Abstract
The utility model relates to an oxygen lance for smelting, in particular to a split detachable oxygen lance, which consists of a hollow coherent oxygen lance inner core, a coherent oxygen lance middlesleeve and a water cooling protection sleeve, wherein the coherent oxygen lance middle sleeve is directly sleeved outside the hollow coherent oxygen lance inner core; the water cooling protection sleeve is sleeved outside the coherent oxygen lance middle sleeve; and a hollow channel of the coherent oxygen lance inner core is a main oxygen channel. A channel formed between the coherent oxygen lance inner core and the coherent oxygen lance middle sleeve is a gas channel, and a channel formed between the coherent oxygen lance middle sleeve and the water cooling protection sleeve is an auxiliaryoxygen channel. A cooling water channel is arranged in the water cooling protection sleeve. The utility model has the advantages that the detachment is convenient, which is convenient for maintenanceand repair; the components are interchangeable, and the consumption of spare parts is reduced, therefore the product cost is reduced.
Description
Technical field
The utility model relates to the oxygen rifle of smelting usefulness, particularly a kind of split fast disassembly type coherent oxygen lance.
Background technology
Present furnace wall coherent oxygen lance, complex structure is not easy dismounting, makes troubles to maintenance; In addition, each parts of existing oxygen rifle do not have interchangeability, and during single parts damages, whole oxygen rifle will be scrapped.
Summary of the invention
The utility model for solve the oxygen rifle be not easy the dismounting, maintenance difficult, parts do not have interchangeability deficiency, a kind of split fast disassembly type coherent oxygen lance is provided.
The utility model is realized by following measure:
Split fast disassembly type coherent oxygen lance of the present utility model; by the coherent oxygen lance inner core of hollow, be socketed in the outer coherent oxygen lance of coherent oxygen lance inner core cover and be socketed in the coherent oxygen lance outer water-cooling protective sleeve three parts of cover and form; the hollow channel of coherent oxygen lance inner core is the main oxygen passage; the passage that forms between the cover in coherent oxygen lance inner core and the coherent oxygen lance is a blast tube; the passage that forms between cover and the water-cooling protective sleeve in the coherent oxygen lance is secondary oxygen channel, is provided with cooling-water duct in the water-cooling protective sleeve.
Split fast disassembly type coherent oxygen lance of the present utility model, being connected of cover rear end is that the loose joint bolting of overlapping on the sidewall in being had the flange of U type groove and be fixed on coherent oxygen lance by the side is connected in boundling rifle inner core and the boundling rifle, the internal diameter of cover front end equates that the outside of boundling rifle inner core front end has some radially air channels in the external diameter of boundling rifle inner core front end and the boundling rifle; Cover is to have the flange of U type groove by the side to be connected with loose joint bolting on being fixed on the water-cooling protective sleeve sidewall with being connected of water-cooling protective sleeve rear end in the boundling rifle; the external diameter of cover front end equates with the internal diameter of water-cooling protective sleeve front end in the boundling rifle, and the outside of cover front end has some radially air channels in the boundling rifle.
The beneficial effects of the utility model are: the one, and cover in water-cooling protective sleeve, the coherent oxygen lance, coherent oxygen lance inner core three parts are relatively independent, and three partly by the connection of loose joint bolt, easy accessibility; When the oxygen rifle takes place to stop up, only need each parts separately just can be easy to cleaning.The 2nd, adopt special split-type design, each parts of oxygen rifle all have interchangeability, when single part is damaged, only need to change to damage parts, do not need to change whole oxygen rifle, have reduced the consumption of standby redundancy, thereby have reduced producing cost.
