Abstract
The utility model discloses a combined lattice brick for a multi-section hot blast stove. The combined lattice brick comprises a brick body; top holes are formed in the top surface of the brick body; bottom holes are formed in the bottom surface of the brick body; and each top hole is communicated with at least two bottom holes. The top holes and the bottom holes with two different apertures can be used for connecting two different types of lattice bricks respectively, so that lattice bricks of the multi-section hot blast stove can be in transition connection with one another during arrangement, the smooth flowing of air in lattice brick channels is ensured, and the utilization efficiency of heat energy is enhanced as the different lattice bricks can be used for heat transfer and storage in different height directions of the multi-section hot blast stove.
Description
Technical field
The utility model relates to a kind of checker brick, is specifically related to the combined checker brick of a kind of multi-stage type hotblast stove.
Background technology
Checker brick are media of hotblast stove transferring heat.At present, the mode that all adopts a kind of checker brick to be deposited in chamber of hot-blast stove is conducted heat and accumulation of heat.
Chamber of hot-blast stove has different heat transfer characteristics at different heights, high-temperature zone, regenerator top is strong heat transfer zone, heat transfer type is radiation and transmission of heat by convection, the heat transfer type at regenerator middle part main still radiation and two kinds of heat transfer forms of convection current, the main heat transfer type of regenerator bottom cold zone is transmission of heat by convection.Therefore, the mode that adopts a kind of checker brick to be deposited in chamber of hot-blast stove can not be conducted heat and accumulation of heat fully.Therefore, under the condition of the conditions permits such as gas quality and checker brick processing and manufacturing, the thicker checker brick of the large equivalent depth of heat storage capacity should be adopted in top, and the thinner checker brick of equivalent depth are adopted in the bottom, adopt this mode to reach the purpose of better heat transfer and accumulation of heat.
The multi-stage type hotblast stove designs according to regenerator different thermal characteristics on short transverse, and it is the different checker brick of set direction at various height.Owing to being dissimilar checker brick, each through hole is difficult to aligned stack, guarantees that air-flow flows unimpeded in the checker brick passage.Therefore, solve the connection of multi-stage type stove fillings when putting and just become a urgent problem.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of multi-stage type hotblast stove combined checker brick, is used for connecting two kinds of dissimilar checker brick of regenerator upper and lower part, solves stove fillings and puts the transition connectivity problem.
For achieving the above object, the utility model provides following technical scheme: a kind of combined checker brick, comprise the brick body, and brick body top surface is provided with the top through hole, and brick body lower surface is provided with the bottom hole, and each top hole is connected with at least two bottom holes.
Described each top hole is connected with three bottom holes.
Hole aperture, described top is greater than hole aperture, bottom.
Described top hole or bottom hole cross section can be circle, blossom type and regular polygon.
Described top surface is provided with groove, and lower surface is provided with tongue.
Described checker brick are regular hexahedron.
The beneficial effects of the utility model are: the utility model is provided with top hole and bottom hole on the brick body, be used for respectively connecting two kinds of dissimilar checker brick, solve stove fillings and put transition problem, guarantee air-flow unimpeded flowing in the checker brick passage.Realized that the multi-stage type hotblast stove adopts different checker brick to conduct heat and accumulation of heat in the different heights direction, has improved the utilising efficiency of heat energy.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Fig. 1 is the top view of the utility model embodiment 1, Fig. 2 is the A-A face sectional view of Fig. 1, as shown in the figure, the combined checker brick of the present embodiment, comprise the brick body, be provided with top hole 1 along brick body top surface, be provided with bottom hole 2 along brick body lower surface, each top hole 13 is connected with three bottom holes 2 through the middle part, and top hole 1 aperture is greater than bottom hole 2 apertures.
As shown in Fig. 1,3, the quantity of the combined checker brick tops hole 1 of the present embodiment is 19, and the quantity of bottom hole 2 is 72.
When hotblast stove is in state of combustion, high-temperature flue gas flows to the top hole 1 of these combined checker brick by regenerator top checker brick, again from top hole 1 through the middle part 3 shuntings to 3 bottom holes 2, and flow out from bottom hole 2, enter regenerator bottom checker brick.When hotblast stove was in ventilation state, cold wind flow to the bottom hole 2 of these combined checker brick by regenerator bottom checker brick, then 3 accumulated 1 strand of air-flow from bottom hole 2 through the middle part, flowed out from top hole 1, entered regenerator top checker brick.
In the present embodiment, the cross section of described top hole 1 and bottom hole 2 is circular; Certainly, the cross section of top hole 1 and bottom hole 2 can also be blossom type, regular polygon.
As shown in Figure 1, 2, 3, this combined checker brick top surface is provided with groove 4, can locate with the top checker brick, and lower surface is provided with tongue 5, can locate with bottom lattice brick.
Fig. 4 is the top view of the utility model embodiment 2, and Fig. 5 is the A-A face sectional view of Fig. 4, and as shown in the figure, the combined checker brick of the present embodiment are compared with embodiment 1, and difference is that the quantity of top hole 1 and bottom hole 2 is different from embodiment 1.As shown in Fig. 4,6, the quantity of the combined checker brick tops hole 1 of the present embodiment is 16, and the quantity of bottom hole 2 is 37.
Explanation is at last, above preferred embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is described in detail by above preferred embodiment, but those skilled in the art are to be understood that, can make various changes to it in the form and details, and not depart from the utility model claims limited range.
