Description
Technical field
The present invention relates to a kind of for the ceramic inner barrel of preheater in cement producing line preheater.
Background technology
At present, domestic inner cylinders of cement kiln preheaters many employings heat-resisting alloy lacing film is formed, in cement production process, lacing film is subject to high temperature, and the corrosion of alkali steam, sulphur steam and powder is washed away, and causes heat resisting steel lacing film to be out of shape, peel off, be only about 1 year service life, stop kiln and change carrying out continuously of not only impact production, too increase manufacture of cement cost.The preheater inner barrel of some manufacturer production adopts ceramic lacing film, be improved than heat resisting steel in material property, due to material composition, the existing defects such as project organization, concentrate as bolt junction easily produces stress, thermal shock resistance is poor, in use easily cracks, and even ablation is ruptured, and delays production.
Summary of the invention
The object of the present invention is to provide a kind of high temperature resistant, corrosion-resistant, not easy fracture, the ceramic inner barrel of preheater that service time is long.
For achieving the above object, ceramic inner barrel of preheater provided by the invention, is hung on the inwall of preheater by several mutually isostructural ceramic inner barrel hanging sheets, thus forms ceramic inner barrel with arranging; Wherein, the structure of ceramic inner barrel hanging sheet is:
Pottery hanging tube is fixed on heat resisting steel suspension member, and the upper end of heat resisting steel suspension member is a hook, hanging support and be fixed on the inwall of preheater;
Middle part and the bottom of pottery hanging tube have connecting hole, and adjacent ceramic hanging tube is linked into an integrated entity by fishplate bar.
Described ceramic inner barrel of preheater, wherein, ceramic hanging tube is fixed on heat resisting steel suspension member by connecting bolt.
Described ceramic inner barrel of preheater, wherein, connecting bolt outside is provided with ceramic sheath.
Described ceramic inner barrel of preheater, wherein, heat resisting steel suspension member lower end is a bead, and the position that ceramic hanging tube is corresponding is provided with a step, and when ceramic hanging tube is fixed on heat resisting steel suspension member, the bead of heat resisting steel suspension member lower end matches with the step of ceramic hanging tube.
Described ceramic inner barrel of preheater, the quadrangle that wherein, the cross sectional shape of ceramic hanging tube is two straight flanges be parallel to each other, a concave arc and a dome arc surround.
Described ceramic inner barrel of preheater, wherein, the structure of connecting hole is top is circular, and middle part is rectangle, and bottom is semicircle.
Described ceramic inner barrel of preheater, wherein, the step on ceramic hanging tube is arc-shaped.
The invention has the beneficial effects as follows:
1, ceramic lacing film adopts single piece type overall structure, avoids mode with bolts, effectively can improve thermal shock performance, Crack prevention and the ablation breakage problem of pottery.
2, fastening means adopts pin to connect, and reduces the use of bolt, effectively cost-saving.
3, top connected mode can shock absorbing, reducing because shaking the injury caused, improving service life.
4, the structure of lacing film is conducive to combining closely between two lacing films, prevents from leaking out, and increases the stability of lacing film in environment for use.

Detailed description of the invention
Ceramic inner barrel of preheater provided by the invention, comprising: heat resisting steel suspension member, ceramic hanging tube, connecting bolt, ceramic sheath, ceramic pins, backplate.
Wherein, ceramic hanging tube is connected on heat resisting steel suspension member by connecting bolt, is fixed the position of whole lacing film by heat resisting steel suspension member.Connecting bolt outside is provided with ceramic sheath.
Pottery hanging tube is the top structure slightly wider than bottom, and outstanding step is arc-shaped.
In the middle part of pottery hanging tube and bottom has connecting hole, and be provided with ceramic pins in connecting hole, adjacent ceramic hanging tube is linked into an integrated entity by ceramic pins and connecting plate.
The irregular quadrilateral that the cross sectional shape of pottery hanging tube is two straight flanges, a concave arc and a dome arc surround.
Structure Figure is further described structure of the present invention below.It should be noted that, the upper and lower, left and right etc. mentioned in below illustrating all refer to direction shown in the drawings
Fig. 1 be ceramic inner barrel hanging sheet of the present invention arrangement hang over preheater inwall on form the schematic perspective view after ceramic inner barrel.
Ceramic inner barrel hanging sheet structure of the present invention as shown in Figure 2, is be fixed on heat resisting steel assembly 1 by ceramic hanging tube 2, several mutually isostructural ceramic inner barrel hanging sheet arrangements is hung on the inwall of preheater, thus forms ceramic inner barrel.
Refer to Fig. 3, its body of heat resisting steel assembly 1 of fixing ceramic hanging tube 2 is one is Z-shaped heat resisting steel suspension member 4, heat resisting steel suspension member 4 upper end is a hook 41, for hanging support and the inwall being fixed on preheater, the lower end of heat resisting steel suspension member 4 is a bead 42, for matching with the step 21 of ceramic hanging tube 2, increase heat resisting steel suspension member 4 and fastness between ceramic hanging tube 2.The side of heat resisting steel suspension member 4 is provided with the connecting bolt 5 of fixing ceramic hanging tube 2, and ceramic sheath 6 is housed outside connecting bolt 5, to prevent under the environment of high temperature containing etchant gas the erosion of connecting bolt and washes away.
Fig. 4 is the structural representation of ceramic hanging tube 2, the top of ceramic hanging tube 2 of the present invention is than the slightly wide formation one in bottom step 21, when actual assembled, the step 21 of pottery hanging tube 2 matches with the bead 42 of heat resisting steel suspension member 4 lower end, step 21 is arc-shaped, for effectively reducing impact during collision, simultaneously easily manufactured.Middle part and the bottom of pottery hanging tube 2 all have connecting hole 3, and its shape as shown in Figure 5.The structure of connecting hole is top is circular a, and middle part is rectangle b, and bottom is semicircle c.During application, connecting plate (well-known components, not shown in the figures) and ceramic hanging tube 2 are by being connected and fixed through the ceramic pins of connecting hole 3.The quantity of connecting hole 3 can carry out increasing and decreasing to reach best result of use according to the length of ceramic hanging tube 2.
