Abstract

The utility model relates to a folding wedge-type firebrick. The geometric profile of the firebrick is that one end of the trapezoidal surface of the wedge-type firebrick is horizontally moved towards one side for a definite dimension so as to enhance the associative property among bricks in use. The utility model solves the phenomena of easy occurrence of a cement industry rotary kiln, such as firebrick sortition, tooth extraction, shoulder lifting, swing, etc.

Description

Folding formula wedge shape refractory brick

Technical field the utility model relates to a kind of improvement of refractory brick profile, and this refractory brick is mainly used in the cement industry rotary kiln.

The background technology cement rotary kiln is little because of existing wedge shape refractory brick concentric reducer stand out, the associativity difference is prone to lot, exodontia, shoulder, falls phenomenon such as brick between brick and the brick, cause hot spot, parking, influence the ordinary production of cement kiln and the life cycle of refractory brick.

Summary of the invention be overcome that existing wedge shape refractory brick concentric reducer stand out is little, the deficiency of associativity difference between brick and the brick, the utility model provides a kind of novel refractory brick, the associativity of this refractory brick is strong, not only can effectively avoid lot, exodontia, shoulder that existing refractory brick in use is prone to, fall phenomenon such as brick, and be convenient to inlaying of refractory brick.

The technical scheme that its technical problem that solves the utility model adopts is: the end of trapezoidal faces that will have wedge shape refractory brick now is to a side translation certain size, to strengthen the associativity between brick and the brick.Compare with existing wedge shape refractory brick, its advantage is: the folding formula wedge shape refractory brick in use associativity between brick and the brick is strong, when inlaying, and refractory brick can effectively be avoided lot, exodontia, shoulder during one's term of military service, fall phenomenons such as brick, and then the quality of inlaying of raising refractory brick, prolong the service life of refractory brick, reduce because of falling hot spot, the parking accident that brick causes.This advantage is particularly evident on the bigger rotary kiln of diameter.

Description of drawings further specifies the utility model below in conjunction with drawings and Examples.

Fig. 1 is the folding formula wedge shape refractory brick characteristic face schematic diagram that the utility model proposes.

Fig. 2 is the folding formula wedge shape refractory brick that the utility model proposes schematic diagram when using in rotary kiln.

1. folding formula wedge shape refractory brick characteristic face translation point, 2. folding formula wedge shape refractory brick, 3. cylinder of rotary kiln among the figure.

Specific embodiment Fig. 1 is embodiment of the present utility model.Be 1/3rd places of trapezoidal height apart from trapezoidal base, trapezoidal bottom is to a side translation, and for guaranteeing the rupture strength of refractory brick, the translation size should be 1/10th of translation place width.As shown in Figure 2, when folding formula wedge shape refractory brick was inlay in rotary kiln, the translation extension of a brick and the translation recessed portion of adjacent refractory brick coincided, and have stronger associativity.

Claims (1)

1. A kind of folding formula wedge shape refractory brick, the geometric shape that it is characterized in that this refractory brick are that the end of trapezoidal faces of wedge shape refractory brick is to a side translation.
