Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnaces, in particular to a smelting furnace slag cleaning device. Background Art

[0002] A smelting furnace refers to a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then melts them into the required alloy through operations such as slagging and refining. After the use of the smelting furnace, some residue will adhere to the inner wall of the smelting furnace. At this time, it is necessary to pour in a refining agent to reduce the adhesion of the residue, and then use a shovel or iron rod to scrape off the slag.

[0003] The publication number in the existing public technology is: CN215176973U. A slag cleaning device for an oxygen-enriched smelting furnace includes a base, a cleaning bracket and a recovery bracket. A screw is installed in the base through a bearing, and a corresponding wire block is arranged on the periphery of the screw. A slide is arranged on the top of the base, and the slide is connected to the wire block through a reserved opening. A cleaning bracket is arranged on the top of the slide. An annular slide groove is provided on the surface of the cleaning bracket, and a slider is slidably connected in the annular slide groove. A brush is arranged on one side of the slider on the periphery of the annular slide groove. The utility model provides a slag cleaning device for an oxygen-enriched smelting furnace, which has a simple and compact structure, is easy and reliable to operate, and can improve the cleaning efficiency, and is suitable for being widely promoted and used.

[0004] However, the above patent still has certain disadvantages when used: it only performs slag removal operations on the inner wall of the smelting furnace, while the slag at the bottom of the smelting furnace is not effectively treated, and secondary treatment operations are required later. The slag removal range is relatively limited, which affects the overall slag removal effect. In addition, since the distribution and thickness of the filter slag are different, and the structural dimensions of the slag removal are relatively fixed, when the slag thickness is large, the slag removal structure directly collides with the slag, which will not only cause damage to the slag removal structure, but also cause damage to the inner wall of the smelting furnace. When the slag thickness is small, the slag removal structure may not be able to make effective contact with the slag, resulting in the inability to effectively remove it, affecting the use effect of the device, and the overall practicality is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model provides a smelting furnace slag cleaning device, which has the following beneficial effects:

[0020] (1) The utility model adopts a first spring and a second spring. When the driving shaft rotates, due to the influence of centrifugal force, the second spring and the second telescopic rod can extend outward, thereby moving the lateral slag removal plate outward, so that the lateral slag removal plate can be fitted to the inner wall of the smelting furnace. Since the extension amount of the lateral slag removal plate can be controlled, it can be suitable for use in smelting furnaces of different diameters, thereby expanding the application range of the device. Moreover, after the lateral slag removal plate moves, due to the different thickness of the slag on the inner wall of the smelting furnace, the brush extended by the first spring and the first telescopic rod can respectively abut against the surface of the slag with different thicknesses, thereby avoiding damage caused by the fixed slag removal structure. Then, through high-speed rotation, the brush can gradually grind and remove the abutting slag surface, thereby realizing slow and progressive slag removal operations. Not only can the overall slag removal effect be improved, but also the damage to the furnace wall of the smelting furnace can be reduced, thereby having the advantage of less damage to the furnace wall.

[0021] (2) The utility model adopts a lateral slag removal plate and a bottom slag removal ring. In actual use, the slag removal operation on the inner wall of the smelting furnace can be realized by rotating the lateral slag removal plate. Then, while the slag is being removed from the inner wall, the bottom of the smelting furnace can also be subjected to corresponding slag removal treatment by rotating the bottom slag removal ring. The device can simultaneously perform slag removal operations on the furnace wall and the furnace bottom of the smelting furnace through the lateral slag removal plate and the bottom slag removal ring, thereby expanding the slag removal range of the device and making the overall slag removal effect better. There is no need for subsequent secondary slag removal operations, which reduces the labor intensity of personnel. Moreover, during slag removal, the two can be driven by the first spring and the first telescopic rod to abut against each other and change accordingly with the different slag thicknesses, so as to better fit the slag surface that needs to be processed, thereby realizing slow and multiple step-by-step slag removal operations on the slag surface. This can not only improve the overall slag removal effect, but also reduce the damage to the furnace wall of the smelting furnace. It has the advantages of a wide slag removal range and a good slag removal effect. BRIEF DESCRIPTION OF THE DRAWINGS
