Abstract
The utility model relates to the auxiliary equipment of a blast furnace top chute distributing device, particularly a sealer for an airtight box of a chute stock distributing device. The airtight box of the chute stock distributing device and a rotating chute sleeve barrel use a nitrogen sealing ring for sealing, and the entry of gas ash can be effectively prevented. The sealing effect is good, and the friction of a sealing surface is small.
Description
Affiliated technical field
The utility model relates to the support equipment of blast furnace furnace roof channel distributor, specifically refers to the airtight casing tightness system of a kind of channel distributor.
Background technology
Blast furnace furnace roof channel distributor is the main support equipment of metallurgy industry blast furnace, leave the 1-2 mm clearance between the chassis of its airtight casing and the swivel chute sleeve, in order to stop that the coal gas ash in the blast furnace enters airtight casing, common employing charges into compressed nitrogen and reaches sealing function in airtight casing, but this sealing means can not effectively stop entering of coal gas ash, and sealing effectiveness is poor.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, the airtight casing tightness system of the channel distributor of good seal performance.
The technical scheme that its technical problem that solves the utility model adopts is: the airtight casing tightness system of a kind of channel distributor, this device in the barrel on airtight casing chassis, offer annular gas storage chamber and be connected with annular gas storage chamber go out vent hole and air inlet through hole, go out vent hole and be communicated with gap between swivel chute sleeve and the airtight casing chassis, the air inlet through hole is connected with inlet mouth; Described gas storage chamber is annular and is opened in airtight casing chassis barrel internal upper part.
The beneficial effects of the utility model are: the utility model offers annular gas storage chamber and the air inlet through hole that is connected with annular gas storage chamber and goes out vent hole and go out vent hole and is communicated with gap between swivel chute sleeve and the airtight casing chassis in the barrel on existing airtight casing chassis, the air inlet through hole is connected with inlet mouth, when when inlet mouth charges into compressed nitrogen continuously, gas can enter the gas storage chamber by the air inlet through hole, enter gap between swivel chute sleeve and the airtight casing chassis by the vent hole that goes out that is communicated with the gas storage chamber then, and be distributed between two trims, form annular air curtain, can effectively stop entering of coal gas ash, good seal performance, and the trim friction is little.
