Abstract
The utility model discloses a structure for connecting adjacent hanging pieces of a ceramic inner cylinder used in a preheater of a cement kiln. The structure comprises horizontally and vertically adjacent single hanging pieces each comprising a front piece and a back piece, a reinforcement structure is arranged between the front piece and the back piece, and mounting holes are disposed on upper ends and lower ends of the front piece, the back piece and the reinforcement structure. Vertically adjacent single hanging pieces are connected through a group of ceramic connecting pieces, and horizontally adjacent single hanging pieces are connected through a group of cast steel locking pieces, thereby enabling the assembly process to be convenient and rapid, raising overall sealing performance and structural strength, ensuring structural integrity of the hanging pieces during the assembly and using processes, and prolonging service life.
Description
Technical field
The utility model relates to a kind of cement kiln preheaters adjacent lacing film syndeton of ceramic inner barrel.
Background technology
Original cement kiln preheater adopts heat resisting steel or two kinds of materials of carborundum with the inner core lacing film more, but in preheater under the washing away of high temperature dust wind sand, the inner core lacing film wearing and tearing of heat resisting steel material are very serious, simultaneously because preheater inside has been full of high-temperature alkaline gas, so that heat resisting steel very easily produces oxide etch, service life is short; And the inner core lacing film of silicon carbide material, although can wear resistant corrosion resistant, cost is high, and the production cycle is long, and cracky.Original deficiency for a change, domestic water stall ceramic inner cylinder for preheater at present adopts ceramic lacing film to be formed by connecting, but adjacent lacing film is difficult for assembling, and leave the gap, poor sealing performance more.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to assembly and ceramic inner barrel hanger for cement kiln preheater structure that sealing property is high.
The utility model is achieved through the following technical solutions: a kind of cement kiln preheaters adjacent lacing film syndeton of ceramic inner barrel, comprise the monomer lacing film that upper and lower, left and right are adjacent, one group of pottery brace connects upper and lower adjacent monomer lacing film, and one group of cast steel locking plate connects left and right adjacent monomer lacing film.
Described monomer lacing film comprises anter, rear panel, is provided with the reinforcement structure between described anter and rear panel, is provided with installing hole at the upper and lower end of described anter, rear panel and reinforcement structure.
Described reinforcement structure is for strengthening steel plate or being alveolate texture spare.
Described anter and rear panel are made by ceramic material.
Beneficial effect: a kind of cement kiln preheaters adjacent lacing film syndeton of ceramic inner barrel that the utility model proposes, upper and lower adjacent monomer lacing film connects by one group of pottery brace, left and right adjacent monomer lacing film connects by one group of cast steel locking plate, so that assembling process is convenient, fast, overall sealing performance and structural strength are high, guaranteed that lacing film keeps structural integrity in installation, use procedure, avoided damaging, thereby prolonged service life.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model monolithic hanging chip structure schematic diagram.
The specific embodiment
As shown in Figure 1, 2, this cement kiln preheaters comprises the monomer lacing film that upper and lower, left and right are adjacent with the adjacent lacing film syndeton of ceramic inner barrel, described monomer lacing film comprises anter 1, rear panel 2, between described anter 1 and rear panel 2, be provided with and strengthen structure 3, be provided with installing hole 4 in described anter 1, rear panel 2 and the upper and lower end of strengthening structure 3.Described reinforcement structure 3 describes as an example of the reinforcement steel plate example in the present embodiment for strengthening steel plate or being alveolate texture spare.
One group of pottery brace 5 connects upper and lower adjacent monomer lacing film by installing hole 4, and one group of cast steel locking plate 6 connects left and right adjacent monomer lacing film by installing hole 4.
Described anter 1 and rear panel 2 are made by ceramic material.Its heat resisting temperature is up to 1300 ℃, is higher than 1150 ℃ of the upper limit temperature of heat tolerance of heat resisting steel inner core lacing film, and it has good stability simultaneously, has higher hardness, and Mohs' hardness reaches 8-9, has good anti-wear performance; Simultaneously, its acid resistance is higher than 95%, and alkali resistance reaches a class, in pyroprocess with any alkali sulfurous gas that contains without any reaction, have good high temperature resistant, decay resistance, effectively prolonged service life.
The above only be the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
