Description

Technical Field

[0001] The utility model relates to the technical field of an impurity processing device in a smelting furnace, in particular to an impurity processing device in a smelting furnace. Background Art

[0002] A melting furnace is a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then melts them into the required alloys through operations such as slagging and refining. The melting furnace generates high-density magnetic lines in the induction coil and cuts the metal materials contained in the induction coil, generating large eddy currents in the metal materials. This eddy current also has some properties of medium-frequency currents, that is, the free electrons of the metal itself flow in the metal body with resistance to generate heat. However, after the melting furnace is used, slag is easily adhered to the inner wall of the melting furnace. The slag adhered to the inner wall of the melting furnace is not easy to clean. When the next melting is carried out, the slag adhered to the melting furnace reduces the purity of the molten aluminum liquid in the melting furnace, thereby reducing the quality of the castings.

[0003] An impurity treatment device for a smelting furnace disclosed in the Chinese utility model patent application publication specification CN218627811U solves the problem that the slag on the inner wall of the smelting furnace is difficult to clean. However, the impurity treatment device for the smelting furnace still has the following disadvantages: First, because the sizes of smelting furnaces are not uniform, it is necessary to find a corresponding impurity treatment device when cleaning the impurities inside the smelting furnace, and the scope of use is relatively limited, which is not conducive to wide use; Second, when cleaning the impurities inside the smelting furnace, since the impurities are relatively dispersed, they cannot be completely extracted by the exhaust fan, and part of the slag will fall to the bottom of the smelting furnace, reducing the purity of the metal to be smelted next time, affecting the quality of the product.

[0028] During use, because the sizes of smelting furnaces are not uniform, it is necessary to find a corresponding impurity processing device when cleaning impurities inside the smelting furnace. The scope of use is relatively limited, which is not conducive to widespread use. Therefore, there is an impurity processing device in a smelting furnace.

The inner bottom of the movable rod 21 is rounded. The end of the movable rod 21 away from the rotating rod 20 is fixedly connected to a light rod. Blocks 22 are rotatably connected to the two sides of the light rod. The bottom of the block 22 is fixedly connected to a fixed rod 23. The fixed rod 23 is fan-shaped.

The bottom of the rubber plate 24 is fixedly connected to a bottom plate 25. The bottom plate 25 is cylindrical, and the bottom of the bottom plate 25 is tightly attached to the inner bottom wall of the furnace body 1.

[0031] During use, when the impurities inside the smelting furnace are cleaned, since the impurities are relatively dispersed and cannot be completely extracted by the exhaust fan, a part of the slag will fall to the bottom of the smelting furnace, reducing the purity of the metal to be smelted next time and affecting the quality of the product. Therefore, there is an impurity processing device in the smelting furnace. When the impurity processing device is placed inside the furnace body 1, after the bottom plate 25 is placed on the bottom wall of the furnace body 1, the telescopic end of the third electric telescopic rod 17 extends out, driving the chuck 18 to move downward, and then the two ends of the movable rod 21 begin to rotate accordingly, so that the fixed rod 23 rotates downward, so that the rubber sheet 24 can extend outward. By setting the rubber sheet 24 as a high-cis-butadiene rubber, the rubber sheet 24 can have strong stretchability and elasticity, avoiding the rubber sheet 24 from breaking before it contacts the inner wall of the furnace body 1. When the edge of the rubber sheet 24 is close to the inner wall of the furnace body 1 , the telescopic end of the third electric telescopic rod 17 stops extending, and starts to clean the impurities inside the smelting furnace. After the impurities inside the smelting furnace are cleaned, the telescopic end of the third electric telescopic rod 17 is retracted, so that the rubber plate 24 and the fixed rod 23 drive the fallen impurities to rotate and shrink upward, so that all the impurities can be taken out of the smelting furnace. The telescopic end of the third electric telescopic rod 17 is fixedly connected with the chuck 18, so that the impurity processing device in the smelting furnace has the effect of preventing slag from falling on the bottom of the smelting furnace, ensuring the purity of the next smelting metal, and not affecting the quality of the product. Through the coordinated arrangement of the rubber plate 24 and the third electric telescopic rod 17, the rubber plate 24 can be made to close to the inner wall of the smelting furnace body 1 during use, thereby preventing slag from falling on the bottom of the smelting furnace, achieving the purpose of ensuring the purity of the next smelting metal and not affecting the quality of the product.
