Abstract
The utility model belongs to improvement of a steelworks hot metal desulphurization injection wellhead gas sealing structure, and especially relates to a hot metal desulphurization injection wellhead overall fully enclosed gas sealing device, which comprises a spray gun tube installed in a platform wellhead, wherein two gas seal rings are arranged on the spray gun tube, a smoke hood with a dust removing air pipe is arranged on the lower part of the gas seal ring, and an erect cylinder is arranged on the platform wellhead, the spray gun tube is located on the axis of the cylinder, the two gas seal rings are fixedly connected in the cylinder, a cover plate which enclosing the upper opening of the cylinder is fixedly connected to the spray gun tube on the upper end of the cylinder. The structure of the gas sealing device is reasonable, the semi-enclosed upper gas seal is changed into a fully enclosed gas seal, so that the diffusion of flue gas can be prevented, the work environment is improved, the service life of the gas seal ring is prolonged, and the maintenance is convenient and safe.
Description
Technical field
The utility model belongs to the improvement of steelworks desulfurizing iron winding-up well head gas seal structure, particularly the whole totally-enclosed air seal set of desulfurizing iron winding-up well head.
Background technology
The state-of-the-art optimizes production technology flow of current modernized steelworks is: hot metal pretreatment (desiliconization of hot metal, desulfurization, dephosphorization)-top and bottom combined blown converter less-slag melting-molten steel furnace external refining-sequence casting and hot delivery and hot charging route.The full dose desulfurization of molten iron is one of them important step.
According to smelting the desulfurization standard-required, driving is placed iron ladle on the chassis of tumbling, and opens to handling station, and tumble and skim in advance, top spray desulfurization, secondary is skimmed, and after the thermometric sampling was qualified, tipping car was opened to the lifting position, the iron ladle lifting.
The winding-up well head at steel desulfurization station is the dedusting of semi-open-type list sealing gland always, and environment protecting is very poor, and flue dust fills the air in the factory building, is badly in need of rectification.
The subject matter that exists is following:
1,1, No. 3 desulfurization station well head sealing glands of 120t converter are because design is unreasonable, at use envelope dirt weak effect.
2, original design sealing gland is because the aperture is less and to divide two-layer be not an integral body and to go up sealing gland be a semi-enclosed sealing gland ring, and spray gun long back slagging scorification duration of service often causes when carrying rifle and draws bad sealing gland so that can't use.
3, because after sealing gland was damaged apart from about 1.5 meters on platform down, there was very big potential safety hazard in each maintenance.
Summary of the invention
The purpose of the utility model is to provide a kind of desulfurizing iron winding-up well head whole totally-enclosed air seal set, and it is rational in infrastructure, makes into the semi-enclosed sealing gland that goes up totally-enclosed; Can prevent the diffusion of flue gas; Improve Working environment, prolong the work-ing life of sealing gland ring, maintenance is convenient, safety.
The purpose of the utility model is achieved in that the whole totally-enclosed air seal set of a kind of desulfurizing iron winding-up well head; Be included in the lance tube of installing in the platform well head, twice sealing gland ring is being set on lance tube, the petticoat pipe that has dedust air duct is being set in the bottom of sealing gland ring; Axial cylindrical shell is being set on the platform well head; Lance tube is positioned on the axis of cylindrical shell, and twice sealing gland ring is fixed in the cylindrical shell, affixed closed cylinder cover plate suitable for reading on the lance tube of cylindrical shell upper end.
The aperture of the utility model sealing gland ring increases to Φ 1200mm from original Φ 1000mm, and the spray gun slagging scorification has improved up and down trafficability characteristic during rifle.With Φ 1250 * 1600 * 8mm cylindrical shell up and down two sealing glands be linked to be an integral body, remove the tracheae utilization during maintenance and change the rifle cantilever and hang direct integral body and hang out, be convenient to maintenance.The cover plate of a Φ 1400mm of correct position repair welding in spray gun upper end has made sealing gland on half open form into totally-enclosed, effectively prevents the diffusion of flue gas, thus environmental requirement when improving production.
After the utility model used, dust obviously reduced, and has purified operating environment effectively.The utility model is rational in infrastructure, makes into the semi-enclosed sealing gland that goes up totally-enclosedly, has effectively prevented the diffusion of flue gas, has improved Working environment, has prolonged the work-ing life of sealing gland ring, and maintenance is convenient, safety.
Description of drawings
To combine accompanying drawing that the utility model is done further to describe below, accompanying drawing 1 is the structural representation of the utility model.
Embodiment
The whole totally-enclosed air seal set of a kind of desulfurizing iron winding-up well head shown in accompanying drawing 1, is included in spray gun 1 pipe of installing in platform 3 well heads; On spray gun 1 pipe, twice sealing gland ring 7 is being set; In the bottom of sealing gland ring 7 petticoat pipe 6 that has dedust air duct 4 is being set, axial cylindrical shell 8 is being set on platform 3 well heads, spray gun 1 pipe is positioned on the axis of cylindrical shell 8; Twice sealing gland ring 7 is fixed in the cylindrical shell 8, affixed closed cylinder 8 cover plate 2 suitable for reading on the spray gun of cylindrical shell 8 upper ends 1 pipe.The aperture of sealing gland ring 7 is 1200mm.The diameter of cover plate 2 is 1400mm.Cylindrical shell 8 diameters are 1250mm, and height is 1600mm.Match with the molten iron in the iron ladle 5 in the lower end of spray gun 1 pipe.
