Abstract
The utility model relates to a sealing breadth between a material distributor rotary chute sleeve and a sealing box chassis. The utility model is characterized in that a fixed sealing internal ring and a rotary sealing external ring are respectively matched and arranged on the external wall of the sealing box chassis and the internal wall of the rotary chute sleeve; furthermore, a sealing ring consisting of a plurality of layers of elastic stainless steel pieces is arranged between an internal ring and an external ring, thus leading the whole sealing breadth to form the composite sealing integrating a multilayer labyrinth sealing and elastic sealing into a whole. The utility model has the advantages of good elasticity, strong sealing compensation performance, small friction moment, and little power consumption, long service life, thus greatly improving the sealing performance, effectively reducing the nitrogen loss, reducing the cost of the iron refining, and prolonging the service life of the equipment.
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 1-3 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 inner ring of the described sealing width of cloth is fitted on the outer wall of airtight casing chassis, the rotary seal outer ring is fitted on the swivel chute sleeve lining, angle α≤10 of airtight casing chassis outer wall and swivel chute sleeve lining and vertical surface °; The inboard, upper end of fixing seal inner ring and rotary seal outer ring offers a step respectively, is provided with the wear ring of being made up of the multilayer elastic stainless steel substrates between the step; Offer the oil passage that is interconnected on airtight casing chassis outer wall and the fixing seal inner ring, oil passage is connected with step on the fixing seal inner ring; The multilayer elastic stainless steel substrates is by being bolted on the step; When α=0 °, the rotary seal outer ring is by being bolted on the swivel chute sleeve lining.
The beneficial effects of the utility model are: it is being fitted with fixing seal inner ring and rotary seal outer ring respectively and is being provided with the wear ring of being made up of the multilayer elastic stainless steel substrates between inner ring and outer ring on the outer wall on existing airtight casing chassis and on the swivel chute telescopic inwall, thereby the whole sealing width of cloth has formed the compound seal that multi-layer type labyrinth seal and metallic contact are sealed into one, has good springiness, sealing compensation is strong, moment of friction is little, consumption of power is few, outstanding advantage such as long service life, thereby improved sealing property greatly, reduced the consumption of nitrogen effectively, ironmaking cost is reduced, and prolonged the work-ing life of equipment.
