Abstract

The utility model discloses a reducing brick. The geometric shapes of the orthographic projections of the six faces of a brick body are trapezoid; moreover, the length of an upper edge of the trapezoid is more than that of a lower edge of the trapezoid. The reducing brick has strong compression resistant capacity and good thermal preservation effect; when one reducing brick is damaged, the damaged brick can be replaced, and the other reducing bricks can be used continuously; therefore, the cost is greatly reduced; besides, as the volume of the brick body is smaller, the reducing brick is convenient to clear up and maintain.

Description

A kind of reducing brick

Technical field

The utility model belongs to fire resisting material field, is specifically related to a kind of reducing brick.

Background technology

At present, cement rotary kiln is extensive use of.Sometimes, change the bore of rotary kiln, perhaps increase or reduce, to meet the different needs owing to need.Based on above-mentioned requirements, traditional mode is directly to be made into the size that needs with cement deposit material.But this way has a lot of drawbacks: the one, and the character of cement deposit material own is limit, and resistance to compression is little, and it is poor to be incubated; The 2nd, there is place, a place that breakage is arranged if water material feeding, so wholely water material feeding and just can not continue again to have used, make cost raise.

Summary of the invention

Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of reducing brick is provided.

Technical scheme: in order to solve the defective that exists in the present technology, the utility model specifically is achieved like this: a kind of reducing brick, the geometry of six face orthographic projections of brick body is trapezoidal, and upper base length is greater than going to the bottom.

Can be according to the size of kilneye bore, and the size of demand bore, the length of going to the bottom on the reducing brick is set, and the number that uses the reducing brick.

Beneficial effect: compared with prior art, the utlity model has following advantage: pressure resistance, high insulating effect occurs can only changing that damaged piece when damaged as the reducing brick, other can continue use, greatly reduce cost; In addition, because brick body volume is littler, is convenient to cleaning, safeguards.

Fig. 1 is the structural representation of reducing brick;

Fig. 2 is the user mode figure of reducing brick.

The specific embodiment

As shown in Figure 1, the reducing brick that the utility model provides, the geometry of six face orthographic projections of brick body is trapezoidal, and upper base length is greater than going to the bottom.

As shown in Figure 2, a kind of in the utility model user mode, being joined by 4 reducing bricks forms, and the reducing mouth of its composition is suitable for reading greater than end opening, plays the effect of concentrating or disperseing kiln flame.

Claims (1)

1. a reducing brick is characterized in that, the geometry of six face orthographic projections of described reducing brick is trapezoidal, and upper base length is greater than going to the bottom.
