Abstract

[0001] The present application relates to the technical field of steelmaking dust removal, and in particular to an ash discharge valve with a coarse ash crushing function. Background Art
[0002] In the pneumatic conveying system of coarse ash from dry dust removal in steelmaking, high-temperature dust is easily accumulated and attached to the inner wall of the pipeline. This is mainly due to the condensation of dust ash under high temperature, the precipitation of saturated water inside, which causes the dust ash to absorb moisture and become hardened and attached to the wall. When the hardened dust falls in blocks and enters the conveying system, it is then conveyed to the ash discharge valve by the scraper, and further conveyed to the silo pump, which can easily cause the ash discharge valve to get stuck, causing the pneumatic conveying system to fail to operate. At the same time, if more block ash is discharged to the silo pump, it is easy to block the silo pump discharge port when it accumulates in the silo pump, and the ash conveying pipeline is blocked, which brings hidden dangers to the safe and stable operation of the pneumatic ash conveying system.

[0027] This embodiment has a simple structure and a reasonable design. By setting up a crushing mechanism 3 and driving the valve core 13 and the crushing mechanism 3 through the driving mechanism 2, the coarse ash can be crushed to avoid clogging of the ash discharge valve and facilitate transportation at the rear end.
[0028] Specifically, in this embodiment, the valve core 13 and the crushing mechanism 3 are installed on the same transmission shaft 12 and driven by the same driving mechanism 2.
