[0033] The automatic dust discharging device for oxygen-enriched side blowing furnace disclosed in the embodiment is connected with an oxygen-enriched side blowing furnace (not shown in the figure) and a dust extraction fan (not shown in the figure) at the smoke inlet 11 and the smoke outlet 12 respectively before use, the dust extraction fan is a common centrifugal fan, the first telescopic rod 16, the second telescopic rod 32 and the third telescopic rod 46 are sequentially turned on at the controller 5, so that the three telescopic rods are telescoped according to their respective frequencies, and the original material receiving device is connected with the dust discharging pipe 14.

[0034] In use, the flue gas generated by the oxygen-enriched side-blown furnace is sucked into the dust collector housing 1 from the smoke inlet 11 by the dust extraction fan, and is extracted from the smoke outlet 12, thereby completing the dust extraction process. When the flue gas enters the dust collector housing 1, it first contacts the first baffle, and the copper powder in the flue gas adheres to the side of the first dust baffle 21 away from the second dust baffle 22. When a certain amount of copper powder adheres, it falls into the dust hopper 13 under the action of gravity. Under the action of the dust extraction fan, the flue gas passes under the first dust baffle 21 and then contacts the second dust baffle 22 in turn, and the copper powder adheres to the second dust baffle 22, thereby ensuring the adsorption effect of the copper powder in the flue gas. The flue gas passing through the second baffle is discharged from the dust collector housing 1 through the smoke outlet 12.

When the elastic ring 43 contacts the side wall of the dust collector housing 1, the second scraper 41 is pushed to the side of the first dust baffle 21, and the third telescopic rod 46 is closed. The first telescopic rod 16 can drive the blocking plate 15 to move in the dust discharge pipe 14, and adjust the depth of the blocking plate 15 inserted into the dust discharge pipe 14. When the blocking plate 15 is pulled out of the dust discharge pipe 14, the copper powder on the blocking plate 15 is scraped off through the lower end of the dust discharge pipe 14 and discharged into the original material receiving device. When the first telescopic rod 16 is elongated, the blocking of the dust discharge pipe 14 by the blocking plate 15 is restored, so that the copper powder can be discharged after a sufficient amount of copper powder is collected in the dust hopper 13.

[0035] The dust collector housing 1, the controller 5, the smoke inlet 11, the smoke outlet 12, the dust hopper 13, the blocking plate 15, the first telescopic rod 16, the bracket 17, the first dust baffle 21, the second telescopic rod 32, the telescopic protective cover 33, the support rod 42, the elastic ring 43 and the third telescopic rod 46 in the automatic dust discharging device for the oxygen-enriched side-blown furnace are all general standard parts or parts known to those skilled in the art, and the structure and principle thereof can be known by those skilled in the art through technical manuals or through conventional experimental methods.
