In the full ceramic inner barrel of described preheater, the lower end of ceramic lacing film is connected with the upper end of another ceramic lacing film.
In the full ceramic inner barrel of described preheater, top pottery lacing film and heat resisting steel connector are fixed by connecting bolt, and the connecting bolt outside is equipped with sheath.
In the full ceramic inner barrel of described preheater, the lower end of top pottery lacing film and the upper end of ceramic lacing film connect as one by ceramic connecting plate and ceramic bolt.
In the full ceramic inner barrel of described preheater, the two ends of ceramic lacing film have the connecting hole corresponding with ceramic connecting plate and bottom pottery connecting plate.
In the full ceramic inner barrel of described preheater, pottery connecting plate in bottom is plate always.
In the full ceramic inner barrel of described preheater, the section form of top pottery lacing film and ceramic lacing film is dovetail grooved or Z-shaped.
The beneficial effects of the utility model are:
1, the full ceramic inner barrel of preheater is high temperature resistant, corrosion-resistant, wear-resistant, and long service life can improve the running rate of equipment place system, reduces hear rate, improves system throughput.
2, ceramic lacing film quality is light, labour intensity when effectively having reduced the workman and installing.
3, the section form of ceramic lacing film is dovetail grooved or Z-shaped, and the seam between two ceramic lacing films is the curve seam, and this type of attachment can effectively reduce inleakage than straight tube.
4, pottery connecting plate in bottom is straight plate, and this structure can be applied to the preheater of different-diameter, caused because of the difference of radian when having avoided connecting plate to be used for the preheater inner barrel of different-diameter and ceramic lacing film between friction, improved interchangeability.

The specific embodiment
Structure of the present utility model such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the full ceramic inner barrel of preheater is comprised of heat resisting steel connector 1, top pottery lacing film 2, ceramic bolt 3, ceramic connecting plate 4, ceramic lacing film 5, bottom pottery connecting plate 6, sheath 7 and connecting bolt 8.
See also Fig. 6, all have the hole that is fit to connecting bolt on heat resisting steel connector 1 and the top pottery lacing film 2, upper end and the heat resisting steel connector 1 of top pottery lacing film 2 is fixing by connecting bolt 8, the connecting bolt 8 outer sheaths 7 that are equipped with.Wherein, leave certain interval between top pottery lacing film 2 and the heat resisting steel connector 1, when the impact that is subject to a certain degree, play cushioning effect.Heat resisting steel connector 1 is used for hanging over preheater.
When making, heat resisting steel connector 1 can be made two rounds, and two top pottery lacing films 2 are fixing side by side by heat resisting steel connector 1.Below be to be fixed on side by side on the heat resisting steel connector 1 as example take two tops pottery lacing films 2 to describe.
See also Fig. 4 and Fig. 5, the lower end of top pottery lacing film 2 and the upper end of ceramic lacing film 5 connect as one by ceramic connecting plate 4 and ceramic bolt 3, pottery connecting plate 4 is to use in pairs, namely respectively is provided with a ceramic connecting plate 4 in the both sides of ceramic lacing film 5, connects as one by ceramic bolt 3.The up and down two ends of pottery lacing film 5 all have connecting hole, can determine that according to the size of preheater the quantity of ceramic lacing film 5 forms a complete ceramic lacing film, Fig. 4 and shown in Figure 5 be to be formed by two ceramic lacing films 5 serial connections, in fact be not limited to this quantity.
