[0008] As a further improvement of the present invention, a nitrogen valve is provided on the first air inlet pipe.
[0009] As a further improvement of the present invention, the diverter pipe is in an arc shape.
[0010] As a further improvement of the present invention, three second diversion ports are provided, and the second air inlet pipes connected to the three second diversion ports and the first air inlet pipes are evenly arranged around the circumference of the ash bin.
[0011] As a further improvement of the utility model, it also includes a nitrogen generating device, the output end of the nitrogen generating device is connected to a nitrogen main pipe, and the output end of the nitrogen main pipe is connected to the input end of the first intake pipe.
[0012] An ironmaking furnace comprises the ash bin auxiliary ash unloading device as described in any one of the above items.
[0013] The beneficial effects of the utility model are as follows: the utility model has a simple structure, is easy to use, can realize fast ash unloading, and when the ash bin is blocked during ash discharge, the nitrogen valve is opened to pressurize the ash bin, which can effectively solve the ash bin discharge problem, eliminate the safety hazards and environmental hazards during ash unloading, and save labor intensity; it solves the problem in the prior art that the bag ash in the elevated ash bin is highly sticky, and the ash is often blocked on the upper part of the valve during ash discharge and cannot be released, requiring the operator to dismantle the feeder and open the valve to clear it with a steel chisel, resulting in a large amount of gas and dust leakage, posing a major safety hazard and affecting the environment.
