Abstract
The utility model relates to a sealing frame arranged between a distributor rotary chute sleeve and an air-tight box body. The sealing frame has the structure that a sealing seat is arranged at the outer circular column surface of a chassis of the air-tight box body, and the inner circular column surface of the rotary chute sleeve is assembled with a rotary seal ring. The sealing surface of the fixed sealing seat is spherical surface, and the sealing surface of the rotary seal ring is conical surface, wherein the spherical surface is tangential to the conical surface. A sealing part of the conical surface is coned to be welded with an abrasion resistant alloy, and meantime the upper part of the rotary seal ring is provided with a pretension spiral spring and an autocompensation spiral spring. The utility model has the advantages of strong abrasion resistant performance, favorable autocompensation performance, excellent sealing effect and long service life; therefore, the sealing property is greatly enhanced, the consumption of nitrogen is effectively reduced, the iron-smelting cost is reduced and the service life of devices is extended.
Description
Affiliated technical field
The utility model relates to the support equipment of distributor, specifically refers to the sealing width of cloth between distributor swivel chute sleeve and airtight casing.
Background technology
Distributor is the main support equipment of metallurgy industry blast furnace, leave the air cleft of 1-2 millimeter between its airtight casing and the swivel chute sleeve, in order to stop that the coal gas ash in the blast furnace enters, common employing charges into compressed nitrogen and reaches sealing function in airtight casing, and the nitrogen consumption is 100-300m
3Not only the nitrogen consumption is big for this sealing means of/h, the cost height, and also sealing function is poor.
Summary of the invention
The purpose of this utility model has been to provide a kind of consumption that can not only effectively reduce nitrogen, reduces the sealing width of cloth that ironmaking cost can improve sealing property simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is:, the sealing width of cloth between distributor swivel chute sleeve and airtight casing, the fixing seal seat of the sealing width of cloth is fitted on the external cylindrical surface on airtight casing chassis, and rotating seal ring is fitted on the swivel chute telescopic inner cylinder face; The trim of fixing seal seat is a sphere, the trim of rotating seal ring is a cone surface, cone surface and sphere are tangent, and the sealing position on cone surface awl is welded with wear resistant alloy, are provided with pretension and compensation whisker automatically simultaneously between the top of rotating seal ring and swivel chute sleeve chassis; Airtight casing offers oil passage on the chassis, and the cavity top that forms between oil passage and rotating seal ring and the fixing seal seat is connected; Described pretension and automatic compensation whisker are uniformly distributed along the circumference between the top and swivel chute sleeve chassis of rotating seal ring, and quantity is 8-16; The external cylindrical surface top of rotating seal ring is provided with the packing seal ring; The material of described fixing seal seat is a high hardness alloy.
The beneficial effects of the utility model are: the utility model is fitted with the fixing seal seat on the external cylindrical surface of airtight casing chassis, on swivel chute sleeve inner cylinder face, be fitted with rotating seal ring, fixing seal seat trim is a sphere, the rotating seal ring trim is a cone surface, sphere and cone surface are tangent, and sealing position awl is welded with wear resistant alloy on cone surface, be provided with pretension simultaneously on rotating seal ring top and compensate whisker automatically, thereby it is strong to the utlity model has wear resisting property, automatically compensation performance is good, good sealing effect, advantages such as long service life, thus sealing property improved greatly, reduced the consumption of nitrogen effectively, ironmaking cost is reduced, and prolonged the work-ing life of equipment.
