DUST-FREE DRY ASH DISCHARGE SYSTEM AND CONVERTER FLUE GAS PURIFICATION SYSTEM Russian patent published in 2023 - IPC B65G65/46 C21C5/40 

FIELD: metallurgy.

SUBSTANCE: invention can be used in systems for dust-free removal of dry ash and purification of converter flue gases. The system includes an ash pit, a main pipeline for ash removal and an elevator device for ash removal, which contains the first and the second screw conveyors for ash and a lifting drive unit. The inlet of the first screw conveyor is connected to the main pipeline using a retractable hose, the discharge hole of the first screw conveyor is connected to the inlet of the second screw conveyor, the second screw conveyor transports ash down and, together with the first screw conveyor, forms a single structure to which the lifting drive unit is connected.

EFFECT: invention ensures environmental protection due to the lifting drive unit, which prevents the infiltration of secondary dust during ash removal, and also ensures a stable and reliable ash transportation process without dry ash getting stuck in the pipeline.
