3. discharging fume, to have to pass through the operating space of blast-furnace man upwards emptying again in dirt path, and flue dust spreads in intermediate frequency furnace working region and top, produces poison gas and dust in a large number, expands Polluted area, the health of severe contamination working environment, harm worker.Therefore, in line flue dust mode should be eliminated as early as possible.
In order to solve clarifying smoke problem, technical staff by analysis and design, devises a kind of early stage bell-jar and receives flue dust device.This device can move with fire door, is positioned at the top of fire door during work, serves certain receipts flue dust effect, but its outstanding shortcoming is:
1. directly affect the interpolation of furnace charge, by workman, bell-jar must be received flue dust device time reinforced and push open, otherwise just can not feed in raw material, manually bell-jar must be received flue dust device when collect flue dust and retract, and cover fire door, just can play flue dust collecting effect.But actual conditions are, in the whole process of intermediate frequency furnace melting, flue dust maximum period all appears at intermediate frequency furnace and feeds in raw material in process, and now bell-jar is received flue dust device and must be removed fire door, and it does not play a part to receive flue dust on the contrary; And formal melting period flue dust produces relatively less, after melting completes, during fluid, flue dust is less, and this period bell-jar is received flue dust device and manually retracted above fire door, gathers dust and just works, remove again after melting completes during fluid, trivial operations.
2., if bell-jar receipts flue dust device does not purify poison gas, directly emptying, wider secondary pollution will be caused.In addition, the design comparison of general anode assembling intermediate frequency furnace table own is narrow, after increasing bell-jar receipts flue dust device, will occupy very large working space, make in table region crowded to capacity in a jumble.
