Description
Technical field
The utility model relates to preheater technical field, specifically, relates to a kind of cement kiln ceramic inner barrel.
Background technology
At present; cement preheater is a kind of equipment utilizing the high-temperature tail gas of rotary kiln to heat cement raw material; the structure that existing cement kiln ceramic inner barrel adopts ceramic lacing film to be formed by connecting mostly; but the joint gap poor sealing of existing ceramic lacing film, causing damage to cylindrical shell, reduces service life; and the high-temperature tail gas of rotary kiln contains a large amount of dust; and flow velocity is fast, existing ceramic lacing film is inadequate to the resistance to erosion power of high-temperature tail gas, often can cause the damage of ceramic lacing film.
Summary of the invention
For the deficiencies in the prior art, it is strong that the purpose of this utility model is to provide a kind of compactness, is conducive to protection cylindrical shell and do not corroded, extend the cement kiln ceramic inner barrel in the service life of cylindrical shell.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of cement kiln ceramic inner barrel, comprise cylindrical shell, the inwall of described cylindrical shell is provided with cushion, the inwall of described cushion is provided with the ceramic lacing film of arc, the left side wall of described ceramic lacing film and right side wall have outward extending first projection and are formed centrosymmetric Z-shaped, the top of described ceramic lacing film is provided with and upwards extends two second projections, the first opening up groove is formed between described two second projections, the bottom of described ceramic lacing film is provided with downward opening the second groove mating accommodation two second projection, described ceramic lacing film is also provided with the through hole of more than 2 that run through upper and lower two ends, the positive sidewall of described ceramic lacing film is provided with wavy wind guide tank, the front of described ceramic lacing film is provided with the installing hole running through through hole.
Further illustrate, described cushion is high temperature resistant and resistant material is made.
Further illustrate, described cushion is provided with the groove vertically run through.
Compared with prior art, the utility model has following beneficial effect: the left side wall of ceramic lacing film and right side wall have outward extending first projection and formed centrosymmetric Z-shaped, two lacing films making left and right adjacent are engaged mutually, the top of described ceramic lacing film is provided with and upwards extends two second projections, the first opening up groove is formed between described two second projections, this design is adopted to save material, reduce costs, the bottom of described ceramic lacing film is provided with downward opening the second groove mating accommodation two second projection, during installation, be socketed with mating of the second groove by the second projection, neighbouring two lacing films are engaged mutually, adjacent two lacing film gaps are little and even, in use, due to the filling of expanded by heating and cement material, sealing property is further improved, described ceramic lacing film is also provided with the through hole of more than 2 that run through upper and lower two ends, makes ceramic lacing film hollow, saves ceramic material.This preheater inner barrel, compactness is strong, is conducive to protection cylindrical shell and is not corroded, extend the service life of cylindrical shell, adopt the structure of wavy wind guide tank, high-temperature tail gas is reduced the scouring force of ceramic lacing film, extends the service life of ceramic lacing film.
