Abstract

The utility model relates to a pushed slab kiln high-temperature area kiln body vault of a stable structure. The pushed slab kiln high-temperature area kiln body vault comprises middle vault bricks and inner vault bricks, two connection faces of each inner vault brick are inclined faces, and the two inclined faces of each inner vault brick are respectively provided with a step. The pushed slab kiln high-temperature area kiln body vault is characterized by further comprising vault corner bricks. Two connection faces of each middle vault brick are inclined faces, one connection face of each vault corner brick is an inclined face, one of inclined face of each middle vault brick and the inclined face of each vault corner brick are respectively provided with a step, the left and the right of each middle vault brick are respectively connected with one inner vault brick, and one side of each inner vault brick is connected with one vault corner brick. The pushed slab kiln high-temperature area kiln body vault has the advantages that connection of the vault bricks is tight, the vault bricks can not fall off easily, and device maintenance cost is reduced.

Description

A kind of constitutionally stable pushed bat kiln high-temperature region kiln body vault

Technical field

The utility model relates to a kind of pushed bat kiln high-temperature region kiln body vault, relates in particular to a kind of constitutionally stable pushed bat kiln high-temperature region kiln body vault.

Background technology

at present, nitrogen atmosphere protection pushed slab kiln is the agglomerating plant in the magnetic materials production process, common kiln body in high-temperature region of pushed slab kiln under protection of nitrogen atmosphere vault is to be connected and to be formed by six blocks of key bricks, it comprises key brick in two, two interior key bricks and two outer key bricks, have a semi-circular recesses on one joint face of middle key brick, another joint face is inclined plane, two joint faces of interior key brick are inclined plane, one joint face of outer key brick is inclined plane, at middle key brick, have on the inclined plane of interior key brick and outer key brick and respectively be provided with a step, middle key brick, interior key brick and outer key brick left-right symmetry are arranged and are installed, the semi-circular recesses of two blocks of middle key bricks forms a jack, is provided with a pin in jack.After pushed bat kiln high temperature firing end-of-job, the cooling contraction of key brick, because the vault fragment of brick number of this vault is more, after using a period of time, it is large that gap between key brick after contraction becomes, and the interaction force between key brick diminishes, and easily causes coming off of key brick, destroy the structure of kiln body, increased the cost of plant maintenance.

Summary of the invention

For above shortcoming, the purpose of this utility model is to provide between a kind of key brick and connects tight, difficult drop-off, reduces the constitutionally stable pushed bat kiln high-temperature region kiln body vault of cost of equipment maintenance.

Technology contents of the present utility model is: a kind of constitutionally stable pushed bat kiln high-temperature region kiln body vault, it comprises middle key brick and interior key brick, two joint faces of interior key brick are inclined plane, respectively be provided with a step on two inclined planes of interior key brick, it is characterized in that it also comprises the arch angle brick, two joint faces of middle key brick are inclined planes, one joint face of arch angle brick is inclined plane, respectively be provided with a step on the inclined plane of middle key brick and arch angle brick, middle key brick left and right respectively connects an interior key brick, at side connection one an arch angle brick of interior key brick.

Compared with prior art, advantage of the present utility model is: reduced the piece number of key brick, at vault, lowered the temperature, gap between key brick can be not excessive, guaranteed interaction force required between key brick, the key brick difficult drop-off, reduced the cost of plant maintenance.
