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 and 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 hole 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-sect...

Abstract

The invention provides a grating plate device of an air heating furnace. The grating plate device comprises supporting columns and a grating plate, wherein the grating plate is arranged on the supporting columns; a plurality of holes formed in the grating plate on the supporting faces of the hollow supporting columns are connected with ventilating holes outside the supporting faces of the hollow supporting columns. According to the application, certain holes in the supporting faces of the hollow supporting columns are connected with the adjacent ventilating holes positioned outside the supporting faces of the columns in a manner of horizontal pore channels, so that the problem that the columns block the holes of the supporting grating plate is easily solved, and the structure and the intensity of the supporting grating plate are not influenced; a beam structure is basically omitted, so that any connection between every two supporting grating plate components is avoided; therefore, the structure stress between the supporting grating plate components fixed by a beam in the prior art is also eliminated; the supporting grating plate and the columns are only purely supported with each other without bolt connection; the structure stress between the supporting grating plate and the columns is also eliminated.

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...
