In Combined brick for burner nozzle described in the utility model, the upper surface of described left quarl and right quarl contacts with the lower surface of the spacing refractory brick of convex-shaped and forms step snap close.
In Combined brick for burner nozzle described in the utility model, the lower surface of described left quarl and right quarl contacts with the upper surface of the spacing refractory brick of lower convex and forms step snap close.
In Combined brick for burner nozzle described in the utility model, the upper surface of the spacing refractory brick of described lower convex, the spacing refractory brick of convex-shaped, left quarl and right quarl is radially provided with boss, and lower surface is provided with the groove corresponding with described boss.
In Combined brick for burner nozzle described in the utility model, described groove and boss form circular glossal canal snap close.
Implement Combined brick for burner nozzle of the present utility model, there is following beneficial effect:
1, circumferential employing step locking form of the present utility model, can make two wall bricks between spout become as a whole, avoid because high velocity air in spout passage washes away the wall brick on spout both sides, wall brick is produced loosening, cause burner nozzle to be subjected to displacement, to be out of shape.
2, the locking form that radially can adopt tongue and groove of the present utility model, avoids burner wall brick because of harmomegathus or the airflow scouring of brick, and to circular passage or precombustion chamber tilt.
3, the utility model Nozzle combination brick, good sealing effect, Stability Analysis of Structures, the life-span is long, has good economic benefit and social benefit.

The specific embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As shown in Fig. 1-Figure 12, the utility model Combined brick for burner nozzle, comprises and is arranged on the nozzle 7 spacing refractory brick 1 of lower convex, the spacing refractory brick 5 of convex-shaped, a plurality of left quarl 2,3,4 and a plurality of right quarl 2a, 3a, 4a around.
The cross section of the spacing refractory brick 1 of lower convex and the spacing refractory brick 5 of convex-shaped is " protruding " shape, and it has two kinds of forms, and step place can be arranged to slope, as shown in Fig. 2, Fig. 3 and Fig. 9.
The upper surface of left quarl 2,3,4 and right quarl 2a, 3a, 4a contacts with the lower surface of the spacing refractory brick 5 of convex-shaped and forms step snap close.The lower surface of left quarl 2,3,4 and right quarl 2a, 3a, 4a contacts with the upper surface of the spacing refractory brick 1 of lower convex and forms step snap close.The upper and lower left quarl 2,4 at two ends and the shape of right quarl 2a, 4a are corresponding with the spacing refractory brick 1 of lower convex and the spacing refractory brick 5 of convex-shaped, so they are slightly different with right quarl 3a from the left quarl 3 in intermediate layer.The circumferential employing step locking form of nozzle 7 modular tiles, can make two wall bricks between spout become as a whole, avoid because high velocity air in spout passage washes away the wall brick on spout both sides, wall brick is produced loosening, cause burner nozzle 7 to be subjected to displacement, to be out of shape.
The upper surface of the spacing refractory brick 1 of lower convex, the spacing refractory brick 5 of convex-shaped, left quarl 2,3,4 and right quarl 2a, 3a, 4a is radially provided with boss 8, and lower surface is provided with the groove corresponding with boss 89.Groove 9 in the present embodiment and boss 8 are ligulate, form the locking of concavo-convex circular glossal canal.The locking form that radially adopts tongue and groove of nozzle 7 modular tiles, avoids burner wall brick because of harmomegathus or the airflow scouring of brick, and to circular passage or precombustion chamber tilt.
The utility model in use, left quarl 2,3,4 and right quarl 2a, 3a, 4a can not be used by the unified reversing of position in left and right, the spacing refractory brick 5 of convex-shaped and the spacing refractory brick of lower convex shape can not be unified up and down reversing of position and use, the utility model can, according to the length of the size of burner diameter and nozzle 7, determine to lay bricks quantity.
It is to be noted, the necessary supporting use of the utility model, when building burner nozzle 7 by laying bricks or stones, refractory brick is built and is put together mutually, sturdy and durable, good airproof performance, the thermal change of not catching a cold, nozzle 7 convergent-divergents and the poor impact of working condition, nozzle 7 is air tight, run wind, collapse, displacement, reduces maintenance frequency.Give Reducing Cost in Enterprises, there is huge economic benefit and social benefit.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
