Abstract

The utility model discloses a novel 19-hole lattice brick. The novel 19-hole lattice brick comprises a brick body, wherein 19 through holes are uniformly distributed in the brick body; a horizontal channel communicated with the hole openings of the more than two through holes are formed in the surface of the brick body; and the horizontal channel extends to the edge of the brick body. According to the novel 37-hole lattice brick, the U-shaped horizontal channel is formed in the surface of the lattice brick, and adjacent hole channels are communicated with each other, so that if part of the hole channels are blocked when in use, air can run from other unblocked hole channels, thereby avoiding temperature deviation or air supply at a low air temperature, caused by blockage of the hole channels, prolonging the life of the lattice brick and achieving the purposes of energy conservation and high efficiency.

Description

A kind of novel 19 hole lattice bricks

Technical field

The utility model relates to a kind of novel 19 hole lattice bricks.

Background technology

At present, the heat exchanger of metallurgy industry blast funnace hot blast stove generally uses checker brick, for energy-conservation general employing small-aperture lattice brick, because hotblast stove is in service in long term operation, combustion gases are with materials such as a small amount of CO and sulfonium ions, long-time running has the reaction of the scorification of erosion to refractory brick, causes the inclined to one side sintering fire of part aperture obstruction formation or air-supply wind-warm syndrome on the low side, increases ironmaking cost.

The utility model content

The purpose of this utility model provides a kind of novel 19 hole lattice bricks that can prevent effectively that the duct from stopping up.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of novel 19 hole lattice bricks comprise the brick body, are evenly distributed with the nineteen through hole on the brick body, and the brick surface is provided with the horizontal channel that is communicated with two above through hole apertures, and described horizontal channel extends to brick body edge.

Described horizontal channel has three and cross section to take the shape of the letter U, and three horizontal channels are extended to brick body edge line by the hole at brick body center respectively, and the angle between adjacent two horizontal channels is 120 °.

Described brick surface is regular hexagon.

In the utility model, on the checker brick surface U-shaped horizontal channel is set, adjacent duct connects mutually, in use stop up such as the fruit part duct, gas can be from other not plug-hole road operation, so both avoided stopping up partially fire or the air-supply of low wind-warm syndrome that causes because of the duct, prolonged again the life-span of checker brick, reached the purpose of efficient energy-saving.

Embodiment

As shown in Figure 1 and Figure 2, a kind of novel 19 hole lattice bricks, comprise that the surface is orthohexagonal brick body 1,1 two surfaces of brick body are respectively equipped with groove 4 and the boss 5 for docking, be evenly distributed with nineteen through hole 2 on the brick body 1, brick body 1 surface is provided with 3, three horizontal channels, horizontal channel that three cross sections that are communicated with apertures take the shape of the letter U and is extended to brick body edge line by the hole at brick body center respectively, angle P between adjacent two horizontal channels is 120 °, and rounded corner is carried out at each angle of U-shaped horizontal channel 3.

During the utility model work, horizontal channel 3 connects the duct of adjacent through-holes 2 mutually, can effectively prevent from effectively preventing the duct obstruction, has both prolonged the life-span of checker brick, has reached again the purpose of efficient energy-saving.In the utility model, horizontal channel 3 can be arranged on a surface of brick body, also can all arrange on two surfaces.

Claims
