[0002] Grate bricks are generally installed behind the burner of a regenerative heating furnace to support and reinforce the ceramic regenerative material.

[0003] The existing technology has the following problems:

[0004] When stacking a kiln, the grate bricks are generally stacked one by one, and then cement is filled between adjacent grate bricks to connect the grates together. However, in actual use, since most grate bricks are regular rectangular blocks, the stability is poor when connected with cement.

[0005] To this end, we proposed a refractory ball grate brick for heat storage chamber to solve the above disadvantages. Utility Model Content

[0006] The utility model aims to solve the problem that most of the grate bricks in the prior art are regular rectangular parallelepipeds and have poor stability when connected with cement in actual use, and proposes a refractory ball grate brick for a heat storage chamber.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A refractory ball grate brick for a heat storage chamber comprises a brick body, the surface of which is provided with grate holes, the upper surface of which is provided with strip grooves, the lower surface of which is provided with strip filling bodies, and the height of the strip filling bodies is half of the height of the strip grooves.

[0009] Preferably, a through hole is formed through the surface of the brick body, and the through hole is filled with an insulation board.

[0010] Preferably, the insulation board is made of asbestos board or extruded polystyrene board.

[0011] Preferably, side grooves are provided on the side surfaces of the brick body.

[0012] Preferably, the interior of the brick body is filled with a steel wire mesh.

[0013] Preferably, the side surface of the brick body is provided with anti-slip bumps.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The utility model provides a brick body, a grate hole, a strip groove and a strip filling body. When stacking, the strip filling body at the bottom of the grate brick of the upper layer is aligned with the strip groove on the upper surface of the grate brick of the lower layer and inserted into the strip groove. Since a certain space is reserved between the strip filling body and the strip groove, the construction workers can add concrete filler into the strip groove in advance, thereby ensuring the connection strength of the grate bricks and enhancing the connection intimacy and stability between the grate bricks.
