However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an argon blowing conveying device for a refining furnace, comprising a conveying mechanism 1, and a filter mechanism 2 is movably sleeved on the outer wall of the conveying mechanism 1;

[0025] The conveying mechanism 1 includes an operating panel 101, a column 102 is fixedly installed on the top of the operating panel 101, a plurality of support blocks 103 are fixedly installed on the outer wall of the column 102, two air connection pipes 104 are fixedly installed between the tops of the plurality of support blocks 103, a gas delivery pipe 105 is fixedly installed on one side of the outer wall of the two air connection pipes 104, a meter head 106 is fixedly installed on the top of the two air connection pipes 104, a main control valve 107 is fixedly installed on one side of the outer wall of the two air connection pipes 104, and the two air connection pipes 104 are fixedly installed on the outer wall of the two air connection pipes 104. A straight pipe 108 is fixedly installed at the bottom, and the outer walls of the two straight pipes 108 are connected to the inside of the operating panel 101; two bypass pipes 109 are fixedly installed at the bottom of the two air connecting pipes 104, and the outer walls of the two bypass pipes 109 are connected to the inside of the operating panel 101; a secondary control valve 110 is fixedly installed on one side of the outer wall of the four bypass pipes 109; a permeable brick 111 is fixedly installed on the top of the operating panel 101, and a ladle 112 is fixedly installed on the top of the permeable brick 111.

[0026] The effect achieved by the entire embodiment 1 is that, first, after adding materials during the smelting process, in order to facilitate the chemical reaction between steel and slag, a large flow of argon gas is required for stirring. At this time, by controlling the two main control valves 107, the argon gas passing through the gas pipe 105 and the gas connecting pipe 104 passes through the straight pipe 108 and leads to the air-permeable brick 111 fixedly installed at the bottom of the ladle 112, so that a large flow of argon gas is used for stirring the molten steel, which is conducive to the chemical reaction between steel and slag. Then, in the later stage of smelting, a small flow of argon gas passing through the gas pipe 105 and the gas connecting pipe 104 is passed through the four secondary control valves 110, and the bottom of the ladle 112 is soft-blown along the four bypass pipes 109, thereby promoting the floating of molten steel inclusions. Therefore, the straight pipe 108 controls the stirring of large flow of argon gas, and the bypass pipe 109 controls the soft blowing of small flow of argon gas, which is convenient for production workers to operate, improves the argon blowing stirring and soft blowing effects of molten steel, and improves work efficiency.

[0027] Embodiment 2, as Figure 2-Figure 4 As shown, the filtering mechanism 2 includes an air storage box 201, and two limit grooves 202 are provided on the inner wall of the air storage box 201, and limit blocks 203 are movably inserted into the inner walls of the two limit grooves 202, and handle holes 204 are provided on one side of the outer walls of the two limit blocks 203, and a filter screen 205 is fixedly installed between the opposite sides of the outer walls of the two limit blocks 203, and an activated carbon layer 206 is placed on the top of the filter screen 205. A cover plate 207 is placed on the air storage box 201, and the cover plate 207 is movably sleeved between the outer walls of the two air pipes 105, and the input ends of the two air pipes 105 are connected to the interior of the air storage box 201.

[0028] The effect achieved by the entire embodiment 2 is that when argon is transported, it first passes through the filter 205 and the activated carbon layer 206. The activated carbon itself has good adsorption capacity, so that organic pollutants, odorous substances, etc. in the gas can be removed, and impurities are left on the filter 205. Because the filter 205 is movably inserted into the two limit grooves 202 through the limit blocks 203 installed on both sides, and then through the two handle holes 204, it is convenient for the staff to take out the filter 205 and the activated carbon layer 206 for replacement or cleaning, thereby improving the purity of the argon, thereby further improving the effect of stirring and soft blowing of the molten steel by bottom blowing argon.

[0029] Working principle: First, when transporting argon, the argon passes through the filter 205 and the activated carbon layer 206. The impurities in the filter 205 are effectively removed by the adsorption capacity of the activated carbon layer 206, and are left on the filter 205, thereby improving the purity of the transported argon. Then, the two limit blocks 203 and the filter 205 are taken out and replaced or cleaned through the handle hole 204. After adding materials during the smelting process, a large flow of argon is passed through the gas transmission pipe 105 and the gas connection pipe 104 through the main control valve 107, and enters the inside of the ladle 112 along the straight pipe 108 and the air-permeable brick 111, thereby promoting A large flow of argon is used for stirring the molten steel, and then in the later stage of smelting, a small flow of argon is allowed to pass through the gas pipe 105, the gas connecting pipe 104 and along the four bypass pipes 109 for soft blowing through four secondary control valves 110. In general, the two straight pipes 108 control the large flow of argon stirring, and the four bypass pipes 109 control the small flow of argon soft blowing, so as to achieve the optimization and transformation of the bottom blowing argon control valve group. Each argon blowing pipeline is composed of a straight pipe 108 and a bypass pipe 109, which is convenient for production workers to operate, improves the argon blowing stirring and soft blowing effects of molten steel, and improves work efficiency.
