[0020] In order to make the person skilled in the art more clear and definite the technical scheme of the utility model, the utility model is described in further detail below in conjunction with the embodiment and the drawing, but the embodiment of the utility model is not limited to this.

[0021] For example, Figures 1-4As shown, the embodiment provides an air charging mechanism for a ferrosilicon alloy smelting furnace, which comprises a furnace body 1, an air charging pipe 2 connected to one side wall of the furnace body 1, a protection assembly 5 installed at the end of the air charging pipe 2, the protection assembly 5 comprising a protection cover 501, an array of air holes 502, an extension column 504, a spring 505 and a concave cavity 503, an air pressure gauge 3 installed on the air charging pipe 2, and a flow regulating valve 4 arranged on one side of the air pressure gauge 3.

[0022] The air charging pipe 2 is welded to one side wall of the furnace body 1, one end of the air charging pipe 2 is located in the furnace body 1, and the other end of the air charging pipe 2 is connected to a gas source, and the gas 1 is injected into the furnace body 1 through the air charging pipe 2.

[0023] The concave cavity 503 is formed in the end of the air charging pipe 2, the fixed part of the extension column 504 is welded to the concave cavity 503, and the spring 505 is welded to the outer side wall of the extension column 504, so that the protection cover 501 has a certain movement performance in combination with the extension column 504 and the spring 505.

[0024] The protection cover 501 is welded to the movable end of the extension column 504, the protection cover 501 is inserted into the air charging pipe 2, and the air holes 502 are formed in the air charging pipe 2. During the air charging process, the impact force of the gas 1 drives the protection cover 501 to move, so that the protection cover 501 is separated from the air charging pipe 2 and the extension column 504 and the spring 505 are stretched. At this time, the gas 1 enters the furnace body 1 through the air holes 502. When the air charging is completed, the protection cover 501 is reset under the action of the elastic force of the extension column 504 and the spring 505 as the impact force disappears, so that the air charging hole is located in the air charging pipe 2. This can avoid the air charging hole being always exposed and blocked by impurities, avoid affecting the subsequent air charging, ensure the air charging effect and efficiency.
