Abstract

The invention discloses a movable dust collecting cover having movable doors of a blast furnace. A lower gas exhaust pipe is arranged on the upper part of a gas collecting cover; an upper gas exhaust pipe is arranged above the lower gas exhaust pipe; a plug board rack is arranged on the middle part of the upper gas exhaust pipe; a plug board is fitted to a slot in the plug board rack; the lower end of the upper gas exhaust pipe is provided with a pipeline edge; a gas pipe sleeve is arranged at the lower end of the upper gas exhaust pipe in a sleeved manner; the gas pipe sleeve is supported by the pipeline edge at the lower end of the upper gas exhaust pipe; the diameter of the lower part of a cylinder is great, and the diameter of the upper part of the cylinder is small; a cylinder sleeve is arranged on the upper part of the cylinder in the sleeved manner; a bearing is arranged between the upper part of the cylinder and the cylinder sleeve; the two ends of each of two connecting rods are separately connected to a gas collecting cover and the cylinder sleeve; a movable door shaft is arranged at the left upper side each of the two movable doors; a handle is arranged at the right upper side of each of two movable doors; circular holes for allowing the movable door shafts to pass through are formed at left lower sides of the front wall and the rear wall of each gas collecting cover; and the positions, which correspond to the height of the handles, at the front side and the rear side of the right wall of each gas collecting cover are welded with handle hooks.

Description

technical field [0001] The invention relates to a movable blast furnace dust collection cover with a movable door. Background technique [0002] At present, when the slag flowing out of the blast furnace slag port in the smelting industry enters normal temperature from the high temperature state in the furnace, it will solidify due to the temperature drop. The slag opening is blocked. Generally, when the slag opening of the blast furnace is still working, the rice husk is placed near the slag opening, and the rice husk burns for a long time to maintain the temperature. And when the blast furnace slag mouth works, its temperature is high, and paddy chaff will be put near the slag mouth, just need certain space. Due to the need of environmental protection, in order to prevent the exhaust gas from overflowing from the slag material port, the blast furnace slag material port has a dust collection cover. There are two common types of dust collection covers. This kind of dust co...
