Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but does not limit protection domain of the present utility model and range of application:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of inner core for cement preheater, comprises cylindrical shell 1, and the inwall of described cylindrical shell 1 is provided with cushion 2, and described cushion 2 is made for high temperature resistant and resistant material, such as stainless steel, copper.Described cushion 2 is provided with the groove 8 vertically run through, and the effect of groove 8 arrives cylindrical shell 1 to cushion heat, reduces the etching extent of cylindrical shell 1, increases the service life.The inwall of described cushion 2 is provided with the ceramic lacing film 3 of arc, described ceramic lacing film 3 is made up of the first wedge shape link plate 31 and the second wedge shape link plate 32, described first wedge shape link plate 31 is up big and down small wedge shape, second wedge shape link plate 32 is up-small and down-big wedge shape, first wedge shape link plate 31 is consistent with the wedge degree of two wedge shape link plates 32, described first wedge shape link plate 31 upper end has the first projection 4 extended to bottom, corresponding described first projection 4 of described second wedge shape link plate 32 offers coupling first groove 5, first wedge shape link plate 31 and the second wedge shape hang 32 plates when combining, described first projection 4 and the first groove 5 cooperatively interact.The top of described ceramic lacing film 3 is provided with and upwards extends two second projections 9, the second opening up groove 10 is formed between described two second projections 9, the bottom of described ceramic lacing film 3 is provided with downward opening the 3rd groove 12 mating accommodation two second projection 9, described ceramic lacing film 3 is also provided with the through hole 11 of more than 2 that run through upper and lower two ends, the positive sidewall of described ceramic lacing film 3 is provided with wavy wind guide tank 6, and the corner, front of described ceramic lacing film 3 is provided with the installing hole 7 running through ceramic lacing film 3.
