Abstract

It is a hot-blast furnace high efficient lattice brick and belongs to the lattice brick used for the checker chamber of the hot-blast furnace while the hot-blast furnace is an auxiliary equipment of the blast furnace. The lattice brick is in the shape of straight barrel. The checker chamber built with this lattice brick can eliminate the heat exchange blind area and then makes every m + [3]lattice brick provided with more heating area while the draft loss of the checker chamber can not be increased.

Description

Hot-blast furnace high efficient lattice brick

The efficient checker brick of a kind of hot-blast stove belong to the blast furnace ancillary service---the checker brick for building of chamber of hot-blast stove.

The checker brick of hot-blast stove use at present have two types:

One, the checker brick that have vertical channel.The chamber of hot-blast stove that this checker brick are built into has the vertical channel of identical pass, as veneer brick, five hole checker brick, seven apertures in the human head checker brick etc.The advantage of this checker brick is that air loss is little, and deashing is convenient.Shortcoming is to have the interchange of heat dead band, every m ³The heating surface that checker brick have is little.

Two, spherical checker brick.There is not the interchange of heat dead band in this checker brick, every m ³The heating surface maximum that checker brick have.Shortcoming is that air loss is big, and the deashing inconvenience should not be used on large blast furnace.

Purpose of design of the present utility model is to eliminate checker brick interchange of heat dead band, makes every m ³Checker brick have bigger heating surface, can make regenerator keep vertical hot-air channel again.Make this checker brick still have the little and deashing of air loss advantage easily.

Solution of the present utility model is that checker brick are made straight tubular, when building chamber of hot-blast stove by laying bricks or stones, around each checker brick, closely arranges six checker brick, and make between the checker brick all be some the contact, this has just eliminated the interchange of heat dead band, makes every m ³Checker brick have bigger heating surface.The hot-air channel that this checker brick are built into has two kinds of passes, i.e. the polygon vertical channel of garden shape (or polygon) vertical channel of endoporus composition and checker brick outer wall camber line composition.

The utility model is compared with original checker brick, has both had the big advantage of spherical checker brick heating surface, has kept vertical hot-air channel again, has the low and deashing of air loss advantage easily.

Accompanying drawing 1: the vertical view and the longitudinal plan of efficient checker brick.

Accompanying drawing 2: efficient checker brick are built schematic diagram by laying bricks or stones.

Embodiment accompanying drawings of the present utility model is as follows:

The structure of this efficient checker brick (as shown in Figure 1) is straight tubular.Its inner hole wall and outer wall are circular (or polygon).An inside recessed groove (1) is arranged at the bottom of endoporus; A convex edge (2) of outwards protruding is arranged at the top of endoporus, and this convex edge (2) are slightly less than the groove (1) of bottom.The groove of checker brick (1) above when building chamber of hot-blast stove by laying bricks or stones just in time is sitting on the convex edge (2) of following checker brick, to prevent the checker brick dislocation.In order to reduce the contact area of checker brick between laterally, in the outer on checker brick top six equally distributed small lugs (3) are arranged, making has certain distance between the checker brick outer wall.When building chamber of hot-blast stove by laying bricks or stones, closely arrange six checker brick (as shown in Figure 2) around each checker brick with this checker brick.The polygon vertical channel that small lugs (3) can make the arc of checker brick outer wall form interconnects, to strengthen the heat exchanging process of regenerator.Because the horizontal contact between each checker brick is the contact of the point between the small lugs (3), the dead band of also just having eliminated interchange of heat.Make every m ³The heating surface that checker brick had, only less than spherical checker brick, and than employed general checker brick are high more than 30% at present.This checker brick can be formed the vertical channel of two kinds of passes, i.e. the polygon vertical channel formed of the arc of circle (or polygon) vertical channel of being made up of the checker brick endoporus and checker brick outer wall.As shown in Figure 2.
