Problems solved by technology

[0002]The exhaust chimneys of the existing high-temperature push plate furnaces are mostly designed at the top brick of the furnace, and it is necessary to open a smoke exhaust hole on the top brick, and the hole will affect the top brick. The stability at high temperature may even cause the top brick to crack and sink at high temperature. When the top brick sinks to a certain extent, it will affect the passability of the product, which will cause the situation of the arch furnace

Embodiment 1

[0028] Such as Figure 1 to Figure 6 As shown, the partition beam top brick 2, the bottom of the partition beam top brick 2 side is provided with a partition 21, and the other side of the partition beam top brick 2 is provided with a smoke exhaust groove 22, and the smoke exhaust groove 22 is connected with the partition beam top brick 2 The top and bottom are connected.

[0029] The smoke exhaust hole formed by the smoke exhaust groove 22 communicates with the flue gas passage 11 of the push plate furnace 1 to discharge the smoke inside the push plate furnace 1 .

[0030] The original top brick is designed as two symmetrical partition beam top bricks 2, and the structure is improved, and a semicircular smoke exhaust groove 22 is set on the opposite surface of the partition beam top brick 2, and the partition beam that is fired separately The top brick 2 has high strength and is not easy to crack at high temperature. After the smoke exhaust hole was opened in the center of t...

Embodiment 2

[0035] On the basis of the above embodiments, the bottom of the beam top brick 2 is provided with a smoke guide groove 23 , and the smoke guide groove 23 communicates with the smoke exhaust groove 22 .

[0036] The smoke guide groove 23 is conical, forming a larger smoking opening, effectively introducing the smoke into the smoke exhaust hole, the smoke exhaust speed is fast, and the smoke exhaust performance is better than the smoke exhaust hole set on the top brick, and has no effect on the strength .

Embodiment 3

[0038] On the basis of any one of the above-mentioned embodiments, a positioning step 27 is provided between the smoke guide groove 23 and the smoke exhaust groove 22 . The positioning step 27 is convenient for installing a smoke exhaust pipe in the flue gas passage 11, and the smoke exhaust pipe is inserted into the smoke exhaust pipe to protect the insulation layer. One end of the smoke exhaust pipe can be inserted into the smoke exhaust hole to reduce the leakage of smoke to the insulation layer.

Abstract

The invention relates to a push plate furnace, in particular to a partition beam top brick. A partition plate is arranged at the bottom of one side of the partition beam top brick, a smoke exhaust groove is formed in the other side of the partition beam top brick, and the smoke exhaust groove communicates with the top and the bottom of the partition beam top brick. The partition beam top brick provided by the invention is simple in structure, does not need to be perforated, effectively solves the problem of cracking, and is good in structural strength, the top of a hearth does not sink after the partition beam top brick is mounted, and the partition beam top brick is convenient to mount.

Description

technical field [0001] The invention relates to a pusher furnace, in particular to a beam top brick and an exhaust device for a pusher furnace. Background technique [0002] Exhaust chimneys of existing high-temperature push plate furnaces are mostly designed at the top brick of the furnace, and smoke exhaust holes need to be opened on the top brick. In case of cracking and sinking, when the top brick sinks to a certain extent, it will affect the passability of the product, which will cause the situation of the arch furnace. Contents of the invention [0003] In order to solve the above problems, the present invention provides a roof brick without openings on the roof brick, has good structural strength, and the top of the furnace will not sink. The specific technical solution is: [0004] The top brick of the partition beam, the bottom of one side of the top brick of the partition beam is provided with a partition, the other side of the top brick of the partition beam is...
