Middle part and the bottom of pottery hanging tube have connecting hole, and adjacent ceramic hanging tube links into an integrated entity by fishplate bar.
Described ceramic inner barrel of preheater, wherein, ceramic hanging tube is fixed on the heat resisting steel suspension member by connecting bolt.
Described ceramic inner barrel of preheater, wherein, the connecting bolt outside is equipped 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 the 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, wherein, the cross sectional shape of ceramic hanging tube is two straight flanges that are parallel to each other, a concave arc and a quadrangle that the dome arc surrounds.
Described ceramic inner barrel of preheater, wherein, the structure of connecting hole is that 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 circular-arc.
The invention has the beneficial effects as follows:
1, ceramic lacing film adopts the single piece type overall structure, avoids mode with bolts, can effectively improve ceramic thermal shock performance, Crack prevention and ablation breakage problem.
2, fastening means adopts pin to connect, and reduces the use of bolt, effectively cost-saving.
3, the top connected mode can shock absorbing, reduces the injury caused because of vibrations, improves 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.
