Abstract
The utility model relates to a full-ceramic preheater internal barrel, used in cement rotary kiln front preheater. The barrel is assembled by wear-resistant ceramic components, wherein, the wear-resistant ceramic components include assembled wear-resistant ceramic poles and arced ceramic connecting plates, corresponding joint holes are provided on the wear-resistant ceramic poles and arced ceramic connecting plates, and the wear-resistant ceramic poles and arced ceramic connecting plates are connected by ceramic connecting bolts and ceramic nuts through the joint holes. The utility model has advantages of low price, good high temperature antisepticise and wear resistance performance, long life cycle; the utility model not only has low cost, but also can ensure the continuity and stability of production.
Description
Technical field
The utility model relates to a kind of full internal barrel of ceramic pre-heater, is used in the preceding preheater of cement rotary kiln.
Background technology
At present, preheater inner barrel adopts heat resisting steel to make more before the cement rotary kiln, because high-temperature refractory steel costs an arm and a leg, high-temperature anticorrosion, anti-wear performance are not good again, cause the inner core life cycle shorter, not only increase cost, and the continuity that influence in neat formation is produced is with stable.
The utility model content
The purpose of this utility model is to provide a kind of full internal barrel of ceramic pre-heater, and price is low, and high-temperature anticorrosion, anti-wear performance are good, and life cycle is long, and not only cost is low, and can guarantee the continuity and stability of producing.
Full internal barrel of ceramic pre-heater described in the utility model, cylindrical shell is arranged, its cylindrical shell is assembled by the wear-resistant ceramic assembly, the wear-resistant ceramic assembly comprises the wear-resistant ceramic post and the arced ceramic connecting plate of splicing assembling, wear-resistant ceramic post and arced ceramic connecting plate are provided with corresponding connecting hole, and the wear-resistant ceramic post is connected with ceramic nut by ceramic connecting bolt by connecting hole with the arced ceramic connecting plate.
The wear-resistant ceramic post can be solid construction, also can be hollow-core construction, preferred hollow-core construction, hollow-core construction, not only easy to make, and can in hollow lumen, fill fire-resistant abrasion-proof and water material feeding, its high-temperature wearable time both prolonged, can reduce its cost of manufacture again, because castable refractory is low than wear-resistant ceramic cylinder price.
Establishing corresponding primary and secondary docking port in wear-resistant ceramic post splicing side, can be corresponding lap buckle limit, also can be corresponding projection and groove, or the like, make things convenient for the splicing between the wear-resistant ceramic post to connect.
The attached successively fire-resistant abrasion-proof of outer surface of the cylindrical shell that constitutes at the wear-resistant ceramic post waters material feeding and coating, can make fire-resistant abrasion-proof water material feeding, coating constitutes an integral body with the wear-resistant ceramic post, improves performance, and raising intensity increases the service life.
The pottery connecting plate constitutes circle by multistage, can be located at the two ends up and down of wear-resistant ceramic post, or distribution design upper, middle and lower three rows, can certainly be four rows etc., strengthens bonding strength.The pottery connecting plate can be in the inboard of cylindrical shell or the outside or inside and outside both sides all use.
The cross section of wear-resistant ceramic post can be square, rectangle, huge font, shape such as trapezoidal, fan-shaped.
The utility model adopts the mode of splicing assembling, can use wear-resistant ceramic material, and price is low, wear resistance at elevated temperature is good, and life cycle is long, and operating cost is low, and the continuity that can guarantee to produce has guaranteed the ordinary production of cement rotary kiln, remarkable benefit with stable.
Description of drawings

A-A cross section structure schematic diagram among Fig. 2, Fig. 1.
Among the figure: 1, ceramic connecting plate 2, ceramic bolt 3, wear-resistant ceramic post 4, ceramic nut 5, ceramic connecting plate.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
As shown in the figure, full internal barrel of ceramic pre-heater described in the utility model, its cylindrical shell is assembled by the wear-resistant ceramic assembly, the wear-resistant ceramic assembly comprises the wear-resistant ceramic post 3 of splicing assembling and the ceramic connecting plate 1,5 of arc, can there be corresponding primary and secondary docking port the splicing side of wear-resistant ceramic post 3, convenient splicing butt joint, wear-resistant ceramic post 3 and ceramic connecting plate 1,5 are provided with corresponding connecting hole, and wear-resistant ceramic post 3 is connected with ceramic nut 4 by ceramic connecting bolt 2 by connecting hole with ceramic connecting plate 1,5.
Wherein, wear-resistant ceramic post 3 is preferably hollow-core construction, be filled with fire-resistant abrasion-proof in the hollow lumen and water material feeding, the outer surface of the cylindrical shell that wear-resistant ceramic post 3 constitutes waters material feeding and coating with fire-resistant abrasion-proof successively, and fire-resistant abrasion-proof waters material feeding, coating and wear-resistant ceramic post 3 and constitutes an integral body.
