Abstract
The invention discloses a preheater inner barrel for a cement production kiln. The preheater inner barrel comprises a barrel body, wherein a buffer layer is mounted on the inner wall of the barrel body; arc-shaped ceramic hanging pieces are mounted on the inner wall of the buffer layer; a first bump stretching outwards is arranged on each of the left side wall and the right side wall of each ceramic hanging piece to form a centrosymmetric Z shape; a second bump stretching upwards is arranged at the top end of each ceramic hanging piece; a groove which can fit and accommodate the second bump and has a downward opening is formed in the bottom end of each ceramic hanging piece; two or more through holes penetrating through the upper and lower ends are formed in each ceramic hanging piece; wavy wind guide grooves are formed in the front side wall of each ceramic hanging piece; and mounting holes penetrating through the through holes are formed in the front side of each ceramic hanging piece. According to the preheater inner barrel, the structure that the ceramic hanging pieces are connected in a manner that each groove is connected with the corresponding bump in a sleeving manner is adopted, so that the ceramic hanging pieces are in seamless connection, the compactness is high, the barrel body is prevented from being corroded, and the service life of the barrel body is prolonged.
Description
Technical field
The present invention relates to preheater technical field, specifically, relate to a kind of kiln preheater inner barrel producing cement.
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 the kiln preheater inner barrel of existing production cement 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, the object of this invention is to provide a kind of compactness strong, be conducive to protection cylindrical shell and do not corroded, the kiln preheater inner barrel producing cement service life extending cylindrical shell produces the kiln preheater inner barrel of cement.
For achieving the above object, the present invention is achieved by the following technical solutions: a kind of kiln preheater inner barrel producing cement, 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 the second projection, the bottom of described ceramic lacing film is provided with the downward opening groove mating accommodation 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 present invention 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 the second projection, the bottom of described ceramic lacing film is provided with the downward opening groove mating accommodation second projection, during installation, 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.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but does not limit the scope of the invention and range of application:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of kiln preheater inner barrel producing cement, comprises cylindrical shell 1, and the inwall of described cylindrical shell 1 is provided with cushion 2, and described cushion 2 is high temperature resistant and resistant material is made; As stainless steel, copper etc.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, the left side wall of described ceramic lacing film 3 and right side wall have outward extending first projection 9 and are formed centrosymmetric Z-shaped, the top of described ceramic lacing film 3 is provided with and upwards extends the second projection 4, the bottom of described ceramic lacing film 3 is provided with the downward opening groove 5 mating accommodation second projection 4, described ceramic lacing film 3 is also provided with the through hole 41 of more than 2 that run through upper and lower two ends, and the front of described ceramic lacing film 3 is provided with the installing hole 7 running through through hole 41.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.
This preheater inner barrel, the left side wall of pottery lacing film 3 and right side wall have outward extending first projection 4 and are formed centrosymmetric Z-shaped, two lacing films making left and right adjacent are engaged mutually, the top of described ceramic lacing film 3 is provided with and upwards extends the second projection 4, the bottom of described ceramic lacing film 3 is provided with the downward opening groove 5 mating accommodation second projection 4, during installation, 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 3 is also provided with the through hole 41 of more than 2 that run through upper and lower two ends, makes ceramic lacing film 3 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 6, high-temperature tail gas is reduced the scouring force of ceramic lacing film 3, extends the service life of ceramic lacing film 3.
