Abstract
The utility model discloses a circular-truncated-cone type lining structure of a high-temperature zone of a calcinations rotary kiln. The circular-truncated-cone type lining structure comprises a kiln barrel body, a heat-preservation layer and refractory bricks, wherein the heat-preservation layer is arranged on the inner wall of the kiln barrel body, and the refractory bricks are arranged on the inner wall of the heat-preservation layer so as to constitute a refractory brick lining layer; the surface of at least one refractory brick in at least one ring of the refractory brick lining layer in the high-temperature zone of the rotary kiln is provided with a circular-truncated-cone type raising block so as to be higher than the surfaces of other positions of the refractory brick lining layer. By the adoption of the lining structure, materials can be raised while turning over and sliding along with the rotary kiln, and therefore the gathered materials can be scattered, quality is improved after calcinations, sintering quality is good, and raw materials are saved. Because the materials are raised, abrasion to the raising blocks can be reduced, and the service life of each raising block is prolonged. Meanwhile, the inclination angle of the rotary kiln can be reduced appropriately, combustion impact, caused by the materials, to the inner wall of the rotary kiln is reduced, and prolonging of the service life of the rotary kiln is facilitated.
Description
Technical field
The utility model relates to a kind of inner lining structure, specifically relate to the inner lining structure of the high temperate zone of a kind of calcination rotary kiln circular table configuration.
Background technology
The liner of general calcination rotary kiln is when building by laying bricks or stones, inner barrel surface is all smooth alignment, highly identical, when kiln body rotates in heating, utilize the inclination of kiln body and the rotation of external force, material is with rotary kiln rotation and stir forward gradually and advance, and because material is at Action of Gravity Field, material is all that the rotary kiln inwall of fitting rolls.In fact, the rotary kiln inwall of round and smooth type can not be kicked up material, and most of material is the rotation along with kiln body, to front slide, material cannot be realized and fully the mixing of surface and bottom surface in cylinder of rotary kiln inwall contact, not out, bed of material internal-external temperature difference is larger for intermediate material upset, causes the material inequality of being heated, thereby the material sintering in the middle of causing is insufficient, thereby the quality after impact calcining knot, and because material is difficult for the sintering waste material that dispersion forms bulk, waste raw material.
Utility model content
The technical problems to be solved in the utility model is the problem and shortage existing for existing calcination rotary kiln interior wall construction, and the inner lining structure of the high temperate zone of a kind of calcination rotary kiln circular table configuration is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the inner lining structure of the high temperate zone of a kind of calcination rotary kiln circular table configuration, comprise kiln cylinder body, heat-insulation layer, refractory brick, described heat-insulation layer is arranged on kiln cylinder body inwall, described refractory brick is arranged on the inwall of heat-insulation layer and forms fireproof brick inner lining layer, in described rotary kiln high temperature region, have at least at least one refractory brick surface in the fireproof brick inner lining layer of a ring to be provided with circular table configuration lifting piece, make it exceed other fireproof brick inner lining layers surfaces.
Rotary kiln high temperature region wherein one ring fireproof brick inner lining layer in be evenly provided with four lifting pieces.
Described lifting piece is comprised of refractory casting material.
The height of described lifting piece is 2～5cm.
Preferably, the height of described lifting piece is 3cm.
Adopt the inner lining structure of the high temperate zone of a kind of calcination rotary kiln of the present utility model circular table configuration, so that the material of high-temperature region is kicked up when can and slide with rotary kiln upset, agglomerated material is together broken up, so that repetition sintering processes, prevent that the larger waste material of reuniting from generating, improve the quality after calcining, sintering quality is good, saves material.Because material is kicked up, can reduce the wearing and tearing of lifting piece, increase the service life of lifting piece.Also can suitably reduce the angle of inclination of rotary kiln, thereby reduce material, the burning of rotary kiln inwall is impacted the service life that is conducive to improve rotary kiln simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is section structure schematic diagram of the present utility model.
Shown in figure: 1-kiln cylinder body, 2-heat-insulation layer, 3-refractory brick, 4-inner liner, 5-lifting piece.
The specific embodiment
As shown in Figure 1, the inner lining structure of the high temperate zone of a kind of calcination rotary kiln of the present utility model circular table configuration, comprise kiln cylinder body 1, heat-insulation layer 2, refractory brick 3, described heat-insulation layer 2 is arranged on kiln cylinder body 1 inwall, described refractory brick 3 is arranged on the inwall of heat-insulation layer 2 and forms fireproof brick inner lining layer 4, has at least at least one refractory brick 3 surfaces in the fireproof brick inner lining layer 4 of a ring to be provided with circular table configuration lifting piece 5 in described rotary kiln high temperature region, makes it exceed other fireproof brick inner lining layer 4 surfaces.
Rotary kiln high temperature region wherein one ring fireproof brick inner lining layer 4 in be evenly provided with four lifting pieces 5.
Described lifting piece 5 is comprised of refractory casting material.
The height of described lifting piece 5 is 2～5cm.
Preferably, the height of described lifting piece 5 is preferably set to 3cm.
Adopt the inner lining structure of the high temperate zone of a kind of calcination rotary kiln of the present utility model circular table configuration, so that the material of high-temperature region is kicked up when can and slide with rotary kiln upset, agglomerated material is together broken up, so that repetition sintering processes, prevent that the larger waste material of reuniting from generating, improve the quality after calcining, sintering quality is good, saves material.Because material is kicked up, can reduce the wearing and tearing of lifting piece 5, increase the service life of lifting piece 5.Also can suitably reduce the angle of inclination of rotary kiln, thereby reduce material, the burning of rotary kiln inwall is impacted the service life that is conducive to improve rotary kiln simultaneously.
