For solving the problems of the technologies described above adopted technical scheme, be: a kind of preformed bricks for rotary kiln, comprise interior radian and outer radian respectively with the interior radian of described inner liner of rotary kiln wall and the suitable preformed bricks body of outer radian, on described preformed bricks body two end walls radially, be provided with respectively at least one anti-fracture dowel, described preformed bricks body is connected with the refractory casting part of the adjacent described inner liner of rotary kiln wall of formation respectively by described anti-fracture dowel.
Further, the anti-fracture dowel arranging on the end wall described in each is two, and the anti-fracture dowel described in these two is arranged near on the preformed bricks body of outer radian one side along the thickness direction of described preformed bricks body.
Further, the anti-fracture dowel of each part being positioned on different end walls lays respectively at different horizontal planes.
Further, on the end wall described in each, be provided with the anti-hot blast infiltration groove of through-thickness.
Further, the longitudinal center line that is positioned at the anti-hot blast infiltration of each on different end walls groove lays respectively on the different faces of cylinder on described inner liner of rotary kiln wall.
Further, on the circumferential lateral wall of described preformed bricks body, be provided with heat-insulation layer.
Further, described heat-insulation layer is the light-weight insulating brick being embedded on the circumferential lateral wall of described preformed bricks body.
The beneficial effects of the utility model are: owing to being provided with respectively at least one anti-fracture dowel on described preformed bricks body two end walls radially, and described preformed bricks body is connected with the refractory casting part of the adjacent described inner liner of rotary kiln wall of formation respectively by described anti-fracture dowel.Like this, between described preformed bricks body and described refractory casting part except the large anchor nails of original welding V-type is fixing, can also further reinforce grappling by described anti-fracture dowel, thereby described preformed bricks body had both been made after the large anchor nails fracture of welding V-type, still there is described anti-fracture dowel to be connected with described refractory casting part, and then making described rotary kiln in the course of the work, the preformed bricks that forms described inner liner of rotary kiln wall is not easy to occur situation loosening, displacement.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of preformed bricks for rotary kiln of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the schematic diagram of the inner liner of rotary kiln wall that relates to of the application;
Fig. 4 is the partial view of the inner liner of rotary kiln wall that relates to of the application.
In figure, be labeled as: inner liner of rotary kiln wall 1, preformed bricks body 2, end wall 3, anti-fracture dowel 4, refractory casting part 5, anti-hot blast infiltration groove 6, circumferential lateral wall 7, heat-insulation layer 8, the large anchor nails 9 of welding V-type.
The specific embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4 be the utility model provide a kind of in the course of work of rotary kiln, the preformed bricks that forms inner kiln lining is not easy to occur the preformed bricks for rotary kiln loosening, displacement situation.Described preformed bricks comprise interior radian and outer radian respectively with the interior radian of described inner liner of rotary kiln wall 1 and the suitable preformed bricks body 2 of outer radian, it is characterized in that: on described preformed bricks body 2 two end walls 3 radially, be provided with respectively at least one anti-fracture dowel 4, described preformed bricks body 2 is connected with the refractory casting part 5 of the adjacent described inner liner of rotary kiln wall 1 of formation respectively by described anti-fracture dowel 4.Owing to being provided with respectively at least one anti-fracture dowel 4 on described preformed bricks body 2 two end walls 3 radially, and described preformed bricks body 2 is connected with the refractory casting part 5 of the adjacent described inner liner of rotary kiln wall 1 of formation respectively by described anti-fracture dowel 4.Like this, between described preformed bricks body 2 and described refractory casting part 5 except the large anchor nails 9 of original welding V-type is fixing, can also further reinforce grappling by described anti-fracture dowel 4, thereby described preformed bricks body 2 had both been made after large anchor nails 9 fractures of welding V-type, still there is described anti-fracture dowel 4 to be connected with described refractory casting part 5, and then making described rotary kiln in the course of the work, the preformed bricks body 2 that forms described inner liner of rotary kiln wall 1 is not easy to occur situation loosening, displacement.
Above-mentioned embodiment, in order further to increase the fracture energy that does of described preformed bricks body 2, the anti-fracture dowel 4 arranging on end wall 3 described in each is two, anti-fracture dowel 4 described in these two is arranged near on the preformed bricks body 2 of outer radian one side along the thickness direction of described preformed bricks body 2, and the anti-fracture dowel 4 of each part being positioned on different end walls 3 lays respectively at different horizontal planes.Simultaneously, for fear of rotary kiln strong hot air in the course of the work, be penetrated into the outer wall of rotary kiln, this outer wall temperature is risen so high, on end wall 3 described in each, be provided with the anti-hot blast infiltration groove 6 of through-thickness, and the longitudinal center line of each the described anti-hot blast infiltration groove 6 on different end walls 3 is laid respectively on the different faces of cylinder on described inner liner of rotary kiln wall 1.Like this, when described preformed bricks body 2 is built by laying bricks or stones on described inner liner of rotary kiln wall 1, described refractory casting part 5 just can be filled full described anti-hot blast infiltration groove 6 in casting process, like this, even there is crackle at preformed bricks body 2 with the seam crossing that refractory casting part 5 is connected, also can by a described part that is filled in the refractory casting part 5 in described anti-hot blast infiltration groove 6, effectively hinder the infiltration of load strong hot air, reach the object of avoiding outer wall temperature to rise so high.Further, in order to reduce the heat penetration of described inner liner of rotary kiln wall 1, on the circumferential lateral wall 7 of described preformed bricks body 2, be provided with heat-insulation layer 8, and described heat-insulation layer 8 is set to be embedded in the light-weight insulating brick on the circumferential lateral wall 7 of described preformed bricks body 2.
