Description

Technical Field

[0001] This utility model belongs to the field of aluminum liquid production technology, and in particular relates to a leak-proof sealing device for aluminum liquid in a filter box. Background Technology

[0002] In the aluminum casting process, the filter box is a crucial piece of equipment for ensuring the quality of the molten aluminum. Its function is to filter impurities from the molten aluminum to improve the quality of the castings. However, in actual production, the sealing and leakage prevention of the filter box has always been a difficult problem for the industry. Molten aluminum is characterized by high temperature and high fluidity. Once a leak occurs, it not only wastes the molten aluminum and increases production costs, but also poses a serious threat to the safety of production equipment and personnel. Moreover, leaked molten aluminum will solidify on equipment and in the work area, making cleanup difficult and affecting production efficiency.

[0003] To address this issue, existing technologies typically employ conical plugs to seal or open the aluminum outlet. These existing plugging devices are fixed in one piece, attached to the filter box or chute, making easy disassembly and reassembly difficult. Secondly, since aluminum is frequently discharged from the filter box during its production cycle, using plugs results in the device being covered by molten aluminum, which then cools and coats the device. This inevitably leads to corrosion of the plug by the high-temperature molten aluminum, or the aluminum solidifying and encasing the plugging device. Therefore, regular cleaning of the plugging device, as well as the aluminum outlet and chute, is required. The existing fixed plugging devices, due to their inconvenient disassembly and reassembly, hinder the proper execution of these cleaning tasks and also impede plug replacement. Utility Model Content
