Abstract

The utility model discloses high-alumina bricks used for a lime sleeve kiln. Each high-alumina brick comprises a brick body. The front surface of the brick body is provided with a groove and the rear surface of the brick body is provided with a convex rib. The upper surface of the brick body is an arc surface. The left side surface and the right side surface of the brick body are both rectangular in geometry. The groove is positioned in the middle of the front surface of the brick body, and the convex rib is positioned in the middle of the rear surface of the brick body. Corners of the brick body are designed to be arc surfaces, such that brick bodies tend not to be bumped to lose corners or to crack when stones are thrown into a kiln during a sintering process. Meanwhile, friction among brick bodies is reduced, the loss of each brick body itself is minimized, and each brick body can be easily assembled with other matching brick bodies. Furthermore, each brick body, compact in structure, has a convex rib and a groove, so bricks can better match each other to form a whole body. Flames tend not to jump outwardly, safety hidden troubles can be eliminated and energy can be saved.

Description

A kind of lime sleeve kiln high-alumina brick

Technical field

The utility model relates to the brick body that a kind of fire resisting material field is used, and is specifically related to a kind of lime sleeve kiln high-alumina brick.

Background technology

At present, the shape of the high-alumina brick that lime sleeve kiln is used is cuboid or square nothing more than, adopt the lime sleeve kiln of this brick body in use, when adding stone, fragment of brick is easily by clashing and breaking, and between fragment of brick and fragment of brick, has certain gap, easily in sintering procedure, there is the fiery phenomenon that leaps up, not only cause waste of material, and have very large potential safety hazard, do not meet modern production demand.

Utility model content

Goal of the invention: for solving the deficiencies in the prior art, the utility model provides a kind of lime sleeve kiln high-alumina brick.

Technical scheme: for achieving the above object, a kind of lime sleeve kiln high-alumina brick of the present utility model, comprises brick body, and the front surface of brick body is provided with groove, and the rear surface of brick body is provided with fin; The upper surface of described brick body is arc surface, and the geometry of left and right two sides of described brick body is rectangle; Described groove is positioned at the centre position of brick body front surface; Described fin is positioned at the centre position of brick body rear surface.

As preferably, the cross section of described fin is semicircle, and the cross section of described groove be semicircle, and groove is fitted mutually with the size of fin.Join

In actual use, the fin of a brick body rear surface agrees with mutually with the groove of another piece brick body front surface; Two drift angle places of described brick body bottom surface adopt cambered surface design, adopt this design can make more easily the utility model and its matched brick assemble.

Beneficial effect: a kind of lime sleeve kiln high-alumina brick of the present utility model, by adopting cambered surface to design at several drift angles place, while making in sintering procedure to throw in stone in kiln, brick body is difficult for being damaged and causes unfilled corner or fracture; Meanwhile, can also reduce the frictional force between fragment of brick, reduce the loss of self, and between brick body and its matched brick, also be easier to assembling; In addition, fin of the present utility model and groove design, can make more to agree with between brick and brick, forms integral body, compact conformation, and flame is difficult for outwards leaping up out, not only can eliminate safe hidden trouble but also can save the energy.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the polycrystalline substance schematic diagram of Fig. 1;

Fig. 3 is the left view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described

As shown in Figure 1 to Figure 3, a kind of lime sleeve high-alumina brick of the present utility model, comprises brick body 1, the front surface of brick body 1 is provided with groove 2, the rear surface of brick body 1 is provided with fin 3, and the upper surface of brick body 1 is arc surface, and the geometry of left and right two sides of brick body 1 is rectangle; Described groove 2 is positioned at the centre position of brick body 1 front surface; Described fin 3 is positioned at the centre position of brick body 1 rear surface.

In the present embodiment, the cross section of fin 3 is semicircle, and the cross section of groove 2 is also semicircle, and groove 2 is suitable with the size of fin 3, and the position of the position of fin 3 and groove 2 is symmetrical.In actual use, the fin 3 of brick body 1 rear surface agrees with mutually with the groove 2 of another piece brick body 1 front surface; Two drift angle places of brick body 1 bottom surface adopt cambered surface design, adopt this design can make more easily the utility model and its matched brick assemble.

Below be only preferred embodiment of the present utility model; be noted that for those skilled in the art; not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
