Description

Technical Field

[0001] This utility model relates to the field of aluminum production and processing technology, and in particular to a slag-blocking device for an electrolytic aluminum ladle used in aluminum casting and rolling. Background Technology

[0002] Aluminum and its alloys are an indispensable part of modern industrial manufacturing. Currently, molten aluminum produced by electrolysis is usually temporarily stored in an electrolytic aluminum ladle. Over time, the molten aluminum stored in the ladle will clump together. When the molten aluminum is discharged from the ladle, small lumpy slag and electrolyte impurities will be generated. Existing equipment is not very effective at removing these impurities, and it is difficult to clean and maintain the slag removal device.

[0003] When the high-temperature molten aluminum is poured directly out of the aluminum ladle, splashing occurs, which not only affects the drainage efficiency but also easily injures operators, posing a certain safety hazard. In addition, electrolytic aluminum production also produces harmful gases, causing environmental pollution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a slag-blocking device for an electrolytic aluminum ladle used in aluminum casting and rolling.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a slag-blocking device for an electrolytic aluminum ladle used in aluminum casting and rolling, comprising a slag-blocking cabinet, a feed inlet on one side of the top of the slag-blocking cabinet, a threaded connecting ring on the top of the feed inlet, threaded rings evenly distributed on the inner wall of the threaded connecting ring, a dust-covering cover on the top of the threaded connecting ring, an exhaust port on the other side of the top of the slag-blocking cabinet, a sealing cover on the top of the exhaust port, a pull-out groove on the front of the slag-blocking cabinet, a sealing ring wrapped around the outside of the pull-out groove, a temporary storage rack on one side of the slag-blocking cabinet, a liquid storage tank on one side of the bottom of the slag-blocking cabinet, a waste slag tank on the other side of the bottom of the slag-blocking cabinet, a slag cleaning port at the bottom of the waste slag tank, a liquid delivery pipe at the bottom of the liquid storage tank, and an overflow valve passing through the inside of the liquid delivery pipe.

[0006] Preferably, the slag retainer is provided with an inspection port on the other side, and the inspection port is hinged to the slag retainer.

[0007] Preferably, the slag-blocking cabinet has a screen plate that runs through the interior, corresponding to the position of the pull-out groove, and the screen plate is movably connected to the pull-out groove.

[0008] Preferably, the infusion tube has a baffle plate on the side away from the overflow valve, and the baffle plate is movably connected to the bottom of the waste residue tank. The infusion tube has a spherical groove corresponding to the position of the baffle plate.

[0009] Preferably, the feed inlet is provided with a screw rod inside, and the screw rod is movably connected to the feed inlet.

[0010] Preferably, the bottom of the slag barrier is connected to four support legs at each of the four corners, the support legs are wrapped with shock-absorbing components, and the bottom of the support legs is provided with a fixed support.

[0011] Preferably, the exhaust port includes a carbon dioxide filter plate, a hydrogen fluoride filter plate, and an activated carbon filter plate. The carbon dioxide filter plate is located near the top of the exhaust port, the activated carbon filter plate is located near the bottom of the exhaust port, and the hydrogen fluoride filter plate is located between the carbon dioxide filter plate and the activated carbon filter plate.

[0012] Beneficial effects

[0013] In this invention, a sieve plate, a spherical groove, and a slag-blocking plate are used. The sieve plate can separate lumpy slag and electrolyte impurities from the electrolytic aluminum liquid and separate the aluminum liquid from the waste residue, allowing the aluminum liquid to enter the storage tank and the waste residue to enter the waste residue tank. The spherical groove can reduce the flow rate of the electrolytic aluminum liquid, making it easier for the slag-blocking plate to intercept the floating slag on the aluminum liquid. Through the above design, the screening efficiency is improved, the purity of the electrolytic aluminum liquid is guaranteed, and energy consumption and production costs are reduced.

[0014] In this invention, a threaded connecting ring is installed at the top of the feed inlet, and a spiral rod is installed inside. The spiral rod can effectively prevent splashing when pouring electrolytic aluminum liquid, while the threaded connecting ring can conveniently and quickly connect the electrolytic aluminum water tank and the slag-blocking cabinet. This slag-blocking device has a simple structure, which can greatly reduce the installation time for operators in high-temperature environments, improve work efficiency, and reduce safety hazards. In addition, an exhaust port is provided at the top of the slag-blocking cabinet, and the exhaust port is equipped with multiple layers of filter plates to prevent harmful gases from polluting the air. This not only prevents operators from inhaling harmful gases and causing harm to their health, but also protects air resources. Attached Figure Description
