Description

Technical Field

[0001] This utility model relates to the technical field of slag removal equipment, specifically an automatic slag removal device for molten iron poured at anodes. Background Technology

[0002] The main function of the electrolytic aluminum anode assembly line is to provide assembled anodes for aluminum electrolysis production. The anode assembly line consists of a series of specialized equipment, where guide rod assemblies and prebaked anode carbon blocks are combined to become one of the raw materials for electrolysis production.

[0003] The anode casting process is the most important process in the anode assembly production line. Modern anode assembly production lines generally use medium-frequency furnaces to melt and cast molten iron. The raw materials used include cast iron, recycled ferrophosphorus rings, ferrophosphorus, ferromanganese, and ferrosilicon. The materials are melted in a medium-frequency electric furnace according to the proportion to form liquid molten iron that meets the process requirements. The guide rod assembly and prebaked anode carbon blocks are combined by a special casting equipment. The molten iron is poured into the gap between the steel claw of the guide rod assembly and the pre-reserved blind hole at the top of the prebaked anode. After the molten iron cools and solidifies, the guide rod assembly and the prebaked anode carbon block are combined into a solid whole.

[0004] During the smelting of molten iron in a medium-frequency electric furnace, a large amount of slag is generated, which floats and solidifies on the surface of the molten iron. If this slag is not removed, it will affect the casting performance of the molten iron. Currently, the slag removal operation is carried out in a relatively traditional way, in which slag removers wear protective gear and stand close to the furnace opening, using long iron forks to pick up slag from the slag box outside the furnace. Iron slag and molten iron splash everywhere, which is very unsafe. Slag removers are directly exposed to the high temperature of molten iron, and there are many hazards such as high temperature, burns, and smoke.

[0005] During the smelting of molten iron in a medium-frequency electric furnace, the temperature inside the furnace can reach 1500 degrees Celsius, and even in summer, the temperature around the furnace opening can reach several hundred degrees Celsius, making the working environment extremely harsh. The slag has strong adhesive properties, and when it clumps together, it becomes very heavy, requiring extensive manual labor to remove completely. Furthermore, a significant amount of high-quality molten iron adheres to the slag during removal, resulting in substantial waste of raw materials. The traditional slag removal methods not only pose significant personal safety hazards but are also extremely labor-intensive, inefficient, and result in substantial molten iron loss.

[0006] The slag removal tool for molten iron in medium frequency furnaces is made of carbon steel. Before use, a handle of a certain length needs to be welded. The manufacturing process is complicated and the material consumption is relatively large. In order to ensure the convenience of workers, the overall weight and length of the tool must be limited to a certain range. The heat resistance of carbon steel slag removal tools is limited, the service life of slag removal tools is very short, the consumption is high, and a lot of material costs are required.

[0007] To address the safety hazards of slag removal operations, reduce labor intensity, and improve efficiency, it is essential to find an intelligent, mechanized, and automated method to replace manual labor, thereby freeing slag removers from heavy physical labor and promoting the advancement of equipment levels in anode assembly production lines. Utility Model Content

[0008] The purpose of this utility model is to provide an automatic slag removal device for molten iron casting in anodes that has a reasonable structural design, is easy to operate, has low processing and manufacturing costs, is safer and more reliable to operate, saves time and effort, can set parameters according to the on-site working conditions of slag removal, realizes automated slag removal operation, and fully ensures the personal safety of on-site personnel.

[0009] This utility model discloses an automatic slag removal device for molten iron in anode casting, including a furnace surface, an electric furnace installed on the furnace surface, a slag removal robot installed on the furnace surface, a control box installed on the bottom surface of the slag removal robot, a mounting base of the slag removal robot installed on the surface of the control box, a fixing rod connected to the surface of the mounting base, an operating rod connected to one end of the fixing rod, an operating head fixedly connected to the end of the operating rod, a fixing plate fixedly connected to the bottom surface of the operating head, and slag removal grabs hinged to the two side walls of the fixing plate respectively.

[0010] A slag box is provided on the furnace surface.

[0011] An ash-collecting bucket is installed on the furnace surface.

[0012] The slag-removing robot is mounted on a base attached to the control box. Various parameters for slag removal can be set through the control box. Once set, the robot performs slag removal operations according to these parameters. A fixed rod drives an operating rod that extends into the electric furnace. A slag-removing grab, located at the end, extends into the furnace and removes slag. After inserting into the slag, the grab closes, leaving the slag inside. Once closed, the grab is pulled out of the furnace and moved along a predetermined path. The slag grab bucket opens above the slag box, dumping the slag into the box and completing one slag removal cycle. The slag box can be used to store slag; once a certain amount is stored, the slag in the box can be recycled and processed. The ash-adhesive bucket is used to store cooled ash. When the slag grab bucket is in operation, it will heat up, so it can be inserted into the ash-adhesive bucket to cool it down, ensuring the normal operation of the slag grab bucket. The operation is more convenient, easier to assemble, safe and reliable, saves time and manpower, and ensures the safety of operators.

[0013] Safety railings are installed on the sides of the slag box and ash-adhesive bucket.

[0014] The safety railings installed protect the slag bins and ash-contaminated buckets, preventing them from tipping over or overflowing, and avoiding overheating that could injure operators, thus ensuring a safe working environment for them.

[0015] A fixing seat is fixedly installed along the edge of the furnace side wall. Fixing baffles are fixedly installed on both sides of the fixing seat. A connecting plate is bolted to the outer side wall of the fixing baffle. A dust removal hood is fixedly installed on the side wall of the connecting plate. A dust suction port is provided on the bottom surface of the dust removal hood.

[0016] The dust hood is fixedly installed on the side wall of the furnace using a mounting bracket. It can be positioned above the electric furnace and its angle can be adjusted using bolts. The angle can be adjusted arbitrarily according to the requirements of the site conditions, making it highly adaptable and safe and reliable to operate. The dust suction port can absorb the dust generated inside the electric furnace, effectively reducing the impact of dust on the health of operators and ensuring the smooth operation of slag removal.

[0017] An emergency pit is provided at the bottom of the furnace surface, and the emergency pit is located on the side wall of the electric furnace.

[0018] The emergency pit is designed to handle leaks of molten iron from the electric furnace. In the event of a leak, the molten iron can be stored in the emergency pit to prevent losses caused by the leak.

[0019] Multiple safety light curtains are evenly arranged along one side edge of the furnace surface.

[0020] The safety light curtain is located on one side of the furnace surface. It forms a light curtain by emitting infrared beams. When an object or person enters the beam area of ​​the safety light curtain, the system will immediately detect it and take safety measures, such as stopping the mechanical movement or triggering an alarm. The function of the safety light curtain is to ensure that when personnel or objects enter the dangerous area during the operation of machinery or industrial equipment, the mechanical movement can be stopped or slowed down in time, thereby preventing accidental injury and accidents.

[0021] The beneficial effects of this utility model are:

[0022] 1) The slag-removing robot is mounted on a base attached to the control box. Various parameters for slag removal can be set via the control box. Once set, the robot performs slag removal according to these parameters. A fixed rod drives an operating rod that extends into the electric furnace. A slag-removing grab located at the end of the robot extends into the furnace. The grab then removes slag, closing after insertion and leaving the slag inside. After closing, the grab is pulled out of the furnace and follows a predetermined path. Moved above the slag box, the slag grab opens to pour the slag into the slag box, completing one slag removal cycle. The slag box can be used to store slag. After a certain amount of slag is stored, the slag in the slag box can be recycled and processed. The ash-adhesive bucket is used to store cooled ash. When the slag grab is operated, it will heat up, so it can be inserted into the ash-adhesive bucket to cool down the slag grab, ensuring the normal operation of the slag grab. The operation is more convenient, easier to assemble, safe and reliable, saves time and manpower, and ensures the safety of operators.

[0023] 2) The safety railings installed can protect the slag box and ash bucket, preventing them from being tipped over or overflowing, or from being exposed to excessively high temperatures, thus ensuring the safety of the operators' working environment.

[0024] 3) The dust hood is fixedly installed on the side wall edge of the furnace surface using a mounting bracket. The dust hood can be positioned above the electric furnace. The angle of the dust hood can be adjusted using the bolts. The required angle can be adjusted arbitrarily according to the requirements of the site conditions. It is highly adaptable, safe and reliable to operate. The dust suction port can absorb the dust generated inside the electric furnace, effectively reducing the impact of dust on the health of operators and ensuring the smooth operation of slag removal.

[0025] 4) An emergency pit is set up to deal with the leakage accident of molten iron in the electric furnace. Once the molten iron in the electric furnace leaks, the flowing molten iron can be stored in the emergency pit to prevent the loss caused by the leakage.

[0026] 5) This automatic slag removal device has a reasonable structural design, is easy to operate, has low processing and manufacturing costs, and is safer and more reliable in operation. It saves time and labor. Parameters can be set according to the on-site working conditions to achieve automated slag removal operation, fully ensuring the personal safety of on-site personnel. It replaces manual slag removal, improves the automation level of the anode assembly production line, and transforms the original manual workshop-style operation mode into an intelligent fully automatic operation mode. It reduces the residence time of molten iron in the furnace caused by slag removal, and reduces power consumption. Personnel only need to stay away from the high-temperature furnace mouth and operate remotely, avoiding the risk of high temperature and burns caused by close-range operation. It reduces the labor intensity of slag removal for operators, reduces the time operators are exposed to high temperature and dust, and protects the occupational health of operators.
