Description
Technical field
This utility model belongs to air stove technical field in iron-smelting process, particularly to a kind of 19 hole 25mm checkerwork cell diameter lattice
Sub-brick and stacking method.Particularly relate to high efficiency, low cost heat storage, it is adaptable to high-temperature thermal storage type exchanger and the storage of heat-exchanging furnace
Hot cell.
Background technology
Along with the dedusting technology progress of coal gas used by Combustion of Hot Air Furnace, the pollution of checker brick in regenerator is reduced, for obtaining
Obtaining bigger heating surface, the direction that the hole of checker brick radially reduces is developed.The small-aperture lattice brick series of exploitation at present is main
There are 7 holes, 19 holes, 31 holes, 37 holes and 61 holes etc..The commonly used checker brick profile of air stove is positive six prisms, from aperture φ
The 7 hole bricks of 42mm, to the 19 hole bricks of φ 30mm, progressively develop into the 37 hole bricks of φ 28mm, φ 22mm.Along with aperture reduces monolithic
The complete hole count of brick is consequently increased, and the volume and weight of monolithic brick is consequently increased.
Although 37 hole bricks are owing to checkerwork cell diameter is little, improve heating surface (area) (HS, but owing to the volume of its monolithic brick increases so that
Manufacture difficulty is high, fabrication yield is low, builds difficulty by laying bricks or stones and strengthens, not only causes checker brick price to increase, and comprcssive strength and body
The physical and chemical indexs such as long-pending density are also deteriorated.
Summary of the invention
The purpose of this utility model is to provide a kind of 19 hole 25mm checkerwork cell diameter checker brick and stacking methods, solves system
Make the problem that difficulty is higher.The heating surface of checker brick can be effectively ensured, reach to control whole height and the grid of air stove
The purpose of brick use cost.
A kind of 19 hole 25mm checkerwork cell diameter checker brick, including 1,19 manholes of brick body 2,12 half of positive hexagonal prism
Manhole 3 and 6 1/3 manholes 4.19 manholes 2 divide three ring distributions, the first ring from inside to outside from brick body 1 center
For RC 1 manhole 2 of brick body 1, the second ring is the most equally distributed 6 manholes 2, and the 3rd ring is positive six
Limit shape is uniformly distributed 12 manholes 2, and outer surface is semi-circular through hole 3 or 1/3 manhole 4, and brick body 1 upper surface has uniformly
Three the circular grooves 6 being along the circumferential direction evenly distributed, lower surface has corresponding round boss 5.
The diameter of each through hole is identical, and pore diameter range is between 25～27mm.
The pitch of holes of each through hole is identical, and scope is between 35～45mm.
Boss 5 be shaped as round platform wide at the top and narrow at the bottom, the shape of groove 6 is all the circular conical surface wide at the top and narrow at the bottom, but in size
Bigger than boss 5 2～5mm.
The stacking method of a kind of 19 hole 25mm checkerwork cell diameter checker brick, the brick body 1 with through hole identical when polylith is stacked
Time together, between the rib that every two blocks of checker brick contact, leave the gap of 8～10mm, make the every two pieces of grid between parallel surface
Semi-circular through hole 3 on brick constitutes 3 manholes 2, makes the diameter of all through holes in whole plane identical, and each leads to
Spacing between hole is equal.Between adjacent two layers checker brick, the fissure of displacement is built by laying bricks or stones, with the crossing center of every three pieces of brick body 1 for upper strata grid
The placement center of brick, then six ribs of upper strata checker brick are distributed on three blocks of checker brick of lower floor the most two-by-two, upper strata checker brick
Lower surface on three boss 5 groove 6 just at lower floor's checker brick upper surface in, such stacking structure makes checker brick
Between adjacent layer, mutually locking forms stable overall structure, and can to absorb self volume swollen the gap between checker brick
Swollen.Checker brick checkerwork cell on whole air stove height and in plane is uniformly distributed and makes checker brick be heated evenly, and circulation is at each lattice
Air-flow in hole is uniform, the effective pressure loss regulating gas, makes the unit volume heating surface of checker brick increase.
The utility model has the advantage of, overall structure is uniform, and manufacture difficulty is low, solves big the asking of pressure loss
Topic, gas flowfield is uniform, improves the heating surface of checker brick, reduces the use cost of air stove heat storage, meets energy-conservation
Use requirement with the high-efficient hot air furnace of environmental protection.

Detailed description of the invention
Fig. 1～Fig. 5 is detailed description of the invention of the present utility model
A kind of 19 hole 25mm checkerwork cell diameter checker brick, brick body 1 and 19 be distributed in brick body of positive hexagonal prism are vertical
The through hole 4 of the complete circle through hole on direction 2,12 3,6 1/3 circles of semicircular through hole, manhole aperture is 25mm,
Complete manhole 2 divides position three ring inside and outside checker brick center, and 12 through holes of outer shroud are parallel to positive hexagonal prism
Six straight flanges, be evenly distributed according to 3, every limit through hole, the angle of center, hole and the checker brick line of centres is divided into 30 °, middle
6 through holes of ring are divided equally by every 60 ° in a circumferential direction, and innermost ring is the center that 1 manhole is positioned at brick body 1, and positive six
Prism is by being distributed with 5 complete manholes 2 on two corner angle lines at center, and semicircular through hole 3 is positive six
Being distributed two on each rib of prism brick body 1, the through hole 4 of 1/3 circle is positioned on six corner angle of positive hexagonal prism brick body 1,
The center distance of each through hole is equal, and pitch of holes is 40mm, and all of through hole is up-small and down-big bellmouth, upper and lower aperture difference
For 2mm, regular prism brick body 1 upper surface has three circular grooves 6, and lower surface has the boss 5 that corresponding three are circular, recessed
Groove 6 and boss 5 are circle and occupy the area of two complete checkerwork cells, and boss 5 be shaped as round platform wide at the top and narrow at the bottom, groove
The shape of 6 is all the circular conical surface wide at the top and narrow at the bottom, but 2mm bigger than boss 5 in size, it is ensured that both can lock mutually.
When checker brick are piled up when, in order to ensure the overall structure stability of heat storage, checker brick center, upper strata
It is positioned at during three blocks of checker brick of lower floor intersect in the heart, when lower floor's checker brick are stacked upon, the rib that every two blocks of checker brick contact
Between leave the gap of 8mm, make the semi-circular through hole on each two checker brick between parallel surface constitute 3 combination through holes 7, three
The center that block checker brick corner angle are crossed to form also forms a combination through hole 7, and three boss 5 of upper strata checker brick lower surface are just
It is positioned at well in the groove 6 of lower floor's checker brick upper surface, the checker brick the piled up checkerwork cell on whole heat storage cross section so formed
It is evenly distributed, and the distance between each through hole is the most identical.
When being embodied as, checker brick are piled up in chamber of hot-blast stove according to said structure, upper strata checker brick and lower floor's grid
Being fixed by groove 6 and boss 5 between brick, the upper and lower surface checkerwork cell of each layer of checker brick is evenly distributed, uniform when air-flow passes through
Distribution, makes each checkerwork cell inner surface of heat storage be heated evenly, and it is excessive not result in heat storage local gas pressure, thus add
The big effective rate of utilization of heat storage, thus improve pathogenic wind-warm, make the rate of heat exchange of air stove increase substantially, and this structure
Reduce the manufacture difficulty of checker brick, decrease the cost of processing and fabricating, and control the whole height of air stove.
