Dustproof converter feeding device and application thereof

The invention provides a dustproof converter feeding device and application thereof, and relates to the technical field of converter smelting equipment. The interval between the discharging chute and the feeding pipe is isolated through the dustproof assembly, dust is prevented from overflowing, in addition, the air jet outlet is formed in the airtight layer in the dustproof assembly, air enters the air jet outlet through the air inlet pipe to be jetted, alloy powder is assisted to move towards the converter, the trend of overflowing upwards does not exist, dust overflowing is further avoided, and the service life of the converter is prolonged. And the sealing piece is used for blocking the upper part, so that all alloy powder enters the converter, the quality of molten steel is ensured, and environmental pollution caused by dust is avoided. 本发明提供一种防尘的转炉进料装置及其应用，涉及转炉冶炼设备技术领域。通过设置防尘组件隔绝下料溜管与进料管之间的间隔，防止粉尘溢出，此外，防尘组件中的气密层内有喷气出口，气体通过进气管进入喷气出口喷气，辅助合金粉料向转炉方向运动，而不具有向上溢出的趋势，进一步避免了粉尘溢出，且密封件在上方封堵，保证了合金粉料都进入转炉内，保证钢水的质量，避
