[0002] The deslagging device of steelmaking furnace is a device used to remove the slag in the furnace during the steelmaking process. In the steelmaking process, the slag is formed by impurities and oxides in the charge. If it is not removed in time, it will have an adverse effect on the quality of molten steel and production efficiency. Therefore, deslagging is a very important link in the steelmaking process, among which mechanical deslagging: mechanical devices such as deslagging pots and centrifuges are used to separate the slag in the furnace from the molten steel. The slag is usually separated and discharged by rotation or centrifugal force.

[0003] A mobile steelmaking furnace slag removal device is disclosed in a utility model patent with patent authorization announcement number CN208195640U, including a slag remover, a feed port is provided on the top of the slag remover, an exhaust fan is provided on one side of the feed port relative to the top of the slag remover, a dust collecting hood is provided in the middle of the exhaust fan by snap-fitting, an annular groove of an integrated structure is provided on the surface of one end of the dust collecting hood, and a clamping ring matched with the annular groove is provided in the middle of the exhaust fan, and a discharge port is provided on the side of the slag remover; by arranging an exhaust fan at the top of the slag remover, the dust inside the slag remover is discharged by utilizing the effect of the exhaust fan, so as to avoid dust scattering and corrosion of the internal parts of the slag remover, and facilitate users to clean the slag remover, thereby reducing the labor intensity of users; by arranging baffles, filters and water collecting troughs on both sides of the conveyor belt, utilizing the collection effect of the water collecting trough, it is avoided that the water after use is not collected in time, causing a certain degree of corrosion to the internal parts of the slag remover.

[0004] However, the existing steelmaking furnace slag removal device also has certain shortcomings. First, the existing steelmaking furnace slag removal device mostly uses bolts to install the exhaust fan. Since the use of bolts requires professional assembly tools, it is obviously inconvenient for operators to use;

[0005] Secondly, the existing steelmaking furnace slag removal devices mostly simply use a discharge pipe to discharge the steel slag. Due to the influence of factors such as the diameter of the discharge pipe itself, the discharge pipe is easily blocked. Summary of the invention
