Problems solved by technology

Because the shape of the grate plate close to the furnace shell is relatively complicated, the structure of its reinforcing rib is correspondingly complicated
However, this device has not made substantial improvements to the transitional grate block (that is, the splitter plate) on the grate plate.

Embodiment 1

[0018] figure 1 with figure 2 Shown is the first embodiment of the grate plate device, a grate plate device for hot blast stoves, including a support column 1 and a grate plate 2, and the grate plate 2 is arranged on the support column 1, and is characterized in that, The supporting column 1 is hollow, and several holes 3 of the grate plate 2 arranged above the supporting surface of the hollow supporting column 1 are connected with the transparent holes arranged outside the supporting surface of the hollow supporting column 1 .

[0019] The bottom of the grate plate 2 has a diameter and a depth that matches the support surface of the pillar and is perpendicular to the through holes of the grate plate.

[0020] The holes 3 on the grate plate 2 above the support surface of the hollow support column 1 are connected with the adjacent transparent holes located outside the support surface of the support column in the form of horizontal channels 4 .

[0021] The cross-se...

Abstract

The invention proposes a grate plate device for a hot blast stove, which includes a support column and a grate plate, the grate plate is arranged on the support column, and several holes of the grate plate are arranged above the support surface of the hollow support column, It is connected with the through hole arranged outside the support surface of the hollow support column. In the application of the present invention, some holes located above the supporting surface of the hollow support column are connected with the adjacent transparent holes located outside the supporting surface of the column in the form of horizontal channels, so as to solve the problem of blocking the support grate by the column very simply. The problem of the hole in the sub-board does not affect the structure and strength of the supporting grate board. The beam structure is fundamentally canceled, which makes no connection between each support grate sub-slab assembly, thus eliminating the structural stress between the support grate sub-slab components fixed together by the cross beam in the past, and the support grate sub-slab There is only a simple support function between the pillars and no bolt connection, thus eliminating the structural stress between the supporting grate plate and the pillars.

Description

technical field [0001] The invention relates to a grate plate device for a hot blast stove or a combustion furnace in the field of metallurgy. Background technique [0002] At present, the most commonly used grate structure for most large and medium-sized blast furnace hot blast stoves is a flat-bottomed grate device with beams. This kind of grate device technology is relatively mature. convenient. [0003] There is a kind of grate board device (patent No. CN2066863U), which cancels the beam and uses a grate board and pillars with reinforcing ribs. It will not block the holes of the grate board, and the single grate board is directly supported independently by the pillars suitable for its own structure, and the bottom of the grate board coincides with the head of the pillar. The pillars have sufficient air intake gaps to ensure the smooth air flow of the grate board and checker bricks. The grate plate and the pillar are two independent structural units to increase the hea...
