Problems solved by technology

[0002] At present, the hot blast stoves of most blast furnaces use checker bricks as the heat storage carrier. There are generally two types of checker brick support devices: one is an independently supported furnace grate, and each pillar supports a furnace grate board independently. After the grate sub-plate is installed, its upper surface is an integral plane; the structural pillars are easy to tilt and the stability is poor, and the grate sub-plate is subject to a large bending moment due to the cantilever structure. Under the action of force, it is easy to collapse and cause damage to the upper heat storage body, which affects the porosity of the checker brick and the life of the heat storage body
The other is a checker brick support structure with bea

Abstract

The invention provides a checker brick support device of a hot-blast stove and relates to the technical field of heat regenerative hot-blast stoves. The checker brick support device of the hot-blast stove comprises a grate plate and a plurality of support beams for supporting the grate plate, wherein the grate plate is provided with a mounting surface; the support beams are arranged at intervals;clamping fixing structures are arranged between each support beam and the the mounting surface; each clamping fixing structure comprises a positioning part and a clamping part which are matched in aninserted manner; each positioning part is arranged on one support beam; and a clamping part is arranged at the position, opposite to each positioning part, of the mounting surface. According to the checker brick support device of the hot-blast stove provided by the invention, all the components are clamped and fixed to form a whole with a stable structure.

technical field [0001] The invention relates to the technical field of regenerative hot blast stoves, in particular to a checker brick support device for hot blast stoves. Background technique [0002] At present, the hot blast stoves of most blast furnaces use checker bricks as the heat storage carrier. There are generally two types of checker brick support devices: one is an independently supported furnace grate, and each pillar supports a furnace grate board independently. After the grate sub-plate is installed, its upper surface is a whole plane; the structural pillars are easy to tilt and the stability is poor, and the grate sub-plate is subject to a large bending moment due to the cantilever structure. Under the action of force, it is easy to collapse and cause damage to the upper heat storage body, which affects the porosity of the checker bricks and the life of the heat storage body. The other is a checker brick support structure with beams, which is generally compo...
