Abstract
The utility model discloses a discharge opening, which comprises a discharge pipe. A sealing device is arranged at a material inlet of the discharge pipe. The discharge opening is characterized in that the discharge pipe has a single-layer structure; and a thickening layer is arranged on the discharge pipe. The discharge pipe has the single-layer structure, the thickening layer is arranged on an abraded part, and the end part of the material inlet has an inclination angle of 5 to 60 degrees for transition, so that the water cooling facilities of the conventional discharge opening are eliminated, and the accumulation and clogging of materials at the discharge opening are effectively avoided; the discharge opening is simple in structure, and is not required to be repair-welded and overhauled within service life; and a cooling medium is not required, the discharge pipe is made from heatproof and abrasion-proof alloy steel or heatproof and abrasion-proof ceramics, the effective wall thickness of the discharge opening can be remarkably increased compared with that of the conventional discharge opening, and the discharge opening is heatproof and abrasion-proof, so that the service life of the discharge opening is prolonged.
Description
Technical field
The utility model belongs to metallurgical technology field, is specifically related to a kind of feed opening.
Background technology
Produce a large amount of high-temperature flue gas during the converter smelting oxygen blast, for the waste heat that reclaims high-temperature flue gas reduces the converter gas temperature simultaneously, for follow-up converter gas dedusting creates conditions, the converter gas outlet is provided with the flue type residual heat boiler.Need add various materials during converter smelting, so converter flue formula waste heat boiler is provided with feed opening.Existing feed opening all adopts water-cooling pattern, because the wearing and tearing of material, the feed opening life-span of water-cooling pattern is very short, and in case appearance is worn and torn, the generation water coolant leaks then converter and must blowing out carry out repair welding, otherwise converter can't be made steel.Because feed opening adopts water-cooled, need outside water cycle and treatment system, complex structure simultaneously.
Since existing feed opening complex structure, and have short problem in work-ing life, therefore need improve feed opening.
The utility model content
The purpose of the utility model is to provide a kind of externally cooled and feed opening simple in structure of not needing.
The purpose of the utility model is achieved in that a kind of feed opening, comprises that the material inlet place of tremie pipe and tremie pipe is provided with tightness system, and it is characterized in that: said tremie pipe is a single layer structure, and said tremie pipe is provided with thickening layer.
Above-mentioned thickening layer and tremie pipe are integrated.
Above-mentioned thickening layer also can be the wear-resisting steel bar of built-up welding.
Above-mentioned thickening layer is whole thickening or the thickening of local projection.
Above-mentioned integral structure is an integral casting forming.
Above-mentioned thickening layer is provided with the transition inclination angle in the material inlet end, and said transition inclination angle scope is 5～60 °.
Above-mentioned tightness system is a nitrogen gas seal equipment.
Above-mentioned tremie pipe material therefor is heat-resisting, wear-resisting alloy steel or heat-resisting, wear-resistant ceramic.
The utlity model has following beneficial effect, the utility model tremie pipe adopts single layer structure, and frayed part is provided with thickening layer and 5-60 ° of inclination angle transition of employing in the material inlet end; Save the water-cooled facility of existing feed opening, and effectively avoided the accumulation of feed opening place material to block, simple in structure; Do not need the repair welding maintenance in useful life period; And owing to do not need heat-eliminating medium, that tremie pipe adopts is heat-resisting, wear-resisting alloy steel or heat-resisting, wear-resistant ceramic, and its effective thickness can significantly increase than existing feed opening effective thickness; And heat-resisting, wear-resisting, thereby effectively prolonged work-ing life of feed opening.
