Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical devices, and in particular relates to a slag flushing grid screen for a metallurgical furnace melt discharge water quenching system. Background Art

[0002] The slag screen is mainly used in the water quenching system of melt discharge in metallurgical furnaces. After water quenching the high-temperature melt, the slag contains some large pieces of slag due to factors such as slag discharge volume, water volume and slag accumulation in the chute after discharge. These large pieces of slag will cause the slag scoop to get stuck during the scooping process, or get stuck at the discharge port of the slag scoop and the belt of the belt conveyor during transportation, causing belt scratches. Therefore, a screen is added at this location to separate large pieces of slag, so as to effectively reduce the failure of the slag scoop or belt conveyor. Utility Model Content

[0003] The utility model provides a slag flushing screen for a water quenching system of a metallurgical furnace melt discharge, the purpose is to

[0004] To this end, the utility model adopts the following technical solutions:

[0005] A slag flushing grid screen for a metallurgical furnace melt discharge water quenching system, the slag flushing grid screen is installed on the upper part of the slag pool of a slag scooper, and also includes a grid screen support, a grid screen fixing support, a reinforced concrete beam and a rail grid screen;

[0006] A concrete step is cast on the side of the upper part of the slag pool of the slag scoop machine, and the grating support is fixed on the concrete step along the side wall of the slag pool of the slag scoop machine; a reinforced concrete beam is fixed in the middle of the slag pool of the slag scoop machine, the reinforced concrete beam is parallel to the side wall of the slag pool of the slag scoop machine, and the height of the reinforced concrete beam is equal to the concrete step;

[0007] The left end of the slag screen is horizontally connected to the screen support, and the right end of the slag screen is horizontally connected to the reinforced concrete beam;

[0008] The rail screen grid and the screen grid fixed support are fixedly located on the reinforced concrete beam.

[0009] The beneficial effect of the utility model is that large pieces of slag in water-quenched slag can be effectively separated through the rail grating screen, so as to prevent the slag remover from being stuck or the belt of the belt conveyor from being scratched, thereby causing equipment failure.
