The utility model solves the technical scheme that its technical problem adopts: a kind of outer degasifying device of stove with self-cleaning function, described device comprises: shell, be located at aluminium liquid gas removal channels in described shell and through the some argon gas pipelines in described aluminium liquid gas removal channels, each argon gas pipeline comprises argon gas producer and the argon gas nozzle that is positioned at its two ends, described argon gas nozzle is positioned at the bottom of described aluminium liquid gas removal channels, each argon gas pipeline is also connected with a steam flushing pipeline, described steam flushing pipeline is located at the relative one end of described argon gas nozzle, between described steam flushing pipeline and described argon gas pipeline, be provided with switch-valve.
Further, this device is provided with three or three above described argon gas pipelines, and described argon gas pipeline is connected in same argon gas producer, and the interval between each argon gas pipeline equates.
Further, each argon gas pipeline is connected with respectively a steam flushing pipeline and a switch-valve.
Further, aluminium liquid gas removal channels comprises opening for feed and discharge port, and the position of described opening for feed and discharge port is higher than the position of described nozzle.
Further, the diameter of described aluminium liquid gas removal channels is between between 100mm to 200mm.
Further, the diameter of described argon gas pipeline is between between 30mm to 60mm.
Further, the distance between two argon gas nozzles is between between 5mm to 8mm.
Further, described argon gas nozzle is swivel nozzle.
The beneficial effects of the utility model are, by regularly opening steam flushing pipeline, utilize high pressure steam automatically to clean argon gas nozzle, avoid it to occur latch up phenomenon, guarantee the degassing effect of the outer degasifying device of stove, and cost is lower.
