Abstract
The utility model provides a dust-sucking flue gas guide sleeve, which comprises a fixed guide sleeve and a vertically-moving sleeve arranged on the outer wall of the fixed guide sleeve. The dust-sucking flue gas guide sleeve is characterized in that a conical surface is arranged along the circumference of the outer side of the bottom of the fixed guide sleeve, and a conical surface is arranged along the circumference of the inner side of the top of the vertically-moving sleeve. After the dust-sucking flue gas guide sleeve moves along with a charging car and is butted with the charging inlet of a coke furnace, when coal is charged into another charging inlet, a flue gas dust pipe guides the flue gas dust produced in the process of coal charging into the dust-sucking flue gas guide sleeve, the flue gas dust is then sucked into the furnace via the charging inlet of the coke furnace, consequently, the flue gas of pulverized coal can be effectively prevented from leaking out, environment pollution is prevented, and meanwhile, the damage of equipment is prevented as well. In addition, since the dust-sucking flue gas guide sleeve adopts a retractable structure, the dust-sucking flue gas guide sleeve can be retracted in order to move along with the charging car when coal does not need to be charged, and can be extended out in order to suck dust and guide flue gas when coal is charged, and the dust-sucking flue gas guide sleeve is simple in structure, good in sealing property and convenient in operation, and therefore is an ideal dust-sucking flue gas guide sleeve.
Description
Technical field
The utility model relates to a kind of cigarette cover of leading, and the cigarette cover is led in particularly a kind of dust suction that is used to push up between dress coke oven and the coal charger, belongs to the coke oven for iron technical field.
Background technology
Coal charger is in the process of coalingging, and coal charger is aimed at coal port, after the startup cover carriage is drawn bell, puts down guide pin bushing and pushes down fire door, starts bulkhgead gate by the flashboard cylinder and puts coal.Yet under gravity, coal can spray from coal port at swollen material of coal port or formation high pressure coal dust flue gas.The dust flue gas of these coals not only can pollute environment, also can cause burning or detonation under hot conditions, and equipment is caused damage.Therefore be necessary prior art is improved.
Summary of the invention
For solving existing coal charger when coalingging, the coal dust flue gas pollutes environment, and equipment is caused the problem of damage, and the utility model provides a kind of dust suction to lead the cigarette cover.
The utility model is finished by following technical proposal: the cigarette cover is led in a kind of dust suction, comprise fixedly guide pin bushing, place the cover that moves up and down of fixing guide pin bushing outer wall, it is characterized in that being provided with the conical surface along circumference in fixing guide pin bushing bottom outside, move up and down the cover inside top be provided with the conical surface along circumference, so that move up and down cover when falling, finish fixing guide pin bushing and move up and down sealing between the cover by the two matched conical surfaces.
At least establish a circle sealing groove on the described conical surface, establish sealing-ring in the sealing groove, with by the conical surface and on sealing groove and the connecting of the sealing-ring and the corresponding conical surface, finish sealing.
The described cover bottom outer wall that moves up and down is provided with the annular girth sheets that adapts with coke oven coal-charging mouth diameter, overlaps when dropping to the coke oven coal-charging mouth so that move up and down, and places on the coke oven coal-charging mouth and stove circle face formation sealing by annular girth sheets.
The described cover top outer wall that moves up and down is provided with connecting rod, and connecting rod links to each other with the transmission rod of outside, moves up and down cover and can move up and down so that make by external force.
The utlity model has following advantage and effect: adopt such scheme, the utility model is being moved with coal charger and with after the coke oven coal-charging mouth docks, when another coal port is coaling, the flue dust that produces by the flue dust pipe process of will coalingging imports dust suction of the present utility model and leads in the cigarette cover, again in the coke oven coal-charging mouth sucks stove, thereby effectively prevent leaking of coal dust flue gas, not only avoided pollution, also avoided the infringement that equipment is caused simultaneously environment.In addition, the utility model has adopted stretching structure, can withdraw when not coalingging and move with entrucking, stretches out also dust suction when coalingging and leads cigarette, and it is simple in structure, and good seal performance is easy to operate, is an ideal dust suction smoke guide device in fact.
