By adopting the technical scheme, the positioning step is convenient for installing the smoke exhaust pipe in the smoke channel, and the smoke exhaust pipe is inserted into the smoke exhaust pipe to protect the heat insulation layer. One end of the smoke exhaust pipe can be inserted into the smoke exhaust hole, so that the smoke leakage to the heat insulation layer is reduced.
Furthermore, a smoke suction groove is formed in the bottom of the partition beam top brick, and a smoke guide groove is formed in the top of the smoke suction groove.
By adopting the technical scheme, the smoke suction groove is used for enlarging the smoke suction port, the bottoms of the two partition beam top bricks are not contacted, the condition of mutual extrusion caused by thermal expansion is effectively avoided, and the partition beam top bricks are protected.
Furthermore, the bottom of the top brick of the partition beam is provided with a through groove.
By adopting the technical scheme, the height inside the hearth is increased through the grooves, the sintered objects can pass through the grooves conveniently, the collision with sintered products is effectively avoided, and the beam top brick is effectively protected.
The push plate furnace exhaust device comprises two partition beam roof bricks, the two partition beam roof bricks are symmetrically arranged, the smoke exhaust grooves form smoke exhaust holes, the smoke exhaust holes are communicated with a smoke channel, two ends of each partition beam roof brick are arranged on side refractory bricks of a hearth, and top refractory bricks are arranged on the partition plates.
Compared with the prior art, the invention has the following beneficial effects:
the partition beam top brick provided by the invention has a simple structure, does not need to be provided with a hole, effectively solves the cracking problem, has good structural strength, does not sink at the top of a hearth after being installed, and is convenient to install.
The push plate furnace exhaust device provided by the invention realizes smoke discharge by the roof bricks with holes formed by the symmetrical partition beam roof bricks, has good structural strength, and can prevent the top of the hearth from sinking.
