Description
Technical field
It the utility model is related to a kind of industrial furnace, more particularly to a kind of structure on the arch kiln top of Industry Tunnel Kiln.
Background technology
Tunnel cave is the Thermal Equipment that the continous way of modernization is burnt till, and is widely used in the industries such as ceramics, building materials and abrasive material
In.Tunnel cave is usually a long linear tunnel, and fixed wall and vault are arranged at its both sides and top, and the gravity of vault leads to
Arch springing to be crossed to be delivered on wall, common vault is built by normal refractory brick and overarched, on tunnel cave width, vault
Two-side supporting is provided with the inclined-plane being connected with being built into the key brick of vault on skew block, on skew block, and skew block is arranged on
On wall, such vault construction is relatively easy, practical, but correspondingly, is also easy to be damaged, because of temperature change and hot on kiln top
In the case of swollen shrinkage, the high temperature in the course of work can make vault by squeezing, and terminate in the course of work, meeting after furnace temperature declines
Shrink, so as to cause vault repeated deformation, the joint sealing material between key brick also can be deformed or peeled off therewith, and key brick is mutual
And the attachment structure between key brick and skew block has destroyed trend, and can cause under kiln top sealing heat-insulating property
Drop.In order to change this situation, some manufacturer productions trapezoidal ceiling brick in section, according to the arc on institute's built tunnel arch of furnace top
Size determines the width of the top and bottom of trapezoid cross section ceiling brick, to be improved to kiln top attachment structure, although this is than general
The refractory brick using effect of logical cuboid will get well, but its versatility is deteriorated, and to determine special kiln for each tunnel cave
Dome brick, manufacturing cost is high, and the ceiling brick for also being difficult to be fitted on same size size, and adjacent two arch of this structure are changed in later maintenance
The relative connection surface of dome brick is parallel to each other, and pointing is more hard to keep.
