Description

Technical Field

[0001] This utility model relates to the field of lifting vehicle technology, specifically a structure for a feeding lifting vehicle for a centralized aluminum molten metal furnace. Background Technology

[0002] A centralized aluminum melting furnace is a piece of equipment used in the aluminum alloy casting process. Its main function is to melt aluminum metal and maintain it at a suitable liquid temperature for subsequent casting or casting production. It plays a vital role in the aluminum processing industry, especially in aluminum alloy casting, aluminum ingot production, and aluminum profile production. The main working principle of a centralized aluminum melting furnace is to heat aluminum metal from a solid state to a liquid state and maintain it in a stable liquid state. Common heating methods include:

[0003] Electric heating: Aluminum metal is heated to its melting temperature by electric heating elements (such as resistance wires or electric furnace tubes), usually controlled above 660°C.

[0004] Gas heating: Heating is done using natural gas or other fuels, and is suitable for large furnaces.

[0005] Oil heating: Using oil to heat aluminum metal, commonly found in smaller furnaces.

[0006] During the aluminum melting process, the furnace needs to have a good temperature control system to ensure the stability of the aluminum liquid temperature and prevent the aluminum liquid from oxidizing or overheating.

[0007] The aluminum molten metal central melting furnace is designed for efficient melting of aluminum metal, and can quickly heat solid aluminum metal to a liquid state.

[0008] Aluminum melting furnaces are typically equipped with a large-volume melting furnace body, which can centrally store large quantities of molten aluminum to meet the needs of large-scale production. The furnace is usually equipped with a molten pool or aluminum bath, which stores liquid aluminum and transports it to the mold through aluminum pipelines or a casting system.

[0009] Furnaces are typically equipped with sophisticated temperature control devices to monitor the temperature of the molten aluminum in real time, ensuring that the melting process takes place within an appropriate temperature range, thereby improving the quality of the molten aluminum and the casting effect.

[0010] Oxide removal: Furnaces are typically equipped with slag removal devices to ensure the purity of the molten aluminum by removing surface oxides. This is crucial for the production of high-quality aluminum alloy castings.

[0011] Because the aluminum molten metal furnace has its feed inlet at the top, a feeding elevator is needed to transport the raw materials. However, existing feeding elevators are prone to material falling during transport, exhibiting low stability. Furthermore, manual operation is required during transport, increasing labor intensity and reducing safety, making them inconvenient for users and impractical. No solutions have yet been proposed to address these technical problems. Utility Model Content
